UNRELEASED](https://xenbits.xenproject.org/gitweb/?p=xen.git;a=shortlog;h=staging) - TBD - -### Changed - - Changed flexible array definitions in public I/O interface headers to not - use "1" as the number of array elements. - - On x86: - - HVM PIRQs are disabled by default. - -### Added - - On x86: - - Introduce a new x2APIC driver that uses Cluster Logical addressing mode - for IPIs and Physical addressing mode for external interrupts. - -### Removed -- caml-stubdom. It hasn't built since 2014, was pinned to Ocaml 4.02, and has - been superseded by the MirageOS/SOLO5 projects. -- /usr/bin/pygrub symlink. This was deprecated in Xen 4.2 (2012) but left for - compatibility reasons. VMs configured with bootloader="/usr/bin/pygrub" - should be updated to just bootloader="pygrub". - -## [4.18.0](https://xenbits.xenproject.org/gitweb/?p=xen.git;a=shortlog;h=RELEASE-4.18.0) - 2023-11-16 - -### Changed - - Repurpose command line gnttab_max_{maptrack_,}frames options so they don't - cap toolstack provided values. - - Ignore VCPUOP_set_singleshot_timer's VCPU_SSHOTTMR_future flag. The only - known user doesn't use it properly, leading to in-guest breakage. - - The "dom0" option is now supported on Arm and "sve=" sub-option can be used - to enable dom0 guest to use SVE/SVE2 instructions. - - Physical CPU Hotplug downgraded to Experimental and renamed "ACPI CPU - Hotplug" for clarity - -### Added - - On x86: - - On all Intel systems, MSR_ARCH_CAPS is now visible in guests, and - controllable from the VM's config file. For CPUs from ~2019 onwards, - this allows guest kernels to see details about hardware fixes for - speculative mitigations. (Backported as XSA-435 to older releases). - - xl/libxl can customize SMBIOS strings for HVM guests. - - Support for enforcing system-wide operation in Data Operand Independent - Timing Mode. - - Add Intel Hardware P-States (HWP) cpufreq driver. - - Support for features new in AMD Genoa CPUs: - - CPUID_USER_DIS (CPUID Faulting) used by Xen to control PV guest's view - of CPUID data. - - Support for features new in Intel Sapphire Rapids CPUs: - - PKS (Protection Key Supervisor) available to HVM/PVH guests. - - VM-Notify used by Xen to mitigate certain micro-architectural pipeline - livelocks, instead of crashing the entire server. - - Bus-lock detection, used by Xen to mitigate (by rate-limiting) the - system wide impact of a guest misusing atomic instructions. - - Support for features new in Intel Granite Rapids CPUs: - - AVX512-FP16. - - On Arm: - - Xen supports guests running SVE/SVE2 instructions. (Tech Preview) - - Add suport for Firmware Framework for Arm A-profile (FF-A) Mediator (Tech - Preview) - - Experimental support for dynamic addition/removal of Xen device tree - nodes using a device tree overlay binary (.dtbo). - - Introduce two new hypercalls to map the vCPU runstate and time areas by - physical rather than linear/virtual addresses. - - The project has now officially adopted 6 directives and 65 rules of MISRA-C. - -### Removed - - On x86, the "pku" command line option has been removed. It has never - behaved precisely as described, and was redundant with the unsupported - "cpuid=no-pku".

Non-case labels inside switch() bodies -are preferred to be indented the same as the block's case labels. - -White space ------------ - -Space characters are used to spread out logical statements, such as in -the condition of an if or while. Spaces are placed between the -keyword and the brackets surrounding the condition, between the -brackets and the condition itself, and around binary operators (except -the structure access operators, '.' and '->'). e.g. - -if ( (wibble & wombat) == 42 ) -{ - ... - -There should be no trailing white space at the end of lines (including -after the opening /* of a comment block). - -Line Length ------------ - -Lines should be less than 80 characters in length.

ASSERT is a way to move -detection of a bug earlier in the programming cycle; it is a -more-noticeable printk. It should only be added after one of the -other three error-handling mechanisms has been evaluated for -reliability and security. - -RATIONALE: - -It's frequently the case that code is written with the assumption that -certain conditions can never happen. There are several possible -actions programmers can take in these situations: - -* Programmers can simply not handle those cases in any way, other than -perhaps to write a comment documenting what the assumption is. - -* Programmers can try to handle the case gracefully -- fixing up -in-progress state and returning an error to the user. - -* Programmers can crash the guest. - -* Programmers can use ASSERT(), which will cause the check to be -executed in DEBUG builds, and cause the hypervisor to crash if it's -violated - -* Programmers can use BUG_ON(), which will cause the check to be -executed in both DEBUG and non-DEBUG builds, and cause the hypervisor -to crash if it's violated. - -In selecting which response to use, we want to achieve several goals: - -- To minimize risk of introducing security vulnerabilities, - particularly as the code evolves over time - -- To efficiently spend programmer time - -- To detect violations of assumptions as early as possible - -- To minimize the impact of bugs on production use cases - -The guidelines above attempt to balance these: - -- When the caller is expecting to handle errors, and there is no -broken state at the time the unexpected condition is discovered, or -when fixing the state is straightforward, then fixing up the state and -returning an error is the most robust thing to do. However, if the -caller isn't expecting to handle errors, or if the state is difficult -to fix, then returning an error may require extensive refactoring, -which is not a good use of programmer time when they're certain that -this condition cannot occur. - -- BUG_ON() will stop all hypervisor action immediately. In situations -where continuing might allow an attacker to escalate privilege, a -BUG_ON() can change a privilege escalation or information leak into a -denial-of-service (an improvement). But in situations where -continuing (say, returning an error) might be safe, then BUG_ON() can -change a benign failure into denial-of-service (a degradation). - -- domain_crash() is similar to BUG_ON(), but with a more limited -effect: it stops that domain immediately. In situations where -continuing might cause guest or hypervisor corruption, but destroying -the guest allows the hypervisor to continue, this can change a more -serious bug into a guest denial-of-service. But in situations where -returning an error might be safe, then domain_crash() can change a -benign failure into a guest denial-of-service. - -- ASSERT() will stop the hypervisor during development, but allow -hypervisor action to continue during production. In situations where -continuing will at worst result in a denial-of-service, and at best -may have little effect other than perhaps quirky behavior, using an -ASSERT() will allow violation of assumptions to be detected as soon as -possible, while not causing undue degradation in production -hypervisors. However, in situations where continuing could cause -privilege escalation or information leaks, using an ASSERT() can -introduce security vulnerabilities. - -Note however that domain_crash() has its own traps: callers far up the -call stack may not realize that the domain is now dying as a result of -an innocuous-looking operation, particularly if somewhere on the -callstack between the initial function call and the failure, no error -is returned. Using domain_crash() requires careful inspection and -documentation of the code to make sure all callers at the stack handle -a newly-dead domain gracefully. diff --git a/src/xen/CONTRIBUTING b/src/xen/CONTRIBUTING deleted file mode 100644 index 5710a8a..0000000 --- a/src/xen/CONTRIBUTING +++ /dev/null @@ -1,114 +0,0 @@ - -CONTRIBUTING -============ - -INBOUND LICENSE ---------------- - -Contributions are governed by the license that applies to relevant -specific file or by the license specified in the COPYING file, that -governs the license of its containing directory and its subdirectories. - -Most of the Xen Project code is licensed under GPLv2, but a number of -directories are primarily licensed under different licenses. - -Most notably: - - tools/libs : LGPL v2.1 - - tools/libxc : LGPL v2.1 - - tools/libxl : LGPL v2.1 - - tools/xl : LGPL v2.1 - - xen/include/public : MIT license - -See LICENSES/ for a list of licenses and SPDX tags currently used. - -When creating new components, new files, or importing code please follow -the conventions outlined below.

By contrast, the GNU General Public -License is intended to guarantee your freedom to share and change free -software--to make sure the software is free for all its users. This -General Public License applies to most of the Free Software -Foundation's software and to any other program whose authors commit to -using it. (Some other Free Software Foundation software is covered by -the GNU Library General Public License instead.) You can apply it to -your programs, too. - - When we speak of free software, we are referring to freedom, not -price. Our General Public Licenses are designed to make sure that you -have the freedom to distribute copies of free software (and charge for -this service if you wish), that you receive source code or can get it -if you want it, that you can change the software or use pieces of it -in new free programs; and that you know you can do these things. - - To protect your rights, we need to make restrictions that forbid -anyone to deny you these rights or to ask you to surrender the rights. -These restrictions translate to certain responsibilities for you if you -distribute copies of the software, or if you modify it. - - For example, if you distribute copies of such a program, whether -gratis or for a fee, you must give the recipients all the rights that -you have. You must make sure that they, too, receive or can get the -source code. And you must show them these terms so they know their -rights. - - We protect your rights with two steps: (1) copyright the software, and -(2) offer you this license which gives you legal permission to copy, -distribute and/or modify the software. - - Also, for each author's protection and ours, we want to make certain -that everyone understands that there is no warranty for this free -software. If the software is modified by someone else and passed on, we -want its recipients to know that what they have is not the original, so -that any problems introduced by others will not reflect on the original -authors' reputations. - - Finally, any free program is threatened constantly by software -patents. We wish to avoid the danger that redistributors of a free -program will individually obtain patent licenses, in effect making the -program proprietary. To prevent this, we have made it clear that any -patent must be licensed for everyone's free use or not licensed at all. - - The precise terms and conditions for copying, distribution and -modification follow. - - GNU GENERAL PUBLIC LICENSE - TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION - - 0. This License applies to any program or other work which contains -a notice placed by the copyright holder saying it may be distributed -under the terms of this General Public License. The "Program", below, -refers to any such program or work, and a "work based on the Program" -means either the Program or any derivative work under copyright law: -that is to say, a work containing the Program or a portion of it, -either verbatim or with modifications and/or translated into another -language. (Hereinafter, translation is included without limitation in -the term "modification".) Each licensee is addressed as "you". - -Activities other than copying, distribution and modification are not -covered by this License; they are outside its scope. The act of -running the Program is not restricted, and the output from the Program -is covered only if its contents constitute a work based on the -Program (independent of having been made by running the Program). -Whether that is true depends on what the Program does. - - 1. You may copy and distribute verbatim copies of the Program's -source code as you receive it, in any medium, provided that you -conspicuously and appropriately publish on each copy an appropriate -copyright notice and disclaimer of warranty; keep intact all the -notices that refer to this License and to the absence of any warranty; -and give any other recipients of the Program a copy of this License -along with the Program. - -You may charge a fee for the physical act of transferring a copy, and -you may at your option offer warranty protection in exchange for a fee. - - 2. You may modify your copy or copies of the Program or any portion -of it, thus forming a work based on the Program, and copy and -distribute such modifications or work under the terms of Section 1 -above, provided that you also meet all of these conditions: - - a) You must cause the modified files to carry prominent notices - stating that you changed the files and the date of any change. - - b) You must cause any work that you distribute or publish, that in - whole or in part contains or is derived from the Program or any - part thereof, to be licensed as a whole at no charge to all third - parties under the terms of this License. - - c) If the modified program normally reads commands interactively - when run, you must cause it, when started running for such - interactive use in the most ordinary way, to print or display an - announcement including an appropriate copyright notice and a - notice that there is no warranty (or else, saying that you provide - a warranty) and that users may redistribute the program under - these conditions, and telling the user how to view a copy of this - License. (Exception: if the Program itself is interactive but - does not normally print such an announcement, your work based on - the Program is not required to print an announcement.) - -These requirements apply to the modified work as a whole. If -identifiable sections of that work are not derived from the Program, -and can be reasonably considered independent and separate works in -themselves, then this License, and its terms, do not apply to those -sections when you distribute them as separate works. But when you -distribute the same sections as part of a whole which is a work based -on the Program, the distribution of the whole must be on the terms of -this License, whose permissions for other licensees extend to the -entire whole, and thus to each and every part regardless of who wrote it. - -Thus, it is not the intent of this section to claim rights or contest -your rights to work written entirely by you; rather, the intent is to -exercise the right to control the distribution of derivative or -collective works based on the Program. - -In addition, mere aggregation of another work not based on the Program -with the Program (or with a work based on the Program) on a volume of -a storage or distribution medium does not bring the other work under -the scope of this License. - - 3. You may copy and distribute the Program (or a work based on it, -under Section 2) in object code or executable form under the terms of -Sections 1 and 2 above provided that you also do one of the following: - - a) Accompany it with the complete corresponding machine-readable - source code, which must be distributed under the terms of Sections - 1 and 2 above on a medium customarily used for software interchange; or, - - b) Accompany it with a written offer, valid for at least three - years, to give any third party, for a charge no more than your - cost of physically performing source distribution, a complete - machine-readable copy of the corresponding source code, to be - distributed under the terms of Sections 1 and 2 above on a medium - customarily used for software interchange; or, - - c) Accompany it with the information you received as to the offer - to distribute corresponding source code. (This alternative is - allowed only for noncommercial distribution and only if you - received the program in object code or executable form with such - an offer, in accord with Subsection b above.) - -The source code for a work means the preferred form of the work for -making modifications to it. For an executable work, complete source -code means all the source code for all modules it contains, plus any -associated interface definition files, plus the scripts used to -control compilation and installation of the executable. However, as a -special exception, the source code distributed need not include -anything that is normally distributed (in either source or binary -form) with the major components (compiler, kernel, and so on) of the -operating system on which the executable runs, unless that component -itself accompanies the executable. - -If distribution of executable or object code is made by offering -access to copy from a designated place, then offering equivalent -access to copy the source code from the same place counts as -distribution of the source code, even though third parties are not -compelled to copy the source along with the object code. - - 4. You may not copy, modify, sublicense, or distribute the Program -except as expressly provided under this License. Any attempt -otherwise to copy, modify, sublicense or distribute the Program is -void, and will automatically terminate your rights under this License. -However, parties who have received copies, or rights, from you under -this License will not have their licenses terminated so long as such -parties remain in full compliance. - - 5. You are not required to accept this License, since you have not -signed it. However, nothing else grants you permission to modify or -distribute the Program or its derivative works. These actions are -prohibited by law if you do not accept this License. Therefore, by -modifying or distributing the Program (or any work based on the -Program), you indicate your acceptance of this License to do so, and -all its terms and conditions for copying, distributing or modifying -the Program or works based on it. - - 6. Each time you redistribute the Program (or any work based on the -Program), the recipient automatically receives a license from the -original licensor to copy, distribute or modify the Program subject to -these terms and conditions. You may not impose any further -restrictions on the recipients' exercise of the rights granted herein. -You are not responsible for enforcing compliance by third parties to -this License. - - 7. If, as a consequence of a court judgment or allegation of patent -infringement or for any other reason (not limited to patent issues), -conditions are imposed on you (whether by court order, agreement or -otherwise) that contradict the conditions of this License, they do not -excuse you from the conditions of this License. If you cannot -distribute so as to satisfy simultaneously your obligations under this -License and any other pertinent obligations, then as a consequence you -may not distribute the Program at all. For example, if a patent -license would not permit royalty-free redistribution of the Program by -all those who receive copies directly or indirectly through you, then -the only way you could satisfy both it and this License would be to -refrain entirely from distribution of the Program. - -If any portion of this section is held invalid or unenforceable under -any particular circumstance, the balance of the section is intended to -apply and the section as a whole is intended to apply in other -circumstances. - -It is not the purpose of this section to induce you to infringe any -patents or other property right claims or to contest validity of any -such claims; this section has the sole purpose of protecting the -integrity of the free software distribution system, which is -implemented by public license practices. Many people have made -generous contributions to the wide range of software distributed -through that system in reliance on consistent application of that -system; it is up to the author/donor to decide if he or she is willing -to distribute software through any other system and a licensee cannot -impose that choice. - -This section is intended to make thoroughly clear what is believed to -be a consequence of the rest of this License. - - 8. If the distribution and/or use of the Program is restricted in -certain countries either by patents or by copyrighted interfaces, the -original copyright holder who places the Program under this License -may add an explicit geographical distribution limitation excluding -those countries, so that distribution is permitted only in or among -countries not thus excluded. In such case, this License incorporates -the limitation as if written in the body of this License. - - 9. The Free Software Foundation may publish revised and/or new versions -of the General Public License from time to time. Such new versions will -be similar in spirit to the present version, but may differ in detail to -address new problems or concerns. - -Each version is given a distinguishing version number. If the Program -specifies a version number of this License which applies to it and "any -later version", you have the option of following the terms and conditions -either of that version or of any later version published by the Free -Software Foundation. If the Program does not specify a version number of -this License, you may choose any version ever published by the Free Software -Foundation. - - 10. If you wish to incorporate parts of the Program into other free -programs whose distribution conditions are different, write to the author -to ask for permission. For software which is copyrighted by the Free -Software Foundation, write to the Free Software Foundation; we sometimes -make exceptions for this. Our decision will be guided by the two goals -of preserving the free status of all derivatives of our free software and -of promoting the sharing and reuse of software generally. - - NO WARRANTY - - 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY -FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN -OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES -PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED -OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF -MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS -TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE -PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, -REPAIR OR CORRECTION. - - 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING -WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR -REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, -INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING -OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED -TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY -YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER -PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE -POSSIBILITY OF SUCH DAMAGES. - - END OF TERMS AND CONDITIONS - - How to Apply These Terms to Your New Programs - - If you develop a new program, and you want it to be of the greatest -possible use to the public, the best way to achieve this is to make it -free software which everyone can redistribute and change under these terms. - - To do so, attach the following notices to the program. It is safest -to attach them to the start of each source file to most effectively -convey the exclusion of warranty; and each file should have at least -the "copyright" line and a pointer to where the full notice is found. - - - Copyright (C) - - This program is free software; you can redistribute it and/or modify - it under the terms of the GNU General Public License as published by - the Free Software Foundation; either version 2 of the License, or - (at your option) any later version. - - This program is distributed in the hope that it will be useful, - but WITHOUT ANY WARRANTY; without even the implied warranty of - MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the - GNU General Public License for more details. - - You should have received a copy of the GNU General Public License - along with this program; if not, write to the Free Software - Foundation, Inc., 51 Franklin St, Fifth Floor, Boston, MA 02110-1301 USA - - -Also add information on how to contact you by electronic and paper mail. - -If the program is interactive, make it output a short notice like this -when it starts in an interactive mode: - - Gnomovision version 69, Copyright (C) year name of author - Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. - This is free software, and you are welcome to redistribute it - under certain conditions; type `show c' for details. - -The hypothetical commands `show w' and `show c' should show the appropriate -parts of the General Public License. Of course, the commands you use may -be called something other than `show w' and `show c'; they could even be -mouse-clicks or menu items--whatever suits your program. - -You should also get your employer (if you work as a programmer) or your -school, if any, to sign a "copyright disclaimer" for the program, if -necessary. Here is a sample; alter the names: - - Yoyodyne, Inc., hereby disclaims all copyright interest in the program - `Gnomovision' (which makes passes at compilers) written by James Hacker. - - , 1 April 1989 - Ty Coon, President of Vice - -This General Public License does not permit incorporating your program into -proprietary programs.

Our -General Public Licenses are designed to make sure that you have the freedom -to distribute copies of free software (and charge for this service if you -wish), that you receive source code or can get it if you want it, that you -can change the software or use pieces of it in new free programs; and that -you know you can do these things. - -To protect your rights, we need to make restrictions that forbid anyone to -deny you these rights or to ask you to surrender the rights. These -restrictions translate to certain responsibilities for you if you -distribute copies of the library, or if you modify it. - -For example, if you distribute copies of the library, whether gratis or for -a fee, you must give the recipients all the rights that we gave you. You -must make sure that they, too, receive or can get the source code. If you -link a program with the library, you must provide complete object files to -the recipients so that they can relink them with the library, after making -changes to the library and recompiling it. And you must show them these -terms so they know their rights. - -Our method of protecting your rights has two steps: (1) copyright the -library, and (2) offer you this license which gives you legal permission to -copy, distribute and/or modify the library. - -Also, for each distributor's protection, we want to make certain that -everyone understands that there is no warranty for this free library. If -the library is modified by someone else and passed on, we want its -recipients to know that what they have is not the original version, so that -any problems introduced by others will not reflect on the original authors' -reputations. - -Finally, any free program is threatened constantly by software patents. We -wish to avoid the danger that companies distributing free software will -individually obtain patent licenses, thus in effect transforming the -program into proprietary software. To prevent this, we have made it clear -that any patent must be licensed for everyone's free use or not licensed at -all. - -Most GNU software, including some libraries, is covered by the ordinary GNU -General Public License, which was designed for utility programs. This -license, the GNU Library General Public License, applies to certain -designated libraries. This license is quite different from the ordinary -one; be sure to read it in full, and don't assume that anything in it is -the same as in the ordinary license. - -The reason we have a separate public license for some libraries is that -they blur the distinction we usually make between modifying or adding to a -program and simply using it. Linking a program with a library, without -changing the library, is in some sense simply using the library, and is -analogous to running a utility program or application program. However, in -a textual and legal sense, the linked executable is a combined work, a -derivative of the original library, and the ordinary General Public License -treats it as such. - -Because of this blurred distinction, using the ordinary General Public -License for libraries did not effectively promote software sharing, because -most developers did not use the libraries. We concluded that weaker -conditions might promote sharing better. - -However, unrestricted linking of non-free programs would deprive the users -of those programs of all benefit from the free status of the libraries -themselves. This Library General Public License is intended to permit -developers of non-free programs to use free libraries, while preserving -your freedom as a user of such programs to change the free libraries that -are incorporated in them. (We have not seen how to achieve this as regards -changes in header files, but we have achieved it as regards changes in the -actual functions of the Library.) The hope is that this will lead to faster -development of free libraries. - -The precise terms and conditions for copying, distribution and modification -follow. Pay close attention to the difference between a "work based on the -library" and a "work that uses the library". The former contains code -derived from the library, while the latter only works together with the -library. - -Note that it is possible for a library to be covered by the ordinary -General Public License rather than by this special one. - -TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION - -0. This License Agreement applies to any software library which contains a - notice placed by the copyright holder or other authorized party saying - it may be distributed under the terms of this Library General Public - License (also called "this License"). Each licensee is addressed as - "you". - - A "library" means a collection of software functions and/or data - prepared so as to be conveniently linked with application programs - (which use some of those functions and data) to form executables. - - The "Library", below, refers to any such software library or work which - has been distributed under these terms. A "work based on the Library" - means either the Library or any derivative work under copyright law: - that is to say, a work containing the Library or a portion of it, either - verbatim or with modifications and/or translated straightforwardly into - another language. (Hereinafter, translation is included without - limitation in the term "modification".) - - "Source code" for a work means the preferred form of the work for making - modifications to it. For a library, complete source code means all the - source code for all modules it contains, plus any associated interface - definition files, plus the scripts used to control compilation and - installation of the library. - - Activities other than copying, distribution and modification are not - covered by this License; they are outside its scope. The act of running - a program using the Library is not restricted, and output from such a - program is covered only if its contents constitute a work based on the - Library (independent of the use of the Library in a tool for writing - it). Whether that is true depends on what the Library does and what the - program that uses the Library does. - -1. You may copy and distribute verbatim copies of the Library's complete - source code as you receive it, in any medium, provided that you - conspicuously and appropriately publish on each copy an appropriate - copyright notice and disclaimer of warranty; keep intact all the notices - that refer to this License and to the absence of any warranty; and - distribute a copy of this License along with the Library. - - You may charge a fee for the physical act of transferring a copy, and - you may at your option offer warranty protection in exchange for a fee. - -2. You may modify your copy or copies of the Library or any portion of it, - thus forming a work based on the Library, and copy and distribute such - modifications or work under the terms of Section 1 above, provided that - you also meet all of these conditions: - - a) The modified work must itself be a software library. - - b) You must cause the files modified to carry prominent notices stating - that you changed the files and the date of any change. - - c) You must cause the whole of the work to be licensed at no charge to - all third parties under the terms of this License. - - d) If a facility in the modified Library refers to a function or a table - of data to be supplied by an application program that uses the - facility, other than as an argument passed when the facility is - invoked, then you must make a good faith effort to ensure that, in - the event an application does not supply such function or table, the - facility still operates, and performs whatever part of its purpose - remains meaningful. - - (For example, a function in a library to compute square roots has a - purpose that is entirely well-defined independent of the - application. Therefore, Subsection 2d requires that any - application-supplied function or table used by this function must be - optional: if the application does not supply it, the square root - function must still compute square roots.) - - These requirements apply to the modified work as a whole. If - identifiable sections of that work are not derived from the Library, and - can be reasonably considered independent and separate works in - themselves, then this License, and its terms, do not apply to those - sections when you distribute them as separate works. But when you - distribute the same sections as part of a whole which is a work based on - the Library, the distribution of the whole must be on the terms of this - License, whose permissions for other licensees extend to the entire - whole, and thus to each and every part regardless of who wrote it. - - Thus, it is not the intent of this section to claim rights or contest - your rights to work written entirely by you; rather, the intent is to - exercise the right to control the distribution of derivative or - collective works based on the Library. - - In addition, mere aggregation of another work not based on the Library - with the Library (or with a work based on the Library) on a volume of a - storage or distribution medium does not bring the other work under the - scope of this License. - -3. You may opt to apply the terms of the ordinary GNU General Public - License instead of this License to a given copy of the Library. To do - this, you must alter all the notices that refer to this License, so that - they refer to the ordinary GNU General Public License, version 2, - instead of to this License. (If a newer version than version 2 of the - ordinary GNU General Public License has appeared, then you can specify - that version instead if you wish.) Do not make any other change in these - notices. - - Once this change is made in a given copy, it is irreversible for that - copy, so the ordinary GNU General Public License applies to all - subsequent copies and derivative works made from that copy. - - This option is useful when you wish to copy part of the code of the - Library into a program that is not a library. - -4. You may copy and distribute the Library (or a portion or derivative of - it, under Section 2) in object code or executable form under the terms - of Sections 1 and 2 above provided that you accompany it with the - complete corresponding machine-readable source code, which must be - distributed under the terms of Sections 1 and 2 above on a medium - customarily used for software interchange. - - If distribution of object code is made by offering access to copy from a - designated place, then offering equivalent access to copy the source - code from the same place satisfies the requirement to distribute the - source code, even though third parties are not compelled to copy the - source along with the object code. - -5. A program that contains no derivative of any portion of the Library, but - is designed to work with the Library by being compiled or linked with - it, is called a "work that uses the Library". Such a work, in isolation, - is not a derivative work of the Library, and therefore falls outside the - scope of this License. - - However, linking a "work that uses the Library" with the Library creates - an executable that is a derivative of the Library (because it contains - portions of the Library), rather than a "work that uses the - library". The executable is therefore covered by this License. Section 6 - states terms for distribution of such executables. - - When a "work that uses the Library" uses material from a header file - that is part of the Library, the object code for the work may be a - derivative work of the Library even though the source code is - not. Whether this is true is especially significant if the work can be - linked without the Library, or if the work is itself a library. The - threshold for this to be true is not precisely defined by law. - - If such an object file uses only numerical parameters, data structure - layouts and accessors, and small macros and small inline functions (ten - lines or less in length), then the use of the object file is - unrestricted, regardless of whether it is legally a derivative - work. (Executables containing this object code plus portions of the - Library will still fall under Section 6.) - - Otherwise, if the work is a derivative of the Library, you may - distribute the object code for the work under the terms of Section - 6. Any executables containing that work also fall under Section 6, - whether or not they are linked directly with the Library itself. - -6. As an exception to the Sections above, you may also compile or link a - "work that uses the Library" with the Library to produce a work - containing portions of the Library, and distribute that work under terms - of your choice, provided that the terms permit modification of the work - for the customer's own use and reverse engineering for debugging such - modifications. - - You must give prominent notice with each copy of the work that the - Library is used in it and that the Library and its use are covered by - this License. You must supply a copy of this License. If the work during - execution displays copyright notices, you must include the copyright - notice for the Library among them, as well as a reference directing the - user to the copy of this License. Also, you must do one of these things: - - a) Accompany the work with the complete corresponding machine-readable - source code for the Library including whatever changes were used in - the work (which must be distributed under Sections 1 and 2 above); - and, if the work is an executable linked with the Library, with the - complete machine-readable "work that uses the Library", as object - code and/or source code, so that the user can modify the Library and - then relink to produce a modified executable containing the modified - Library. (It is understood that the user who changes the contents of - definitions files in the Library will not necessarily be able to - recompile the application to use the modified definitions.) - - b) Accompany the work with a written offer, valid for at least three - years, to give the same user the materials specified in Subsection - 6a, above, for a charge no more than the cost of performing this - distribution. - - c) If distribution of the work is made by offering access to copy from a - designated place, offer equivalent access to copy the above specified - materials from the same place. - - d) Verify that the user has already received a copy of these materials - or that you have already sent this user a copy. - - For an executable, the required form of the "work that uses the Library" - must include any data and utility programs needed for reproducing the - executable from it. However, as a special exception, the source code - distributed need not include anything that is normally distributed (in - either source or binary form) with the major components (compiler, - kernel, and so on) of the operating system on which the executable runs, - unless that component itself accompanies the executable. - - It may happen that this requirement contradicts the license restrictions - of other proprietary libraries that do not normally accompany the - operating system. Such a contradiction means you cannot use both them - and the Library together in an executable that you distribute. - -7. You may place library facilities that are a work based on the Library - side-by-side in a single library together with other library facilities - not covered by this License, and distribute such a combined library, - provided that the separate distribution of the work based on the Library - and of the other library facilities is otherwise permitted, and provided - that you do these two things: - - a) Accompany the combined library with a copy of the same work based on - the Library, uncombined with any other library facilities. This must - be distributed under the terms of the Sections above. - - b) Give prominent notice with the combined library of the fact that part - of it is a work based on the Library, and explaining where to find - the accompanying uncombined form of the same work. - -8. You may not copy, modify, sublicense, link with, or distribute the - Library except as expressly provided under this License. Any attempt - otherwise to copy, modify, sublicense, link with, or distribute the - Library is void, and will automatically terminate your rights under this - License. However, parties who have received copies, or rights, from you - under this License will not have their licenses terminated so long as - such parties remain in full compliance. - -9. You are not required to accept this License, since you have not signed - it. However, nothing else grants you permission to modify or distribute - the Library or its derivative works. These actions are prohibited by law - if you do not accept this License. Therefore, by modifying or - distributing the Library (or any work based on the Library), you - indicate your acceptance of this License to do so, and all its terms and - conditions for copying, distributing or modifying the Library or works - based on it. - -10. Each time you redistribute the Library (or any work based on the - Library), the recipient automatically receives a license from the - original licensor to copy, distribute, link with or modify the Library - subject to these terms and conditions. You may not impose any further - restrictions on the recipients' exercise of the rights granted - herein. You are not responsible for enforcing compliance by third - parties to this License. - -11. If, as a consequence of a court judgment or allegation of patent - infringement or for any other reason (not limited to patent issues), - conditions are imposed on you (whether by court order, agreement or - otherwise) that contradict the conditions of this License, they do not - excuse you from the conditions of this License. If you cannot - distribute so as to satisfy simultaneously your obligations under this - License and any other pertinent obligations, then as a consequence you - may not distribute the Library at all. For example, if a patent license - would not permit royalty-free redistribution of the Library by all - those who receive copies directly or indirectly through you, then the - only way you could satisfy both it and this License would be to refrain - entirely from distribution of the Library. - - If any portion of this section is held invalid or unenforceable under - any particular circumstance, the balance of the section is intended to - apply, and the section as a whole is intended to apply in other - circumstances. - - It is not the purpose of this section to induce you to infringe any - patents or other property right claims or to contest validity of any - such claims; this section has the sole purpose of protecting the - integrity of the free software distribution system which is implemented - by public license practices. Many people have made generous - contributions to the wide range of software distributed through that - system in reliance on consistent application of that system; it is up - to the author/donor to decide if he or she is willing to distribute - software through any other system and a licensee cannot impose that - choice. - - This section is intended to make thoroughly clear what is believed to - be a consequence of the rest of this License. - -12. If the distribution and/or use of the Library is restricted in certain - countries either by patents or by copyrighted interfaces, the original - copyright holder who places the Library under this License may add an - explicit geographical distribution limitation excluding those - countries, so that distribution is permitted only in or among countries - not thus excluded. In such case, this License incorporates the - limitation as if written in the body of this License. - -13. The Free Software Foundation may publish revised and/or new versions of - the Library General Public License from time to time. Such new versions - will be similar in spirit to the present version, but may differ in - detail to address new problems or concerns. - - Each version is given a distinguishing version number. If the Library - specifies a version number of this License which applies to it and "any - later version", you have the option of following the terms and - conditions either of that version or of any later version published by - the Free Software Foundation. If the Library does not specify a license - version number, you may choose any version ever published by the Free - Software Foundation. - -14. If you wish to incorporate parts of the Library into other free - programs whose distribution conditions are incompatible with these, - write to the author to ask for permission. For software which is - copyrighted by the Free Software Foundation, write to the Free Software - Foundation; we sometimes make exceptions for this. Our decision will be - guided by the two goals of preserving the free status of all - derivatives of our free software and of promoting the sharing and reuse - of software generally. - -NO WARRANTY - -15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY - FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN - OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES - PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER - EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED - WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE - ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE LIBRARY IS WITH - YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL - NECESSARY SERVICING, REPAIR OR CORRECTION. - -16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING - WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR - REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU FOR - DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL - DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE LIBRARY - (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED - INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF - THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF SUCH HOLDER OR - OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. - -END OF TERMS AND CONDITIONS - -How to Apply These Terms to Your New Libraries - -If you develop a new library, and you want it to be of the greatest -possible use to the public, we recommend making it free software that -everyone can redistribute and change. You can do so by permitting -redistribution under these terms (or, alternatively, under the terms of the -ordinary General Public License). - -To apply these terms, attach the following notices to the library. It is -safest to attach them to the start of each source file to most effectively -convey the exclusion of warranty; and each file should have at least the -"copyright" line and a pointer to where the full notice is found. - -one line to give the library's name and an idea of what it does. -Copyright (C) year name of author - -This library is free software; you can redistribute it and/or modify it -under the terms of the GNU Library General Public License as published by -the Free Software Foundation; either version 2 of the License, or (at your -option) any later version. - -This library is distributed in the hope that it will be useful, but WITHOUT -ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or -FITNESS FOR A PARTICULAR PURPOSE.

By contrast, the GNU General Public Licenses are -intended to guarantee your freedom to share and change free software--to -make sure the software is free for all its users. - -This license, the Lesser General Public License, applies to some specially -designated software packages--typically libraries--of the Free Software -Foundation and other authors who decide to use it. You can use it too, but -we suggest you first think carefully about whether this license or the -ordinary General Public License is the better strategy to use in any -particular case, based on the explanations below. - -When we speak of free software, we are referring to freedom of use, not -price. Our General Public Licenses are designed to make sure that you have -the freedom to distribute copies of free software (and charge for this -service if you wish); that you receive source code or can get it if you -want it; that you can change the software and use pieces of it in new free -programs; and that you are informed that you can do these things. - -To protect your rights, we need to make restrictions that forbid -distributors to deny you these rights or to ask you to surrender these -rights.

If you -link other code with the library, you must provide complete object files to -the recipients, so that they can relink them with the library after making -changes to the library and recompiling it. And you must show them these -terms so they know their rights. - -We protect your rights with a two-step method: (1) we copyright the -library, and (2) we offer you this license, which gives you legal -permission to copy, distribute and/or modify the library. - -To protect each distributor, we want to make it very clear that there is no -warranty for the free library. Also, if the library is modified by someone -else and passed on, the recipients should know that what they have is not -the original version, so that the original author's reputation will not be -affected by problems that might be introduced by others. - -Finally, software patents pose a constant threat to the existence of any -free program. We wish to make sure that a company cannot effectively -restrict the users of a free program by obtaining a restrictive license -from a patent holder. Therefore, we insist that any patent license obtained -for a version of the library must be consistent with the full freedom of -use specified in this license. - -Most GNU software, including some libraries, is covered by the ordinary GNU -General Public License. This license, the GNU Lesser General Public -License, applies to certain designated libraries, and is quite different -from the ordinary General Public License. We use this license for certain -libraries in order to permit linking those libraries into non-free -programs. - -When a program is linked with a library, whether statically or using a -shared library, the combination of the two is legally speaking a combined -work, a derivative of the original library. The ordinary General Public -License therefore permits such linking only if the entire combination fits -its criteria of freedom. The Lesser General Public License permits more lax -criteria for linking other code with the library. - -We call this license the "Lesser" General Public License because it does -Less to protect the user's freedom than the ordinary General Public -License. It also provides other free software developers Less of an -advantage over competing non-free programs. These disadvantages are the -reason we use the ordinary General Public License for many -libraries. However, the Lesser license provides advantages in certain -special circumstances. - -For example, on rare occasions, there may be a special need to encourage -the widest possible use of a certain library, so that it becomes a de-facto -standard. To achieve this, non-free programs must be allowed to use the -library. A more frequent case is that a free library does the same job as -widely used non-free libraries. In this case, there is little to gain by -limiting the free library to free software only, so we use the Lesser -General Public License. - -In other cases, permission to use a particular library in non-free programs -enables a greater number of people to use a large body of free -software. For example, permission to use the GNU C Library in non-free -programs enables many more people to use the whole GNU operating system, as -well as its variant, the GNU/Linux operating system. - -Although the Lesser General Public License is Less protective of the users' -freedom, it does ensure that the user of a program that is linked with the -Library has the freedom and the wherewithal to run that program using a -modified version of the Library. - -The precise terms and conditions for copying, distribution and modification -follow. Pay close attention to the difference between a "work based on the -library" and a "work that uses the library". The former contains code -derived from the library, whereas the latter must be combined with the -library in order to run. - -TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION - -0. This License Agreement applies to any software library or other program - which contains a notice placed by the copyright holder or other - authorized party saying it may be distributed under the terms of this - Lesser General Public License (also called "this License").

Do not make any other change in these - notices. - - Once this change is made in a given copy, it is irreversible for that - copy, so the ordinary GNU General Public License applies to all - subsequent copies and derivative works made from that copy. - - This option is useful when you wish to copy part of the code of the - Library into a program that is not a library. - -4. You may copy and distribute the Library (or a portion or derivative of - it, under Section 2) in object code or executable form under the terms - of Sections 1 and 2 above provided that you accompany it with the - complete corresponding machine-readable source code, which must be - distributed under the terms of Sections 1 and 2 above on a medium - customarily used for software interchange. - - If distribution of object code is made by offering access to copy from a - designated place, then offering equivalent access to copy the source - code from the same place satisfies the requirement to distribute the - source code, even though third parties are not compelled to copy the - source along with the object code. - -5. A program that contains no derivative of any portion of the Library, but - is designed to work with the Library by being compiled or linked with - it, is called a "work that uses the Library". Such a work, in isolation, - is not a derivative work of the Library, and therefore falls outside the - scope of this License. - - However, linking a "work that uses the Library" with the Library creates - an executable that is a derivative of the Library (because it contains - portions of the Library), rather than a "work that uses the - library". The executable is therefore covered by this License. Section 6 - states terms for distribution of such executables. - - When a "work that uses the Library" uses material from a header file - that is part of the Library, the object code for the work may be a - derivative work of the Library even though the source code is - not. Whether this is true is especially significant if the work can be - linked without the Library, or if the work is itself a library. The - threshold for this to be true is not precisely defined by law. - - If such an object file uses only numerical parameters, data structure - layouts and accessors, and small macros and small inline functions (ten - lines or less in length), then the use of the object file is - unrestricted, regardless of whether it is legally a derivative - work. (Executables containing this object code plus portions of the - Library will still fall under Section 6.) - - Otherwise, if the work is a derivative of the Library, you may - distribute the object code for the work under the terms of Section - 6. Any executables containing that work also fall under Section 6, - whether or not they are linked directly with the Library itself. - -6. As an exception to the Sections above, you may also combine or link a - "work that uses the Library" with the Library to produce a work - containing portions of the Library, and distribute that work under terms - of your choice, provided that the terms permit modification of the work - for the customer's own use and reverse engineering for debugging such - modifications. - - You must give prominent notice with each copy of the work that the - Library is used in it and that the Library and its use are covered by - this License. You must supply a copy of this License. If the work during - execution displays copyright notices, you must include the copyright - notice for the Library among them, as well as a reference directing the - user to the copy of this License. Also, you must do one of these things: - - a) Accompany the work with the complete corresponding machine-readable - source code for the Library including whatever changes were used in - the work (which must be distributed under Sections 1 and 2 above); - and, if the work is an executable linked with the Library, with the - complete machine-readable "work that uses the Library", as object - code and/or source code, so that the user can modify the Library and - then relink to produce a modified executable containing the modified - Library. (It is understood that the user who changes the contents of - definitions files in the Library will not necessarily be able to - recompile the application to use the modified definitions.) - - b) Use a suitable shared library mechanism for linking with the - Library. A suitable mechanism is one that (1) uses at run time a copy - of the library already present on the user's computer system, rather - than copying library functions into the executable, and (2) will - operate properly with a modified version of the library, if the user - installs one, as long as the modified version is interface-compatible - with the version that the work was made with. - - c) Accompany the work with a written offer, valid for at least three - years, to give the same user the materials specified in Subsection - 6a, above, for a charge no more than the cost of performing this - distribution. - - d) If distribution of the work is made by offering access to copy from a - designated place, offer equivalent access to copy the above specified - materials from the same place. - - e) Verify that the user has already received a copy of these materials - or that you have already sent this user a copy. - - For an executable, the required form of the "work that uses the Library" - must include any data and utility programs needed for reproducing the - executable from it. However, as a special exception, the materials to be - distributed need not include anything that is normally distributed (in - either source or binary form) with the major components (compiler, - kernel, and so on) of the operating system on which the executable runs, - unless that component itself accompanies the executable. - - It may happen that this requirement contradicts the license restrictions - of other proprietary libraries that do not normally accompany the - operating system. Such a contradiction means you cannot use both them - and the Library together in an executable that you distribute. - -7. You may place library facilities that are a work based on the Library - side-by-side in a single library together with other library facilities - not covered by this License, and distribute such a combined library, - provided that the separate distribution of the work based on the Library - and of the other library facilities is otherwise permitted, and provided - that you do these two things: - - a) Accompany the combined library with a copy of the same work based on - the Library, uncombined with any other library facilities. This must - be distributed under the terms of the Sections above. - - b) Give prominent notice with the combined library of the fact that part - of it is a work based on the Library, and explaining where to find - the accompanying uncombined form of the same work. - -8. You may not copy, modify, sublicense, link with, or distribute the - Library except as expressly provided under this License. Any attempt - otherwise to copy, modify, sublicense, link with, or distribute the - Library is void, and will automatically terminate your rights under this - License. However, parties who have received copies, or rights, from you - under this License will not have their licenses terminated so long as - such parties remain in full compliance. - -9. You are not required to accept this License, since you have not signed - it. However, nothing else grants you permission to modify or distribute - the Library or its derivative works. These actions are prohibited by law - if you do not accept this License. Therefore, by modifying or - distributing the Library (or any work based on the Library), you - indicate your acceptance of this License to do so, and all its terms and - conditions for copying, distributing or modifying the Library or works - based on it. - -10. Each time you redistribute the Library (or any work based on the - Library), the recipient automatically receives a license from the - original licensor to copy, distribute, link with or modify the Library - subject to these terms and conditions. You may not impose any further - restrictions on the recipients' exercise of the rights granted - herein. You are not responsible for enforcing compliance by third - parties with this License. - -11. If, as a consequence of a court judgment or allegation of patent - infringement or for any other reason (not limited to patent issues), - conditions are imposed on you (whether by court order, agreement or - otherwise) that contradict the conditions of this License, they do not - excuse you from the conditions of this License. If you cannot - distribute so as to satisfy simultaneously your obligations under this - License and any other pertinent obligations, then as a consequence you - may not distribute the Library at all. For example, if a patent license - would not permit royalty-free redistribution of the Library by all - those who receive copies directly or indirectly through you, then the - only way you could satisfy both it and this License would be to refrain - entirely from distribution of the Library. - - If any portion of this section is held invalid or unenforceable under - any particular circumstance, the balance of the section is intended to - apply, and the section as a whole is intended to apply in other - circumstances. - - It is not the purpose of this section to induce you to infringe any - patents or other property right claims or to contest validity of any - such claims; this section has the sole purpose of protecting the - integrity of the free software distribution system which is implemented - by public license practices. Many people have made generous - contributions to the wide range of software distributed through that - system in reliance on consistent application of that system; it is up - to the author/donor to decide if he or she is willing to distribute - software through any other system and a licensee cannot impose that - choice. - - This section is intended to make thoroughly clear what is believed to - be a consequence of the rest of this License. - -12. If the distribution and/or use of the Library is restricted in certain - countries either by patents or by copyrighted interfaces, the original - copyright holder who places the Library under this License may add an - explicit geographical distribution limitation excluding those - countries, so that distribution is permitted only in or among countries - not thus excluded. In such case, this License incorporates the - limitation as if written in the body of this License. - -13. The Free Software Foundation may publish revised and/or new versions of - the Lesser General Public License from time to time. Such new versions - will be similar in spirit to the present version, but may differ in - detail to address new problems or concerns. - - Each version is given a distinguishing version number. If the Library - specifies a version number of this License which applies to it and "any - later version", you have the option of following the terms and - conditions either of that version or of any later version published by - the Free Software Foundation. If the Library does not specify a license - version number, you may choose any version ever published by the Free - Software Foundation. - -14. If you wish to incorporate parts of the Library into other free - programs whose distribution conditions are incompatible with these, - write to the author to ask for permission. For software which is - copyrighted by the Free Software Foundation, write to the Free Software - Foundation; we sometimes make exceptions for this. Our decision will be - guided by the two goals of preserving the free status of all - derivatives of our free software and of promoting the sharing and reuse - of software generally. - -NO WARRANTY - -15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY - FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN - OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES - PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER - EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED - WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE - ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE LIBRARY IS WITH - YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL - NECESSARY SERVICING, REPAIR OR CORRECTION. - -16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING - WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR - REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU FOR - DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL - DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE LIBRARY - (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED - INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF - THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF SUCH HOLDER OR - OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. - -END OF TERMS AND CONDITIONS - -How to Apply These Terms to Your New Libraries - -If you develop a new library, and you want it to be of the greatest -possible use to the public, we recommend making it free software that -everyone can redistribute and change. You can do so by permitting -redistribution under these terms (or, alternatively, under the terms of the -ordinary General Public License). - -To apply these terms, attach the following notices to the library. It is -safest to attach them to the start of each source file to most effectively -convey the exclusion of warranty; and each file should have at least the -"copyright" line and a pointer to where the full notice is found. - -one line to give the library's name and an idea of what it does. -Copyright (C) year name of author - -This library is free software; you can redistribute it and/or modify it -under the terms of the GNU Lesser General Public License as published by -the Free Software Foundation; either version 2.1 of the License, or (at -your option) any later version. - -This library is distributed in the hope that it will be useful, but WITHOUT -ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or -FITNESS FOR A PARTICULAR PURPOSE.

Remember to copy the appropriate stable branch maintainer who -will be listed in this section of the MAINTAINERS file in the -appropriate branch. - - Unstable Subsystem Maintainers - ============================== - -Descriptions of section entries: - - M: Maintainer: FullName - Maintainers should be CCed on patches. At least one of them - needs to approve changes to the covered files. - R: Designated reviewer: FullName - Reviewers should be CCed on patches. However, they do not - have a formal governance role, and are listed here - simply because of their own request. - L: Mailing list that is relevant to this area - W: Web-page with status/info - T: SCM tree type and location. Type is one of: git, hg, quilt, stgit. - S: Status, one of the following: - Supported: Someone is actually paid to look after this. - Maintained: Someone actually looks after it. - Odd Fixes: It has a maintainer but they don't have time to do - much other than throw the odd patch in. See below.. - Orphan: No current maintainer [but maybe you could take the - role as you write your new code]. - Obsolete: Old code. Something tagged obsolete generally means - it has been replaced by a better system and you - should be using that. - F: Files and directories with wildcard patterns. - A trailing slash includes all files and subdirectory files. - F: drivers/net/ all files in and below drivers/net - F: drivers/net/* all files in drivers/net, but not below - F: */net/* all files in "any top level directory"/net - One pattern per line.

Multiple K: lines acceptable. - V: Version identifier that must be under THE REST and follows - the format: - xen-maintainers- - - - Check-in policy - =============== - -In order for a patch to be checked in, in general, several conditions -must be met: - -1. In order to get a change to a given file committed, it must have - the approval of at least one maintainer of that file. - - A patch of course needs Acks from the maintainers of each file that - it changes; so a patch which changes xen/arch/x86/traps.c, - xen/arch/x86/mm/p2m.c, and xen/arch/x86/mm/shadow/multi.c would - require an Ack from each of the three sets of maintainers. - - See below for rules on nested maintainership. - -2. Each change must have appropriate approval from someone other than - the person who wrote it. This can be either: - - a. An Acked-by from a maintainer of the code being touched (a - co-maintainer if available, or a more general level maintainer if - not available; see the secton on nested maintainership) - - b. A Reviewed-by by anyone of suitable stature in the community - -3. Sufficient time must have been given for anyone to respond. This - depends in large part upon the urgency and nature of the patch. - For a straightforward uncontroversial patch, a day or two may be - sufficient; for a controversial patch, a week or two may be better. - -4. There must be no "open" objections. - -In a case where one person submits a patch and a maintainer gives an -Ack, the Ack stands in for both the approval requirement (#1) and the -Acked-by-non-submitter requirement (#2). - -In a case where a maintainer themselves submits a patch, the -Signed-off-by meets the approval requirement (#1); so a Review -from anyone in the community suffices for requirement #2. - -Before a maintainer checks in their own patch with another community -member's R-b but no co-maintainer Ack, it is especially important to -give their co-maintainer opportunity to give feedback, perhaps -declaring their intention to check it in without their co-maintainers -ack a day before doing so. - -In the case where two people collaborate on a patch, at least one of -whom is a maintainer -- typically where one maintainer will do an -early version of the patch, and another maintainer will pick it up and -revise it -- there should be two Signed-off-by's and one Acked-by or -Reviewed-by; with the maintainer who did the most recent change -sending the patch, and an Acked-by or Reviewed-by coming from the -maintainer who did not most recently edit the patch. This satisfies -the requirement #2 because a) the Signed-off-by of the sender approves -the final version of the patch; including all parts of the patch that -the sender did not write b) the Reviewed-by approves the final version -of the patch, including all patches that the reviewer did not write. -Thus all code in the patch has been approved by someone who did not -write it. - -Maintainers may choose to override non-maintainer objections in the -case that consensus can't be reached. - -As always, no policy can cover all possible situations. In -exceptional circumstances, committers may commit a patch in absence of -one or more of the above requirements, if they are reasonably -confident that the other maintainers will approve of their decision in -retrospect. - - The meaning of nesting - ====================== - -Many maintainership areas are "nested": for example, there are entries -for xen/arch/x86 as well as xen/arch/x86/mm, and even -xen/arch/x86/mm/shadow; and there is a section at the end called "THE -REST" which lists all committers. The meaning of nesting is that: - -1. Under normal circumstances, the Ack of the most specific maintainer -is both necessary and sufficient to get a change to a given file -committed. So a change to xen/arch/x86/mm/shadow/multi.c requires the -the Ack of the xen/arch/x86/mm/shadow maintainer for that part of the -patch, but would not require the Ack of the xen/arch/x86 maintainer or -the xen/arch/x86/mm maintainer. - -2. In unusual circumstances, a more general maintainer's Ack can stand -in for or even overrule a specific maintainer's Ack. Unusual -circumstances might include: - - The patch is fixing a high-priority issue causing immediate pain, - and the more specific maintainer is not available. - - The more specific maintainer has not responded either to the - original patch, nor to "pings", within a reasonable amount of time. - - The more general maintainer wants to overrule the more specific - maintainer on some issue. (This should be exceptional.) - - In the case of a disagreement between maintainers, THE REST can - settle the matter by majority vote. (This should be very exceptional - indeed.) - - -Maintainers List (try to look for most precise areas first) - - ----------------------------------- - -ACPI -M: Jan Beulich -S: Supported -F: xen/arch/x86/acpi/ -F: xen/drivers/acpi/ -F: xen/include/acpi/ -F: tools/libacpi/ - -AMD IOMMU -M: Jan Beulich -M: Andrew Cooper -S: Maintained -F: xen/drivers/passthrough/amd/ - -AMD SVM -M: Jan Beulich -M: Andrew Cooper -S: Supported -F: xen/arch/x86/hvm/svm/ -F: xen/arch/x86/cpu/vpmu_amd.c - -ARGO -M: Christopher Clark -S: Maintained -F: xen/include/public/argo.h -F: xen/include/xen/argo.h -F: xen/common/argo.c - -ARINC653 SCHEDULER -M: Nathan Studer -M: Stewart Hildebrand -S: Supported -L: xen-devel@dornerworks.com -F: xen/common/sched/arinc653.c -F: tools/libs/ctrl/xc_arinc653.c - -ARM (W/ VIRTUALISATION EXTENSIONS) ARCHITECTURE -M: Stefano Stabellini -M: Julien Grall -M: Bertrand Marquis -M: Michal Orzel -R: Volodymyr Babchuk -S: Supported -L: xen-devel@lists.xenproject.org -F: docs/misc/arm/ -F: xen/arch/arm/ -F: xen/drivers/char/arm-uart.c -F: xen/drivers/char/cadence-uart.c -F: xen/drivers/char/exynos4210-uart.c -F: xen/drivers/char/imx-lpuart.c -F: xen/drivers/char/meson-uart.c -F: xen/drivers/char/mvebu-uart.c -F: xen/drivers/char/omap-uart.c -F: xen/drivers/char/pl011.c -F: xen/drivers/char/scif-uart.c -F: xen/drivers/passthrough/arm/ -F: xen/include/public/arch-arm/ -F: xen/include/public/arch-arm.h - -ARM SMMU -M: Julien Grall -M: Rahul Singh -S: Supported -F: xen/drivers/passthrough/arm/smmu.c - -ARM SMMUv3 -M: Bertrand Marquis -M: Rahul Singh -S: Supported -F: xen/drivers/passthrough/arm/smmu-v3.c - -Change Log -M: Oleksii Kurochko -R: Community Manager -S: Maintained -F: CHANGELOG.md - -Continuous Integration (CI) -M: Doug Goldstein -M: Stefano Stabellini -W: https://gitlab.com/xen-project/xen -S: Supported -F: .gitlab-ci.yml -F: automation/ - -CPU POOLS -M: Juergen Gross -M: Dario Faggioli -S: Supported -F: xen/common/sched/*cpupool.c - -DEVICE TREE -M: Stefano Stabellini -M: Julien Grall -S: Supported -F: xen/common/libfdt/ -F: xen/common/device_tree.c -F: xen/common/dt-overlay.c -F: xen/include/xen/libfdt/ -F: xen/include/xen/device_tree.h -F: xen/drivers/passthrough/device_tree.c - -ECLAIR -R: Simone Ballarin -S: Supported -F: automation/eclair_analysis/ -F: automation/scripts/eclair - -EFI -M: Jan Beulich -S: Supported -F: xen/arch/x86/efi/ -F: xen/arch/x86/include/asm/efi*.h -F: xen/arch/x86/include/asm/x86_*/efi*.h -F: xen/common/efi/ -F: xen/include/efi/ - -GDBSX DEBUGGER -M: Elena Ufimtseva -S: Supported -F: xen/arch/x86/debug.c -F: tools/debugger/gdbsx/ - -GOLANG BINDINGS -M: George Dunlap -M: Nick Rosbrook -S: Maintained -F: tools/golang - -HYPFS -M: Juergen Gross -S: Supported -F: tools/include/xenhypfs.h -F: tools/libs/hypfs/ -F: tools/misc/xenhypfs.c -F: xen/common/hypfs.c -F: xen/include/xen/hypfs.h - -INTEL(R) TRUSTED EXECUTION TECHNOLOGY (TXT) -R: Lukasz Hawrylko -R: Daniel P.

Xen -is freely-distributable Open Source software, released under the GNU -GPL. Since its initial public release, Xen has grown a large -development community, spearheaded by xen.org (https://www.xen.org). - -This file contains some quick-start instructions to install Xen on -your system. For more information see https://www.xen.org/ and -https://wiki.xen.org/ - -Quick-Start Guide -================= - -First, this is just a quick-start guide. For more comprehensive -information see the INSTALL file and the Xen wiki at -https://wiki.xenproject.org and in particular -https://wiki.xenproject.org/wiki/Getting_Started. - -Second, there are a number of prerequisites for building a Xen source -release. Make sure you have all the following installed, either by -visiting the project webpage or installing a pre-built package -provided by your OS distributor: - * GNU Make v3.80 or later - * C compiler and linker: - - For x86: - - GCC 4.1.2_20070115 or later - - GNU Binutils 2.16.91.0.5 or later - or - - Clang/LLVM 3.5 or later - - For ARM 32-bit: - - GCC 4.9 or later - - GNU Binutils 2.24 or later - - For ARM 64-bit: - - GCC 5.1 or later - - GNU Binutils 2.24 or later - * POSIX compatible awk - * Development install of zlib (e.g., zlib-dev) - * Development install of Python 2.7 or later (e.g., python-dev) - * Development install of curses (e.g., libncurses-dev) - * Development install of openssl (e.g., openssl-dev) - * Development install of x11 (e.g. xorg-x11-dev) - * Development install of uuid (e.g. uuid-dev) - * Development install of yajl (e.g. libyajl-dev) - * Development install of libaio (e.g. libaio-dev) version 0.3.107 or - greater. - * Development install of GLib v2.0 (e.g. libglib2.0-dev) - * Development install of Pixman (e.g. libpixman-1-dev) - * pkg-config - * bridge-utils package (/sbin/brctl) - * iproute package (/sbin/ip) - * GNU bison and GNU flex - * ACPI ASL compiler (iasl) - -In addition to the above there are a number of optional build -prerequisites. Omitting these will cause the related features to be -disabled at compile time: - * Binary-search capable grep (if building Xen with CET support) - * Development install of Ocaml (e.g. ocaml-nox and - ocaml-findlib). Required to build ocaml components which - includes the alternative ocaml xenstored. - * cmake (if building vtpm stub domains) - * pandoc, transfig, pod2{man,html,text} for rendering various pieces of - documentation into alternative formats - * figlet (for generating the traditional Xen start of day banner) - * systemd daemon development files - * Development install of libnl3 (e.g., libnl-3-200, - libnl-3-dev, etc). Required if network buffering is desired - when using Remus with libxl. See docs/README.remus for detailed - information. - * 16-bit x86 assembler, loader and compiler for qemu-traditional / rombios - (dev86 rpm or bin86 & bcc debs) - * Development install of liblzma for rombios - * Development install of libbz2, liblzma, liblzo2, and libzstd for DomU - kernel decompression. - -Second, you need to acquire a suitable kernel for use in domain 0. If -possible you should use a kernel provided by your OS distributor. If -no suitable kernel is available from your OS distributor then refer to -https://wiki.xen.org/wiki/XenDom0Kernels for suggestions for -suitable kernels to use. -If you are looking to compile a Dom0 kernel from source, please refer to -https://wiki.xen.org/wiki/XenParavirtOps. - -[NB. Unless noted otherwise, all the following steps should be -performed with root privileges.] - -1. Download and untar the source tarball file. This will be a - file named xen-unstable-src.tgz, or xen-$version-src.tgz. - You can also pull the current version from the git or mercurial - repositories at https://xenbits.xen.org/ - - # tar xzf xen-unstable-src.tgz - - Assuming you are using the unstable tree, this will - untar into xen-unstable. The rest of the instructions - use the unstable tree as an example, substitute the - version for unstable. - -2. cd to xen-unstable (or whatever you sensibly rename it to). - -3. For the very first build, or if you want to destroy build trees, - perform the following steps: - - # ./configure - # make world - # make install - - See the documentation in the INSTALL file for more info. - - This will create and install onto the local machine. It will build - the xen binary (xen.gz), the tools and the documentation. - - You can override the destination for make install by setting DESTDIR - to some value. - -4. To rebuild an existing tree without modifying the config: - # make dist - - This will build and install xen, tools, and docs into the local dist/ - directory. - - You can override the destination for make install by setting DISTDIR - to some value. - - make install and make dist differ in that make install does the - right things for your local machine (installing the appropriate - version of udev scripts, for example), but make dist includes all - versions of those scripts, so that you can copy the dist directory - to another machine and install from that distribution. - -xenstore: xenstored and oxenstored -==================================== - -Xen uses a configuration database called xenstore [0] to maintain configuration -and status information shared between domains. A daemon is implemented as part -of xenstore to act as an interface for access to the database for dom0 and -guests. Two xenstored daemons are supported, one written in C which we refer -to as the xenstored (sometimes referred to as cxenstored), and another written -in Ocaml called oxenstored. Details for xenstore and the different -implementations can be found on the wiki's xenstore reference guide [1] and -the xenstored [2] page. You can choose which xenstore you want to enable as -default on a system through configure: - - ./configure --with-xenstored=xenstored - ./configure --with-xenstored=oxenstored - -By default oxenstored will be used if the ocaml development tools are found. -If you enable oxenstored the xenstored will still be built and installed, -the xenstored used can be changed through the configuration file: - -/etc/sysconfig/xencommons -or -/etc/default/xencommons - -You can change the preferred xenstored you want to use in the configuration -but since we cannot stop the daemon a reboot will be required to make the -change take effect. - -[0] https://wiki.xen.org/wiki/XenStore -[1] https://wiki.xen.org/wiki/XenStoreReference -[2] https://wiki.xen.org/wiki/Xenstored - -Python Runtime Libraries -======================== - -Various tools, such as pygrub, have the following runtime dependencies: - - * Python 2.7 or later. - URL: https://www.python.org/ - Debian: python - -Intel(R) Trusted Execution Technology Support -============================================= - -Intel's technology for safer computing, Intel(R) Trusted Execution Technology -(Intel(R) TXT), defines platform-level enhancements that provide the building -blocks for creating trusted platforms.

Not all microcode updates (or parts thereof) can be - applied at runtime. - - Given the proprietary nature of microcode, we are unable to make any claim - that runtime microcode loading is risk-free. Any runtime microcode loading - needs adequate testing on a development instance before being rolled out to - production systems. - -The ``xen-ucode`` utility can be used to initiate a runtime microcode load:: - - [root@host ~]# xen-ucode - xen-ucode: Xen microcode updating tool - Usage: xen-ucode - [root@host ~]# - -The details of microcode blobs (if even packaged to begin with) are specific -to the dom0 distribution. Consult your dom0 OS documentation for details. -One example with a Linux dom0 on a Haswell system might look like:: - - [root@host ~]# xen-ucode /lib/firmware/intel-ucode/06-3c-03 - [root@host ~]# - -It will pass the blob to Xen, which will check to see whether the blob is -correct for the processor, and newer than the running microcode. - -If these checks pass, the entire system will be rendezvoused and an update -will be initiated on all CPUs in parallel. As with boot time loading, -diagnostics will be put out onto the console:: - - [root@host ~]# xl dmesg | grep microcode - (XEN) microcode: CPU0 updated from revision 0x1a to 0x25, date = 2018-04-02 - (XEN) microcode: CPU2 updated from revision 0x1a to 0x25, date = 2018-04-02 - (XEN) microcode: CPU4 updated from revision 0x1a to 0x25, date = 2018-04-02 - (XEN) microcode: CPU6 updated from revision 0x1a to 0x25, date = 2018-04-02 - (XEN) 4 cores are to update their microcode - (XEN) microcode: CPU0 updated from revision 0x25 to 0x27, date = 2019-02-26 - (XEN) microcode: CPU4 updated from revision 0x25 to 0x27, date = 2019-02-26 - (XEN) microcode: CPU2 updated from revision 0x25 to 0x27, date = 2019-02-26 - (XEN) microcode: CPU6 updated from revision 0x25 to 0x27, date = 2019-02-26 diff --git a/src/xen/docs/admin-guide/xen-overview.drawio.svg b/src/xen/docs/admin-guide/xen-overview.drawio.svg deleted file mode 100644 index f120cdf..0000000 --- a/src/xen/docs/admin-guide/xen-overview.drawio.svg +++ /dev/null @@ -1,97 +0,0 @@ - - - - - - - - Xen - - - - Dom0 - - - - DomU - - - - DomU - - - - Hardware - - - - NIC - - - - Disk - - - - Systems Services - - - - Applications - - - - Applications - - - - Kernel - - - - Net - - - - Block - - - - Kernel - - - - Kernel - - - - Net - - - - Block - - - - Net - - - - Block - - - - - - - - - - - - - - - - - diff --git a/src/xen/docs/conf.py b/src/xen/docs/conf.py deleted file mode 100644 index 50e4150..0000000 --- a/src/xen/docs/conf.py +++ /dev/null @@ -1,194 +0,0 @@ -# -*- coding: utf-8 -*- -# SPDX-License-Identifier: CC-BY-4.0 -# -# Configuration file for the Sphinx documentation builder. -# -# This file does only contain a selection of the most common options.

It provides Xen hypervisor -primitives to transmit data between VMs, by performing data copies into -receive memory rings registered by domains. It does not require memory -sharing between VMs and does not use the grant tables or Xenstore. - -Argo has requirements for performance isolation between domains, to prevent -negative performance impact from malicious or disruptive activity of other -domains, or even other VCPUs of the same domain operating other rings. - -## Hypervisor-Mediated data eXchange (HMX) - -This term references inter-VM communication protocols that have this -key architectural point: The hypervisor is responsible for performing the -write of data into the guest-accessible memory buffer, in the manner -according to the agreed transfer protocol. This structure ensures that -there is strength to the transport mechanism, because the transmitting side -of the communication is the hypervisor, which can be trusted by the receiver, -and the buffer is isolated from access by any other potential sources -outside the receiver. - -The receiver can trust that the hypervisor will: - -- Provide a protocol implementation adhering to hardware synchronization -requirements for concurrent access to system memory by communicating -components -- Deliver data only from an approved source, enforcing policy for Mandatory -Access Control. -- Indicate the correct sender of the data. -- Transmit only the intended data, adhering to the access protocol of the data -structure in the buffer. If the memory region is being used as a ring, then: - - Data writes will only occur within the ring region that is indicated as - available for incoming data by the ring indexes. - - The indicated length of data written will exactly match the length of - data actually written. - - The write for each piece of data will occur only once. - - Data will be written sequentially in the order that it is sent. -- Issue notification of data delivered correctly. - -This structure allows for augmentation by the hypervisor to identify the -sending entity within the source VM, and then provide the receiver with -assured context information about the data source. This enables the receiver -to make decisions based on fine-grained knowledge of the source of the data. - -This structure is also of strong interest for nested virtualization: -transport via the hypervisor can enable construction of efficient -communications between VMs at different levels of nesting. - -# Locking - -Since Argo operates a data path between domains, sections of this code are -*hot* when the communication paths are in use. To encourage high performance, a -goal is to limit mutual exclusion to only where required and enable significant -concurrency. - -Avoidance of deadlock is essential and since state must frequently be updated -that pertains to more than one domain, a locking protocol defines which locks -are needed and the order of their acquistion. - -## Structure - -The granular locking structure of Argo enables: - -1. Performance isolation of guests -2. Avoidance of DoS of rings by domains that are not authorized to send to them -3. Deadlock-free teardown of state across multiple domains on domain destroy -4. Performance of guests using Argo with concurrent operation of rings. - -Argo uses three per-domain locks to protect three separate data structures. -Access to the ring_hash data structure is confined to domains that a -ring-registering domain has authorized to send data via the ring. The complete -set of Argo locks is: - -* Global : `L1_global_argo_rwlock` -* Per-domain: `rings_L2_rwlock` -* Per-domain: `send_L2_lock` -* Per-domain: `wildcard_L2_lock` -* Per-ring: `L3_lock` - -## Protected State - -The data structures being protected by the locks are all per-domain. The only -global Argo state is the `L1_global_argo_rwlock` used to coordinate access to -data structures of other domains. - -### State: Rings registered and owned by a domain - -This includes the state to run that ring, such as memory frame numbers and -established mappings. Per-ring state is protected by its own lock, so that -multiple VCPUs of the same domain operating different rings do not inhibit the -performance of each other. - -The per-domain ring state also includes the list of pending notifications for -other domains that are waiting for ring space availability. - -### State: Partner rings for which this domain is the single allowed sender - -This state belonging to the permitted sender is written to when a ring is -registered by another domain. The lock that protects this state is subject to -locking at arbitrary frequency by those foreign domains when registering rings --- which do not need any permission granted by this domain in order to register -a ring to communicate with it -- so it must not inhibit the domain's own -ability to use its own rings, to protect them from DoS. For this reason, this -state is protected by its own lock. - -### State: Pending notifications for wildcard rings registered by other domains - -This data structure is needed when a domain is destroyed, to cancel the -outstanding space availability notifications about the wildcard rings of other -domains that this domain has queried. - -Data is entered into this data structure by the domain that owns it, either by -a space-inhibited sendv or a notify operation. - -Data is removed from this data structure in one of three cases: when space -becomes available in the destination ring and the notification is sent, when -the ring is torn down, or when the awaiting domain is destroyed. - -In the case where a notification is sent, access to the data structure is -triggered by the ring owner domain, rather than the domain waiting for -notification. This data structure is protected by its own lock since doing so -entails less contention than the alternative of reusing an existing lock owned -by the domain. - -## Hierarchical Locking Model and Protocol - -The locking discipline within the Argo code is heirarchical and utilizes -reader/writer locks to enable increased concurrency when operations do not -conflict. None of the Argo locks are reentrant. - -The hierarchy: - -* There is a global rwlock (`L1`) to protect access to all of the per-domain -argo data structures. -* There is a rwlock per-domain (`rings_L2`) to protect the hashtable of the -per-ring data structures. -* There is a lock per ring (`L3`) to protect the per-ring data structure, -`struct argo_ring_info`. - -There are a two other per-domain L2 locks; their operation is similar and they -are described later. - -The protocol to safely acquire write access to the per-ring data structure, -`struct argo_ring_info`, is: - -1) Acquire a Read lock on L1. -2) Acquire a Read lock on L2. -3) Acquire L3. - -An alternative valid sequence is: - -1) Acquire a Read lock on L1. -2) Acquire a Write lock on L2. - -This second sequence grants write access to _all_ of the `argo_ring_info` -structs belonging to the domain, but at the expense of less concurrency: no -other operation can access those structs while the locks are held, which will -inhibit operations on those rings until the locks are released. - -Another alternative valid sequence is: - -1) Acquire a Write lock on L1. - -This grants write access to _all_ of the `argo_ring_info` structs belonging to -_all domains_, but again at the expense of far less concurrency: no other -operation can operate on Argo rings until the locks are released. - -## Lock Definitions - -The full set of locks that are directly operated upon by the Argo code are -described in the following section. - -### The global singleton lock: - -* `L1_global_argo_rwlock` - -The rationale for having a global lock is to be able to enforce system-wide -exclusion for a critical region and simplify the logic required to avoid -deadlock, for teardown of state across multiple domains when a domain is -destroyed. - -The majority of operations take a read-lock on this lock, allowing concurrent -Argo operations by many domains. - -The pointer d->argo on every domain is protected by this lock. A set of more -granular per-domain locks could be used to do that, but since domain start and -stop is expected to be a far less frequent operation than the other argo -operations, acquiring a single read lock to enable access to all the argo -structs of all domains simplifies the protocol. - -Points of write-locking on this lock: - -* `argo_destroy`, where: - * All of the domain's own rings are destroyed. - * All of the notifications pending for other domains are cancelled. - * All of the unicast partner rings owned by other domains for this domain to -send to, are destroyed. - * All of the notifications pending on those rings are cancelled. - * All of the notifications pending for this domain on wildcard rings owned -by other domains are cancelled. -* `argo_soft_reset`, for similar teardown operations as argo_destroy. -* `argo_init`, where the `d->argo` pointer is first populated. - * Since the write lock is taken here, there is serialization all concurrent -Argo operations around this single pointer write; this is the cost of using the -simpler one global lock approach. - -Enforcing that the write_lock is acquired on `L1_global_argo_rwlock` before -executing teardown, ensures that no teardown operations act concurrently and no -other Argo operations happen concurrently with a teardown. The teardown logic -is free to safely modify the Argo state across all domains without having to -acquire per-domain locks and deadlock cannot occur. - -### Per-Domain: Ring hash lock - -`rings_L2_rwlock` - -Protects: the per-domain ring hash table of `argo_ring_info` structs. - -Holding a read lock on `rings_L2` protects the ring hash table and the elements -in the hash table `d->argo->ring_hash`, and the `node` and `id` fields in -struct `argo_ring_info` in the hash table. - -Holding a write lock on `rings_L2` protects all of the elements of all the -struct `argo_ring_info` belonging to this domain. - -To take `rings_L2` you must already have `R(L1)`. `W(L1)` implies `W(rings_L2)` -and `L3`. - -Prerequisites: - -* `R(L1_global_argo_rwlock)` must be acquired before taking either read or -write on `rings_L2_rwlock`. -* `W(L1_global_argo_rwlock)` implies `W(rings_L2_rwlock)`, so if -`W(L1_global_argo_rwlock)` is held, then `rings_L2_rwlock` does not need to be -acquired, and all the data structures that `rings_L2_rwlock` protects can be -accessed as if `W(ring_L2_rwlock)` was held. - -Is accessed by the hypervisor on behalf of: - -* The domain that registered the ring. -* Any domain that is allowed to send to the ring -- so that's the partner -domain, for unicast rings, or any domain, for wildcard rings. - -### Send hash lock - -`send_L2_lock` - -Protects: the per-domain send hash table of `argo_send_info` structs. - -Is accessed by the hypervisor on behalf of: - -* Any domain that registers a ring that specifies the domain as the unicast -sender. -* The domain that has been allowed to send, as part of teardown when the domain -is being destroyed. - - -### Wildcard pending list lock - -`wildcard_L2_lock` - -Protects: the per-domain list of pending notifications to the domain from -wildcard rings owned by other domains. - -Is accessed by the hypervisor on behalf of: - -* The domain that issued a query to another about space availability in one of -its wildcard rings - this can be done by attempting a send operation when there -is insufficient ring space available at the time. -* Any domain that the domain has issued a query to about space availability in -one of their wildcard rings. - -### Per-Ring locks: - -* `L3_lock` - -This lock protects the members of a `struct ring_info` which is the primary -state for a domain's own registered ring. - - -## Reasoning Model - -A common model for reasoning about concurrent code focusses on accesses to -individual variables: if code touches this variable, see that it first acquires -the corresponding lock and then drops it afterwards. A challenge with this -model is in ensuring that the sequence of locks acquired within nested -functions, when operating on data from multiple domains with concurrent -operations, is safe from deadlock. - -An alternative method that is better suited to the Argo software is to consider -the execution path, the full sequence of locks acquired, accesses performed, -and locks released, from entering an operation, to the completion of the work. - -An example code path for an operation: - -`[entry] > -- [ take R(L1) ] -- [ take R(L2) ] -- loop [ take a L3 / drop L3 ] --- [ drop R(L2) ] -- [ drop R(L1)] -- > [exit]` - -If a function implements a section of the path, it is important to know not -only what variables the function itself operates upon, but also the locking -state that will already have been established at the point when the function is -invoked, since this will affect what data the function can access. For this -reason, comments in the code, or ASSERTs that explicitly check lock state, -communicate what the locking state is expected and intended to be when that -code is invoked. See the macros defined to support this for Argo later in this -document. - - -## Macros to Validate and Document Lock State - -These macros encode the logic to verify that the locking has adhered to the -locking discipline. - -eg. On entry to logic that requires holding at least `R(rings_L2)`, this: - -`ASSERT(LOCKING_Read_rings_L2(d));` - -checks that the lock state is sufficient, validating that one of the following -must be true when executed: - -`R(rings_L2) && R(L1)` -or: `W(rings_L2) && R(L1)` -or: `W(L1)` - -The macros are defined thus: - -``` -#define LOCKING_Write_L1 (rw_is_write_locked(&L1_global_argo_rwlock)) -/* - * While LOCKING_Read_L1 will return true even if the lock is write-locked, - * that's OK because everywhere that a Read lock is needed with these macros, - * holding a Write lock there instead is OK too: we're checking that _at least_ - * the specified level of locks are held. - */ -#define LOCKING_Read_L1 (rw_is_locked(&L1_global_argo_rwlock)) - -#define LOCKING_Write_rings_L2(d) \ - ((LOCKING_Read_L1 && rw_is_write_locked(&(d)->argo->rings_L2_rwlock)) || \ - LOCKING_Write_L1) -/* - * Skip checking LOCKING_Write_rings_L2(d) within this LOCKING_Read_rings_L2 - * definition because the first clause that is testing R(L1) && R(L2) will also - * return true if R(L1) && W(L2) is true, because of the way that rw_is_locked - * behaves. This results in a slightly shorter and faster implementation. - */ -#define LOCKING_Read_rings_L2(d) \ - ((LOCKING_Read_L1 && rw_is_locked(&(d)->argo->rings_L2_rwlock)) || \ - LOCKING_Write_L1) -/* - * Skip checking LOCKING_Write_L1 within this LOCKING_L3 definition because - * LOCKING_Write_rings_L2(d) will return true for that condition. - */ -#define LOCKING_L3(d, r) \ - ((LOCKING_Read_L1 && rw_is_locked(&(d)->argo->rings_L2_rwlock) \ - && spin_is_locked(&(r)->L3_lock)) || LOCKING_Write_rings_L2(d)) - -#define LOCKING_send_L2(d) \ - ((LOCKING_Read_L1 && spin_is_locked(&(d)->argo->send_L2_lock)) || \ - LOCKING_Write_L1) -``` - -Here is an example of a macro in use: - -``` -static void -notify_ring(const struct domain *d, struct argo_ring_info *ring_info, - struct hlist_head *to_notify) -{ - uint32_t space; - - ASSERT(LOCKING_Read_rings_L2(d)); - - spin_lock(&ring_info->L3_lock); - - if ( ring_info->len ) - space = ringbuf_payload_space(d, ring_info); - else - space = 0; - - spin_unlock(&ring_info->L3_lock); - - if ( space ) - pending_find(d, ring_info, space, to_notify); -} - -``` - -In the above example, it can be seen that it is safe to acquire the `L3` lock -because _at least_ `R(rings_L2)` is already held, as documented and verified by -the macro. - -## FAQ / Other Considerations - -### Why not have a single per-domain lock? - -Due to performance isolation / DoS avoidance: if there is a single per-domain -lock, acquiring this lock will stall operations on other active rings owned by -the domain. A malicious domain can loop registering and unregistering rings, -without any consent by the targetted domain, which would experience decreased -throughput due to the contention on the single per-domain lock. The granular -locking structure of Argo prevents this. It also allows concurrent operation of -different rings by multiple VCPUs of the same domain without contention, to -avoid negative application performance interaction. - -## Rationale for Using a Singleton Global Lock: L1 - -### Teardown on domain destroy - -The single global lock enables exclusive access to the argo data structures -across domains when a domain is destroyed. Every unicast ring that the dying -domain is the authorized sender is torn down and any pending space-available -notifications in other domain's wildcard rings are cancelled. This requires -gaining safe access to the data structures on each of the domains involved. - -The 'send hashtable' data structure is needed in order to perform the teardown -of rings when a domain is destroyed. To populate it, whenever a unicast ring is -registered, the lock that protects that data structure must be taken -exclusively. - -There are granular per-domain locks which protect the per-domain data -structures. The global singleton L1 lock operates with-and-above the per-domain -locks and is used to obtain exclusive access to multiple domain's argo data -structures in the infrequent case where it is used -- for domain destroy -- -whilst otherwise allowing concurrent access, via acquiring it with 'read' -access, for the majority of the time. - -To perform the required state teardown on domain destruction, which can require -removing state from the data structures of multiple domains, a locking protocol -to obtain mutual exclusion and safe access to the state is required, without -deadlocking. - -Using the single global lock avoids the need for sequencing the acquisition of -multiple individual per-domain locks (and lower level data structure locks) to -prevent deadlock: taking W(L1) grants access to all and taking R(L1) ensures -that teardown of any domain will not interfere with any Argo hypercall -operation.

First, the ABI is fully stable, to reduce the coupling between -device models and the version of Xen. Specifically, device model software -using DMOP (be it user, stub domain or kernel software) need not be recompiled -to match the version of the running hypervisor. - -Secondly, for device models in userspace, the ABI is designed specifically to -allow a kernel to audit the memory ranges used, without having to know the -internal structure of sub-ops. - -The problem occurs when you a device model issues an hypercall that -includes references to user memory other than the operation structure -itself, such as with Track dirty VRAM (as used in VGA emulation). -Is this case, the address of this other user memory needs to be vetted, -to ensure it is not within restricted address ranges, such as kernel -memory. The real problem comes down to how you would vet this address - -the idea place to do this is within the privcmd driver, without privcmd -having to have specific knowledge of the hypercall's semantics. - -The Design ----------- - -The privcmd driver implements a new restriction ioctl, which takes a domid -parameter. After that restriction ioctl is issued, all unaudited operations -on the privcmd driver will cease to function, including regular hypercalls. -DMOP hypercalls will continue to function as they can be audited. - -A DMOP hypercall consists of a domid (which is audited to verify that it -matches any restriction in place) and an array of buffers and lengths, -with the first one containing the specific DMOP parameters.

If they are needed, they should instead be in -HYPERVISOR_dm_op->bufs. - -Validation by privcmd driver ----------------------------- - -If the privcmd driver has been restricted to specific domain (using a - new ioctl), when it received an op, it will: - -1.

This is for cases where some preprocessing in a less privileged domain - is required before starting the all-privileged Domain 0. - -Hyperlaunch Classic: Basic Cloud - This configuration constructs a Dom0 that is started in parallel with some - number of workload domains. - -Hyperlaunch Classic: Cloud - This configuration builds a Dom0 and some number of workload domains, launched - via a Boot Domain that runs first. - - -Static Launch Configurations: without a Domain 0 or a Control Domain -^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ - -Hyperlaunch Static: Basic - Simple static partitioning where all domains that can be run on this system are - built and started during host boot and where no domain is started with the - Control Domain permissions, thus making it not possible to create/start any - further new domains. - -Hyperlaunch Static: Standard - This is a variation of the “Hyperlaunch Static: Basic†static partitioning - configuration with the introduction of a Boot Domain. This configuration allows - for use of a Boot Domain to be able to apply extended configuration - to the Initial Domains before they are started and - sequence the order in which they start. - -Hyperlaunch Static: Disaggregated - This is a variation of the “Hyperlaunch Static: Standard†configuration with - the introduction of a Boot Domain and an illustration that some functions can - be disaggregated to dedicated domains. - -Dynamic Launch of Disaggregated System Configurations -^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ - -Hyperlaunch Dynamic: Hardware Domain - This configuration mimics the existing Xen feature late hardware domain with - the one difference being that the hardware domain is constructed by the - hypervisor at startup instead of later by Dom0. - -Hyperlaunch Dynamic: Flexible Disaggregation - This configuration is similar to the “Hyperlaunch Classic: Dom0†configuration - except that it includes starting a separate hardware domain during Xen startup. - It is also similar to “Hyperlaunch Dynamic: Hardware Domain†configuration, but - it launches via a Boot Domain that runs first. - -Hyperlaunch Dynamic: Full Disaggregation - In this configuration it is demonstrated how it is possible to start a fully - disaggregated system: the virtualization toolstack runs in a Control Domain, - separate from the domains responsible for managing hardware, XenStore, the Xen - Console and Crash functions, each launched via a Boot Domain. - - -Example Use Cases and Configurations -^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ - -The following example use cases can be matched to configurations listed in the -previous section. - -Use case: Modern cloud hypervisor -""""""""""""""""""""""""""""""""" - -**Option:** Hyperlaunch Classic: Cloud - -This configuration will support strong isolation for virtual TPM domains and -measured launch in support of attestation to infrastructure management, while -allowing the use of existing Dom0 virtualization toolstack software. - -Use case: Edge device with security or safety requirements -"""""""""""""""""""""""""""""""""""""""""""""""""""""""""" - -**Option:** Hyperlaunch Static: Boot - -This configuration runs without requiring a highly-privileged Dom0, and enables -extended VM configuration to be applied to the Initial VMs prior to launching -them, optionally in a sequenced start. - -Use case: Client hypervisor -""""""""""""""""""""""""""" - -**Option:** Hyperlaunch Dynamic: Flexible Disaggregation - -**Option:** Hyperlaunch Dynamic: Full Disaggregation - -These configurations enable dynamic client workloads, strong isolation for the -domain running the virtualization toolstack software and each domain managing -hardware, with PCI passthrough performed during host boot and support for -measured launch. - -Hyperlaunch Disaggregated Launch --------------------------------- - - -Existing in Xen today are two primary permissions, *control domain* and -*hardware domain*, and two functions, *console domain* and *xenstore domain*, -that can be assigned to a domain. Traditionally all of these permissions and -functions are all assigned to Dom0 at start and can then be delegated to other -domains created by the toolstack in Dom0. With Hyperlaunch it becomes possible -to assign these permissions and functions to any domain for which there is a -definition provided at startup. - -Additionally, two further functions are introduced: the *recovery domain*, -intended to assist with recovery from failures encountered starting VMs during -host boot, and the *boot domain*, for performing aspects of domain construction -during startup. - -Supporting the booting of each of the above common boot configurations is -accomplished by considering the set of initial domains and the assignment of -Xen’s permissions and functions, including the ones introduced by Hyperlaunch, -to these domains. A discussion of these will be covered later but for now they -are laid out in a table with a mapping to the common boot configurations. This -table is not intended to be an exhaustive list of configurations and does not -account for flask policy specified functions that are use case specific. - -In the table each number represents a separate domain being -constructed by the Hyperlaunch construction path as Xen starts, and the -designator, ``{n}`` signifies that there may be “n†additional domains that may -be constructed that do not have any special role for a general Xen system. - -:: - - +-------------------+------------------+-----------------------------------+ - | Configuration | Permission | Function | - | +------+------+----+------+--------+--------+----------+ - | | None | Ctrl | HW | Boot |Recovery| Console| Xenstore | - +===================+======+======+====+======+========+========+==========+ - | Classic: Dom0 | | 0 | 0 | | 0 | 0 | 0 | - +-------------------+------+------+----+------+--------+--------+----------+ - | Classic: Extended | | 1 | 1 | 0 | 1 | 1 | 1 | - | Launch Dom0 | | | | | | | | - +-------------------+------+------+----+------+--------+--------+----------+ - | Classic: | {n} | 0 | 0 | | 0 | 0 | 0 | - | Basic Cloud | | | | | | | | - +-------------------+------+------+----+------+--------+--------+----------+ - | Classic: Cloud | {n} | 1 | 1 | 0 | 1 | 1 | 1 | - +-------------------+------+------+----+------+--------+--------+----------+ - | Static: Basic | {n} | | 0 | | 0 | 0 | 0 | - +-------------------+------+------+----+------+--------+--------+----------+ - | Static: Standard | {n} | | 1 | 0 | 1 | 1 | 1 | - +-------------------+------+------+----+------+--------+--------+----------+ - | Static: | {n} | | 2 | 0 | 3 | 4 | 1 | - | Disaggregated | | | | | | | | - +-------------------+------+------+----+------+--------+--------+----------+ - | Dynamic: | | 0 | 1 | | 0 | 0 | 0 | - | Hardware Domain | | | | | | | | - +-------------------+------+------+----+------+--------+--------+----------+ - | Dynamic: Flexible | {n} | 1 | 2 | 0 | 1 | 1 | 1 | - | Disaggregation | | | | | | | | - +-------------------+------+------+----+------+--------+--------+----------+ - | Dynamic: Full | {n} | 2 | 3 | 0 | 4 | 5 | 1 | - | Disaggregation | | | | | | | | - +-------------------+------+------+----+------+--------+--------+----------+ - -Overview of Hyperlaunch Flow ----------------------------- - -Before delving into Hyperlaunch, a good basis to start with is an understanding -of the current process to create a domain. A way to view this process starts -with the core configuration which is the information the hypervisor requires to -make the call to `domain_create`, followed by basic construction to provide the -memory image to run, including the kernel and ramdisk. A subsequent step -applies the extended configuration used by the toolstack to provide a domain -with any additional configuration information. Until the extended configuration -is completed, a domain has access to no resources except its allocated vcpus -and memory. The exception to this is Dom0, which the hypervisor explicitly -grants control and access to all system resources, except for those that only -the hypervisor should have control over. This exception for Dom0 is driven by -the system structure with a monolithic Dom0 domain predating introduction of -support for disaggregation into Xen, and the corresponding default assignment -of multiple roles within the Xen system to Dom0. - -While not a different domain creation path, there does exist the Hardware -Domain (hwdom), sometimes also referred to as late-Dom0. It is an early effort -to disaggregate Dom0’s roles into a separate control domain and hardware -domain. This capability is activated by the passing of a domain id to the -`hardware_dom` kernel command line parameter, and the Xen hypervisor will then -flag that domain id as the hardware domain. Later when the toolstack constructs -a domain with that domain id as the requested domid, the hypervisor will -transfer all device I/O from Dom0 to this domain. In addition it will also -transfer the “host shutdown on domain shutdown†flag from Dom0 to the hardware -domain. It is worth mentioning that this approach for disaggregation was -created in this manner due to the inability of Xen to launch more than one -domain at startup. - -Hyperlaunch Xen startup -^^^^^^^^^^^^^^^^^^^^^^^ - -The Hyperlaunch approach’s primary focus is on how to assign the roles -traditionally granted to Dom0 to one or more domains at host boot. While the -statement is simple to make, the implications are not trivial by any means. -This also explains why the Hyperlaunch approach is orthogonal to the existing -dom0less capability. The dom0less capability focuses on enabling the launch of -multiple domains in parallel with Dom0 at host boot. A corollary for dom0less -is that for systems that don’t require Dom0 after all guest domains have -started, they are able to do the host boot without a Dom0. Though it should be -noted that it may be possible to start Dom0 at a later point. Whereas with -Hyperlaunch, its approach of separating Dom0’s roles requires the ability to -launch multiple domains at host boot. The direct consequences from this -approach are profound and provide a myriad of possible configurations for which -a sample of common boot configurations were already presented. - -To enable the Hyperlaunch approach a new alternative path for host boot within -the hypervisor must be introduced. This alternative path effectively branches -just before the current point of Dom0 construction and begins an alternate -means of system construction. The determination if this alternate path should -be taken is through the inspection of the boot chain. If the bootloader has -loaded a specific configuration, as described later, it will enable Xen to -detect that a Hyperlaunch configuration has been provided. Once a Hyperlaunch -configuration is detected, this alternate path can be thought of as occurring -in phases: domain creation, domain preparation, and launch finalization. - -Domain Creation -""""""""""""""" - -The domain creation phase begins with Xen parsing the bootloader provided -material, to understand the content of the modules provided. It will then load -any microcode or XSM policy it discovers. For each domain configuration Xen -finds, it parses the configuration to construct the necessary domain definition -to instantiate an instance of the domain and leave it in a paused state. When -all domain configurations have been instantiated as domains, if one of them is -flagged as the Boot Domain, that domain will be unpaused starting the domain -preparation phase. If there is no Boot Domain defined, then the domain -preparation phase will be skipped and Xen will trigger the launch finalization -phase. - -Domain Preparation Phase -"""""""""""""""""""""""" - -The domain preparation phase is an optional check point for the execution of a -workload specific domain, the Boot Domain. While the Boot Domain is the first -domain to run and has some degree of control over the system, it is extremely -restricted in both system resource access and hypervisor operations. Its -purpose is to: - -* Access the configuration provided by the bootloader -* Finalize the configuration of the domains -* Conduct any setup and launch related operations -* Do an ordered unpause of domains that require an ordered start - -When the Boot Domain has completed, it will notify the hypervisor that it is -done triggering the launch finalization phase. - - -Launch Finalization -""""""""""""""""""" - -The hypervisor handles the launch finalization phase which is equivalent to the -clean up phase. As such the steps taken by the hypervisor, not necessarily in -implementation order, are as follows, - -* Free the boot module chain -* If a Boot Domain was used, reclaim Boot Domain resources -* Unpause any domains still in a paused state -* Boot Domain uses a reserved function thus can never be respawned - -While the focus thus far has been on how the Hyperlaunch capability will work, -it is worth mentioning what it does not do or limit from occurring. It does not -stop or inhibit the assigning of the control domain role which gives the domain -the ability to create, start, stop, restart, and destroy domains or the -hardware domain role which gives access to all I/O devices except those that -the hypervisor has reserved for itself. In particular it is still possible to -construct a domain with all the privileged roles, i.e. a Dom0, with or without -the domain id being zero. In fact what limitations are imposed now become fully -configurable without the risk of circumvention by an all privileged domain. - -Structuring of Hyperlaunch --------------------------- - -The structure of Hyperlaunch is built around the existing capabilities of the -host boot protocol. This approach was driven by the objective not to require -modifications to the boot loader. The only requirement is that the boot loader -supports the Multiboot2 (MB2) protocol. For UEFI boot, our recommendation is to -use GRUB.efi to load Xen and the initial domain materials via the multiboot2 -method. On Arm platforms, Hyperlaunch is compatible with the existing interface -for boot into the hypervisor. - - -x86 Multiboot2 -^^^^^^^^^^^^^^ - -The MB2 protocol has no concept of a manifest to tell the initial kernel what -is contained in the chain, leaving it to the kernel to impose a loading -convention, use magic number identification, or both. When considering the -passing of multiple kernels, ramdisks, and domain configuration along with any -existing modules already passed, there is no sane convention that could be -imposed and magic number identification is nearly impossible when considering -the objective not to impose unnecessary complication to the hypervisor. - -As it was alluded to previously, a manifest describing the contents in the MB2 -chain and how they relate within a Xen context is needed. To address this need -the Launch Control Module (LCM) was designed to provide such a manifest. The -LCM was designed to have a specific set of properties, - -* minimize the complexity of the parsing logic required by the hypervisor -* allow for expanding and optional configuration fragments without breaking - backwards compatibility - -To enable automatic detection of a Hyperlaunch configuration, the LCM must be -the first MB2 module in the MB2 module chain. The LCM is implemented using the -Device Tree as defined in the Hyperlaunch Device Tree design document. With the -LCM implemented in Device Tree, it has a magic number that enables the -hypervisor to detect its presence when used in a Multiboot2 module chain. The -hypervisor can confirm that it is a proper LCM Device Tree by checking for a -compliant Hyperlaunch Device Tree. The Hyperlaunch Device Tree nodes are -designed to allow, - -* for the hypervisor to parse only those entries it understands, -* for packing custom information for a custom boot domain, -* the ability to use a new LCM with an older hypervisor, -* and the ability to use an older LCM with a new hypervisor. - -Arm Device Tree -^^^^^^^^^^^^^^^ - -As discussed the LCM is in Device Tree format and was designed to co-exist in -the Device Tree ecosystem, and in particular in parallel with dom0less Device -Tree entries. On Arm, Xen is already designed to boot from a host Device Tree -description (dtb) file and the LCM entries can be embedded into this host dtb -file. This makes detecting the LCM entries and supporting Hyperlaunch on Arm -relatively straight forward. Relative to the described x86 approach, at the -point where Xen inspects the first MB2 module, on Arm Xen will check if the top -level LCM node exists in the host dtb file. If the LCM node does exist, then at -that point it will enter into the same code path as the x86 entry would go. - -Xen hypervisor -^^^^^^^^^^^^^^ - -It was previously discussed at a higher level of the new host boot flow that -will be introduced. Within this new flow is the configuration parsing and -domain creation phase which will be expanded upon here. The hypervisor will -inspect the LCM for a config node and if found will iterate through all modules -nodes. The module nodes are used to identify if any modules contain microcode -or an XSM policy. As it processes domain nodes, it will construct the domain -using the node properties and the modules nodes. Once it has completed -iterating through all the entries in the LCM, if a constructed domain has the -Boot Domain attribute, it will then be unpaused. Otherwise the hypervisor will -start the launch finalization phase. - -Boot Domain -^^^^^^^^^^^ - -Traditionally domain creation was controlled by the user within the Dom0 -environment whereby custom toolstacks could be implemented to impose -requirements on the process. The Boot Domain is a means to enable the user to -continue to maintain a degree of that control over domain creation but within a -limited privilege environment. The Boot Domain will have access to the LCM and -the boot chain along with access to a subset of the hypercall operations. When -the Boot Domain is finished it will notify the hypervisor through a hypercall -op. - -Recovery Domain -^^^^^^^^^^^^^^^ - -With the existing Dom0 host boot path, when a failure occurs there are several -assumptions that can safely be made to get the user to a console for -troubleshooting. With the Hyperlaunch host boot path those assumptions can no -longer be made, thus a means is needed to get the user to a console in the case -of a recoverable failure. The recovery domain is configured by a domain -configuration entry in the LCM, in the same manner as the other initial -domains, and it will not be unpaused at launch finalization unless a failure is -encountered starting the initial domains. - -Xen has existing support for a Crash Environment where memory can be reserved -at host boot and a kernel loaded into it, to be jumped into at any point while -the system is running when a crash is detected. The Recovery Domain -functionality is a separate, complementary capability. The Crash Environment -replaces the previously active hypervisor and running guests, and enables a -process for mounting disks to write out log information prior to rebooting the -system. In contrast, the Recovery Domain is able to use the functionality of -the Xen hypervisor, that is still present and running, to perform recovery -handling for errors encountered with starting the initial domains. - -Deferred Design -""""""""""""""" - -To be determined: - -* Define what is detected as a crash -* Explain how crash detection is performed and which components are involved -* Explain how the recovery domain is unpaused -* Explain how and when the resources assigned to the recovery domain are reclaimed -* Define what the recovery domain is able to do -* Determine what permissions the recovery domain requires to perform its job - - -Control Domain -^^^^^^^^^^^^^^ - -The concept of the Control Domain already exists within Xen as a boolean, -`is_privileged`, that governs access to many of the privileged interfaces of -the hypervisor that support a domain running a virtualization system toolstack. -Hyperlaunch will allow the `is_privileged` flag to be set on any domain that is -created at launch, rather than only a Dom0. It may potentially be set on -multiple domains. - -Hardware Domain -^^^^^^^^^^^^^^^ - -The Hardware Domain is also an existing concept for Xen that is enabled through -the `is_hardware_domain` check. With Hyperlaunch the previous process of I/O -accesses being assigned to Dom0 for later transfer to the hardware domain would -no longer be required. Instead during the configuration phase the Xen -hypervisor would directly assign the I/O accesses to the domain with the -hardware domain permission bit enabled. - -Console Domain -^^^^^^^^^^^^^^ - -Traditionally the Xen console is assigned to the control domain and then -reassignable by the toolstack to another domain. With Hyperlaunch it becomes -possible to construct a boot configuration where there is no control domain or -have a use case where the Xen console needs to be isolated. As such it becomes -necessary to be able to designate which of the initial domains should be -assigned the Xen console. Therefore Hyperlaunch introduces the ability to -specify an initial domain which the console is assigned along with a convention -of ordered assignment for when there is no explicit assignment. - -Communication of Domain Configurations -====================================== - -There are several standard methods for an Operating System to access machine -configuration and environment information: ACPI is common on x86 systems, -whereas Device Tree is more typical on Arm platforms. There are currently -implementations of both in Xen. - -* For dom0less, guest Device Trees are dynamically constructed by the - hypervisor to convey domain configuration data - -* For PVH dom0 on x86, ACPI tables are built by the hypervisor before the - domain is started - -Note that both of these mechanisms convey static data that is fixed prior to -the point of domain construction. Hyperlaunch will retain both the existing -ACPI and Device Tree methods. - -Communication of data between a Boot Domain and a Control Domain is of note -since they may not be running concurrently: the method used will depend on -their specific implementations, but one option available is to use Xen’s hypfs -for transfer of basic data to support system bootstrap. - -------------------------------------------------------------------------------- - -Appendix -======== - -Appendix 1: Flow Sequence of Steps of a Hyperlaunch Boot --------------------------------------------------------- - -Provided here is an ordered flow of a Hyperlaunch with a highlight logic -decision points.

This model dates from -an era when it was assumed that the host administrator had control of at -least the privileged software running in the guest (i.e. the guest kernel) -which may still be true in an enterprise deployment but is not generally -true in a cloud environment. The aim of this design is to provide a model -which is purely host driven, requiring no co-operation from the software -running in the guest, and is thus suitable for cloud scenarios. - -PV guests are out of scope for this project because, as is outlined above, -they have a symbiotic relationship with the hypervisor and therefore a -certain level of co-operation is required. - -x86 HVM guests can already be migrated on Xen without guest co-operation -but only if they don’t have PV drivers installed[1] or are not in ACPI -power state S0. The reason for not expecting co-operation if the guest is -any sort of suspended state is obvious, but the reason co-operation is -expected if PV drivers are installed is due to the nature of PV protocols. - -## Xenstore Nodes and Domain ID - -The PV driver model consists of a *frontend* and a *backend*. The frontend -runs inside the guest domain and the backend runs inside a *service domain* -which may or may not be domain 0. The frontend and backend typically pass -data via memory pages which are shared between the two domains, but this -channel of communication is generally established using xenstore (the store -protocol itself being an exception to this for obvious chicken-and-egg -reasons). - -Typical protocol establishment is based on use of two separate xenstore -*areas*. If we consider PV drivers for the *netif* protocol (i.e. class vif) -and assume the guest has domid X, the service domain has domid Y, and the -vif has index Z then the frontend area will reside under the parent node: - -`/local/domain/Y/device/vif/Z` - -All backends, by convention, typically reside under parent node: - -`/local/domain/X/backend` - -and the normal backend area for vif Z would be: - -`/local/domain/X/backend/vif/Y/Z` - -but this should not be assumed. - -The toolstack will place two nodes in the frontend area to explicitly locate -the backend: - - * `backend`: the fully qualified xenstore path of the backend area - * `backend-id`: the domid of the service domain - -and similarly two nodes in the backend area to locate the frontend area: - - * `frontend`: the fully qualified xenstore path of the frontend area - * `frontend-id`: the domid of the guest domain - - -The guest domain only has write permission to the frontend area and -similarly the service domain only has write permission to the backend area, -but both ends have read permission to both areas. - -Under both frontend and backend areas is a node called *state*. This is key -to protocol establishment. Upon PV device creation the toolstack will set -the value of both state nodes to 1 (XenbusStateInitialising[2]). This -should cause enumeration of appropriate devices in both the guest and -service domains. The backend device, once it has written any necessary -protocol specific information into the xenstore backend area (to be read -by the frontend driver) will update the backend state node to 2 -(XenbusStateInitWait). From this point on PV protocols differ slightly; the -following illustration is true of the netif protocol. - -Upon seeing a backend state value of 2, the frontend driver will then read -the protocol specific information, write details of grant references (for -shared pages) and event channel ports (for signalling) that it has created, -and set the state node in the frontend area to 4 (XenbusStateConnected). -Upon see this frontend state, the backend driver will then read the grant -references (mapping the shared pages) and event channel ports (opening its -end of them) and set the state node in the backend area to 4. Protocol -establishment is now complete and the frontend and backend start to pass -data. - -Because the domid of both ends of a PV protocol forms a key part of -negotiating the data plane for that protocol (because it is encoded into -both xenstore nodes and node paths), and because guest’s own domid and the -domid of the service domain are visible to the guest in xenstore (and hence -ay cached internally), and neither are necessarily preserved during -migration, it is hence necessary to have the co-operation of the frontend -in re-negotiating the protocol using the new domid after migration. - -Moreover the backend-id value will be used by the frontend driver in -setting up grant table entries and event channels to communicate with the -service domain, so the co-operation of the guest is required to -re-establish these in the new host environment after migration. - -Thus if we are to change the model and support migration of a guest with PV -drivers, without the co-operation of the frontend driver code, the paths and -values in both the frontend and backend xenstore areas must remain unchanged -and valid in the new host environment, and the grant table entries and event -channels must be preserved (and remain operational once guest execution is -resumed). - -Because the service domain’s domid is used directly by the guest in setting -up grant entries and event channels, the backend drivers in the new host -environment must be provided by service domain with the same domid. Also, -because the guest can sample its own domid from the frontend area and use -it in hypercalls (e.g. HVMOP_set_param) rather than DOMID_SELF, the guest -domid must also be preserved to maintain the ABI. - -Furthermore, it will necessary to modify backend drivers to re-establish -communication with frontend drivers without perturbing the content of the -backend area or requiring any changes to the values of the xenstore state -nodes. - -## Other Para-Virtual State - -### Shared Rings - -Because the console and store protocol shared pages are actually part of -the guest memory image (in an E820 reserved region just below 4G in x86 -VMs) then the content will get migrated as part of the guest memory image. -Hence no additional code is require to prevent any guest visible change in -the content. - -### Shared Info - -There is already a record defined in *libxenctrl Domain Image Format* [3] -called `SHARED_INFO` which simply contains a complete copy of the domain’s -shared info page. It is not currently incuded in an HVM (type `0x0002`) -migration stream. It may be feasible to include it as an optional record -but it is not clear that the content of the shared info page ever needs -to be preserved for an HVM guest. - -For a PV guest the `arch_shared_info` sub-structure contains important -information about the guest’s P2M, but this information is not relevant for -an HVM guest where the P2M is not directly manipulated via the guest. The -other state contained in the `shared_info` structure relates the domain -wall-clock (the state of which should already be transferred by the `RTC` -HVM context information which contained in the `HVM_CONTEXT` save record) -and some event channel state (particularly if using the *2l* protocol). -Event channel state will need to be fully transferred if we are not going -to require the guest co-operation to re-open the channels and so it should -be possible to re-build a shared info page for an HVM guest from such other -state. - -Note that the shared info page also contains an array of -`XEN_LEGACY_MAX_VCPUS` (32 for x86) `vcpu_info` structures. A domain may -nominate a different guest physical address to use for the vcpu info. This -is mandatory if a domain wants to use more than XEN_LEGACY_MAX_VCPUS vCPUs -and optional otherwise. This mapping is not currently transferred in the -migration state so this will either need to be added into an existing save -record, or an additional type of save record will be needed. - -### Xenstore Watches - -As mentioned above, no domain Xenstore state is currently transferred in -the migration stream. There is a record defined in *libxenlight Domain -Image Format* [4] called `EMULATOR_XENSTORE_DATA` for transferring Xenstore -nodes relating to emulators but no record type is defined for nodes -relating to the domain itself, nor for registered *watches*. A XenStore -watch is a mechanism used by PV frontend and backend drivers to request a -notification if the value of a particular node (e.g. the other end’s state -node) changes, so it is important that watches continue to function after a -migration. One or more new save records will therefore be required to -transfer Xenstore state. It will also be necessary to extend the *store* -protocol[5] with mechanisms to allow the toolstack to acquire the list of -watches that the guest has registered and for the toolstack to register a -watch on behalf of a domain. - -### Event channels - -Event channels are essentially the para-virtual equivalent of interrupts. -They are an important part of post PV protocols. Normally a frontend driver -creates an *inter-domain* event channel between its own domain and the -domain running the backend, which it discovers using the `backend-id` node -in Xenstore (see above), by making a `EVTCHNOP_alloc_unbound` hypercall. -This hypercall allocates an event channel object in the hypervisor and -assigns a *local port* number which is then written into the frontend area -in Xenstore. The backend driver then reads this port number and *binds* to -the event channel by specifying it, and the value of `frontend-id`, as -*remote domain* and *remote port* (respectively) to a -`EVTCHNOP_bind_interdomain` hypercall. Once connection is established in -this fashion frontend and backend drivers can use the event channel as a -*mailbox* to notify each other when a shared ring has been updated with new -requests or response structures. - -Currently no event channel state is preserved on migration, requiring -frontend and backend drivers to create and bind a complete new set of event -channels in order to re-establish a protocol connection. Hence, one or more -new save records will be required to transfer event channel state in order -to avoid the need for explicit action by frontend drivers running in the -guest. Note that the local port numbers need to preserved in this state as -they are the only context the guest has to refer to the hypervisor event -channel objects. - -Note also that the PV *store* (Xenstore access) and *console* protocols -also rely on event channels which are set up by the toolstack. Normally, -early in migration, the toolstack running on the remote host would set up a -new pair of event channels for these protocols in the destination domain. -These may not be assigned the same local port numbers as the protocols -running in the source domain. For non-cooperative migration these channels -must either be created with fixed port numbers, or their creation must be -avoided and instead be included in the general event channel state -record(s). - -### Grant table - -The grant table is essentially the para-virtual equivalent of an IOMMU. For -example, the shared rings of a PV protocol are *granted* by a frontend -driver to the backend driver by allocating *grant entries* in the guest’s -table, filling in details of the memory pages and then writing the *grant -references* (the index values of the grant entries) into Xenstore. The -grant references of the protocol buffers themselves are typically written -directly into the request structures passed via a shared ring. - -The guest is responsible for managing its own grant table. No hypercall is -required to grant a memory page to another domain. It is sufficient to find -an unused grant entry and set bits in the entry to give read and/or write -access to a remote domain also specified in the entry along with the page -frame number. Thus the layout and content of the grant table logically -forms part of the guest state. - -Currently no grant table state is migrated, requiring a guest to separately -maintain any state that it wishes to persist elsewhere in its memory image -and then restore it after migration. Thus to avoid the need for such -explicit action by the guest, one or more new save records will be required -to migrate the contents of the grant table. - -# Outline Proposal - -* PV backend drivers will be modified to unilaterally re-establish -connection to a frontend if the backend state node is restored with value 4 -(XenbusStateConnected)[6]. - -* The toolstack choose a randomized domid for initial creation or default -migration, but preserve the source domid non-cooperative migration. -Non-Cooperative migration will have to be denied if the domid is -unavailable on the target host, but randomization of domid on creation -should hopefully minimize the likelihood of this. Non-Cooperative migration -to localhost will clearly not be possible. - -* `xenstored` should be modified to implement the new mechanisms needed. -See *Other Para-Virtual State* above. A further design document will -propose additional protocol messages. - -* Within the migration stream extra save records will be defined as -required. See *Other Para-Virtual State* above. A further design document -will propose modifications to the libxenlight and libxenctrl Domain Image -Formats. - -* An option should be added to the toolstack to initiate a non-cooperative -migration, instead of the (default) potentially co-operative migration. -Essentially this should skip the check to see if PV drivers and migrate as -if there are none present, but also enabling the extra save records. Note -that at least some of the extra records should only form part of a -non-cooperative migration stream. For example, migrating event channel -state would be counter productive in a normal migration as this will -essentially leak event channel objects at the receiving end. Others, such -as grant table state, could potentially harmlessly form part of a normal -migration stream. - -* * * -[1] PV drivers are deemed to be installed if the HVM parameter -*HVM_PARAM_CALLBACK_IRQ* has been set to a non-zero value. - -[2] See https://xenbits.xen.org/gitweb/?p=xen.git;a=blob;f=xen/include/public/io/xenbus.h - -[3] See https://xenbits.xen.org/gitweb/?p=xen.git;a=blob;f=docs/specs/libxc-migration-stream.pandoc - -[4] See https://xenbits.xen.org/gitweb/?p=xen.git;a=blob;f=docs/specs/libxl-migration-stream.pandoc - -[5] See https://xenbits.xen.org/gitweb/?p=xen.git;a=blob;f=docs/misc/xenstore.txt - -[6] `xen-blkback` and `xen-netback` have already been modified in Linux to do -this. diff --git a/src/xen/docs/designs/qemu-deprivilege.md b/src/xen/docs/designs/qemu-deprivilege.md deleted file mode 100644 index 81a5f5c..0000000 --- a/src/xen/docs/designs/qemu-deprivilege.md +++ /dev/null @@ -1,322 +0,0 @@ -# Introduction - -The goal of deprilvileging qemu is this: Even if there is a bug (for -example in qemu) which permits a domain to gain control of the device -model, the compromised device model process is prevented from -violating the system's overall security properties.

These MSRs -allow any result to be returned, including the ability to advertise features -which are not actually supported. - -Intel CPUs between `Nehalem` and `SandyBridge` have differing numbers of -_Feature Mask_ MSRs, which are a simple AND-mask applied to all `CPUID` -instructions requesting specific feature bitmap sets.

These MSRs allow -features to be hidden by clearing the appropriate bit in the mask, but does -not allow unsupported features to be advertised. - -### CPUID Faulting - -Intel CPUs from `IvyBridge` onwards have _CPUID Faulting_, which allows Xen to -cause `CPUID` instruction executed in PV guests to fault. This allows Xen -full control over all information, exactly like HVM guests. - -## Compile time - -As some features depend on other features, it is important that, when -disabling a certain feature, we disable all features which depend on it. This -allows runtime logic to be simplified, by being able to rely on testing only -the single appropriate feature, rather than the entire feature dependency -chain. - -To speed up runtime calculation of feature dependencies, the dependency chain -is calculated and flattened by `xen/tools/gen-cpuid.py` to create -`xen/include/asm-x86/cpuid-autogen.h` from -`xen/include/public/arch-x86/cpufeatureset.h`, allowing the runtime code to -disable all dependent features of a specific disabled feature in constant -time. - -## Host boot - -As Xen boots, it will enumerate the features it can see.

On hardware with masking/override MSRs, the default MSR -values are picked from the *host_featureset*. - -The *host_featureset* is then used to calculate the *pv_featureset* and -*hvm_featureset*, which are the maximum featuresets Xen is willing to offer -to PV and HVM guests respectively. - -In addition, Xen will calculate how much control it has over non-cooperative -PV `CPUID` instructions, storing this information as *levelling_caps*. - -## Domain creation - -The toolstack can query each of the calculated featureset via -`XEN_SYSCTL_get_cpu_featureset`, and query for the levelling caps via -`XEN_SYSCTL_get_cpu_levelling_caps`. - -These data should be used by the toolstack when choosing the eventual -featureset to offer to the guest. - -Once a featureset has been chosen, it is set (implicitly or explicitly) via -`XEN_DOMCTL_set_cpuid`.

There is no way to -control certain behaviour such as the hardware MXCSR_MASK or x87 FPU exception -behaviour. - - -# Testing - -Feature levelling is a very wide area, and used all over the hypervisor. -Please ask on xen-devel for help identifying more specific tests which could -be of use. - - -# Known issues / Areas for improvement - -The feature querying and levelling functions should exposed in a -convenient-to-use way by `xl`. - -Xen currently has no concept of per-{socket,core,thread} CPUID information. -As a result, details such as APIC IDs, topology and cache information do not -match real hardware, and do not match the documented expectations in the Intel -and AMD system manuals. - -The CPU feature flags are the only information which the toolstack has a -sensible interface for querying and levelling. Other information in the CPUID -policy is important and should be levelled (e.g. maxphysaddr). - -The CPUID policy is currently regenerated from scratch by the receiving side, -once memory and vcpu content has been restored.

HW -enforces cache allocation according to the corresponding CBM. - -## The relationship between L3 CAT/CDP and L2 CAT - -HW may support all features. By default, CDP is disabled on the processor. -If the L3 CAT MSRs are used without enabling CDP, the processor operates in -a traditional CAT-only mode. When CDP is enabled: - -* the CAT mask MSRs are re-mapped into interleaved pairs of mask MSRs for - data or code fetches. - -* the range of COS for CAT is re-indexed, with the lower-half of the COS - range available for CDP. - -L2 CAT is independent of L3 CAT/CDP, which means L2 CAT can be enabled while -L3 CAT/CDP is disabled, or L2 CAT and L3 CAT/CDP are both enabled. - -As a requirement, the bits of CBM of CAT/CDP must be continuous. - -N.B. L2 CAT and L3 CAT/CDP share the same COS field in the same associate -register `IA32_PQR_ASSOC`, which means one COS is associated with a pair of -L2 CAT CBM and L3 CAT/CDP CBM. - -Besides, the max COS of L2 CAT may be different from L3 CAT/CDP (or other -PSR features in future). In some cases, a domain is permitted to have a COS -that is beyond one (or more) of PSR features but within the others. For -instance, let's assume the max COS of L2 CAT is 8 but the max COS of L3 -CAT is 16, when a domain is assigned 9 as COS, the L3 CAT CBM associated to -COS 9 would be enforced, but for L2 CAT, the HW works as default value is -set since COS 9 is beyond the max COS (8) of L2 CAT. - -## Design Overview - -* Core COS/CBM association - - When enforcing CAT/CDP, all cores of domains have the same default COS - (COS0) which is associated with the fully open CBM (all ones bitmask) to - access all cache. The default COS is used only in hypervisor and is - transparent to tool stack and user. - - System administrator can change PSR allocation policy at runtime by tool - stack. Since L2 CAT shares COS with L3 CAT/CDP, a COS corresponds to a - 2-tuple, like \[L2 CBM, L3 CBM\] with only-CAT enabled, when CDP is - enabled, one COS corresponds to a 3-tuple, like \[L2 CBM, L3 Code_CBM, - L3 Data_CBM\]. If neither L3 CAT nor L3 CDP is enabled, things would be - easier, one COS corresponds to one L2 CBM. - -* VCPU schedule - - When context switch happens, the COS of VCPU is written to per-thread MSR - `IA32_PQR_ASSOC`, and then hardware enforces cache allocation according to - the corresponding CBM. - -* Multi-sockets - - Different sockets may have different CAT/CDP capability (e.g. max COS) - although it is consistent on the same socket. So the capability of - per-socket CAT/CDP is specified. - - 'psr-cat-set' can set CBM for one domain per socket. On each socket, we - maintain a COS array for all domains. One domain uses one COS at one time. - One COS stores the CBM of the domain to work. So, when a VCPU of the domain - is migrated from socket 1 to socket 2, it follows configuration on socket 2. - - E.g. user sets domain 1 CBM on socket 1 to 0x7f which uses COS 9 but sets - domain 1 CBM on socket 2 to 0x3f which uses COS 7. When VCPU of this domain - is migrated from socket 1 to 2, the COS ID used is 7, that means 0x3f is the - CBM to work for this domain 1 now. - -## Implementation Description - -* Hypervisor interfaces: - - 1.

The purpose of the scheduler is enabling -deterministic and statically analyzable behavior (as per the -real-time academic literature), according to the scheduling parameters -assigned to each vCPU. - -Using RTDS a the Xen scheduler, and/or for general purpose workloads -is definitely possible, but the vCPU scheduling parameters (of both -Domain0 and of the various VMs) would probably require tweaking, with -respect to their default values. - -# Testing - -Any change done in RTDS must be tested by doing the following: - -* create a cpupool with RTDS as its scheduler, -* create a few virtual machines a move them in and out of the pool, -* create a few virtual machines, directly inside the pool, and verify - that they boot and can run some basic workload (e.g., login into them - and run simple commands), -* shutdown/reboot the virtual machines, - -The fact that the system boots fine when passing `sched=rtds` to Xen -should also be verified. - -Finally, to check that the scheduler is working properly (although only -at a macroscopic level), the following should be done: - -* create a VM with 1 vCPU and put it in the RTDS cpupool, -* set the scheduling parameters such as it has a 50% reservation, with - `xl sched-rtds -d vm -v all -p 100000 -b 50000`, -* run a CPU-burning process inside the VM (e.g., `yes`), -* check with `xentop` (in Domain0) that the VM is getting no more than - 50% pCPU time. - -# Areas for improvement - -* performance assessment, especially focusing on what level of real-time - behavior the scheduler enables. - -# Known issues - -* OSSTest reports occasional failures on ARM. - -# References - -* "RT-Xen: Real-Time Virtualization" [XPDS14 Presentation](http://events.linuxfoundation.org/sites/events/files/slides/2014_Xen_Developer_Summit_0.pdf) -* "Scheduling in Xen" [XPDS15 Presentation](http://events.linuxfoundation.org/sites/events/files/slides/Faggioli_XenSummit.pdf) -* [RT-Xen Project](https://sites.google.com/site/realtimexen/) -* [RTDS-Based-Scheduler](https://wiki.xenproject.org/wiki/RTDS-Based-Scheduler) -* "The RTDS Scheduler" [on the Xen-Project wiki](https://wiki.xenproject.org/wiki/RTDS-Based-Scheduler) -* "Xen Project Schedulers" [on the Xen-Project wiki](https://wiki.xenproject.org/wiki/Xen_Project_Schedulers) - -# History - ------------------------------------------------------------------------- -Date Revision Version Notes ----------- -------- -------- ------------------------------------------- -2016-10-14 1 Xen 4.8 Document written -2017-08-31 2 Xen 4.10 Revise for work conserving feature ----------- -------- -------- ------------------------------------------- diff --git a/src/xen/docs/features/template.pandoc b/src/xen/docs/features/template.pandoc deleted file mode 100644 index 82881e3..0000000 --- a/src/xen/docs/features/template.pandoc +++ /dev/null @@ -1,75 +0,0 @@ -% Template for feature documents -% Revision $N - -\clearpage - -This is a suggested template for formatting of a Xen feature document in -tree. - -The purpose of this document is to provide a concrete support statement -for the feature (indicating its security status), as well as brief user -and technical documentation. - -# Basics - -A table with an overview of the support status and applicability. - ----------------- ---------------------------------------------------- - Status: e.g. **Supported**/**Tech Preview**/**Experimental** - -Architecture(s): e.g. x86, arm - - Component(s): e.g. Hypervisor, toolstack, guest - - Hardware: _where applicable_ ----------------- ---------------------------------------------------- - -# Overview - -A short description the feature, similar to an abstract for a -paper/presentation. - -# User details - -Information for a user attempting to use the feature.

The default for tsc_mode handles the vast majority -of hardware and software environments. This document is targeted -for Xen users and administrators that may need to select a non-default -tsc_mode. - -Proper selection of tsc_mode depends on an understanding not only of -the guest operating system (OS), but also of the application set that will -ever run on this guest OS. This is because tsc_mode applies -equally to both the OS and ALL apps that are running on this -domain, now or in the future. - -Key questions to be answered for the OS and/or each application are: - -=over 4 - -=item * - -Does the OS/app use the rdtsc instruction at all? -(We will explain below how to determine this.) - -=item * - -At what frequency is the rdtsc instruction executed by either the OS -or any running apps? If the sum exceeds about 10,000 rdtsc instructions -per second per processor, we call this a "high-TSC-frequency" -OS/app/environment. (This is relatively rare, and developers of OS's -and apps that are high-TSC-frequency are usually aware of it.) - -=item * - -If the OS/app does use rdtsc, will it behave incorrectly if "time goes -backwards" or if the frequency of the TSC suddenly changes? If so, -we call this a "TSC-sensitive" app or OS; otherwise it is "TSC-resilient". - -=back - -This last is the US$64,000 question as it may be very difficult -(or, for legacy apps, even impossible) to predict all possible -failure cases. As a result, unless proven otherwise, any app -that uses rdtsc must be assumed to be TSC-sensitive and, as we -will see, this is the default starting in Xen 4.0. - -Xen's new tsc_mode parameter determines the circumstances under which -the family of rdtsc instructions are executed "natively" vs emulated. -Roughly speaking, native means rdtsc is fast but TSC-sensitive apps -may, under unpredictable circumstances, run incorrectly; emulated means -there is some performance degradation (unobservable in most cases), -but TSC-sensitive apps will always run correctly. Prior to Xen 4.0, -all rdtsc instructions were native: "fast but potentially incorrect." -Starting at Xen 4.0, the default is that all rdtsc instructions are -"correct but potentially slow".

The -command: - - # xl debug-key s; xl dmesg | tail - -provides information about TSC usage in each domain where TSC -emulation is currently enabled. - -=head1 TSC HISTORY - -To understand tsc_mode completely, some background on TSC is required: - -The x86 "timestamp counter", or TSC, is a 64-bit register on each -processor that increases monotonically. Historically, TSC incremented -every processor cycle, but on recent processors, it increases -at a constant rate even if the processor changes frequency (for example, -to reduce processor power usage). TSC is known by x86 programmers -as the fastest, highest-precision measurement of the passage of time -so it is often used as a foundation for performance monitoring. -And since it is guaranteed to be monotonically increasing and, at -64 bits, is guaranteed to not wraparound within 10 years, it is -sometimes used as a random number or a unique sequence identifier, -such as to stamp transactions so they can be replayed in a specific -order. - -On most older SMP and early multi-core machines, TSC was not synchronized -between processors. Thus if an application were to read the TSC on -one processor, then was moved by the OS to another processor, then read -TSC again, it might appear that "time went backwards". This loss of -monotonicity resulted in many obscure application bugs when TSC-sensitive -apps were ported from a uniprocessor to an SMP environment; as a result, -many applications -- especially in the Windows world -- removed their -dependency on TSC and replaced their timestamp needs with OS-specific -functions, losing both performance and precision. On some more recent -generations of multi-core machines, especially multi-socket multi-core -machines, the TSC was synchronized but if one processor were to enter -certain low-power states, its TSC would stop, destroying the synchrony -and again causing obscure bugs. This reinforced decisions to avoid use -of TSC altogether. On the most recent generations of multi-core -machines, however, synchronization is provided across all processors -in all power states, even on multi-socket machines, and provide a -flag that indicates that TSC is synchronized and "invariant". Thus -TSC is once again useful for applications, and even newer operating -systems are using and depending upon TSC for critical timekeeping -tasks when running on these recent machines. - -We will refer to hardware that ensures TSC is both synchronized and -invariant as "TSC-safe" and any hardware on which TSC is not (or -may not remain) synchronized as "TSC-unsafe". - -As a result of TSC's sordid history, two classes of applications use -TSC: old applications designed for single processors, and the most recent -enterprise applications which require high-frequency high-precision -timestamping. - -We will refer to apps that might break if running on a TSC-unsafe -machine as "TSC-sensitive"; apps that don't use TSC, or do use -TSC but use it in a way that monotonicity and frequency invariance -are unimportant as "TSC-resilient". - -The emergence of virtualization once again complicates the usage of -TSC. When features such as save/restore or live migration are employed, -a guest OS and all its currently running applications may be invisibly -transported to an entirely different physical machine. While TSC -may be "safe" on one machine, it is essentially impossible to precisely -synchronize TSC across a data center or even a pool of machines. As -a result, when run in a virtualized environment, rare and obscure -"time going backwards" problems might once again occur for those -TSC-sensitive applications. Worse, if a guest OS moves from, for -example, a 3GHz -machine to a 1.5GHz machine, attempts by an OS/app to measure time -intervals with TSC may without notice be incorrect by a factor of two. - -The rdtsc (read timestamp counter) instruction is used to read the -TSC register. The rdtscp instruction is a variant of rdtsc on recent -processors. We refer to these together as the rdtsc family of instructions, -or just "rdtsc". Instructions in the rdtsc family are non-privileged, but -privileged software may set a cpuid bit to cause all rdtsc family -instructions to trap. This trap can be detected by Xen, which can -then transparently "emulate" the results of the rdtsc instruction and -return control to the code following the rdtsc instruction. - -To provide a "safe" TSC, i.e. to ensure both TSC monotonicity and a -fixed rate, Xen provides rdtsc emulation whenever necessary or when -explicitly specified by a per-VM configuration option. TSC emulation is -relatively slow -- roughly 15-20 times slower than the rdtsc instruction -when executed natively. However, except when an OS or application uses -the rdtsc instruction at a high frequency (e.g. more than about 10,000 times -per second per processor), this performance degradation is not noticeable -(i.e. <0.3%). And, TSC emulation is nearly always faster than -OS-provided alternatives (e.g. Linux's gettimeofday). For environments -where it is certain that all apps are TSC-resilient (e.g. -"TSC-safeness" is not necessary) and highest performance is a -requirement, TSC emulation may be entirely disabled (tsc_mode==2). - -The default mode (tsc_mode==0) checks TSC-safeness of the underlying -hardware on which the virtual machine is launched. If it is -TSC-safe, rdtsc will execute at hardware speed; if it is not, rdtsc -will be emulated. Once a virtual machine is save/restored or migrated, -however, there are two possibilities: TSC remains native IF the source -physical machine and target physical machine have the same TSC frequency -(or, for HVM/PVH guests, if TSC scaling support is available); else TSC -is emulated. Note that, though emulated, the "apparent" TSC frequency -will be the TSC frequency of the initial physical machine, even after -migration. - -Finally, tsc_mode==1 always enables TSC emulation, regardless of -the underlying physical hardware. The "apparent" TSC frequency will -be the TSC frequency of the initial physical machine, even after migration. -This mode is useful to measure any performance degradation that -might be encountered by a tsc_mode==0 domain after migration occurs, -or a tsc_mode==3 domain when it is running on TSC-unsafe hardware. - -Note that while Xen ensures that an emulated TSC is "safe" across migration, -it does not ensure that it continues to tick at the same rate during -the actual migration. As an oversimplified example, if TSC is ticking -once per second in a guest, and the guest is saved when the TSC is 1000, -then restored 30 seconds later, TSC is only guaranteed to be greater -than or equal to 1001, not precisely 1030. This has some OS implications -as will be seen in the next section. - -=head1 TSC INVARIANT BIT and NO_MIGRATE - -Related to TSC emulation, the "TSC Invariant" bit is architecturally defined -in a cpuid bit on the most recent x86 processors. If set, TSC invariance -ensures that the TSC is "safe", that is it will increment at a constant rate -regardless of power events, will be synchronized across all processors, and -was properly initialized to zero on all processors at boot-time -by system hardware/BIOS. As long as system software never writes to TSC, -TSC will be safe and continuously incremented at a fixed rate and thus -can be used as a system "clocksource". - -This bit is used by some OS's, and specifically by Linux starting with -version 2.6.30(?), to select TSC as a system clocksource. Once selected, -TSC remains the Linux system clocksource unless manually overridden. In -a virtualized environment, since it is not possible to synchronize TSC -across all the machines in a pool or data center, a migration may "break" -TSC as a usable clocksource; while time will not go backwards, it may -not track wallclock time well enough to avoid certain time-sensitive -consequences. As a result, Xen can only expose the TSC Invariant bit -to a guest OS if it is certain that the domain will never migrate. -As of Xen 4.0, the "no_migrate=1" VM configuration option may be specified -to disable migration. If no_migrate is selected and the VM is running -on a physical machine with "TSC Invariant", Linux 2.6.30+ will safely -use TSC as the system clocksource. But, attempts to migrate or, once -saved, restore this domain will fail. - -There is another cpuid-related complication: The x86 cpuid instruction is -non-privileged. HVM domains are configured to always trap this instruction -to Xen, where Xen can "filter" the result. In a PV OS, all cpuid instructions -have been replaced by a paravirtualized equivalent of the cpuid instruction -("pvcpuid") and also trap to Xen. But apps in a PV guest that use a -cpuid instruction execute it directly, without a trap to Xen. As a result, -an app may directly examine the physical TSC Invariant cpuid bit and make -decisions based on that bit. - -=head1 HARDWARE TSC SCALING - -Intel VMX TSC scaling and AMD SVM TSC ratio allow the guest TSC read -by guest rdtsc/p increasing in a different frequency than the host -TSC frequency. - -If a HVM container in default TSC mode (tsc_mode=0) is created on a host -that provides constant TSC, its guest TSC frequency will be the same as -the host. If it is later migrated to another host that provides constant -TSC and supports Intel VMX TSC scaling/AMD SVM TSC ratio, its guest TSC -frequency will be the same before and after migration. - -For above HVM container in default TSC mode (tsc_mode=0), if above -hosts support rdtscp, both guest rdtsc and rdtscp instructions will be -executed natively before and after migration. - -=head1 AUTHORS - -Dan Magenheimer diff --git a/src/xen/docs/man/xen-vbd-interface.7.pandoc b/src/xen/docs/man/xen-vbd-interface.7.pandoc deleted file mode 100644 index ba0d159..0000000 --- a/src/xen/docs/man/xen-vbd-interface.7.pandoc +++ /dev/null @@ -1,135 +0,0 @@ -Xen guest interface -------------------- - -A Xen guest can be provided with block devices.

The only extra -software requirement for compiling vTPM is cmake. You must use libxl to manage -domains with vTPMs; 'xm' is deprecated and does not support vTPMs. - -=head2 Compiling the Xen tree: - -Compile and install the Xen tree as usual; be sure that the vTPM domains are -enabled when you run configure. - -=head2 Compiling the LINUX dom0 kernel: - -Because the TPM manager uses direct access to the physical TPM, it may interfere -with access to the TPM by dom0. The simplest solution for this is to prevent -dom0 from accessing the physical TPM by compiling the kernel without a driver or -blacklisting the module. If dom0 needs a TPM but does not need to use it during -the boot process (i.e. it is not using IMA), a virtual TPM can be attached to -dom0 after the system is booted. - -Access to the physical TPM may be required in order to manage the NVRAM or to -perform other advanced operations where the vTPM is insufficient. In order to -prevent interference, the TPM Manager and dom0 should use different values for -the TPM's locality; since Linux always uses locality 0, using locality 2 for the -TPM Manager is recommended. If both Linux and the TPM Manager attempt to access -the TPM at the same time, the TPM device will return a busy status; some -applications will consider this a fatal error instead of retrying the command at -a later time. If a vTPM gets an error when loading its key, it will currently -generate a fresh vTPM image (with a new EK, SRK, and blank NVRAM). - - -=head2 Compiling the LINUX domU kernel: - -The domU kernel used by domains with vtpms must include the xen-tpmfront.ko -driver. It can be built directly into the kernel or as a module; however, some -features such as IMA require the TPM to be built in to the kernel. - - CONFIG_TCG_TPM=y - CONFIG_TCG_XEN=y - -=head1 VTPM MANAGER SETUP - -=head2 Manager disk image setup: - -The vTPM Manager requires a disk image to store its encrypted data. The image -does not require a filesystem and can live anywhere on the host disk. The image -is not large; the Xen 4.5 vtpmmgr is limited to using the first 2MB of the image -but can support more than 20,000 vTPMs. - -=head2 Manager config file: - -The vTPM Manager domain (vtpmmgr-stubdom) must be started like any other Xen -virtual machine and requires a config file. The manager requires a disk image -for storage and permission to access the hardware memory pages for the TPM. The -disk must be presented as "hda", and the TPM memory pages are passed using the -iomem configuration parameter. The TPM TIS uses 5 pages of IO memory (one per -locality) that start at physical address 0xfed40000. By default, the TPM manager -uses locality 0 (so only the page at 0xfed40 is needed); this can be changed on -the domain's command line. For full functionality in deep quotes, using -locality 2 is required to manipulate PCR 20-22. - -=head2 Starting and stopping the manager: - -The vTPM manager should be started at boot; you may wish to create an init -script to do this. If a domain builder is used, the TPM Manager should be -started by the domain builder to minimize the trusted computing base for the -vTPM manager's secrets. - -Once initialization is complete you should see the following: - - INFO[VTPM]: Waiting for commands from vTPM's: - -The TPM Manager does not respond to shutdown requests; use the destroy command -to shut it down. - -=head1 VTPM AND LINUX PVM SETUP - -=head2 vTPM disk image setup: - -The vTPM requires a disk image to store its persistent data (RSA keys, NVRAM, -etc). The image does not require a filesystem. The image does not need to be -large; 2 Mb should be sufficient. - -=head2 vTPM config file: - -The vTPM domain requires a configuration file like any other domain. The vTPM -requires a disk image for storage and a TPM frontend driver to communicate with -the manager. You are required to generate a uuid for this vtpm, which is -specified on the C line that describes its connection to the vTPM Manager. -The uuidgen application may be used to generate a uuid, or one from the output -of the C command may be used to create a vTPM -belonging to a specific group. - -If you wish to clear the vTPM data you can either recreate the disk image or -change the uuid. - -=head2 Linux Guest config file: - -The Linux guest config file needs to be modified to include the Linux tpmfront -driver. Add the following line: - - vtpm=["backend=domu-vtpm"] - -Currently only Linux guests are supported (PV or HVM with PV drivers). - -While attaching a vTPM after a guest is booted (using xl vtpm-attach) is -supported, the attached vTPM will not have a record of the boot of the attached -guest. Furthermore, if the vTPM has been freshly created, a malicious guest -could then extend any values into PCRs, potentially forging its boot -configuration. Attaching a vTPM to a running domain should only be used for -trusted domains or when measurements have already been sent to the vTPM from -another source. - -=head2 Using the vTPM in the guest: - -If xen-tpmfront was compiled as a module, it must be loaded it in the guest. - - # modprobe xen-tpmfront - -After the Linux domain boots and the xen-tpmfront driver is loaded, you should -see the following on the vtpm console: - - Info: VTPM attached to Frontend X/Y - -You can quickly test the vTPM by using the sysfs interface: - - # cat /sys/devices/vtpm-0/pubek - # cat /sys/devices/vtpm-0/pcrs - -If you have trousers and tpm_tools installed on the guest, the tpm_version -command should return the following: - -The version command should return the following: - - TPM 1.2 Version Info: - Chip Version: 1.2.0.7 - Spec Level: 2 - Errata Revision: 1 - TPM Vendor ID: ETHZ - TPM Version: 01010000 - Manufacturer Info: 4554485a - -You should also see the command being sent to the vtpm console as well as the -vtpm saving its state. You should see the vtpm key being encrypted and stored on -the vtpmmgr console. - -You may wish to write a script to start your vtpm and guest together and to -destroy the vtpm when the guest shuts down. - -=head1 INTEGRATION WITH PV-GRUB - -The vTPM currently starts up with all PCRs set to their default values (all -zeros for the lower 16). This means that any decisions about the -trustworthiness of the created domain must be made based on the environment that -created the vTPM and the domU; for example, a system that only constructs images -using a trusted configuration and guest kernel be able to provide guarantees -about the guests and any measurements done that kernel (such as the IMA TCB -log). Guests wishing to use a custom kernel in such a secure environment are -often started using the pv-grub bootloader as the kernel, which then can load -the untrusted kernel without needing to parse an untrusted filesystem and kernel -in dom0. If the pv-grub stub domain succeeds in connecting to a vTPM, it will -extend the hash of the kernel that it boots into PCR #4, and will extend the -command line and initrd into PCR #5 before booting so that a domU booted in this -way can attest to its early boot state. - -=head1 MORE INFORMATION - -See for more details about how the manager domain works, how to use -it, and its command line parameters. - -=head1 VTPM DOMAIN OPERATION - -The vtpm-stubdom is a mini-OS domain that emulates a TPM for the guest OS to -use. It is a small wrapper around the Berlios TPM emulator version 0.7.4. -Commands are passed from the linux guest via the mini-os TPM backend driver. -vTPM data is encrypted and stored via a disk image provided to the virtual -machine. The key used to encrypt the data along with a hash of the vTPM's data -is sent to the vTPM manager for secure storage and later retrieval. The vTPM -domain communicates with the manager using a mini-os tpm front/back device pair. - -=head1 VTPM DOMAIN COMMAND LINE ARGUMENTS - -Command line arguments are passed to the domain via the 'extra' parameter in the -VM config file. Each parameter is separated by white space. For example: - - extra="foo=bar baz" - -=head2 List of Arguments: - -=over 4 - -=item B= - -Controls the amount of logging printed to the console. -The possible values for are: - -=over 4 - -=item * error - -=item * info (default) - -=item * debug - -=back - -=item B - -Start the Berlios emulator in "clear" mode.

These PCRs are populated in the -physical TPM during the boot process, either by the firmware/BIOS or by a -dynamic launch environment such as TBOOT. In order to provide assurance of the -system's security, the PCRs used to seal the TPM manager's data must contain -measurements for domains used to bootstrap the TPM Manager and vTPMs. - -Because these measurements are based on hashes, they will change any time that -any component of the system is upgraded. Since it is not possible to construct a -list of all possible future good measurements, the job of approving -configurations is delegated to a third party, referred to here as the system -approval agent (SAA). The SAA is identified by its public (RSA) signature key, -which is used to sign lists of valid configurations. A single TPM manager can -support multiple SAAs via the use of vTPM groups. Each group is associated with -a single SAA; this allows the creation of a multi-tenant environment where -tenants may not all choose to trust the same SAA. - -Each vTPM is bound to a vTPM group at the time of its creation. Each vTPM group -has its own AIK in the physical TPM for quotes of the hardware TPM state; when -used with a conforming Privacy CA, this allows each group on the system to form -the basis of a distinct identity. - -=head1 Initial Provisioning - -When the TPM Manager first boots up, it will create a stub vTPM group along with -entries for any vTPMs that communicate with it. This stub group must be -provisioned with an SAA and a boot configuration in order to survive a reboot. - -When a vTPM is connected to the TPM Manager using a UUID that is not recognized, -a slot will be created in group 0 for it. In the future, this auto-creation may -be restricted to specific UUIDs (such as the all-zero UUID) to enforce the use -of the TPM manager as the generator of the UUID. The first vTPM to be connected -is given administrative privileges for the TPM Manager, and should be attached -to dom0 or a control domain in order to send provisioning commands. - -Provisioning a vTPM group for the system requires the public key of the SAA and -privacy CA data used to certify the AIK (see the TPM spec for details).

Because of this, the TPM Manager trusts the UUID key in -Xenstore to identify a vTPM in a trusted manner. The XSM policy may be used to -strengthen this assumption if the creation of vTPM-labeled domains is more -constrained (for example, only permitted to a domain builder service): the only -grants mapped by the TPM Manager should belong to vTPM domains, so restricting -the ability to map other domain's granted pages will prevent other domains from -directly requesting keys from the TPM Manager. The TPM Manager uses the hash of -the XSM label of the attached vTPM as the kernel hash, so vTPMs with distinct -labels may be further partitioned using vTPM groups. - -A domain with direct access to the hardware TPM will be able to decrypt the TPM -Manager's disk image if the haredware TPM's PCR values are in a permitted -configuration. To protect the TPM Manager's data, the list of permitted -configurations should be chosen to include PCRs that measure the hypervisor, -domain 0, the TPM Manager, and other critical configuration such as the XSM -policy. If the TPM Manager is configured to use locality 2 as recommended, it -is safe to permit the hardware domain to access locality 0 (the default in -Linux), although concurrent use of the TPM should be avoided as it can result in -unexpected busy errors from the TPM driver. The ability to access locality 2 of -the TPM should be enforced using IO memory labeling in the XSM policy; the -physical address 0xFED42xxx is always locality 2 for TPMs using the TIS driver. - -=head1 Appendix: unsecured migration process for vtpmmgr domain upgrade - -There is no direct upgrade supported from previous versions of the vtpmmgr -domain due to changes in the on-disk format and the method used to seal data. -If a vTPM domain supports migration, this feature should be used to migrate the -vTPM's data; however, the vTPM packaged with Xen does not yet support migration. - -If adding migration support to the vTPM is not desired, a simpler migration -domain usable only for local migration can be constructed.
