+Subject: [PATCH] [linux] handle ffff:ffff in ipv6 addr correctly
+
+Close #102
+Close #109
+
+The listen address and port of an AF_INET6 socket were not display if
+the socket listened at an ipv6 address including ffff:ffff.
+
+Here is a command session demonstrating the bug:
+
+    # ip -6 addr add abcd:ef10:ffff:ffff:ffff:ffff:ffff:ff62 dev lo
+    # nc -6      -l  abcd:ef10:ffff:ffff:ffff:ffff:ffff:ff62 8888 &
+    [1] 6762
+    # ./lsof -p 6762 -a -d fd -P -n
+    COMMAND  PID   USER   FD   TYPE DEVICE SIZE/OFF    NODE NAME
+    nc      6762 yamato    0u   CHR  136,6      0t0       9 /dev/pts/6
+    nc      6762 yamato    1u   CHR  136,6      0t0       9 /dev/pts/6
+    nc      6762 yamato    2u   CHR  136,6      0t0       9 /dev/pts/6
+    nc      6762 yamato    3u  sock    0,9      0t0 5833594 protocol: TCPv6
+
+The last line should be:
+
+    nc      6762 yamato    3u  IPv6 5833594      0t0  TCP [abcd:ef10:ffff:ffff:ffff:ffff:ffff:ff62]:8888 (LISTEN)
+
+The original code decoding an ipv6 address uses UINT32_MAX constant
+incorrect way.
+
+@zhrf2020 reported this bug in #102.
+The test case is based on the report.
+
+@zhrf2020 provided the initial version of fix, #109.
+This change is based on the version.
