Subject: [PATCH bpf 0/2] bpf: Fix [::] -> [::1] rewrite in sys_sendmsg

The patch set fixes BSD'ism in sys_sendmsg to rewrite unspecified
destination IPv6 for unconnected UDP sockets in sys_sendmsg with [::1] in
case when either CONFIG_CGROUP_BPF is enabled or when sys_sendmsg BPF hook
sets destination IPv6 to [::].

Patch 1 is the fix and provides more details.
Patch 2 adds two test cases to verify the fix.

Andrey Ignatov (2):
  bpf: Fix [::] -> [::1] rewrite in sys_sendmsg
  selftests/bpf: Test [::] -> [::1] rewrite in sys_sendmsg in test_sock_addr
