Cover letter [PATCH bpf v2 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.

v1->v2:
* Fix compile error in patch 1.
