====================
pull-request: bpf 2019-01-08
The following pull-request contains BPF updates for your *net* tree.
The main changes are:
1) Fix BSD'ism in sendmsg(2) to rewrite unspecified IPv6 dst for
unconnected UDP sockets with [::1] _after_ cgroup BPF invocation,
from Andrey.
2) Follow-up fix to the speculation fix where we need to reject a
corner case for sanitation when ptr and scalars are mixed in the
same alu op. Also, some unrelated minor doc fixes, from Daniel.
3) Fix BPF kselftest's incorrect uses of create_and_get_cgroup()
by not assuming fd of zero value to be the result of an error
case, from Stanislav.
