usr.sbin/bgpd : rde_community.c
Log message:
Avoid undefined behaviour in the community code by checking nentries to
be not 0 before memcmp, bsearch or siphash calls.
Calling these functions with a NULL pointer is UB even with a zero len.
While I did fix some code already during a review of all such possible
NULL, 0 calls I missed the bsearch one and introduced the community_equal
memcmp after that.
