2020-08-18vppinfra: enable STATIC_ASSERT with clangBenoît Ganne1-4/+0
For some reason clang does not support &((struct foo*)0)->field in static assertion contrary to gcc. Use offsetof() macro implementation provided by both compilers instead. Type: fix Change-Id: I3311cdd29c5861e45dc0ef92f2bbd66242ca73b8 Signed-off-by: Benoît Ganne <bganne@cisco.com> (cherry picked from commit 5e60c17f49082b7731778e81b58177177a31b58f)
2020-08-12misc: fix coverity warningsDave Barach1-0/+29
Add an ALWAYS_ASSERT (...) macro, to (a) shut up coverity, and (b) check the indicated condition in production images. As in: p = hash_get(...); ALWAYS_ASSERT(p) /* was ASSERT(p) */ elt = pool_elt_at_index(pool, p[0]); This may not be the best way to handle a specific case, but failure to check return values at all followed by e.g. a pointer dereference isn't ok.

2019-09-09dpdk: initialize rte_mbuf during mempool dequeueDamjan Marion1-0/+3
In some cases it may happen that buffer is allocated by DPDK, and freed by VPP native code. In such cases dpdk metadata is not reset, so we need to do that during mempool dequeue. Template approach is taken to reduce cost of that operation. Type: fix Fixes: 910d369 Change-Id: Ic239007cfc8fbceb965021c56963cda9d53f63be Signed-off-by: Damjan Marion <damarion@cisco.com>
