2021-02-19policer: move handoff checks into policer codeBrian Russell4-47/+41
The IP punt policer currently checks if it needs to do worker thread handoff based on the thread index stored in the policer. Move this functionality into the policer code so it can be common for all users of the policer.

2021-02-15vlib: refactor checksum offload supportMohsin Kazmi34-264/+377
Type: refactor This patch refactors the offload flags in vlib_buffer_t. There are two main reasons behind this refactoring. First, offload flags are insufficient to represent outer and inner headers offloads. Second, room for these flags in first cacheline of vlib_buffer_t is also limited. This patch introduces a generic offload flag in first cacheline. And detailed offload flags in 2nd cacheline of the structure for performance optimization.

In the forwarding plane the MTU is enfored either: 1 - if the peer is attached, then the MTU is set on the peer's adjacency 2 - if the peer is not attached, it is remote, then a DPO is added to the peer's FIB entry to perform the necessary fragmentation.

2021-02-15vppinfra: fix memcpy undefined behaviourBenoît Ganne6-80/+123
Calling mem{cpy,move} with NULL pointers results in undefined behaviour. This in turns is exploited by GCC. For example, the sequence: memcpy (dst, src, n); if (!src) return; src[0] = 0xcafe; will be optimized as memcpy (dst, src, n); src[0] = 0xcafe; IOW the test for NULL is gone. vec_*() functions sometime call memcpy with NULL pointers and 0 length, triggering this optimization. For example, the sequence: vec_append(v1, v2); len = vec_len(v2); will crash if v2 is NULL, because the test for NULL pointer in vec_len() has been optimized out. This commit fixes occurrences of such undefined behaviour, and also introduces a memcpy wrapper to catch those in debug mode.
