2019-09-04ethernet: fix dmac check avx2 loop conditionMatthew Smith1-1/+1
In eth_input_process_frame(), a loop which checks the destination MAC address of received packets had a different condition for avx2 than it did for the non-avx2 version of the loop. It could result in one unnecessary execution of the loop body after all packets had been processed.

2019-05-16init / exit function orderingDave Barach4-30/+28
The vlib init function subsystem now supports a mix of procedural and formally-specified ordering constraints. We should eliminate procedural knowledge wherever possible. The following schemes are *roughly* equivalent: static clib_error_t *init_runs_first (vlib_main_t *vm) { clib_error_t *error; ... do some stuff... if ((error = vlib_call_init_function (init_runs_next))) return error; ... } VLIB_INIT_FUNCTION (init_runs_first); and static clib_error_t *init_runs_first (vlib_main_t *vm) { ... do some stuff... } VLIB_INIT_FUNCTION (init_runs_first) = { .runs_before = VLIB_INITS("init_runs_next"), }; The first form will [most likely] call "init_runs_next" on the spot. The second form means that "init_runs_first" runs before "init_runs_next," possibly much earlier in the sequence. Please DO NOT construct sets of init functions where A before B actually means A *right before* B. It's not necessary - simply combine A and B - and it leads to hugely annoying debugging exercises when trying to switch from ad-hoc procedural ordering constraints to formal ordering constraints.

2018-10-12vnet: complete the fix for l3_hdr_offset calculation for single loop ↵Andrew Yourtchenko1-1/+1
fastpass case (VPP-1444) 20e6d36b has moved the calculation of the l3_hdr_offset into the determine_next_node() function, with the assumption that the current_data in the buffer is at the L3 header. This is not the case for the single loop fastpath, where the vlib_buffer_advance() call is made after the call to determine_next_node(), as a day1 behavior. As a result - that path incorrectly sets the l3_hdr_offset. Solution: move the vlib_buffer_advance() call to before determine_next_node() Change-Id: Id5eaa084c43fb6564f8239df4a0b3dc0412b15de Signed-off-by: Andrew Yourtchenko <ayourtch@gmail.com> (cherry picked from commit 376414f4c3f53af44da4e82ee5d0b1843b291f8e)
2018-10-09vnet: ethernet-input incorrectly sets l3_hdr_offset in some casesAndrew Yourtchenko1-26/+26
The issue surfaced when developing the tap GSO code, with an iteration where output path is reliant on vnet_buffer (b0)->l3_hdr_offset being set correctly in the input path, during performance testing. Adding a workaround in the TX path shows that the issue surfaces only for relatively few packets during the test (about 100 out of 600000). Analysis shows the issue arises if the ethernet-input is handling two untagged packets with different sw_if_index values - then the accelerated path punts to slow path, before the setting of the l2.l2_len values is done, thus resulting in them being 0, and l3_hdr_offset being the same as l2_hdr_offset, wreaking havoc on TX path. The solution is to move the l2_hdr_offset calculation into a place where it is done for all the packets, and move the l3_hdr_offset calculation into the determine_next_node() function - as that function is also the one setting the special-case l2.l2_len value for tagged packets and moving the current_data for the L2 case.
