2024-05-08ethernet: check destination mac for L3 in ethernet-input nodeSteven Luong1-1/+1
When the NIC does not support mac filter, we rely on ethernet-input node to do the destination mac check, ie, when the interface is in L3, the mac address for the packet must be the mac address of the interface where the packet arrives. This works fine in ethernet-input node when all packets in the frame might have different interfaces, ie, ETH_INPUT_FRAME_F_SINGLE_SW_IF_ID is not set in the frame. However, when all packets are having the same interface, ETH_INPUT_FRAME_F_SINGLE_SW_IF_ID is set, ethernet-input node goes through the optimized routine eth_input_single_int -> eth_input_process_frame. That is where dmac check has a bug when all packets in the frame are either, ip4, ip6, or mpls without vlan tags. Because without vlan tags, the code handles all packets in fast path and ignores dmac check. With vlan tags, the code goes to slow path where dmac check is handled properly. The fix is to check if we have a bad dmac in the fast path and force the code to go to slow path which will handle dmac check properly. Also do a wholesale correction on all the testcases which do not use the proper dmac when sending L3 packets.

2023-11-03tests: refactor asf framework codeDave Wallace1-21/+7
- Make framework.py classes a subset of asfframework.py classes - Remove all packet related code from asfframework.py - Add test class and test case set up debug output to log - Repatriate packet tests from asf to test directory - Remove non-packet related code from framework.py and inherit them from asfframework.py classes - Clean up unused import variables - Re-enable BFD tests on Ubuntu 22.04 and fix intermittent test failures in echo_looped_back testcases (where # control packets verified but not guaranteed to be received during test) - Re-enable Wireguard tests on Ubuntu 22.04 and fix intermittent test failures in handshake ratelimiting testcases and event testcase - Run Wiregard testcase suites solo - Improve debug output in log.txt - Increase VCL/LDP post sleep timeout to allow iperf server to finish cleanly. - Fix pcap history files to be sorted by suite and testcase and ensure order/timestamp is correct based on creation in the testcase. - Decode pcap files for each suite and testcase for all errors or if configured via comandline option / env var - Improve vpp corefile detection to allow complete corefile generation - Disable vm vpp interfaces testcases on debian11 - Clean up failed unittest dir when retrying failed testcases and unify testname directory and failed linknames into framwork functions Type: test Change-Id: I0764f79ea5bb639d278bf635ed2408d4d5220e1e Signed-off-by: Dave Wallace <dwallacelf@gmail.com>
2023-10-16ip-neighbor: do not use sas to determine NS source addressOle Troan1-1/+1
Using the source address selection algorithm to determine the best source of an NS for address resolution risks incompatible behavior. It may choose a source address that is off-link to the other host. Which may drop it. A safer approach is to always use the link-local address as the SA. It's recommended to pick a source that an application will later use, as VPP is mostly a router, that rarely applies. And regardlessly we have no mechanism to signal from an application that triggered address resolutiuon what source address it intends to use.

2022-05-10tests: replace pycodestyle with blackKlement Sekera1-45/+60
Drop pycodestyle for code style checking in favor of black. Black is much faster, stable PEP8 compliant code style checker offering also automatic formatting. It aims to be very stable and produce smallest diffs. It's used by many small and big projects. Running checkstyle with black takes a few seconds with a terse output. Thus, test-checkstyle-diff is no longer necessary. Expand scope of checkstyle to all python files in the repo, replacing test-checkstyle with checkstyle-python. Also, fixstyle-python is now available for automatic style formatting. Note: python virtualenv has been consolidated in test/Makefile, test/requirements*.txt which will eventually be moved to a central location. This is required to simply the automated generation of docker executor images in the CI.
