2022-06-05wireguard: fix crash by not sending arp via wg interfaceAlexander Chernavin2-1/+9
Type: fix Currently, neighbor adjacencies on a wg interface are converted into a midchain only if one of the peers has a matching allowed prefix configured. If create a route that goes through a wg interface but the next-hop address does not match any allowed prefixes, an ARP/ND request will try to be sent via the wg interface to resolve the next-hop address when matching traffic occurs. And sending an ARP request will cause VPP to crash while copying hardware address of the wg interface which is NULL. Sending an ND message will not cause VPP to crash but the error logged will be unclear (no source address). With this fix, convert all neighbor adjacencies on a wg interface into a midchain and update tests to cover the case. If there is no matching allowed prefix configured, traffic going such routes will be dropped because of "Peer error". No changes if there is matching allowed prefix configured. Also, fix getting peer by adjacency index. Signed-off-by: Alexander Chernavin <achernavin@netgate.com> Change-Id: I15bc1e1f83de719e97edf3f7210a5359a35bddbd

2022-06-02ipfix-export: Fix frame leak in flow_report_process_send()Jon Loeliger1-1/+9
The flow_report_process_send() function always allocates a frame. However, when no template_send is needed, template_bi is ~0. When this happens, no vectors are placed in the frame. When the frame is then "put", a check for n_vectors == 0 prevents the frame from actually being placed back on the free list. Fix that by using a direct call to vlib_frame_free() when there are no frame vctors. Type: fix Signed-off-by: Jon Loeliger <jdl@netgate.com> Change-Id: I936b5cea4cb3c358247c3d2e1a77d034a322ea76

2022-05-31nat: disable nat44-ei-in2out-output ttl checkAlexander Skorichenko1-3/+3
Type: fix A packet passing through nat44-ei-in2out-output, has its ttl value validated in earlier nodes. "ip4-input" node checks ttl for locally generated packets. "ip4-rewrite" node validates ttl in forwarded packets. Thus for example, the ED counterpart disables ttl checks in its "nat44-ed-in2out-output" node. This patch updates nat44 EI conditions for ttl checks to those currently used in nat44 ED case, meaning no extra ttl validation for in2out when output-feature is enabled.

2022-05-19stats: fix collector updates of symlinksArthur de Kerhor1-3/+9
A node name is not bound to a node index. For example, if an interface is deleted and re-added, the indexes of its nodes "<itfc_name>-tx" and "<itfc_name>-output" may change. Thus, when the collector updates the nodes stats, it should first delete all the symlinks for nodes that have changed their names before adding new symlinks. Otherwise, it could attempt to add already existing symlinks or delete valid ones. Example of a series of command that triggers a crash in the assert `ASSERT (node_data[i].symlinks[j] != CLIB_U32_MAX);`: ``` create loopback interface create loopback interface ``` Wait for the nodes stats to update, then: ``` delete loopback interface intfc loop0 delete loopback interface intfc loop1 create loopback interface create loopback interface ``` Type: fix Change-Id: Ief8e7135e5c02dc6bc64dc94b76cff21ea9ab3a9 Signed-off-by: Arthur de Kerhor <arthurdekerhor@gmail.com>

2022-05-17interface: fix overflow of link speed.Anton Nikolaev4-8/+13
Type: fix There were several places where mbps were converted to kbps for link_speed, but often drivers of devices set link speed to unknown (0xFFFFFFFF) on initialization, so there was multiplication of link_speed equal 0xFFFFFFFF(UINT32_MAX) by 1000, this provides overflow of unsigned int, and as result link_speed was equal 4295 Gbps, but actually link_speed is unknown.

2022-05-10tests: replace pycodestyle with blackKlement Sekera43-3989/+4955
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.
