f61018dc - selftests: forwarding: pedit_dsfield: Disable IPv6 autogen on a bridge

selftests: forwarding: pedit_dsfield: Disable IPv6 autogen on a bridgeIn a future patch, mlxsw will start adding RIFs to uppers of front panelport netdevices, if they have an IP address.At the time that the front panel port is enslaved to the bridge, the bridgeMAC address does not have the same prefix as other interfaces in thesystem. On Nvidia Spectrum-1 machines all the RIFs have to have the same38-bit MAC address prefix. Since the bridge does not obey this limitation,the RIF cannot be created, and the enslavement attempt is vetoed on thegrounds of the configuration not being offloadable.The selftest itself however checks whether skbedit changes packet priorityas appropriate. The bridge thus does not need to participate in routingtraffic and the IP address or the RIF are irrelevant.Fix by disabling automatic IPv6 address generation for the HW-offloadedbridge in this selftest, thus exempting it from mlxsw router attention.Since the bridge is only used for L2 forwarding, this change should nothinder usefulness of this selftest for testing SW datapath or HW datapathsin other devices.Signed-off-by: Petr Machata Reviewed-by: Danielle Ratson Signed-off-by: Jakub Kicinski List of files: /linux-6.15/tools/testing/selftests/net/forwarding/skbedit_priority.sh

e67dfb8d - selftests: Clean forgotten resources as part of cleanup()

selftests: Clean forgotten resources as part of cleanup()Several tests do not set some ports down as part of their cleanup(),resulting in IPv6 link-local addresses and associated routes not beingdeleted.These leaks were found using a BPF tool that monitors ASIC resources.Solve this by setting the ports down at the end of the tests.Signed-off-by: Amit Cohen Reviewed-by: Petr Machata Signed-off-by: Ido Schimmel Signed-off-by: David S.

2a0b1307 - selftests: skbedit_priority: Test counters at the skbedit rule

Thu, 26 Mar 2020 20:45:57 +0000

selftests: skbedit_priority: Test counters at the skbedit ruleCurrently the test checks the observable effect of skbedit priority:queueing of packets at the correct qdisc band. It therefore misses the factthat the counters for offloaded rules are not updated. Add an extra checkfor the counter.Signed-off-by: Petr Machata Signed-off-by: David S.

26d9f0cd - selftests: forwarding: Add an skbedit priority selftest

Thu, 19 Mar 2020 13:47:24 +0000

selftests: forwarding: Add an skbedit priority selftestAdd a test that runs traffic through a port such that skbedit priorityaction acts on it during forwarding. Test that at egress, it is classifiedcorrectly according to the new priority at a PRIO qdisc.Signed-off-by: Petr Machata Signed-off-by: Ido Schimmel Signed-off-by: David S.
