selftests: openvswitch: add a simple test for tunnel metadata

2025-09-14T21:28:13+00:00

This test ensures that upon receiving decapsulated packets from a tunnel interface in openvswitch, the tunnel metadata fields are properly populated. This partially covers interoperability of the kernel tunnel ports and openvswitch tunnels (LWT) and parsing and formatting of the tunnel metadata fields of the openvswitch netlink uAPI. Doing so, this test also ensures that fields and flags are properly extracted during decapsulation by the tunnel core code, serving as a regression test for the previously fixed issue with the DF bit not being extracted from the outer IP header. The ovs-dpctl.py script already supports all that is necessary for the tunnel ports for this test, so we only need to adjust the ovs_add_if() function to pass the '-t' port type argument in order to be able to create tunnel ports in the openvswitch datapath.

selftests: net: fix spelling and grammar mistakes

2025-09-01T20:08:07+00:00

Fix several spelling and grammatical mistakes in output messages from the net selftests to improve readability. Only the message strings for the test output have been modified. No changes to the functional logic of the tests have been made.

selftests: openvswitch: don't hardcode the drop reason subsys

2025-03-07T00:45:43+00:00

WiFi removed one of their subsys entries from drop reasons, in commit 286e69677065 ("wifi: mac80211: Drop cooked monitor support") SKB_DROP_REASON_SUBSYS_OPENVSWITCH is now 2 not 3. The drop reasons are not uAPI, read the correct value from debug info. We need to enable vmlinux BTF, otherwise pahole needs a few GB of memory to decode the enum name.

selftests: net/{lib,openvswitch}: extend CFLAGS to keep options from environment

2025-01-27T22:45:27+00:00

Package build environments like Fedora rpmbuild introduced hardening options (e.g. -pie -Wl,-z,now) by passing a -spec option to CFLAGS and LDFLAGS. Some Makefiles currently override CFLAGS but not LDFLAGS, which leads to a mismatch and build failure, for example: /usr/bin/ld: /tmp/ccd2apay.o: relocation R_X86_64_32 against `.rodata.str1.1' can not be used when making a PIE object; recompile with -fPIE /usr/bin/ld: failed to set dynamic section sizes: bad value collect2: error: ld returned 1 exit status make[1]: *** [../../lib.mk:222: tools/testing/selftests/net/lib/csum] Error 1 openvswitch/Makefile CFLAGS currently do not appear to be used, but fix it anyway for the case when new tests are introduced in future.

selftests: openvswitch: fix tcpdump execution

2024-12-19T03:18:41+00:00

Fix the way tcpdump is executed by: - Using the right variable for the namespace. Currently the use of the empty "ns" makes the command fail. - Waiting until it starts to capture to ensure the interesting traffic is caught on slow systems. - Using line-buffered output to ensure logs are available when the test is paused with "-p". Otherwise the last chunk of data might only be written when tcpdump is killed.

selftests: openvswitch: retry instead of sleep

2024-07-12T01:11:31+00:00

There are a couple of places where the test script "sleep"s to wait for some external condition to be met. This is error prone, specially in slow systems (identified in CI by "KSFT_MACHINE_SLOW=yes"). To fix this, add a "ovs_wait" function that tries to execute a command a few times until it succeeds. The timeout used is set to 5s for "normal" systems and doubled if a slow CI machine is detected. This should make the following work: $ vng --build \ --config tools/testing/selftests/net/config \ --config kernel/configs/debug.config $ vng --run . --user root -- "make -C tools/testing/selftests/ \ KSFT_MACHINE_SLOW=yes TARGETS=net/openvswitch run_tests" Signed-off-by: Adrian Moreno Reviewed-by: Ilya Maximets Link: https://patch.msgid.link/20240710090500.1655212-1-amorenoz@redhat.com Signed-off-by: Jakub Kicinski
