selftests: mptcp: userspace_pm: fix undefined variable port

2026-07-23T17:50:38Z

In make_connection(), the variable "port" is used but never defined. This leads to an empty argument being passed to wait_local_port_listen(), causing "printf: : invalid number" errors: # INFO: Init # 01 Created network namespaces ns1, ns2 [ OK ] # INFO: Make connections # ./../lib.sh: line 651: printf: : invalid number # 02 Established IPv4 MPTCP Connection ns2 => ns1 [ OK ] # INFO: Connection info: 10.0.1.2:59516 -> 10.0.1.1:50002 # ./../lib.sh: line 651: printf: : invalid number # 03 Established IPv6 MPTCP Connection ns2 => ns1 [ OK ] Fix it by using the correctly defined variable "app_port", which holds the appropriate port number for the connection.

selftests/net: packetdrill: cover RST validation in SYN-RECEIVED

2026-07-23T15:27:22Z

Add packetdrill coverage for the RFC 9293 reset checks on request sockets in SYN-RECEIVED. Verify that an exact RST removes the request, a non-exact in-window RST sends a challenge ACK without removing it, and an out-of-window RST is silently discarded. Also cover an RST|ACK with an unacceptable ACK number to ensure RST sequence validation runs before ACK-field validation.

selftests: netconsole: ignore busywait errors

2026-07-21T22:01:30Z

In these netconsole tests, bash is used with errexit (set -e). It means that if the busywait timeout, the tests finish without printing an error message. It is fine to ignore these errors, because the following validate_xxx helpers will check the content of the output file, and exit with an appropriated error message, e.g. FAIL: File was not generated.

selftests: drv-net: add missing kconfig for psp.py

2026-07-21T22:01:30Z

This psp.py selftest was failing on my side when only using the drivers/net config file on top of the default one -- the recommended way to execute selftest targets. It looks like some kernel config are needed to execute the new tc commands. Note that this was not visible on NIPA, because these tests are executed with the drivers/net/hw ones, combining the two config files, and the hw one contains the missing ones.

selftests: drv-net: increase timeout

2026-07-21T22:01:30Z

The default timeout is 45 seconds, that's too low for the xdp.py test. Indeed, this test can take up to 3 minutes with some debug kernel config on NIPA. Set a timeout to 6 minutes, just to be on the safe side. Note that the Fixes tag here points to the introduction of the xdp.py test because I don't know when this test started to take more than 45 seconds. That's OK because a timeout of 6 minutes is not exaggerated.
