selftests: rds: Add -c config option to rds/config.sh

2026-03-24T02:39:07Z

This patch adds a new -c flag to config.sh that enables callers to specify the file path of the config they would like to update. If no config is specified, the default will be the .config of the current directory.

selftests: rds: add tools/testing/selftests/net/rds/config

2026-03-24T02:38:53Z

The ksft CI runtime needs an rds specific config file to build a minimal kernel with the right options enabled. This patch adds an rds selftest config containing the required CONFIG_RDS* and CONFIG_NET_* options.

selftests: rds: Fix tcpdump segfault in rds selftests

2026-03-11T01:54:24Z

net/rds/test.py sees a segfault in tcpdump when executed through the ksft runner. [ 21.903713] tcpdump[1469]: segfault at 0 ip 000072100e99126d sp 00007ffccf740fd0 error 4 [ 21.903721] in libc.so.6[16a26d,7798b149a000+188000] [ 21.905074] in libc.so.6[16a26d,72100e84f000+188000] likely on CPU 5 (core 5, socket 0) [ 21.905084] Code: 00 0f 85 a0 00 00 00 48 83 c4 38 89 d8 5b 41 5c 41 5d 41 5e 41 5f 5d c3 0f 1f 44 00 00 48 8b 05 91 8b 09 00 8b 4d ac 64 89 08 <41> 0f b6 07 83 e8 2b a8 fd 0f 84 54 ff ff ff 49 8b 36 4c 89 ff e8 [ 21.906760] likely on CPU 9 (core 9, socket 0) [ 21.913469] Code: 00 0f 85 a0 00 00 00 48 83 c4 38 89 d8 5b 41 5c 41 5d 41 5e 41 5f 5d c3 0f 1f 44 00 00 48 8b 05 91 8b 09 00 8b 4d ac 64 89 08 <41> 0f b6 07 83 e8 2b a8 fd 0f 84 54 ff ff ff 49 8b 36 4c 89 ff e8 The os.fork() call creates extra complexity because it forks the entire process including the python interpreter. ip() then calls cmd() which creates a subprocess.Popen. We can avoid the extra layering by simply calling subprocess.Popen directly. Track the process handles directly and terminate them at cleanup rather than relying on killall. Further tcpdump's -Z flag attempts to change savefile ownership, which is not supported by the 9p protocol. Fix this by writing pcap captures to "/tmp" during the test and move them to the log directory after tcpdump exits.

selftests: rds: Add ksft timeout

2026-03-11T01:54:15Z

rds/run.sh sets a timer of 400s when calling test.py. However when tests are run through ksft, a default 45s timer is applied.

selftests: net: unify the Makefile formats

2025-10-06T20:14:06Z

We get a significant number of conflicts between net and net-next because of selftests Makefile changes. People tend to append new test cases at the end of the Makefile when there's no clear sort order. Sort all networking selftests Makefiles, use the following format: VAR_NAME := \ entry1 \ entry2 \ entry3 \ # end of VAR_NAME Some Makefiles are already pretty close to this.

selftests: rds: move test.py to TEST_FILES

2024-11-28T09:20:17Z

The test.py should not be run separately. It should be run via run.sh, which will do some sanity checks first. Move the test.py from TEST_PROGS to TEST_FILES.
