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: net: sort configs

2025-10-06T20:12:59Z

Sort config files for networking selftests. This should help us avoid merge conflicts between net and net-next. patchwork check will be added to prevent new issues.

selftests: hsr: Add test for VLAN

Add test for VLAN ping for HSR. The test adds vlan interfaces to the hsr interface and then verifies if ping to them works. Signed-off-by: MD Danish Anwar Reviewed-by: Jiri Pirko Link: https://patch.msgid.link/20241106091710.3308519-5-danishanwar@ti.com Signed-off-by: Jakub Kicinski

tests: hsr: Increase timeout to 50 seconds

2024-10-30T23:23:38Z

The HSR test, hsr_ping.sh, actually needs 7 min to run. Around 375s to be exact, and even more on a debug kernel or kernel with other network security limits. The timeout setting for the kselftest is currently 45 seconds, which is way too short to integrate hsr tests to run_kselftest infrastructure. However, timeout of hundreds of seconds is quite a long time, especially in a CI/CD environment. It seems that we need accelerate the test and balance with timeout setting. The most time-consuming func is do_ping_long, where ping command sends 10 packages to the given address. The default interval between two ping packages is 1s according to the ping Mannual. There isn't any operation between pings thus we could pass -i 0.1 to ping to make it 10 times faster. While even with this short interval, the test still need about 46.4 seconds to finish because of the two HSR interfaces, each of which is tested by calling do_ping func 12 times and do_ping_long func 19 times and sleep for 3s. So, an explicit setting is also needed to slightly increase the timeout. And to leave us some slack, use 50 as default timeout.

Fixed MAC addresses help with debugging as last four bytes identify the network namespace. Moreover, it allows to mimic the real life setup with for example bridge having the same MAC address on each port.

That is because the cleanup code for the 2nd round test before "setup_hsr_interfaces 1" is removed incorrectly in commit 680fda4f6714 ("test: hsr: Remove script code already implemented in lib.sh"). This patch fixes it by re-setup the namespaces using setup_ns ns1 ns2 ns3 command before "setup_hsr_interfaces 1". It deletes previous namespaces and create new ones.

test: hsr: Extend the hsr_redbox.sh to have more SAN devices connected

2024-05-13T23:02:22Z

After this change the single SAN device (ns3eth1) is now replaced with two SAN devices - respectively ns4eth1 and ns5eth1. It is possible to extend this script to have more SAN devices connected by adding them to ns3br1 bridge.
