ktest.pl: Add new PATCHCHECK_SKIP option to skip testing individual commits

2025-07-29T13:30:08+00:00

When testing a series of commits that also includes changes to the Linux tools directory, it is useless to test the changes in tools as they may not affect the kernel itself. Doing tests on the kernel for changes that do not affect the kernel is a waste of time. Add a PATCHCHECK_SKIP that takes a series of shas that will be skipped while doing the individual commit tests. For example, the runtime verification may have a series of commits like: $ git log --abbrev-commit --pretty=oneline fac5493251a6~1..HEAD 3d3800b4f7f4 rv: Remove rv_reactor's reference counter 3d3c376118b5 rv: Merge struct rv_reactor_def into struct rv_reactor 24cbfe18d55a rv: Merge struct rv_monitor_def into struct rv_monitor b0c08dd5348d rv: Remove unused field in struct rv_monitor_def 58d5f0d437a8 (debiantesting-x86-64/trace/rv/core) rv: Return init error when registering monitors 560473f2e2d7 verification/rvgen: Organise Kconfig entries for nested monitors 9efcf590827c tools/dot2c: Fix generated files going over 100 column limit 1160ccaf772f tools/rv: Stop gracefully also on SIGTERM f60227f34489 tools/rv: Do not skip idle in trace f3735df6281e verification/rvgen: Do not generate unused variables 6fb37c2a27eb verification/rvgen: Generate each variable definition only once 8cfcf9b0e92f verification/rvgen: Support the 'next' operator fac5493251a6 rv: Allow to configure the number of per-task monitor Where the first commit touches the kernel followed by a series of commits that do not, and ends with commits that do. Instead of having to add multiple patchcheck tests to handle the gaps, just include the commits that should not be tested: $ git log --abbrev-commit --pretty=oneline fac5493251a6~1..HEAD | grep -e verification -e tools/ | cut -d' ' -f1 | while read a ; do echo -n "$a "; done 560473f2e2d7 9efcf590827c 1160ccaf772f f60227f34489 f3735df6281e 6fb37c2a27eb 8cfcf9b0e92f Then set PATCHCHECK_SKIP to that, and those commits will be skipped.

ktest.pl: Add RUN_TIMEOUT option with default unlimited

2023-02-20T16:52:27+00:00

There is a disconnect between the run_command function and the wait_for_input. The wait_for_input has a default timeout of 2 minutes. But if that happens, the run_command loop will exit out to the waitpid() of the executing command. This fails in that it no longer monitors the command, and also, the ssh to the test box can hang when its finished, as it's waiting for the pipe it's writing to to flush, but the loop that reads that pipe has already exited, leaving the command stuck, and the test hangs. Instead, make the default "wait_for_input" of the run_command infinite, and allow the user to override it if they want with a default timeout option "RUN_TIMEOUT". But this fixes the hang that happens when the pipe is full and the ssh session never exits.

ktest.pl: Add shell commands to variables

2022-12-09T04:23:05+00:00

Allow variables to execute shell commands. Note, these are processed when they are first seen while parsing the config file. This is useful if you have the same config file used for multiple hosts (as they may be in a git repository). HOSTNAME := ${shell hostname} DEFAULTS IF "${HOSTNAME}" == "frodo" Link: https://lkml.kernel.org/r/20221207212944.277ee850@gandalf.local.home Signed-off-by: Steven Rostedt (Google)

ktest.pl: Add MAIL_MAX_SIZE to limit the amount of log emailed

2020-07-02T13:55:04+00:00

Add the ktest config option MAIL_MAX_SIZE that will limit the size of the log file that is placed into the email on failure. Link: https://lore.kernel.org/r/20200701231756.790637968@goodmis.org Reviewed-by: Greg Kroah-Hartman Signed-off-by: Steven Rostedt (VMware)

ktest.pl: Define PRE_TEST_DIE to kill the test if the PRE_TEST fails

2020-07-01T14:35:48+00:00

Currently, if a PRE_TEST is defined and ran, but fails, there's nothing currently available to make the test fail too. Add a PRE_TEST_DIE option that when set, if a PRE_TEST is defined and fails, the test will die too. Signed-off-by: Steven Rostedt (VMware)

ktest: Make default build option oldconfig not randconfig

2020-03-09T20:04:30+00:00

For the last time, I screwed up my ktest config file, and the build went into the default "randconfig", blowing away the .config that I had set up. The reason for the default randconfig was because when this was first written, I wanted to do a bunch of randconfigs. But as time progressed, ktest isn't about randconfig anymore, and because randconfig destroys the config in the build directory, it's a dangerous default to have. Use oldconfig as the default.

ktest: introduce REBOOT_RETURN_CODE to confirm the result of REBOOT

2019-04-18T15:25:13+00:00

Unexpected power cycle occurs while the installation of the kernel. ssh root@Test sync ... [0 seconds] SUCCESS ssh root@Test reboot ... [1 second] FAILED! virsh destroy Test; sleep 5; virsh start Test ... [6 seconds] SUCCESS That is because REBOOT, the default is "ssh $SSH_USER@$MACHINE reboot", exits as 255 even if the reboot is successfully done, like as: ]# ssh root@Test reboot Connection to Test closed by remote host. ]# echo $? 255 ]# To avoid the unexpected power cycle, introduce a new parameter, REBOOT_RETURN_CODE to judge whether REBOOT is successfully done or not.
