2022-04-20torture: Skip vmlinux check for kvm-again.sh runsPaul E. McKenney1-1/+1
The kvm-again.sh script reruns an previously built set of kernels, so the vmlinux files are associated with that previous run, not this on. This results in kvm-find_errors.sh reporting spurious failed-build errors. This commit therefore omits the vmlinux check for kvm-again.sh runs. Signed-off-by: Paul E. McKenney <paulmck@kernel.org>
2022-02-01torture: Make kvm-find-errors.sh notice missing vmlinux filePaul E. McKenney1-0/+6
Currently, an obtuse compiler diagnostic can fool kvm-find-errors.sh into believing that the build was successful. This commit therefore adds a check for a missing vmlinux file. Note that in the case of repeated torture-test scenarios ("--configs '2*TREE01'"), the vmlinux file will only be present in the first directory, that is, in TREE01 but not TREE01.2.

2021-11-30torture: Make kvm-find-errors.sh report link-time undefined symbolsPaul E. McKenney1-2/+2
This commit makes kvm-find-errors.sh check for and report undefined symbols that are detected at link time. Signed-off-by: Paul E. McKenney <paulmck@kernel.org>
2021-05-10torture: Make kvm-find-errors.sh account for kvm-remote.shPaul E. McKenney1-1/+1
Currently, kvm-find-errors.sh assumes that if "--buildonly" appears in the log file, then the run did builds but ran no kernels. This breaks with kvm-remote.sh, which uses kvm.sh to do a build, then kvm-again.sh to run the kernels built on remote systems. This commit therefore adds a check for a kvm-remote.sh run. While in the area, this commit checks for "--build-only" as well as "--build-only". Signed-off-by: Paul E. McKenney <paulmck@kernel.org>
2021-01-04torture: Simplify exit-code plumbing for kvm-recheck.sh and kvm-find-errors.shPaul E. McKenney1-0/+1
This commit simplifies exit-code plumbing. It makes kvm-recheck.sh return the value 1 for a build error and 2 for a runtime error. It also makes kvm-find-errors.sh avoid checking runtime files for --build-only runs. Signed-off-by: Paul E. McKenney <paulmck@kernel.org>
2021-01-04torture: Make kvm.sh return failure upon build failurePaul E. McKenney1-1/+7
The kvm.sh script uses kvm-find-errors.sh to evaluate whether or not a build failed. Unfortunately, kvm-find-errors.sh returns success if there are no failed runs (including when there are no runs at all) even if there are build failures. This commit therefore makes kvm-find-errors.sh return failure in response to build failures. Signed-off-by: Paul E. McKenney <paulmck@kernel.org>
2020-02-20rcutorture: Make kvm-find-errors.sh abort on bad directoryPaul E. McKenney1-0/+2
Currently, kvm-find-errors.sh gives a usage prompt when given a bad directory, but then soldiers on, giving a series of confusing error messages. This commit therefore prints an error message and exits when given a bad directory, hopefully reducing confusion. Signed-off-by: Paul E. McKenney <paulmck@kernel.org>
2019-05-28torture: Make kvm-find-errors.sh and kvm-recheck.sh provide exit statusPaul E. McKenney1-0/+3
This commit causes both kvm-find-errors.sh and kvm-recheck.sh to provide an exit status based on whether or not errors were located. In the case of kvm-recheck.sh, this will be the error status of the last run. This change allows these commands to be used in scripting and Makefiles to automatically report failed rcutorture runs.

2019-03-26tools/.../rcutorture: Convert to SPDX license identifierPaul E. McKenney1-0/+5
Replace the license boiler plate with a SPDX license identifier. While in the area, update an email address and add copyright notices. Signed-off-by: Paul E. McKenney <paulmck@linux.ibm.com>
2018-05-15torture: Make kvm-find-errors.sh find build warningsPaul E. McKenney1-2/+3
Currently, kvm-find-errors.sh looks only for build errors ("error:"), so this commit makes it also locate build warnings ("warning:"). Signed-off-by: Paul E. McKenney <paulmck@linux.vnet.ibm.com> Tested-by: Nicholas Piggin <npiggin@gmail.com>
2018-05-15torture: Add a script to edit output from failed runsPaul E. McKenney1-0/+55
This commit adds a script that allows viewing the build and/or console output from failed rcutorture, locktorture, or rcuperf runs. This replaces a time-honored but inefficient manual procedure that uses cut and paste. Signed-off-by: Paul E. McKenney <paulmck@linux.vnet.ibm.com> Tested-by: Nicholas Piggin <npiggin@gmail.com>
