torture: Skip vmlinux check for kvm-again.sh runs

2022-04-20T23:54:56Z

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

torture: Make kvm-find-errors.sh notice missing vmlinux file

2022-02-02T01:25:41Z

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.

torture: Make kvm-find-errors.sh report link-time undefined symbols

2021-12-01T01:30:28Z

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

torture: Make kvm-find-errors.sh account for kvm-remote.sh

2021-05-10T23:05:06Z

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

torture: Simplify exit-code plumbing for kvm-recheck.sh and kvm-find-errors.sh

2021-01-04T22:01:24Z

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

torture: Make kvm.sh return failure upon build failure

2021-01-04T22:01:22Z

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

rcutorture: Make kvm-find-errors.sh abort on bad directory

2020-02-21T00:03:30Z

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

torture: Make kvm-find-errors.sh and kvm-recheck.sh provide exit status

2019-05-28T16:06:09Z

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.

tools/.../rcutorture: Convert to SPDX license identifier

2019-03-26T21:42:53Z

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

torture: Make kvm-find-errors.sh find build warnings

2018-05-15T17:32:25Z

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 Tested-by: Nicholas Piggin
