torture: Use mktemp instead of guessing at unique names

2022-10-18T22:02:59Z

This commit drags the rcutorture scripting kicking and screaming into the twenty-first century by making use of the BSD-derived mktemp command to create temporary files and directories. In happy contrast to many of its ill-behaved predecessors, mktemp seems to actually work reasonably reliably! Signed-off-by: Paul E. McKenney

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

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: Allow standalone kvm-recheck.sh run detect --trust-make

2021-01-04T22:01:25Z

Normally, kvm-recheck.sh is run from kvm.sh, which provides the TORTURE_TRUST_MAKE environment variable that, if a non-empty string, indicates that the --trust-make command-line parameter has been passed to kvm.sh. If there was no --trust-make, kvm-recheck.sh insists that the Make.out file contain at least one "CC" command. Thus, when kvm-recheck.sh is run standalone to evaluate a prior --trust-make run, it will incorrectly insist that a proper kernel build did not happen. This commit therefore causes kvm-recheck.sh to also search the "log" file in the top-level results directory for the string "--trust-make". Signed-off-by: Paul E. McKenney

torture: Add --trust-make to suppress "make clean"

2019-05-28T16:06:09Z

The current rcutorture scripts unconditionally do "make clean", which is a good way of getting the needed testing done despite any imperfections in Makefile dependency tracking. However, this can be a bit irritating when repeatedly running a single scenario after small changes, for example, when debugging a problem that affects only a single scenario. This commit therefore adds a --trust-make argument that suppresses the "make clean". Even when using ccache, this speeds up kernel builds by up to almost an order of magnitude on my laptop.

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: Provide TMPDIR environment variable to specify tmpdir

2017-10-09T21:26:09Z

Both rcutorture and locktorture currently place temporary files in /tmp, in keeping with decades-long tradition. However, sometimes it is useful to specify an alternative temporary directory, for example, for space or performance reasons. This commit therefore causes the torture-test scripting to use the path specified in the TMPDIR environment variable, or to fall back to traditional /tmp if this variable is not set.

rcutorture: Set executable bit and drop bash from Usage

2014-09-07T23:24:38Z

This commit sets the executable bit on test scripts config2frag.sh and kvm.sh. Since #!/bin/bash is set in all the scripts, this commit also drops it from all usage lines because the scripts can now all be invoked directly. Signed-off-by: Pranith Kumar Signed-off-by: Paul E. McKenney

rcutorture: Use bash shell for all the test scripts

2014-09-07T23:24:32Z

Some of the scripts encode a default /bin/sh shell. On systems which use dash as default shell, these scripts fail as they are bash scripts. I encountered this while testing the sprintf() changes on a Debian system where dash is the default shell. This commit changes all such uses to use bash explicitly.

rcutorture: Stop tracking FSF's postal address

2013-12-03T18:11:19Z

All of the rcutorture scripts has the usual GPL header, which contains a long-obsolete postal address for FSF. To avoid the need to track the FSF office's movements, this commit substitutes the URL where GPL may be found. Reported-by: Greg KH Reported-by: Steven Rostedt Signed-off-by: Paul E. McKenney
