rcu: Permit string-valued Kconfig options in kvm.sh

2023-01-04T01:53:32+00:00

This commit upgrades the kvm.sh script's --kconfig parameter to accept
string-valued Kconfig options with double-quoted string values.

torture: Permit double-quoted-string Kconfig options

2023-01-04T01:53:31+00:00

Currently, the presence of any quoted-string Kconfig option in the
scenario files or the CFcommon file (aside from the special-cased
CONFIG_INITRAMFS_SOURCE option) will result in an "improperly set"
diagnostic.  This commit updates configcheck.sh to strip double quotes
in order to permit string-valued Kconfig options to be handled correctly.

selftests: rcutorture: Use "grep -E" instead of "egrep"

2023-01-04T01:53:31+00:00

The latest version of grep is deprecating the egrep command, so that
its output contains warnings as follows:

	egrep: warning: egrep is obsolescent; using grep -E

Fix this using "grep -E" instead.

  sed -i "s/egrep/grep -E/g" `grep egrep -rwl tools/testing/selftests/rcutorture`

Here are the steps to install the latest grep:

  wget http://ftp.gnu.org/gnu/grep/grep-3.8.tar.gz
  tar xf grep-3.8.tar.gz
  cd grep-3.8 && ./configure && make
  sudo make install
  export PATH=/usr/local/bin:$PATH

torture: make kvm-find-errors.sh check for compressed vmlinux files

2023-01-04T01:53:31+00:00

Under some conditions, a given run's vmlinux file will be compressed,
so that it is named vmlinux.xz rather than vmlinux.  in such cases,
kvm-find-errors.sh will complain about the nonexistence of vmlinux.
This commit therefore causes kvm-find-errors.sh to check for vmlinux.xz
as well as for vmlinux.

torture: Make torture.sh create a properly formatted log file

2022-10-20T22:29:08+00:00

Currently, if the torture.sh allmodconfig step fails, this is counted as
an error (as it should be), but there is also an extraneous complaint
about a missing log file.  This commit therefore adds that log file,
which is hoped to reduce confused reactions to the error report.

rcutorture: Avoid torture.sh compressing identical files

2022-10-20T22:28:38+00:00

Currently, torture.sh will compress the vmlinux files for KASAN and
KCSAN runs.  But it will compress all of the files, including those
copied verbatim by the kvm-again.sh script.  Compression takes around ten
minutes, so this is not a good thing.  This commit therefore compresses
only one of a given set of identical vmlinux files, and then hard-links
it to the directories produced by kvm-again.sh.

rcutorture: Avoid redundant builds for rcuscale and refscale in torture.sh

2022-10-18T22:02:59+00:00

This commit causes torture.sh to use the new --bootargs and --datestamp
parameters to kvm-again.sh in order to avoid redundant kernel builds
during rcuscale and refscale testing.  This trims the better part of an
hour off of torture.sh runs that use --do-kasan.
