Upstream Linux 3.11-3.17 uses older percpu_ref implementations whose memory lifetime and reinitialization rules do not support the revival needed when SCST cancels a suspend with outstanding commands. Maintaining those implementations requires a separate compatibility path. Require upstream Linux 3.18 or later and remove the eight 3.10-3.17 entries from the nightly matrix and the 3.10 selector from regression CI. Keep every distribution entry, including EL7 7.5-7.9 and UEK4/UEK5. EL7 has the newer percpu_ref implementation despite its 3.10 base version. Enforce the minimum and vendor exception in the shared build header. This is a support-policy change, not an analyzer-warning fix. It does not fix the remaining reinit-versus-resurrect mismatch on supported kernels.
This directory (nightly/) contains a simple, automatic build-and-test
system for SCST, intended to be run by cron.
Note (importantly) it doesn't test the sources in the tree of which
this directory is a part (viz, nightly/..). Instead it checks out
a complete new tree, builds and tests that independently of the
existing tree.
To use, choose a tag, probably a machine name, and run
bin/nightly <tag>
and supply the following two config files:
- conf/<tag>.conf: this is sourced by the 'nightly' script, and can define
any or all of the following environment variables:
ABT_DETAILS: describes the machine in more detail, eg. the OS. The default
is empty.
ABT_EVAL: if provided, it must be the name of a shell script that executes
the shell command $1 with arguments $2 .. ${$#}. Allows to compile and
run the SCST regression tests on another system than the system the
'nightly' script runs on. It is assumed that the remote system shares the
local filesystem tree through e.g. NFS. It is the responsibility of the
shell script to set the remote working directory such that it matches the
local current directory ($PWD).
ABT_JOBS: allows parallel builds -- it's passed as the argument to "make
-j" when building SCST and the tests. The default is 1.
ABT_KERNELS: kernel version numbers to test SCST against. The maintained
project list is in conf/nightly.conf.
ABT_TMPDIR: absolute path in which temporary files will be stored.
- conf/<tag>.sendmail: this should be a script that sends an email to the
desired recipient (eg. the scst-developers list). It takes three
command line arguments. The first is the email subject line, the second
is the name of the file containing the email's body (showing the tests
that failed, and the difference between now and 24 hours ago), the third
is the name of the file containing all the diffs (which can be made into
an attachment, for example).

The automatic build-and-test infrastructure for the SCST project reuses some
ideas and shell script code from a similar infrastructure in the Valgrind project.
