selftests: exec: revert to default emit rule

2015-09-14T22:45:05+00:00

With the previous patch, the installation method change from install
to rsync. There is no need to create subdir during test, the
default EMIT_TESTS is enough.

This patch essentially revert commit 84cbd9e4 ("selftests/exec: do not
install subdir as it is already created").

selftests: change install command to rsync

2015-09-14T22:43:51+00:00

The command of install could not handle the special files in exec
testcases, change the default rule to rsync to fix this.

The installation is unchanged after this commit.

selftests: mqueue: allow extra cflags

Change from = to += in order to allows the user to pass whatever
CFLAGS they wish(E.g. pass the proper headers and librareis
(popt.h and libpopt.so) in cross-compiling)

selftests: rename jump label to static_keys

2015-09-14T22:42:23+00:00

Commit 2bf9e0ab08c6 ("locking/static_keys: Provide a selftest")
renamed jump_label directory to static_keys and failed to update
the Makefile, causing the selftests build to fail.

This commit fixes it by updating the Makefile with the new name
and also moves the entry into the correct position to keep the
list alphabetically sorted.

selftests/seccomp: add support for s390

2015-09-14T22:41:37+00:00

This adds support for s390 to the seccomp selftests. Some improvements
were made to enhance the accuracy of failure reporting, and additional
tests were added to validate assumptions about the currently traced
syscall. Also adds early asserts for running on older kernels to avoid
noise when the seccomp syscall is not implemented.

seltests/zram: fix syntax error

2015-09-14T22:40:57+00:00

Not all shells define a variable UID. This is a bash and zsh feature only.
In other shells, the UID variable is not defined, so here test command
expands to [ != 0 ] which is a syntax error.

Without this patch:

zram.sh: 8: [: !=: unexpected operator
zram.sh : No zram.ko module or /dev/zram0 device file not found
zram.sh : CONFIG_ZRAM is not set

selftests: enhance membarrier syscall test

2015-09-11T22:21:34+00:00

Update the membarrier syscall self-test to match the membarrier
interface.  Extend coverage of the interface.  Consider ENOSYS as a
"SKIP" test, since it is a valid configuration, but does not allow
testing the system call.
