tools/testing/selftests/ipc/msgque.c: handle msgget failure return correctly

2014-03-11T00:26:21Z

A failed msgget causes the test to return an uninitialised value in ret. Assign ret to -errno on error exit. Signed-off-by: Colin Ian King Acked-by: Davidlohr Bueso Cc: Stanislav Kinsbursky Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

test: check copy_to/from_user boundary validation

2014-01-24T00:36:57Z

To help avoid an architecture failing to correctly check kernel/user boundaries when handling copy_to_user, copy_from_user, put_user, or get_user, perform some simple tests and fail to load if any of them behave unexpectedly. Specifically, this is to make sure there is a way to notice if things like what was fixed in commit 8404663f81d2 ("ARM: 7527/1: uaccess: explicitly check __user pointer when !CPU_USE_DOMAINS") ever regresses again, for any architecture. Additionally, adds new "user" selftest target, which loads this module. Signed-off-by: Kees Cook Cc: Rusty Russell Cc: Joe Perches Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

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

rcutorture: Flag errors and warnings with color coding

2013-12-03T18:11:18Z

The output of the rcutorture scripts often requires interpretation, so this commit simplifies this interpretation by tagging messages as BUGs (colored red) or WARNINGs (colored yellow). Reported-by: Ingo Molnar Signed-off-by: Paul E. McKenney Cc: Greg KH

rcutorture: Record results from repeated runs of the same test scenario

2013-12-03T18:11:18Z

Repeatedly running a given test, for example, by repeating the name as in "--configs "TREE08 TREE08 TREE08" records the results only of the last run of this test. This is because the earlier results are overwritten by the later results. This commit therefore checks for earlier results, using numbered file extensions to distinguish multiple runs. The earlier example would therefore create directories TREE01, TREE01.2, and TREE01.3. Signed-off-by: Paul E. McKenney Cc: Greg KH

rcutorture: Test summary at end of run with less chattiness

2013-12-03T18:11:18Z

The commit causes kvm.sh to invoke kvm-recheck.sh at the end of each run, and causes kvm-recheck.sh to print only the name of the test, not the full path to the corresponding Kconfig file. Signed-off-by: Paul E. McKenney Cc: Greg KH

rcutorture: Add tracing-enabled version of TREE08

2013-12-03T18:11:17Z

The TREE08 Kconfig fragment does not enable tracing, which is appropriate for its test case. However, this can be inconvenient in cases where TREE08 locates RCU bugs. This commit therefore adds a TREE08-T that differs from TREE08 only in enabling CONFIG_RCU_TRACE. Signed-off-by: Paul E. McKenney Cc: Greg KH

rcutorture: Add --kmake-arg argument to kvm.sh

2013-12-03T18:11:17Z

This commit adds the --kmake-arg to kvm.sh, which allows passing in things like "V=1" to see the build commands, as well as enabling the CROSS_COMPILE= make macro used for cross-building. Signed-off-by: Paul E. McKenney Cc: Greg KH
