[ Upstream commit 7c27a26e1ed5a7dd709aa19685d2c98f64e1cf0c ]
There are some powerpc selftests, as tm/tm-unavailable, that run for a long
period (>120 seconds), and if it is interrupted, as pressing CRTL-C
(SIGINT), the foreground process (harness) dies but the child process and
threads continue to execute (with PPID = 1 now) in background.
In this case, you'd think the whole test exited, but there are remaining
threads and processes being executed in background. Sometimes these
zombies processes are doing annoying things, as consuming the whole CPU or
dumping things to STDOUT.
This patch fixes this problem by attaching an empty signal handler to
SIGINT in the harness process. This handler will interrupt (EINTR) the
parent process waitpid() call, letting the code to follow through the
normal flow, which will kill all the processes in the child process group.
This patch also fixes a typo.

[ Upstream commit fe06fe860250a4f01d0eaf70a2563b1997174a74 ]
The tm-resched-dscr test has started failing sometimes, depending on
what compiler it's built with, eg:
test: tm_resched_dscr
Check DSCR TM context switch: tm-resched-dscr: tm-resched-dscr.c:76: test_body: Assertion `rv' failed.
!! child died by signal 6
When it fails we see that the compiler doesn't initialise rv to 1 before
entering the inline asm block. Although that's counter intuitive, it
is allowed because we tell the compiler that the inline asm will write
to rv (using "=r"), meaning the original value is irrelevant.
Marking it as a read/write parameter would presumably work, but it seems
simpler to fix it by setting the initial value of rv in the inline asm.

[ Upstream commit 2adfa4210f8f35cdfb4e08318cc06b99752964c2 ]
The 'configinit.sh' script checks the format of optional argument for the
build directory, printing an error message if the format is not valid.
However, the error message uses the wrong variable, indicating an empty
string even though the user entered a non-empty (but erroneous) string.
This commit fixes the script to use the correct variable.

[ Upstream commit ed8b0de5a33d2a2557dce7f9429dca8cb5bc5879 ]
"rm -rf" is bricking some peoples' laptops because of variables being
used to store non-reinitializable firmware driver data that's required
to POST the hardware.
These are 100% bugs, and they need to be fixed, but in the mean time it
shouldn't be easy to *accidentally* brick machines.
We have to have delete working, and picking which variables do and don't
work for deletion is quite intractable, so instead make everything
immutable by default (except for a whitelist), and make tools that
aren't quite so broad-spectrum unset the immutable flag.

commit 9972fc0b859e7aaeb6d2d33bdb591959d9a436c0 upstream.
Commit 6071c22e1755 "ktest: Rewrite the config-bisect to actually work"
fixed the config-bisect to work nicely but in doing so it broke
make_min_config by changing the way assign_configs works.
The assign_configs function now adds the config to the hash even if
it is disabled, but changes the hash value to be that of the
line "# CONFIG_FOO is not set". Unfortunately, the make_min_config
test only checks to see if the config is removed. It now needs to
check if the config is in the hash and not set to be disabled.

commit 4a44a19b470a886997d6647a77bb3e38dcbfa8c5 upstream.
- MNT_NODEV should be irrelevant except when reading back mount flags,
no longer specify MNT_NODEV on remount.
- Test MNT_NODEV on devpts where it is meaningful even for unprivileged mounts.
- Add a test to verify that remount of a prexisting mount with the same flags
is allowed and does not change those flags.
- Cleanup up the definitions of MS_REC, MS_RELATIME, MS_STRICTATIME that are used
when the code is built in an environment without them.
- Correct the test error messages when tests fail. There were not 5 tests
that tested MS_RELATIME.

ftracetest: Take the first debugfs mount found
|
|
Running ftracetests on a box that mounted debugfs in two locations
made the ftracetests fail. This is because the tests uses a grep
of debugfs from the /proc/mounts file to find the debugfs mount
point, and then appends "/tracing" to that string to get the tracing
directory.
If the debugfs directory is mounted twice, then that grep will return
two answers and appending "/tracing" to a string with two lines will
not work.

Add two selftest scripts which tests kprobe-tracer as the startup
selftest does.
These test cases are testing that the kprobe_event can accept a
kprobe event with $stack related arguments and a kretprobe event
with $retval argument.

If git bisect reply is being used in the bisect tests, don't bother
doing the git bisect good or git bisect bad calls. The git bisect
reply will override them anyway, and that's called immediately
after the other two. Going the git bisect (good|bad) is just a
waste of time.

The reboot function when rebooting back to a good kernel has a check
to make sure that a new kernel was indeed booted. But that check
uses a timeout value, which when calling the monitor will still
return success if the timeout is hit (no bug was found). It should
return an error to let the reboot code know that a new kernel was
not reached. Only the reboot code checks the return value of the
monitor.

Add XFAIL and POSIX 1003.3 standard codes (UNRESOLVED/
UNTESTED/UNSUPPORTED) as result codes. These are used for the
results that test case is expected to fail or unsupported
feature (by config).
To return these result code, this introduces exit_unresolved,
exit_untested, exit_unsupported and exit_xfail functions,
which use real-time signals to notify the result code to
ftracetest.
This also set "errexit" option for the testcases, so that
the tests don't need to exit explicitly.
Note that if the test returns UNRESOLVED/UNSUPPORTED/FAIL,
its test log including executed commands is shown on console
and main logfile as below.

Add a "rw_lock" torture test to stress kernel rwlocks and their irq
variant. Reader critical regions are 5x longer than writers. As such
a similar ratio of lock acquisitions is seen in the statistics. In the
case of massive contention, both hold the lock for 1/10 of a second.

ftracetest is a collection of testcase shell-scripts for ftrace.
To avoid regressions of ftrace, these testcases check correct
ftrace behaviors. If someone would like to add any features on
ftrace, the patch series should have at least one testcase for
checking the new behavior.

When doing a manual bisect, a build can fail or a test can be inconclusive.
In these cases it would be helpful to be able to skip the test entirely.

rcu-tasks.2014.09.10a: Add RCU-tasks flavor of RCU.
|

Although the test cases have been added, they must be specified explicitly
via the kvm.sh --configs argument in order to run them. This commit
therefore adds the RCU-tasks tests to the CFLIST so that they will be
run automatically by default.
