ktest: Fix child exit code processing

2017-03-13T20:40:47+00:00

commit 32677207dcc5e594254b7fb4fb2352b1755b1d5b upstream.

The child_exit errno needs to be shifted by 8 bits to compare against the
return values for the bisect variables.

selftests: do not require bash to run netsocktests testcase

2017-01-26T16:40:33+00:00

commit 3659f98b5375d195f1870c3e508fe51e52206839 upstream.

Nothing in this minimal script seems to require bash. We often run these
tests on embedded devices where the only shell available is the busybox
ash. Use sh instead.

efi: Make efivarfs entries immutable by default

2016-03-14T22:10:35+00:00

commit ed8b0de5a33d2a2557dce7f9429dca8cb5bc5879 upstream.

"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.

userns: Unbreak the unprivileged remount tests

2015-01-07T16:55:15+00:00

commit db86da7cb76f797a1a8b445166a15cb922c6ff85 upstream.

A security fix in caused the way the unprivileged remount tests were
using user namespaces to break.  Tweak the way user namespaces are
being used so the test works again.

mnt: Update unprivileged remount test

2015-01-07T16:55:09+00:00

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.

mnt: Add tests for unprivileged remount cases that have found to be faulty

2014-09-17T14:55:10+00:00

commit db181ce011e3c033328608299cd6fac06ea50130 upstream.

Kenton Varda  discovered that by remounting a
read-only bind mount read-only in a user namespace the
MNT_LOCK_READONLY bit would be cleared, allowing an unprivileged user
to the remount a read-only mount read-write.

Upon review of the code in remount it was discovered that the code allowed
nosuid, noexec, and nodev to be cleared.  It was also discovered that
the code was allowing the per mount atime flags to be changed.

The first naive patch to fix these issues contained the flaw that using
default atime settings when remounting a filesystem could be disallowed.

To avoid this problems in the future add tests to ensure unprivileged
remounts are succeeding and failing at the appropriate times.

selftests: Add test of PMU instruction counting on powerpc

2013-08-14T04:57:10+00:00

This commit adds a test of instruction counting using the PMU on powerpc.

Although the bulk of the code is architecture agnostic, the code needs to
run a precisely sized loop which is implemented in assembler.

selftests: Add infrastructure for powerpc selftests

2013-08-14T04:57:03+00:00

This commit adds a powerpc subdirectory to tools/testing/selftests,
for tests that are powerpc specific.

On other architectures nothing is built. The makefile supports cross
compilation if the user sets ARCH and CROSS_COMPILE.
