      ftracetest: Add POSIX.3 standard and XFAIL result codes · 915de2ad
      由 Masami Hiramatsu 提交于 
      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.

      mnt: Add tests for unprivileged remount cases that have found to be faulty · db181ce0
      由 Eric W. Biederman 提交于 
      Kenton Varda <kenton@sandstorm.io> 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.

      tools/testing/selftests/sysctl: validate sysctl_writes_strict · 24fe831c
      由 Kees Cook 提交于 
      This adds several behavioral tests to sysctl string and number writing
to detect unexpected cases that behaved differently when the sysctl
kernel.sysctl_writes_strict != 1.
