[PATCH v2 0/6] Various test fixes proposed by Thomas Schmitt

[Glenn Washburn]

Thomas Schmitt proposed variations on these fixes[1]. I've broken his
patch into several patches with improvements.

Glenn

[1] https://lore.kernel.org/all/9956308756800479343@scdbackup.webframe.org/

v2:
 * Add patch #2 to allow grub-shell-luks-tester to cleanup properly on expected
   failure.
 * Add patch #5 to remove empty directories left by the cryptomount tests.

Glenn Washburn (5):
  tests/util/grub-shell-luks-tester: Add missing line to create RET
    variable in cleanup
  tests: Cleanup generated files on expected failure in
    grub_cmd_cryptomount
  tests/grub_cmd_cryptomount: Cleanup the cryptsetup script unless debug
    is enabled
  tests/grub_cmd_cryptomount: Default TMPDIR to /tmp
  tests/util/grub-shell: Remove the work directory on successful run and
    debug is not on

Thomas Schmitt (1):
  tests/grub_cmd_cryptomount: Remove temporary directories if successful
    and debug is not on

[PATCH v2 1/6] tests/util/grub-shell-luks-tester: Add missing line to create RET variable in cleanup

[Glenn Washburn]

Set the RET variable to the exit status of the script, as was assumed in the
cleanup() function.

[PATCH v2 2/6] tests: Cleanup generated files on expected failure in grub_cmd_cryptomount

[Glenn Washburn]

grub-shell-luks-tester only cleans up generated files when the test it
runs returns success. Sometimes tests are run that should fail. Add a
--xfail argument to grub-shell-luks-tester and pass it from
grub_cmd_cryptomount when invoking a test that is expected to fail.

This fixes behavior where grub_cmd_cryptomount temporary files, which are

[PATCH v2 5/6] tests/grub_cmd_cryptomount: Remove temporary directories if successful and debug is not on

[Glenn Washburn]

From: Thomas Schmitt <scdbackup@gmx.net>

grub_cmd_cryptomount creates a directory per subtest. If a subtest is
successful and debugging is not on, the directory should be empty. So it
can be deleted.

Re: [PATCH v2 0/6] Various test fixes proposed by Thomas Schmitt

[Thomas Schmitt via Grub-devel]

Hi,

Tested-by: Thomas Schmitt <scdbackup@gmx.net>

with remaining unrelated problems.

-----------------------------------------------------------------------
Test details:

The patch series applied by "git am" without problems to a branch cloned
from freshly pulled "master".

  make check TESTS=grub_cmd_cryptomount

produces

  # PASS:  1

No remaining files from that run are to see in / and /tmp.
During the "make check" i could see files appear and vanish in /tmp.


Then i ran the full "make check" (which lasts really long on a 4 GHz
Xeon with "top" reporting the system being mostly idle).

These failures did not happen in june 2024, when i ran "make check":

  FAIL: ntfs_test
  FAIL: zfs_test

Other failures which i already had in 2024 are:

  FAIL: hfs_test
  FAIL: luks1_test
  FAIL: luks2_test
  FAIL: grub_func_test

Some tests which failed in 2024 but don't any more:
  PASS: erofs_test
  PASS: exfat_test

(My mail in june 2024 with the list of test failures was
 Date: Thu, 20 Jun 2024 22:05:02 +0200
 Message-Id: <20240620200504.466683-1-scdbackup@gmx.net>
Regrettably http://lists.gnu.org/mailman/listinfo/grub-devel does not
work for me today. So i cannot give a link into the archive.)

Files which remained in /tmp:

  grub-fs-tester.20250304100244880329310.ntfs.JrW
  grub-fs-tester.20250304100732808627445.vfat12.AKi
  grub-fs-tester.20250304102111753946043.zfs_zstd.HeI
  grub-fs-tester.20250304102132560362937.luks1.szH
  grub-fs-tester.20250304102140126776818.luks2.eTV
  tmp.3t4AGcksU8
  tmp.5ch8QxZT6p
  tmp.6msLyaqLuq
  tmp.CeFRqmCNlf
  tmp.m60l7N0wuj

tmp.CeFRqmCNlf looks like a GRUB configuration.
tmp.m60l7N0wuj looks like the result of GRUB's "ls" command, possibly
with a grub-mkrescue ISO in (cd0).
The contents of the others give me no clue.


----------------------------------------------------------------------

I also reviewed the patches.
(Give me a note if i shall add the tags by single mails to the patch
mails.)

This was introduced by the security fixes and there's a patch on the
list to fix this.

I've not looked into this, but I'm seeing it fail too.

This should fail on anything but now ancient debian systems. This is
due to the package having a custom patch that added functionality and
now doesn't, IIRC.

These should not be failing.

This is expected, and will be for the foreseeable future, unfortunately.
