Hi all, This is an unusually large set of bug fixes for fstests. The first 20 patches in this patchset are corrections for that RFC series. The most significant change is that I made ./check run each test with its own Unix process session id. This means that a test can use pkill to kill all of its own subprocesses, without killing anyone else's subprocesses. I'm not completely sold on that approach, but it works for me. It seems to work for check-parallel as well, though I've not tested that all that much. Note: I am /not/ happy about Dave's RFC going straight to for-next without even a complete review right before everyone went on PTO for several weeks for xmas/solar new year. But in the interests of getting QA back on line for myself and everyone else who's having problems, here it is. The last two patches are bugs that have lurked in fstests for ages. If you're going to start using this code, I strongly recommend pulling from my git trees, which are linked below. With a bit of luck, this should all go splendidly. Comments and questions are, as always, welcome. --D kernel git tree: https://git.kernel.org/cgit/linux/kernel/git/djwong/xfs-linux.git/log/?h=random-fixes xfsprogs git tree: https://git.kernel.org/cgit/linux/kernel/git/djwong/xfsprogs-dev.git/log/?h=random-fixes fstests git tree: https://git.kernel.org/cgit/linux/kernel/git/djwong/xfstests-dev.git/log/?h=random-fixes --- Commits in this patchset: * generic/476: fix fsstress process management * metadump: make non-local function variables more obvious * metadump: fix cleanup for v1 metadump testing * generic/482: _run_fsstress needs the test filesystem * generic/019: don't fail if fio crashes while shutting down * fuzzy: do not set _FSSTRESS_PID when exercising fsx * common/rc: create a wrapper for the su command * common: fix pkill by running test program in a separate session * unmount: resume logging of stdout and stderr for filtering * mkfs: don't hardcode log size * common/xfs: find loop devices for non-blockdevs passed to _prepare_for_eio_shutdown * preamble: fix missing _kill_fsstress * generic/650: revert SOAK DURATION changes * generic/032: fix pinned mount failure * fuzzy: stop __stress_scrub_fsx_loop if fsx fails * fuzzy: don't use readarray for xfsfind output * fuzzy: always stop the scrub fsstress loop on error * fuzzy: port fsx and fsstress loop to use --duration * common/rc: don't copy fsstress to $TEST_DIR * fix _require_scratch_duperemove ordering * fsstress: fix a memory leak * fsx: fix leaked log file pointer * build: initialize stack variables to zero by default --- check | 43 +++++++++++++++++++--- common/fuzzy | 95 ++++++++++++++++++++++++++++++++----------------- common/metadump | 42 ++++++++++------------ common/preamble | 2 + common/quota | 2 + common/rc | 93 +++++++++++++++++++++++++++++++++++++++++------- common/reflink | 6 ++- common/xfs | 6 +++ configure.ac | 1 + include/builddefs.in | 3 +- ltp/fsstress.c | 1 + ltp/fsx.c | 1 + m4/package_libcdev.m4 | 14 +++++++ src/xfsfind.c | 14 ++++++- tests/generic/019 | 2 + tests/generic/032 | 9 +++++ tests/generic/050 | 2 + tests/generic/085 | 2 + tests/generic/093 | 2 + tests/generic/125 | 2 + tests/generic/128 | 2 + tests/generic/193 | 36 +++++++++---------- tests/generic/230 | 14 ++++--- tests/generic/231 | 2 + tests/generic/233 | 2 + tests/generic/270 | 12 ++++-- tests/generic/310 | 6 ++- tests/generic/314 | 2 + tests/generic/327 | 2 + tests/generic/328 | 4 +- tests/generic/355 | 2 + tests/generic/361 | 4 +- tests/generic/453 | 6 ++- tests/generic/476 | 2 + tests/generic/514 | 2 + tests/generic/530 | 6 +-- tests/generic/531 | 6 +-- tests/generic/561 | 2 + tests/generic/573 | 2 + tests/generic/590 | 2 + tests/generic/600 | 2 + tests/generic/601 | 2 + tests/generic/603 | 10 +++-- tests/generic/650 | 5 +-- tests/generic/673 | 2 + tests/generic/674 | 2 + tests/generic/675 | 2 + tests/generic/680 | 2 + tests/generic/681 | 2 + tests/generic/682 | 2 + tests/generic/683 | 2 + tests/generic/684 | 2 + tests/generic/685 | 2 + tests/generic/686 | 2 + tests/generic/687 | 2 + tests/generic/688 | 2 + tests/generic/691 | 8 ++-- tests/generic/721 | 10 +++-- tests/generic/726 | 2 + tests/generic/727 | 2 + tests/generic/746 | 2 + tests/xfs/149 | 2 + tests/xfs/501 | 2 + tests/xfs/502 | 2 + tests/xfs/530 | 2 + tests/xfs/720 | 2 + tests/xfs/795 | 2 + tests/xfs/803 | 2 + 68 files changed, 347 insertions(+), 192 deletions(-)
