* [PATCH v7 0/1] xfstests: add log attribute replay test @ 2022-02-23 3:37 Catherine Hoang 2022-02-23 3:37 ` [PATCH v7 1/1] xfstests: Add Log Attribute Replay test Catherine Hoang 0 siblings, 1 reply; 15+ messages in thread From: Catherine Hoang @ 2022-02-23 3:37 UTC (permalink / raw) To: linux-xfs, fstests Hi all, This patch aims to provide better test coverage for Allison’s delayed attribute set. These tests aim to cover cases where attributes are added, removed, and overwritten in each format (shortform, leaf, node). Error inject is used to replay these operations from the log. The following cases are covered in this test: - empty, add/remove inline attr (64 bytes) - empty, add/remove internal attr (1kB) - empty, add/remove remote attr (64kB) - inline, add/remove inline attr (64 bytes) - inline, add/remove internal attr (1kB) - inline, add/remove remote attr (64kB) - extent, add/remove internal attr (1kB) - extent, add multiple internal attr (inject error on split operation) - extent, add multiple internal attr (inject error on transition to node) - extent, add/remove remote attr (64kB) - btree, add/remove multiple internal (1kB) - btree, add/remove remote attr (64kB) - overwrite shortform attr - overwrite leaf attr - overwrite node attr Running these tests require the corresponding kernel and xfsprogs changes that add the new error tags da_leaf_split and attr_leaf_to_node. v6->v7: - Rename larp_leaf_to_node to attr_leaf_to_node - Check that the larp knob is writable - Cleanup files that were created during testing Suggestions and feedback are appreciated!

We'll need to get the kernel/user space features merged before the test can run though. It seems Darrick has found a bug in generic/467, so we'll need to get that weeded out before the rest can follow. We'll chat more in our meeting today. In the meantime, I encourgage reviews for the testcase since we will eventually need it. Thanks all!

This will turn off LARP unconditionally, so after this runs nothing will exercise the LARP paths, even if that's what I want the tests to do. Also, this does not replicate what the generic _cleanup() function does. Also, no need to remove $testdir - it's on the scratch device. Also, don't call things "testdir" because "test directory" has specific meaning - i.e. the *test device mount* - and this is too easy to confuse when reading the test code. > +} > + > +test_attr_replay() > +{ > + testfile=$testdir/$1 > + attr_name=$2 > + attr_value=$3 > + flag=$4 > + error_tag=$5 > + > + # Inject error > + _scratch_inject_error $error_tag > + > + # Set attribute > + echo "$attr_value" | ${ATTR_PROG} -$flag "$attr_name" $testfile 2>&1 | \ > + _filter_scratch > + > + # FS should be shut down, touch will fail > + touch $testfile 2>&1 | _filter_scratch > + > + # Remount to replay log > + _scratch_remount_dump_log >> $seqres.full > + > + # FS should be online, touch should succeed > + touch $testfile > + > + # Verify attr recovery > + { $ATTR_PROG -g $attr_name $testfile | md5sum; } 2>&1 | _filter_scratch > + > + echo "" > +} > + > +create_test_file() > +{ > + filename=$testdir/$1 > + count=$2 > + attr_value=$3 > + > + touch $filename > + > + for i in `seq $count` > + do > + $ATTR_PROG -s "attr_name$i" -V $attr_value $filename >> \ > + $seqres.full > + done > +} > + > +# real QA test starts here > +_supported_fs xfs > + > +_require_scratch > +_require_attrs > +_require_xfs_io_error_injection "larp" > +_require_xfs_io_error_injection "da_leaf_split" > +_require_xfs_io_error_injection "attr_leaf_to_node" > +_require_xfs_sysfs debug/larp These go first, before any code. > +test -w /sys/fs/xfs/debug/larp || _notrun "larp knob not writable" When is the sysfs not writeable? > +# turn on log attributes > +echo 1 > /sys/fs/xfs/debug/larp Needs to store the previous value so it can be restored at cleanup. > +attr16="0123456789ABCDEF" > +attr64="$attr16$attr16$attr16$attr16" > +attr256="$attr64$attr64$attr64$attr64" > +attr1k="$attr256$attr256$attr256$attr256" > +attr4k="$attr1k$attr1k$attr1k$attr1k" > +attr8k="$attr4k$attr4k" > +attr16k="$attr8k$attr8k" > +attr32k="$attr16k$attr16k" > +attr64k="$attr32k$attr32k" > + > +echo "*** mkfs" > +_scratch_mkfs >/dev/null > + > +echo "*** mount FS" > +_scratch_mount There's no need for echo lines like this in the golden output - it's obvious what failed from the diff... > +testdir=$SCRATCH_MNT/testdir > +mkdir $testdir Why not just use $SCRATCH_MNT directly? > + > +# empty, inline > +create_test_file empty_file1 0 > +test_attr_replay empty_file1 "attr_name" $attr64 "s" "larp" > +test_attr_replay empty_file1 "attr_name" $attr64 "r" "larp" > + > +# empty, internal > +create_test_file empty_file2 0 > +test_attr_replay empty_file2 "attr_name" $attr1k "s" "larp" > +test_attr_replay empty_file2 "attr_name" $attr1k "r" "larp" > + > +# empty, remote > +create_test_file empty_file3 0 > +test_attr_replay empty_file3 "attr_name" $attr64k "s" "larp" > +test_attr_replay empty_file3 "attr_name" $attr64k "r" "larp" single attr insert/remove.

* [PATCH] xfs/larp: Make test failures debuggable 2022-02-23 3:37 ` [PATCH v7 1/1] xfstests: Add Log Attribute Replay test Catherine Hoang 2022-03-01 20:46 ` Allison Henderson 2022-05-05 23:54 ` Dave Chinner @ 2022-05-06 7:51 ` Dave Chinner 2022-05-06 16:14 ` Darrick J. Wong ` (2 more replies) 2 siblings, 3 replies; 15+ messages in thread From: Dave Chinner @ 2022-05-06 7:51 UTC (permalink / raw) To: Catherine Hoang; +Cc: linux-xfs, fstests From: Dave Chinner <dchinner@redhat.com> Md5sum output for attributes created combined program output and attribute values. This adds variable path names to the md5sum, so there's no way to tell if the md5sum is actually correct for the given attribute value that is returned as it's not constant from test to test. Hence we can't actually say that the output is correct because we can't reproduce exactly what we are hashing easily. Indeed, the last attr test in series (node w/ replace) had an invalid md5sum. The attr value being produced after recovery was correct, but the md5sum output match was failing. Golden output appears to be wrong. Fix this issue by seperately dumping all the attributes on the inode via a list operation to indicate their size, then dump the value of the test attribute directly to md5sum. This means the md5sum for the attributes using the same fixed values are all identical, so it's easy to tell if the md5sum for a given test is correct. We also check that all attributes that should be present after recovery are still there (e.g. checks recovery didn't trash innocent bystanders). Further, the attribute replace tests replace an attribute with an identical value, hence there is no way to tell if recovery has resulted in the original being left behind or the new attribute being fully recovered because both have the same name and value. When replacing the attribute value, use a different sized value so it is trivial to determine that we've recovered the new attribute value correctly. Also, the test runs on the scratch device - there is no need to remove the testdir in _cleanup. Doing so prevents post-mortem failure analysis because it burns the dead, broken corpse to ash and leaves no way of to determine cause of death. Signed-off-by: Dave Chinner <dchinner@redhat.com> --- Hi Catherine, These are all the mods I needed to make to be able to understand the test failures I was getting as I debugged the new LARP recovery algorithm I've written. You'll need to massage the test number in this patch to apply it on top of your patch. I haven't added any new test cases yet, nor have I done anything to manage the larp sysfs knob, but we'll need to do those in the near future. Zorro, can you consider merging this test in the near future? We're right at the point of merging the upstream kernel code and so really need to start growing the test coverage of this feature, and this test should simply not-run on kernels that don't have the feature enabled....

Please save the old value, then write it back in the _cleanup function. <slightly ot rant> These sysfs knobs are a pain because they all reset to defaults if xfs.ko gets cycled. I know, I know, at least Dave and Ted don't do modular kernels and so never see this happen, but I do. I bet Dave also hasn't ever run xfs/434 or xfs/436, which might be why I'm the only one seeing dquot leaks with 5.19-next. (I might be able to lift the xfs-as-module requirement if "echo 1 > /sys/kernel/slab/*/validate" does what I think it might, since all we want to do is look for slab leaks, and those tests rmmod/modprobe as a brute force way of making the slab debug code check for leaks.) In case anyone's wondering, a solution to the knobs getting unset after an rmmod/modprobe cycle is to add a file /etc/udev/rules.d/99-fstester.rules containing: ACTION=="add|change", SUBSYSTEM=="module", DEVPATH=="/module/${module}", RUN+="/bin/sh -c \"echo ${value} > ${knob}\"" which should be enough to keep LARP turned on. <end rant> Anyway, since this is a proposed test, I say that with this applied and the debug knob bits fixed, the whole thing is Reviewed-by: Darrick J.

Ok, I'm going to do that when I merge it, if Catherine wouldn't like to do more changes in a V8 patch. If this case still need more changes, please tell me in time, and then it might have to wait the fstests release after next, if too late.

Great, that would be really helpful if you'd like to rebase this patch to fstests for-next branch. And how about combine Dave's patch with your patch? I don't think it's worth merging two seperated patches for one signle new case. What does Dave think? I just merged below two patchset[1] into xfs-5.18-fixes-1, then tried to test this case (with you and Dave's patch). But it always failed as [2]. Please make sure it works as expected with those kernel patches still reviewing, I can't be sure I have the testing environment to guarantee that. Or I'd like to push this case after I see its target kernel patchset be merged by xfs-linux at first.

I don't want random changes added to the test on commit right now as I'm still actively working on it. I've said twice now that this needs fixing (3 if you count this mention) and that the test coverage also needs improving.

That doesn't mean it can't be merged. It is a pain for mulitple people to collaborate on a test that isn't merged because the test number is not set in stone and chosing numbers always conflicts with other tests under development. Getting the test merged early makes knocking all the problems out of the test (and the code it is testing!) much, much easier. > Great, that would be really helpful if you'd like to rebase this patch to fstests > for-next branch.

You built a broken kernel as it has none of the dependencies and bug fixes that had already been committed to for-next for the new functionality to work correctly. I posted a V3 patchset last night and a published a git branch with all the kernel changes that you can use for testing if you want. > Please make sure it works > as expected with those kernel patches still reviewing, I did - the failures you see are expected from what you were testing. i.e. the test ran just fine, the kernel code you were running is buggy and you didn't update xfsprogs so logprint supported the new log types, hence the test (correctly) reported failures.

Oh, I thought you're hurry to hope this test be merged, so I tried to help it to catch the fstests release of this Sunday. If it's not such hurry, let's back to the regular review workflow, I'll merge this test case *immediately* when I saw a clear RVB on it from you. Then it'll catch the latest fstests release after that (not guarantee this weekend). Hope that help.

Yes, I know about this. I haven't done anything about it yet because I haven't decided yet whether it should stay or be removed. Getting the test and the code it tests working has been my focus so far. I have a wrapper script that sets the knob for the entire of the fstests run (i.e. so all attr and recovery tests exercise the LARP functionality) and so I'm not sure that this test should twiddle the knob at all. i.e. right now it would be more useful to me for the test to check if the knob is not set to just _not_run the test, rather than turn it on and off and all that... Indeed, we probably shouldn't be forcing everyone to test a brand new experimental feature that might be unstable and cause the test run to halt prematurely (e.g. because it crashes). > <slightly ot rant> > > These sysfs knobs are a pain because they all reset to defaults if > xfs.ko gets cycled. I know, I know, at least Dave and Ted don't do > modular kernels and so never see this happen, but I do. sysfs knobs get reset by reboots to load a new kernel, so the impact is identical - I have to reset the knob every time I load a new test kernel, just like you have to reset it every time you load a new module. > I bet Dave also > hasn't ever run xfs/434 or xfs/436, which might be why I'm the only one > seeing dquot leaks with 5.19-next. Yup, there are a bunch of tests that I never run because: - scsi_debug requires modular kernel - I always build with fatal XFS ASSERTs, so the tests that want non-fatal asserts don't run - xfs/43[4-6] require a modular kernel - xfs/490 requires CONFIG_XFS_DEBUG be turned off (I *never* do that) - I generally don't have source code on my test machines, so api-violations.sh won't run (xfs/437) And there's probably a few more in that list as well. IMO, any test that depends on a specific debug config or test environment setup that aren't (or can't be) consistently used by the entire developer base should be discouraged precisely because it means different developers end up with different code coverage and might miss problems they really should know about. > (I might be able to lift the xfs-as-module requirement if "echo 1 > > /sys/kernel/slab/*/validate" does what I think it might, since all we > want to do is look for slab leaks, and those tests rmmod/modprobe as a > brute force way of making the slab debug code check for leaks.)

I don't want it turned on unconditionally - I have to test both the existing code path and the new LARP code path, so I'm constantly toggling the value between test runs. > Anyway, since this is a proposed test, I say that with this applied and > the debug knob bits fixed, the whole thing is > Reviewed-by: Darrick J.

Sure, due to LSF meeting, we have few of reviewed patches this week. I'll merge Catherine's "[PATCH v7 1/1] xfstests: Add Log Attribute Replay test"(with your RVB) into fstests for-next branch at first, then this patch ensued. I'll push it this weekend, after my basic testing pass. If you'd like to combine this patch with Catherine's patch into one patch, or you have more review points, feel free to tell me.
