Hi again EXT4 ML!
Here's a mail that would be sent as a result of an autoselection. It
will note the "score" of the patch, and will run the same tests we
do for patches tagged for stable.
As before, please let me know your thoughts on this. Thanks!

Hi EXT4 ML!
I'm working on a project to perform automatic patch selection for
stable, and automate the testing being done for patches going in
various stable tree.
I got some input from the XFS folks so far, and wanted to get some
input from the EXT4 folks as well.
Below is a mail that would be sent as a response for ext4 patches
tagged for stable and sent to the mailing list. Since this one is
already tagged for stable, these results should be useful for people
to understand if the patch properly applies to various stable trees
and passes testing.
For EXT4, at this point testing is the xfstests tree at
https://github.com/tytso/xfstests , running with "./check -g auto".
Complete build and test logs are available in the links embedded in
the mail.
I'd be happy to get feedback for this. Thanks!

When remounting ext4 from ro to rw, currently it allows its transition,
even if ext4_commit_super() returns EIO. Even worse thing is, after that,
fs/buffer complains buffer dirty bits like:

Ok, I introduced noop_direct_IO() in "fs, dax: prepare for
dax-specific address_space_operations", and cleaned up xfs, ext4, and
ext2 accordingly. Let me know if you want to see a resend of the
series with those changes. Otherwise this will appear in -next

* [PATCH] ext4: limit xattr size to INT_MAX
From: Theodore Ts'o @ 2018-03-29 21:46 UTC (permalink / raw)
To: Ext4 Developers List
Cc: adilger, ebiggers3, wen.xu, ebiggers, Theodore Ts'o, stable
In-Reply-To: <20180329194125.GC3790@thunk.org>
From: Eric Biggers <ebiggers@google.com>
ext4 isn't validating the sizes of xattrs. This is problematic
because ->e_value_size is a u32, but ext4_xattr_get() returns an int.
A very large size is misinterpreted as an error code, which
ext4_get_acl() translates into a bogus ERR_PTR() for which IS_ERR()
returns false, causing a crash.
Fix this by validating that all xattrs are <= INT_MAX bytes. Also add
explicit checks in ext4_xattr_block_get() and ext4_xattr_ibody_get()
just in case the xattr block is corrupted in memory.
This issue has been assigned CVE-2018-1095.

ext4: add better range checking for e_value_size in xattrs

broke a longstanding assumption by SELinux that it could call getxattr with a NULL buffer and 0 size to probe whether the filesystem supports the security xattrs at mount time.
Options for fixing:
- Revert or revise that patch to not return -ERANGE if buffer is NULL (prior behavior),
- Change SELinux sb_finish_set_opts() to treat -ERANGE as a non-error result.

In fact a common noop_direct_IO might make sense.

* linux-next 20180327 - "SELinux: (dev dm-3, type ext4) getxattr errno 34"
From: valdis.kletnieks @ 2018-03-29 17:57 UTC (permalink / raw)
To: Stephen Smalley, Theodore Ts'o; +Cc: linux-kernel, selinux, linux-ext4
[-- Attachment #1: Type: text/plain, Size: 99716 bytes --]
Seeing this error trying to mount ext4 disks. next-20180320 was OK.
SELinux: (dev dm-3, type ext4) getxattr errno 34
and for /var, it refused to mount entirely (which brought the boot
process to a screeching halt).
git log shows commits in the past few days against both selinux and ext4,
but nothing obvious.
This ring any bells, or is it time to start bisecting?
dmesg follows...

So ext4_direct_IO() for IS_DAX() files will just bail out. So could you
just provide ext4_dax_direct_IO() which will bail out and use it here? With
a similar comment as in xfs_vm_direct_IO() that open still needs this
method set... Thanks!

That warning implies a write ordering problem - there's a write with
an LSN on disk that does not yet exist in the log. i.e. the last FUA
write to the log had 1:63 in it, yet there's metadata on disk that
could only be *issued* after a REQ_FLUSH|REQ_FUA log write with
1:396 in it was *completed*. If we've only replayed up to the
FUA write with 1:63 in it, then no metadata writes should have been
*issued* with 1:396 in it as the LSN that is stamped into metadata
is only updated on log IO completion....
On first glance, this implies a bug in the underlying device write
replay code....
Cheers,
Dave.

This makes sense.

10min might be a bit long, 5min would be good enough. I may need to
adjust the fsstress "-n" param based on test results when I got some
time, hopefully this week..
And I noticed that fsstress "-p" is based on nr_cpus, I'd like to cap it
with a max allowed number, so test won't run for too long on hosts with
hundreds of cpus. It could always be scaled with _scale_fsstress_args.
+nr_cpus=$("$here/src/feature" -o)
+fsstress_args=$(_scale_fsstress_args -w -d $SCRATCH_MNT -n 512 -p $nr_cpus \
+ $FSSTRESS_AVOID)

The only fs which can pass the test right now is btrfs, so other

I'd say from current status, if XFS doesn't fail, it would definitely
finish in 10min.
For EXT4 I'm not pretty sure.
I'd like to keep current test case as simple as possible right now, and
for later enhancement, I have several different ideas:
1) Reflink fs + loopback
Yep, use btrfs/xfs as base filesystem and create copy using reflink,
then use such files as loopback device.
The good thing is, AFAIK btrfs/xfs reflink is really fast.
Much much faster than dm-snapshot or even LVM thin.
The much much smaller block size (4K default) makes CoW overhead
(LVM thin is 64K, not sure about dm-snapshot though).
The problem is, such setup needs extra mount point and can be a
little hard to setup, and we're introducing another layer of fs,
if the fs itself has some hidden bug, it would screw up the test
case.
2) LVM thin provision
LVM thin provision looks much like btrfs/xfs for block level, and
smaller default block size (64K vs original 2M) makes CoW overhead
smaller.
I'm currently testing this method, the good thing is it's a little
easier to setup and we can use single mount point.
Anyway, with proper and efficient snapshot ability implemented, I will
definitely convert this test case, and add Flush test case.
Thanks for your review too,

Hmm, how much time would the total test would take if you don't fail
it on fsck? I am asking because it may be possible to improve this with
only a single snapshot after mkfs.
Anyway, if total test run time is expected to be under 10min I wouldn't
bother with this optimization, at least not right now. IMO it is more
important to get the test out there to get the corruption bugs floating.
Thanks for working on this!

* [PATCH v2 3/3] fstests: generic: Check the fs after each FUA writes
From: Qu Wenruo @ 2018-03-28 4:40 UTC (permalink / raw)
To: linux-btrfs, fstests; +Cc: amir73il, linux-xfs, linux-ext4
In-Reply-To: <20180328044023.22078-1-wqu@suse.com>
Basic test case which triggers fsstress with dm-log-writes, and then
check the fs after each FUA writes.
With needed infrastructure and special handlers for journal based fs.
Signed-off-by: Qu Wenruo <wqu@suse.com>
---
changelog:
v2:
Use proper "SUSE Linux Products GmbH" instead of "SuSE"
Get rid of dm-snapshot which is pretty slow if we're creating and
deleting snapshots repeatedly.
(Maybe LVM thin provision would be much better, but current replay
solution is good so far, and no slower than dm-snapshot)
Add back run_check so that we can get the seed.
---
Unfortunately, neither xfs nor ext4 survies this test for even single
success, while btrfs survives.
(Although not what I want, I'm just trying my luck
to reproduce a serious btrfs corruption situation)
Although btrfs may be the fastest fs for the test, since it has fixed
small amount of write in mkfs and almost nothing to replay, it still
takes about 240s~300s to finish (the same level using snapshot).
It would take longer time for ext4 for its large amount of write during
mkfs, if it can survive the test in the first space.
As a comparison, btrfs takes about 5 seconds to replay log, mount,
unmount and run fsck at the end of the test.
But for ext4, it already takes about 5 seconds to do the same thing
before triggering fsck error.
Fsck fail for ext4:
_check_generic_filesystem: filesystem on /dev/mapper/test-scratch1 is inconsistent
*** fsck.ext4 output ***
fsck from util-linux 2.31.1
e2fsck 1.43.8 (1-Jan-2018)
Pass 1: Checking inodes, blocks, and sizes
Inode 131076 extent tree (at level 1) could be shorter. Fix? no
Inode 131262, i_size is 0, should be 258048. Fix? no
Pass 2: Checking directory structure
Pass 3: Checking directory connectivity
Pass 4: Checking reference counts
Pass 5: Checking group summary information
For xfs:
_check_xfs_filesystem: filesystem on /dev/mapper/test-scratch1 is inconsistent (r)
*** xfs_repair -n output ***
Phase 1 - find and verify superblock...
Phase 2 - using internal log
- zero log...
- scan filesystem freespace and inode maps...
- found root inode chunk
Phase 3 - for each AG...
- scan (but don't clear) agi unlinked lists...
- process known inodes and perform inode discovery...
- agno = 0
- agno = 1
- agno = 2
bad symlink header ino 8409190, file block 0, disk block 1051147
problem with symbolic link in inode 8409190
would have cleared inode 8409190
- agno = 3
- process newly discovered inodes...

- check for inodes claiming duplicate blocks...
- agno = 0
- agno = 1
- agno = 3
- agno = 2
entry "lb" in shortform directory 8409188 references free inode 8409190
would have junked entry "lb" in directory inode 8409188
bad symlink header ino 8409190, file block 0, disk block 1051147
problem with symbolic link in inode 8409190
would have cleared inode 8409190
No modify flag set, skipping phase 5
Phase 6 - check inode connectivity...
- traversing filesystem ...
entry "lb" in shortform directory inode 8409188 points to free inode 8409190
would junk entry
- traversal finished ...
- moving disconnected inodes to lost+found ...
Phase 7 - verify link counts...
Maximum metadata LSN (1:396) is ahead of log (1:63).
Would format log to cycle 4.
No modify flag set, skipping filesystem flush and exiting.
And special note for XFS guys, I also hit an XFS internal metadata
warning during journal replay:

* [PATCH 2/2] ext4: don't allow r/w mounts if metadata blocks overlap the superblock
From: Theodore Ts'o @ 2018-03-26 4:49 UTC (permalink / raw)
To: Ext4 Developers List; +Cc: Theodore Ts'o, stable
In-Reply-To: <20180326044906.13286-1-tytso@mit.edu>
If some metadata block, such as an allocation bitmap, overlaps the
superblock, it's very likely that if the file system is mounted
read/write, the results will not be pretty. So disallow r/w mounts
for file systems corrupted in this particular way.

* [PATCH 1/2] ext4: always initialize the crc32c checksum driver
From: Theodore Ts'o @ 2018-03-26 4:49 UTC (permalink / raw)
To: Ext4 Developers List; +Cc: Theodore Ts'o, stable
The extended attribute code now uses the crc32c checksum for hashing
purposes, so we should just always always initialize it. We also want
to prevent NULL pointer dereferences if one of the metadata checksum
features is enabled after the file sytsem is originally mounted.

* [PATCH] ext4: fail ext4_iget for root directory if unallocated
From: Theodore Ts'o @ 2018-03-26 1:48 UTC (permalink / raw)
To: Ext4 Developers List; +Cc: Theodore Ts'o, stable
If the root directory has an i_links_count of zero, then when the file
system is mounted, then when ext4_fill_super() notices the problem and
tries to call iput() the root directory in the error return path,
ext4_evict_inode() will try to free the inode on disk, before all of
the file system structures are set up, and this will result in an OOPS
caused by a NULL pointer dereference.
