It turns out that there are some serious problems with the on-disk
format of journal checksum v2. The foremost is that the function to
calculate descriptor tag size returns sizes that are too big. This
causes alignment issues on some architectures and is compounded by the
fact that some parts of jbd2 use the structure size (incorrectly) to
determine the presence of a 64bit journal instead of checking the
feature flags. These errors regrettably lead to the journal
corruption reported by Mr. Reardon.
Therefore, introduce journal checksum v3, which enlarges the
descriptor block tag format to allow for full 32-bit checksums of
journal blocks, fix the journal tag function to return the correct
sizes, and fix the jbd2 recovery code to use feature flags to
determine 64bitness.
Add a few function helpers so we don't have to open-code quite so
many pieces.
Switching to a 16-byte block size was found to increase journal size
overhead by a maximum of 0.1%, to convert a 32-bit journal with no
checksumming to a 32-bit journal with checksum v3 enabled.

We don't want ext2fs_open2() to report bad sb checksum on something
that's not even an ext* superblock. This apparently happens pretty
easily if we try to open an XFS filesystem. Thus, make it so that a
bad magic number code always trumps the sb checksum error code.

If there aren't enough blocks in the FS to allocate all of the
hugefiles, return ENOSPC, not ENOMEM.

When creating a journal inode, check the return value from
block_iterate3() because otherwise we fail to capture errors such as
being unable to allocate an extent tree block, which leads to e2fsck
creating broken journals.

When we're removing the internal journal (broken journal, turning it
off, or adding an external journal), zero s_jnl_blocks so that they
can't be picked up by accident later.

Create a journal.c with routines adapted from e2fsck/journal.c to
handle opening and closing the journal, and setting up the
descriptors, and all that. Unlike e2fsck's versions which try to
identify and fix problems, the routines here have no way to repair
anything.
v2: Don't feed ext2_filsys state flags to the IO manager file open
routine. Fix a few bugs when handling external journal devices.

Please don't copy the .c files around. That just invites confusion
because git will show that there are new files, debugfs/recovery.c and
debugfs/revoke.c, and some future unwary developer might try to edit
recovery.c and revoke.c in the debugfs directory.
Much better to do it this way:
recovery.o: $(srcdir)/../e2fsck/recovery.c
$(E) " CC $@"
$(Q) $(CC) -c $(ALL_CFLAGS) -I$(srcdir) \
$(srcdir)/../e2fsck/recovery.c -DDEBUGFS -o $@
revoke.o: $(srcdir)/../e2fsck/revoke.c
$(E) " CC $@"
$(Q) $(CC) -c $(ALL_CFLAGS) -I$(srcdir) \
$(srcdir)/../e2fsck/revoke.c -DDEBUGFS -o $@
I'll fix this up when I apply this patch.
Cheers,
- Ted

Will that pick up debugfs/jfs_user.h, though? I originally tried it this way
but gcc seemed to want to pull in the jfs_user.h from e2fsck/.

Yeah, I figured that out shortly after I sent the message. The way I
fixed it was a bit more involved, but I think it's cleaner.
Long run, what I want to do is to rename libquota to libsupport, and
then move things like profile.c, recovery.c, revoke.c, etc. into that
single directory, and then harmonize all of the ugly hacks that we
have in various different versions of jfs_user.h. Given that, what I
did for now was to harmonize (as much as possible) debugfs/jfs_user.h
and e2fsck/jfs_user.h, and there is now a single version of jfs_user.h
in e2fsck. We still have some customizations based on -DDEBUGFS, but
we can clean that up later.

commit cdca03d363aabe8026a1b343d3035ea333117ffa

debugfs: create journal handling routines
Create a journal.c with routines adapted from e2fsck/journal.c to
handle opening and closing the journal, and setting up the
descriptors, and all that. Unlike e2fsck's versions which try to
identify and fix problems, the routines here have no way to repair
anything.

Probably not necessary to -DDEBUGFS twice here.

To: tytso, darrick.wong; +Cc: linux-ext4
The journal superblock's s_sequence field seems to track the tid of
the tail (oldest) transaction in the log. Therefore, when we release
the journal, set the s_sequence to the tail_sequence, because setting
it to the transaction_sequence means that we're setting the tid to
that of the head of the log. Granted, for replay these two are
usually the same (and s_start == 0 anyway) so thus far we've gotten
lucky and nobody noticed.

Thanks, applied.
(Actually, for e2fsck for replay it will always be the same because
the journal *must* be completely replaied cleared before the rest of
e2fsck can be allowed to proceed.)

Extend debugfs with the ability to create transactions and replay the
journal. This will eventually be used to test kernel recovery and
metadata_csum recovery.
v2: Find the FS context without using j_inode, since it won't always
be valid; allow user to specify external journal file; start writing
transactions at j_first.

Simple tests for the journal transaction creation code. We test
writing (bad) block bitmaps out through the journal and replaying them
via fsck, with a few twists:
(a) All bitmaps are committed (fs errors reported)
(b) All the bitmap blocks are revoked (no errors)
(c) The transaction is never committed (no errors)
(d) Same as (a), but debugfs gets to do the replay.
We also test:
(a) writing and replaying transactions with multiple
descriptor blocks
(b) same, but with multiple revoke blocks.
(c) adding the 64bit flag to a journal

Simple tests for the 64bit journal transaction creation code when
journal and metadata_csum are enabled. We test writing (bad) block
bitmaps out through the journal and replaying them via fsck, with a
few twists:
(a) All bitmaps are committed (fs errors reported)
(b) All the bitmap blocks are revoked (no errors)
(c) The transaction is never committed (no errors)
(d) Same as (a), but debugfs gets to do the replay.
We also test:
(a) writing and replaying transactions with multiple
descriptor blocks
(b) same, but with multiple revoke blocks.

Simple tests for the 32bit journal transaction creation code when
journal and metadata_csum are enabled. We test the following:
(a) writing and replaying transactions with multiple
descriptor blocks
(b) same, but with multiple revoke blocks.

To: tytso, darrick.wong; +Cc: linux-ext4
Test e2fsck' ability to deal with (a) corrupt descriptor block
checksum; (b) obviously bad journal block tid; and (c) corrupt journal
blocks. These should exercise the journal recovery infinite loop
bugfix earlier in this patchset.

NAK, this file is incorrect. As noted in a previous email, the revoke block
should itself be revoked (and the replay restarted) if we encounter corrupt
blocks.
Silly /me didn't consider that revoke records aren't intended to unilaterally
kill journal blocks; they only make sense if there's a subsequent transaction
also writing the block.

Yeah, everything but #21 is ok. I'll issue a new #21 shortly.
(and four other patches to fix other problems e2fuzz found along the way...)

Test e2fsck' ability to deal with (a) corrupt descriptor block
checksum; (b) obviously bad journal block tid; and (c) corrupt journal
blocks. These should exercise the journal recovery infinite loop
bugfix earlier in this patchset.
This test also ensures that (with metadata_csum and journal_csum_v3)
journal replay continues past a corrupt journal block.
v2: Update j_corrupt_journal_block after a clarification of what
revoke records actually do.

Add a readahead method for prefetching ranges of disk blocks. This is
useful for inode table scanning, and other large contiguous ranges of
blocks, and may also prove useful for random block prefetch, since it
will allow reordering of the IO without waiting synchronously for the
reads to complete.
It is currently using the posix_fadvise(POSIX_FADV_WILLNEED)
interface, as this proved most efficient during our testing.
[darrick.wong@oracle.com]
Make the arguments to the readahead function take the same ULL values
as the other IO functions, and return an appropriate error code when
fadvise isn't available.

Could you also plumb through the new method in test_io.c? Because we
often use this to interposed between mke2fs or e2fsprogs and unix_io.c
for debugging purposes.
Thanks!

To: tytso, darrick.wong; +Cc: linux-ext4
This patch adds to e2fsck the ability to pre-fetch metadata into the
page cache in the hopes of speeding up fsck runs. There are two new
functions -- the first allows a caller to readahead a list of blocks,
and the second is a helper function that uses that first mechanism to
load group data (bitmaps, inode tables).
These new e2fsck routines require the addition of a dblist API to
allow us to iterate a subset of a dblist. This will enable
incremental directory block readahead in e2fsck pass 2.
There's also a function to estimate the readahead given a FS.
v2: Add an API to create a dblist with a given number of list elements
pre-allocated. This enables us to save ~2ms per call to
e2fsck_readahead() (assuming a 2MB RA buffer) by not having to
repeatedly call ext2_resize_mem as we add blocks to the list.

To: tytso, darrick.wong; +Cc: linux-ext4
e2fsck pass1 is modified to use the block group data prefetch function
to try to fetch the inode tables into the pagecache before it is
needed. We iterate through the blockgroups until we have enough inode
tables that need reading such that we can issue readahead; then we sit
and wait until the last inode table block read of the last group to
start fetching the next bunch.
pass2 is modified to use the dirblock prefetching function to prefetch
the list of directory blocks that are assembled in pass1. We use the
"iterate a subset of a dblist" and avoid copying the dblist. Directory
blocks are fetched incrementally as we walk through the directory
block list. In previous iterations of this patch we would free the
directory blocks after processing, but the performance hit to e2fsck
itself wasn't worth it. Furthermore, it is anticipated that most
users will then mount the FS and start using the directories, so they
may as well remain in the page cache.
pass4 is modified to prefetch the block and inode bitmaps in
anticipation of pass 5, because pass4 is entirely CPU bound.
In general, these mechanisms can decrease fsck time by 10-40%, if the
host system has sufficient memory and the storage system can provide a
lot of IOPs. Pretty much any storage system capable of handling
multiple IOs in-flight at any time will see a fairly large performance
boost. (Single-issue USB mass storage disks seem to suffer badly.)
By default, the readahead buffer size will be set to the size of a block
group's inode table (which is 2MiB for a regular ext4 FS). The -E
readahead_kb= option can be given to specify the amount of memory to
use for readahead or zero to disable it entirely; or an option can be
given in e2fsck.conf.
v2: Fix an off-by-one error in the pass1 readahead which made the
readahead trigger one inode too late if the block groups are full.

It's really too bad that we are introducing a new journal checksum
feature, when the current journal checksum implementation is
essentially unusable. Any minor corruption in one transaction block
that has following un-checkpointed transactions will almost certainly
result in _more_ corruption of the filesystem rather than less, due
to all of the *committed* but uncheckpointed blocks being discarded
from the journal. This would also result in a silent rollback of
filesystem state and loss of user data if running with data=journal.
As a result, there is no practical value (IMHO) to enabling this
feature at all currently.
We've discussed in the past that having per-block checksums is
necessary in order to fix this, so that only corrupt blocks in the
journal are skipped during replay, and may not result in any visible
filesystem corruption if the blocks are overwritten later during
replay. Otherwise, this will itself result in yet a new block tag
format and journal checksum feature.
Is there any chance you could take a look at implementing this as
part of journal_checksum_v3 instead of fixing the current bugs only
to have a "correctly working" but not usable feature?
Cheers, Andreas

Journal checksum v2 implements this. The kernel skips the corrupt block,
continues the journal replay and refuses to mount, thereby forcing a fsck run.
fsck does the same, but it (obviously) runs a full check after the replay to
find anything other damage.
>From tests/j_corrupt_journal_block/image.gz, we see these journal contents:
debugfs: logdump -c
Journal starts at block 1, transaction 3

Found expected sequence 6, type 1 (descriptor block) at block 10
Found expected sequence 6, type 2 (commit block) at block 12
No magic number at block 13: end of journal.
This test checks the "continues replaying even after a corrupt journal block"
feature by using the journal to overwrite the blocks of a file. Originally, /a
contains 3 blocks worth of 'a':

Inode checksum: 0x98f0c609
EXTENTS:
(0-2):1090-1092
(For the ease of the reader, 1090 == 0x442.)
In the first transaction, we overwrite the first two blocks of /a with 'b'.
debugfs: bmap <8> 1
33
debugfs: bd 33
0000 c03b 3998 0000 0001 0000 0003 0000 0442 .;9............B

0060 0000 000a 0000 0000 cdc6 611c 0000 0000 ..........a.....
Note the two descriptor tags referring to blocks 1090-1091.
debugfs: bmap <8> 2
35
debugfs: bd 35
0000 6262 6262 6262 6262 6262 6262 6262 6262 bbbbbbbbbbbbbbbb

debugfs: bd 36
0000 6262 6262 6262 6262 6262 6262 6262 6262 bbbbbbbbbbbbbbbb
*
We commit the first transaction in block 4.
In the second transaction, we revoke the first block of the first transaction.
At this point, /a will be left with a block of 'a', a block of 'b', and another
block of 'a':
debugfs: bmap <8> 5
38
debugfs: bd 38
0000 c03b 3998 0000 0005 0000 0004 0000 0018 .;9.............
0020 0000 0000 0000 0442 0000 0000 0000 0000 .......B........
This was done mostly to test ... NUTS, a bug. When we see an error, we ought
to kill all the revoke records and restart the replay, because the revoke table
could've nixed a previous journal block.
Ok, I'll go fix that.
In the third transaction, we overwrite the first block of /a (1090) with 'c'.
However, I have corrupted the journal block (by overwriting some of it with
'-') so that this block should not replay:
debugfs: bmap <8> 7
40
debugfs: bd 40
0000 c03b 3998 0000 0001 0000 0005 0000 0442 .;9............B
0020 0000 0008 0000 0000 9881 d4c5 0000 0000 ................
debugfs: bmap <8> 8

debugfs: bd 41
0000 2d2d 2d2d 2d2d 2d2d 2d2d 2d2d 2d2d 2d2d ----------------
0020 6363 6363 6363 6363 6363 6363 6363 6363 cccccccccccccccc
*
In the fourth transaction, we overwrite the last block of /a (1092) with 'd':
debugfs: bmap <8> 10
43
debugfs: bd 43
0000 c03b 3998 0000 0001 0000 0006 0000 0444 .;9............D
0020 0000 0008 0000 0000 61ac 3738 0000 0000 ........a.78....
debugfs: bmap <8> 11

debugfs: bd 44
0000 6464 6464 6464 6464 6464 6464 6464 6464 dddddddddddddddd
*
As you can see from the expect output, after replaying the journal, the file
contents are a block of 'a', then a block of 'b', and then a block of 'd',
which is consistent with skipping the corrupted block but replaying the rest.
This is actually broken; the file contents SHOULD be two blocks of 'b' and a
block of 'd'.

If a libext2fs client has provided a get_alloc_block hook, we need to
ensure that all code paths in the library use it to allocate blocks.

I noticed you didn't replace ext2fs_new_block[2] with
ext2fs_alloc_block[2] everywhere, because ext2fs_alloc_block[2]() does
extra work; specifically, it zeroes the newly allocated data block.
In the case of mkjournal.c, that would be disastrous from a
performance perspective, since we go to significant work to avoid
zeroing blocks one at a time.
But in other cases, when we create a symlink, expand a directory,
etc., we're still doing a double write (once in ext2fs_alloc_block,
and then a second time after ext2fs_alloc_block returns).
Hmm... I wonder if we can get away with changing ext2fs_new_block2(fs,
goal, bmap, ret_blk) so that if bmap is NULL, we change its behavior
so that (a) it tries to use the get_alloc_block() hook if it is present, and
(b) it will try to load the block bitmap if it is not already loaded,
instead of returning an error.
There are very few clients that are registering a get_alloc_block hook
today, and so it seems highly unlikely that this will cause problems.
What do you think?

Quite probably. I tried to avoid API behavioral change, at least for the
inital patch, though I was thinking that a general cleanup was probably in
order.

e2fuzz found the usual "using the wrong bitmap" bug in mkjournal.c, and patch
#29 (which you just applied) makes e2fsck a client of expand_dir. So long as
e2fsck is never changed to use _mkdir() and _symlink() we can probably get away
with not bothering, but then we'll quietly introduce this corruption bug again
if e2fsck ever does start using them.
Also any other client who uses the alloc_block hook will be silently broken.
Less broken than now, but I don't like discarding a small fix because we don't
guess anyone will care if it stays broken.

It turns out that making a behavioral change could very well break
some callers --- including e2fsck (see e2fsck_get_alloc_block for an
example of wahy). What I'm currently thinking about is an API sort of
like this:
errcode_t ext2fs_alloc_blocks(ext2_filsys fs, blk64_t goal,
unsigned int *num_blocks,
char *block_buf, int flags, blk64_t *ret)
... which can be used to efficiently allocate up to *num_blocks blocks
at a time, much like the mballoc interface. I suspect that would be
useful for a number of different cases, including ext2fs_fallocate and
mk_hugefiles.c.
What I'm currently wondering about is whether it's worth the interface
complexity to have something like a "struct ext2fs_allocation_request"
structure, so we can potentially add more hints that a future
implementation might use, or whether that's not worth it.
What do folks think?

I currently patched that the stupid way -- by temporarily swapping
fs->get_alloc_block with NULL in new_block2() while we call the function
pointer.
(Also by fixing e2fsck.)

I'm not sure changing a struct vs. changing whatever parameters we feed into
that function is all that much different. I guess you could get around
structure size changes by forcing callers to use a library allocator function.
But OTOH large allocations are probably rare.

Yes, but I'm thinking of something which is a superset of
ext2fs_alloc_block2(). That is, that it should call the
get_alloc_block hook (and also adding a possible get_alloc_blocks
hook), and that a flag would control whether the data blocks would be
zero'ed or not. (Indeed, I was thinking originally of calling it
ext2fs_alloc_block3.)

We can also insulate against structure sizes by using padding fields,
but the ultimate question is how complicated we want to make this
interface. We know it will be used by mk_hugeblock and the fallocate
interface. In theory it could be use by your fuse driver to do
allocations more efficiently. There is the question of whether it's
worth it, although it has crossed my mind that this might be an
interesting place to start experimenting with an eventual replacement
of the buddy-bitmap implementation in mballoc with something that use
in-memory rbtrees, for example....

Ah, I see. I _think_ the big difference between what you're talking about and
my new_range implementation is that new_range finds you a chunk of free blocks
that could be longer than what you asked for and lets you decide what to do
with them (like new_block does) whereas alloc_blocks3 (or alloc_range) would
find that chunk and call alloc_stats on just the piece you want.
I'd prefer the new_range feature since you can do some trivial preallocation
with it, but I'm open to an alloc_block3 too.
(I dislike the name alloc_block3, since we're really allocating a range.)
Anyway, we'll see what everyone thinks when the patch comes out in part 6.

Enhance disable_uninit_bg() to return error codes -- if something goes
wrong, we want to flag the FS as needing a fsck and exit. Mr. Reardon
discovered that tune2fs -O ^metadata_csum on a FS with a corrupt
bitmap would leave the FS in a weird state.

If the badblocks list says that the badblocks inode is bad, it's quite
likely that badblocks is broken. Worse yet, if the root inode is in
the same block as the badblocks inode (likely since they're adjacent),
the filesystem becomes unfixable because pass3 notices the bad root
inode and exits.
So... if we encounter this case, just kill the badblocks inode.

If there isn't space in the root directory to add the lost+found
entry, try expanding the root directory before failing the fsck.

When reading extended attributes, check e_value_offs to make sure that
it starts in the value area and not the name area. The attached test
case image will crash the kernel if it is mounted and you append more
than 4096 bytes of data to /a, due to insufficient validation.

Darrick, can you take a look and see if everything landed as you
expect?
23-25 is a new feature (pending comments on 23, and I remember wanting
to take a much closer look at 24 and 25 from a month or two ago), and
26 is pending some comments I had vis-a-vis ext2fs_new_block() vs
ext2fs_get_block(), so if you want to send out patchbomb part 6 with
what's left of part 5, that might be appropriate.
Thanks for all of your work on e2fsprogs!

Hmm, works for me. Could you make sure you've done a "make clean" and
also a "git clean"? In particular, make sure you don't have a
leftover file in debugfs/jfs_user.h....

There aren't any stray jfs_user.h files, but rearranging DEBUGFS_CFLAGS seems
to fix it. On Ubuntu 14.04 it seems that the compile command for
lib/ext2fs/journal.o is:
gcc -I. -I../../lib -I../../lib -Wall -g -O2 -fstack-protector --param=ssp-buffer-size=4 -DHAVE_CONFIG_H -I./../../e2fsck -DDEBUGFS -c ../../debugfs/journal.c -o journal.o
...which means that it picks up lib/ext2fs/jfs_user.h instead of the one in
e2fsck/. The attached patch changes it to:
gcc -I./../../e2fsck -I. -I../../lib -I../../lib -Wall -g -O2 -fstack-protector --param=ssp-buffer-size=4 -DHAVE_CONFIG_H -DDEBUGFS -c ../../debugfs/journal.c -o journal.o
...which runs the compile ok.

Ah, now I see why it works for me. I was using a VPATH build
directory, so it wasn't finding the one in lib/ext2fs/jfs_user.h. But
you're probably building in the source directory, so it was finding it
via "-I.".
Your patch looks good, thanks. I'll apply it and push out an update.

Cool, thanks! Yes, I do build out of the source dir.
Part 6 will have: e2fsck readahead; alloc_block cleanup; dumpe2fs output
cleanup; reporting of foreign FSes being fed to tune2fs/debugfs/e2fsck; uninit
block handling for fileio; 32->64bit resize2fs; fallocate; fuse2fs.
I'll give it all a spin on the usual x64/ppc64/arm64/i386 testbeds. Hopefully
it'll be out tomorrow.
