If sysconf(_SC_NPROCESSORS_CONF) returns zero, this can cause a divide

if _SC_NPROCESSORS_CONF returns an invalid value.

The in-memory data structures used time_t for the grace period (which
is a delta timestamp denominated in seconds), as well as the soft
limit expiration time (which is an actual time_t). Use an explicit
__u32 for the former, and the __u64 for the latter.
This silences a Coverity warning, but more importantly, using an
explicit __u64 for the expiration time means that running e2fsck on a
platform with a 32-bit time_t, and it needs to read and then modify a
quota structure, we won't lose the high 32-bits of the quota
expiration time.

When moving the inode table, if writing the (partially overlapping)

before bailing out. If that write unding the initial write fails,

Debian has a package called "systemctl" which provides a systemctl

The problem with explicitly setting _FILE_OFFSET_BITS is that
it's not necessarily a no-op on a 64-bit platform with a 64-bit off_t.
Apparently glibc's mips64el which end up using a different structure
definition for struct stat, and this causes a compatibility problem
with libarchive. It's not needed on mips64el, since off_t is 64-bits,
but it actually causes problems.
So remove it, since we now use the autoconf's AC_SYS_LARGEFILE, which
will set _FILE_OFFSET_BITS when it is necessary (such as on a 32-bit
i386 Linux platform), and will skip it when it is unnecessary.

Teach configure the --without-libarchive option, which forcibly
disables use of the libarchive library.
The option --with-libarchive=direct will disable the use of dlopen,
and will link mke2fs with -larchive directly. This doesn't work when
building mke2f.static, since -larchive has a large number of
depedencies, and even "pkgconf --libs --static libarchive" doesn't
provide all of the appropriate library dependencies. :-(

Manually count the number free clusters in the last block group since
it might not be a multiple of 8, and using ext2fs_bitcount() might not
work if bitmap isn't properly padding out.
In addition, when setting up the block bitmap for the resized file
system, resize2fs was setting up the "real end" of the bitmap in units
of blocks instead of clusters.

We explicitly decided not to reserve space for a 64-bit dtime, since
it's never displayed or exposed to userspace. The dtime field is used
a linked list for the ophan list, and for forensic purposes when
trying to determine when an inode was deleted. So right after the
2038 epoch, a deleted inode might end up with a dtime which is zero or
smaller than the number of inodes, which will result in e2fsck
reporting a potential problems. So when we set the dtime, make sure
that the dtime won't be mistaken for an inode number.

This issue was flagged by Coverity, although its analysis was
incorrect. This isn't actually a memory overrun / security issue, but
rather a functional correctness issue since POSIX allows reads and
writes to be partially completed, and in those cases qcow2_copy_data()
could result in a corrutped qcow2 file.

How timestamps are encoded in inodes and superblocks are different.
Unfortunately, commit ca8bc9240a00 which added post-2038 timestamps
was (a) overwriting adjacent superblock fields and/or attempting
unaligned writes to a 8-bit field from a 32-bit pointer, and (b) using
the incorrect encoding for timestamps stored in inodes. Fix both of
these issues, which were found thanks to UBSAN.

If archive.h is available during compilation, enable mke2fs to read a
tarball as input. Since libarchive.so.13 is opened with dlopen,
libarchive is not a hard library dependency of the resulting binary.
In comparison with feeding a directory tree to mke2fs via -d this has
the following advantages:
- no superuser privileges, nor fakeroot, nor unshared user namespaces
are needed to create filesystems with arbitrary ownership information
and special files like device nodes which otherwise require being root
- by reading a tarball from standard input, no temporary files need to
be written out first as mke2fs can be used as part of a shell pipeline
which reduces disk usage and makes the conversion independent of the
underlying file system
A round-trip from tarball to ext4 to tarball yields bit-by-bit identical
results

Commit f7ef5f3e356d ("e2fsck: check all sparse_super backups") tries
to limit the number of block groups to search for backup superblocks
based on ctx->num_blocks. Unfortunately, get_backup_sb() gets called
before ctx->num_blocks is set, so we try all block groups up to 2**32
- 1. Not only does this waste time trying to read from blocks that
don't exist, it triggers the UBSAN checker when multiplying a very
large number by the block size.
Fix this by using ext2fs_get_Device_size(), and if that isn't
available, arbitrarily cap things so that we search block groups up to
128.

The calloc prototype is:

So, just swap the number of members and size arguments to match the prototype, as
we're initialising 1 struct of size `sizeof(...)`. GCC then sees we're not

resize2fs block_mover() flushes data after each extent and, curiously,
only if progress indicator is enabled, every inode_blocks_per_group
blocks.
This significantly affects performance, e.g. on a tested large
filesystem on top of MD-RAID6+LVM+dm-crypt these flush calls reduce the
operation rate from approx. 500MB/s to 5MB/s, causing extremely long
shrinking times for large size deltas (70TB in my case).
Since this step performs just plain data copying and does not e.g. save
any progress/checkpoint information or similar metadata, it seems like
this flushing is of very limited usefulness, especially when considering
the (in some cases) 100x performance impact.
Remove the mid-operation flushes and only flush after all blocks have
been moved.

If a bad inode is found it will be deallocated. However, if the filesystem has
quota enabled, the quota information isn't being updated accordingly. This
issue was detected by running fstest ext4/019.
This patch fixes the issue by decreasing the inode count from the
quota and, if blocks are also being released, also subtract them as well.
While there, and as suggested by Andreas Dilger, the deallocate_inode()
function documentation is also updated by this patch to make it clear what
that function really does.

If that happens and quota is enabled in the filesystem, the quota information

This patch simply updates the quota data accordingly, after the directory is

According to the mke2fs man page, the supported cluster-size values
for an ext4 filesystem are 2048 to 256M bytes. However, this is not
the case.
When mkfs is run to create a filesystem with following specifications:
* 1k blocksize and cluster-size greater than 32M
* 2k blocksize and cluster-size greater than 64M
* 4k blocksize and cluster-size greater than 128M
mkfs fails with "Invalid argument passed to ext2 library while trying
to create journal" error. In general, when the cluster-size to blocksize
ratio is greater than 32k, mkfs fails with this error.
Went through the code and found out that the function
`ext2fs_new_range()` is the source of this error. This is because when
the cluster-size to blocksize ratio exceeds 32k, the length argument
to the function `ext2fs_new_range()` results in 0. Hence, the error.
This patch corrects the valid cluster-size values.

This patch prepares the expansion of GDT blocks beyond a
single group, by make mke2fs to not set BLOCK_UNINIT on
groups with GDT blocks, block/inode bitmaps, or inode table
blocks allocated.
Otherwise, we still rely on kernel side to initialize the
block bitmap if the groups has BLOCK_UNINIT set, and the
kernel doesn't know a group could have GDT blocks allocated,
so it would make an bad block bitmap.
As a result, expect output of several tests needs to be changed,
especially if the test uses dumpe2fs to print the group summary.

This patch is part of the preparation required to allow
GDT blocks expand beyond a single group,
it introduces 2 new interfaces:
- ext2fs_count_used_blocks(), to return the blocks used
in the bitmap range.
- ext2fs_reserve_super_and_bgd2() to return blocks used by
superblock/GDT blocks for every group, by looking up blocks used.

Teach e2fsck to look for backup super blocks in the "sparse_super"
groups, by checking group #1 first and then powers of 3^n, 5^n,
and 7^n, up to the limit of available block groups.
Export ext2fs_list_backups() function to efficiently iterate groups
for backup sb/GDT instead of checking every group. Ensure that the
group counters do not try to overflow the 2^32-1 group limit, and
try to limit scanning to the size of the block device (if available).

For flex_bg enabled fs, we could merge the

this improves mke2fs time on large devices
when lazy_itable_init is disabled.
On a 977TB device, unpatched mke2fs was running
for 449m10s before getting terminated manually.
strace shows huge number of fallocate, given the
offset from fallocate it has done 41% of the inode

Commit 42c11edd0863 ("ext2fs_open[2](), return an error if s_desc_size
is too large") added a check for an insanely large s_desc_size to
prevent some failures triggered by fuzz testing. However, it would
allow e2fsck to fall back to recover the file system by using the
backup superblocks by having e2fsck pass the flag
EXT2_FLAG_IGNORE_SB_ERRORS. But by allowing an s_desc_Size of zero,
it's possible that e2fsck will die with a division of zero error.
With this fix, e2fsck will now print an error message and exit
instead.

overflow in 2038, but similar handling is not in e2fsprogs.

ext2fs_super_tstamp_get() and ext2fs_super_tstamp_set().
Add helper macro for inode _extra timestamp fields
ext2fs_inode_xtime_get() and ext2fs_inode_xtime_set().
Add helper macro ext2fs_actual_inode_size() to avoid open
coding the i_extra_isize check in multiple places.
Remove inode_time_to_string() since this is unused once callers
change to time_to_string(ext2fs_inode_xtime_get()) directly.
Fix inode_includes() macro to properly wrap "inode" parameter,
and rename to ext2fs_inode_includes() to avoid potential name
clashes. Use this to check inode field inclusion in debugfs
instead of bare constants for inode field offsets.

Brian J. Murrell reported that e2scrub reports failures with one of his
filesystems. From the email discussion after he supplied a metadump:
AHA! This is an ext2 filesystem, since it doesn't have the
"has_journal" or "extents" features turned on:
# e2image -r /tmp/disk.qcow2 /dev/sda
# dumpe2fs /dev/sda -h
dumpe2fs 1.47.1~WIP-2023-12-27 (27-Dec-2023)
Filesystem volume name: <none>
Last mounted on: /opt
Filesystem UUID: 2c70368a-0d54-4805-8620-fda19466d819
Filesystem magic number: 0xEF53
Filesystem revision #: 1 (dynamic)
Filesystem features: ext_attr resize_inode dir_index filetype sparse_super large_file
Filesystem flags: signed_directory_hash
Default mount options: user_xattr acl
Filesystem state: not clean with errors
(Note: Filesystem state == "clean" means that EXT2_VALID_FS is set in
the superblock s_state field; "not clean with errors" means that the
flag is not set.)
I bet the "journal only" preen doesn't actually reset the filesystem
state either:
# e2fsck -E journal_only -p /dev/sda
# dumpe2fs /dev/sda -h | grep state
dumpe2fs 1.47.1~WIP-2023-12-27 (27-Dec-2023)
Filesystem state: not clean with errors
Nope.
So now I know what happened -- when mounting an ext* filesystem that
doesn't have a journal, the driver clears EXT2_VALID_FS from the primary
superblock. This forces the system to run e2fsck after a crash, because
that's what you have to do for unjournalled filesystems.
The "e2fsck -E journal_only -p" call in e2scrub only replays the
journal. Since there is no journal, it exits almost immediately.
That's the intended behavior, but then it means that the "e2fsck -fy"
call immediately after sees that the superblock doesn't have
EXT2_VALID_FS set, sets it, and makes e2fsck return 1.
So that's why you're getting the e2scrub failures.
Contrast this to what you get when the filesystem has a journal:
# dumpe2fs -h /dev/sdb
dumpe2fs 1.47.0 (5-Feb-2023)
Filesystem volume name: <none>
Last mounted on: <not available>
Filesystem UUID: e18b8b57-a75e-4316-87ce-6a08969476c3
Filesystem magic number: 0xEF53
Filesystem revision #: 1 (dynamic)
Filesystem features: has_journal ext_attr resize_inode dir_index filetype needs_recovery sparse_super large_file
Filesystem flags: signed_directory_hash
Default mount options: user_xattr acl
Filesystem state: clean
Filesystems with journals retain their EXT4_VALID_FS state when they're
mounted.
Hmm. What e2scrub should do about unjournalled filesystems is a thorny
question. My initial thought is that it should skip them, because a
mounted unjournalled filesystem cannot by definition be kept consistent.
Therefore, teach e2scrub_all to avoid them and e2scrub to fail them at
the onset.
Restricting the scope of e2scrub sucks, but in the meantime at least it
means that your filesystem isn't massively corrupt. Thanks for the
metadump, it was very useful for root cause analysis.

Per FHS 3.0, non-PATH executable binaries are supposed to live under

move it to libexec in case some distro some day tries to mount /usr/lib
as noexec or something. Also, there's no reason why these scripts need
to be put under an arch-dependent path.

For changing inode size (-I) and setting quota fearture (-Q), tune2fs
only check whether the filesystem is umounted. Considering mount
namepspaces, the filesystem is umounted, however it already be left
in other mount namespace.
So we add one check whether the filesystem is not in use with using
EXT2_MF_BUSY flag, which can indicate the device is already opened
with O_EXCL, as suggested by Ted.

The unending stream of syzbot bug reports and overwrought filing of CVEs
for corner case handling (i.e. things that distract from actual user
complaints) in ext4 has generated all sorts of of overheated rhetoric
about how every bug is a Serious Security Issue(tm) because anyone can
craft a malicious filesystem on a USB stick, insert the stick into a
victim machine, and mount will trigger a bug in the kernel driver that
leads to some compromise or DoS or something.
I thought that nobody would be foolish enough to automount an ext4
filesystem. What a fool I was! It turns out that udisks can be told
that it's okay to automount things, and then GNOME will do exactly that.
Including mounting mangled ext4 filesystems!
<delete angry rant about poor decisionmaking and armchair fs developers
blasting us on X while not actually doing any of the work>
Turn off /this/ idiocy by adding a udev rule to tell udisks not to
automount ext4 filesystems.
This will not stop a logged in user from unwittingly inserting a
malicious storage device and pressing [mount] and getting breached.
This is not a substitute for a thorough audit of all codebases. This is
not a substitute for lklfuse. This does not solve the general problem
of in-kernel fs drivers being a huge attack surface. I just want a
vacation from the sh*tstorm of bad ideas and threat models that I never
agreed to support.

systemd services provide an "instance name" that can be associated with
a particular invocation of a service. This allows service users to
invoke multiple copies of a service, each with a unique string. For
e2scrub, we pass the mountpoint of the filesystem as the instance name.
However, systemd services aren't supposed to have slashes in them, so
we're supposed to escape them.
The canonical escaping scheme for pathnames is defined by the
systemd-escape --path command. Unfortunately, we've been adding our own
opinionated sauce for years, to work around the fact that --path didn't
quite work right in systemd before January 2017. The special sauce is
incorrect, and we no longer care about systemd of 7 years past.
Clean up this mess by following the systemd escaping scheme throughout
the service units. Now we can use the '%f' specifier in them, which
makes things a lot less complicated.

When repairing a file system with s_errno missing from the journal
superblock but the file system superblock contains the ERROR_FS flag,
the ERROR_FS flag on the file system image is overwritten after the
journal replay, followed by a reload of the file system data from disk
and the ERROR_FS flag in memory is overwritten. Also s_errno is not set
and the ERROR_FS flag is not reset. Therefore, when checked later, no
forced check is performed, which makes it possible to have some errors
hidden in the disk image, which may make it read-only when using the
file system. So we save the ERROR_FS flag to the superblock after the
journal replay, instead of just relying on the jsb->s_errno to do this.

dumpe2fs has never been modified to correctly report block ranges
corresponding to free clusters in block allocation bitmaps from bigalloc
file systems. Rather than reporting block ranges covering all the
blocks in free clusters found in a block bitmap, it either reports just
the first block number in a cluster for a single free cluster, or a
range beginning with the first block number in the first cluster in a
series of free clusters, and ending with the first block number in the
last cluster in that series.
This behavior causes xfstest shared/298 to fail when run on a bigalloc
file system with a 1k block size. The test uses dumpe2fs to collect
a list of the blocks freed when files are deleted from a file system.
When the test deletes a file containing blocks located after the first
block in the last cluster in a series of clusters, dumpe2fs does not
report those blocks as free per the test's expectations.
Modify dumpe2fs to report full block ranges for free clusters. At the
same time, fix a small bug causing unnecessary !in_use() retests while
iterating over a block bitmap.

Add a test for the commit "e2fsck: fix handling of a invalid symlink
in an inline_data directory"
Signed-off-by: Theodore Ts'o <tytso@mit.edu>
|
|
If there is an inline directory that contains a directory entry to an
invalid symlink, and that invalid symlink is the portion of the inline
directory stored in an xattr portion of the inode, this can result in
a buffer overrun.
When check_dir_block() is handling the in-xattr portion of the inline
directory, it sets the buf pointer to the beginning of that part of
the inline directory. This results in the scratch buffer passed to
e2fsck_process_bad_inode() to incorrect, resulting in a buffer overrun
if e2fsck_pass1_check_symlink() needs to read the symlink target (when
the symlink is too long to fit in the i_blocks[] space).
This commit fixes this by using the original cd->buf instead of buf,
since it can get modified when handling inline directories.

clean" is intended to request permission before removing the r/o
compat feature, orphan_present. However, it is normal if the orphan
file is empty, and removing the r/o compat feature is a good thing so
that the file system can be mounted on older kernels.
When a file system with an orphan_file feature is mounted, the
orphan_present feature is set, and it is cleared when the file system
is cleanly unmounted. IF the sytstem crashes when there are no inodes
in the orphan file, e2fsck should just silently clear the flag in
preen mode.

SetFilePointer requires the upper 32 bit of the position to be passed
separately, which the code did not do, causing the position to be
interpreted as a 32-bit value. Use SetFilePointerEx instead and pass the
entire 64-bit value.

We attempt to fix directories which have a bad/corrupted htree index
node by completely rebuilding the directory htree nodes. Since this
is a very safe thing to do and has no risk of losing directory
entries, we've enabled this for preen mode. Unfortunately, subsequent
index nodes look like empty directory entries that fill the entire
block --- without a checksum at the end of the directory. So these
nodes will be treated as a completely corrupted directory block, and
this will *not* be fixed while in preen mode.
So add code to treat an empty directory entry which covers the entire
block as valid if the directory is already on the list of inodes to be
rebuilt.

test_rw() and test_nd() need to allocate two or three times the product
of the block size and the block counts. This can overflow the signed int
type of block_size and result in allocate_buffer() being called with a
value smaller than intended. Once that buffer is written to, badblocks
segfaults.
Since allocate_buffer() accepts a size_t, change the input validation to
use SIZE_MAX and cast accordingly when calculating the argument.
Fixing the segfault allows larger values to be passed to read() and
write(); these need to be cast to size_t as well in order to avoid a
signed integer overflow causing failure, in which case badblocks would
fall back to testing a single block at once.

Since the conditional checks the product of block_size and
blocks_at_once, reporting that the problem is solely with

We can't call the error handler while holding the CACHE_MUTEX (see
previous commit, "libext2fs: unix_io: fix_potential error path
deadlock in reuse_cache()" for details), so first try to write out all
of the dirty blocks in the cache, and then for those where we had
errors, then call the error handler.
Signed-off-by: Theodore Ts'o <tytso@mit.edu>

This was reported by [1] but the fix was incorrect. The issue is that
when unix_io was made thread-safe, it was necessary that to add a
CACHE_MUTEX to protect multiple threads from potentially colliding
with the very simple writeback cache used by the unix_io I/O manager.
The original I/O manager was purposefully kept simple, used a
fixed-size cache; accordingly, the locking used also kept simple, and
used a single global mutex.
[1] https://lore.kernel.org/r/310fb77f-dfed-1196-c4ee-30d5138ee5a2@huawei.com
The problem was that if an application (such as e2fsck) registers a
write error handler, that handler would be called with the CACHE_MUTEX
still held, and if that application tried to do any I/O --- for
example, closing the file system using ext2fs_close() and then exiting
--- the application would deadlock.
We should perhaps fix this either by deciding that the simple Unix I/O
cache doesn't actually buy much beyond some system call overhead, or
by putting in a full-fledged buffer I/O cache system which uses a much
larger cache with allocated memory, fine-grained locking and Direct
I/O to prevent double cache at the kernel and userspace level.
However, for now, fix the problem by waiting until after we have
released the CACHE_MUTEX before calling the write handler. This is
good enough given how e2fsck's ehandler.c use case, and in practice no
one else really uses the error handler in any case.

Since commit 4e5f24ae4267 ("Use an autoconf test to detect for a BSD- or
GNU-style qsort_r function"), e2fsck fails to build for Android because
lib/support/sort_r.h assumes that qsort_r() is always available on
"Linux", but in fact it's not supported by Android's libc.
Rename _SORT_R_LINUX to _SORT_R_GNU to clarify that it's really the
glibc convention for qsort_r(), not the "Linux" convention per se, and
make sort_r.h stop setting it automatically when __linux__ is defined.
Note: this change does *not* prevent glibc's qsort_r() from being used
when e2fsprogs is built using the autotools-based build system, as
'configure' checks for qsort_r() too. This change just affects the
fallback behavior for when qsort_r() was not already detected.

The upstream build system for e2fsprogs doesn't use
-fno-strict-aliasing, so update the Android.bp files to match.
Note: Android's build system currently uses -fno-strict-aliasing by
default anyway, so this change doesn't actually enable strict aliasing.
But that's a bit besides the point. The point is that this project

Some .c files in lib/uuid/ contain the following:

#define UUID MYUUID

This seems to have been intended to allow the use of a local "UUID" type
without colliding with "UUID" in the Windows API. However, this is
unnecessary because there's no local "UUID" type -- there's only uuid_t.
None of these .c files need the include of windows.h, either.
Finally, the unconditional definition of _WIN32_WINNT causes a compiler
warning when the user defines _WIN32_WINNT themself.
Since this code is unnecessary and is causing problems, just remove it.
