Put ELF_OTHER_LIBS in the right place for the linker
Commit
a7c17431b9 attempted to fix a problem where the system
libraries might get used instead of local libraries for things like
-lcom_err. It tried to accomplish this by moving $(ELF_OTHER_LIBS) to
before $(LDFLAGS).
Unfortunately, this was the wrong fix; $(ELF_OTHER_LIBS) *MUST* be
after the object files, or the linker might not pull in the necessary
library and not include it into the DT_NEEDED section of the shared
library. The proper fix is to add a -L$(LIB) before $(LDFLAGS), and
then remove the -L option from all of the ELF_OTHER_LIBS definitions
in the library Makefiles.

This is useful for large cloud installations where there are a large

The report_time and report_verbose options, which are the same as the

libext2fs: fix uninit block calculation when inodes_per_block < first_ino
The following commands:

mke2fs -N 256 -t ext4 /tmp/foo

for this is that the explicit request for 256 inodes causes the number

assumed that all of the reserved inodes would be in the first block

It could also make final executable link to fail when shared libraries

This reverts commit
47c1b8e16668daa6e74cee3c7b8bdf237ffefe70.
The original reason for this commit was to speed up boots for hard
drives. However, I've measured the time difference on a 1TB laptop
drive, and it's not significant: 70ms vs 10ms when running e2fsck on a
clean file system.
The problem with this optimization is that we don't notice if the
journal superblock has a non-zero s_errno field. If we don't transfer
the error indicator from the journal superblock to the file system
superblock, then the kernel will transfer it when the file system is
remounted read-write, causing scary messages to appear in the syslog.
(And since there was a bug in the kernel code which didn't clear the
error indicator in the journal superblock, it would never get
cleared.)

logsave: fix fd leak which could cause logsave to hang
The logsave program is leaking a file descriptor when it forks and
execs the program which forks a process which hangs around. In the
case of /etc/init.d/checkroot, this would be fsck. This file
descriptor never gets closed, so it's still present when fsck runs
e2fsck, and then if e2fsck has its own logging enabled using (in
/etc/e2fsck.conf):
[options]
log_dir = /mnt
log_filename = e2fsck-%N.%h.INFO.%D-%T
log_dir_wait = true
then e2fsck will fork off a process waiting for /mnt to get remounted
read/write. This causes logsave to never get an EOF from its pipe, so
it hangs waiting for the read to fail --- which won't happen due to
the file descriptor leak which is still being held open by e2fsck's
forked child process. And so /etc/init.d/checkroot hangs, and the
root file system never gets remounted read/write, and we deadlock.
Fix the problem by closing the pipe fd so the logsave program doesn't
end up leaking it to its descendent processes.

tune2fs/quota: always create hidden quota files
Currently 'tune2fs -O quota <dev>' will try to use existing
quota files and write their inode numbers in the superblock.
Next e2fsck run then converts these into hidden quota inodes
(ino #3 & #4). But this approach has problems:
1) Before e2fsck run, the inodes are visible to the user and
might get corrupted or removed or replaced by the user.
2) Since these are user visible, we have to include
their block usage in the quota accounting. But once
these inodes are hidden, e2fsck will have to decrement
their usage from the quota accounting (which e2fsck
currently doesn't do and instead reports error).
(the following used to give e2fsck error previously:
# assume <dev> has aquota.user & aquota.group files
$ tune2fs -O quota <dev> # stores ino# of quota files in
# ext4 superblock
$ e2fsck -f <dev> # hides quota files, but now quota
# usage is incorrect.

hidden quota inodes at 'tune2fs -O quota' time iteself. The
usage is computed freshly and limits are copied from the

Unfortunately, this simulation is not perfect; in particular it does

uninitialized blocks allocated using fallocate with
FALLOC_FL_KEEP_SIZE, and it leads to e2fsck incorrectly complaining

e2fsck: correctly propagate error from journal to superblock
If the file system is mounted read-only after a file system error has
been detected, the fact that an error occurred is written to the
journal. This is important because while the journal is getting
replayed, the error indication in the superblock may very well get
overwritten.
Unfortunately, the code to propagate the error indication from the
journal to superblock was broken because this was being done before
the old file system handle is thrown away and the file system is
re-opened to ensure that no stale data is in the file system handle.
As a result, the error indication in the superblock was never written
out.
To fix this, we need to move the check if the journal's error
indicator has been set after the file system has been freed and
re-open.

e2fsck: handle an already recovered journal with a non-zero s_error field
If a file system was remounted read-only after a file system
corruption is detected, and then that file system is mounted and
unmounted by the kernel, the journal would have been recovered, but
the kernel currently leaves the s_errno field still set. This is
arguably a bug, since it has already propgated the non-zero s_errno
field to the file system superblock, where it will be retained until
e2fsck has been run.
However, e2fsck should handle this case for existing kernel by
checking the journal superblock's s_errno field even if journal
recovery is not required.
Without this commit, e2fsck would not notice anything wrong with the
file system, but a subsequent mount of the file system by the kernel
would mark the file system's superblock as needing checking (since the
journal's s_errno field would still be set), resulting an full e2fsck
run at the next reboot, which would find nothing wrong --- and then
when the file system was mounted, the whole cycle would repeat again.
I had seen reports of this in the past, but it wasn't until recently
that I realized exactly how this had come about, since normally e2fsck
would be run automatically before the file system is mounted again,
thus avoiding this problem. However, a user using a rescue CD who
didn't run e2fsck before mounting the a file system in this condition
could trigger this situation, and unfortunately, with previous
versions of e2fsprogs and the kernel, there would be no way out no
matter what the user tried to do.

tests: use make rules to run tests in parallel
Change the e2fsck/mke2fs/tune2fs/e2image/debugfs regression tests to
be driven by Makefile rules instead of by a script loop. This allows
the tests to be run in parallel like a build and reduces testing time
significantly.
One major change to the tests themselves is to printing the test name,
description, and status together after the test has passed or failed,
to avoid mixing lines from the tests. The other major change is to
use unique temporary filenames for each test, which was mostly handled
already via
b4db1e4c7461a50e18c9fd135b9f1ba6f27e4390, but in some
cases temporary files are changed to use $test_name.tmp to avoid any
collision between running tests.
On my old 2-CPU system it reduced the testing time from 160s to 40s.
Much of the savings is from the MMP test delays running in parallel.
It still takes the time of the slowest test, f_mmp_garbage, though
there will be ongoing benefit in the future as more tests are added
since the wallclock time will not increase linearly for each test.
Tests were run with various combinations of "make -j", and "make -j2"

c859cb1de0d624caa0779fb17d1a53766143136e in ext2fs.h caused

Since ext2fs_open_file() and ext2fs_stat() are not performance

and the needed function headers can be handled properly in one file.

e2fsck: fix checks done for mounted vs. read-only
Currently, if e2fsck is run without the "-n" flag (i.e. it
might modify the filesystem), there is no guarantee that it will
open the filesystem with the EXCLUSIVE flag (i.e. O_EXCL) to
prevent the block device from being checked (in most cases this
means mounted, but it could also be an MD/LVM member device).
Conversely, if e2fsck is run with "-n" (i.e. read-only), and
/etc/mtab or /proc/mounts does not report the block device as
mounted then e2fsck thinks the filesystem is unmounted. In this
case, e2fsck incorrectly sets the EXCLUSIVE flag, which causes
the check to fail, even though e2fsck is running read-only.
To fix this, do not open with EXCLUSIVE if it is a read-only check,
and always open with EXCLUSIVE if the filesystem might be changed.
This also prevents filesystem mounts while e2fsck is running.
Also refuse allow e2fsck to run at all if the filesystem is BUSY.
The e2fsck check_mount() was checking for MOUNTED, but not BUSY,
and it should refuse to run outright if the block device is BUSY.
The previous MOUNTED heuristics pre-date the O_EXCL reservation
by the kernel, so there could be uncertainty due to stale /etc/mtab
data, but with newer kernels a busy device should never be modified.

so I've added support for a good-enough emulation of memalign()'s

valloc() is returning a pointer which is sufficiently aligned given
the requested alignment. This won't work if you try to operate on a

I've also added a unit test for ext2fs_get_memalign() so we can be
sure it's working as expected. I've tested the code paths with
HAVE_POSIX_MEMALIGN defined, HAVE_POSIX_MEMALIGN undefined, and
HAVE_POSIX_MEMALIGN and HAVE_MEMALIGN undefined on an x86 Linux

e2fsck.conf.5: add buggy_init_scripts to the man page
We have renamed buggy_init_scripts to accept_time_fudge. Explain this
so that people who find buggy_init_scripts in older e2fsck.conf files
understand what is going on.

libext2fs: improve testing coverage of tst_bitmaps
Improve the test coverage of tst_bitmaps by:
(a) adding the ability to test the legacy (32-bit) bitmap code
(b) adding tests for ext2fs_find_first_zero_inode_bitmap2() and
ext2fs_find_first_zero_block_bitmap2()
The recent regressions caused by the addition (and use) of
ext2fs_find_first_zero_inode_bitmap2() would have been caught if we
had added these tests first. (Another object lesson in why unit tests
are critically important!)

libext2fs: use correct types in ext2fs_find_first_zero_block_bitmap2()
Fortunately nothing was using this inline function, so we'll just fix
the types in its function signature, which were nonsensical (this was
caused by a cut-and-paste error).

libext2fs: add 32-bit compat code for ext2fs_find_first_zero_generic_bmap()
The lack of 32-bit support was causing febootstrap to crash since it
wasn't passing EXT2_FLAG_64BITS when opening the file system, so we
were still using the legacy bitmaps.
Also add support for bigalloc bitmap into the ffz functions.

Don't assume that the presence of mntent.h means that setmntent() exists
Change autoconf to test for setmntent() and use that to decide whether
to use getmntent() and setmntent(), since some systems don't have
setmntent() but they do have the mntent.h header file.
Also, remove the includes of mntent.h from e2fsck and mke2fs and other
places where it is not needed.

mke2fs: don't fail creating the journal if /etc/mtab is missing
The ext2fs_add_journal_inode() function calls
ext2fs_check_mount_point(), which can fail if /etc/mtab is missing.
This causes mke2fs to fail in the middle of the file system format
process; mke2fs calls ext2fs_check_mount_point() already (and has
appropriate fallbacks that calls fails), so add a flag so that mke2fs
can request ext2fs_add_journal_inode() to skip trying to call
e2fsck_check_mount_point().
