Subject: [PATCH 17/46] Fix clang warnings
Content-Type: text/plain
Clang gets unhappy when passing an unsigned char to string functions.
For better or for worse we use __u8[] in the definition of the
superblock. So cast them these to "char *" to prevent clang
build-time warnings.

Subject: [PATCH 13/46] create_inode: set xattrs to the root directory as well
Content-Type: text/plain
populate_fs do copy the xattrs for all files and directories, but the
root directory is skipped and as a result its extended attributes aren't
set. This is an issue when using mkfs to build a full system image that
can be used with SElinux in enforcing mode without making any runtime
fix at first boot.
This patch adds logic to set the root directory's extended attributes.

Subject: [PATCH 05/46] e2fsck: fix indexed dir rehash failure with
metadata_csum enabled
Content-Type: text/plain
E2fsck directory rehashing code can fail with ENOSPC due to a bug in
ext2fs_htree_intnode_maxrecs() which fails to take metadata checksum
into account and thus e.g. e2fsck can decide to create 1 indirect level
of index tree when two are actually needed. Fix the logic to account for
metadata checksum.

Subject: [PATCH 26/46] e2fsck: fix last mount/write time when e2fsck is forced
Content-Type: text/plain
With commit c52d930f e2fsck is no longer able to fix bad last
mount/write time by default because it is conditioned on s_checkinterval
not being zero, which it is by default.
One place where it matters is when other e2fsprogs tools require to run
full file system check before a certain operation. If the last mount
time is for any reason in future, it will not allow it to run even if
full e2fsck is ran.
Fix it by checking the last mount/write time when the e2fsck is forced,
except for the case where we know the system clock is broken.
[ Reworked the conditionals so error messages claiming that the last
write/mount time were corrupted wouldn't be always printed when the
e2fsck was run with the -f option, thus causing 299 out of 372
regression tests to fail. -- TYT ]

it is possible to overflow offset at multiply operation.
This leads to the situation when data is written to the

Let's use the right cast to avoid integer overflow.

Subject: [PATCH 14/46] filefrag: handle invalid st_dev and blksize cases
Content-Type: text/plain
It is possible to crash filefrag with a "Floating point exception" in
two different scenarios:
1. When fstat() returns a device ID set to 0
2. When FIGETBSZ ioctl returns a blocksize of 0
In both scenarios a divide-by-zero will occur in frag_report() because
variable blksize will be set to zero.
I've managed to trigger this crash with an old CephFS kernel client,
using xfstest generic/519. The first scenario has been fixed by kernel
commit 75c9627efb72 ("ceph: map snapid to anonymous bdev ID"). The
second scenario is also fixed with commit 8f97d1e99149 ("vfs: fix
FIGETBSZ ioctl on an overlayfs file").
However, it is desirable to handle these two scenarios gracefully by
checking these conditions explicitly.

It is possible to have a corrupted extent tree in such a way that a leaf
node contains zero extents in it. Currently if that happens and we try
to traverse the tree we can end up accessing wrong data, or possibly
even uninitialized memory. Make sure we don't do that.
Additionally make sure that we have a sane number of bytes passed to
memmove() in ext2fs_extent_delete().
Note that e2fsck is currently unable to spot and fix such corruption in
pass1.

Subject: [PATCH 02/46] libext2fs: fix crash in ext2fs_image_super_write() on
Big Endian systems
Content-Type: text/plain
This is a similar fix as c9a8c53b17cc ("libext2fs: fix crash in
ext2fs_open2() on Big Endian systems").
Commit e6069a05: ("Teach ext2fs_open2() to honor the
EXT2_FLAG_SUPER_ONLY flag") changed how the function
ext2fs_group_desc() handled a request for a gdp pointer for a group
larger than the number of groups in the file system; it now returns
NULL, instead of returning a pointer beyond the end of the array.
Previously, the ext2fs_imager_super_write() function would swap all of
the block group descriptors in a block, even if they are beyond the
end of the file system. This was OK, since we were not overrunning
the allocated memory, since it was rounded to a block boundary. But
now that ext2fs_group_desc() would return NULL for those gdp, it would
cause ext2fs_open2(), when it was byte swapping the block group
descriptors on Big Endian systems, to dereference a null pointer and
crash.
This commit adds a NULL pointer check to avoid byte swapping those
block group descriptors in a bg descriptor block, but which are beyond
the end of the file system, to address this crash.

before MMP is initialized
Content-Type: text/plain
The fatal_error() function in e2fsck can call ext2fs_mmp_stop() on a
file system where MMP hasn't yet been initialized. When that happens,
instead of crashing, have ext2fs_mmp_stop() return success, since mmp
doesn't need to be stopped if it hasn't even been initialized yet.

If the file system is corrupted, there is a potential of a read-only

pointer dereference, and the overrun is at most 64k.

Subject: [PATCH 40/46] libext2fs: fix unexpected NULL variable
Content-Type: text/plain
The ext2fs_check_mount_point() function can be called with mtpt being
NULL as for example from ext2fs_check_if_mounted(). However in the
is_swap_device condition we use the mtpt in strncpy without checking
whether it is non-null first.
This should not be a problem on linux since the previous attempt to open
the device exclusively would have prevented us from ever reaching the
problematic strncpy. However it's still a bug and can cause problems on
other systems, fix it by conditioning strncpy on mtpt not being null.

Rbtree code was originally taken from linux kernel. This includes the
augmented rbtree functionality, however this was never intended to be
used and is not used still. Just remove it.

Subject: [PATCH 34/46] mke2fs: only try discarding a single block to test if
discard works
Content-Type: text/plain
Commit d2bfdc7ff15c ("Use punch hole as "discard" on regular files")
added a test to see if the storage device actually supports discard.
The intent was to try discarding the first block but since
io_channel_discard() interprets the offset and count arguments in
blocks, and not bytes, mke2fs was actually discarding the first 16
megabytes (when the block size is 4k). This is normally not a
problem, since most file systems are larger than that, and requests to
discard beyond the end of the block device are ignored.
However, when creating a small file system as part of a image
containing multiple partitions, the initial test discard can end up
discarding data beyond the file system being created.

Subject: [PATCH 23/46] mmp: do not use O_DIRECT when working with regular file
Content-Type: text/plain
Currently the mmp block is read using O_DIRECT to avoid any caching that
may be done by the VM. However when working with regular files this
creates alignment issues when the device of the host file system has
sector size larger than the blocksize of the file system in the file
we're working with.
This can be reproduced with t_mmp_fail test when run on the device with
4k sector size because the mke2fs fails when trying to read the mmp
block.
Fix it by disabling O_DIRECT when working with regular files. I don't
think there is any risk of doing so since the file system layer, unlike
shared block device, should guarantee cache consistency.

Subject: [PATCH 24/46] resize2fs: avoid allocating over the MMP block
Content-Type: text/plain
When resizing past the point where the reserve inode has reserved
space for the block group descriptors to expand, and resize2fs (in an
offline resize) needs to move the allocation bitmaps and/or inode
table around, it's possible for resize2fs to allocate over the MMP
block, which would be bad.
Prevent this from happening by reserving the MMP block as a file
system metadata block (which it is) in resize2fs's accounting.

For 1k block file systems, resizing a file system larger than

mke2fs -t ext4 /tmp/foo.img 200M
resize2fs /tmp/foo.img 1T
