Suppose we issue two FITRIM ioctls for ranges [0,15] and [16,31] with
mininum length of trimmed range set to 8 blocks. If we have say a range of
blocks 10-22 free, this range will not be trimmed because it straddles the
boundary of the two FITRIM ranges and neither part is big enough. This is a
bit surprising to some users that call FITRIM on smaller ranges of blocks
to limit impact on the system. Also XFS trims all free space extents that
overlap with the specified range so we are inconsistent among filesystems.
Let's change ext4_try_to_trim_range() to consider for trimming the whole
free space extent that straddles the end of specified range, not just the
part of it within the range.

Currently in case the goal length is a multiple of stripe size we use
ext4_mb_scan_aligned() to find the stripe size aligned physical blocks.
In case we are not able to find any, we again go back to calling
ext4_mb_choose_next_group() to search for a different suitable block
group. However, since the linear search always begins from the start,
most of the times we end up with the same BG and the cycle continues.
With large fliesystems, the CPU can be stuck in this loop for hours
which can slow down the whole system. Hence, until we figure out a
better way to continue the search (rather than starting from beginning)
in ext4_mb_choose_next_group(), lets just fallback to
ext4_mb_complex_scan_group() in case aligned scan fails, as it is much
more likely to find the needed blocks.

The ext4 filesystem tracks the trim status of blocks at the group
level. When an entire group has been trimmed then it is marked as
such and subsequent trim invocations with the same minimum trim size
will not be attempted on that group unless it is marked as able to be
trimmed again such as when a block is freed.
Currently the last group can't be marked as trimmed due to incorrect
logic in ext4_last_grp_cluster(). ext4_last_grp_cluster() is supposed
to return the zero based index of the last cluster in a group. This is
then used by ext4_try_to_trim_range() to determine if the trim
operation spans the entire group and as such if the trim status of the
group should be recorded.
ext4_last_grp_cluster() takes a 0 based group index, thus the valid
values for grp are 0..(ext4_get_groups_count - 1). Any group index
less than (ext4_get_groups_count - 1) is not the last group and must
have EXT4_CLUSTERS_PER_GROUP(sb) clusters. For the last group we need
to calculate the number of clusters based on the number of blocks in
the group. Finally subtract 1 from the number of clusters as zero
based indexing is expected. Rearrange the function slightly to make
it clear what we are calculating and returning.
Reproducer:
// Create file system where the last group has fewer blocks than
// blocks per group
$ mkfs.ext4 -b 4096 -g 8192 /dev/nvme0n1 8191
$ mount /dev/nvme0n1 /mnt
Before Patch:
$ fstrim -v /mnt
/mnt: 25.9 MiB (27156480 bytes) trimmed
// Group not marked as trimmed so second invocation still discards blocks
$ fstrim -v /mnt
/mnt: 25.9 MiB (27156480 bytes) trimmed
After Patch:
fstrim -v /mnt

// Group marked as trimmed so second invocation DOESN'T discard any blocks

As an optimization, I was trying to work on exiting early from this
function if dealing with unwritten extent since they anyways read 0.
However, it was realised that there are certain code paths that can
end up calling ext4_block_zero_page_range() for an unwritten bh that
might still have data in pagecache. In this case, we can't exit early
and we do require to process the bh and zero out the pagecache to ensure
that a writeback can't kick in at a later time and flush the stale
pagecache to disk.
Since, adding the logic to exit early for unwritten bh was turning out
to be much more nuanced and the current code already handles it well,
just add a comment to explicitly document this behavior.

This is because flexbg_size is too large and the size of the new_group_data
array to be allocated exceeds MAX_ORDER. Currently, the minimum value of
MAX_ORDER is 8, the minimum value of PAGE_SIZE is 4096, the corresponding
maximum number of groups that can be allocated is:
(PAGE_SIZE << MAX_ORDER) / sizeof(struct ext4_new_group_data) ≈ 21845
And the value that is down-aligned to the power of 2 is 16384. Therefore,
this value is defined as MAX_RESIZE_BG, and the number of groups added
each time does not exceed this value during resizing, and is added multiple
times to complete the online resizing. The difference is that the metadata
in a flex_bg may be more dispersed.

The maximum value of flexbg_size is 2^31, but the maximum value of int
is (2^31 - 1), so overflow may occur when the type of flexbg_size is
declared as int.
For example, when uninit_mask is initialized in ext4_alloc_group_tables(),
if flexbg_size == 2^31, the initialized uninit_mask is incorrect, and this
may causes set_flexbg_block_bitmap() to trigger a BUG_ON().
Therefore, the flexbg_size type is declared as unsigned int to avoid
overflow and memory waste.

The syzbot has reported that it can hit the warning in
ext4_dio_write_end_io() because i_size < i_disksize. Indeed the
reproducer creates a race between DIO IO completion and truncate
expanding the file and thus ext4_dio_write_end_io() sees an inconsistent
inode state where i_disksize is already updated but i_size is not
updated yet. Since we are careful when setting up DIO write and consider
it extending (and thus performing the IO synchronously with i_rwsem held
exclusively) whenever it goes past either of i_size or i_disksize, we
can use the same test during IO completion without risking entering
ext4_handle_inode_extension() without i_rwsem held. This way we make it
obvious both i_size and i_disksize are large enough when we report DIO
completion without relying on unreliable WARN_ON.

ex.fe_logical = orig_goal_end - EXT4_C2B(sbi, ex.fe_len);
if (ac->ac_o_ex.fe_logical >= ex.fe_logical)
goto adjust_bex;
The problem is that when orig_goal_end is subtracted from ac_b_ex.fe_len
it is still greater than EXT_MAX_BLOCKS, which causes ex.fe_logical to
overflow to a very small value, which ultimately triggers a BUG_ON in
ext4_mb_new_inode_pa() because pa->pa_free < len.
The last logical block of an actual write request does not exceed
EXT_MAX_BLOCKS, so in ext4_mb_normalize_request() also avoids normalizing
the last logical block to exceed EXT_MAX_BLOCKS to avoid the above issue.
The test case in [Link] can reproduce the above issue with 64k block size.

Merge tag 'parisc-for-6.7-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux
Pull parisc architecture fixes from Helge Deller:
"This patchset fixes and enforces correct section alignments for the
ex_table, altinstructions, parisc_unwind, jump_table and bug_table
which are created by inline assembly.
Due to not being correctly aligned at link & load time they can
trigger unnecessarily the kernel unaligned exception handler at
runtime. While at it, I switched the bug table to use relative
addresses which reduces the size of the table by half on 64-bit.
We still had the ENOSYM and EREMOTERELEASE errno symbols as left-overs
from HP-UX, which now trigger build-issues with glibc. We can simply
remove them.
Most of the patches are tagged for stable kernel series.
Summary:
- Drop HP-UX ENOSYM and EREMOTERELEASE return codes to avoid glibc
build issues
- Fix section alignments for ex_table, altinstructions, parisc unwind
table, jump_table and bug_table
- Reduce size of bug_table on 64-bit kernel by using relative

* tag 'parisc-for-6.7-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux:

parisc: Drop the HP-UX ENOSYM and EREMOTERELEASE error codes
parisc: Use natural CPU alignment for bug_table
parisc: Ensure 32-bit alignment on parisc unwind section
parisc: Mark lock_aligned variables 16-byte aligned on SMP

Merge tag 'vfs-6.7-rc3.fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs
Pull vfs fixes from Christian Brauner:
- Avoid calling back into LSMs from vfs_getattr_nosec() calls.
IMA used to query inode properties accessing raw inode fields without
dedicated helpers. That was finally fixed a few releases ago by
forcing IMA to use vfs_getattr_nosec() helpers.
The goal of the vfs_getattr_nosec() helper is to query for attributes
without calling into the LSM layer which would be quite problematic
because incredibly IMA is called from __fput()...
__fput()
-> ima_file_free()
What it does is to call back into the filesystem to update the file's
IMA xattr. Querying the inode without using vfs_getattr_nosec() meant
that IMA didn't handle stacking filesystems such as overlayfs
correctly. So the switch to vfs_getattr_nosec() is quite correct. But
the switch to vfs_getattr_nosec() revealed another bug when used on
stacking filesystems:
__fput()
-> ima_file_free()
-> vfs_getattr_nosec()
-> i_op->getattr::ovl_getattr()
-> vfs_getattr()
-> i_op->getattr::$WHATEVER_UNDERLYING_FS_getattr()
-> security_inode_getattr() # calls back into LSMs
Now, if that __fput() happens from task_work_run() of an exiting task
current->fs and various other pointer could already be NULL. So
anything in the LSM layer relying on that not being NULL would be
quite surprised.
Fix that by passing the information that this is a security request
through to the stacking filesystem by adding a new internal
ATT_GETATTR_NOSEC flag. Now the callchain becomes:
__fput()
-> ima_file_free()
-> vfs_getattr_nosec()
-> i_op->getattr::ovl_getattr()
-> if (AT_GETATTR_NOSEC)
vfs_getattr_nosec()
else
vfs_getattr()
-> i_op->getattr::$WHATEVER_UNDERLYING_FS_getattr()
- Fix a bug introduced with the iov_iter rework from last cycle.
This broke /proc/kcore by copying too much and without the correct
offset.
- Add a missing NULL check when allocating the root inode in
autofs_fill_super().
- Fix stable writes for multi-device filesystems (xfs, btrfs etc) and
the block device pseudo filesystem.
Stable writes used to be a superblock flag only, making it a per
filesystem property. Add an additional AS_STABLE_WRITES mapping flag
to allow for fine-grained control.
- Ensure that offset_iterate_dir() returns 0 after reaching the end of
a directory so it adheres to getdents() convention.
