On 32-bit architectures, unsigned long is only 32 bits wide, which
causes 64-bit inode numbers to be silently truncated. Several
filesystems (NFS, XFS, BTRFS, etc.) can generate inode numbers that
exceed 32 bits, and this truncation can lead to inode number collisions
and other subtle bugs on 32-bit systems.
Change the type of inode->i_ino from unsigned long to u64 to ensure that
inode numbers are always represented as 64-bit values regardless of
architecture. Update all format specifiers treewide from %lu/%lx to
%llu/%llx to match the new type, along with corresponding local variable
types.
This is the bulk treewide conversion. Earlier patches in this series
handled trace events separately to allow trace field reordering for
better struct packing on 32-bit.

Pull f2fs updates from Jaegeuk Kim:
"In this development cycle, we focused on several key performance
optimizations:
- introducing large folio support to enhance read speeds for
immutable files
- reducing checkpoint=enable latency by flushing only committed dirty
pages
- implementing tracepoints to diagnose and resolve lock priority
inversion.
Additionally, we introduced the packed_ssa feature to optimize the SSA
footprint when utilizing large block sizes.
Detail summary:
Enhancements:
- support large folio for immutable non-compressed case
- support non-4KB block size without packed_ssa feature
- optimize f2fs_enable_checkpoint() to avoid long delay
- optimize f2fs_overwrite_io() for f2fs_iomap_begin
- optimize NAT block loading during checkpoint write
- add write latency stats for NAT and SIT blocks in
f2fs_write_checkpoint
- pin files do not require sbi->writepages lock for ordering
- avoid f2fs_map_blocks() for consecutive holes in readpages
- flush plug periodically during GC to maximize readahead effect
- add tracepoints to catch lock overheads
- add several sysfs entries to tune internal lock priorities
Fixes:
- fix lock priority inversion issue
- fix incomplete block usage in compact SSA summaries
- fix to show simulate_lock_timeout correctly
- fix to avoid mapping wrong physical block for swapfile
- fix IS_CHECKPOINTED flag inconsistency issue caused by
concurrent atomic commit and checkpoint writes
- fix to avoid UAF in f2fs_write_end_io()"

If FI_ATOMIC_DIRTIED is not set, atomic file can encounter corruption
due to a mismatch between old file size and new data.
To resolve this issue, I changed to set FI_ATOMIC_DIRTIED when
FI_DIRTY_INODE is set. This ensures that FI_DIRTY_INODE, which was
previously cleared by the Writeback thread during the commit atomic, is
set and i_size is updated.

UBSAN detects that inline_xattr_addr() tries to access .i_addr[-1125].
w/ below testcase, it can reproduce this bug easily:
- mkfs.f2fs -f -O extra_attr,flexible_inline_xattr /dev/sdb
- mount -o inline_xattr_size=512 /dev/sdb /mnt/f2fs
- touch /mnt/f2fs/file
- umount /mnt/f2fs
- inject.f2fs --node --mb i_inline --nid 4 --val 0x1 /dev/sdb
- inject.f2fs --node --mb i_inline_xattr_size --nid 4 --val 2048 /dev/sdb
- mount /dev/sdb /mnt/f2fs
- getfattr /mnt/f2fs/file
The root cause is if metadata of filesystem and inode were fuzzed as below:
- extra_attr feature is enabled
- flexible_inline_xattr feature is enabled
- ri.i_inline_xattr_size = 2048
- F2FS_EXTRA_ATTR bit in ri.i_inline was not set
sanity_check_inode() will skip doing sanity check on fi->i_inline_xattr_size,
result in using invalid inline_xattr_size later incorrectly, fix it.
Meanwhile, let's fix to check lower boundary for .i_inline_xattr_size w/
MIN_INLINE_XATTR_SIZE like we did in parse_options().
There is a related issue reported by syzbot, Qasim Ijaz has anlyzed and
fixed it w/ very similar way [1], as discussed, we all agree that it will
be better to do sanity check in sanity_check_inode() for fix, so finally,
let's fix these two related bugs w/ current patch.
Including commit message from Qasim's patch as below, thanks a lot for
his contribution.
"In f2fs_getxattr(), the function lookup_all_xattrs() allocates a 12-byte
(base_size) buffer for an inline extended attribute. However, when
__find_inline_xattr() calls __find_xattr(), it uses the macro
"list_for_each_xattr(entry, addr)", which starts by calling
XATTR_FIRST_ENTRY(addr). This skips a 24-byte struct f2fs_xattr_header
at the beginning of the buffer, causing an immediate out-of-bounds read
in a 12-byte allocation. The subsequent !IS_XATTR_LAST_ENTRY(entry)
check then dereferences memory outside the allocated region, triggering
the slab-out-of bounds read.
This patch prevents the out-of-bounds read by adding a check to bail
out early if inline_size is too small and does not account for the
header plus the 4-byte value that IS_XATTR_LAST_ENTRY reads."

The root cause is: creating large files during disable checkpoint
period results in not enough free segments, so when writing back root
inode will failed in f2fs_enable_checkpoint. When umount the file
system after enabling checkpoint, the root inode is dirty in
f2fs_evict_inode function, which triggers BUG_ON. The steps to
reproduce are as follows:
dd if=/dev/zero of=f2fs.img bs=1M count=55
mount f2fs.img f2fs_dir -o checkpoint=disable:10%
dd if=/dev/zero of=big bs=1M count=50
