4b71928e5c f2fs: fix to unmap pages from userspace process in punch_hole()
[ Upstream commit c8dc3047c48540183744f959412d44b08c5435e1 ]

We need to unmap pages from userspace process before removing pagecache
in punch_hole() like we did in f2fs_setattr().

Similar change:
commit 5e44f8c374 ("ext4: hole-punch use truncate_pagecache_range")

611b7f9dc9 f2fs: guarantee to write dirty data when enabling checkpoint back
commit dddd3d65293a52c2c3850c19b1e5115712e534d8 upstream.

We must flush all the dirty data when enabling checkpoint back. Let's guarantee
that first by adding a retry logic on sync_inodes_sb(). In addition to that,
this patch adds to flush data in fsync when checkpoint is disabled, which can
mitigate the sync_inodes_sb() failures in advance.

b5a393c8a8 f2fs: logging neatening
Update the logging uses that have unnecessary newlines as the f2fs_printk
function and so its f2fs_<level> macro callers already adds one.

This allows searching single line logging entries with an easier grep and
also avoids unnecessary blank lines in the logging.

Miscellanea:

o Coalesce formats
o Align to open parenthesis

3134ed20c7 f2fs: introduce FI_COMPRESS_RELEASED instead of using IMMUTABLE bit
Once we release compressed blocks, we used to set IMMUTABLE bit. But it turned
out it disallows every fs operations which we don't need for compression.

Let's just prevent writing data only.

e79067da34 f2fs: compress: remove unneeded preallocation
We will reserve iblocks for compression saved, so during compressed
cluster overwrite, we don't need to preallocate blocks for later
write.

In addition, it adds a bug_on to detect wrong reserved iblock number
in __f2fs_cluster_blocks().

Bug fix in the original patch by Jaegeuk:
If we released compressed blocks having an immutable bit, we can see less
number of compressed block addresses. Let's fix wrong BUG_ON.

err is only set if there is some work to do.  Because the loop returns

[ Upstream commit e1175f02291141bbd924fc578299305fcde35855 ]

Now, fallocate() on a pinned file only allocates blocks which aligns
to segment rather than section, so GC may try to migrate pinned file's

[ Upstream commit 34178b1bc4b5c936eab3adb4835578093095a571 ]

Eric reported a ioctl bug in below link:

https://lore.kernel.org/linux-f2fs-devel/20201103032234.GB2875@sol.localdomain/

That said, on some 32-bit architectures, u64 has only 32-bit alignment,
notably i386 and x86_32, so that size of struct f2fs_gc_range compiled
in x86_32 is 20 bytes, however the size in x86_64 is 24 bytes, binary
compiled in x86_32 can not call F2FS_IOC_GARBAGE_COLLECT_RANGE successfully
due to mismatched value of ioctl command in between binary and f2fs
module, similarly, F2FS_IOC_MOVE_RANGE will fail too.

In this patch we introduce two ioctls for compatibility of above special
32-bit binary:
- F2FS_IOC32_GARBAGE_COLLECT_RANGE
- F2FS_IOC32_MOVE_RANGE

04a495780f f2fs: enforce the immutable flag on open files
commit e0fcd01510ad025c9bbce704c5c2579294056141 upstream.

This patch ports commit 02b016ca7f ("ext4: enforce the immutable
flag on open files") to f2fs.

According to the chattr man page, "a file with the 'i' attribute
cannot be modified..."  Historically, this was only enforced when the
file was opened, per the rest of the description, "... and the file
can not be opened in write mode".

There is general agreement that we should standardize all file systems
to prevent modifications even for files that were opened at the time
the immutable flag is set.  Eventually, a change to enforce this at
the VFS layer should be landing in mainline.

The root cause is:
If we open file w/ readonly flag, disk quota info won't be initialized
for this file, however, following mmap() will force to convert inline
inode via f2fs_convert_inline_inode(), which may increase block usage
for this inode w/o updating quota data, it causes inconsistent disk quota
info.

The issue will happen in following stack:
open(file, O_RDONLY)
mmap(file)
- f2fs_convert_inline_inode
 - f2fs_convert_inline_page
  - f2fs_reserve_block
   - f2fs_reserve_new_block
    - f2fs_reserve_new_blocks
     - f2fs_i_blocks_write
      - dquot_claim_block
inode->i_blocks increase, but the dqb_curspace keep the size for the dquots
is NULL.

To fix this issue, let's call dquot_initialize() anyway in both
f2fs_truncate() and f2fs_convert_inline_inode() functions to avoid potential
inconsistent quota data issue.

d758f50680 fs-verity: add FS_IOC_READ_VERITY_METADATA ioctl
Add an ioctl FS_IOC_READ_VERITY_METADATA which will allow reading verity
metadata from a file that has fs-verity enabled, including:

- The Merkle tree
- The fsverity_descriptor (not including the signature if present)
- The built-in signature, if present

This ioctl has similar semantics to pread().  It is passed the type of
metadata to read (one of the above three), and a buffer, offset, and
size.  It returns the number of bytes read or an error.

Separate patches will add support for each of the above metadata types.
This patch just adds the ioctl itself.

This ioctl doesn't make any assumption about where the metadata is
stored on-disk.  It does assume the metadata is in a stable format, but
that's basically already the case:

- The Merkle tree and fsverity_descriptor are defined by how fs-verity
  file digests are computed; see the "File digest computation" section
  of Documentation/filesystems/fsverity.rst.  Technically, the way in
  which the levels of the tree are ordered relative to each other wasn't
  previously specified, but it's logical to put the root level first.

- The built-in signature is the value passed to FS_IOC_ENABLE_VERITY.

This ioctl is useful because it allows writing a server program that
takes a verity file and serves it to a client program, such that the
client can do its own fs-verity compatible verification of the file.
This only makes sense if the client doesn't trust the server and if the
server needs to provide the storage for the client.

More concretely, there is interest in using this ability in Android to
export APK files (which are protected by fs-verity) to "protected VMs".
This would use Protected KVM (https://lwn.net/Articles/836693), which
provides an isolated execution environment without having to trust the
traditional "host".  A "guest" VM can boot from a signed image and
perform specific tasks in a minimum trusted environment using files that
have fs-verity enabled on the host, without trusting the host or
requiring that the guest has its own trusted storage.

Technically, it would be possible to duplicate the metadata and store it
in separate files for serving.  However, that would be less efficient
and would require extra care in userspace to maintain file consistency.

In addition to the above, the ability to read the built-in signatures is
useful because it allows a system that is using the in-kernel signature
verification to migrate to userspace signature verification.

[FSCK] fixing SIT types
[FSCK] other corrupted bugs                           [Fail]

The root cause is:
If we open file w/ readonly flag, disk quota info won't be initialized
for this file, however, following mmap() will force to convert inline
inode via f2fs_convert_inline_inode(), which may increase block usage
for this inode w/o updating quota data, it causes inconsistent disk quota
info.

The issue will happen in following stack:
open(file, O_RDONLY)
mmap(file)
- f2fs_convert_inline_inode
 - f2fs_convert_inline_page
  - f2fs_reserve_block
   - f2fs_reserve_new_block
    - f2fs_reserve_new_blocks
     - f2fs_i_blocks_write
      - dquot_claim_block
inode->i_blocks increase, but the dqb_curspace keep the size for the dquots
is NULL.

To fix this issue, let's call dquot_initialize() anyway in both
f2fs_truncate() and f2fs_convert_inline_inode() functions to avoid potential
inconsistent quota data issue.

3dabc6f5d3 f2fs: enforce the immutable flag on open files
This patch ports commit 02b016ca7f ("ext4: enforce the immutable
flag on open files") to f2fs.

According to the chattr man page, "a file with the 'i' attribute
cannot be modified..."  Historically, this was only enforced when the
file was opened, per the rest of the description, "... and the file
can not be opened in write mode".

There is general agreement that we should standardize all file systems
to prevent modifications even for files that were opened at the time
the immutable flag is set.  Eventually, a change to enforce this at
the VFS layer should be landing in mainline.

dd6d813fa2 f2fs: fix to set inode->i_mode correctly for posix_acl_update_mode
We should update the ~S_IRWXUGO part of inode->i_mode in __setattr_copy,
because posix_acl_update_mode updates mode based on inode->i_mode,
which finally overwrites the ~S_IRWXUGO part of i_acl_mode with old i_mode.

Testcase to reproduce this bug:
0. adduser abc
1. mkfs.f2fs /dev/sdd
2. mount -t f2fs /dev/sdd /mnt/f2fs
3. mkdir /mnt/f2fs/test
4. setfacl -m u🔤r /mnt/f2fs/test

7bf39237aa f2fs: fix compat F2FS_IOC_{MOVE,GARBAGE_COLLECT}_RANGE
Eric reported a ioctl bug in below link:

https://lore.kernel.org/linux-f2fs-devel/20201103032234.GB2875@sol.localdomain/

That said, on some 32-bit architectures, u64 has only 32-bit alignment,
notably i386 and x86_32, so that size of struct f2fs_gc_range compiled
in x86_32 is 20 bytes, however the size in x86_64 is 24 bytes, binary
compiled in x86_32 can not call F2FS_IOC_GARBAGE_COLLECT_RANGE successfully
due to mismatched value of ioctl command in between binary and f2fs
module, similarly, F2FS_IOC_MOVE_RANGE will fail too.

In this patch we introduce two ioctls for compatibility of above special
32-bit binary:
- F2FS_IOC32_GARBAGE_COLLECT_RANGE
- F2FS_IOC32_MOVE_RANGE
