fs: make helpers idmap mount aware

2021-01-24T13:27:20+00:00

Extend some inode methods with an additional user namespace argument. A
filesystem that is aware of idmapped mounts will receive the user
namespace the mount has been marked with. This can be used for
additional permission checking and also to enable filesystems to
translate between uids and gids if they need to. We have implemented all
relevant helpers in earlier patches.

As requested we simply extend the exisiting inode method instead of
introducing new ones. This is a little more code churn but it's mostly
mechanical and doesnt't leave us with additional inode methods.

fs/ext2: Use ext2_put_page

2020-11-13T10:19:30+00:00

There are 3 places in namei.c where the equivalent of ext2_put_page() is
open coded on a page which was returned from the ext2_get_page() call
[through the use of ext2_find_entry() and ext2_dotdot()].

Move ext2_put_page() to ext2.h and use it in namei.c

Also add a comment regarding the proper way to release the page returned
from ext2_find_entry() and ext2_dotdot().

ext2: propagate errors up to ext2_find_entry()'s callers

2020-07-09T06:14:00+00:00

The same to commit <36de928641ee4> (ext4: propagate errors up to
ext4_find_entry()'s callers') in ext4, also return error instead of NULL
pointer in case of some error happens in ext2_find_entry() (e.g. -ENOMEM
or -EIO). This could avoid a negative dentry cache entry installed even
it failed to read directory block due to IO error.

ext2: introduce new helper ext2_group_last_block_no()

2019-11-06T15:25:12+00:00

Introduce new helper ext2_group_last_block_no() to calculate
last block num for specific block group, we can replace open
coded logic by calling this common helper.

Merge tag 'fs_for_v5.1-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/jack/linux-fs

2019-03-07T17:01:33+00:00

Pull ext2 and udf fixes from Jan Kara:
 "A couple of fixes for udf and ext2. Namely:

   - fix making ext2 mountable (again) with 64k blocksize

   - fix for ext2 statx(2) handling

   - fix for udf handling of corrupted filesystem so that it doesn't get
     corrupted even further

   - couple smaller ext2 and udf cleanups"

* tag 'fs_for_v5.1-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/jack/linux-fs:
  udf: Drop pointless check from udf_sync_fs()
  ext2: support statx syscall
  udf: disallow RW mount without valid integrity descriptor
  udf: finalize integrity descriptor before writeback
  udf: factor out LVID finalization for reuse
  ext2: Fix underflow in ext2_max_size()
  ext2: Fix a typo in comment
  ext2: Remove redundant check for finding no group
  ext2: Annotate implicit fall through in __ext2_truncate_blocks
  ext2: Set superblock revision when enabling xattr feature
  ext2: Remove redundant check on s_inode_size
  ext2: set proper return code

ext2: support statx syscall

2019-02-18T14:14:43+00:00

Since statx, every filesystem should fill the attributes/attributes_mask
in routine getattr. But the generic_fillattr has not fill that, so add
ext2_getattr to do this. This can fix generic/424 while testing ext2.

ext2: use common file type conversion

2019-01-21T16:48:17+00:00

Deduplicate the ext2 file type conversion implementation and remove
EXT2_FT_* definitions - file systems that use the same file types as
defined by POSIX do not need to define their own versions and can
use the common helper functions decared in fs_types.h and implemented
in fs_types.c

ext2: remove redundant building macro check

2018-09-24T19:34:15+00:00

If macro CONFIG_QUOTA is not enabled then mount option flag
of usrquota/grpquota will not be set, so we can remove some
building macro check safely in ext2_shwo_options().
Additionally, I think it's better to define EXT2_MOUNT_DAX
regardless macro CONFIG_FS_DAX is enabled just like acl/xattr.
