ext4: fix scheduling in atomic on group checksum failure

2016-02-12T04:15:12Z

When block group checksum is wrong, we call ext4_error() while holding group spinlock from ext4_init_block_bitmap() or ext4_init_inode_bitmap() which results in scheduling while in atomic. Fix the issue by calling ext4_error() later after dropping the spinlock.

ext4: make the bitmap read routines return real error codes

2015-10-18T01:33:24Z

Make the bitmap reaading routines return real error codes (EIO, EFSCORRUPTED, EFSBADCRC) which can then be reflected back to userspace for more precise diagnosis work. In particular, this means that mballoc no longer claims that we're out of memory if the block bitmaps become corrupt. Signed-off-by: Darrick J. Wong Signed-off-by: Theodore Ts'o

ext4: clean up feature test macros with predicate functions

2015-10-17T20:18:43Z

Create separate predicate functions to test/set/clear feature flags, thereby replacing the wordy old macros. Furthermore, clean out the places where we open-coded feature tests. Signed-off-by: Darrick J. Wong

ext4: call out CRC and corruption errors with specific error codes

2015-10-17T20:16:04Z

Instead of overloading EIO for CRC errors and corrupt structures, return the same error codes that XFS returns for the same issues. Signed-off-by: Darrick J. Wong Signed-off-by: Theodore Ts'o

ext4: Handle error from dquot_initialize()

ext4 crypto: encrypt tmpfile located in encryption protected directory

2015-05-31T17:35:02Z

Factor out calls to ext4_inherit_context() and move them to __ext4_new_inode(); this fixes a problem where ext4_tmpfile() wasn't calling calling ext4_inherit_context(), so the temporary file wasn't getting protected. Since the blocks for the tmpfile could end up on disk, they really should be protected if the tmpfile is created within the context of an encrypted directory. Signed-off-by: Theodore Ts'o

ext4: clean up superblock encryption mode fields

2015-05-18T17:18:47Z

The superblock fields s_file_encryption_mode and s_dir_encryption_mode are vestigal, so remove them as a cleanup. While we're at it, allow file systems with both encryption and inline_data enabled at the same time to work correctly. We can't have encrypted inodes with inline data, but there's no reason to prohibit unencrypted inodes from using the inline data feature. Signed-off-by: Theodore Ts'o
