ext2: Drop fragment support

2023-08-11T09:57:54+00:00

commit 404615d7f1dcd4cca200e9a7a9df3a1dcae1dd62 upstream. Ext2 has fields in superblock reserved for subblock allocation support. However that never landed. Drop the many years dead code.

ext2: Check block size validity during mount

2023-05-30T11:57:48+00:00

[ Upstream commit 62aeb94433fcec80241754b70d0d1836d5926b0a ] Check that log of block size stored in the superblock has sensible value. Otherwise the shift computing the block size can overflow leading to undefined behavior.

ext2: ext2.h: fix duplicated word + typos

2020-07-27T08:58:06+00:00

Change the repeated word "the" in "it the the" to "it is the". Fix typo "recentl" to "recently". Fix verb "give" to "gives". Link: https://lore.kernel.org/r/20200720001327.23603-1-rdunlap@infradead.org Signed-off-by: Randy Dunlap Cc: Jan Kara Cc: linux-ext4@vger.kernel.org Signed-off-by: Jan Kara

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. Link: https://lore.kernel.org/r/20191104114036.9893-1-cgxu519@mykernel.net Signed-off-by: Chengguang Xu Signed-off-by: Jan Kara

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

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. Reviewed-by: zhangyi (F) Signed-off-by: yangerkun Signed-off-by: Jan Kara

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 Signed-off-by: Amir Goldstein Signed-off-by: Phillip Potter Signed-off-by: Jan Kara

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. Signed-off-by: Chengguang Xu Signed-off-by: Jan Kara
