fs: ubifs: Fix UBIFS decompression on 64 bit

2018-11-07T07:49:27+00:00

Add local size_t variable to crypto_comp_decompress as intermediate
storage for destination length to avoid memory corruption and incorrect
results on 64 bit targets.

This is what linux does for the various lz compression implementations.

fs: btrfs: Fix tree traversal with btrfs_next_slot()

2018-10-08T18:45:02+00:00

When traversing slots in a btree (via btrfs_path) with btrfs_next_slot(),
we didn't correctly identify that the last slot in the leaf was reached
and we should jump to the next leaf.

This could lead to any kind of runtime errors or corruptions, like:
* file data not being read at all, or is read partially
* file is read but is corrupted
* (any) metadata being corrupted or not read at all, etc

The easiest way to reproduce this is to read a large enough file that
its EXTENT_DATA items don't fit into a single leaf.

fs: btrfs: Fix cache alignment bugs

2018-09-30T17:00:37+00:00

The btrfs implementation passes cache-unaligned buffers into the
block layer, which triggers cache alignment problems down in the
block device drivers. Align the buffers to prevent this.

fs: fat: unaligned buffers are not an error

2018-09-23T19:55:30+00:00

The FAT driver supports unaligned reads and writes and EFI applications
will make use of these. So a misaligned buffer is only worth a debug
message.

fs: fat: support unlink

2018-09-23T19:55:30+00:00

In this patch, unlink support is added to FAT file system.
A directory can be deleted only if it is empty.

In this implementation, only a directory entry for a short file name
will be removed. So entries for a long file name can and should be
reclaimed with fsck.
