fs: fix FAT name extraction

2018-12-07T04:26:31Z

The long name apparently can be accumulated using multiple 13-byte slots. Unfortunately we never checked how many we can actually fit in the buffer we are reading to. Signed-off-by: Patrick Wildt

fs: check FAT cluster size

2018-12-07T04:26:31Z

The cluster size specifies how many sectors make up a cluster. A cluster size of zero makes no sense, as it would mean that the cluster is made up of no sectors. This will later lead into a division by zero in sect_to_clust(), so better take care of that early. The MAX_CLUSTSIZE define can reduced using a define to make some room in low-memory system. Unfortunately if the code reads a filesystem with a bigger cluster size it will overflow the buffer. Signed-off-by: Patrick Wildt

fs: update fs_dev_part in fs_set_blk_dev_with_part()

2018-12-02T20:59:36Z

As in the case of fs_set_blk_dev(), fs_set_blk_dev_with_part() should maintain and update fs_dev_part whenever called. Without this patch, a problem will come up when an efi binary associated with efi's BOOTxxxx variable is invoked via "bootefi bootmgr". Signed-off-by: AKASHI Takahiro Signed-off-by: Alexander Graf

fs: Makefile: Add fs.c under SPL for fs_loader

fs: ubifs: Fix UBIFS decompression on 64 bit

2018-11-07T07:49:27Z

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. Signed-off-by: Paul Davey Cc: Heiko Schocher Tested-by: Heiko Schocher

fs: btrfs: Fix tree traversal with btrfs_next_slot()

2018-10-08T18:45:02Z

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: fat: fix set_cluster()

2018-10-06T18:09:41Z
