2020-04-27fs: ext4: skip journal state if fs has metadata_csumArnaud Ferraris
As u-boot doesn't support the metadata_csum feature, writing to a filesystem with this feature enabled will fail, as expected. However, during the process, a journal state check is performed, which could result in: - a fs recovery if the fs wasn't umounted properly - the fs being marked dirty Both these cases result in a superblock change, leading to a mismatch between the superblock checksum and its contents. Therefore, Linux will consider the filesystem heavily corrupted and will require e2fsck to be run manually to boot. By bypassing the journal state check, this patch ensures the superblock won't be corrupted if the filesystem has metadata_csum feature enabled.

2020-04-16fs: btrfs: Fix LZO false decompression error caused by pending zeroQu Wenruo
For certain btrfs files with compressed file extent, uboot will fail to load it: btrfs_read_extent_reg: disk_bytenr=14229504 disk_len=73728 offset=0 nr_bytes=131 072 decompress_lzo: tot_len=70770 decompress_lzo: in_len=1389 decompress_lzo: in_len=2400 decompress_lzo: in_len=3002 decompress_lzo: in_len=1379 decompress_lzo: in_len=88539136 decompress_lzo: header error, in_len=88539136 clen=65534 tot_len=62580 NOTE: except the last line, all other lines are debug output. Btrfs lzo compression uses its own format to record compressed size (segment header, LE32). However to make decompression easier, we never put such segment header across page boundary. In above case, the xxd dump of the lzo compressed data looks like this: 00001fe0: 4cdc 02fc 0bfd 02c0 dc02 0d13 0100 0001 L............... 00001ff0: 0000 0008 0300 0000 0000 0011 0000|0000 ................ 00002000: 4705 0000 0001 cc02 0000 0000 0000 1e01 G............... '|' is the "expected" segment header start position. But in that page, there are only 2 bytes left, can't contain the 4 bytes segment header. So btrfs compression will skip that 2 bytes, put the segment header in next page directly. Uboot doesn't have such check, and read the header with 2 bytes offset, result 0x05470000 (88539136), other than the expected result 0x00000547 (1351), resulting above error. Follow the btrfs-progs restore implementation, by introducing tot_in to record total processed bytes (including headers), and do proper page boundary skip to fix it. Please note that, current code base doesn't parse fs_info thus we can't grab sector size easily, so it uses PAGE_SIZE, and relying on fs open time check to exclude unsupported sector size.

2020-04-16fs: btrfs: Reject fs with sector size other than PAGE_SIZEQu Wenruo
Although in theory u-boot fs driver could easily support more sector sizes, current code base doesn't have good enough way to grab sector size yet. This would cause problem for later LZO fixes which rely on sector size. And considering that most u-boot boards are using 4K page size, which is also the most common sector size for btrfs, rejecting fs with non-page-sized sector size shouldn't cause much problem. This should only be a quick fix before we implement better sector size support.

ext_cache_read doesn't null cache->buf, after freeing, which results in a later function double-freeing it. This patch fixes ext_cache_read to call ext_cache_fini instead of free. Signed-off-by: Paul Emge <paulemge@forallsecure.com>
2019-07-18ext4: add support for filesystems without JOURNALMarek Szyprowski
JOURNAL is optional for EXT4 (and EXT3) filesystems, so add support for skipping it. This fixes corrupting EXT4 volumes without JOURNAL after using uboot's 'ext4write' command. Signed-off-by: Marek Szyprowski <m.szyprowski@samsung.com> Reviewed-by: Lukasz Majewski <lukma@denx.de>
2019-07-18ext4: fix calculating inode blkcount for non-512 blocksize filesystemsMarek Szyprowski
The block count entry in the EXT4 filesystem disk structures uses standard 512-bytes units for most of the typical files. The only exception are HUGE files, which use the filesystem block size, but those are not supported by uboot's EXT4 implementation anyway. This patch fixes the EXT4 code to use proper unit count for inode block count. This fixes errors reported by fsck.ext4 on disks with non-standard (i.e. 4KiB, in case of new flash drives) PHYSICAL block size after using 'ext4write' uboot's command.

2019-06-20fs: do_load: pass device path for efi payloadMian Yousaf Kaukab
fatload command can be used to load the EFI payload since EFI system partition is always a FAT partition. Call into EFI code from do_load() to set the device path from which the last binary was loaded. An EFI application like grub2 can’t find its configuration file without the device path set. Since device path is now set in do_load() there is no need to set it in do_load_wrapper() for the load command.

2019-05-28fs: fat: allocate a new cluster for root directory of fat32AKASHI Takahiro
Contrary to fat12/16, fat32 can have root directory at any location and its size can be expanded. Without this patch, root directory won't grow properly and so we will eventually fail to add files under root directory. Please note that this can happen even if you delete many files as deleted directory entries are not reclaimed but just marked as "deleted" under the current implementation.

2019-05-28fs: fat: flush a directory cluster properlyAKASHI Takahiro
When a long name directory entry is created, multiple directory entries may be occupied across a directory cluster boundary. Since only one directory cluster is cached in a directory iterator, a first cluster must be written back to device before switching over a second cluster. Without this patch, some added files may be lost even if you don't see any failures on write operation.

2019-05-03fs: btrfs: fix btrfs methods return values on failureMarek Behún
The btrfs implementation methods .ls(), .size() and .read() returns 1 on failure, but the command handlers expect values <0 on failure. For example if given a nonexistent path, the load command currently returns success, and hush scripting does not work. Fix this by setting return values of these methods to -1 instead of 1 on failure. Signed-off-by: Marek Behún <marek.behun@nic.cz>

2019-04-26fs: btrfs: fix btrfs_search_tree invalid resultsPierre Bourdon
btrfs_search_tree should return the first item in the tree that is greater or equal to the searched item. The search algorithm did not properly handle the edge case where the searched item is higher than the last item of the node but lower than the first item of the next node. Instead of properly returning the first item of the next node, it was returning an invalid path pointer (pointing to a non-existent item after the last item of the node + 1). This fixes two issues in the btrfs driver: - Looking for a ROOT_ITEM could fail if it was the first item of its leaf node. - Iterating through DIR_INDEX entries (for readdir) could fail if the first DIR_INDEX entry was the first item of a leaf node.
