This version of btrfs_file_read() has the following new features: - Tries all mirrors - More handling on unaligned size - Better compressed extent handling The old implementation doesn't handle compressed extent with offset properly: we need to read out the whole compressed extent, then decompress the whole extent, and only then copy the requested part.

Use extent buffer based infrastructure to re-implement btrfs_readdir(). Along this rework, some small corner cases fixed: - Subvolume tree mtime Mtime of a subvolume tree is recorded in its root item, since there is no INODE_ITEM for it. This needs extra search from tree root. - Output the unknown type If the DIR_ITEM is corrupted, at least don't try to access the memory out of boundary.

2020-09-07fs: btrfs: Implement btrfs_lookup_path()Qu Wenruo3-0/+360
This is the extent buffer based path lookup routine. To implement this, btrfs_lookup_dir_item() is crossported from btrfs-progs, and implements btrfs_lookup_path() from scratch. Unlike the existing __btrfs_lookup_path(), since btrfs_read_fs_root() will check whether a root is a orphan at read time, there is no need to check root backref, this makes the code a little easier to read.

All existing next_length() caller handles return value > BTRFS_NAME_LEN, so there is no need to do BTRFS_NAME_LEN check in next_length(). But still, we want to exit early if we're beyond BTRFS_NAME_LEN, so this patch makes next_length() exit as soon as we're beyond BTRFS_NAME_LEN.

2020-09-07fs: btrfs: Crossport open_ctree_fs_info() from btrfs-progsQu Wenruo8-20/+579
open_ctree_fs_info() is the main entry point to open btrfs. This version is a simplfied version of __open_ctree_fd() of btrfs-progs, the main differences are: - Parameters on how to specify a block device Instead of @fd and @path, U-Boot uses blk_desc and disk_partition_t. - Remove open_ctree flags There won't be multiple open ctree modes in U-Boot. Otherwise functions structures are all kept the same. With open_ctree_fs_info() implemented, also introduce the global current_fs_info pointer to show the current opened btrfs.

This version has the following functionality removed: - The ability to COW tree block Related code is commented out, and can be enabled in the future. - The readahead functionality This is abused in kernel.

2020-09-07fs: btrfs: Crossport btrfs_read_dev_super() from btrfs-progsQu Wenruo8-259/+378
This patch uses generic code from btrfs-progs to read one super block from block device. To support the btrfs-progs coding style, the following is also crossported: - BTRFS_SETGET_FUNC for btrfs_super_block - btrfs_check_super() function - Move btrfs_read_superblock() to disk-io.[ch] Since super.c only contains pretty small amount of code, and the extra check will be covered in later root read patches. Differences between this implementation and btrfs-progs: - No sbflags/sb_bytenr support Since we only need to read the primary super block (like kernel), sbflags/sb_bytenr used by super block recovery is not needed. This also changes the following behavior of U-Boot btrfs: - Only reads the primary super block The old implementation reads all 3 super blocks, and also one non-existing backup. This is not correct, especially if there is another filesystem created on the device but old superblocks are not rewritten. Just like kernel, we only check the primary super block.

2020-08-04fs/fat/fat.c: Do not perform zero block reads if there are no blocks leftJason Wessel1-1/+4
While using u-boot with qemu's virtio driver I stumbled across a problem reading files less than sector size. On the real hardware the block reader seems ok with reading zero blocks, and while we could fix the virtio host side of qemu to deal with a zero block read instead of crashing, the u-boot fat driver should not be doing zero block reads in the first place. If you ask hardware to read zero blocks you are just going to get zero data. There may also be other hardware that responds similarly to the virtio interface so this is worth fixing. Without the patch I get the following and have to restart qemu because it dies. --------------------------------- => fatls virtio 0:1 30 cmdline.txt => fatload virtio 0:1 ${loadaddr} cmdline.txt qemu-system-aarch64: virtio: zero sized buffers are not allowed --------------------------------- With the patch I get the expected results. --------------------------------- => fatls virtio 0:1 30 cmdline.txt => fatload virtio 0:1 ${loadaddr} cmdline.txt 30 bytes read in 11 ms (2 KiB/s) => md.b ${loadaddr} 0x1E 40080000: 64 77 63 5f 6f 74 67 2e 6c 70 6d 5f 65 6e 61 62 dwc_otg.lpm_enab 40080010: 6c 65 3d 30 20 72 6f 6f 74 77 61 69 74 0a le=0 rootwait. --------------------------------- Signed-off-by: Jason Wessel <jason.wessel@windriver.com> Signed-off-by: Jason Wessel <jason.wessel@windriver.com> Reviewed-by: Tom Rini <trini@konsulko.com>
