- Bring in the update to btrfs support that rewrites it based on btrfs-progs.
-
Since the current code base is mostly from btrfs-progs, anyone contributing to U-Boot btrfs code could also help us to improve btrfs-progs and btrfs kernel module. Also add myself as designated reviewer. Signed-off-by:

This patch introduces a new function, get_path_in_subvolume(), which resolves inode number into path inside a subvolume. This function will be later used for btrfs subvolume list functionality. Signed-off-by:

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. Signed-off-by:

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. Signed-off-by:
-
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. Signed-off-by:
-
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. Signed-off-by:
-
The existing __btrfs_readlink() can be easily re-implemented using the extent buffer based btrfs_readlink(). This is the first step to re-implement U-Boot's btrfs code. Signed-off-by:
-
Since the old code is using __btrfs_path/__btrfs_root which is different from the regular extent buffer based one, we add "__" prefix for the old implementation to avoid name conflicts for the incoming crossport. Signed-off-by:

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. Signed-off-by:
-
These two functions play a big role in btrfs bootstrap. The following function is removed: - Seed device support Although in theory we can still support multiple devices, we don't have a facility in U-Boot to do device scan without opening them. Signed-off-by:
-
This patch copies the core function, btrfs_search_slot(), from btrfs-progs. 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. Remove it completely. With the core function in place, btrfs developers should feel at home now. This also crossports supporting code like btrfs_previous_item() to ctree.[ch]. Signed-off-by:
-
Crossport struct btrfs_root to ctree.h from btrfs-progs, with write related members deleted. Signed-off-by:

This is to avoid naming conflicts between extent buffer based btrfs_root. Signed-off-by:
-
To avoid name conflicting between the extent buffer based btrfs_path from btrfs-progs, rename struct btrfs_path to struct __btrfs_path. Also rename btrfs_free_path() to __btrfs_free_path() to avoid conflicts. Signed-off-by:

This is the one of the basic stone function for btrfs, which: - Resolves the chunk mappings - Reads data from disk - Does various sanity check With read_tree_block(), we can finally crossport needed btrfs btree operations to U-Boot. Signed-off-by:
-
This patch crossports volumes.[ch] from btrfs-progs, including: - btrfs_map_block() The core mechanism to map btrfs logical address to physical address. This version includes multi-device support, along with RAID56 support. - btrfs_scan_one_device() This is the function to register one btrfs device to the list. This is the main part of the multi-device btrfs assembling process. Although we're not going to support multiple devices until U-Boot allows us to scan one device without actually opening it.

This brings all structure accessors from btrfs-progs/ctree.h, as in kernel's ctree.h. All these accessors handle the endian convert at runtime, and since all of them are defined as static inline functions, those which aren't used won't take space in resulting binary. Signed-off-by:

This brings the extent_io_tree infrastructure, with which we can finally bring in proper btrfs_fs_info structure to ctree.h. With read/write_extent_buffer() implemented we also backport read/write_eb_member() to ctree.h. Signed-off-by:

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. Signed-off-by:

This mostly crossports crypto/hash.[ch] from btrfs-progs. The differences are: - No blake2 support No blake2 related library in U-Boot yet. - Use uboot xxhash/sha256 directly No need to implement the code as U-Boot has already provided the interface. This adds the support for the following csums: - SHA256 - XXHASH Signed-off-by:
