fs: btrfs: Prevent error pointer dereference in list_subvolums()

2023-08-08T21:05:43+00:00

If btrfs_read_fs_root() fails with -ENOENT, then we go to the next
entry.  Fine.  But if it fails for a different reason then we need
to clean up and return an error code.  In the current code it
doesn't clean up but instead dereferences "root" and crashes.

fs: btrfs: Introduce function to resolve path in one subvolume

2020-09-08T01:00:36+00:00

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.

fs: btrfs: Rename path resolve related functions to avoid name conflicts

2020-09-08T00:57:27+00:00

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.

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.

fs: btrfs: Sync btrfs_btree.h from kernel

2020-09-08T00:57:27+00:00

This version includes all needed on-disk format from kernel.

Only need to modify the include headers for U-Boot, everything else is
untouched.

Also, since U-Boot btrfs is using a different endian convert timing (at
tree block read time), it needs some forced type conversion before
proper crossport.
