Merge patch series "fs: btrfs: add support for readdir"

2026-07-10T21:55:23Z

Alexey Charkov says: Btrfs in U-boot currently uses a custom callback for ls and doesn't expose the standard opendir/readdir/closedir interface, making it harder to use in generic code. One area where this would be useful is in discovering BLS type 1 entries [1] on a Btrfs filesystem. Add support for the standard interface, and implement ls in terms of it.

fs: btrfs: use fs_ls_generic() and drop custom implementation

2026-07-10T21:55:01Z

Now that generic callbacks for opendir/readdir/closedir are implemented, the custom btrfs_ls() implementation is no longer needed, along with the btrfs_iter_dir() callback iterator. Use fs_ls_generic() instead. Signed-off-by: Alexey Charkov Reviewed-by: Qu Wenruo

fs: ubifs: fix ubifs_finddir() result check

2026-07-08T09:28:23Z

ubifs_finddir() can return a negative error code (-ENOMEM or PTR_ERR(dent)) and returns 1 when the name is found in the directory. Fix the result check accordingly. This fixes file existence detection (for "test -e") when U-Boot uses UBIFS through ops ubifs_exists(). Since this function is also called before other file operations, commands such as "load" could be executed on a non-existing file without reporting an error.

fs: fat: fix seconds in timestamp

2026-05-27T23:59:12Z

The FAT time format stores seconds/2 in bits 4:0. The expression 'tm.tm_sec > 1' is a boolean comparison (yields 0 or 1) where a right-shift 'tm.tm_sec >> 1' was intended. As a result every file timestamp written by U-Boot has its seconds field set to either 0 or 1, depending on whether tm_sec is greater than 1. Also fix the indentation of the tm_hour line.

fs: ubifs: fix bugs involving symlinks in ubifs_findfile

2026-05-11T18:18:56Z

When encountering a symlink pointing to an absolute path, ubifs_findfile would return the target of the symlink as the result instead of resolving any following components in the original path. Fix it by following the same code path that is used for relative paths except that we set the next inode to the root if we see a leading slash. The existing code used memcpy and sprintf to copy the symlink target into a fixed size stack buffer and was therefore vulnerable to buffer overflows with a sufficiently long symlink target. Fix it by using a heap buffer for the temporary path during path resolution.
