fs: btrfs: Do not free multi when guaranteed to be NULL

2025-07-15T15:55:37+00:00

multi is guaranteed to be NULL in the first two error exit paths so the
attempt to free it is not needed. Remove those calls.

fs: btrfs: hide duplicate 'Cannot lookup file' error on 'load'

2024-11-15T19:11:47+00:00

Running commands such as 'load mmc 2:1 $addr $path' when path does not
exists will print an error twice if the file does not exist, e.g.:
```
Cannot lookup file boot/boot.scr
Failed to load 'boot/boot.scr'
```
(where the first line is printed by btrfs and the second by common fs
code)

Historically other filesystems such as ext4 or fat have not been
printing a message here, so do the same here to avoid duplicate.

The other error messages in this function are also somewhat redundant,
but bring useful diagnostics if they happen somewhere, so have been left
as printf.

Note that if a user wants no message to be printed for optional file
loads, they have to check for file existence first with other commands
such as 'size'.

fs: btrfs: fix out of bounds write

2024-06-26T15:55:53+00:00

Fix btrfs_read/read_and_truncate_page write out of bounds of destination
buffer. Old behavior break bootstd malloc'd buffers of exact file size.
Previously this OOB write have not been noticed because distroboot usually
read files into huge static memory areas.

Revert "Merge patch series "arm: dts: am62-beagleplay: Fix Beagleplay Ethernet""

2024-05-19T14:16:36+00:00

When bringing in the series 'arm: dts: am62-beagleplay: Fix Beagleplay
Ethernet"' I failed to notice that b4 noticed it was based on next and
so took that as the base commit and merged that part of next to master.

This reverts commit c8ffd1356d42223cbb8c86280a083cc3c93e6426, reversing
changes made to 2ee6f3a5f7550de3599faef9704e166e5dcace35.

fs: btrfs: fix reading when length specified

2023-11-16T23:59:58+00:00

The btrfs read function limits the read length to ensure that it
and the read offset do not together exceed the size of the file.
However, this size was only being queried if the read length was
passed a value of zero (meaning "whole file"), and the size is
defaulted to 0 otherwise. This means the clamp will just zero out
the length if one is specified, preventing reading of the file.

Fix this by checking the file size unconditionally, and unifying
the default length and clamping logic as a single range check instead.

This bug was discovered when trying to boot Linux with initrd= via
'bootefi' from a btrfs partition. The EFI stub entered an infinite
loop of zero-length reads while trying to read the initrd, and the
boot process stalled indefinitely.
