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: remove dead code

2026-05-18T07:19:56Z

This code is dead because it appears after an infinite loop; remove it. Fixes: d5888d509cc4 ("fs: ubifs: fix bugs involving symlinks in ubifs_findfile") Signed-off-by: Peter Collingbourne Reviewed-by: Heiko Schocher hs: corrected the commit ID

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.

fat: initialize ret in disk_rw()

2026-05-04T20:35:10Z

If fat_sect_size = 0 and nr_sect = 0, the value of ret is never initialized. A random return value is returned. Initialize ret to 0. Addresses-Coverity-ID: - 645495 Uninitialized scalar variable Signed-off-by: Heinrich Schuchardt Reviewed-by: Simon Glass

fs/squashfs: Set ret to 0 on successful read

2026-04-24T17:28:10Z

It might still be a positive number due to the call to sqfs_disk_read. This only happens when reading a file from an uncompressed squashfs. I found this by trying to boot using the extlinux bootmethod, where positive values are treated as errors. Signed-off-by: Michael Zimmermann Acked-by: Richard Genoud Reviewed-by: Simon Glass

fs: fat: Refactor dirty flag handling

2026-03-27T19:14:18Z

Refactor the dirty flag handling a little bit so an inline function is called instead of directly stuffing a value into the variable. This allows variable that holds the flag to be completely removed if its not used i.e. CONFIG_FAT_WIRTE=n Signed-off-by: Daniel Palmer

Merge patch series "Introduce SQUASHFS support in SPL"

2026-03-26T17:04:41Z

Richard Genoud says: SquashFS has support in U-Boot, but not in SPL. This series adds the possibility for the SPL to load files from SquashFS partitions. This is useful, for instance, when there's a SquashFS rootfs containing U-Boot binary. NB: falcon mode is not supported yet.

spl: add squashfs support

2026-03-26T17:04:28Z

Implement spl_load_image_sqfs() in spl code. This will be used in MMC to read a file from a squashfs partition. Also, loosen squashfs read checks on file size by not failing when a bigger size than the actual file size is requested. (Just read the file) This is needed for FIT loading, because the length is ALIGNed. Signed-off-by: Richard Genoud Reviewed-by: Miquel Raynal Reviewed-by: João Marcos Costa
