fs: exfat: Inhibit unused exfat_humanize_bytes() and exfat_print_info()

2025-05-05T20:19:20Z

Make sure unused exfat_humanize_bytes() and exfat_print_info() functions are not compiled into U-Boot code base. This also removes CID 550300: Integer handling issues (INTEGER_OVERFLOW) in exfat_humanize_bytes() , which is now surely unreachable. Signed-off-by: Marek Vasut

fs: exfat: Use strncpy() and bail on too long filenames

2025-05-05T20:19:20Z

In case the filename is too long, longer than PATH_MAX - 1, it would overflow dirs->dirname array. Add missing check and also use strncpy() to prevent the overflow in any case. Fixes CID 550305: Security best practices violations (STRING_OVERFLOW) Signed-off-by: Marek Vasut

fs/squashfs: avoid illegal free() in sqfs_opendir()

2025-04-21T17:08:03Z

* Use calloc() to allocate token_list. This avoids an illegal free if sqfs_tokenize() fails. * Do not iterate over token_list if it has not been allocated.

fs: exfat: Implement trivial 'rename' support

2025-04-21T17:07:04Z

Implement exfat_fs_rename() to rename or move files. This is used by the 'mv' generic FS interface command. The rename implementation for other filesystems was added recently and was not part of exfat porting layer due to merge issue, which made 'mv' command crash, fix this by adding the missing implementation.

fs: exfat: Fix exfat_fs_exists() return value

2025-04-21T17:07:04Z

The exfat_fs_exists() should return 0 in case the path does not exist, and 1 in case the path does exist. Fix the inverted return value. This fixes 'test -e' command with exfat. Fixes: b86a651b646c ("fs: exfat: Add U-Boot porting layer") Signed-off-by: Marek Vasut

fs: exfat: Rework exfat_fs_readdir() to behave like exfat_fs_ls()

2025-04-21T17:07:04Z

The exfat_fs_readdir() depends on state created in exfat_fs_opendir(), but that state may be disrupted by fs_close() called by the FS layer in fs_opendir(), because exfat porting layer unmounts the filesystem in ->close() callback. To avoid this disruption, avoid creating state in exfat_fs_opendir(), cache only the directory name to list there, and rework exfat_fs_readdir() to work in a similar way to exfat_fs_ls(). That is, make exfat_fs_readdir() open the directory, look up specific entry, extract its properties to be reported to FS layer, and close the directory. This is slow, but avoids the disruption. The slowness does not affect regular 'ls' command, which uses exfat_fs_ls() fast path. Fixes: b86a651b646c ("fs: exfat: Add U-Boot porting layer") Signed-off-by: Marek Vasut

fs: exfat: Inhibit "impossible" print on write to bogus file

2025-04-21T17:07:04Z

Write into a bogus file, like '/.', triggers an "impossible" print from the exfat core code. That should not be printed in U-Boot, because U-Boot prints its own error message sooner. Inhibit this error message. The following command triggers the bogus print: " => save host 0:0 1000008 /. 0x10 " Fixes: b86a651b646c ("fs: exfat: Add U-Boot porting layer") Signed-off-by: Marek Vasut

fs: exfat: Flush node before put in read() callback

2025-04-21T17:07:04Z

Make sure the node is never dirty before being released, flush the node first using exfat_flush_node() and only then release the node using exfat_put_node(). This now matches the behavior of exfat_fs_write() too. Fixes: b86a651b646c ("fs: exfat: Add U-Boot porting layer") Signed-off-by: Marek Vasut

Merge patch series "Switch to using $(PHASE_) in Makefiles"

2025-04-11T18:16:49Z

Tom Rini says: This series switches to always using $(PHASE_) in Makefiles when building rather than $(PHASE_) or $(XPL_). It also starts on documenting this part of the build, but as a follow-up we need to rename doc/develop/spl.rst and expand on explaining things a bit.

Kbuild: Always use $(PHASE_)

2025-04-11T18:16:44Z

It is confusing to have both "$(PHASE_)" and "$(XPL_)" be used in our Makefiles as part of the macros to determine when to do something in our Makefiles based on what phase of the build we are in. For consistency, bring this down to a single macro and use "$(PHASE_)" only. Signed-off-by: Tom Rini
