f337fb9ea8 fs: Quieten down the filesystems more
When looking for a filesystem on a partition we should do so quietly. At
present if the filesystem is very small (e.g. 512 bytes) we get a host of
messages.

Update these to only show when debugging.

a51eb8de31 blk: Use a function for whether block devices are available
At present we use HAVE_BLOCK_DEVICE to indicate when block devices are
available.

This is a very strange option, since it partially duplicates the BLK
option used by driver model. It also covers both U-Boot proper and SPL,
even though one might have block devices and another not.

As a first step towards correcting this, create a new inline function
called blk_enabled() which indicates if block devices are available.
This cannot be used in Makefiles, or #if clauses, but can be used in C
code.

A function is useful because we cannot use CONFIG_IS_ENABLED(BLK) to
decide if block devices are needed, since we must consider the legacy
block interface, enabled by HAVE_BLOCK_DEVICE

Update a few places where it can be used and drop some unnecessary #if
checks around some functions in disk/part.c - rely on the compiler's
dead-code elimination instead.

661cdaa79d cyclic: Integrate cyclic infrastructure into WATCHDOG_RESET
This patch integrates the main function responsible for calling all
registered cyclic functions cyclic_run() into the common WATCHDOG_RESET
macro. This guarantees that cyclic_run() is executed very often, which
is necessary for the cyclic functions to get scheduled and executed at
their configured periods.

If CONFIG_WATCHDOG is not enabled, only cyclic_run() without calling
watchdog_reset(). This guarantees that the cyclic functionality does not
rely on CONFIG_WATCHDOG being enabled.

A large number of files include <flash.h> as it used to be how various
SPI flash related functions were found, or for other reasons entirely.
In order to migrate some further CONFIG symbols to Kconfig we need to
not include flash.h in cases where we don't have a NOR flash of some
sort enabled.  Furthermore, in cases where we are in common code and it
doesn't make sense to try and further refactor the code itself in to new
files we need to guard this inclusion.

69ca709d0f ubifs: Fix reference count leak in ubifsumount
Original ubifs code was designed that after ubifs_umount() call it is
required to also call ubi_close_volume() which closes underlying UBI
volume. But U-Boot ubifs modification have not implemented it properly
which caused that ubifsumount command contains resource leak. It can be
observed by calling simple sequence of commands:

  => ubi part mtd2
  ubi0: attaching mtd2
  ...
  => ubifsmount ubi0
  => ubifsumount
  Unmounting UBIFS volume rootfs!
  => ubi detach
  ubi0 error: ubi_detach_mtd_dev: ubi0 reference count 1, destroy anyway
  ubi0: detaching mtd2
  ubi0: mtd2 is detached

Fix this issue by calling ubi_close_volume() and mutex_unlock() in
directly in ubifs_umount() function before freeing U-Boot's global
ubifs_sb. And remove duplicate calls of these two functions in remaining
places. Note that when ubifs_umount() is not called then during error
handling is still needed to call ubi_close_volume() and mutex_unlock.

With this change ubifsumount command does not throw that error anymore:

  => ubi part rootfs
  ubi0: attaching mtd2
  ...
  => ubifsmount ubi0
  => ubifsumount
  Unmounting UBIFS volume rootfs!
  => ubi detach
  ubi0: detaching mtd2
  ubi0: mtd2 is detached

7f7fb9937c fs/squashfs: Use kcalloc when relevant
A crafted squashfs image could embed a huge number of empty metadata
blocks in order to make the amount of malloc()'d memory overflow and be
much smaller than expected. Because of this flaw, any random code
positioned at the right location in the squashfs image could be memcpy'd
from the squashfs structures into U-Boot code location while trying to
access the rearmost blocks, before being executed.

In order to prevent this vulnerability from being exploited in eg. a
secure boot environment, let's add a check over the amount of data
that is going to be allocated. Such a check could look like:

if (!elem_size || n > SIZE_MAX / elem_size)
	return NULL;

The right way to do it would be to enhance the calloc() implementation
but this is quite an impacting change for such a small fix. Another
solution would be to add the check before the malloc call in the
squashfs implementation, but this does not look right. So for now, let's
use the kcalloc() compatibility function from Linux, which has this
check.

2ac0baab4a fs/squashfs: sqfs_read: Prevent arbitrary code execution
Following Jincheng's report, an out-of-band write leading to arbitrary
code execution is possible because on one side the squashfs logic
accepts directory names up to 65535 bytes (u16), while U-Boot fs logic
accepts directory names up to 255 bytes long.

Prevent such an exploit from happening by capping directory name sizes
to 255. Use a define for this purpose so that developers can link the
limitation to its source and eventually kill it some day by dynamically
allocating this array (if ever desired).

339f652992 ubifs: Fix lockup/crash when reading files
Commit b1a14f8a1c ("UBIFS: Change ubifsload to not read beyond the
requested size") added optimization to do not read more bytes than it is
really needed. But this commit introduced incorrect handling of the hole at
the end of file. This logic cause U-Boot to crash or lockup when trying to
read from the ubifs filesystem.

When read_block() call returns -ENOENT error (not an error, but the hole)
then dn-> structure is not filled and contain garbage. So using of dn->size
for memcpy() argument cause that U-Boot tries to copy unspecified amount of
bytes from possible unmapped memory. Which randomly cause lockup of P2020
CPU.

Fix this issue by copying UBIFS_BLOCK_SIZE bytes from read buffer when
dn->size is not available. UBIFS_BLOCK_SIZE is the size of the buffer
itself and read_block() fills buffer by zeros when it returns -ENOENT.

This patch fixes ubifsload on P2020.

7c075433fe fs/btrfs: fix a bug that U-boot fs btrfs implementation doesn't handle NO_HOLE feature correctly
[BUG]
When passing a btrfs with NO_HOLE feature to U-boot, and if one file
contains holes, then the hash of the file is not correct in U-boot:

 # mkfs.btrfs -f test.img	# Since v5.15, mkfs defaults to NO_HOLES
 # mount test.img /mnt/btrfs
 # xfs_io -f -c "pwrite 0 4k" -c "pwrite 8k 4k" /mnt/btrfs/file
 # md5sum /mnt/btrfs/file
 277f3840b275c74d01e979ea9d75ac19  /mnt/btrfs/file
 # umount /mnt/btrfs
 # ./u-boot
 => host bind 0 /home/adam/test.img
 => ls host 0
 <   >      12288  Mon Dec 27 05:35:23 2021  file
 => load host 0 0x1000000 file
 12288 bytes read in 0 ms
 => md5sum 0x1000000 0x3000
 md5 for 01000000 ... 01002fff ==> 855ffdbe4d0ccc5acab92e1b5330e4c1

The md5sum doesn't match at all.

[CAUSE]
In U-boot btrfs implementation, the function btrfs_read_file() has the
following iteration for file extent iteration:

	/* Read the aligned part */
	while (cur < aligned_end) {
		ret = lookup_data_extent(root, &path, ino, cur, &next_offset);
		if (ret < 0)
			goto out;
		if (ret > 0) {
			/* No next, direct exit */
			if (!next_offset) {
				ret = 0;
				goto out;
			}
		}
		/* Read file extent */

But for NO_HOLES features, hole extents will not have any extent item
for it.
Thus if @cur is at a hole, lookup_data_extent() will just return >0, and
update @next_offset.

But we still believe there is some data to read for @cur for ret > 0
case, causing we read extent data from the next file extent.

This means, what we do for above NO_HOLES btrfs is:
- Read 4K data from disk to file offset [0, 4K)
  So far the data is still correct

- Read 4K data from disk to file offset [4K, 8K)
  We didn't skip the 4K hole, but read the data at file offset [8K, 12K)
  into file offset [4K, 8K).

  This causes the checksum mismatch.

[FIX]
Add extra check to skip to the next non-hole range after
lookup_data_extent().

2ad74301a0 fs: yaffs2: Finish Kconfig migration
For the symbols which are both hard-coded as enabled and used, move to
Kconfig.  The rest of the CONFIG_YAFFS namespace is unselected anywhere,
so we leave it as is.

0d1ecc99cb mtd: Remove mtd_erase_callback() entirely
The original purpose of mtd_erase_callback() in Linux at the time it was
imported to U-Boot, was to inform the caller that erasing is done (since
it was an asynchronous operation).

All supplied callback methods in U-Boot do nothing, but the
mtd_erase_callback() function was (until previous patch) grossly abused
in U-Boot's mtdpart implementation for completely different purpose.

Since we got rid of the abusement, remove the mtd_erase_callback()
function and the .callback member from struct erase_info entirely, in
order to avoid such problems in the future.

41130eb893 fs: fat: check for buffer size before reading blocks
This patch optimizes the commit mentioned below by avoiding running
a set of commands which are useless in the case when
size < mydata->sect_size and sect_count would be 0.

Fixes: 5b3ddb17ba ("fs/fat/fat.c: Do not perform zero block reads if there are no blocks left")
