For a squashfs filesystem, the fragment table is followed by
the following tables: NFS export table, ID table, xattr table.
The export and xattr tables are both completely optional, but
the ID table is mandatory. The Linux implementation refuses to
mount the image if the ID table is missing. Tables that are no
present have their location in the super block set
to 0xFFFFFFFFFFFFFFFF.
The u-boot implementation previously assumed that it can always
rely on the export table location as an upper bound for the fragment
table, trying (and failing) to read past filesystem bounds if it
is not present.
This patch changes the driver to use the ID table instead and only
use the export table location if it lies between the two.

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

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

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.

Prevent such an exploit from happening by capping directory name sizes

limitation to its source and eventually kill it some day by dynamically

When read_block() call returns -ENOENT error (not an error, but the hole)

[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

12288 bytes read in 0 ms

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().

BTRFS volume consists of a number of subvolumes which can be mounted separately
from each other. The top-level subvolume always exists even if no subvolumes
were created manually. A subvolume can be denoted as the default subvolume i.e.
the subvolume which is mounted by default.
The default "default subvolume" is the top-level one, but this is far from the
common practices used in the wild. For instance, openSUSE provides an OS
snapshot/rollback feature based on BTRFS. To achieve this, the actual OS root
filesystem is located into a separate subvolume which is "default" but not
"top-level". That means that the /boot/dtb/ directory is also located inside
this default subvolume instead of top-level one.
However, the existing btrfs u-boot driver always uses the top-level subvolume
as the filesystem root. This behaviour 1) is inconsistent with
mount /dev/sda1 /target
command, which mount the default subvolume 2) leads to the issues when
/boot/dtb cannot be found properly (see the reference).
This patch uses the default subvolume as the filesystem root to overcome
mentioned issues.

In SquashFS, the contents of a directory is stored by
squashfs_directory_entry structures which contain the file's name, inode
and position within the filesystem.
The inode number is not stored directly; instead each directory has one
or more headers which set a base inode number, and files store the
offset from that to the file's inode number.
In mksquashfs, each inode is allocated a number in the same order as
they are written to the directory table; thus the offset from the
header's base inode number to the file's inode number is usually
positive.
Hardlinks are simply stored with two directory entries referencing the
same file. This means the second entry will thus have an inode number
much lower than the surrounding files. Since the header's base inode
number comes from the first entry that uses the header, this delta will
usually be negative.
Previously, U-Boot's squashfs_directory_entry.inode_offset field was
declared as an unsigned value. Thus when a negative value was found, it
would either resolve to an invalid inode number or to that of an
unrelated file.
A squashfs image to test this can be created like so:
echo hi > sqfs_test_files/001-root-file
mkdir sqfs_test_files/002-subdir
touch sqfs_test_files/002-subdir/003-file
ln sqfs_test_files/{001-root-file,002-subdir/004-link}
mksquashfs sqfs_test_files/ test.sqfs -noappend
Note that squashfs sorts the files ASCIIbetacally, so we can use the
names to control the order they appear in. The ordering is important -
the first reference to the file must have a lower inode number than the
directory in which the second reference resides, and the second
reference cannot be the first file in the directory.
Listing this sample image in U-Boot results in:
=> sqfsls virtio 2 002-subdir
0 003-file
Inode not found.

The fragmented files were not correctly read because of two issues:
- The squashfs_file_info struct has a field named 'comp', which tells if
the file's fragment is compressed or not. This field was always set to
'true' in sqfs_get_regfile_info and sqfs_get_lregfile_info. It should
actually take sqfs_frag_lookup's return value. This patch addresses
these two assignments.
- In sqfs_read, the fragments (compressed or not) were copied to the
output buffer through a for loop which was reading data at the wrong
offset. Replace these loops by equivalent calls to memcpy, with the
right parameters.

When reading directories the UEFI sub-system must supply file attributes
and timestamps. These fields will have to be added to struct fs_dirent.
SquashFS should not fill these fields with random data. Ensure that they
are zeroed out.

There are some cases where decompressed sectors can have padding zeros.
In kernel code, we have lines to address such situation:
/*
* btrfs_getblock is doing a zero on the tail of the page too,
* but this will cover anything missing from the decompressed
* data.
*/
if (bytes < destlen)
memset(kaddr+bytes, 0, destlen-bytes);
kunmap_local(kaddr);
But not in U-boot code, thus we have some reports of U-boot failed to
read compressed files in btrfs.
Fix it by doing the same thing of the kernel, for both inline and
regular compressed extents.

The function jffs2_1pass_read_inode() was discarding the summary
inodes and dirent because the value in datacrc flag wasn't
initialized in function jffs2_sum_process_sum_data().
This fix initializes the status of all summary records to indicate
that the CRC needs to be verified when they are loaded.
Before this fix, the behaviors produced by the undefined value of
datacrc was:
- Summary's registries were discarded when 'b->datacrc' is equal
as 'CRC_BAD'.
- Summary's registries were not checked when b->datacrc differs of
'CRC_BAD' and 'CRC_UNKNOWN'
So, almost all of the time the crc just isn't checked, and in some
cases the registries are discarded.

When the btrfs_read_fs_root() function is searching a ROOT_ITEM with
location key offset other than -1, it currently fails via BUG_ON.
The offset can have other value than -1, though. This can happen for
example if a subvolume is renamed:
$ btrfs subvolume create X && sync
Create subvolume './X'
$ btrfs inspect-internal dump-tree /dev/root | grep -B 2 'name: X$
location key (270 ROOT_ITEM 18446744073709551615) type DIR
transid 283 data_len 0 name_len 1
name: X
$ mv X Y && sync
$ btrfs inspect-internal dump-tree /dev/root | grep -B 2 'name: Y$
location key (270 ROOT_ITEM 0) type DIR
transid 285 data_len 0 name_len 1
name: Y
As can be seen the offset changed from -1ULL to 0.
Do not fail in this case.

This patch involves no functional change. It is just about code
readability.
Both in file_fat_write_at() and fat_mkdir() the incoming file or directory
path are split into two parts: the parent directory and the base name.
In file_fat_write_at() the value of the variable basename is assigned to
the filename parameter and afterwards the variable filename is used instead
of basename. It is more readable to use the variable basename and leave
filename unchanged.
In fat_mkdir() the base name variable is called directory. This is
confusing. Call it basename like in file_fat_write_at(). This allows to
rename parameter new_directory to directory in the implementation of
fat_mkdir() to match the function declaration.
