fs/squashfs: Fix compilation error

2021-03-04T19:40:52+00:00

Commit 401d1c4f5d2d29c4bc4beaec95402ca23eb63295 ("common: Drop
asm/global_data.h from common header") broke compilation of squashfs
filesystem when CONFIG_CMD_SQUASHFS=y is enabled.

Compilation is failing on error:

    aarch64-linux-gnu-ld.bfd: u-boot/fs/squashfs/sqfs_inode.c:121: undefined reference to `le32_to_cpu'

fs: btrfs: do not fail when offset of a ROOT_ITEM is not -1

2021-03-01T14:53:46+00:00

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.

fs: btrfs: change directory list output to be aligned as before

2021-02-24T21:51:48+00:00

Since commit 325dd1f642dd ("fs: btrfs: Use btrfs_iter_dir() to ...")
when btrfs is listing a directory, the output is not aligned:

           15  Wed Sep 09 13:20:03 2020  boot.scr -> @/boot/boot.scr
            0  Tue Feb 02 12:42:09 2021  @
          108  Tue Feb 02 12:54:04 2021  1.info

Return back to how it was displayed previously, i.e.:

           15  Wed Sep 09 13:20:03 2020  boot.scr -> @/boot/boot.scr
            0  Tue Feb 02 12:42:09 2021  @
  <   >        108  Tue Feb 02 12:54:04 2021  1.info

Instead of '', print '<   >', as ext4 driver.

If an unknown directory item type is encountered, we will print the type
number left padded with spaces, enclosed by '?', instead of '<' and '>',
i.e.:

  ? 30?        .............................  name

sqfs_opendir() called in sqfs_size(), sqfs_read(), sqfs_exists() may fail
leading to sqfs_closedir(NULL) being called. Do not dereference NULL.

Directories or files called '.' or '..' cannot be created or written to
in any directory. Move the test to normalize_longname() to check this

fs: fat: usage basename in file_fat_write_at, fat_mkdir

2021-02-03T08:52:51+00:00

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.

common: Drop asm/global_data.h from common header

2021-02-02T20:33:42+00:00

Move this out of the common header and include it only where needed.  In
a number of cases this requires adding "struct udevice;" to avoid adding
another large header or in other cases replacing / adding missing header
files that had been pulled in, very indirectly.   Finally, we have a few
cases where we did not need to include  at all, so
remove that include.
