fs/squashfs: sqfs_read: Prevent arbitrary code execution

2022-06-16T19:22:55+00:00

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).

fs: Add a function to set the filesystem type

2022-04-25T14:00:03+00:00

When sandbox is used with hostfs we won't have a block device, but still
must set up the filesystem type before any filesystem operation, such as
loading a file. Add a function to handle this.

fs: Add semihosting filesystem

2022-04-01T19:03:13+00:00

This adds a filesystem which is backed by the host's filesystem. It is
modeled off of sandboxfs, which has very similar aims. Semihosting
doesn't support listing directories (except with SYS_SYSTEM), so neither
do we. it's possible to optimize a bit for the common case of reading a
whole file by omitting a call to smh_seek, but this is left as a future
optimization.

doc: replace @return by Return:

2022-01-19T17:11:34+00:00

Sphinx expects Return: and not @return to indicate a return value.

find . -name '*.c' -exec \
sed -i 's/^\(\s\)\*\(\s*\)@return\(\s\)/\1*\2Return:\3/' {} \;

find . -name '*.h' -exec \
sed -i 's/^\(\s\)\*\(\s*\)@return\(\s\)/\1*\2Return:\3/' {} \;

When reading a directory in the UEFI file system we have to return file
attributes and timestamps. Copy this data to the directory entry structure.

compression but support for zlib will be added in a follow-up commit.

command: Remove the cmd_tbl_t typedef

2020-05-18T22:36:55+00:00

We should not use typedefs in U-Boot. They cannot be used as forward
declarations which means that header files must include the full header to
access them.

Drop the typedef and rename the struct to remove the _s suffix which is
now not useful.

This requires quite a few header-file additions.
