fs/squashfs: sqfs_read: remove buggy offset functionality

2020-11-19T14:45:49Z

offset is the offset in the file read, not the offset in the destination buffer. If the offset is not null, this will lead to a memory corruption. So, for now, we are returning an error if the offset is used. Signed-off-by: Richard Genoud

fs/squashfs: sqfs_read: don't write beyond buffer size

2020-11-19T14:45:49Z

The length of the buffer wasn't taken into account when writing to the given buffer. Signed-off-by: Richard Genoud

fs/squashfs: sqfs_probe: use sqfs_decompressor_init() return value

2020-11-19T14:45:49Z

sqfs_decompressor_init() returns a value, so it's better to use it than to force the return value to EINVAL (it could be ENOMEM) Reviewed-by: Joao Marcos Costa Signed-off-by: Richard Genoud

fs/squashfs: sqfs_probe: reset cur_dev/cur_part_info to NULL on error

2020-11-19T14:45:49Z

Resetting the context on error will prevent some checks like: if (!ctx.cur_dev) To pass when the probe method has failed Signed-off-by: Richard Genoud

fs/squashfs: sqfs_read: fix memory leak on finfo.blk_sizes

2020-11-19T14:45:49Z

finfo.blk_sizes may not be freed in case of error in the for loop Setting it to null and freeing it at the end makes prevents that from happening. Reviewed-by: Joao Marcos Costa Signed-off-by: Richard Genoud

fs/squashfs: sqfs_get_abs_path: fix possible memory leak on error

2020-11-19T14:45:49Z

2020-11-19T14:45:49Z

the return value of sqfs_tokenize(rel_tokens, rc, rel); wasn't checked. (but "ret" value was !) This is obviouly a typo. Reviewed-by: Joao Marcos Costa Signed-off-by: Richard Genoud
