Fix: xattr reader: read the header after seaking to an OOL value

2020-07-29T11:31:08+00:00

If an xattr value is stored OOL, the value actually holds an 8 byte reference to another, previously stored value. This reference points to the header that we need to read to know the actual size of the value before reading it, not the value itself, so after reading the reference and seeking to it, the xattr reader needs to read the actual header.

Fix block bounds checking in libsquashfs data reader

2020-06-20T17:18:32+00:00

Instead of doing the fragile size comparison in both loops, simply bail from the function if offset is out of bounds, clamp the size to the available range of the file and abail if it is zero. As a result, a lot of checks can be removed and the function will not return data beyond EOF. This problem occoured with files that have a short last block instead of a fragment.

Cleanup: mark sqfs_xattr_writer_flush writer argument as const

2020-06-09T04:51:31+00:00

It does not make any changes to the writer itself, so mark it as const. This also requires some similar changes to the string table. Signed-off-by: David Oberhollenzer

Cleanup: remove refcount adjusting in sqfs_xattr_writer_end

2020-06-09T04:36:32+00:00

After finding a match, reducing the reference count of the matched elements and increasing them afterwards leaves the reference count identical, because they refere to the same entries. Signed-off-by: David Oberhollenzer
