Implement rudimentary reference counting for sqfs_object_t

2023-01-19T15:24:56+00:00

Implement grab/drop functions to increase/decrease reference count and destroy the object if the count drops to 0. Make sure that all objects that maintain internal references actually grab that reference, duplicate it in the copy function, drop it in the destroy handler. Signed-off-by: David Oberhollenzer

Add a helper function to initialize libsquashfs objects

Cleanup: move libutil headers to sub directory

2022-07-08T17:17:35+00:00

Move all the libutil stuff from the toplevel include/ to a util/ sub directory and fix up the includes that make use of them. Signed-off-by: David Oberhollenzer

Store xattr writer block description in a red-black tree

2021-03-06T21:08:36+00:00

By storing the blocks in a tree, the de-duplication can lookup existing blocks in logartihmic instead of linear time. The linked list is still maintained, because we need to iterate over the blocks in creation order during serialization. Signed-off-by: David Oberhollenzer

Fix: libsquashfs: xattr_writer: return NULL if calloc fails

2020-11-07T16:06:33+00:00

Instead of dereferencing the NULL pointer and crashing. Signed-off-by: David Oberhollenzer

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.
