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.

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

Cleanup: split libsquashfs xattr writer code

2020-06-09T04:04:08+00:00

This commit moves the libsquashfs xattr related code into a sub directory and splits the xattr writer code up into several files. No actual code is changed. Signed-off-by: David Oberhollenzer
