libsqfs: Initialize the return value in sqfs_compressor_create

2022-12-01T17:46:52+00:00

Initialize the output compressor pointer to NULL, so if the function fails, the value is propperly initialized to a NULL pointer instead of relying on the function user to initialize it. Signed-off-by: David Oberhollenzer

libsqfs: Fix an overzealous bounds check in the block processor

2022-12-01T17:46:52+00:00

When (during fragment deduplication) a fragment block is read back from disk and unpacked, it can happen that it is _exactly_ the given block size. The bounds check did '>=' instead of '>' and failed in that case with a "data corruption" error. Signed-off-by: David Oberhollenzer

Fix: documentation: directory header inode number signedness

2022-12-01T17:46:52+00:00

A directory listing starts with a header that specifies a reference inode number. Each entry then specifies a difference from that reference value. While the difference is _signed_, the reference value is _unsigned_. This is handled correctly in the code, but was pointent out wrongly in the documentation. Signed-off-by: David Oberhollenzer

Fix: libfstree: double free in error path

2022-08-19T16:54:24+00:00

If fstree_mknode fails, because the parent link count would overflow, the function fails and cleans up behind it. The problem arises because the function does this check *after* inserting the node in the parent node, so it is later free'd again, when destroying the rest of the tree. This patch moves the insertion after the check to mitigate the problem. Reported-by: Marvin Renich Signed-off-by: David Oberhollenzer

Fix: libfstree: actually use a full 32 bit hard link counter

2022-08-19T16:47:52+00:00

The squashfs on-disk format uses 32 bit link counters, but the fstree used 16 bit ones. Because the link count also includes child nodes, this artificially limited the number of entries in a directory to ~64k files. This patch removes the limit by switching libfstree to 32 bit counters.
