Add hard link support to gensquashfs and tar2sqfs

2019-12-22T21:07:44+00:00

In libtar, set a special flag if the header is actually a hard link. In tar2sqfs, create a hard link node and skip the rest for hard links. Also refues to set the root attributes from a hard link, it may refere to a node that we have missed earlier, there is nothing else that we can do here. In fstree_from_file, add a "link" command for adding hard links. Signed-off-by: David Oberhollenzer

Add basic support for handling and serializing hard links

2019-12-22T21:07:44+00:00

In libfstree, add a function to add a hard link to the fstree. The hard links stores the target in the data.target field, canonicalizes the target and sets a sentinel mode. A second function is used to resolve link, i.e. replacing it with a direct pointer, setting another sentinel mode and increasing the targets link count. The post process function tries to resolve unresolved hard links and only allocates inode numbers for nodes that aren't hard links. If the target node of a hard link does not have an inode number yet, the two need to be swapped, since this is also the order in which they are serialized. The serialization function in libcommon simply has to skip hard link nodes and when writing directory entries, use the inode num/ref of the target node. Signed-off-by: David Oberhollenzer

Cleanup: merge the fstree post processing functions

2019-12-18T14:55:03+00:00

Instead of having 3 different functions for sorting the tree, numbering the nodes and generating a file list, that all have to be used in the right order, this commit merges them into a single "fstree_post_process" function. Signed-off-by: David Oberhollenzer

Cleanup: Return combined return value from compressor id by name

2019-11-28T15:11:22+00:00

Instead of returning the ID through a pointer and an error code as return status, return a single int that could be a compressor ID (positive values) or an error code (negative values). Signed-off-by: David Oberhollenzer

Cleanup: move overflow safe alloc code into libsquashfs

2019-11-25T12:20:08+00:00

There were only a hand full of instances outside libsquashfs that used the alloc code. In most cases, the thing allocated hat its size derived from something already in memory anyway, so it is safe to assume its size fits into a size_t. At the same time, the opencoded Windows path conversion functions are all unified into a single helper function. Signed-off-by: David Oberhollenzer

Fix: Move LZO compressor from libsquashfs to libcommon

2019-11-24T00:03:10+00:00

The liblzo2 library is licensed under GPLv2, so it is not possible to distribute binaries of libsquashfs that link against liblzo2 under LGPL. This commit moves the LZO compressor implementation to libcommon, where this isn't a problem, since the tools themselves are licensed under GPLv3. It removes the ability of libsquashfs to read or generate LZO compressed SquashFS images, but the tools still can. Signed-off-by: David Oberhollenzer
