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

Only check for OS specific bad filenames when unpacking

2019-12-09T14:56:01+00:00

When converting a SquashFS image to a tarball, it makes no sense to refuse conversion if the filename is considered evil by the OS. This patch adds an option to is_filename_sane to check if the OS has a problem with the given file name. sqfs2tar sets it to false and converts everything while rdsquashfs sets it to true when unpacking.
