libsqfs: add a threshold for extended directory inodes with index

2024-01-24T08:56:10+00:00

mksquashfs generates extended inodes if a directory contains 256 entries. libsquashfs so far only generated extended inodes if there is no other way to encode it. Mimic the behaviour of mksquashfs by adding a threshold. For this to work, the "sqfs_inode_set_xattr_index" function has to be changed to not immediately try to demote inodes to basic types. The fstree serialization is modified to do that itself if the index is 0xFFFFFFFF and the target is not a directory inode. Signed-off-by: David Oberhollenzer

Only use available CPUs

2022-11-04T12:03:23+00:00

Not all CPUs may be available for the current process. Some CPUs may be offline, others may not be included in the process affinity mask. In such cases too many threads will be created, which will then compete unnecessarily for CPU time. Use sched_getaffinity() to determine the correct number of threads to create.

Return an error number from sqfs_tree_find_hard_links

2022-08-20T12:45:16+00:00

Instead of printing error messages to stderr, simply return an error number instead, that the caller then prints out using sqfs_perror. The underlying rbtree already uses sqfs error numbers, so little change is needed here. Signed-off-by: David Oberhollenzer

Make sqfs_tree_node_get_path more robust

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

Test against various invariants: - Every non-root node must have a name - The root node muts not have a name - The name must not be ".." or "." - The name must not contain '/' - The loop that chases parent pointers must terminate, i.e. we must never reach the starting state again (link loop). Furthermore, make sure the sum of all path components plus separators does not overflow. Signed-off-by: David Oberhollenzer

Cleanup: move inode_stat to sqfs2tar

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

After trying removing many instances of `struct stat`, there is only one user of inode_stat left, so move the function there. Signed-off-by: David Oberhollenzer
