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: libsqfs: move directory iteration out of the directory reader

2022-06-02T15:26:53+00:00

Add a simple directory state object to the meta data reader and use that to iterate directory entries. The code for reading the directory listing is movde to readdir.c Signed-off-by: David Oberhollenzer

Add support for '.' and '..' entries in sqfs_dir_reader_t

2022-04-09T21:26:13+00:00

Two flags are added to the dir reader API, one for the create function that the dir reader should report those entries and one to the open function to suppress that if it was enabled. To implement the feature, a mapping of visited directory inodes is maintained internally, that mapps inode numbers to inode references. When opening a directory, state is maintained to generate the fake entries for '.' and '..'. Since all the other functions are based on the open/read/rewind API, no alterations need to be made. The tree scan function is modified, to use the suppress flag, so it does not accidentally catch those entries. Signed-off-by: David Oberhollenzer
