Fix win32 filename sanitation for cases were we have clashes

2024-02-14T08:21:30+00:00

We fix filenames containing components like COM1 or PRN by appending an underscore ('_'). A squashfs archive may contain files that already have such a modifed name (e.g. COM1_) which would now potentially clash. This is fixed by matching any number of trailing '_' characters for the bad name and adding another one. So all existing names that start with an illegal prefix and have any number of underscores, will always have an additional one appended. Signed-off-by: David Oberhollenzer

Add utility function to fixup Windows file paths

2024-02-09T14:59:37+00:00

The idea is to iterate over a (canonicalized) path with forward slashes by components, i.e. file and directory names. Each name is then looked at by iterating over components, i.e. everything between dots. If a component is an illegal name, like COM1 or AUX, we add an underscore. If it contains illegal characters, like : or \, we re-map that character into unicode private use area. Signed-off-by: David Oberhollenzer

Add a single, central base64 decoder

2022-11-17T23:58:13+00:00

Similar to the hex blob decoder, we need this once for tar and once for the filemap xattr parser. Simply add a single, central implementation to libutil, with a simple unit test, and then use it in both libtar and gensquashfs. Signed-off-by: David Oberhollenzer

Add a single, central hex blob decoder

2022-11-17T23:58:07+00:00

Since we need it twice (once for tar, once for the filemap xattr parser), add a single, central implementation to libutil, add a unit test for that implementation and then use it in both libtar and gensquashfs. Signed-off-by: David Oberhollenzer

block writer: move block comaprison to utility function

2022-09-20T06:47:02+00:00

Slightly modify the byte-for-byte comparison function to compare an arbitrary range in a file and move it to libutil. Instead of calling it for each block in the block writer, simply let it check an entire range in the block writer and compute the range position/size of the reference ahead, before looking for potential matches.
