GoSquashfs

A PURE Go library to read and write squashfs. Right now I'm focusing on unsquashing. Currently IS NOT a functional library. Some things that are currently public IS going to become private. Not very well documented either.

Special thanks to https://dr-emann.github.io/squashfs/ for some VERY important information in an easy to understand format. Thanks also to distri's squashfs library as I referenced it to figure some things out (and double check others).

Working

• Reading the header
• Reading metadata blocks (whether encrypted or not)
• Reading inodes
• Reading directories
• Basic gzip compression (Shouldn't be too hard to implement other, but for right now, this works)
• Listing all files via a string slice

Not Working (Yet). Roughly in order.

• Figure out fragments
• Extracting files
  • from inodes.
  • from path.
  • from file info.
• Give a list of files
  • In io.FileStat (?) form
• Reading the UID, GUID, Xatt, Compression Options, Export, and Fragment tables.
• Implement other compression types (Should be relatively easy)
• Squashing

Where I'm at.

• Reading fragments does not seem to be working right now
