Module permissions::functions

Permission checks at some path using access_syscall.

Having permission of reading, writing, executing or deleting a file does not guarantee success in doing so, it is unlikely but IO can fail.

Also be careful with TOCTOU race conditions, when you have outdated file system information that has changed since the last check.
