Function kernel_walks_alike 

Source 
fn kernel_walks_alike(pid: u32, dirfd: i32, path: &[u8], host: &[u8]) -> bool
Expand description

Whether the kernel, walking path from the tracee’s dirfd by itself, reaches host.

The descriptor is a host directory already, so a path that joins onto it with nothing to translate on the way (no symlink among its components, which canonicalization would have resolved) needs no rewrite.

§Arguments

  • pid - Tracee thread id.
  • dirfd - A directory descriptor of the tracee.
  • path - Path relative to it, as the tracee passed it.
  • host - What translation resolved it to.
