Module translate 

Translating a tracee’s (dirfd, path) into the object to act on, or into a host path, and back.

Functions

detranslate_path

Translates a host path back into the guest’s view (for readlink on /proc magic links and getcwd).

guest_cwd

The guest path of a tracee’s working directory.

guest_dirfd_path

The guest path of dirfd itself, or of the tracee’s cwd for AT_FDCWD: what an empty path names in the calls that allow one (AT_EMPTY_PATH, and readlinkat always).

guest_fd_path

Reads the guest path of a tracee’s open directory descriptor.

read_link

readlink(2) on a host path, as bytes.

strip_deleted

Drops the (deleted) marker /proc appends to links of unlinked targets.

translate

Translates a path as seen by a tracee into the object to operate on.

translate_path

Translates a path as seen by a tracee into a textual host path, for the callers that hand the path to a program or to the tracee itself (the exec plan, the ptrace tier’s in-place rewrites): the kernel then resolves it again on the host.
