Message-ID: <1505075168.5111.45.camel@bitron.ch> (raw)
Hi Al,
Might it make sense to specify these lookup restrictions when opening
the directory (O_ROOT?) instead of specifying it for each lookup with
AT_* (or supporting both)? This might make it more useful when passing
directory fds between processes that do not use seccomp (where
AT_BENEATH could be enforced).
For my sandboxing use case, I'd be happy with either solution, though.
Is there anything I can do to help move this forward?
Best regards,
Jürg
