TODO: I am seriously considering following Chet and changing the way this works, by explicitly dropping privs unless the shell is run with -p. Every other shell does it like mksh, except Heirloom sh, which on the other hand doesn’t know any explicit set -p or set +p (though it doesn’t know set +foo for any foo either). ┌──┤ QUESTION: Do we need the ability to do this: │ tg@blau:~ $ ./suidmksh -p -c 'whoami; set +p; whoami' │ root │ tg If not, I’m seriously considering to drop set ±p as well, only parse -p on the command line, with +p being the default, and dropping FPRIVILEGED. Thanks to RT for noticing and jilles for initial follow-up discussion, as well as Chet Ramey for doing the sane/secure thing instead of following Debian.
