Hi! I am taking a FreeBSD course this summer and I'm doing a homework. A new system call uidkill() is to be added. uidkill(uid_t uid, int signum) sends signal specified by signum to all processes owned by uid, excluding the calling process itself.
I'm almost done, however I get stuck with priv_check(). If the calling process is trying to send signal to processes owned by others, permission should be denied. My implementation simply uses an if (p->p_ucred->cr_uid == ksi.ksi_uid) to deny it, however priv_check() is required. My question is: what privilege a process should have to send signal to processes owned by others? PRIV_SIGNAL_DIFFCRED? -- View this message in context: http://freebsd.1045724.n5.nabble.com/priv-check-question-tp4549149p4549149.html Sent from the freebsd-hackers mailing list archive at Nabble.com. _______________________________________________ [email protected] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "[email protected]"
