Thanks! I am testing a patch (without auxv vector so far) and have some questions. Original ps -e returns environment only for user owned processes (the access is restricted by the permissions of /proc/pid/mem file). My kern.proc.env sysctl does not have such a restriction. I suppose I should add it? What function I could use for this? BTW, linprocfs allows to read other user's environment.

Or do you propose to extend struct ps_strings to store location and size of auxv? I could do this way... -- Mikolaj Golub _______________________________________________ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "freebsd-hackers-unsubscr...@freebsd.org"
