* Upon further reflection, back out previous commit, partly for the reasonsDag-Erling Smørgrav2001-10-221-0/+7

* Clear the p_stops field on change of user/group id, unless the correctSean Eric Fagan1997-12-201-2/+2
| | | | | | | | | | | | flag is set in the p_pfsflags field. This, essentially, prevents an SUID proram from hanging after being traced. (E.g., "truss /usr/bin/rlogin" would fail, but leave rlogin in a stopevent state.) Yet another case where procctl is (hopefully ;)) no longer needed in the general case.

* Explicitly use the _IOC macro directly. This changes the ioctl commandSean Eric Fagan1997-12-151-5/+5

* Change the ioctls for procfs around a bit; in particular, whever possible,Sean Eric Fagan1997-12-131-6/+7
| | | | | | | | | | | | | | | | | change from ioctl(fd, PIOC<foo>, &i); to ioctl(fd, PIOC<foo>, i); This is going from the _IOW to _IO ioctl macro. The kernel, procctl, and truss must be in synch for it all to work (not doing so will get errors about inappropriate ioctl's, fortunately). Hopefully I didn't forget anything :).

* A couple of fixes from bruce: first of all, psignal is a void (stupidSean Eric Fagan1997-12-081-2/+2
| | | | | | | | | | | me; unfortunately, also makes it hard ot check for errors); second, I had managed to forget a change to PIOCSFL (it should be _IOW, not _IOR) I had in my local copy, and Bruce called me on it. Submitted by: bde Notes: svn path=/head/; revision=31636
