| | | | | | | | | struct ucred; struct process then directly links to the ucred Based on a discussion at c2k10 or so before noting that FreeBSD and NetBSD did this too. ok matthew@

* Correct the links between threads, processes, pgrps, and sessions,guenther2010-07-261-3/+4
| | | | | | | | | so that the process-level stuff is to/from struct process and not struct proc. This fixes a bunch of problem cases in rthreads. Based on earlier work by blambert and myself, but mostly written at c2k10. Tested by many: deraadt, sthen, krw, ray, and in snapshots

| | | | | | fix the acct_*() code so that we always have a proc to lock on. ok pedro@
* This moves access to wall and uptime variables in MI code,tholo2004-06-241-5/+4
| | | | | | | | | | | | | | encapsulating all such access into wall-defined functions that makes sure locking is done as needed. It also cleans up some uses of wall time vs. uptime some places, but there is sure to be more of these needed as well, particularily in MD code. Also, many current calls to microtime() should probably be changed to getmicrotime(), or to the {,get}microuptime() versions. ok art@ deraadt@ aaron@ matthieu@ beck@ sturm@ millert@ others "Oh, that is not your problem!" from miod@

* change arguments to suser. suser now takes the process, and a flagstedu2003-08-151-2/+2
| | | | | | | | | argument. old cred only calls user suser_ucred. this will allow future work to more flexibly implement the idea of a root process. looks like something i saw in freebsd, but a little different. use of suser_ucred vs suser in file system code should be looked at again, for the moment semantics remain unchanged. review and input from art@ testing and further review miod@
* Remove the advertising clause in the UCB license which Berkeleymillert2003-06-021-6/+2
| | | | rescinded 22 July 1999. Proofed by myself and Theo.
* Move the accounting disk space watcher into a kernel thread.art2001-11-021-50/+62
| | | | | | Since we do filesystem operations, we need process context. This should fix accounting on nfs.
* Don't set filesize limit to infinity on exit.art2000-05-051-3/+22
| | | | | | | This is only needed in accounting and has to be done carefully because the limit structures are shared between processes. Found by Denis A. Doroshenko, analysed by Hannah Schroeter.

* Return EINVAL when msg_iovlen or iovcnt <= 0; Make uio_resid unsigned (size_t) and don't return EINVAL if it is < 0 in sys_{read,write}.
