plunky fd7356a917 Convert socket options code to use a sockopt structure 
instead of laying everything into an mbuf.

approved by core
 2008-08-06 15:01:23 +00:00
ad 15e29e981b Merge the socket locking patch: 
- Socket layer becomes MP safe.
- Unix protocols become MP safe.
- Allows protocol processing interrupts to safely block on locks.
- Fixes a number of race conditions.

With much feedback from matt@ and plunky@.

yamt febe85111f - remove nfs_exit exit hook. ok'ed by christos@. 
- as far as i understand the code, it shouldn't be necessary
	  because nfs_request can't return without removing its request
	  and r->r_lwp is either curlwp or NULL.
	- even if it's necessary, leaking requests is not the correct way
	  to recover from the condition.
- nfs_request: add a related assertion.

yamt e4c778084c - nfs_reply: keep rcvlock longer so that lwp which already have its reply 
received won't be stuck in nfs_receive.
- nfs_rcvlock: check exceptions before sleeping on the lock.
- nfs_rcvunlock: use cv_broadcast rather than cv_signal to ensure that
  lwps which received its reply get woken up.

kardel de4337ab21 merge FreeBSD timecounters from branch simonb-timecounters 
- struct timeval time is gone
  time.tv_sec -> time_second
- struct timeval mono_time is gone
  mono_time.tv_sec -> time_uptime
- access to time via
	{get,}{micro,nano,bin}time()
	get* versions are fast but less precise
- support NTP nanokernel implementation (NTP API 4)
- further reading:

rpaulo 5bb59eeab9 Back out revision 1.125 and 1.124. The code for checking if 
slp->ns_reclen == 0, was already there since "Linux sometimes
generates 0-lenght records.".

Bad Rui...

rpaulo 52dc289cfd In nfsrv_getstream(), ns_reclen will never be negative due to the

yamt ec5a93183a merge yamt-uio_vmspace branch. 
- use vmspace rather than proc or lwp where appropriate.
  the latter is more natural to specify an address space.
  (and less likely to be abused for random purposes.)
- fix a swdmover race.

just hand-off our reply to the thread which is holding the socket.
