Cleanup and split of nfs client and server code.

This builds on the top of several repo-copies.

KSE Milestone 2

2001-09-12T08:38:13Z

Note ALL MODULES MUST BE RECOMPILED make the kernel aware that there are smaller units of scheduling than the process. (but only allow one thread per process at this time). This is functionally equivalent to teh previousl -current except that there is a thread associated with each process. Sorry john! (your next MFC will be a doosie!)

Switch to using a struct xucred instead of a struct xucred when not

actually in the kernel. This structure is a different size than what is currently in -CURRENT, but should hopefully be the last time any application breakage is caused there. As soon as any major inconveniences are removed, the definition of the in-kernel struct ucred should be conditionalized upon defined(_KERNEL). This also changes struct export_args to remove dependency on the constantly-changing struct ucred, as well as limiting the bounds of the size fields to the correct size. This means: a) mountd and friends won't break all the time, b) mountd and friends won't crash the kernel all the time if they don't know what they're doing wrt actual struct export_args layout.

* Rename M_WAIT mbuf subsystem flag to M_TRYWAIT.

2000-12-21T21:44:31Z

This is because calls with M_WAIT (now M_TRYWAIT) may not wait forever when nothing is available for allocation, and may end up returning NULL. Hopefully we now communicate more of the right thing to developers and make it very clear that it's necessary to check whether calls with M_(TRY)WAIT also resulted in a failed allocation. M_TRYWAIT basically means "try harder, block if necessary, but don't necessarily wait forever." The time spent blocking is tunable with the kern.ipc.mbuf_wait sysctl. M_WAIT is now deprecated but still defined for the next little while. * Fix a typo in a comment in mbuf.h * Fix some code that was actually passing the mbuf subsystem's M_WAIT to malloc(). Made it pass M_WAITOK instead. If we were ever to redefine the value of the M_WAIT flag, this could have became a big problem.

Convert more malloc+bzero to malloc+M_ZERO.

This patchset fixes a large number of file descriptor race conditions.

2000-11-18T21:01:04Z

Pre-rfork code assumed inherent locking of a process's file descriptor array. However, with the advent of rfork() the file descriptor table could be shared between processes. This patch closes over a dozen serious race conditions related to one thread manipulating the table (e.g. closing or dup()ing a descriptor) while another is blocked in an open(), close(), fcntl(), read(), write(), etc...
