* Avoid passing the variable `tl' to functions that just use it forIan Dowse2001-12-181-22/+22
| | | | | | | | | | | | | | | | temporary storage. In the old NFS code it wasn't at all clear if the value of `tl' was used across or after macro calls, but I'm fairly confident that the convention was to keep its use local. Each ex-macro function now uses a local version of this variable, so all of the double-indirection goes away. The only exception to the `local use' rule for `tl' is nfsm_clget(), which is left unchanged by this commit. Reviewed by: peter Notes: svn path=/head/; revision=88091
* Unwind some more macros. NFSMADV() was kinda silly since it was rightPeter Wemm2001-09-281-77/+63
| | | | | | | | | | | | | next to equivalent m_len adjustments. Move the nfsm_subs.h macros into groups depending on which phase they are used in, since that affects the error recovery requirements. Collect some of the common error checking into a single macro as preparation for unwinding some more. Have nfs_rephead return a value instead of secretly modifying args. Remove some unused function arguments that were being passed around. Clarify nfsm_reply()'s error handling (I hope). Notes: svn path=/head/; revision=84079

* * Rename M_WAIT mbuf subsystem flag to M_TRYWAIT.Bosko Milekic2000-12-211-3/+3
| | | | | | | | | | | | | | | | | | | | | 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. Notes: svn path=/head/; revision=70254
* Problem to avoid processes getting stuck in "vmopar". From Ian'sDavid Malone2000-10-241-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | mail: The problem seems to originate with NFS's postop_attr information that is returned with a read or write RPC. Within a vm_fault context, the code cannot deal with vnode_pager_setsize() shrinking a vnode. The workaround in the patch below stops the nfsm_postop_attr() macro from ever shrinking a vnode. If the new size in the postop_attr information is smaller, then it just sets the nfsnode n_attrstamp to 0 to stop the wrong size getting used in the future. This change only affects postop_attr attributes; the nfsm_loadattr() macro works as normal. The change is implemented by adding a new argument to nfs_loadattrcache() called 'dontshrink'. When this is non-zero, nfs_loadattrcache() will never reduce the vnode/nfsnode size; instead it zeros n_attrstamp. There remain other was processes can get stuck in vmopar.

* Don't over-allocate and over-copy shorter NFSv2 filehandles and thenPeter Wemm1999-08-041-10/+11
| | | | | | | | | | | | | correct the pointers afterwards. It's kinda bogus that we generate a 24 (?) byte filehandle (2 x int32 fsid and 16 byte VFS fhandle) and pad it out to 64 bytes for NFSv3 with garbage. The whole point of NFSv3's variable filehandle length was to allow for shorter handles, both in memory and over the wire. I plan on taking a shot at fixing this shortly.

* Eradicate the variable "time" from the kernel, using various measures.Poul-Henning Kamp1998-03-301-9/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | "time" wasn't a atomic variable, so splfoo() protection were needed around any access to it, unless you just wanted the seconds part. Most uses of time.tv_sec now uses the new variable time_second instead. gettime() changed to getmicrotime(0. Remove a couple of unneeded splfoo() protections, the new getmicrotime() is atomic, (until Bruce sets a breakpoint in it). A couple of places needed random data, so use read_random() instead of mucking about with time which isn't random. Add a new nfs_curusec() function. Mark a couple of bogosities involving the now disappeard time variable. Update ffs_update() to avoid the weird "== &time" checks, by fixing the one remaining call that passwd &time as args. Change profiling in ncr.c to use ticks instead of time. Resolution is the same. Add new function "tvtohz()" to avoid the bogus "splfoo(), add time, call hzto() which subtracts time" sequences.

* Changes to support version 3 of the NFS protocol.Doug Rabson1995-06-271-90/+243
| | | | | | | | | | | | | | | | | | | | | The version 2 support has been tested (client+server) against FreeBSD-2.0, IRIX 5.3 and FreeBSD-current (using a loopback mount). The version 2 support is stable AFAIK. The version 3 support has been tested with a loopback mount and minimally against an IRIX 5.3 server. It needs more testing and may have problems. I have patched amd to support the new variable length filehandles although it will still only use version 2 of the protocol. Before booting a kernel with these changes, nfs clients will need to at least build and install /usr/sbin/mount_nfs. Servers will need to build and install /usr/sbin/mountd. NFS diskless support is untested. Obtained from: Rick Macklem <rick@snowhite.cis.uoguelph.ca> Notes: svn path=/head/; revision=9336
