* Store a unique ID, an interface index, rather than a pointer to thempi2015-06-161-2/+2
| | | | | | | | | | | | | | | receiving interface in the packet header of every mbuf. The interface pointer should now be retrieved when necessary with if_get(). If a NULL pointer is returned by if_get(), the interface has probably been destroy/removed and the mbuf should be freed. Such mechanism will simplify garbage collection of mbufs and limit problems with dangling ifp pointers. Tested by jmatthew@ and krw@, discussed with many. ok mikeb@, bluhm@, dlg@

* First step towards making uiomove() take a size_t size argument:miod2015-02-101-2/+2
| | | | | | | - rename uiomove() to uiomovei() and update all its users. - introduce uiomove(), which is similar to uiomovei() but with a size_t. - rewrite uiomovei() as an uiomove() wrapper. ok kettenis@

* If the v_type is going to change when loading the NFS attribute cache,jsing2013-11-271-1/+2
| | | | | | | | | purge the vnode from the namecache first. This prevents cache_purge() from later getting confused and trying to cache_zap() a namecache entry multiple times over, due to cache_zap() believing that the entry does not need to be removed from the vnode destinations queue. ok beck@
* Switch time_t, ino_t, clock_t, and struct kevent's ident and dataguenther2013-08-131-6/+4
| | | | | | | | | | | | | | | | | | | | members to 64bit types. Assign new syscall numbers for (almost all) the syscalls that involve the affected types, including anything with time_t, timeval, itimerval, timespec, rusage, dirent, stat, or kevent arguments. Add a d_off member to struct dirent and replace getdirentries() with getdents(), thus immensely simplifying and accelerating telldir/seekdir. Build perl with -DBIG_TIME. Bump the major on every single base library: the compat bits included here are only good enough to make the transition; the T32 compat option will be burned as soon as we've reached the new world are are happy with the snapshots for all architectures. DANGER: ABI incompatibility. Updating to this kernel requires extra work or you won't be able to login: install a snapshot instead. Much assistance in fixing userland issues from deraadt@ and tedu@ and build assistance from todd@ and otto@

* End the VOP experiment. Instead of the ridicolusly complicated operationthib2010-09-061-6/+6
| | | | | | | | | | | | | | | | | | | vector setup that has questionable features (that have, as far as I can tell never been used in practice, atleast not in OpenBSD), remove all the gunk and favor a simple struct full of function pointers that get set directly by each of the filesystems. Removes gobs of ugly code and makes things simpler by a magnitude. The only downside of this is that we loose the vnoperate feature so the spec/fifo operations of the filesystems need to be kept in sync with specfs and fifofs, this is no big deal as the API it self is pretty static. Many thanks to armani@ who pulled an earlier version of this diff to current after c2k10 and Gabriel Kihlman on tech@ for testing. Liked by many. "come on, find your balls" deraadt@.
* clean up a few things that where left to rot after bob's vfs cache work.thib2010-05-191-3/+1
| | | | | | | sync a few comments to reality (or remove them), remove the cn_hash member from struct componentname, spacing. ok beck@

* move to having requests on a per nfsmount tailq instead of one global one.thib2009-08-251-11/+1
| | | | | | | | | | also make the rexmit timeout per nfsmount, and make sure to start/stop the timer appropriately. now the nfs_timer() only fires if there is work todo, not always at nfs_ticks (it did, even if there where no nfsmounts in the system!). OK blambert@
* Rework the way we do async I/O in nfs. Introduce separate buf queues forthib2009-08-201-2/+4
| | | | | | | | | | | | | | | | each mount, and when work is "found", peg an aiod to that mount todo the I/O. Make nfs_asyncio() a bit smarter when deciding when to do asyncio and when to force it sync, this is done by keeping the aiod's one two lists, an "idle" and an "all" list, so asyncio is only done when there are aiods hanging around todo it for us or are already pegged to the mount. Idea liked by at least beck@ (and I think art@). Extensive testing done by myself and jasper and a few others on various arch's. Ideas/Code from Net/Free. OK blambert@.

| | | | | | | | | | but extensive performance benchmarking done by myself and jasper@ has shown that it doesn't help, at all - even on vaxens and in some cases it makes things significantly slower. "this excites me sexually" jetpack@ Tested by jasper@. OK blambert@
* group all of the on-stack variables that are uses by the nfsm_macrosthib2009-08-041-14/+7
| | | | | | | | | | | | | | to keep the data munging "state" into an nfsm_info structure. Each function now has this structure on its stack, and it and its members are now passed around so that the macros/functions can work there magic. this will make removing the nfsm_* macros way easier. Idea/code picked up from DragonflyBSD. Tested by krw@, jacekm@ and myself. OK blambert@.

* Remove the VREF() macro and replaces all instances with a call to verf(),thib2009-07-091-2/+2
| | | | | | | | | | | which is exactly what the macro does. Macro's that are nothing more then: #define FUNCTION(arg) function(arg) are almost always pointless and should go away. OK blambert@ Agreed by many.

* Start reworking NFS client mbuf handling by creating an interface whichblambert2009-01-201-8/+5
| | | | | | | | | | | | | requires well-formed mbuf chains to work. Existing function name is now a wrapper to this interface. Much, much more work to follow which will build on this. Truly change we can believe in. ok thib@, who would have preferred this in two commits, but I'm impatient :) testing on multiple arches (i386, arm, amd64, and sparc64 at least) by many, thanks to all who did so
