driver(9): Make vdevgone call config_detach_commit if appropriate.

Revert the changes made in February to make cwdinfo use mostly lockless, which relied on taking extra vnode refs. Having benchmarked various experimental changes over the past few months it seems that it's better to avoid vnode refs as much as possible. cwdi_lock as a RW lock already did that to some extent for getcwd() and will permit the same for namei() too.

Merge from ad-namecache: - Have a stab at clustering the members of vnode_t and vnode_impl_t in a more cache-conscious way. With that done, go back to adjusting v_usecount with atomics and keep vi_lock directly in vnode_impl_t (saves KVA). - Allow VOP_LOCK(LK_NONE) for the benefit of VFS_VGET() and VFS_ROOT(). Make sure LK_UPGRADE always comes with LK_NOWAIT. - Make cwdinfo use mostly lockless.

Minor vnode locking changes: - Stop using atomics to maniupulate v_usecount. It was a mistake to begin with. It doesn't work as intended unless the XLOCK bit is incorporated in v_usecount and we don't have that any more. When I introduced this 10+ years ago it was to reduce pressure on v_interlock but it doesn't do that, it just makes stuff disappear from lockstat output and introduces problems elsewhere. We could do atomic usecounts on vnodes but there has to be a well thought out scheme. - Resurrect LK_UPGRADE/LK_DOWNGRADE which will be needed to work effectively when there is increased use of shared locks on vnodes. - Allocate the vnode lock using rw_obj_alloc() to reduce false sharing of struct vnode. - Put all of the LRU lists into a single cache line, and do not requeue a vnode if it's already on the correct list and was requeued recently (less than a second ago).

A vnode is usually called "active", if it has an associated file system node and a usecount greater zero. Therefore rename state "VS_ACTIVE" to "VS_LOADED" and add a new synthetic state "VS_ACTIVE" for VSTATE_ASSERT() to assert an active vnode. Add VSTATE_ASSERT_UNLOCKED() to be used with v_interlock unheld and move the state assertion macros to sys/vnode_impl.h.

C99 section 6.7.2.3 (Tags) Note 3 states that: A type specifier of the form enum identifier without an enumerator list shall only appear after the type it specifies is complete. which means that we cannot pass an "enum vtype" argument to kauth_access_action() without fully specifying the type first. Unfortunately there is a complicated include file loop which makes that difficult, so convert this minimal function into a macro (and capitalize it). (ok elad@)

Make the spec_node table implementation private to spec_vnops.c. To retrieve a spec_node, two new lookup functions (by device or by mount) are implemented. Both return a referenced vnode, for an opened block device the opened vnode is returned so further diagnostic checks "vp == ... sd_bdevvp" will not fire. Otherwise any vnode matching the criteria gets returned. No objections on tech-kern. Welcome to 6.99.17

merge the bouyer-quota2 branch. This adds a new on-disk format to store disk quota usage and limits, integrated with ffs metadata. Usage is checked by fsck_ffs (no more quotacheck) and is covered by the WAPBL journal. Enabled with kernel option QUOTA2 (added where QUOTA was enabled in kernel config files), turned on with tunefs(8) on a per-filesystem basis. mount_mfs(8) can also turn quotas on. See http://mail-index.netbsd.org/tech-kern/2011/02/19/msg010025.html for details.

Snapshot of work in progress on a modernised disk quota system:
- new quotactl syscall (versionned for backward compat), which takes
as parameter a path to a mount point, and a prop_dictionary
(in plistref format) describing commands and arguments.
For each command, status and data are returned as a prop_dictionary.
quota commands features will be added to take advantage of this,
exporting quota data or getting quota commands as plists.
- new on disk-format storage (all 64bit wide), integrated to metadata for
ffs (and playing nicely with wapbl).
Quotas are enabled on a ffs filesystem via superblock flags.
tunefs(8) can enable or disable quotas.
On a quota-enabled filesystem, fsck_ffs(8) will track per-uid/gid
block and inode usages, and will check and update quotas in Pass 6.
quota usage and limits are stored in unliked files (one for users,
one for groups)l fsck_ffs(8) will create the files if needed, or
free them if needed. This means that after enabling or disabling
quotas on a filesystem; a fsck_ffs(8) run is required.
quotacheck(8) is not needed any more, on a unclean shutdown
fsck or journal replay will take care of fixing quotas.
newfs(8) can create a ready-to-mount quota-enabled filesystem
(superblock flags are set and quota inodes are created).
Other new features or semantic changes:
- default quota datas, applied to users or groups which don't already
have a quota entry
- per-user/group grace time (instead of a filesystem global one)
- 0 really means "nothing allowed at all", not "no limit".
If you want "no limit", set the limit to UQUAD_MAX (tools will
understand "unlimited" and "-")
A quota file is structured as follow:
it starts with a header, containing a few per-filesystem values,
and the default quota limits.
Quota entries are linked together as a simple list, each entry has a
pointer (as an offset withing the file) to the next.
The header has a pointer to a list of free quota entries, and
a hash table of in-use entries. The size of the hash table depends
on the filesystem block size (header+hash table should fit in the
first block). The file is not sparse and is a multiple of
filesystem block size (when the free quota entry list is empty a new
filesystem block is allocated). quota entries to not cross
filesystem block boundaries.
In memory, the kernel keeps a cache of recently used quota entries
as a reference to the block number, and offset withing the block.
The quota entry itself is keept in the buf cache.
fsck_ffs(8), tunefs(8) and newfs(8) supports are completed (with
related atf tests :)
The kernel can update disk usage and report it via quotactl(2).
Todo: enforce quotas limits (limits are not checked by kernel yet)
update repquota, edquota and rpc.rquotad to the new world
implement compat_50_quotactl ioctl.
update quotactl(2) man page
fsck_ffs required fixes so that allocating new blocks or inodes will
properly update the superblock and cg sumaries. This was not an issue up
to now because superblock and cg sumaries check happened last, but now
allocations or frees can happen in pass 6.

Now that ffs on disk inodes get freed in the reclaim routine it is no longer necessary for vget() to handle VI_INACTNOW as a special case. Remove this check and its support in vrelel(). Getting another reference while the freelist is locked is an error. Replace the check with a KASSERT.

Remove KASSERT(vp->v_usecount == 1) in getnewvnode() and ungetnewvnode(). Another process could be vget()ing the vnode and bump v_usecount while getcleanvnode() is vclean()ing it (as vclean drops the interlock). vget() will then wait for VI_XLOCK or VI_FREEING to clear; and we could test this assertion while the other process is still slepping. We could even end up in ungetnewvnode() before this other process got a chance to run.

set VI_XLOCK (too late to be noticed by the competing thread)
wait on the vnode lock (this might violate locking order)
the use of a flag bit was suggested by Andrew Doran. PR/41374.

Keep a generation number, mountgen, that increases every time a filesystem is mounted. Synchronize access to the number with a mutex. When a struct mount, mp, is allocated, assign the current generation number to mp->mnt_gen. Introduce vfs_unmount_forceone() that forcefully unmounts the most recently mounted filesystem. Refactor: extract vfs_shutdown1() from vfs_shutdown(). Extract vfs_sync_all() from vfs_shutdown1(). Print more progress indications while we're unmounting all of the filesystems during shutdown. We increase the reference count on mp before calling dounmount(mp), but we do not decrease it if dounmount(mp) fails, and neither does dounmount(mp). So decrease the reference count if dounmount(mp) fails. Change the loop terminating condition in vfs_unmountall1() to (mp != (void *)&mountlist) from !CIRCLEQ_EMPTY(&mountlist), because we may not ever empty the list, especially if we're not forcing the filesystems to unmount.

Move the implementation of vaccess() to genfs_can_access(), in line with the other routines of the same spirit. Adjust file-system code to use it. Keep vaccess() for KPI compatibility and to keep element of least surprise. A "diagnostic" message warning that vaccess() is deprecated will be printed when it's used (obviously, only in DIAGNOSTIC kernels).

Extract common code from vfs_rootmountalloc(9) and mount_domount() into a new struct mount-allocation routine, vfs_mountalloc(9). Documentation updates will follow. Attention: Synchronization Oversight Committee! In mount_domount(), I postpone the call mutex_enter(&mp->mnt_updating) until right before the VFS_MOUNT(9) call because (1) that looks to me like the earliest possible opportunity for mp to become visible to any other LWP, because it was just kmem_zalloc(9)'d and (2) it made extracting the common code much easier. Tell me if my reasoning is faulty.

Store config(1)'s root filesystem type as a text string rather than embedding the address of its xxx_mountroot() in swapnetbsd.c. This permits booting of kernels with hard-wired filesystem type even if the filesystem is in a loadable module (ie, not linked into the kernel image). Discussed on current-users. Tested on amd64 and i386 with both hard- wired and '?' filesystem times, and on both modular and monolithic kernels. Thanks to pooka@ for code review and suggestions. Addresses my PR kern/40167

Per discussion with ad, remove most of the #include <sys/sa.h> lines as they were including sa.h just for the type(s) needed for syscallargs.h. Instead, create a new file, sys/satypes.h, which contains just the types needed for syscallargs.h. Yes, there's only one now, but that may change and it's probably more likely to change if it'd be difficult to handle. :-) Per discussion with matt at n dot o, add an include of satypes.h to sigtypes.h. Upcall handlers are kinda signal handlers, and signalling is the header file that's already included for syscallargs.h that closest matches SA. This shaves about 3000 lines off of the diff of the branch relative to the base. That also represents about 18% of the total before this checkin. I think this reduction is very good thing.

Initial checkin of re-adding SA. Everything except kern_sa.c compiles in GENERIC for i386. This is still a work-in-progress, but this checkin covers most of the mechanical work (changing signalling to be able to accomidate SA's process-wide signalling and re-adding includes of sys/sa.h and savar.h). Subsequent changes will be much more interesting. Also, kern_sa.c has received partial cleanup. There's still more to do, though.

PR kern/38141 lookup/vfs_busy acquire rwlock recursively Simplify the mount locking. Remove all the crud to deal with recursion on the mount lock, and crud to deal with unmount as another weirdo lock. Hopefully this will once and for all fix the deadlocks with this. With this commit there are two locks on each mount: - krwlock_t mnt_unmounting. This is used to prevent unmount across critical sections like getnewvnode(). It's only ever read locked with rw_tryenter(), and is only ever write locked in dounmount(). A write hold can't be taken on this lock if the current LWP could hold a vnode lock. - kmutex_t mnt_updating. This is taken by threads updating the mount, for example when going r/o -> r/w, and is only present to serialize updates. In order to take this lock, a read hold must first be taken on mnt_unmounting, and the two need to be held across the operation. One effect of this change: previously if an unmount failed, we would make a half hearted attempt to back out of it gracefully, but that was unlikely to work in a lot of cases. Now while an unmount that will be aborted is in progress, new file operations within the mount will fail instead of being delayed. That is unlikely to be a problem though, because if the admin requests unmount of a file system then s(he) has made a decision to deny access to the resource.

kern/38135 vfs_busy/vfs_trybusy confusion The symptom was that sometimes file systems would occasionally not appear in output from 'df' or 'mount' if the system was busy. Resolution: - Make mount locks work somewhat like vm_map locks. - vfs_trybusy() now only fails if the mount is gone, or if someone is unmounting the file system. Simple contention on mnt_lock doesn't cause it to fail. - vfs_busy() will wait even if the file system is being unmounted.

specfs changes for PR kern/37717 (raidclose() is no longer called on shutdown). There are still problems with device access and a PR will be filed. - Kill checkalias(). Allow multiple vnodes to reference a single device. - Don't play dangerous tricks with block vnodes to ensure that only one vnode can describe a block device. Instead, prohibit concurrent opens of block devices. As a bonus remove the unreliable code that prevents multiple file system mounts on the same device. It's no longer needed. - Track opens by vnode and by device. Issue cdev_close() when the last open goes away, instead of abusing vnode::v_usecount to tell if the device is open.

- Redo previous so that final release of vnodes by vrele() is only deferred if absolutely necessary. It might be beneficial in the long term to defer more often than not because it avoids a lot of calls to VOP_INACTIVE(). That would take some effort to get right and the intent with this change is just to make things work. - If a vnode gains and loses a reference while being deactivated, then call VOP_INACTIVE() again to make sure that it's correctly flushed.

Update the file system copy-on-write handler. - Instead of hooking the handler on the specdev of a mounted file system hook directly on the `struct mount'. - Rename from `vn_cow_*' to `fscow_*' and move to `kern/vfs_trans.c'. Use `mount_*specific' instead of clobbering `struct mount' or `struct specinfo'. - Replace the hand-made reader/writer lock with a krwlock. - Keep `vn_cow_*' functions and mark as obsolete. - Welcome to NetBSD 4.99.32 - `struct specinfo' changed size.

- Don't do proc_vmspace_getref() in dofileread() and friends. They only ever access the caller's vmspace so it's not going to go away. Instead just use curproc->p_vmspace. Fixes high lock contention during file I/O by multithreaded processes. Don't pass in lwp_t *l, it's confusing. - Drain cleaned vnodes from mountpoints just before checking to see if there are danglers. Cleaned vnodes now stick around on mountpoint lists until reused, as it's too expensive to pull them off earlier.

Checkpoint work in progress on the vnode lifecycle and reference counting stuff. This makes it work properly without kernel_lock and fixes a few quite old bugs. - When traversing a mountpoint vnode list, use a dummy marker vnode to track our current position. The old code relied on the assumption that vnodes are never freed from the system, which hasn't been true for a while. - Call VOP_INACTIVE() while we hold a reference to the vnode to avoid racing with other threads. Add a 'recycle' parameter to VOP_INACTIVE that's used to hint to vrele() that the vnode is no longer used and should be recycled immediatley. - Remove VI_FREEING which was used to by UFS to prevent an on-disk inode freed in ufs_inactive() from being reused before the vnode describing it was reclaimed. Instead, don't call UFS_VFREE() until we have removed the the node from the inode hash in ufs_reclaim(). - Track whether or not vnodes are clean. vrele() becomes the final resting place for vnodes; if the refcount drops to zero, free the vnode back to the pool. If it's dirty, put it back onto a freelist as before. As a result eliminate the vunwait() crap which was intended to prevent vnodes from disappearing while they were being waited on. - Always hold a reference to the vnode across calls to vgone() and vclean(). vgone() now automatically does a vrele() when complete, potentially freeing the vnode back to the pool. - Handle races where vnodes gain a reference while being cleaned out, inactivated and/or recycled. - Now that vnodes get released on a regular basis, allocate vnodes from a pool_cache. - Add more assertions.

introduce vrele2(), which allows to release vnodes the way lfs
sometimes wants it:

questionable optimization that isn't even enabled by default,

New file system suspension API to replace vn_start_write and vn_finished_write. The suspension helpers are now put into file system specific operations. This means every file system not supporting these helpers cannot be suspended and therefore snapshots are no longer possible. Implemented for file systems of type ffs. The new API is enabled on a kernel option NEWVNGATE. This option is not enabled by default in any kernel config. Presented and discussed on tech-kern with much input from Bill Studenmund <wrstuden@netbsd.org> and YAMAMOTO Takashi <yamt@netbsd.org>. Welcome to 4.99.9 (new vfs op vfs_suspendctl).

TAILQ_INIT a mountpoint's vnode queue and always add vnodes to the tail instead of an explicit check to add to the head for an empty queue. Apparently TAILQ_INSERT_HEAD happens to work for a non-initialized head and does implicit initialization so that TAILQ_INSERT_TAIL works after that.

Replace the LIST structure mp->mnt_vnodelist to a TAILQ structure since all vnodes were synced and processed backwards. This meant that the last accessed node was processed first and the earlierst last. An extra benefit is the removal of the ugly hack from the Berkly days on LFS. In the proces, i've also replaced the various variations hand written loops by the TAILQ_FOREACH() macro's.

vfs_mountedon() can only and only handle special device nodes and will otherwise generate an UVM trap or will access random memory. This is due to the dereference of vp->v_specmountpoint that is really vp->v_specinfo->si_mountpoint. The field v_specinfo is multiplexed with other structs in the vun union in struct vnode like struct socket. The patch adds a sanity check for accessing the specinfo fields by only allowing VBLK nodes to be passed. In theory also VCHR could be valid since its also a special node though mounting is only done on VBLK so be strict. Ok'd by yamt.

Pull up following revision(s) (requested by chs in ticket #10207): sys/kern/vfs_subr.c: revision 1.231 There is an annoying deadlock that goes like this: * Process A is closing one file descriptor belonging to a device. In doing so, ffs_update() is called and starts writing a block synchronously. (Note: This leaves the vnode locked. It also has other instances -- stdin, et al -- of the same device open, so v_usecount is definitely non-zero.) * Process B does a revoke() on the device. The revoke() has to wait for the vnode to be unlocked because ffs_update() is still in progress. * Process C tries to open() the device. It wedges in checkalias() repeatedly calling vget() because it returns EBUSY immediately. To fix, this: * checkalias() now uses LK_SLEEPFAIL rather than LK_NOWAIT. Therefore it will wait for the vnode to become unlocked, but it will recheck that it is on the hash list, in case it was in the process of being revoke()d or was revoke()d again before we were woken up. * Since we're relying on the vnode lock to tell us that the vnode hasn't been removed from the hash list *anyway*, I have moved the code to remove it into the DOCLOSE section of vclean(), inside the vnode lock. In the example at hand, process A was sh(1), process B was a child of init(8), and process C was syslogd(8).

Apply the NFS exports list rototill patch: - Remove all NFS related stuff from file system specific code. - Drop the vfs_checkexp hook and generalize it in the new nfs_check_export function, thus removing redundancy from all file systems. - Move all NFS export-related stuff from kern/vfs_subr.c to the new file sys/nfs/nfs_export.c. The former was becoming large and its code is always compiled, regardless of the build options. Using the latter, the code is only compiled in when NFSSERVER is enabled. While doing this, also make some functions in nfs_subs.c conditional to NFSSERVER. - Add a new command in nfssvc(2), called NFSSVC_SETEXPORTSLIST, that takes a path and a set of export entries. At the moment it can only clear the exports list or append entries, one by one, but it is done in a way that allows setting the whole set of entries atomically in the future (see the comment in mountd_set_exports_list or in doc/TODO). - Change mountd(8) to use the nfssvc(2) system call instead of mount(2) so that it becomes file system agnostic. In fact, all this whole thing was done to remove a 'XXX' block from this utility! - Change the mount*, newfs and fsck* userland utilities to not deal with NFS exports initialization; done internally by the kernel when initializing the NFS support for each file system. - Implement an interface for VFS (called VFS hooks) so that several kernel subsystems can run arbitrary code upon receipt of specific VFS events. At the moment, this only provides support for unmount and is used to destroy NFS exports lists from the file systems being unmounted, though it has room for extension. Thanks go to yamt@, chs@, thorpej@, wrstuden@ and others for their comments and advice in the development of this patch.

Rework the mountroot interface so that vfs_mountroot() opens the root device and just passes it on to the file system functions. This avoids opening and closing the device several times. Mentioned on tech-kern some time ago, IIRC. I've been running this for a long time.

Add a new VNODE_LOCKDEBUG option, which enables checks in the VOP_*() calls to ensure that the vnode lock state is as expected when the VOP call is made. Modify vnode_if.src to set the expected state according to the documenting lock table for each VOP. Modify vnode_if.sh to emit the checks. Notes: - The checks are only performed if the vnode has the VLOCKSWORK bit set. Some file systems (e.g. specfs) don't even bother with vnode locks, so of course the checks will fail. - We can't actually run with VNODE_LOCKDEBUG because there are so many vnode locking problems, not the least of which is the "use SHARED for VOP_READ()" issue, which screws things up for the entire call chain. Inspired by similar changes in OpenBSD, but implemented differently.

Undo part of the ktrace/lwp changes. In particular: * Remove the "lwp *" argument that was added to vget(). Turns out that nothing actually used it! * Remove the "lwp *" arguments that were added to VFS_ROOT(), VFS_VGET(), and VFS_FHTOVP(); all they did was pass it to vget() (which, as noted above, didn't use it). * Remove all of the "lwp *" arguments to internal functions that were added just to appease the above.

Fixing age old cruft: * Rather than using mnt_maxsymlinklen to indicate that a file systems returns d_type fields(!), add a new internal flag, IMNT_DTYPE. Add 3 new elements to ufsmount: * um_maxsymlinklen, replaces mnt_maxsymlinklen (which never should have existed in the first place). * um_dirblksiz, which tracks the current directory block size, eliminating the FS-specific checks littered throughout the code. This may be used later to make the block size variable. * um_maxfilesize, which is the maximum file size, possibly adjusted lower due to implementation issues. Sync some bug fixes from FFS into ext2fs, particularly: * ffs_lookup.c 1.21, 1.28, 1.33, 1.48 * ffs_inode.c 1.43, 1.44, 1.45, 1.66, 1.67 * ffs_vnops.c 1.84, 1.85, 1.86 Clean up some crappy pointer frobnication.

There is an annoying deadlock that goes like this: * Process A is closing one file descriptor belonging to a device. In doing so, ffs_update() is called and starts writing a block synchronously. (Note: This leaves the vnode locked. It also has other instances -- stdin, et al -- of the same device open, so v_usecount is definitely non-zero.) * Process B does a revoke() on the device. The revoke() has to wait for the vnode to be unlocked because ffs_update() is still in progress. * Process C tries to open() the device. It wedges in checkalias() repeatedly calling vget() because it returns EBUSY immediately. To fix, this: * checkalias() now uses LK_SLEEPFAIL rather than LK_NOWAIT. Therefore it will wait for the vnode to become unlocked, but it will recheck that it is on the hash list, in case it was in the process of being revoke()d or was revoke()d again before we were woken up. * Since we're relying on the vnode lock to tell us that the vnode hasn't been removed from the hash list *anyway*, I have moved the code to remove it into the DOCLOSE section of vclean(), inside the vnode lock. In the example at hand, process A was sh(1), process B was a child of init(8), and process C was syslogd(8).

Replace the traditional buffer memory management -- based on fixed per buffer virtual memory reservation and a private pool of memory pages -- by a scheme based on memory pools. This allows better utilization of memory because buffers can now be allocated with a granularity finer than the system's native page size (useful for filesystems with e.g. 1k or 2k fragment sizes). It also avoids fragmentation of virtual to physical memory mappings (due to the former fixed virtual address reservation) resulting in better utilization of MMU resources on some platforms. Finally, the scheme is more flexible by allowing run-time decisions on the amount of memory to be used for buffers. On the other hand, the effectiveness of the LRU queue for buffer recycling may be somewhat reduced compared to the traditional method since, due to the nature of the pool based memory allocation, the actual least recently used buffer may release its memory to a pool different from the one needed by a newly allocated buffer. However, this effect will kick in only if the system is under memory pressure.

Dynamic sysctl. Gone are the old kern_sysctl(), cpu_sysctl(), hw_sysctl(), vfs_sysctl(), etc, routines, along with sysctl_int() et al. Now all nodes are registered with the tree, and nodes can be added (or removed) easily, and I/O to and from the tree is handled generically. Since the nodes are registered with the tree, the mapping from name to number (and back again) can now be discovered, instead of having to be hard coded. Adding new nodes to the tree is likewise much simpler -- the new infrastructure handles almost all the work for simple types, and just about anything else can be done with a small helper function. All existing nodes are where they were before (numerically speaking), so all existing consumers of sysctl information should notice no difference. PS - I'm sorry, but there's a distinct lack of documentation at the moment. I'm working on sysctl(3/8/9) right now, and I promise to watch out for buses.

Apply the aborted ktrace-lwp changes to a specific branch. This is just for others to review, I'm concerned that patch fuziness may have resulted in some errant code being generated but I'll look at that later by comparing the diff from the base to the branch with the file I attempt to apply to it. This will, at the very least, put the changes in a better context for others to review them and attempt to tinker with removing passing of 'struct lwp' through the kernel.

Undo part of the ktrace/lwp changes. In particular: * Remove the "lwp *" argument that was added to vget(). Turns out that nothing actually used it! * Remove the "lwp *" arguments that were added to VFS_ROOT(), VFS_VGET(), and VFS_FHTOVP(); all they did was pass it to vget() (which, as noted above, didn't use it). * Remove all of the "lwp *" arguments to internal functions that were added just to appease the above.

Pass lwp pointers throughtout the kernel, as required, so that the lwpid can be inserted into ktrace records. The general change has been to replace "struct proc *" with "struct lwp *" in various function prototypes, pass the lwp through and use l_proc to get the process pointer when needed. Bump the kernel rev up to 1.6V

PR/1796: John Kohl: statfs misbehaves under chrooted environments. - Under chroot it displays only the visible filesystems with appropriate paths. - The statfs f_mntonname gets adjusted to contain the real path from root. - While was there, fixed a bug in ext2fs, locking problems with vfs_getfsstat(), and factored out some of the vfsop statfs() code to copy_statfs_info(). This fixes the problem where some filesystems forgot to set fsid. - Made coda look more like a normal fs.

Merge the gehenna-devsw branch into the trunk. This merge changes the device switch tables from static array to dynamically generated by config(8). - All device switches is defined as a constant structure in device drivers. - The new grammer ``device-major'' is introduced to ``files''. device-major <prefix> char <num> [block <num>] [<rules>] - All device major numbers must be listed up in port dependent majors.<arch> by using this grammer. - Added the new naming convention. The name of the device switch must be <prefix>_[bc]devsw for auto-generation of device switch tables. - The backward compatibility of loading block/character device switch by LKM framework is broken. This is necessary to convert from block/character device major to device name in runtime and vice versa. - The restriction to assign device major by LKM is completely removed. We don't need to reserve LKM entries for dynamic loading of device switch. - In compile time, device major numbers list is packed into the kernel and the LKM framework will refer it to assign device major number dynamically.

Pull up revision 1.175 (requested by perseant in ticket #132):
Back out rev 1.174 of vfs_subr.c, because the splbio() wasn't protecting
enough to be useful, and broadening it so that it did would have meant
that operations possibly requiring synchronous disk activity would have
to be done in splbio(). This clearly was not going to work.
Worked around this in the LFS case by having lfs_cluster_callback put an
extra hold on the vnode before calling biodone(), and taking the hold
off without HOLDRELE's problematic list swapping. lfs_vunref() will take
care of that---in thread context---on the next write if need be.
Also, ensure that the list walking in lfs_{writevnodes,segunlock,gather}
takes into account the possibility that the list may change
underneath it (possibly because it itself deleted an element).
Tested on i386, test-compiled on alpha.

Pool deals fairly well with physical memory shortage, but it doesn't deal with shortages of the VM maps where the backing pages are mapped (usually kmem_map). Try to deal with this: * Group all information about the backend allocator for a pool in a separate structure. The pool references this structure, rather than the individual fields. * Change the pool_init() API accordingly, and adjust all callers. * Link all pools using the same backend allocator on a list. * The backend allocator is responsible for waiting for physical memory to become available, but will still fail if it cannot callocate KVA space for the pages. If this happens, carefully drain all pools using the same backend allocator, so that some KVA space can be freed. * Change pool_reclaim() to indicate if it actually succeeded in freeing some pages, and use that information to make draining easier and more efficient. * Get rid of PR_URGENT. There was only one use of it, and it could be dealt with by the caller. From art@openbsd.org.

- Add a new vnode flag VEXECMAP, which indicates that a vnode has executable mappings. Stop overloading VTEXT for this purpose (VTEXT also has another meaning). - Rename vn_marktext() to vn_markexec(), and use it when executable mappings of a vnode are established. - In places where we want to set VTEXT, set it in v_flag directly, rather than making a function call to do this (it no longer makes sense to use a function call, since we no longer overload VTEXT with VEXECMAP's meaning). VEXECMAP suggested by Chuq Silvers.

Various changes to make cloning devices possible: * Add an extra argument (struct vnode **) to VOP_OPEN. If it is not NULL, specfs will create a cloned (aliased) vnode during the call, and return it there. The caller should release and unlock the original vnode if a new vnode was returned. The new vnode is returned locked. * Add a flag field to the cdevsw and bdevsw structures. DF_CLONING indicates that it wants a new vnode for each open (XXX is there a better way? devprop?) * If a device is cloning, always call the close entry point for a VOP_CLOSE. Also, rewrite cons.c to do the right thing with vnodes. Use VOPs rather then direct device entry calls. Suggested by mycroft@ Light to moderate testing done an i386 system (arch doesn't matter though, these are MI changes).

a whole bunch of changes to improve performance and robustness under load:
- remove special treatment of pager_map mappings in pmaps. this is
required now, since I've removed the globals that expose the address range.
pager_map now uses pmap_kenter_pa() instead of pmap_enter(), so there's
no longer any need to special-case it.
- eliminate struct uvm_vnode by moving its fields into struct vnode.
- rewrite the pageout path. the pager is now responsible for handling the
high-level requests instead of only getting control after a bunch of work
has already been done on its behalf. this will allow us to UBCify LFS,
which needs tighter control over its pages than other filesystems do.
writing a page to disk no longer requires making it read-only, which
allows us to write wired pages without causing all kinds of havoc.
- use a new PG_PAGEOUT flag to indicate that a page should be freed
on behalf of the pagedaemon when it's unlocked. this flag is very similar
to PG_RELEASED, but unlike PG_RELEASED, PG_PAGEOUT can be cleared if the
pageout fails due to eg. an indirect-block buffer being locked.
this allows us to remove the "version" field from struct vm_page,
and together with shrinking "loan_count" from 32 bits to 16,
struct vm_page is now 4 bytes smaller.
- no longer use PG_RELEASED for swap-backed pages. if the page is busy
because it's being paged out, we can't release the swap slot to be
reallocated until that write is complete, but unlike with vnodes we
don't keep a count of in-progress writes so there's no good way to
know when the write is done. instead, when we need to free a busy
swap-backed page, just sleep until we can get it busy ourselves.
- implement a fast-path for extending writes which allows us to avoid
zeroing new pages. this substantially reduces cpu usage.
- encapsulate the data used by the genfs code in a struct genfs_node,
which must be the first element of the filesystem-specific vnode data
for filesystems which use genfs_{get,put}pages().
- eliminate many of the UVM pagerops, since they aren't needed anymore
now that the pager "put" operation is a higher-level operation.
- enhance the genfs code to allow NFS to use the genfs_{get,put}pages
instead of a modified copy.
- clean up struct vnode by removing all the fields that used to be used by
the vfs_cluster.c code (which we don't use anymore with UBC).
- remove kmem_object and mb_object since they were useless.
instead of allocating pages to these objects, we now just allocate
pages with no object. such pages are mapped in the kernel until they
are freed, so we can use the mapping to find the page to free it.
this allows us to remove splvm() protection in several places.
The sum of all these changes improves write throughput on my
decstation 5000/200 to within 1% of the rate of NetBSD 1.5
and reduces the elapsed time for "make release" of a NetBSD 1.5
source tree on my 128MB pc to 10% less than a 1.5 kernel took.

When unmounting a file system, acquire the syncer_lock before vfs_busy'ing just before the dounmount() call. This is to avoid sleeping with the mountlist_slock held -- but we must acquire syncer_lock before vfs_busy because the syncer itself uses syncer_lock -> vfs_busy locking order.

add UBC memory-usage balancing. we track the number of pages in use for each of the basic types (anonymous data, executable image, cached files) and prevent the pagedaemon from reusing a given page if that would reduce the count of that type of page below a sysctl-setable minimum threshold. the thresholds are controlled via three new sysctl tunables: vm.anonmin, vm.vnodemin, and vm.vtextmin. these tunables are the percentages of pageable memory reserved for each usage, and we do not allow the sum of the minimums to be more than 95% so that there's always some memory that can be reused.

in vtruncbuf(), use a "synchronous freeing" flush to prevent a race between write i/os in a disk-based filesystem vs. the disk block being freed by a truncation, allocated to a new file, and written again with different data. if the disk driver reorders the requests and does the second i/o first, the old data will clobber the new, corrupting the new file.

Also, keep trying flushing buffers when the number of dirty buffers decreases (20 rounds may not be enouth for a very large buffer cache).

Also, keep trying flushing buffers when the number of dirty buffers decreases (20 rounds may not be enouth for a very large buffer cache). Using tsleep instead of delay gives a chance to others kernel threads to run, which is needed for raidframe.

Appears to fix: kern/9239, kern/10187, kern/9367. May also fix kern/10122.

Needed so those filesystems which went in via LKM have a chance to clean after themselves before unloading. This fixes random panics when LKM for filesystem using pools was loaded and unloaded several times. For each leaf filesystem, add appropriate vfs_done routine.

Move vinvalbuf's check for dirty blocks into ffs_fsync, to ensure that mode and ownership bits are flushed to disk before the vnode is reclaimed. The check, introduced in the softdep merge, assumes that if no blocks are dirty, no file data *or metadata* needs to be flushed to disk. This is true of ffs, but is not true of lfs, and may not be true of other filesystems. Tested by myself and Bill Squier <groo@cs.stevens-tech.edu>.

Give ufs_ihashget an extra argument: the flags passed to vget() for locking. This way we can avoid locking against ourselves when ufs_ihashget is called during the flushing of metadata. XXX Also, comment out a VOP_FSYNC call that I think is now unneeded, and put a diagnostic printf there to check if this still happens.

Merge changes in the trickle-sync and softdep code as done by Kirk McKusick in FreeBSD since the version that we based the branch on. Merging mostly done by Ethan Solomita <ethan@geocast.com>. Also, make sure the syncer thread/process isn't active when we're unmounting a filesystem. This could wreak havoc. XXX should be done on a per-mountpoint basis, but especially the softdep code would end up to be a big pile of vfs_busy() calls.

Add workaround hacks to enable the softdep code to call getnewvnode() when a filesystem is being unmounted. The problem is that the softdep code stored inode numbers in the worklist structures, and does not use vnodes. So VFS_VGET must be used to get a vnode during the final flush stages, and this can call getnewvnode(), resulting in a vfs_busy() + MNT_UNMOUNT hang. I've tried to make the softdep code use vnodes, but that's a pain, since it gets called at points were vnode ops are dangerous (i.e. interrupt context, and uncertainty whether a vnode is locked, etc). This is all icky stuff, but it does get things much closer to a working state..

Probable fix for PR7943: lookups fail spuriously over NFS. The problem was due to an interaction between the doomed unmounts done by amd and getnewvnode. I convinced myself that it's ok for getnewvnode() to do a sleeping vfs_busy(). Tested with multiple builds running while another process attempted to unmount /usr once a second.

Fix kern/7906: race between unmount and getnewvnode() mp->mnt_flags & MNT_MWAIT is replaced by mp->mnt_wcnt, and a new mount flag MNT_GONE is created (reusing the same bit). In insmntque(), add DIAGNOSTIC check to fail if the filesystem vnode is being moved to is in the process of being unmounted. getnewvnode() now protects the list of vnodes active on mp with vfs_busy()/vfs_unbusy(). To avoid generating spurious errors during a doomed unmount, change the "wait for unmount to finish" protocol between dounmount() and vfs_busy(). In vfs_busy(), instead of only sleeping once, sleep until either MNT_UNMOUNT is clear or MNT_GONE is set; also, maintain a count of waiters in mp->mnt_wcnt so that dounmount() knows when it's safe to free mp. tested by running a "while :; do mount /d1; umount -f /d1; done" loop against multiple find(1) processes.

vinvalbuf, called from vclean, could cause a locking-against-self deadlock in VOP_FSYNC() if the unreferenced vnode picked for reclamation happened to be stacked on top of a vnode the process already had locked. This could happen if the same filesystem was accessed both through a union mount and directly; it seemed to happen most frequently when the direct access was through NFS. Avoid this deadlock by changing vinvalbuf to pass a new FSYNC_RECLAIM flag bit to VOP_FSYNC() to indicate that a reclaim is in progress and only a `shallow' fsync is necessary. Do nothing in *_fsync() in umapfs, nullfs, and unionfs when FSYNC_RECLAIM is set; the underlying vnodes will shortly be released in *_reclaim and may be reclaimed (and fsync'ed) later.

In vfs_shutdown(), do the "sync and wait for it to finish" _before_ unmounting all of the file systems. If we encounter a condition where all of the dirty buffers could not flush, then don't unmount file systems, since it might be likely to wedge.

Allow multiple export requests for a filesystem, host pair if the flags and anon cred are the same. Should probably be handled better in the mountd, but this will do for now. Fixes PR 469, submitted Sept 1994 by a certain "Jason R. Thorpe".. ;-)

Add functions to set/reset the info about the publicly exported (WebNFS) filesystem. At first glance this should go into the NFS code, but all the other export code is here as well.

in vfs_shutdown(), print "syncing disks... " before dropping to spl0(), so that if the drop to spl0() causes another panic (e.g. because there's still some fatal hardware interrupt that's pending) we'll know that we dropped IPL to sync the disks.
