Port dholland's ufs_rename locking changes to netbsd-5.
[buhrow, ticket #1759]
Hello. More testing has revealed a minor misunderstanding between the
vnode API in -current and 5.x. The below patch, against NetBSD-5.1
sources, rolls all the accumulated patches into one patch set. With this
patch, I believe you can now run with WAPBL, softdep or traditional ufs
semantics with heavy file loads and avoid panics due to resource exhaustion
and/or tstile deadlocks. Testing has been done on I386, both uniprocessor
and multiprocessor, and on Sparc machines in uniprocessor mode, though I
think multiprocessor Sparc would be fine as well. Since these changes are
machine independent, I don't anticipate any issues on any platform. It is
my hope that modulo any final issues that come up in the final round of
testing I'm currently performing, these patches will be ready to be pulled
up into the NetBSD-5 branch.
Finally, I'd like to thank mouse@ and hannken@ for their help and
patience in helping me track down and test the final versions of these
patches. With their assistance, I'm confident these patches make NetBSD-5
a much more stable and robust operating environment in a variety of
setings.

* Remove PGO_RECLAIM during lfs_putpages()' call to genfs_putpages(), to avoid a live lock in the latter when reclaiming a vnode with dirty pages. * Add a new segment flag, SEGM_RECLAIM, to note when a segment is being written for vnode reclamation, and record which inode is being reclaimed, to aid in forensic debugging. * Add a new segment flag, SEGM_SINGLE, so that opportunistic writes can write a single segment's worth of blocks and then stop, rather than writing all the way up to the cleaner's reserved number of segments. * Add assert statements to check mutex ownership is the way it ought to be, mostly in lfs_putpages; fix problems uncovered by this. * Don't clear VU_DIROP until the inode actually makes its way to disk, avoiding a problem where dirop inodes could become separated (uncovered by a modified version of the "ckckp" forensic regression test). * Move the vfs_getopsbyname() call into lfs_writerd. Prepare code to make lfs_writerd notice when there are no more LFSs, and exit losing the reference, so that, in theory, the module can be unloaded. This code is not enabled, since it causes a crash on exit. * Set IN_MODIFIED on inodes flushed by lfs_flush_dirops. Really we only need to set IN_MODIFIED if we are going to write them again (e.g., to write pages); need to think about this more. Finally, several changes to help avoid "no clean segments" panics: * In lfs_bmapv, note when a vnode is loaded only to discover whether its blocks are live, so it can immediately be recycled. Since the cleaner will try to choose ~empty segments over full ones, this prevents the cleaner from (1) filling the vnode cache with junk, and (2) squeezing any unwritten writes to disk and running the fs out of segments. * Overestimate by half the amount of metadata that will be required to fill the clean segments. This will make the disk appear smaller, but should help avoid a "no clean segments" panic. * Rearrange lfs_writerd. In particular, lfs_writerd now pays attention to the number of clean segments available, and holds off writing until there is room.

strengthen the assertions about pages existing during block allocation, which were incorrectly relaxed last year. add some comments so that the intent of these is hopefully clearer. in ufs_balloc_range(), don't free pages or mark them dirty if allocating their backing store failed. this fixes PR 45369.

Pass the ufs_lookup_results pointer around instead of fetching it from the inode in the guts of ufs. Now, in VOPs where i_crap is used it is used (directly) only immediately on entry to the VOP call and then passed around by reference. Except for rename, which needs explicit sorting out. The code in ufs_wapbl_rename is unchanged in behavior but I'm increasingly inclined to think it's wrong.

Welcome to 5.99.53! Merge rmind-uvmplock branch: - Reorganize locking in UVM and provide extra serialisation for pmap(9). New lock order: [vmpage-owner-lock] -> pmap-lock. - Simplify locking in some pmap(9) modules by removing P->V locking. - Use lock object on vmobjlock (and thus vnode_t::v_interlock) to share the locks amongst UVM objects where necessary (tmpfs, layerfs, unionfs). - Rewrite and optimise x86 TLB shootdown code, make it simpler and cleaner. Add TLBSTATS option for x86 to collect statistics about TLB shootdowns. - Unify /dev/mem et al in MI code and provide required locking (removes kernel-lock on some ports). Also, avoid cache-aliasing issues. Thanks to Andrew Doran and Joerg Sonnenberger, as their initial patches formed the core changes of this branch.

Remove the special refcount behavior (adding an extra reference to the parent dir) associated with SAVESTART in relookup(). Check all call sites to make sure that SAVESTART wasn't set while calling relookup(); if it was, adjust the refcount behavior. Remove related references to SAVESTART. The only code that was reaching the extra ref was msdosfs_rename, where the refcount behavior was already fairly broken and/or gross; repair it. Add a dummy 4th argument to relookup to make sure code that hasn't been inspected won't compile. (This will go away next time the relookup semantics change, which they will.)

It's not a good idea for device drivers to modify b_flags, as they don't need to understand the locking around that field. Instead of setting B_ERROR, set b_error instead. b_error is 'owned' by whoever completes the I/O request.

Install a new sysctl, vfs.lfs.ignore_lazy_sync, which causes LFS to ignore the "smooth" syncer, as if vfs.sync.*delay = 0, but only for LFS. The default is "on", i.e., ignore lazy sync. Reduce the amount of polling/busy-waiting done by lfs_putpages(). To accomplish this, copied genfs_putpages() and modified it to indicate which page it was that caused it to return with EDEADLK. fsync()/fdatasync() should no longer ever fail with EAGAIN, and should not consume huge quantities of cpu. Also, try to make dirops less likely to be written as the result of a VOP_PUTPAGES(), while ensuring that they are written regularly.

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).

a smorgasbord of improvements to vnode locking and path lookup: - LOCKPARENT is no longer relevant for lookup(), relookup() or VOP_LOOKUP(). these now always return the parent vnode locked. namei() works as before. lookup() and various other paths no longer acquire vnode locks in the wrong order via vrele(). fixes PR 32535. as a nice side effect, path lookup is also up to 25% faster. - the above allows us to get rid of PDIRUNLOCK. - also get rid of WANTPARENT (just use LOCKPARENT and unlock it). - remove an assumption in layer_node_find() that all file systems implement a recursive VOP_LOCK() (unionfs doesn't). - require that all file systems supply vfs_vptofh and vfs_fhtovp routines. fill in eopnotsupp() for file systems that don't support being exported and remove the checks for NULL. (layerfs calls these without checking.) - in union_lookup1(), don't change refcounts in the ISDOTDOT case, just adjust which vnode is locked. fixes PR 33374. - apply fixes for ufs_rename() from ufs_vnops.c rev. 1.61 to ext2fs_rename().

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.

Don't remark a locked inode with IN_MODIFIED after writing it to disk, if we ourselves hold the lock. This prevents e.g. mknod from hanging indefinitely. Also, always use the return value from VOP_ISLOCKED to determine whether we hold the lock or someone else does, rather than looking into the lock structure ourselves.

Changes to help the roll-forward agent, to wit: * Mark being-deleted files in the Ifile so we can finish deleting them at fs mount time. * Flag the Ifile with "cleaner must clean" when writers are waiting for the cleaner, rather than relying solely on the cleaner's estimation of whether it should clean or not. * Note partial segments written by a user agent (in particular, fsck_lfs) so that repeated rolls forward don't interfere with one another. * Add a new fcntl, LFCNPASS, that allows the log to wrap exactly once, for better testing of the validity of checkpoints. * Keep track of the on-disk nlink count when cleaning, so that we don't partially complete directory operations while cleaning. * Ensure that every single Ifile inode write represents a consistent view of the filesystem. In particular, the accounting for the segment we are writing the inode into must be correct, and the accounting for the segment that inode used to reside in must be correct. Rather than just rewriting the inode if we wrote it wrong, rewrite the necessary ifile blocks before writing the inode so we never write it wrong. * Don't unmark any VDIROP vnodes if we haven't written them to disk, avoiding yet another problem with the "wait for the cleaner" error return from lfs_putpages(). Also, move the last callback to an aiodone call, so we no longer do any memory management from interrupt context.

Fix size confusion with lfs_fhandle - and as it now turns out to be the same as the lfs compat_30_fhandle, g/c the latter. Add an alias for the LFCNIFILEFH fcntl, so that binaries compiled in the meantime (with too large lfs_fhandle) continue to work. This makes vfs_cleanerd work again after the kernel checks filehandle size more strictly (problem reported by Kurt Schreiner on current-users).

Change LFCNWRAP{STOP,GO} to make them more suitable for snapshotting; in
particular, the caller can now choose whether to wait for the condition
to be met, and if the caller of LFCNWRAPSTOP dies or otherwise closes
the descriptor, the filesystem is started again. Updated the ckckp
regression test to use the new semantics.
dump_lfs(8) now uses the fcntls to implement LFS-style snapshotting through
the -X flag, addressing PR#33457 albeit not using fss(4). Fixed a couple
other problems with dump_lfs that manifested themselves during testing.

Make sure that we write all the pages on vnodes that are being flushed, even if we don't think there's room; drain v_numoutput before lfs_vflush() completes. Also, don't allow a vnode that is in the process of being cleaned to be chosen by getnewvnode(); this avoids a segment accounting panic in the case that a large number of inodes are fed to lfs_markv() all at once.

The default value used for existing filesystems is the same as the previous implicit value of (lfs_minfreeseg / 2 + 1), modulo some sanity checking. Count pending dirops on a per-filesystem basis, since once we start writing them we can't stop until we're done. This seems to help stave off the "no clean segments" panic in the case of filling the filesystem with directories and small files (e.g. simultaneously unpacking more copies of pkgsrc than will fit).

This allows for automated checkpoint vailidity scanning, and could be used (in conjunction with the existing LFCNREWIND) for e.g. snapshot dumps as well. Include a regression test that does such scanning. When writing the Ifile, loop through the dirty block list three times to make sure that the checkpoint is always consistent (the first and second times the Ifile blocks can cross a segment boundary; not so the third time unless the segments are very small). Discovered by using the aforementioned regression test.

Fixes to address the "vinvalbuf: dirty blocks" panic that can occur when many inodes are cleaned at once. Make sure that we write all the pages on vnodes that are being flushed, even if we don't think there's room; drain v_numoutput before lfs_vflush() completes. Also, don't allow a vnode that is in the process of being cleaned to be chosen by getnewvnode(); this avoids a segment accounting panic in the case that a large number of inodes are fed to lfs_markv() all at once.

Introduce another per-filesystem parameter, lfs_resvseg, to separate the notion of "how many segments are reserved for the cleaner" from that of "how many segments are not counted in lfs_bfree". The default value used for existing filesystems is the same as the previous implicit value of (lfs_minfreeseg / 2 + 1), modulo some sanity checking. Count pending dirops on a per-filesystem basis, since once we start writing them we can't stop until we're done. This seems to help stave off the "no clean segments" panic in the case of filling the filesystem with directories and small files (e.g. simultaneously unpacking more copies of pkgsrc than will fit).

Introduce two fcntl calls that freeze the filesystem right at the point where segment 0 is being considered for writing. This allows for automated checkpoint vailidity scanning, and could be used (in conjunction with the existing LFCNREWIND) for e.g. snapshot dumps as well. Include a regression test that does such scanning. When writing the Ifile, loop through the dirty block list three times to make sure that the checkpoint is always consistent (the first and second times the Ifile blocks can cross a segment boundary; not so the third time unless the segments are very small). Discovered by using the aforementioned regression test.

Improvements to LFS's paging mechanism, to wit: * Acknowledge that sometimes there are more dirty pages to be written to disk than clean segments. When we reach the danger line, lfs_gop_write() now returns EAGAIN. The caller of VOP_PUTPAGES(), if it holds the segment lock, drops it and waits for the cleaner to make room before continuing. * Note and avoid a three-way deadlock in lfs_putpages (a writer holding a page busy blocks on the cleaner while the cleaner blocks on the segment lock while lfs_putpages blocks on the page).

Various minor LFS improvements.
Kernel:
* Note when lfs_putpages(9) thinks it is not going to be writing any
pages before calling genfs_putpages(9). This prevents a situation in
which blocks can be queued for writing without a segment header.
* Correct computation of NRESERVE(), though it is still a gross
overestimate in most cases. Note that if NRESERVE() is too high, it
may be impossible to create files on the filesystem. We catch this
case on filesystem mount and refuse to mount r/w.
* Allow filesystems to be mounted whose block size is == MAXBSIZE.
* Somewhere along the line, ufs_bmaparray(9) started mangling UNWRITTEN
entries in indirect blocks again, triggering a failed assertion "daddr
<= LFS_MAX_DADDR". Explicitly convert to and from int32_t to correct
this. Should fix PR #29045.
* Add a high-water mark for the number of dirty pages any given LFS can
hold before triggering a flush. This is settable by sysctl, but off
(zero) by default.
* Be more careful about the MAX_BYTES and MAX_BUFS computations so we
shouldn't see "please increase to at least zero" messages.
* Note that VBLK and VCHR vnodes can have nonzero values in di_db[0]
even though their v_size == 0. Don't panic when we see this.
Fixes PR #26680.
* Change lfs_bfree to a signed quantity. The manner in which it is
processed before being passed to the cleaner means that sometimes it
may drop below zero, and the cleaner must be aware of this.
* Never report bfree < 0 (or higher than lfs_dsize) through
lfs_statfs(9). This prevents df(1) from ever telling us that our full
filesystems have 16TB free.
* Account space allocated through lfs_balloc(9) that does not have
associated buffer headers, so that the pagedaemon doesn't run us out
of segments.
* Return ENOSPC from lfs_balloc(9) when bfree drops to zero.
* Address a deadlock in lfs_bmapv/lfs_markv when the filesystem is being
unmounted. Because vfs_busy() is a shared lock, and
lfs_bmapv/lfs_markv mark the filesystem vfs_busy(), the cleaner can be
holding the lock that umount() is blocking on, then try to vfs_busy()
again in getnewvnode().
cleaner:
* Adapt lfs_cleanerd to use the fcntl call to get the Ifile filehandle,
so it need not be in the namespace.
* Make lfs_cleanerd be more careful when there are very few available
segments.
* Make lfs_cleanerd less verbose when the filesystem is unmounted.
newfs_lfs, fsck_lfs, and regression:
* Extend the lfs library from fsck_lfs(8) so that it can be used with a
not-yet-existent LFS. Make newfs_lfs(8) use this library, so it can
create LFSs whose Ifile is larger than one segment. Addresses PR #11110.
* Make newfs_lfs(8) use strsuftoi64() for its arguments, a la newfs(8).
* Make fsck_lfs(8) respect the "file system is clean" flag.
* Don't let fsck_lfs(8) think it has dirty blocks when invoked with the
-n flag.
* Remove the Ifile from the filesystem namespace. The cleaner now uses
a fcntl call on the root inode to find the Ifile filehandle. (As a
side-effect, addresses PR #29144.)

Keep per-inode, per-fs, and subsystem-wide counts of blocks allocated through lfs_balloc(), and use that to estimate the number of dirty pages belonging to LFS (subsystem or filesystem). This is almost certainly wrong for the case of a large mmap()ed region, but the accounting is tighter than what we had before, and performs much better in the typical case of pages dirtied through write().

Pull up revision 1.138 (requested by perseant in ticket #74): Make LFS dirops get their vnode first, before incrementing the dirop count, to prevent a deadlock trying to call VOP_PUTPAGES() on a VDIROP vnode. This can happen when a stacked filesystem is mounted on top of an LFS: an LFS dirop needs to get a vnode, which is available from the upper layer. The corresponding lower layer vnode, however, is VDIROP, so the upper layer can't be cleaned out since its VOP_PUTPAGES() is passed through to the lower layer, which waits for dirops to drain before it can proceed. Deadlock. Tweak ufs_makeinode() and ufs_mkdir() to pass the a_vpp argument through to VOP_VALLOC(). Partially addresses PR # 26043, though it probably does not completely fix the problem described there.

Various minor LFS improvements: * Note when lfs_putpages(9) thinks it is not going to be writing any pages before calling genfs_putpages(9). This prevents a situation in which blocks can be queued for writing without a segment header. * Correct computation of NRESERVE(), though it is still a gross overestimate in most cases. Note that if NRESERVE() is too high, it may be impossible to create files on the filesystem. We catch this case on filesystem mount and refuse to mount r/w. * Allow filesystems to be mounted whose block size is == MAXBSIZE. * Somewhere along the line, ufs_bmaparray(9) started mangling UNWRITTEN entries in indirect blocks again, triggering a failed assertion "daddr <= LFS_MAX_DADDR". Explicitly convert to and from int32_t to correct this. * Add a high-water mark for the number of dirty pages any given LFS can hold before triggering a flush. This is settable by sysctl, but off (zero) by default. * Be more careful about the MAX_BYTES and MAX_BUFS computations so we shouldn't see "please increase to at least zero" messages. * Note that VBLK and VCHR vnodes can have nonzero values in di_db[0] even though their v_size == 0. Don't panic when we see this. * Change lfs_bfree to a signed quantity. The manner in which it is processed before being passed to the cleaner means that sometimes it may drop below zero, and the cleaner must be aware of this. * Never report bfree < 0 (or higher than lfs_dsize) through lfs_statvfs(9). This prevents df(1) from ever telling us that our full filesystems have 16TB free. * Account space allocated through lfs_balloc(9) that does not have associated buffer headers, so that the pagedaemon doesn't run us out of segments. * Return ENOSPC from lfs_balloc(9) when bfree drops to zero. * Address a deadlock in lfs_bmapv/lfs_markv when the filesystem is being unmounted. Because vfs_busy() is a shared lock, and lfs_bmapv/lfs_markv mark the filesystem vfs_busy(), the cleaner can be holding the lock that umount() is blocking on, then try to vfs_busy() again in getnewvnode().

fix a bug of lfs.
genfs_getpages() can read in more blocks than it should due to faked filesize
of lfs_gop_size(). it's a security problem and it makes gcc3 "internal error"
to fix this,
- in genfs_getpages(), always calculate diskeof and memeof separately
so that filesystems (in this case, lfs) can use different strategies
for them.
- introduce GOP_SIZE_MEM flag and use it to request in-core filesize.
(it was an intention of GOP_SIZE_READ,
but after the above change _READ is not a straightforward name)
after this, no one uses GOP_SIZE_{READ,WRITE} anymore but leave them for now.

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.

Make LFS work better (though still not "well") as an NFS-exported filesystem (and other things that needed to be fixed before the tests would complete), to wit: * Include the fs ident in the filehandle; improve stale filehandle checks. * Change definition of blksize() to use the on-dinode size instead of the inode's i_size, so that fsck_lfs will work properly again. * Use b_interlock in lfs_vtruncbuf. * Postpone dirop reclamation until after the seglock has been released, so that lfs_truncate is not called with the segment lock held. * Don't loop in lfs_fsync(), just write everything and wait. * Be more careful about the interlock/uobjlock in lfs_putpages: when we lose this lock, we have to resynchronize dirtiness of pages in each block. * Be sure to always write indirect blocks and update metadata in lfs_putpages; fixes a bug that caused blocks to be accounted to the wrong segment.

Add an lfs_strategy() that checks to make sure we're not trying to read where the cleaner is trying to write, instead of tying up the "live" buffers (or pages). Fix a bug in the LFS_UBC case where oversized buffers would not be checksummed correctly, causing uncleanable segments. Make sure that wakeup(fs->lfs_iocount) is done if fs->lfs_iocount is 1 as well as 0, since we wait in some places for it to drop to 1. Activate all pages that make it into lfs_gop_write without the segment lock held, since they must have been dirtied very recently, even if PG_DELWRI is not set.

Add code to UBCify LFS. This is still behind "#ifdef LFS_UBC" for now (there are still some details to work out) but expect that to go away soon. To support these basic changes (creation of lfs_putpages, lfs_gop_write, mods to lfs_balloc) several other changes were made, to wit: * Create a writer daemon kernel thread whose purpose is to handle page writes for the pagedaemon, but which also takes over some of the functions of lfs_check(). This thread is started the first time an LFS is mounted. * Add a "flags" parameter to GOP_SIZE. Current values are GOP_SIZE_READ, meaning that the call should return the size of the in-core version of the file, and GOP_SIZE_WRITE, meaning that it should return the on-disk size. One of GOP_SIZE_READ or GOP_SIZE_WRITE must be specified. * Instead of using malloc(...M_WAITOK) for everything, reserve enough resources to get by and use malloc(...M_NOWAIT), using the reserves if necessary. Use the pool subsystem for structures small enough that this is feasible. This also obsoletes LFS_THROTTLE. And a few that are not strictly necessary: * Moves the LFS inode extensions off onto a separately allocated structure; getting closer to LFS as an LKM. "Welcome to 1.6O." * Unified GOP_ALLOC between FFS and LFS. * Update LFS copyright headers to correct values. * Actually cast to unsigned in lfs_shellsort, like the comment says. * Keep track of which segments were empty before the previous checkpoint; any segments that pass two checkpoints both dirty and empty can be summarily cleaned. Do this. Right now lfs_segclean still works, but this should be turned into an effectless compatibility syscall.

Curproc->curlwp renaming. Change uses of "curproc->l_proc" back to "curproc", which is more like the original use. Bare uses of "curproc" are now "curlwp". "curproc" is now #defined in proc.h as ((curlwp) ? (curlwp)->l_proc) : NULL) so that it is always safe to reference curproc (*de*referencing curproc is another story, but that's always been true).

Pull up revision 1.65 (requested by perseant in ticket #325): For synchronous writes, keep separate i/o counters for each write, so processes don't have to wait for one another to finish (e.g., nfsd seems to be a little happier now, though I haven't measured the difference). Synchronous checkpoints, however, must always wait for all i/o to finish. Take the contents of the callback functions and have them run in thread context instead (aiodoned thread). lfs_iocount no longer has to be protected in splbio(), and quite a bit less of the segment construction loop needs to be in splbio() as well. If lfs_markv is handed a block that is not the correct size according to the inode, refuse to process it. (Formerly it was extended to the "correct" size.) This is possibly more prone to deadlock, but less prone to corruption. lfs_segclean now outright refuses to clean segments that appear to have live bytes in them. Again this may be more prone to deadlock but avoids corruption. Replace ufsspec_close and ufsfifo_close with LFS equivalents; this means that no UFS functions need to know about LFS_ITIMES any more. Remove the reference from ufs/inode.h. Tested on i386, test-compiled on alpha.

Phase one of my three-phase plan to make LFS play nice with UBC, and bug-fixes I found while making sure there weren't any new ones. * Make the write clusters keep track of the buffers whose blocks they contain. This should make it possible to (1) write clusters using a page mapping instead of malloc, if desired, and (2) schedule blocks for rewriting (somewhere else) if a write error occurs. Code is present to use pagemove() to construct the clusters but that is untested and will go away anyway in favor of page mapping. * DEBUG now keeps a log of Ifile writes, so that any lingering instances of the "dirty bufs" problem can be properly debugged. * Keep track of whether the Ifile has been dirtied by various routines that can be called by lfs_segwrite, and loop on that until it is clean, for a checkpoint. Checkpoints need to be squeaky clean. * Warn the user (once) if the Ifile grows larger than is reasonable for their buffer cache. Both lfs_mountfs and lfs_unmount check since the Ifile can grow. * If an inode is not found in a disk block, try rereading the block, under the assumption that the block was copied to a cluster and then freed. * Protect WRITEINPROG() with splbio() to fix a hang in lfs_update.

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.

Merge the short-lived perseant-lfsv2 branch into the trunk. Kernels and tools understand both v1 and v2 filesystems; newfs_lfs generates v2 by default. Changes for the v2 layout include: - Segments of non-PO2 size and arbitrary block offset, so these can be matched to convenient physical characteristics of the partition (e.g., stripe or track size and offset). - Address by fragment instead of by disk sector, paving the way for non-512-byte-sector devices. In theory fragments can be as large as you like, though in reality they must be smaller than MAXBSIZE in size. - Use serial number and filesystem identifier to ensure that roll-forward doesn't get old data and think it's new. Roll-forward is enabled for v2 filesystems, though not for v1 filesystems by default. - The inode free list is now a tailq, paving the way for undelete (undelete is not yet implemented, but can be without further non-backwards-compatible changes to disk structures). - Inode atime information is kept in the Ifile, instead of on the inode; that is, the inode is never written *just* because atime was changed. Because of this the inodes remain near the file data on the disk, rather than wandering all over as the disk is read repeatedly. This speeds up repeated reads by a small but noticeable amount. Other changes of note include: - The ifile written by newfs_lfs can now be of arbitrary length, it is no longer restricted to a single indirect block. - Fixed an old bug where ctime was changed every time a vnode was created. I need to look more closely to make sure that the times are only updated during write(2) and friends, not after-the-fact during a segment write, and certainly not by the cleaner.

Change disk addressing unit to be the fragment, instead of the disk sector. All quantities in the superblock, inodes, indirect blocks, etc. refer now to this abstract unit (called "fsb" as it is in FFS) instead of disk sectors; as a consequence segment summary blocks have to be multiples of a fragment in size. In v1 filesystems, compatibility code ensures that 1 fsb == 1 sector, regardless of fragment size. Fragments can now range in size between 512 and 32k; in the event that LFS_LABELPAD (8k) is smaller than the disk address unit size, an extra proto-superblock is kept at 8k from the beginning of the disk, to be used *only* to locate the real superblocks. (Not all of the userland knows about this yet.) Almost all of this was done not by me, but by joff.

Correct accounting of lfs_avail, locked_queue_count, and locked_queue_bytes. (PR #11468). In the case of fragment allocation, check to see if enough space is available before extending a fragment already scheduled for writing. The locked_queue_* variables indicate the number of buffer headers and bytes, respectively, that are unavailable to getnewbuf() because they are locked up waiting for LFS to flush them; make sure that that is actually what we're counting, i.e., never count malloced buffers, and always use b_bufsize instead of b_bcount. If DEBUG is defined, the periodic calls to lfs_countlocked will now complain if either counter is incorrect. (In the future lfs_countlocked will not need to be called at all if DEBUG is not defined.)

Also, during dirops, give the directory vnode an extra reference in SET_DIROP, to ensure its continued existence during SET_ENDOP, preventing a possible NULL-dereference there.

Various bug-fixes to LFS, to wit: Kernel: * Add runtime quantity lfs_ravail, the number of disk-blocks reserved for writing. Writes to the filesystem first reserve a maximum amount of blocks before their write is allowed to proceed; after the blocks are allocated the reserved total is reduced by a corresponding amount. If the lfs_reserve function cannot immediately reserve the requested number of blocks, the inode is unlocked, and the thread sleeps until the cleaner has made enough space available for the blocks to be reserved. In this way large files can be written to the filesystem (or, smaller files can be written to a nearly-full but thoroughly clean filesystem) and the cleaner can still function properly. * Remove explicit switching on dlfs_minfreeseg from the kernel code; it is now merely a fs-creation parameter used to compute dlfs_avail and dlfs_bfree (and used by fsck_lfs(8) to check their accuracy). Its former role is better assumed by a properly computed dlfs_avail. * Bounds-check inode numbers submitted through lfs_bmapv and lfs_markv. This prevents a panic, but, if the cleaner is feeding the filesystem the wrong data, you are still in a world of hurt. * Cleanup: remove explicit references of DEV_BSIZE in favor of btodb()/dbtob(). lfs_cleanerd: * Make -n mean "send N segments' blocks through a single call to lfs_markv". Previously it had meant "clean N segments though N calls to lfs_markv, before looking again to see if more need to be cleaned". The new behavior gives better packing of direct data on disk with as little metadata as possible, largely alleviating the problem that the cleaner can consume more disk through inefficient use of metadata than it frees by moving dirty data away from clean "holes" to produce entirely clean segments. * Make -b mean "read as many segments as necessary to write N segments of dirty data back to disk", rather than its former meaning of "read as many segments as necessary to free N segments worth of space". The new meaning, combined with the new -n behavior described above, further aids in cleaning storage efficiency as entire segments can be written at once, using as few blocks as possible for segment summaries and inode blocks. * Make the cleaner take note of segments which could not be cleaned due to error, and not attempt to clean them until they are entirely free of dirty blocks. This prevents the case in which a cleanerd running with -n 1 and without -b (formerly the default) would spin trying repeatedly to clean a corrupt segment, while the remaining space filled and deadlocked the filesystem. * Update the lfs_cleanerd manual page to describe all the options, including the changes mentioned here (in particular, the -b and -n flags were previously undocumented). fsck_lfs: * Check, and optionally fix, lfs_avail (to an exact figure) and lfs_bfree (within a margin of error) in pass 5. newfs_lfs: * Reduce the default dlfs_minfreeseg to 1/20 of the total segments. * Add a warning if the sgs disklabel field is 16 (the default for FFS' cpg, but not usually desirable for LFS' sgs: 5--8 is a better range). * Change the calculation of lfs_avail and lfs_bfree, corresponding to the kernel changes mentioned above. mount_lfs: * Add -N and -b options to pass corresponding -n and -b options to lfs_cleanerd. * Default to calling lfs_cleanerd with "-b -n 4". [All of these changes were largely tested in the 1.5 branch, with the idea that they (along with previous un-pulled-up work) could be applied to the branch while it was still in ALPHA2; however my test system has experienced corruption on another filesystem (/dev/console has gone missing :^), and, while I believe this unrelated to the LFS changes, I cannot with good conscience request that the changes be pulled up.]

Clean up accounting of lfs_uinodes (dirty but unwritten inodes). Make lfs_uinodes a signed quantity for debugging purposes, and set it to zero as fs mount time. Enclose setting/clearing of the dirty flags (IN_MODIFIED, IN_ACCESSED, IN_CLEANING) in macros, and use those macros everywhere. Make LFS_ITIMES use these macros; updated the ITIMES macro in inode.h to know about this. Make ufs_getattr use ITIMES instead of FFS_ITIMES.

Fixes associated with filling an LFS: Change the space computation to appear to change the size of the *disk* rather than the *bytes used* when more segment summaries and inode blocks are written. Try to estimate the amount of space that these will take up when more files are written, so the disk size doesn't change too much. Regularize error returns from lfs_valloc, lfs_balloc, lfs_truncate: they now fail entirely, rather than succeeding half-way and leaving the fs in an inconsistent state. Rewrite lfs_truncate, mostly stealing from ffs_truncate. The old lfs_truncate had difficulty truncating a large file to a non-zero size (indirect blocks were not handled appropriately). Unmark VDIROP on fvp after ufs_remove, ufs_rmdir, so these can be reclaimed immediately: this vnode would not be written to disk again anyway if the removal succeeded, and if it failed, no directory operation occurred. ufs_makeinode and ufs_mkdir now remove IN_ADIROP on error.

Change the sementics of the last parameter from a boolean ("waitfor") to
a set of flags ("flags"). Two flags are defined, UPDATE_WAIT and
UPDATE_DIROP.
Under the old semantics, VOP_UPDATE would block if waitfor were set,
under the assumption that directory operations should be done
synchronously. At least LFS and FFS+softdep do not make this
assumption; FFS+softdep got around the problem by enclosing all relevant
calls to VOP_UPDATE in a "if(!DOINGSOFTDEP(vp))", while LFS simply
ignored waitfor, one of the reasons why NFS-serving an LFS filesystem
did not work properly.
Under the new semantics, the UPDATE_DIROP flag is a hint to the
fs-specific update routine that the call comes from a dirop routine, and
should be wait for, or not, accordingly.
Closes PR#8996.

Address ufs_hashlock/ufs_ihashins protocol bug, discovered while doing a post-mortem of a production machine. Also, take the active dirop count off of the fs and make it global (since it is measuring a global resource) and tie the threshold value LFS_MAXDIROP to desiredvnodes.

Better fix for PR# 8577: before setting dirops, check for cross-device rename and error out. This avoids possible problems with attempting rename between two LFSs.

Make changes that will allow an LFS filesystem to be used as the root filesystem. In particular, - Fix mknod deadlock, described in PR 8172. - Enable lfs_mountroot. - Make lfs_writevnodes treat filesystems mounted on lfs device nodes properly, by flushing that device rather than trying to add blocks to the device inode. This, in combination with lfs boot blocks, will allow operation of an all-lfs system.

Rudimentary support for LFS under UBC:
- LFS-specific VOP_BALLOC and VOP_PUTPAGES vnode ops.
- getblk VREG panic #ifdef'd out (can be reinstated when Ifile is
internalized and Ifile can be made another type from VREG)
- interface to VOP_PUTPAGES changed to pass all pager flags, not
just sync. FS putpages routines must know about the pager flags.
- new LFS magic disk address, -2 ("unwritten"), meaning accounted for
but not assigned to a fixed disk location (since LFS does these two
things separately, and the previous accounting method using buffer
headers no longer will work). Changed references to (foo == (daddr_t)-1)
to (foo < 0). Since disk drivers reject all addresses < 0, this should
not present a problem for other FSs.

Pull-up of changes made to the trunk on Sunday [1.25->1.26], to wit: Take out the `#ifdef USE_UFSHASH'; use ufs_hashlock to lock the inode free list instead of free_lock. Fix inode reporting in lfs_statfs (the meaning of f_files and f_ffree was reversed). Fix "lfs_ifind: dinode xxx not found" panic. When inodes were freed, then immediately reloaded, their dinodes were located in an inode block which was not on disk at the advertized location, nor in the cache (although it would be flushed to disk next segment write). Fix this by using getblk() instead of lfs_newbuf() for inode blocks. Better checking for held inode locks in lfs_fastvget, for a number of error conditions. Also change the default setting of lfs_clean_vnhead to 0, which seems to make the locking problems go away (although this is difficult to test as I can't reliably reproduce them). Make sure that the wakeup occurs for vnodes that lfs_update might be sleeping on (nodes which are not marked IN_MODIFIED/IN_CLEANING, but which have dirty buffers), by marking them with the appropriate flag if dirtybuffers were added while the write was in progress. Fix block counting during file truncation, if not truncating to zero. Disallow threshold-initiated cache flush when dirops are active. Also, make SET_ENDOP use lfs_check instead of inlining most of it. Improve the debugging printfs in the cleaner syscalls (in particular, make it obvious that they're coming from lfs). Check the superblock version field, and refuse to mount the filesystem if the version number is higher than we know about. This allows, e.g., changes in the format of the ifile, segment size restrictions and boundaries, etc., which would not affect existing fields in the superblock, but which would drastically affect the filesystem, to be smoothly integrated at a later date.

Since dirop vnodes can't be flushed, they hold a reference until their dirop is completely written to disk. This means that ordinary calls to ufs vnops which would ordinarily call VOP_INACTIVE through vrele/vput, don't. This patch detects that condition after such vnops have been run, and calls VOP_INACTIVE if it would ordinarily have been called by the ufs call.

New sources should leave the LFS in a more-or-less working state. Changes include: - DIROP segregation is enabled, and greater care is taken to make sure that a checkpoint completes. Fsck is not needed to remount the filesystem. - Several checks to make sure that the LFS subsystem does not overuse various resources (memory, in particular). - The cleaner routines, lfs_markv in particular, are completely rewritten. A buffer overflow is removed. Greater care is taken to ensure that inodes come from where lfs_cleanerd say they come from (so we know nothing has changed since lfs_bmapv was called). - Fragment allocation is fixed, so that writes beyond end-of-file do the right thing.

Add support for ext2fs, this needed a few modifications to ufs/ufs/inode.h:
- added an "union inode_ext" to struct inode, for the per-fs extentions.
For now only ext2fs uses it.
- i_din is now an union:
union {
struct dinode ffs_din; /* 128 bytes of the on-disk dinode. */
struct ext2fs_dinode e2fs_din; /* 128 bytes of the on-disk dinode. */
} i_din
Added a lot of #define i_ffs_* and i_e2fs_* to access the fields.
- Added two macros: FFS_ITIMES and EXT2FS_ITIMES. ITIMES calls the rigth
macro, depending on the time of the inode. ITIMES is used where necessary,
FFS_ITIMES and EXT2FS_ITIMES in other places.
