Adapt dholland@'s fix to ufs_rename to fix PR kern/43582. Address several other MP locking issues discovered during the course of investigating the same problem. Removed extraneous vn_lock() calls on the Ifile, since the Ifile writes are controlled by the segment lock. Fix PR kern/45982 by deemphasizing the estimate of how much metadata will fill the empty space on disk when the disk is nearly empty (t_renamerace crates a lot of inode blocks on a tiny empty disk).

* 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.

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.

Instead of having lfs muck directly about with vnode free lists,
introduce vrele2(), which allows to release vnodes the way lfs
sometimes wants it:
+ without calling inactive
+ inserting the vnode at the head of the freelist (this is a very
questionable optimization that isn't even enabled by default,
but I went along with the same semantics for now)

Implementation of per-CPU work-queues support for workqueue(9) interface. WQ_PERCPU flag for workqueue and additional argument for workqueue_enqueue() to assign a CPU might be used. Notes: - For now, the list is used for workqueue_queue, which is non-optimal, and will be changed with array, where index would be CPU ID. - The data structures should be changed to be cache-friendly.

Using POOL_INIT here makes no sense, since file systems always have an init method. So get rid of it and #ifdef _LKM and just always init in the init method. Give malloc types the same treatment. Makes file systems nicer to work with in linksetless environments and fixes a few LKM discrepancies.

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.

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.

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.

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.

fix a simonb-timecounters regression. the precision of getnanotime() is not suitable for file timestamps. esp. when it's nfs-exported. - introduce vfs_timestamp(). (the name is from freebsd. currently merely a wrapper of nanotime()) - for ufs-like filesystems, use it rather than getnanotime(). XXX check other filesystems.

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.

Pull up following revision(s) (requested by perseant in ticket #1327): sys/ufs/lfs/lfs_segment.c: revision 1.175 Regression test improvements: Move the stop for LFCNWRAPSTOP to the point at which writing at segment 0 is really about to commence, since this is what the test expects (and incidentally what a snapshotting utility wants as well). More correctly reconstruct the on-disk state at every checkpoint, rather than relying on the entire state at the point of wrapping to be accurate (that is only true the first time we wrap). Add a "make abort" target to make rerunning the test more convenient when it has failed and we're done analyzing the failure.

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.

Regression test improvements: Move the stop for LFCNWRAPSTOP to the point at which writing at segment 0 is really about to commence, since this is what the test expects (and incidentally what a snapshotting utility wants as well). More correctly reconstruct the on-disk state at every checkpoint, rather than relying on the entire state at the point of wrapping to be accurate (that is only true the first time we wrap). Add a "make abort" target to make rerunning the test more convenient when it has failed and we're done analyzing the failure.

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().

Keep track of the highest block held by an LFS inode, so that we can be assured that the last byte of a file is always allocated. Previously a file extension could cause the filesystem to be flushed, writing an inconsistent inode to disk. Although this condition would be corrected the next time blocks were written to disk, an intervening crash would leave the filesystem in an inconsistent state, leaving fsck_lfs to complain of an inode "partially truncated".

Straighten out the maze of ifdefs. Instead, consolidate all the debugging stuff under '#ifdef DEBUG', and use sysctl knobs to turn on/off particular parts of the debugging reporting (if DEBUG is enabled). Re-enable the LFS statistics in sysctl, while I'm there. A bit of a rototill.

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().

Add a new flag, IN_MODIFY. This is like IN_UPDATE|IN_CHANGE, but unlike setting those flags, it does not cause the inode to be written in the periodic sync. This is used for writes to special files (devices and named pipes) and FIFOs. Do not preemptively sync updates to access times and modification times. They are now updated in the inode only opportunistically, or when the file or device is closed. (Really, it should be delayed beyond close, but this is enough to help substantially with device nodes.) And the most amusing part: Trickle sync was broken on both FFS and ext2fs, in different ways. In FFS, the periodic call to VFS_SYNC(MNT_LAZY) was still causing all file data to be synced. In ext2fs, it was causing the metadata to *not* be synced. We now only call VOP_UPDATE() on the node if we're doing MNT_LAZY. I've confirmed that we do in fact trickle correctly now.

The checkpoint loop always used (multiples of) lfs_sepb as the number of segments to mark. However, this may be much more than lfs_nseg. Originally this wasn't a big problem, since only the structures in the diskblock were changed, but nowadays there's a mirror of the segflags in the in-core superblock. This problem caused the code to walk way past the end of that allocated area, causing memory corruption in other kernel structures. So, use lfs_nseg as the maximum, as it should be. While here, simplify the loop; it had become an obfuscated piece of code overtime.

Don't break out of Ifile-writing loop in lfs_segwrite until nothing is left. Note however that blocks can be added to the Ifile even when the segment block is held because of inodes' atime. Do not panic with "dirty blocks" if these blocks are present.

Add simple_lock protection for lfs_seglock and lfs_subsys_pages; these will be expanded to cover other per-fs and subsystem-wide data as well. Fix a case of IN_MODIFIED being set without updating lfs_uinodes, resulting in a "lfs_uinodes < 0" panic. Fix a deadlock in lfs_putpages arising from the need to busy all pages in a block; unbusy any that had already been busied before starting over.

- Get rid of unused #ifdefs LFS_NO_PAGEMOVE and LFS_MALLOC_SUMMARY (both always true) and accompanying dead code. - When constructing write clusters in lfs_writeseg, if the block we are about to add is itself a cluster from GOP_WRITE, don't put a cluster in a cluster, just write the GOP_WRITE cluster on its own. This seems to represent a slight performance gain on my test machine. - Charge someone's rusage for writes on LFSes. It's difficult to tell who the "right" process to charge is; just charge whoever triggered the write.

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.

When unwiring pages in lfs_gop_write, deactivate them, under the theory that the pagedaemon wanted to free them last we knew.

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.

Deal with fragment size changes better. For each fragment that can exist on an on-disk inode, we keep a record of its size in struct inode, which is updated when we write the block to disk. The cleaner routines thus have ready access to what size is the correct size for this block, on disk. Fixed a related bug: if a file with fragments is being cleaned (fragments being cleaned) at the same time it is being extended beyond NDADDR blocks, we could write a bogus FINFO record that has a frag in the middle; when it was cleaned this would give back bogus file data. Don't write the indirect blocks in this case, since there is no need. lfs_fragextend and lfs_truncate no longer require the seglock, but instead take a shared lock, which the seglock locks exclusively.

Pull up revision 1.79 (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.

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.

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.

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.

Import of what I've been calling "LFSv2", that is, LFS with some features added that require changes to the on-disk data structures. These include: - 64-bit time in everything but inodes - User-specified segment offset, and segment size no longer restricted to PO2. - Serial number on segment summaries in addition to timestamp, and a new volume identifier, to make roll-forward feasible without fear of finding old data and thinking it was new. Although I think this version works at least as well as what's on the trunk, we're not done yet; hence this commit is going in on a branch and not on the trunk. Enhancements that are not here yet include fragment addressing, like FFS does, instead of block addressing.

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.)

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.

Allow the number of free segments reserved for the cleaner to be parametrized in the filesystem, defaulting to MIN_FREE_SEGS = 2 but set to something more reasonable at newfs_lfs time. Note the number of blocks that have been scheduled for writing but which are not yet on disk in an inode extension, i_lfs_effnblks. Move i_ffs_effnlink out of the ffs extension and onto the main inode, since it's used all over the shared code and the lfs extension would clobber it. At inode write time, indirect blocks and inode-held blocks of inodes that have i_lfs_effnblks != i_ffs_blocks are cleansed of UNWRITTEN disk addresses, so that these never make it to disk.

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 way LFS does block accounting, from trying to infer from the buffer cache flags, to marking the inode and/or indirect blocks with a special disk address UNWRITTEN==-2 when a block is accounted for. (This address is never written to disk, but only used in-core. This is essentially the same method of block accounting as on the UBC branch, where the buffer headers don't exist.) Make sure that truncation is handled properly, especially in the case of holey files. Fixes PR#9994.

Changes to stabilize LFS. The first two of these should also apply to the 1.4 branch. * Use a separate per-fs lock, instead of ufs_hashlock, to protect the Inode free list. This seems to prevent the "lockmgr: %d, not exclusive lock holder %d, unlocking" message I was mis-attributing last night to an unlocked vnode being passed to vrele. * Change calling semantics of lfs_ifind, to give better error reporting: If fed a struct buf, it can report the block number of the offending inode block as well as the inode number. * Back out rev 1.10 of lfs_subr.c, since the replacement code was slightly uglier while being functionally identical. * Make lfs_vunref use the same free list convention as vrele/vput, so that vget does not remove vnodes from a hash list they are not on.

If ifile blocks were written before dirops were complete, and then the system crashed, inodes could be allocated that were not referenced. (Though not a serious problem, it evidences itself in phase 4 of fsck_lfs.) Fix this by marking if_daddr with UNASSIGNED before the inodes are actually written; at mount time the ifile is checked for UNASSIGNED entries and any that are found are linked back into the free list. (The latter functionality should move into the roll-forward agent when it materializes.)

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.

Minor changes to the segment live bytes calculation. In particular, fixed a bug in fragment extension that could run the count negative. Also, don't overcount for inodes, and don't count segment summaries. Thus, for empty segments the live bytes count should now be exactly zero.

Pull-up of changes made to the trunk on Sunday [1.23->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.

lfs_truncate calls vinvalbuf to invalidate all currently-hald buffers, which in turn forces a flush of the vnode, whether or not it is involved in a dirop. (This can happen during a remove or rmdir, when the directory is shrunk.) Because of the nature of dirops, however, flushing a vnode involved in a dirop is disallowed (and was marked with a panic). This patch has lfs_truncate call a specialized vinvalbuf that only invalidates buffers following the new end-of-file, and thus does not require a flush. Also the panic is demoted, in case I missed any other path to lfs_vflush.

Make sysctl variable lfs_clean_vnhead do what it was supposed to do, namely, toggle whether vnodes loaded only for cleaning (as opposed to normal filesystem use) are freed to the *head* of the vnode free list, rather than the tail. This should avoid a possible cache flushing effect, if the cleaner cleans a segment containing a large number of live inodes.

Fixes to make dirops and lfs_vflush play together well. In particular, if we are short on vnodes, lfs_vflush from another process can grab a vnode that lfs_markv has already processed but not yet written; but lfs_markv holds the seglock. When lfs_vflush gets around to writing it, the context for copyin is gone. So, now lfs_markv calls copyin itself, rather than having lfs_writeseg do it.

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.
