Corrections to part of rev 1.140. lfs_bmapv, not lfs_markv, marks vnodes LFSI_BMAP and recycles them. This greatly reduces the writing leakage occurring when the filesystem has no space available for non-cleaning writes.

* 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.

Make sure all cached buffers with valid, not yet written data have been run through copy-on-write. Call fscow_run() with valid data where possible. The LP_UFSCOW hack is no longer needed to protect ffs_copyonwrite() against endless recursion. - Add a flag B_MODIFY to bread(), breada() and breadn(). If set the caller intends to modify the buffer returned. - Always run copy-on-write on buffers returned from ffs_balloc(). - Add new function ffs_getblk() that gets a buffer, assigns a new blkno, may clear the buffer and runs copy-on-write. Process possible errors from getblk() or fscow_run(). Part of PR kern/38664. Welcome to 4.99.63 Reviewed by: YAMAMOTO Takashi <yamt@netbsd.org>

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.

PR kern/37706 (forced unmount of file systems is unsafe): - Do reference counting for 'struct mount'. Each vnode associated with a mount takes a reference, and in turn the mount takes a reference to the vfsops. - Now that mounts are reference counted, replace the overcomplicated mount locking inherited from 4.4BSD with a recursable rwlock.

Replace struct lock on vnodes with a simpler lock object built on krwlock_t. This is a step towards removing lockmgr and simplifying vnode locking. Discussed on tech-kern.

Convert all the system call entry points from:
int foo(struct lwp *l, void *v, register_t *retval)
to:
int foo(struct lwp *l, const struct foo_args *uap, register_t *retval)
Fixup compat code to not write into 'uap' and (in some cases) to actually
pass a correctly formatted 'uap' structure with the right name to the
next routine.
A few 'compat' routines that just call standard ones have been deleted.
All the 'compat' code compiles (along with the kernels required to test
build it).
98% done by automated scripts.

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.

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.)

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().

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.

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.

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 1.67 (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.

Let lfs_bmapv fill in the bi_size member of the BLOCK_INFO structure, as well as bi_daddr. This lets the cleaner have an idea of what the size of this block was at the time it was written without having to refer to a segment header (e.g., in the file coalescing case). Tested on i386.

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.

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.)

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.

Fix errors observed while trying to fill the filesystem with yesterday's fixes: - Write copies of bfree and avail in the CLEANERINFO block, so the cleaner doesn't have to guess which superblock has the current information (if indeed any do). - Tighten up accounting of lfs_avail (more needs to be done). - When cleansing indirect blocks of UNWRITTEN, make sure not to mark them clean, since they'll need to be rewritten later.

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.

Pull up revision 1.40 (requested by perseant): Files removed (through unlink, rmdir) are now really removed, though the removal is postponed until the dirop is complete to ensure validity of the filesystem through a crash. Use a separate per-fs lock, instead of ufs_hashlock, to protect the inode free list. 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.

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.)

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 [1.27-1.28], 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.

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.
