SVN rev 228520 on 2011-12-15 02:26:53Z by delphij Honor NFSv3 commit call (RFC 1813, Section 3.3.21) where when count is 0, the full length from offset is being flushed. Note that for now VOP_FSYNC does not support offset and length parameters so we still do the same full VOP_FSYNC. This issue was reported at FreeNAS support site as FreeNAS ticket #1096.

SVN rev 228185 on 2011-12-01 18:46:28Z by jhb Enhance the sequential access heuristic used to perform readahead in the NFS server and reuse it for writes as well to allow writes to the backing store to be clustered. - Use a prime number for the size of the heuristic table (1017 is not prime). - Move the logic to locate a heuristic entry from the table and compute the sequential count out of VOP_READ() and into a separate routine. - Use the logic from sequential_heuristic() in vfs_vnops.c to update the seqcount when a sequential access is performed rather than just increasing seqcount by 1. This lets the clustering count ramp up faster. - Allow for some reordering of RPCs and if it is detected leave the current seqcount as-is rather than dropping back to a seqcount of 1. Also, when out of order access is encountered, cut seqcount in half rather than dropping it all the way back to 1 to further aid with reordering. - Fix the new NFS server to properly update the next offset after a successful VOP_READ() so that the readahead actually works. Some of these changes came from an earlier patch by Bjorn Gronwall that was forwarded to me by bde@. Discussed with: bde, rmacklem, fs@ Submitted by: Bjorn Gronwall (1, 4) MFC after: 2 weeks

This was overlooked during v6 -> v13 switch. PR: kern/139076 Reported by: Sean Winn <sean@gothic.net.au> r197458: Close race in zfs_zget(). We have to increase usecount first and then check for VI_DOOMED flag. Before this change vnode could be reclaimed between checking for the flag and increasing usecount. r197459: Before calling vflush(FORCECLOSE) mark file system as unmounted so the following vnops will fail. This is very important, because without this change vnode could be reclaimed at any point, even if we increased usecount. The only way to ensure that vnode won't be reclaimed was to lock it, which would be very hard to do in ZFS without changing a lot of code. With this change simply increasing usecount is enough to be sure vnode won't be reclaimed from under us. To be precise it can still be reclaimed but we won't be able to see it, because every try to enter ZFS through VFS will result in EIO. The only function that cannot return EIO, because it is needed for vflush() is zfs_root(). Introduce ZFS_ENTER_NOERROR() macro that only locks z_teardown_lock and never returns EIO. r197497: Switch to fletcher4 as the default checksum algorithm.

SVN rev 191990 on 2009-05-11 15:33:26Z by attilio Remove the thread argument from the FSD (File-System Dependent) parts of the VFS. Now all the VFS_* functions and relating parts don't want the context as long as it always refers to curthread. In some points, in particular when dealing with VOPs and functions living in the same namespace (eg. vflush) which still need to be converted, pass curthread explicitly in order to retain the old behaviour. Such loose ends will be fixed ASAP. While here fix a bug: now, UFS_EXTATTR can be compiled alone without the UFS_EXTATTR_AUTOSTART option. VFS KPI is heavilly changed by this commit so thirdy parts modules needs to be recompiled. Bump __FreeBSD_version in order to signal such situation.

SVN rev 185586 on 2008-12-03 17:54:09Z by kan Change nfsserver slightly so that it does not trip over the timestamp validation code on ZFS. Problem: when opening file with O_CREAT|O_EXCL NFS has to jump through extra hoops to ensure O_EXCL semantics. Namely, client supplies of 8 bytes (NFSX_V3CREATEVERF) bytes of verification data to uniquely identify this create request. Server then creates a new file with access mode 0, copies received 8 bytes into va_atime member of struct vattr and attempt to set the atime on file using VOP_SETATTR. If that succeeds, it fetches file attributes with VOP_GETATTR and verifies that atime timestamps match. If timestamps do not match, NFS server concludes it has probbaly lost the race to another process creating the file with the same name and bails with EEXIST. This scheme works OK when exported FS is FFS, but if underlying filesystem is ZFS _and_ server is running 64bit kernel, it breaks down due to sanity checking in zfs_setattr function, which refuses to accept any timestamps which have tv_sec that cannot be represented as 32bit int. Since struct timespec fields are 64 bit integers on 64bit platforms and server just copies NFSX_V3CREATEVERF bytes info va_atime, all eight bytes supplied by client end up in va_atime.tv_sec, forcing it out of valid 32bit range. The solution this change implements is simple: it treats NFSX_V3CREATEVERF as two 32bit integers and unpacks them separately into va_atime.tv_sec and va_atime.tv_nsec respectively, thus guaranteeing that tv_sec remains in 32 bit range and ZFS remains happy.

SVN rev 184588 on 2008-11-03 10:38:00Z by dfr Implement support for RPCSEC_GSS authentication to both the NFS client and server. This replaces the RPC implementation of the NFS client and server with the newer RPC implementation originally developed (actually ported from the userland sunrpc code) to support the NFS Lock Manager. I have tested this code extensively and I believe it is stable and that performance is at least equal to the legacy RPC implementation. The NFS code currently contains support for both the new RPC implementation and the older legacy implementation inherited from the original NFS codebase. The default is to use the new implementation - add the NFS_LEGACYRPC option to fall back to the old code. When I merge this support back to RELENG_7, I will probably change this so that users have to 'opt in' to get the new code. To use RPCSEC_GSS on either client or server, you must build a kernel which includes the KGSSAPI option and the crypto device. On the userland side, you must build at least a new libc, mountd, mount_nfs and gssd. You must install new versions of /etc/rc.d/gssd and /etc/rc.d/nfsd and add 'gssd_enable=YES' to /etc/rc.conf. As long as gssd is running, you should be able to mount an NFS filesystem from a server that requires RPCSEC_GSS authentication. The mount itself can happen without any kerberos credentials but all access to the filesystem will be denied unless the accessing user has a valid ticket file in the standard place (/tmp/krb5cc_<uid>). There is currently no support for situations where the ticket file is in a different place, such as when the user logged in via SSH and has delegated credentials from that login. This restriction is also present in Solaris and Linux. In theory, we could improve this in future, possibly using Brooks Davis' implementation of variant symlinks. Supporting RPCSEC_GSS on a server is nearly as simple. You must create service creds for the server in the form 'nfs/<fqdn>@<REALM>' and install them in /etc/krb5.keytab. The standard heimdal utility ktutil makes this fairly easy. After the service creds have been created, you can add a '-sec=krb5' option to /etc/exports and restart both mountd and nfsd. The only other difference an administrator should notice is that nfsd doesn't fork to create service threads any more. In normal operation, there will be two nfsd processes, one in userland waiting for TCP connections and one in the kernel handling requests. The latter process will create as many kthreads as required - these should be visible via 'top -H'. The code has some support for varying the number of service threads according to load but initially at least, nfsd uses a fixed number of threads according to the value supplied to its '-n' option.

- Complete part of the unfinished bufobj work by consistently using BO_LOCK/UNLOCK/MTX when manipulating the bufobj. - Create a new lock in the bufobj to lock bufobj fields independently. This leaves the vnode interlock as an 'identity' lock while the bufobj is an io lock. The bufobj lock is ordered before the vnode interlock and also before the mnt ilock. - Exploit this new lock order to simplify softdep_check_suspend(). - A few sync related functions are marked with a new XXX to note that we may not properly interlock against a non-zero bv_cnt when attempting to sync all vnodes on a mountlist. I do not believe this race is important. If I'm wrong this will make these locations easier to find. Reviewed by: kib (earlier diff) Tested by: kris, pho (earlier diff)

VOP_LOCK1() (and so VOP_LOCK()) and VOP_UNLOCK() are only used in conjuction with 'thread' argument passing which is always curthread. Remove the unuseful extra-argument and pass explicitly curthread to lower layer functions, when necessary. KPI results broken by this change, which should affect several ports, so version bumping and manpage update will be further committed. Tested by: kris, pho, Diego Sardina <siarodx at gmail dot com>

vn_lock() is currently only used with the 'curthread' passed as argument. Remove this argument and pass curthread directly to underlying VOP_LOCK1() VFS method. This modify makes the code cleaner and in particular remove an annoying dependence helping next lockmgr() cleanup. KPI results, obviously, changed. Manpage and FreeBSD_version will be updated through further commits. As a side note, would be valuable to say that next commits will address a similar cleanup about VFS methods, in particular vop_lock1 and vop_unlock.

Move vnode-to-file-handle translation from vfs_vptofh to vop_vptofh method. This way we may support multiple structures in v_data vnode field within one file system without using black magic. Vnode-to-file-handle should be VOP in the first place, but was made VFS operation to keep interface as compatible as possible with SUN's VFS. BTW. Now Solaris also implements vnode-to-file-handle as VOP operation. VFS_VPTOFH() was left for API backward compatibility, but is marked for removal before 8.0-RELEASE.

Push Giant a bit further off the NFS server in a number of straight forward cases by converting from unconditional acquisition of Giant around vnode operations to conditional acquisition: - Remove nfsrv_access_withgiant(), and cause nfsrv_access() to now assert that Giant will be held if it is required for the vnode. - Add nfsrv_fhtovp_locked(), which will drop the NFS server lock if required, and modify nfsrv_fhtovp() to conditionally acquire Giant if required. - In the VOP's not dealing with more than one vnode at a time (i.e., not involving a lookup), conditionally acquire Giant. This removes Giant use for MPSAFE file systems for a number of quite important RPCs, including getattr, read, write. It leaves unconditional Giant acquisitions in vnode operations that interact with the name space or more than one vnode at a time as these require further work. Tested by: kris Reviewed by: kib

Manage the ucred for the NFS server using the crget/crfree API defined in
kern_prot.c. This API handles reference counting among many other things.
Notably, if MAC is compiled into the kernel, it will properly initialize the
MAC labels when the ucred is allocated.
This work is in preparation for a new MAC entry point which will be responsible
for properly initializing policy specific labels for the NFS server credential.
Utilization of the crfree/crget APIs reduce the complexity associated with
this label's management.

Additionally, to reduce complexity, the ucred persist as long as the NFS

Remove the unused credential argument from VOP_FSYNC() and VFS_SYNC().
I'm not sure why a credential was added to these in the first place, it is
not used anywhere and it doesn't make much sense:
The credentials for syncing a file (ability to write to the
file) should be checked at the system call level.
Credentials for syncing one or more filesystems ("none")
should be checked at the system call level as well.
If the filesystem implementation needs a particular credential
to carry out the syncing it would logically have to the
cached mount credential, or a credential cached along with
any delayed write data.

Correct a bug in nfsrv_create() where a call to nfsrv_access() might
be made holding the NFS server mutex. To clean this up, introduce a
version of the function, nfsrv_access_withgiant(), that expects the
NFS server mutex to already have been dropped and Giant acquired.
Wrap nfsrv_access() around this. This permits callers to more
efficiently check access if they're in a code block performing VFS
operations, and can be substitited for the nfsrv_access() call that
triggered this bug.

The socket code upcalls into the NFS server using the so_upcall mechanism so that early processing on mbufs can be performed before a context switch to the NFS server threads. Because of this, if the socket code is running without Giant, the NFS server also needs to be able to run the upcall code without relying on the presence on Giant. This change modifies the NFS server to run using a "giant code lock" covering operation of the whole subsystem. Work is in progress to move to data-based locking as part of the NFSv4 server changes. Introduce an NFS server subsystem lock, 'nfsd_mtx', and a set of macros to operate on the lock: NFSD_LOCK_ASSERT() Assert nfsd_mtx owned by current thread NFSD_UNLOCK_ASSERT() Assert nfsd_mtx not owned by current thread NFSD_LOCK_DONTCARE() Advisory: this function doesn't care NFSD_LOCK() Lock nfsd_mtx NFSD_UNLOCK() Unlock nfsd_mtx Constify a number of global variables/structures in the NFS server code, as they are not modified and contain constants only: nfsrvv2_procid nfsrv_nfsv3_procid nonidempotent nfsv2_repstat nfsv2_type nfsrv_nfsv3_procid nfsrvv2_procid nfsrv_v2errmap nfsv3err_null nfsv3err_getattr nfsv3err_setattr nfsv3err_lookup nfsv3err_access nfsv3err_readlink nfsv3err_read nfsv3err_write nfsv3err_create nfsv3err_mkdir nfsv3err_symlink nfsv3err_mknod nfsv3err_remove nfsv3err_rmdir nfsv3err_rename nfsv3err_link nfsv3err_readdir nfsv3err_readdirplus nfsv3err_fsstat nfsv3err_fsinfo nfsv3err_pathconf nfsv3err_commit nfsrv_v3errmap There are additional structures that should be constified but due to their being passed into general purpose functions without const arguments, I have not yet converted. In general, acquire nfsd_mtx when accessing any of the global NFS structures, including struct nfssvc_sock, struct nfsd, struct nfsrv_descript. Release nfsd_mtx whenever calling into VFS, and acquire Giant for calls into VFS. Giant is not required for any part of the operation of the NFS server with the exception of calls into VFS. Giant will never by acquired in the upcall code path. However, it may operate entirely covered by Giant, or not. If debug.mpsafenet is set to 0, the system calls will acquire Giant across all operations, and the upcall will assert Giant. As such, by default, this enables locking and allows us to test assertions, but should not cause any substantial new amount of code to be run without Giant. Bugs should manifest in the form of lock assertion failures for now. This approach is similar (but not identical) to modifications to the BSD/OS NFS server code snapshot provided by BSDi as part of their SMPng snapshot. The strategy is almost the same (single lock over the NFS server), but differs in the following ways: - Our NFS client and server code bases don't overlap, which means both fewer bugs and easier locking (thanks Peter!). Also means NFSD_*() as opposed to NFS_*(). - We make broad use of assertions, whereas the BSD/OS code does not. - Made slightly different choices about how to handle macros building packets but operating with side effects. - We acquire Giant only when entering VFS from the NFS server daemon threads. - Serious bugs in BSD/OS implementation corrected -- the snapshot we received was clearly a work in progress.

Fix a bug in nfsrv_read() that caused the replies to certain NFSv3 short read operations at the end of a file to not have the "eof" flag set as they should. The problem is that the requested read count was compared against the rounded-up reply data length instead of the actual reply data length. This bug appears to have been introduced in revision 1.78 (June 1999). It causes first-time reads of certain file sizes (e.g 4094 bytes) to fail with EIO on a RedHat 9.0 NFSv3 client.

Replace the global buffer hash table with per-vnode splay trees using a
methodology similar to the vm_map_entry splay and the VM splay that Alan
Cox is working on. Extensive testing has appeared to have shown no
increase in overhead.
Disadvantages
Dirties more cache lines during lookups.
Not as fast as a hash table lookup (but still N log N and optimal
when there is locality of reference).
Advantages
vnode->v_dirtyblkhd is now perfectly sorted, making fsync/sync/filesystem
syncer operate more efficiently.
I get to rip out all the old hacks (some of which were mine) that tried
to keep the v_dirtyblkhd tailq sorted.
The per-vnode splay tree should be easier to lock / SMPng pushdown on
vnodes will be easier.
This commit along with another that Alan is working on for the VM page
global hash table will allow me to implement ranged fsync(), optimize
server-side nfs commit rpcs, and implement partial syncs by the
filesystem syncer (aka filesystem syncer would detect that someone is
trying to get the vnode lock, remembers its place, and skip to the
next vnode).
Note that the buffer cache splay is somewhat more complex then other splays
due to special handling of background bitmap writes (multiple buffers with
the same lblkno in the same vnode), and B_INVAL discontinuities between the
old hash table and the existence of the buffer on the v_cleanblkhd list.

Change the suser() API to take advantage of td_ucred as well as do a general cleanup of the API. The entire API now consists of two functions similar to the pre-KSE API. The suser() function takes a thread pointer as its only argument. The td_ucred member of this thread must be valid so the only valid thread pointers are curthread and a few kernel threads such as thread0. The suser_cred() function takes a pointer to a struct ucred as its first argument and an integer flag as its second argument. The flag is currently only used for the PRISON_ROOT flag.

Add a flags parameter to VFS_VGET to pass through the desired locking flags when acquiring a vnode. The immediate purpose is to allow polling lock requests (LK_NOWAIT) needed by soft updates to avoid deadlock when enlisting other processes to help with the background cleanup. For the future it will allow the use of shared locks for read access to vnodes. This change touches a lot of files as it affects most filesystems within the system. It has been well tested on FFS, loopback, and CD-ROM filesystems. only lightly on the others, so if you find a problem there, please let me (mckusick@mckusick.com) know.

It is required by VOP_CREATE, VOP_MKNOD, VOP_SYMLINK and VOP_MKDIR that va_mode of the supplied attributes is filled in with a valid file mode (i.e not VNOVAL, and only ALLPERM bits set). However, some NFS server op functions didn't guarantee this for all possible request messages: If a V3 client chose not include to a mode specification, we could end up creating an ffs inode with mode 0177777, requiring a manual fsck on the next reboot. Fix this by setting va_mode to 0 before calling the VOP if a mode hasn't been supplied by the client. In nfsrv_symlink(), S_IFMT bits supplied by a V2 client could end up in the va_mode passed to VOP_SYMLINK with similar effects. We now use the macro nfstov_mode() to correctly mask the bits.

Fix a few NFSv2 issues that slipped in during the big cleanup. The semantics of the nfsm_reply() macro were changed so that the caller has to explicitly handle the V2 error case, whereas before, nfsm_reply() did a `goto nfsmout' then. A few server ops (setattr, readlink, create, mkdir) weren't updated to match, so errors in the V2 case could cause protocol hangs and leaked mbufs. Correct some comments that describe the old nfsm_reply behaviour. [older, harmless nit] Remove the unnecessary `nfsmreply0' label in nfsrv_create(), since for its users, the main `ereply' label does the same thing.

Avoid passing the variable `tl' to functions that just use it for temporary storage. In the old NFS code it wasn't at all clear if the value of `tl' was used across or after macro calls, but I'm fairly confident that the convention was to keep its use local. Each ex-macro function now uses a local version of this variable, so all of the double-indirection goes away. The only exception to the `local use' rule for `tl' is nfsm_clget(), which is left unchanged by this commit. Reviewed by: peter

Fix some problems that were introduced in revision 1.97. Instead of returning an error code to the caller, NFS server op routines must themselves build an error reply and return 0 to the caller. This is achieved by replacing the erroneous return statements with code that jumps forward to the op function's reply code. We need to be careful to ensure that the 'struct mount' pointer is NULL though, so that the final vn_finished_write() call becomes a no-op. Reviewed by: mckusick, dillon

* Rename M_WAIT mbuf subsystem flag to M_TRYWAIT. This is because calls with M_WAIT (now M_TRYWAIT) may not wait forever when nothing is available for allocation, and may end up returning NULL. Hopefully we now communicate more of the right thing to developers and make it very clear that it's necessary to check whether calls with M_(TRY)WAIT also resulted in a failed allocation. M_TRYWAIT basically means "try harder, block if necessary, but don't necessarily wait forever." The time spent blocking is tunable with the kern.ipc.mbuf_wait sysctl. M_WAIT is now deprecated but still defined for the next little while. * Fix a typo in a comment in mbuf.h * Fix some code that was actually passing the mbuf subsystem's M_WAIT to malloc(). Made it pass M_WAITOK instead. If we were ever to redefine the value of the M_WAIT flag, this could have became a big problem.

Add snapshots to the fast filesystem. Most of the changes support the gating of system calls that cause modifications to the underlying filesystem. The gating can be enabled by any filesystem that needs to consistently suspend operations by adding the vop_stdgetwritemount to their set of vnops. Once gating is enabled, the function vfs_write_suspend stops all new write operations to a filesystem, allows any filesystem modifying system calls already in progress to complete, then sync's the filesystem to disk and returns. The function vfs_write_resume allows the suspended write operations to begin again. Gating is not added by default for all filesystems as for SMP systems it adds two extra locks to such critical kernel paths as the write system call. Thus, gating should only be added as needed. Details on the use and current status of snapshots in FFS can be found in /sys/ufs/ffs/README.snapshot so for brevity and timelyness is not included here. Unless and until you create a snapshot file, these changes should have no effect on your system (famous last words).

Make FreeBSD less conservative in determining when to return a cookie
error for a directory. I have made this change after a great deal of
review although I cannot be absolutely sure that this meets the spec.
The issue devolves into whether changes in an underlying (UFS) directory
can cause NFS directory blocks to be renumbered. My read of the code
indicates that NFS directory blocks will not be renumbered, which means
that the cookies should still remain valid after a change is made to
the underlying directory. This being the case, a cookie error should
not be returned when a change is made to the underlying directory and,
instead, the NFS client should rely on mtime detection to invalidate and
reload the directory.
The use of mtime is problematic in of itself, due to insufficient
resolution, which is why I believe the original conservative error
handling was done. Still, there have been dozens of bug reports by
people needing solaris<->FreeBSD interoperability and these have to
be accomodated.

Asynchronized client-side nfs_commit. NFS commit operations were
previously issued synchronously even if async daemons (nfsiod's) were
available. The commit has been moved from the strategy code to the doio
code in order to asynchronize it.
Removed use of lastr in preparation for removal of vnode->v_lastr. It
has been replaced with seqcount, which is already supported by the system
and, in fact, gives us a better heuristic for sequential detection then
lastr ever did.
Made major performance improvements to the server side commit. The
server previously fsync'd the entire file for each commit rpc. The
server now bawrite()s only those buffers related to the offset/size
specified in the commit rpc.
Note that we do not commit the meta-data yet. This works still needs
to be done.
Note that a further optimization can be done (and has not yet been done)
on the client: we can merge multiple potential commit rpc's into a
single rpc with a greater file offset/size range and greatly reduce
rpc traffic.

MFC: correct sanity test length calculation in nfsrv_readdirplus() so that we don't accidentally overfill the mbuf chain when using 32K read/write sizes. Stops "cd /nfsdir; du" from certain NFSv3 TCP clients from crashing the system.

Correct the sanity test length calculation in nfsrv_readdirplus(): len is being incremented by 4 bytes too few each time through the loop, which allows more data into the mbuf chain that we really want. In the worst case, when we're using 32K read/write sizes with a TCP client, this causes readdirplus replies to sometimes exceed NFS_MAXPACKET which leads to a panic. This problem cropped up for me using an IRIX 6.5.4 NFSv3 TCP client with 32K read/write sizes, however supposedly it can be triggered by WinNT NFS servers too. In theory, it can probably be triggered by any NFS v3 implementation using TCP as long as it's using the maxiumum block size. Reviewed by: Matthew Dillon <dillon@backplane.com>

Divorce "dev_t" from the "major|minor" bitmap, which is now called
udev_t in the kernel but still called dev_t in userland.
Provide functions to manipulate both types:
major() umajor()
minor() uminor()
makedev() umakedev()
dev2udev() udev2dev()
For now they're functions, they will become in-line functions
after one of the next two steps in this process.
Return major/minor/makedev to macro-hood for userland.
Register a name in cdevsw[] for the "filedescriptor" driver.
In the kernel the udev_t appears in places where we have the
major/minor number combination, (ie: a potential device: we
may not have the driver nor the device), like in inodes, vattr,
cdevsw registration and so on, whereas the dev_t appears where
we carry around a reference to a actual device.
In the future the cdevsw and the aliased-from vnode will be hung
directly from the dev_t, along with up to two softc pointers for
the device driver and a few houskeeping bits. This will essentially
replace the current "alias" check code (same buck, bigger bang).
A little stunt has been provided to try to catch places where the
wrong type is being used (dev_t vs udev_t), if you see something
not working, #undef DEVT_FASCIST in kern/kern_conf.c and see if
it makes a difference. If it does, please try to track it down
(many hands make light work) or at least try to reproduce it
as simply as possible, and describe how to do that.
Without DEVT_FASCIST I belive this patch is a no-op.
Stylistic/posixoid comments about the userland view of the <sys/*.h>
files welcome now, from userland they now contain the end result.
Next planned step: make all dev_t's refer to the same devsw[] which
means convert BLK's to CHR's at the perimeter of the vnodes and
other places where they enter the game (bootdev, mknod, sysctl).

This Implements the mumbled about "Jail" feature. This is a seriously beefed up chroot kind of thing. The process is jailed along the same lines as a chroot does it, but with additional tough restrictions imposed on what the superuser can do. For all I know, it is safe to hand over the root bit inside a prison to the customer living in that prison, this is what it was developed for in fact: "real virtual servers". Each prison has an ip number associated with it, which all IP communications will be coerced to use and each prison has its own hostname. Needless to say, you need more RAM this way, but the advantage is that each customer can run their own particular version of apache and not stomp on the toes of their neighbors. It generally does what one would expect, but setting up a jail still takes a little knowledge. A few notes: I have no scripts for setting up a jail, don't ask me for them. The IP number should be an alias on one of the interfaces. mount a /proc in each jail, it will make ps more useable. /proc/<pid>/status tells the hostname of the prison for jailed processes. Quotas are only sensible if you have a mountpoint per prison. There are no privisions for stopping resource-hogging. Some "#ifdef INET" and similar may be missing (send patches!) If somebody wants to take it from here and develop it into more of a "virtual machine" they should be most welcome! Tools, comments, patches & documentation most welcome. Have fun...

This change brings us inline with various other BSD versions. Driver writers may like to use (__FreeBSD_version == 300003) to detect this change. The prototype FreeBSD/alpha machdep will follow in a couple of days time.

When using NFSv3, use the remote server's idea of the maximum file size rather than assuming 2^64. It may not like files that big. :-) On the nfs server, calculate and report the max file size as the point that the block numbers in the cache would turn negative. (ie: 1099511627775 bytes (1TB)). One of the things I'm worried about however, is that directory offsets are really cookies on a NFSv3 server and can be rather large, especially when/if the server generates the opaque directory cookies by using a local filesystem offset in what comes out as the upper 32 bits of the 64 bit cookie. (a server is free to do this, it could save byte swapping depending on the native 64 bit byte order) Obtained from: NetBSD

This eliminates redundancy in all terminal filesystems and makes it possible for stacked transport layers such as umapfs or nullfs to operate correctly. Quality testing was done with testvn, and lat_fs from the lmbench suite. Some NFS client testing courtesy of Patrik Kudo. vop_mknod and vop_symlink still release the returned vpp. vop_rename still releases 4 vnode arguments before it returns.

Eradicate the variable "time" from the kernel, using various measures. "time" wasn't a atomic variable, so splfoo() protection were needed around any access to it, unless you just wanted the seconds part. Most uses of time.tv_sec now uses the new variable time_second instead. gettime() changed to getmicrotime(0. Remove a couple of unneeded splfoo() protections, the new getmicrotime() is atomic, (until Bruce sets a breakpoint in it). A couple of places needed random data, so use read_random() instead of mucking about with time which isn't random. Add a new nfs_curusec() function. Mark a couple of bogosities involving the now disappeard time variable. Update ffs_update() to avoid the weird "== &time" checks, by fixing the one remaining call that passwd &time as args. Change profiling in ncr.c to use ticks instead of time. Resolution is the same. Add new function "tvtohz()" to avoid the bogus "splfoo(), add time, call hzto() which subtracts time" sequences.

Change the busy page mgmt, so that when pages are freed, they MUST be PG_BUSY. It is bogus to free a page that isn't busy, because it is in a state of being "unavailable" when being freed. The additional advantage is that the page_remove code has a better cross-check that the page should be busy and unavailable for other use. There were some minor problems with the collapse code, and this plugs those subtile "holes." Also, the vfs_bio code wasn't checking correctly for PG_BUSY pages. I am going to develop a more consistant scheme for grabbing pages, busy or otherwise. For now, we are stuck with the current morass.

Fix all areas of the system (or at least all those in LINT) to avoid storing socket addresses in mbufs. (Socket buffers are the one exception.) A number of kernel APIs needed to get fixed in order to make this happen. Also, fix three protocol families which kept PCBs in mbufs to not malloc them instead. Delete some old compatibility cruft while we're at it, and add some new routines in the in_cksum family.

Implement the async mount option for NFSv3. This makes NFS pretend that all writes sent to the server were synchronous and therefore no commits are needed. This is the same as the vfs.nfs.async variable on the server but allows each client to choose whether to work this way. Also make the vfs.nfs.async variable do the 'right' thing for NFSv3, i.e. pretend that the write was synchronous.

Even though this looks like it, this is not a complex code change. The interface into the "VMIO" system has changed to be more consistant and robust. Essentially, it is now no longer necessary to call vn_open to get merged VM/Buffer cache operation, and exceptional conditions such as merged operation of VBLK devices is simpler and more correct. This code corrects a potentially large set of problems including the problems with ktrace output and loaded systems, file create/deletes, etc. Most of the changes to NFS are cosmetic and name changes, eliminating a layer of subroutine calls. The direct calls to vput/vrele have been re-instituted for better cross platform compatibility. Reviewed by: davidg

Changes to support version 3 of the NFS protocol. The version 2 support has been tested (client+server) against FreeBSD-2.0, IRIX 5.3 and FreeBSD-current (using a loopback mount). The version 2 support is stable AFAIK. The version 3 support has been tested with a loopback mount and minimally against an IRIX 5.3 server. It needs more testing and may have problems. I have patched amd to support the new variable length filehandles although it will still only use version 2 of the protocol. Before booting a kernel with these changes, nfs clients will need to at least build and install /usr/sbin/mount_nfs. Servers will need to build and install /usr/sbin/mountd. NFS diskless support is untested. Obtained from: Rick Macklem <rick@snowhite.cis.uoguelph.ca>

Backed out one part of rev 1.13. In this one case, two references to the vnode are gained, but only one reference to the object is gained. The object reference is (correctly) lost by the nfsrv_vrele() at the exit point of the nfsrv_link function. The bug is easily seen by doing a standard "link" operation to a 2.0.5 server (ln foo bar). The system will immediately panic with "object deallocated too many times". This fixes the panic reported today by ohki@gssm.otsuka.tsukuba.ac.jp. (will be) Reviewed by: John Dyson

These changes embody the support of the fully coherent merged VM buffer cache, much higher filesystem I/O performance, and much better paging performance. It represents the culmination of over 6 months of R&D. The majority of the merged VM/cache work is by John Dyson. The following highlights the most significant changes. Additionally, there are (mostly minor) changes to the various filesystem modules (nfs, msdosfs, etc) to support the new VM/buffer scheme. vfs_bio.c: Significant rewrite of most of vfs_bio to support the merged VM buffer cache scheme. The scheme is almost fully compatible with the old filesystem interface. Significant improvement in the number of opportunities for write clustering. vfs_cluster.c, vfs_subr.c Upgrade and performance enhancements in vfs layer code to support merged VM/buffer cache. Fixup of vfs_cluster to eliminate the bogus pagemove stuff. vm_object.c: Yet more improvements in the collapse code. Elimination of some windows that can cause list corruption. vm_pageout.c: Fixed it, it really works better now. Somehow in 2.0, some "enhancements" broke the code. This code has been reworked from the ground-up. vm_fault.c, vm_page.c, pmap.c, vm_object.c Support for small-block filesystems with merged VM/buffer cache scheme. pmap.c vm_map.c Dynamic kernel VM size, now we dont have to pre-allocate excessive numbers of kernel PTs. vm_glue.c Much simpler and more effective swapping code. No more gratuitous swapping. proc.h Fixed the problem that the p_lock flag was not being cleared on a fork. swap_pager.c, vnode_pager.c Removal of old vfs_bio cruft to support the past pseudo-coherency. Now the code doesn't need it anymore. machdep.c Changes to better support the parameter values for the merged VM/buffer cache scheme. machdep.c, kern_exec.c, vm_glue.c Implemented a seperate submap for temporary exec string space and another one to contain process upages. This eliminates all map fragmentation problems that previously existed. ffs_inode.c, ufs_inode.c, ufs_readwrite.c Changes for merged VM/buffer cache. Add "bypass" support for sneaking in on busy buffers. Submitted by: John Dyson and David Greenman
