This is the kernel Lite/2 commit. There are some requisite userland changes, so don't expect to be able to run the kernel as-is (very well) without the appropriate Lite/2 userland changes. The system boots and can mount UFS filesystems. Untested: ext2fs, msdosfs, NFS Known problems: Incorrect Berkeley ID strings in some files. Mount_std mounts will not work until the getfsent library routine is changed. Reviewed by: various people Submitted by: Jeffery Hsu <hsu@freebsd.org>

* @(#)nfs_vnops.c 8.16 (Berkeley) 5/27/95
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.

#include <vm/vm_extern.h>
NOTE: libkvm, w, ps, 'top', and any other utility which depends on struct proc or any VM system structure will have to be rebuilt!!! Much needed overhaul of the VM system. Included in this first round of changes: 1) Improved pager interfaces: init, alloc, dealloc, getpages, putpages, haspage, and sync operations are supported. The haspage interface now provides information about clusterability. All pager routines now take struct vm_object's instead of "pagers". 2) Improved data structures. In the previous paradigm, there is constant confusion caused by pagers being both a data structure ("allocate a pager") and a collection of routines. The idea of a pager structure has escentially been eliminated. Objects now have types, and this type is used to index the appropriate pager. In most cases, items in the pager structure were duplicated in the object data structure and thus were unnecessary. In the few cases that remained, a un_pager structure union was created in the object to contain these items. 3) Because of the cleanup of #1 & #2, a lot of unnecessary layering can now be removed. For instance, vm_object_enter(), vm_object_lookup(), vm_object_remove(), and the associated object hash list were some of the things that were removed. 4) simple_lock's removed. Discussion with several people reveals that the SMP locking primitives used in the VM system aren't likely the mechanism that we'll be adopting. Even if it were, the locking that was in the code was very inadequate and would have to be mostly re-done anyway. The locking in a uni-processor kernel was a no-op but went a long way toward making the code difficult to read and debug. 5) Places that attempted to kludge-up the fact that we don't have kernel thread support have been fixed to reflect the reality that we are really dealing with processes, not threads. The VM system didn't have complete thread support, so the comments and mis-named routines were just wrong. We now use tsleep and wakeup directly in the lock routines, for instance. 6) Where appropriate, the pagers have been improved, especially in the pager_alloc routines. Most of the pager_allocs have been rewritten and are now faster and easier to maintain. 7) The pagedaemon pageout clustering algorithm has been rewritten and now tries harder to output an even number of pages before and after the requested page. This is sort of the reverse of the ideal pagein algorithm and should provide better overall performance. 8) Unnecessary (incorrect) casts to caddr_t in calls to tsleep & wakeup have been removed. Some other unnecessary casts have also been removed. 9) Some almost useless debugging code removed. 10) Terminology of shadow objects vs. backing objects straightened out. The fact that the vm_object data structure escentially had this backwards really confused things. The use of "shadow" and "backing object" throughout the code is now internally consistent and correct in the Mach terminology. 11) Several minor bug fixes, including one in the vm daemon that caused 0 RSS objects to not get purged as intended. 12) A "default pager" has now been created which cleans up the transition of objects to the "swap" type. The previous checks throughout the code for swp->pg_data != NULL were really ugly. This change also provides the rudiments for future backing of "anonymous" memory by something other than the swap pager (via the vnode pager, for example), and it allows the decision about which of these pagers to use to be made dynamically (although will need some additional decision code to do this, of course). 13) (dyson) MAP_COPY has been deprecated and the corresponding "copy object" code has been removed. MAP_COPY was undocumented and non- standard. It was furthermore broken in several ways which caused its behavior to degrade to MAP_PRIVATE. Binaries that use MAP_COPY will continue to work correctly, but via the slightly different semantics of MAP_PRIVATE. 14) (dyson) Sharing maps have been removed. It's marginal usefulness in a threads design can be worked around in other ways. Both #12 and #13 were done to simplify the code and improve readability and maintain- ability. (As were most all of these changes) TODO: 1) Rewrite most of the vnode pager to use VOP_GETPAGES/PUTPAGES. Doing this will reduce the vnode pager to a mere fraction of its current size. 2) Rewrite vm_fault and the swap/vnode pagers to use the clustering information provided by the new haspage pager interface. This will substantially reduce the overhead by eliminating a large number of VOP_BMAP() calls. The VOP_BMAP() filesystem interface should be improved to provide both a "behind" and "ahead" indication of contiguousness. 3) Implement the extended features of pager_haspage in swap_pager_haspage(). It currently just says 0 pages ahead/behind. 4) Re-implement the swap device (swstrategy) in a more elegant way, perhaps via a much more general mechanism that could also be used for disk striping of regular filesystems. 5) Do something to improve the architecture of vm_object_collapse(). The fact that it makes calls into the swap pager and knows too much about how the swap pager operates really bothers me. It also doesn't allow for collapsing of non-swap pager objects ("unnamed" objects backed by other pagers).

Introduced a type `vop_t' for vnode operation functions and used it 1138 times (:-() in casts and a few more times in declarations. This change is null for the i386. The type has to be `typedef int vop_t(void *)' and not `typedef int vop_t()' because `gcc -Wstrict-prototypes' warns about the latter. Since vnode op functions are called with args of different (struct pointer) types, neither of these function types is any use for type checking of the arg, so it would be preferable not to use the complete function type, especially since using the complete type requires adding 1138 casts to avoid compiler warnings and another 40+ casts to reverse the function pointer conversions before calling the functions.

* Special device vnode ops

Introduced a type `vop_t' for vnode operation functions and used it 1138 times (:-() in casts and a few more times in declarations. This change is null for the i386. The type has to be `typedef int vop_t(void *)' and not `typedef int vop_t()' because `gcc -Wstrict-prototypes' warns about the latter. Since vnode op functions are called with args of different (struct pointer) types, neither of these function types is any use for type checking of the arg, so it would be preferable not to use the complete function type, especially since using the complete type requires adding 1138 casts to avoid compiler warnings and another 40+ casts to reverse the function pointer conversions before calling the functions.

Improve the queuing algorithms used by NFS' asynchronous i/o. The existing mechanism uses a global queue for some buffers and the vp->b_dirtyblkhd queue for others. This turns sequential writes into randomly ordered writes to the server, affecting both read and write performance. The existing mechanism also copes badly with hung servers, tending to block accesses to other servers when all the iods are waiting for a hung server. The new mechanism uses a queue for each mount point. All asynchronous i/o goes through this queue which preserves the ordering of requests. A simple mechanism ensures that the iods are shared out fairly between active mount points. This removes the sysctl variable vfs.nfs.dwrite since the new queueing mechanism removes the old delayed write code completely. This should go into the 2.2 branch.

* What an NFS client should do upon close after writing is a debatable issue.
* Most NFS clients push delayed writes to the server upon close, basically for
* two reasons:
* 1 - So that any write errors may be reported back to the client process
* doing the close system call. By far the two most likely errors are
* NFSERR_NOSPC and NFSERR_DQUOT to indicate space allocation failure.
* 2 - To put a worst case upper bound on cache inconsistency between
* multiple clients for the file.
* There is also a consistency problem for Version 2 of the protocol w.r.t.
* not being able to tell if other clients are writing a file concurrently,
* since there is no way of knowing if the changed modify time in the reply
* is only due to the write for this client.
* (NFS Version 3 provides weak cache consistency data in the reply that
* should be sufficient to detect and handle this case.)
*
* The current code does the following:
* for NFS Version 2 - play it safe and flush/invalidate all dirty buffers
* for NFS Version 3 - flush dirty buffers to the server but don't invalidate
* or commit them (this satisfies 1 and 2 except for the
* case where the server crashes after this close but
* before the commit RPC, which is felt to be "good
* enough". Changing the last argument to nfs_flush() to
* a 1 would force a commit operation, if it is felt a
* commit is necessary now.
* for NQNFS - do nothing now, since 2 is dealt with via leases and
* 1 should be dealt with via an fsync() system call for
* cases where write errors are important.

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>

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.

Various fixes from frank@fwi.uva.nl (Frank van der Linden) via rick@snowhite.cis.uoguelph.ca: 1. Clear B_NEEDCOMMIT in nfs_write to make sure that dirty data is correctly send to the server. If a buffer was dirtied when it was in the B_DELWRI+B_NEEDCOMMIT state, the state of the buffer was left unchanged and when the buffer was later cleaned, just a commit rpc was made to the server to complete the previous write. Clearing B_NEEDCOMMIT ensures that another write is made to the server. 2. If a server returned a server (for whatever reason) returned an answer to a write RPC that implied that fewer bytes than requested were written, bad things would happen. 3. The setattr operation passed on the atime in stead of the mtime to the server. The fix is trivial. 4. XIDs always started at 0, but this caused some servers (older DEC OSF/1 3.0 so I've been told) who had very long-lasting XID caches to get confused if, after a reboot of a BSD client, RPCs came in with a XID that had in the past been used before from that client. Patch is to use the current time in seconds as a starting point for XIDs. The patch below is not perfect, because it requires the root fs to be mounted first. This is because of the check BSD systems do, comparing FS time to system time. Reviewed by: Bruce Evans, Terry Lambert.

Prevent a mapped root which appears on the server as e.g. nobody from accessing files which it shouldn't be able to. This required a better approximation of VOP_ACCESS for NFSv2 (NFSv3 already has an ACCESS rpc which is a better solution) and adding a call to VOP_ACCESS from VOP_LOOKUP.

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>

Fix a few bugs with NFS and mmap caused by NFS' use of b_validoff and b_validend. The changes to vfs_bio.c are a bit ugly but hopefully can be tidied up later by a slight redesign. PR: kern/2573, kern/2754, kern/3046 (possibly) Reviewed by: dyson

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>

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.

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.

* If the tvp exists and is in use, sillyrename it before doing the

Fix (properly, I hope) 'panic: sillyrename dir' crash that can happen if you do: % cd /nfsdir % mkdir -p foo/foo % mv foo/foo . nfs_sillyrename() self-destructs if you try to sillyrename a directory, however nfs_rename() can be coerced into doing just that by the above sequence of commands. To avoid this, nfs_rename() now checks that v_type of the 'destination' vnode != VDIR before attempting the sillyrename. The server correctly handles this particular situation by returning ENOTEMPTY on the rename() attempt. I asked if this was the correct fix for this on -hackers but nobody ever answered. This is a 2.2 candidate.

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>

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>

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>

This is the kernel Lite/2 commit. There are some requisite userland changes, so don't expect to be able to run the kernel as-is (very well) without the appropriate Lite/2 userland changes. The system boots and can mount UFS filesystems. Untested: ext2fs, msdosfs, NFS Known problems: Incorrect Berkeley ID strings in some files. Mount_std mounts will not work until the getfsent library routine is changed. Reviewed by: various people Submitted by: Jeffery Hsu <hsu@freebsd.org>

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>

1. Add a {pointer, v_id} pair to the vnode to store the reference to the ".." vnode. This is cheaper storagewise than keeping it in the namecache, and it makes more sense since it's a 1:1 mapping. 2. Also handle the case of "." more intelligently rather than stuff the namecache with pointless entries. 3. Add two lists to the vnode and hang namecache entries which go from or to this vnode. When cleaning a vnode, delete all namecache entries it invalidates. 4. Never reuse namecache enties, malloc new ones when we need it, free old ones when they die. No longer a hard limit on how many we can have. 5. Remove the upper limit on namelength of namecache entries. 6. Make a global list for negative namecache entries, limit their number to a sysctl'able (debug.ncnegfactor) fraction of the total namecache. Currently the default fraction is 1/16th. (Suggestions for better default wanted!) 7. Assign v_id correctly in the face of 32bit rollover. 8. Remove the LRU list for namecache entries, not needed. Remove the #ifdef NCH_STATISTICS stuff, it's not needed either. 9. Use the vnode freelist as a true LRU list, also for namecache accesses. 10. Reuse vnodes more aggresively but also more selectively, if we can't reuse, malloc a new one. There is no longer a hard limit on their number, they grow to the point where we don't reuse potentially usable vnodes. A vnode will not get recycled if still has pages in core or if it is the source of namecache entries (Yes, this does indeed work :-) "." and ".." are not namecache entries any longer...) 11. Do not overload the v_id field in namecache entries with whiteout information, use a char sized flags field instead, so we can get rid of the vpid and v_id fields from the namecache struct. Since we're linked to the vnodes and purged when they're cleaned, we don't have to check the v_id any more. 12. NFS knew about the limitation on name length in the namecache, it shouldn't and doesn't now. Bugs: The namecache statistics no longer includes the hits for ".." and "." hits. Performance impact: Generally in the +/- 0.5% for "normal" workstations, but I hope this will allow the system to be selftuning over a bigger range of "special" applications. The case where RAM is available but unused for cache because we don't have any vnodes should be gone. Future work: Straighten out the namecache statistics. "desiredvnodes" is still used to (bogusly ?) size hash tables in the filesystems. I have still to find a way to safely free unused vnodes back so their number can shrink when not needed. There is a few uses of the v_id field left in the filesystems, scheduled for demolition at a later time. Maybe a one slot cache for unused namecache entries should be implemented to decrease the malloc/free frequency.

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>

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

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>

Fixed a panic in nfs_writevp(). Lite2 provided a fix for a silly missing-parentheses bug, but this exposed a misplaced vfs_busy_pages(). This bug cost a factor of 2.5-3 in nfsv3 write performance! It should be fixed in 2.2. Removed some debugging code that gets triggered often in normal operation. There are still many backwards diagnostics (#define DIAGNOSTIC gives no diagnostics).

Second batch of cleanup changes. This time mostly making a lot of things static and some unused variables here and there.

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>

Replaced bogus macros for dummy devswitch entries by functions. These functions went away: enosys (hasn't been used for some time) enxio enodev enoioctl (was used only once, actually for a vop) if_tun.c: Continued cleaning up... conf.h: Probably fixed the type of d_reset_t. It is hard to tell the correct type because there are no non-dummy device reset functions. Removed last vestige of ambiguous sleep message strings.
