 1.77  07-Dec-2024  riastradh sys/nfs/nfs: Add some missing includes and include guards.

Fix up some minor KNF issues while here.

No functional change intended (except to enable things to build that
might not have built before because of previously required #include
ordering).
 1.76  21-Oct-2021  andvar branches: 1.76.10;
fix various typos, mainly in comments, but also in man pages and log messages.
 1.75  18-Jul-2021  dholland Abolish all the silly indirection macros for initializing vnode ops tables.

These are things of the form #define foofs_op genfs_op, or #define
foofs_op genfs_eopnotsupp, or similar. They serve no purpose besides
obfuscation, and have gotten cutpasted all over everywhere.
 1.74  27-May-2021  simonb Remove nfs_putpages() prototype; it's not defined anywhere.
 1.73  30-May-2014  hannken branches: 1.73.44; 1.73.46;
Change NFS from rbtree to vcache.
 1.72  25-Sep-2010  matt branches: 1.72.18; 1.72.32;
Rename rb.h to rbtree.h, as it is more appropriate (c.f. ptree.h). Also
helps find code that hasn't been updated to use the new rbtree API.
 1.71  14-Mar-2009  dsl branches: 1.71.2; 1.71.4;
Remove all the __P() from sys (excluding sys/dist)
Diff checked with grep and MK1 eyeball.
i386 and amd64 GENERIC and sys still build.
 1.70  02-Jan-2009  christos branches: 1.70.2;
protect sillyrename with _KERNEL
 1.69  02-Jan-2009  ad - Don't vput() a vnode that we do not hold locked.
- Eliminate one of the few remaining uses of LK_CANRECURSE.
 1.68  22-Oct-2008  matt branches: 1.68.2; 1.68.4;
Change NFS to use a RB-tree for its FH->nfsnode lookups.
 1.67  25-Jan-2008  ad branches: 1.67.6; 1.67.10; 1.67.16;
Remove VOP_LEASE. Discussed on tech-kern.
 1.66  10-Aug-2007  yamt branches: 1.66.2; 1.66.8;
- instead of scanning an array of iods, maintain a list of idle iods.
- make nfs_getset_niothreads MP friendly.
 1.65  08-Aug-2007  yamt push kernel_lock a little.
 1.64  20-Jul-2007  yamt branches: 1.64.4; 1.64.6;
- fix decreasing of vfs.nfs.iothreads after the recent partial merge
of vmlocking.
- don't make nfsiod exit with requests left.
- make NFSSVC_BIOD a dummy so that nfsiod can be simplified.
 1.63  29-Apr-2007  yamt branches: 1.63.2;
include condvar.h. pointed by Kurt Schreiner.
 1.62  29-Apr-2007  yamt use mutex and condver.
 1.61  15-Feb-2007  yamt branches: 1.61.2; 1.61.6; 1.61.8;
use mutex and rwlock rather than lockmgr.
 1.60  28-Dec-2006  yamt remove several nqnfs definitions.
 1.59  27-Dec-2006  yamt remove nqnfs.
 1.58  17-Oct-2006  christos another variable should have been _KERNEL only.
 1.57  17-Oct-2006  christos don't expose kernel variables to userland.
 1.56  14-May-2006  elad branches: 1.56.8; 1.56.10;
integrate kauth.
 1.55  11-Dec-2005  christos branches: 1.55.4; 1.55.6; 1.55.8; 1.55.10; 1.55.12;
merge ktrace-lwp.
 1.54  26-Jan-2005  yamt branches: 1.54.6;
handle a really empty directory, which doesn't have even the dot entry.
 1.53  09-Jan-2005  yamt branches: 1.53.2; 1.53.4;
invalidate cache if filesize is changed besides our activity
because it means that we're out of sync with the server.
 1.52  08-Jan-2005  yamt nfs_lookup: check n_nctime for positive entries as well to improve
cache consistency.
 1.51  14-Dec-2004  yamt redirect some VOPs which shouldn't be used for nfs
to genfs_badop (ie. panic).
 1.50  26-Oct-2004  yamt since daddr_t is 64-bit these days, simply use nfs directory cookies
as buffer cache indexes. regress/sys/fs/getdents is now supposed to work.
fix PR/27112.
 1.49  15-Sep-2004  yamt fix access-after-free bugs in dircache code by refcounting nfsdircache.
PR/26864.
 1.48  24-Aug-2004  yamt nfs_request: a workaround for servers doing "maproot".
for i/o requests which are expected not to fail due to permission
to mimic unix file open semantics (READ, WRITE, COMMIT),
try two credentials. namely, the file owner's one and open time one.
remember which credential worked in per-file basis and try it first
next time to minimize number of retries.
ideas from Chuck Silvers. PR/23716 and PR/24987.
 1.47  27-May-2004  yamt remove an unused instance of VOP_UPDATE.
 1.46  12-Mar-2004  yamt branches: 1.46.2;
shrink sizeof struct nfsnode by putting exclusive members into union.
 1.45  12-Mar-2004  yamt introduce a macro NFS_INVALIDATE_ATTRCACHE and use it
instead of "n_attrstamp = 0".
 1.44  26-Sep-2003  yamt change n_mtime from time_t to timespec in order to improve
cache consistency.
(1 second granularity is too loose these days.)
 1.43  17-Sep-2003  yamt change nctime to timespec from time_t.
there can be too many activities in a second.
 1.42  07-Aug-2003  agc Move UCB-licensed code from 4-clause to 3-clause licence.

Patches provided by Joel Baker in PR 22364, verified by myself.
 1.41  30-Jul-2003  yamt vrecycle removed nfs vnodes.
not perfect, but enough for most cases.
 1.40  07-May-2003  yamt branches: 1.40.2;
simple lock for nfs iod.
 1.39  09-Apr-2003  yamt update a comment to follow the previous change.
 1.38  09-Apr-2003  yamt make per-iod datas together.
 1.37  01-Dec-2002  matt Make sure these all agree on the same definitons of various variables.
 1.36  23-Oct-2002  jdolecek merge kqueue branch into -current

kqueue provides a stateful and efficient event notification framework
currently supported events include socket, file, directory, fifo,
pipe, tty and device changes, and monitoring of processes and signals

kqueue is supported by all writable filesystems in NetBSD tree
(with exception of Coda) and all device drivers supporting poll(2)

based on work done by Jonathan Lemon for FreeBSD
initial NetBSD port done by Luke Mewburn and Jason Thorpe
 1.35  21-Oct-2002  yamt fix a page locking deadlock problem for nfs.

add a flag that specify if the file can be truncated safely or not
to nfsm_loadattr and friends. when it isn't safe, just mark the nfsnode
as "should be truncated later".

ok'ed by Frank van der Linden and Chuck Silvers.
close kern/18036.
 1.34  15-Sep-2001  chs 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.
 1.33  28-May-2001  chs branches: 1.33.2; 1.33.4;
add a genfs_mmap() and change all of the disk-based filesystems
to implement VOP_MMAP() with the genfs version, in preparation for
actually using this VOP.
 1.32  06-Feb-2001  fvdl branches: 1.32.2;
Do actual vnode locking for NFS.
 1.31  27-Nov-2000  chs Initial integration of the Unified Buffer Cache project.
 1.30  19-Sep-2000  fvdl Add fields to deal with commit ranges.
 1.29  30-Mar-2000  simonb branches: 1.29.4;
Delete redundant decl of nfs_vget() - it's in <nfs/nfsmount.h>.
 1.28  29-Nov-1999  fvdl Insert an extra VOP_ACCESS check in nfs_lookup, to avoid cached access
mishaps for lookup and getattr. Closes PR 8884.

While at it, cache access RPCs.
 1.27  10-Aug-1998  matthias branches: 1.27.2; 1.27.6; 1.27.8; 1.27.12; 1.27.18;
create miscfs/genfs/genfs_vnops.c:genfs_enoioctl and make all the other
filesystems use it instead of a private version.
 1.26  25-Jun-1998  thorpej - Rename nqnfs_vop_lease_check() to genfs_lease_check(). If NFSSERVER is
not in the kernel, genfs_lease_check() is simply a no-op. This allows
LKM'd file systems to be exported (previously did not work properly
due to a compile-time decision based on -DNFSSERVER).
- defopt NFSSERVER
 1.25  01-Mar-1998  fvdl Merge with Lite2 + local changes
 1.24  19-Oct-1997  fvdl * Implement optional 32 <-> 64 bit directory cookie translation. This uses
the directory cache as translation table. See nfs_subs.c for comments.
Makes the code a bit more complex to look at than I would have liked,
but doesn't affect the speed of the default behavior.
* Optimize caching behavior a bit when buffers are invalidated.
* Save some RPCs in readdir operations by not bothering if there is
a small amount left to do to fill the buffer. It'll be done in the
next RPC with a larger chunk anyway. Wastes a bit of buffer space
but is faster.
* Make n_vattr an allocated vattr struct. This avoids nfsnode bloat,
and is friendlier to the malloc routines.
 1.23  16-Oct-1997  christos Fix the location of the NFS_SMALLFH
 1.22  12-Oct-1997  fvdl Do negative lookup caching. Use a timestamp of the oldest negative cache
entry, so it can be checked against directory modification time for
validity.
 1.21  10-Oct-1997  fvdl * New directory entry caching system. Provides full caching of any
directory cookie that may be thrown back at us from userspace, up
to a size limit. Fixes double entry problem.
* Split flags for internal and external use in the NFS mount structure.
* Fix some buffer structure fields that weren're being used correctly.
* Fix missing directory cache inval call in nfs_open.
* Limit on NFS_DIRBLKSIZ no longer needed, bumped to the more reasonable
value of 8k.
* Various other things that I forget, all related to the dir caching
somehow, though.
 1.20  11-Apr-1997  kleink branches: 1.20.4;
Implement a POSIX compliant genfs VOP_SEEK() and use it in the appropriate
places; by Chris G. Demetriou and myself.
 1.19  02-Dec-1996  thorpej NFS performance improvement from Doug Rabson/FreeBSD:

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.

some cleanup.
 1.8  21-Apr-1994  cgd blow away all vestiges of nfsnode locking.
(1) it's unnecessary
(2) it causes machines to hang (yup!)
(3) it'd be gone in a few days anyway (it'd been yanked out
of 4.4-Lite by macklem long ago)
It was only there because macklem couldn't originally decide if things
should be locked, or not...
 1.7  15-Feb-1994  pk Update {a,m}time vnode attributes on special files a la ufs_vnode.c,

the routine checking for remote changes is quite simplistic, but hopefully
doing it's job well enough
