fvdl bf714cf896 Drop vnode lock before removing the sillyrename file, to avoid a
lock-o-death.

fvdl a4c70394dc On VOP_GETATTR failure in nfs_nget, call vgone() to get rid
of the vnode that was just created. Suggested by Enami.

fvdl c18aae5b9f In nfs_inactive there's no need anymore for an extra refcount around
nfs_vinvalbuf, since it has a real lock on the vnode now, so getnewvnode
will not hijack it.

bjh21 33daa8de6b New kernel option, NFS_V2_ONLY, which aims to reduce the NFS client to just
that required to support NFSv2 mounts.  Not finished yet, but already
provides some 44k of saving in code size on arm26.  More savings, and some
documentation, are still to come.

jdolecek 89015c4648 Add new VFS op routine - vfs_done and call it on filesystem detach
in vfs_detach(). vfs_done may free global filesystem's resources,
typically those allocated in respective filesystem's init function.
Needed so those filesystems which went in via LKM have a chance to
clean after themselves before unloading. This fixes random panics
when LKM for filesystem using pools was loaded and unloaded several
times.

For each leaf filesystem, add appropriate vfs_done routine.

fvdl 5a7300902c 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.

wrstuden 379a26972f Modify file systems to deal with struct lock in struct vnode. All leaf
fs's other than nfs use genfs_lock() for locking.

Modify lookup routines to set PDIRUNLOCK when they unlock the parrent.

chs f64abc7b4c add flags arg to hashinit(), to pass to malloc(). 1998-02-07 02:44:44 +00:00
fvdl 1cf3a3db94 * 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.
1997-10-19 01:46:15 +00:00
fvdl 7f7d814e67 * 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.

fvdl 7a970115da Fixes from BSDI (thanks go to Keith Bostic). Original RCS messages:

Because NFS doesn't implement vnode locking, nfs_inactive() doesn't really
have the vnode locked and hence it can't reliably access the vnode after
it performs a blocking operation.  We remove one blocking call and push
the no-op VOP_UNLOCK higher so that we don't access the vnode after we
delete the sillyrename file.  This should prevent crashes we've seen in
which the vnode turned into a UFS vnode and caused a panic in ufs_unlock()
when we tried to 'unlock' it.

Kirk's change to not corrupt files after a delete.

date: 1996/11/08 19:53:45;  author: donn;  state: Exp;  lines: +16 -4
Krik's change to solve the paradox that vclean() calls nfs_inactive()
with VXLOCK set on the vnode, and nfs_inactive() was calling vget()
to get a reference on the vnode, which in turn hung on VXLOCK.
Nfs_inactive() now checks v_usecount to make sure that the vnode
is not coming from vclean() before it does a vget().

fvdl 744438b408 Don't set sillyrename field to 0 for directories, as it's in a union with
the head of the cookie list. Fixes PR 3215, fix supplied by
Hiroshi Tezuka <tezuka@trc.rwcp.or.jp>. Should also fix M_NFSDIROFF
memory leak.

some cleanup.

cgd f7003b8eba 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...
