thorpej 9a3664eccf Use the pool allocator and the "nointr" pool page allocator for NFS nodes
and vattr structures.

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.

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 acdbbd5215 Do locking around nfsnode hashing (perhaps even right this time!) 1997-07-07 23:34:55 +00:00
fvdl d9e3ab6bcb Revert until I have time to fix it today (lock applied wrongly). 1997-07-07 11:50:49 +00:00
fvdl 1680996881 Put lock around nfs node hashing to avoid race conditions, as MALLOC
or getnewvnode may block.

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.

Also, fix some time stamp bogosities.

cgd 3e0efb4d89 changes to make this work on systems where pointers & longs are 64 bits.
This is mostly just changes to make the stuff that goes over the wire
use fixed-size types.

cgd d071d1cf05 some prototype cleanup, eliminate/replace bogus types (e.g. quad and
u_quad) -> use better types (e.g. quad_t & u_quad_t in inodes),
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...
