fvdl fb1a849339 Use different names for the "nfscon" label to tsleep(), so that it can
be seen in which one a process is sleeping.

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 43e1b9384f * Deal with servers that don't give complete FSINFO (like NT)
From Olaf Seibert <rhialto@polder.ubc.kun.nl> (PR 3687)
* Make an attempt to check the maximum filesize before attempting
  a write to the server, as write RPCs will typically happen
  asynchronously, and the process will not see the error.
  Fixes problems with unexpectly truncated files at 4G
* Pass up errors in nfs_writerpc correctly

mrg 295af85e9e remove swap configuration. 1997-06-12 17:12:17 +00:00
gwr 01adc15274 Minor reorganization of nfs_mountroot code to simplify BOOTP support.
The RPC/bootparamd calls to get the root and swap paths are now done
in nfs_boot_init() instead of nfs_boot_getfh(), so the latter now just
does the RPC/mountd call.  Also changed some panics into error returns.

fvdl 64fcae7bcb * Make sure a new socket is created when switching to/from NOCONN with
a mount
* Add extra printf statements to hopefully get some more info on lockups,
  specifically when a send error is ignored.

thorpej 647fa23dc4 - Add nfs_mountroot to nfs_vfsops.
- Only attempt to mount NFS root on a DV_IFNET class device.
- If nfs_boot_init() failes, return the error code to the caller.

cgd 90688fce27 Change the second and third args to struct vfsops' (*vfs_mount)() to
'const char *', and 'void *', respectively.  The second arg is taken directly
from user arguments, and is const there, so must be const in the prototypes
and functions.  The third arg is also taken directly from user arguments.
It doesn't have to be changed, but since it's cleaner to keep the type
the same as the user arg's type, and I'm already making the 'const char *'
change...

thorpej f02e8b3cf0 Make NFSSERVER work without NFSCLIENT. This is achieved by splitting
the client and server/shared data initialization into separate functions,
and calling the server/shared initialization directly from main().
Problem noted in PR #1308 (Kenneth Stailey) and PR #1780 (Chris Demetriou).
Fix suggested in PR #1780 by Chris Demetriou, and munged a bit by me,
and OK'd by Frank van der Linden <fvdl@netbsd.org>.

thorpej aa25de69d1 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.

fvdl 735944405b Enhancements from Matthias Drochner:
- Try V3 first for diskless booting. Fall back to V2 if V3 fails.
	- optionally (option NFS_BOOT_TCP) try a TCP mount first
	  for diskless booting. Fall back to UDP if it fails.
	- Enable switching between UDP and TCP for remounts.

pk 6e8ba625ef Ignore the mountpoint's `v_usecount' in nfs_unmount() if MNT_FORCE is on.
This takes care of two related problems:
	- `umount -f' wouldn't work if someone's working directory is
	  the filesystem root.
	- vfs_unmountall() would complain about a busy `/' on a
	  diskless setup.

pk e052143aab When updating an NFS mountpoint, we cannot just increase `rsize' or `wsize'
without also adjusting the corresponding socket buffers. We could probably
call sbrelease/sbreserve/soreserve ourselves without much harm, but we'd
have to duplicate much of the logic in nfs_connect(). In stead, blow the
socket away entirely and let nfs_connect() do its job again.
