fvdl c7a919199a Silently clear NFSMNT_NOCONN if it's a TCP mount. 1997-02-22 02:48:26 +00:00
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.

cgd d73abf41aa avoid unnecessary checks of m_get/MGET/etc.'s return values. When
they're called with M_WAIT, they are defined to never return NULL.

fvdl 2847784948 * Make mounts with symlinks work (needed for direct mounts with amd). PR #1917
* Never change the NQNFS flag and/or version when just doing an update mount.
  Fixes a problem that made diskless booting impossible under some
  circumstances.

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.
