mrg d2397ac5f7 completely remove Mach VM support. all that is left is the all the
header files as UVM still uses (most of) these.

be necessary to obtain the information, as this fits the pathconf semantics
of `no association supported' better than `no limit available.'

mrg 1a8c7604f4 initial import of the new virtual memory system, UVM, into -current.
UVM was written by chuck cranor <chuck@maria.wustl.edu>, with some
minor portions derived from the old Mach code.  i provided some help
getting swap and paging working, and other bug fixes/ideas.  chuck
silvers <chuq@chuq.com> also provided some other fixes.

this is the rest of the MI portion changes.

this will be KNF'd shortly.  :-)

thorpej 98bb00f98f Fix alignment problems. From Frank van der Linden <fvdl@NetBSD.ORG>. 1997-10-20 22:08:44 +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 c3ce5f02ea Do negative lookup caching. Use a timestamp of the oldest negative cache
entry, so it can be checked against directory modification time for
validity.
1997-10-12 23:13:35 +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

fvdl 2c5bca83ed Don't assume that pointers into mbuf data remain valid across nfsm_dissect.
In readdirplus, don't keep such pointers but store the file attributes
in a variable instead until they are needed. Change nfsm_loadattr*
a bit so it can accept a direct pointer to an nfs_fattr structure.
1997-07-14 20:46:20 +00:00
drochner 8c0a9bab00 Don't cast 64bit (off_t) file sizes to vm_offset_t (32bit on many
architectures), truncate them intelligently instead.
The truncation is done centralized in vnode_pager.c.
This prevents from wrap-over effects when parts of large (>2^32 byte) files
are mmapped.
Don't allow to mmap above the numerical range of vm_offset_t.
This is considered a temporary solution until the vm system handles the
object sizes/offsets more cleanly.

fvdl 37986aa09a Fixes from BSDI (thanks go to Keith Bostic). Original RCS messages:
date: 1996/07/23 17:14:46;  author: donn;  state: Exp;  lines: +6 -4
Be sure to push out the last page of the file before truncating it.

date: 1996/10/14 22:41:20;  author: donn;  state: Exp;  lines: +2 -2
From Chris: Nfs_link() called vput() on the wrong vnode when aborting
from a cross-device link, which could (and did) lead to crashes.

date: 1996/10/24 16:43:43;  author: pjd;  state: Exp;  lines: +6 -2
Return EOPNOTSUPP when trying to do a setattr with flags.

===

Also (from BSDI too, but the RCS message did not quite describe the change
to this particular file well): move the EROFS a bit further down to
let VOP_ACCESS do it's work and return an 'expected' error value to
a possible layered filesystem.

fvdl be787cc073 * Fix some bugs in NQNFS (malformed RPC requests, no directory lease eviction)

* Don't ever try to sillyrename directories (from FreeBSD)

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.

cgd ce53653783 make the namei struct members ni_dirp and ni_next, and the componentname
struct member cn_nameptr 'const', since they should never be used to
modify the path name.  (Only the pathname buffer, cn_pnbuf, should be
modified.)  Propagate the const poisoning to code that uses the namei
and componentname structs.

  cleanup.
* Require the file system to decide whether or not linking and unlinking of
  directories is allowed, and disable it for all current file systems.

ghudson d61f235615 Add cookie support. Stash cookies in the word prior to the end of
each entry, and read them out in nfs_readdir().

Caveat: our current caching method for directory blocks uses the
server offset of the first directory entry as an identifier, so a
Linux emulation getdirentries() will wind up retrieving one block from
the NFS server for each directory entry, unnecessarily thrashing the
cache.  The situation isn't as bad for other emulations.

Instead of getblk(), we need to write a routine to scan each cache
block associated with vp to find a cookie that matches at some
directory entry.  Some later time.

mycroft b12f4a4409 For now, return EINVAL if the client needs cookies. 1995-10-09 11:25:30 +00:00
