8cc94a2371 Get rid of some MARKCACHED calls I thought better of. Make sure d_reclen
is aligned for off_t access, or things will break on the Alpha.

c3ce5f02ea Do negative lookup caching. Use a timestamp of the oldest negative cache

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.

9a7e1c1d7e Make this file deserve its name: add DHCP support, conditionalized
with NFS_BOOT_DHCP.
Don't increment xid between retries anymore, it is not required and
it increases the response time in case of a slow server.
Use common code with bootparam boot.

40db8a98f5 1. Allow to set a netmask (option NFS_BOOT_NETMASK) for the booting
interface. Without this, NFS_BOOT_NETMASK could be useless in
   subnetting envirinment.
2. Comment out unneeded NFS swap related stuff.
   Closes PR kern/3918.

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.

c437b55ca7 A filesystem may not support VFS_VGET (like msdosfs). If it doesn't,
the server code would always skip all dir entries for a readdirplus
operation. To avoid endlessly retrying clients, try VFS_VGET first,
and it it fails, return NFSERR_NOTSUPP so that client will fall
back to normal readdir operations.

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.

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.

28e824c9b7 Extend lookup handling for WebNFS. This means that nfs_namei deals
with full pathname lookups if a public filehandle is used, and that
it translates the '%' escapes (URL-style) in the same case. Also,
make nfsrv_fhtovp convert the public filehandle to the vp of the
publicly exported filesystem, as stored in the nfs_pub structure.

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.

b4e49cf0e9 Avoid nfsiods acquiring/releasing a lock, then acquiring it again, before
anyone else can get to it, by checking if a reply was received, and it
has thus become unnecessary to take the lock. From FreeBSD.

XXX I don't really like this, "locks" potentially suffer from the same
problem throughout the whole kernel; they should probably be FIFO everywhere.
