6579ddcc26 Check for NULL pointer before freeing a struct sockaddr. m_freem() can handle
NULL, buf free() can't.

a76fb5eefa Yow! Completely change the way socket options are handled, eliminating
another specialized mbuf type in the process.  Also clean up some
of the cruft surrounding IPFW, multicast routing, RSVP, and other
ill-explored corners.

6adfc2e8bc If we get an ENOBUFS from the network, it's normally transient network
interface congestion (eg: nfs over a ppp link, etc).  Don't log these
for UDP mounts, and don't cause syscalls to fail with EINTR.
This stops the 'nfs send error 55' warnings.

If the error is because the system is really hosed, this is the least
of your problems...

863d5c8b68 Cast pointers to uintptr_t/intptr_t instead of to u_long/long,
respectively.  Most of the longs should probably have been
u_longs, but this changes is just to prevent warnings about
casts between pointers and integers of different sizes, not
to fix poorly chosen types.

c8ef0cb9cd fix buildworld hopefully be3fore anyone complains...
NFS_*TIMO should possibly be converted to sysctl vars (jkh's suggestion),
but in some cases it looks like nfs keeps a copy of the value in a struct

hash sizes are already ifdef'd KERNEL, so there aren't userland inpact
from them...

renamed to opt_nfsroot.h instead of the old opt_nfs.h....

a90040b583 Avoid an egcs pessimization for 64-bit signed division on i386's.
Pre-2.8 versions of gcc generate a call to __divdi3() for all 64-bit
signed divisions, but egcs optimizes them to a shift and fixup when
the divisor is a constant power of 2.  Unfortunately, it generates
a call to __cmpdi2() for the fixup, although all except possibly
ancient versions of gcc and egcs do ordinary 64-bit comparisons
inline.

1d5f38ac22 This commit fixes various 64bit portability problems required for
FreeBSD/alpha.  The most significant item is to change the command
argument to ioctl functions from int to u_long.  This change brings us
inline with various other BSD versions.  Driver writers may like to
use (__FreeBSD_version == 300003) to detect this change.

The prototype FreeBSD/alpha machdep will follow in a couple of days
time.

19ad2aa63b For the on-the-wire protocol, u_long -> u_int32_t; long -> int32_t;
int -> int32_t; u_short -> u_int16_t.  Also, use mode_t instead of u_short
for storing modes (mode_t is a u_int16_t).

e58631da3c NFS Jumbo commit part 1. Cosmetic and structural changes only. The aim
of this part of commits is to minimize unnecessary differences between
the other NFS's of similar origin.  Yes, there are gratuitous changes here
that the style folks won't like, but it makes the catch-up less difficult.

aa33f20993 When using NFSv3, use the remote server's idea of the maximum file size
rather than assuming 2^64.  It may not like files that big. :-)
On the nfs server, calculate and report the max file size as the point
that the block numbers in the cache would turn negative.
(ie: 1099511627775 bytes (1TB)).

One of the things I'm worried about however, is that directory offsets
are really cookies on a NFSv3 server and can be rather large, especially
when/if the server generates the opaque directory cookies by using a local
filesystem offset in what comes out as the upper 32 bits of the 64 bit
cookie.  (a server is free to do this, it could save byte swapping
depending on the native 64 bit byte order)

6d06da8101 Convert a couple of large allocations to use zones rather than malloc
for better packing.  This means that we can choose better values for the
various hash entries without having to try and get it all to fit within
an artificial power of two limit for malloc's sake.

ef0bb32854 Only ignore "owner" permissions selectively rather than always. In some
cases we ignore it (eg: read/write) to maintain chmod-after-open semantics
but in other cases we do care, eg: creating files, access() etc.  Never
ignore errors from VOP_ACCESS() on immutable files.

This apparently comes from BSDI (from Keith Bostic) via NetBSD.

1777a04b11 Allow control of the attribute cache timeouts at mount time.
We had run out of bits in the nfs mount flags, I have moved the internal
state flags into a seperate variable.  These are no longer visible via
statfs(), but I don't know of anything that looks at them.

964ce778b1 In the words of the submitter:
---------
Make callers of namei() responsible for releasing references or locks
instead of having the underlying filesystems do it.  This eliminates
redundancy in all terminal filesystems and makes it possible for stacked
transport layers such as umapfs or nullfs to operate correctly.

Quality testing was done with testvn, and lat_fs from the lmbench suite.

Some NFS client testing courtesy of Patrik Kudo.

vop_mknod and vop_symlink still release the returned vpp.  vop_rename
still releases 4 vnode arguments before it returns.  These remaining cases
will be corrected in the next set of patches.

9b703b1455 Eradicate the variable "time" from the kernel, using various measures.
"time" wasn't a atomic variable, so splfoo() protection were needed
around any access to it, unless you just wanted the seconds part.

Most uses of time.tv_sec now uses the new variable time_second instead.

gettime() changed to getmicrotime(0.

Remove a couple of unneeded splfoo() protections, the new getmicrotime()
is atomic, (until Bruce sets a breakpoint in it).

A couple of places needed random data, so use read_random() instead
of mucking about with time which isn't random.

Add a new nfs_curusec() function.

Mark a couple of bogosities involving the now disappeard time variable.

Update ffs_update() to avoid the weird "== &time" checks, by fixing the
one remaining call that passwd &time as args.

Change profiling in ncr.c to use ticks instead of time.  Resolution is
the same.

Add new function "tvtohz()" to avoid the bogus "splfoo(), add time, call
hzto() which subtracts time" sequences.

2aacd1ab4f Change the busy page mgmt, so that when pages are freed, they
MUST be PG_BUSY.  It is bogus to free a page that isn't busy,
because it is in a state of being "unavailable" when being
freed.  The additional advantage is that the page_remove code
has a better cross-check that the page should be busy and
unavailable for other use.  There were some minor problems
with the collapse code, and this plugs those subtile "holes."

Also, the vfs_bio code wasn't checking correctly for PG_BUSY
pages.  I am going to develop a more consistant scheme for
grabbing pages, busy or otherwise.  For now, we are stuck
with the current morass.

cd67bb82fe Lots of improvements, including restructring the caching and management
of vnodes and objects.  There are some metadata performance improvements
that come along with this.  There are also a few prototypes added when
the need is noticed.  Changes include:

1) Cleaning up vref, vget.
2) Removal of the object cache.
3) Nuke vnode_pager_uncache and friends, because they aren't needed anymore.
4) Correct some missing LK_RETRY's in vn_lock.
5) Correct the page range in the code for msync.

Be gentle, and please give me feedback asap.
