ce02431ffa * Change sysctl from using linker_set to construct its tree using SLISTs.
This makes it possible to change the sysctl tree at runtime.

* Change KLD to find and register any sysctl nodes contained in the loaded
  file and to unregister them when the file is unloaded.

1c7c3c6a86 This is a rather large commit that encompasses the new swapper,
changes to the VM system to support the new swapper, VM bug
    fixes, several VM optimizations, and some additional revamping of the
    VM code.  The specific bug fixes will be documented with additional
    forced commits.  This commit is somewhat rough in regards to code
    cleanup issues.

8e203b83a7 Undo #undef KERNEL hack for vnode.h to avoid vnode_if.h.
XXX It probably makes sense to have a flag for bsd.kern.mk to avoid these
    rules.
XXX IO_NDELAY seems to be the main reason for it, when used in a cdevsw
    read or write "flag" context.  Perhaps a redundant declaration
    somewhere like sys/conf.h might help remove the need for vnode.h in
    these device drivers in the first place.

831d27a9f5 Installed the second patch attached to kern/7899 with some changes suggested
by bde, a few other tweaks to get the patch to apply cleanly again and
some improvements to the comments.

This change closes some fairly minor security holes associated with
F_SETOWN, fixes a few bugs, and removes some limitations that F_SETOWN
had on tty devices.  For more details, see the description on the PR.

Because this patch increases the size of the proc and pgrp structures,
it is necessary to re-install the includes and recompile libkvm,
the vinum lkm, fstat, gcore, gdb, ipfilter, ps, top, and w.

5158516f4e In an attempt to reduce the huge number of differences between the
FreeBSD repository version of this file and the isdn4bsd version,
adopt those changes from the i4b version that make this file
BSD-version independent.  I attempted to avoid uglifying this file too
much, thus deviated a little from the i4b version (and hope they will
adopt the changes, too).

The diffs mostly concentrate on:

. #include differences between the systems
. different callout handling between FreeBSD vs. Net/OpenBSD
. interface naming (Net/OpenBSD store the ASCII name including the
  unit # in struct ifnet, FreeBSD only the name)
. use of random() in FreeBSD vs. time-based pseudo-randomization in
  Net/OpenBSD (for loopback detection ad CHAP challenges -- i
  assume at least OpenBSD could also benefit from random(), but that's
  the way i've got this file)
. interface address list elements are named a little differently
  between FreeBSD and Net/OpenBSD

I attempted to segregate those compat fixes from other code fixes and
enhancements.

c7323482f4 One-liner: add a call to the underlying device driver's SIOCDELMULTI
ioctl() routine at the end of if_delmulti() so that interfaces with
hardware multicast filtering can update their filters in a timely
manner.

If the interface doesn't support hardware multicast filtering, then
reception of multicast frames is done using 'promiscious mode' or
'capture all multicast frames' mode and software filtering in the
kernel. In this case, it doesn't matter if if_delmulti() ever does
an SCIODELMULTI on the interface or not: if MULTICAST support is
enabled, then we join the 'all hosts' group when the interface is
configured, and remain in it until the interface is brought down.
Without hardware filtering, joining one group means joining all
groups, so it makes no difference if we call the SIOCDELMULTI
routine.

If the interface does support hardware multicast filtering, then
by not reprogramming the hardware filter in if_delmulti(), we have
to wait until somebody calls if_setmulti(), during which time the
interface is receiving frames for multicast groups in which we are
no longer interested.

several new features are added:
	- support vc/vp shaping
	- support pvc shadow interface

code cleanup:
	- remove WMAYBE related code.  ENI WMAYBE DMA doen't work.
	- remove updating if_lastchange for every packet.
	- BPF related code is moved to midway.c as it should be.
	  (bpfwrite should work if atm_pseudohdr and LLC/SNAP are
	  prepended.)
	- BPF link type is changed to DLT_ATM_RFC1483.
	  BPF now understands only LLC/SNAP!! (because bpf can't
	  handle variable link header length.)
	  It is recommended to use LLC/SNAP instead of NULL
	  encapsulation for various reasons.  (BPF, IPv6,
	  interoperability, etc.)

the code has been used for months in ALTQ and KAME IPv6.

c086febef5 Don't attempt to optimize the space allocated for bpf headers if
sizeof(struct bpf_hdr) > 20.  20 is normal on 32-bit systems with
32-bit alignment, but we still assume that the last 2 bytes of the
struct are unnecessary padding on such systems.  On systems with
64-bit longs, struct timeval is bloated to 16 bytes, so bpf headers
certainly don't fit in 18 bytes.

Remove lots'o'hacks.
looutput is now static.

Other callers who want to use loopback to allow shortcutting
should call the special entrypoint for this, if_simloop(), which is
specifically designed for this purpose. Using looutput for this purpose
was problematic, particularly with bpf and trying to keep track
of whether one should be using the charateristics of the loopback interface
or the interface (e.g. if_ethersubr.c) that was requesting the loopback.
There was a whole class of errors due to this mis-use each of which had
hacks to cover them up.

Consists largly of hack removal :-)

NetBSD, ported to FreeBSD by Pierre Beyssac <pb@fasterix.freenix.org> and
minorly tweaked by me.
This is a standard part of FreeBSD, but must be enabled with:
"sysctl -w net.inet.ip.fastforwarding=1" ...and of course forwarding must
also be enabled. This should probably be modified to use the zone
allocator for speed and space efficiency. The current algorithm also
appears to lose if the number of active paths exceeds IPFLOW_MAX (256),
in which case it wastes lots of time trying to figure out which cache
entry to drop.

"time" wasn't a atomic variable, so splfoo() protection were needed
around any access to it, unless you just wanted the seconds part.

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.

09410d0f8b On most other systems "out there", <net/if.h> does not require the caller
to #include <sys/time.h> first.  I've lost count of the number of times
I've had to patch this in porting code.  The problem is the
"struct timeval ifi_lastchange" in the mib stats.  (most other systems don't
have this, until 4.4bsd anyway).

2cc2df490e Add preliminary support for IEEE 802.1Q VLAN tagging. It doesn't actually
work reliably yet (I've had panics), but it does seem to occasionally
be able to transmit and receive syntactically-correct packets.
Also fixes one of if_ethersubr.c's legion style bugs, and removes
the hostcache code from standard kernels---the code that depends on it
is not going to happen any time soon, I'm afraid.

 * Remove a lot of un-needed comments.
 * Don't put l_hotchar at the front of stuct linesw, there is no need to.
 * Use the #defines for the hotchar in the SLIP and PPP line disciplines

906f09bca4 Add a macro to accurately calculate the length of a struct ifreq when
it contains an address.  This can replace all the myriad (wrong) ways
in which this task is performed in the current system.  As an added
bonus, since it's a macro, then third-party software vendors have an easy
way to tell whether it's there or not.  (This will become necessary
when sizeof(struct sockaddr) is increaased, and also when additional
fields are added to struct ifreq.)

might be differences with INET disabled, but hardly anything compiled

easily) is sppp :-(

In sppp_chap_input:
1) in the CHAP_CHALLENGE case don't output the peer's name if it is not
what we expected (DEBUG) since it will be printed out in the course
of events anyway.
2) in the CHAP_SUCCESS case test whether the peer is required to
authenticate himself [(sp->lcp.opts & (1 << LCP_OPT_AUTH_PROTO))],
otherwise the state machine may never switch into the network state.
I saw this case against 2 different ISPs; they never bothered to
authenticate themselves to me.

it breaks K&R1 support and doesn't fix the pessimal type.

d7189ec67c Ooops, this should have made it into the same commit, but didn't.
Introduce the SIOC[SG]IFGENERIC hooks that can be used to pass an
arbritrary ioctl subcommand into an interface driver.  Surprisingly
enough, there was no provision for this already present (except of the
option of abusing SIOC[SG]IFMEDIA for this).

The idea is that an interface driver can establish ioctl subcommands
of its own that can't be meaningfully interpreted by the upper layer
interface ioctl function.  Something like this is required to
implement a clean solution of passing down things like CHAP secrets or
PPP options to the /sys/net/if_sppp* files.  (Yes, my CHAP is now
finally working with it, but i gotta update my kernel to the new
callout interface before being able to commit _that_.)
