43e8def200 Implement TUN[GS]IFHEAD ioctls. Passing a non-zero int to TUNSIFHEAD
tells that tun unit to prepend a four byte address family to packets
queued for tunread() and to expect a four byte address family at the
front of data received by tunwrite().

We queue any protocol received from the interface for tunread(), but
only accept INET, INET6, IPX and NETATALK from tunwrite().  There is
support for Xerox's NS stuff, but AFAICT config(8) doesn't ever
define NS.

eba2a1aeb9 |The hard limit for the BPF buffer size is 32KB, which appears too low
|for high speed networks (even at 100Mbit/s this corresponds to 1/300th
|of a second). The default buffer size is 4KB, but libpcap and ipfilter
|both override this (using the BIOCSBLEN ioctl) and allocate 32KB.
|
|The following patch adds an sysctl for bpf_maxbufsize, similar to the
|one for bpf_bufsize that you added back in December 1995. I choose to
|make the default for this limit 512KB (the value suggested by NFR).

66810dd0c3 Clear ro->ro_rt just after RTFREE().
Pleases let me make sure that no one touch the invalid ro_rt pointer,
  after splx(s) and before next ro_rt initialization.
  Though usually this seems to be already called at splnet,
  I still sometime experience kernel crash at rtfree() in my
  INET6 enabled environment where IPv6 connection is frequently used.
  (Off-course, it might be just due to another bug.)

a0067d7b89 Attempt to fix a problem with receiving packets on USB ethernet interfaces.
Packets are received inside USB bulk transfer callbacks, which run at
splusb() (actually splbio()). The packet input queues are meant to be
manipulated at splimp(). However the locking apparently breaks down under
certain circumstances and the input queues can get trampled.

There's a similar problem with if_ppp, which is driven by hardware/tty
interrupts from the serial driver, but which must also manipulate the
packet input queues at splimp(). The fix there is to use a netisr, and
that's the fix I used here. (I can hear you groaning back there. Hush up.)

The usb_ethersubr module maintains a single queue of its own. When a
packet is received in the USB callback routine, it's placed on this
queue with usb_ether_input(). This routine also schedules a soft net
interrupt with schednetisr(). The ISR routine then runs later, at
splnet, outside of the USB callback/interrupt context, and passes the
packet to ether_input(), hopefully in a safe manner.

The reason this is implemented as a separate module is that there are
a limited number of NETISRs that we can use, and snarfing one up for
each driver that needs it is wasteful (there will be three once I get
the CATC driver done). It also reduces code duplication to a certain
small extent. Unfortunately, it also needs to be linked in with the
usb.ko module in order for the USB ethernet drivers to share it.

Also removed some uneeded includes from if_aue.c and if_kue.c

5500d3bedf Two more fixes to if_detach. These are generic to all interfaces and
do not pollute the interface further.

o Run if_detach at splnet().
o Creatively swipe the relevant parts of the netatm atm_nif_detach

aa6be122fd Add some gross ad-hock hacks to increase stability of if_detach:
o be more careful about clearing addresses (this isn't a kludge)
o For AF_INET interfaces, call SIOCDIFFADDR to remove last(?) bit
  of cruft.

Special cases for AF_INET shouldn't be here, but I didn't see a good
generic way of doing this.  If I missed something, please let me know.

This gross hack makes pccard ejection stable for ethernet cards.

68f956b85e Fix a route table leak in rtalloc() and rtalloc_ign(). It is
possible for ro->ro_rt to be non-NULL even though the RTF_UP flag
is cleared.  (Example: a routing daemon or the "route" command
deletes a cloned route in active use by a TCP connection.)  In that
case, the code was clobbering a reference to the routing table
entry without decrementing the entry's reference count.

The splnet() call probably isn't needed, but I haven't been able
to prove that yet.  It isn't significant from a performance standpoint
since it is executed very rarely.

f8307e1233 Add two new generic control messages, NGM_ASCII2BINARY and
NGM_BINARY2ASCII, which convert control messages to ASCII and back.
This allows control messages to be sent and received in ASCII form
using ngctl(8), which makes ngctl a lot more useful.

This also allows all the type-specific debugging code in libnetgraph
to go away -- instead, we just ask the node itself to do the ASCII
translation for us.

Currently, all generic control messages are supported, as well as
messages associated with the following node types: async, cisco,
ksocket, and ppp.

See /usr/share/examples/netgraph/ngctl for an example of using this.

Also give ngctl(8) the ability to print out incoming data and
control messages at any time.  Eventually nghook(8) may be subsumed.

Several other misc. bug fixes.

a86ab8174f Only emit the ``wrong ifa'' message if the matching interface
is neither IFF_LOOPBACK or IFF_POINTOPOINT.  It's quite common
(and probably more correct) to route local IP numbers via lo0
and it makes configuration easier to assign the hostname address
to local POINTOPOINT links too.

This message usually remains hidden because the loopback interface
gets the highest interface number at boot time, but when the
ethernet interface is added later, the message can get pretty
annoying.

Also, fix a typo.
