augustss 113024244c Make it compile in the absence of networks. Closes PR 14274 (mine). 2001-11-27 17:32:57 +00:00
martin 86c6c53869 Sanity check the tunnel route after computing it and don't mark the
interface up if there is no route or the route loops back to ourself.
This helps to avoid pilot errors which would result in kernel stack
overflows.

martin d1f0e4f6e4 Don't call if_alloc_sadl when creating the pppoe interface, it's called
from sppp_attach.
When destroying the interface, call sppp_detach for proper cleanup.
This avoids a crash from the slow timeout handler for no longer existing
interfaces (spotted by Rémi Zara).

onoe b7c46d6199 use ALIGNED_POINTER() instead of ALIGN().
The type of ALIGN() is vary on architecture and casting pointer to u_int
is incorrect for MI code.
Since the code is to make sure aligned access to IP header and requires
bcopy if the test fails.  So the performance implication is not necessary
and we can use ALIGNED_POINTER() here.

onoe b698d56d3c Move IBSS creation stuff from awi to ieee80211. 2001-09-20 13:54:43 +00:00
onoe aebd449baa Fix for FH infrastructure mode.
XXX: FH chanset should be calculated by FH hop pattern, but BayStack 650 AP
     always specify chanset to fixed value 1.  The previous code try to this
     hack into awi driver, but it is insufficient because the chanset value
     in awi driver may change while scan and it may be different from the
     value in receiving beacon/probe-response.  So we save encoded FH chanset
     into channel in 802.11 common bss information for now.
2001-09-19 04:09:54 +00:00
onoe 6a617566bc Move IEEE 802.11 MAC management functions from awi driver to
if_ieee80211subr.c, which can be shared between any IEEE 802.11
drivers.
However, most of current working IEEE 802.11b wireless LAN cards
have rich firmware and we cannot have a control to management frames
for such cards.

IBSS creation is now supported for the awi driver.

bjh21 5ddc1e1310 Add retry mechanisms for Econet, so that if a four-way handshake doesn't
complete for some reason, we defer it for a bit and then try again.  This
gets ping down to 0% packet loss.

Of course, ping _should_ have been at 0% packet loss anyway, and that's the
next thing to deal with.

thorpej d679590033 Split the pre-computed ifnet checksum flags into Tx and Rx directions.
Add capabilities bits that indicate an interface can only perform
in-bound TCPv4 or UDPv4 checksums.  There is at least one Gig-E chip
for which this is true (Level One LXT-1001), and this is also the
case for the Intel i82559 10/100 Ethernet chips.

bjh21 33d596bef8 Add support for incoming IP broadcast packets. The protocol for this is
worked out by observing RISC iX's behaviour, so it may be technically
wrong.  The only implementations of IP-over-Econet for which I've got
sources don't support broadcasts.

Tested using broadcast ping from RISC iX to NetBSD, and using rwhod.
2001-09-16 15:08:39 +00:00
bjh21 0f810d8948 eco_input():
Use m_copydata() to preserve the Econet header, so we don't depend on
  notionally-unused areas of an mbuf remaining untouched.
  Check that ARP-over-Econet requests are exactly eight bytes long.
  Use m_pullup() before trusting mtod().

Between them, these make reception of unicast ARP responses work properly.

bjh21 52b3d56b11 Add MI Econet support. This is lacking any interfaces to higher-layer
protocols, and lacking any timeouts, but it basically works, doing four-way
handshakes in both directions and incoming Machine Peek operations.

Oh, and Econet is Acorn's ancient, proprietary 500kbit/s networking
technology.

thorpej ca4d373730 Implement support for IP/TCP/UDP checksum offloading provided by
network interfaces.  This works by pre-computing the pseudo-header
checksum and caching it, delaying the actual checksum to ip_output()
if the hardware cannot perform the sum for us.  In-bound checksums
can either be fully-checked by hardware, or summed up for final
verification by software.  This method was modeled after how this
is done in FreeBSD, although the code is significantly different in
most places.

We don't delay checksums for IPv6/TCP, but we do take advantage of the
cached pseudo-header checksum.

Note: hardware-assisted checksumming defaults to "off".  It is
enabled with ifconfig(8).  See the manual page for details.

Implement hardware-assisted checksumming on the DP83820 Gigabit Ethernet,
3c90xB/3c90xC 10/100 Ethernet, and Alteon Tigon/Tigon2 Gigabit Ethernet.
