* do not count ethernet header twice in if_obytes stats.damien2008-08-041-3/+3
| | | | | | | do not count address family field twice in tun's if_obytes stats. ok henning@ reyk@ deraadt@ for the ethernet bits. ok deraadt@ for the tun bits.
* Move the responsibility to free received packets on trunked interfacesmpf2008-06-131-5/+5
| | | | | from ether_input() into trunk_input() where it can be handled in a smarter way. OK claudio@ and reyk@ on an earlier version.

* A little bit of magic to make arp lookups work in MPLS as they should.claudio2008-05-091-2/+2
| | | | No need to preload the arp table anymore. hai norby@
* Prevent virtual interfaces from adding to the random pool.mpf2008-05-071-1/+8
| | | | | | | Also move the sampling into ether_input() where it can happen at the interrupt and not within splnet() processing, which might be less random. Discussed with mickey. OK markus@, mcbride@
* Import MPLS (Multi Protocol Label Switching)norby2008-04-231-1/+39
| | | | | | | | | | | | | MPLS support partly based on the (abandoned?) AYAME project. Basic LSR (Label Switch Router) functionality is present, but not fully functional yet. It is currently possible to insert entries in the LIB (Label Information Base) with route(8), but setting the operation type is not supported yet. Imported to allow more people to work on this in the coming weeks. ok claudio@ laurent@ dlg@
* extend the if_ethersubr.c crc functions to support updating a runningdjm2008-04-181-20/+23
| | | | | | | | | | | crc in addition to the existing "oneshot" mode and use them to replace ieee80211_crc_update() with the new ether_crc32_le_update(). Saves 1k kernel bss + some code. Mark the new ether_crc32_[lb]e_update functions as __pure for a ~25x speedup (on my i386 at least). feedback and ok damien@
* introduce mitigation for the calling of an interfaces start routine.dlg2008-04-101-3/+2
| | | | | | | | | | | | | | decent drivers prefer to have a lot of packets on the send queue so they can queue a lot of them up on the tx ring and then post them all in one big chunk. unfortunately our stack queues one packet onto the send queue and then calls the start handler immediately. this mitigates against that queue, send, queue, send behaviour by trying to call the start routine only once per softnet. now its queue, queue, queue, send. this is the result of a lot of discussion with claudio@ tested by many.

* Move carp load balancing (ARP/IP) to a simpler configuration scheme.mpf2008-02-051-5/+3
| | | | | | | | | | | | | | Instead of using the same IP on multiple interfaces, carp has to be configured with the new "carpnodes" and "balancing" options. # ifconfig carp0 carpnodes 1:0,2:100,3:100 balancing ip carpdev sis0 192.168.5.50 Please note, that this is a flag day for anyone using carp balancing. You'll need to adjust your configuration accordingly. Addititionally this diff adds IPv6 NDP balancing support. Tested and OK mcbride@, reyk@. Manpage help by jmc@.
* In ether_input() scheduling the soft interrupt and queueing thebluhm2008-01-171-10/+14
| | | | | | | | | | | | packet have to be protected by the same splnet. Otherwise on architectures where soft interrupts are executed immediately, the interrupt is processed before the packet is in the queue. On real hardware interfaces this was not a problem as ether_input() is called at splnet anyway. But when sending to a tun interface the packet got delayed. ok beck@ miod@ henning@ mpf@ markus@
* Factor out the virtual host portion of carp into a separate structmpf2007-11-221-6/+3
| | | | | | | | | | | | | | | | | | | | that is kept in a list per carp interface. This is the huge first step necessary to make carp load balancing nice and easy. One carp interface can now contain up to 32 virtual host instances. This doesn't do anything useful yet, but here is how an ifconfig for multiple entries now looks like: # ifconfig carp2 carpnodes 5:0,6:100 192.168.5.88 carp2: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500 lladdr 00:00:5e:00:01:05 carp: carpdev sis0 advbase 1 state MASTER vhid 5 advskew 0 state BACKUP vhid 6 advskew 100 groups: carp inet 192.168.5.88 netmask 0xffffff00 broadcast 192.168.5.255 OK mcbride@

| | | | | | | | | | #if NPF > 0 to prevent feeding back the mbuf do looutput if we are on simplex interfaces and the packet has been routed by pf, whch can lead to a loop in weird corner cases. apparently nobody triggered these cases in ages, since pf.h was not included and thus NPF not defined and thus this code not compiled. ok theo

* Add IP load balancing support for carp(4).mpf2007-03-181-6/+16
| | | | | | | | | | | | | This provides a similar functionality as ARP balancing, but also works for traffic that comes across routers. IPv6 is supported as well. The configuration scheme will change as soon we have sth better. Also add support for changing the MAC address on carp(4) interfaces. (code from mcbride) Tested by pyr@ and reyk@ OK mcbride@

* re-implement the bpf "filter drop" option that it actually works. thereyk2005-11-031-1/+9
| | | | | | | | | | | | | | | | bpf FILDROP interface exists for about one year but the required interface to the drivers was missing - so it was useless. this new approach based on a design by henning@ uses a new mbuf flag to mark filtered packets and to drop them in the generic network stack input routines (like ether_input). for example; after some additional testing, this could be used by dhclient to filter everything except DHCP packets (track tech@ for a corresponding dhclient diff). the "filter dropped" packets won't reach the network stack. so it's probably some kind of a very basic application layer packet filter ;). ok canacar@, discussed with henning@ and others
