2002-02-14If helps to loop over the correct variable *sigh*Jason Wright
2002-02-07bridge_output() needs a forcibly aligned copy just like bridge_broadcast()Jason Wright
because of calls it makes to altq; thanks to art for testing and kjc for pointing that I forgot this case.
2002-01-02Don't forget to deallocate on failure.Jason Wright
2002-01-01This is ugly: make a specialized deep copy in bridge_broadcast() thatJason Wright
ensures that the payload after the ethernet header is nicely aligned (basically this is two copies, one for the ethernet header and one for the payload) and glue the two copies together. bridge_filter() assumes it has been handed a nicely aligned packet. This should address pr#2248.
2001-12-15add support for creating span ports so that one can snoop a bridgeJason Wright
from another interface/machine/network.
2001-12-13remove redundant #if NPF. ok jason@jasoni
2001-12-10update ip stats when dropping an ip packetjasoni
ok jason@
2001-12-08mflags and len were uninitialized in bridge_broadcast (source of someJason Wright
accounting errors me thinks).
2001-11-26add fastroute options similar to what is found in ipfjasoni

2001-07-27PF_IN/PF_OUT aren't defined if NPF <= 0, deal with it.Jason Wright
2001-07-25Make sure pkthdr.rcvif is correct before calling pf_test()Jason Wright
2001-07-25- unconditionalize call to bridge_input() (fewer #ifdef's and NPF>0 is ↵Jason Wright
default case anyway). - add support for filtering on interface output (and call pf_test() appropriately) What all this means: nonstateful and stateful PF filtering now works with the bridge.
2001-07-17split ip normalization out into a separate file, okay dhartmei@Niels Provos

2001-06-27IPFILTER->NPFAngelos D. Keromytis
2001-06-27introduce the ALTQ queue macros into sys/net files.Kenjiro Cho
the new model removes direct references to the fields in ifp->if_snd, and defines the following macros to manipulate ifp->if_snd. IFQ_ENQUEUE(ifq, m, pktattr, err) IFQ_DEQUEUE(ifq, m) IFQ_POLL(ifq, m) IFQ_PURGE(ifq) IFQ_IS_EMPTY(ifq) the new model also enforces some rules regarding how to use these macros. details are descrined in http://www.csl.sony.co.jp/~kjc/software/altq-new-design.txt

2001-06-15change the meaning of ifnet.if_lastchange to meet RFC1573 ifLastChange.Jun-ichiro itojun Hagino
follows BSD/OS practice and ucd-snmp code (FreeBSD does it for specific interfaces only). was: if_lastchange get updated on every packet transmission/receipt. now: if_lastchange get updated when IFF_UP is changed.
2001-06-07use faster arc4random() instead of get_random_bytes(); jason@ okMichael Shalayeff
2001-06-06in bridge_filter(), pullup hlen, not sizeof(struct ip); ok jason@jasoni
2001-06-01Don't let packets that need IPsec crypto processing at the NIC beAngelos D. Keromytis
bridge-broadcast; rather, turn off offloading for now. The IPsec stack will do its own crypto for subsequent packets, which will be broadcast. Once the bridge knows which interface to send packets for that MAC to, if that interface supports IPsec offloading it'll turn it back on.
2001-05-30Remove ipf. Darren Reed has interpreted his (old, new, whichever)Theo de Raadt
licence in a way that makes ipf not free according to the rules we established over 5 years ago, at www.openbsd.org/goals.html (and those same basic rules govern the other *BSD projects too). Specifically, Darren says that modified versions are not permitted. But software which OpenBSD uses and redistributes must be free to all (be they people or companies), for any purpose they wish to use it, including modification, use, peeing on, or even integration into baby mulching machines or atomic bombs to be dropped on Australia. Furthermore, we know of a number of companies using ipf with modification like us, who are now in the same situation, and we hope that some of them will work with us to fill this gap that now exists in OpenBSD (temporarily, we hope).
2001-05-11check for 'fastroute' condition (like ip_input) in bridge_filter() andJason Wright
deal with it.

2001-02-06allow for configuring number of bridge ifaces in ukc; jason@ ok and helpMichael Shalayeff
2001-02-04For unicast packets destined for the bridge machine itself, learn from theJason Wright
SRC address (not the DST).
2001-02-02In the broadcast received on gif case, throw the packet up the stack ifJason Wright
we -found- an appropriate interface.
2001-02-01packets received on gif's for local processing can't just fall down theJason Wright
stack, they have to be pushed; when calling ether_input(): 1 - unicast packets have the ifp of the matching interface 2 - bcast/mcast packets have the ifp of the first IFT_ETHER bridge member based on discussion with angelos.
2001-01-30change ip_compat.h to ip_fil_compat.h for clarity. Impending ipf mergeKjell Wooding
2001-01-17IPF 3.4.15. (IPv6 not working yet).Federico G. Schwindt
Note: before building the userland part you need to do make includes.
2000-12-30For bridged IPsec, use the gif* interfaces.Angelos D. Keromytis
2000-12-12Add support for 802.1D spanning tree protocol.Jason Wright
NOTE: this requires recompiling brconfig with updated include files.

fails.. it's still ENOMEM.
