2008-12-01A bit more cleanup.Brad Smith
ok mpf@
2008-11-30- Remove unused if_reset "bus reset routine" field in the ifnet struct.Brad Smith
- Add if_stop "stop routine" field in the ifnet struct. ok mglocker@
2008-11-28Eliminate the redundant bits of code for MTU and multicast handlingBrad Smith
from the individual drivers now that ether_ioctl() handles this. Shrinks the i386 kernels by.. RAMDISK - 2176 bytes RAMDISKB - 1504 bytes RAMDISKC - 736 bytes Tested by naddy@/okan@/sthen@/brad@/todd@/jmc@ and lots of users. Build tested on almost all archs by todd@/brad@ ok naddy@
2008-11-26Avoid network livelock.Theo de Raadt
Use a 1 tick timeout() to determine if the kernel even manages to get below softclock (from an old diff by mpf). If our timeout comes late, reduce the high water marks (to half) for all network interfaces, thus starving them of future packet allocations for their RX rings. For a few ticks longer, also block the high water marks from rising even if RX ring empty conditions would prod us to do so. Cards may start dropping some packets off the end of their smaller RX rings, but we were not able to do the work required in any case. With less interrupt time and mbuf movement, the system finds time to make progress at the network queues. Userland even gets to run. A x40 tuned to 600MHz shows no real reduction in performance. But a soekris has a working console now. ok dlg claudio, and art liked it too
2008-11-26dont have bpf.h expose the kernel ticks variable wherever it is includeing.David Gwynne
it is very confusing like this. ok deraadt@ canacar@
2008-11-26provide m_clsetlwm, an interface for an interface to raise its lowDavid Gwynne
watermark for mbuf cluster allocations. this is necessary for things like bge which cannot cope with less than a certain number of pkts on the ring. ok deraadt@
2008-11-25expect if_flags to have IFF_RUNNING rather than IFF_UP before modifyingDavid Gwynne
the per ifp cluster allocator. should prevent the hwm being raised innapropriately when a driver fills its rx ring for the first time.
2008-11-25art says he doesnt suck anymore, so enable the really big clusterDavid Gwynne
allocators again.
2008-11-25Factor increases are not needed, +1 appears to work as well.Theo de Raadt
ok dlg
2008-11-25m_cluncount() needs to walk the mbuf chain to correctly uncount all clustersClaudio Jeker
but don't do that in m_free() as that will cause a double loop behaviour when called via m_freem(). OK dlg@, deraadt@
2008-11-24Remove the IFF_OACTIVE dance in gif_start this is not needed because startClaudio Jeker
functions will never ever be called in parallel. dlg@ concured
2008-11-24move MCLPOOLS to if.h and force uipc_mbuf.c to get if.h, there is noTheo de Raadt
other option ok dlg
2008-11-24Fix splasserts seen in pr 5987 by propagating a flag that discribesMike Belopuhov
whether we're called from the interrupt context to the functions performing allocations. Looked at by mpf@ and henning@, tested by mpf@ and Antti Harri, the pr originator. ok tedu
2008-11-24add several backend pools to allocate mbufs clusters of various sizes outDavid Gwynne
of. currently limited to MCLBYTES (2048 bytes) and 4096 bytes until pools can allocate objects of sizes greater than PAGESIZE. this allows drivers to ask for "jumbo" packets to fill rx rings with. the second half of this change is per interface mbuf cluster allocator statistics. drivers can use the new interface (MCLGETI), which will use these stats to selectively fail allocations based on demand for mbufs. if the driver isnt rapidly consuming rx mbufs, we dont allow it to allocate many to put on its rx ring. drivers require modifications to take advantage of both the new allocation semantic and large clusters. this was written and developed with deraadt@ over the last two days ok deraadt@ claudio@
2008-11-24Implement link-state tracking on the routing table. Routes to interfacesClaudio Jeker
which are considered down will no be marked ~RTF_UP and so multipath routing will start to work as expected and not pump 50% of the traffic to nirvana. Most of the magic happens in rn_mpath_reprio() which fiddles with the routing table internals. The rest is more straight forward. get it in deraadt@
2008-11-23softraid support for ata over ethernet (aoe). this includes a client andTed Unangst
part of a server. there's no configuration yet, and several other drawbacks, but it can be hammered into shape. i haven't moved the code forward in a year, and marco wants it in the tree to hack on.
2008-11-22Allow rt_msg1() to get a NULL as struct rt_addrinfo this simplifies a fewClaudio Jeker
callers (plus an upcomming one). OK henning@, dlg@
2008-11-21Change rn_mpath_next() to be able to walk over the full multipath listClaudio Jeker
not only over routes of the same prio. This makes it possible to modify rt_mpath_matchgate() so that if only gateway is specified without a specific priority it will scan the full list and not only the first routes. This is also needed for upcoming link state tracking.
2008-11-16Make sure to increment the the output error counter ifBrad Smith
not using TRUNK_PROTO_NONE and there are no member ports. ok mpf@
2008-11-10Clear ifindex2ifnet[] in if_detach() this is needed because link localClaudio Jeker
addressing in IPv6 likes to do ifp = ifindex2ifnet[ifindex] without properly checking if the ifindex is valid. As a side-effect this solves parts of PR 5981. Debugged by jsing@. OK jsing@, deraadt@
2008-11-09Introduce bpf_mtap_ether(), which for the benefit of bpf listenersChristian Weisgerber
creates the VLAN encapsulation from the tag stored in the mbuf header. Idea from FreeBSD, input from claudio@ and canacar@. Switch all hardware VLAN enabled drivers to the new function. ok claudio@
2008-11-08Take into account that our ether_input() already strips theMarco Pfatschbacher
ethernet header. This lets us actually process the incoming LACP-Packets. It should now work with a lot more switches. At least a Catalyst 3500 seems happy. OK brad@

2008-11-06Introduced IPv6 support of uniform model for TTL handling.Michele Marchetto
OK claudio@ laurent@
2008-11-04Move the trunk port count check from trunk_lb_start() to trunk_start()Brad Smith
before the protocol start routine is called so as to cover all protocols with the same check. ok mpf@
2008-11-01Introduced Uniform Model for TTL handling.Michele Marchetto
MPLS TTL is mapped into network layer one as the packet exits the LSP. Just IPv4 support for now. Added the relevant sysctls to enable this behaviour. Input and OK claudio@
2008-10-30Fix building with !INET6 kernels.Brad Smith
2008-10-28Always skip "urpf-failed" test for IPv6 link local addresses.Marco Pfatschbacher
We could re-embed the scope-id before we do the route lookup, but then we would just find the very interface we've received the packet on anyway. OK markus@, claudio@, henning@
2008-10-28add support for multiple pflow(4) interfacesJoerg Goltermann
OK: claudio@ henning@
2008-10-28Remove return at the end of a void function.Brad Smith
2008-10-28In trunk_media_status() mark the interface as active if any ports areBrad Smith
active rather than just the primary being UP. From FreeBSD Ok mpf@

From FreeBSD Ok mpf@
2008-10-28Show the ACTIVE flag in ifconfig for the single interface that isBrad Smith
actually active in failover mode rather than all interfaces with a link. This makes it clear if the master interface is in use or one of the backup links. From FreeBSD Tested by jmc@ Ok mpf@
2008-10-28Added mpls_output() used to output mpls packets originating from local host.Michele Marchetto
Strictly similar to mpls_input(). Input and OK claudio@, OK laurent@
2008-10-24Allow the debug printf code which is trying to retreive the interfaceBrad Smith
pointer to get at the interface name by pointing to the correct struct.

2008-10-16Switch the existing TX VLAN hardware support over to having theChristian Weisgerber
tag in the header. Convert TX tagging in the drivers. Help and ok brad@
2008-10-16* Allow ether_input() and vlan_input() to handle incoming packetsChristian Weisgerber
where the tag is stored in the mbuf header. * Make bridge(4) handle interfaces with and without hardware tag support and forward packets inbetween. Help and ok claudio@
2008-10-16Drop promiscuously received packets if the vlan interface is not inChristian Weisgerber
promiscuous mode itself. Closes PR 5012. With claudio@. ok claudio@, henning@

interfaces attached to different networks can use the same session id. reported by gm_sjo <saqmaster at gmail dot com>
2008-10-15Second pass of simple timeout_add -> timeout_add_sec conversionsBret Lambert
This should take care of the simpler ones (i.e., timeout values of integer multiples of hz). ok krw@, art@
2008-10-14Now mpls_input() handles ipv4 and ipv6 explicit null labels.Michele Marchetto
Added mpe_input6 to manage also ipv6 packets insted of just ipv4 ones. OK claudio@ laurent@
