2009-02-03Use our own flags to set the operations and not RTF_PROTOX.Michele Marchetto
Switch the padding field into a MPLS one in rt_msghdr to store relevant informations. OK claudio@ laurent@
2009-01-31u_char is not compatible with default argument promotion type thusAlexander Yurchenko
can't be used with va_start. change it to u_int. ok miod@
2009-01-31No need to invent another _offset, just use the one from param.h.Alexander Yurchenko
As a bonus it eliminates casting from pointer to int. ok miod@ tedu@ millert@
2009-01-31unbreak ! INET6 case by sprinking #ifdef INET6Henning Brauer
noticed by Vladimir Kirillov <proger@uaoug.org.ua>
2009-01-30sync the part copied from ip_output: always initialize IP checksumChristian Weisgerber
to zero for checksum offload; ok henning@
2009-01-30sprinkle splassert(IPL_SOFTNET) around the code that inserts, unlinks, andDavid Gwynne
frees pf states. ok mcbride@
2009-01-29Split the address selection from pools away from pf.c and put it inPierre-Yves Ritschard
pf_lb.c. This will ease the process of adding more selection types without bloatening pf.c even more. ok and a weird death threat, henning@ raised eyebrow, dlg@
2009-01-29move some code around in preparation for future work:Henning Brauer
break out the code that doesn't deal with fragment reassembly and only modifies stuff in the ip header to their own functions. pass them what they need instead of making them get the info from a rule ptr. ok dlg ryan
2009-01-29Fix a crash found by bluhm@ in rn_mpath_reprio(). The rn_mklist handling wasClaudio Jeker
wrong which resulted in a NULL rm_leaf which caussed a NULL deref a bit later. Check against the right route nodes to figure out if the rm_leaf needs to be updated. Tested by bluhm@, OK dlg@
2009-01-28Get rid of the ugly rtentry hack.Michele Marchetto
We can now act as edge node and allow ipv4 packets to enter a Label Switched Path and not just forwarding MPLS packets. OK claudio@
2009-01-28Implement basic routing socket filtering. It is possible to give a list --Claudio Jeker
actually a bitfield -- of routing messages a listener is interested in. This list can be changed with a setsockopt(s, AF_ROUTE, ROUTE_MSGFILTER, ...) call. OK henning@, dlg@
2009-01-27If a packet translation was a NOP, undo separate NAT key andMarco Pfatschbacher
pretend there was no match. This prevents pf_state_insert() to fail with duplicate keys. OK henning@, mcbride@
2009-01-27handle HW VLAN tags being passed down; from BradChristian Weisgerber
2009-01-27include the VLAN priority for hardware tagging, too; ok claudio@Christian Weisgerber
2009-01-27make the hardware/no hardware tag stripping cases consistent and don'tChristian Weisgerber
hash the VLAN priority; ok henning@
2009-01-27make drivers tell the mclgeti allocator what their maximum ring size isDavid Gwynne
to prevent the hwm growing beyond that. this allows the livelock mitigation to do something where the hwm used to grow beyond twice the rx rings size. ok kettenis@ claudio@
2009-01-16In pf_test_rule(), if we don't create a state, free any state keys thatDavid Krause
may have been allocated earlier by pf_get_translation(). Fixes a pf_state_key_pl leak triggered by certain ICMP types matching a NAT rule. Finally located with the help of pool_walk(). ok henning@ dlg@ mcbride@
2009-01-09fix egress group matching for IPv6; ok claudio@David Krause
2009-01-08Fix sockaddr_mpls structure.Michele Marchetto
Now it contains just the label as it must be. This introduces a ugly hack in rtentry that will be removed as soon as possible. OK claudio@
2009-01-06Always check rs_malloc() returns. Also add M_ZERO and M_CANFAILThordur I. Bjornsson
to the flags passed to malloc() in the kernel case since we always zero the memory and are able to fail gracefully. remove memset()'s and bzero's accordingly and use calloc(1, ...) in the userland case so we get it zeroed. OK henning@, claudio@
2009-01-06Change the way way rn_mklists work (especially the RNF_NORMAL ones).Claudio Jeker
Until now RNF_NORMAL masks did not use the refcount because only one route in a particular subtree could have this mask. With multipath routing this is no longer correct. The result was wrong backtracking information beeing stored in the radix tree and so cretain lookups ended up on the wrong multipath nodes. Use rm_refs for RNF_NORMAL masks so that all multipath routes are able to point to the same radix_mask entry. Additional logic ensures that rm_leaf always points back to the head of the multipath rn_dupedkey chain. Tested by dlg@, gollo@, david@, sthen@ and a few more This can have my OK dlg@
2009-01-06Send broadcast and multicast traffic not only out on all bridge interfaces butClaudio Jeker
also up into the network stack on all interfaces. Multicast addresses are bound to interfaces and without this local sockets did not see packets that entered the bridge on a different interface. This should help IPv6. OK naddy@
2009-01-03sync flow sequence ids on all used pflow interfaces.Joerg Goltermann
OK henning@
2009-01-03Write back the priority the kernel used. Fixes a problem seen in ospfd whenClaudio Jeker
routes are added via route(8) -- those where added with the wrong priority and so where not correctly tracked later on. Found and tested by gollo@
2008-12-29At least try to make this code a bit easier to read. Don't fiddle with xClaudio Jeker
when xx can do the trick or in dlg's words: "xx was a copy of x so they could use x for some temp working and restore it from xx later? yeesh" ok dlg@
2008-12-29Use rn_mpath_next() in rtalloc_mpath() to figure out if the next routeClaudio Jeker
belongs to the same multipath group instead of own wrong check which failed to look at the priority. Found and diff tested by gollo@
2008-12-22Change DLT_MPLS number.Michele Marchetto
Use one assigned by tcpdump guys to keep things in sync with them. ok canacar@
2008-12-21split the pfsync input routine up so that each action has its own functionDavid Gwynne
to handle it. this is to modularise it in preparation for further changes. in my opinion it also makes the code a lot easier to read and to maintain. tested by sthen@ johan@
2008-12-18Remove redundant function prototypes which are already in pfvar.hDavid Hill
ok henning@
2008-12-14Allow trunk_hashmbuf() to take HW VLAN tagging into consideration.Brad Smith
ok mpf@ naddy@
2008-12-14Since trunk_hashmbuf() and thus trunk_lb_gethdr() are no longer specificBrad Smith
to the loadbalance code rename trunk_lb_gethdr() to just trunk_gethr(). ok mpf@
2008-12-12Introduce a if_priority that will be added to RTP_STATIC when routes areClaudio Jeker
added without an expilict priority. This allows to specify less prefered interfaces that will only take over if the primary interface loses link. OK deraadt@
2008-12-12Make sure that incomming routing messages don't have RTP_DOWN set. MaskClaudio Jeker
the rtm_priority with RTP_MASK so that userland (e.g. arp) can issue a RTM_GET and reissue the message as RTM_DELETE.
2008-12-11export per-interface mbuf cluster pool use statistics out to userlandTheo de Raadt
inside if_data, so that netstat(1) and systat(1) can see them ok dlg
2008-12-05add ethertype and tcpdump support for VLAN stacking (QinQ) withStuart Henderson
type number 0x88a8 specified by 802.1ad. from reyk on misc@. "ok, go for it" dlg
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@
