2014-06-13Instead of updating all the cluster allocation water marks of all theMartin Pieuchot
interfaces when the kernel is livelocked, only do it for the current pool and defer the other updates. This allow us to get rid of an interface list iteration in a critical path. Ridding the libc crank since this change introduce an ABI break. ok claudio@
2013-11-21split kernel parts of the if.h into a separate header file if_var.hMike Belopuhov
which allows us to modify ifnet structure in a relatively safe way; discussed with deraadt, ok mpi
2013-11-09ticks is compared against mcl_grown to see if time has elapsed sinceDavid Gwynne
the rx ring was last allowed to grow and then assigned to it. it is erroneous to do this because mcl_grown is a u_int and ticks is an int. this makes mcl_grown an int, and follows the idiom in kern_timeout.c of going "thing - ticks < diff", which better copes with ticks wrapping around and being used to calculate relative intervals. ok pirofti@ guenther@

2013-10-13Import vxlan(4), the virtual extensible local area network tunnelReyk Floeter
interface. VXLAN is a UDP-based tunnelling protocol for overlaying virtualized layer 2 networks over layer 3 networks. The implementation is based on draft-mahalingam-dutt-dcops-vxlan-04 and has been tested with other implementations in the wild. put it in deraadt@
2013-10-12new bandwidth shaping subsystem, kernel sideHenning Brauer
uses hfsc behind the scenes; altq stays in parallel for a migration phase. if.h even more messy for the transition, but eventuelly it should become readable... looked over & tested by many, ok phessler sthen
2013-09-17Change vlan(4) detach procedure to not use a hook but a list of vlansMartin Pieuchot
on the parent interface. This is similar to what bridge(4), trunk(4) or carp(4) are doing and allows us to get rid of the detachhook. ok reyk@, mikeb@

structure rather than doing various M_WAITOK allocations during the *attach() functions, we always rely on them anyway. ok mikeb@, uebayasi@
2013-04-02Instead of storing the link-level address of every interface in a globalMartin Pieuchot

a gruesome union, to block the compiler from placing the struct incorrectly aligned on stack frames ok guenther
2012-10-05Point an interface directly to its bridgeport configuration, insteadCamiel Dobbelaar
of to the bridge itself. This is ok, since an interface can only be part of one bridge, and the parent bridge is easy to find from the bridgeport. This way we can get rid of a lot of list walks, improving performance and shortening the code. ok henning stsp sthen reyk
2012-09-19defina an IFCAP_CSUM_MASK, covering IFCAP_CSUM_*, and use it in if_vlan.cHenning Brauer
to replace the list of them. this actually makes vlan inherit the IPv6 CSUM flags from it's parent, that had been commented out since this code was committed back in 2001. ok benno mpf

2012-08-21Reverse the name and meaning of the IFXF_INET6_PRIVACY interfaceAlexander Bluhm
flag. It is now called IFXF_INET6_NOPRIVACY. So IPv6 privacy addresses are on by default without resetting the flag during ifconfig down/up. OK stsp@, sperreault@ (who wrote the same diff)

unfortunately altq is one giant namespace violation. rename just those that conflict with new stuff for now only to be found on my laptop. reduce pain, the diff is huge already. ok ryan

2011-07-03LINK_STATE_IS_UP() should consider LINK_STATE_UNKNOWN as an up state.Claudio Jeker
This is now possible because carp no longer uses LINK_STATE_UNKNOWN for a state that is considered down. This will simplify a lot of code. OK mpf@ mcbride@ henning@

2010-09-23tweak the mclgeti algorithm to behave better under load.David Gwynne
instead of letting hardware rings grow on every interrupt, restrict it so it can only grow once per softclock tick. we can only punish the rings on softclock ticks, so it make sense to only grow on softclock tick boundaries too. the rings are now punished after >1 lost softclock tick rather than >2. mclgeti is now more aggressive at detecting livelock. the rings get punished by an 8th, rather than by half. we now allow the rings to be punished again even if the system is already considered in livelock. without this diff a livelocked system will have its rx ring sizes scale up and down very rapidly, while holding the rings low for too long. this affected throughput significantly. discussed and tested heavily at j2k10. there are still some games with softnet we can play, but this is a good first step. "put it in" and ok deraadt@ ok claudio@ krw@ henning@ mcbride@ if we find out that it sucks we can pull it out again later. till then we'll run with it and see how it goes.

2010-06-26Implement a simple keepalive mechanism in gre(4) that is compatible withClaudio Jeker
the one used by Cisco. It sends a return gre packet inside a gre packet to the other side and expects it to return. OK deraadt, reyk additional testing by sthen
2010-05-28Rework the way we handle MPLS in the kernel. Instead of fumbling MPLS intoClaudio Jeker
ether_output() and later on other L2 output functions use a trick and over- load the ifp->if_output() function pointer on MPLS enabled interfaces to go through mpls_output() which will then call the link level output function. By setting IFXF_MPLS on an interface the output pointers are switched. This now allows to cleanup the MPLS input and output pathes and fix mpe(4) so that the MPLS code now actually works for both P and PE systems. Tested by myself and michele (A custom kernel with MPLS and mpe enabled is still needed).

2010-04-06Simple implementation of RFC4941, "Privacy Extensions for StatelessStefan Sperling
Address Autoconfiguration in IPv6". For those among us who are paranoid about broadcasting their MAC address to the IPv6 internet. Man page help from jmc, testing by weerd, arc4random API hints from djm. ok deraadt, claudio
2010-01-13maintain a global RB tree of all local addresses in the system. thisHenning Brauer
includes AF_LINK addresses (aka mac addresses in the ethernet case). for inet this also includes the broadcast addresses. depends on ifinit() called earlier so we have a chance to pool_init before autoconf assigns the AF_LINK addresses, the v6 fix, and the ifa_add/del abstraction i just committed. this is a change in semantics, it is now illegal to change the actual address in an ifaddr struct because then the RB tree becomes unbalanced. nothing using this tree yet. ok theo ryan dlg
2010-01-13instead of fiddling with the per-interface address lists directly inHenning Brauer
many places create a proper API (ifa_add / ifa_del) and use it. ok theo ryan dlg

the route messages so that people and compilers will not get confused. ok claudio
2009-09-17Remove the comaptibility structures for routing socket version 3.Claudio Jeker
The RTM_VERSION bump is 2 years ago and so there is no need for this. Diff made by tedu@ some time ago but got never commited so I do it now.
2009-09-14Add a way to convert the ifi_link_state to a string without the use ofClaudio Jeker
if_media. This makes link state tracking a lot easier as there is no need to convert if types to if_media types, etc. Additionally this allows us to extend the link states to include states tracked on higher protocol layers. gre(4) keepalives packets, bfd and udld can be implemented without ugly hacks. OK henning, michele, sthen, deraadt
2009-08-10At sys_reboot time, bring all the interfaces down so that their xxstopTheo de Raadt
functions are called, which will turn off DMA. Receiving packets into your memory after a system reboot is pretty nasty. This will also mean that the shutdown hooks can go; this solution is smaller. ok henning miod dlg kettenis

2009-06-05Initial support for routing domains. This allows to bind interfaces toClaudio Jeker
alternate routing table and separate them from other interfaces in distinct routing tables. The same network can now be used in any doamin at the same time without causing conflicts. This diff is mostly mechanical and adds the necessary rdomain checks accross net and netinet. L2 and IPv4 are mostly covered still missing pf and IPv6. input and tested by jsg@, phessler@ and reyk@.

2009-06-04allow IPvShit to be turned off completely per-interface.Henning Brauer
