| | | | | | | this is a bit funky cos we give up the ref while sleeping in tunread, and have to get a new ref on wakeup. ok claudio@

* Remove splassert(IPL_NET) from if_input().mpi2015-07-201-4/+1
| | | | | | | | | | | if_input() has been designed to be able to safely handle a batch of packets from physical drivers to the network stack. Most of these drivers have an interrupt routine executed at IPL_NET and the check made sense during the conversion. However we also want to re-enqueue packets with if_input() from the network stack currently running at IPL_SOFTNET. ok claudio@

* Store a unique ID, an interface index, rather than a pointer to thempi2015-06-161-2/+2
| | | | | | | | | | | | | | | receiving interface in the packet header of every mbuf. The interface pointer should now be retrieved when necessary with if_get(). If a NULL pointer is returned by if_get(), the interface has probably been destroy/removed and the mbuf should be freed. Such mechanism will simplify garbage collection of mbufs and limit problems with dangling ifp pointers. Tested by jmatthew@ and krw@, discussed with many. ok mikeb@, bluhm@, dlg@

* replace the use of ifqueues for most input queues serviced by netisrdlg2015-04-101-14/+5
| | | | | | | | | | | | | | | | | with niqueues. this change is so big because there's a lot of code that takes pointers to different input queues (eg, ether_input picks between ipv4, ipv6, pppoe, arp, and mpls input queues) and falls through to code to enqueue packets against the pointer. if i changed only one of the input queues id have to add sepearate code paths, one for ifqueues and one for niqueues in each of these places by flipping all these input queues at once i can keep the currently common code common. testing by mpi@ sthen@ and rafael zalamena ok mpi@ sthen@ claudio@ henning@

* remove the congestion handling from struct ifqueue.dlg2015-03-181-3/+2
| | | | | | | | | | | | | | | | | its only used for the ip and ip6 network stack input queues, so it seems unfair that every instance of ifqueue has to carry a pointer around for this specific use case. this moves the congestion marker to a kernel global. if we detect that we're congested, we assume the whole system is busy and punish all input queues. marking a system as congested is done by setting the global to the current value of ticks. as the system moves away from that value, it moves away from being congested until the comparison fails. written at s2k15 ok henning@ beck@ bluhm@ claudio@

* First step towards making uiomove() take a size_t size argument:miod2015-02-101-3/+3
| | | | | | | - rename uiomove() to uiomovei() and update all its users. - introduce uiomove(), which is similar to uiomovei() but with a size_t. - rewrite uiomovei() as an uiomove() wrapper. ok kettenis@

* "struct pkthdr" holds a routing table ID, not a routing domain one.mpi2014-04-141-2/+2
| | | | | | | | | | | | | | Avoid the confusion by using an appropriate name for the variable. Note that since routing domain IDs are a subset of the set of routing table IDs, the following idiom is correct: rtableid = rdomain But to get the routing domain ID corresponding to a given routing table ID, you must call rtable_l2(9). claudio@ likes it, ok mikeb@
