* if stoeplitz is enabled, use it to provide a flowid for tcp packets.dlg2021-01-254-4/+29
| | | | | | | | | | | | | | drivers that implement rss and multiple rings depend on the symmetric toeplitz code, and use it to generate a key that decides with rx ring a packet lands on. if the toeplitz code is enabled, this diff has the pcb and tcp layer use the toeplitz code to generate a flowid for packets they send, which in turn is used to pick a tx ring. because the nic and the stack use the same key, the tx and rx sides end up with the same hash/flowid. at the very least this means that the same rx and tx queue pair on a particular nic are used for both sides of the connection. as the stack becomes more parallel, it will also help keep both sides of the tcp connection processing in the one place.
* use an intrmap when establishing interrupts for queues.dlg2021-01-251-21/+44
| | | | | | | mcx is still hardcoded/limited to 1 queue for now, but this lets different mcx devices use different cpus for handling packets. looks good jmatthew@

* vmm(4): wire faulted in pagesmlarkin2021-01-231-20/+6
| | | | | | | | | | | | | | | | | | | | This change wires the pages used by virtual machines managed by vmm(4). When uvm swaps out a page, vmm(4) does not properly do TLB flushing, possibly leading to memory corruption or improper page access later. While this diff is not the correct fix (implementing proper TLB flush semantics), it does work around the problem by not letting the pages get swapped out in the first place. This means that under memory pressure, swap pages will have to come from other processes, and it also means you cannot overcommit vmm(4) memory assignment (eg, assign more memory to VMs than you actually have). It is my plan to fix this the correct way, but that will take time. This issue was originally pointed out a long time ago by Maxime V., but due to my taking a year away from OpenBSD, the issue remained unfixed.

| | | | | | | | rdr-to, nat-to, af-to rules. The kernel uses the information from the packet description and fills it into the fields in the pflog header. While doing this, it is trival to figure out whether the packet has been rewritten. OK sashan@

* pflog(4) tried to log the translated packet with rdr-to, nat-to,bluhm2021-01-192-149/+5
| | | | | | | | | | | | | | and af-to addresses and ports applied. Therefore it created a mbuf chain on the stack with a partial copy. This is too complicated for IP options, extension header, NAT46 af-to, and fragmented mbuf chains. It even caused a crash in syzkaller. Usually the length checks in pf_setup_pdesc() rejected the faked mbuf and the goto copy logged the packet unmodified. Remove the pflog_mtap() function and call bpf_mtap_hdr() directly. As the old buggy code was bypassed in most cases, tcpdump(8) output of pflog does not change. Uncondionally log the unmodified packet.

* (re)Introduce locking for amaps & anons.mpi2021-01-198-98/+291
| | | | | | | | | | | | | | | A rwlock is attached to every amap and is shared with all its anon. The same lock will be used by multiple amaps if they have anons in common. This should be enough to get the upper part of the fault handler out of the KERNEL_LOCK() which seems to bring up to 20% improvements in builds. This is based/copied/adapted from the most recent work done in NetBSD which is an evolution of the precendent simple_lock scheme. Tested by many, thanks! ok kettenis@, mvs@
