2021-02-21No need for state_preboot() to double check timeout beingkrw1-13/+3
tracked in tick_msg() and explicitly calling tick_msg(TICK_SLEEP). One fewer use of each of time(), ifi->startup_time and config->link_timeout. Makes code easier to follow. No intentional functional change.

2021-02-21cut nvgre(4) over to use common etherbridge code.dlg2-317/+129
the "ports" that nvgre provides to etherbridge are ip addresses used in the underlay network. ok patrick@ jmatthew@
2021-02-21cut bpe(4) over to using the common etherbridge code.dlg2-292/+127
it's pretty straightforward since etherbridge was mostly based on this code in the first place. the etherbridge_ops that bpe provides to etherbridge set entries up to point at mac addresses in the underlay network. ok patrick@ jmatthew@
2021-02-21add etherbridge, the guts of a learning bridge that can be reused.dlg3-2/+693
this allows for the factoring out of the learning bridge code i wrote in bpe and nvme, and should be reusable for other drivers needing a mac learning bridge. the core data structures are an etherbridge struct to represent the learning bridge, eb_entry structs for each mac address entry that the bridge knows about, and an etherbridge_ops struct that drivers fill in so that they can use this code. eb_entry structs are stored in a hash table made up of SMR_TAILQs to support lookups of entries quickly and concurrently in the forwarding path. they are also stored in a locked red-black tree to help manage the uniqueness of the mac address in the table. the etherbridge_ops handlers mostly deal with comparing and testing the "ports" associated with mac address table entries. the "port" that a mac address entry is associated with is opaque to the etherbridge code, which allows for this code to be used by nvgre and bpe which map mac addresses inside the bridge to addresses in their underlay networks. it also supports traditional bridges where "ports" are actual interfaces. ok patrick@ jmatthew@

2021-02-20Return a min/max version of zero if set to zero.jsing3-17/+41
OpenSSL's SSL{_CTX,}_get_{min,max}_proto_version() return a version of zero if the minimum or maximum has been set to zero (which means the minimum or maximum version supported by the method). Previously we returned the minimum or maximum version supported by the method, instead of zero. Match OpenSSL's behaviour by using shadow variables. Discussed with tb@

2021-02-20move from calling l3 protocol input handlers to using if_vinput.dlg2-40/+14
if_vinput requires mpsafe interface counters, so add those in. this factors out some more code between drivers. monitor mode will work on these interfaces now too.
2021-02-20move gre and mgre from calling l3 input handlers to using if_vinput.dlg1-46/+11
using if_vinput factors out a lot of repeated code between tunnel drivers, and it means monitor mode works on gre and mgre now too. make the l2 gre interfaces do some things in the same order while here.
2021-02-20move gif from calling l3 protocol input handlers to using if_vinput.dlg1-25/+5
if_vinput requires mpsafe interface counters, so gif is a bit more mpsafe now than it was before. using if_vinput means monitor mode works on gif now too.
2021-02-20add p2p_input, like ether_input but for l3 tunnel interfaces.dlg2-2/+44
the l3 protocol input to push the packet is based on a value in m->m_pkthdr.ph_family, which tunnel drivers should set before calling if_vinput. add p2p_bpf_mtap to call bpf_mtap_af also using m->m_pkthdr.ph_family.
2021-02-20let tun use bpf_mtap for handling input packets.dlg1-1/+4
tun (not tap) input packets are written from userland in the same format that it's bpf dlt is expecting, so we can push the packet straight into bpf with bpf_mtap. this is more correct that using bpf_mtap_ether for tun.
2021-02-20default interfaces to bpf_mtap_ether for their if_bpf_mtap handler.dlg2-4/+8
call (*ifp->if_bpf_mtap) instead of bpf_mtap_ether in ifiq_input and if_vinput.
2021-02-20give interfaces an if_bpf_mtap handler.dlg1-1/+2
the network stack is now responsible for calling bpf for packets that the interface receives, and we so far got away with using bpf_mtap_ether for everything. this doesn't work if layer 3 input goes through the same functions, so letting drivers specify the appropriate bpf mtap function means they will be able to cope.

ok benno@
2021-02-20add a MONITOR flag to ifaces to say they're only used for watching packets.dlg3-8/+12
an example use of this is when you have a span port on a switch and you want to be able to see the packets coming out of it with tcpdump, but do not want these packets to enter the network stack for processing. this is particularly important if the span port is pushing a copy of any packets related to the machine doing the monitoring as it will confuse pf states and the stack. ok benno@

Occasionally one might read a manual page in a webbrowser, e.g. "MANPAGER=firefox man -T html jq", however temporary files created for pagers lack file extensions and most web browsers are unable to detect a file's content without it. Special case mandoc(1)'s HTML output format by appending the ".html" suffix to file names such that browsers will actually render HTML as such instead of showing it as plain text. Input schwarze
