ddb(4): clean up callout command - display timeouts in the thread work queue, if any - identify timeouts in the thread/softint work queue as such - if not in work queue, print - print arg pointer by hand to ensure consistent length for all pointers on both 32 and 64-bit platforms - generally make sure columns are correctly aligned and spaced ok mpi@ visa@ |

default (ie, reset) the partner info when a ports link goes down. this doesnt seem to be mentioned in the spec, but is a sensible thing to do if you think about it. all the switches i've tried also do this, so there's some consensus about it being sensible. this is done in the link state handler rather than being added to one of the state machines. the idea is to keep the state machines as close to what's in the spec as possible. |

try to notify the partner when the port is going away or down. by notify i mean we send an lacp packet with our collecting and distributing flags cleared, which should tell the remote system that it should no longer handle packets on their port as part of their aggregation. this is implemented by "unselecting" a port. if an active port is going away, ie, being removed from an aggr via "ifconfig aggr0 -trunkport port0", all that happens is software state on our side changes and we stop considering the interface as part of the aggr interface. the partner system is otherwise oblivious and can continue to send us packets until its expiry timeout fires because it doesn't know any better. we already intercept a ports ioctl handling, so if someone goes "ifconfig portX down" while it is attached to an aggr, we can catch that before the underlying driver actually tears the rings down, and we still have a chance to try and send a packet to the peer. this is useful because our drivers generally do not drop the physical link, so again, the partner system is oblivious to the change on our side until its expiry timer fires. expiry timeouts can be up to 90 seconds away, which is a lot of traffic to blackhole. sending the notification to the parnter means they withdraw this link at the same time the local system is pulling the port out of the aggregation. hopefully. it is possible the packet is lost, but this is a good start. the only caveat to this is is my implementation ignores the transmit state machine from the lacp spec, and may cause more than 3 lacp packets per second to be transmitted to the partner system. oh well. i should look at the marker protocol too. |

After the kernel has reached the sysclt kern.maxclusters limit, operations get stuck while holding the net lock. Increasing the limit did not help as there was no wakeup of the waiting pools. So introduce pool_wakeup() and run through the mbuf pool request list when the limit changes. OK dlg@ visa@ |

i8254_delay(): simplify tick computation Back in the mid-90s these optimizations probably made sense, but these days the compiler will produce even better code if we just explicitly use 64-bit math and do the obvious thing. [email protected] even popped in on tech@ to agree. ok guenther@ |
