2011-04-21no need to escape `|';Jason McIntyre
2011-04-21Add a "filter-routes" option; when set, snmpd asks the kernel not toStuart Henderson
send route updates. If you aren't interested in examining routing tables over SNMP (e.g. if you only use it for sensors or interface stats) this reduces cpu use during heavy route updates. Makes my full-table bgp routers happier when a major peer bounces. ok reyk@

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.
2010-09-20fix-up the sysORTable by using the same name (sensorsMIBObjects) as usedStuart Henderson
in the MIB, rather than a different spelling (sensorMIBObjects). ok martinh@
2010-09-20Use strvis to encode octet strings in -DDEBUG mode.Martin Hedenfal
Makes my terminal happier when debugging.
2010-09-20Return error on GET requests without an instance identifier, both forMartin Hedenfal
tables and scalar values. Fixes system/6468 by not calling table get functions with an unexpectedly short OID. Also fixes system/6071. Scalar variables without an instance specified now returns a noSuchInstance error. GetNext requests correctly returns the .0 instance. This means you can no longer rely on $ snmpget -v2c -c public localhost SNMPv2-MIB::sysDescr returning the .0 instance. You need to specify it explicitly: $ snmpget -v2c -c public localhost SNMPv2-MIB::sysDescr.0 Also return proper SNMPv2 errors per varbind instead of a noSuchName error status, unless SNMPv1 was specified in the request. An earlier version of this diff tested by Remi Laurent, thanks.

2010-08-03fix linecount bug with comments spanning multiple linesHenning Brauer
problem reported with the obvious fix for bgpd by Sebastian Benoit <benoit-lists at fb12.de>, also PR 6432 applied to all the others by yours truly. ok theo isn't it amazing how far this parser (and more) spread?
2010-07-18fix a double "is";Jason McIntyre

2010-05-26Move imsg into libutil and add a man page.Nicholas Marriott
Minor bump for libutil. Previous versions of this diff and man page looked at by various people. "you should just commit" deraadt

2010-04-27Correct sensor logic so we don't get stuck in a loop.Jonathan Gray
ok deraadt@
2010-04-27Dumb mistake done twice. First in ospfd then synced to snmpd. rtm_errnoClaudio Jeker
is only valid for messages with an rt_msghdr. So move the check back where it was before. Problem found by jsg@
2010-04-20Get rid of MAXSENSORDEVICES. Gaps in sensordev lists are now handledTheo de Raadt
by returning ENXIO instead of ENOENT, to essentially indicate hotplug sensor that has gone away. Accessing beyond the end of the sensordev list still returns ENOENT, so that you can see there are no further devices. ok kettenis oga

2010-04-07Remove XXX comment and just close received fd if calloc() fails.Nicholas Marriott
If this happens the imsg may no longer be usable as there may be queued messages, but this is a) already the case with the code now, and b) would be the case if recvmsg() fails anyway, so we can document that -1 from imsg_read() invalidates the struct imsgbuf. discussed with and ok eric
2010-04-01Track blackhole and reject flags since the MIB knows about them.Claudio Jeker
Remove an unneeded stack storage as well. OK jsg@
2010-04-01After syncing kroute with bgpd sync now against ospfd's so that this codeClaudio Jeker
uses only one rtm parser instead of three different ones. Fixes problems with priorities that were not handled everywhere correctly. Found by and OK jsg@
2010-03-31Track interface addresses in a AF independent way. This is needed to supportClaudio Jeker
the AF independent MIBs like RFC4292 in the future. Additionally count number of routes (also needed by some MIBs) and do not track the state of routes since the MIB do not require it and it is expensive. OK jsg@
2010-03-29Sync kroute.c code with bgpd so that snmpd is able to track INET6 addrs asClaudio Jeker
well. First big sync, the interface address tree still needs to be made AF independent but that will be done in a second step. OK jsg@
