Re: [panic] Kernel corruption of pppoe lists
I have same problem, and we are not alone. See http://www.freebsd.org/cgi/query-pr.cgi?pr=137881 (PR: kern/137881) You may append to this PR. - Original Message - From: "Mel Flynn" To: Cc: Sent: Friday, September 04, 2009 3:39 PM Subject: [panic] Kernel corruption of pppoe lists Description: I realize the kernel is a bit old, but it also very hard to reproduce. Kernel was up 56 days and this crash happened shortly after a very long connect time, hangup by ISP and some renegotiation issues. I can provide the ppp.log of the incident if needed. What bothers me is the contents of the session list element, preceding the element cannot be accessed. Clearly, there is random kernel memory present there, judging from ether_dhost and ether_shost. #7 0xc06cd0a0 in pppoe_findsession (privp=0xc4258000, wh=Variable "wh" is not available. ) at /data/RELENG_7/src/sys/netgraph/ng_pppoe.c:567 #8 0xc06ce1a0 in ng_pppoe_rcvdata_ether (hook=0xc41b6380, item=0xc4256120) at /data/RELENG_7/src/sys/netgraph/ng_pppoe.c:1612 ___ freebsd-net@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to "freebsd-net-unsubscr...@freebsd.org"

bsnmpd HighCounters on if_lagg
I have BRAS based on FreeBSD 7.2 and mpd 5.3 and three NIC's grouped into if_lagg with LACP, I need to monitor bandwidth with bsnmpd and cacti, by default lagg interface baud rate is 10Mbitps, so bsnmpd can't collect Counter64 on this interface. I'm modify if_lagg.c file: function lagg_link_state(): u_long new_baudrate; SLIST_FORAECH(lp, &sc_ports, lp_entries) if (lp->lp_link_state == LINK_STATE_UP) new_baudrate += lp->lp_ifp->if_baudrate; sc->sc_ifp->if_baudrate = new_baudrate; So, bsnmpd shows ifHighSpeed and ifHC(In|Out)Octets. I'm happy. Also i have if_vlan interfaces over the if_lagg, and vlan interfaces have baud rate 10Mbitps too. I don't need Counter64 functionality on vlan interfaces, but i think develop this functionality is difficult. Please, tell me who needs this functionality. ___ freebsd-net@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to "freebsd-net-unsubscr...@freebsd.org"

Re: em driver input errors
Hello Alex, SCHED_ULE, HZ=1000: I use this too > From the output of "netstat -nI em0 -w 5": maybe mistake, did you meen "netstat -w5 em0" ? Nope, exactly as in my mail, "netstat -nI em0 -w 5". It does take 5 seconds to produce meaningful output. hmm, just comments: -nShow network addresses and ports as numbers. -lShows listen sockets -nl with -w is wrong parameters. I have PPPoE concenrator based on S3000AHV motherboard with Core2Quad 6600 and four (to load all cores in CPU) Intel PCI-E x1 and PCI-E x4 NIC's My load: ... Pretty impressive figures. And "netstat -ni" shows 0 errors on all cards? Not exactly zero, but for uptime 155 days it seems to be ok. bras1 [/usr/home/dm]# netstat -i|grep em em01500 00:15:17:71:f8:52 2457503820 20175 2096211799 0 0 em11500 00:15:17:71:f8:52 1084492221 11188 909418060 0 0 em21500 00:15:17:71:f8:52 4212941427 29566 3500442287 0 0 em31500 00:15:17:71:f8:52 2143321197 0 1878792786 0 0 This counters was made by UDP flood, when dummynet can't process all packets and swi:net loads one core up to 100%. Yes, the dummynet on this machine, its bad idea but it's working stable. (After this incident the switches now control the flood attack) NOTE: the MAC is equal because i use if_lagg(4) for this interfaces for load all cores in CPU I think it depends by motherbord, what full hardware specification are you using? with chips names The machine is a Dell PowerEdge 2850. According to its specs, the chipset is Intel E7520. Two 64-bit Xeon processors at 3.20GHz, 4 GB RAM. For you bandwidth this server must work fine. Check the UDP/ICMP or other flood on em0 when errors appear. What kind of device at the end of em0 copper cable? If this a manageable switch, and supports tools - try to investigate what happens when errors appear. ___ freebsd-net@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to "freebsd-net-unsubscr...@freebsd.org"
