Porposed patch for 8021q
Tommy Christensen get the credit for it.
reassignig to kernel Looks fine on 2.6.9-1.681_FC3 with net-snmp-5.2.3-rc3 and net-snmp-5.2.3-rc4 on my sager laptop and an Intel P3 clone. Let me know if hardware details are of any value. |
From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; rv:1.7.3) Gecko/20041003 Firefox/0.10 Description of problem: snmpd dies on machine with 802.1q interface, dmesg logs shows it may have been triggered bringing vlan interface in and out of promiscuous mode. Ooops also logged in dmesg before it died. Version-Release number of selected component (if applicable): net-snmp-5.1.1-2 kernel-2.6.8-1.521 How reproducible: Didn't try Steps to Reproduce: 1.Create eth0.3 inteface, leave eth0 as ip 0.0.0.0 2. Collect snmpod data from machine 3. Capture packets on eth0.3 Actual Results: See Oops in dmesg, then Trace from snmpd. Expected Results: snmpd does not die Additional info: Their are about 20 entries before this for promiscuous mode as well. Machine is using e100 nic card driver. 00:09.0 Ethernet controller: Intel Corp. 82541GI/PI Gigabit Ethernet Controller Subsystem: Intel Corp.

Will hit the net-snmp list with these findings as well.
