https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=244584 Bug ID: 244584 Summary: netstat -sz clears igmp version in kernel memory. Subsequent netstat -s reports igmp version error Product: Base System Version: CURRENT Hardware: Any OS: Any Status: New Severity: Affects Some People Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: ghuckriede@blackberry.com Overview: When netstat clears the socket stats it causes the igmp version to be cleared also. This causes the display of the igmp stats to display an error. Steps to Reproduce: # netstat -sz # netstat -sp igmp Actual Results: After running netstat with "-sz" any subsequent display of the igmp protocol will result in the following error messages being displayed netstat: igmp_stats: version mismatch (0 != 3) Expected Results: No error message after clearing stats Build Date & Hardware: 12.0 FreeBSD FreeBSD_12.0_ghuckriede 12.0-RELEASE-p3 FreeBSD 12.0-RELEASE-p3 GENERIC amd64 HEAD uname -a FreeBSD FreeBSD_head_ghuckriede 13.0-CURRENT FreeBSD 13.0-CURRENT #2 r358592: Tue Mar 3 15:38:05 EST 2020 ghuckriede@FreeBSD_head_ghuckriede:/usr/obj/usr/src/amd64.amd64/sys/GENERIC amd64 Additional Information: Using a debugger shows that the entire igmpstat structure is getting cleared after the netstat -sz command.
