** Description changed:
Binary package hint: ipvsadm
Description: Ubuntu 10.04.1 LTS
Release: 10.04
ipvsadm:
- Installed: 1:1.25.clean-1
- Candidate: 1:1.25.clean-1
- Version table:
- *** 1:1.25.clean-1 0
- 500 http://apt-mirror1.us.archive.org/ubuntu/ lucid/main Packages
- 100 /var/lib/dpkg/status
+ Installed: 1:1.25.clean-1

there is "what appears to be a typo in the netlink client code whereby
the activeconns is read as activeconns and then overwritten by
persistentconns. The result is that the active connection count reported
by ipvsadm -L is wrong if the code is compiled to use the netlink
interface." (description taken from
http://archive.linuxvirtualserver.org/html/lvs-
devel/2010-02/msg00006.html)
the attached patch is taken from
https://bugzilla.redhat.com/show_bug.cgi?id=573921 (the same patch as
from the lvs-devel link but with unmangled whitespace)
+
+ == SRU REPORT ==
+
+ === IMPACT ===
+
+ This patch is extremely straight forward and only affects the reporting
+ code, so risk of crash/security problems are low. If somebody has built
+ a workaround for the lack of active connection reporting, or if they
+ have been assuming that the number was lower/0, the update reporting
+ accurate numbers may cause some confusion, but that should be easy to
+ correlate with the system updates.
+
+ === DEV FIX ===
+
+ The code was patched and uploaded to natty in version 1:1.25.clean-
+ 1ubuntu1
+
+ === PATCH ===
+
+ See merge proposal.
+
+ === TEST CASE: ===
+
+ From redhat bug report:
+
+ Steps to Reproduce:
+ 1. Create an IPVS virtual service, something along these lines:
+ ipvsadm -A -t this.host.ip:80
+ ipvsadm -a -t this.host.ip:80 -r other.host.ip:80 -m
+ (and set up the HTTP server on other.host.ip).
+ 2. from different host run "telnet this.host.ip 80"
+ 3. run /sbin/ipvsadm -L
+
+ Actual results:
+ The "ActiveConn" column is zero even though there is an open connection.
+
+ Expected results:
+ The "ActiveConn" column should be greater than zero.
+
+ === REGRESSION POTENTIAL ===
+
+ Very low. See IMPACT.
