Description Jan "Yenya" Kasprzak 2010-03-16 07:47:00 UTC 
Description of problem:

"ipvsadm -L" reports always zeros in the "ActiveConn" column.

Version-Release number of selected component (if applicable):
ipvsadm-1.25-4.x86_64

How reproducible:
100%

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.


Additional info:
The ipvsadm binary from the ipvsadm-1.24-8.1.x86_64 Fedora 7 package reports the correct number of active connections on the same system (I have just replaced the /sbin/ipvsadm binary with the older one). So the problem is in the ipvsadm binary, not in the kernel.

Patch for this bug

There is a patch in the ipvsadm-devel list:

http://archive.linuxvirtualserver.org/html/lvs-devel/2010-02/msg00006.html

(the web archive mangles whitespace, so I am attaching the clean patch here as well). I have rebuilt the ipvsadm package from src.rpm + this patch, and verified that it fixes the problem. Please include the patch in the official distribution.
