   Dear IPVS Friends ,

   A - BUG report for ipvsadm 1.21/1.26 & Production release ipvsadm Patch
   request
   B- New PRODUCTION release publishing an tar tarball request
   C- Setup and publish an Offical Prod code ipvs(adm) released GIThub request

   Since the ipvs betas arround 0.2.x ipvsadm  , myself setup dozens of IPVS
   Clusters.
   I am an Linux Admin since kernel 0.4.2 , work arround as IT Freelancer .
   Linux Clusters / HA are my most avantage scope...

   Forgive me please for any language spelling typos .
   Maybe some one call this LONG  report s-p-a-m-m ..
   Myself digged into IPVS debugging past since past 5 month
   debug  ldirectord´s behavior &  keepalive that use the "stable" ipvsadm
   witch been not work properly.

   With tests path 5 month where done at OpenSuSe intel 11.4 ,
     Opensuse 12.3 arm RPI , FC remix 18 RPI , and Debian 6.0 & 7.0 RPI ,
   debian Tntel 6.0 & 7.0 , FC Tntel 16-18

   Maybe more Distributions have this issue(s) as they allmost use the OFFICAL
   STABLE ipvsadm ( v 1.21-0 ) release.
   I searched with Google for patches arround IPVS / ipvsadm.
   Found serval from  patches are from SuSe , Debian , Ubunto and Gentoo, FC ,
   Centos and others.

   08-ipvsadm-libnl-3--linking-2__debian7.patch  witch is from me for the
   libnl-3 issue gotten on debian7
   with any 1.21/ 1.26  release.

   Mysrelf droped the found used patches  to
   https://www.dropbox.com/sh/2pkbntk4enwtmd4/ZZxGm5dO1N
   I don´t  fixed gotten ipvsadm 1.26 RPM  build and debian PKG Build .
   I suggest  that  someone of the distro Maintainers may do that on theire own
   please ,  and revert back pkg BUILD patches to this mailing LIST.

   As stated by some of the ipvs-users list arround Sepbember 2012:
    !!-->>  It´s TIME for an FRESH Official Public STABLE release <<--!!
    i.e Wesong : DO it please !

   An central & Offial IPVS(adm)  GIT repro that contains all the distro made
   fixes wuold helpfully somehow i.e ....
    ( not linked somewhere yet today at i.e
   http://www.linuxvirtualserver.org/software/index.html )
   with i.e main(stable ) , dev(unstable ) and next(testing ) branches same way
   as Linux Kernel.

   Distributions  seems use allmost use ONLY  publish the "stable" stated
   release - but the last ipvsadm 1.2.1 offical was made 24-Dec-2004 - more
   then +9 years ago.

   What seems to happen :
   i.e Kernel 3.x  interfaces arround IPVS(adm) changed past 9 years with smal
   bits and typos.   i.e the stack_smashing.patch , popt and more.

   The IPVS Production release used  kernel commands  requre MUST Correct -
   allways - witch the current offial stable DOES NOT  for i.e 3.x kernels
   -

   ------------------------------------------------- My BUG Hunting agains
   offial ipvsadm 1.21 and 1.26 .
   HOW to Reproduce , see bellow email chain bug report
   - get latest  tarballs from
   http://www.linuxvirtualserver.org/software/index.html
   - build unchanged / unpatched  it on an actual Linux  OS  - distribution
   don´t matter .
   - use the build ipvsadm agains an 3.2.x till 3.9.x kernel i.e with LVS-DR

   - most BUgs are known and reported somewhere  , but seems not included at
   offial stable / tarballs ,
     Either not included at the offical unstable ipvsadm 1.26 tarball.
    As said .. Offial GIT repro  with i.e main(stable ) , dev(unstable ) and
   next(testing ) branches may help  here...

    As this reason not Included as most Distributions ( i may say thanks to
   gentoo maintainers -  they did  most of them )
   - The Debian ipvsadm maintained  GIT Repro (
   https://github.com/formorer/pkg-ipvsadm )
      seems as well incomplete  with current "1.26-2".
   -  IT seems the reason for my Bug report may the  release delivered "stable"
   v 121 with debian 7 with libnl-2 usage.
   I did the search for some patches against the  ipvs 1.26 tarball  and tried
   build it .
     @debian Ipvsadm maintainer
   The  libnl-3  on  debian7  uninstalls  the  libnl2-dev  thus also  the
   /usr/lib/netlink dir ( OOPPS )
   This cause  gone after uninstall libnl2-dev by i.e apt-get
   libnl-3     path     seems     moded    from    /usr/lib/netlink    to
   /usr/include/libln3/netlink witch BREAK most netlink, iptables  and IPVS
   code.

   Thus this require at current an symlink from /usr/include/libln3/netlink to
   /usr/include/netlinkas
   as temp build fix for IPVS 1.2x

   Ipvsadm display  result from patched 1.26  with libnl-3, popt , smasch
   stacking ... :

   $  ipvsadm -Ln
   IP Virtual Server version 1.2.1 (size=4096)
   Prot LocalAddress:Port Scheduler Flags

     -> 192.168.11.155:80            Route   100    0          0


   ->>my Patch results all over :<<--
   1 -  For Kernels after 3.1.x
      i.e 3.8.7/3.8.8 as used here
     seems not longer work correctly with libln2
   2 - popt are not longer for kernel 3.2x and above , its required  for get
   ldirectord / keepalive to work.
   3 - aquedat ipvsadm kernel must be used
   Results of testings :
   - KERNEL does its LB job
   - ipvsadm does work not without patches
   - ldirectord failed due ipvsadm failed to manage the IPVS table(s).

   -----My - testbed --IPVS Setup---
   The Setup used here  been  equal to the LVS DR standard as descibed at
   Howtos .

   The issue  and BUG  here seems that the IPVSadm  update Commands Wrongly
   used.
   Thus any  failover featger faild .
   Thus


   lb2 # ifconfig eth0:0 192.168.17.240 netmask 255.255.255.255 broadcast
   192.168.11.140 arp up
   lb2 # /sbin/ipvsadm -A -t 192.168.11.140:80 -s wrr
   lb2 # /sbin/ipvsadm -a -t 192.168.11.140:80 -r 192.168.11.154:80 -g -w 100
   lb2 # /sbin/ipvsadm -a -t 192.168.11.140:80 -r 192.168.11.155:80 -g -w 100


   - all systems are at the same network switch
   - Eth1 only used by corosync and heartbeat _not_  as or by LVS.
   - i am not use the ipvsadm syncd due the usage if corosync & pachemaker
   manage the  ldirectord and not heartbeat-v3
     This allows me to run LIVE LIVE with  serval nodes running an ldirectord
   with grouped & partioned cluster nodes.
   - use lo:0 on realservers with noarp.

   kernel.sem = 250 256000 32 1024
   net.ipv4.vs.debug_level = 2

   LVS-DR test settings results :

   - when i set net.ipv4.ip_forward
     results in NO answers by realservers.

   -     usage     of      net.ipv4.conf.all.arp_ignore     =     1     ,
   net.ipv4.conf.all.arp_announce = 2
    results in NO answers by realservers.
     Thus the IPVS-DR / IPVS-TUN  HOWTO that descrice to set thus shuold be
   adement  for kernel 3.x ,
     3.x kernels may require extra iptables entrys.
     Not to happen on 2.6.x kernels - tested

   Important Fault here :
   - ipvsadm use due no smash stacking patch & popt the wrong CMD to kernel ,
     thus the weight set to ZERO ,

    -  seems goten  answer of BOTH real servers via IPVS ...

   -  ipvs(adm)  faild to show the second host
    -  If i stop shown realserver , the failover & fallback not works due the
   ipvsadm commands issue.

    -  IPVS table not updated  when shutdown  one of the real servers
    -> ipvsadm faild to show the second host, thus ldirectord / keepalived
   faulted to IPVS updates..

    ->  ldirectord or keepalived failed due kernel IPVS table failed updated.
