Bug 11083

It appears as if running the piranha components with an lvs.cf file that
has more than one virtual server, with the persistent parameter set for any
virtual server OTHER than the first one results in a SegFault when running
the lvs component with the --nofork option.  According to my debugging it
appears as if the Segfault occurs when the doSyslog function (in util.c)
calls the syslog function.

For example, this lvs.cf will work:

primary = 172.26.219.3
nat_router = 172.26.132.1 eth0:1
network = nat
service = lvs

virtual test1 {
  address = 172.26.219.96 eth1:1
  active = 1
  scheduler = rr
  port = 443

  server real1-1 {
    address = 172.26.132.33
    active = 1
    weight = 1
  }

  server real1-2 {
    address = 172.26.132.34
    active = 1
    weight = 1
  }
}

virtual test2 {
  address = 172.26.219.97 eth1:1
  active = 1
  scheduler = rr
  port = 443

  server real2-1 {
    address = 172.26.132.35
    active = 1
    weight = 1
  }

  server real2-2 {
    address = 172.26.132.36
    active = 1
    weight = 1
  }
}

So will this one:

primary = 172.26.219.3
nat_router = 172.26.132.1 eth0:1
network = nat
service = lvs

virtual test1 {
  address = 172.26.219.96 eth1:1
  active = 1
  scheduler = rr
  port = 443
  persistent = 60

  server real1-1 {
    address = 172.26.132.33
    active = 1
    weight = 1
  }

  server real1-2 {
    address = 172.26.132.34
    active = 1
    weight = 1
  }
}

virtual test2 {
  address = 172.26.219.97 eth1:1
  active = 1
  scheduler = rr
  port = 443

  server real2-1 {
    address = 172.26.132.35
    active = 1
    weight = 1
  }

  server real2-2 {
    address = 172.26.132.36
    active = 1
    weight = 1
  }
}

But this one will not:

primary = 172.26.219.3
nat_router = 172.26.132.1 eth0:1
network = nat
service = lvs

virtual test1 {
  address = 172.26.219.96 eth1:1
  active = 1
  scheduler = rr
  port = 443
  persistent = 60

  server real1-1 {
    address = 172.26.132.33
    active = 1
    weight = 1
  }

  server real1-2 {
    address = 172.26.132.34
    active = 1
    weight = 1
  }
}

virtual test2 {
  address = 172.26.219.97 eth1:1
  active = 1
  scheduler = rr
  port = 443
  persistent = 60

  server real2-1 {
    address = 172.26.132.35
    active = 1
    weight = 1
  }

  server real2-2 {
    address = 172.26.132.36
    active = 1
    weight = 1
  }
}
