           Summary: ipsec causes kernel deadlock
    Kernel Version: 2.6.10-rc2
            Status: NEW
          Severity: blocking
             Owner: jgarzik@xxxxxxxxx

Distribution:slack/mfxlinux
Hardware Environment:i386
Software Environment:Openswan
Problem Description: when instantiating a gateway-network connection using
Openswan tools, the server at the 'gateway' end of the tunnel connection will
deadlock during the ISAKMP stage 1. The network-network tunnel is built
properly. Setting the boot parameter nmi_watchdog=1 does not produce any
debugging output on the console.

Steps to reproduce:
install Openswan. Build an ipsec.conf file with the 4 virtual tunnels that
comprise 1 server-server link. Set auto=add so that the connections may be
brought up manually. Instantiate ipsec. Manually ipsec auto --verbose --up
net-net, then ipsec auto --verbose --up gate-net. The machine on gate will 
deadlock.
