IPsec NAT in linux 2.6

Incomplete HowTo

Resource temporarily unavailable - solution

Linux kernel 2.6.x returns error EAGAIN when a SPD rule requires IPsec connection, but no SA is in place. In such a case racoon is woken up to negotiate the SA with the peer, but the connect(2), sendto(2), ... syscalls return with EAGAIN immediately. This patch inverts the default behaviour of the kernel to block the syscall until an appropriate SA is in place. In most setups this is wanted. In fact I suspect the current kernel code was ment to do this, but it contains a simple typo that lets it do the opposite ;-)
