IP Tables network magic SysRq

IP Tables network magic SysRq is a Linux iptables target that allows to do the same as the magic SysRq key on a keyboard does, but over the network. It includes syncing disks, remounting them read-only, rebooting the machine, etc.

            ipt_sysrq is nice but it lacks some functionality that can make it even more useful. On clustered environments one node may "Shoot The Other Node In The Head" using methods such as IPMI, or using the SysRq-b feature from ipt_sysrq. Before you do that you may want the stack traces on the machine you want to shoot, however the way ipt_sysrq is implemented you always get the interrupt context in the stack trace and it will not be very useful. A nice patch I implemented creates a rsysrq kernel thread and saves the request on a list. Items on the list are then sysrq-ed one by one out side of the interrupt context and you actually get a meanningfull stack trace. I can send this if any one is interested.
