Sure way to crash router with a simpl script that contain a bug, with any IOS version. Maybe someone at Cisco wants to give it a look.
Code below. Example application can be started with "call application session start <anything> <service> name.
When callTimer is reached (because the application fails to stop timer), HTTP token Gtok has been cleaned up already and router crashes.
A variant is not to use a timer and do reset after cleanup. That produces only a "Potential memory corruption" print on termina monitor.
package require httpios 1.0
proc sessInd {} {
global Gtok
set Gtok [::httpios::geturl http://54.175.219.8/ip -command callBack]
timer start call_timer0 4
}
proc callBack {token} {
puts -nonewline callBack
::httpios::cleanup $token
}
proc callTimer {} {
global Gtok
::httpios::reset $Gtok
}
set fsm(INIT,ev_session_indication) "sessInd same_state"
set fsm(INIT,ev_call_timer0) "callTimer same_state"
fsm define fsm INIT
