    rxrpc: Fix missing security check on incoming calls · 063c60d3
    David Howells authored
    Fix rxrpc_new_incoming_call() to check that we have a suitable service key
    available for the combination of service ID and security class of a new
    incoming call - and to reject calls for which we don't.
    
    This causes an assertion like the following to appear:
    
    	rxrpc: Assertion failed - 6(0x6) == 12(0xc) is false
    	kernel BUG at net/rxrpc/call_object.c:456!
    
    Where call->state is RXRPC_CALL_SERVER_SECURING (6) rather than
    RXRPC_CALL_COMPLETE (12).
    
    Fixes: 248f219c ("rxrpc: Rewrite the data and ack handling code")
