Question(s) kernel

Hi

I have been browsing the Dragonfly kernel code and two questions came up:

(1) if a user process causes many "lwkt_sendmsg", either by directly invoking it or through
some table based system call. Could this lead to memory exhaustion in the kernel by flooding
the target port and eventually crash the system?


(2) http://fxr.watson.org/fxr/source/netinet/if_ether.c?v=DFBSD#L832
  "lwkt_domsg(rtable_portfn(0), &msg.netmsg.nm_lmsg, 0);"
  Is this always using cpu 0 ? And if, why?

Thank you for your answers or pointers to previous posts I missed :-)

Dominic
