Hi Robert, Apologies for not getting earlier.

It is the for loop in ifindex_alloc_locked() function- for (idx = 1; idx <= V_if_index; idx++) idx is a local variable, so I figured it is V_if_index is what is causing the page fault. It does look like a NULL pointer reference - I see that V_if_index comes from that vnet instance's value and uses the macro VNET_VNET_PTR() down the chain. Since the call chain is coming from a new thread cbb_event_thread, I believe that this thread's vnet context needs to be set using CURVNET_SET(). I'll try this tomorrow, but if think I'm not on the right track or want me to try something else please let me know. Many thanks, Harsha _______________________________________________ freebsd-net@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to "freebsd-net-unsubscr...@freebsd.org"
