Re: dispatch tcp_close to the correct CPU to run
:In tcp_timer_2msl() we need to dispatch tcp_close() to the correct CPU
:instead of calling it directly:
It should already be on the correct cpu since the callout API is
all cpu localized. The only other entry point is via the pru_*
dispatch but I'm pretty sure that is cpu localized via
If you haven't already, I recommend we assert that it is on the
correct cpu rather then route it to the correct cpu (which it
should already be on).
However, even though it will be on the correct cpu there could be
a threading issue... it won't be in the same thread as the tcp
protocol thread. The threads are not preemptive but the could
still be a problem.
