Hello,
It's me with yet another question about Freeswan internals. When
looking through demux.c, I see that there are a lot of comments
like
/* XXX Could send notification back */
in comm_handle and related functions. My question is basically
whether there is any plan to send these notifications back in a
future release of freeswan? I think I may have encountered a
possible issue, but perhaps I am thinking about it incorrectly.
It seems to me like you could have a situation where two
machines have built an opportunistic tunnel to each other. One
side restarts and no longer knows about the tunnel when it comes
back up. When the other side sends it a packet, the originating
side would say that it's for an unknown SA, report it to the
log, but not send a notification back. So, communication between
those machines is effectively stalled until the side that
rebooted sends a connection to the other side. Does this sound
correct?
Yours,
Jake
