(Second try to send this. I wonder if the first one gotten eaten by a spam filter; I'll link to patches instead of attaching them.) Here are the tincctl patches I've been working on. They apply to http://www.tinc-vpn.org/svn/tinc/branches/1.1@1545. I intend to commit them once the crypto stuff's fixed. Since they're basically done, I'm emailing them now for review and in case

...he relay path has a smaller PMTU than the first edge. Therefore it appears we need a way to figure out, for a specific node, what the "indirect PMTU" (i.e. PMTU when relaying) is. This information would presumably be stored in an "indirect_mtu" field (or something like that) in node_t, and maintained separately from the "mtu" field which is set by the normal discovery process. Interestingly, this piece of information could perhaps also be used to kickstart PMTU discovery, using the indirect PMTU as a "hint" to constrain the initial range and thereby making i...

Hello Mentors, I am currently finding bug in Local Function related optimization due to which runtime failures are observed in some test cases, as those test cases are containing very large function with recursion and object oriented code so I am not able to find a pattern which is causing failure. So I tried following simple case to understand expected behavior from this optimization. Consider

...in each node. This would solve the first two issues by switching from a "pull" model to a "push" model for propagating a node's real UDP address. It would also solve the fourth issue by storing received UDP address information in two separate places (edge_t::address and node_t::address, respectively). In addition, this mechanism makes more sense (well, in my mind at least) because edge_t::address is already used to determine UDP addresses anyway. Furthermore, it would probably work even with old clients because if my understanding of the code is correct, they already...
