(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

Dit werkt wat beter, omdat de

...Hardware: All OS: Linux Status: NEW Severity: minor Priority: P5 Component: sshd Assignee: unassigned-bugs at mindrot.org Reporter: ben.maurer at gmail.com To handle sigterm, openssh uses this handler: static void sigterm_handler(int sig) { received_sigterm = sig; } in the select loop, it checks this flag ret = select(maxfd+1, fdset, NULL, NULL, NULL); ... if (received_sigterm) { select() will return -1 with an EINTR when it gets a signal. Therefore, in most cases this successfully shuts down the process. However,...
