Hi, tinc has a fixed timeout of 1 second for select() in the main loop. I think this could be improved. Do you think the following patch goes into the right direction ? I don't know whether pselect() is standard enough (works under "current" linux, however I don't know about the other arches). Maybe a config option is necessary. It's probably possible

I have an initial port of the SSH client. Only one known issue with it. sigaddset(), sigempty(), and sigprocmask() don't exist on NeXT without using libposix which I'm now avoiding (thanks, Garance A Drosehn) like the plague because it conflicts too much. Only thing this affects is the readpass.c file at this point. Which means if you ctrl-C out of the password prompt...

Patch registers SIGTSTP hook where it sends reset terminal color control sequence using write and fsync. Handler is installed only if signal is not being ignored. Patch uses rl_free_line_state and rl_cleanup_after_signal to unhook readline from terminal, then it calls original TSTP handler using approach in URL below and again hooks readline using rl_reset_after_signal. Handling is based on code

...). BTW, this patch is against 1.2.2 (since it was released before I was able to relase my patch. =) Known issues with my port (and my internal tree): 1) lack of utmp entries. I think I know what is wrong. 2) lack of signal capturing in readpass.c (I omited this from the patch) due to lack of sigaddset, sigemtyset, and sigprocmask functions outside of using libposix. 3) lost of warning. Most are ignorable. 4) Current patch *IS NOT* complete enough to support out of box next compiling. But it works against 1.2.2x ssh both client/server and works with itself. So it's progress. ------------...
