While all ?real? ttys may support TIOCGPGRP, /dev/console doesn?t; using TCGETS here allows Linux booted with init=/bin/mksh-static to have working interactive command line (PS1, editing, etc).

I guess what I wanted to say is that it might be desirable to have the klibc shell do some dancing (perhaps controlled by some flags, but on by default?) If getpid() == 1 then fork a child, continue in the child, have the parent wait for the child to terminate, then exit child should setsid() close(2) close(1) close(0) open("/dev/ttyS0", O_RDONLY) open("/dev/ttyS0",

Does ctrl+c work? My experience with (non klibc) init=/bin/bash is that getting ctrl+c to work requires some jumping through hoops, because running as pid 1 doesn't really work. If I recall correctly you have to call setsid, and open a tty as a controlling tty, you can't call setsid as pid 1. The hack that I got to work (for reference, I'm using this for raw kernel testing

Hi! as I just noted, after scp the connection does not shut down properly. When I do a "scp file targethost:path", on targethost a "sshd" process is left running. I do use --with-default-path="/usr/local/openssh/bin:/usr/bin:/usr/local/bin" to assure, that the corrensponding openssh-scp is used. It also seems, that normal sessions are not always closed properly.

...o put it into some other file since it's probably needed for other systems, too. Does anybody know of other systems? Otherwise I'll send a patch which defines it only for Cygwin. But especially, I don't see a reason why the good old foregroundproc() function unconditionally uses ioctl(TIOCGPGRP) now instead of testing for HAVE_TCGETPGRP as before, when the function was in scp.c. Worse, the test for tcgetpgrp has been removed from configure.ac. This definitely is a showstopper for Cygwin. I reverted the patch in my local sandbox already and it builds again. I'd like to know if I sh...

...Severity: critical Priority: P2 Component: Build system AssignedTo: openssh-unix-dev at mindrot.org ReportedBy: vinschen at redhat.com Three bugs: - libgen.h doesn't exist on all platforms. - basename() doesn't exist on all platforms. - ioctl(TIOCGPGRP) doesn't exist on all platforms. This is a reintroduced problem since there was another method used on other platforms (calling tcgetpgrp()) when that code was still in scp.c The attached patch solves all three problems, the basename() problem only for Cygwin, the other problems general...
