* agetty: use the "best" interface for \4 and \6Karel Zak2014-05-132-42/+67
| | | | | | | | | | | | The issue file escape sequences \4 and \6 prints the host IP when no interface is specified. That's useless on some virtual machines where gethostname()+getaddrinfo() returns 127.0.0.1. The seems better to print IP of the "best" interface (UP, RUNNING, non-LOOPBACK) and use gethostname() as painful fallback only.

* agetty: beside virtual consoles support xvc and hvc device lines as wellWerner Fink2014-05-131-12/+11Star
| | | | | | | | For this approach do not use the ioctl TIOCMGET anymore as this is for real serial lines only. But switch over to use the ioctl KDGKBMODE as this is unique to the virtual console lines only. Signed-off-by: Werner Fink <werner@suse.de>
* agetty: better support of the special system consoles on S390Werner Fink2014-05-131-5/+10
| | | | | | | | | | | | | | | | | That is that there are several consoles, the /dev/ttyS0 which is type of ibm3215 and a dumb terminal, then there is the device /dev/3270/tty1 which can handle ANSI color escape sequences and is a ibm327x terminal, and the /dev/ttyS1 which is a vt220 terminal. The macro is_speed() in agetty.c allows to distinguish between the terminal line (/dev)3270/tty1 and the speed options on the command line used in /run/systemd/generator/getty.target.wants/serial-getty@3270-tty1.service which is a symbolic link to /usr/lib/systemd/system/serial-getty@.service Signed-off-by: Werner Fink <werner@suse.de>
* agetty: avoid that agetty nor sulogin are fooled by a running plymouthWerner Fink2014-05-131-7/+68
| | | | | | | | The nowadays used plymouth locks the devices used for the system console which causes that agetty as well as sulogin can not modify the termios settings of e.g. the serial devices of the systenm console. Signed-off-by: Werner Fink <werner@suse.de>

* include/c.h: prefer nanosleep() over usleep()Karel Zak2014-01-241-1/+1
| | | | | | | | | | | | | | Let's use nanosleep() although if usleep() exists. The nanosleep function does no interact with signals and other timers. The patch introduces xusleep() as replacement to libc (or our fallback) usleep(). Yes, we don't want to use struct timespec + nanosleep() everywhere in code as nano-time resolution is useless for us. The patch also enlarges delays in some busy wait loops. It seems enough to try read/write 4x per second. Signed-off-by: Karel Zak <kzak@redhat.com>

* script: script input redirection / eof handlingKarel Zak2013-12-031-19/+79
| | | | | | | | | | | | | | | | | | | | | | | echo "ps uf" | script does not work because script assume that stdin is terminal and it does not forward EOF to the pty. This patch: * make non-tty use-case more robust (don't call tty ioclts to non-tty file descriptors. * send EOF (CTL('D') control char) to the master channel when detected eof by read() on stdin * wait for empty master and slave file descriptors to be sure that we don't miss date for typescript. This is also necessary to be sure that slave channel (shell) is completely initialized otherwise EOF is ignored.

* | clean up term lib handlingMike Frysinger2013-09-301-5/+2Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The ncurses package has been providing pkg-config files for a while now. So let's start using them to get the proper linker & compiler flags. It can make a difference when ncurses is configured in a way that requires extra link time flags but util-linux doesn't provide them, or when the headers live in a weird place and util-linux can't find them. Since the NCURSES_LIBS is always defined for the Makefile, there's no need to gate on the HAVE_NCURSES conditional. When it's disabled, the var will simply be empty. With a minor tweak to how tinfo is handled, we can do the same thing -- we just always use TINFO_LIBS in the Makefile's. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* | setterm: fix term.h/ncurses.h include orderingMike Frysinger2013-09-301-2/+3
|/ | | | | | | | | | | | | | | | | | | The ncurses term.h header has logic in it to detect if nucrses.h has already been included and void defining things when it has. But since setterm includes term.h and the ncurses.h, it doesn't work and we can get fun build-time warnings like: CC term-utils/setterm-setterm.o In file included from term-utils/setterm.c:109:0: /usr/include/ncursesw/ncurses.h:827:12: warning: redundant redeclaration of 'tigetflag' [-Wredundant-decls] extern NCURSES_EXPORT(int) tigetflag (NCURSES_CONST char *); /* implemented */ ^ In file included from term-utils/setterm.c:106:0: /usr/include/ncursesw/term.h:775:12: note: previous declaration of 'tigetflag' was here extern NCURSES_EXPORT(int) tigetflag (NCURSES_CONST char *); ^ Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* agetty: add \S to output /etc/os-release dataKarel Zak2013-09-122-2/+111
| | | | | | | | | | | | | | | | | | | | | | | | | | This patch allows to use a new \S or \S{VARNAME} sequence in the /etc/issue file. The sequence prints data from /etc/os-release. The reason is to keep /etc/issue file distribution and release independent. The \S{ANSI_COLOR} is converted to the real terminal escape seq. For example: \S Kernel \r on an \m (\l) or more complex example: Welcome to \S{ANSI_COLOR}\S{NAME}0m \S{VERSION} Report bugs at \S{BUG_REPORT_URL}. See http://www.freedesktop.org/software/systemd/man/os-release.html fr more details about /etc/issue. Based on patch from Bill Nottingham <notting@redhat.com>.

| | | | | | | | | | | | | Earlier test failed when user had write permission, but was not in special group that owns terminal devices, usually tty. This made write(1) to fail for root, if the root did not happen to be in tty group. In this commit root is granted ot write to anyone, even if they have mesg(1) turned off. For an user who is trying to write to own other session the group write bit is significant only for whether mesg(1) are enabled. Signed-off-by: Sami Kerola <kerolasa@iki.fi>

| | | | | | | | | | | | Sessions that has in utmp data ut_line begining with ':' are skipped. This is done to avoid write errors to devices such as '/dev/:0'. For example wdm is reported to to generate such utmp line. Perhaps in future this code should be revalidated. If an utmp data contains broken device lines it might be best inform user with a error message, rather than skipping silently suspicious device entries. Signed-off-by: Sami Kerola <kerolasa@iki.fi>
