* textual: add a docstring to most of the utilitiesBenno Schulenberg2015-01-061-0/+3
| | | | | | | | | This adds a concise description of a tool to its usage text. A first form of this patch was proposed by Steven Honeyman (see http://www.spinics.net/lists/util-linux-ng/msg09994.html). Signed-off-by: Benno Schulenberg <bensberg@justemail.net>
* textual: remove some inconsistent periods from error messagesBenno Schulenberg2014-08-111-2/+2
| | | | | | While doing so, also improve translatability and some wordings. Signed-off-by: Benno Schulenberg <bensberg@justemail.net>

* agetty: beside virtual consoles support xvc and hvc device lines as wellWerner Fink2014-05-131-5/+12
| | | | | | | | 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 Fink2014-05-131-1/+7
| | | | | | | | | | | | | | | | | 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 Fink2014-05-131-1/+50
| | | | | | | | 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 Zak2014-01-241-2/+2
| | | | | | | | | | | | | | 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>

* sulogin: don't run if not found passww entry [coverity scan]Karel Zak2013-03-271-0/+1
| | | | | | | | sulogin(8) should not run if there is no /etc/{passwd,shadow} entry and --force command line option is no specified otherwise NULL pointer dereference is possible. Signed-off-by: Karel Zak <kzak@redhat.com>

* include/ttyutils: add default chardataWerner Fink2013-01-081-4/+0Star
| | | | | | | | | | | | this one moves the init_chardata to include/ttyutils.h as well as to lib/include/ttyutils.c. Also the macros CTL/CTRL are fixed in agetty.c and sulogin.c to use the XOR variant CTL. [kzak@redhat.com: use macro rather than global variable for default chardata] Signed-off-by: Werner Fink <werner@suse.de> Signed-off-by: Karel Zak <kzak@redhat.com>
* sulogin: don't use {de,con}structor attributesKarel Zak2012-12-231-0/+4

* sulogin: remove consoles.c from libcommonKarel Zak2012-12-231-1/+1
| | | | | | | | - move struct chardata to include/ttyutils.h - move console.{h,c} to login-utils/sulogin-* (it's sulogin specific) - fix sulogin and agetty includes Signed-off-by: Karel Zak <kzak@redhat.com>

* sulogin: add multi console feature from SysVinit suloginWerner Fink2012-12-181-149/+516
| | | | | | | | | | | | | Now after adding Conflicts=rescue.service to getty@.service and serial-getty@.service and Conflicts=getty.target to rescue.target all works with `systemctl rescue'. Even adding init=/sbin/sulogin to the kernels command line by using the `e' key in grub2 boot menu works flawless. This version is without the emergency code as I've this moved to lib/console.c where it belongs to. Signed-off-by: Werner Fink <werner@suse.de>
* sulogin: use alarm function to indicate if a timeout occursWerner Fink2012-12-181-3/+17

| | | | | | | | | | The virtual console initialization has been removed by Dave's commit 5ec4a799c2a8d25c4c8260772363392f805b0a54. We already use this tty initialization for agetty, so reuse the same code. Signed-off-by: Karel Zak <kzak@redhat.com>

* sulogin: use pathnames.h for file locationsDave Reisner2012-03-121-14/+12Star

* sulogin: get rid of calls to /bin/sashDave Reisner2012-03-121-7/+0Star

* sulogin: replace older signal() with sigaction()Dave Reisner2012-03-121-20/+35
| | | | | | | | | This provides a more reliable means of saving and restoring signal handlers and avoids ugly (invalid) function pointer assignments.
