* agetty: make --remote to forward --nohostname as -H to loginSami Kerola2017-04-032-5/+12
| | | | | | | | | | | | Without this change an attempt to remove hostname printing required following rather clumsy agetty invocation. /sbin/agetty --nohostname --login-options '/bin/login -H -- \u' After the change --nohostname behaves similar way with --host option, that is when combined with --remote the effect is passed to login(1).

* agetty: fix characters reorder in login promptKarel Zak2017-03-271-12/+34
| | | | | | | | | | | | | | The current agetty uses TIOCSTI ioctl to return already read chars from login name back to the terminal (without read() before tcsetattr() we will lost data already written by user). The ioctl based solution is fragile due to race -- we can return chars when terminal already contains another new chars. The result is reordered chars in login name. The solution is to use extra buffer for already read data. Reported-by: Michael Tretter <m.tretter@pengutronix.de> Signed-off-by: Karel Zak <kzak@redhat.com>

* write: stop removing and adding /dev/ in front of tty stringSami Kerola2016-07-042-43/+39Star
| | | | | | | | | | | Add both path and tty name representations of tty's to control structure, that point to same string beginning from different depths. This way there is no need to removing and adding /dev/ in front of tty string all the time. Secondly this change makes it possible to use of get_terminal_name() from ttyutils.c.

* write: tell when effective gid and tty path group mismatchSami Kerola2016-07-041-2/+7
| | | | | | | | | | | | | | | | | | Most commonly this error happens when write(1) executable does not have correct group ownership and setgid bit. The earlier message was unclear what exactly was wrong. $ mesg is y $ write testuser write: you have write permission turned off Alternatively the 'getegid() == s.st_gid' could be considered unnecessary. Afterall if to write to destination tty is denied that does not go unnoticed at thet time when tty is opened.

| | | | | | | | | | By looking the code one will had hard time knowing that a slice of ctime() from characters 11 to 16 is HH:MM time format. Use of strftime("%H:%M") makes this a lot less mysterious. In same go make \007 hex printouts to be \a that is the same thing: alarm. Signed-off-by: Sami Kerola <kerolasa@iki.fi>
