Description Jan Stodola 2011-05-12 12:16:50 UTC

Description of problem:
After installation of Fedora 15 for s390x and rebooting into installed system, root is not able to login via x3270 terminal emulator:

...
Fedora release 15 (Lovelock)  
Kernel 2.6.38.3-18.fc15.s390x on an s390x (ttyS0)
  
rtt7.xxx login: root
root 
Password: xxx
 
Login incorrect 


This is caused by starting "ttyS0" on terminal instead of "console". With RHEL6 or Fedora 14, "console" is opened on terminal:


Fedora release 14 (Laughlin)  
Kernel 2.6.35.6-45.fc14.s390x on an s390x (console)  
  
rtt6 login: root
root  
Password: xxx
  
Last login: Thu May 12 07:37:29 from vpn1-xxx
Ýroot@rtt6 ~¨# tty
tty  
/dev/console  


To be consistent with previous releases, systemd should open /dev/console on terminal, since "console" is allowed in /etc/securetty, "ttyS0" is not allowed:

[root@rtt7 ~]# grep ttyS0 /etc/securetty 
[root@rtt7 ~]# grep console /etc/securetty 
console


Version-Release number of selected component (if applicable):
systemd-24-1.fc15.s390x

How reproducible:
always

Steps to Reproduce:
1. install F15 for s390x
2. reboot
3. try to login as root via terminal
  
Actual results:
Login fails

Expected results:
root can login via terminal

Comment 2 Dan Horák 2011-05-12 14:02:56 UTC

After a discussion with Lennart it is an issue in pam_securetty where it must check also for devices from /sys/class/tty/console/active in addition to the console= kernel parameter. New bug will be filed.
