[pkg-cryptsetup-devel] Bug#903574: Error 2304 in GDM login page when i use smartcard to decrypt disk and to login into Gnome Session

[Pascal Vibet - ADACIS]

Package: cryptsetup
Version: 2:2.0.2-1ubuntu1

Dear Maintainers, i propose you my fix to this problem.

I'm using smartcard to decrypt luks disk and to login into my gnome session.
At GDM3 login page, i have this error:
"Error 2304: Error Initializing the PKCS#11 module"

I unplugged my smartcard reader and i plugged it and all works fine.

I search why and i found the problem: The program PSCSD is running twice. First one is start by initramfs scripts and the second by GDM3.
I search in initramfs scripts and i found the problem:

In /usr/share/initramfs-tools/scripts/local-top/cryptopensc, PSCSD process is start and go in background. But the PID is not store, so i fix it with:
36a37
> echo $? > /var/run/pcscd.pid

In /usr/share/initramfs-tools/scripts/local-bottom/cryptopensc, there are 2 problem:
- First one: the script path is not good
23c23
< if [ ! -e /sbin/pcscd ]; then
---
> if [ ! -e /usr/sbin/pcscd ]; then

- Second one: start-stop-daemon is used but in /usr/share/initramfs-tools/scripts/local-top/cryptopensc the bloc is commented, so i do same in script and i replace it by kill command:
30c30,31
< start-stop-daemon --stop --quiet --pidfile /var/run/pcscd.pid --name pcscd
---
> #start-stop-daemon --stop --quiet --pidfile /var/run/pcscd.pid --name pcscd
> kill -15 $(cat /var/run/pcscd.pid)
  
I apply modifications:
update-initramfs -u -k all

So at boot, smartcard reader light is up when initramfs is running. After smartcard reader light is down and smartcard reader light is up when GDM3 start.
I can use my smartcard to decrypt my luks disk and to login whithout unplugged my smartcard reader.
  
Regards
