Description Bert Aerts 2013-05-18 22:01:41 CEST

Description of problem:

(Mageia 3 RC x86_64 plus all updates)

Plug in ACR38U USB (Belgian) identity card reader, makes pcscd service crash:

dmesg
[18041.844607] usb 1-1: new full-speed USB device number 12 using xhci_hcd
[18041.859146] usb 1-1: New USB device found, idVendor=072f, idProduct=9000

Service can not be started again, due to segmentation fault.
When device is plugged out, service pcscd can be started successfully.

Following is installed:

[bert@Dell7720Mageia3 eid-viewer-4.0.4]$ rpm -aq | grep acr38
lib64acr38u0-1.7.10-4.mga3

Same experiment in Mageia 2 x86_64 (with all updates) works perfectly well !

Comment 2 Sander Lepik 2013-05-20 15:43:06 CEST

What happens if you remove acr38 related packages? Will it crash then too or not? Just to test if the problem is in pcsc-lite or in acr38 driver..

Comment 3 Bert Aerts 2013-05-20 16:16:11 CEST

I removed acr38u packages:
lib64acr38u0-1.7.10-4.mga3
lib64acr38u-devel-1.7.10-4.mga3
acr38u-1.7.10-4.mga3

dmesg now reports
[24779.196415] usb 3-2: new full-speed USB device number 6 using xhci_hcd
[24779.210884] usb 3-2: New USB device found, idVendor=072f, idProduct=9000
[24779.210889] usb 3-2: New USB device strings: Mfr=1, Product=2, SerialNumber=0
[24779.210893] usb 3-2: Product: ACR38 USB Reader         
[24779.210895] usb 3-2: Manufacturer: ACS      

pcscd service can be stopped and started without problems.

I think that does not prove that acr38u creates the crash of pcscd service, as now nothing will happen with the device because driver is not present.

Comment 4 Sander Lepik 2013-05-20 18:11:38 CEST

I created a new package: https://www.dropbox.com/s/2zy2wrkahdx5jt9/acsccid-1.0.4-1.mga3.x86_64.rpm - If you install that one and restart pcscd would that change anything? Don't install acr38u back, just the new driver.

Comment 5 Bert Aerts 2013-05-20 20:04:15 CEST

!!! GREAT !!!

This alternative driver for ACR38U just works perfectly!

Please add this package to the Mageia 3 distribution.
And put a note in the Release Notes about it.

Comment 6 Bert Aerts 2013-05-20 20:05:03 CEST

Thank you very much, Sander !

Comment 7 Sander Lepik 2013-05-20 20:10:06 CEST

I'll submit it to Cauldron if Cauldron opens again but I'm afraid there is nothing I can do about Mageia 3 as we can't submit new packages into stable release.

Comment 8 Sander Lepik 2013-05-26 10:02:00 CEST

This is now pushed into Cauldron. I'll close this bug. If we are gonna have backports for Mageia 3 I'll backport it for Mageia 3 too. If not then we just have to deal with it.
