[Libdlo] Multiseat config problem...

[Jonathan D. Proulx]

Hi Bernie,

Thanks for writing up the multiseat stuff!

After a couple of issue with finding missing execute bits and a script
I forgot to copy into play I think I've narrowed the actual problem
to:

run_program: '/bin/cat /sys//class/input/input12/mouse2/../../../../../devnum'
run_program: '/bin/cat' (stderr) '/bin/cat: /sys//class/input/input12/mouse2/../../../../../devnum: No such file or directory'

presumably it wants to get to one of these:

[jon at kvas multiseat-bits]$ find /sys/ -name devnum
/sys/devices/pci0000:00/0000:00:1a.0/usb1/devnum
/sys/devices/pci0000:00/0000:00:1a.0/usb1/1-1/devnum
/sys/devices/pci0000:00/0000:00:1a.1/usb2/devnum
/sys/devices/pci0000:00/0000:00:1a.2/usb3/devnum
/sys/devices/pci0000:00/0000:00:1a.7/usb4/devnum
/sys/devices/pci0000:00/0000:00:1a.7/usb4/4-2/devnum
/sys/devices/pci0000:00/0000:00:1a.7/usb4/4-2/4-2.2/devnum
/sys/devices/pci0000:00/0000:00:1a.7/usb4/4-2/4-2.4/devnum
/sys/devices/pci0000:00/0000:00:1d.0/usb5/devnum
/sys/devices/pci0000:00/0000:00:1d.1/usb6/devnum
/sys/devices/pci0000:00/0000:00:1d.2/usb7/devnum
/sys/devices/pci0000:00/0000:00:1d.7/usb8/devnum
/sys/devices/pci0000:00/0000:00:1d.7/usb8/8-3/devnum
/sys/devices/pci0000:00/0000:00:1d.7/usb8/8-4/devnum
/sys/devices/pci0000:00/0000:00:1d.7/usb8/8-4/8-4.3/devnum
/sys/devices/pci0000:00/0000:00:1d.7/usb8/8-4/8-4.3/8-4.3.1/devnum
/sys/devices/pci0000:00/0000:00:1d.7/usb8/8-4/8-4.3/8-4.3.3/devnum
/sys/devices/pci0000:00/0000:00:1d.7/usb8/8-4/8-4.4/devnum
/sys/devices/pci0000:00/0000:00:1d.7/usb8/8-5/devnum
/sys/devices/pci0000:00/0000:00:1d.7/usb8/8-5/8-5.2/devnum

But can't figure any number of ../ paths that will get there
/sys//class/input/input12/mouse2/device/../devnum
does exist

but is apparently the wrong thing, switching the rules to use that
gives me:

ls -R /dev/usbseat/
/dev/usbseat/:
17  18  3

/dev/usbseat/17:
mouse

/dev/usbseat/18:
keyboard

/dev/usbseat/3:
display

So the rules are getting triggered, but I'm not sure what devnums we
want to pull
