Udev AVC spawning a script

[Aurelien Bompard]

Hi,

I comaintain synce (a framework to connect to PocketPC devices) in Fedora,
and since Fedora 7 it does not autoconnect the device when plugged in.

Autoconnection is done by an Udev rule :
# cat /etc/udev/rules.d/60-synce.rules
ACTION=="add", SUBSYSTEM=="usb_device", SYSFS{idVendor}=="0bb4",
SYSFS{idProduct}=="0a06", SYMLINK+="ipaq",
RUN+="/usr/bin/synce-serial-start"

synce-serial-start is a shell script that sources a
file: /usr/share/synce/synce-serial-common

On F7, I get AVC messages for getattr and read permissions from
synce-serial-start to this file:

type=AVC msg=audit(1180872169.345:3815): avc:  denied  { getattr } for 
pid=31270 comm="synce-serial-st" name="synce-serial-common" dev=sda2
ino=438256 scontext=system_u:system_r:udev_t:s0-s0:c0.c1023
tcontext=system_u:object_r:usr_t:s0 tclass=file

type=AVC_PATH msg=audit(1180872169.345:3815): 
path="/usr/share/synce/synce-serial-common"

type=AVC msg=audit(1180872169.345:3816): avc:  denied  { read } for 
pid=31270 comm="synce-serial-st" name="synce-serial-common" dev=sda2
ino=438256 scontext=system_u:system_r:udev_t:s0-s0:c0.c1023
tcontext=system_u:object_r:usr_t:s0 tclass=file

How should I label /usr/share/synce/synce-serial-common to allow access from
udev_t ?
And in general, how can I view which labels are allowed (and in which way)
for a given type ?

Thanks !

Aurélien
