Description Bastien Nocera 2007-02-22 17:59:16 EST

Trying to change the brightness on the desktop, using gnome-power-manager, I get
avc errors with selinux in enforcing mode.

Feb 22 22:55:30 randel kernel: audit(1172184930.763:333): avc:  denied  { write
} for  pid=2053 comm="hal-system-lcd-" name="sonypi" dev=proc ino=-268434518
scontext=user_u:system_r:hald_t:s0 tcontext=system_u:object_r:sysctl_irq_t:s0

$ ls -lZ /dev/sonypi 
crw-------  root root system_u:object_r:device_t       /dev/sonypi
$ ls -lZ /usr/lib/hal/scripts/linux/hal-system-lcd-*

-rwxr-xr-x  root root system_u:object_r:lib_t         

$ cat /etc/sysconfig/selinux 
# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
#       enforcing - SELinux security policy is enforced.
#       permissive - SELinux prints warnings instead of enforcing.
#       disabled - SELinux is fully disabled.
# SELINUXTYPE= type of policy in use. Possible values are:
#       targeted - Only targeted network daemons are protected.
#       strict - Full SELinux protection.

# SETLOCALDEFS= Check local definition changes
