Summary: SELinux is preventing /usr/bin/gcm-apply "read" access to device 003. Detailed Description: [gcm-apply has a permissive type (xdm_t). This access was not denied.] SELinux has denied gcm-apply "read" access to device 003. 003 is mislabeled, this device has the default label of the /dev directory, which should not happen. All Character and/or Block Devices should have a label. You can attempt to change the label of the file using restorecon -v '003'. If this device remains labeled device_t, then this is a bug in SELinux policy. Please file a bg report. If you look at the other similar devices labels, ls -lZ /dev/SIMILAR, and find a type that would work for 003, you can use chcon -t SIMILAR_TYPE '003', If this fixes the problem, you can make this permanent by executing semanage fcontext -a -t SIMILAR_TYPE '003' If the restorecon changes the context, this indicates that the application that created the device, created it without using SELinux APIs. If you can figure out which application created the device, please file a bug report against this application. Allowing Access: Attempt restorecon -v '003' or chcon -t SIMILAR_TYPE '003' Additional Information: Source Context system_u:system_r:xdm_t:s0-s0:c0.c1023 Target Context system_u:object_r:device_t:s0 Target Objects 003 [ chr_file ] Source gcm-apply Source Path /usr/bin/gcm-apply Port <Unknown> Host (removed) Source RPM Packages gnome-color-manager-2.30.1-1.fc13 Target RPM Packages Policy RPM selinux-policy-3.7.19-21.fc13 Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Plugin Name device Host Name (removed) Platform Linux (removed) 2.6.33.5-112.fc13.x86_64 #1 SMP Thu May 27 02:28:31 UTC 2010 x86_64 x86_64 Alert Count 1 First Seen Thu 01 Jul 2010 09:37:34 AM EAT Last Seen Thu 01 Jul 2010 09:37:34 AM EAT Local ID 5d595946-682b-47f3-9e02-5cbf42b96442 Line Numbers Raw Audit Messages node=(removed) type=AVC msg=audit(1277966254.858:12): avc: denied { read } for pid=1622 comm="gcm-apply" name="003" dev=devtmpfs ino=15114 scontext=system_u:system_r:xdm_t:s0-s0:c0.c1023 tcontext=system_u:object_r:device_t:s0 tclass=chr_file node=(removed) type=SYSCALL msg=audit(1277966254.858:12): arch=c000003e syscall=2 success=yes exit=4294967424 a0=7ffff69c7ef0 a1=0 a2=d a3=fffffffd items=0 ppid=1 pid=1622 auid=4294967295 uid=42 gid=472 euid=42 suid=42 fsuid=42 egid=472 sgid=472 fsgid=472 tty=(none) ses=4294967295 comm="gcm-apply" exe="/usr/bin/gcm-apply" subj=system_u:system_r:xdm_t:s0-s0:c0.c1023 key=(null) Hash String generated from device,gcm-apply,xdm_t,device_t,chr_file,read audit2allow suggests: #============= xdm_t ============== allow xdm_t device_t:chr_file read;
Could you try to execute find /dev -type c -context "*:device_t:*" You probably will not get any outputs. This means the USB device is now labelled correctly. Also please update your selinux-policy. yum update selinux-policy-targeted
