What tool were you using that created /dev/dm-15? It is labeled incorrectly. What tools do you have in mind? I haven't created explicitly any device nor changed its SELinux attributes. Also, when my computer booted an autorelabel was done. I guess you were using nautilus.
> I was mounting an encrypted LUKS partition from an external disk
using GNOME (nautilus).
What context does
ls -lZ /dev/dm-15
show now.
brw-rw----. root disk system_u:object_r:fixed_disk_device_t:s0 /dev/dm-15 Btw, I've run restorecon -v on the file and it hasn't displayed anything. Yes it has the correct context on it now.

Summary: SELinux is preventing /usr/libexec/hald-probe-volume "ioctl" access to device /dev/dm-15. I was mounting an encrypted LUKS partition from an external disk using GNOME (nautilus). Detailed Description: [SELinux is in permissive mode. This access was not denied.] SELinux has denied hald-probe-volu "ioctl" access to device /dev/dm-15. /dev/dm-15 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 '/dev/dm-15'. 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 /dev/dm-15, you can use chcon -t SIMILAR_TYPE '/dev/dm-15', If this fixes the problem, you can make this permanent by executing semanage fcontext -a -t SIMILAR_TYPE '/dev/dm-15' 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 '/dev/dm-15' or chcon -t SIMILAR_TYPE '/dev/dm-15' Additional Information: Source Context system_u:system_r:hald_t:s0 Target Context system_u:object_r:device_t:s0 Target Objects /dev/dm-15 [ blk_file ] Source hald-probe-volu Source Path /usr/libexec/hald-probe-volume Port <Unknown> Host (removed) Source RPM Packages hal-0.5.13-9.fc12 Target RPM Packages Policy RPM selinux-policy-3.6.32-106.fc12 Selinux Enabled True Policy Type targeted Enforcing Mode Permissive Plugin Name device Host Name (removed) Platform Linux (removed) 2.6.32.10-90.fc12.x86_64 #1 SMP Tue Mar 23 09:47:08 UTC 2010 x86_64 x86_64 Alert Count 1 First Seen Wed 31 Mar 2010 02:07:59 AM EEST Last Seen Wed 31 Mar 2010 02:07:59 AM EEST Local ID fc9ca3e7-84d3-4273-b1a6-52922dae8afb Line Numbers Raw Audit Messages node=(removed) type=AVC msg=audit(1269990479.62:75): avc: denied { ioctl } for pid=6792 comm="hald-probe-volu" path="/dev/dm-15" dev=devtmpfs ino=92651 scontext=system_u:system_r:hald_t:s0 tcontext=system_u:object_r:device_t:s0 tclass=blk_file node=(removed) type=SYSCALL msg=audit(1269990479.62:75): arch=c000003e syscall=16 success=yes exit=0 a0=4 a1=1268 a2=7fffb0dc0e08 a3=7fffb0dc0ac0 items=0 ppid=2077 pid=6792 auid=4294967295 uid=0 gid=0 euid=0 suid=0 fsuid=0 egid=0 sgid=0 fsgid=0 tty=(none) ses=4294967295 comm="hald-probe-volu" exe="/usr/libexec/hald-probe-volume" subj=system_u:system_r:hald_t:s0 key=(null) Hash String generated from device,hald-probe-volu,hald_t,device_t,blk_file,ioctl audit2allow suggests: #============= hald_t ============== allow hald_t device_t:blk_file ioctl;
