Description of problem:
Here is what I see when I plug in an iPhone 4S:


Jun 18 07:06:43 tlondon kernel: [ 3654.946228] traps: iphone-set-info[20912] general protection ip:356c40bea6 sp:7fff3a87e450 error:0 in libimobiledevice.so.4.0.1[356c400000+1a000]

and /tmp/root/.config/libimobiledevice/libimobiledevicerc seems not a very secure filename/place to be using: perhaps someplace in /run?

Here are the AVCs:

SELinux is preventing /usr/lib/udev/iphone-set-info from write access on the directory /tmp/.

*****  Plugin catchall (100. confidence) suggests  ***************************

If you believe that iphone-set-info should be allowed write access on the  directory by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# grep iphone-set-info /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

Doing the "permissive" thing, I see this too:

SELinux is preventing /usr/lib/udev/iphone-set-info from create access on the file /tmp/root/.config/libimobiledevice/.

*****  Plugin catchall (100. confidence) suggests  ***************************

If you believe that iphone-set-info should be allowed create access on the  file by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# grep iphone-set-info /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

Comment 1 Bastien Nocera 2013-06-26 10:40:58 UTC
$ rpm -qf /usr/lib/udev/iphone-set-info
libgpod-0.8.2-9.fc19.x86_64

It probably needs updating for the changed API in the unstable releases of libimobiledevice.

Comment 2 Tom London 2013-06-26 13:13:05 UTC
[tbl@tlondon ~]$ rpm -qf /usr/lib/udev/iphone-set-info
