Description Daniel Black 2011-11-14 09:00:03 UTC
Description of problem:

Fails to connect to AP with the following selinux errors in the log:

Nov 14 15:50:10 spaceman setroubleshoot: SELinux is preventing /usr/sbin/wpa_supplicant from read access on the file /home/dan/.kde/share/apps/networkmanagement/certificates/{5d5d81f2-9c7f-4fd4-90f6-c7ceb6ae49ec}. For complete SELinux messages. run sealert -l 9da65e4e-6ebb-41b1-8016-d6b985d5c488

Version-Release number of selected component (if applicable):
Name        : NetworkManager
Arch        : x86_64
Epoch       : 1
Version     : 0.8.5.92
Release     : 1.git20110927.fc14

Name        : selinux-policy-targeted
Arch        : noarch
Version     : 3.9.7
Release     : 46.fc14

How reproducible:

Always

Steps to Reproduce:
1. Open NetworkManager
2. Create Wireness WPA Enterprise PEAP connect
3. Add custom certificate
  
Actual results:

Disconnection and disassociation

Expected results:

Connection made.

Additional info:

SELinux Network manager module of the form:

module nm 1.0;

require {
        type NetworkManager_t;
        type home_cert_t;
        type cert_t;
        class file { read getattr open };
}

allow NetworkManager_t cert_t:file { read getattr open };
allow NetworkManager_t home_cert_t:file { read getattr open };

With the following added to /etc/selinux/targeted/contexts/files/file_contexts.homedirs
and /etc/selinux/targeted/contexts/files/file_contexts

/home/[^/]*/\.kde/share/apps/networkmanagement/certificates(/.*)? unconfined_u:object_r:home_cert_t:s0

policy/modules/system/userdomain.fc
HOME_DIR/[^/]*/\.kde/share/apps/networkmanagement/certificates(/.*)? gen_context(system_u:object_r:home_cert_t,s0)

Allowing cert_t should allow the user to specify an already installed cert.

Comment 1 Miroslav Grepl 2011-11-14 11:25:11 UTC
Is this a default location?



# chcon -R -t home_cert_t /home/dan/.kde/share/apps/networkmanagement/certificates

should fix the issue. The module should not be needed. 

# sesearch -A -s NetworkManager_t -t home_cert_t -c file -p read
Found 1 semantic av rules:
   allow NetworkManager_t home_cert_t : file { ioctl read getattr lock open }

Comment 2 Daniel Black 2011-11-15 06:16:31 UTC
> Is this a default location?
yes

When it has been imported from kcm_networkmanagement it was copied from where the certificate was (Desktop) to this default location.

Comment 3 Daniel Walsh 2011-11-15 14:38:56 UTC
Fixed in Rawhide with 

14c739f003d9bb11e9b31e2826fb930d5a7d775a


Should be back ported to F15, F16, RHEL6.

Too late for F14.  Since it can be worked around.

Comment 4 Miroslav Grepl 2011-11-21 12:48:20 UTC
It was fixed in selinux-policy-3.10.0-57.fc16

Comment 5 Daniel Black 2011-11-22 10:20:46 UTC
thanks. Was going to move on from F14 very soon.
