Hi Jeff,

We still work on this pull request and it's not completely finished, but we made some progress on this issue, so you can try, what we investigated.

Please create file mynetworkmanager.te 

where you copy this:

$cat mynetworkmanager.te

policy_module(mynetworkmanager, 1.0)

require {
	type NetworkManager_ssh_t;
 
	
}

#=============NetworkManager_ssh_t==============

userdom_rw_user_tmp_sock_files(NetworkManager_ssh_t)



you have to install selinux-policy-devel if don't have it installed on your system
then you compile this file, please use in dir where you have mynetworkmanager.te
$make -f /usr/share/selinux/devel/Makefile mynetworkmanager.pp

and finally load module to kernel, please use
#semodule -i mynetworkmanager.pp


it should work now for you. Or you have still AVC's related with NetworkManager_ssh_t?

Thanks,
Patrik

SELinux is preventing sh from read access on the file /usr/sbin/ifconfig.

Plugin: catchall 
 SELinux denied access requested by sh. It is not expected that this access is
required by sh and this access may signal an intrusion attempt. It is also
possible that the specific version or configuration of the application is
causing it to require additional access.

If you believe that sh should be allowed read access on the ifconfig file by default.
You should report this as a bug.
You can generate a local policy module to allow this access.
Allow this access for now by executing:
# ausearch -c 'sh' --raw | audit2allow -M my-sh
# semodule -X 300 -i my-sh.pp

when I apply the above, I still get a connection failed, but no additional AVCs.

SELinux is preventing sh from 'read, open' accesses on the file /usr/sbin/ifconfig.
