Description Mirek Svoboda 2017-12-01 13:36:14 UTC
Description of problem:
Trying to use IPSEC (strongswan) VPN connection via Gnome UI, with certificates stored at ~/.pki or ~/.cert

My investigation so far is below. My conclusions might be wrong as of my limited selinux knowledge.

Storing certificates at ~/.pki or ~/.cert works for OpenVPN.
OpenVPN arranges that probably via
userdom_read_home_certs(openvpn_t)
which seems to grant home_cert_t to openvpn_t.

We might need the same for ipsec_t, i.e.:
userdom_read_home_certs(ipsec_t)

as charon-nm runs as ipsec_t:
sudo ps -efZ | grep charon-nm
system_u:system_r:ipsec_t:s0    root      5968     1  0 12:08 ?        00:00:00 /usr/libexec/strongswan/charon-nm
SELinux is preventing charon-nm from 'map' accesses on the file /home/mirek/.pki/goodboyKey.der.

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

If you believe that charon-nm should be allowed map access on the goodboyKey.der 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:
# ausearch -c 'charon-nm' --raw | audit2allow -M my-charonnm
# semodule -X 300 -i my-charonnm.pp
