Description Ed Marshall 2017-11-30 22:28:41 UTC
Description of problem:
Created an IPsec VPN via gnome network control panel.
SELinux is preventing charon-nm from 'map' accesses on the file /etc/pki/tls/certs/Makefile.

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

If you believe that charon-nm should be allowed map access on the Makefile 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

Comment 1 Ed Marshall 2017-11-30 22:32:14 UTC
It's not just the Makefile, although fixing for that will fix for the rest as well:

Nov 30 14:27:12 localhost.localdomain audit[17101]: AVC avc:  denied  { map } for  pid=17101 comm="charon-nm" path="/etc/pki/ca-trust/extracted/pem/tls-ca-bundle.pem" dev="dm-1" ino=394791 scontext=system_u:system_r:ipsec_t:s0 tcontext=system_u:object_r:cert_t:s0 tclass=file permissive=0
Nov 30 14:27:12 localhost.localdomain audit[17101]: AVC avc:  denied  { map } for  pid=17101 comm="charon-nm" path="/etc/pki/ca-trust/extracted/openssl/ca-bundle.trust.crt" dev="dm-1" ino=394787 scontext=system_u:system_r:ipsec_t:s0 tcontext=system_u:object_r:cert_t:s0 tclass=file permissive=0
Nov 30 14:27:12 localhost.localdomain audit[17101]: AVC avc:  denied  { map } for  pid=17101 comm="charon-nm" path="/etc/pki/tls/certs/Makefile" dev="dm-1" ino=400186 scontext=system_u:system_r:ipsec_t:s0 tcontext=system_u:object_r:cert_t:s0 tclass=file permissive=0

Reproducing is pretty easy: just open gnome network settings, add a new "IPsec/IKEv2 (strongswan)" VPN, and in my case, pick certifcate/ssh-agent, but it looks like this is going to happen regardless of how you configure the client.

Comment 2 Robert Jones 2017-12-03 08:55:40 UTC
I also have the same issue accessing a gateway certificate located in ~/.cert despite correct labelling of the certificate. In fact this certificate wasn't in ~/.cert it was in ~/ but I moved it there following the advice of a similar bug report 2nd November.

Now.. this *was* working OK until "recently" so I downgraded selinux-policy thinking this to be the breaking update, however this didn't make it all start working again. I got Networkmanager-strongswan to connect again by following the advice from 'catchall' but not sure if this is the correct solution long term?:

SELinux is preventing charon-nm from map access on the file /home/robert/.cert/gatewaycert.pem.
