Additional info:
SELinux is preventing starter from execute_no_trans access on the file /usr/libexec/strongswan/charon.

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

If you believe that starter should be allowed execute_no_trans access on the charon 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 'starter' --raw | audit2allow -M my-starter
# semodule -X 300 -i my-starter.pp

Still present:

selinux-policy-3.13.1-259.fc26.noarch
strongswan-5.5.3-1.fc26.x86_64

Comment 2 Jari Turkia 2017-08-31 08:22:11 UTC
This my local policy to make StrongSWAN work again:

module local 1.0;

require {
        type ipsec_t;
        type ipsec_exec_t;
        type var_run_t;
        class file { execute_no_trans };
        class sock_file { unlink write };
}

#============= ipsec_t ==============
allow ipsec_t ipsec_exec_t:file execute_no_trans;
allow ipsec_t var_run_t:sock_file { unlink write };

Comment 3 Fedora End Of Life 2018-05-03 08:32:17 UTC
This message is a reminder that Fedora 26 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 26. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as EOL if it remains open with a Fedora  'version'
of '26'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version.

Thank you for reporting this issue and we are sorry that we were not
able to fix it before Fedora 26 is end of life. If you would still like
to see this bug fixed and are able to reproduce it against a later version
of Fedora, you are encouraged  change the 'version' to a later Fedora
version prior this bug is closed as described in the policy above.

Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.
