Hey Juan

I'm troubleshooting the radicale policy but I cannot

figure

why the service fails to transition to radicale_t. It

runs in

the init_t domain.

  How you starting this service?

systemctl start radicale.service

I cannot find where is the problem, I see other daemons are
also
using init_daemon_domain. Why mine is it not transitioning?

What's in your unit file? Certain systemd options can prevent
SELinux
transitions or disable SELinux functionality (e.g.
NoNewPrivileges,
ProtectKernelTunables).

# /usr/lib/systemd/system/radicale.service
[Unit]
Description=Radicale CalDAV and CardDAV server
Documentation=http://radicale.org/documentation/
After=network-online.target
Requires=network-online.target

[Service]
WorkingDirectory=/var/lib/radicale
User=radicale
Group=radicale
UMask=0027
Type=forking
PIDFile=/var/run/radicale/radicale.pid

pid=/var/run/radicale/radicale.pid
PrivateTmp=true
PrivateDevices=true

ProtectHome=true

[Install]
WantedBy=multi-user.target

systemd version?

I'm guessing that one of the above options is automatically enabling
NoNewPrivileges=yes and needs to be disabled.  Note to Fedora SELinux
maintainers: something needs to be done about systemd and its
handling
of NoNewPrivileges and ProtectKernelTunables, or we can only expect
more instances of such breakage...

Looks like it is PrivateDevices=true.

Check out

https://bugzilla.redhat.com/show_bug.cgi?id=1412696

There the PrivateDevices=true, in combination with selinux, caused postfix to quit unexpectedly.

​That is the answer, thank you very much.

Is it a bug?​
