I tested this on Fedora 22 and did not get a USER_AVC from dbus, but I also did not get an error message in syslog. So, I don't know what to make of it. (And for the record, I have a bz open saying that USER_AVC is the wrong event type. They are blaming libselinux but I blame them for not using AUDIT_USER_MAC_POLICY_LOAD.) -Steve > > I guess I have to ask which kernel too, since changes to NET and PID > > namespaces are somewhat recent and Debian tends on the side of > > conservative to be stable. > > I'm under debian unstable and the kernel I'm running is 4.2 > > >>> I've been to reproduce this on F23 as well. > >> > >> I have not played around with that yet. > > > > What kernel is that? > > 4.2 too apparently. > > Cheers, > > Laurent Bigonville > > -- > Linux-audit mailing list > [email protected] > https://www.redhat.com/mailman/listinfo/linux-audit -- Linux-audit mailing list [email protected] https://www.redhat.com/mailman/listinfo/linux-audit
