Did this start appearing recently after updating the icecream package? What version of icecream is this? When does this appear? During iceccd startup? Or when trying to build a project using iceccd? Or when iceccd processes build requests from other machines? I see comm is "ldd". Only icecc-create-env should run ldd. But that's supposed to run under context iceccd_createenv_t, not iceccd_t. The problem is icecc-create-env was moved from /usr/libexec to /usr/bin, but the policy was not changed and the script is now mislabeled. I'll fix this. Yes, it started happening recently, maybe few weeks ago. icecream-1.0.1-9.20140822git.fc19.x86_64 It happens first time I run g++ for a local build. After that it won't happen until system is rebooted. *** Bug 1173522 has been marked as a duplicate of this bug. *** *** Bug 1173523 has been marked as a duplicate of this bug. *** *** Bug 1173525 has been marked as a duplicate of this bug. *** Installing the 64-bit RPM from koji (comment 7) results in another SELinux message.
