Yes. This is just the unix stream socket connected to the pup application. You should upgrade selinux-policy though to a newer policy. pub opens a unix_stream_socket that yum-updated connects to and then sets stdout/stderr/stdin too. When rpm restarts or starts the squid service, the kernel checks if the squid domain can talk to the open file descriptors. It is not allowed so the kernel closes the file descriptors and replaces them with ones connected to /dev/null. These are dontaudited in the latest policy I believe. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.8 (GNU/Linux) Comment: Using GnuPG with Fedora - http://enigmail.mozdev.org iEYEARECAAYFAkeeSTEACgkQrlYvE4MpobMH7QCdE010G6EBQcGxpXfrjvgi42uU 7vAAoNponOTc3uFhxnrSljMRv2TbbHNy =LnnZ -----END PGP SIGNATURE-----
