Log information about programs connecting to and disconnecting from the audit netlink multicast socket. This is needed so that during investigations a security officer can tell who or what had access to the audit trail. This helps to meet the FAU_SAR.2 requirement for Common Criteria.

Richard, do you plan to update this to the version you have without perl package dependency? |

I haven't decided. I like the clarity and simplicity of the dependancy, but portability of the open coding.

We would have to disable test on RHEL since perl-Socket-Netlink is not even in EPEL. On the other hand, the test runs on Fedora so I guess the risk of introducing regression in RHEL is very low. However, if you decide to keep perl-Socket-Netlink you will have to update tests/Makefile to filter-out new test on RHEL. |

@pcmoore Would you consider taking this branch instead? The commented-out code provides a method to verify that the pack operation was correct. |
In order to simplify things @rgbriggs, update this PR (or close and replace it with another, your choice) with what you would like me to review. One PR with comments on multiple submissions is awkward. |

See #99 |
