Using the pf firewall it's possible to add the "user" parameter on the log
command to have the UID in the additional information of packets shown on
pflogX interface.
On MacOS (I can't say about BSD) the UID field seems to me that is Little
endian but it's decoded as it would be Big Endian.



PS: there are also the PID, the RULE UID and the RULE PID fields, but I think
that they are not populated correctly (by pf).
