| This module attempts to match various characteristics of the packet |
| creator, for locally-generated packets. It is only valid in the |
| .B OUTPUT |
| chain, and even this some packets (such as ICMPv6 ping responses) may |
| have no owner, and hence never match. This is regarded as experimental. |
| .TP |
| .BI "--uid-owner " "userid" |
| Matches if the packet was created by a process with the given |
| effective user id. |
| .TP |
| .BI "--gid-owner " "groupid" |
| Matches if the packet was created by a process with the given |
| effective group id. |
| .TP |
| .BI "--pid-owner " "processid" |
| Matches if the packet was created by a process with the given |
| process id. |
| .TP |
| .BI "--sid-owner " "sessionid" |
| Matches if the packet was created by a process in the given session |
| group. |
| .TP |
| .B NOTE: pid, sid and command matching are broken on SMP |
