| H A D | ipfw2.c | diff 133600 Thu Aug 12 20:06:55 MDT 2004 csjp Add the ability to associate ipfw rules with a specific prison ID. Since the only thing truly unique about a prison is it's ID, I figured this would be the most granular way of handling this. This commit makes the following changes: - Adds tokenizing and parsing for the ``jail'' command line option to the ipfw(8) userspace utility. - Append the ipfw opcode list with O_JAIL. - While Iam here, add a comment informing others that if they want to add additional opcodes, they should append them to the end of the list to avoid ABI breakage. - Add ``fw_prid'' to the ipfw ucred cache structure. - When initializing ucred cache, if the process is jailed, set fw_prid to the prison ID, otherwise set it to -1. - Update man page to reflect these changes. This change was a strong motivator behind the ucred caching mechanism in ipfw. A sample usage of this new functionality could be: ipfw add count ip from any to any jail 2 It should be noted that because ucred based constraints are only implemented for TCP and UDP packets, the same applies for jail associations.
