Add Cisco Skinny Station protocol support to libalias, natd, and ppp.

2003-09-23T07:41:55Z

Skinny is the protocol used by Cisco IP phones to talk to Cisco Call Managers. With this code, one can use a Cisco IP phone behind a FreeBSD NAT gateway. Currently, having the Call Manager behind the NAT gateway is not supported. More information on enabling Skinny support in libalias, natd, and ppp can be found in those applications' manpages.

A new API function PacketAliasRedirectDynamic() can be used

2003-06-01T23:15:00Z

to mark a fully specified static link as dynamic; i.e. make it a one-time link.

Make the PacketAliasSetAddress() function call optional. If it

2003-06-01T22:49:59Z

is not called, and no static rules match an outgoing packet, the latter retains its source IP address. This is in support of the "static NAT only" mode.

Move IPFW2 definition before including ip_fw.h

2002-07-18T05:18:41Z

Make indentation of new parts consistent with the style used for this file.

Fix a bug caused by dereferencing an invalid pointer when

2002-07-08T22:57:35Z

no punch_fw was used. Fix another couple of bugs which prevented rules from being installed properly. On passing, use IPFW2 instead of NEW_IPFW to compile the new code, and slightly simplify the instruction generation code.

Remove trailing whitespace

The new ipfw code.

2002-06-27T23:02:18Z

This code makes use of variable-size kernel representation of rules (exactly the same concept of BPF instructions, as used in the BSDI's firewall), which makes firewall operation a lot faster, and the code more readable and easier to extend and debug. The interface with the rest of the system is unchanged, as witnessed by this commit. The only extra kernel files that I am touching are if_fw.h and ip_dummynet.c, which is quite tied to ipfw. In userland I only had to touch those programs which manipulate the internal representation of firewall rules). The code is almost entirely new (and I believe I have written the vast majority of those sections which were taken from the former ip_fw.c), so rather than modifying the old ip_fw.c I decided to create a new file, sys/netinet/ip_fw2.c . Same for the user interface, which is in sbin/ipfw/ipfw2.c (it still compiles to /sbin/ipfw). The old files are still there, and will be removed in due time. I have not renamed the header file because it would have required touching a one-line change to a number of kernel files. In terms of user interface, the new "ipfw" is supposed to accepts the old syntax for ipfw rules (and produce the same output with "ipfw show". Only a couple of the old options (out of some 30 of them) has not been implemented, but they will be soon. On the other hand, the new code has some very powerful extensions. First, you can put "or" connectives between match fields (and soon also between options), and write things like ipfw add allow ip from { 1.2.3.4/27 or 5.6.7.8/30 } 10-23,25,1024-3000 to any This should make rulesets slightly more compact (and lines longer!), by condensing 2 or more of the old rules into single ones. Also, as an example of how easy the rules can be extended, I have implemented an 'address set' match pattern, where you can specify an IP address in a format like this: 10.20.30.0/26{18,44,33,22,9} which will match the set of hosts listed in braces belonging to the subnet 10.20.30.0/26 . The match is done using a bitmap, so it is essentially a constant time operation requiring a handful of CPU instructions (and a very small amount of memmory -- for a full /24 subnet, the instruction only consumes 40 bytes). Again, in this commit I have focused on functionality and tried to minimize changes to the other parts of the system. Some performance improvement can be achieved with minor changes to the interface of ip_fw_chk_t. This will be done later when this code is settled. The code is meant to compile unmodified on RELENG_4 (once the PACKET_TAG_* changes have been merged), for this reason you will see #ifdef __FreeBSD_version in a couple of places. This should minimize errors when (hopefully soon) it will be time to do the MFC.
