Subject: IpTables ROPE 20050426 - packet match rule scripting language
A new version of "Rope" has been released. Changes since the last
announcement include...
. Minor fix to Bittorrent identification script (bittorrent.rope)
. Compiled script files are now security checked before being loaded
into the kernel (they MUST be owned by root, and be writable by no-one
else).
ROPE is a scritable packet match module for Linux iptables / Netfilter. It
allows packet matching criteria to be written using a simple scripting
language which is executed in and by the Linux kernel.
It is available under the GPL from http://www.lowth.com/rope.
A simple example :- a rule that limits the size of pages downloaded over
HTTP based on the Content-Length header could prevent long downloads
before they even start. Here's a trivial ROPE script to provide this
logic...
$tcp_source 80 eq assert # check that it's HTTP
expecti_to( "Content-Length: " ) # find the header
expect_while({isdigit}) put($n) # lift the length value
if( atoi($n) 1000000 gt { yes } ) # match: if too long
no # dont match: if not
If this script is stored as "contlen.rope" and compiled as "contlen.rp",
then it can be installed into an Iptables chain using a command like.
iptables -A FORWARD -m rope --rope-script contlen -j DROP
For more information (including a more thorough version of the example
script), please refer to:

Subject: Cxref - C program cross-referencing & documentation tool
Date: 2 May 2005 05:50:01 GMT
C Cross Referencing & Documenting tool. Version 1.6a - cxref
============================================================
Cxref is a program that will produce documentation (in LaTeX, HTML, RTF or SGML)
including cross-references from C program source code.
Works for ANSI C, including most gcc extensions.
The documentation for the program is produced from comments in the code that
are appropriately formatted. The cross referencing comes from the code itself
and requires no extra work.
The documentation is produced for each of the following:
Files - A comment that applies to the whole file.
Functions - A comment for the function, including a description of
each of the arguments and the return value.
Variables - A comment for each of a group of variables and/or
individual variables.
#include - A comment for each included file.
#define - A comment for each pre-processor symbol definition, and
for macro arguments.
Type definitions - A comment for each defined type and for each element of a
structure or union type.
Any or all of these comments can be present in suitable places in the
source code.
The cross referencing is performed for the following items
Files - The files that the current file is included in
(even when included via other files).
#includes - Files included in the current file.
- Files included by these files etc.
Variables - The location of the definition of external variables.
- The files that have visibility of global variables.
- The files / functions that use the variable.
Functions - The file that the function is prototyped in.
- The functions that the function calls.
- The functions that call the function.
- The files and functions that reference the function.
- The variables that are used in the function.
Each of these items is cross referenced in the output.
Includes extensive README and FAQ with details and examples on how to use the
program.
Changes
=======
Since version 1.6:
Bug fixes
Added function prototypes to allow cxref-cpp to work on 64-bit machines.
Fix bug reading from freed memory and small memory leak.
Stop comments intended for functions appearing on #defines inside function.
If cxref-cpp cannot find include directory from cxref-cpp.defines then abort.
Fix installation of manual page.
Parsing changes
Allow variable declaration in for(;;) statements.
Allow named initialisation of structure/union using named initialisers.
Fix bad handling of some vararg macros in cxref-cpp.
Availability
============
Previous versions of this program have been tested on the following systems:
Linux 1.[123].x, Linux 2.[01234].x, SunOS 4.1.x, Solaris 2.x, HPUX 10.x
