      Haifux, the Haifa Linux Club (http://linuxclub.il.eu.org) is proud to
      present 'syscalltrack-0.63', the second _alpha_ release of the
      system-call-tracking linux kernel module and user space
      utilities. syscalltrack supports both versions 2.2.x and 2.4.x of
      the linux kernel.

      * What is syscalltrack?

      syscalltrack is a linux kernel module and supporting user space
      environment which allow interception, logging and possibly taking
      action upon system calls that match user defined criteria
      (syscalltrack can be thought of as a sophisticated, system wide
      strace).

      * Where can i get it?

      Information on syscalltrack is available on the project's homepage:
      http://syscalltrack.sourceforge.net, and in the project's file
      release.

      You can download the source directly from:
      http://prdownloads.sourceforge.net/syscalltrack/syscalltrack-0.63.tar.gz

      * Call for developers:

      The syscalltrack project is looking for developers, both for kernel
      space and user space. If you want to join in on the fun, get in touch
      with us on the 'syscalltrack-hackers' mailing list
      (http://lists.sourceforge.net/lists/listinfo/syscalltrack-hackers).

      * License and NO Warrany

      'syscalltrack' is Free Software, licensed under the GNU General Public
      License (GPL) version 2. The 'sct_ctrl_lib' library is licensed under
      the GNU Lesser General Public License (LGPL).

      'syscalltrack' is in early _alpha_ stages and comes with NO
      warranty. If it breaks something, you get to keep all of the
      pieces. You have been warned (TM).

      Happy hacking and tracking!


      Major new features for 0.63
      ---------------------------

      * User defined logging format: it is now possible to define the format
      the log message will take. The default log format is

      syscall: %pid[%comm]: %sid_%sname(%params) (rule %ruleid)

      For example, let us consider an invocation of the 'mkdir' system call:

      syscall: 876[mkdir]: 39_mkdir("foo", 509) (rule 1)

      * Validity checks on system call parameters: sct_config now makes it
      easier to catch rule file erros by making sure that the parameter,
      operand and operator are of matching types. Validity checks are
      implemented for 'param_condition' and 'process_condition' directives
      only.

      * Experimental filter expression: sct_config now allows writing clear,
      concise filter expressions. Here's a filter expression to match a
      system call invocation where the user is root (uid 0) and the first
      parameter contains "passwd":

      filter_expression: (UID == 0) && (PARAMS[1] ~= "passwd")

      (This feature is experimental and does minimal input validation at
      the moment).

      * Support for structure parameters: you can now match system calls
      which get a structure as one of their parameters - for example,
      settimeofday(), which gets a 'struct timeval' and 'struct timezone'
      parameters.

      * Support for (more) process parameters: we now support the following
      process parameters: UID, EUID, SUID, GID, EGID, SGID, PID,
      COMM. Special attention should be given to COMM, which allows matching
      on the name of the program the process is executing.

      * Improved sct_config error diagnostics: sct_config now gives clear,
      concise message on configuration file errors, with line numbers for
      easier rule file debugging.

      * syscalltrack should compile with the latest 2.2 kernel and every 2.4
      kernel, and has been tested with at least 2.2.19, 2.4.5, 2.4.9,
      2.4.10, 2.4.10-ac11 2.4.12, 2.4.12-ac3 and 2.4.12-um3.

      * Additional compilation and run time test programs.

      major bug fixes for version 0.63:

      * memory leaks in the kernel plugged and eradicated.
