Change Log

All relevant changes to the project are documented in this file.

v3.3 - 2019-03-23

Fixes

  • Fix #5: Use stdout, not stderr, for --version and --usage
  • Fix #6: Minor typo in man page
  • Fix #8: Update build instructions in README
  • Fix #9: Major timing bug fix in --max-bandwidth and --random-wait. Delays below one second are off by a factor 1000!

v3.2 - 2018-03-10

Minor bug fixes.

Changes

  • Add missing transproxy.txt file to distribution
  • Update usage text and man page for --bind option, w.r.t. transproxy

Fixes

  • Issue #4: Service names from /etc/services not recognized for compat syntax, --lport or --cport

v3.1 - 2017-01-22

Restored support for some command line options on behalf of Debian.

Changes

Fixes

  • Portability fixes for musl libc

v3.0 - 2016-05-06

This version changes the command line syntax! You are going to have to change how you call redir in order to upgrade.

Changes

  • Convert SRC:PORT and DST:PORT from options to arguments, using a UNIX syntax that is pretty much standard by now.
  • Rename -n,--name=STR --> -I,--ident=NAME
  • Simplify argument parsing, move more data to global variables
  • Simplify debug() statements, use syslog()
  • Daemonize by default, like a proper UNIX daemon, unless -n, --foreground is given
  • Replace perror() and other log messages going to stderr in favor of syslog() for everything, unless running in foreground, in which case we use LOG_PERROR for log message output to stderr as well ... unless -s, --syslog is given
  • Replace -d, --debug with -l, --loglevel=LEVEL to control the syslog() default log level. The default log level is LOG_NOTICE
  • Convert to GNU Configure & Build System. With configure switches like --disable-ftp, --disable-shaping, and --with-libwrap
  • Change distribution to use .tar.xz rather than .tar.gz from now on
  • Convert to Markdown, clean up and simplify README
  • Remove local versions of getopt() and getopt_long(). All relevant UNIX distributions should have them by now.
  • Massive code cleanup and (Linux KNF) coding style fixes
  • Add Coverity Scan support for Travis-CI runs
  • Complete rewrite of man page
  • Overhaul of --help usage help
  • Refactor to reduce code duplication:
    • verify_request() for TCP wrapper handling
    • target_init() for initializing a struct sockaddr_in
    • target_connect() to handle creating and connecting a target socket
  • Refactor to harmonize function and variable names
  • Cleanup redir.c heading and use proper GNU GPL blurb
  • Make sure to credit all known major contributors in AUTHORS file
  • Removed redir.lsm file

Fixes

  • Fix socket leaks found by Coverity Scan
  • Fix unterminated strings returned by read(), found by Coverity Scan
  • Fix ordering bug(s) found by Coverity Scan
  • Fix strcpy() into fixed size buffer found by Coverity Scan
  • Fix uninitialized struct sockaddr_in, found by Coverity Scan
  • Check malloc() return value
  • Do gethostbyname() before every connect(), DNS names may change at runtime

v2.3 - 2016-05-01

This is a checkpoint release by the new maintainer, Joachim Wiberg, integrating all (most) of Debian's patches.

Changes

  • Rename man page redir.man --> redir.1
  • Rename CHANGES --> ChangeLog.md
  • Update Linux Software Map, v0.7 --> v2.2
  • Don't strip binaries by default. Thanks to Julien Danjou.
    Closes Debian bug #437898, by Daniel Kahn Gillmor
  • Clean up questionable formatting in man page, by Daniel Kahn Gillmor
  • Remove overrides in Makefile to enable hardening, by Tobias Frost

Fixes

  • Debian fixes to man page and --help text for --max_bandwidth
    by Daniel Kahn Gilmor
  • Use ntohs() to generate comprehensible debug()s and syslog()s,
    by Bernd Eckenfels
  • Fix calls to TCP wrappers, by Daniel Kahn Gillmor
  • Fix timeouts to only happen after full duration of inactivity, rather than absolute. This patch is a close approximation of Robert de Bath's patch for Debian bug #142382, by Daniel Kahn Gillmor
  • Build without any warnings from gcc, even with --pedantic, patch by Daniel Kahn Gillmor
  • Fix problem with buffer allocation introduced by bandwidth throttling. Closes Debian bug #335288, by Daniel Kahn Gillmor
  • Cosmetic fixes to man page which could be applied upstream.
    by Daniel Kahn Gillmor
  • Ensure that the server socket has SO_REUSEADDR and SO_LINGER set properly. Closes Debian bug #508140, by Daniel Kahn Gillmor
  • Handle type casting of variables. Change size_t variables to instead use socklen_t, warning from gcc. Fix by Lucas Kanashiro

v2.2.1 - 1999-12-26

Bug fix relase by Sam Creasey.

Changes

  • Support for traffic shaping by Emmanuel Chantréau. Interesting stuff. I've not tested this in detail personally.
  • Adds the ability to compile redir with lesser functionality for speed. This is documented in the README.

Fixes

  • Fix bug in do_accept() where non-fatal error codes returned by accept() would cause redir to terminate entirely. I had recieved reports of this behavior but was unable to find it until sammy.net had to handle the load of the redir 2.2 update using redir :)
    All non-fatal error codes might not be covered. But it "got better".

v2.2 - 1999-12-15

Changes

  • Support for redirecting PORT mode FTP connections in addition to PASV mode FTP redirection. Thus --ftp is now --ftp={port,pasv,both} to determine what should be redirected. The original version of this patch was submitted by Harald Holzer
  • Adds the --connect option, which is useful if you're bouncing your connections through an HTTP proxy server. Use as --connect=host:port and this will be the CONNECT line sent to the proxy.

v2.1 - 1999-06-22

Bugfix release

Fixes

  • Fix a problem with FTP redirection
  • Fix (and add) various logging messages
  • Fix for some of the TCP wrappers code

v2.0 - 1999-02-11

This version changes the command line syntax! You're going to have to change how you call redir in order to upgrade, but not by all that much. We now use --options for everything, instead of having the rather wonky "if you've got this thing here, something happens" method used before. We apologize for the inconvenience, but this is really a lot less brain damaged.

Changes

  • Support for TCP wrappers, thanks to Damien Miller
  • The --name option now sets the TCP wrapper service name as well as the syslog program name, making it possible to run multiple instances of redir with different access controls. Edit the Makefile to enable TCP wrappers.
  • Actually implement --transproxy when running from inetd.
  • Cleaned up --ftp support, at least a little. There are probably still improvements to be made here, but, alas.

v1.2 - UNKNOWN

Like v0.5, this release was not possible to locate on the Internet anymore. Even using excellent help from http://www.archive.org. Restoring this change set was not possible, all we have is this change log entry. If you know the release date, please contact me --Joachim

Changes

  • Adds the option --transproxy, which, when run as super-user on a Linux system which has had transparent proxying compiled into it's kernel, will make connections seem as if they had come from their true origin. See transproxy.txt for further discussion of this option

Fixes

  • redir should now compile and run correctly on systems which lack getopt_long()

v1.1 - 1998-10-31

Changes

  • Add the option --ftp, which, when redirecting a port to an FTP server, will, when the server wants to initiate a passive connection, redirect another port for that connection

v1.0 - 1998-08-08

This is the first release by Sam Creasey after picking up from v0.7 by Nigel Metheringham.

Changes

  • Add the option --bind-addr, which can force redir to bind to a specific address or interface when making outgoing connections

v0.7 - 1998-06-30

A cleanup and bug fix release by Nigel Metheringham after the initial v0.5 release by Sam Creasey.

v0.5 - UNKNOWN

This release was not possible to locate on the Internet anymore, but is the initial release by Sam Creasey. In his own words:

Redir is actually a horrible hack of my other cool network utility, daemon, which is actually a horrible hack of ora's using C sample code, 12.2.c. But, hey, they do something. (and that's the key.)
