# $Id: ChangeLog 1162 2007-01-06 23:51:02Z benoitg $
2007-01-06 Benoit Grégoire  <bock@step.polymtl.ca>
        * Documentation update in the code
        * Released 1.1.3_beta6

2006-10-26 Benoit Grégoire  <bock@step.polymtl.ca>
        * src/conf.h: Fix #238 by using $sysconfdir to compute the default config-file location.
        
2006-10-08 Alexandre Carmel-Veilleux <acv@miniguru.ca>
        * Changed my email in a few files.
        * Broken down some printf's on multiple lines.
        * Added comments.

2006-09-14 Benoit Grégoire  <bock@step.polymtl.ca>
        * src/util.c, src/conf.h: Fix autodectection of the External interface if not specified in the config file.  If the interface (typically pppoe) wasn't yet fully up when wifidog starts, wifidog would stop every connection from going trough.  It will now retry every second for up to two minutes, and then exit with a fatal error if it can't successfully detect it.

2006-02-23 Philippe April <philippe@ilesansfil.org>
        * src/fw_iptables.c:
        * Changed order in the filter.FORWARD chain
        * Added TCPMSS rule
        * Fixed deleting the rules on shutdown
        * Fixed wdctl reset problem
        * Released 1.1.3_beta4

2006-02-06 Benoit Grégoire  <bock@step.polymtl.ca>
        * src/fw_iptables.c: Fix deleting the rules on shutdown.

2006-01-31 Benoit Grégoire  <bock@step.polymtl.ca>
        * Release 1.1.3_beta2
        
2006-01-31 Benoit Grégoire  <bock@step.polymtl.ca>
        * src/fw_iptables.c:  Add the global ruleset to the nat table to fix #65.
        Add the table parameter to iptables_load_ruleset() and iptables_compile
        * libhttpd/protocol.c:  Fix pointer type mismatch
    * src/conf.c,h:  Remove deprecated option AuthServMaxTries (which was already ignored anyway.       
        
2006-01-23 Benoit Grégoire  <bock@step.polymtl.ca>
        * src/conf.h:  Fix the value of DEFAULT_AUTHSERVPATH and completely wrong code comment.  Not the default indicated in the config file and the define are in sync.

2006-01-17 Mina Naguib <mina@ilesansfil.org>
        * Ingisgnificant cleanup  of CVS artifacts after svn migration

2005-11-24 Philippe April <philippe@ilesansfil.org>
        * Bad idea

2005-11-01 Max Horvath <max.horvath@maxspot.de>
        * Added .project to .cvsignore

2005-11-01 Philippe April <philippe@ilesansfil.org>
        * Added OPTIONS section in wifidog-init (example: enable syslog)

2005-10-09 Philippe April <philippe@ilesansfil.org>
        * Changed html pages, added info to wdctl status

2005-10-07 Philippe April <philippe@ilesansfil.org>
        * Released 1.1.3_beta1

2005-10-03 Philippe April <philippe@ilesansfil.org>
        * libhttpd: Fixed two bugs parsing the GET query string making wifidog segfault

2005-09-24 Mina Naguib <mina@ilesansfil.org>
        * New wdctl command "restart" which will get wifidog to restart itself
        while preserving the existing clientlist.  Perfect for 0-downtime
        upgrading!
        * safe.c: New safe_fork that croaks if the fork fails, also takes care of
        closing some global file descriptors for the child
        * debug.c: Now also logs the PID as part of every entry
        * gateway.c: Handler for SIGCHLD now waitpid()s with WNOHANG flag to prevent deadlock
        when the handler is called and another wait() or waitpid() is used
        * util.c: execute() now uses waitpid() instead of wait() to reap only the child
        it fork/executed
        * Extra debugging entries throughout code

2005-09-24 Mina Naguib <mina@ilesansfil.org>
        * conf.c: Pre-emptive bugfix - harsh lockdown of parsing trusted MAC
        addresses from config file

2005-09-24 Philippe April <philippe@ilesansfil.org>
        * (finally) Added {Saul Albert,Jo Walsh,Schuyler}'s patch (thank you!) to send
        the GW interface's mac address as the node_id if no node_id is specified. It allows
        the use of generic configuration files without the need to hardcode the
        node_id in.
        * Added TrustedMACList configuration variable which allows specifying
        MAC addresses which are allowed to go through without authentication.
        * Updated OpenWrt instructions.

2005-09-08 Philippe April <philippe@ilesansfil.org>
        * Added compile instructions and installation for OpenWrt Whiterussian-rc2
        * Released 1.1.2

2005-05-30 Mina Naguib <mina@ilesansfil.org>
        * New wdctl command "restart" which will get wifidog to restart itself while preserving the existing clientlist.  Perfect for 0-downtime upgrading!
        * safe.c: New safe_fork that croaks if the fork fails, also takes care of closing some global file descriptors for the child
        * debug.c: Now also logs the PID as part of every entry
        * gateway.c: Handler for SIGCHLD now waitpid()s with WNOHANG flag to prevent deadlock when the handler is called and another wait() or waitpid() is used
        * util.c: execute() now uses waitpid() instead of wait() to reap only the child it fork/executed
        * Extra debugging entries throughout code
        
2005-05-24 Mina Naguib <mina@ilesansfil.org>
        * wdctl.c: Minor bugfix pointed out by David Vincelli: When an invalid
        command is given to wdctl, the error message showed "Invalid command:
        wdctl" instead of the actual command supplied

2005-05-23 Philippe April <philippe@ilesansfil.org>
        * Released 1.1.2_pre1

2005-05-23 Mina Naguib <mina@ilesansfil.org>
        * fw_uptables.c: When appending call to chain WiFiDog_Outgoing from
        nat.prerouting, add it via -A (at end) instead of -I 1 (at beginning) to
        allow for existing nat forwarding.

2005-05-16 Mina Naguib <mina@ilesansfil.org>
        * centralserver.c: read()s from central server in auth_server_request() are
        now timed-out (via select).  This is hopefully a bugfix to the
        thread-freezing problem.

2005-05-06 Mina Naguib <mina@ilesansfil.org>
        * Bugfix non-RFC compliant HTTP requests using \n instead of \r\n as line
        terminations as per email from ludocornut@users.sourceforge.net

2005-04-28 Philippe April <philippe@ilesansfil.org>
        * Released 1.1.2_beta2

2005-04-28 Mina Naguib <mina@ilesansfil.org>
        * wifidog.conf: Make the default ruleset for validating users = allow all
        (except sending SMTP)

2005-04-20 Philippe April <philippe@ilesansfil.org>
        * fw_iptables.c: Insert ourselves at the end of filter.FORWARD instead of
        at the beginning since important FW instructions are located there on the
        WRT54Gs when used with some DSL providers and we never execute them
        otherwise.
        * Released 1.1.2_beta1

2005-04-03 Philippe April <philippe@ilesansfil.org>
        * Fixed issue with FAQ
        * ipkg/rules: If autogen.sh doesn't exist, it's ok. 'configure' will.

2005-04-01 Philippe April <philippe@ilesansfil.org>
        * Duplicated auth server list in NAT table to fix the issue
        of using an auth server on port 80, since port 80 was being systematically
        redirected to 2060 otherwise.
        * Released 1.1.1

2005-03-29 Mina Naguib <mina@ilesansfil.org>
        * Added FAQ document copied from wiki

2005-03-22 Philippe April <philippe@ilesansfil.org>
        * Released 1.1.0

2005-03-20 Mina Naguib <mina@ilesansfil.org>
        * More verbose debugging output

2005-03-12 Mina Naguib <mina@ilesansfil.org>
        * More debugging output
        * Document ugly hack involving tid_fw_thread
        * SIGPIPE now ignored (as it's comment said) instead of being sent to the
        handler for SIGCHLD
        * Bugfix firewall destruction not happening from termination handler - had
        to move explicit thread kills after, not before, firewall destruction

2005-03-11 Mina Naguib <mina@ilesansfil.org>
        * If external interface was unspecified in the conf file, try to determine
        it from the default route
        * If external interface is known, specify it in the trigger rule in
        nat.PREROUTING to prevent the rule from matching traffic inbound to the
        router itself.  This should fix the issue raised by Philippe and Pascal on
        the mailing list
        * Bugfix: UNDO ABOVE 2 ITEMS. Aparently you cannot use the "-o" iptables
        option in nat.PREROUTING which makes knowing external_interface useless
        * Added new chain in nat.PREROUTING that explicitly allows all traffic to
        the router's internal IP from the internal interface, effectively
        addressing the same above problem

2005-03-07 Mina Naguib <mina@ilesansfil.org>
        * auth.c: Got rid of legacy _http_output and _http_redirect - replaced them
        with libhttpd functions and http_wifidog_header/http_wifidog_footer
        * auth.c: When re-directing to auth server now respects SSL setting instead
        of always http+port 80
        * auth.c: Better debugging output of what it's doing when it acts on auth
        server response
        * A little bit more care with buffers and their sizes
        * Minor whitespace tweaking and a couple of internal doc typo fixes

2005-03-06 Mina Naguib <mina@ilesansfil.org>
        * Check return values of pthread_create
        * Internal documentation touch-ups
        * auth.c: Bugfix invalid http header sent by _http_output
        * Bugfix traffic counter read from iptables as long int instead of long
        long int
        * Minor insignificant code touch-ups:
                * Replace pthread_mutex_lock/unlock calls with appropriate
                LOCK_FOO/UNLOCK_FOO macros for consistency
                * Lock first before using some variables, not after
                * Indentation adjustments

2005-03-04 Mina Naguib <mina@ilesansfil.org>
        * Bugfix huge uptime pointed out to be by Philippe - was caused when the
        date is set (with ntpclient for example) after wifidog starts
        * Beautified "Uh oh!" apology screens and redirection screen

2005-03-02 Alexandre Carmel-Veilleux <acv@acv.ca>
        * Ifdef'd out the bits that are Linux specific if __linux__ is not
          defined.

2005-03-01 Mina Naguib <mina@ilesansfil.org>
        * Minor visual tweaks to the web interface

2005-03-01 Philippe April <philippe@ilesansfil.org>
        * Tagged v1_1_0_beta3

2005-02-28 Mina Naguib <mina@ilesansfil.org>
        * Do not update the last_updated field on incoming traffic - update it on
        outgoing traffic only.  This should be a much more reliable indication of
        client no longer being there
        * WifiDog status is now viewable with a web browser at
        http://ip:port/wifidog/status
        * Added new web hook for http://ip:port/wifidog
        * Beautified web interface at http://ip:port/wifidog/*

2005-02-24 Mina Naguib <mina@ilesansfil.org>
        * auth_server_request now returns AUTH_ERROR on error instead of AUTH_VALIDATION_FAILED
        * centralserver.c: Fix typo (was =+, made it +=) that made the response
        from the auth server corrupted in memory if the entire response would not
        fit in 1 packet and retrieved with 1 read() call
        * Better logging of details and calling of mark_* (auth+online/offline)

2005-02-22 Philippe April <philippe@ilesansfil.org>
        * Tagged v1_1_0_beta2

2005-02-20 Mina Naguib <mina@ilesansfil.org>
        * New safe.c with safe_malloc, safe_strdup, safe_asprintf and
        safe_vasprintf with propper logging and exit when error. Replaced all
        instances of original with safe versions in all files
        * Fix memory leak in iptables_fw_counters_update
        * Partial merge from CaptiveDNS branch: Consolidated much of the networking
        calls to the auth servers into a magical function called connect_auth_server()
        that's responsible for dns lookup, connecting, marking servers bad, marking
        online/auth_online, and refreshing the firewall rules.
        * Partial merge from CaptiveDNS branch: Added new functions mark_auth_online(),
        mark_auth_offline() and is_auth_online() - similar in nature to is_online()
        etc. except tailored to decide on auth servers status - currently being called by
        connect_auth_server()
        * Partial merge from CaptiveDNS branch: Different apology in 404 handler
        depending on whether internet is down or just auth server is down
        * Partial merge from CaptiveDNS branch: wdctl status now shows status of
        is_online and is_auth_online
        * Fixed several inconsistencies regarding the parity and size of
        incoming/outgoing counters.  Standardized on "unsigned long long int" in
        declarations and *printf/*scanf formats

2005-02-16 Philippe April <philippe@ilesansfil.org>
        * ipkg/rules - When we clean, forgot to delete ipkg-build-stamp

2005-02-15 Mina Naguib <mina@ilesansfil.org>
        * Now also reports wifidog_uptime when it pings the server, as well as
        shows it in wdctl status

2005-02-13 Mina Naguib <mina@ilesansfil.org>
        * Completely re-did the iptables rules.  Most of the rules are now in the
        filter table instead of the nat table.  Also DROPs are now replaced with
        REJECTs to help tell the user connection refused instead of endless pauses
        * Bugfix: Traffic from client to router was counted twice in the "outgoing"
        bytecount since it increased both counters in mangle.* and filter.* - Got
        rid of TABLE_WIFIDOG_WIFI_TO_GW completely since it's unneeded

2005-02-12 Mina Naguib <mina@ilesansfil.org>
        * Stricter format rules for all *scan* functions hunting for IPs and MAC addresses
        * fw_iptables.c: Make sure scanned IP address is a valid IP address
        * firewall.c: Fix memory leak in arp_get
        * libhttpd/protocol.c: Abort connection if read non-ascii from client. This
        is often a telltale sign of a program such as skype using port 80 for
        non-http requests - this therefore ends the thread as early as possible
        instead of having it lay around for a while trying to get a valid http
        request and taking up resources
        * ping_thread.c: When pinging auth server now also sends sys_uptime, sys_memfree
        and sys_load
        * -v commandline option now shows wifidog version

2005-02-11 Philippe April <philippe@ilesansfil.org>
        * Tagged v1_1_0_beta1

2005-02-11 Philippe April <philippe@ilesansfil.org>
        * Fixed a bug in counting the traffic between client and gateway
        * Alpha8

2005-02-04 Mina Naguib <mina@ilesansfil.org>
        * Partially bugfix apology when offline
        * ipkg/rules: More tweaking to make it build nicely with recent openwrt
        buildroots

2005-02-03 Mina Naguib <mina@ilesansfil.org>
        * Keep track of last times we successfully & unsuccessfully spoke to the
        auth server/used DNS. Then, if we know we're not online, show a little
        apology to the user instead of re-directing them to the auth server.
        * ipkg/rules: Added some extra version detection to auto-detect versions
        of kernel, iptables and ipkg-utils instead of having them hardcoded.  This
        makes creating ipkg's work with different OpenWRT releases
        * fw_iptables.c: Fixed memory leak caused by not freeing return from
        iptables_compile in iptables_load_ruleset
        * http.c: Deleted unused call to client_list_find
        * http.c: /about URL now shows wifidog version
        * Cosmetic typo fixes

2005-02-03 Philippe April <isf_lists@philippeapril.com>
        * Ping the users everytime we check their counters, that way we keep them
        alive
        * Optional ExternalInterface
        * Optional GatewayAddress (we discover it. finally.)
        * We check for the traffic from the clients to the firewall, to catch the
        traffic the icmp ping is generating
        * Fixed bug where we were doing the opposite of what desired when checking if authentication server was alive
        * Bumped to alpha7

2005-01-23 Philippe April <isf_lists@philippeapril.com>
        * wdctl status will return the auth servers in the linked list
        * We'll now forward to the auth server to display the used-to-be-ugly
        messages like "go ahead and validate your account you have 15 minutes"
        * Bumped to alpha6

2005-01-06 Philippe April <philippe@philippeapril.com>
        * fw_iptables.c: Changed REJECT to DROP for the end of the table Unknown,
          REJECT doesn't seem to be available in the NAT table.
        * fw_iptables.c: Indented things
        * fw_iptables.c Fix: Created the authservers table at the beginning and destroy
          at exit time only to avoid recreating it everytime
        * Bumped to alpha5

2005-01-05 Philippe April <philippe@philippeapril.com>
        * Typo, fixed some spaces (mostly esthetic)
        * Bumped to alpha4

2004-12-19 Alexandre Carmel-Veilleux <acv@acv.ca>
        * src/fw_iptables.c: Tweak of auth_server firewall rule setting
          code. (and promptly undone, fixing the cause is better then
          fixing the symptom)
        * src/conf.c: NULL-fill auth_server struct so that
          auth_server->last_ip always equals NULL when first filled.

2004-12-16 Benoit Grégoire  <bock@step.polymtl.ca>
        * src/fw_iptables.c: Display iptables command that is run in debug mode.
        
2004-12-07 Benoit Grégoire  <bock@step.polymtl.ca>
        * src/firewall.c: Fix reversed incoming and outgoing connections in statistics code
        * bump version to alpha3

2004-11-29 Alexandre Carmel-Veilleux <acv@acv.ca>
        * wifidog.conf: Fixed firewall rule bug.
        * src/fw_iptables.c: Unknown user default block rule not "REJECT"
          instead of "DROP"

2004-11-23 Alexandre Carmel-Veilleux <acv@acv.ca>
        * src/conf.c: Fixed a NULL pointer dereference in get_ruleset().

2004-11-22 Alexandre Carmel-Veilleux <acv@acv.ca>
        * libhttpd/api.c: Fix leak in HttpdEndRequest().
        * src/ping_thread.c: Fix auth_server IP change code with latest
          from previous branch.
        * src/conf.h: Same as above.
        * src/fw_iptables.c: Same as above.
        * src/conf.[ch]: Firewall rule set parsing code.
        * wifidog.conf: Default firewall rule set defined.
        * src/fw_iptables.[ch]: Firewall rule set enacting code.
        * configure.in: bumped version to 1.1.0-alpha2

2004-11-18 Benoit Grégoire  <bock@step.polymtl.ca>
        * src/ping_thread.c: Merge phil's bug fixes from stable branch
        * ipkg/rules:  Merge phil's bug fixes from stable branch
        * configure.in:  Set version to 1.1.0alpha
        
2004-11-18 Alexandre Carmel-Veilleux <acv@acv.ca>
        * src/fw_iptables.[ch]: Merged in Phil's patch.
        * src/*: Added ping_thread hooks to reset authserver table in the
          firewall if it notices the auth_servers changing IPs.

2004-11-17 Alexandre Carmel-Veilleux <acv@acv.ca>
        * libhttpd/*: libhttpd has been taken behind the shed and shot in
          the back of the head. The replacement separates the request struct
          from the server struct. It's thread safe if none of OUR threads
          write to server.
        * src/*: All the changes to handle the new libhttpd and also to
          move over to a worker thread system. http_callback_auth() no
          longer spawns a thread either.
        * *: this update preceded by a cvs tag PRE_NEW_LIBHTTPD.
        * *: You want to check the mailing list archive also.

2004-11-10 Alexandre Carmel-Veilleux <acv@acv.ca>
        * libhttpd/protocol.c: select() based timeout.

2004-10-31 Alexandre Carmel-Veilleux <acv@acv.ca>
        * configure.in: bumped version number to "1.0.2-pre1" since we
          already have ile sans fil hot spots advertising "1.0.1".

2004-10-30 Alexandre Carmel-Veilleux <acv@acv.ca>
        * src/ping_thread.c: asynch read(). fixed bug in byte counting.

2004-10-29 Philippe April <philippe@philippeapril.com>
        * ipkg/rules: added conffiles so it does not overwrite config files

2004-10-29 Alexandre Carmel-Veilleux <acv@acv.ca>
        * src/ping_thread.c: Much new debugging information
        * multiple files: Logging for all mutexes

2004-10-28 Philippe April <philippe@philippeapril.com>
        * ipkg/rules: building ipkg-tools before packaging

2004-10-28 Alexandre Carmel-Veilleux <acv@acv.ca>
        * multiple files: Implemented a FirewallRule config command, it
          doesn't actually do anything yet.
        * libhttpd: #if 0'd out lots of request parsing code.
        * libhttpd: changed URL parsing.

2004-10-27 Philippe April <philippe@philippeapril.com>
        * ipkg/rules: removed --build=mipsel from ./configure

2004-10-26 Philippe April <philippe@philippeapril.com>
        * ipkg/rules: sed -i is not standard, did a workaround.

        * wifidog.spec.in:  Rework spec file.  Now works and include the init script
        * ipkg/rules:  Deal with the incomplete init.d system of the OpenWrt.   Install scripts/init.d/wifidog as /usr/bin/wifidog-init, and call wifidog-init start from S65wifidog.

        * wifidog.conf:  Add more doc, and (most) of ISF's default config in comments.
        * Bump version in anticipation for release

2004-08-25 Alexandre Carmel-Veilleux <acv@acv.ca>
        * src/auth.c: Path as changed in 1.26 was preceded by a /, the path already contains a / so it would yield http://host//path/

        * Properly integrate libhttpd into the source tree ;)  Note that this will create a proper system wide shared library for libghttpd.  Still to be done:  1- Store Mina's patch somewhere,  in case we want to upgrade libhttpd.  2-Add configure option not to build httpd, and use an already installed one.

2004-04-18  Alexandre Carmel-Veilleux <acv@acv.ca>

2004-04-12  Alexandre Carmel-Veilleux <acv@acv.ca>
        * Changed child return value handling, again. Now it's actually
        using the real value instead of the flag.
        * The http.c authentication code now closes the http connection
        from the user.

2004-04-11  Alexandre Carmel-Veilleux <acv@acv.ca>

        * Very large modification. The entire architecture has been reworked
        so that authentications to the central server are performed in a
        fork()'d child process and the exit code from that child is then
        used to set the User Class of the connection.
        * The UserClasses (global definitions) and Rights (per connection)
        have been integrated.

2004-03-16  Mina Naguib <minaguib@users.sourceforge.net>
        * Changed HTTP server tasks to be handled by libhttpd - merged
        incorporate_libhttpd branch

2004-03-13  Philippe April <papril777@yahoo.com>
        * Modified the way firewall scripts are called so we can configure
        them in the config file (a bit more modular than it was)
        * Added simple linked list to keep track of clients and to
        keep a counter of the utilization and send it to the auth server
        * Fixed CRLF/formatting in phpauth/auth/index.php
        * Hacked phpauth/auth/index.php to handle very basic utilization tracking

        * Changed all perror()s into debug()s and added errno.h to common.h

2004-03-10  Philippe April <papril777@yahoo.com>
        * Small fix to firewall.c so we don't define variables after
        the function has started (so it builds on gcc-2.95)

2004-03-09  Philippe April <papril777@yahoo.com>
        * Major changes, not forking anymore for new connections, now using
        select() instead. It will allow us to efficiently use a linked list to track
        users and other things. It introduces some bugs and design issues but will
        be better in the end.

2004-03-09  Philippe April <papril777@yahoo.com>
        * Small fix in the default.php login page
        * exit() where the program was supposed to exit but wasn't when the
        firewall could not be setup

2004-03-09  Alexandre Carmel-Veilleux <acv@acv.ca>
        * Tiny change to increase cross-platform compatibility. It can now build on OS X and it comes close to building on my old BSD box.

2004-03-08  Benoit Grégoire  <bock@step.polymtl.ca>
        * Initial CVS import.  Integrate a standrad GNU build system and Doxygen to the build process.  Add Doxygen and CVS headers, .cvsignores, etc.  Note that the imported code is Philippe April (papril777 at yahoo.com)'s work.  Tell me if I forgot anything.  Please note that the paths in the src/fw* scripts are still hardcoded.  Don't forget to update the ChangeLog file every commit and add doxygen comments to your code.  Happy hacking.
