1999-11-17Added skeleton of command tree. Please inspect.Martin Mares
1999-08-03Basic support for IPv6. The system-dependent part doesn't work yet,Martin Mares
but the core routines are there and seem to be working. o lib/ipv6.[ch] written o Lexical analyser recognizes IPv6 addresses and when in IPv6 mode, treats pure IPv4 addresses as router IDs. o Router ID must be configured manually on IPv6 systems. o Added SCOPE_ORGANIZATION for org-scoped IPv6 multicasts. o Fixed few places where ipa_(hton|ntoh) was called as a function returning converted address.
1999-08-03Pruned the TODO list.Martin Mares
1999-08-03Kernel route syncer supports multiple tables.Martin Mares
The changes are just too extensive for lazy me to list them there, but see the comment at the top of sysdep/unix/krt.c. The code got a bit more ifdeffy than I'd like, though. Also fixed a bunch of FIXME's and added a couple of others. :)
1999-08-03Added missing structure declarations.Martin Mares
1999-08-03Changes to interface handling on traditional Unices:Martin Mares
o Aliases are interpreted as secondary addresses. o When the system doesn't supply interface indices, generate our ones.
1999-08-03Faster checksum function.Martin Mares
1999-08-03Added functions for parsing and formatting of dates.Martin Mares
1999-05-26Better date/time input methods need to be donePavel Machek
1999-05-21Added --with-sysinclude to allow explicitly setting where kernel includesMartin Mares
reside, so that you can easily switch between 2.0 and 2.2 ones. Check existence of <linux/rtnetlink.h> for linux-22 configs to make sure we're using the correct set of includes.
1999-05-14Added ip_skip_header() and modified OSPF to use it.Martin Mares
1999-05-07Netlink support for secondary interface addresses.Martin Mares
1999-05-06I rewrote the interface handling code, so that it supports multipleMartin Mares
addresses per interface (needed for example for IPv6 support). Visible changes: o struct iface now contains a list of all interface addresses (represented by struct ifa), iface->addr points to the primary address (if any). o Interface has IF_UP set iff it's up and it has a primary address. o IF_UP is now independent on IF_IGNORED (i.e., you need to test IF_IGNORED in the protocols; I've added this, but please check). o The if_notify_change hook has been simplified (only one interface pointer etc.). o Introduced a ifa_notify_change hook. (For now, only the Direct protocol does use it -- it's wise to just listen to device routes in all other protocols.) o Removed IF_CHANGE_FLAGS notifier flag (it was meaningless anyway). o Updated all the code except netlink (I'll look at it tomorrow) to match the new semantics (please look at your code to ensure I did it right). Things to fix: o Netlink. o Make krt-iface interpret "eth0:1"-type aliases as secondary addresses.
1999-04-27Recognize site scope for IPv4 addresses (prefixes reserved for privateMartin Mares
networks). Removed old #ifndef logic which was used to avoid IPv4/IPv6 clashes before conditionals in Modules lists were introduced.
1999-04-12Removed TOS support. This simplifies many things a lot.Martin Mares
1999-04-12Fixed a couple of bugs in handling of multicast sockets.Martin Mares
See comments in lib/socket.h for a detailed guide on how to use them.
1999-04-03Added new protocol hook for dumping of protocol-dependent routeMartin Mares
attributes. Please implement in all protocols.
1999-03-29Updated the TODO list.Martin Mares
1999-03-26Moved to a much more systematic way of configuring kernel protocols.Martin Mares
o Nothing is configured automatically. You _need_ to specify the kernel syncer in config file in order to get it started. o Syncing has been split to route syncer (protocol "Kernel") and interface syncer (protocol "Device"), device routes are generated by protocol "Direct" (now can exist in multiple instances, so that it will be possible to feed different device routes to different routing tables once multiple tables get supported). See doc/bird.conf.example for a living example of these shiny features.
1999-03-03Rewrote the kernel syncer. The old layering was horrible.Martin Mares
The new kernel syncer is cleanly split between generic UNIX module and OS dependent submodules: - krt.c (the generic part) - krt-iface (low-level functions for interface handling) - krt-scan (low-level functions for routing table scanning) - krt-set (low-level functions for setting of kernel routes) krt-set and krt-iface are common for all BSD-like Unices, krt-scan is heavily system dependent (most Unices require /dev/kmem parsing, Linux uses /proc), Netlink substitues all three modules. We expect each UNIX port supports kernel routing table scanning, kernel interface table scanning, kernel route manipulation and possibly also asynchronous event notifications (new route, interface state change; not implemented yet) and build the KRT protocol on the top of these primitive operations.
1999-03-02Netlink module supports interface scan on startup. Working on more.Martin Mares
1999-03-01Implemented netlink protocol parsing functions. More to come tomorrow.Martin Mares
1999-03-01Added skeletal version of Linux netlink interface. It doesn't work yet,Martin Mares
but the framework is there and I'll try finish it soon.
1999-03-01Pruned the TODO list.Martin Mares
1999-02-13Cleaned up TODO file.Martin Mares
That's all for today, midnight gets closer.
1999-02-13'#' comments in config files are equivalent to end of line, thereforeMartin Mares
also to implicit ';'.
1999-02-13Squashed one bug in timing of route scans.Martin Mares
1999-02-13config->router_id works again.Martin Mares
1999-02-11Real implementation of protocol state machines. Delayed startup/shutdownMartin Mares
should work now. Initial feeding of protocols by interfaces/routes is done from the event queue to prevent unwanted recursion.
1999-02-11Added simple event scheduling system to avoid recursive callingMartin Mares
of various callbacks. Events are just another resource type objects (thus automatically freed and unlinked when the protocol using them shuts down). Each event can be linked in at most one event list. For most purposes, just use the global event list handled by the following functions: ev_schedule Schedule event to be called at the next event scheduling point. If the event was already scheduled, it's just re-linked to the end of the list. ev_postpone Postpone an already scheduled event, so that it won't get called. Postponed events can be scheduled again by ev_schedule(). You can also create custom event lists to build your own synchronization primitives. Just use: ev_init_list to initialize an event list ev_enqueue to schedule event on specified event list ev_postpone works as well for custom lists ev_run_list to run all events on your custom list ev_run to run a specific event and dequeue it
1999-02-05Implemented new configuration/reconfiguration interface and defined protocolMartin Mares
state machines. Full explanation will follow soon.
1999-01-10New makefiles. Includes support for out-of-source-tree builds.Martin Mares
1998-12-20Finer grained logging levels:Martin Mares
#define L_DEBUG "\001" /* Debugging messages */ #define L_INFO "\002" /* Informational messages */ #define L_WARN "\003" /* Warnings */ #define L_ERR "\004" /* Errors */ #define L_AUTH "\005" /* Authorization failed etc. */ #define L_FATAL "\006" /* Fatal errors */ #define L_TRACE "\002" /* Protocol tracing */ #define L_INFO "\003" /* Informational messages */ #define L_REMOTE "\004" /* Remote protocol errors */ #define L_WARN "\004" /* Local warnings */ #define L_ERR "\005" /* Local errors */ #define L_AUTH "\006" /* Authorization failed etc. */ #define L_FATAL "\007" /* Fatal errors */ #define L_BUG "\010" /* BIRD bugs */ Introduced bug() which is like die(), but with level L_BUG. Protocols should _never_ call die() as it should be used only during initialization and on irrecoverable catastrophic events like out of memory. Also introduced ASSERT() which behaves like normal assert(), but it calls bug() when assertion fails. When !defined(DEBUGGING), it gets ignored.
1998-12-08Hopefully finished kernel syncer (krt) rewrite:Martin Mares
o Interface syncing is now a part of krt and it can have configurable parameters. Actually, the only one is scan rate now :) o Kernel routing table syncing is now synchronized with interface syncing (we need the most recent version of the interface list to prevent lots of routes to non-existent destinations from appearing). Instead of its own timer, we just check if it's route scan time after each iface list scan. o Syncing of device routes implemented. o CONFIG_AUTO_ROUTES should control syncing of automatic device routes. o Rewrote krt_remove_route() to really remove routes :) o Better diagnostics. o Fixed a couple of bugs.
1998-12-07All static routes except for device ones should work and appear/disappearMartin Mares
when their destination comes on/off link. Deserves better testing :) See example in bird.conf.
1998-12-06Added skeleton of static route protocol.Martin Mares
1998-11-29Added configuration of the device internal protocol. This is primarilyMartin Mares
intended to serve as an example of interface pattern list use. As a side effect, you can disable generating of device routes by disabling this protocol.
1998-11-29`wc -l TODO` decreased.Martin Mares
1998-11-27Trivial 15-line bison excercise: Implemented expressions includingMartin Mares
user-defined numeric symbols. Whenever possible, use `expr' instead of `NUM' to get full express ion power :-)
1998-10-19Updated TODO.Martin Mares
1998-10-19We parse /proc/net/route and flag RT entries according to it. More to comeMartin Mares
today in the morning...
1998-10-18* Please distinguish between DGB() and debug().Martin Mares
1998-10-13o There are cases when SIOCGIFINDEX is defined, but it doesn't work. WhenMartin Mares
this happens, don't reject the whole interface, just mark it as index 0. o Removed Pavel's comment about EFAULT and SIGSEGV. EFAULT is a valid return code for cases where the buffer is too small. o Commented out the smart interface list size logic temporarily as it seems Linux 2.0 SIOCGIFCONF doesn't react to ifc_req==NULL sanely. Replaced it by exponential stepping.
1998-06-17Added local version of sprintf (bsprintf and bvsprintf) offering few newMartin Mares
format strings: %I IP address %#I IP address in hexadecimal %1I IP address padded to full length %m strerror(errno)
1998-06-01- Rewrote whole interface logic. Removed support for multiple addresses perMartin Mares
interface since it makes much trouble everywhere. Instead, we understand secondary addresses as subinterfaces. - In case interface addresses or basic flags change, we simply convert it to a down/up sequence. - Implemented the universal neighbour cache. (Just forget what did previous includes say of neighbour caching, this one is brand new.)
1998-05-26DBG now calls debug() instead of sending it to log().Martin Mares
1998-05-03BIRD library: The story continues.Martin Mares
Complete resource manages and IP address handling.
1998-04-22First look at data structures. More to come tomorrow...Martin Mares
