Martin Mares 9fac310d1a Put client on a stony ground. The whole client is going to be system-specific
(the current version UNIX-specific) anyway, so it's useless to try splitting it
to sysdep and generic part. Instead of this, configure script decides (based on
system type and user's wish) what (if any) client should be built and what
autoconfiguration it requires. Also, the client provides its own die/bug/...
functions.

Martin Mares 3ea1ba632b Killed protocol->priority. Protocol startup should be clean and hack-free now.
It seems everything still works (except for disable/enable/restart which hangs
sometimes, but it's another story).
2000-01-18 11:01:03 +00:00
Martin Mares aa8761de94 Kernel route syncer now supports dynamic reconfiguration. Also it doesn't
depend on the startup counter hack now and uses a zero-time timer instead
to make itself scheduled after normal protocol startup.

Martin Mares d272fe22dd Separated `official protocol names' used in status dumps from name templates
used for automatic generation of instance names.

	protocol->name is the official name
	protocol->template is the name template (usually "name%d"),
		should be all lowercase.

Updated all protocols to define the templates, checked that their configuration
grammar includes proto_name which generates the name and interns it in the
symbol table.

Martin Mares f7fcb75252 Reconfiguration for device protocol. 2000-01-17 11:17:33 +00:00
Martin Mares 99278e1042 Wording changes. 2000-01-16 23:36:19 +00:00
Martin Mares bf8558bc9c Converted shutdown to a kind of reconfiguration, it's no more handled
as a exception in protocol state machines. Introduced a `shutdown'
CLI command. Killed few reconfiguration bugs.
2000-01-16 17:40:26 +00:00
Martin Mares 50fe90edf3 First attempt on dynamic reconfiguration. There are still lots of bugs
and problems to solve, but the hardest part works.

Martin Mares 476e108425 Minor cleanups. 1999-12-16 13:51:43 +00:00
Martin Mares e693ddff87 Handle cases when SIOCGIFINDEX is defined, but doesn't work (new glibc
with 2.0 kernels).
1999-12-16 13:23:32 +00:00
Martin Mares a2867cd957 Better order of includes.
set_inaddr() moved to sysio.h.
1999-12-16 13:14:02 +00:00
Martin Mares 67ece6df42 Tried to clean up multicast handling. Now we don't try to guess
multicast abilities depending on definedness of symbols and use hard-wired
system-dependent configuration defines instead.

Please test whereever you can.
1999-12-16 13:06:13 +00:00
Martin Mares f545d38707 Added universal locking mechanism which will solve problems
with protocols wanting to use the same port on the same interface
during reconfiguration time.

How to use locks: In the if_notify hook, just order locks for the
interfaces you want to work with and do the real socket opening after the
lock hook function gets called. When you stop using the socket, close
it and rfree() the lock.

Please update your protocols to use the new locking mechanism.

Martin Mares 30bc402ebb Temporary work-arounds for multicast problems. Needs further investigation. 1999-12-08 15:12:54 +00:00
Martin Mares 0da472d7e8 Except for special protocols (nowadays only the kernel syncer), don't
export host and link scope routes.
1999-12-08 14:16:13 +00:00
Martin Mares dc82daaa9b - Path to control socket is selectable via command-line option.
- die() when control socket open failed.
1999-12-08 13:20:19 +00:00
Martin Mares f78056fb2c Allow logging to stderr as well. 1999-12-06 13:51:04 +00:00
Martin Mares a0c37b45e5 Logging is now configurable. You can define multiple log outputs (to both
files and syslog) and assign lists of message categories to each of them.
1999-12-06 13:45:56 +00:00
Martin Mares a9c986f981 Added tracked_fopen() which is a fopen registered in resource database.
Will be used for log files.
1999-12-06 13:43:47 +00:00
Martin Mares 34350a5270 Implemented echoing of log messages to CLI connections. Just try `echo all'. 1999-12-06 12:34:45 +00:00
Martin Mares afa8937ac8 Added tm_format_reltime() for formatting of relative time quantities. 1999-12-01 11:59:00 +00:00
Martin Mares 487d1afa52 Moved TIME_INFINITY to timer.h, so that it's publicly available. 1999-11-30 14:01:39 +00:00
Martin Mares 30770df2ab If the main event queue is not empty, call select() with zero timeout, so
that the events are ran again after the FD's are checked. This allows us
to schedule I/O checks between processing of user commands.
1999-11-17 12:04:24 +00:00
Martin Mares b9672a845f The CLI I/O functions work as desired. 1999-10-31 15:43:44 +00:00
Martin Mares 7d3aab1c16 First steps of the Command Line Interface: I/O routines. 1999-10-29 12:10:10 +00:00
Martin Mares b93abffae4 Implemented unix-domain sockets. 1999-10-29 12:09:29 +00:00
Martin Mares ed6081502a Added skeleton of the client. Does nothing, but at least compiles. 1999-10-29 09:44:44 +00:00
Martin Mares f782b72c53 Failure to set socket TOS is not a fatal error. 1999-10-02 11:06:44 +00:00
Martin Mares f651941402 Added a function for generating 32-bit random numbers. 1999-08-17 20:47:40 +00:00
Martin Mares 4532a89e31 Taught Netlink how to behave in IPv6 world. 1999-08-03 19:37:37 +00:00
Martin Mares 4f22c98185 Support for IPv6 sockets. How nice one doesn't have to ifdef around
ten years of API evolution :-)
1999-08-03 19:36:51 +00:00
Martin Mares dce267832a Basic support for IPv6. The system-dependent part doesn't work yet,
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.
1999-08-03 19:36:06 +00:00
Martin Mares 7de45ba4a0 Kernel route syncer supports multiple tables.
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. :)
1999-08-03 19:33:22 +00:00
Martin Mares 9273035403 Changes to interface handling on traditional Unices:
o  Aliases are interpreted as secondary addresses.
  o  When the system doesn't supply interface indices, generate
     our ones.
1999-08-03 19:30:20 +00:00
Martin Mares 913f7dc9f2 Added functions for parsing and formatting of dates. 1999-08-03 19:29:27 +00:00
Martin Mares bd7f1081f2 Grrr, the "obvious fix" to multicasting code from yesterday was
fundamentally wrong. Reversed.
1999-06-01 15:31:43 +00:00
Martin Mares c7208da0b7 Fix potential multicasting bug. 1999-05-31 20:28:46 +00:00
Martin Mares bb027be1e2 Added extra argument to rt_update hook which contains a pointer to the
temporary attribute list.
1999-05-31 18:55:35 +00:00
Martin Mares 1c3c9dceb3 Removed one unused structure field. 1999-05-21 14:29:23 +00:00
Martin Mares 4f1a6d27b9 Kill remaining master_table relics in KRT code.
Make all protocols pass routing table to rte_update and rte_discard.
1999-05-17 20:16:53 +00:00
Martin Mares 9a158361da I rewrote the interface handling code, so that it supports multiple
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.
1999-05-06 21:38:11 +00:00
Martin Mares 4c5e5e3a1c Multicasts once again: When using SO_BINDTODEVICE, don't specify IP address
of the interface.
1999-04-14 12:29:47 +00:00
Martin Mares 1b50a1e4be Next attempt to get SO_BINDTODEVICE work :) 1999-04-14 11:39:07 +00:00
Martin Mares 36154beb70 Use SO_BINDTODEVICE if we're using old multicast API (i.e., struct ip_mreq
and not ip_mreqn). This should get multicasts on unnumbered PtP links work.
1999-04-14 11:21:02 +00:00
Martin Mares 01bd7759b2 Ignore alias interfaces (some day, we will treat them as pure secondary
interface addresses).
1999-04-12 18:07:05 +00:00
Martin Mares 08e2d6259a Removed TOS support. This simplifies many things a lot. 1999-04-12 18:01:07 +00:00
Martin Mares 61fb537c62 Use struct ip_mreqn' instead of struct ip_mreq' for multicast
operations on 2.1/2.2 kernels. This allows passing of real interface
indexes instead of referencing interfaces by their IP addresses which
fails badly in presence of unnumbered interfaces.

Unfortunately, this structure is not visible with glibc 2.0 as it provides
its own networking headers :-(  Both libc5 and glibc 2.1 should be OK.
1999-04-12 15:27:56 +00:00
Martin Mares 5a99ade413 Fixed a couple of bugs in handling of multicast sockets.
See comments in lib/socket.h for a detailed guide on how to use them.
1999-04-12 14:57:46 +00:00
Martin Mares 49ed70b48e Portability fixes. 1999-04-07 14:25:56 +00:00
Martin Mares c10421d3d4 More changes to the kernel syncer.
o  Now compatible with filtering.
o  Learning of kernel routes supported only on CONFIG_SELF_CONSCIOUS
   systems (on the others it's impossible to get it semantically correct).
o  Learning now stores all of its routes in a separate fib and selects
   the ones the kernel really uses for forwarding packets.
o  Better treatment of CONFIG_AUTO_ROUTES ports.
o  Lots of internal changes.
