Internet on FIRE

unsigned [int] -> uint

IPv4/IPv6 integrated socket code.

Workaround thread-unsafeness of cli_echo().

Flag -f "run in foreground" added as requested by a package maintainter.

Implements PID file support.

Thanks to Thierry Fournier for the original patch.

Implements undo command and optional timeout for configuration

Several new configure command variants:

configure undo - undo last reconfiguration
configure timeout - configure with scheduled undo if not confirmed in timeout
configure confirm - confirm last configuration...

Implements build options to specify socket dir and suffix.

Adds krt_source route attribute.

Thanks Jeremie Dimino for the original patch.

Route Origin Authorization basics.

- ROA tables, which are used as a basic part for RPKI.
 - Commands for examining and modifying ROA tables.
 - Filter operators based on ROA tables consistent with RFC 6483.

Configuration can include other files.

Update and document the privilege restriction.

Use constants from /etc/iproute2/rt_* files.

Adds check for no protocol and some minor CLI fixes.

- Adds check to deny config file with no specified protocol to prevent
loading of empty config file.
- Moves CLI init before config parse to receive immediate error message
when cannot open control socket....

Adds some log messages related to configure.

Also fixes a bug in the previous patch.

Implement option to exit after config file parsing.

Fixes BIRD socket unlink.

Adds support for soft reconfiguration.

Detach from the TTY properly.

Marked unused parameters in sysdep code as such.

Move CLI socket to the newly created CLI's pool.

(thanks to Andreas for the original idea)

Fix handling on full pipe to client in bird. Prevent packet overflows
for even only medium sized route table output. Fix a strange garbled
output problem in the client. The latter seems to be caused by some
library doing tcflush while there is still command output pending. So...

If compiled with --enable-debug, don't even try to log to syslog unless
the user forces it in the config file.

Tracing of CLI connections/commands can be now controlled
by `debug commands <level>' in the configuration. Level 0 means
no tracing, 1 means connections only, 2 includes all commands.

Fixed type in daemonization code.

#ifdef out lots of debugging information.

The long resource/routing table dump printed upon startup is gone now
and if you wish to see it, just send bird SIGUSR1 or use the `debug'
commands.

Changed handling of incoming connections, so that we can send data
from the send hook without worrying about existence of socket buffers.

Also, don't forget to copy peer addresses.

Include "lib/string.h" instead of <string.h>. It should give us bzero()
and other non-portable functions on all systems.

Fixed a bunch of FIXME's by removing them :)

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.

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...

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.

First steps of the Command Line Interface: I/O routines.

Clarify resource dumps and include them in the main debugging dump.

Use dmalloc instead of EFence when available (dmalloc has lot of improvements
over EFence and also hopefully smaller memory overhead, but sadly it's non-free
for commercial use).

If the DMALLOC_OPTIONS environment variable is not set, switch on `reasonable'...

Perform gracious shutdown upon receipt of SIGTERM. Finally we can
test the whole protocol shutdown code... :)

Run the event queue before writing SIGUSR dumps.

filters_init() renamed to filters_postconfig().

Properly initialize filters. Also bumped version to 0.0.0 as it
actually does something.

Kernel syncer is now configurable. It will probably need some more
options, but at least basic tuning is possible now.

Compile and use the new configuration code by default.

Since almost every UNIX system requires different techniques for reading
the kernel routing table as opposed to modifying it which is approximately
the same on non-netlink systems, I've split the kernel routing table
routines to read and write parts. To be implemented later ;-)

Solve chicken-and-egg problems with protocol startup. We now queue all inactive
protocols and don't send route/interface updates to them and when they come up,
we resend the whole route/interface tables privately.

Removed the "scan interface list after protocol start" work-around.

Making SIGUSR1 dump also all protocols.

Synced to new interface code.

Added UNIX implementation of both timers and sockets. Timers should work,
sockets were tested only in TCP mode. main.c now contains some test
cases for socket code.

The library is now glued together from generic and OS-dependent parts
by the `mergedirs' script. Few more IP address manipulation functions
and some fixes.
