e858dce757 Moved the thread starting code to IO loop code 2022-07-28 19:49:03 +02:00

94eb0858c2 Converting the former BFD loop to a universal IO loop and protocol loop.
There is a simple universal IO loop, taking care of events, timers and
sockets. Primarily, one instance of a protocol should use exactly one IO
loop to do all its work, as is now done in BFD.

Contrary to previous versions, the loop is now launched and cleaned by
the nest/proto.c code, allowing for a protocol to just request its own
loop by setting the loop's lock order in config higher than the_bird.

It is not supported nor checked if any protocol changed the requested
lock order in reconfigure. No protocol should do it at all.

a4451535c6 Unified time for whole BIRD
In previous versions, every thread used its own time structures,
effectively leading to different time in every thread and strange
logging messages.

The time processing code now uses global atomic variables to keep
current time available for fast concurrent reading and safe updates.

fd9f0c0640 Configuration strings are constant.
This is merely a const propagation. There was no problem in there.

863ecfc785 The MRT protocol
The new MRT protocol is responsible for periodic RIB table dumps in the
MRT format (RFC 6396). Also the existing code for BGP4MP MRT dumps is
refactored and splitted between BGP to MRT protocols, will be more
integrated into MRT in the future.

Example:

protocol mrt {
        table "*";
        filename "%N_%F_%T.mrt";
        period 60;
}

It is partially based on the old MRT code from Pavel Tvrdik.

f047271cb9 Timers: Parse and format functions for microsecond times
Date/time output (e.g. in logs, show commands) can use %f to specify
subsecond time. By default, millisecond precision is used in output.

025525266f Timers: Replace old timers with microsecond timers
The old timer interface is still kept, but implemented by new timers. The
plan is to switch from the old inteface to the new interface, then clean
it up.

25697773b5 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.

1feea03e74 Changed #include <x/y> to #include "x/y" for our local includes, so that
gcc -MM can be used to separate them from the system ones.

Added automatic generation of dependencies.
