Converted shutdown to a kind of reconfiguration, it's no more handledas a exception in protocol state machines. Introduced a `shutdown'CLI command. Killed few reconfiguration bugs.
First attempt on dynamic reconfiguration. There are still lots of bugsand problems to solve, but the hardest part works.
Added universal locking mechanism which will solve problemswith protocols wanting to use the same port on the same interfaceduring reconfiguration time.
How to use locks: In the if_notify hook, just order locks for theinterfaces you want to work with and do the real socket opening after the...
- Path to control socket is selectable via command-line option.- die() when control socket open failed.
Logging is now configurable. You can define multiple log outputs (to bothfiles and syslog) and assign lists of message categories to each of them.
The CLI I/O functions work as desired.
First steps of the Command Line Interface: I/O routines.
Believe it or not, printf()'s does not work too much without this one.
Clarify resource dumps and include them in the main debugging dump.
Moved to a much more systematic way of configuring kernel protocols.
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...
Use dmalloc instead of EFence when available (dmalloc has lot of improvementsover EFence and also hopefully smaller memory overhead, but sadly it's non-freefor commercial use).
If the DMALLOC_OPTIONS environment variable is not set, switch on `reasonable'...
Rewrote the kernel syncer. The old layering was horrible.
The new kernel syncer is cleanly split between generic UNIX moduleand 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)...
Perform gracious shutdown upon receipt of SIGTERM. Finally we cantest the whole protocol shutdown code... :)
Synchronize signals to the main select/event/timer loop.
Parse command line options.
Run the event queue before writing SIGUSR dumps.
Implemented new configuration/reconfiguration interface and defined protocolstate machines. Full explanation will follow soon.
filters_init() renamed to filters_postconfig().
Filters, second try. This time they have their own directory.
Properly initialize filters. Also bumped version to 0.0.0 as itactually does something.
die() -> bug() where appropriate.
Kernel syncer is now configurable. It will probably need some moreoptions, but at least basic tuning is possible now.
First attempt at protocol configuration (now done only for RIP).
Compile and use the new configuration code by default.
Generate router_id automatically if possible (standard "smallest of localregular interface addresses" rule).
Protocols should NOT rely on router_id existence -- when router ID is notavailable, the router_id variable is set to zero and protocols requiring...
Since almost every UNIX system requires different techniques for readingthe kernel routing table as opposed to modifying it which is approximatelythe same on non-netlink systems, I've split the kernel routing tableroutines to read and write parts. To be implemented later ;-)
Split protocol init to building of protocol list and real protocol init.Added kernel route table syncer skeleton.
Solve chicken-and-egg problems with protocol startup. We now queue all inactiveprotocols 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.
Moved scanning of interfaces, so that they get initialized after allrouting protocol instances.
Making SIGUSR1 dump also all protocols.
Killed socket debug code. Initialize config pool and protocols.More to come later...
Synced to new interface code.
Implemented scanning of network interfaces. Mostly very ugly code due toterrible kernel interface (SIOGIFCONF and friends).
Added UNIX implementation of both timers and sockets. Timers should work,sockets were tested only in TCP mode. main.c now contains some testcases for socket code.
Added routing table and routing attribute code.
The library is now glued together from generic and OS-dependent partsby the `mergedirs' script. Few more IP address manipulation functionsand some fixes.
