* Don't return "Not Supported" when setting NULL MD5 passwordChris Hall2010-04-281-2/+7
| | | | | | | | | | | | | | | | | If TCP MD5 signature is not supported, sockopt_tcp_signature() returns ENOSYS. This change means that if the given password is NULL or an empty string, then returns OK, even when TCP MD5 signature is not supported. If the password is being cleared, it doesn't matter that it could never have bee set in the first place ! This means that unless a password is required, it is safe to call sockopt_tcp_signature() whether the facility is supported or not. Which further means that only this function needs to worry about the circumstances under which it is supported !

* New functions for error numbers and addresses in messages.Chris Hall2010-04-081-16/+17
| | | | | | | | Implemented less onerous ways of including descriptions of errors and IP addresses in logging and other messages. Implemented mapping of error numbers to error names, which is generally more meaningful.
* First beta releaseChris Hall2010-04-061-117/+200
| | | | | | | Various bug fixes and improvements. Running with a fair amount of debug/assert code, which must be removed at some date.
* Getting BGP Engine to start and removing warnings.Chris Hall2010-01-241-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Finish the wiring required to get bgp_msg_read to process OPEN messages into the connection's open_state, and be able to check for correct peer AS, etc. Removed bugs preventing messages from being written. Added BGP Id check to collision detection logic. Removed as many warnings from comilation as possible. Replaced horrible FIFO kludge in the process. (Introduced the even more horrible miyagi kludge.) modified: bgpd/bgp_advertise.c modified: bgpd/bgp_advertise.h modified: bgpd/bgp_connection.c modified: bgpd/bgp_connection.h modified: bgpd/bgp_debug.c modified: bgpd/bgp_fsm.c modified: bgpd/bgp_msg_read.c modified: bgpd/bgp_msg_write.c modified: bgpd/bgp_network.c modified: bgpd/bgp_nexthop.c modified: bgpd/bgp_notification.c modified: bgpd/bgp_open.c modified: bgpd/bgp_packet.c modified: bgpd/bgp_session.c modified: bgpd/bgp_session.h modified: bgpd/bgpd.c modified: lib/Makefile.am modified: lib/distribute.c modified: lib/if_rmap.c new file: lib/miyagi.h modified: lib/prefix.h modified: lib/sockopt.c modified: lib/stream.c modified: lib/thread.c modified: lib/vty.c modified: lib/zebra.h modified: tests/bgp_capability_test.c modified: tests/bgp_mp_attr_test.c modified: tests/ecommunity_test.c modified: tests/heavy-thread.c modified: tests/heavy-wq.c modified: tests/heavy.c modified: tests/main.c modified: tests/test-checksum.c modified: tests/test-sig.c modified: watchquagga/watchquagga.c modified: zebra/if_netlink.c modified: zebra/ioctl.c modified: zebra/rt_netlink.c modified: zebra/rtread_netlink.c

* [bgpd] Add support for the old Linux 2.4, TCP_MD5_AUTH RFC2385 patchPaul Jakma2009-06-121-2/+25
| | | | | | | | | * configure.ac: Add a --enable-linux24-tcp-md5 argument, to compile in support for the old TCP-MD5 patch for Linux 2.4 systems. This overrides auto-detection of TCP-MD5 supported by the target system. * lib/sockopt.c: (sockopt_tcp_signature) add in a variant for the old Linux 2.4, TCP_MD5_AUTH variant of TCP-MD5 support, conditional on the previous configure arg.

IPv6 support, including IPv4 sessions on AF_INET6 sockets, therefore is broken, and the '-l 0.0.0.0' arguments would need to be given to bgpd to make things work here. 2008-07-21 Michael H.

| | | | | | | | | * sockopt.c (getsockopt_ipv4_ifindex): Document calling convention. Beef up comments. Handle the case where the cmsghdr has a zero controllen, or more specifically when the wanted option is not present. This is needed for Solaris 8, and in general for any platform for which configure finds a method and it can fail. Mark some changes with XXX to be cleaned up post 0.98.
