2011-10-17IPv6 transport class suppportStephen Hemminger
IPv6 supports the same concept of differentiated service for routing protocols as IPv4, but like too many things, the standards committee decided that having two names for the same thing wasn't good enough and introduced a third more generic term transport class. The socket option to set transport class works the same as IPv4, but the arguments are different. * lib/sockopt.[ch] * setsockopt_ipv6_tclass(): new function * bgpd/bgp_network.c * bgp_connect(): set socket option * bgp_listener(): set socket option * ospf6d/ospf6_network.c * ospf6_set_transport_class(): new function * ospf6_serv_sock(): set socket option * ripngd/ripngd.c * ripng_make_socket(): set socket option
2011-09-27lib: use "protocol-independed API" from RFC3678, if that is availableDmitrij Tejblum
(This commit is based on the patch from BZ#420, and should fix that bug.) * configure.ac: detect availability of that API * sockopt.c (setsockopt_ipv4_multicast): use it for join/leave IPv4 multicast groups
2011-09-27lib: futher simplification of setsockopt_ipv4_multicast()Dmitrij Tejblum
* sockopt.c (setsockopt_ipv4_multicast): check for wrong optname with assert(), rather than return an error.
2011-09-27lib: fix omission in the previous commit to lib/sockopt.cDmitrij Tejblum
* sockopt.c (setsockopt_ipv4_multicast_if): fix missed line in the previous commit.
2011-09-27lib: simplify interface of setsockopt_multicast_ipv4().Dmitrij Tejblum
* sockopt.[ch] (setsockopt_ipv4_multicast): ifindex is now mandatory (all non-ancient OSes can use it anyway), and if_addr parameter (the address of the interface) is now gone. (setsockopt_ipv4_multicast_if): IP_MULTICAST_IF processing moved to this new function * ospf_network.c (ospf_if_add_allspfrouters, ospf_if_drop_allspfrouters, ospf_if_add_alldrouters, ospf_if_drop_alldrouters, ospf_if_ipmulticast), rip_interface.c (ipv4_multicast_join, ipv4_multicast_leave, rip_interface_new): adapt to the new interface
2011-09-27lib: remove unused variableDenis Ovsienko
* sockopt.c (getsockopt_ifindex): "ifindex" was never used
2009-06-23Fixes to RFC2385/MD5 BGPChris Caputo
* bgpd/bgp_network.c: Fix MD5 listen in IPv4 version of bgp_socket() by adding listen socket to listen_sockets list so that MD5 passwords can get set. * lib/sockopt.c: (sockopt_tcp_signature) Fix bogus "% Error while applying TCP-Sig to session(s)" / "can't set TCP_MD5SIG option" startup error messages by not returning error when there isn't one.
2009-06-18[lib] sockopt_tcp_signature: sin6 requires HAVE_IPV6Stephen Hemminger
An external user was building on system without IPv6 and it wouldn't work.
2009-06-12[bgpd] Add support for the old Linux 2.4, TCP_MD5_AUTH RFC2385 patchPaul Jakma
* 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.
2008-08-22[lib] Fix mistake in tcp-md5sig commit which broke compile on BSDPaul Jakma
2008-08-15 Paul Jakma <paul.jakma@sun.com> * lib/sockopt.c: (sockopt_tcp_signature) ifdef'ing hid variable declaration for HAVE_DECL_TCP_MD5SIG && !GNU_LINUX, breaking compile - fix.
2008-08-22[lib] mes_lookup string lookup table argument should be marked constStephen Hemminger
2008-08-14 Stephen Hemminger <stephen.hemminger@vyatta.com> * lib/log.{c,h}: struct message argument should point to const * */*.c: adjust to suit, Signed-off-by: Paul Jakma <paul@quagga.net>
2008-07-21[bgpd] TCP-MD5: password vty configuration and initial Linux supportPaul Jakma
2008-07-21 Paul Jakma <paul.jakma@sun.com> * bgp_packet.c: (bgp_open_receive) fix warning in a zlog call * bgp_vty.c: (bgp_vty_return) add return code * bgpd.c: (bgp_master_init) setup the socket list. * bgp_network.c: Remove the dual IPv4/6 socket thing for now, which was implemented by Michael, until such time as its clear its required for Linux (see sockopt comments). 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. Warfield <mhw@wittsend.com> YOSHIFUJI Hideaki <yoshfuji@linux-ipv6.org> Tomohiko Kusuda <kusuda@inetcore.com> Leigh Brown <leigh@solinno.co.uk> * bgp_network.c: (bgp_md5_set_one) shim between libzebra tcp-md5 sockopt and bgpd. (bgp_md5_set_socket) Helper for bgp_connect (bgp_md5_set) setup TCP-MD5SIG for the given peer. (bgp_connect) call out to bgp_md5_set_socket for the outgoing connect socket. (bgp_socket) save references to the listen sockets, needed if TCP-MD5SIG is applied later or changed. * bgp_vty.c: (*neighbor_password_cmd) New 'neighbor ... password' commands. * bgpd.c: (peer_{new,delete) manage TCP-MD5 password (peer_group2peer_config_copy) inherit TCP-MD5 password (peer_password_{un,}set) orchestrate the whole add/remove of TCP-MD5 passwords: applying checks, stopping peers, and trying to return errors to UI, etc. (bgp_config_write_peer) save password. Fix missing newline in writeout of neighbor ... port. 2008-07-21 Paul Jakma <paul.jakma@sun.com> * sockunion.c: ifdef out various places that converted v4mapped sockets to pure v4. Doesn't seem necessary at all, presumably a workaround for now historical inet_ntop bugs (?) 2008-07-21 Michael H. Warfield <mhw@wittsend.com> YOSHIFUJI Hideaki <yoshfuji@linux-ipv6.org> * sockopt.{c,h}: (sockopt_tcp_signature) Add TCP-MD5SIG support.

2007-07-06[lib] Add comments regarding setsockopt_multicast_ipv4 arguments.Andrew J. Schorr
2007-07-06 Andrew J. Schorr <ajschorr@alumni.princeton.edu> * sockopt.{c,h}: (setsockopt_multicast_ipv4) Add some comments about the arguments.
2005-10-212005-10-20 Andrew J. Schorr <ajschorr@alumni.princeton.edu>ajs
* sockopt.c: (setsockopt_multicast_ipv4) If IP_ADD_MEMBERSHIP fails with errno equal to EADDRINUSE, then issue an info message and try IP_DROP_MEMBERSHIP followed by IP_ADD_MEMBERSHIP.
2005-05-072005-05-07 Yar Tikhiy <yar@comp.chem.msu.su>paul
* configure.ac: Check for OSes which support passing ifindex in struct ip_mreq. * lib/sockopt.c: Add support for BSD style ifindex in ip_mreq. * ospfd/ospf_network.c: Log ifindex on multicast membership leave/join events.
2005-01-042005-01-04 Andrew J. Schorr <ajschorr@alumni.princeton.edu>ajs
* configure.ac: Added test for broken CMSG_FIRSTHDR macro (relevant for Solaris 8 and unpatched Solaris 9, don't know whether other platforms are affected). * zebra.h: Define ZCMSG_FIRSTHDR appropriately based on whether config.h indicates HAVE_BROKEN_CMSG_FIRSTHDR (as determined by the configure test program). * sockopt.c: (getsockopt_cmsg_data) Use ZCMSG_FIRSTHDR instead of CMSG_FIRSTHDR. * rtadv.c: (rtadv_recv_packet,rtadv_send_packet) Use ZCMSG_FIRSTHDR instead of CMSG_FIRSTHDR. * ripd.c: (rip_recvmsg) Use ZCMSG_FIRSTHDR instead of CMSG_FIRSTHDR. * ripngd.c: (ripng_recv_packet) Use ZCMSG_FIRSTHDR instead of CMSG_FIRSTHDR.

* 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.
2004-12-292004-12-29 Greg Troxel <gdt@poblano.ir.bbn.com>gdt
* sockopt.c (getsockopt_ipv4_ifindex): Return 0 when passed a NULL cmsghdr pointer. I believe this will avoid ospfd crashing on Solaris 8, which seems to define IP_RECVIF but not actually implement it.
2004-12-282004-12-28 Andrew J. Schorr <ajschorr@alumni.princeton.edu>ajs
* sockopt.c: (setsockopt_ipv4_ifindex) Improve error message. When neither IP_PKTINFO nor IP_RECVIF is defined, make return value deterministic (-1).
2004-11-202004-11-19 Andrew J. Schorr <ajschorr@alumni.princeton.edu>ajs
* global: Replace strerror with safe_strerror. And vtysh/vtysh.c needs to include "log.h" to pick up the declaration.
2004-11-19Fix previous change to use new function safe_strerror instead of strerror.ajs
2004-11-192004-11-19 Andrew J. Schorr <ajschorr@alumni.princeton.edu>ajs
* sockopt.c: (setsockopt_so_recvbuf) Stop error message from being printed every time.
2004-11-012004-11-01 Paul Jakma <paul@dishone.st>paul
* sockopt.c: (setsockopt_pktinfo) remove, its unused.
2004-10-222004-10-22 Paul Jakma <paul@dishone.st>paul
* sockopt.c: (setsockopt_pktinfo) unexported * sockopt.h: Cleanup SOCKOPT_CMSG defines a bit. Add a throwaway define for SOPT_SIZE_CMSG_IFINDEX_IPV4 for systems which have neither IP_RECVIF nor IP_PKTINFO (eg openbsd).
2004-10-222004-10-13 Paul Jakma <paul@dishone.st>paul
* sockopt.c: (getsockopt_ipv4_ifindex) no ifindex should be 0, not -1.
