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
|

* 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

* 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.

* 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 (?)

YOSHIFUJI Hideaki <yoshfuji@linux-ipv6.org>
* sockopt.{c,h}: (sockopt_tcp_signature) Add TCP-MD5SIG support.

* sockopt.{c,h}: (setsockopt_multicast_ipv4) Add some comments about
the arguments.
|
|
* (general) extern and static'ification of functions in code and
header.
Cleanup any definitions with unspecified arguments.
Add casts for callback assignments where the callback is defined,
typically, as passing void *, but the function being assigned has
some other pointer type defined as its argument, as gcc complains
about casts from void * to X* via function arguments.
Fix some old K&R style function argument definitions.
Add noreturn gcc attribute to some functions, as appropriate.
Add unused gcc attribute to some functions (eg ones meant to help
while debugging)
Add guard defines to headers which were missing them.
* command.c: (install_node) add const qualifier, still doesnt shut
up the warning though, because of the double pointer.
(cmp_node) ditto
* keychain.c: (key_str2time) Add GET_LONG_RANGE() macro, derived
fromn vty.h ones to fix some of the (long) < 0 warnings.
* thread.c: (various) use thread_empty
(cpu_record_hash_key) should cast to uintptr_t, a stdint.h type
* vty.h: Add VTY_GET_IPV4_ADDRESS and VTY_GET_IPV4_PREFIX so they
removed from ospfd/ospf_vty.h
* zebra.h: Move definition of ZEBRA_PORT to here, to remove
dependence of lib on zebra/zserv.h

in lib/zebra.h, ensure that RFC3542-required CMSG_SPACE and CMSG_LEN
are defined. Warn if alignment assumptions are made, since they are
i386-centric.
in lib/sockopt.h, declare that sockopt sizes are without
CMSG_SPACE-required padding - just simple sizeof.
in ospfd/ospf_packet.c, simply use CMSG_SPACE
This should remove all instances of CMSG_ALIGN from the source code.
This is a nonstandard, though rational, construct; quagga should use
only those defines in RFC3542.
|
|
* sockopt.h: Fix elif that should be an else.
|
|
* 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).
|
|
* sockopt.{c,h}: add sockopt_iphdrincl_swab_{htosys,systoh},
functions to change byte order between system IP_HDRINCL order
and host order.
|
|
* ripngd/ripngd.c: move setsockopt_so_recvbuf to lib.
* lib/sockopt.{c,h}: Add setsockopt_so_recvbuf, for ripd and ripngd.
* ripd/ripd.c: set receive buffer to a decent size, some systems
have low defaults. Problem noted and fix suggested by Stephan
Schweizer in [zebra 20967].

Thanks to Hasso for code review.
|
|
* sockopt.h: Define method-independent macro for callers of
get_ifindex to use for cmsg length.
|

2004-08-19 Paul Jakma <paul@dishone.st>
* sockopt.c: include sockopt.h

their purpose.

(setsockopt_pktinfo) update with previous and add comment re
AF_INET portability.

setsockopt_pktinfo.
(getsockopt_ipv4_pktinfo_ifindex) renamed to
getsockopt_ipv4_ifindex.
(getsockopt_ipv4_ifindex) rejiggling to reduce repeated
ifdef/elses. pktinfo case forgot to set ifindex.

set received ifindex sock option.
(getsockopt_pktinfo_ifindex) portably retrieve ifindex.
(getsockopt_cmsg_data) retrieve indicated control info from
