* rip_interface.c: (rip_interface_multicast_set) get rid
of extraneous if_pointopoint arg. ifp is accessible via connected.
pass connected->ifp->ifindex to setsockopt_multicast_ipv4.
* ripd.c: (rip_send_packet) update call to
rip_interface_multicast_set
* ripd.h: update rip_interface_multicast_set prototype
|
|
* ripd.h: Add define for the RIPv2 Authentication Data family
Move the auth type defines up to where other defines live.
Add RIP_AUTH_MD5_COMPAT_SIZE, for backwards compatible
md5->auth_len size. Add md5_auth_len field to struct
rip_interface: (rip_interface_new) Init md5_auth_len to compatible
size.
(ip_rip_authentication_mode_cmd) Extended to handle setting
md5 auth-length. Appropriate aliases added.
(no_ip_rip_authentication_mode_cmd) Reset md5_auth_len to
compatible size.
(rip_interface_config_write) Teach it about md5_auth_len.
_always_ write out the auth-length, so that everyone will get
the setting in their config file, and hence allow for a future
change of default for md5_auth_len to be less painful - every md5
user will have this setting in their config file.
ripd.c: (rip_packet_dump) Change nasty hard coded constants to
symbolic defines. Change various tests of 'ntoh.(variable) ==
constant' to test 'variable == ntoh.(constant)'. Clean up
indentation on some long lines.
(rip_auth_simple_password) ditto.
(rip_auth_md5) ditto, also add length argument and sanity check
md5 data offset field. Sanity check md5 auth length, accept RFC
or old-ripd/cisco lengths.
(rip_auth_md5_set) as per (rip_packet_dump), also write out
the configured md5 auth length for the interface (old-ripd or rfc)
(rip_read) as per (rip_packet_dump)
(rip_write_rte) ditto
(rip_response_process) ditto
(rip_write_rte) ditto

* rip_interface.c: obsolete unbind code in
rip_interface_multicast_set, and instead do the more portable
(though slower) method of creating a socket for each outgoing packet
and binding the source address on the new socket.
* rip_interface.c, ripd.c, ripd.h: Modify rip_request_send so that
source address is determined by the caller of rip_request_send for
ripv1 packets and non-multicast interfaces (rip_request_send loops
over all connected address in all other cases).
* rip_send_packet: don't send packets with source set to
ZEBRA_IFA_SECONDARY connected addresses; improved debug messages;
|
|
* ripd/ripd.c: (rip_send_packet) use rip->sock for mcast sends,
instead of creating one socket per send. send source addr to
rip_update_interface.
(rip_update_process) should send an update on every connected
network for each interface.
(rip_request_send) should send a request on every connected
network for each interface.
* ripd/ripd.h: update prototype for rip_interface_multicast_set
* ripd/rip_interface.c: (rip_interface_multicast_set) reorganized
so that it can be called repeatedly for aliased interfaces (on
multiple networks).
|

* zebra/connected.c: revert the 'generic PtP' patch as it causes
far too many problems. People who use FreeSWAN should investigate
native linux ipsec.
* zebra/rt_netlink.c: ditto
* lib/if.c: ditto
* ripd/ripd.h: ditto
* ripd/ripd.c: ditto
* ripd/rip_interface.c: ditto
* ospfd/ospfd.c: ditto
* ospfd/ospf_snmp.c: ditto
* bgpd/bgp_nexthop.c: ditto

Subject: [zebra 12403] patch for ripd to accept any version of RIP
by default
The default Cisco IOS behavior is to send RIP version 1 packets and receive
version 1 and version 2 packets. But zebra version 0.92a sends and receives
only version 2 packets by default.
I have patched the code to change zebra's default behavior to sending
version 2 packets (same as before) but receiving both versions. While
this is still not identical to Cisco's behavior, it does now accept
packets of both versions and retains backwards compatibility with
zebra configurations.

Subject: [zebra 12406] patch for ripd to support "passive-interface
default" behavior
In Cisco IOS, the router rip passive-interface subcommand can accept
an interface name of "default". In that cases, all interfaces are set
to be passive by default, and you must explicitly make it non-passive
by using the "no passive-interface <ifname>" command if you want updates
to go to that interface.
<command implemented for zebra>

moved definition of the various socket paths from the
per daemon header files into configure.ac. it will set the paths to
be in the directory specified by --localstatedir=<prefix> or
otherwise will try to guess as best it can ( a la pid file path
detection - which probably should try reference ${prefix} too).
the present hardcoded socket path, /tmp, isnt really correct. should
be in /var somewhere really.
