2006-04-28[ripd] Fix logic to send updates on all connected addresses.Andrew J. Schorr
2006-04-28 Andrew J. Schorr <ajschorr@alumni.princeton.edu> * ripd.c: (rip_update_process) Try to fix the logic for sending an updated on each connected network. The new code will attempt to send the update on each connected network, whereas the previous code seemed to be attempting to avoid sending more than one RIPv1 update on a given interface, but was coded incorrectly. The actual effect of the old code was to send an update only on the first connected address in the cases where the interface is not multicast, or RIPv2 is not being used.

2006-01-17[ripd] Fix verification of received MD5 authenticated packetspaul
2006-01-17 Paul Jakma <paul.jakma@sun.com> * ripd.c: (rip_auth_md5) remove pdigest, not needed. Use a local buffer for the auth_str, where it can be properly nul padded. Do so, hence fixing MD5 authentication. Key looked up via key ring should be used in preference to the RIPv1 simple password, not other way around. No need to copy around digests, we can reference them directly. The auth_len received can't be trusted, some implementations lie (e.g. older ripd). (rip_auth_md5_ah_write) rename len local variable to doff to be consistent with other functions. (rip_auth_header_write) add the missing return. (rip_auth_md5_set) use the proper constructs to access stream.

* ripd.c: (rip_response_process) Instead of calling rip_interface.c:if_valid_neighbor(), call the equivalent library function if_lookup_address(). * rip_interface.c: (if_valid_neighbor) Remove function, since it is essentially equivalent to the if_lookup_address() library function. * ripd.h: (if_valid_neighbor) Remove function declaration.
2005-10-252005-10-26 Paul Jakma <paul.jakma@sun.com>paul
* ripd.c: Update couple more functions to specify void explicitely.
2005-10-252005-10-26 Paul Jakma <paul.jakma@sun.com>paul
* (general) static/extern functions and definitions. * rip_interface.h: new file, export the public functions from rip_interface.c
2005-10-192005-10-17 Vincent Jardin <vincent.jardin@6wind.com>jardin
* ripd.c: rip_create_socket() for each packet, it does not bind to the proper interfaces because we forget to use the from address when it is specified.

* zebra.h: Declare new functions zebra_route_string() and zebra_route_char(). * log.c: (zroute_lookup,zebra_route_string,zebra_route_char) New functions to map zebra route numbers to strings. * zebra_vty.c: (route_type_str) Remove obsolete function: use new library function zebra_route_string() instead. Note that there are a few differences: for IPv6 routes, we now get "ripng" and "ospf6" instead of the old behavior ("rip" and "ospf"). (route_type_char) Remove obsolete function: ues new library function zebra_route_char() instead. Note that there is one difference: the old function returned 'S' for a ZEBRA_ROUTE_SYSTEM route, whereas the new one returns 'X'. (vty_show_ip_route_detail,vty_show_ipv6_route_detail) Replace route_type_str() with zebra_route_string(). (vty_show_ip_route,vty_show_ipv6_route) Replace route_type_char() with zebra_route_char(). * bgp_vty.c: (bgp_config_write_redistribute) Use new library function zebra_route_string instead of a local hard-coded table. * ospf6_asbr.c: Remove local hard-coded tables zroute_name and zroute_abname. Change the ZROUTE_NAME macro to use new library function zebra_route_string(). Remove the ZROUTE_ABNAME macro. (ospf6_asbr_external_route_show): Replace ZROUTE_ABNAME() with a call to zebra_route_char(), and be sure to fix the format string, since we now have a char instead of a char *. * ospf6_zebra.c: Remove local hard-coded tables zebra_route_name and zebra_route_abname. Note that the zebra_route_name[] table contained mixed-case strings, whereas the zebra_route_string() function returns lower-case strings. (ospf6_zebra_read_ipv6): Change debug message to use new library function zebra_route_string() instead of zebra_route_name[]. (show_zebra): Use new library function zebra_route_string() instead of zebra_route_name[]. * ospf_dump.c: Remove local hard-coded table ospf_redistributed_proto. (ospf_redist_string) New function implemented using new library function zebra_route_string(). Note that there are a few differences in the output that will result: the new function returns strings that are lower-case, whereas the old table was mixed case. Also, the old table mapped ZEBRA_ROUTE_OSPF6 to "OSPFv3", whereas the new function returns "ospf6". * ospfd.h: Remove extern struct message ospf_redistributed_proto[], and add extern const char *ospf_redist_string(u_int route_type) instead. * ospf_asbr.c: (ospf_external_info_add) In two messages, use ospf_redist_string instead of LOOKUP(ospf_redistributed_proto). * ospf_vty.c: Remove local hard-coded table distribute_str. (config_write_ospf_redistribute,config_write_ospf_distribute): Use new library function zebra_route_string() instead of distribute_str[]. * ospf_zebra.c: (ospf_redistribute_set,ospf_redistribute_unset, ospf_redistribute_default_set,ospf_redistribute_check) In debug messages, use ospf_redist_string() instead of LOOKUP(ospf_redistributed_proto). * rip_zebra.c: (config_write_rip_redistribute): Remove local hard-coded table str[]. Replace str[] with calls to new library function zebra_route_string(). * ripd.c: Remove local hard-coded table route_info[]. (show_ip_rip) Replace uses of str[] with calls to new library functions zebra_route_char and zebra_route_string. * ripng_zebra.c: (ripng_redistribute_write) Remove local hard-coded table str[]. Replace str[i] with new library function zebra_route_string(i). * ripngd.c: Remove local hard-coded table route_info[]. (show_ipv6_ripng) Use new library function zebra_route_char() instead of table route_info[].

* ripd.c: (general) Fix previous commit, broke multicast bind and hence setting of source port, which broke communication with non-borken ripd. Fix removes more stuff from rip_interface.c than it adds to ripd.c ;) (rip_create_socket) the to argument really is a from argument, rename it. Set the source port to RIP port unconditionally, it's required. (rip_send_packet) Set from address correctly for multicast. (rip_output_process) trivial: num can be BSS specified, rather than in body. * rip_interface.c: (rip_interface_multicast_set) strip out redundant stuff related to bind, which rip_create_socket does. Just make it set the multicast socket option, as per the interface concerned, no more.
2005-06-032005-06-03 Paul Jakma <paul.jakma@sun.com>paul
* ripd.c: (rip_create_socket) Make it static. Remove the getservbyname stuff, as RFC2453 3.9.2 says non-RIP port messages should be discarded, quagga doesnt accept them, no need to lookup port. Take a 'to' argument, if socket should be bound to something else. setsockopt_so_recvbuf might need privs, move it to the raised privileges section. dont forget to close the socket if bind fails. (rip_send_packet) use strncpy, just in case (address is under our control anyway, but still). dont duplicate rip_create_socket - just use it. (rip_create) rip_create_socket takes an argument now, modify.
2005-06-032005-06-03 Paul Jakma <paul.jakma@sun.com>paul
* ripd.c: (rip_create_socket) move it up so rip_send_packet can use it too.
2005-05-292005-05-29 Paul Jakma <paul@dishone.st>paul
* ripd.c: (rip_output_process) fix error which crept in my previous rip auth untanglement commit - it had become impossible to not have authentication (even for v1).
2005-04-072005-04-07 Paul Jakma <paul.jakma@sun.com>paul
* (global): Fix up list loops to match changes in lib/linklist, and some basic auditing of usage. * configure.ac: define QUAGGA_NO_DEPRECATED_INTERFACES * HACKING: Add notes about deprecating interfaces and commands. * lib/linklist.h: Add usage comments. Rename getdata macro to listgetdata. Rename nextnode to listnextnode and fix its odd behaviour to be less dangerous. Make listgetdata macro assert node is not null, NULL list entries should be bug condition. ALL_LIST_ELEMENTS, new macro, forward-referencing macro for use with for loop, Suggested by Jim Carlson of Sun. Add ALL_LIST_ELEMENTS_RO for cases which obviously do not need the "safety" of previous macro. LISTNODE_ADD and DELETE macros renamed to ATTACH, DETACH, to distinguish from the similarly named functions, and reflect their effect better. Add a QUAGGA_NO_DEPRECATED_INTERFACES define guarded section with the old defines which were modified above, for backwards compatibility - guarded to prevent Quagga using it.. * lib/linklist.c: fix up for linklist.h changes. * ospf6d/ospf6_abr.c: (ospf6_abr_examin_brouter) change to a single scan of the area list, rather than scanning all areas first for INTER_ROUTER and then again for INTER_NETWORK. According to 16.2, the scan should be area specific anyway, and further ospf6d does not seem to implement 16.3 anyway.

* (global) Update code to match stream.h changes. stream_get_putp effectively replaced with stream_get_endp. stream_forward renamed to stream_forward_getp. stream_forward_endp introduced to replace some previous setting/manual twiddling of putp by daemons. * lib/stream.h: Remove putp. Update reference to putp with endp. Add stream_forward_endp, which daemons were doing manually. Rename stream_forward to stream_forward_getp. lib/stream.c: Remove/update references to putp. introduce stream_forward_endp.

* ripd.c: Untangle the construction of RIP auth data. (rip_auth_prepare_str_send) new helper function, prepare correct key string. (rip_auth_simple_write) new helper, write out the rip simple password auth psuedo-RTE. (rip_auth_md5_ah_write) new helper, write out the MD5 auth-header psuedo-RTE. (rip_auth_header_write) new helper, write out correct auth header data / psuedo-RTE. (rip_auth_md5_set) rip out the memmove and writing of the auth header psuedo-RTE. So that all that is left is to write the trailing auth digest, and update digest offset field in the original header. (rip_write_rte) rip out writing of RIP header, writing of simple auth data psuedo-RTE. Make it do what its name suggests, write out actual RTEs. (rip_output_process) remove the incorrect additional decrements of rtemax. Prepare the auth_str, which simple or MD5 auth will need. Move write out of RIP header and auth data to inside the loop. Adjust paramaters as required.

* ripd.c: Collapse redundant passing of various address structs, struct interface and struct connected as arguments to functions down to two key arguments, namely struct connected and, possibly, address of source/destination. Testing for RIPv1 would be useful. (rip_read) lookup struct connected for the received packet, pass it on. * rip_interface.c: With previous changes, we no longer have to tread carefully with struct connected, as it will always be there and valid.
2004-10-19OK. Here it is - PtP patch from Andrew J. Schorr. No problems with ospfd,hasso

(various) Add static qualifier to internal functions. (prefix_list_type_str) extraneous breaks in switch statement. (ip_prefix_list_description_cmd) buffer_putstr doesnt need cast * stream.h: depends on plist.h and export stream_put_prefix * vty.c: (vty_<telnet option build functions>) should use unsigned char, telnet options are 0 -> 255. * zclient.c: various u_char<->char type cleanups. * zebra.h: Having to define CMSG_* can apply to more than just BSDI_NRL. * ripd.c: (rip_distribute_update_all) distribute list hook function pointer prototype requires struct prefix_list * arg.

* 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.

Compile and warning fixes for the ripd 'passive-interface default' patch.
2003-06-07From: Andrew J. Schorr <aschorr@telemetry-investments.com>paul
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.
2003-06-07From: Andrew J. Schorr <aschorr@telemetry-investments.com>paul
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>
