2012-06-25snmp: let handlers accept OID from a lesser prefixVincent Bernat
Most table handlers do not expect to be given an OID whose prefix is outside what they can handle. This is not a problem with the SMUX implementation since it always correct the OID such that the prefix matches. However, this is not the case for the AgentX implementation. A new function, smux_header_table() is used to do this normalization.
2012-06-25agentx: handle SNMP trapsVincent Bernat
smux_trap() signature has been changed to provide appropriate level information to send SNMPv2 notifications. This includes the addition of the enterprise OID to use (from which is derived the SNMP trap OID) and the MIB registry to locate the appropriate function for variable bindings provided by the trap. The SMUX implementation has been updated but ignore the provided enterprise OID. Instead, it still uses the SMUX peer OID to keep compatibility with previous versions of Quagga. The SMUX implementation also ignores the provided MIB registry since it uses smux_get() function to grab the appropriate values. This is not possible with the AgentX implementation since there is no such function provided by NetSNMP.
2012-06-25smux: drop findVar element from trap object structVincent Bernat
This element was not unused.
2012-06-25smux: remove `tick` argument from smux_trap()Vincent Bernat
smux_trap() contains an argument whose use appears to be to set sysUpTime.0/timestamp field in SNMP trap. However, this value is not used in smux_trap(). Moreover, it is expected that this field is the value of sysUpTime.0 when the trap was sent and not any other time related to the trap. To avoid any confusion, we remove this field from the signature of the function.
2012-06-25build: only define HAVE_SNMPVincent Bernat
NetSNMP is the only SNMP implementation for Quagga. We don't need two different symbols.

2007-03-14[ospfd] Return SNMP standard neighbor state values, not quagga internal onesAndrew J. Schorr
2007-03-14 Andrew J. Schorr <ajschorr@alumni.princeton.edu> * ospf_snmp.c: (ospf_snmp_neighbor_state) New function to map internal quagga neighbor states to SNMP standard values. (ospfNbrEntry) Call new ospf_snmp_neighbor_state function.
2006-12-12[PtP over ethernet] New peer flag allows much more addressing flexibilityAndrew J. Schorr
2006-12-12 Andrew J. Schorr <ajschorr@alumni.princeton.edu> * if.h: (struct connected) Add new ZEBRA_IFA_PEER flag indicating whether a peer address has been configured. Comment now shows the new interpretation of the destination addr: if ZEBRA_IFA_PEER is set, then it must contain the destination address, otherwise it may contain the broadcast address or be NULL. (CONNECTED_DEST_HOST,CONNECTED_POINTOPOINT_HOST) Remove obsolete macros that were specific to IPv4 and not fully general. (CONNECTED_PEER) New macro to check ZEBRA_IFA_PEER flag. (CONNECTED_PREFIX) New macro giving the prefix to insert into the RIB: if CONNECTED_PEER, then use the destination (peer) address, else use the address field. (CONNECTED_ID) New macro to come up with an identifying address for the struct connected. * if.c: (if_lookup_address, connected_lookup_address) Streamline logic with new CONNECTED_PREFIX macro. * prefix.h: (PREFIX_COPY_IPV4, PREFIX_COPY_IPV6) New macros for better performance than the general prefix_copy function. * zclient.c: (zebra_interface_address_read) For non-null destination addresses, set prefixlen to equal the address prefixlen. This is needed to get the new CONNECTED_PREFIX macro to work properly. * connected.c: (connected_up_ipv4, connected_down_ipv4, connected_up_ipv6, connected_down_ipv6) Simplify logic using the new CONNECTED_PREFIX macro. (connected_add_ipv4) Set prefixlen in destination addresses (required by the CONNECTED_PREFIX macro). Use CONNECTED_PEER macro instead of testing for IFF_POINTOPOINT. Delete invalid warning message. Warn about cases where the ZEBRA_IFA_PEER is set but no destination address has been supplied (and turn off the flag). (connected_add_ipv6) Add new flags argument so callers may set the ZEBRA_IFA_PEER flag. If peer/broadcast address satisfies IN6_IS_ADDR_UNSPECIFIED, then reject it with a warning. Set prefixlen in destination address so CONNECTED_PREFIX will work. * connected.h: (connected_add_ipv6) Add new flags argument so callers may set the ZEBRA_IFA_PEER flag. * interface.c: (connected_dump_vty) Use CONNECTED_PEER macro to decide whether the destination address is a peer or broadcast address (instead of checking IFF_BROADCAST and IFF_POINTOPOINT). * if_ioctl.c: (if_getaddrs) Instead of setting a peer address only when the IFF_POINTOPOINT is set, we now accept a peer address whenever it is available and not the same as the local address. Otherwise (no peer address assigned), we check for a broadcast address (regardless of the IFF_BROADCAST flag). And must now pass a flags value of ZEBRA_IFA_PEER to connected_add_ipv4 when a peer address is assigned. The same new logic is used with the IPv6 code as well (and we pass the new flags argument to connected_add_ipv6). (if_get_addr) Do not bother to check IFF_POINTOPOINT: just issue the SIOCGIFDSTADDR ioctl and see if we get back a peer address not matching the local address (and set the ZEBRA_IFA_PEER in that case). If there's no peer address, try to grab SIOCGIFBRDADDR regardless of whether IFF_BROADCAST is set. * if_ioctl_solaris.c: (if_get_addr) Just try the SIOCGLIFDSTADDR ioctl without bothering to check the IFF_POINTOPOINT flag. And if no peer address was found, just try the SIOCGLIFBRDADDR ioctl without checking the IFF_BROADCAST flag. Call connected_add_ipv4 and connected_add_ipv6 with appropriate flags. * if_proc.c: (ifaddr_proc_ipv6) Must pass new flags argument to connected_add_ipv6. * kernel_socket.c: (ifam_read) Must pass new flags argument to connected_add_ipv6. * rt_netlink.c: (netlink_interface_addr) Copy logic from iproute2 to determine local and possible peer address (so there's no longer a test for IFF_POINTOPOINT). Set ZEBRA_IFA_PEER flag appropriately. Pass new flags argument to connected_add_ipv6. (netlink_address) Test !CONNECTED_PEER instead of if_is_broadcast to determine whether the connected destination address is a broadcast address. * bgp_nexthop.c: (bgp_connected_add, bgp_connected_delete) Simplify logic by using new CONNECTED_PREFIX macro. * ospf_interface.c: (ospf_if_is_configured, ospf_if_lookup_by_prefix, ospf_if_lookup_recv_if) Simplify logic using new CONNECTED_PREFIX macro. * ospf_lsa.c: (lsa_link_ptop_set) Using the new CONNECTED_PREFIX macro, both options collapse into the same code. * ospf_snmp.c: (ospf_snmp_if_update) Simplify logic using new CONNECTED_ID macro. (ospf_snmp_is_if_have_addr) Simplify logic using new CONNECTED_PREFIX macro. * ospf_vty.c: (show_ip_ospf_interface_sub) Use new CONNECTED_PEER macro instead of testing the IFF_POINTOPOINT flag. * ospfd.c: (ospf_network_match_iface) Use new CONNECTED_PEER macro instead of testing with if_is_pointopoint. And add commented-out code to implement alternative (in my opinion) more elegant behavior that has no special-case treatment for PtP addresses. (ospf_network_run) Use new CONNECTED_ID macro to simplify logic. * rip_interface.c: (rip_interface_multicast_set) Use new CONNECTED_ID macro to simplify logic. (rip_request_interface_send) Fix minor bug: ipv4_broadcast_addr does not give a useful result if prefixlen is 32 (we require a peer address in such cases). * ripd.c: (rip_update_interface) Fix same bug as above.

* (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.
2005-03-27 * ospf_snmp.c: Don't crash in snmp query if ospf instance doesn'thasso
exist at all. [backport candidate]
2004-10-19OK. Here it is - PtP patch from Andrew J. Schorr. No problems with ospfd,hasso
ripd might need some more testing though.
