2011-12-07lib: fix compile warnings from set-never-usedStephen Hemminger
The if_dump code had empty loop, that caused set-never-used warning.
2011-03-23lib: fix more format warnings (#637)Christian Hammers
The following patch was also neccessary to compile. * command.c: (config_logmsg_cmd) use "%s" format spec * if.c: (connected_log) ditto
2011-03-21lib: Add a function to delete all interfacesTom Goff
if.c: (if_terminate) This adds a cleanup function that can be called when a daemon exits, similar to vty_terminate().
2009-08-28lib: if_lookup_by_name should be more robust to null argumentPaul Jakma
* if.c: (if_lookup_by_name) shouldn't crash just cause we got a NULL name
2009-06-12[cleanup] functions taking no args should be declared with void argsStephen Hemminger
Use Ansi-C prototypes rather than old K&R method of declaring function without arguments
2009-06-12[cleanup] add const attribute to lib/if.c::if_dumpStephen Hemminger
2009-06-12[cleanup] Convert XMALLOC/memset to XCALLOCStephen Hemminger
Simple conversion of XMALLOC/memset to XCALLOC
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.
2006-10-15[lib] Handle upgrade from SUNWzebra to Quagga for 'interface fooX:Y' commandsPaul Jakma
2006-10-14 Paul Jakma <paul.jakma@sun.com> * if.c: (general) Handle upgrades from SUNWzebra, which tried to track each logical interface as a seperate struct interface, to Quagga, which assigns only one struct interface per ifindex. (if_sunwzebra_get) Try decompose a logical interface name (fooX:Y) to the 'primary' name (fooX), for Solaris. (interface_cmd) Use if_sunwzebra_get on Solaris.
2006-06-15[zebra] remove internal if_flag_dump, use libzebras version.Paul Jakma
2006-06-15 Paul Jakma <paul.jakma@sun.com> * lib/if.c: (if_flag_dump) remove the whitespace indentation, callers should provide. * zebra/interface.c: (if_flag_dump_vty) redundant code, remove. (if_dump_vty) use libzebra if_flag_dump.
2005-11-032005-11-03 Paul Jakma <paul.jakma@sun.com>paul
* if.c: (connected_free) use MTYPE for connected label. memtypes.c: Add MTYPE_CONNECTED_LABEL
2005-10-262005-10-26 Paul Jakma <paul.jakma@sun.com>paul
* (general) Cleanup a some calls to XFREE,strdup, etc. to use the memory.h macros. * memtypes.c: Add MTYPE_IF_RMAP_NAME, MTYPE_PQUEUE, MTYPE_PQUEUE_DATA and MTYPE_HOST. * memtypes.h: update auto-built file. * if_rmap.c: Use MTYPE_IF_RMAP_NAME. * pqueue.c: Use the two MTYPE_PQUEUE mtypes for allocations.
2005-05-062005-05-06 Paul Jakma <paul@dishone.st>paul
* (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
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.

* if_ioctl.c: (interface_list_ioctl) Use if_get_by_name_len. * if_proc.c: (ifaddr_proc_ipv6) Increase size of ifname buffer to avoid overflow. * kernel_socket.c: (ifan_read) Use if_get_by_name_len. * if.h: Fix comments to reflect that if_lookup_by_name and if_get_by_name now require the argument strings to be NUL-terminated. * if.c: (if_lookup_by_name) Compare using strcmp. (if_get_by_name) Pass strlen(ifname) as 2nd arg to if_create.

Fix problems when netlink interfaces are renamed (same ifindex used for a new interface). Start cleaning up some problems with the way interface names are handled. * interface.c: (if_new_intern_ifindex) Remove obsolete function. (if_delete_update) After distributing the interface deletion message, set ifp->ifindex to IFINDEX_INTERNAL. (if_dump_vty) Detect pseudo interface by checking if ifp->ifindex is IFINDEX_INTERNAL. (zebra_interface) Check return code from interface_cmd.func. Do not set internal ifindex values to if_new_intern_ifindex(), since we now use IFINDEX_INTERNAL for all pseudo interfaces. * kernel_socket.c: (ifm_read) Fix code and comments to reflect that all internal interfaces now have ifp->ifindex set to IFINDEX_INTERNAL. * rt_netlink.c: (set_ifindex) New function used to update ifp->ifindex. Detects interface rename events by checking if that ifindex is already being used. If it is, delete the old interface before assigning the ifindex to the new interface. (netlink_interface, netlink_link_change) Call set_ifindex to update the ifindex. * if.h: Remove define for IFINDEX_INTERNBASE and add define IFINDEX_INTERNAL 0, since all internal (i.e. non-kernel) pseudo- interfaces should have ifindex set to 0. (if_new) Remove function. (if_delete_retain) New function to delete an interface without removing from iflist and freeing the structure. (ifname2ifindex) New function. * if.c: (if_new) Remove function (absorb into if_create). (if_create) Replace function if_new with call to calloc. Set ifp->ifindex to IFINDEX_INTERNAL. Fix off-by-one error in assert to check length of interface name. Add error message if interface with this name already exists. (if_delete_retain) New function to delete an interface without removing from iflist and freeing the structure. (if_delete) Implement with help of if_delete_retain. (ifindex2ifname) Reimplement using if_lookup_by_index. (ifname2ifindex) New function to complement ifindex2ifname. (interface) The interface command should check the name length and fail with a warning message if it is too long. (no_interface) Fix spelling in warning message. (if_nametoindex) Reimplement using if_lookup_by_name. (if_indextoname, ifaddr_ipv4_lookup) Reimplement using if_lookup_by_index. * bgp_zebra.c: (bgp_interface_delete) After deleting, set ifp->ifindex to IFINDEX_INTERNAL. * isis_zebra.c: (isis_zebra_if_del) Call if_delete_retain instead of if_delete, since it is generally not safe to remove interface structures. After deleting, set ifp->ifindex to IFINDEX_INTERNAL. (zebra_interface_if_lookup) Tighten up code. * ospf6_zebra.c: (ospf6_zebra_if_del) Previously, this whole function was commented out. But this is not safe: we should at least update the ifindex when the interface is deleted. So the new version updates the interface status and sets ifp->ifindex to IFINDEX_INTERNAL. (ospf6_zebra_route_update) Use if_indextoname properly. * ospf_vty.c: (show_ip_ospf_interface_sub) Show ifindex and interface flags to help with debugging. * ospf_zebra.c: (ospf_interface_delete) After deleting, set ifp->ifindex to IFINDEX_INTERNAL. (zebra_interface_if_lookup) Make function static. Tighten up code. * rip_interface.c: (rip_interface_delete) After deleting, set ifp->ifindex to IFINDEX_INTERNAL. * ripng_interface.c: (ripng_interface_delete) After deleting, set ifp->ifindex to IFINDEX_INTERNAL.

(bgp_show_community) Must use XFREE instead of free on string returned by buffer_getstr. * bgp_routemap.c: (set_community) Must use XFREE instead of free on string returned by buffer_getstr. * bgp_vty.c: (neighbor_description) Use argv_concat instead of buffer_getstr.
