2012-04-07zebra: read multipath routes and hw addr from netlinkJosh Bailey
* zebra/rt_netlink.c: - Pick up the hardware address of an interface when we receive a netlink link change message. Extract code for parsing the link-layer hardware address into a new function so we can reuse it. - netlink_routing_table(): Update to handle multipath routes. - netlink_route_change(): Update to handle multipath routes. Fix problem where the metric was not being read out. * zebra/zebra_rib.[ch]: Extern nexthop_ipv4_ifindex_add() -- it is now called from the netlink code.

2007-05-02[zebra] Routemap support on received routes, with 'set src' command (linux)Paul Jakma
2007-05-01 David L Stevens <dlstevens@us.ibm.com> * (general) These changes collectively add route-map and prefix-list support to zebra and fix a bug in "show route-map" (with no argument). * doc/main.texi: added route-map, prefix-list, ip protocol and set src documentation * lib/command.h: added PROTOCOL_NODE type * lib/log.c: (proto_name2num) new function, protocol name to number translation. * lib/routemap.c: (vty_show_route_map) fixed "show route-map" without route-map name * lib/routemap.h: added RMAP_ZEBRA type * lib/zebra.h: added proto_name2num() prototype * vtysh/extract.pl.in: added VTYSH_ZEBRA flag for route-map and plist * vtysh/Makefile.am: added zebra_routemap.c * vtysh/vtysh.h: added VTYSH_ZEBRA flag to VTYSH_RMAP * zebra/connected.c: (connected_up_ipv4) added src preference argument to rib_add_ipv4() * zebra/kernel_socket.c: (rtm_read) ditto * zebra/main.c: added prefix list initialization * zebra/Makefile.am: added zebra_routemap.c source file * zebra/rib.h: added generic address union "g_addr" and use in existing places that had an explicit union. Added "src" to struct nexthop. Added preferred src arg to nexthop_ipv4_add and rib_add_ipv4. * zebra/rt_netlink.c: (netlink_routing_table) set preferred source on netlink messages. (netlink_route_change) ditto (netlink_route_multipath) ditto. * zebra/rtread_getmsg.c: (handle_route_entry) added (NULL) src to rib_add_ipv4() call. * zebra/rtread_proc.c: (proc_route_read) ditto * zebra/zebra_rib.c: (nexthop_ipv4_add) add src argument. (nexthop_ipv4_ifindex_add) ditto (rib_add_ipv4) ditto (nexthop_active_check) Add route-map processing. * zebra/zebra_routemap.c: new file for zebra route-map commands. * zebra/zebra_vty.c: (ip_protocol_cmd) Apply route-map to protocol (vty_show_ip_route_detail) added "src" printing (vty_show_ip_route) ditto (show_ip_protocol_cmd) new command, list routemaps. (config_write_protocol) write out routemap protocl config. (zebra_vty_init) Install the new routemap protocol commands. * zebra/zserv.c: (zread_ipv4_add) added (NULL) src arg (zebra_init) init zebra route-maps. * zebra/zserv.h: add zebra_route_map_init
2006-07-27[zebra] Bug #268, Fix race between add/delete of routes, sanitise rib queueingPaul Jakma
2006-07-27 Paul Jakma <paul.jakma@sun.com> * rib.h: (struct rib) Add a route_node rn_status flag field, this has to be copied every time head RIB of a route_node changes. Remove the rib lock field, not needed - see below. Add a status field for RIB-private flags. * zebra_rib.c: Add a global for the workqueue hold time, useful for testing. (general) Fix for bug #268. Problem originally detailed by Simon Bryden in [quagga-dev 4001]. Essentially, add/delete of a RIB must happen /before/ the queue. Best-path selection (ie rib_process) and reaping of freed RIBs can then be done after queueing. Only the route_node is queued - no important RIB state (i.e. whether a RIB is to be deleted) is queued. (struct zebra_queue_node_t) Disappears, no longer need to track multiple things on the queue, only the route_node. (rib_{lock,unlock}) removed, RIBs no longer need to be refcounted, no longer queued. (rib_queue_qnode_del) Removed, deleted RIBs no longer deleted via the queue. (rib_queue_add_qnode) deleted (rib_queue_add) Only the route_node is queued for best-path selection, we can check whether it is already queued or not and avoid queueing same node twice - struct rib * argument is not needed. (rib_link/unlink) (un)link RIB from route_node. (rib_{add,del}node) Front-end to updates of a RIB. (rib_process) Reap any deleted RIBs via rib_unlink. Unset the route_node 'QUEUED' flag. (General) Remove calls to rib_queue_add where add/del node was called - not needed, update calls where not. Ignore RIB_ENTRY_REMOVEd ribs in loops through route_nodes
2006-03-30[zebra] arrange structs in padding-efficient manner and remove unused fieldPaul Jakma
2006-02-09 Paul Jakma <paul.jakma@sun.com> * rib.h: (struct {rib,nexthop}) Rearrange fields to avoid needless padding. (struct rib) Remove the indirect pointer, not used anywhere!
2005-11-24[zebra] Fix mistake in previous commit and further compile warnings/errors.paul
2005-11-24 Paul Jakma <paul.jakma@sun.com> * kernel_socket.h: New header for functions exported to sysctl methods. * kernel_socket.c: include previous. Remove static qualifier from couple of functions which are used by sysctl methods, incorrectly added in previous commit. Add a workaround for a bogus gcc warning to the RTA_ macros. * Makefile.am: Add kernel_socket.h to noinst_HEADERS * if_sysctl.c: include rt.h and kernel_socket.h and remove redundant prototypes. * rtread_sysctl.c: ditto. (route_read) fix mismatch of return values. * {rt,zserv,rib}.h: Include lib headers depended on.
2005-09-24 * rib.h: Add note about behaviour of rib_add_ipv[46]* functions -hasso
add is treated as implicit withdraw.
2005-08-27 * zebra_rib.c, rib.h: Add distance and metric arguments to thehasso
rib_add_ipv6() function so that IPv6 routes in RIB can have correct metric. No IPv6 routing daemon uses distance yet though. * zserv.c, connected.c, kernel_socket.c, rt_netlink.c, rtread_proc.c,zserv.c: Pass metric and distance info to the rib_add_ipv6(). Forwardport from stable branch.
2005-06-282005-06-28 Paul Jakma <paul.jakma@sun.com>paul
* (global) Extern and static'ification, with related fixups of declarations, ensuring files include their own headers, etc. if_ioctl.c: (interface_info_ioctl) fix obvious arg mis-order in list loop

* rib.h: (struct rib) Add lock field for refcounting. * zserv.h: (struct zebra_t) Add a ribq workqueue to the zebra 'master' struct. * zserv.c: (zread_ipv4_add) XMALLOC then memset should be XCALLOC. * zebra_rib.c: Clean up refcounting of route_node, make struct rib refcounted and convert rib_process to work-queue. In general, rib's should be rib_addnode'd and delnode'd to route_nodes, and these symmetrical functions will manage the locking of referenced route_node and freeing of struct rib - rather than having users manage each seperately - with much scope for bugs.. (newrib_free) removed and replaced with rib_lock (rib_lock) new function, check state of lock and increment. (rib_unlock) new function, check lock state and decrement. Free struct rib if refcount hits 0, freeing struct nexthop's, as newrib_free did. (rib_addnode) Add RIB to route_node, locking both. (rib_delnode) Delete RIB from route_node, unlocking each. (rib_process) Converted to a work-queue work function. Functional changes are minimal, just arguments, comments and whitespace. (rib_queue_add_qnode) Helper function to setup a ribq item. (rib_queue_add) Helper function, same arguments as old rib_process, to replace in callers of rib_process. (rib_queue_qnode_del) ribq deconstructor. (rib_queue_init) Create the ribq. (rib_init) call rib_queue_init. (remainder) Sanitise refcounting of route_node's. Convert to rib_queue_add, rib_addnode and rib_delnode. Change XMALLOC/memset to XCALLOC. Remove calls to nexthop_delete and nexthop_free.

* lib/version.h: add ZEBRA_URL (unused for now) * lib/vty.c: CMD_ERR_NOTHING_TODO when reading conf file should not be fatal. slight reformating. * ospfd/ospf_zebra.c: ignore reject/blackhole routes if zebra sends these type of routes. probably should be a new type of route to allow daemons to more easily choose whether to redistribute them - rathen than just a flag (eg for reject/blackhole). reorder the is_prefix_default test for ZEBRA_IPV4_ROUTE_DELETE to avoid the inverted test - slightly more readable. * redhat/zebra.spec.in: Add ospfapi port to services file, if with_ospfapi. * zebra/rib.h: Change nexthop types to an enum. * zebra/rt_netlink.c: run it through indent -nut. Add nexthop_types_desc[] descriptive array for nexthop types. (netlink_route_multipath) debug statements indicate which branch they are in and print out nexthop type. * zebra/zebra_rib.c: slight reformatting. * zebra/zebra_vty.c: Pass ZEBRA_FLAG_BLACKHOLE flag to static_add_ipv4() if Null0 route is configured. print out Null0 if STATIC_IPV4_BLACKHOLE route, and ignore flags (shouldnt be possible to set flags from vty) for config and show route.
