* zebra: support FIB override routesTimo Teräs2016-02-261-0/+1
| | | | | | | | | | | | | | | | FIB override routes are for routing protocols that establish shortcut routes, or establish point-to-point routes that should not be redistributed. Namely this is useful NHRP daemon to come. Zebra is extended to select two entries from RIB the "best" entry from routing protocols, and the FIB entry to install to kernel. FIB override routes are never selected as best entry, and thus are never adverticed to other routing daemons. The best FIB override, or if it does not exist the otherwise best RIB is selected as FIB entry to be installed.

Build with HAVE_RTADV but !RTADV is broke after vrf, so for now, just define RTADV always if HAVE_RTADV is there. Signed-off-by: Timo Teräs <timo.teras@iki.fi>
* zebra, lib/memtypes.c: the netlink sockets work per VRFFeng Lu2015-06-031-0/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch lets the netlink sockets work per VRF. * The definition of "struct nlsock" is moved into zebra/rib.h. * The previous global variables "netlink" and "netlink_cmd" now become the members of "struct zebra_vrf", and are initialized in zebra_vrf_alloc(). * All relative functions now work for a specific VRF, by adding a new parameter which specifies the working VRF, except those functions in which the VRF ID can be obtained from the interface. * kernel_init(), interface_list() and route_read() are now also working per VRF, and moved from main() to zebra_vrf_enable(). * A new function kernel_terminate() is added to release the netlink sockets. It is called from zebra_vrf_disable(). * Correct VRF ID, instead of the previous VRF_DEFAULT, are now passed to the functions of processing interfaces or route entries.

* lib, zebra: move "struct vrf" to be a lib moduleFeng Lu2015-06-021-11/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously "struct vrf" is defined locally in zebra. Now it is moved to be a lib module. This is the first step to support multi-VRF in quagga. The implementation is splitted into small patches for the purpose of easy review. * lib: "struct vrf" with basic members is defined in vrf.c. The member "void *info" is for user data. Some basic functions are defined in vrf.c for adding/deleting/ looking up a VRF, scanning the VRF table and initializing the VRF module. The type "vrf_id_t" is defined specificly for VRF ID. * zebra: The previous "struct vrf" is re-defined as "struct zebra_vrf"; and previous "vrf" variables are renamed to "zvrf". The previous "struct vrf" related functions are removed from zbera_rib.c. New functions are defined to maintain the new "struct zebra_vrf". The names vrf_xxx are reserved for the functions in VRF module. So: - the previous vrf_table() are renamed to zebra_vrf_table(); - the previous vrf_static_table() are renamed to zebra_vrf_static_table(). The main logic is not changed. BTW: Add a statement to zebra_snmp.c telling that the SNMP is running only for the MIBs in the default VRF.

* zebra: make MRIB lookup behaviour switchableDavid Lamparter2015-02-061-0/+17
| | | | | | | | | | | | | | | depending on the usage scenario (and availability of multitopology IGP protocols, which is currently zero in Quagga), different approaches of Multicast RPF lookups are useful. Reference behaviours from commercial vendors are urib-only/mrib-only (Juniper, depending on inet.2 availability) and lowest-distance (Cisco). As we are currently without MT IGP support, mrib-first seems the most useful default for Quagga.

This ensures that the dest is not deleted even if there are no ribs hanging off of it. * zebra/zebra_fpm.c This file holds most of the code for interacting with the FPM. - If quagga was configured with '--enable-fpm', periodically try to connect to the FPM. - When the connection comes up, enqueue all relevent dests to the FPM queue. - When the FPM socket is readable, dequeue the next rib_dest_t from the FPM queue, encode it in to a message and send the message to the FPM. - When the connection to the FPM goes down, remove all dests from the FPM queue, and then start trying to connect to the FPM again. - Expose the following new operational commands: show zebra fpm stats clear zebra fpm stats * zebra/zebra_fpm_netlink.c - zfpm_netlink_encode_route(): Function to encode information about a rib_dest_t in netlink format. * zebra/zebra_fpm_private.h Private header file for the zebra FPM module. * zebra/zebra_fpm.h Header file exported by zebra FPM module to the rest of zebra. * zebra/debug.c Add the 'debug zebra fpm' command. * zebra/main.c Initialize the zebra-FPM code on startup. * zebra/misc_null.c Add stub for zfpm_trigger_update(). * zebra/Makefile.am - Include new file zebra_fpm.c in build. - Include zebra_fpm_netlink.c in build if HAVE_NETLINK is defined. * vtysh/Makefile.am Include zebra_fpm.c in list of files that define cli commands.

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
* [zebra] Bug #268, Fix race between add/delete of routes, sanitise rib queueingPaul Jakma2006-07-271-5/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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
* [zebra] arrange structs in padding-efficient manner and remove unused fieldPaul Jakma2006-03-301-18/+17
| | | | | | | | 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!
* [zebra] Fix mistake in previous commit and further compile warnings/errors.paul2005-11-241-0/+2
| | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * 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.
