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
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.

* interface.c: (if_delete_update) should always be available, not just on RTM_IFANNOUNCE/NETLINK systems. * kernel_socket.c: (ifan_read) only call if_delete_update when interface departs, dont if_delete, because we wish to retain interface configuration state even when interfaces are removed. (ifm_read) If we dont have RTM_IFANNOUNCE, then transitioning to down state is only chance we have to clean up interface in case it is deleted (eg Solaris down -> unplumb -> plumb up). * redistribute.c: (zebra_interface_delete_update) should always be available, we /will/ call it now on all systems, via if_delete_update. * zserv.c: (zsend_interface_delete) ditto (zsend_interface_address) Update the call-flow diagramme, to reflect that if_delete_update /is/ now called on all systems, potentially. * zserv.h: (zsend_interface_delete) unconditionally exported, as above.

* (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
2005-05-062005-05-06 Paul Jakma <paul.jakma@sun.com>paul
* zserv.h: Remove ZEBRA_PORT definition, its in lib/zebra.h now
2005-04-282005-04-28 Paul Jakma <paul.jakma@sun.com>paul
* 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.

* zserv.c: Must include network.h and buffer.h for non-blocking I/O. Remove global message_queue and t_write (need separate buffering for each client). (zebra_server_dequeue,zebra_server_enqueue) Remove functions related to old buggy buffering code. (zserv_delayed_close) New thread callback function to delete a client. (zserv_flush_data) New thread callback function to flush buffered data to client. (zebra_server_send_message) Rewritten to use buffer_write (so buffering of writes and non-blocking I/O work properly). (zsend_interface_add,zsend_interface_delete,zsend_interface_address, zsend_interface_update) Return 0 instead of -1 if !client->ifinfo (this is not really an error). Return value from zebra_server_send_message. (zsend_route_multipath,zsend_ipv4_nexthop_lookup, zsend_ipv4_import_lookup) Return value from zebra_server_send_message. (zsend_ipv6_nexthop_lookup) Fix scope to static, and return value from zebra_server_send_message. (zsend_router_id_update) Must use zebra_server_send_message instead of deprecated writen function. Return 0 instead of -1 if this client is not subscribed to router-id updates (since this is not really an error). (zread_interface_add) Change type to static int. If zsend_interface_add fails or zsend_interface_address fails, return -1 immediately (since the client has had an I/O error). (zread_interface_delete,zread_ipv4_add,zread_ipv4_delete, zread_ipv6_add,zread_ipv6_delete,zread_router_id_delete) Return 0 to indicate success. (zread_ipv4_nexthop_lookup) Return value from zsend_ipv4_nexthop_lookup. (zread_ipv4_import_lookup) Return value from zsend_ipv4_import_lookup. (zebra_read_ipv6) Remove unused function. (zread_ipv6_nexthop_lookup) Return value from zsend_ipv6_nexthop_lookup. (zread_router_id_add) Return value from zsend_router_id_update. (zebra_client_close) Call buffer_free(client->wb) and thread_cancel(client->t_suicide). (zebra_client_create) Allocate client->wb using buffer_new. (zebra_client_read) Support non-blocking I/O by using stream_read_try. Use ZEBRA_HEADER_SIZE instead of 3. (zebra_accept) Fix bug: reset accept thread at top. Make client socket non-blocking using the set_nonblocking function. (config_write_forwarding) Fix scope to static. (zebra_init) Remove initialization code for old buggy write buffering. * zserv.h: Add 2 new fields to struct zserv: struct buffer *wb (to enable buffered writes with non-blocking I/), and struct thread *t_suicide to support delayed close on I/O errors. * router-id.h: Remove prototypes for zread_router_id_add and zread_router_id_delete (their scope should be static to zserv.c).

2003-04-07[zebra 18626] move zebra socket paths to configure.acpaul
moved definition of the various socket paths from the per daemon header files into configure.ac. it will set the paths to be in the directory specified by --localstatedir=<prefix> or otherwise will try to guess as best it can ( a la pid file path detection - which probably should try reference ${prefix} too). the present hardcoded socket path, /tmp, isnt really correct. should be in /var somewhere really.
