* pimd: Cleanup interface startupDonald Sharp2015-10-271-16/+10
| | | | | | | This patch cleans up some interface startup, removes duplicate debug messages and protects against some always being displayed. Signed-off-by: Donald Sharp <sharpd@cumulusnetworks.com>
* pimd: Cleanup zebra debugs to be protected by debug commandsDonald Sharp2015-10-271-1/+1
| | | | | | | | pimd is very chatty without any pim debugs turned on. This commit fixes a bunch of the debugs to be protected by appropriate pim debug statement. Signed-off-by: Donald Sharp <sharpd@cumulusnetworks.com>
* lib: zclient.c remove extern struct thread_master *Donald Sharp2015-10-271-2/+2
| | | | | | | | | | | | zclient.c depended upon link time inclusion of a extern struct thread_master *master. This is a violation of the namespace of the calling daemon. If a library needs the pointer pass it in and save it for future use. This code change also makes the zclient code consistent with the other lib functions that need to schedule work on your behalf Signed-off-by: Donald Sharp <sharpd@cumulusnetworks.com>
* *: add VRF ID in the API message headerFeng Lu2015-06-031-16/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The API messages are used by zebra to exchange the interfaces, addresses, routes and router-id information with its clients. To distinguish which VRF the information belongs to, a new field "VRF ID" is added in the message header. And hence the message version is increased to 3. * The new field "VRF ID" in the message header: Length (2 bytes) Marker (1 byte) Version (1 byte) VRF ID (2 bytes, newly added) Command (2 bytes) - Client side: - zclient_create_header() adds the VRF ID in the message header. - zclient_read() extracts and validates the VRF ID from the header, and passes the VRF ID to the callback functions registered to the API messages. - All relative functions are appended with a new parameter "vrf_id", including all the callback functions. - "vrf_id" is also added to "struct zapi_ipv4" and "struct zapi_ipv6". Clients need to correctly set the VRF ID when using the API functions zapi_ipv4_route() and zapi_ipv6_route(). - Till now all messages sent from a client have the default VRF ID "0" in the header. - The HELLO message is special, which is used as the heart-beat of a client, and has no relation with VRF. The VRF ID in the HELLO message header will always be 0 and ignored by zebra. - Zebra side: - zserv_create_header() adds the VRF ID in the message header. - zebra_client_read() extracts and validates the VRF ID from the header, and passes the VRF ID to the functions which process the received messages. - All relative functions are appended with a new parameter "vrf_id". * Suppress the messages in a VRF which a client does not care: Some clients may not care about the information in the VRF X, and zebra should not send the messages in the VRF X to those clients. Extra flags are used to indicate which VRF is registered by a client, and a new message ZEBRA_VRF_UNREGISTER is introduced to let a client can unregister a VRF when it does not need any information in that VRF. A client sends any message other than ZEBRA_VRF_UNREGISTER in a VRF will automatically register to that VRF. - lib/vrf: A new utility "VRF bit-map" is provided to manage the flags for VRFs, one bit per VRF ID. - Use vrf_bitmap_init()/vrf_bitmap_free() to initialize/free a bit-map; - Use vrf_bitmap_set()/vrf_bitmap_unset() to set/unset a flag in the given bit-map, corresponding to the given VRF ID; - Use vrf_bitmap_check() to test whether the flag, in the given bit-map and for the given VRF ID, is set. - Client side: - In "struct zclient", the following flags are changed from "u_char" to "vrf_bitmap_t": redist[ZEBRA_ROUTE_MAX] default_information These flags are extended for each VRF, and controlled by the clients themselves (or with the help of zclient_redistribute() and zclient_redistribute_default()). - Zebra side: - In "struct zserv", the following flags are changed from "u_char" to "vrf_bitmap_t": redist[ZEBRA_ROUTE_MAX] redist_default ifinfo ridinfo These flags are extended for each VRF, as the VRF registration flags. They are maintained on receiving a ZEBRA_XXX_ADD or ZEBRA_XXX_DELETE message. When sending an interface/address/route/router-id message in a VRF to a client, if the corresponding VRF registration flag is not set, this message will not be dropped by zebra. - A new function zread_vrf_unregister() is introduced to process the new command ZEBRA_VRF_UNREGISTER. All the VRF registration flags are cleared for the requested VRF. Those clients, who support only the default VRF, will never receive a message in a non-default VRF, thanks to the filter in zebra. * New callback for the event of successful connection to zebra: - zclient_start() is splitted, keeping only the code of connecting to zebra. - Now zclient_init()=>zclient_connect()=>zclient_start() operations are purely dealing with the connection to zbera. - Once zebra is successfully connected, at the end of zclient_start(), a new callback is used to inform the client about connection. - Till now, in the callback of connect-to-zebra event, all clients send messages to zebra to request the router-id/interface/routes information in the default VRF. Of corse in future the client can do anything it wants in this callback. For example, it may send requests for both default VRF and some non-default VRFs.
