* quagga: Remove double read of streamDonald Sharp2016-03-111-1/+3
| | | | | | | | | | The addition of a MIN(X,Y) with a stream_getc in the Y causes a double read of the stream due to the way that MIN is defined. This fix removes a crash in all protocols. Signed-off-by: Donald Sharp <sharpd@cumulusnetworks.com>
* lib: Check prefix length from zebra is sensiblePaul Jakma2016-03-081-1/+1
| | | | | | | | | | | | | * zclient.c: prefix length on router-id and interface address add messages not sanity checked. fix. * */*_zebra.c: Prefix length on zebra route read was not checked, and clients use it to write to storage. An evil zebra could overflow client structures by sending overly long prefixlen. Prompted by discussions with: Donald Sharp <sharpd@cumulusnetworks.com>

* lib: zclient.c remove extern struct thread_master *Donald Sharp2015-10-273-4/+4
| | | | | | | | | | | | 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>
* build: Remove the old PIC/PIE patch, let libtool sort it outPaul Jakma2015-09-031-2/+1
| | | | | | | * Remove the old change from '08 to add in PIE arguments at automake level. Versions of libtool since then know how to deal with -fpie and do the right thing according to whether its building shared or executable objects. So just pass '-fpie' as CFLAG and let libtool do its thing.
* Quagga: Fix code to use srandom/randomDonald Sharp2015-06-211-2/+2

* *: add VRF ID in the API message headerFeng Lu2015-06-033-43/+54
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* *: call if_init()/if_terminate() from vrf_init()/vrf_terminate()Feng Lu2015-06-022-1/+3
| | | | | | | | | | | | | | | | | | Later, an interface will belong to a specific VRF, and the interface initialization will be a part of the VRF initialization. So now call if_init() from vrf_init(), and if_terminate() from vrf_terminate(). Daemons have the according changes: - if if_init() was called or "iflist" was initialized, now call vrf_init() instead; - if if_terminate() was called or "iflist" was destroyed, now call vrf_terminate() instead.

* ripngd: allow to enable/disable the ECMP featureFeng Lu2015-05-273-5/+103
| | | | | | | | | | | | | | | | | | | | | | | | Introduce a new command "[no] allow-ecmp" to enable/disable the ECMP feature in RIPng. By default, ECMP is not allowed. Once ECMP is disabled, only one route entry can exist in the list. * ripng_zebra.c: adjust a debugging information, which shows the number of nexthops according to whether ECMP is enabled. * ripngd.c: ripng_ecmp_add() will reject the new route if ECMP is not allowed and some entry already exists. A new configurable command "allow-ecmp" is added to control whether ECMP is allowed. When ECMP is disabled, ripng_ecmp_disable() is called to remove the multiple nexthops. * ripngd.h: Add a new member "ecmp" to "struct ripng", indicating whether ECMP is allowed or not.

* ripngd: add ECMP supportFeng Lu2015-05-276-349/+459
| | | | | | | | | | | | | | | | | | | | | | | | * Each node in the routing table is changed into a list, holding the multiple equal-cost paths. * If one of the multiple entries gets less-preferred (greater metric or greater distance), it will be directly deleted instead of starting a garbage-collection timer for it. The garbage-collection timer is started only when the last entry in the list gets INFINITY. * Some new functions are used to maintain the ECMP list. And hence ripng_route_process(), ripng_redistribute_add() and ripng_timeout() are significantly simplified. * ripng_zebra_ipv6_add() and ripng_zebra_ipv6_delete() now can share the common code. The common part is moved to ripng_zebra_ipv6_send().

* build: add --enable-werrorDavid Lamparter2015-04-211-1/+1
| | | | | | | | | | | | | | | This allows enabling -Werror in a consistent way. Note that this is different from just specifiying it in CFLAGS, since that would either break configure tests (if done on ./configure), or would override configure's CFLAGS (if done on make). Using --enable-werror instead provides a new WERROR variable that is additionally used during make with a consistent set of warning flags. The tests/ directory is exempt.

* zebra, ripngd: remove ::/64 special-casingDavid Lamparter2015-02-141-18/+0
| | | | | | | | | | | | | | | | | In the 90ies, IPv4 was believed to exist within IPv6, with some kernels implementing this belief in code... Our code here is keyed to "#ifdef LINUX", yet no Linux from the past 10 years had this, making the code completely useless. FreeBSD 10.0 does in fact have a "::/96 via ::1 dev lo0 reject" route. IMHO we shouldn't mess with that, the admin can filter as neccessary anyway.

| | | | | | | | | | | | | | | | | | | | | IPv6 supports the same concept of differentiated service for routing protocols as IPv4, but like too many things, the standards committee decided that having two names for the same thing wasn't good enough and introduced a third more generic term transport class.
