2013-09-19zebra: implement NEXTHOP_FLAG_ONLINKChristian Franke
On Linux, the kernel will only allow for a route to be installed when its gateway is directly attached according the kernel fib. There are cases when this restriction by the kernel is too strong, in those cases, we deploy the RTNH_F_ONLINK netlink flag.

2013-09-19zebra: rework recursive route resolutionChristian Franke
Change the datastructure for recursive routes. This brings the following benefits: By using struct nexthop also to store nexthops obtained by recursive resolution, we can get rid of quite a bit of code duplication in the fib management. (rt_netlink, rt_socket, ...) With the new datastructure we can make use of all available paths when recursive routes are resolved with multipath routes.

2013-09-19zebra: improve interface shutdown behaviourChristian Franke
Linux removes IPv6 addresses when the interface is set down. Those addresses need to be readded when the interface is set up again. Also, an interface should not be reactivated from shutdown by configuring an ip address. Finally, remove the three-state logic for the shutdown setting as its sole current use may be mild confusion.

2013-09-19zebra: don't change connected state from zebra/interface.cChristian Franke
Try to avoid changing connected state from zebra/interface.c as this means making assumptions about kernel behaviour which may be or may become wrong. This state should rather be updated by events from the kernel. Signed-off-by: Christian Franke <chris@opensourcerouting.org> Signed-off-by: David Lamparter <equinox@opensourcerouting.org>
2013-09-19zebra: add ZEBRA_IFC_QUEUED to keep track of kernel stateChristian Franke
As there are timeframes when we don't get a notification from the kernel about new addresses. (e.g. while Linux performs IPv6 DAD), we need to have some information whether an address has been sent to the kernel or not. One case where this is relevant would be a user adding an IPv6 address, but deleting it before DAD has been complete. With the next patch which removes some (ill assuming) synchronous parts in address setup, ipv6_address_uninstall would not know whether or not it has to actually delete the prefix from the kernel. Resolving these windows where we lack information is what the flag ZEBRA_IFC_QUEUED is intended for.

2013-09-19zebra: warn if advertising connected with _REAL unsetChristian Franke
The implementation in zebra and the zclient protocol allow to communicate addresses to clients which are not yet in the kernel. This is usually not done and most clients seem to expect an address to be configured in the kernel when they receive it. Therefore, it seems reasonable to issue a warning when advertising an address to the clients that is not yet in the kernel.

2013-09-19zebra: process information about new addresses (BZ#486)Christian Franke
Because of a change of semantics in the Linux kernel, information about changes made by zebra itself was not considered for updates. This change should fix this by accounting for the new semantics.

2013-08-06bgpd, zebra: Support NEXTHOP_IPV4_IFINDEX in nexthop_lookup apiChristian Franke
Since commit ba281d3d040, ospfd uses NEXTHOP_IPV4_IFINDEX routes. The API between zebra and bgpd which is used to query nexthops for recursive routes did not support this nexthop type and therefore, ospf changes (or any other IGP changes which use NEXTHOP_IPV4_IFINDEX) would never trigger any recursive route update.

Not only was there a minor typo in the "pragma weak" preprocessor checks, but also were the tests not behaving as needed - they only indicated support for the /first/ method of implementing weak aliases, which on Linux is __attribute__ and not #pragma. * m4/ax_sys_weak_alias.m4: set defines for _all_ weak alias methods * zebra/kernel_null.c: fix typo Cc: Doug VanLeuven <roamdad@sonic.net> Signed-off-by: David Lamparter <equinox@opensourcerouting.org>
2013-01-16zebra: fix sockaddr_dl length assumptions (BZ#737)David Lamparter
Quagga makes bad assumptions about sockaddr_dl (on NetBSD, but possibly on other systems as well). Particularly, sizeof(struct sockaddr_dl) returns a size that does not include the full sdl_data field, leading to not enough data being copied. This breaks IPv6 RAs in particular, as a broken mac address from sockaddr_dl will be included in the packets.

2013-01-14zebra: don't overrun afi/safi array boundariesLeonid Rosenboim

Previously, on platforms with a page size greater than 8192, if you had added too many interfaces, zebra would not have enough buffer space to get the entire interface list.

2012-11-30zebra: add module to communicate routes to FPMAvneesh Sachdev
Enhance zebra to send routes to the (optional) Forwarding Path Manager component using the interface defined by fpm/fpm.h. * configure.ac - Add --enable-fpm flag. The FPM-related code in zebra is activated only if the build is configured with '--enable-fpm'. - Add HAVE_NETLINK automake conditional. This allows us to conditionally build netlink-dependent C code. * zebra/{rib.h,zebra_rib.c} - Add the 'fpm_q_entries' field to the rib_dest_t structure. This allows dests to be placed on the fpm queue. - Define a couple new rib_dest_t flags that hold FPM-related state. - Invoke the zfpm_trigger_update() function for a route_node whenever the information to be sent to the FPM changes. - rib_can_delete_dest(): Return FALSE if we have to update the FPM about the given dest. 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.

2012-11-30zebra: add way to determine VRF/AFI/SAFI of tableAvneesh Sachdev
Add some code that allows us to determine which VRF and AFI/SAFI a given RIB table corresponds to. * zebra/rib.h Add rib_table_info_t structure, which contains information about the VRF, AFI and SAFI that a table is for. * zebra/zebra_rib.c - Add the vrf_table_create() function, which creates a table and sets its 'info' pointer to a newly created rib_table_info_t. The 'info' pointer allows us to go from a route_node or a table to the associated vrf. - vrf_alloc(): Use vrf_create_table() to create tables. * lib/memtypes.c Add memory type for rib_table_info_t.

2012-11-30zebra: add structure to hold per-prefix state in RIBAvneesh Sachdev
Add the rib_dest_t structure to hold per-prefix state in the routing information base. This gives us an appropriate place to maintain the queueing state of a route_node. Queuing state was previously being stored on the first rib in the list of ribs hanging off the route_node. * zebra/rib.h - Add new structure rib_dest_t. - Remove the rn_status field from 'struct rib', it is no longer required. - Add macros (RNODE_FOREACH_RIB, RNODE_FOREACH_RIB_SAFE) for walking all 'struct ribs' corresponding to a route_node. These hide the fact that there is an intermediate rib_dest_t structure. - Add a few utility inlines to go between a rib_dest_t and associated structures. * zebra/zebra_rib.c - rib_link()/rib_unlink() Tweak for new behavior, where the 'info' pointer of a route_node points to a rib_dest_t. The list of ribs for a prefix now hangs off of the dest. Change the way we ref count route_nodes. We now hold a single ref count on a route_node if there is a corresponding rib_dest_t. - Maintain the queuing state of a route_node on the flags field of the rib_dest_t. - Add the rib_gc_dest() function, which deletes a rib_dest_t if it is no longer required. A rib_dest_t can be deleted iff there are no struct ribs hanging off of it. - Call rib_gc_dest() any time we unlink a rib from the rib_dest_t. Currently we only need to call it once, just before we return from rib_process(). * zebra/{redistribute,zebra_rib,zebra_snmp,zebra_vty}.c Use new macros to walk over route_node ribs. * lib/memtypes.c Add memory type for rib_dest_t.

2012-11-05zebra: kernel_socket: fix overflow in RTA_ADDR & RTA_ATTRDoug VanLeuven
In zebra/kernel_socket.c, copying sockaddr from *_msghdr: There are really 2 different lengths that need to be determined. 1) the length required to point to the next sockaddr in the mesg buffer which might include any required padding and 2) the actual length of the sockaddr data that needs to be copied into the destination field. They may or may not be the same value. Sizeof sockaddr_in6 is 28, which to pad for alignment purposes on 32 bit systems with a long of 4 bytes is evenly divided and requires no padding. On 64 bit systems, with a long of 8 it is padded with 4 extra bytes.So the current RTA_* macros are copying 32 bytes into a 28 byte field on 64 bitsystems, where the field overflow did not occur on the 32 bit systems. Since using sa_len required the use of an #ifdef which couldn't be used directly inside a #define, it made sense to move the copy into the function to allow typdef checking throughout and eliminate the hack to suppress compiler warnings. Fixed declaration of cp in ifm_read after compiler noticed type mismatch.

2012-06-25snmp: let handlers accept OID from a lesser prefixVincent Bernat
Most table handlers do not expect to be given an OID whose prefix is outside what they can handle.

2012-04-08zebra: include hardware addr in if up/down messagesJosh Bailey
Change interface up/down notification messages to also include the hardware address of the interface. The format of these messages is now identical to the interface add message -- move the serialization code to common functions. * lib/zclient.c: Modify zebra_interface_if_set_value() to also parse the hardware address. Invoke it from zebra_interface_add_read() and and zebra_interface_state_read(). * zebra/zserv.c: Add zserv_encode_interface(). Invoke it from zserv_interface_add(), zserv_interface_delete() and zserv_interface_update().
