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.

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.

LLVM clang does not support #pragma weak (bug 3679) on OS X. There are other systems where the #pragma weak has varying syntax. Added m4 file from the autoconf archives: http://www.gnu.org/software/autoconf-archive/ax_sys_weak_alias.html Fix up zebra/*_null.c files to use #pragma weak alias or stub functions if not available. It's incomplete in that the different format #pragma enable easier fixes on need. Tested on 64bit OS X 10.7, FreeBSD 9.0 amd64 & i386 (32bit) using gcc & clang. Tested on linux 64bit.

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.

2012-11-05build: check actually-used BSD link state fieldsDoug VanLeuven
ifi_link_state missing in OS X. There could be other *BSD's that haven't implemented it and possibly affects older implementations. The existing HAVE_BSD_LINK_DETECT configure.ac check is only confirming the link state detection using ifmediareq.ifm_status found in <net/if_media.h>. This is the link state detection used in zebra/ioctl.c. Later, *BSD redefined struct if_data in <net/if.h> and included link state detection. This is the method used in zebra/kernel_socket.c Additional test defined in config.ac to test for member struct if_data.ifi_link_state defined in <net/if.h> separate from test for <net/if_media.h> ifmediareq.ifm_status Fixed #ifdef's in zebra/kernel_socket.c to use the new #define No impact on older function calls in zebra/ioctl.c Tested on 64bit OS X 10.7, FreeBSD 9.0 amd64 & i386 (32bit) using gcc & clang.

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.

In OS X 10.7 zebra crashed on invalid execution address. sockaddr padding in *_msghdr is observed to be 4 bytes in 64bit OS X. The ROUNDUP macro assumed alignment on sizeof(long) which allocates 8 bytes on 64bit systems, 4 bytes on 32bit systems which is true for BSD generally. Test for Apple and use sizeof(int) which allocates 4 bytes on 32 & 64bit systems.

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. This is not a problem with the SMUX implementation since it always correct the OID such that the prefix matches. However, this is not the case for the AgentX implementation. A new function, smux_header_table() is used to do this normalization.
2012-06-25build: use net-snmp-config to configure NetSNMPVincent Bernat
The correct method to link to NetSNMP is to use net-snmp-config (which is like pkg-config).

2012-01-26zebra: justify some IPv6 ND RA timers wrt RFCDenis Ovsienko
There was a regression introduced with the previous commit: "ipv6 nd home-agent-lifetime 1800000" appeared by default in every interface section of running-config, although this command is invalid in this context. Troubleshooting and bugfixing of the issue tracked out several bugs in router advertisement procedures, some of which are fixed in this commit. * zebra/interface.c * if_zebra_new_hook(): update to treat -1 as "uninitialized" * nd_dump_vty(): idem * zebra/rtadv.c * rtadv_send_packet(): update processing of "router lifetime" field, "home agent" option and "home agent lifetime" field to conform to RFC6275 better * ipv6_nd_ra_interval_msec(): update MaxRtrAdvInterval range check, make sure it never exceeds (initialized) AdvDefaultLifetime * ipv6_nd_ra_interval(): idem * ipv6_nd_ra_lifetime(): update AdvDefaultLifetime range check, make sure it never falls below MaxRtrAdvInterval * ipv6_nd_homeagent_lifetime(): update HomeAgentLifetime range check * no_ipv6_nd_ra_lifetime(): update to treat -1 as "uninitialized" * no_ipv6_nd_homeagent_lifetime(): idem * rtadv_config_write(): idem
