* lib: fix vrf_bitmap leak in zclient_free()David Lamparter2016-03-081-0/+10
| | | | | | | | | zclient_stop(), which is used as antagonist to zclient_init(), needs to undo the vrf_bitmap allocation. Otherwise zclient_init() will leak the allocated memory, for example when zclient_reset() is used.

* lib: Check prefix length from zebra is sensiblePaul Jakma2016-03-081-17/+28
| | | | | | | | | | | | | * 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 can overflow (struct interface) hw_addr if zebra is evilPaul Jakma2016-03-081-1/+1
| | | | | | | | | | | | | | | * lib/zclient.c: (zebra_interface_if_set_value) The hw_addr_len field is used as trusted input to read off the hw_addr and write to the INTERFACE_HWADDR_MAX sized hw_addr field. The read from the stream is bounds-checked by the stream abstraction, however the write out to the heap can not be. Tighten the supplied length to stream_get used to do the write. Impact: a malicious zebra can overflow the heap of clients using the ZServ IPC. Note that zebra is already fairly trusted within Quagga. Reported-by: Kostya Kortchinsky <kostyak@google.com>

* lib, zebra: unify link layer type and hardware address handlingTimo Teräs2016-02-261-4/+1
| | | | | | | | | | | | | | | | This removes the BSD specific usage of struct sockaddr_dl hardware address. This unifies to use explict hw_addr member for the address, and zebra specific enumeration for the link layer type. Additionally the zapi is updated to never send platform specific structures over the wire, but the ll_type along with hw_addr_len and hw_addr are now sent for all platforms.

* *: add VRF ID in the API message headerFeng Lu2015-06-031-59/+92
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* lib: unset ZEBRA_IFA_PEER if no dst addr present (BZ#801)David Lamparter2014-08-181-0/+10
| | | | | | | | | | | | | | | | | | On OpenBSD, carp interfaces claim to be PtP interfaces with a 0.0.0.0/0 peer address. We process those in zebra and try to send them to clients, at which point they get encoded as all-0. The client code, however, decodes that to a NULL pointer instead of 0.0.0.0. This later turns into a SEGV when CONNECTED_PREFIX sees that ZEBRA_IFA_PEER is set and tries to access the peer prefix. This is a band-aid fix for stable/0.99.23, a long-term solution needs some conceptual improvements on the entire thing. (The usefulness of a PtP-to-0.0.0.0/0 is a separate question; at this point dropping the peer prefix seems the least intrusive solution.)

| | | | | | | | | | | | | 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.

These patches fix all of the numerous crashes, assertion failures, memory leaks and memory stomping I could find. Valgrind was used extensively. Added new function bgp_exit() to help catch problems. If "debug bgp" is configured and bgpd exits with status of 0, statistics on remaining lib/memory.c allocations are printed to stderr. It is my hope that other developers will use this to stay on top of memory issues. Example questionable exit: bgpd: memstats: Current memory utilization in module LIB: bgpd: memstats: Link List : 6 bgpd: memstats: Link Node : 5 bgpd: memstats: Hash : 8 bgpd: memstats: Hash Bucket : 2 bgpd: memstats: Hash Index : 8 bgpd: memstats: Work queue : 3 bgpd: memstats: Work queue item : 2 bgpd: memstats: Work queue name string : 3 bgpd: memstats: Current memory utilization in module BGP: bgpd: memstats: BGP instance : 1 bgpd: memstats: BGP peer : 1 bgpd: memstats: BGP peer hostname : 1 bgpd: memstats: BGP attribute : 1 bgpd: memstats: BGP extra attributes : 1 bgpd: memstats: BGP aspath : 1 bgpd: memstats: BGP aspath str : 1 bgpd: memstats: BGP table : 24 bgpd: memstats: BGP node : 1 bgpd: memstats: BGP route : 1 bgpd: memstats: BGP synchronise : 8 bgpd: memstats: BGP Process queue : 1 bgpd: memstats: BGP node clear queue : 1 bgpd: memstats: NOTE: If configuration exists, utilization may be expected. Example clean exit: bgpd: memstats: No remaining tracked memory utilization. This patch fixes bug #397: "Invalid free in bgp_announce_check()". This patch fixes bug #492: "SIGBUS in bgpd/bgp_route.c: bgp_clear_route_node()". My apologies for not separating out these changes into individual patches. The complexity of doing so boggled what is left of my brain. I hope this is all still useful to the community. This code has been production tested, in non-route-server-client mode, on a linux 32-bit box and a 64-bit box. Release/reset functions, used by bgp_exit(), added to: bgpd/bgp_attr.c,h bgpd/bgp_community.c,h bgpd/bgp_dump.c,h bgpd/bgp_ecommunity.c,h bgpd/bgp_filter.c,h bgpd/bgp_nexthop.c,h bgpd/bgp_route.c,h lib/routemap.c,h File by file analysis: * bgpd/bgp_aspath.c: Prevent re-use of ashash after it is released. * bgpd/bgp_attr.c: #if removed uncalled cluster_dup(). * bgpd/bgp_clist.c,h: Allow community_list_terminate() to be called from bgp_exit(). * bgpd/bgp_filter.c: Fix aslist->name use without allocation check, and also fix memory leak. * bgpd/bgp_main.c: Created bgp_exit() exit routine. This function frees allocations made as part of bgpd initialization and, to some extent, configuration. If "debug bgp" is configured, memory stats are printed as described above. * bgpd/bgp_nexthop.c: zclient_new() already allocates stream for ibuf/obuf, so bgp_scan_init() shouldn't do it too.

Use struct bgp_clear_node_queue to supply data to worker. Add call to bgp_table_lock(). - bgp_clear_route(): Add support for BGP_CLEAR_ROUTE_NORMAL or BGP_CLEAR_ROUTE_MY_RSCLIENT. - bgp_clear_route_all(): Use BGP_CLEAR_ROUTE_NORMAL. Bug 397 fixes: - bgp_default_originate() - bgp_announce_table() * bgpd/bgp_table.h: - struct bgp_table: Added reference count. Changed type of owner to be "struct peer *" rather than "void *". - struct bgp_node: Correct reference counter "lock" to be signed. * bgpd/bgp_table.c: - Added bgp_table reference counting. - bgp_table_free(): Fixed cleanup code. Call peer_unlock() on owner if set. - bgp_unlock_node(): Added assertion. - bgp_node_get(): Added call to bgp_lock_node() to code path that it was missing from. * bgpd/bgp_vty.c: - peer_rsclient_set_vty(): Call peer_lock() as part of peer assignment to owner. Handle failure gracefully. - peer_rsclient_unset_vty(): Add call to bgp_clear_route() with BGP_CLEAR_ROUTE_MY_RSCLIENT purpose. * bgpd/bgp_zebra.c: Made it so zclient is global so bgp_exit() can use it. * bgpd/bgpd.c: - peer_lock(): Allow to be called when status is "Deleted". - peer_deactivate(): Supply BGP_CLEAR_ROUTE_NORMAL purpose to bgp_clear_route() call. - peer_delete(): Common variable listnode pn. Fix bug in which rsclient was only dealt with if not part of a peer group. Call bgp_clear_route() for rsclient, if appropriate, and do so with BGP_CLEAR_ROUTE_MY_RSCLIENT purpose. - peer_group_get(): Use XSTRDUP() instead of strdup() for conf->host. - peer_group_bind(): Call bgp_clear_route() for rsclient, and do so with BGP_CLEAR_ROUTE_MY_RSCLIENT purpose. - bgp_create(): Use XSTRDUP() instead of strdup() for peer_self->host. - bgp_delete(): Delete peers before groups, rather than after. And then rather than deleting rsclients, verify that there are none at this point. - bgp_unlock(): Add assertion. - bgp_free(): Call bgp_table_finish() rather than doing XFREE() itself. * lib/command.c,h: Compiler warning fixes.

(bug #363) Should check for in_pktinfo for IRDP 2006-05-27 Paul Jakma <paul.jakma@sun.com> * configure.ac: General cleanup of header and type checks, introducing an internal define, QUAGGA_INCLUDES, to build up a list of stuff to include so as to avoid 'present but cant be compiled' warnings. Misc additional checks of things missing according to autoscan. Add LIBM, for bgpd's use of libm, so as to avoid burdening LIBS, and all the binaries, with libm linkage. Remove the bad practice of using m4 changequote(), just quote the []'s in the case statements properly. This should fix bugs 162, 303 and 178. * */*.{c,h}: Update all HAVE_* to the standard autoconf namespaced HAVE_* defines. I.e. HAVE_SA_LEN -> HAVE_STRUCT_SOCKADDR_SA_LEN, * bgpd/Makefile.am: Add LIBM to bgpd's LDADD, for pow().

Schorr <ajschorr@alumni.princeton.edu> * if.h: (struct connected) Add new ZEBRA_IFA_PEER flag indicating whether a peer address has been configured. Comment now shows the new interpretation of the destination addr: if ZEBRA_IFA_PEER is set, then it must contain the destination address, otherwise it may contain the broadcast address or be NULL. (CONNECTED_DEST_HOST,CONNECTED_POINTOPOINT_HOST) Remove obsolete macros that were specific to IPv4 and not fully general. (CONNECTED_PEER) New macro to check ZEBRA_IFA_PEER flag. (CONNECTED_PREFIX) New macro giving the prefix to insert into the RIB: if CONNECTED_PEER, then use the destination (peer) address, else use the address field. (CONNECTED_ID) New macro to come up with an identifying address for the struct connected. * if.c: (if_lookup_address, connected_lookup_address) Streamline logic with new CONNECTED_PREFIX macro. * prefix.h: (PREFIX_COPY_IPV4, PREFIX_COPY_IPV6) New macros for better performance than the general prefix_copy function. * zclient.c: (zebra_interface_address_read) For non-null destination addresses, set prefixlen to equal the address prefixlen. This is needed to get the new CONNECTED_PREFIX macro to work properly. * connected.c: (connected_up_ipv4, connected_down_ipv4, connected_up_ipv6, connected_down_ipv6) Simplify logic using the new CONNECTED_PREFIX macro. (connected_add_ipv4) Set prefixlen in destination addresses (required by the CONNECTED_PREFIX macro). Use CONNECTED_PEER macro instead of testing for IFF_POINTOPOINT. Delete invalid warning message. Warn about cases where the ZEBRA_IFA_PEER is set but no destination address has been supplied (and turn off the flag). (connected_add_ipv6) Add new flags argument so callers may set the ZEBRA_IFA_PEER flag. If peer/broadcast address satisfies IN6_IS_ADDR_UNSPECIFIED, then reject it with a warning. Set prefixlen in destination address so CONNECTED_PREFIX will work. * connected.h: (connected_add_ipv6) Add new flags argument so callers may set the ZEBRA_IFA_PEER flag. * interface.c: (connected_dump_vty) Use CONNECTED_PEER macro to decide whether the destination address is a peer or broadcast address (instead of checking IFF_BROADCAST and IFF_POINTOPOINT). * if_ioctl.c: (if_getaddrs) Instead of setting a peer address only when the IFF_POINTOPOINT is set, we now accept a peer address whenever it is available and not the same as the local address. Otherwise (no peer address assigned), we check for a broadcast address (regardless of the IFF_BROADCAST flag). And must now pass a flags value of ZEBRA_IFA_PEER to connected_add_ipv4 when a peer address is assigned. The same new logic is used with the IPv6 code as well (and we pass the new flags argument to connected_add_ipv6). (if_get_addr) Do not bother to check IFF_POINTOPOINT: just issue the SIOCGIFDSTADDR ioctl and see if we get back a peer address not matching the local address (and set the ZEBRA_IFA_PEER in that case). If there's no peer address, try to grab SIOCGIFBRDADDR regardless of whether IFF_BROADCAST is set. * if_ioctl_solaris.c: (if_get_addr) Just try the SIOCGLIFDSTADDR ioctl without bothering to check the IFF_POINTOPOINT flag. And if no peer address was found, just try the SIOCGLIFBRDADDR ioctl without checking the IFF_BROADCAST flag. Call connected_add_ipv4 and connected_add_ipv6 with appropriate flags. * if_proc.c: (ifaddr_proc_ipv6) Must pass new flags argument to connected_add_ipv6. * kernel_socket.c: (ifam_read) Must pass new flags argument to connected_add_ipv6. * rt_netlink.c: (netlink_interface_addr) Copy logic from iproute2 to determine local and possible peer address (so there's no longer a test for IFF_POINTOPOINT). Set ZEBRA_IFA_PEER flag appropriately. Pass new flags argument to connected_add_ipv6. (netlink_address) Test !CONNECTED_PEER instead of if_is_broadcast to determine whether the connected destination address is a broadcast address. * bgp_nexthop.c: (bgp_connected_add, bgp_connected_delete) Simplify logic by using new CONNECTED_PREFIX macro. * ospf_interface.c: (ospf_if_is_configured, ospf_if_lookup_by_prefix, ospf_if_lookup_recv_if) Simplify logic using new CONNECTED_PREFIX macro. * ospf_lsa.c: (lsa_link_ptop_set) Using the new CONNECTED_PREFIX macro, both options collapse into the same code. * ospf_snmp.c: (ospf_snmp_if_update) Simplify logic using new CONNECTED_ID macro. (ospf_snmp_is_if_have_addr) Simplify logic using new CONNECTED_PREFIX macro. * ospf_vty.c: (show_ip_ospf_interface_sub) Use new CONNECTED_PEER macro instead of testing the IFF_POINTOPOINT flag. * ospfd.c: (ospf_network_match_iface) Use new CONNECTED_PEER macro instead of testing with if_is_pointopoint. And add commented-out code to implement alternative (in my opinion) more elegant behavior that has no special-case treatment for PtP addresses. (ospf_network_run) Use new CONNECTED_ID macro to simplify logic. * rip_interface.c: (rip_interface_multicast_set) Use new CONNECTED_ID macro to simplify logic. (rip_request_interface_send) Fix minor bug: ipv4_broadcast_addr does not give a useful result if prefixlen is 32 (we require a peer address in such cases). * ripd.c: (rip_update_interface) Fix same bug as above.
* [lib/zclient] Export zclient_create_headerpaul2006-01-171-1/+1
| | | | | | | 2006-01-17 Paul Jakma <paul.jakma@sun.com> * zclient.{c,h}: (zclient_create_header) export this, seems others could use it (in lieu of more complete zserv helpers).
* [zserv] Extend Zserv header with version information and marker fieldpaul2006-01-161-23/+36
| | | | | | | | | | | | | 2006-01-16 Paul Jakma <paul.jakma@sun.com> * lib/zclient.h: Update the Zserv protocol header with a version field. Define the old command field to be a 'marker', to allow old Zserv and updated Zserv to be differentiated. Future updates will bump the version field obviously. New command field is made wider. Try to stop using the 'zebra_size_t' typedef in the callbacks. * lib/zclient.c: Update to read/write new format header. * zebra/zserv.c: Ditto
* [zserv] Update interface flags to 8 bytes wide.paul2006-01-111-3/+4
| | | | | | | | | | | | | | 2006-01-11 Paul Jakma <paul.jakma@sun.com> * if.h: (struct interface) expand flags to 8 bytes. * zclient.c: (zebra_interface_{add,state}_read) stream read of interface flags now need to use stream_getq. (zebra_interface_if_set_value) ditto 2006-01-11 Paul Jakma <paul.jakma@sun.com> * zserv.c: (zsend_interface_{add,delete,update}) if flags are 8 bytes now, update to write out with stream_putq.

| | | | | | | | | | | | | | | | | | | | | | | | | | * (general) extern and static'ification of functions in code and header. Cleanup any definitions with unspecified arguments. Add casts for callback assignments where the callback is defined, typically, as passing void *, but the function being assigned has some other pointer type defined as its argument, as gcc complains about casts from void * to X* via function arguments. Fix some old K&R style function argument definitions. Add noreturn gcc attribute to some functions, as appropriate. Add unused gcc attribute to some functions (eg ones meant to help while debugging) Add guard defines to headers which were missing them. * command.c: (install_node) add const qualifier, still doesnt shut up the warning though, because of the double pointer. (cmp_node) ditto * keychain.c: (key_str2time) Add GET_LONG_RANGE() macro, derived fromn vty.h ones to fix some of the (long) < 0 warnings. * thread.c: (various) use thread_empty (cpu_record_hash_key) should cast to uintptr_t, a stdint.h type * vty.h: Add VTY_GET_IPV4_ADDRESS and VTY_GET_IPV4_PREFIX so they removed from ospfd/ospf_vty.h * zebra.h: Move definition of ZEBRA_PORT to here, to remove dependence of lib on zebra/zserv.h

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Implement non-blocking zclient I/O with buffering. * zclient.h (struct zclient): Add two fields to support non-blocking I/O: struct buffer *wb, and struct thread *t_write. (zclient_free): Remove function. (zebra_redistribute_send): Change 2nd arg from socket fd to struct zclient * (needed to support non-blocking I/O and buffering). (zclient_send_message): New function to send an arbitrary message with non-blocking I/O. * zclient.c (zclient_new): Create write buffer. (zclient_free): Remove unused function. (zclient_stop): Must cancel new t_write thread. Also, reset all buffers: ibuf, obuf, and wb. (zclient_failed): New helper function for typical error handling. (zclient_flush_data): New thread to flush queued data. (zclient_send_message): New function to send the message in zclient->obuf to zebra using non-blocking I/O and buffering. (zebra_message_send, zapi_ipv4_route, zapi_ipv6_route): Use new zclient_send_message function instead of calling writen. (zclient_start): Set socket non-blocking. Also, change 2nd arg to zebra_redistribute_send from zclient->sock to zclient. (zebra_redistribute_send): Change 2nd arg to struct zclient *. Can now use zclient->obuf to assemble the message instead of allocating a temporary stream. And call zclient_send_message to send the message instead of writen. (zclient_read): Convert to support non-blocking I/O by using stream_read_try instead of deprecated stream_read. (zclient_redistribute): Change 2nd arg to zebra_redistribute_send from zclient->sock to zclient. * ospf6_zebra.c (ospf6_zebra_redistribute, ospf6_zebra_no_redistribute): Change 2nd arg to zebra_redistribute_send from zclient->sock to zclient. * ospf_zebra.c (ospf_zebra_add): Call zclient_send_message instead of writen. * rip_zebra.c (rip_redistribute_set, rip_redistribute_unset, rip_redistribute_clean): Change 2nd arg to zebra_redistribute_send from zclient->sock to zclient. * ripng_zebra.c (ripng_redistribute_unset, ripng_redistribute_clean): Change 2nd arg to zebra_redistribute_send from zclient->sock to zclient. * bgp_zebra.c (bgp_redistribute_set, bgp_redistribute_unset): The 2nd arg to zebra_redistribute_send is now zclient instead of zclient->sock. * isis_zebra.h (isis_zebra_finish): Remove declaration of unused function. * isis_zebra.c (isis_zebra_route_add_ipv4): Call zclient_send_message to send the message to zebra instead of calling writen directly, since zclient_send_message understands non-blocking I/O and will manage the buffer queue appropriately. (isis_zebra_finish): Remove unused function, particularly since the zclient_free function has been removed.
