* zebra: atomic FIB updatesTimo Teräs2015-06-041-4/+4
| | | | | | | | | | | This commit updates the kernel API so that route changes are atomically updated using change/replaces messages instead of first sending a withdraw followed with update. Same for zclient updates, changes are sent as single ADD instead of DELETE + ADD. Signed-off-by: Timo Teräs <timo.teras@iki.fi>

| * zebra: static int inline -> static inline intDavid Lamparter2015-04-211-2/+2
| | | | | | | | | | | | | | The BSD socket kernel interface had some weird ordering of function attribute keywords. ("static int inline foobar()") Signed-off-by: David Lamparter <equinox@opensourcerouting.org>
| * zebra: use SA_SIZE for RT_ROUNDUP on FreeBSDDavid Lamparter2015-04-211-10/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | FreeBSD provides SA_SIZE (and none of the other options to infer padded size of a struct sockaddr). Just define SAROUNDUP to SA_SIZE if it is available. This also drops a superfluous-looking extra macro branch which would require ROUNDUP. It seemed redundant to my eyes, but I have no idea what odd things might have triggered addition of this in the first place... Signed-off-by: David Lamparter <equinox@opensourcerouting.org>
* | Fix alignment assumptions on non-RT_ROUNDUP platforms.Greg Troxel2015-03-231-2/+2
|/ | | | | | | The comment said that apple uses int and BSD traditionally used long, but the code was backwards. This fixes apple to be int, and otherwise long. That should make FreeBSD, which aligns to long, work correctly, even without using SA_SIZE.
* zebra/kernel_socket.c: Use platform alignmentGreg Troxel2014-12-021-10/+40
| | | | | | | | | Use the platform-provided RT_ROUNDUP macro to align sockaddrs on the routing socket, rather than using hard-coded assumptions about alignment. Emit a warning if the OS doesn't define alignment macros. Resolves failure of ripngd on NetBSD 6 i386, which changed alignment to uint64_t from long.
* *: nuke ^L (page feed)David Lamparter2014-06-041-4/+4
| | | | | | | | | | | | | | Quagga sources have inherited a slew of Page Feed (^L, \xC) characters from ancient history. Among other things, these break patchwork's XML-RPC API because \xC is not a valid character in XML documents. Nuke them from high orbit. Patches can be adapted simply by: sed -e 's%^L%%' -i filename.patch (you can type page feeds in some environments with Ctrl-V Ctrl-L) Signed-off-by: David Lamparter <equinox@opensourcerouting.org>
* ospf6d: solve segfaults with ospf6d on FreeBSDIngo Flaschberger2014-03-211-0/+1
| | | | | | | | Do not send ospf6d hellos on fresh created interfaces without configuration (ie. no vlan configured). Ospf6d use ip6_mtu, if it's not initalised, Ospf6d tries to alloc indefinite size of memory. Signed-off-by: David Lamparter <equinox@opensourcerouting.org>
* zebra: fix sockaddr_dl length assumptions (BZ#737)David Lamparter2013-01-161-3/+12
| | | | | | | | | | | | | 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.

* build: check actually-used BSD link state fieldsDoug VanLeuven2012-11-051-6/+6
| | | | | | | | | | | | | | | | | | | | | | | | 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.

* zebra: kernel_socket: fix overflow in RTA_ADDR & RTA_ATTRDoug VanLeuven2012-11-051-9/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* zebra: kernel_socket: fix 64bit MacOS X alignmentDoug VanLeuven2012-11-051-0/+6
| | | | | | | | | | | | | | | | | | 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. Tested on 64bit OS X 10.7, FreeBSD 9.0 amd64 & i386 (32bit) using gcc & clang Signed-off-by: David Lamparter <equinox@opensourcerouting.org>

* zebra: set the interface link-layer socket addressTom Goff2011-12-131-0/+12
| | | | | | | | | * kernel_socket.c: (ifm_read) The reorganization from commit 6fe70d1b35c189cb1e488b2c26551ba7baac6148 removed setting the interface link-layer socket address structure on routing socket platforms. This restores saving the link-layer information because it might be used elsewhere: rtm_write() when no gateway is given, if_dump_vty() and rtadv_send_packet().

(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().

* [PtP over ethernet] New peer flag allows much more addressing flexibilityAndrew J. Schorr2006-12-121-1/+1

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.

The IFF_UP mangling for solaris was incomplete on the PF_ROUTE side. fix it. This changeset generally uglifies things. For some future work I'd like to see the state changes seperated out from the details of the code. Differences between systems might then be slightly easier to implement without convoluted hacks. Changes should be specific to Solaris mostly, however also tested on FreeBSD 6. * if_ioctl_solaris.c: (interface_list_ioctl) ignore ~IFF_UP interfaces, we'll hear about them when/if interface goes up through NEWADDR. Update flags explicitely at end of it to kick mangling. * ioctl_solaris.c: (if_mangle_up) removed to interface.c, in kind. (lifreq_set_name) more convenient to take the string, than the ifp. (if_get_flags_direct) new convenience function, returns the actual flags. Used during bootstrap in if_ioctl_solaris.c to peek at flags of logical interfaces to see whether or not to ignore them. (if_get_flags) ENXIO means it's gone, poke out IFF_UP and kick flags update. (if_{un,}set_flags) flags argument should be 64bit. * ioctl.{c,h}: flags argument should be 64bit. * interface.h: Add a 'primary_state' flag to struct zebra_if on SUNOS_5. Export if_flags_update. * interface.c: (if_flags_mangle) moved over in kind from ioctl_solaris.c. Nasty kludge to try get IFF_UP right, as much as is possible. Also keep track of the actual IFF_UP value for the primary interface, so we can know when the ifp must be deleted. (if_flags_update) Take a new interface flags value, apply it to the interface, and take whatever actions are required due to flag transitions. (if_refresh) flag state change logic is moved out to previous. Just call if_get_flags, which will end up using previous to effect the update of flags. (if_flag_dump_vty) IFF_IPV{4,6} aren't interesting, VIRTUAL and NOXMIT are though. * kernel_socket.c: (ifm_read) Down->Down transitions shouldn't create ifp, for non-IFANNOUNCE systems. Use if_flags_update to update flags. flag transition logic is now handled automatically through if_flags_update. (ifam_read) Better to call if_refresh *after* adding connected addresses, as connected count affects IFF_UP on IFF_UP-mangled systems. On Solaris, Up->Down due to DELADDR means we need to delete the ifp - the IFINFO might already have been and gone. * rt.h: include other dependent headers.

(ifm_read,ifam_read,rtm_read_mesg,kernel_read) Make static (ifam_read_mesg) make static. fix incorrect variable name. (rtm_read) make static. Fix call to rib_delete_ipv4 which should be rib_delete_ipv6. (routing_socket,kernel_init) should be static. Void argument should be specified as such, not left incomplete. * rt_netlink.c: rt.h should be included, contains prototypes of exported functions. (kernel_delete_ipv6_old) fix sign of index argument. * rt_socket.c: Exact same as previous. Also, make various functions static. * rtread_getmsg.c: Include zserv.h, which prototypes route_read. Make static. * rtread_sysctl.c: zserv.h and rt.h should be included. fix definition of route_read.
* [solaris] Extra debug and cross-checks for kernel_socket, two Sol9 fixes.paul2005-11-121-91/+151
| | | | | | | | | | | | | | | | | | | | | | | | | | 2005-11-12 Alexander Gall <gall@switch.ch> * See [quagga-dev 1815] * kernel_socket.c: (rtm_write) Use SAROUNDUP when HAVE_SIN_LEN is not available. * rt_socket.c: (kernel_rtm_ipv6(_multipath)) set family to AF_INET6 on ipv6 routes. 2005-11-12 Paul Jakma <paul.jakma@sun.com> * kernel_socket.c: Add RTA_NAME_GET macro to extract name from sockaddr_dl. Add some more RTF_ flags. * (ifan_read) Add some debug messages. * (ifm_read) Add more debug messages. More robust cross-checks of index against name. Fall back to by-name lookup if the index lookup fails, future proofing more than anything else. (ifam_read_mesg) Read RTA_IFP. Add debug messages. (ifam_read) More debug. If there's an RTA_IFP and it isn't the name of the interface, save it as the label. (rtm_read_mesg) Read RTA_IFP. (rtm_read) allow name to be retrieved. (rtmsg_debug) expand on the debug message.
* [zebra] Fix warning and small connected-label changes merge error.paul2005-11-111-5/+3
| | | | | | | | | | 2005-11-11 Paul Jakma <paul.jakma@sun.com> * kernel_socket.c: (ifm_read) arithmetic on void pointer warning. (ifam_read) Fix error from connected-with-label merge, something crept in from the pending Solaris kernel_socket.c patch which shouldn't have.
* 2005-11-03 Paul Jakma <paul.jakma@sun.com>paul2005-11-031-6/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * connected.{c,h}: Include memory.h (connected_add_ipv4) Use MTYPE for ifc label. (connected_add_ipv6) Also should accept label. Store it in ifp. (connected_del_ipv4) Taking label as argument is pointless. * rt_netlink.c: (netlink_interface_addr) update label usage for connected_{add,delete} functions. * if_ioctl.c: (if_getaddrs) NULL label for connected_add_ipv6. * if_ioctl_solaris.c: (interface_list_ioctl) Pass LIFC_NOXMIT so we also find out about NOXMIT interfaces like VNI. Bit of hackery to turn interface names into the primary interface name, later with routing socket messages we only will about primary interfaces anyway, so we must normalise the name. (if_get_addr) take label as argument, so it can be passed to connected_add. If label is provided, then it is interface name to issue the ioctl for address information on, not the ifp name. (interface_list) List AF_UNSPEC too, just in case. * if_proc.c: (ifaddr_proc_ipv6) label for connected_add_ipv6. * interface.c: (if_addr_wakeup) Some very bogus code - sets IFF_RUNNING - add comment. (if_refresh) (ip_address_install) Use MTYPE for ifc label. * ioctl_solaris.c: (if_mangle_up) New function. Hackery to make IFF_UP reflect whether any addresses are left on the interface, as we get signalled for IFF_UP flags change on the primary interface only. Logical interfaces dont generate IFINFO, but we do get an RTM_DELADDR. (if_get_flags) Call if_mangle_up before return. * kernel_socket.c: (ifam_read) Fixup calls to connected_{add,delete} to match above changes. Rename gate variable to brd, less confusing. Pass the interface name as a label, if it is not same name as ifp->name.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | * (general) RTM_CHANGE and implicit withdraw on RTM_NEWADDR support. * connected.c: (connected_withdraw) new function. withdraw a connected subnet address set from zebra, and pass information along to clients. (connected_announce) similar, but to announce a new connected subnet address set. (connected_check_ipv4) renamed to connected_check, as its AFI independent. (connected_add_ipv{4,6}) Remove the connected address announce stuff, use connected_announce instead. If connected_check indicates address is already present, treat it as an implicit withdraw of the existing address, ie remove the old address details and replace with the new details. (connected_delete_ipv{4,6}) Use connected_withdraw. (connected_check_ipv6) deleted in favour of connected_check. * connected.h: Rename connected_check_ipv4 to connected_check. delete connected_check_ipv6. * interface.c: Use connected_check rather than the AFI specific symbols. * kernel_socket.c: (rtm_read) RTM_CHANGE support. Create a rib delete event for the existing route, before adding route again. (kernel_read) we can handle RTM_CHANGE now.
* * zebra_rib.c, rib.h: Add distance and metric arguments to thehasso2005-08-271-1/+1
| | | | | | | | | | rib_add_ipv6() function so that IPv6 routes in RIB can have correct metric. No IPv6 routing daemon uses distance yet though. * zserv.c, connected.c, kernel_socket.c, rt_netlink.c, rtread_proc.c,zserv.c: Pass metric and distance info to the rib_add_ipv6(). Forwardport from stable branch.

| | | | | | | | | | | | | | | | | | | | * interface.c: (if_delete_update) should always be available, not just on RTM_IFANNOUNCE/NETLINK systems. * kernel_socket.c: (ifan_read) only call if_delete_update when interface departs, dont if_delete, because we wish to retain interface configuration state even when interfaces are removed. (ifm_read) If we dont have RTM_IFANNOUNCE, then transitioning to down state is only chance we have to clean up interface in case it is deleted (eg Solaris down -> unplumb -> plumb up). * redistribute.c: (zebra_interface_delete_update) should always be available, we /will/ call it now on all systems, via if_delete_update. * zserv.c: (zsend_interface_delete) ditto (zsend_interface_address) Update the call-flow diagramme, to reflect that if_delete_update /is/ now called on all systems, potentially. * zserv.h: (zsend_interface_delete) unconditionally exported, as above.
* 2005-06-28 Paul Jakma <paul.jakma@sun.com>paul2005-06-281-2/+2
| | | | | * kernel_socket.c: (RTA_{ADDR,ATTR}_GET) fix mistake, NULL check should be on DEST argument
* 2005-06-14 Paul Jakma <paul.jakma@sun.com>paul2005-06-141-52/+36
| | | | | | | | | | * kernel_socket.c: consolidate the IFAM{ADDR,MASK}GET and RTM{ADDR,MASK}GET macros into generic rta_addrs macros, RTA_{ADDR,ATTR}_GET. (af_check) could use 'inline' attribute (ifam_read_mesg) remove IFAM{ADDR,MASK}GET macro, change to generic macro. (rtm_read_mesg) similar
* 2005-04-02 Andrew J. Schorr <ajschorr@alumni.princeton.edu>ajs2005-04-031-1/+3
| | | | | | | | | | | * if_ioctl.c: (interface_list_ioctl) Use if_get_by_name_len. * if_proc.c: (ifaddr_proc_ipv6) Increase size of ifname buffer to avoid overflow. * kernel_socket.c: (ifan_read) Use if_get_by_name_len. * if.h: Fix comments to reflect that if_lookup_by_name and if_get_by_name now require the argument strings to be NUL-terminated. * if.c: (if_lookup_by_name) Compare using strcmp. (if_get_by_name) Pass strlen(ifname) as 2nd arg to if_create.
