2006-01-30[zebra] Fix pauls zebra_rib/rib_process commit mistakes, again.paul
2006-01-30 Paul Jakma <paul.jakma@sun.com> * zebra_rib.c: (rib_process) Fourth time lucky on this jinxed commit, last commit had a hole that could allow connected route selection to escape beyond the connected route logic. This time I cross-checked with Gunnar first. ;)
2006-01-25[zebra] Fix incorrect changes made in RIB metric selection patchpaul
2006-01-25 Gunnar Stigen <gunnar.stigen@axxessit.no> * zebra_rib.c: (rib_process) Application of Gunnar's earlier metric selection RIB change included incorrect tidy-ups made by commiter. Fix. (NB: any errors here are again due to paul).
2006-01-25[zebra/solaris] Interface state fixups for Solaris.paul
2006-01-25 Paul Jakma <paul.jakma@sun.com> * (general) More solaris PF_ROUTE hacks. 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.
2006-01-19[compiler] miscellaneous trivial compiler warning fixespaul
2006-01-19 Paul Jakma <paul.jakma@sun.com> * (general) various miscellaneous compiler warning fixes. Remove redundant break statements from switch clauses which return. return from main, not exit, cause it annoys SOS. Remove stray semi-colons which cause empty-statement warnings. * zebra/main.c: (sighup) remove private declaration of external function.
2006-01-182006-01-18 Gunnar Stigen <gunnar.stigen@axxessit.no>paul
* zebra_rib.c: Take interface metric into account.
2006-01-17[zebra] Record NEWADDR metric on PF_ROUTE, print CACHEINFO debug on netlinkpaul
2006-01-17 Paul Jakma <paul.jakma@sun.com> * kernel_socket.c: (ifam_read) Read metric from RTM_NEWADDR. If interface is an alias, pass the alias as a label for connected_add_ipv{4,6}. * rt_netlink.c: (netlink_interface_addr) print out IFA_CACHEINFO info, if present, when debugging kernel messages.
2006-01-17[zebra] Defensive if_getaddrs bug fix.paul
2006-01-17 Gunnar Stigen <gunnar.stigen@axxessit.no> * if_ioctl.c: (if_getaddrs) Be defensive about assuming that struct ifaddrs will have ifa_addr filled in.
2006-01-17[zebra] Include metric on connected routes.paul
2006-01-17 Gunnar Stigen <gunnar.stigen@axxessit.no> * connected.c: (connected_up_ipv{4,6}) Include interface metric on connected routes.
2006-01-16[zserv] Extend Zserv header with version information and marker fieldpaul
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
2006-01-11[zserv] Update interface flags to 8 bytes wide.paul
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.
2005-12-29remove dead code (from David Young)gdt
2005-12-292005-12-29 Greg Troxel <gdt@fnord.ir.bbn.com>gdt
* rt_socket.c (kernel_rtm_ipv4): Use AF_INET rather than AF_UNSPEC for mask. From David Young.
2005-11-26[zebra] fix connected_add_ipv6 declarations, label should be const.paul
2005-11-26 Paul Jakma <paul.jakma@sun.com> * connected.{c,h}: (connected_add_ipv6) label should have const qualifier, fix declarations.
2005-11-24[zebra] Fix mistake in previous commit and further compile warnings/errors.paul
2005-11-24 Paul Jakma <paul.jakma@sun.com> * kernel_socket.h: New header for functions exported to sysctl methods. * kernel_socket.c: include previous. Remove static qualifier from couple of functions which are used by sysctl methods, incorrectly added in previous commit. Add a workaround for a bogus gcc warning to the RTA_ macros. * Makefile.am: Add kernel_socket.h to noinst_HEADERS * if_sysctl.c: include rt.h and kernel_socket.h and remove redundant prototypes. * rtread_sysctl.c: ditto. (route_read) fix mismatch of return values. * {rt,zserv,rib}.h: Include lib headers depended on.
2005-11-23[zebra] fix some small compile errors, mark several functions staticpaul
2005-11-23 Paul Jakma <paul.jakma@sun.com> * (general) fix some small compile errors, and mark several functions as static. * kernel_socket.c: (ifan_read) should be static. fix missing brackets. (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.
2005-11-142005-11-14 Paul Jakma <paul.jakma@sun.com>paul
* zebra_rib.c: (rib_process) convert to new workqueue specs and shut up gcc, which complains about cast from void via function parameters, for some dumb reason. Do the cast inside the function instead. (rib_queue_qnode_del) ditto. (rib_queue_init) no need for the casts anymore.
2005-11-12[solaris] Extra debug and cross-checks for kernel_socket, two Sol9 fixes.paul
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.
2005-11-11[zebra] Fix warning and small connected-label changes merge error.paul
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.
2005-11-032005-11-03 Paul Jakma <paul.jakma@sun.com>paul
* 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.
2005-10-112005-10-11 Paul Jakma <paul.jakma@sun.com>paul
* connected.{c,h}: (connected_{add,delete}_ipv4) label should be const qualified.

* zebra.h: Declare new functions zebra_route_string() and zebra_route_char(). * log.c: (zroute_lookup,zebra_route_string,zebra_route_char) New functions to map zebra route numbers to strings. * zebra_vty.c: (route_type_str) Remove obsolete function: use new library function zebra_route_string() instead. Note that there are a few differences: for IPv6 routes, we now get "ripng" and "ospf6" instead of the old behavior ("rip" and "ospf"). (route_type_char) Remove obsolete function: ues new library function zebra_route_char() instead. Note that there is one difference: the old function returned 'S' for a ZEBRA_ROUTE_SYSTEM route, whereas the new one returns 'X'. (vty_show_ip_route_detail,vty_show_ipv6_route_detail) Replace route_type_str() with zebra_route_string(). (vty_show_ip_route,vty_show_ipv6_route) Replace route_type_char() with zebra_route_char(). * bgp_vty.c: (bgp_config_write_redistribute) Use new library function zebra_route_string instead of a local hard-coded table. * ospf6_asbr.c: Remove local hard-coded tables zroute_name and zroute_abname. Change the ZROUTE_NAME macro to use new library function zebra_route_string(). Remove the ZROUTE_ABNAME macro. (ospf6_asbr_external_route_show): Replace ZROUTE_ABNAME() with a call to zebra_route_char(), and be sure to fix the format string, since we now have a char instead of a char *. * ospf6_zebra.c: Remove local hard-coded tables zebra_route_name and zebra_route_abname. Note that the zebra_route_name[] table contained mixed-case strings, whereas the zebra_route_string() function returns lower-case strings. (ospf6_zebra_read_ipv6): Change debug message to use new library function zebra_route_string() instead of zebra_route_name[]. (show_zebra): Use new library function zebra_route_string() instead of zebra_route_name[]. * ospf_dump.c: Remove local hard-coded table ospf_redistributed_proto. (ospf_redist_string) New function implemented using new library function zebra_route_string(). Note that there are a few differences in the output that will result: the new function returns strings that are lower-case, whereas the old table was mixed case. Also, the old table mapped ZEBRA_ROUTE_OSPF6 to "OSPFv3", whereas the new function returns "ospf6". * ospfd.h: Remove extern struct message ospf_redistributed_proto[], and add extern const char *ospf_redist_string(u_int route_type) instead. * ospf_asbr.c: (ospf_external_info_add) In two messages, use ospf_redist_string instead of LOOKUP(ospf_redistributed_proto). * ospf_vty.c: Remove local hard-coded table distribute_str. (config_write_ospf_redistribute,config_write_ospf_distribute): Use new library function zebra_route_string() instead of distribute_str[]. * ospf_zebra.c: (ospf_redistribute_set,ospf_redistribute_unset, ospf_redistribute_default_set,ospf_redistribute_check) In debug messages, use ospf_redist_string() instead of LOOKUP(ospf_redistributed_proto). * rip_zebra.c: (config_write_rip_redistribute): Remove local hard-coded table str[]. Replace str[] with calls to new library function zebra_route_string(). * ripd.c: Remove local hard-coded table route_info[]. (show_ip_rip) Replace uses of str[] with calls to new library functions zebra_route_char and zebra_route_string. * ripng_zebra.c: (ripng_redistribute_write) Remove local hard-coded table str[]. Replace str[i] with new library function zebra_route_string(i). * ripngd.c: Remove local hard-coded table route_info[]. (show_ipv6_ripng) Use new library function zebra_route_char() instead of table route_info[].
2005-10-012005-10-01 Andrew J. Schorr <ajschorr@alumni.princeton.edu>ajs
* rt_netlink.c: (netlink_request) Use memset to clear structure before calling sendto (eliminates a valgrind error message about uninitialized data).
2005-09-292005-09-29 Alain Ritoux <alain.ritoux@6wind.com>vincent
* lib/filer.c: show protocol name in filter_show() * lib/plist.c: show protocol name in vty_show_prefix_entry() * routemap.c: show protocol name in vty_show_route_map_entry() * lib/vty.c: in vty_command(), show protocol name if command unknown * zebra/zserv.c: Always provide distance fo route add * ripd/rip_snmp.c: rip2IfConfReceive() sends values in conformance with RFC. Also PeerDomain is now set to a STRING type. * ripd/ripd.h: rip_redistribute_add() API includes metric and distance * ripd/ripd.c: rip_redistribute_add() API i.e. stores metric and distance Now allows a RIP-route to overcome a redistributed route coming from a protocol with worse (higher) administrative distance Metrics from redistribution are shown in show ip rip * ripd/rip_zebra.c: adapt to the rip_redistribute_add() API, i.e. provide distance and metric * ripd/rip_interface.c: adapt to the rip_redistribute_add() API * ripd/rip_routemap.c: no RMAP_COMPILE_ERROR on (metric > 16) usage rather a CMD_WARNING, because set metric ius shared with other protocols using larger values (such as OSPF) The match metric action takes first external metric if present (from redistribution) then RIP metric.
2005-09-28 * connected.c: flag connected_up_ipv6() and connected_down_ipv6()vincent
usage with HAVE_IPV6
2005-09-24 * rib.h: Add note about behaviour of rib_add_ipv[46]* functions -hasso
add is treated as implicit withdraw.
2005-09-21 * zebra_rib.c: Reduce the height of some staircases. Fixhasso
rib_delete_ipv6() to match routes in the RIB by their gateway as well as by destination.
2005-09-212005-09-21 Paul Jakma <paul.jakma@sun.com>paul
* zebra_rib.c: (static_uninstall_ipv{4,6}) Fix regression wrt removal of static routes with multiple-hops introduced with the workqueue conversion. We should free the relevant nexthop and then get rib_process to run, otherwise we just get same static route back again (with no way to unconfigure it, because its already deleted from configuration).
2005-09-122005-09-12 Paul Jakma <paul.jakma@sun.com>paul
* (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.
2005-08-27 * zebra_rib.c, rib.h: Add distance and metric arguments to thehasso
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.
2005-07-292005-07-29 Paul Jakma <paul.jakma@sun.com>paul
* 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.
2005-06-282005-06-28 Paul Jakma <paul.jakma@sun.com>paul
* kernel_socket.c: (RTA_{ADDR,ATTR}_GET) fix mistake, NULL check should be on DEST argument
2005-06-282005-06-28 Paul Jakma <paul.jakma@sun.com>paul
* (global) Extern and static'ification, with related fixups of declarations, ensuring files include their own headers, etc. if_ioctl.c: (interface_info_ioctl) fix obvious arg mis-order in list loop
2005-06-142005-06-14 Paul Jakma <paul.jakma@sun.com>paul
* 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
2005-06-12 * rt_netlink.c: Remove unused netlink-addr socket declaration.hasso
* rt_netlink.c (netlink_parse_info): Fix debug messages - nlmsg_pid is unsigned and one zlog call had swapped arguments. * rt_netlink.c (netlink_route_multipath): Fix compile with disabled IPv6 support. [backport candidate] - with stuff commited to rt_netlink.c before to fix logging in netlink_route_multipath().
2005-05-312005-05-31 Paul Jakma <paul.jakma@sun.com>paul
* zserv.c: (zsend_route_multipath) Fix bug if route is sent with no NEXTHOP_FLAG_FIB nexthops. As ZAPI_MESSAGE_IFINDEX and ZAPI_MESSAGE_NEXTHOP are always set, clients would try read non-existent nexthop information and hit stream assert. Zserv is still broken for multi-nexthop messages, but it always was.
2005-05-062005-05-06 Paul Jakma <paul.jakma@sun.com>paul
* zserv.h: Remove ZEBRA_PORT definition, its in lib/zebra.h now
2005-04-282005-04-28 Paul Jakma <paul.jakma@sun.com>paul
* rib.h: (struct rib) Add lock field for refcounting. * zserv.h: (struct zebra_t) Add a ribq workqueue to the zebra 'master' struct. * zserv.c: (zread_ipv4_add) XMALLOC then memset should be XCALLOC. * zebra_rib.c: Clean up refcounting of route_node, make struct rib refcounted and convert rib_process to work-queue. In general, rib's should be rib_addnode'd and delnode'd to route_nodes, and these symmetrical functions will manage the locking of referenced route_node and freeing of struct rib - rather than having users manage each seperately - with much scope for bugs.. (newrib_free) removed and replaced with rib_lock (rib_lock) new function, check state of lock and increment. (rib_unlock) new function, check lock state and decrement. Free struct rib if refcount hits 0, freeing struct nexthop's, as newrib_free did. (rib_addnode) Add RIB to route_node, locking both. (rib_delnode) Delete RIB from route_node, unlocking each. (rib_process) Converted to a work-queue work function. Functional changes are minimal, just arguments, comments and whitespace. (rib_queue_add_qnode) Helper function to setup a ribq item. (rib_queue_add) Helper function, same arguments as old rib_process, to replace in callers of rib_process. (rib_queue_qnode_del) ribq deconstructor. (rib_queue_init) Create the ribq. (rib_init) call rib_queue_init. (remainder) Sanitise refcounting of route_node's. Convert to rib_queue_add, rib_addnode and rib_delnode. Change XMALLOC/memset to XCALLOC. Remove calls to nexthop_delete and nexthop_free.
2005-04-102005-04-10 Paul Jakma <paul@dishone.st>paul
* if_ioctl_solaris.c: (if_lookup_linklocal) fix order of args in ALL_LIST_ELEMENTS_RO macro.
2005-04-102005-04-10 Andrew J. Schorr <ajschorr@alumni.princeton.edu>ajs
* zserv.c (zebra_client_read): Fix bug: first read attempt should read ZEBRA_HEADER_SIZE minus the number of bytes already read. Improve efficiency by maintaining a calculation of the number of bytes read instead of calling stream_get_endp multiple times. If message length is too small, issue a warning message (not debug) before closing the connection. And also check that message length is not too big.
2005-04-09 * rt_netlink.c: One tiny missing comma caused pointless debug messageshasso
about IPv6 nexthops.
2005-04-09 * rt_netlink.c (netlink_parse_info): Fix warning. It's safe to casthasso
status to unsigned here, because we already checked that it isn't negative or 0. * rt_netlink.c (netlink_interface_addr): Prefix length belongs to the address, not to the interface. * rt_netlink.c (netlink_route_multipath): Fix debug. No useless info is printed out now and IPv6 info is handeled.
2005-04-052004-04-05 Paul Jakma <paul@dishone.st>paul
* lib/vty.c: Improve logging of failures to open vty socket(s). See bugid #163. * zebra/zserv.c: print more helpful errors when we fail to successfully bind and listen on zserv socket. Closes bugzilla #163.
2005-04-032005-04-02 Andrew J. Schorr <ajschorr@alumni.princeton.edu>ajs
* 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.
2005-04-022005-04-02 Andrew J. Schorr <ajschorr@alumni.princeton.edu>ajs
* if.h: (if_lookup_by_name_len, if_get_by_name_len) New functions. * if.c: (if_lookup_by_name_len, if_get_by_name_len) New functions. (if_get_by_name) Tighten up code. (interface) Use new function if_get_by_name_len. * zclient.c: (zebra_interface_add_read) Use new if_get_by_name_len function. (zebra_interface_state_read) Use new if_lookup_by_name_len function. * kernel_socket.c: (ifm_read) Use new if_lookup_by_name_len function to save a memcpy. * if_ioctl_solaris.c: (interface_list_ioctl) Fix subtle bug with new if_get_by_name_len function. * ospf_interface.c: (ospf_vl_new) Use strnlen to fix call to if_create.
2005-04-022005-04-02 Andrew J. Schorr <ajschorr@alumni.princeton.edu>ajs
Fix problems when netlink interfaces are renamed (same ifindex used for a new interface). Start cleaning up some problems with the way interface names are handled. * interface.c: (if_new_intern_ifindex) Remove obsolete function. (if_delete_update) After distributing the interface deletion message, set ifp->ifindex to IFINDEX_INTERNAL. (if_dump_vty) Detect pseudo interface by checking if ifp->ifindex is IFINDEX_INTERNAL. (zebra_interface) Check return code from interface_cmd.func. Do not set internal ifindex values to if_new_intern_ifindex(), since we now use IFINDEX_INTERNAL for all pseudo interfaces. * kernel_socket.c: (ifm_read) Fix code and comments to reflect that all internal interfaces now have ifp->ifindex set to IFINDEX_INTERNAL. * rt_netlink.c: (set_ifindex) New function used to update ifp->ifindex. Detects interface rename events by checking if that ifindex is already being used. If it is, delete the old interface before assigning the ifindex to the new interface. (netlink_interface, netlink_link_change) Call set_ifindex to update the ifindex. * if.h: Remove define for IFINDEX_INTERNBASE and add define IFINDEX_INTERNAL 0, since all internal (i.e. non-kernel) pseudo- interfaces should have ifindex set to 0. (if_new) Remove function. (if_delete_retain) New function to delete an interface without removing from iflist and freeing the structure. (ifname2ifindex) New function. * if.c: (if_new) Remove function (absorb into if_create). (if_create) Replace function if_new with call to calloc. Set ifp->ifindex to IFINDEX_INTERNAL. Fix off-by-one error in assert to check length of interface name. Add error message if interface with this name already exists. (if_delete_retain) New function to delete an interface without removing from iflist and freeing the structure. (if_delete) Implement with help of if_delete_retain. (ifindex2ifname) Reimplement using if_lookup_by_index. (ifname2ifindex) New function to complement ifindex2ifname. (interface) The interface command should check the name length and fail with a warning message if it is too long. (no_interface) Fix spelling in warning message. (if_nametoindex) Reimplement using if_lookup_by_name. (if_indextoname, ifaddr_ipv4_lookup) Reimplement using if_lookup_by_index. * bgp_zebra.c: (bgp_interface_delete) After deleting, set ifp->ifindex to IFINDEX_INTERNAL. * isis_zebra.c: (isis_zebra_if_del) Call if_delete_retain instead of if_delete, since it is generally not safe to remove interface structures. After deleting, set ifp->ifindex to IFINDEX_INTERNAL. (zebra_interface_if_lookup) Tighten up code. * ospf6_zebra.c: (ospf6_zebra_if_del) Previously, this whole function was commented out. But this is not safe: we should at least update the ifindex when the interface is deleted. So the new version updates the interface status and sets ifp->ifindex to IFINDEX_INTERNAL. (ospf6_zebra_route_update) Use if_indextoname properly. * ospf_vty.c: (show_ip_ospf_interface_sub) Show ifindex and interface flags to help with debugging. * ospf_zebra.c: (ospf_interface_delete) After deleting, set ifp->ifindex to IFINDEX_INTERNAL. (zebra_interface_if_lookup) Make function static. Tighten up code. * rip_interface.c: (rip_interface_delete) After deleting, set ifp->ifindex to IFINDEX_INTERNAL. * ripng_interface.c: (ripng_interface_delete) After deleting, set ifp->ifindex to IFINDEX_INTERNAL.
2005-03-31 * rt_netlink.c (netlink_talk_filter): Show always warning message,hasso
it's not for debug. * rt_netlink.c (netlink_talk): Don't assume we use netlink_cmd although we do now actually. * rt_netlink.c (netlink_route, netlink_route_multipath): Always use netlink_cmd to send messages to the kernel. [backport candidate]

* irdp.h: Add prototype for irdp_sock_init, and fix protos for other irdp_* functions. * irdp_interface.c: (irdp_if_start) If irdp_sock is negative, call irdp_sock_init to create the IRDP socket. (irdp_if_init) Rename to irdp_init(). (get_iflist_ifp) Remove function that is a duplicate of if_lookup_by_index. (*) Make many functions static. And remove superfluous "\n" from several zlog messages. * irdp_main.c: (irdp_init) Remove function that used to call irdp_if_init() and irdp_sock_init(), since we will now create the socket only upon first use. (irdp_sock_init) Do not update global irdp_sock variable, just return the fd and assume that the caller will do so. If setsockopt calls fail, close the socket before returning -1. (*) Make many functions static. * irdp_packet.c: Initialize irdp_sock to -1. (irdp_read_raw) Call standard library function if_lookup_by_index instead of get_iflist_ifp. (irdp_recvmsg) Should be static, not global.

* rt_netlink.c: (netlink_link_change) If the status of an operative interface changes (e.g. MTU changes), the client daemons should be notified by calling zebra_interface_up_update. Previously, the information was being updated in zebra's interface structure, but the clients were not notified of changes to an operative interface. * ospf_zebra.c: (ospf_interface_state_up) If the MTU of an operative interface changes, print a debug message and call ospf_if_reset() to simulate down/up on the interface. * ospf_interface.h: Declare new function ospf_if_reset(). * ospf_interface.c: (ospf_if_reset) New function to call ospf_if_down and ospf_if_up for all ospf interfaces attached to an interface.
