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.

* (global) update all c files to match the lib/vector.h rename of (struct vector).active to max, and vector_max macro to vector_active. * lib/vector.h: Rename to (struct vector).max to slightly less confusing active, for the number of active slots, distinct from allocated or active-and-not-empty. Rename vector_max to vector_active for same reason.

* ripng_interface.c: (ripng_multicast_join) Save errno before calling ripngd_privs.change.
2004-12-082004-12-08 Andrew J. Schorr <ajschorr@alumni.princeton.edu>ajs
* *.c: Change level of debug messages to LOG_DEBUG.
2004-11-202004-11-19 Andrew J. Schorr <ajschorr@alumni.princeton.edu>ajs
* global: Replace strerror with safe_strerror. And vtysh/vtysh.c needs to include "log.h" to pick up the declaration.

2004-01-04Really ripngd should either leave groups on down interfaces, or keepgdt
track of on which interfaces joins have occurred. This is complicated by the possible lack of a clear behavior spec on whether interfaces keep their joined group lists across a down/up/down transition. (On NetBSD, they do.) 2004-01-03 Greg Troxel <gdt@ahi.ir.bbn.com> * ripng_interface.c (ripng_multicast_join): If IPV6_JOIN_GROUP returns EADDRINUSE, consider the join successful. This happens when an interface goes down and comes back because ripng_multicast_leave does not invoke the LEAVE_GROUP operation if the interface is down. Solves problem of ripng stopping working on an interface which goes down and then comes back up (on NetBSD).

2003-05-23From: Hasso Tepper <hasso@estpak.ee>paul
Add the 'no interface' command to all the daemons and vtysh. now it's possible to delete interface from routeing daemons as well only if it doesn't exist in os. http://hasso.linux.ee/zebra/ht-no_interface_fix.patch
2003-05-23Undo Hasso last patch, about to apply a slightly updated patch.paul
