2006-12-12[PtP over ethernet] New peer flag allows much more addressing flexibilityAndrew J. Schorr
2006-12-12 Andrew J. 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.
2006-09-11[ripd] bug #293: routemap set metric doesn't check for underflow correctlyPaul Jakma
2006-09-11 Paul Jakma <paul.jakma@sun.com> * rip_routemap.c: (route_set_metric) underflow check needs to use signed, problem identified and diagnosed by Pavel Nikiforov in bug #293.
2006-09-11[ripd] bug #278: remove gratuitous use of mid-function declarationPaul Jakma
2006-09-11 Paul Jakma <paul.jakma@sun.com> * ripd.c: (rip_read) remove gratuitous use of mid-function declaration of vrecv, bug #278.
2006-06-30[ripd] update to use auto-generated redistribute route-type defsPaul Jakma
2006-06-29 Paul Jakma <paul.jakma@sun.com> * rip_zebra: (general) convert redistribute commands to use the auto-generated defines.
2006-05-04[ripd] bugs #261, #262: Fix RIPv1 info-leak and unauthenticated route updatesPaul Jakma
2006-05-04 Paul Jakma <paul.jakma@sun.com> * (general) Fixes for bugs #261 and 262. Thanks to Konstantin V. Gavrilenko <kos@arhont.com> for the problem reports, testing of a series of proposed patches and comment on the proposed changes in behaviour. * rip_interface.c: (ip_rip_authentication_mode_cmd) Parse all of the command before making any changes to configured state. * ripd.c: (rip_read) RIP version control should be absolute and always apply, fixes bug #261 by allowing RIPv1 to be disabled. Fix bug #262: If authentication is enabled, then unauthenticated packets should not be accepted. We do however make an exception for RIPv1 REQUEST packets, to which we will reply as RIPv1 can now be disabled fully, to allow ripd to still provide routing /information/ to simple devices.
2006-04-28[ripd] Fix logic to send updates on all connected addresses.Andrew J. Schorr
2006-04-28 Andrew J. Schorr <ajschorr@alumni.princeton.edu> * ripd.c: (rip_update_process) Try to fix the logic for sending an updated on each connected network. The new code will attempt to send the update on each connected network, whereas the previous code seemed to be attempting to avoid sending more than one RIPv1 update on a given interface, but was coded incorrectly. The actual effect of the old code was to send an update only on the first connected address in the cases where the interface is not multicast, or RIPv2 is not being used.

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.
2006-01-17[ripd] Fix verification of received MD5 authenticated packetspaul
2006-01-17 Paul Jakma <paul.jakma@sun.com> * ripd.c: (rip_auth_md5) remove pdigest, not needed. Use a local buffer for the auth_str, where it can be properly nul padded. Do so, hence fixing MD5 authentication. Key looked up via key ring should be used in preference to the RIPv1 simple password, not other way around. No need to copy around digests, we can reference them directly. The auth_len received can't be trusted, some implementations lie (e.g. older ripd). (rip_auth_md5_ah_write) rename len local variable to doff to be consistent with other functions. (rip_auth_header_write) add the missing return. (rip_auth_md5_set) use the proper constructs to access stream.

* ripd.c: (rip_response_process) Instead of calling rip_interface.c:if_valid_neighbor(), call the equivalent library function if_lookup_address(). * rip_interface.c: (if_valid_neighbor) Remove function, since it is essentially equivalent to the if_lookup_address() library function. * ripd.h: (if_valid_neighbor) Remove function declaration.
2005-10-282005-10-28 Paul Jakma <paul.jakma@sun.com>paul
* Makefile.am: Add rip_interface.h, or else it doesn't get included in dists.
2005-10-252005-10-26 Paul Jakma <paul.jakma@sun.com>paul
* ripd.c: Update couple more functions to specify void explicitely.
2005-10-252005-10-26 Paul Jakma <paul.jakma@sun.com>paul
* (general) static/extern functions and definitions. * rip_interface.h: new file, export the public functions from rip_interface.c
2005-10-192005-10-17 Vincent Jardin <vincent.jardin@6wind.com>jardin
* ripd.c: rip_create_socket() for each packet, it does not bind to the proper interfaces because we forget to use the from address when it is specified.
2005-10-062005-10-06 Alain Ritoux <alain.ritoux@6wind.com>vincent
* rip_interface.c: Now the command "no ip rip split-horizon poisoned-reverse" just inhibates the poisoned-reverse effects but keep spli-horizon activ.
2005-10-012005-10-01 Andrew J. Schorr <ajschorr@alumni.princeton.edu>ajs
* 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[].

* ripd.c: (general) Fix previous commit, broke multicast bind and hence setting of source port, which broke communication with non-borken ripd. Fix removes more stuff from rip_interface.c than it adds to ripd.c ;) (rip_create_socket) the to argument really is a from argument, rename it. Set the source port to RIP port unconditionally, it's required. (rip_send_packet) Set from address correctly for multicast. (rip_output_process) trivial: num can be BSS specified, rather than in body. * rip_interface.c: (rip_interface_multicast_set) strip out redundant stuff related to bind, which rip_create_socket does. Just make it set the multicast socket option, as per the interface concerned, no more.
2005-06-032005-06-03 Paul Jakma <paul.jakma@sun.com>paul
* ripd.c: (rip_create_socket) Make it static. Remove the getservbyname stuff, as RFC2453 3.9.2 says non-RIP port messages should be discarded, quagga doesnt accept them, no need to lookup port. Take a 'to' argument, if socket should be bound to something else. setsockopt_so_recvbuf might need privs, move it to the raised privileges section. dont forget to close the socket if bind fails. (rip_send_packet) use strncpy, just in case (address is under our control anyway, but still). dont duplicate rip_create_socket - just use it. (rip_create) rip_create_socket takes an argument now, modify.
2005-06-032005-06-03 Paul Jakma <paul.jakma@sun.com>paul
* ripd.c: (rip_create_socket) move it up so rip_send_packet can use it too.

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.

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.

* ripd.c: Untangle the construction of RIP auth data. (rip_auth_prepare_str_send) new helper function, prepare correct key string. (rip_auth_simple_write) new helper, write out the rip simple password auth psuedo-RTE. (rip_auth_md5_ah_write) new helper, write out the MD5 auth-header psuedo-RTE. (rip_auth_header_write) new helper, write out correct auth header data / psuedo-RTE. (rip_auth_md5_set) rip out the memmove and writing of the auth header psuedo-RTE. So that all that is left is to write the trailing auth digest, and update digest offset field in the original header. (rip_write_rte) rip out writing of RIP header, writing of simple auth data psuedo-RTE. Make it do what its name suggests, write out actual RTEs. (rip_output_process) remove the incorrect additional decrements of rtemax. Prepare the auth_str, which simple or MD5 auth will need. Move write out of RIP header and auth data to inside the loop. Adjust paramaters as required.

* bgp_main.c: (main) The 2nd argument to openzlog has been removed. * isis_main.c: (main) The 2nd argument to openzlog has been removed. * ospf6_main.c: (main) The 2nd argument to openzlog has been removed. Note that stdout logging will no longer be enabled by default when not running as a daemon. * ospf_main.c: (main) The 2nd argument to openzlog has been removed. * rip_main.c: (main) The 2nd argument to openzlog has been removed. * ripng_main.c: (main) The 2nd argument to openzlog has been removed. * main.c: (main) The 2nd argument to openzlog has been removed. So stdout logging will no longer be enabled by default. * irdp_main.c: (irdp_finish) Reduce severity of shutdown message from LOG_WARNING to LOG_INFO. * vtysh.c: Make several functions static instead of global. Added several commands to support destination-specific logging levels. (vtysh_completion) This function is unused, so comment it out. * basic.texi: Document new logging features. Separate basic config commands from basic VTY commands. * log.h: Replace struct zlog flags and maskpri fields with maxlvl array to support individual logging levels for each destination. Remove the 2nd argument to openzlog since the default logging config should be standardized inside the library. Replaced the zlog_set_flag and zlog_reset_flag functions with zlog_set_level. And zlog_set_file now requires an additional log_level argument. Declare zlog_proto_names for use inside command.c in the "show logging" command. Added defines useful for command construction. * log.c: (vzlog) Decide where to send the message based on the individual logging levels configured for each destination. Remove support for ZLOG_STDERR since it was never actually used. Support record-priority for terminal monitors. (zlog_signal,zlog_backtrace_sigsafe) Support destination-specific logging levels. Remove stderr support (was never used). Added support for terminal monitor logging. (_zlog_assert_failed) Increase message severity to LOG_EMERG. (openzlog) Remove 2nd argument since default config should be standardized in library. By default, terminal monitoring is set to debug, and all other logging is disabled. (zlog_set_flag,zlog_reset_flag) Removed. (zlog_set_level) New function to replace zlog_set_flag and zlog_reset_flag. Supports destination-specific logging levels. (zlog_set_file,zlog_reset_file) Support file-specific logging level. (zlog_rotate) Log an error message if fopen fails, and support new file-specific logging level. * command.h: Change DEFUN_CMD_FUNC_DECL and DEFUN_CMD_FUNC_TEXT so that command functions will be static instead of global. Remove declarations for config_exit and config_help. Define new macros DEFUNSH_ATTR, DEFUNSH_HIDDEN, and DEFUNSH_DEPRECATED so we can have deprecated commands in vtysh. Similarly, for completeness, define macros ALIAS_SH, ALIAS_SH_HIDDEN, and ALIAS_SH_DEPRECATED. Also, fix bug in ALIAS_ATTR macro (didn't matter because it was never used). * command.c: Make many functions static instead of global. (facility_name,facility_match,level_match) New functions to support enhanced destination-specific logging levels. (config_write_host) Support new destination-specific logging levels. (config_logmsg) Added new "logmsg" command to help test logging system. (show_logging) Added "show logging" command to show the current configuration of the logging system. (config_log_stdout_level) Support explicit stdout logging level. (no_config_log_stdout) Now takes optional LEVEL arg. (config_log_monitor,config_log_monitor_level,no_config_log_monitor) New commands creating new "log monitor" commands to set terminal monitoring log level. (config_log_file_level) Support explicit file logging level. (config_log_syslog_level) Support explicit syslog logging level. (config_log_facility,no_config_log_facility) Implement new "log facility" command. (cmd_init) Add hooks for new commands: "show logging", "logmsg", "log stdout <level>", "log monitor", "log monitor <level>", "no log monitor", "log file <filename> <level>", "no log file <filename> <level>", "log syslog <level>", "log facility", and "no log facility". * vty.h: Added a "level" argument to vty_log so it can support "log record-priority". Declare new function vty_log_fixed for use in signal handlers. * vty.c: (vty_log,vty_log_out) Added a "level" argument to support "log record-priority" for vty terminal monitors. (vty_down_level) Use config_exit_cmd.func instead of calling config_exit directly (since command functions will now be static instead of global). (vty_log_fixed) New function to send terminal monitor messages from inside a signal handler.

* bgp_main.c: (sigint) Use zlog_notice for termination message. (main) Use zlog_notice for startup announcement. * isis_main.c: (sigint,sigterm) Use zlog_notice for termination message. (terminate) This function should be static, not global. (main) Use zlog_notice for startup announcement, and remove ifdef ZEBRA_VERSION. * version.h.in: Remove declaration for pid_output_lock, this function is now static, not global. * pid_output.c: (pid_output_lock) This function should be static, not global. And remove "old umask" error message, since it was really an unimportant debug message, not an error. (pid_output) Need to declare static function pid_output_lock. * ospf6_main.c: (sigint,sigterm) Use zlog_notice for termination message. (main) Remove commented-out call to pid_output_lock (which should never be called other than from inside pid_output). And use zlog_notice to print the startup message, which now includes the vty port. * ospf_main.c: (sigint) Use zlog_notice for termination message. (main) Issue a startup announcement using zlog_notice. * rip_main.c: (sigint) Use zlog_notice for termination message. (main) Add a startup announcement using zlog_notice. * ripng_main.c: (sighup) Remove spurious terminating message. (sigint) Use zlog_notice for termination message. (main) Issue a startup announcement using zlog_notice. * main.c: (sigint) Use zlog_notice for termination message. (main) Add a startup announcement using zlog_notice.
2004-11-25Make group to run daemon as configurable. Fixes #2 from Bugzilla #64.hasso
2004-10-222004-10-22 Paul Jakma <paul@dishone.st>paul
* ripd.c: Collapse redundant passing of various address structs, struct interface and struct connected as arguments to functions down to two key arguments, namely struct connected and, possibly, address of source/destination. Testing for RIPv1 would be useful. (rip_read) lookup struct connected for the received packet, pass it on. * rip_interface.c: With previous changes, we no longer have to tread carefully with struct connected, as it will always be there and valid.
2004-10-19OK. Here it is - PtP patch from Andrew J. Schorr. No problems with ospfd,hasso
ripd might need some more testing though.
2004-10-13Make initializing smux connection configurable - "smux peer OID" commandhasso

* rip_interface.c: (rip_interface_multicast_set) get rid of extraneous if_pointopoint arg. ifp is accessible via connected. pass connected->ifp->ifindex to setsockopt_multicast_ipv4. * ripd.c: (rip_send_packet) update call to rip_interface_multicast_set * ripd.h: update rip_interface_multicast_set prototype
2004-06-112004-06-11 Sowmini Varadhan <sowmini.varadhan@sun.com>paul
* filter.c: (access_list_remark_cmd) buffer_putstr doesnt need cast to u_char. (ipv6_access_list_remark_cmd) ditto. if.c: ditto * network.c: (readn/writen) pointer arg should be type u_char. * plist.c: needs to include stream.h, not declare stream functions internally. (various) Add static qualifier to internal functions. (prefix_list_type_str) extraneous breaks in switch statement. (ip_prefix_list_description_cmd) buffer_putstr doesnt need cast * stream.h: depends on plist.h and export stream_put_prefix * vty.c: (vty_<telnet option build functions>) should use unsigned char, telnet options are 0 -> 255. * zclient.c: various u_char<->char type cleanups. * zebra.h: Having to define CMSG_* can apply to more than just BSDI_NRL. * ripd.c: (rip_distribute_update_all) distribute list hook function pointer prototype requires struct prefix_list * arg. (rip_distribute_update_all_wrapper) update to pass required arg, NULL.
2004-06-062004-06-06 Paul Jakma <paul.jakma@sun.com>paul
* ripd.h: Add define for the RIPv2 Authentication Data family Move the auth type defines up to where other defines live. Add RIP_AUTH_MD5_COMPAT_SIZE, for backwards compatible md5->auth_len size. Add md5_auth_len field to struct rip_interface: (rip_interface_new) Init md5_auth_len to compatible size. (ip_rip_authentication_mode_cmd) Extended to handle setting md5 auth-length. Appropriate aliases added. (no_ip_rip_authentication_mode_cmd) Reset md5_auth_len to compatible size. (rip_interface_config_write) Teach it about md5_auth_len. _always_ write out the auth-length, so that everyone will get the setting in their config file, and hence allow for a future change of default for md5_auth_len to be less painful - every md5 user will have this setting in their config file. ripd.c: (rip_packet_dump) Change nasty hard coded constants to symbolic defines. Change various tests of 'ntoh.(variable) == constant' to test 'variable == ntoh.(constant)'. Clean up indentation on some long lines. (rip_auth_simple_password) ditto. (rip_auth_md5) ditto, also add length argument and sanity check md5 data offset field. Sanity check md5 auth length, accept RFC or old-ripd/cisco lengths. (rip_auth_md5_set) as per (rip_packet_dump), also write out the configured md5 auth length for the interface (old-ripd or rfc) (rip_read) as per (rip_packet_dump) (rip_write_rte) ditto (rip_response_process) ditto (rip_write_rte) ditto
2004-06-042004-06-04 JJ Ludman <jacques.ludman@sun.com>paul
* ripd.c: Interoperability fix. Correct value for MD5 auth length is 16. Accept packets with this set to >= 16, and set to 16 ourselves.
