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.
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[].

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.
2005-04-08 * prefix.[hc]: Pass argument to the inet6_ntoa by value making it morehasso
inet_ntoa alike. * ripngd.[hc], ripng_interface.c, ripng_peer.c: inet6_ntoa() takes argument now by value.
2005-04-05 * lib/prefix.[hc]: inet6_ntoa utility function copied fromhasso
ripngd/ripngd.c (inet6_ntop). * ripngd.[hc]: Remove inet6_ntop() and any usage of it. inet6_ntoa() from lib is used now. * ripng_interface.c: inet6_ntop() -> inet6_ntoa(). * ripng_peer.c: inet6_ntop() -> inet6_ntoa().

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.

* ripng_interface.c: (ripng_multicast_join) Save errno before calling ripngd_privs.change.
2005-01-042005-01-04 Andrew J. Schorr <ajschorr@alumni.princeton.edu>ajs
* configure.ac: Added test for broken CMSG_FIRSTHDR macro (relevant for Solaris 8 and unpatched Solaris 9, don't know whether other platforms are affected). * zebra.h: Define ZCMSG_FIRSTHDR appropriately based on whether config.h indicates HAVE_BROKEN_CMSG_FIRSTHDR (as determined by the configure test program). * sockopt.c: (getsockopt_cmsg_data) Use ZCMSG_FIRSTHDR instead of CMSG_FIRSTHDR. * rtadv.c: (rtadv_recv_packet,rtadv_send_packet) Use ZCMSG_FIRSTHDR instead of CMSG_FIRSTHDR. * ripd.c: (rip_recvmsg) Use ZCMSG_FIRSTHDR instead of CMSG_FIRSTHDR. * ripngd.c: (ripng_recv_packet) Use ZCMSG_FIRSTHDR instead of CMSG_FIRSTHDR.

* ripng_nexthop.c: Replace NEXTHOP_OUT macro with NEXTHOP_OUT_PTR, since it's not really OK to take the address of a ternary expression. (_ripng_rte_cmp,ripng_rte_send) Use new NEXTHOP_OUT_PTR macro instead of NEXTHOP_OUT.
2004-12-082004-12-08 Andrew J. Schorr <ajschorr@alumni.princeton.edu>ajs
* *.c: Change level of debug messages to LOG_DEBUG.

* 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.

2004-01-04Really 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).
