2006-05-15[lib] Add string mapping table for Zserv commandsPaul Jakma
2006-05-15 Paul Jakma <paul.jakma@sun.com> * log.c: (general) Generalise struct zebra_route_desc into struct zebra_desc_table and, similar to route_types, add a command_types table to describe Zserv protocol commands. (route_types[]) use a macro to use designated initialisers while avoiding tedious duplication. (zserv_command_string) lookup string from zebra_desc_table, similar to zebra_route_string * zebra.h: Add declaration for zserv_command_string, adjust the comments to reflect zebra_desc_table.

* 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[].

* log.c: (zlog_signal,zlog_backtrace_sigsafe) Eliminate use of fileno() since it is not async-signal-safe. (_zlog_assert_failed) Rewrite crashlog logic more compactly. (zlog_set_file,zlog_reset_file,zlog_rotate) Update logfile_fd for use in signal handler.
2005-02-032005-02-03 Andrew J. Schorr <ajschorr@alumni.princeton.edu>ajs
* log.c: (syslog_sigsafe) Reduce scope of syslog_fd: it is accessed inside this function only. (open_crashlog) New function to open /var/tmp/quagga.<daemon>.crashlog with flags O_WRONLY|O_CREAT|O_EXCL to save some crash info. (zlog_signal,_zlog_assert_failed) Increase logging priority from LOG_ERR to LOG_CRIT. If no file logging is configured, try to use open_crashlog to create a crash logfile. (zlog_backtrace_sigsafe) If a crashlog file descriptor is open, dump a backtrace to that file.

* log.h: Test for SA_SIGINFO to see whether zlog_signal takes final two args (siginfo and program_counter). * log.c: (hex_append) Include this function only if SA_SIGINFO or HAVE_GLIBC_BACKTRACE is defined. (zlog_signal) Final two args (siginfo and program_counter) now depend on whether SA_SIGINFO is defined on this platform. * sigevent.c: (program_counter) Do not include this function if SA_SIGINFO is not defined on this platform. (exit_handler,core_handler) Test for SA_SIGINFO to decide whether 2nd & 3rd arguments are present and to decide how to invoke zlog_signal. (trap_default_signals) Test for SA_SIGINFO and invoke sigaction appropriately.
2005-01-172005-01-17 Andrew J. Schorr <ajschorr@alumni.princeton.edu>ajs
* log.h: Change prototype for zlog_backtrace_sigsafe to take additional program_counter argument. * log.c: (zlog_backtrace_sigsafe) Add additional program_counter argument. If it is non-NULL, use backtrace_symbols_fd to resolve the address. (zlog_signal) Call zlog_backtrace_sigsafe with additional program_counter argument. [pullup candidate]

* configure.ac: Test for header file <ucontext.h> (for use in signal processing). * sigevent.c: (trap_default_signals) Use the SA_SIGINFO flag to pass additional siginfo_t and ucontext_t arguments to core_handler and exit_handler. (core_handler,exit_handler) Now invoked with 3 arguments (using SA_SIGINFO). Pass additional info to zlog_signal. (program_counter) New function to find program counter in ucontext_t, needs to be enhanced to support more platforms (currently works only on Linux/x86). * log.h: Change the zlog_signal prototype to add new arguments siginfo_t * and program_counter. * log.c: (zlog_signal) Add new arguments siginfo and program_counter. Include si_addr and program counter (if non-NULL) in message. And remove #ifdef HAVE_GLIBC_BACKTRACE around hex_append, since that is now used to render the si_addr and PC pointers.

* log.c: (zlog_signal,_zlog_assert_failed) Change logging level back to LOG_ERR instead of LOG_EMERG.
2004-12-092004-12-09 Andrew J. Schorr <ajschorr@alumni.princeton.edu>ajs
* log.c: (hex_append) No need to include this function if HAVE_GLIBC_BACKTRACE is not defined.
2004-12-09add XXX comment about hex_append being unused.gdt
(only used if HAVE_GLIBC_BACKTRACE, so perhaps ifdef it?)

* 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.

* log.h: Remove several unused fields from struct zlog. Add comments for other fields, and add one new field syslog_options that is used in the new syslog_sigsafe implementation. * log.c: (syslog_sigsafe) New function to send syslog messages in an async-signal safe way that can be used inside a signal handler. (syslog_connect) New function to connect to syslog daemon inside a signal handler. This function supports only systems where /dev/log is a unix datagram socket (e.g. not Solaris). (zlog_signal) Call syslog_sigsafe if syslog logging is enabled. (zlog_backtrace_sigsafe) Call syslog_sigsafe if syslog logging is enabled. (openzlog) Save syslog_options for use in syslog_sigsafe. (num_append) Fix bug: handle 0 properly. (hex_append) New function to print a u_long in hex format.

* log.c: (zlog_backtrace) New function to log a backtrace. (zlog_backtrace_safe) Log a backtrace in an async-signal-safe way. Unfortunately, this function does not support syslog logging yet. (zlog_signal) Move backtrace code into separate function zlog_backtrace_safe. (_zlog_assert_failed) Call zlog_backtrace before aborting. * log.h: Declare new functions zlog_backtrace and zlog_backtrace_safe. * memory.c: (zerror) Call zlog_backtrace before aborting.
2004-11-24In zlog_signal, should probably check the return code from backtrace, justajs
to be safe.
2004-11-24In zlog_signal, change type of size since backtrace actually returns an int.ajs

* sigevent.c: (signal_init) Set up some default signal handlers so that processes will issue an error message before terminating or dumping core. (trap_default_signals) New function to set up signal handlers for various signals that may kill the process. (exit_handler) Call zlog_signal, then _exit. (core_handler) Call zlog_signal, then abort. * log.h: Declare new function zlog_signal. * log.c: (zlog_signal) New function to log information about a received signal before the process dies. Try to log a backtrace also. (quagga_signal_handler,signal_set) Should be static.

* log.c: (vzlog) Take a single va_list argument and use va_copy as necessary for multiple traversals. (zlog) Pass only one va_list to vzlog. (zlog_*,plog_*) Use a macro for boilerplate code; pass only one va_list to vzlog. (zlog_set_file) Remove unused 2nd argument (flags). (zlog_save_cwd,zlog_get_cwd,zlog_free_cwd) Remove unused functions. * log.h: Remove ZLOG_*_INDEX defines (no longer used). Remove unused 2nd argument from zlog_set_file prototype. Fix prototype for zlog_rotate. * command.c: (config_log_file) Remove unused 2nd arg to zlog_set_file. * vty.c: (vty_out) Fix stdarg usage to perform multiple traversals properly. (vty_log) Must use va_copy for multiple traversals of va_list arg.
