* Further improvements to "pipework".ex19pChris Hall2011-09-061-3/+4
| | | | | | | | | | | | | Version advanced to 0.99.18ex19p. Fixed occasional failure to immediately display prompt after previous command output was abandonned by ^C, particularly with "--more--". Completely removed the "~" temporary prompt, and simplified some logic. Added indication of pthread running to "show version".
* Update pipework and improve memory reporting.Chris Hall2011-07-211-36/+82
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Improve error handling for all new pipework inputs and outputs. Change behaviour of ^C from VTY Terminal, so that will interrupt output and terminate all running pipes -- including running shell commands. In pipe commands, recognise "~/..." and "~user/..." home directory forms. Changed "~/" to mean the usual home for the current user. "~~/" now means the configuration file directory. Introduced "shdir DIR" command to show what is (currently) what. Changed "<|" so that if the command has a path, it is expanded using Quagga's rules (including "~~/" and "~./") and the "here" directory is set to that path. Fixed collection of stderr output from all pipes so that is separate from stdout output, and is always sent to the base output (eg VTY Terminal). Increase amount of information about the heap that "show mem" shows -- particularly if the "memory_tracker" is enabled. Tested and applied resulting fixes.
* Small improvements to speed of reading of configuration file.Chris Hall2011-03-311-1/+2
| | | | | Tidy up signalling of "ready" to command loop, and checking of appropriate state to close written configuration file.
* Merge branch 'master' of /git/quagga.euro-ix into pipeworkex16pChris Hall2011-03-291-1/+2
|\ | | | | | | | | | | | | | | | | | | | | | | | | | | | | This ensures that the two branches are consistent after the merging of the old-Quagga 0.99.18 changes. Release: 0.99.18ex16p. Eliminated some whitespace differences ! Collected RESTRICTED_NODE show_bgp_ipv6_safi_route_cmd and show_bgp_ipv6_safi_prefix_cmd, and one HAVE_IPV6 skip. Also releasing filename in closezlog(). Removed strlen() from lib/qfstring.c for async-signal-safe purposes.
| * Bring "ex" version up to date with 0.99.18ex14Chris Hall2011-03-291-3/+6
| | | | | | | | | | | | | | | | Release: 0.99.18ex14 Also fixes issue with unknown attributes -- does not release them prematurely. Contains the "bgpd: New show commands for improved view and address family support", which is post 0.99.18. (But not RFC 5082 GTSM.)
* | Bring "ex" version up to date with 0.99.18ex15pChris Hall2011-03-291-4/+3
| | | | | | | | | | | | | | | | | | Release: 0.99.18ex15p -- Pipework Branch Also fixes issue with unknown attributes -- does not release them prematurely. Contains the "bgpd: New show commands for improved view and address family support", which is post 0.99.18. (But not RFC 5082 GTSM.)

* Bring up to date with 0.99.16 releaseChris Hall2010-04-171-5/+5
| | | | | | | | | | This brings this branch up to date with 0.99.16, EXCEPT for the change to bgpd to use monotonic clock for timing updates. There are places where bgpd expects to find the actual time that things happened... so this change is not though to be complete. Further tidying in zebra, for FreeBSD.
* Compile all daemons, except vtysh, clean but with warnings.Chris Hall2010-04-161-1/+1
| | | | | | | | Now compiles with all daemons enabled. Split command.h to separate out the functions whish are only used durring command execution -- that is, those used in vty.c and family and in vtysh.
* New functions for error numbers and addresses in messages.Chris Hall2010-04-081-3/+3
| | | | | | | | Implemented less onerous ways of including descriptions of errors and IP addresses in logging and other messages. Implemented mapping of error numbers to error names, which is generally more meaningful.
* First beta releaseChris Hall2010-04-061-835/+1025
| | | | | | | Various bug fixes and improvements. Running with a fair amount of debug/assert code, which must be removed at some date.
* Major updateChris Hall2010-03-161-523/+860
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | bgpd/bgp_advertise.c bgpd/bgp_advertise.h The adj_in and adj_out objects are now put on a list based on the peer to whom the route belongs. The adj_in and adj_out objects also now point to the bgp_node which they are routes for. This substantially reduces the work needed to shut down a peer. bgpd/bgp_damp.c Changes to adj_in and adj_out forced small change to macros used in bgp_damp.c to manage its lists. bgpd/bgp_debug.c Replaced direct access to vty->node by the required vty_get_node(). bgpd/bgp_dump.c Changes to the names of fields in bgp_info structures. bgpd/bgp_engine.h Modified the debug and trace functions. bgpd/bgp_fsm.c Make use of sockunion2str() consistent with common usage. Improved some documentation. bgpd/bgp_main.c Use the newly extended qpn_add_hook_function() facility. bgpd/bgp_mplsvpn.c Changes to the names of fields in bgp_info structures. bgpd/bgp_msg_read.c Bug fix: correct handling of capability code length. Improvement: better casting in calculation of message length. bgpd/bgp_msg_write.c Bug fix: correct byte ordering of bgp_id in open message. bgpd/bgp_network.c Bug fix: correct handling of incoming connections. Takes advantage of improvements in sockunion.c. bgpd/bgp_nexthop.c Changes to the names of fields in bgp_info structures. bgpd/bgp_open_state.c Remove mistaken #include of memtypes.h bgpd/bgp_packet.c Improvements to handling of withdrawing routes for peers. bgpd/bgp_peer.c Tidying up the state of peers as they are enabled and disabled. Improvements to handling of withdrawing routes for peers. bgpd/bgp_peer.h Adding list bases for lists of routes originated by the peer. bgpd/bgp_peer_index.c Bug fix: correct freeing of peer indexes. bgpd/bgp_route.c Implement lists of bgp_info based in the owning peer. Adjust for name changes to bgp_info fields. Reimplemented all the clearing functions to use the lists of items that belong to the peer -- rather than searching route tables for stuff to withdraw. Changed work queue handling for added/changed routes, so that queues run through existing items, rather than having queues of auxiliary items -- lower memory overhead. bgpd/bgp_route.h Added fields to bgp_info to allow all bgp_info originated by each peer to live on lists based in the peer. And changed the name of existing fields to avoid confusion. bgpd/bgp_routemap.c Removing redundant code and fixing a memory leak. bgpd/bgp_table.h Based work queue for added/changed routes directly in the table, rather than having auxiliary structures. bgpd/bgp_vty.c Use vty_get_node() and vty_set_node() rather than direct access to the vty field. bgpd/bgpd.c Implement changes to route clearing. bgpd/bgpd.h Changes to work queue handling. lib/buffer.c Changes to allow embedded buffer structures. lib/buffer.h Moved struct buffer here so that could have embedded buffer structurs. lib/command.c Substantial tidy up and document exercise. Restructured the top level command processing and finding of descriptions and command completion. Removal of unpleasant messing around with the insides of vector structures. Movement of some command actions to vty.c. Uses uty.h to pick up the "private" functions from vty.c et al. lib/command.h Moved the "node" values to node_type.h, so that can use an enum node_type in places where cannot include command.h. lib/command_queue.c Updated to cope with the called command changing the node value. Improved handling of revoked commands, so the the command line handler does not get stuck waiting for a command to complete which has been revoked ! lib/command_queue.h Improved message format. lib/if.c Use vty_set_node(). lib/keychain.c Use vty_set_node(). new lib/keystroke.c new lib/keystroke.h New code to implement a keystroke FIFO. This moves some complexity out of the command handler. The handling of mixtures of escapes and Telnet IACs is tightened up. It would be possible to extend this to, say, UTF-8. Regularises the "stealing" of keystrokes for the "--more--" output handling... which was a bit hit and miss. new lib/list_util.c new lib/list_util.h New code to implement various forms of linked list, where the list pointers are embedded in structures. lib/log.c Changed the handling of log messages, so that all types of log output (except syslog) use the same message buffer scheme, and the message is constructed once and once only. Changes to the handling of VTY_LOCK() etc. Uses uty.h to pick up the "private" functions from vty.c et al. lib/log.h Changes to the buffering of log messages. new lib/mem_tracker.c New code to track memory allocation/deallocation, for debug purposes. lib/memory.c lib/memory.h Updated to allow the use of the mem_tracker. lib/memtypes.awk Made the memtypes into a named enum MTYPE. lib/memtypes.c Various new memory types. lib/mqueue.c lib/mqueue.h Add mqueue_finish function for close-down. lib/network.c lib/network.h Added non-blocking read_nb() and write_nb(). new lib/node_type.h As above. lib/plist.c Remove vty_puts() which wasn't a good idea. lib/qlib_init.c Added qps_init() to first stage and mqueue_finish to finish. lib/qpnexus.c lib/qpnexus.h More flexible hooks for in_thread_init and in_thread_final. lib/qpselect.c lib/qpselect.h Added qps_start_up() to build the required maps once and for all. Added qdebug to control the debug checks and validation. Improved validation and test functions. new lib/qstring.c new lib/qstring.h New code for limited flexible string handling. lib/qtimers.c Added qdebug to control the debug checks and validation. lib/routemap.c Use vty_set_node(). lib/sockunion.c lib/sockunion.h Tidied up and regularised the handling of sin_len and sin6_len. Created common function for setting port into socket. Created common function for initialisation/allocation of new sockunion. Reduced various functions by using common sub-functions. Rationalised some code. Added sockunion_listen() and sockunion_new_sockaddr(). Renamed sockunion_new() to sockunion_new_prefix(). Improved some logging messages. Added documentation. new lib/uty.h Functions etc. used only by vty/command/log/vty_io and vty_cli. lib/vector.c lib/vector.h Added vector_t type. Removed VECTOR_INDEX, vector_only_wrapper_free() and vector_only_index_free() -- following improvement of code in command.c. Added vector_set_min_length(), vector_set_new_min_length() and vector_length() functions. new lib/vio_fifo.c new lib/vio_fifo.h New code to manage simple FIFO of indefinite length. lib/vty.c lib/vty.h Reworked. Broken into vty.c, vty_io.c and vty_cli.c. new lib/vty_cli.c new lib/vty_cli.h CLI handling parts of the vty family. new lib/vty_io.c new lib/vty_io.h I/O parts of the vty family. lib/workqueue.h Introduced tyedefs for the various call-back entries. new tests/test-list_util.c Tests for the list-util stuff. vtysh/vtysh.c Small change to interface for cmd_execute_command()
* Fix "write file" command so reports "threaded". Working on Shutdown andpaulo2010-01-221-0/+3
| | | | | | HUP. Shutdown needs mechanism to know when bgp_engine has closed everything. HUP don't understand how it is supposed to cope with added/ deleted/retained peers and get them going again.
* Fixes to get 3 threads working. Fixes to get threaded command working.paulo2010-01-211-1/+9
| | | | | | Removed some of the temporary debuggery in qtimers that only worked in 1 thread. Initialised the mqueue mutex. Stopped peer_index from zeroizing its mutex after it had been initialized.

* Make logging (lib.c) and privileges (privs.c) pthread safepaulo2009-11-301-53/+56
| | | | | | | | | | | lib.c: use a mutex to protect all public methods. Replaced code in command.c etc that modified zlog_default directly with interlocked getters and setters. Requires that vty_log in vty.c handles its own pthread safety TBA. privs.c: use a mutex to protect all public methods. Counts RAISE and LOWER so that privilege stays RAISED until all pthreads have lowered. Improved messages in test-privs.c
* Upgrade lib/vector.c & .hChris Hall (GMCH)2009-11-241-95/+87
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This upgrade maintains the existing vector operations, but changes the underlying mechanisms. It then adds a number of new functions, extending the operations on vectors. The "struct vector" is redefined, which affects only some code in lib/command.c -- which pokes around inside what should be treated as a private data structure. Pro tem this is supported by a macro. The constant VECTOR_MIN_SIZE has been removed -- if there is a minimum size that should be enforced by the vector code. New functions include: vector_insert_item -- insert item, moving existing items vector_move_item -- move item from place to place in vector vector_delete_item -- delete item and close up gap vector_reverse -- reverse order of vector vector_push_item -- simple push vector_pop_item -- simple pop vector_insert -- insert 1 or more NULL items, moving existing items vector_delete -- delete 1 or more items and close up gap vector_bsearch -- perform binary search on vector vector_sort -- qsort vector vector_copy_here -- make copy of body of vector vector_move_here -- move body of vector vector_copy_append -- append copy of vector to end of another vector_move_append -- move body of vector to the end of another vector_copy_extract -- copy part of one vector to another vector_move_extract -- move part of one vector to another vector_copy_splice -- copy part of one vector to replace part of another, taking a copy of the replaced part vector_move_splice -- move part of one vector to replace part of another, taking a copy of the replaced part vector_copy_replace -- copy part of one vector to replace part of another vector_move_replace -- move part of one vector to replace part of another vector_discard -- discard body of vector vector_chop -- discard any unused memory in body of vector vector_decant -- decant vector to new body Other files affected: command.c: -- removal of VECTOR_MIN_SIZE -- use of vector_sort() -- use of VECTOR_INDEX to poke around inside vector (removing this is TODO) memtypes.c & memory.c -- updating names and comments for vectors vty.c -- removal of VECTOR_MIN_SIZE memory.h -- added SIZE(t,n) macro -- (sizeof(t) * (n))
* [bgpd] Stability fixes including bugs 397, 492Chris Caputo2009-07-191-10/+91
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I've spent the last several weeks working on stability fixes to bgpd. These patches fix all of the numerous crashes, assertion failures, memory leaks and memory stomping I could find. Valgrind was used extensively. Added new function bgp_exit() to help catch problems. If "debug bgp" is configured and bgpd exits with status of 0, statistics on remaining lib/memory.c allocations are printed to stderr. It is my hope that other developers will use this to stay on top of memory issues. Example questionable exit: bgpd: memstats: Current memory utilization in module LIB: bgpd: memstats: Link List : 6 bgpd: memstats: Link Node : 5 bgpd: memstats: Hash : 8 bgpd: memstats: Hash Bucket : 2 bgpd: memstats: Hash Index : 8 bgpd: memstats: Work queue : 3 bgpd: memstats: Work queue item : 2 bgpd: memstats: Work queue name string : 3 bgpd: memstats: Current memory utilization in module BGP: bgpd: memstats: BGP instance : 1 bgpd: memstats: BGP peer : 1 bgpd: memstats: BGP peer hostname : 1 bgpd: memstats: BGP attribute : 1 bgpd: memstats: BGP extra attributes : 1 bgpd: memstats: BGP aspath : 1 bgpd: memstats: BGP aspath str : 1 bgpd: memstats: BGP table : 24 bgpd: memstats: BGP node : 1 bgpd: memstats: BGP route : 1 bgpd: memstats: BGP synchronise : 8 bgpd: memstats: BGP Process queue : 1 bgpd: memstats: BGP node clear queue : 1 bgpd: memstats: NOTE: If configuration exists, utilization may be expected. Example clean exit: bgpd: memstats: No remaining tracked memory utilization. This patch fixes bug #397: "Invalid free in bgp_announce_check()". This patch fixes bug #492: "SIGBUS in bgpd/bgp_route.c: bgp_clear_route_node()". My apologies for not separating out these changes into individual patches. The complexity of doing so boggled what is left of my brain. I hope this is all still useful to the community. This code has been production tested, in non-route-server-client mode, on a linux 32-bit box and a 64-bit box. Release/reset functions, used by bgp_exit(), added to: bgpd/bgp_attr.c,h bgpd/bgp_community.c,h bgpd/bgp_dump.c,h bgpd/bgp_ecommunity.c,h bgpd/bgp_filter.c,h bgpd/bgp_nexthop.c,h bgpd/bgp_route.c,h lib/routemap.c,h File by file analysis: * bgpd/bgp_aspath.c: Prevent re-use of ashash after it is released. * bgpd/bgp_attr.c: #if removed uncalled cluster_dup(). * bgpd/bgp_clist.c,h: Allow community_list_terminate() to be called from bgp_exit(). * bgpd/bgp_filter.c: Fix aslist->name use without allocation check, and also fix memory leak. * bgpd/bgp_main.c: Created bgp_exit() exit routine. This function frees allocations made as part of bgpd initialization and, to some extent, configuration. If "debug bgp" is configured, memory stats are printed as described above. * bgpd/bgp_nexthop.c: zclient_new() already allocates stream for ibuf/obuf, so bgp_scan_init() shouldn't do it too. Also, made it so zlookup is global so bgp_exit() can use it. * bgpd/bgp_packet.c: bgp_capability_msg_parse() call to bgp_clear_route() adjusted to use new BGP_CLEAR_ROUTE_NORMAL flag. * bgpd/bgp_route.h: Correct reference counter "lock" to be signed. bgp_clear_route() now accepts a bgp_clear_route_type of either BGP_CLEAR_ROUTE_NORMAL or BGP_CLEAR_ROUTE_MY_RSCLIENT. * bgpd/bgp_route.c: - bgp_process_rsclient(): attr was being zero'ed and then bgp_attr_extra_free() was being called with it, even though it was never filled with valid data. - bgp_process_rsclient(): Make sure rsclient->group is not NULL before use. - bgp_processq_del(): Add call to bgp_table_unlock(). - bgp_process(): Add call to bgp_table_lock(). - bgp_update_rsclient(): memset clearing of new_attr not needed since declarationw with "= { 0 }" does it. memset was already commented out. - bgp_update_rsclient(): Fix screwed up misleading indentation. - bgp_withdraw_rsclient(): Fix screwed up misleading indentation. - bgp_clear_route_node(): Support BGP_CLEAR_ROUTE_MY_RSCLIENT. - bgp_clear_node_queue_del(): Add call to bgp_table_unlock() and also free struct bgp_clear_node_queue used for work item. - bgp_clear_node_complete(): Do peer_unlock() after BGP_EVENT_ADD() in case peer is released by peer_unlock() call. - bgp_clear_route_table(): Support BGP_CLEAR_ROUTE_MY_RSCLIENT. Use struct bgp_clear_node_queue to supply data to worker. Add call to bgp_table_lock(). - bgp_clear_route(): Add support for BGP_CLEAR_ROUTE_NORMAL or BGP_CLEAR_ROUTE_MY_RSCLIENT. - bgp_clear_route_all(): Use BGP_CLEAR_ROUTE_NORMAL. Bug 397 fixes: - bgp_default_originate() - bgp_announce_table() * bgpd/bgp_table.h: - struct bgp_table: Added reference count. Changed type of owner to be "struct peer *" rather than "void *". - struct bgp_node: Correct reference counter "lock" to be signed. * bgpd/bgp_table.c: - Added bgp_table reference counting. - bgp_table_free(): Fixed cleanup code. Call peer_unlock() on owner if set. - bgp_unlock_node(): Added assertion. - bgp_node_get(): Added call to bgp_lock_node() to code path that it was missing from. * bgpd/bgp_vty.c: - peer_rsclient_set_vty(): Call peer_lock() as part of peer assignment to owner. Handle failure gracefully. - peer_rsclient_unset_vty(): Add call to bgp_clear_route() with BGP_CLEAR_ROUTE_MY_RSCLIENT purpose. * bgpd/bgp_zebra.c: Made it so zclient is global so bgp_exit() can use it. * bgpd/bgpd.c: - peer_lock(): Allow to be called when status is "Deleted". - peer_deactivate(): Supply BGP_CLEAR_ROUTE_NORMAL purpose to bgp_clear_route() call. - peer_delete(): Common variable listnode pn. Fix bug in which rsclient was only dealt with if not part of a peer group. Call bgp_clear_route() for rsclient, if appropriate, and do so with BGP_CLEAR_ROUTE_MY_RSCLIENT purpose. - peer_group_get(): Use XSTRDUP() instead of strdup() for conf->host. - peer_group_bind(): Call bgp_clear_route() for rsclient, and do so with BGP_CLEAR_ROUTE_MY_RSCLIENT purpose. - bgp_create(): Use XSTRDUP() instead of strdup() for peer_self->host. - bgp_delete(): Delete peers before groups, rather than after. And then rather than deleting rsclients, verify that there are none at this point. - bgp_unlock(): Add assertion. - bgp_free(): Call bgp_table_finish() rather than doing XFREE() itself. * lib/command.c,h: Compiler warning fixes. Add cmd_terminate(). Fixed massive leak in install_element() in which cmd_make_descvec() was being called more than once for the same cmd->strvec/string/doc. * lib/log.c: Make closezlog() check fp before calling fclose(). * lib/memory.c: Catch when alloc count goes negative by using signed counts. Correct #endif comment. Add log_memstats_stderr(). * lib/memory.h: Add log_memstats_stderr(). * lib/thread.c: thread->funcname was being accessed in thread_call() after it had been freed. Rearranged things so that thread_call() frees funcname. Also made it so thread_master_free() cleans up cpu_record. * lib/vty.c,h: Use global command_cr. Add vty_terminate(). * lib/zclient.c,h: Re-enable zclient_free().
* [cleanup] Make command nodes staticStephen Hemminger2009-06-121-6/+6
| | | | | The cmd_nodes used to configure vty, can mostly be static so (basic data hiding 101).
* [vty] Add support for a 'restricted mode' with anonymous vty connectionsPaul Jakma2008-08-231-0/+20
| | | | | | | | | | | | | | | | | | | | * lib/command.h: Add a RESTRICTED_NODE, intended for use with anonymous, 'no login' vtys, to provide a subset of 'view' mode commands. * lib/command.c: Add RESTRICTED_NODE bits, nothing special, just following VIEW_NODE. * lib/vty.c: (vty_auth) enable authentication should fall back to restricted/view node as appropriate. (vty_create) init vty's to restricted/view node as appropriate, for the 'no login' case. (vty_{no_,}restricted_mode_cmd) config commands to enable 'anonymous restricted' in vty configuration. (vty_config_write) 'anonymous restricted' config. (vty_init) Install some commands to restricted mode, and the 'anonymous restricted' config commands into VTY_NODE. * bgpd/*.c: Install some of the safe(r) BGP commands into 'restricted mode', i.e. lookup commands of non-sensitive data. Useful with looking-glass route-servers.
* [logging] Add new "log timestamp precision" command for subsecond timestampsAndrew J. Schorr2007-04-281-0/+39
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 2007-04-28 Andrew J. Schorr <ajschorr@alumni.princeton.edu> * command.c: (config_write_host) Save "log timestamp precision" if not default value. (show_logging) Show configured timestamp precision. (config_log_timestamp_precision) Enable configuration of timestamp precision. (no_config_log_timestamp_precision) Restore default timestamp precision. (cmd_init) Install new timestamp precision commands. * log.h: (struct zlog) New timestamp_precision field. (quagga_timestamp) New function to generate a timestamp with the desired precision. (struct timestamp_control) Declare a structure for use in avoiding repeated duplicate calls to quagga_timestamp. * log.c: (quagga_timestamp) New function to generate a timestamp of the desired precision. (time_print) Call quagga_timestamp if the time hasn't already been calculated. (vzlog) Initialize a timestamp_control structure and pass it to time_print and vty_log. (zlog_backtrace) Fix 64-bit problem: cannot print size_t with %u. * vty.h: Must now include "log.h". (vty_log) Takes an additional struct timestamp_control argument. * vty.c: (vty_log_out) Use new struct timestamp_control and new quagga_timestamp function to print timestamps of the desired precision. (vty_time_print) Use new quagga_timestamp function. (vty_log) Accept new struct timestamp_control argument and pass it down to vty_log_out.
* [lib] Fix vector leak in error path in command.c, CID #38Paul Jakma2006-06-151-1/+3

| | | | | | | 2006-05-12 Paul Jakma <paul.jakma@sun.com> * command.c: (cmd_complete_command_real) Fix leak of cmd_vector in error case, Coverity CID #37.
* 2005-10-26 Paul Jakma <paul.jakma@sun.com>paul2005-10-261-62/+52
| | | | | | | | * command.c: Use MTYPE_HOST, MTYPE_STRVEC. Some other fixups, including fixing some likely leaks in config_write_file. * vty.c: memory macro usage fixes. (vty_read_config) fix leak where relative config file is specified.
* 2005-09-05 Paul Jakma <paul.jakma@sun.com>paul2005-09-051-3/+7
| | | | | | | * command.c: (install_element) be more robust. Eg, cmd_init need not have been called, some applications may use other library subsystems, which call install_element, without the application wanting commands and hence not calling cmd_init.
* 2005-08-22 Hugo Santos <hsantos@av.it.pt>paul2005-08-221-1/+4
| | | | | | | * command.h: (enum node_type) Add BGP_IPV6M_NODE * command.c: (node_parent) Handle BGP_IPV6M_NODE node (config_exit, config_end) ditto * vty.c: (vty_end_config) Handle BGP_IPV6M_NODE node
* 2005-05-06 Paul Jakma <paul@dishone.st>paul2005-05-061-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | * (general) extern and static'ification of functions in code and header. Cleanup any definitions with unspecified arguments. Add casts for callback assignments where the callback is defined, typically, as passing void *, but the function being assigned has some other pointer type defined as its argument, as gcc complains about casts from void * to X* via function arguments. Fix some old K&R style function argument definitions. Add noreturn gcc attribute to some functions, as appropriate. Add unused gcc attribute to some functions (eg ones meant to help while debugging) Add guard defines to headers which were missing them. * command.c: (install_node) add const qualifier, still doesnt shut up the warning though, because of the double pointer. (cmp_node) ditto * keychain.c: (key_str2time) Add GET_LONG_RANGE() macro, derived fromn vty.h ones to fix some of the (long) < 0 warnings. * thread.c: (various) use thread_empty (cpu_record_hash_key) should cast to uintptr_t, a stdint.h type * vty.h: Add VTY_GET_IPV4_ADDRESS and VTY_GET_IPV4_PREFIX so they removed from ospfd/ospf_vty.h * zebra.h: Move definition of ZEBRA_PORT to here, to remove dependence of lib on zebra/zserv.h
* 2005-04-25 Paul Jakma <paul.jakma@sun.com>paul2005-04-251-3/+6
| | | | | | | | | | * workqueue.{c,h}: Helper API for setting up and running queues via background threads. * command.c: install the 'show workqueues' command * memtypes.c: Add work queue mtypes, and a rib-queue type for a zebra rib work queue. * memtypes.h: Updated to match memtypes.c * Makefile.am: Add new workqueue files to build.
* 2005-03-14 Paul Jakma <paul.jakma@sun.com>paul2005-03-141-52/+52
| | | | | | | | | | * (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.
* 2005-03-14 Paul Jakma <paul.jakma@sun.com>paul2005-03-141-367/+367
| | | | * command.c: (various) Fix indentation and other whitespace.

| | | | | | | | | | | | | | | | | | | | | | * command.c: (sort_node) use vector_max instead of referencing (struct vector *)->max directly. Test that vector_max is > 0 before using it to calculate an index. Fixup vector loop to make main body conditional on vector slot not being empty. (cmd_cmdsize) Fixup vector loop to make main body conditional on vector slot not being empty. (cmd_filter_by_completion) ditto (cmd_filter_by_string) ditto (is_cmd_ambiguous) ditto (cmd_describe_command_real) Change index integers to unsigned. Test that vector_max is > 0 before using it to calculate an index. Return immediately with CMD_ERR_NO_MATCH if vline has no active slots. Fixup vector loop to make main body conditional on vector slot not being empty. (cmd_complete_command_real) ditto. (cmd_execute_command_strict) Fixup vector loop to be conditional on non-null slot.
* 2005-03-09 Paul Jakma <paul.jakma@sun.com>paul2005-03-091-2/+4
| | | | | * command.c: (config_list_cmd) Don't list hidden or deprecated commands, hiding these from tab completion is still to be done.
* 2005-03-09 Paul Jakma <paul.jakma@sun.com>paul2005-03-091-9/+7
| | | | | | * command.c: Undo commit of sign warning fix and hidden command in list_cmd. Sign warning is more subtle. list_cmd on its own will be committed after.
* 2005-03-08 Paul Jakma <paul.jakma@sun.com>paul2005-03-081-2/+3
| | | | | * command.c: (no_banner_motd_cmd) use XFREE. * vty.c: (vty_hello) fix the indentation and comment.

* 2005-03-08 Paul Jakma <paul.jakma@sun.com>paul2005-03-081-3/+5
| | | | | | | * command.c: (banner_motd_file_cmd) use XSTRDUP/XFREE * vty.c: (vty_hello) suggestions from Andrew, read by line and stub out trailling non-printable characters on each line thus allowing us to specify VTY_NEWLINE to vty_out.
* 2005-03-08 Jeroen Massar <jeroen@unfix.org>paul2005-03-081-2/+20
| | | | | | | | | | | * vty.c: (vty_hello) display motd file, if set * command.h: add char *motdfile to struct host * command.c: (config_write_host) write out motdfile config (banner_motd_file_cmd) new command, allow motd to be read from file. (no_banner_motd_cmd) free motdfile string, if needs be. (cmd_init) init (struct host).motdfile. Add new motd file commands.

| | | | | | | | | | | | to walk up in the node tree if called from vtysh. Different daemons might have commands with same syntax in different nodes (for example "router-id x.x.x.x" commands in zebra/ospfd/ospf6d daemons). * vtysh.c: Reflect changes in lib. cmd_execute_command() should know now that it's called from vtysh and must not attempt to walk up in the node tree.
