2003-01-18This patch adds Yon's CLI 'walk back up tree' patch. Following are emailpaul
describing original patch and a shorter email describing changes to an updated patch, the one which is applied: From havanna_moon@gmx.net Sat Jan 18 00:37:13 2003 Date: Mon, 9 Dec 2002 05:32:58 +0100 (CET) From: Yon Uriarte <havanna_moon@gmx.net> To: "the list(tm) Zebra" <zebra@zebra.org> Subject: [zebra 16671] [PATCH] CLI extensions. Hi, this patch adds 2 improvements to the CLI (lib/command.c): #1) When in subconfig mode (router XXX, interface XXX, ...) commands that fail for that node are tried on the main CONFIG_NODE. This is great for configuring interfaces or changing the sub-config mode quickly, without the need to type 'exit' between commands: ospfd(config)# int eth1 ospfd(config-if)# ip ospf cost 9 ospfd(config-if)# ip ospf prio 101 ospfd(config-if)# router ospf ospfd(config-router)# network 1.1.1.0/24 area 51 ospfd(config-router)# int eth2 ospfd(config-if)# ip ospf authentication message-digest ospfd(config-if)# ^Z ospfd# Is this IOS-like or does IOS try to walk up the tree of config sub-modes instead of directly trying the command on CONFIG_NODE? CAVEATS: "?" and "TAB" don't work. IIRC IOS doesnt show that help neither. NON-CAVEATS: This wont break much, as config_from_file() already does try a failed command on the parent node of the actual vty->node. If changing the code to walk the node tree instead of directly trying the command on the ENABLE_NODE the same semantics would be in use and no future bugs could creep in. #2) When in config or subconfig mode use the "do " prefix to execute commans of the ENABLE_NODE. "?" and "TAB" work. The space after the "do" is needed: ospfd(config-router)# do<?> % There is no matched command. ospfd(config-router)# do <?> clear Reset functions configure Configuration from vty interface copy Copy configuration debug Debugging functions (see also 'undebug') disable Turn off privileged mode command end End current mode and change to enable mode. exit Exit current mode and down to previous mode help Description of the interactive help system list Print command list no Negate a command or set its defaults quit Exit current mode and down to previous mode show Show running system information terminal Set terminal line parameters who Display who is on vty write Write running configuration to memory, network, or terminal ospfd(config-router)# do sho<TAB> ospfd(config-router)# do show me<TAB> ospfd(config-router)# do show memory r<TAB> ospfd(config-router)# do show memory rip RIP structure : 0 RIP route info : 0 RIP interface : 0 RIP peer : 0 RIP offset list : 0 RIP distance : 0 ospfd(config-router)# ^Z ospfd# CAVEATS: I don't have access to an IOS with this feature, so I implemented it from the comments on this mailing list (in fact my personal motivation was to implement feature #1, which I missed on zebra.

I will happily change this patch to mimick IOS or the mailing-list consensus on CLI-usability. regards, yon From havanna_moon@gmx.net Sat Jan 18 01:13:11 2003 Date: Sat, 11 Jan 2003 23:36:51 +0100 (CET) From: Yon Uriarte <havanna_moon@gmx.net> To: zebra@zebra.org Subject: [zebra 17218] Re: [PATCH] CLI extensions. Hi, [redacted] > I prefer the IOS way for the node "up walking". This patch should walk the tree upwards: bgpd(config)# router bgp 1 bgpd(config-router)# address-family ipv4 multicast bgpd(config-router-af)# access-list 1 remark hola que tal bgpd(config)# I cant test all combinations, so I cant rule out some bugs.

From: Masahiko Endo <endo@suri.co.jp> Reply-To: zebra@zebra.org To: zebra@zebra.org Cc: kunihiro@zebra.org, yokota@kddlabs.co.jp Subject: [zebra 16823] [PATCH] Bugfix and new feature in Opaque-LSA handling. ----- * ----- * ----- * ----- * ----- * ----- * ----- * ----- * ----- * ----- Changes 2002.12.20 1. Bug fixes 1.1 When an opaque LSA is being removed from (or added to) the LSDB, it does not mean a change in network topology. Therefore, SPF recalculation should not be triggered in that case. There was an assertion failure problem "assert (rn && rn->info)" inside the function "ospf_ase_incremental_update()", because the upper function "ospf_lsa_maxage_walker_remover()" called it when a type-11 opaque LSA is removed due to MaxAge. 1.2 Type-9 LSA is defined to have "link-local" flooding scope. In the Database exchange procedure with a new neighbor, a type-9 LSA was added in the database summary of a DD message, even if the link is different from the one that have bound to. 2. Feature enhancements 2.1 Though a "wildcard" concept to handle type-9/10/11 LSAs altogether has introduced about a year ago, it was only a symbol definition and actual handling mechanism was not implemented. Now it works.

Date: Fri, 20 Dec 2002 17:58:43 +0900 From: Masahiko Endo <endo@suri.co.jp> Reply-To: zebra@zebra.org To: zebra@zebra.org Cc: kunihiro@zebra.org Subject: [zebra 16824] [PATCH] nsm_kill_neighbor [ The following text is in the "ISO-2022-JP" character set. ] [ Your display is set for the "ISO-8859-1" character set. ] [ Some characters may be displayed incorrectly. ] Hi Ishiguro-san, Here is my problem analysis against the case that the ospfd crashes when an interface is brought down. When the ospfd receives a ZEBRA message "ZEBRA_INTERFACE_DOWN" from zebra daemon, the ospfd performs bunch of ospf-interface cleanup for the notified zebra-interface. There are cases that neighbor instance "nbr", which will be removed afterward, may scheduled in the NSM thread event queue. And when the NSM event thread is fired, dereference for this already freed "nbr" pointer causes SIGSEGV. Please take a look at following timeline of processing sequences.

Date: Sat, 11 Jan 2003 23:26:28 +0100 (CET) From: Yon Uriarte <havanna_moon@gmx.net> To: "the list(tm) Zebra" <zebra@zebra.org> Subject: [zebra 17217] [PATCH] show thread CPU Hi, a little patch from the 'stupid preprocessor tricks' collection to record thread statistics. Usage: "show thread cpu [r][w][t][e][x]" Output Fields: self explaining I hope. Type is one of RWTEX for: Read, Write (fd threads), Timer, Event, Execute. Overhead vs. vanilla zebra: almost nothing. Vanilla CVS zebra already collects thread run times. Caveats: Under linux getrusage has a granularity of 10ms, which is almost useless in this case. Run ./configure, edit config.h and comment out "#define HAVE_RUSAGE", this way it will use getimeofday which has a much better granularity. IMHO this is better, as cooperative threads are effectively running during all that wall time (dont care if CPU utilization was 3% or 99% during the time the thread was running (an effective rusage combined with getimeofday could give that info)). Maybe someone can give tips for other platforms on API granularity. TODO: change some of the calls to thread_add_$KIND to funcname_thread_add_$KIND with a meaningfull funcname, so users will get a better idea of what's going on. F.ex. (AFAIK): ospf_spf_calculate_timer -> "Routes Step 1, areas SPF" ospf_ase_calculate_timer -> "Routes Step 2, externals" Could this be added to the unofficial patch collection? Could someone with BGP keepalive problems run their bgpd with this patch and post the results?
