9527.0. "Using GDB crashed Unix V4.0B" by ALFSS2::DAU_G () Wed Apr 16 1997 16:50

    A customer uses "gdb" (gnu kernel debugger) on AS1000A or AS2100
    running Digital Unix V4.0B and the system crashed.
    
    He claimed that the enclosed code crashed the system also.
    
    Thanks for your help

    /* Running this program WILL CRASH your DU4.0B system.  You have
       been warned.  ;-)  It causes no problems under DU3.2C (or
       other revisions, I suspect).
    
       Since one of our users reported that ``gdb'' crashes DU4.0B,
       I've been working on reducing the reproduction of the problem
       to the smallest example (that hopefully doesn't require gdb).
       This little file seems to reproduce the gdb-induced crash
       identically.
    
       Note: I make no claims regarding gdb's logic; this file is merely
       a distillation of the steps that it goes through.

9527.1	pls provide crash information	GIDDAY::STRAUSS	talking through my binoculars	`Wed Apr 16 1997 18:00`	8
	Was the crash from "gdb" the same as for your code sample? What specific actions in gdb did the customer take to causse the system to crash? Is the problem reproducible? It would be useful if you could post the crash-data files. leon
9527.2	Known problem (if it's the one I know, at least!)	SMURF::PETERT	rigidly defined areas of doubt and uncertainty	`Wed Apr 16 1997 22:12`	34
	The problem is not with gdb or with the program provided. The program is actually a skeleton debugger, turning on ptrace which is what dbx, ladebug, and gdb had to do before procfs came along. The problem is the the 4.0b kernel. If the kernel has been built with KDEBUG configured, then any debugger used will crash the system. It has something to do with the integrated debugger, new with 4.0b, interfering with the graphic console. I forget the gruesome details, I just kept running into it all the time since I maintain dbx (with help). Reference QAR 50184 for more info, but there are a number of workarounds. Build your kernel without KDEBUG for one. Or, if you like things the way they are, go into superuser mode and run dbx on the kernel dbx -k /vmunix p db_enable /* should be 1 patch db_enable = 0 q And you're all set. Of course, if db_enable is NOT set to 1, then something else is going on and you should report it, but I'm pretty sure, given the brief description of the problem, that this is the problem. A patch is available - patch OSF410-046 (New id 26-00) to V4.0B There's also another workaround with sysconfigtab and saveterm, but I can't remember it offhand. Hope this helps. PeterT
9527.3	db_enable =0 and PATCH OSF410-046 applied	ALFSS2::DAU_G		`Thu Apr 17 1997 12:08`	711
	Thanks for the quick replies. Customer already tried to set "db_enable=0" and installed the OSF410-046 the system still crashed. Enclosed is the crash-data file.

	According to Canasta, this failure has been seen on V4.0 and V4.0B and I have just reproduced it on V4.0A. .0, you need to IPMT this for your customer.
9527.5	Use CANASTA ...	HAN::HALLE	Volker Halle MCS @HAO DTN 863-5216	`Sat Apr 19 1997 08:23`	7
	Giao, please read note 8919 on how to handle UNIX crash situations. The first step should ALWAYS be to obtain the crash-data.n file and send it to the CANASTA Mail Server. Volker.
9527.6	known/fixed	SMURF::DENHAM	Digital UNIX Kernel	`Sat Apr 19 1997 22:31`	12
	This is a known problem with a patch already in the latest support pools for V4.0 and later. But it will be a while yet before those patches are released. Please contact Sharon Reynolds ([email protected]) about getting an advance test patch to stop the crash. If she can't help, send me mail @ [email protected]. If this crash is as common as this note makes it sound, I wonder why I had one report of it only since v4.0 was released? I actually fixed this last fall. It's taken that long for the fix work its way through the system.
9527.7		SMURF::DENHAM	Digital UNIX Kernel	`Sat Apr 19 1997 22:33`	5
	I set .0 hidden, because it's a system crasher. The crash-data file that's posted should be a good enough clue as to whether the patch is needed. The panic is quite distinct. It only comes from ptrace, not /proc, and I've only seen gdb provoke it.
9527.8	a couple of those crashes have been seen in CANASTA	HAN::HALLE	Volker Halle MCS @HAO DTN 863-5216	`Sun Apr 20 1997 03:31`	48
	There are a couple of such crashes in CANASTA !

	Interesting. Well, when Canasta starts fixing the crashes, I'll be happy when it hears about the problems more than I do. Until then, I'm not happy having one mere report of this having reached me. I did give input to a CLD response last October. Maybe that stopped all further reports from showing up because it look like it was being fixed??
9527.10	CANASTA can do more ...	HAN::HALLE	Volker Halle MCS @HAO DTN 863-5216	`Mon Apr 21 1997 11:03`	23
	If you want, we can easily write a CANASTA rule for this problem and ask for everyone seeing this problem to raise an IPMT (or whatever you like...). CANASTA can also be used as an 'early warning tool' and a mechanism to transport troubleshooting information to the field or ask for more IPMTs, if a problem cannot be found/fixed due to insufficient crash information. Just send mail to CSC32::CANASTA (or talk to Ed Riopelle @ZKO) and we will write a CANASTA rule for you. We need an example of the crash-data file and information, that should be included in the CANASTA rule. You can also ALWAYS access the world-wide CANASTA crash data (see note SPECXN::CANASTA 239) to find out, if a certain crash footprint has been seen (in CANASTA) before. Any questions regarding CANASTA should be asked in SPECXN::CANASTA or by sending mail to HAN::HALLE ([email protected]). Volker. Volker.
9527.11	CANASTA could do even more...	RHETT::MOORE		`Mon Apr 21 1997 11:25`	11
	I think this illustrates the biggest problem in using CANASTA. Lots of cases are being added to the database (we in the Digital UNIX Support Group are routinely sending every crash-data we get) but very few rules are being added. So CANASTA may find matches on some cases, but it's often difficult or impossible to track down those other cases and find out the resolution, if any. It would be nice if there were some automated way to generate new rules as the result of IPMT/QAR closures. Martin
9527.12	need UNIX rule writers for CANASTA ...	HAN::HALLE	Volker Halle MCS @HAO DTN 863-5216	`Mon Apr 21 1997 14:18`	22
	Martin, I completely agree ! The CANASTA Mail Server is now being more widely used for sending UNIX crash-data files and it's quite good at spotting crashes with 'similar' footprints. But trying to find out, what's the status of those 'other' crashes/calls is the hard part ... We've tried to 'automate' getting the crash footprint data into CANASTA (and we currently capture all crash-data from IPMT calls, GURU:: and DECATL::), but what you're really interested in are 'solution' information (IPMT closures, released patches). CANASTA can currently only try to point you to the IPMT escalation numbers and then you're on your own... Writing rules is 'human resource' intensive and that's the problem. For OpenVMS we at least have about 3 people writing rules 'part time'. For UNIX, it's just one - from time-to-time - writing rules based on released patches. Try to address this through your management... Volker.
