Re: (ITS#7085) mutex lockup issue

Hi Soichi, I was curious if you still encounter this issue using current OpenLDAP and back-mdb. I would note the back-bdb/hdb backends are now deprecated. It also occurred to me that the issue may have been related to lack of lock resources, etc (which are generally set in DB_CONFIG).

I've had a look whether I could reproduce the issue somehow and there is a potential crasher if the accesslog entry contained "reqmod: eduPersonAffiliation:+". Can you confirm whether you have entries like this in your logdb? There shouldn't be a way to have this kind of entry generated that I could see but processing one can sometimes cause a crash like the one you've been seeing. The following patch should fix an issue where an invalid accesslog entry of this sort is encountered. It should help you if that is the issue. ftp://ftp.openldap.org/incoming/Ondrej-Kuznik-20170327-ITS8609-ignore-inval… Regards, Ondrej

The remaining changes to syncrepl.c between 2.4.44 and current RE25 are: <http://www.openldap.org/its/index.cgi/?findid=8435> <http://www.openldap.org/its/index.cgi/?findid=8413> I would consider at least the patch for ITS#8413 as mandatory as well. Since ITS#8435 has been around since 2.4.40, it's unlikely to be related. <https://github.com/Zimbra/packages/blob/master/thirdparty/openldap/patches/…> is an easy spot to grab it from. --Quanah -- Quanah Gibson-Mount Product Architect Symas Corporation Packaged, certified, and supported LDAP solutions powered by OpenLDAP: <http://www.symas.com>

Hmm, I don't think you're hearing what I'm saying in its intended context. But let me table this for now. Can we back up to the other part of the thread? If you can point out what I'm missing with the VM clock reliability, that would help me better appreciate where you're coming from. For example, if we were talking about tests between multiple VMs, I could immediately appreciate the value of being generous with timing margins. But as I indicated in my other message, I'm having difficulty seeing how those kinds of problems could arise here. I apologize if there's something obvious I'm missing or if I'm coming across as belaboring an undesirable point. I'm just trying to make sure we don't inadvertently rule out a simple solution to the problem that could work for everyone. Thanks, -Kartik

In frame #5, syncrepl.c:2394 reads "rc =3D op->o_bd->be_add( op, &rs );" as per re24[0], but in your traceback, over_op_func calls overlay_op_walk with "which=3Dop_modify" (see frame #3) which doesn't really make sense to me.

It only requires that you set their values in whatever build script you use that issues the "make test" command. That is the whole reason why we defined these variables. -- -- Howard Chu CTO, Symas Corp. http://www.symas.com Director, Highland Sun http://highlandsun.com/hyc/ Chief Architect, OpenLDAP http://www.openldap.org/project/

Disclaimer: I did not dive into the test script. Maybe my suggestion is stupid. ;-) How about just setting the pwdChangedTime attribute (with the help of relax rules control) to a value in the (near?) past right before sending the bind request to be tested? Ciao, Michael.

I haven't come across this, [...] Hmm, the more I think about this, the harder it is for me to envision the kind of failure scenario you seem to be implying. Let me spell out my thought process and you can point out where I'm going wrong: Assumption: An "unstable" clock on a VM is one that doesn't advance at one second per second of real-world time, but at least monotonically increases over time (ignoring DST exceptions and rare things like that). If it's *not* monotonically increasing, then I don't see how all kinds of things wouldn't break on the system -- like cron running duplicate jobs, etc. OpenLDAP tests would be the least of someone's worries in that situation :-) Given this assumption, then "sleep 10" on a VM should always sleep for at *least* 10 seconds as marked by the VM's system clock. It doesn't matter how that compares to 10 seconds in the real world, since everything running on the VM is calculated relative to the VM clock. In particular, both the slapd process and the test shell script are relying on the same VM clock. So I don't see how sleeping for "1 second more than needed" -- which in this case would be 16 seconds and 31 seconds for each section -- could cause anything to break in this particular script. What am I missing? Thanks, -Kartik

This could well be a very good idea for broader reasons, but it probably would be less desirable as a sole solution for this particular situation, at least for my use case. In this case, I'm backporting 2.4.44 for zesty to 14.04 LTS. Ideally, I want this to be a clean rebuild, without any code changes. I'm especially reluctant to maintain a customized package for something that doesn't affect the behavior of the actual software. So having more variable(s) that need to be tuned, and thus changed from the vanilla Ubuntu package, isn't too appealing :-) Hopefully there's an agreeable solution to this issue that will make it work for everyone out of the box. In any case, I appreciate your and Howard's responses to this! Regards, -Kartik

Just to make sure we're understanding each other clearly -- are you saying that you've seen VMs where "sleep 10" won't sleep for at *least* 10 actual seconds? I haven't come across this, but if you have, then the adaptive solution where line 91 checks to see how many seconds have elapsed since line 67, and then calculates how much more it needs to sleep (perhaps with some more buffer) could be effective. If that doesn't work, then another thought might be to widen the difference between pwdLockoutDuration and pwdMaxAge to enable greater separation between the two tests, and adjust the script accordingly.

(ITS#8623) test022-ppolicy can fail due to timing dependency between lockout and expiration tests
by subbarao＠computer.org 22 Mar '17

22 Mar '17

Full_Name: Kartik Subbarao Version: 2.4.44 OS: Linux URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (108.52.86.252) A recent 2.4.44 package build failed on a VM due to the following timing dependency between the lockout and expiration tests in test022-ppolicy. The problem is that the password expiration time is 30 seconds, and on slower VMs, lines 67-91 take more than 30 seconds to execute. This causes the password to expire by the time the ldapsearch command on line 93 is executed. That ldapsearch command eats up one of the grace logins that's not supposed to be consumed until line 106. This causes the grep count on line 124 to be off, failing the entire script. A simple improvement would be to change line 91 to "sleep 10" instead of the current "sleep 20". This would buy 10 more seconds of leeway on slower VMs, while guaranteeing sufficient delay between lines 67-90 (e.g. 16 seconds, 1 second more than the 15 second lockout time) on fast VMs. A more robust improvement would be to check how much time has actually elapsed between lines 67-90 and change line 91 to only sleep until 16 total seconds have elapsed since line 67. Another suggestion would be to change the "sleep 20" on line 104 to "sleep 15". That will shave 5 seconds off the build time for everyone, while still guaranteeing that 31 seconds (e.g. 1 second more than the 30 second expiration time) will have elapsed between lines 67-106). A further optimization could be implemented, if desired, by revisiting the test and reducing all lockout times, expiration times, and other delays to the bare minimum necessary, which would speed up package build times across the board.

Hi Jordan, The ITS system is for reporting bugs, rather than asking for help with programming questions, etc. The correct place for such questions would be the openldap-technical mailing list: <http://www.openldap.org/lists/mm/listinfo/openldap-technical> This ITS will be closed.

I've moved this to the enhancement queue in case anyone ever wants to work on enforcing uniqueness across > 1 attribute, but I would think that would require all of the attributes to have the same syntax, etc. Michael's suggestion for this specific use case seems to be the best solution for now. --Quanah -- Quanah Gibson-Mount Product Architect Symas Corporation Packaged, certified, and supported LDAP solutions powered by OpenLDAP: <http://www.symas.com>

Re: (ITS#8619) Enhancement request: Nested group support using dynlist recursion

<html><head></head><body><div style="font-family: Verdana;font-size: 12.0px;"><div>I have encountered some scepticism regarding the benefits of nesting within OpenLDAP itself. Some have argued, that applications should resolve nested groups or that nested groups should be created using automation instead. Here, I'd like to respond to these two objections.</div> <div> </div> <div>1. applications should be responsible resolve nested groups</div> <div>First, I disagree from a philosophical point of view. The identity management system and thus the user directory is the central point of knowledge regarding group membership. For the sake of maintainability, all of the information as to why any given user is member of any of its groups, should be present at this central location. Whether a user is a direct member of a group or whether he is member of a sub-group, may interest applications, but what matters most, is that the user is in fact part of both the sub-group and all of its ancestors.</div> <div> </div> <div>Secondly, some applications simply don't have nested group support. It is a fairly common feature, but it just isn't part of every piece of software out there. Implementing nesting in the directory removes the need for support on the application side entirely. In the (from my curent point of view unlikely) event that some application demands to resolve nesting itself, aliasing can be used to deactivate dynlist for the given application.</div> <div> </div> <div>2. automation instead of nesting</div> <div>Automation comes with two caveats which I would like to address individually:</div> <div> </div> <div> <div>2.a additional software</div> <div>This may come as a no brainer for most, but I'd like to point out that automation requires some form of additional software, be it diy scripts or an application. This increases complexity both due to operation of this software and its interaction with the user directory.</div> <div> </div> </div> <div>2.b divergent center of information</div> <div>Instead of maintaining nesting information within the user directory, the software used most likely stores its data outside of the directory. Worst case, it is hardcoded into some scripts. Thus, the information as to which groups are related is likely stored outside of the actual directory itself. This point may be void if the automation system stores nesting information on the group objects inside of the user directory.<br/>  </div> <div>Sincerely,</div> <div>Christopher Klinge</div></div></body></html>

Now I enabled rewrite and build fail :-/ server/slapd/syncrepl.c define variables named 'bv2' that are used if rewrite is enabled and unused otherwise. Maybe the definition of 'REWRITE_DN' ( server/slapd/syncrepl.c, ~line 1726 ) could declare bv2 as unused to avoid a compiler warning. uploaded a new version: ftp://ftp.openldap.org/incoming/andreas-schulze-its8578-20170319.patch Andreas
