[jira] [Created] (ZOOKEEPER-2623) CheckVersion outside of Multi causes NullPointerException

[Diego Ongaro (JIRA)]

Diego Ongaro created ZOOKEEPER-2623:
---

 Summary: CheckVersion outside of Multi causes NullPointerException
 Key: ZOOKEEPER-2623
 URL: https://issues.apache.org/jira/browse/ZOOKEEPER-2623
 Project: ZooKeeper
  Issue Type: Bug
Reporter: Diego Ongaro
Priority: Minor


I wasn't sure if check version (opcode 13) was permitted outside of a multi op, 
so I tried it. My server crashed with a NullPointerException and became 
unusable until restarted. I guess it's not allowed, but perhaps the server 
should handle this more gracefully?

Here are the server logs:

And here's a one-liner to repro, which does a ConnectRequest followed by a 
{{CheckVersion(path="/", version=89235}}}:
{noformat}
echo 
LAAAJxAAABAAEQENAS8AAVyT
 | base64 --decode | nc localhost 2181 >/dev/null
{noformat}

This is against master as of a couple of weeks ago (f78061a). I haven't checked 
to see which versions are affected.

[jira] [Commented] (ZOOKEEPER-1045) Support Quorum Peer mutual authentication via SASL

[Michael Han (JIRA)]

[

 ] 

Michael Han commented on ZOOKEEPER-1045:


Update test report posted as https://goo.gl/qNR45M (open to everyone for 
comment). 

The gist out of the report is:
* We need to decide how to support shared Kerberos principals. Currently 
zkquo...@realm.com does not work, but it should be easy to fix this.
* There is a corner case about impersonating server (a server with a valid 
Kerberos credential from another server in ensemble.). My feeling is this is a 
corner case that we could either postpone or document - security wise it seems 
fine, because we support shared kerberos credential there is no way we can 
prevent impersonating (shared Kerberos credential is an extreme, as shared 
Kerberos credential effectively would disable authorization).

Re: QA github pre-commit queue

[Flavio Junqueira]

Yeah, I tried to trigger the 761 manually and it didn't work. I need to work on 
the manual trigger.

The issue with your PR 94 is likely to be a bug in the config that I think I 
fixed now. I need to create a test PR to debug it.

One problem is that builds.apache.org  is super 
slow, so it is difficult to work on the configuration right now. I'll work some 
more on my morning because it shouldn't be as busy.

Re: QA github pre-commit queue

[Michael Han]

I saw the pre-commit build from the new bot (
https://builds.apache.org/job/PreCommit-ZOOKEEPER-github-pr-build/1/) for
ZOOKEEPER-761. There are two issues:

* The test does not run, because "[exec] ZOOKEEPER-761 is not "Patch
Available".  Exiting."
* The build result was sent to dev list, but the result was not posted on
JIRA, as previous build bot did.

Still no sign of pre-commit build triggered by my PR94, btw.

Dear Community,we find a Vulnerability in Zookeeper/SOLR/Apache(PHP) about tcp connection exhausted,Waiting for your reply

[Linkezhang]

Problem:
In the client using some method (such as telnet) to establish a tcp connection 
with server-side apache listening port , but after the establishment of tcp 
connection, the client does not send any data. However, apache will not 
disconnect this tcp connection, may lead to the number of connections exhausted 
, Resulting in DOS

The attack process：
1. The client executes the telnet service port
[cid:image001.png@01D23070.DA903540]
Start the client telnet server port 6, do not exit for a long time:
Excuting an order:
telnet 172.22.17.26 6

Re: QA github pre-commit queue

[Benjamin Reed]

i also pushed a new version for
https://issues.apache.org/jira/browse/ZOOKEEPER-761 although that one might
be tricky since there are attached patches and a pr. should the pr still be
qaed?

QA github pre-commit queue

[Edward Ribeiro]

Dear community,

As part of the github move, we are still lacking the plumbing that allows
to run Jenkins CI tests, etc, on open Pull Requests. Please, take a look at
Kafka pending PR at Github to see what I am referring to.

Any committer could open an INFRA JIRA to address this?

Best regards,
Eddie

i think this is a class loading time problem,If ZooTrace.xxx()  has been used 
already before the application stopped, it can be loaded normally.

{code:java}
class SendThread extends Thread {
//..igonre   
@Override
public void run() {
  //..igonre

//*for example， If ZooTrace is called here, the problem 
does not occur.***
ZooTrace.logTraceMessage(LOG, ZooTrace.getTextTraceLevel(),
 "SendThread starting loop.");

while (state.isAlive()) {
//..igonre
//there is loop

}

//...executing

/***At this time, may be this web application instance has been 
stopped already.**/

   /**java.lang.IllegalStateException: Illegal access: this web application 
instance has been stopped already. Could not load 
[org.apache.zookeeper.server.ZooTrace]**/
//The container seems to think this is an illegal load
ZooTrace.logTraceMessage(LOG, ZooTrace.getTextTraceLevel(),
 "SendThread exitedloop.");
}

void close() {
state = States.CLOSED;
clientCnxnSocket.wakeupCnxn();
}

> When close() is called on the ZooKeeper instance from a ContextListener 
> (contextDestroyed) there is no way to synchronize with the fact that the 
> EventThread and SendThread have actually finished their work. The problem 
> lies in the SendThread which makes a call to ZooTrace when it exits, but that 
> class has not been loaded yet. Because the ContextListener could not 
> synchronize with the death of the threads the classloader has already 
> disappeared, resulting in a ClassNotFoundException.
> My personal opinion is that the close() method should probably wait until the 
> event and send thread have actually died.

[jira] [Commented] (ZOOKEEPER-1394) ClassNotFoundException on shutdown of client

Enrico Olivelli commented on ZOOKEEPER-1394:


I get regularly into this error. 
IMHO the problem is that the container closes  the Classloader and so no class 
can be loaded anymore.
Another fix is to make the client eagerly load the ZooTrace class by using it 
at boot or in other convenient place.
A workaround can be to use the ZooTrace class in the WebApplication and so 
force the classloader to load it

Flavio Junqueira commented on ZOOKEEPER-1394:
-

Let me elaborate. I understand that folks are getting it with Tomcat and JBoss, 
but why would the class not be found? Is it because it is not loading the 
server package? Would it make any difference if {{ZooTrace}} were in a 
different package?

It is not a big deal to remove that {{ZooTrace}} call because it is really the 
only call to {{ZooTrace}} in the client currently, but I'd rather understand 
why it happens and fix the problem rather than remove the call if possible. Do 
you understand why this happens, [~wuwen]n? I read the explanation in the 
description, but I don't understand why the class isn't being loaded. Granted 
that I don't understand Tomcat and JBoss well enough to determine whether it is 
problem with those frameworks.
