> The QuorumPeer$QuorumServer.recreateSocketAddress()  is used to resolved the 
> hostname to a new IP address(InetAddress) when any exception happens to the 
> socket. It will be very useful when a hostname can be resolved to more than 
> one IP address.
> But the problem is Java API InetAddress.getByName(String hostname) will 
> always return the first IP address when the hostname can be resolved to more 
> than one IP address, and the first IP address may be unreachable forever. For 
> example, if a machine has two network interfaces: eth0, eth1, say eth0 has 
> ip1, eth1 has ip2, the relationship between hostname and the IP addresses is 
> set in /etc/hosts. When I "close" the eth0 by command "ifdown eth0", the 
> InetAddress.getByName(String hostname)  will still return ip1, which is 
> unreachable forever.
> So I think it will be better to check the IP address by 
> InetAddress.isReachable(long) and choose the reachable IP address.

 ] 

Michael Han commented on ZOOKEEPER-2693:


One option is to enable TLS for ZooKeeper client-server communication. Because 
TLS is on a different port (secureClientPort) than the four letter words port 
(clientPort), we can then put clientPort behind a firewall which effectively 
makes only admin (or whoever that's trusted) can execute four letter words.

This however does not address the issues completely, because TLS is only 
supported since ZooKeeper 3.5.1 so it would not work for 3.4.x. Also even with 
TLS presence, it might still be possible that a ZooKeeper ensemble is attacked 
as long as the ensemble is open to the world: we don't have rate limiting built 
in, so if a set of rogue clients making connection requests, when in large 
scale, could possibly keep ensemble too busy to serve other requests. Although 
we do have IP based authentication scheme we don't have any rate limiters 
implemented to enforce accesses in such case.

I believe the original design consideration for ZooKeeper was that ZooKeeper 
ensembles should only be accessible from a trusted computing environment 
instead of opening to the world. This design decision made perfect sense in the 
Hadoop context but might not be ideal given today's thread models (e.g., it is 
never safe to trust any network communication, attackers exist inside the 
corporate network, and so on.). As such, we may need to change the assumption 
on where ZooKeeper is going to be deployed and operated, but before that, to 
address this specific issue documented in the JIRA, we could do a combination 
of:

* As Patrick suggested, add configurations options to turn off four letter 
words and / or specific commands.
* Document explicitly the recommended security practice on deploy and operate 
ZooKeeper - basically admin should not leave the ZK wide open to the world.

I think a patch contain both should be enough for resolving the current issue.

In long term, we need reevaluate the design decisions and security thread 
models and to bridge the gap between the current design and what ZooKeeper is 
actually used in prod today (e.g. adding rate limiter, enforced access control, 
not just for TLS but also for Kerberos, like what ZOOKEEPER-1634 is trying to 
solve.).

ZooKeeper DOS exploit published

[Patrick Hunt]

Hi folks. The following exploit was recently published on the web and has
come to our attention, it details a ZooKeeper DOS attack against certain
four letter words (4lw), possible when the client port is exposed to
untrusted actors:

https://webcache.googleusercontent.com/search?q=cache:_CNGIz10PRYJ:https://
www.exploit-db.com/exploits/41277/+=14=en=clnk=us

Typically we address security issues on the security@ private mailing list,
publishing a fixed release before publicly releasing the exploit, however
in this case given the information is publicly available already we decided
there's little point to keeping it on security@ exclusively.
http://zookeeper.apache.org/security.html

A JIRA has been created to track this issue:
https://issues.apache.org/jira/browse/ZOOKEEPER-2693
we expect to include a patch to address in 3.4.10 and 3.5.3.

Patrick Hunt commented on ZOOKEEPER-2693:
-

A simple patch would provide a configuration option that disables these 4lw by 
default. We should include this in 3.4/3/5 code lines. Additionally in 3.5 
Jetty metrics support was added, replacing the legacy 4lw. In 3.5.3 and later 
we should disable 4lw entirely (through a second config option) and encourage 
people to use Jetty instead.

 Summary: DOS attack on wchp/wchc four letter words (4lw)
 Key: ZOOKEEPER-2693
 URL: https://issues.apache.org/jira/browse/ZOOKEEPER-2693
 Project: ZooKeeper
  Issue Type: Bug
  Components: security, server
Affects Versions: 3.4.0
Reporter: Patrick Hunt
Priority: Blocker
 Fix For: 3.4.10, 3.5.3


The wchp/wchc four letter words can be exploited in a DOS attack on the ZK 
client port - typically 2181. The following POC attack was recently published 
on the web:

https://webcache.googleusercontent.com/search?q=cache:_CNGIz10PRYJ:https://www.exploit-db.com/exploits/41277/+=14=en=clnk=us

The most straightforward way to block this attack is to not allow access to the 
client port to non-trusted clients - i.e. firewall the ZooKeeper service and 
only allow access to trusted applications using it for coordination.

>Reporter: JiangJiafu
>Priority: Minor

> The QuorumPeer$QuorumServer.recreateSocketAddress()  is used to resolved the 
> hostname to a new IP address(InetAddress) when any exception happens to the 
> socket. It will be very useful when a hostname can be resolved to more than 
> one IP address.
> But the problem is Java API InetAddress.getByName(String hostname) will 
> always return the first IP address when the hostname can be resolved to more 
> than one IP address, and the first IP address may be unreachable forever. For 
> example, if a machine has two network interfaces: eth0, eth1, say eth0 has 
> ip1, eth1 has ip2, the relationship between hostname and the IP addresses is 
> set in /etc/hosts. When I "close" the eth0 by command "ifdown eth0", the 
> InetAddress.getByName(String hostname)  will still return ip1, which is 
> unreachable forever.
> So I think it will be better to check the IP address by 
> InetAddress.isReachable(long) and choose the reachable IP address. 
> I have modified the ZooKeeper source code, and test the new code in my own 
> environment, and it can work very well when I turn down some network 
> interfaces using "ifdown" command.
> The original code is:
> {code:title=QuorumPeer.java|borderStyle=solid}
> public void recreateSocketAddresses() {
> InetAddress address = null;
> try {
> address = InetAddress.getByName(this.hostname);
> LOG.info("Resolved hostname: {} to address: {}",

Instead of hardcoding 2000 here, we can have a constant variable represent 
the timeout value at the beginning of QuorumPeer.java. 
[QuorumCnxManager](https://github.com/apache/zookeeper/blob/master/src/java/main/org/apache/zookeeper/server/quorum/QuorumCnxManager.java)

> ZooKeeper3.4.8
>Reporter: JiangJiafu
>Priority: Minor
>
> The QuorumPeer$QuorumServer.recreateSocketAddress()  is used to resolved the 
> hostname to a new IP address(InetAddress) when any exception happens to the 
> socket. It will be very useful when a hostname can be resolved to more than 
> one IP address.
> But the problem is Java API InetAddress.getByName(String hostname) will 
> always return the first IP address when the hostname can be resolved to more 
> than one IP address, and the first IP address may be unreachable forever. For 
> example, if a machine has two network interfaces: eth0, eth1, say eth0 has 
> ip1, eth1 has ip2, the relationship between hostname and the IP addresses is 
> set in /etc/hosts. When I "close" the eth0 by command "ifdown eth0", the 
> InetAddress.getByName(String hostname)  will still return ip1, which is 
> unreachable forever.
> So I think it will be better to check the IP address by 
> InetAddress.isReachable(long) and choose the reachable IP address. 
> I have modified the ZooKeeper source code, and test the new code in my own 
> environment, and it can work very well when I turn down some network 
> interfaces using "ifdown" command.

> Add pagination support to the getChildren() call, allowing clients to iterate 
> over children N at the time.
> Motivations for this include:
>   - Getting out of a situation where so many children were created that 
> listing them exceeded the network buffer sizes (making it impossible to 
> recover by deleting)[1]
>  - More efficient traversal of nodes with large number of children [2]
> I do have a patch (for 3.4.6) we've been using successfully for a while, but 
> I suspect much more work is needed for this to be accepted.

Thanks [~hanm] for review. 
Old leader is already in QuorumStats.Provider.LEADING_STATE that is why I think 
it is not good to include in the assert list.

As far as I can infer, the current Jenkins errors (below) is because `ant` 
was compiled on JDK8 and run on JDK7.

@rakeshadr If it makes you feel any better we have been running with an 
older version of this patch in production for a while.  We have used it as part 
of a rolling upgrade at least 10 times in production where if it were not there 
we would have had some very painful outages. 

I have also manually tested it at least 50 times shooting the leader under 
load (10,000 operations/second) on a 3.4 GB DB, watching it recover, and then 
validating the integrity of the DB to be sure we didn't get any corruption.

> I know this is long but please here me out.
> I recently inherited a massive zookeeper ensemble.  The snapshot is 3.4 GB on 
> disk.  Because of its massive size we have been running into a number of 
> issues. There are lots of problems that we hope to fix with tuning GC etc, 
> but the big one right now that is blocking us making a lot of progress on the 
> rest of them is that when we lose a quorum because the leader left, for what 
> ever reason, it can take well over 5 mins for a new quorum to be established. 
>  So we cannot tune the leader without risking downtime.
> We traced down where the time was being spent and found that each server was 
> clearing the database so it would be read back in again before leader 
> election even started.  Then as part of the sync phase each server will write 
> out a snapshot to checkpoint the progress it made as part of the sync.
> I will be putting up a patch shortly with some proposed changes in it.
