[jira] [Commented] (ZOOKEEPER-2693) DOS attack on wchp/wchc four letter words (4lw)

Michael Han commented on ZOOKEEPER-2693:


The compatibility argument makes most of sense - so how about this:

* For both 3.5/3.4, provide a new configuration option that allow admin of 
ensemble to white list 4lw commands exposed to the world.
* If such an option is not provided in zoo.cfg ZK will choose a list of default 
commands in white list. Otherwise what's put in zoo.cfg will overwrite default 
values.

I think this is a good scoping that balances addressing this specific issue and 
ease of implementation.

Rate limiter and deprecating 4lw in favor of AdminServer (for 3.5) can be done 
as separate issues later (after 3.4.10 / 3.5.3 released).

bq. The configuration option of disabling 4lw or a subset of it seems an 
ultimate escape hatch

yes, this was my thought as well. 

Your argument around having the rate limiter makes sense, that's one of the 
things I was thinking about this morning when I originally recommended it. Now 
I'm also leaning toward the "whitelist" approach because I think it's a very 
clean solution to the problem. What I mean is no on/off config, just a single 
configuration listing the whitelisted 4lw. If the list is empty it's off (the 
map is empty), otw the user can select the commands they would like to expose. 

If we implement something for 3.4 the same b/w compat argument should hold. 
i.e. if we do rate limiting in 3.4 we should also have the same functionality 
in 3.5.

bq. Do you think we still need provide a middle ground for 4lws for 3.5 release 
/ master branch instead of completely shut it off?

Here's another way to think about this: we provide b/w compat when moving from 
X.Y.Z to X.Y+1.# As such we can deprecate 4lw in 3.5 (even turn it off by 
default), but we can't remove it entirely. If we want to provide a fix for this 
issue, and still maintain b/w compat in 3.5 then we should make it 
configurable. Does that make sense?

bq. I don't think we can go with an all/nothing approach, many users would 
still want to be able to monitor their system using existing 4lw based infra.
[~phunt] The current patch is for branch 3.5, where we have AdminServer, which 
is designed to replace four letter words. That is why the patch provides only 
an option to completely disable the entire four letter words instead of only 
disabling a specific subset. The AdminServer will make four letter words 
irrelevant and because AdminServer does not share the ZooKeeper client port 
(which sometimes have to be exposed publicly), admin of ensemble protected 
AdminServer port with firewall without interrupting ZooKeeper clients. Besides, 
this seems a good opportunity to push for deprecating four letter words in 
favor of AdminServer which is around for quite a while given the security 
concerns.

Michael Han commented on ZOOKEEPER-2693:


As for patch for branch-3.4, I am thinking instead of disabling a subset of 
commands, we could just add a rate limiter. All commands will still be 
available to use (including the wchp/wchc ones), but they are rate limited not 
to cause any damages. Disabling a sub set of commands does not solve the root 
issue, and I imagine it might still be possible to do DOS on servers acceptor 
threads by just utilizing white listed four letter words at massive scale on 
client side. 

The configuration option of disabling 4lw or a subset of it seems an ultimate 
escape hatch - I guess it does not hurt to provide both as option for users, 
but for branch-3.4 it looks like rate limiter is a must have to address current 
and potential issues when the server client port is accessible from public.

I looked at the patch. It is reasonable, but I don't think we can go with an 
all/nothing approach, many users would still want to be able to monitor their 
system using existing 4lw based infra, while mitigating the attack, and this 
doesn't allow any middle ground. 

How about on/off as you have in the current patch, but also allow a list of 
"whitelisted" 4lw - the default could be "ruok" and "srvr" or something of that 
nature. Notice we are building the list today here FourLetterCommands, and 
could build a list containing the configured whitelist instead? What do you 
think.

Patrick Hunt commented on ZOOKEEPER-2693:

Yes, effectively a rate limiter. However I was thinking in terms of number of 
4lw that we would allow to run concurrently, vs number of operations per 
second. This would address outliers - possibly very long running 4lw. "only let 
one 4lw run at a time, even it if takes 20 seconds".

Historically we've limited our dependency on other components. Neither 3.4 nor 
3.5 are pulling in guava today. One of the issues we've heard from users is 
that (component versioning issues in particular) complicates deployment. I 
think adding new dependencies to something like 3.4.10, ostensibly a fix 
release, would be unwise.

I threw the idea out there as a suggestion. We can take it or leave it for the 
various releases.

Michael Han commented on ZOOKEEPER-2693:


[~phunt] I think what you are talking to is to add rate limiting to 4lw / admin 
server. There are various schemes and trade offs for rate limiter 
implementation, and I'd prefer using a well tested one like the rate limiter 
from Guava if we are ok to pull in it as a dependency.

GitHub user hanm opened a pull request:

https://github.com/apache/zookeeper/pull/179

ZOOKEEPER-2693: DOS attack on wchp/wchc four letter words (4lw)

This is for master / branch-3.5:

* Introduce a new configuration option that by default turn off 4lw.
* Update docs that explicitly states ZooKeeper should not be deployed open 
to world for access and deprecating 4lw in favor of Jetty.

With these combined, the attack described in ZOOKEEPER-2693 is not possible 
if ZooKeeper is put behind a firewall where Jetty AdminServer is not publicly 
accessible.

Note for tests: I did not add any unit tests to test 4lw disabling because 
it is fairly obvious (though I have to update a place to prevent existing test 
broken, because we are using 4lw extensively to query test server states. We 
could query AdminServer instead but I consider that's a future work item - and 
even if we use AdminServer exclusively we can't dump 4lw completely because 
AdminServer test depends on 4lw - chicken egg problem.).

ZOOKEEPER-2696: Eclipse ant ask no longer determines correct classpath for 
tests after ZOOKEEPER-2689

After pulling branch-3.4 i noticed that I could no longer compile and run 
the tests within my IDE. 

The .classpath file generated by the eclipse ant task was missing necessary 
dependencies. These missing dependencies all appear to be transitive from 
dependencies brought in by ZOOKEEPER-2689 (which is why ant is able to run the 
tests). There were two possible ways to fix this, this patch explicitly lists 
the new transitive dependencies that are required by our test code. Another 
solution would be to remove `transitive="false"` from `` in the eclipse target 
of our `build.xml`. This solution would introduce even more transitive 
dependencies to the .classpath.

>Reporter: JiangJiafu

> 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.

> 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.

Github user eolivelli commented on the issue:

https://github.com/apache/zookeeper/pull/165
  
@eribeiro that you for reviewing this.
IMHO it it just a variable name. The script is basically the same as in the 
trunk version. I think it would be better to leave all versions as much similar 
as possible.
Eventually I can change this and file a pr against trunk too but I don't 
know the impact.
@fpj what do you think?

Re: Jenkins failing on pull request

[Michael Han]

The failure is expected because this PR is targeting branch-3.4 where the
triggers for pre-commit workflow is not ready.
https://github.com/apache/zookeeper/pull/165 is created to address that
issue. If anyone has time to review this that would be great.

Jenkins failing on pull request

[Yan Fitterer]

Hi, I submitted PR #166  a few 
days ago, but Jenkins seems to have had a blip  
on
 github PR build #288 (Target "qa-test-pullrequest" does not exist in the 
project "ZooKeeper”).

How should I proceed ? New PR ? Else can somebody kick the Jenkins build in 
that PR ? It looks to me like something went wrong with ant on that build 
attempt, but maybe I’m missing something.

> 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.

[jira] [Commented] (ZOOKEEPER-2693) DOS attack on wchp/wchc four letter words (4lw)

 ] 

Patrick Hunt commented on ZOOKEEPER-2693:
-

I had another thought on how to handle this - rather than on/off we could limit 
the number of 4lw that would be allowed to run in parallel. For example we 
could allow only a single 4lw to run at any one time. This would still provide 
the ability to run a 4lw, but with protection against overuse. It seems like 
this should be fairly simple to implement. Additionally we could provide this 
as an option (e.g. some folks might want to allow 5 to run in parallel). 
Regardless if we take this approach I think we would still want the on/off 
switches I already detailed.

> 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.

Hi Arshad,

I am curious where the IllegalArgumentException was thrown in code in your use 
case - I am asking because I spotted that in KeeperException.create, we have a 
default fall through [1] that throws IllegalArgumentException, and if this is 
not the place where you observed the IllegalArgumentException in your upgrade 
use case, then we may also need think to change the default fall through here 
from throwing IllegalArgumentException to return something like 
SystemErrorException, because it seems possible that unknown / not mapped error 
codes can be passed to KeeperException.create that will lead to 
IllegalArgumentException that client can't handle well?

[jira] [Created] (ZOOKEEPER-2695) Handle unknown error for rolling upgrade old client new server scenario

[Mohammad Arshad (JIRA)]

 Summary: Handle unknown error for rolling upgrade old client new 
server scenario
 Key: ZOOKEEPER-2695
 URL: https://issues.apache.org/jira/browse/ZOOKEEPER-2695
 Project: ZooKeeper
  Issue Type: Bug
  Components: java client
Reporter: Mohammad Arshad


In Zookeeper rolling upgrade scenario where server is new but client is old, 
when sever sends error code which is not understood by the client, client 
throws IllegalArgumentException. Generally IllegalArgumentException is not 
handled by any of the ZK applications. 

KeeperException.SystemErrorException should be thrown instead of 
IllegalArgumentException

> shutdown("Unexpected internal error");
> return;
> }
> {code}
