Thanks for the patch, it is a good improvement on doc.

I think the ID here refers to the id of the scheme:id pair of the ID object 
in the ACL, correct? Mentioning this because the auth scheme is also referenced 
in command line where people can do 'setAcl /node auth:username:password:crdwa' 
in which case the username (sometimes overloaded as id) is required.

Hi Abe,

I have attempted to work on providing the same support last year for branch-3.5 
and I have created the pull request for what I have so far for you to look at: 
https://github.com/apache/zookeeper/pull/185
Readme: https://github.com/geek101/zookeeper/blob/branch-3.4/README_SSL.md 

I definitely did not consider upgrading non SSL cluster to an SSL one for ZAB 
and FLE, glad that you brought that up. 

I am attempting to combine these changes and Netty changes I have for Trunk. 
You can find them here:
https://github.com/geek101/zookeeper/pull/6

Let me know what you think.
thanks
Powell.

[geek101]

GitHub user geek101 opened a pull request:

https://github.com/apache/zookeeper/pull/185

Branch 3.5 FLE and ZAB SSL socket support [DO NOT MERGE]

# Zookeeper Dynamic Quorum SSL (work in progress)

Provides SSL for Leader Election and ZAB i.e ports 3888 and 2888.

Goal of this patch is to build on top of SSL changes for 
[branch-3.4](https://github.com/geek101/zookeeper/blob/branch-3.4/README_SSL.md)
 and in 
the spirit of branch-3.5 provide support for dynamic reconfiguration, i.e 
do 
not violate safety and liveliness even when SSL is enabled.

### TODO

* CA based cert verification currently has no support for changing CA in a 
fault-tolerant way. Alternative to changing CA is to revoke the quorum peer 
to be removed via CRL(s) hence this needs more discussion/debate perhaps. 

* Needs test framework and/or test cases to verify new functionality, this 
is 
probably a significant amount of work gating this patch among other things.

### Self Signed Certs How To

The idea here is to propagate the new member(s) certificate fingerprint(s) 
via the secure channel to the quorum via the reconfig() API.

Each quorum peer will have its self-signed cert finger print (typically 
like 
a SHA-256 digest) embedded into its server string.

```
server.1=125.23.63.23:2780:2783:participant:cert:SHA-256-;2791
```

We also have support for both plain and secure port for ZookeeperServer 
hence 
the config has been extended to reflect that as follows.

```
server.1=125.23.63.23:2780:2783:participant:cert:SHA-256-;plain:2791;
secure:2891
```

A reconfiguration operation would work by submitting the new server 
config (or the new quorum list) to reconfig() API.

This has been tested to work with the current state of the patch.

### Some details

* 
[X509Util](https://github.com/geek101/zookeeper/blob/branch-3.5-ssl-review5/src/java/main/org/apache/zookeeper/common/X509Util.java)
 
becomes first class citizen and 
[QuorumX509Util](https://github.com/geek101/zookeeper/blob/branch-3.5-ssl-review5/src/java/main/org/apache/zookeeper/server/quorum/util/QuorumX509Util.java)
 and 
[ServerX509Util](https://github.com/geek101/zookeeper/blob/branch-3.5-ssl-review5/src/java/main/org/apache/zookeeper/server/util/ServerX509Util.java)
extend it.
* 
[ZKConfig](https://github.com/geek101/zookeeper/blob/branch-3.5-ssl-review5/src/java/main/org/apache/zookeeper/common/ZKConfig.java)
 
becomes an abstract class and 
[QuorumSslConfig](https://github.com/geek101/zookeeper/blob/branch-3.5-ssl-review5/src/java/main/org/apache/zookeeper/server/quorum/QuorumPeerConfig.java)
 and 

[ZookeeperServerConfig](https://github.com/geek101/zookeeper/blob/branch-3.5-ssl-review5/src/java/main/org/apache/zookeeper/server/ZookeeperServerConfig.java)
 implement it.
* 
[QuorumServer](https://github.com/geek101/zookeeper/blob/branch-3.5-ssl-review5/src/java/main/org/apache/zookeeper/server/quorum/QuorumPeer.java#L278)
 gets the parsing code for the extra cert information and gets 
help from new 
[SSLCertCfg](https://github.com/geek101/zookeeper/blob/branch-3.5-ssl-review5/src/java/main/org/apache/zookeeper/SSLCertCfg.java)
 class. Dynamic config generation is handled 
transparently due to this.
* 
[ZKDynamicX509TrustManager](https://github.com/geek101/zookeeper/blob/branch-3.5-ssl-review5/src/java/main/org/apache/zookeeper/server/quorum/util/ZKDynamicX509TrustManager.java)
 handles the dynamic verification of certs and 
gets help from QuorumPeer's new API, 

[getQuorumServerFingerPrintByElectionAddress()](https://github.com/geek101/zookeeper/blob/branch-3.5-ssl-review5/src/java/main/org/apache/zookeeper/server/quorum/QuorumPeer.java#L1642)
 and 

[getQuorumServerFingerPrintByCert()](https://github.com/geek101/zookeeper/blob/branch-3.5-ssl-review5/src/java/main/org/apache/zookeeper/server/quorum/QuorumPeer.java#L1661)
* Support for a Quorum peer to also be authenticated as a [ZK 
client](https://github.com/geek101/zookeeper/blob/branch-3.5-ssl-review5/src/java/main/org/apache/zookeeper/server/util/ServerX509Util.java#L62)
 (this 
will be removed if it breaks security and or is not needed)

ZOOKEEPER-236: SSL Support for Atomic Broadcast protocol [DO NOT MERGE]

This is a work in progress, I wanted to get some feedback from the 
community while I worked on this. Please do not merge yet. Tests, 
documentation, and some cleanup still coming. 

This is a first pass at ssl support for the zookeeper quorum. It supports 
encrypting both leader election and normal operation.

Rolling upgrades are supported via port unification 
(`portUnification=true`). This should only be used while performing a rolling 
upgrade.

Some open questions:
- Anyone have any ideas for better names for the configuration options 
(`sslQuorum` and `portUnification` currently).
- I am using the same configuration that points to the truststore/keystore 
used for server <-> client ssl. Do they need to be separate?
- Is port unification the correct approach for rolling upgrades? Is the 
impact from the use of `BufferedSocket`s during the upgrade acceptable? See: 
http://stackoverflow.com/questions/25637039/detecting-ssl-connection-and-converting-socket-to-sslsocket
 
http://stackoverflow.com/questions/6559859/is-it-possible-to-change-plain-socket-to-sslsocket
- server <-> client ssl is implemented with netty. I did not feel that 
rewriting our server <-> server logic with netty was necessary given how easy 
ssl was to implement with standard java `SSLSocket`s. Any arguments to the 
contrary?

Thanks,
Abe

Apache ZooKeeper 3.5.3-beta Release Plan

[Michael Han]

Hi all,

We all know that a stable 3.5 release is long awaited by community.
Previously we were on hold because of a security related issue
 around dynamic
reconfiguration and most recently a CVE
 around four letter
words. Now with both issues resolved in branch-3.5, I think we are ready to
move forward with 3.5.3 beta release and hopefully in near future, ship the
stable 3.5 release after this. So I am taking a stab here to start the
discussion on the plan of moving 3.5.3-beta forward.

Currently there are  six blocker issues

targeting 3.5.3:
ZOOKEEPER-2693 :
already resolved for branch-3.5.  The issue is still open because of
remaining work for branch-3.4.
ZOOKEEPER-761 :
already resolved for branch-3.5. The issue is still open because of some
potential changes required for branch-3.4.

As for the remaining issues marked as blocker, I'd like to propose we push
them to next release because these issues are not regressions - unless we
think some of them are absolutely required to get resolved for 3.5.3.
ZOOKEEPER-2317 
ZOOKEEPER-2159 
ZOOKEEPER-1549 
ZOOKEEPER-1159 

I will start doing the work to defer all JIRA issues targeting 3.5.3 to
3.5.4 by end of this week (*3/10*) if no objections. After that will cut a
RC build for 3.5.3.

Please let me know what you think about this plan and any concerns /
comments are welcome.

-- 
Cheers
Michael.

using java 8 code

[Benjamin Reed]

have people given thought about moving to java8? i'm really not that
excited about moving to java8, but we are running into libraries that
we want to use that are compiled with java8.

zookeeper.4lw.commands.whitelist to branch-3.4.
Unlike branch-3.5 where all 4lw (with few exceptions) is disabled by 
default, for branch-3.4 only "wchp" and "wchc" are disabled by default - since 
4lw is widely used and there is no alternatives in branch-3.4 so we just 
disable the exploitable ones.

> 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.
