Beta: CL6 and Hybrid kernel 2.6.32-458.18.1.lve1.2.41

This is not our typical beta update. This is major update with lots of changes and bug fixes. We have merged some of the work we were doing for the past 6 months, so be careful running it on production servers.

lve-utils 1.3-12 released

We are releasing new version of lve-utils 1.3-12 to production.
This update relates to CLN downtime last week. Previous version of lve-utils would run a license check every 12 hours on the hour. Due to differences in timezones it was spread around -- but we had big enough concentration of servers in two time zones that would sometimes cause overload of the CLN. That created cascading problem, as servers licensed by IP would try to re-license, which would significantly add to a load problem. The problem snowballed this Tuesday, causing CLN downtime.


While we are adding safety checks and optimizations into CLN, we want to fix the cron job issue in lve-utils.
Now, when cron job is installed, the time to run is randomly selected.
Additionally, we have switched to one check per day instead of two.

Changelog:
  • Randomly select the time to run cloudlinux-cron cronjob
  • Spec file clean up

To update to new version of lve-utils, please, run:
$ yum update lve-utils

beta: mod_suphp 0.7.2

We have prepared mod_suphp 0.7.2 RPM that updates suPHP to latest version.
This is not for cPanel customers (as EasyApache builds suPHP from sources).

This release fixes a security issue that was introduced with the 0.7.0 release. This issue affected the source-highlighting feature and could only be exploited, if the suPHP_PHPPath option was set. In this case local users which could create or edit .htaccess files could possibly execute arbitrary code with the privileges of the user the webserver was running as.

This RPM packages two binaries. One compiled with 'paranoid' option, and another one compiled with 'owner' option.
Paranoid version of binary installed by default (as always). That is the version that requires suPHP_ settings in apache vhost configs.

To update, run:
$ yum update mod_suphp --enablerepo=cloudlinux-updates-testing

Beta: mod_fcgid 2.3.9

This is a beta release of mod_fcgid. As we have large number of customers using this module, we wanted to update it to latest version, instead of tracking what is in RHEL repositories. If you are running mod_fcgid from our repo on multiple servers -- please, try it to make sure it doesn't break any of your settings.
While it should be backwards compatible with previous versions, there is a possibility of regression

Changelog:
  • SECURITY: Fix possible heap buffer overwrite CVE-2013-4365 (cve.mitre.org)
  • Add experimental cmake-based build system for Windows.
  • Correctly parse quotation and escaped spaces in FcgidWrapper and the AAA Authenticator/Authorizor/Access directives' command line argument as currently documented.
  • Honor quoted FcgidCmdOptions arguments (notably for InitialEnv assignments).
  • Conform script response parsing with mod_cgid and ensure no response body is sent when ap_meets_conditions() determines that request conditions are met.
  • Improve logging in access control hook functions.
  • Avoid making internal sub-requests and processing Location headers when in FCGI_AUTHORIZER mode, as the auth hook functions already treat Location headers returned by scripts as an error sinc redirections are not meaningful in this mode.
To update:
$ yum update mod_fcgid --enablerepo=cloudlinux-updates-testing

Beta: cagefs 5.1-7

New beta version of CageFS is available. It introduces few minor fixes.

Changelog:
  • proxyexecd service: call 'killall -s 9 proxyexec' when 'killproc proxyexec' failed
  • cPanel: add logic for detect EasyApache dir
  • Plesk: exclude horde_sysuser from CageFS

To update:
$ yum update cagefs --enablerepo=cloudlinux-updates-testing

beta: lve-utils 1.3-12

One of the causes for CLN downtime this week was release of lve-utils 1.3 on October 1st. That release introduced a license check that would run via cron job every 12 hours. The way it was implemented - it would run every 12 hours on the hour. So we had significant spike on the hour, every hour. Due to differences in timezones it was spread around -- but we had big enough concentration of servers in two time zones that would sometimes cause overload of the CLN. That in case created cascading problem, as servers licensed by IP would try to re-license, which would significantly add to a load problem. The problem snowballed this Tuesday, causing CLN downtime.
While we are adding safety checks and optimizations into CLN, we want to also fix this cron job issue in lve-utils.
Now, when cron job is installed, the time to run is randomly selected. We also switched to one check per day instead of to.

Changelog:
  • Randomly select the time to run cloudlinux-cron cronjob
  • Spec file clean up
To update to new version of lve-utils, please, run:
$ yum update lve-utils --enablerepo=cloudlinux-updates-testing

MySQL 5.5 for MySQL Governor Issue Follow Up

As many of you might be aware, we have released MySQL 5.5 update that broke mysqli compatibility for many customers. Here I want to explain what happens, and the steps we are planning to take to prevent such things from happening in the future.

Sequence of events:
  • A new patch was applied to MySQL 5.5 that fixed backward compatibility with libmysqlclient16 library experienced by one customer
  • The patch was tested on customer's server
  • MySQL was pushed into MySQL Governor repositories
  • It was automatically downloaded and installed by yum update or upcp running on customer's server
  • The update caused compatibility issues with mysqli php extension, resulting in multiple websites being down
  • Within 30 minutes of us understanding what happened, we have removed new MySQL from repository and provided advisory on how to fix the issue. Yet, significant number of customers had updated by that time.
Here are is what we consider to have caused the problem for so many systems:


  • MySQL package should have gone through beta process first. We consider MySQL governor to be a beta overall, and we beta test most software we release. Beta testing requires administrators to manually install the update version of software. It limits the number of systems where updates are executed, and makes sure that administrator knows what caused the issue. It allows admins with multiple systems to test new software on one or two servers, before it is unleashed on all their servers.
  • Incomplete testing was done on MySQL package. Developer decided that given how small patch is, full testing is not required
  • No announcement went out about the change.
Here is what we plan to do to address the identified issues:


  • We will split MySQL governor repositories into beta and stable repositories
  • Beta repository will be disabled by default. Stable repository will be enabled
  • All new versions of MySQL packages will go into beta repositories, and to update to beta version, user would have to run: mysqlgovernor.py --update-mysql-beta
  • Such beta releases will be announced via our blog and mailing list
  • Once we are confident in a new version -- we will move it to stable
  • This process will continue once MySQL Governor will be moved to stable channel itself
  • We will create automated tests for building php using EasyApache that will run on each build
  • We will create php page that will try to use new MySQL build using mysqli and make it part of automated testing
  • All versions of alt-php will be tested using this page as well against new MySQL build.
The ETA for repository changes is 2 weeks
The ETA for full cycle automated testing is 6 week.

I would like to welcome any feedback and recommendations regarding the issue and the approach we are taking to prevent such issues from happening again.

CL6 and Hybrid kernel 2.6.32-458.18.1.lve1.2.39 moved to production

Beta: MySQL 5.5 and 5.6 update for MySQL governor

Recent update of MySQL 5.5 and 5.6 has broken mysqli php library for quite a number of our customers.
We quickly removed the update, and provides steps to roll back. Yet, it did cause downtime for a number of our customers.
In the past two days we repackages MySQL and made sure it works correctly -- so now it is again safe to install MySQL Governor and update MySQL software.

Installation instructions are available here: http://docs.cloudlinux.com/index.html?installation3.html

At this moment we are doing review of our processes related to MySQL governor software. By the end of this week we are planning to provide you with a complete explanation of what happened, and what kind of processes we are adding in place to prevent such issues in the future.

Beta: MySQL Governor 1.0-29

New version of MySQL governor had been added. This is a major update that brings some new features that should improve MySQL Governor significantly. Among changes:
