Oracle Linux 7.4

26 Settembre 2017

Oracle Linux

Oracle Linux

Oracle Linux è una distribuzione Linux di classe enterprise supportata da Oracle ed è basata su Red Hat Enterprise Linux (100% compatibile).

Versione 7.4

Questa versione contiene (in Inglese):

Enhancements to Oracle Linux 7 included in this update are included for several key areas, including Security, support for Cloud and Container environments, and Performance.

Security

Oracle Linux 7 Update 4 continues to enhance your security stance with several new capabilities, including:

  • UEFI Secure Boot

A system in Secure Boot mode loads only those boot loaders and kernels that have been signed by Oracle. Oracle has updated the kernel and grub2 packages to sign them with a valid Extended Validation (EV) certificate. The EV certificate has been compiled into the shim binary and has been signed by Microsoft.

  • openSSH now uses SHA-2

By default, the algorithm for public key signatures that is used in this release is SHA-2. SHA-1 is available for backward compatibility purposes only.

  • payload_gpgcheck option to yum

Enhances security during installation. The new payload_gpgcheck option enables yum to perform a GNU Privacy Guard (GPG) signature check on the payload sections of packages. This capability provides enhanced security and integrity when installing packages.

  • New NBDE security packages

NBDE enables you to encrypt root volumes of hard drives on physical machines without requiring you to manually enter a password when the systems are rebooted.

  • New usbguard package

The USBGuard software framework provides system protection against intrusive USB devices by implementing basic whitelisting and blacklisting capabilities that are based on device attributes.

Cloud and Containers Enhancements

Oracle Linux 7 Update 4 continues enhancing our customers’ cloud and container deployments.

  • Btrfs

Btrfs is the ideal filesystem for supporting containers in the cloud. We continue to support and enhance Btrfs in Oracle Linux 7 with Unbreakable Enterprise Kernel Release 4 allowing you to continue to use Btrfs for your container cloud deployments.

  • User Namespace

Prevents container users from being able to gain the same privileges at the global level by allowing separation of the container namespace from the underlying operating system namespace.

  • Spacewalk

Oracle Linux 7 Update 4 makes it even easier to install and add a system to Spacewalk by not requiring the spacewalk client to be installed before registering with the Spacewalk server.

Performance Enhancements

Oracle Linux 7 Update 4 continues to improve our already proven leadership in enterprise performance. Notable changes include:

  • Improved operating system scalability and performance

Replaced ticket spin locks with queued spin locks which provide better scalability under contention and higher performance overall.

  • Addition of http-parser performance package

http-parser is designed for high performance web applications by eliminating buffering, system calls and allowing interrupts.

  • Addition of libfastjson package

libfastjson is a limited feature set JSON library that provides significantly improved performance, compared to json-c.
