Red Hat Company released Red Hat Enterprise Linux 7.7 distribution. RHEL 7.7 Install Images available for download by registered Red Hat Customer Portal users only and prepared for the x86_64, IBM POWER7+, POWER8 (big endian and little endian), and IBM System z architectures.

  • Added support for additional cipher suites in the default certificate system, including TLS_DHE_RSA_WITH_AES_256_GCM_SHA384, TLS_ECDHE_ECDSA_WITH_AES_256_CBC/GCM_SHA384,
    TLS_ECDHE_RSA_WITH_AES_128_CBC/GCM_SHA256, TLS_ECDHE_RSA_WITH_AES_256_CBC/GCM_SHA384 and TLS_RSA_WITH_AES_256_GCM_SHA384;

  • The maximum number of nodes in a RHEL-based failover cluster has been increased from 16 to 32;
  • For all architectures, IMA (Integrity Measurement Architecture) support is provided to check the integrity of files and their associated metadata based on pre-stored hashes and EVM (extended verification module) to protect extended file attributes (xattrs) from attacks aimed at violating their integrity (EVM will not allow an offline attack, in which an attacker can change metadata, for example, by booting from his drive);
  • Added a lightweight toolkit for managing isolated containers, using to build containers Buildah, for start - podman and to search for ready-made images - Skopje;
  • New installs of Specter V2 attack protection now use Retpoline ("spectre_v2=retpoline") instead of IBRS by default;
  • The source code for the real-time edition of kernel-rt is synchronized with the main kernel;
  • bind DNS server updated to branch 9.11, and ipset until release 7.1. Added rpz-drop rule to block attacks using DNS as a traffic booster;
  • Added the ability to set routing rules by source address (policy routing) and support for VLAN filtering on network bridge interfaces in NetworkManager;

Improved performance and reliability of converting VMWare virtual machines. Added support for converting virtual machines using UEFI firmware to run in Red Hat Virtualization (RHV);
  • The gcc-libraries package has been updated to version 8.3.1. Added package compat-sap-c++-8 with a variant of libstdc++ runtime library compatible with SAP applications;
