NetworkManager 1.18, an interface to simplify network configuration, is out. Plug-ins with support for VPN, OpenConnect, PPTP, OpenVPN and OpenSWAN are developed as part of own development cycles.

Main innovations of NetworkManager 1.18:

  • Added support for routing rules at the source address (policy routing), the need for which has matured after adding support for VPN WireGuard in the past release (needed to simplify the configuration of separate forward traffic forwarding to the VPN connection point address);
  • Added the ability to filter VLANs in network bridges;
  • Added support for TLV-structures LLDP (Link Layer Discovery Protocol) defined in the IEEE 802.1 and IEEE 802.3 standards for the exchange of information about the parameters of equipment in the local network;
  • The infiniband / IPoIB profiles provide the possibility of using large MTU values;
  • In the nmcli utility, the processing of lists of options with connection parameters has been improved.

Oracle to Release Unbreakable Kernel R5U3

The update for the kernel, that can be used as alternative for Red Hat Enterprise Linux used in the Oracle Linux is based on the Linux 4.14

Oracle has released the third functional update for the Unbreakable Enterprise Kernel R5 kernel, positioned for use in the Oracle Linux distribution as an alternative to the regular kernel package from Red Hat Enterprise Linux. The kernel is available for x86_64 and ARM64 architectures (aarch64). Kernel sources, including breakdowns into individual patches, are published in the public Oracle Git repository.

The Unbreakable Enterprise Kernel 5 package is based on the Linux 4.14 kernel (UEK R4 was based on the 4.1 kernel), which is supplemented with new features, optimizations and fixes, as well as tested for compatibility with most applications running in RHEL and specially optimized for working with industrial software and Oracle hardware. Installation and src packages with the UEK R5U1 kernel are prepared for Oracle Linux 7 (there are no obstacles to using this kernel in similar versions of RHEL, CentOS and Scientific Linux).

Key improvements:

  • Improved support for 64-bit systems based on the ARM architecture. Updated drivers for ARM.
  • InfiniBand includes on-demand paging support, which allows you to reflect memory through a processor for accessing unallocated pages of memory (page faults), i.e. consume memory when it is actually being used.
  • In XFS, a deadlock was eliminated, which caused the locks to freeze and not free.
  • CIFS resolved an issue that could lead to POSIX lock leaks and crashes.
  • Bug fixes resolving issues with incompatibility of certain equipment with QEMU / KVM.
  • Device drivers are synchronized with the Linux kernel 4.14.35. The driver for Broadcom Emulex LightPulse Fiber Channel SCSI has been updated to version
