All users of the Linux 4.9 and 4.4 kernel series must update

Immediately after announcing the release of the first maintenance update to the Linux 4.10 kernel series, renowned kernel maintainer Greg Kroah-Hartman announced the availability of the Linux 4.9.13 and 4.4.52 LTS kernels.

This is a bit unexpected because it's been only three days since the Linux 4.9.12 and 4.4.51 LTS kernels have been released, so you can imagine that the changes implemented in today's Linux kernel 4.9.13, which was finally marked as longterm on kernel.org, and Linux kernel 4.4.52 LTS are kept to a minimum. According to their appended shortlogs, a total of 31 files were changed in Linux 4.9.13 LTS, with 365 insertions and 122 deletions, and 24 files in Linux 4.4.52 LTS, with 218 insertions and 121 deletions.

"I'm announcing the release of the 4.9.13 [and 4.4.52] kernel. All users of the 4.9 [and 4.4.y] kernel series must upgrade. The updated 4.9.y git tree can be found at: git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git linux-4.9.y and the updated 4.4.y git tree can be found at: git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git linux-4.4.y, and can be browsed at the normal kernel.org git web browser: http://git.kernel.org/?p=linux/kernel/git/stable/linux-stable.git;a=summary," said Greg Kroah-Hartman.

Various networking improvements, updated drivers

Both Linux 4.9.13 and 4.4.52 LTS kernels include a bunch of updated USB (ark3116, cp210x, mos7840, spcp8x5, opticon, and ftdi_sio), networking (Realtek rtlwifi, Mellanox mlx5 Ethernet), RTC and TTY drivers. A couple of small fixes have been implemented for the x86 architecture and XFS file system, and the networking stack was updated with various Datagram Congestion Control Protocol (DCCP), IrDA (Infrared Data Association), kernel connection multiplexer (KCM), Logical Link Control (LLC), and Netfilter improvements.

If you're using a GNU/Linux distribution powered by a kernel from the long-term supported Linux 4.9 or 4.4 series, you are urged to update as soon as possible to the Linux kernel 4.9.13 LTS or Linux kernel 4.4.52 LTS, which you can download from the stable repositories of your operating system when they become available there. OS vendors using these kernels are also urged to download the source tarballs right now from kernel.org or via our website and update their systems.
