[slackware-security]  Slackware 14.2 kernel (SSA:2018-057-01)

New kernel packages are available for Slackware 14.2 to mitigate the
speculative side channel attack known as Spectre variant 1.

Here are the details from the Slackware 14.2 ChangeLog:
patches/packages/linux-4.4.118/*:  Upgraded.
  This kernel includes __user pointer sanitization mitigation for the Spectre
  (variant 1) speculative side channel attack.
  Be sure to upgrade your initrd after upgrading the kernel packages.
  If you use lilo to boot your machine, be sure lilo.conf points to the correct
  kernel and initrd and run lilo as root to update the bootloader.
  If you use elilo to boot your machine, you should run eliloconfig to copy the
  kernel and initrd to the EFI System Partition.
  For more information, see:
  (* Security fix *)

Installation instructions:

Upgrade the packages as root:
# upgradepkg kernel-*.txz

If you are using an initrd, you'll need to rebuild it.

For a 32-bit SMP machine, use this command (substitute the appropriate
kernel version if you are not running Slackware 14.2):
# /usr/share/mkinitrd/ -k 4.4.118-smp | bash

For a 64-bit machine, or a 32-bit uniprocessor machine, use this command
(substitute the appropriate kernel version if you are not running
Slackware 14.2):
# /usr/share/mkinitrd/ -k 4.4.118 | bash

Please note that "uniprocessor" has to do with the kernel you are running,
not with the CPU.  Most systems should run the SMP kernel (if they can)
regardless of the number of cores the CPU has.  If you aren't sure which
kernel you are running, run "uname -a".  If you see SMP there, you are
running the SMP kernel and should use the 4.4.118-smp version when running
mkinitrd_command_generator.  Note that this is only for 32-bit -- 64-bit
systems should always use 4.4.118 as the version.

If you are using lilo or elilo to boot the machine, you'll need to ensure
that the machine is properly prepared before rebooting.

If using LILO:
By default, lilo.conf contains an image= line that references a symlink
that always points to the correct kernel.  No editing should be required
unless your machine uses a custom lilo.conf.  If that is the case, be sure
that the image= line references the correct kernel file.  Either way,
you'll need to run "lilo" as root to reinstall the boot loader.

If using elilo:
Ensure that the /boot/vmlinuz symlink is pointing to the kernel you wish
to use, and then run eliloconfig to update the EFI System Partition.
