There is a lot of concern in the linux gnu community for the bug
https://www.theregister.co.uk/2018/01/0 ... explained/
Debian and also Slackware, have provided some patches to solve the problem, is there a patch for Salixos, or do you need to install the patched kernel from Slackware?
Thanks

You need to install the patched kernel available in the Salix repositories, which is the same as the patched kernel from Slackware.simone wrote:There is a lot of concern in the linux gnu community for the bug

Thanks Gapan!
Can the kernel-headers also be updated?

Don't forget to update the bootloader before rebooting. Anyone in doubt, check the instructions in the wiki.

I wonder if the CONFIG_PAGE_TABLE_ISOLATION (KPTI) is available only for x86_64.

Re: spectre-and-meltdown-security-kernel-upgrades
I don't have access to a 32bit system at this moment, but it should make no difference. You should be patched if you have upgraded to the latest kernel availabe in the repos.
Re: spectre-and-meltdown-security-kernel-upgrades
Hi, gapan,
It is not available in /boot/config-huge-smp-4.4.111-smp ... I will wait a few months for my processor type to catch up.
Saludos.

Hi, gapan and mimosa,
Thank you both for the guidance offered in this thread. I hadn't yet installed the patched kernel, but I did it this afternoon.
Here's a link to the Wiki instructions mentioned by mimosa:
https://docs.salixos.org/wiki/How_to_in ... ent_kernel
"How to install a different kernel."
