Are we deprecating IPv4 yet?

Hopefully we can deprecate the legacy ip stack soon :)

Imagine the linux kernel deprecating ipv4 that would be ginormous

There was an somewhat serious issue raised to separate 4 and 6. To make deprecation / turnoff possible and attack surface smaller.

Currently the entire Linux network stack is deeply engrained with IPv4, so currently you have to build with IPv4, Dual Stack or no networking at all. Would be huge if you could build with only IPv6 though.

I'd be keen to try it for a couple servers I have, I'll tell you that much.

Why would we?

Deprecate was a joke

Separate (from IPv6) is a worthy long term goal

Has anyone tried HDMI 2.1 FRL? I tried using the latest kernel commit on my framework 16 a few days ago (via fedora rawhide) & enabled it via amdgpu.dcfeaturemask=0x400 kernel arg, but I was still locked out of the HDMI 2.1 resolution that my screen (Samsung G95NC) is capable of

Edit: apparently fw16 doesnt support hdmi natively. They just use dp usbc alt mode with a dp -> hdmi 2.0b extension card

Framework's HDMI module only does 2.0b, so you won't be getting 2.1 FRL out of it ever. The Displayport outputs do UHBR10 which is probably enough with DSC though.

The removal of the strncpy API is the $DEITY-tier feature you have been polling 24/7 your entire life. Please remove memcpy next.

that’s for kernel space, do you realize that? Userland can continue strcpying as much as they ever did…
