Description Sam James archtester Gentoo Infrastructure gentoo-dev Security 2020-06-09 01:26:06 UTC 
Patches have been submitted by ARM to address the new Straight Line Speculation (SLS) vulnerability.

Using this bug to keep track of the status upstream, and then to determine what we do in Gentoo (like before, bug 646758, but maybe with more success here).

Patch series: https://gcc.gnu.org/pipermail/gcc-patches/2020-June/547520.html
Comment 1 Sam James archtester Gentoo Infrastructure gentoo-dev Security 2020-06-09 01:27:26 UTC 
To be clear, I do not expect toolchain@ to add these patches themselves before they are accepted upstream -- this is just to keep track.
Comment 2 Sam James archtester Gentoo Infrastructure gentoo-dev Security 2020-07-24 16:25:25 UTC 
The fixes are being backported to 9.x and 10.x: https://gcc.gnu.org/pipermail/gcc-patches/2020-July/550369.html.
Comment 3 John Helmert III archtester Gentoo Infrastructure gentoo-dev Security 2021-11-11 16:41:04 UTC 
Looks like the patches made it into 9.4.0 (20da13e395bde597d8337167c712039c8f923c3b), 10.3.0 (50703e93a82df4af69c692d01b980b3b2c0eb53e), and 11.1.0 (a9ba2a9b77bec7eacaf066801f22d1c366a2bc86). Doesn't look like it was backported to 8.x, so I guess we're at [cleanup]?
Comment 4 John Helmert III archtester Gentoo Infrastructure gentoo-dev Security 2022-07-15 04:14:04 UTC 
8.x and 9.x are now masked.
Comment 5 Andreas K. Hüttel archtester gentoo-dev 2023-08-24 19:39:36 UTC 
All affected versions are gone.
