Title:
disable CONFIG_KFENCE_STATIC_KEYS in linux 5.15
Status in linux package in Ubuntu:
Expired
Status in linux source package in Jammy:
Expired
Bug description:
[Impact]
KFENCE devs are changing CONFIG_KFENCE_STATIC_KEYS to be disabled by
default, because it's introducing more problems than benefits:
https://lore.kernel.org/all/20211019102524.2807208-2-el...@google.com/T/#u
This also seems to trigger QEMU bugs during the systemd autopkgtest, like:
https://bugs.launchpad.net/qemu/+bug/1920934
[Test case]
Run systemd autopkgtest.
[Fix]
Disable CONFIG_KFENCE_STATIC_KEYS.
[Regression potential]
We may experience an overall performance regression for not using
static branches in the KFENCE code.
