This option is now needed for Kernel Self Protection system to be
available.
|
|
|
|
| |
This option no longer exists in versions >= 5.18.7.
|

This should be safe to have enabled (but unused) and gives us an extra
layer of potential mitigation of SMT side channels.

The Gentoo KSP recommendations have changed slightly again, now
requiring three different settings instead of just one. Additionally, in
order to enable KSP at all, CONFIG_MODIFY_LDT_SYSCALL needs to be unset.
|
|
|
|
|
|
| |
An upcoming commit updates to the latest KSP recommendations and
requires this particular setting as a direct dependency for
CONFIG_SECURITY_YAMA.

The newer versions of sys-kernel/gentoo-sources do not have this switch
anymore, instead relying only on the architecture-specific switches.
Remove it.

This setting pulls in a set of recommended settings [1] from the Kernel
Self Protection Project. We are pretty sure that we exhaustively set all
these manually already, but since Gentoo upstream provides this option,
make use of it too.

These options have either been merged into others or enabled
unconditionally.
