#59932 — Bug#886822: linux: KPTI backport lacks pti-related flags in /proc/cpuinfo

Source: linux
Version: 4.9.65-3+deb9u2
Severity: wishlist
Control: found -1 3.16.51-3+deb8u1

Dear Maintainer,

The backport of KPTI/KAISER to 4.9 and 3.16 lacks the pti CPU flag and 
the cpu_insecure bug found in /proc/cpuinfo in 4.14. While this does not 
affect core KPTI functionality, it makes it harder to determine whether 
a system is running with pti enabled without examining kernel logs.

Please consider backporting the relevant changes.

Regards,
Apollon

Correcting myself:

The flag is there, but it's called "kaiser" and not "pti". This seems to 
be the same throughout upstream backports of the patchset.

Feel free to close this bug report if you wish!
