Hi Po-Hsu,
For artful/arm64, when I implemented the test, I hadn't realized
CONFIG_VMAP_STACK had been backported to the 4.13/artful kernel (in
7b7dbeeef3b73294e525f368b03c3890459992a6). I have fixed the qrt test to
reflect that in https://git.launchpad.net/qa-regression-
testing/commit/?id=6cda576b8fc2f3c6f08d7f6a0bd7408918180ab8 .
For bionic 4.15/linux-kvm, the kernel config there is missing having
CONFIG_VMAP_STACK set:
$ grep VMAP_STACK debian.kvm/config/config.common.ubuntu
CONFIG_HAVE_ARCH_VMAP_STACK=y
# CONFIG_VMAP_STACK is not set
The security team would like to see that fixed.
Thanks!
