[x86/xen] f030aade91: will-it-scale.per_process_ops 5.6% improvement
by kernel test robot
Greeting,
FYI, we noticed a 5.6% improvement of will-it-scale.per_process_ops due to commit:
commit: f030aade9165080f3539fb86fc2ce9ffc391813c ("x86/xen: Move pv specific parts of arch/x86/xen/mmu.c to mmu_pv.c")
https://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git master
in testcase: will-it-scale
on test machine: 8 threads Ivy Bridge with 16G memory
with following parameters:
nr_task: 100%
mode: process
test: poll2
ucode: 0x20
cpufreq_governor: performance
test-description: Will It Scale takes a testcase and runs it from 1 through to n parallel copies to see if the testcase will scale. It builds both a process and threads based test in order to see any differences between the two.
test-url: https://github.com/antonblanchard/will-it-scale
Details are as below:

To reproduce:
git clone https://github.com/intel/lkp-tests.git

commit abaa5e490dc10e5c4acfa5dd30fa2cbf4b699934
Author: Brijesh Singh <brijesh.singh(a)amd.com>
AuthorDate: Thu Sep 13 16:51:11 2018 -0500

CommitDate: Fri Sep 14 08:01:11 2018 +0800
x86/kvm: use __bss_decrypted attribute in shared variables
The recent removal of the memblock dependency from kvmclock caused a SEV
guest regression because the wall_clock and hv_clock_boot variables are
no longer mapped decrypted when SEV is active.
Use the __bss_decrypted attribute to put the static wall_clock and
hv_clock_boot in the .bss..decrypted section so that they are mapped
decrypted during boot.
In the preparatory stage of CPU hotplug, the per-cpu pvclock data pointer
assigns either an element of the static array or dynamically allocated
memory for the pvclock data pointer. The static array are now mapped
decrypted but the dynamically allocated memory is not mapped decrypted.
However, when SEV is active this memory range must be mapped decrypted.
Add a function which is called after the page allocator is up, and
allocate memory for the pvclock data pointers for the all possible cpus.
Map this memory range as decrypted when SEV is active.

c72bd0d51b ("kernel: prevent submission of creds with higher .."): BUG: unable to handle kernel NULL pointer dereference at 0000005c

Greetings,

kernel: prevent submission of creds with higher privileges inside container
Adversaries often attack the Linux kernel via using
commit_creds(prepare_kernel_cred(0)) to submit ROOT
credential for the purpose of privilege escalation.
For processes inside the Linux container, the above
approach also works, because the container and the
host share the same Linux kernel. Therefore, we en-
force a check in commit_creds() before updating the
cred of the caller process. If the process is insi-
de a container (judging from the Namespace ID) and
try to submit credentials with higher privileges t-
han current (judging from the uid, gid, and cap_bset
in the new cred), we will stop the modification. We
consider that if the namespace ID of the process is
different from the init Namespace ID (enumed in /i-
nclude/linux/proc_ns.h), the process is inside a c-
ontainer. And if the uid/gid in the new cred is sm-
aller or the cap_bset (capability bounding set) in
the new cred is larger, it may be a privilege esca-
lation operation.
