36b74766f2 ("mm: security: introduce init_on_alloc=1 and .."): general protection fault: 0000 [#1] PREEMPT SMP PTI
by kernel test robot
Greetings,
0day kernel testing robot got the below dmesg and the first bad commit is
https://git.kernel.org/pub/scm/linux/kernel/git/kees/linux.git kspp/meminit/heap-v2
commit 36b74766f295e0898345865a0511a443cf90aa13
Author: Alexander Potapenko <glider(a)google.com>
AuthorDate: Tue May 14 16:35:34 2019 +0200
Commit: Kees Cook <keescook(a)chromium.org>
CommitDate: Wed May 15 15:23:43 2019 -0700
mm: security: introduce init_on_alloc=1 and init_on_free=1 boot options
The new options are needed to prevent possible information leaks and
make control-flow bugs that depend on uninitialized values more
deterministic.
init_on_alloc=1 makes the kernel initialize newly allocated pages and heap
objects with zeroes. Initialization is done at allocation time at the
places where checks for __GFP_ZERO are performed.
init_on_free=1 makes the kernel initialize freed pages and heap objects
with zeroes upon their deletion. This helps to ensure sensitive data
doesn't leak via use-after-free accesses.
Both init_on_alloc=1 and init_on_free=1 guarantee that the allocator
returns zeroed memory. The only exception is slab caches with
constructors. Those are never zero-initialized to preserve their semantics.
For SLOB allocator init_on_free=1 also implies init_on_alloc=1 behavior,
i.e. objects are zeroed at both allocation and deallocation time.
This is done because SLOB may otherwise return multiple freelist pointers
in the allocated object. For SLAB and SLUB enabling either init_on_alloc
or init_on_free leads to one-time initialization of the object.
Both init_on_alloc and init_on_free default to zero, but those defaults
can be overridden with CONFIG_INIT_ON_ALLOC_DEFAULT_ON and
CONFIG_INIT_ON_FREE_DEFAULT_ON.
Slowdown for the new features compared to init_on_free=0,
init_on_alloc=0:
hackbench, init_on_free=1: +7.62% sys time (st.err 0.74%)
hackbench, init_on_alloc=1: +7.75% sys time (st.err 2.14%)
Linux build with -j12, init_on_free=1: +8.38% wall time (st.err 0.39%)
Linux build with -j12, init_on_free=1: +24.42% sys time (st.err 0.52%)
Linux build with -j12, init_on_alloc=1: -0.13% wall time (st.err 0.42%)
Linux build with -j12, init_on_alloc=1: +0.57% sys time (st.err 0.40%)
The slowdown for init_on_free=0, init_on_alloc=0 compared to the
baseline is within the standard error.

[ubsan] f0996bc297: netperf.Throughput_total_tps -7.6% regression
by kernel test robot
Greeting,
FYI, we noticed a -7.6% regression of netperf.Throughput_total_tps due to commit:
commit: f0996bc2978e02d2ea898101462b960f6119b18f ("ubsan: Fix nasty -Wbuiltin-declaration-mismatch GCC-9 warnings")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
in testcase: netperf
on test machine: 8 threads Intel(R) Core(TM) i7-4770 CPU @ 3.40GHz with 8G memory
with following parameters:
ip: ipv4
runtime: 300s
nr_threads: 200%
cluster: cs-localhost
test: TCP_RR
cpufreq_governor: performance
ucode: 0x27
test-description: Netperf is a benchmark that can be use to measure various aspect of networking performance.
test-url: http://www.netperf.org/netperf/
Details are as below:
-------------------------------------------------------------------------------------------------->
To reproduce:
git clone https://github.com/intel/lkp-tests.git
cd lkp-tests
bin/lkp install job.yaml # job file is attached in this email
bin/lkp run job.yaml

[x86/speculation/mds] 22dd836508: will-it-scale.per_process_ops -3.8% regression
by kernel test robot
Greeting,
FYI, we noticed a -3.8% regression of will-it-scale.per_process_ops due to commit:
commit: 22dd8365088b6403630b82423cf906491859b65e ("x86/speculation/mds: Add mitigation mode VMWERV")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
in testcase: will-it-scale
on test machine: 192 threads Skylake-SP with 256G memory
with following parameters:
nr_task: 100%
mode: process
test: getppid1
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:

[x86/speculation/mds] bc1241700a: unixbench.score -49.0% regression
by kernel test robot
Greeting,
FYI, we noticed a -49.0% regression of unixbench.score due to commit:
commit: bc1241700acd82ec69fde98c5763ce51086269f8 ("x86/speculation/mds: Add mitigation control for MDS")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
in testcase: unixbench
on test machine: 16 threads Intel(R) Xeon(R) CPU D-1541 @ 2.10GHz with 8G memory
with following parameters:
runtime: 300s
nr_task: 1
test: syscall
cpufreq_governor: performance
ucode: 0x7000017
test-description: UnixBench is the original BYTE UNIX benchmark suite aims to test performance of Unix-like system.
test-url: https://github.com/kdlucas/byte-unixbench
In addition to that, the commit also has significant impact on the following tests:
