[sched/fair] 070f5e860e: reaim.jobs_per_min -10.5% regression
by kernel test robot
Greeting,
FYI, we noticed a -10.5% regression of reaim.jobs_per_min due to commit:
commit: 070f5e860ee2bf588c99ef7b4c202451faa48236 ("sched/fair: Take into account runnable_avg to classify group")
https://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git master
in testcase: reaim
on test machine: 4 threads Intel(R) Core(TM) i3-3220 CPU @ 3.30GHz with 4G memory
with following parameters:
runtime: 300s
nr_task: 100%
test: five_sec
cpufreq_governor: performance
ucode: 0x21
test-description: REAIM is an updated and improved version of AIM 7 benchmark.
test-url: https://sourceforge.net/projects/re-aim-7/
If you fix the issue, kindly add following tag
Reported-by: kernel test robot <rong.a.chen(a)intel.com>
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
=========================================================================================

[sched/fair] 0b0695f2b3: phoronix-test-suite.compress-gzip.0.seconds 19.8% regression
by kernel test robot
Hi Vincent Guittot,
Below report FYI.
Last year, we actually reported an improvement "[sched/fair] 0b0695f2b3:
vm-scalability.median 3.1% improvement" on link [1].
but now we found the regression on pts.compress-gzip.
This seems align with what showed in "[v4,00/10] sched/fair: rework the CFS
load balance" (link [2]), where showed the reworked load balance could have
both positive and negative effect for different test suites.
And also from link [3], the patch set risks regressions.
We also confirmed this regression on another platform
(Intel(R) Core(TM) i7-8700 CPU @ 3.20GHz with 8G memory),
below is the data (lower is better).
v5.4 4.1
fcf0553db6f4c79387864f6e4ab4a891601f395e 4.01
0b0695f2b34a4afa3f6e9aa1ff0e5336d8dad912 4.89
v5.5 5.18
v5.6 4.62
v5.7-rc2 4.53
v5.7-rc3 4.59
It seems there are some recovery on latest kernels, but not fully back.
We were just wondering whether you could share some lights the further works
on the load balance after patch set [2] which could cause the performance
change?
And whether you have plan to refine the load balance algorithm further?
thanks

Below is the detail regression report FYI.
Greeting,
FYI, we noticed a 19.8% regression of phoronix-test-suite.compress-gzip.0.seconds due to commit:
commit: 0b0695f2b34a4afa3f6e9aa1ff0e5336d8dad912 ("sched/fair: Rework load_balance()")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
in testcase: phoronix-test-suite
on test machine: 16 threads Intel(R) Xeon(R) E-2278G CPU @ 3.40GHz with 32G memory

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/tip/tip.git x86/entry
commit b614345f52bcde8299a53132f5e48a9eb5a1f320
Author: Peter Zijlstra <peterz(a)infradead.org>
AuthorDate: Fri May 29 23:27:39 2020 +0200
Commit: Thomas Gleixner <tglx(a)linutronix.de>
CommitDate: Sat May 30 10:00:10 2020 +0200
x86/entry: Clarify irq_{enter,exit}_rcu()
Because:
irq_enter_rcu() includes lockdep_hardirq_enter()
irq_exit_rcu() does *NOT* include lockdep_hardirq_exit()
Which resulted in two 'stray' lockdep_hardirq_exit() calls in
idtentry.h, and me spending a long time trying to find the matching
enter calls.

percpu: make pcpu_alloc() aware of current gfp context
Since 5.7-rc1, on btrfs we have a percpu counter initialization for
which we always pass a GFP_KERNEL gfp_t argument (this happens since
commit 2992df73268f78 ("btrfs: Implement DREW lock")).
That is safe in some contextes but not on others where allowing fs
reclaim could lead to a deadlock because we are either holding some
btrfs lock needed for a transaction commit or holding a btrfs
transaction handle open. Because of that we surround the call to the
function that initializes the percpu counter with a NOFS context using
memalloc_nofs_save() (this is done at btrfs_init_fs_root()).
However it turns out that this is not enough to prevent a possible
deadlock because percpu_alloc() determines if it is in an atomic context
by looking exclusively at the gfp flags passed to it (GFP_KERNEL in this
case) and it is not aware that a NOFS context is set.
Because percpu_alloc() thinks it is in a non atomic context it locks the
pcpu_alloc_mutex. This can result in a btrfs deadlock when
pcpu_balance_workfn() is running, has acquired that mutex and is waiting
for reclaim, while the btrfs task that called percpu_counter_init() (and
therefore percpu_alloc()) is holding either the btrfs commit_root
semaphore or a transaction handle (done fs/btrfs/backref.c:
iterate_extent_inodes()), which prevents reclaim from finishing as an
attempt to commit the current btrfs transaction will deadlock.

This could be fixed by making btrfs pass GFP_NOFS instead of GFP_KERNEL
to percpu_counter_init() in contextes where it is not reclaim safe,
however that type of approach is discouraged since
memalloc_[nofs|noio]_save() were introduced. Therefore this change
makes pcpu_alloc() look up into an existing nofs/noio context before
deciding whether it is in an atomic context or not.

021e70c3a6 ("treewide: Replace one-element array with .."): BUG: KASAN: slab-out-of-bounds in alloc_pid

Greetings,

https://git.kernel.org/pub/scm/linux/kernel/git/gustavoars/linux.git testing/fam1
commit 021e70c3a66ced20bdfa6694d32bbb64bd8c954a

treewide: Replace one-element array with flexible-array
The current codebase makes use of one-element arrays in the following
form:
struct something {
int length;
u8 data[1];
};
struct something *instance;
instance = kmalloc(sizeof(*instance) + size, GFP_KERNEL);
instance->length = size;
memcpy(instance->data, source, size);
but the preferred mechanism to declare variable-length types such as
these ones is a flexible array member[1][2], introduced in C99:
struct foo {
int stuff;
struct boo array[];
};
By making use of the mechanism above, we will get a compiler warning
in case the flexible array does not occur last in the structure, which
will help us prevent some kind of undefined behavior bugs from being
inadvertently introduced[3] to the codebase from now on.
This issue was found with the help of Coccinelle.

by kernel test robot
Greeting,
FYI, we noticed the following commit (built with gcc-8):
commit: 68a05c6247d2aa67f5ada1009ffd19758e5914ea ("x86/traps: Mark fixup_bad_iret() noinstr")

in testcase: kernel-selftests
with following parameters:
group: kselftests-x86
test-description: The kernel contains a set of "self tests" under the tools/testing/selftests/ directory. These are intended to be small unit tests to exercise individual code paths in the kernel.
test-url: https://www.kernel.org/doc/Documentation/kselftest.txt
on test machine: qemu-system-x86_64 -enable-kvm -cpu SandyBridge -smp 2 -m 8G
