x86/irq/64: Split the IRQ stack into its own pages
Currently the IRQ stack is hardcoded as the first page of the percpu area,
and the stack canary lives on the IRQ stack. The former gets in the way of
adding an IRQ stack guard page, and the latter is a potential weakness in
the stack canary mechanism.
Split the IRQ stack into its own private percpu pages.

mm: Check user stack pointer is mapped with MAP_STACK
By marking stack VMAs with VM_USERSTACK, we can perform optional checks
on entry to the kernel from system calls and user faults to ensure that
the user stack pointer does indeed point to a stack VMA. If the stack
pointer is found to point elsewhere, a SIGSEGV can be delivered to the
current application.
This acts as a best-effort defense against stack-pivoting attacks.

https://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git WIP.x86/stackguards
commit 8b275b3754465d502d393f8ae8dd355b7067e73f
Author: Andy Lutomirski <luto(a)kernel.org>
AuthorDate: Fri Jul 13 19:01:23 2018 -0700

x86/irq/64: Remap the IRQ stack with guard pages
The IRQ stack lives in percpu space, so an IRQ handler that overflows it
will overwrite other data structures.
Use vmap() to remap the IRQ stack so that it will have the usual guard
pages that vmap/vmalloc allocations have. With this the kernel will panic
immediately on an IRQ stack overflow.
[ tglx: Move the map code to a proper place and invoke it only when a CPU
is about to be brought online. No point in installing the map at
early boot for all possible CPUs. Fail the CPU bringup if the vmap
fails as done for all other preparatory stages in cpu hotplug. ]

bfcf4bd96c ("x86/irq/64: Split the IRQ stack into its own pages"): double fault: 0000 [#1] PREEMPT SMP DEBUG_PAGEALLOC KASAN
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 WIP.x86/stackguards
commit bfcf4bd96c127fa67275b54554bea089424601f8
Author: Andy Lutomirski <luto(a)kernel.org>
AuthorDate: Fri Jul 13 17:27:40 2018 -0700
Commit: Thomas Gleixner <tglx(a)linutronix.de>
CommitDate: Fri Apr 5 09:23:30 2019 +0200
x86/irq/64: Split the IRQ stack into its own pages
Currently the IRQ stack is hardcoded as the first page of the percpu area,
and the stack canary lives on the IRQ stack. The former gets in the way of
adding an IRQ stack guard page, and the latter is a potential weakness in
the stack canary mechanism.
Split the IRQ stack into its own private percpu pages.

kbuild test bot messages interfering up patchwork
by Arkadiusz Hiler
Hey all,
I hope this is the correct place for requests regarding kbuild automated
messages.
The request: Add 'X-Patchwork-Hint: comment' to email headers the bot sends.
Why: https://gitlab.freedesktop.org/patchwork-fdo/patchwork-fdo/issues/21
TL;DR: sending patch in a reply to a patch overwrites the original one
breaks our workflow with mailing lists. Adding the above hint would fix
that.

Cheers,

[compiler] dfc95c6ebb: reaim.jobs_per_min -16.7% regression
by kernel test robot
Greeting,
FYI, we noticed a -16.7% regression of reaim.jobs_per_min due to commit:
commit: dfc95c6ebbf550ee91f70b67c45396685bf4e055 ("compiler-attribute: stop forcing __always_inline to inline marker")
https://git.kernel.org/cgit/linux/kernel/git/masahiroy/linux-kbuild.git build-test2
in testcase: reaim
on test machine: 256 threads Knights Landing with 96G memory
with following parameters:
runtime: 300s
nr_task: 100%
test: compute
cpufreq_governor: performance
test-description: REAIM is an updated and improved version of AIM 7 benchmark.
test-url: https://sourceforge.net/projects/re-aim-7/
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

3a5d5346ab ("locking/lockdep: Zap lock classes even with lock .."): WARNING: CPU: 0 PID: 7 at kernel/softirq.c:170 __local_bh_enable_ip
by kernel test robot
Greetings,
0day kernel testing robot got the below dmesg and the first bad commit is
https://github.com/bvanassche/linux for-next
commit 3a5d5346ab1f5d27593fe18af30ab6b7b76dff0d
Author: Bart Van Assche <bvanassche(a)acm.org>
AuthorDate: Tue Mar 26 10:51:45 2019 -0700

locking/lockdep: Zap lock classes even with lock debugging disabled
Commit a0b0fd53e1e6 ("locking/lockdep: Free lock classes that are no longer
in use") changed the behavior of lockdep_free_key_range() from
unconditionally zapping lock classes into only zapping lock classes if
debug_lock == true. Since the new behavior can cause cat /proc/lockdep to
crash due to a NULL pointer dereference, restore the pre-v5.1 behavior.
