mailmap: add Martin Kepplinger's email

hugetlbfs: fix offset overflow in hugetlbfs mmap

thp: fix MADV_DONTNEED vs. numa balancing race
thp: reduce indentation level in change_huge_pmd()
z3fold: fix page locking in z3fold_alloc()
The copy_page is optimized memcpy for page-alinged address. If it is
used with non-page aligned address, it can corrupt memory which means
system corruption. With zram, it can happen with
1. 64K architecture
2. partial IO
3. slub debug
Partial IO need to allocate a page and zram allocates it via kmalloc.
With slub debug, kmalloc(PAGE_SIZE) doesn't return page-size aligned
address. And finally, copy_page(mem, cmem) corrupts memory.
So, this patch changes it to memcpy.
Actuaully, we don't need to change zram_bvec_write part because zsmalloc
returns page-aligned address in case of PAGE_SIZE class but it's not
good to rely on the internal of zsmalloc.
Note:
When this patch is merged to stable, clear_page should be fixed, too.
Unfortunately, recent zram removes it by "same page merge" feature so
it's hard to backport this patch to -stable tree.
I will handle it when I receive the mail from stable tree maintainer to
merge this patch to backport.

If mmap() maps a file, it can be passed an offset into the file at which
the mapping is to start. Offset could be a negative value when
represented as a loff_t. The offset plus length will be used to update
the file size (i_size) which is also a loff_t.
Validate the value of offset and offset + length to make sure they do
not overflow and appear as negative.
Found by syzcaller with commit ff8c0c53c4 ("mm/hugetlb.c: don't call
region_abort if region_chg fails") applied. Prior to this commit, the
overflow would still occur but we would luckily return ENOMEM.

Stress testing of the current z3fold implementation on a 8-core system
revealed it was possible that a z3fold page deleted from its unbuddied
list in z3fold_alloc() would be put on another unbuddied list by
z3fold_free() while z3fold_alloc() is still processing it. This has
been introduced with commit 5a27aa822 ("z3fold: add kref refcounting")
due to the removal of special handling of a z3fold page not on any list
in z3fold_free().
To fix this, the z3fold page lock should be taken in z3fold_alloc()
before the pool lock is released. To avoid deadlocking, we just try to
lock the page as soon as we get a hold of it, and if trylock fails, we
drop this page and take the next one.

NTLMSSP. The current code doesn't keep it in mind and fails a mount
for such servers if no security mechanism is specified. Fix this by
indicating that a server supports NTLMSSP if a security context isn't
returned during negotiate phase. This allows the code to use NTLMSSP
by default for SMB3 mounts.

There is a report that after commit 27622b061e ("cpufreq: Convert
to hotplug state machine"), the normal CPU offline/online cycle
fails on some platforms.
According to the ftrace result, this problem was triggered on
platforms using acpi-cpufreq as the default cpufreq driver,
and due to the lack of some ACPI freq method (eg. _PCT),
cpufreq_online() failed and returned a negative value, so the CPU
hotplug state machine rolled back the CPU online process. Actually,
from the user's perspective, the failure of cpufreq_online() should
not prevent that CPU from being brought up, although cpufreq might
not work on that CPU.
BTW, during system startup cpufreq_online() is not invoked via CPU
online but by the cpufreq device creation process, so the APs can be
brought up even though cpufreq_online() fails in that stage.
This patch ignores the return value of cpufreq_online/offline() and
lets the cpufreq framework deal with the failure. cpufreq_online()
itself will do a proper rollback in that case and if _PCT is missing,
the ACPI cpufreq driver will print a warning if the corresponding
debug options have been enabled.

Most CPUs do not have a hardware c1 counter,
and so turbostat derives c1 residency:
c1 = TSC - MPERF - other_core_cstate_counters
As it is not possible to atomically read these coutners,
measurement jitter can case this calcuation to "go negative"
when very close to 0. Turbostat detect that case and
simply prints c1 = 0.00%
But that check neglected to account for systems where the TSC
crystal clock domain and the MPERF BCLK domain are differ by
a small amount. That allowed very small negative c1 numbers
to escape this check and be printed as huge positve numbers.
This code begs for a bit of cleanup, but this patch
is the minimal change to fix the issue.

Under CONFIG_STRICT_DEVMEM, reading System RAM through /dev/mem is
disallowed. However, on x86, the first 1MB was always allowed for BIOS
and similar things, regardless of it actually being System RAM. It was
possible for heap to end up getting allocated in low 1MB RAM, and then
read by things like x86info or dd, which would trip hardened usercopy:
usercopy: kernel memory exposure attempt detected from ffff880000090000 (dma-kmalloc-256) (4096 bytes)
This changes the x86 exception for the low 1MB by reading back zeros for
System RAM areas instead of blindly allowing them. More work is needed to
extend this to mmap, but currently mmap doesn't go through usercopy, so
hardened usercopy won't Oops the kernel.

Pull cgroup fixes from Tejun Heo:
"This contains fixes for two long standing subtle bugs:
- kthread_bind() on a new kthread binds it to specific CPUs and
prevents userland from messing with the affinity or cgroup
membership. Unfortunately, for cgroup membership, there's a window
between kthread creation and kthread_bind*() invocation where the
kthread can be moved into a non-root cgroup by userland.
Depending on what controllers are in effect, this can assign the
kthread unexpected attributes. For example, in the reported case,
workqueue workers ended up in a non-root cpuset cgroups and had
their CPU affinities overridden. This broke workqueue invariants
and led to workqueue stalls.
Fixed by closing the window between kthread creation and
kthread_bind() as suggested by Oleg.

competing mount attempts to attach the same cgroup_root to two

"Two libata fixes.
One to disable hotplug on VT6420 which never worked properly. The
other reverts an earlier patch which disabled the second port on
SB600/700. There were some confusions due to earlier datasheets which
incorrectly indicated that the second port is not implemented on both
SB600 and 700"
* 'for-4.11-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/libata:
sata_via: Enable hotplug only on VT6421
Revert "pata_atiixp: Don't use unconnected secondary port on SB600/SB700"
Pull HID fixes from Jiri Kosina:
- revert of a commit that switched all Synaptics touchpads over to be
driven by hid-rmi. It turns out that this caused several user-visible
regressions, and therefore we revert back to the original state
before all the reported issues have been fixed.
- a new uclogic device ID addition, from Xiaolei Yu.
* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jikos/hid:
Revert "HID: rmi: Handle all Synaptics touchpads using hid-rmi"
HID: uclogic: add support for Ugee Tablet EX07S
KASAN reports that there is a use-after-free case of bio in btrfs_map_bio.
If we need to submit IOs to several disks at a time, the original bio
would get cloned and mapped to the destination disk, but we really should
use the original bio instead of a cloned bio to do the sanity check
because cloned bios are likely to be freed by its endio.
