Syzbot managed to trigger a use after free "KASAN: use-after-free Write
in hci_sock_bind". I have reviewed the code manually and one possibly
cause I have found is that we are not holding lock_sock(sk) when we do
the hci_dev_put(hdev) in hci_sock_release(). My theory is that the bind
and the release are racing against each other which results in this use
after free.

When a Linux hv_sock app tries to connect to a Service GUID on which no
host app is listening, a recent host (RS3+) sends a
CHANNELMSG_TL_CONNECT_RESULT (23) message to Linux and this triggers such
a warning:
unknown msgtype=23
WARNING: CPU: 2 PID: 0 at drivers/hv/vmbus_drv.c:1031 vmbus_on_msg_dpc
Actually Linux can safely ignore the message because the Linux app's
connect() will time out in 2 seconds: see VSOCK_DEFAULT_CONNECT_TIMEOUT
and vsock_stream_connect(). We don't bother to make use of the message
because: 1) it's only supported on recent hosts; 2) a non-trivial effort
is required to use the message in Linux, but the benefit is small.
So, let's not see the warning by silently ignoring the message.

fb_deferred_io_work() can access the vmbus ringbuffer by calling
fbdefio->deferred_io() -> synthvid_deferred_io() -> synthvid_update().
Because the vmbus ringbuffer is inaccessible between hvfb_suspend()
and hvfb_resume(), we must cancel info->deferred_work before calling
vmbus_close() and then reschedule it after we reopen the channel
in hvfb_resume().

Add suspend() and resume() functions so the Hyper-V virtual keyboard
can participate in VM hibernation.
Note that the keyboard is a "wakeup" device that could abort an in-progress
hibernation if there is keyboard event. No attempt is made to suppress this
behavior. If desired, a sysadmin can disable the keyboard as a wakeup device
using standard mechanisms such as:
echo disabled > /sys/bus/vmbus/drivers/hyperv_keyboard/XXX/power/wakeup
(where XXX is the device's GUID)

Current code has assumption that balloon request memory size aligns
with 2MB. But actually Hyper-V doesn't guarantee such alignment. When
balloon driver receives non-aligned balloon request, it produces warning
and balloon up more memory than requested in order to keep 2MB alignment.
Remove the warning and balloon up memory according to actual requested
memory size.

In fs_open(), 'vcc' is allocated through kmalloc() and assigned to
'atm_vcc->dev_data.' In the following execution, if an error occurs, e.g.,
there is no more free channel, an error code EBUSY or ENOMEM will be
returned. However, 'vcc' is not deallocated, leading to memory leaks. Note
that, in normal cases where fs_open() returns 0, 'vcc' will be deallocated
in fs_close(). But, if fs_open() fails, there is no guarantee that
fs_close() will be invoked.
To fix this issue, deallocate 'vcc' before the error code is returned.

As reported by Guilherme G. Piccoli:
---8<---8<---8<---
The rtc-cmos interrupt setting was changed in the commit 079062b28f
("rtc: cmos: prevent kernel warning on IRQ flags mismatch") in order
to allow shared interrupts; according to that commit's description,
some machine got kernel warnings due to the interrupt line being shared
between rtc-cmos and other hardware, and rtc-cmos didn't allow IRQ sharing
that time.
After the aforementioned commit though it was observed a huge increase
in lost HPET interrupts in some systems, observed through the following
kernel message:
[...] hpet1: lost 35 rtc interrupts
After investigation, it was narrowed down to the shared interrupts
usage when having the kernel option "irqpoll" enabled. In this case,
all IRQ handlers are called for non-timer interrupts, if such handlers
are setup in shared IRQ lines. The rtc-cmos IRQ handler could be set to
hpet_rtc_interrupt(), which will produce the kernel "lost interrupts"
message after doing work - lots of readl/writel to HPET registers, which
are known to be slow.
Although "irqpoll" is not a default kernel option, it's used in some contexts,
one being the kdump kernel (which is an already "impaired" kernel usually
running with 1 CPU available), so the performance burden could be considerable.
Also, the same issue would happen (in a shorter extent though) when using
"irqfixup" kernel option.
In a quick experiment, a virtual machine with uptime of 2 minutes produced
>300 calls to hpet_rtc_interrupt() when "irqpoll" was set, whereas without
sharing interrupts this number reduced to 1 interrupt. Machines with more
hardware than a VM should generate even more unnecessary HPET interrupts
in this scenario.
---8<---8<---8<---
After looking into the rtc-cmos driver history and DSDT table from
the Microsoft Surface 3, we may notice that Hans de Goede submitted
a correct fix (see dependency below). Thus, we simply revert
the culprit commit.

Boot-time processing often loops in the kernel longer than one might
prefer, which can prevent expedited grace periods from completing in
a timely manner. This in turn triggers a splat In nohz_full CPUs One
could argue that long-looping code should be fixed, but on the other hand,
boot time is a bit special.
This commit therefore removes the splat. Later commits will add the
splat back in, but in a way that removes false positives.

There is no separation between RDMA-CM wire format as it is declared in
IBTA and kernel logic which implements needed support. Such situation
causes to many mistakes in conversion between big-endian (wire format)
and CPU format used by kernel. It also mixes RDMA core code with
combination of uXX and beXX variables.
The idea that all accesses to IBA definitions will go through special
GET/SET macros to ensure that no conversion mistakes are made. The
shifting and masking required to read the value is automatically deduced
using the field offset description from the tables in the IBA
specification.
This starts with the CM MADs described in IBTA release 1.3 volume 1.
To confirm that the new macros behave the same as the old accessors a
self-test is included in this patch.
Each macro replacing a straightforward struct field compile-time tests
that the new field has the same offsetof() and width as the old field.
For the fields with accessor functions a runtime test, the 'all ones'
value is placed in a dummy message and read back in several ways to
confirm that both approaches give identical results.
Later patches in this series delete the self test.
This creates a tested table of new field name, old field name(s) and some
meta information like BE coding for the functions which will be used in
the next patches.

A user can change the operational GUID (a.k.a affective GUID) through
link/infiniband. Therefore it is preferred to return the currently set
GUID if it exists instead of the operational.
This way the PF can query which VF GUID will be set in the next bind. In
order to align with MAC address, zero is returned if administrative GUID
is not set.
For example, before setting administrative GUID:
$ ip link show

link/infiniband 00:00:00:08:fe:80:00:00:00:00:00:00:52:54:00:c0:fe:12:34:55 brd 00:ff:ff:ff:ff:12:40:1b:ff:ff:00:00:00:00:00:00:ff:ff:ff:ff

Then:
$ ip link set ib0 vf 0 node_guid 11:00:af:21:cb:05:11:00
$ ip link set ib0 vf 0 port_guid 22:11:af:21:cb:05:11:00

Kmemleak relies on specific symbols to register the read only data
during init (e.g. __start_ro_after_init).
Trying to build an XIP kernel on arm results in the linking error
reported below because when this option is selected read only data
after init are not allowed since .data is read only (.rodata).

To perform the reserve_crashkernel() operation kexec uses SECTION_SIZE to
find a memblock in a range.
SECTION_SIZE is not defined for nommu systems. Trying to compile kexec in
these conditions results in a build error:
linux/arch/arm/kernel/setup.c: In function ‘reserve_crashkernel’:
linux/arch/arm/kernel/setup.c:1016:25: error: ‘SECTION_SIZE’ undeclared
(first use in this function); did you mean ‘SECTIONS_WIDTH’?
crash_size, SECTION_SIZE);
^~~~~~~~~~~~

is reported only once for each function it appears in
linux/scripts/Makefile.build:265: recipe for target 'arch/arm/kernel/setup.o'
failed
Make KEXEC depend on MMU to fix the compilation issue.

As of commit ac7c3e4ff4 ("compiler: enable CONFIG_OPTIMIZE_INLINING
forcibly"), free_memmap() might not always be inlined, and thus is
triggering a section warning:
WARNING: vmlinux.o(.text.unlikely+0x904): Section mismatch in reference from the function free_memmap() to the function .meminit.text:memblock_free()
Mark it as __init, since the faller (free_unused_memmap) already is.
