Subject: [PATCH] bpf: sockmap: Require attach_bpf_fd when detaching a program
The sockmap code currently ignores the value of attach_bpf_fd when
detaching a program. This is contrary to the usual behaviour of
checking that attach_bpf_fd represents the currently attached
program.
Ensure that attach_bpf_fd is indeed the currently attached
program. It turns out that all sockmap selftests already do this,
which indicates that this is unlikely to cause breakage.

[PATCH RESEND] drm/imx: imx-ldb: Disable both channels for split mode in enc->disable()

Both of the two LVDS channels should be disabled for split mode
in the encoder's ->disable() callback, because they are enabled
in the encoder's ->enable() callback.

Re: [PATCH] block: fix splitting segments on boundary masks
by Tony Battersby
Although I was not originally involved in the development of these
patches, I recently came across them while looking over the source:
upstream commit 429120f3df2d ("block: fix splitting segments on boundary masks")
Cc: stable(a)vger.kernel.org # v5.1+
Fixes: dcebd755926b ("block: use bio_for_each_bvec() to compute multi-page bvec count")
upstream commit 4a2f704eb2d8 ("block: fix get_max_segment_size() overflow on 32bit arch")
Fixes: 429120f3df2d ("block: fix splitting segments on boundary masks")
https://www.spinics.net/lists/linux-block/msg48605.html
https://www.spinics.net/lists/linux-block/msg48959.html
The first patch mentions fixing problems with filesystem corruption, so
it seems important, but it has never been included in any -stable
kernel. Is there a specific reason these patches have been excluded
from -stable, or is it just a mistake?
These patches would be relevant to kernel versions 5.1 - 5.4, with 5.4.y
being the only active stable kernel series in that range. The patches
apply cleanly on top of 5.4.51.

[PATCH 4.9 4.14] x86/cpu: Move x86_cache_bits settings
by Suraj Jitindar Singh
This patch is to fix the backport of the upstream patch:
cc51e5428ea5 x86/speculation/l1tf: Increase l1tf memory limit for Nehalem+
When this was backported to the 4.9 and 4.14 stable branches the line
+ c->x86_cache_bits = c->x86_phys_bits;
was applied in the wrong place, being added to the
identify_cpu_without_cpuid() function instead of the get_cpu_cap()
function which it was correctly applied to in the 4.4 backport.
This means that x86_cache_bits is not set correctly resulting in the
following warning due to the cache bits being left uninitalised (zero).

printk: queue wake_up_klogd irq_work only if per-CPU areas are ready

Hello,
Commit ab6f762f0f53162d41 Linus' HEAD.
printk_deferred() does not make sure that it's safe to write to
per-CPU data, which causes problems when printk_deferred() is
invoked "too early", before per-CPU areas are initialized. There
are multiple bug reports, e.g.

Subject: [PATCH] drm/i915: Recalculate FBC w/a stride when needed
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Currently we're failing to recalculate the gen9 FBC w/a stride
unless something more drastic than just the modifier itself has
changed. This often leaves us with FBC enabled with the linear
fbdev framebuffer without the w/a stride enabled. That will cause
an immediate underrun and FBC will get promptly disabled.
Fix the problem by checking if the w/a stride is about to change,
and go through the full dance if so. This part of the FBC code
is still pretty much a disaster and will need lots more work.
But this should at least fix the immediate issue.
v2: Deactivate FBC when the modifier changes since that will
likely require resetting the w/a CFB stride

Subject: [PATCH] irqdomain/treewide: Keep firmware node unconditionally
allocated
Quite some non OF/ACPI users of irqdomains allocate firmware nodes of type
IRQCHIP_FWNODE_NAMED or IRQCHIP_FWNODE_NAMED_ID and free them right after
creating the irqdomain. The only purpose of these FW nodes is to convey
name information. When this was introduced the core code did not store the
pointer to the node in the irqdomain. A recent change stored the firmware
node pointer in irqdomain for other reasons and missed to notice that the
usage sites which do the alloc_fwnode/create_domain/free_fwnode sequence
are broken by this. Storing a dangling pointer is dangerous itself, but in
case that the domain is destroyed later on this leads to a double free.
Remove the freeing of the firmware node after creating the irqdomain from
all affected call sites to cure this.
Fixes: 711419e504eb ("irqdomain: Add the missing assignment of domain->fwnode for named fwnode")

Subject: [PATCH] irqdomain/treewide: Keep firmware node unconditionally
allocated
Quite some non OF/ACPI users of irqdomains allocate firmware nodes of type
IRQCHIP_FWNODE_NAMED or IRQCHIP_FWNODE_NAMED_ID and free them right after
creating the irqdomain. The only purpose of these FW nodes is to convey
name information. When this was introduced the core code did not store the
pointer to the node in the irqdomain. A recent change stored the firmware
node pointer in irqdomain for other reasons and missed to notice that the
usage sites which do the alloc_fwnode/create_domain/free_fwnode sequence
are broken by this. Storing a dangling pointer is dangerous itself, but in
case that the domain is destroyed later on this leads to a double free.
Remove the freeing of the firmware node after creating the irqdomain from
all affected call sites to cure this.
Fixes: 711419e504eb ("irqdomain: Add the missing assignment of domain->fwnode for named fwnode")

Subject: [PATCH] drm/i915/gt: Only swap to a random sibling once upon creation
The danger in switching at random upon intel_context_pin is that the
context may still actually be inflight, as it will not be scheduled out
until a context switch after it is complete -- that may be a long time
after we do a final intel_context_unpin.

I tried this first patch, and it doesn't apply to the 5.4.y tree, so are
you sure you tried these yourself?
If so, please send a series of backported patches that you have
successfully tested, or if a patch applies cleanly, just the git id.

[PATCH][STABLE 4.9] irqchip/gic: Atomically update affinity
by Marc Zyngier
Commit 005c34ae4b44f085120d7f371121ec7ded677761 upstream.
The GIC driver uses a RMW sequence to update the affinity, and
relies on the gic_lock_irqsave/gic_unlock_irqrestore sequences
to update it atomically.
But these sequences only expand into anything meaningful if
the BL_SWITCHER option is selected, which almost never happens.
It also turns out that using a RMW and locks is just as silly,
as the GIC distributor supports byte accesses for the GICD_TARGETRn
registers, which when used make the update atomic by definition.
Drop the terminally broken code and replace it by a byte write.
Fixes: 04c8b0f82c7d ("irqchip/gic: Make locking a BL_SWITCHER only feature")

[PATCH v4.19] sched/fair: handle case of task_h_load() returning 0
by Vincent Guittot
[ Upstream commit 01cfcde9c26d8555f0e6e9aea9d6049f87683998 ]
task_h_load() can return 0 in some situations like running stress-ng
mmapfork, which forks thousands of threads, in a sched group on a 224 cores
system. The load balance doesn't handle this correctly because
env->imbalance never decreases and it will stop pulling tasks only after
reaching loop_max, which can be equal to the number of running tasks of
the cfs. Make sure that imbalance will be decreased by at least 1.
We can't simply ensure that task_h_load() returns at least one because it
would imply to handle underflow in other places.

return
Although we zero the upper bits of x0 on entry to the kernel from an
AArch32 task, we do not clear them on the exception return path and can
therefore expose 64-bit sign extended syscall return values to userspace
via interfaces such as the 'perf_regs' ABI, which deal exclusively with
64-bit registers.
Explicitly clear the upper 32 bits of x0 on return from a compat system

Subject: [PATCH] arm64: ptrace: Consistently use pseudo-singlestep exceptions
Although the arm64 single-step state machine can be fast-forwarded in
cases where we wish to generate a SIGTRAP without actually executing an
instruction, this has two major limitations outside of simply skipping
an instruction due to emulation.
1. Stepping out of a ptrace signal stop into a signal handler where
SIGTRAP is blocked. Fast-forwarding the stepping state machine in
this case will result in a forced SIGTRAP, with the handler reset to
SIG_DFL.
2. The hardware implicitly fast-forwards the state machine when executing
an SVC instruction for issuing a system call. This can interact badly
with subsequent ptrace stops signalled during the execution of the
system call (e.g. SYSCALL_EXIT or seccomp traps), as they may corrupt
the stepping state by updating the PSTATE for the tracee.
Resolve both of these issues by injecting a pseudo-singlestep exception
on entry to a signal handler and also on return to userspace following a
system call.

Subject: [PATCH] arm64: ptrace: Consistently use pseudo-singlestep exceptions
Although the arm64 single-step state machine can be fast-forwarded in
cases where we wish to generate a SIGTRAP without actually executing an
instruction, this has two major limitations outside of simply skipping
an instruction due to emulation.
1. Stepping out of a ptrace signal stop into a signal handler where
SIGTRAP is blocked. Fast-forwarding the stepping state machine in
this case will result in a forced SIGTRAP, with the handler reset to
SIG_DFL.
2. The hardware implicitly fast-forwards the state machine when executing
an SVC instruction for issuing a system call. This can interact badly
with subsequent ptrace stops signalled during the execution of the
system call (e.g. SYSCALL_EXIT or seccomp traps), as they may corrupt
the stepping state by updating the PSTATE for the tracee.
Resolve both of these issues by injecting a pseudo-singlestep exception
on entry to a signal handler and also on return to userspace following a
system call.

[For-STABLE] thermal/drivers/cpufreq_cooling: Fix wrong frequency converted from power
by Viresh Kumar
From: Finley Xiao <finley.xiao(a)rock-chips.com>
commit 371a3bc79c11b707d7a1b7a2c938dc3cc042fffb upstream.
The function cpu_power_to_freq is used to find a frequency and set the
cooling device to consume at most the power to be converted. For example,
if the power to be converted is 80mW, and the em table is as follow.
struct em_cap_state table[] = {
/* KHz mW */
{ 1008000, 36, 0 },
{ 1200000, 49, 0 },
{ 1296000, 59, 0 },
{ 1416000, 72, 0 },
{ 1512000, 86, 0 },
};
The target frequency should be 1416000KHz, not 1512000KHz.

Hi Greg,
I am resending this as I got your emails of this failing on 4.14, 4.19
and 5.4. This should be applied to all three of them.
@Finley: I hope I have done it correctly, please do check it as this
required me to rewrite the code to adapt to previous kernels.

Subject: [PATCH] dmabuf: use spinlock to access dmabuf->name
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
There exists a sleep-while-atomic bug while accessing the dmabuf->name
under mutex in the dmabuffs_dname(). This is caused from the SELinux
permissions checks on a process where it tries to validate the inherited
files from fork() by traversing them through iterate_fd() (which
traverse files under spin_lock) and call
match_file(security/selinux/hooks.c) where the permission checks happen.
This audit information is logged using dump_common_audit_data() where it
calls d_path() to get the file path name. If the file check happen on
the dmabuf's fd, then it ends up in ->dmabuffs_dname() and use mutex to
access dmabuf->name. The flow will be like below:
flush_unauthorized_files()
iterate_fd()
spin_lock() --> Start of the atomic section.
match_file()
file_has_perm()
avc_has_perm()
avc_audit()
slow_avc_audit()
common_lsm_audit()
dump_common_audit_data()
audit_log_d_path()
d_path()
dmabuffs_dname()
mutex_lock()--> Sleep while atomic.
Call trace captured (on 4.19 kernels) is below:
___might_sleep+0x204/0x208
__might_sleep+0x50/0x88
__mutex_lock_common+0x5c/0x1068
__mutex_lock_common+0x5c/0x1068
mutex_lock_nested+0x40/0x50
dmabuffs_dname+0xa0/0x170
d_path+0x84/0x290
audit_log_d_path+0x74/0x130
common_lsm_audit+0x334/0x6e8
slow_avc_audit+0xb8/0xf8
avc_has_perm+0x154/0x218
file_has_perm+0x70/0x180
match_file+0x60/0x78
iterate_fd+0x128/0x168
selinux_bprm_committing_creds+0x178/0x248
security_bprm_committing_creds+0x30/0x48
install_exec_creds+0x1c/0x68
load_elf_binary+0x3a4/0x14e0
search_binary_handler+0xb0/0x1e0
So, use spinlock to access dmabuf->name to avoid sleep-while-atomic.

Subject: [PATCH] intel_th: Add driver infrastructure for Intel(R) Trace Hub
devices
Intel(R) Trace Hub (TH) is a set of hardware blocks (subdevices) that
produce, switch and output trace data from multiple hardware and
software sources over several types of trace output ports encoded
in System Trace Protocol (MIPI STPv2) and is intended to perform
full system debugging.
For these subdevices, we create a bus, where they can be discovered
and configured by userspace software.
This patch creates this bus infrastructure, three types of devices
(source, output, switch), resource allocation, some callback mechanisms
to facilitate communication between the subdevices' drivers and some
common sysfs attributes.

+Intel(R) Trace Hub (TH)
+=======================
+
+Overview
+--------
+
+Intel(R) Trace Hub (TH) is a set of hardware blocks that produce,
+switch and output trace data from multiple hardware and software
+sources over several types of trace output ports encoded in System
+Trace Protocol (MIPI STPv2) and is intended to perform full system
+debugging. For more information on the hardware, see Intel(R) Trace
+Hub developer's manual [1].
+
+It consists of trace sources, trace destinations (outputs) and a
+switch (Global Trace Hub, GTH). These devices are placed on a bus of
+their own ("intel_th"), where they can be discovered and configured
+via sysfs attributes.
+
+Currently, the following Intel TH subdevices (blocks) are supported:
+ - Software Trace Hub (STH), trace source, which is a System Trace
+ Module (STM) device,
+ - Memory Storage Unit (MSU), trace output, which allows storing
+ trace hub output in system memory,
+ - Parallel Trace Interface output (PTI), trace output to an external
+ debug host via a PTI port,
+ - Global Trace Hub (GTH), which is a switch and a central component
+ of Intel(R) Trace Hub architecture.
+
+Common attributes for output devices are described in
+Documentation/ABI/testing/sysfs-bus-intel_th-output-devices, the most
+notable of them is "active", which enables or disables trace output
+into that particular output device.
+
+GTH allows directing different STP masters into different output ports
+via its "masters" attribute group. More detailed GTH interface
+description is at Documentation/ABI/testing/sysfs-bus-intel_th-devices-gth.
+
+STH registers an stm class device, through which it provides interface
+to userspace and kernelspace software trace sources. See
+Documentation/tracing/stm.txt for more information on that.
+
+MSU can be configured to collect trace data into a system memory
+buffer, which can later on be read from its device nodes via read() or
+mmap() interface.
+
+On the whole, Intel(R) Trace Hub does not require any special
+userspace software to function; everything can be configured, started
+and collected via sysfs attributes, and device nodes.
+

+
+Bus and Subdevices
+------------------
+
+For each Intel TH device in the system a bus of its own is
+created and assigned an id number that reflects the order in which TH
+devices were emumerated. All TH subdevices (devices on intel_th bus)
+begin with this id: 0-gth, 0-msc0, 0-msc1, 0-pti, 0-sth, which is
+followed by device's name and an optional index.
+
+Output devices also get a device node in /dev/intel_thN, where N is
+the Intel TH device id. For example, MSU's memory buffers, when
+allocated, are accessible via /dev/intel_th0/msc{0,1}.
+
+Quick example
+-------------
+
+# figure out which GTH port is the first memory controller:
+
+$ cat /sys/bus/intel_th/devices/0-msc0/port
+0
+
+# looks like it's port 0, configure master 33 to send data to port 0:
+
+$ echo 0 > /sys/bus/intel_th/devices/0-gth/masters/33
+
+# allocate a 2-windowed multiblock buffer on the first memory
+# controller, each with 64 pages:
+
+$ echo multi > /sys/bus/intel_th/devices/0-msc0/mode
+$ echo 64,64 > /sys/bus/intel_th/devices/0-msc0/nr_pages
+
+# enable wrapping for this controller, too:
+
+$ echo 1 > /sys/bus/intel_th/devices/0-msc0/wrap
+
+# and enable tracing into this port:
+
+$ echo 1 > /sys/bus/intel_th/devices/0-msc0/active
+
+# .. send data to master 33, see stm.txt for more details ..
+# .. wait for traces to pile up ..
+# .. and stop the trace:
+
+$ echo 0 > /sys/bus/intel_th/devices/0-msc0/active
+
+# and now you can collect the trace from the device node:
+
+$ cat /dev/intel_th0/msc0 > my_stp_trace

Subject: [PATCH] intel_th: Add driver infrastructure for Intel(R) Trace Hub
devices
Intel(R) Trace Hub (TH) is a set of hardware blocks (subdevices) that
produce, switch and output trace data from multiple hardware and
software sources over several types of trace output ports encoded
in System Trace Protocol (MIPI STPv2) and is intended to perform
full system debugging.
For these subdevices, we create a bus, where they can be discovered
and configured by userspace software.
This patch creates this bus infrastructure, three types of devices
(source, output, switch), resource allocation, some callback mechanisms
to facilitate communication between the subdevices' drivers and some
common sysfs attributes.

+Intel(R) Trace Hub (TH)
+=======================
+
+Overview
+--------
+
+Intel(R) Trace Hub (TH) is a set of hardware blocks that produce,
+switch and output trace data from multiple hardware and software
+sources over several types of trace output ports encoded in System
+Trace Protocol (MIPI STPv2) and is intended to perform full system
+debugging. For more information on the hardware, see Intel(R) Trace
+Hub developer's manual [1].
+
+It consists of trace sources, trace destinations (outputs) and a
+switch (Global Trace Hub, GTH). These devices are placed on a bus of
+their own ("intel_th"), where they can be discovered and configured
+via sysfs attributes.
+
+Currently, the following Intel TH subdevices (blocks) are supported:
+ - Software Trace Hub (STH), trace source, which is a System Trace
+ Module (STM) device,
+ - Memory Storage Unit (MSU), trace output, which allows storing
+ trace hub output in system memory,
+ - Parallel Trace Interface output (PTI), trace output to an external
+ debug host via a PTI port,
+ - Global Trace Hub (GTH), which is a switch and a central component
+ of Intel(R) Trace Hub architecture.
+
+Common attributes for output devices are described in
+Documentation/ABI/testing/sysfs-bus-intel_th-output-devices, the most
+notable of them is "active", which enables or disables trace output
+into that particular output device.
+
+GTH allows directing different STP masters into different output ports
+via its "masters" attribute group. More detailed GTH interface
+description is at Documentation/ABI/testing/sysfs-bus-intel_th-devices-gth.
+
+STH registers an stm class device, through which it provides interface
+to userspace and kernelspace software trace sources. See
+Documentation/tracing/stm.txt for more information on that.
+
+MSU can be configured to collect trace data into a system memory
+buffer, which can later on be read from its device nodes via read() or
+mmap() interface.
+
+On the whole, Intel(R) Trace Hub does not require any special
+userspace software to function; everything can be configured, started
+and collected via sysfs attributes, and device nodes.
+
+[1] https://software.intel.com/sites/default/files/managed/d3/3c/intel-th-devel…
+
+Bus and Subdevices
+------------------
+
+For each Intel TH device in the system a bus of its own is
+created and assigned an id number that reflects the order in which TH
+devices were emumerated. All TH subdevices (devices on intel_th bus)
+begin with this id: 0-gth, 0-msc0, 0-msc1, 0-pti, 0-sth, which is
+followed by device's name and an optional index.
+
+Output devices also get a device node in /dev/intel_thN, where N is
+the Intel TH device id. For example, MSU's memory buffers, when
+allocated, are accessible via /dev/intel_th0/msc{0,1}.
+
+Quick example
+-------------
+
+# figure out which GTH port is the first memory controller:
+
+$ cat /sys/bus/intel_th/devices/0-msc0/port
+0
+
+# looks like it's port 0, configure master 33 to send data to port 0:
+
+$ echo 0 > /sys/bus/intel_th/devices/0-gth/masters/33
+
+# allocate a 2-windowed multiblock buffer on the first memory
+# controller, each with 64 pages:
+
+$ echo multi > /sys/bus/intel_th/devices/0-msc0/mode
+$ echo 64,64 > /sys/bus/intel_th/devices/0-msc0/nr_pages
+
+# enable wrapping for this controller, too:
+
+$ echo 1 > /sys/bus/intel_th/devices/0-msc0/wrap
+
+# and enable tracing into this port:
+
+$ echo 1 > /sys/bus/intel_th/devices/0-msc0/active
+
+# .. send data to master 33, see stm.txt for more details ..
+# .. wait for traces to pile up ..
+# .. and stop the trace:
+
+$ echo 0 > /sys/bus/intel_th/devices/0-msc0/active
+
+# and now you can collect the trace from the device node:
+
+$ cat /dev/intel_th0/msc0 > my_stp_trace

+ Intel(R) Trace Hub (TH) is a set of hardware blocks (subdevices) that
+ produce, switch and output trace data from multiple hardware and
+ software sources over several types of trace output ports encoded
+ in System Trace Protocol (MIPI STPv2) and is intended to perform
+ full system debugging.
+
+ This option enables intel_th bus and common code used by TH
+ subdevices to interact with each other and hardware and for
+ platform glue layers to drive Intel TH devices.

+ Say Y here to enable Intel(R) Trace Hub controller support.

Subject: [PATCH] intel_th: Add driver infrastructure for Intel(R) Trace Hub
devices
Intel(R) Trace Hub (TH) is a set of hardware blocks (subdevices) that
produce, switch and output trace data from multiple hardware and
software sources over several types of trace output ports encoded
in System Trace Protocol (MIPI STPv2) and is intended to perform
full system debugging.
For these subdevices, we create a bus, where they can be discovered
and configured by userspace software.
This patch creates this bus infrastructure, three types of devices
(source, output, switch), resource allocation, some callback mechanisms
to facilitate communication between the subdevices' drivers and some
common sysfs attributes.

+Intel(R) Trace Hub (TH)
+=======================
+
+Overview
+--------
+
+Intel(R) Trace Hub (TH) is a set of hardware blocks that produce,
+switch and output trace data from multiple hardware and software
+sources over several types of trace output ports encoded in System
+Trace Protocol (MIPI STPv2) and is intended to perform full system
+debugging. For more information on the hardware, see Intel(R) Trace
+Hub developer's manual [1].
+
+It consists of trace sources, trace destinations (outputs) and a
+switch (Global Trace Hub, GTH). These devices are placed on a bus of
+their own ("intel_th"), where they can be discovered and configured
+via sysfs attributes.
+
+Currently, the following Intel TH subdevices (blocks) are supported:
+ - Software Trace Hub (STH), trace source, which is a System Trace
+ Module (STM) device,
+ - Memory Storage Unit (MSU), trace output, which allows storing
+ trace hub output in system memory,
+ - Parallel Trace Interface output (PTI), trace output to an external
+ debug host via a PTI port,
+ - Global Trace Hub (GTH), which is a switch and a central component
+ of Intel(R) Trace Hub architecture.
+
+Common attributes for output devices are described in
+Documentation/ABI/testing/sysfs-bus-intel_th-output-devices, the most
+notable of them is "active", which enables or disables trace output
+into that particular output device.
+
+GTH allows directing different STP masters into different output ports
+via its "masters" attribute group. More detailed GTH interface
+description is at Documentation/ABI/testing/sysfs-bus-intel_th-devices-gth.
+
+STH registers an stm class device, through which it provides interface
+to userspace and kernelspace software trace sources. See
+Documentation/tracing/stm.txt for more information on that.
+
+MSU can be configured to collect trace data into a system memory
+buffer, which can later on be read from its device nodes via read() or
+mmap() interface.
+
+On the whole, Intel(R) Trace Hub does not require any special
+userspace software to function; everything can be configured, started
+and collected via sysfs attributes, and device nodes.
+
+[1] https://software.intel.com/sites/default/files/managed/d3/3c/intel-th-devel…
+
+Bus and Subdevices
+------------------
+
+For each Intel TH device in the system a bus of its own is
+created and assigned an id number that reflects the order in which TH
+devices were emumerated. All TH subdevices (devices on intel_th bus)
+begin with this id: 0-gth, 0-msc0, 0-msc1, 0-pti, 0-sth, which is
+followed by device's name and an optional index.
+
+Output devices also get a device node in /dev/intel_thN, where N is
+the Intel TH device id. For example, MSU's memory buffers, when
+allocated, are accessible via /dev/intel_th0/msc{0,1}.
+
+Quick example
+-------------
+
+# figure out which GTH port is the first memory controller:
+
+$ cat /sys/bus/intel_th/devices/0-msc0/port
+0
+
+# looks like it's port 0, configure master 33 to send data to port 0:
+
+$ echo 0 > /sys/bus/intel_th/devices/0-gth/masters/33
+
+# allocate a 2-windowed multiblock buffer on the first memory
+# controller, each with 64 pages:
+
+$ echo multi > /sys/bus/intel_th/devices/0-msc0/mode
+$ echo 64,64 > /sys/bus/intel_th/devices/0-msc0/nr_pages
+
+# enable wrapping for this controller, too:
+
+$ echo 1 > /sys/bus/intel_th/devices/0-msc0/wrap
+
+# and enable tracing into this port:
+
+$ echo 1 > /sys/bus/intel_th/devices/0-msc0/active
+
+# .. send data to master 33, see stm.txt for more details ..
+# .. wait for traces to pile up ..
+# .. and stop the trace:
+
+$ echo 0 > /sys/bus/intel_th/devices/0-msc0/active
+
+# and now you can collect the trace from the device node:
+
+$ cat /dev/intel_th0/msc0 > my_stp_trace

Subject: [PATCH] timers: Forward the wheel clock whenever possible
The wheel clock is stale when a CPU goes into a long idle sleep. This has the
side effect that timers which are queued end up in the outer wheel levels.
That results in coarser granularity.
To solve this, we keep track of the idle state and forward the wheel clock
whenever possible.

[PATCH] pci: tegra: Revert raw_violation_fixup for tegra124
by Nicolas Chauvet
As reported in https://bugzilla.kernel.org/206217 , raw_violation_fixup
is causing more harm than good in some common use-cases.
This patch is a partial revert of the 191cd6fb5 commit:
"PCI: tegra: Add SW fixup for RAW violations"
that was first introduced in 5.3-rc1 kernel.
This fix the following regression since then.
* Description:
When both the NIC and MMC are used one can see the following message:
NETDEV WATCHDOG: enp1s0 (r8169): transmit queue 0 timed out
and
pcieport 0000:00:02.0: AER: Uncorrected (Non-Fatal) error received: 0000:01:00.0
r8169 0000:01:00.0: AER: PCIe Bus Error: severity=Uncorrected (Non-Fatal), type=Transaction Layer, (Requester ID)
r8169 0000:01:00.0: AER: device [10ec:8168] error status/mask=00004000/00400000
r8169 0000:01:00.0: AER: [14] CmpltTO (First)
r8169 0000:01:00.0: AER: can't recover (no error_detected callback)
pcieport 0000:00:02.0: AER: device recovery failed
After that, the ethernet NIC isn't functional anymore even after reloading
the r8169 module.
After a reboot, this is reproducible by copying a large file over the
NIC to the MMC.
For some reasons this cannot be reproduced when the same file is copied
to a tmpfs.
* Little background on the fixup, by Manikanta Maddireddy:
"In the internal testing with dGPU on Tegra124, CmplTO is reported by
dGPU. This happened because FIFO queue in AFI(AXI to PCIe) module
get full by upstream posted writes. Back to back upstream writes
interleaved with infrequent reads, triggers RAW violation and CmpltTO.
This is fixed by reducing the posted write credits and by changing
updateFC timer frequency. These settings are fixed after stress test.
In the current case, RTL NIC is also reporting CmplTO. These settings
seems to be aggravating the issue instead of fixing it."

Aborted tests
-------------
Tests that didn't complete running successfully are marked with ⚡⚡⚡.
If this was caused by an infrastructure issue, we try to mark that
explicitly in the report.
Waived tests
------------
If the test run included waived tests, they are marked with 🚧. Such tests are
executed but their results are not taken into account. Tests are waived when
their results are not reliable enough, e.g. when they're just introduced or are
being fixed.
Testing timeout
---------------
We aim to provide a report within reasonable timeframe. Tests that haven't
finished running yet are marked with ⏱.

[PATCH 1/3] fuse: use ->reconfigure() instead of ->remount_fs()
by Miklos Szeredi
s_op->remount_fs() is only called from legacy_reconfigure(), which is not
used after being converted to the new API.
Convert to using ->reconfigure(). This restores the previous behavior of
syncing the filesystem and rejecting MS_MANDLOCK on remount.

[PATCH 5.4] sched/fair: handle case of task_h_load() returning 0
by Vincent Guittot
[ Upstream commit 01cfcde9c26d8555f0e6e9aea9d6049f87683998 ]
task_h_load() can return 0 in some situations like running stress-ng
mmapfork, which forks thousands of threads, in a sched group on a 224 cores
system. The load balance doesn't handle this correctly because
env->imbalance never decreases and it will stop pulling tasks only after
reaching loop_max, which can be equal to the number of running tasks of
the cfs. Make sure that imbalance will be decreased by at least 1.
misfit task is the other feature that doesn't handle correctly such
situation although it's probably more difficult to face the problem
because of the smaller number of CPUs and running tasks on heterogenous
system.
We can't simply ensure that task_h_load() returns at least one because it
would imply to handle underflow in other places.

to my staging git tree which can be found at
git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging.git
in the staging-linus branch.
The patch will show up in the next release of the linux-next tree
(usually sometime within the next 24 hours during the week.)
The patch will hopefully also be merged in Linus's tree for the
next -rc kernel release.
If you have any questions about this process, please let me know.

The `INSN_CONFIG` comedi instruction with sub-instruction code

used as a right shift amount for other bitmask values without being
checked. Shift amounts greater than or equal to 32 will result in
undefined behavior. Add code to deal with this.

patch "staging: comedi: addi_apci_1032: check INSN_CONFIG_DIGITAL_TRIG shift" added to staging-linus
by gregkh＠linuxfoundation.org
This is a note to let you know that I've just added the patch titled
staging: comedi: addi_apci_1032: check INSN_CONFIG_DIGITAL_TRIG shift
to my staging git tree which can be found at
git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging.git
in the staging-linus branch.
The patch will show up in the next release of the linux-next tree
(usually sometime within the next 24 hours during the week.)
The patch will hopefully also be merged in Linus's tree for the
next -rc kernel release.
If you have any questions about this process, please let me know.

Subject: staging: comedi: addi_apci_1032: check INSN_CONFIG_DIGITAL_TRIG shift
The `INSN_CONFIG` comedi instruction with sub-instruction code
`INSN_CONFIG_DIGITAL_TRIG` includes a base channel in `data[3]`. This is
used as a right shift amount for other bitmask values without being
checked. Shift amounts greater than or equal to 32 will result in
undefined behavior. Add code to deal with this.

Subject: staging: comedi: ni_6527: fix INSN_CONFIG_DIGITAL_TRIG support
`ni6527_intr_insn_config()` processes `INSN_CONFIG` comedi instructions
for the "interrupt" subdevice. When `data[0]` is
`INSN_CONFIG_DIGITAL_TRIG` it is configuring the digital trigger. When
`data[2]` is `COMEDI_DIGITAL_TRIG_ENABLE_EDGES` it is configuring rising
and falling edge detection for the digital trigger, using a base channel
number (or shift amount) in `data[3]`, a rising edge bitmask in
`data[4]` and falling edge bitmask in `data[5]`.
If the base channel number (shift amount) is greater than or equal to
the number of channels (24) of the digital input subdevice, there are no
changes to the rising and falling edges, so the mask of channels to be
changed can be set to 0, otherwise the mask of channels to be changed,
and the rising and falling edge bitmasks are shifted by the base channel
number before calling `ni6527_set_edge_detection()` to change the
appropriate registers. Unfortunately, the code is comparing the base
channel (shift amount) to the interrupt subdevice's number of channels
(1) instead of the digital input subdevice's number of channels (24).
Fix it by comparing to 32 because all shift amounts for an `unsigned
int` must be less than that and everything from bit 24 upwards is
ignored by `ni6527_set_edge_detection()` anyway.

[PATCH v3] ARM: dts: imx6qdl-icore: Fix OTG_ID pin and sdcard detect
by Suniel Mahesh
From: Michael Trimarchi <michael(a)amarulasolutions.com>
The current pin muxing scheme muxes GPIO_1 pad for USB_OTG_ID
because of which when card is inserted, usb otg is enumerated
and the card is never detected.

[PATCH v3] x86/ioperm: Fix io bitmap invalidation on Xen PV
by Andy Lutomirski
tss_invalidate_io_bitmap() wasn't wired up properly through the pvop
machinery, so the TSS and Xen's io bitmap would get out of sync
whenever disabling a valid io bitmap.
Add a new pvop for tss_invalidate_io_bitmap() to fix it.
This is XSA-329.

[PATCH] PCI: tegra: Revert tegra124 raw_violation_fixup
by Nicolas Chauvet
As reported in https://bugzilla.kernel.org/206217 , raw_violation_fixup
is causing more harm than good in some common use-cases.
This patch is a partial revert of commit:
191cd6fb5d2c ("PCI: tegra: Add SW fixup for RAW violations")
that was first introduced in 5.3-rc1 kernel. This fix the following
regression since then.
* Description:
When both the NIC and MMC are used one can see the following message:
NETDEV WATCHDOG: enp1s0 (r8169): transmit queue 0 timed out
and
pcieport 0000:00:02.0: AER: Uncorrected (Non-Fatal) error received: 0000:01:00.0
r8169 0000:01:00.0: AER: PCIe Bus Error: severity=Uncorrected (Non-Fatal), type=Transaction Layer, (Requester ID)
r8169 0000:01:00.0: AER: device [10ec:8168] error status/mask=00004000/00400000
r8169 0000:01:00.0: AER: [14] CmpltTO (First)
r8169 0000:01:00.0: AER: can't recover (no error_detected callback)
pcieport 0000:00:02.0: AER: device recovery failed
After that, the ethernet NIC isn't functional anymore even after
reloading the r8169 module. After a reboot, this is reproducible by
copying a large file over the NIC to the MMC.
For some reason this is not reproducible when files are copied to a tmpfs.
* Little background on the fixup, by Manikanta Maddireddy:
"In the internal testing with dGPU on Tegra124, CmplTO is reported by
dGPU. This happened because FIFO queue in AFI(AXI to PCIe) module
get full by upstream posted writes. Back to back upstream writes
interleaved with infrequent reads, triggers RAW violation and CmpltTO.
This is fixed by reducing the posted write credits and by changing
updateFC timer frequency. These settings are fixed after stress test.
In the current case, RTL NIC is also reporting CmplTO. These settings
seems to be aggravating the issue instead of fixing it."

genirq/affinity: Handle affinity setting on inactive interrupts correctly
Setting interrupt affinity on inactive interrupts is inconsistent when
hierarchical irq domains are enabled. The core code should just store the
affinity and not call into the irq chip driver for inactive interrupts
because the chip drivers may not be in a state to handle such requests.
X86 has a hacky workaround for that but all other irq chips have not which
causes problems e.g. on GIC V3 ITS.
Instead of adding more ugly hacks all over the place, solve the problem in
the core code. If the affinity is set on an inactive interrupt then:
- Store it in the irq descriptors affinity mask
- Update the effective affinity to reflect that so user space has
a consistent view
- Don't call into the irq chip driver
This is the core equivalent of the X86 workaround and works correctly
because the affinity setting is established in the irq chip when the
interrupt is activated later on.
Note, that this is only effective when hierarchical irq domains are enabled
by the architecture. Doing it unconditionally would break legacy irq chip
implementations.
For hierarchial irq domains this works correctly as none of the drivers can
have a dependency on affinity setting in inactive state by design.
Remove the X86 workaround as it is not longer required.

[PATCH 01/12] timer: Fix wheel index calculation on last level
by Frederic Weisbecker
When an expiration delta falls into the last level of the wheel, we want
to compare that delta against the maximum possible delay and reduce our
delta to fit in if necessary.
However instead of comparing the delta against the maximum, we are
comparing the actual expiry against the maximum. Then instead of fixing
the delta to fit in, we set the maximum delta as the expiry value.
This can result in various undesired outcomes, the worst possible one
being a timer expiring 15 days ahead to fire immediately.

[PATCH 03/13] fs/kernel_read_file: Remove FIRMWARE_EFI_EMBEDDED enum
by Kees Cook
The "FIRMWARE_EFI_EMBEDDED" enum is a "where", not a "what". It
should not be distinguished separately from just "FIRMWARE", as this
confuses the LSMs about what is being loaded. Additionally, there was
no actual validation of the firmware contents happening.

Aborted tests
-------------
Tests that didn't complete running successfully are marked with ⚡⚡⚡.
If this was caused by an infrastructure issue, we try to mark that
explicitly in the report.
Waived tests
------------
If the test run included waived tests, they are marked with 🚧. Such tests are
executed but their results are not taken into account. Tests are waived when
their results are not reliable enough, e.g. when they're just introduced or are
being fixed.
Testing timeout
---------------
We aim to provide a report within reasonable timeframe. Tests that haven't
finished running yet are marked with ⏱.

[PATCH 01/13] firmware_loader: EFI firmware loader must handle pre-allocated buffer
by Kees Cook
The EFI platform firmware fallback would clobber any pre-allocated
buffers. Instead, correctly refuse to reallocate when too small (as
already done in the sysfs fallback), or perform allocation normally
when needed.
Fixes: e4c2c0ff00ec ("firmware: Add new platform fallback mechanism and firm ware_request_platform()")
Cc: stable(a)vger.kernel.org
Signed-off-by: Kees Cook <keescook(a)chromium.org>
---
To aid in backporting, this change is made before moving
kernel_read_file() to separate header/source files.

[PATCH v2 1/2] bcache: avoid nr_stripes overflow in bcache_device_init()
by Coly Li
For some block devices which large capacity (e.g. 8TB) but small io_opt
size (e.g. 8 sectors), in bcache_device_init() the stripes number calcu-
lated by,
DIV_ROUND_UP_ULL(sectors, d->stripe_size);
might be overflow to the unsigned int bcache_device->nr_stripes.
This patch uses the uint64_t variable to store DIV_ROUND_UP_ULL()
and after the value is checked to be available in unsigned int range,
sets it to bache_device->nr_stripes. Then the overflow is avoided.

[PATCH] btrfs: add missing check for nocow and compression inode flags
by David Sterba
User Forza reported on IRC that some invalid combinations of file
attributes are accepted by chattr.
The NODATACOW and compression file flags/attributes are mutually
exclusive, but they could be set by 'chattr +c +C' on an empty file. The
nodatacow will be in effect because it's checked first in
btrfs_run_delalloc_range.
Extend the flag validation to catch the following cases:
- input flags are conflicting
- old and new flags are conflicting
- initialize the local variable with inode flags after inode ls locked

Subject: [PATCH] iio:humidity:hts221 Fix alignment and data leak issues
One of a class of bugs pointed out by Lars in a recent review.
iio_push_to_buffers_with_timestamp assumes the buffer used is aligned
to the size of the timestamp (8 bytes). This is not guaranteed in
this driver which uses an array of smaller elements on the stack.
As Lars also noted this anti pattern can involve a leak of data to
userspace and that indeed can happen here. We close both issues by
moving to a suitable structure in the iio_priv() data.
This data is allocated with kzalloc so no data can leak
apart from previous readings.
Explicit alignment of ts needed to ensure consistent padding
on all architectures (particularly x86_32 with it's 4 byte alignment
of s64)
Fixes: e4a70e3e7d84 ("iio: humidity: add support to hts221 rh/temp combo device")

[PATCH 4/4] staging: comedi: addi_apci_1500: check INSN_CONFIG_DIGITAL_TRIG shift
by Ian Abbott
The `INSN_CONFIG` comedi instruction with sub-instruction code
`INSN_CONFIG_DIGITAL_TRIG` includes a base channel in `data[3]`. This is
used as a right shift amount for other bitmask values without being
checked. Shift amounts greater than or equal to 32 will result in
undefined behavior. Add code to deal with this, adjusting the checks
for invalid channels so that enabled channel bits that would have been

[PATCH 3/4] staging: comedi: addi_apci_1564: check INSN_CONFIG_DIGITAL_TRIG shift
by Ian Abbott
The `INSN_CONFIG` comedi instruction with sub-instruction code
`INSN_CONFIG_DIGITAL_TRIG` includes a base channel in `data[3]`. This is
used as a right shift amount for other bitmask values without being
checked. Shift amounts greater than or equal to 32 will result in
undefined behavior. Add code to deal with this.

[PATCH 1/4] staging: comedi: ni_6527: fix INSN_CONFIG_DIGITAL_TRIG support
by Ian Abbott
`ni6527_intr_insn_config()` processes `INSN_CONFIG` comedi instructions
for the "interrupt" subdevice. When `data[0]` is
`INSN_CONFIG_DIGITAL_TRIG` it is configuring the digital trigger. When
`data[2]` is `COMEDI_DIGITAL_TRIG_ENABLE_EDGES` it is configuring rising
and falling edge detection for the digital trigger, using a base channel
number (or shift amount) in `data[3]`, a rising edge bitmask in
`data[4]` and falling edge bitmask in `data[5]`.
If the base channel number (shift amount) is greater than or equal to
the number of channels (24) of the digital input subdevice, there are no
changes to the rising and falling edges, so the mask of channels to be
changed can be set to 0, otherwise the mask of channels to be changed,
and the rising and falling edge bitmasks are shifted by the base channel
number before calling `ni6527_set_edge_detection()` to change the
appropriate registers. Unfortunately, the code is comparing the base
channel (shift amount) to the interrupt subdevice's number of channels
(1) instead of the digital input subdevice's number of channels (24).
Fix it by comparing to 32 because all shift amounts for an `unsigned
int` must be less than that and everything from bit 24 upwards is
ignored by `ni6527_set_edge_detection()` anyway.

Aborted tests
-------------
Tests that didn't complete running successfully are marked with ⚡⚡⚡.
If this was caused by an infrastructure issue, we try to mark that
explicitly in the report.
Waived tests
------------
If the test run included waived tests, they are marked with 🚧. Such tests are
executed but their results are not taken into account. Tests are waived when
their results are not reliable enough, e.g. when they're just introduced or are
being fixed.
Testing timeout
---------------
We aim to provide a report within reasonable timeframe. Tests that haven't
finished running yet are marked with ⏱.

[PATCH v3] sched/fair: handle case of task_h_load() returning 0
by Vincent Guittot
task_h_load() can return 0 in some situations like running stress-ng
mmapfork, which forks thousands of threads, in a sched group on a 224 cores
system. The load balance doesn't handle this correctly because
env->imbalance never decreases and it will stop pulling tasks only after
reaching loop_max, which can be equal to the number of running tasks of
the cfs. Make sure that imbalance will be decreased by at least 1.
misfit task is the other feature that doesn't handle correctly such
situation although it's probably more difficult to face the problem
because of the smaller number of CPUs and running tasks on heterogenous
system.
We can't simply ensure that task_h_load() returns at least one because it
would imply to handle underflow in other places.

[Stable-5.4][PATCH 0/3] arm64: Allow the compat vdso to be disabled at runtime
by Marc Zyngier
This is a backport of the series that recently went into 5.8. Note
that the first patch is more a complete rewriting than a backport, as
the vdso implementation in 5.4 doesn't have much in common with
mainline. This affects the 32bit arch code in a benign way.
It has seen very little testing, as I don't have the HW that triggers
this issue. I have run it in VMs by faking the CPU MIDR, and nothing
caught fire. Famous last words.
The original cover letter follows.
M.
The relatively recent introduction of the compat vdso on arm64 has
overlooked its interactions with some of the interesting errata
workarounds, such as ARM64_ERRATUM_1418040 (and its older 1188873
incarnation).
This erratum requires the 64bit kernel to trap 32bit accesses to the
virtual counter and emulate it. When the workaround was introduced,
the compat vdso simply wasn't a thing. Now that the patches have
landed in mainline, we trap the CVTVCT accesses from the vdso.
This can end-up in a nasty loop in the vdso, where the sequence number
changes on each trap, never stabilising, and leaving userspace in a
bit of a funny state (which is why we disable the vdso in most similar
cases). This erratum mentionned above is a bit special in the sense
that in only requires to trap AArch32 accesses, and 64bit tasks can be
left alone. Consequently, the vdso is never disabled and AArch32 tasks
are affected.
Obviously, we really want to retain the 64bit vdso in this case. To
that effect, this series offers a way to disable the 32bit view of the
vdso without impacting its 64bit counterpart, by providing a
"no-compat" vdso clock_mode, and plugging this feature into the
1418040 detection code.
Marc Zyngier (3):
arm64: Introduce a way to disable the 32bit vdso
arm64: arch_timer: Allow an workaround descriptor to disable compat
vdso
arm64: arch_timer: Disable the compat vdso for cores affected by

[PATCH 1/4] mm/page_alloc: fix non cma alloc context
by js1304＠gmail.com
From: Joonsoo Kim <iamjoonsoo.kim(a)lge.com>
Currently, preventing cma area in page allocation is implemented by using
current_gfp_context(). However, there are two problems of this
implementation.
First, this doesn't work for allocation fastpath. In the fastpath,
original gfp_mask is used since current_gfp_context() is introduced in
order to control reclaim and it is on slowpath.
Second, clearing __GFP_MOVABLE has a side effect to exclude the memory
on the ZONE_MOVABLE for allocation target.
To fix these problems, this patch changes the implementation to exclude
cma area in page allocation. Main point of this change is using the
alloc_flags. alloc_flags is mainly used to control allocation so it fits
for excluding cma area in allocation.
Fixes: d7fefcc (mm/cma: add PF flag to force non cma alloc)

From: Muchun Song <songmuchun(a)bytedance.com>
Subject: mm: memcg/slab: fix memory leak at non-root kmem_cache destroy
If the kmem_cache refcount is greater than one, we should not mark the
root kmem_cache as dying. If we mark the root kmem_cache dying
incorrectly, the non-root kmem_cache can never be destroyed. It resulted
in memory leak when memcg was destroyed. We can use the following steps
to reproduce.
1) Use kmem_cache_create() to create a new kmem_cache named A.
2) Coincidentally, the kmem_cache A is an alias for kmem_cache B,
so the refcount of B is just increased.
3) Use kmem_cache_destroy() to destroy the kmem_cache A, just
decrease the B's refcount but mark the B as dying.
4) Create a new memory cgroup and alloc memory from the kmem_cache
B. It leads to create a non-root kmem_cache for allocating memory.
5) When destroy the memory cgroup created in the step 4), the
non-root kmem_cache can never be destroyed.
If we repeat steps 4) and 5), this will cause a lot of memory leak. So
only when refcount reach zero, we mark the root kmem_cache as dying.

[PATCH] RISC-V: Upgrade smp_mb__after_spinlock() to iorw,iorw
by Palmer Dabbelt
While digging through the recent mmiowb preemption issue it came up that
we aren't actually preventing IO from crossing a scheduling boundary.
While it's a bit ugly to overload smp_mb__after_spinlock() with this
behavior, it's what PowerPC is doing so there's some precedent.

[PATCH v2 1/2] drm/panel-simple: Fix inverted V/H SYNC for Frida FRD350H54004 panel
by Paul Cercueil
The FRD350H54004 panel was marked as having active-high VSYNC and HSYNC
signals, which sorts-of worked, but resulted in the picture fading out
under certain circumstances.
Fix this issue by marking VSYNC and HSYNC signals active-low.
v2: Rebase on drm-misc-next
Fixes: 7b6bd8433609 ("drm/panel: simple: Add support for the Frida FRD350H54004 panel")

Aborted tests
-------------
Tests that didn't complete running successfully are marked with ⚡⚡⚡.
If this was caused by an infrastructure issue, we try to mark that
explicitly in the report.
Waived tests
------------
If the test run included waived tests, they are marked with 🚧. Such tests are
executed but their results are not taken into account. Tests are waived when
their results are not reliable enough, e.g. when they're just introduced or are
being fixed.
Testing timeout
---------------
We aim to provide a report within reasonable timeframe. Tests that haven't
finished running yet are marked with ⏱.

patch "USB: serial: iuu_phoenix: fix memory corruption" added to usb-linus
by gregkh＠linuxfoundation.org
This is a note to let you know that I've just added the patch titled
USB: serial: iuu_phoenix: fix memory corruption
to my usb git tree which can be found at
git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb.git
in the usb-linus branch.
The patch will show up in the next release of the linux-next tree
(usually sometime within the next 24 hours during the week.)
The patch will hopefully also be merged in Linus's tree for the
next -rc kernel release.
If you have any questions about this process, please let me know.
>From e7b931bee739e8a77ae216e613d3b99342b6dec0 Mon Sep 17 00:00:00 2001
From: Johan Hovold <johan(a)kernel.org>
Date: Wed, 15 Jul 2020 11:02:45 +0200
Subject: USB: serial: iuu_phoenix: fix memory corruption
The driver would happily overwrite its write buffer with user data in
256 byte increments due to a removed buffer-space sanity check.
Fixes: 5fcf62b0f1f2 ("tty: iuu_phoenix: fix locking.")
Cc: stable <stable(a)vger.kernel.org> # 2.6.31

[PATCH v2 5/6] drm/ast: Initialize DRAM type before posting GPU
by Thomas Zimmermann
Posting the GPU requires the correct DRAM type to be stored in
struct ast_private. Therefore first initialize the DRAM info and
then post the GPU. This restores the original order of instructions
in this function.

[PATCH v2 for 5.4 1/2] crypto: atmel - Fix selection of CRYPTO_AUTHENC
by Tudor Ambarus
Backport to 5.4.52-rc1:
commit d158367682cd822aca811971e988be6a8d8f679f upstream.
The following error is raised when CONFIG_CRYPTO_DEV_ATMEL_AES=y and
CONFIG_CRYPTO_DEV_ATMEL_AUTHENC=m:
drivers/crypto/atmel-aes.o: In function `atmel_aes_authenc_setkey':
atmel-aes.c:(.text+0x9bc): undefined reference to `crypto_authenc_extractkeys'
Makefile:1094: recipe for target 'vmlinux' failed
Fix it by moving the selection of CRYPTO_AUTHENC under
config CRYPTO_DEV_ATMEL_AES.
Fixes: 89a82ef87e01 ("crypto: atmel-authenc - add support to...")

[PATCH] drm/i915: Provide the perf pmu.module
by Chris Wilson
Rather than manually implement our own module reference counting for perf

pmu for this very purpose.

[PATCH v2] sched/fair: handle case of task_h_load() returning 0
by Vincent Guittot
task_h_load() can return 0 in some situations like running stress-ng
mmapfork, which forks thousands of threads, in a sched group on a 224 cores
system. The load balance doesn't handle this correctly because
env->imbalance never decreases and it will stop pulling tasks only after
reaching loop_max, which can be equal to the number of running tasks of
the cfs. Make sure that imbalance will be decreased by at least 1.
misfit task is the other feature that doesn't handle correctly such
situation although it's probably more difficult to face the problem
because of the smaller number of CPUs and running tasks on heterogenous
system.
We can't simply ensure that task_h_load() returns at least one because it
would imply to handle underflow in other places.

[PATCH v3 2/7] arm64: ptrace: Override SPSR.SS when single-stepping is enabled
by Will Deacon
Luis reports that, when reverse debugging with GDB, single-step does not
function as expected on arm64:
| I've noticed, under very specific conditions, that a PTRACE_SINGLESTEP
| request by GDB won't execute the underlying instruction. As a consequence,
| the PC doesn't move, but we return a SIGTRAP just like we would for a
| regular successful PTRACE_SINGLESTEP request.
The underlying problem is that when the CPU register state is restored
as part of a reverse step, the SPSR.SS bit is cleared and so the hardware
single-step state can transition to the "active-pending" state, causing
an unexpected step exception to be taken immediately if a step operation
is attempted.
In hindsight, we probably shouldn't have exposed SPSR.SS in the pstate
accessible by the GPR regset, but it's a bit late for that now. Instead,
simply prevent userspace from configuring the bit to a value which is
inconsistent with the TIF_SINGLESTEP state for the task being traced.

timer: Prevent base->clk from moving backward
When a timer is enqueued with a negative delta (ie: expiry is below
base->clk), it gets added to the wheel as expiring now (base->clk).
Yet the value that gets stored in base->next_expiry, while calling
trigger_dyntick_cpu(), is the initial timer->expires value. The
resulting state becomes:
base->next_expiry < base->clk
On the next timer enqueue, forward_timer_base() may accidentally
rewind base->clk. As a possible outcome, timers may expire way too
early, the worst case being that the highest wheel levels get spuriously
processed again.
To prevent from that, make sure that base->next_expiry doesn't get below
base->clk.

[PATCH] vhost/scsi: fix up req type endian-ness
by Michael S. Tsirkin
vhost/scsi doesn't handle type conversion correctly

[PATCH 1/2] nvme-tpc: don't use sendpage for pages not taking reference counter
by Coly Li
Currently nvme_tcp_try_send_data() doesn't use kernel_sendpage() to
send slab pages. But for pages allocated by __get_free_pages() without
__GFP_COMP, which also have refcount as 0, they are still sent by
kernel_sendpage() to remote end, this is problematic.
When bcache uses a remote NVMe SSD via nvme-over-tcp as its cache
device, writing meta data e.g. cache_set->disk_buckets to remote SSD may
trigger a kernel panic due to the above problem. Bcause the meta data
pages for cache_set->disk_buckets are allocated by __get_free_pages()
without __GFP_COMP.
This problem should be fixed both in upper layer driver (bcache) and
nvme-over-tcp code. This patch fixes the nvme-over-tcp code by checking
whether the page refcount is 0, if yes then don't use kernel_sendpage()
and call sock_no_sendpage() to send the page into network stack.
The code comments in this patch is copied and modified from drbd where
the similar problem already gets solved by Philipp Reisner. This is the
best code comment including my own version.

[PATCH v3 1/7] arm64: ptrace: Consistently use pseudo-singlestep exceptions
by Will Deacon
Although the arm64 single-step state machine can be fast-forwarded in
cases where we wish to generate a SIGTRAP without actually executing an
instruction, this has two major limitations outside of simply skipping
an instruction due to emulation.
1. Stepping out of a ptrace signal stop into a signal handler where
SIGTRAP is blocked. Fast-forwarding the stepping state machine in
this case will result in a forced SIGTRAP, with the handler reset to
SIG_DFL.
2. The hardware implicitly fast-forwards the state machine when executing
an SVC instruction for issuing a system call. This can interact badly
with subsequent ptrace stops signalled during the execution of the
system call (e.g. SYSCALL_EXIT or seccomp traps), as they may corrupt
the stepping state by updating the PSTATE for the tracee.
Resolve both of these issues by injecting a pseudo-singlestep exception
on entry to a signal handler and also on return to userspace following a
system call.

[PATCH 04/10] drm/amd/display: OLED panel backlight adjust not work with external display connected

From: hersen wu <hersenxs.wu(a)amd.com>
[Why]
amdgpu_dm->backlight_caps is for single eDP only. the caps are upddated
for very connector. Real eDP caps will be overwritten by other external
display. For OLED panel, caps->aux_support is set to 1 for OLED pnael.
after external connected, caps+.aux_support is set to 0. This causes
OLED backlight adjustment not work.
[How]
within update_conector_ext_caps, backlight caps will be updated only for
eDP connector.

[PATCH] hid-input: Fix devices that return multiple bytes in battery report
by Grant Likely
Some devices, particularly the 3DConnexion Spacemouse wireless 3D
controllers, return more than just the battery capacity in the battery
report. The Spacemouse devices return an additional byte with a device
specific field. However, hidinput_query_battery_capacity() only
requests a 2 byte transfer.
When a spacemouse is connected via USB (direct wire, no wireless dongle)
and it returns a 3 byte report instead of the assumed 2 byte battery
report the larger transfer confuses and frightens the USB subsystem
which chooses to ignore the transfer. Then after 2 seconds assume the
device has stopped responding and reset it. This can be reproduced
easily by using a wired connection with a wireless spacemouse. The
Spacemouse will enter a loop of resetting every 2 seconds which can be
observed in dmesg.
This patch solves the problem by increasing the transfer request to 4
bytes instead of 2. The fix isn't particularly elegant, but it is simple
and safe to backport to stable kernels. A further patch will follow to
more elegantly handle battery reports that contain additional data.

[PATCH v3 3/7] arm64: compat: Ensure upper 32 bits of x0 are zero on syscall return
by Will Deacon
Although we zero the upper bits of x0 on entry to the kernel from an
AArch32 task, we do not clear them on the exception return path and can
therefore expose 64-bit sign extended syscall return values to userspace
via interfaces such as the 'perf_regs' ABI, which deal exclusively with
64-bit registers.
Explicitly clear the upper 32 bits of x0 on return from a compat system
call.

[PATCH] timer: Fix wheel index calculation on last level
by Frederic Weisbecker
When an expiration delta falls into the last level of the wheel, we want
to compare that delta against the maximum possible delay and reduce our
delta to fit in if necessary.
However instead of comparing the delta against the maximum, we are
comparing the actual expiry against the maximum. Then instead of fixing
the delta to fit in, we set the maximum delta as the expiry value.
This can result in various undesired outcomes, the worst possible one
being a timer expiring 15 days ahead to fire immediately.
Fixes: 500462a9de65 ("timers: Switch to a non-cascading wheel")

[PATCH] megaraid_sas: remove undefined ENABLE_IRQ_POLL macro
by Chandrakanth Patil
Issue:
As ENABLE_IRQ_POLL macro is undefined, the check for ENABLE_IRQ_POLL
macro in ISR will always be false leads to irq polling non-functional.
Fix:
Remove ENABLE_IRQ_POLL check from isr
Fixes: a6ffd5bf6819 ("scsi: megaraid_sas: Call disable_irq from process IRQ")

[PATCH] serial: 8250_mtk: Fix high-speed baud rates clamping
by Serge Semin
Commit 7b668c064ec3 ("serial: 8250: Fix max baud limit in generic 8250
port") fixed limits of a baud rate setting for a generic 8250 port.
In other words since that commit the baud rate has been permitted to be
within [uartclk / 16 / UART_DIV_MAX; uartclk / 16], which is absolutely
normal for a standard 8250 UART port. But there are custom 8250 ports,
which provide extended baud rate limits. In particular the Mediatek 8250
port can work with baud rates up to "uartclk" speed.
Normally that and any other peculiarity is supposed to be handled in a
custom set_termios() callback implemented in the vendor-specific
8250-port glue-driver. Currently that is how it's done for the most of
the vendor-specific 8250 ports, but for some reason for Mediatek a
solution has been spread out to both the glue-driver and to the generic
8250-port code. Due to that a bug has been introduced, which permitted the
extended baud rate limit for all even for standard 8250-ports. The bug
has been fixed by the commit 7b668c064ec3 ("serial: 8250: Fix max baud
limit in generic 8250 port") by narrowing the baud rates limit back down to
the normal bounds. Unfortunately by doing so we also broke the
Mediatek-specific extended bauds feature.
A fix of the problem described above is twofold. First since we can't get
back the extended baud rate limits feature to the generic set_termios()
function and that method supports only a standard baud rates range, the
requested baud rate must be locally stored before calling it and then
restored back to the new termios structure after the generic set_termios()
finished its magic business. By doing so we still use the
serial8250_do_set_termios() method to set the LCR/MCR/FCR/etc. registers,
while the extended baud rate setting procedure will be performed later in
the custom Mediatek-specific set_termios() callback. Second since a true
baud rate is now fully calculated in the custom set_termios() method we
need to locally update the port timeout by calling the
uart_update_timeout() function. After the fixes described above are
implemented in the 8250_mtk.c driver, the Mediatek 8250-port should
get back to normally working with extended baud rates.

Folks, sorry for a delay with the problem fix. A solution is turned out to
be a bit more complicated than I originally thought in my comment to the
Daniel revert-patch.
Please also note, that I don't have a Mediatek hardware to test the
solution suggested in the patch. The code is written as on so called
the tip of the pen after digging into the 8250_mtk.c and 8250_port.c
drivers code. So please Daniel or someone with Mediatek 8250-port
available on a board test this patch first and report about the results in
reply to this emailing thread. After that, if your conclusion is positive
and there is no objection against the solution design the patch can be
merged in.

Aborted tests
-------------
Tests that didn't complete running successfully are marked with ⚡⚡⚡.
If this was caused by an infrastructure issue, we try to mark that
explicitly in the report.
Waived tests
------------
If the test run included waived tests, they are marked with 🚧. Such tests are
executed but their results are not taken into account. Tests are waived when
their results are not reliable enough, e.g. when they're just introduced or are
being fixed.
Testing timeout
---------------
We aim to provide a report within reasonable timeframe. Tests that haven't
finished running yet are marked with ⏱.

[PATCH] media: cedrus: Propagate OUTPUT resolution to CAPTURE
by Nicolas Dufresne
As per spec, the CAPTURE resolution should be automatically set based on
the OTUPUT resolution. This patch properly propagate width/height to the
capture when the OUTPUT format is set and override the user provided
width/height with configured OUTPUT resolution when the CAPTURE fmt is
updated.
This also prevents userspace from selecting a CAPTURE resolution that is
too small, avoiding unwanted page faults.

[PATCH] fs/9p: Fix TCREATE's fid in protocol
by Victor Hsieh
The fid parameter of TCREATE represents the directory that the file
should be created at. The current implementation mistakenly passes a
locally created fid for the file. The correct file fid is usually
retrieved by another WALK call, which does happen right after.
The problem happens when a new created fd is read from (i.e. where
private_data->fid is used), but not write to.
Fixes: 5643135a2846 ("fs/9p: This patch implements TLCREATE for 9p2000.L protocol.")

[PATCH 5.4] crypto: atmel - Fix build error of CRYPTO_AUTHENC
by Tudor Ambarus
Backport to 5.4.52-rc1 the following commits in upstream:
commit aee1f9f3c30e1e20e7f74729ced61eac7d74ca68 upstream.
commit d158367682cd822aca811971e988be6a8d8f679f upstream.
If CRYPTO_DEV_ATMEL_AUTHENC is m, CRYPTO_DEV_ATMEL_SHA is m,
but CRYPTO_DEV_ATMEL_AES is y, building will fail:
drivers/crypto/atmel-aes.o: In function `atmel_aes_authenc_init_tfm':

drivers/crypto/atmel-aes.o: In function `atmel_aes_authenc_setkey':

Make CRYPTO_DEV_ATMEL_AUTHENC depend on CRYPTO_DEV_ATMEL_AES,
and select CRYPTO_DEV_ATMEL_SHA and CRYPTO_AUTHENC for it under there.

[PATCH 38/66] drm/i915/gt: Use virtual_engine during execlists_dequeue
by Chris Wilson
Rather than going back and forth between the rb_node entry and the
virtual_engine type, store the ve local and reuse it. As the
container_of conversion from rb_node to virtual_engine requires a
variable offset, performing that conversion just once shaves off a bit
of code.
v2: Keep a single virtual engine lookup, for typical use.

[PATCH 1/2] dma-buf/sw_sync: Avoid recursive lock during fence signal
by Chris Wilson
If a signal callback releases the sw_sync fence, that will trigger a
deadlock as the timeline_fence_release recurses onto the fence->lock
(used both for signaling and the the timeline tree).
If we always hold a reference for an unsignaled fence held by the
timeline, we no longer need to detach the fence from the timeline upon
release. This is only possible since commit ea4d5a270b57
("dma-buf/sw_sync: force signal all unsignaled fences on dying timeline")
where we introduced decoupling of the fences from the timeline upon release.

commit 4b661d6133c5d3a7c9aca0b4ee5a78c7766eff3f upstream.
ARM64_WORKAROUND_1418040 requires that AArch32 EL0 accesses to
the virtual counter register are trapped and emulated by the kernel.
This makes the vdso pretty pointless, and in some cases livelock
prone.
Provide a workaround entry that limits the vdso to 64bit tasks.

[PATCH] virtio_balloon: clear modern features under legacy
by Michael S. Tsirkin
Page reporting features were never supported by legacy hypervisors.
Supporting them poses a problem: should we use native endian-ness (like
current code assumes)? Or little endian-ness like the virtio spec says?
Rather than try to figure out, and since results of
incorrect endian-ness are dire, let's just block this configuration.

[PATCH 1/3] dma-buf/sw_sync: Avoid recursive lock during fence signal.
by Chris Wilson
From: Bas Nieuwenhuizen <bas(a)basnieuwenhuizen.nl>
Calltree:
timeline_fence_release
drm_sched_entity_wakeup
dma_fence_signal_locked
sync_timeline_signal
sw_sync_ioctl
Releasing the reference to the fence in the fence signal callback
seems reasonable to me, so this patch avoids the locking issue in
sw_sync.
d3862e44daa7 ("dma-buf/sw-sync: Fix locking around sync_timeline lists")
fixed the recursive locking issue but caused an use-after-free. Later
d3c6dd1fb30d ("dma-buf/sw_sync: Synchronize signal vs syncpt free")
fixed the use-after-free but reintroduced the recursive locking issue.
In this attempt we avoid the use-after-free still because the release
function still always locks, and outside of the locking region in the
signal function we have properly refcounted references.
We furthermore also avoid the recurive lock by making sure that either:
1) We have a properly refcounted reference, preventing the signal from
triggering the release function inside the locked region.
2) The refcount was already zero, and hence nobody will be able to trigger
the release function from the signal function.
v2: Move dma_fence_signal() into second loop in preparation to moving
the callback out of the timeline obj->lock.

[PATCH] RISC-V: Double the stack size on rv64
by Palmer Dabbelt
This was suggested in the syzkaller thread as a fix for a bunch of issues. It
seems in line with what other architectures are doing, and while I haven't
personally figured out how to reproduce the issues they seem believable enough
to just change it.
Fixes: 7db91e57a0ac ("RISC-V: Task implementation")
Cc: stable(a)vger.kernel.org
Signed-off-by: Palmer Dabbelt <palmerdabbelt(a)google.com>

I've put this on fixes as I don't see a patch from anyone on that thread, and
it seems straight-forward enough to just do it. If there's any issues I'm
happy to listen, otherwise this is going up later this week.

[PATCH v2 1/3] dma-buf/sw_sync: Avoid recursive lock during fence signal.
by Chris Wilson
From: Bas Nieuwenhuizen <bas(a)basnieuwenhuizen.nl>
Calltree:
timeline_fence_release
drm_sched_entity_wakeup
dma_fence_signal_locked
sync_timeline_signal
sw_sync_ioctl
Releasing the reference to the fence in the fence signal callback
seems reasonable to me, so this patch avoids the locking issue in
sw_sync.
d3862e44daa7 ("dma-buf/sw-sync: Fix locking around sync_timeline lists")
fixed the recursive locking issue but caused an use-after-free. Later
d3c6dd1fb30d ("dma-buf/sw_sync: Synchronize signal vs syncpt free")
fixed the use-after-free but reintroduced the recursive locking issue.
In this attempt we avoid the use-after-free still because the release
function still always locks, and outside of the locking region in the
signal function we have properly refcounted references.
We furthermore also avoid the recurive lock by making sure that either:
1) We have a properly refcounted reference, preventing the signal from
triggering the release function inside the locked region.
2) The refcount was already zero, and hence nobody will be able to trigger
the release function from the signal function.
v2: Move dma_fence_signal() into second loop in preparation to moving
the callback out of the timeline obj->lock.
Fixes: d3c6dd1fb30d ("dma-buf/sw_sync: Synchronize signal vs syncpt free")

Question is what the scope should be. Using this method we only take a
reference and avoid releasing the fences we're going to signal.
However the lock is on the timeline and dma_fence_signal already takes
the lock, so if the signal ends up releasing any of the other fences
in the timeline (e.g. the fences that are later than the new value),
then we are still going to have the recursive locking issue.
One solution to that would be splitting the lock into 2 locks: 1
protecting pt_list + pt_tree and 1 protecting value & serving as the
lock for the fences. Then we can only take the list lock in the
release function and dma_fence_signal takes the value lock. However,
then you still have issues like if a callback for fence A (when called
it holds the lock of A's timeline) adds a callback to fence B of the
same timeline (requires the fence lock) we still have a recursion
locking issue.
I'm not sure it is reasonable for the last use case to work, because I
only see it working with per-fence locks, but per-fence locks are
deadlock prone due to the order of taking links not really being
fixed.

[PATCH] [stable v5.4.x] pwm: jz4740: Fix build failure
by Uwe Kleine-König
When commit 9017dc4fbd59 ("pwm: jz4740: Enhance precision in calculation
of duty cycle") from v5.8-rc1 was backported to v5.4.x its dependency on
commit ce1f9cece057 ("pwm: jz4740: Use clocks from TCU driver") was not
noticed which made the pwm-jz4740 driver fail to build.
As ce1f9cece057 depends on still more rework, just backport a small part
of this commit to make the driver build again. (There is no dependency
on the functionality introduced in ce1f9cece057, just the rate variable
is needed.)

Hello,
@Paul: Can you please check this is correct? I only build-tested this
change.

[PATCH 1/2] serial: tegra: fix CREAD handling for PIO
by Johan Hovold
Commit 33ae787b74fc ("serial: tegra: add support to ignore read") added
support for dropping input in case CREAD isn't set, but for PIO the
ignore_status_mask wasn't checked until after the character had been
put in the receive buffer.
Note that the NULL tty-port test is bogus and will be removed by a
follow-on patch.

irqdomain/treewide: Keep firmware node unconditionally allocated
Quite some non OF/ACPI users of irqdomains allocate firmware nodes of type
IRQCHIP_FWNODE_NAMED or IRQCHIP_FWNODE_NAMED_ID and free them right after
creating the irqdomain. The only purpose of these FW nodes is to convey
name information. When this was introduced the core code did not store the
pointer to the node in the irqdomain. A recent change stored the firmware
node pointer in irqdomain for other reasons and missed to notice that the
usage sites which do the alloc_fwnode/create_domain/free_fwnode sequence
are broken by this. Storing a dangling pointer is dangerous itself, but in
case that the domain is destroyed later on this leads to a double free.
Remove the freeing of the firmware node after creating the irqdomain from
all affected call sites to cure this.
Fixes: 711419e504eb ("irqdomain: Add the missing assignment of domain->fwnode for named fwnode")

[PATCH] dma-buf/sw_sync: Avoid recursive lock during fence signal.
by Bas Nieuwenhuizen
Calltree:
timeline_fence_release
drm_sched_entity_wakeup
dma_fence_signal_locked
sync_timeline_signal
sw_sync_ioctl
Releasing the reference to the fence in the fence signal callback
seems reasonable to me, so this patch avoids the locking issue in
sw_sync.
d3862e44daa7 ("dma-buf/sw-sync: Fix locking around sync_timeline lists")
fixed the recursive locking issue but caused an use-after-free. Later
d3c6dd1fb30d ("dma-buf/sw_sync: Synchronize signal vs syncpt free")
fixed the use-after-free but reintroduced the recursive locking issue.
In this attempt we avoid the use-after-free still because the release
function still always locks, and outside of the locking region in the
signal function we have properly refcounted references.
We furthermore also avoid the recurive lock by making sure that either:
1) We have a properly refcounted reference, preventing the signal from
triggering the release function inside the locked region.
2) The refcount was already zero, and hence nobody will be able to trigger
the release function from the signal function.

[PATCH AUTOSEL 4.9 01/10] pinctrl: amd: fix npins for uart0 in kerncz_groups
by Sasha Levin
From: Jacky Hu <hengqing.hu(a)gmail.com>
[ Upstream commit 69339d083dfb7786b0e0b3fc19eaddcf11fabdfb ]
uart0_pins is defined as:
static const unsigned uart0_pins[] = {135, 136, 137, 138, 139};
which npins is wronly specified as 9 later
{
.name = "uart0",
.pins = uart0_pins,
.npins = 9,
},
npins should be 5 instead of 9 according to the definition.

perf: util/syscalltbl.c:43:38: error: ‘SYSCALLTBL_ARM64_MAX_ID’ undeclared here (not in a function)
by Gordan Bobic
I hit this FTBFS earlier today while trying to build the LT 4.19.132
kernel from source:
https://lore.kernel.org/patchwork/patch/960281/
The "quick hack" patch mentioned at the bottom of the thread gets it
to compile. Is this the correct solution, or is there a better fix? As
it stands, tools/perf doesn't seem to compile on 4.19.132.

Subject: [PATCH] drm/nouveau/nouveau: fix page fault on device private memory
If system memory is migrated to device private memory and no GPU MMU
page table entry exists, the GPU will fault and call hmm_range_fault()
to get the PFN for the page. Since the .dev_private_owner pointer in
struct hmm_range is not set, hmm_range_fault returns an error which
results in the GPU program stopping with a fatal fault.
Fix this by setting .dev_private_owner appropriately.

Subject: [PATCH] dm: do not use waitqueue for request-based DM
Given request-based DM now uses blk-mq's blk_mq_queue_inflight() to
determine if outstanding IO has completed (and DM has no control over
the blk-mq state machine used to track outstanding IO) it is unsafe to
wakeup waiter (dm_wait_for_completion) before blk-mq has cleared a
request's state bits (e.g. MQ_RQ_IN_FLIGHT or MQ_RQ_COMPLETE). As
such dm_wait_for_completion() could be left to wait indefinitely if no
other requests complete.
Fix this by eliminating request-based DM's use of waitqueue to wait
for blk-mq requests to complete in dm_wait_for_completion.

Subject: [PATCH] pinctrl: baytrail: Fix pin being driven low for a while on
gpiod_get(..., GPIOD_OUT_HIGH)
The pins on the Bay Trail SoC have separate input-buffer and output-buffer
enable bits and a read of the level bit of the value register will always
return the value from the input-buffer.
The BIOS of a device may configure a pin in output-only mode, only enabling
the output buffer, and write 1 to the level bit to drive the pin high.
This 1 written to the level bit will be stored inside the data-latch of the
output buffer.
But a subsequent read of the value register will return 0 for the level bit
because the input-buffer is disabled. This causes a read-modify-write as
done by byt_gpio_set_direction() to write 0 to the level bit, driving the
pin low!
Before this commit byt_gpio_direction_output() relied on
pinctrl_gpio_direction_output() to set the direction, followed by a call
to byt_gpio_set() to apply the selected value. This causes the pin to
go low between the pinctrl_gpio_direction_output() and byt_gpio_set()
calls.
Change byt_gpio_direction_output() to directly make the register
modifications itself instead. Replacing the 2 subsequent writes to the
value register with a single write.
Note that the pinctrl code does not keep track internally of the direction,
so not going through pinctrl_gpio_direction_output() is not an issue.
This issue was noticed on a Trekstor SurfTab Twin 10.1. When the panel is
already on at boot (no external monitor connected), then the i915 driver
does a gpiod_get(..., GPIOD_OUT_HIGH) for the panel-enable GPIO. The
temporarily going low of that GPIO was causing the panel to reset itself
after which it would not show an image until it was turned off and back on
again (until a full modeset was done on it). This commit fixes this.
This commit also updates the byt_gpio_direction_input() to use direct
register accesses instead of going through pinctrl_gpio_direction_input(),
to keep it consistent with byt_gpio_direction_output().
Note for backporting, this commit depends on:

gpiod_get(..., GPIOD_OUT_HIGH)
The pins on the Bay Trail SoC have separate input-buffer and output-buffer

The BIOS of a device may configure a pin in output-only mode, only enabling

This 1 written to the level bit will be stored inside the data-latch of the

But a subsequent read of the value register will return 0 for the level bit
because the input-buffer is disabled. This causes a read-modify-write as
done by byt_gpio_set_direction() to write 0 to the level bit, driving the
pin low!

to byt_gpio_set() to apply the selected value. This causes the pin to
go low between the pinctrl_gpio_direction_output() and byt_gpio_set()

Change byt_gpio_direction_output() to directly make the register
modifications itself instead. Replacing the 2 subsequent writes to the
value register with a single write.
Note that the pinctrl code does not keep track internally of the direction,
so not going through pinctrl_gpio_direction_output() is not an issue.

Subject: [PATCH] pinctrl: baytrail: Fix pin being driven low for a while on
gpiod_get(..., GPIOD_OUT_HIGH)
The pins on the Bay Trail SoC have separate input-buffer and output-buffer
enable bits and a read of the level bit of the value register will always
return the value from the input-buffer.
The BIOS of a device may configure a pin in output-only mode, only enabling
the output buffer, and write 1 to the level bit to drive the pin high.
This 1 written to the level bit will be stored inside the data-latch of the
output buffer.
But a subsequent read of the value register will return 0 for the level bit
because the input-buffer is disabled. This causes a read-modify-write as
done by byt_gpio_set_direction() to write 0 to the level bit, driving the
pin low!
Before this commit byt_gpio_direction_output() relied on
pinctrl_gpio_direction_output() to set the direction, followed by a call
to byt_gpio_set() to apply the selected value. This causes the pin to
go low between the pinctrl_gpio_direction_output() and byt_gpio_set()
calls.
Change byt_gpio_direction_output() to directly make the register
modifications itself instead. Replacing the 2 subsequent writes to the
value register with a single write.
Note that the pinctrl code does not keep track internally of the direction,
so not going through pinctrl_gpio_direction_output() is not an issue.
This issue was noticed on a Trekstor SurfTab Twin 10.1. When the panel is
already on at boot (no external monitor connected), then the i915 driver
does a gpiod_get(..., GPIOD_OUT_HIGH) for the panel-enable GPIO. The
temporarily going low of that GPIO was causing the panel to reset itself
after which it would not show an image until it was turned off and back on
again (until a full modeset was done on it). This commit fixes this.
This commit also updates the byt_gpio_direction_input() to use direct
register accesses instead of going through pinctrl_gpio_direction_input(),
to keep it consistent with byt_gpio_direction_output().
Note for backporting, this commit depends on:
commit e2b74419e5cc ("pinctrl: baytrail: Replace WARN with dev_info_once
when setting direct-irq pin to output")

Please revert "ath9k: Fix general protection fault in ath9k_hif_usb_rx_cb" from all stable kernels
by Hans de Goede
Hi Greg (et all),
Note several people are already working on this, so you may already have a request for this.
The "ath9k: Fix general protection fault in ath9k_hif_usb_rx_cb" commit which has been
added to several stable kernels (at least to 5.4.y and 5.7.y, but likely also to others)
is breaking networking for people with an ath9k card.
A revert has been submitted upstream, but it does not seem to have found it way
upstream yet. It has been cherry-picked by the Arch people:
https://git.archlinux.org/linux.git/commit/?h=v5.7.8-arch1&id=1a32e7b57b0b3…
So if you want to credit some of the original people working on fixing this,
you can find the revert submitted upstream there.
Reverting this fixes / also see:
https://bugzilla.kernel.org/show_bug.cgi?id=208251
https://bugzilla.redhat.com/show_bug.cgi?id=1848631

Subject: [PATCH] KVM: arm64: Fix kvm_reset_vcpu() return code being incorrect
with SVE
If SVE is enabled then 'ret' can be assigned the return value of
kvm_vcpu_enable_sve() which may be 0 causing future "goto out" sites to
erroneously return 0 on failure rather than -EINVAL as expected.
Remove the initialisation of 'ret' and make setting the return value
explicit to avoid this situation in the future.

[PATCH] drm/vmwgfx: fix update of display surface when resolution changes
by Roland Scheidegger (VMware)
From: Roland Scheidegger <sroland(a)vmware.com>
The assignment of metadata overwrote the new display resolution values,
hence we'd miss the size actually changed and wouldn't redefine the
surface. This would then lead to command buffer error when trying to
update the screen target (due to the size mismatch), and result in a

[PATCH] drm/i915: Recalculate FBC w/a stride when needed
by Ville Syrjala
From: Ville Syrjälä <ville.syrjala(a)linux.intel.com>
Currently we're failing to recalculate the gen9 FBC w/a stride
unless something more drastic than just the modifier itself has
changed. This often leaves us with FBC enabled with the linear
fbdev framebuffer without the w/a stride enabled. That will cause
an immediate underrun and FBC will get promptly disabled.
Fix the problem by checking if the w/a stride is about to change,
and go through the full dance if so. This part of the FBC code
is still pretty much a disaster and will need lots more work.
But this should at least fix the immediate issue.

[PATCH] drm/i915/gt: Only swap to a random sibling once upon creation
by Chris Wilson
The danger in switching at random upon intel_context_pin is that the
context may still actually be inflight, as it will not be scheduled out
until a context switch after it is complete -- that is after we do a
final intel_context_unpin.

[PATCH] drm/i915: Skip signaling a signaled request
by Chris Wilson
Preempt-to-busy introduces various fascinating complications in that the
requests may complete as we are unsubmitting them from HW. As they may
then signal after unsubmission, we may find ourselves having to cleanup
the signaling request from within the signaling callback. This causes us
to recurse onto the same i915_request.lock.
However, if the request is already signaled (as it will be before we
enter the signal callbacks), we know we can skip the signaling of that
request during submission, neatly evading the spinlock recursion.
unsubmit(ve.rq0) # timeslice expiration or other preemption
-> virtual_submit_request(ve.rq0)
dma_fence_signal(ve.rq0) # request completed before preemption ack
-> submit_notify(ve.rq1)
-> virtual_submit_request(ve.rq1) # sees that we have completed ve.rq0
-> __i915_request_submit(ve.rq0)

Subject: [PATCH] KVM: x86: Mark CR4.TSD as being possibly owned by the guest
Mark CR4.TSD as being possibly owned by the guest as that is indeed the
case on VMX. Without TSD being tagged as possibly owned by the guest, a
targeted read of CR4 to get TSD could observe a stale value. This bug
is benign in the current code base as the sole consumer of TSD is the
emulator (for RDTSC) and the emulator always "reads" the entirety of CR4
when grabbing bits.
Add a build-time assertion in to ensure VMX doesn't hand over more CR4
bits without also updating x86.

Subject: [PATCH] KVM: arm64: Fix kvm_reset_vcpu() return code being incorrect
with SVE
If SVE is enabled then 'ret' can be assigned the return value of
kvm_vcpu_enable_sve() which may be 0 causing future "goto out" sites to
erroneously return 0 on failure rather than -EINVAL as expected.
Remove the initialisation of 'ret' and make setting the return value
explicit to avoid this situation in the future.

[PATCH] drm/bridge: sil_sii8620: initialize return of sii8620_readb
by trix＠redhat.com
From: Tom Rix <trix(a)redhat.com>
clang static analysis flags this error
sil-sii8620.c:184:2: warning: Undefined or garbage value
returned to caller [core.uninitialized.UndefReturn]
return ret;
^~~~~~~~~~
sii8620_readb calls sii8620_read_buf.
sii8620_read_buf can return without setting its output
pararmeter 'ret'.
So initialize ret.

Subject: [PATCH] ALSA: hda/realtek - Fix Lenovo Thinkpad X1 Carbon 7th quirk
subdevice id
1)
In snd_hda_pick_fixup(), quirks are first matched by PCI SSID and then, if
there is no match, by codec SSID. The Lenovo "ThinkPad X1 Carbon 7th" has
an audio chip with PCI SSID 0x2292 and codec SSID 0x2293[1]. Therefore, fix
the quirk meant for that device to match on .subdevice == 0x2292.
2)
The "Thinkpad X1 Yoga 7th" does not exist. The companion product to the
Carbon 7th is the Yoga 4th. That device has an audio chip with PCI SSID
0x2292 and codec SSID 0x2292[2]. Given the behavior of
snd_hda_pick_fixup(), it is not possible to have a separate quirk for the
Yoga based on SSID. Therefore, merge the quirks meant for the Carbon and
Yoga. This preserves the current behavior for the Yoga.

[PATCH v5] ima: move APPRAISE_BOOTPARAM dependency on ARCH_POLICY to runtime
by Bruno Meneguele
APPRAISE_BOOTPARAM has been marked as dependent on !ARCH_POLICY in compile
time, enforcing the appraisal whenever the kernel had the arch policy option
enabled.
However it breaks systems where the option is set but the system didn't
boot in a "secure boot" platform. In this scenario, anytime an appraisal
policy (i.e. ima_policy=appraisal_tcb) is used it will be forced, without
giving the user the opportunity to label the filesystem, before enforcing
integrity.
Considering the ARCH_POLICY is only effective when secure boot is actually
enabled this patch remove the compile time dependency and move it to a
runtime decision, based on the secure boot state of that platform.
With this patch:
- x86-64 with secure boot enabled
[ 0.004305] Secure boot enabled
...
[ 0.015651] Kernel command line: <...> ima_policy=appraise_tcb ima_appraise=fix
[ 0.015682] ima: appraise boot param ignored: secure boot enabled
- powerpc with secure boot disabled
[ 0.000000] Kernel command line: <...> ima_policy=appraise_tcb ima_appraise=fix
[ 0.000000] Secure boot mode disabled
...
< nothing about boot param ignored >
System working fine without secure boot and with both options set:
CONFIG_IMA_APPRAISE_BOOTPARAM=y
CONFIG_IMA_ARCH_POLICY=y
Audit logs pointing to "missing-hash" but still being able to execute due to
ima_appraise=fix:

Subject: [PATCH] IB/hfi1: Do not destroy hfi1_wq when the device is shut down
The workqueue hfi1_wq is destroyed in function shutdown_device(), which is
called by either shutdown_one() or remove_one(). The function
shutdown_one() is called when the kernel is rebooted while remove_one() is
called when the hfi1 driver is unloaded. When the kernel is rebooted,
hfi1_wq is destroyed while all qps are still active, leading to a kernel
crash:

The solution is to destroy the workqueue only when the hfi1 driver is
unloaded, not when the device is shut down. In addition, when the device
is shut down, no more work should be scheduled on the workqueues and the
workqueues are flushed.
