Linux 5.4.53
by Greg Kroah-Hartman
I'm announcing the release of the 5.4.53 kernel.
All users of the 5.4 kernel series must upgrade.
The updated 5.4.y git tree can be found at:
git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git linux-5.4.y
and can be browsed at the normal kernel.org git web browser:
https://git.kernel.org/?p=linux/kernel/git/stable/linux-stable.git;a=summary
thanks,
greg k-h

[PATCH v3 00/11] ACPI/NVDIMM: Runtime Firmware Activation
by Dan Williams
Changes since v2 [1]:
- Drop the "mem-quiet" pm-debug interface in favor of an explicit
hibernate_quiet_exec() helper that executes firmware activation, or
any other subsystem provided routine, in a system-quiet context.
(Rafael)
- Rework the sysfs interface to add an explicit trigger to run
activation under hibernate_quiet_exec(). Rename
ndbusX/firmware_activate to ndbusX/firmware/activate, and add a
ndbusX/firmware/capability. Some ndctl reworks are needed to catch up
with this change.
- The new ndbusX/firmware/capability attribute indicates the default
activation method / execution context between "live" and "suspend".

Quoting the documentation:
Some persistent memory devices run a firmware locally on the device /
"DIMM" to perform tasks like media management, capacity provisioning,
and health monitoring. The process of updating that firmware typically
involves a reboot because it has implications for in-flight memory
transactions. However, reboots are disruptive and at least the Intel
persistent memory platform implementation, described by the Intel ACPI
DSM specification [1], has added support for activating firmware at
runtime.
[1]: https://docs.pmem.io/persistent-memory/
The approach taken is to abstract the Intel platform specific mechanism
behind a libnvdimm-generic sysfs interface. The interface could support
runtime-firmware-activation on another architecture without need to
change userspace tooling.
The ACPI NFIT implementation involves a set of device-specific-methods
(DSMs) to 'arm' individual devices for activation and bus-level
'trigger' method to execute the activation. Informational / enumeration
methods are also provided at the bus and device level.
One complicating aspect of the memory device firmware activation is that
the memory controller may need to be quiesced, no memory cycles, during
the activation. While the platform has mechanisms to support holding off
in-flight DMA during the activation, the device response to that delay
is potentially undefined. The platform may reject a runtime firmware
update if, for example a PCI-E device does not support its completion
timeout value being increased to meet the activation time. Outside of
device timeouts the quiesce period may also violate application
timeouts.
Given the above device and application timeout considerations the
implementation uses a new hibernate_quiet_exec() facility to carry-out
firmware activation. This imposes the same conditions that allow for a
stable memory image snapshot to be taken for a hibernate-to-disk
sequence. However, if desired, runtime activation without the hibernate
freeze can be forced as an override.
The ndctl utility grows the following extensions / commands to drive
this mechanism:
1/ The existing update-firmware command will 'arm' devices where the
firmware image is staged by default.
ndctl update-firmware all -f firmware_image.bin
2/ The existing ability to enumerate firmware-update capabilities now
includes firmware activate capabilities at the 'bus' and 'dimm/device'
level:
ndctl list -BDF -b nfit_test.0
[
{
"provider":"nfit_test.0",
"dev":"ndbus2",
"scrub_state":"idle",
"firmware":{
"activate_method":"suspend",
"activate_state":"idle"
},
"dimms":[
{
"dev":"nmem1",
"id":"cdab-0a-07e0-ffffffff",
"handle":0,
"phys_id":0,
"security":"disabled",
"firmware":{
"current_version":0,
"can_update":true
}
},
...
3/ The new activate-firmware command triggers firmware activation per
the platform enumerated context, "suspend" vs "live", or can be forced
to "live" if there is a explicit knowledge that allowing applications
and devices to race the quiesce timeout will have no adverse effects.
ndctl activate-firmware nfit_test.0 [--force]
These patches are passing an updated version of the ndctl
"firmware-update.sh" unit test (to be posted).

[PATCH v2] io-mapping: Indicate mapping failure
by Michael J. Ruhl
The !ATOMIC_IOMAP version of io_maping_init_wc will always return
success, even when the ioremap fails.
Since the ATOMIC_IOMAP version returns NULL when the init fails, and
callers check for a NULL return on error this is unexpected.
During a device probe, where the ioremap failed, a crash can look
like this:
BUG: unable to handle page fault for address: 0000000000210000
#PF: supervisor write access in kernel mode
#PF: error_code(0x0002) - not-present page
Oops: 0002 [#1] PREEMPT SMP
CPU: 0 PID: 177 Comm:
RIP: 0010:fill_page_dma [i915]
gen8_ppgtt_create [i915]
i915_ppgtt_create [i915]
intel_gt_init [i915]
i915_gem_init [i915]
i915_driver_probe [i915]
pci_device_probe
really_probe
driver_probe_device
The remap failure occurred much earlier in the probe. If it had
been propagated, the driver would have exited with an error.
Return NULL on ioremap failure.

[PATCH 1/1] usb: cdns3: gadget: always zeroed TRB buffer when enable endpoint
by Peter Chen
During the endpoint dequeue operation, it changes dequeued TRB
as link TRB, when the endpoint is disabled and re-reabled, the
DMA fetches the TRB before the link TRB, after it handles current
TRB, the DMA pointer will advance to the TRB after link TRB,
but enqueue and dequene variables don't know it due to no hardware
interrupt at the time, when the next TRB is added to link TRB
position, the DMA will not handle this TRB due to its pointer

[tip: x86/urgent] x86, vmlinux.lds: Page-align end of ..page_aligned sections

x86, vmlinux.lds: Page-align end of ..page_aligned sections
On x86-32 the idt_table with 256 entries needs only 2048 bytes. It is
page-aligned, but the end of the .bss..page_aligned section is not
guaranteed to be page-aligned.
As a result, objects from other .bss sections may end up on the same 4k
page as the idt_table, and will accidentially get mapped read-only during
boot, causing unexpected page-faults when the kernel writes to them.
This could be worked around by making the objects in the page aligned
sections page sized, but that's wrong.
Explicit sections which store only page aligned objects have an implicit
guarantee that the object is alone in the page in which it is placed. That
works for all objects except the last one. That's inconsistent.
Enforcing page sized objects for these sections would wreckage memory
sanitizers, because the object becomes artificially larger than it should
be and out of bound access becomes legit.
Align the end of the .bss..page_aligned and .data..page_aligned section on
page-size so all objects places in these sections are guaranteed to have
their own page.

[PATCH v3] Makefile: Fix GCC_TOOLCHAIN_DIR prefix for Clang cross compilation
by Fangrui Song
When CROSS_COMPILE is set (e.g. aarch64-linux-gnu-), if
$(CROSS_COMPILE)elfedit is found at /usr/bin/aarch64-linux-gnu-elfedit,
GCC_TOOLCHAIN_DIR will be set to /usr/bin/. --prefix= will be set to
/usr/bin/ and Clang as of 11 will search for both
$(prefix)aarch64-linux-gnu-$needle and $(prefix)$needle.
GCC searchs for $(prefix)aarch64-linux-gnu/$version/$needle,
$(prefix)aarch64-linux-gnu/$needle and $(prefix)$needle. In practice,
$(prefix)aarch64-linux-gnu/$needle rarely contains executables.
To better model how GCC's -B/--prefix takes in effect in practice, newer
Clang (since
https://github.com/llvm/llvm-project/commit/3452a0d8c17f7166f479706b293caf6…)
only searches for $(prefix)$needle. Currently it will find /usr/bin/as
instead of /usr/bin/aarch64-linux-gnu-as.
Set --prefix= to $(GCC_TOOLCHAIN_DIR)$(CROSS_COMPILE)
(/usr/bin/aarch64-linux-gnu-) so that newer Clang can find the
appropriate cross compiling GNU as (when -no-integrated-as is in
effect).

[PATCH] PCI/ATS: PASID and PRI are only enumerated in PF devices.
by Ashok Raj
PASID and PRI capabilities are only enumerated in PF devices. VF devices
do not enumerate these capabilites. IOMMU drivers also need to enumerate
them before enabling features in the IOMMU. Extending the same support as
PASID feature discovery (pci_pasid_features) for PRI.

v2: Fixed build failure from lkp when CONFIG_PRI=n
Almost all the PRI functions were called only when CONFIG_PASID is
set. Except the new pci_pri_supported().
previous version sent in error because i missed dry-run before recompile

From: Peter Zijlstra <peterz(a)infradead.org>
Subject: mm: fix kthread_use_mm() vs TLB invalidate
For SMP systems using IPI based TLB invalidation, looking at
current->active_mm is entirely reasonable. This then presents the
following race condition:
CPU0 CPU1
flush_tlb_mm(mm) use_mm(mm)
<send-IPI>
tsk->active_mm = mm;
<IPI>
if (tsk->active_mm == mm)
// flush TLBs
</IPI>
switch_mm(old_mm,mm,tsk);
Where it is possible the IPI flushed the TLBs for @old_mm, not @mm,
because the IPI lands before we actually switched.
Avoid this by disabling IRQs across changing ->active_mm and switch_mm().
[ There are all sorts of reasons this might be harmless for various
architecture specific reasons, but best not leave the door open at all. ]

From: "Michael J. Ruhl" <michael.j.ruhl(a)intel.com>
Subject: io-mapping: indicate mapping failure
The !ATOMIC_IOMAP version of io_maping_init_wc will always return success,
even when the ioremap fails.
Since the ATOMIC_IOMAP version returns NULL when the init fails, and
callers check for a NULL return on error this is unexpected.
During a device probe, where the ioremap failed, a crash can look
like this:
BUG: unable to handle page fault for address: 0000000000210000
#PF: supervisor write access in kernel mode
#PF: error_code(0x0002) - not-present page

The remap failure occurred much earlier in the probe. If it had
been propagated, the driver would have exited with an error.
Return NULL on ioremap failure.

[PATCH v2] Makefile: Fix GCC_TOOLCHAIN_DIR prefix for Clang cross compilation
by Fangrui Song
When CROSS_COMPILE is set (e.g. aarch64-linux-gnu-), if
$(CROSS_COMPILE)elfedit is found at /usr/bin/aarch64-linux-gnu-elfedit,
GCC_TOOLCHAIN_DIR will be set to /usr/bin/. --prefix= will be set to
/usr/bin/ and Clang as of 11 will search for both
$(prefix)aarch64-linux-gnu-$needle and $(prefix)$needle.
GCC searchs for $(prefix)aarch64-linux-gnu/$version/$needle,
$(prefix)aarch64-linux-gnu/$needle and $(prefix)$needle. In practice,
$(prefix)aarch64-linux-gnu/$needle rarely contains executables.
To better model how GCC's -B/--prefix takes in effect in practice, newer
Clang (since
https://github.com/llvm/llvm-project/commit/3452a0d8c17f7166f479706b293caf6…)
only searches for $(prefix)$needle. Currently it will find /usr/bin/as
instead of /usr/bin/aarch64-linux-gnu-as.
Set --prefix= to $(GCC_TOOLCHAIN_DIR)$(CROSS_COMPILE)
(/usr/bin/aarch64-linux-gnu-) so that newer Clang can find the
appropriate cross compiling GNU as (when -no-integrated-as is in
effect).

PASID and PRI capabilities are only enumerated in PF devices. VF devices
do not enumerate these capabilites. IOMMU drivers also need to enumerate
them before enabling features in the IOMMU. Extending the same support as
PASID feature discovery (pci_pasid_features) for PRI.

[PATCH v6] ima: move APPRAISE_BOOTPARAM dependency on ARCH_POLICY to runtime
by Bruno Meneguele
The IMA_APPRAISE_BOOTPARAM config allows enabling different "ima_appraise="
modes - log, fix, enforce - at run time, but not when IMA architecture
specific policies are enabled. This prevents properly labeling the
filesystem on systems where secure boot is supported, but not enabled on the
platform. Only when secure boot is actually enabled should these IMA
appraise modes be disabled.
This patch removes the compile time dependency and makes it a runtime
decision, based on the secure boot state of that platform.
Test results as follows:
-> x86-64 with secure boot enabled
[ 0.015637] Kernel command line: <...> ima_policy=appraise_tcb ima_appraise=fix
[ 0.015668] ima: Secure boot enabled: ignoring ima_appraise=fix boot parameter option
-> powerpc with secure boot disabled
[ 0.000000] Kernel command line: <...> ima_policy=appraise_tcb ima_appraise=fix
[ 0.000000] Secure boot mode disabled
-> Running the system without secure boot and with both options set:
CONFIG_IMA_APPRAISE_BOOTPARAM=y
CONFIG_IMA_ARCH_POLICY=y
Audit prompts "missing-hash" but still allow execution and, consequently,
filesystem labeling:

From: Serge Semin <Sergey.Semin(a)baikalelectronics.ru>

Subject: serial: 8250_mtk: Fix high-speed baud rates clamping
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.

SERIAL_PORT_DFNS is not defined on each arch, if it's not defined,
serial8250_set_defaults() won't be called in serial8250_isa_init_ports(),
so the p->serial_in pointer won't be initialized, and it leads a null-ptr-deref.
Fix this problem by calling serial8250_set_defaults() after init uart port.

patch "serial: tegra: fix CREAD handling for PIO" added to tty-linus
by gregkh＠linuxfoundation.org
This is a note to let you know that I've just added the patch titled
serial: tegra: fix CREAD handling for PIO
to my tty git tree which can be found at
git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty.git
in the tty-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 b374c562ee7ab3f3a1daf959c01868bae761571c Mon Sep 17 00:00:00 2001
From: Johan Hovold <johan(a)kernel.org>
Date: Fri, 10 Jul 2020 15:59:46 +0200
Subject: serial: tegra: fix CREAD handling for PIO
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.

patch "tty: xilinx_uartps: Really fix id assignment" added to tty-linus
by gregkh＠linuxfoundation.org
This is a note to let you know that I've just added the patch titled
tty: xilinx_uartps: Really fix id assignment
to my tty git tree which can be found at
git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty.git
in the tty-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: tty: xilinx_uartps: Really fix id assignment
The problems started with the revert (18cc7ac8a28e28). The
cdns_uart_console.index is statically assigned -1. When the port is
registered, Linux assigns consecutive numbers to it. It turned out that
when using ttyPS1 as console, the index is not updated as we are reusing
the same cdns_uart_console instance for multiple ports. When registering
ttyPS0, it gets updated from -1 to 0, but when registering ttyPS1, it
already is 0 and not updated.
That led to 2ae11c46d5fdc4. It assigns the index prior to registering
the uart_driver once. Unfortunately, that ended up breaking the
situation where the probe order does not match the id order. When using
the same device tree for both uboot and linux, it is important that the
serial0 alias points to the console. So some boards reverse those
aliases. This was reported by Jan Kiszka. The proposed fix was reverting
the index assignment and going back to the previous iteration.
However such a reversed assignement (serial0 -> uart1, serial1 -> uart0)
was already partially broken by the revert (18cc7ac8a28e28). While the
ttyPS device works, the kmsg connection is already broken and kernel
messages go missing. Reverting the id assignment does not fix this.
>From the xilinx_uartps driver pov (after reverting the refactoring
commits), there can be only one console. This manifests in static
variables console_pprt and cdns_uart_console. These variables are not
properly linked and can go out of sync. The cdns_uart_console.index is
important for uart_add_one_port. We call that function for each port -
one of which hopefully is the console. If it isn't, the CON_ENABLED flag
is not set and console_port is cleared. The next cdns_uart_probe call
then tries to register the next port using that same cdns_uart_console.
It is important that console_port and cdns_uart_console (and its index
in particular) stay in sync. The index assignment implemented by
Shubhrajyoti Datta is correct in principle. It just may have to happen a
second time if the first cdns_uart_probe call didn't encounter the
console device. And we shouldn't change the index once the console uart
is registered.

Subject: vt: Reject zero-sized screen buffer size.
syzbot is reporting general protection fault in do_con_write() [1] caused
by vc->vc_screenbuf == ZERO_SIZE_PTR caused by vc->vc_screenbuf_size == 0
caused by vc->vc_cols == vc->vc_rows == vc->vc_size_row == 0 caused by
fb_set_var() from ioctl(FBIOPUT_VSCREENINFO) on /dev/fb0 , for
gotoxy(vc, 0, 0) from reset_terminal() from vc_init() from vc_allocate()
from con_install() from tty_init_dev() from tty_open() on such console
causes vc->vc_pos == 0x10000000e due to
((unsigned long) ZERO_SIZE_PTR) + -1U * 0 + (-1U << 1).
I don't think that a console with 0 column or 0 row makes sense. And it
seems that vc_do_resize() does not intend to allow resizing a console to
0 column or 0 row due to
new_cols = (cols ? cols : vc->vc_cols);
new_rows = (lines ? lines : vc->vc_rows);
exception.
Theoretically, cols and rows can be any range as long as
0 < cols * rows * 2 <= KMALLOC_MAX_SIZE is satisfied (e.g.
cols == 1048576 && rows == 2 is possible) because of
vc->vc_size_row = vc->vc_cols << 1;
vc->vc_screenbuf_size = vc->vc_rows * vc->vc_size_row;
in visual_init() and kzalloc(vc->vc_screenbuf_size) in vc_allocate().
Since we can detect cols == 0 or rows == 0 via screenbuf_size = 0 in
visual_init(), we can reject kzalloc(0). Then, vc_allocate() will return
an error, and con_write() will not be called on a console with 0 column
or 0 row.
We need to make sure that integer overflow in visual_init() won't happen.
Since vc_do_resize() restricts cols <= 32767 and rows <= 32767, applying
1 <= cols <= 32767 and 1 <= rows <= 32767 restrictions to vc_allocate()
will be practically fine.
This patch does not touch con_init(), for returning -EINVAL there
does not help when we are not returning -ENOMEM.

[PATCH v1] io-mapping: Indicate mapping failure
by Michael J. Ruhl
The !ATOMIC_IOMAP version of io_maping_init_wc will always return
success, even when the ioremap fails.
Since the ATOMIC_IOMAP version returns NULL when the init fails, and
callers check for a NULL return on error this is unexpected.
Return NULL on ioremap failure.

[PATCH] Smack: fix use-after-free in smk_write_relabel_self()
by Eric Biggers
From: Eric Biggers <ebiggers(a)google.com>
smk_write_relabel_self() frees memory from the task's credentials with
no locking, which can easily cause a use-after-free because multiple
tasks can share the same credentials structure.
Fix this by using prepare_creds() and commit_creds() to correctly modify
the task's credentials.
Reproducer for "BUG: KASAN: use-after-free in smk_write_relabel_self":
#include <fcntl.h>
#include <pthread.h>
#include <unistd.h>
static void *thrproc(void *arg)
{
int fd = open("/sys/fs/smackfs/relabel-self", O_WRONLY);
for (;;) write(fd, "foo", 3);
}
int main()
{
pthread_t t;
pthread_create(&t, NULL, thrproc, NULL);
thrproc(NULL);
}
Reported-by: syzbot+e6416dabb497a650da40(a)syzkaller.appspotmail.com
Fixes: 38416e53936e ("Smack: limited capability for changing process label")

[PATCH AUTOSEL 4.4 1/4] regmap: dev_get_regmap_match(): fix string comparison
by Sasha Levin
From: Marc Kleine-Budde <mkl(a)pengutronix.de>
[ Upstream commit e84861fec32dee8a2e62bbaa52cded6b05a2a456 ]
This function is used by dev_get_regmap() to retrieve a regmap for the
specified device. If the device has more than one regmap, the name parameter
can be used to specify one.
The code here uses a pointer comparison to check for equal strings. This
however will probably always fail, as the regmap->name is allocated via
kstrdup_const() from the regmap's config->name.
Fix this by using strcmp() instead.

[PATCH AUTOSEL 4.9 1/9] HID: i2c-hid: add Mediacom FlexBook edge13 to descriptor override

From: Federico Ricchiuto <fed.ricchiuto(a)gmail.com>
[ Upstream commit 43e666acb79f3d355dd89bf20f4d25d3b15da13e ]
The Mediacom FlexBook edge13 uses the SIPODEV SP1064 touchpad, which does not
supply descriptors, so it has to be added to the override list.

From: Federico Ricchiuto <fed.ricchiuto(a)gmail.com>
[ Upstream commit 43e666acb79f3d355dd89bf20f4d25d3b15da13e ]
The Mediacom FlexBook edge13 uses the SIPODEV SP1064 touchpad, which does not
supply descriptors, so it has to be added to the override list.

[Regression] "SUNRPC: Add "@len" parameter to gss_unwrap()" breaks NFS Kerberos on upstream stable 5.4.y
by Kai-Heng Feng
Hi,
Multiple users reported NFS causes NULL pointer dereference [1] on Ubuntu, due to commit "SUNRPC: Add "@len" parameter to gss_unwrap()" and commit "SUNRPC: Fix GSS privacy computation of auth->au_ralign".
The same issue happens on upstream stable 5.4.y branch.
The mainline kernel doesn't have this issue though.
Should we revert them? Or is there any missing commits need to be backported to v5.4?

[PATCH -stable] MIPS: Fix build for LTS kernel caused by backporting lpj adjustment
by Huacai Chen
Commit ed26aacfb5f71eecb20a ("mips: Add udelay lpj numbers adjustment")
has backported to 4.4~5.4, but the "struct cpufreq_freqs" (and also the
cpufreq notifier machanism) of 4.4~4.19 are different from the upstream
kernel. These differences cause build errors, and this patch can fix the
build.

[PATCH v2] nvme-tcp: 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 stable 4.14.y] arm64: entry: Place an SB sequence following an ERET instruction
by Florian Fainelli
From: Will Deacon <will.deacon(a)arm.com>
commit 679db70801da9fda91d26caf13bf5b5ccc74e8e8 upstream
Some CPUs can speculate past an ERET instruction and potentially perform
speculative accesses to memory before processing the exception return.
Since the register state is often controlled by a lower privilege level
at the point of an ERET, this could potentially be used as part of a
side-channel attack.
This patch emits an SB sequence after each ERET so that speculation is
held up on exception return.

efi/arm: Defer probe of PCIe backed efifb on DT systems
[ Upstream commit 64c8a0cd0a535891d5905c3a1651150f0f141439 ]
The new of_devlink support breaks PCIe probing on ARM platforms booting
via UEFI if the firmware exposes a EFI framebuffer that is backed by a
PCI device. The reason is that the probing order gets reversed,
resulting in a resource conflict on the framebuffer memory window when
the PCIe probes last, causing it to give up entirely.
Given that we rely on PCI quirks to deal with EFI framebuffers that get
moved around in memory, we cannot simply drop the memory reservation, so
instead, let's use the device link infrastructure to register this
dependency, and force the probing to occur in the expected order.

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
by Sergey Senozhatsky
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.

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.

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.
Fixes: 349d39dc5739 ("thermal: cpu_cooling: merge frequency and power tables")

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

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.
+
+[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] 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] 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:
+

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."
v1: first non-RFC version
- Disable raw_violation_fixup and fully remove unused code and macros

[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.
Fixes: c30da2e981a7 ("fuse: convert to use the new mount API")

[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.

patch "staging: comedi: addi_apci_1564: 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_1564: 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_1564: 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.

The TRM mentions GPIO_1 pad should be muxed/assigned for card detect
and ENET_RX_ER pad for USB_OTG_ID for proper operation.
