[ Upstream commit 914adbb1bcf89478ac138318d28b302704564d59 ]
GRE entropy calculation is a single bit per card, and not per port.
Force disable GRE entropy calculation upon the first GRE encap rule,
and release the force at the last GRE encap rule removal. This is done
per port.

[ Upstream commit 107e47cc80ec37cb332bd41b22b1c7779e22e018 ]
vrf_process_v4_outbound() and vrf_process_v6_outbound() do routing
using ip/ipv6 addresses, but don't make sure the header is available
in skb->data[] (skb_headlen() is less then header size).
Case:
1) igb driver from intel.
2) Packet size is greater then 255.
3) MPLS forwards to VRF device.
So, patch adds pskb_may_pull() calls in vrf_process_v4/v6_outbound()
functions.

[ Upstream commit a261e3797506bd561700be643fe1a85bf81e9661 ]
The onboard sky2 NIC on ASUS P6T WS PRO doesn't work after PM resume
due to the infamous IRQ problem. Disabling MSI works around it, so
let's add it to the blacklist.
Unfortunately the BIOS on the machine doesn't fill the standard
DMI_SYS_* entry, so we pick up DMI_BOARD_* entries instead.

[ Upstream commit 4993e5b37e8bcb55ac90f76eb6d2432647273747 ]
Ben Hutchings says:
"This is the wrong place to change the queue mapping.
stmmac_xmit() is called with a specific TX queue locked,
and accessing a different TX queue results in a data race
for all of that queue's state.
I think this commit should be reverted upstream and in all
stable branches. Instead, the driver should implement the
ndo_select_queue operation and override the queue mapping there."

[ Upstream commit 35cbef9863640f06107144687bd13151bc2e8ce3 ]
Currently we silently ignore filters if we cannot meet the filter
requirements. This will lead to the MAC dropping packets that are
expected to pass. A better solution would be to set the NIC to promisc
mode when the required filters cannot be met.
Also correct the number of MDF filters supported. It should be 17,
not 16.

commit bd293d071ffe65e645b4d8104f9d8fe15ea13862 upstream.
When thin-volume is built on loop device, if available memory is low,
the following deadlock can be triggered:
One process P1 allocates memory with GFP_FS flag, direct alloc fails,
memory reclaim invokes memory shrinker in dm_bufio, dm_bufio_shrink_scan()
runs, mutex dm_bufio_client->lock is acquired, then P1 waits for dm_buffer
IO to complete in __try_evict_buffer().
But this IO may never complete if issued to an underlying loop device
that forwards it using direct-IO, which allocates memory using
GFP_KERNEL (see: do_blockdev_direct_IO()). If allocation fails, memory
reclaim will invoke memory shrinker in dm_bufio, dm_bufio_shrink_scan()
will be invoked, and since the mutex is already held by P1 the loop
thread will hang, and IO will never complete. Resulting in ABBA
deadlock.

commit e244c4699f859cf7149b0781b1894c7996a8a1df upstream.
With Link Power Management (LPM) enabled USB3 links transition to low
power U1/U2 link states from U0 state automatically.
Current hub code detects USB3 remote wakeups by checking if the software
state still shows suspended, but the link has transitioned from suspended
U3 to enabled U0 state.
As it takes some time before the hub thread reads the port link state
after a USB3 wake notification, the link may have transitioned from U0
to U1/U2, and wake is not detected by hub code.
Fix this by handling U1/U2 states in the same way as U0 in USB3 wakeup
handling
This patch should be added to stable kernels since 4.13 where LPM was
kept enabled during suspend/resume

commit e1884ffddacc0424d7e785e6f8087bd12f7196db upstream.
At present, the flow of calculating AC timing of read/write cycle in SDR
mode is that:
At first, calculate high hold time which is valid for both read and write
cycle using the max value between tREH_min and tWH_min.
Secondly, calculate WE# pulse width using tWP_min.
Thridly, calculate RE# pulse width using the bigger one between tREA_max
and tRP_min.
But NAND SPEC shows that Controller should also meet write/read cycle time.
That is write cycle time should be more than tWC_min and read cycle should
be more than tRC_min. Obviously, we do not achieve that now.
This patch corrects the low level time calculation to meet minimum
read/write cycle time required. After getting the high hold time, WE# low
level time will be promised to meet tWP_min and tWC_min requirement,
and RE# low level time will be promised to meet tREA_max, tRP_min and
tRC_min requirement.

commit 7e3e888dfc138089f4c15a81b418e88f0978f744 upstream.
At namespace creation time there is the potential for the "expected to
be zero" fields of a 'pfn' info-block to be filled with indeterminate
data. While the kernel buffer is zeroed on allocation it is immediately
overwritten by nd_pfn_validate() filling it with the current contents of
the on-media info-block location. For fields like, 'flags' and the
'padding' it potentially means that future implementations can not rely on
those fields being zero.
In preparation to stop using the 'start_pad' and 'end_trunc' fields for
section alignment, arrange for fields that are not explicitly
initialized to be guaranteed zero. Bump the minor version to indicate
it is safe to assume the 'padding' and 'flags' are zero. Otherwise,
this corruption is expected to benign since all other critical fields
are explicitly initialized.
Note The cc: stable is about spreading this new policy to as many
kernels as possible not fixing an issue in those kernels. It is not
until the change titled "libnvdimm/pfn: Stop padding pmem namespaces to
section alignment" where this improper initialization becomes a problem.
So if someone decides to backport "libnvdimm/pfn: Stop padding pmem
namespaces to section alignment" (which is not tagged for stable), make
sure this pre-requisite is flagged.

Currently, the driver will attempt to set the mode on all
devices with a center button, but some devices with a center
button lack LEDs, and attempting to set the LEDs on devices
without LEDs results in the kernel error message of the form:
"leds input8::wacom-0.1: Setting an LED's brightness failed (-32)"
This is because the generic codepath erroneously assumes that the
BUTTON_CENTER usage indicates that the device has LEDs, the
previously ignored TOUCH_RING_SETTING usage is a more accurate
indication of the existence of LEDs on the device.

commit 64adde31c8e996a6db6f7a1a4131180e363aa9f2 upstream.
Currently, there is only a 1 ms sleep after asserting PERST.
Reading the datasheets for different endpoints, some require PERST to be
asserted for 10 ms in order for the endpoint to perform a reset, others
require it to be asserted for 50 ms.
Several SoCs using this driver uses PCIe Mini Card, where we don't know
what endpoint will be plugged in.
The PCI Express Card Electromechanical Specification r2.0, section
2.2, "PERST# Signal" specifies:
"On power up, the deassertion of PERST# is delayed 100 ms (TPVPERL) from
the power rails achieving specified operating limits."
Add a sleep of 100 ms before deasserting PERST, in order to ensure that
we are compliant with the spec.

commit 000dd5316e1c756a1c028f22e01d06a38249dd4d upstream.
PME polling does not take into account that a device that is directly
connected to the host bridge may go into D3cold as well. This leads to a
situation where the PME poll thread reads from a config space of a
device that is in D3cold and gets incorrect information because the
config space is not accessible.
Here is an example from Intel Ice Lake system where two PCIe root ports
are in D3cold (I've instrumented the kernel to log the PMCSR register

Since 0xffff is interpreted so that PME is pending, the root ports will
be runtime resumed. This repeats over and over again essentially
blocking all runtime power management.
Prevent this from happening by checking whether the device is in D3cold
before its PME status is read.

commit bcef5b7215681250c4bf8961dfe15e9e4fef97d0 upstream.
The function srp_parse_in() is used both for parsing source address

must have a port number. Having to specify a port number for source
addresses is inconvenient. Make sure that srp_parse_in() supports again

commit e28ad544f462231d3fd081a7316339359efbb481 upstream.
DisplayID blocks allow embedding of CEA blocks. The payloads are
identical to traditional top level CEA extension blocks, but the header
is slightly different.
This change allows the CEA parser to find a CEA block inside a DisplayID
block. Additionally, it adds support for parsing the embedded CTA
header. No further changes are necessary due to payload parity.
This change fixes audio support for the Valve Index HMD.

commit 41a531ffa4c5aeb062f892227c00fabb3b4a9c91 upstream.
Since commit ed194d136769 ("usb: core: remove local_irq_save() around
->complete() handler") the handler rt2x00usb_interrupt_rxdone() is
not running with interrupts disabled anymore. So this completion handler
is not guaranteed to run completely before workqueue processing starts
for the same queue entry.
Be sure to set all other flags in the entry correctly before marking
this entry ready for workqueue processing. This way we cannot miss error
conditions that need to be signalled from the completion handler to the
worker thread.
Note that rt2x00usb_work_rxdone() processes all available entries, not
only such for which queue_work() was called.
This patch is similar to what commit df71c9cfceea ("rt2x00: fix order
of entry flags modification") did for TX processing.
This fixes a regression on a RT5370 based wifi stick in AP mode, which
suddenly stopped data transmission after some period of heavy load. Also
stopping the hanging hostapd resulted in the error message "ieee80211
phy0: rt2x00queue_flush_queue: Warning - Queue 14 failed to flush".
Other operation modes are probably affected as well, this just was
the used testcase.

commit 3b8cafdd5436f9298b3bf6eb831df5eef5ee82b6 upstream.
dm-zoned uses the zone flag DMZ_ACTIVE to indicate that a zone of the
backend device is being actively read or written and so cannot be
reclaimed. This flag is set as long as the zone atomic reference
counter is not 0. When this atomic is decremented and reaches 0 (e.g.
on BIO completion), the active flag is cleared and set again whenever
the zone is reused and BIO issued with the atomic counter incremented.
These 2 operations (atomic inc/dec and flag set/clear) are however not
always executed atomically under the target metadata mutex lock and
this causes the warning:
WARN_ON(!test_bit(DMZ_ACTIVE, &zone->flags));
in dmz_deactivate_zone() to be displayed. This problem is regularly
triggered with xfstests generic/209, generic/300, generic/451 and
xfs/077 with XFS being used as the file system on the dm-zoned target
device. Similarly, xfstests ext4/303, ext4/304, generic/209 and
generic/300 trigger the warning with ext4 use.
This problem can be easily fixed by simply removing the DMZ_ACTIVE flag
and managing the "ACTIVE" state by directly looking at the reference
counter value. To do so, the functions dmz_activate_zone() and
dmz_deactivate_zone() are changed to inline functions respectively
calling atomic_inc() and atomic_dec(), while the dmz_is_active() macro
is changed to an inline function calling atomic_read().

commit 7cb95eeea6706c790571042a06782e378b2561ea upstream.
It turns out that while disabling i2c bus access from software when the
GPU is suspended was a step in the right direction with:
commit 342406e4fbba ("drm/nouveau/i2c: Disable i2c bus access after
->fini()")
We also ended up accidentally breaking the vbios init scripts on some
older Tesla GPUs, as apparently said scripts can actually use the i2c
bus. Since these scripts are executed before initializing any
subdevices, we end up failing to acquire access to the i2c bus which has
left a number of cards with their fan controllers uninitialized. Luckily
this doesn't break hardware - it just means the fan gets stuck at 100%.
This also means that we've always been using our i2c busses before
initializing them during the init scripts for older GPUs, we just didn't
notice it until we started preventing them from being used until init.
It's pretty impressive this never caused us any issues before!
So, fix this by initializing our i2c pad and busses during subdev
pre-init. We skip initializing aux busses during pre-init, as those are
guaranteed to only ever be used by nouveau for DP aux transactions.

commit 70f1b0d34bdf03065fe869e93cc17cad1ea20c4a upstream.
The usb support for asyncio encoded one of it's values in the wrong
field. It should have used si_value but instead used si_addr which is
not present in the _rt union member of struct siginfo.
The practical result of this is that on a 64bit big endian kernel
when delivering a signal to a 32bit process the si_addr field
is set to NULL, instead of the expected pointer value.
This issue can not be fixed in copy_siginfo_to_user32 as the usb
usage of the the _sigfault (aka si_addr) member of the siginfo
union when SI_ASYNCIO is set is incompatible with the POSIX and
glibc usage of the _rt member of the siginfo union.
Therefore replace kill_pid_info_as_cred with kill_pid_usb_asyncio a
dedicated function for this one specific case. There are no other
users of kill_pid_info_as_cred so this specialization should have no
impact on the amount of code in the kernel. Have kill_pid_usb_asyncio
take instead of a siginfo_t which is difficult and error prone, 3
arguments, a signal number, an errno value, and an address enconded as
a sigval_t. The encoding of the address as a sigval_t allows the
code that reads the userspace request for a signal to handle this
compat issue along with all of the other compat issues.
Add BUILD_BUG_ONs in kernel/signal.c to ensure that we can now place
the pointer value at the in si_pid (instead of si_addr). That is the
code now verifies that si_pid and si_addr always occur at the same
location. Further the code veries that for native structures a value
placed in si_pid and spilling into si_uid will appear in userspace in
si_addr (on a byte by byte copy of siginfo or a field by field copy of
siginfo). The code also verifies that for a 64bit kernel and a 32bit
userspace the 32bit pointer will fit in si_pid.
I have used the usbsig.c program below written by Alan Stern and
slightly tweaked by me to run on a big endian machine to verify the
issue exists (on sparc64) and to confirm the patch below fixes the issue.

commit 14f28f5cea9e3998442de87846d1907a531b6748 upstream.
buf->size is an unsigned long; casting that to int will lead to an
overflow if buf->size exceeds INT_MAX.
Fix this by changing the type to unsigned long instead. This is possible
as the buf->size is always aligned to PAGE_SIZE, and therefore the size
will never have values lesser than 0.

commit 17ce302f3117e9518395847a3120c8a108b587b8 upstream.
In the presence of any form of instrumentation, nmi_enter() should be
done before calling any traceable code and any instrumentation code.
Currently, nmi_enter() is done in handle_domain_nmi(), which is much
too late as instrumentation code might get called before. Move the
nmi_enter/exit() calls to the arch IRQ vector handler.
On arm64, it is not possible to know if the IRQ vector handler was
called because of an NMI before acknowledging the interrupt. However, It
is possible to know whether normal interrupts could be taken in the
interrupted context (i.e. if taking an NMI in that context could
introduce a potential race condition).
When interrupting a context with IRQs disabled, call nmi_enter() as soon
as possible. In contexts with IRQs enabled, defer this to the interrupt
controller, which is in a better position to know if an interrupt taken
is an NMI.

commit c56e00a3feaee2b46b7d33875fb7f52efd30241f upstream.
In AP (and IBSS) mode, we can only set GTKs to firmware after we have
sent down the multicast station, but this we can only do after we've
enabled beaconing, etc.
However, during rfkill exit, hostapd will configure the keys before
starting the AP, and cfg80211/mac80211 accept it happily.
On earlier devices, this didn't bother us as GTK TX wasn't really
handled in firmware, we just put the key material into the TX cmd
and thus it only mattered when we actually transmitted a frame.
On newer devices, however, the firmware needs to track all of this
and that doesn't work if we add the key before the (multicast) sta
it belongs to.
To fix this, keep a list of keys to add during AP enable, and call
the function there.

commit ed3e4c6d3cd8f093a3636cb05492429fe2af228d upstream.
Newest devices have a new firmware load mechanism. This
mechanism is called the context info. It means that the
driver doesn't need to load the sections of the firmware.
The driver rather prepares a place in DRAM, with pointers
to the relevant sections of the firmware, and the firmware
loads itself.
At the end of the process, the firmware sends the ALIVE
interrupt. This is different from the previous scheme in
which the driver expected the FH_TX interrupt after each
section being transferred over the DMA.
In order to support this new flow, we enabled all the
interrupts. This broke the assumption that we have in the
code that the RF-Kill interrupt can't interrupt the firmware
load flow.
Change the context info flow to enable only the ALIVE
interrupt, and re-enable all the other interrupts only
after the firmware is alive. Then, we won't see the RF-Kill
interrupt until then. Getting the RF-Kill interrupt while
loading the firmware made us kill the firmware while it is
loading and we ended up dumping garbage instead of the firmware
state.
Re-enable the ALIVE | RX interrupts from the ISR when we
get the ALIVE interrupt to be able to get the RX interrupt
that comes immediately afterwards for the ALIVE
notification. This is needed for non MSI-X only.
