[ Upstream commit 259bdba27e32368b4404f69d613b1c1014c07cbf ]
The vxcan driver provides a pair of virtual CAN interfaces to exchange
CAN traffic between different namespaces - analogue to veth.
In opposite to the vcan driver the local sent CAN traffic on this interface
is not echo'ed back but only sent to the remote peer. This is unusual and
can be easily fixed by removing IFF_ECHO from the netdevice flags that
are set for vxcan interfaces by default at startup.
Without IFF_ECHO set on driver level, the local sent CAN frames are echo'ed
in af_can.c in can_send(). This patch makes vxcan interfaces adopt the
same local echo behavior and procedures as known from the vcan interfaces.
Fixes: a8f820a380a2 ("can: add Virtual CAN Tunnel driver (vxcan)")

[ Upstream commit d23a8720327d33616f584d76c80824bfa4699be6 ]
In test_lwt_ip_encap, the ingress IPv6 encap test failed from time to
time. The failure occured when an IPv4 ping through the IPv6 GRE
encapsulation did not receive a reply within the timeout. The IPv4 ping
and the IPv6 ping in the test used different timeouts (1 sec for IPv4
and 6 sec for IPv6), probably taking into account that IPv6 might need
longer to successfully complete. However, when IPv4 pings (with the
short timeout) are encapsulated into the IPv6 tunnel, the delays of IPv6
apply.
The actual reason for the long delays with IPv6 was that the IPv6
neighbor discovery sometimes did not complete in time. This was caused
by the outgoing interface only having a tentative link local address,
i.e., not having completed DAD for that lladdr. The ND was successfully
retried after 1 sec but that was too late for the ping timeout.
The IPv6 addresses for the test were already added with nodad. However,
for the lladdrs, DAD was still performed. We now disable DAD in the test
netns completely and just assume that the two lladdrs on each veth pair
do not collide. This removes all the delays for IPv6 traffic in the
test.
Without the delays, we can now also reduce the delay of the IPv6 ping to
1 sec. This makes the whole test complete faster because we don't need
to wait for the excessive timeout for each IPv6 ping that is supposed
to fail.

[ Upstream commit 9c6e6a80ee741adf6cb3cfd8eef7d1554f91fceb ]
xsk_umem__create() does mmap for fill/comp rings, but xsk_umem__delete()
doesn't do the unmap. This works fine for regular cases, because
xsk_socket__delete() does unmap for the rings. But for the case that
xsk_socket__create_shared() fails, umem rings are not unmapped.
fill_save/comp_save are checked to determine if rings have already be
unmapped by xsk. If fill_save and comp_save are NULL, it means that the
rings have already been used by xsk. Then they are supposed to be
unmapped by xsk_socket__delete(). Otherwise, xsk_umem__delete() does the
unmap.

[ Upstream commit 7a7d340ba4d9351e4c8847b898a2b996727a922a ]
If a memory allocation error occurred during an attempt to refill a slot
in the RX ring after the packet was received, the hardware tail pointer
would still have been updated to point to or past the slot which remained
marked as previously completed. This would likely result in the DMA engine
raising an error when it eventually tried to use that slot again.
If a slot cannot be refilled, then just stop processing and do not move
the tail pointer past it. On the next attempt, we should skip receiving
the packet from the empty slot and just try to refill it again.
This failure mode has not actually been observed, but was found as part
of other driver updates.

[ Upstream commit 92c45b63ce22c8898aa41806e8d6692bcd577510 ]
For hardware that only supports 32-bit writes to PCI there is the
possibility of clearing RW1C (write-one-to-clear) bits. A rate-limited
messages was introduced by fb2659230120, but rate-limiting is not the best
choice here. Some devices may not show the warnings they should if another
device has just produced a bunch of warnings. Also, the number of messages
can be a nuisance on devices which are otherwise working fine.
Change the ratelimit to a single warning per bus. This ensures no bus is
'starved' of emitting a warning and also that there isn't a continuous
stream of warnings. It would be preferable to have a warning per device,
but the pci_dev structure is not available here, and a lookup from devfn
would be far too slow.

This driver is for an FPGA logic core, so there can be arbitrarily many
instances of the bus on a given system. Previously all of the I2C bus
names were "xiic-i2c" which caused issues with lm_sensors when trying to

distinguish the busses, for example. Append the platform device name to
the I2C bus name so it is unique between different instances.

[ Upstream commit f66af9f222f08d5b11ea41c1bd6c07a0f12daa07 ]
In emulation of writing to cr8, one of the lowest four bits in TPR[3:0]
is kept.
According to Intel SDM 10.8.6.1(baremetal scenario):
"APIC.TPR[bits 7:4] = CR8[bits 3:0], APIC.TPR[bits 3:0] = 0";
and SDM 28.3(use TPR shadow):
"MOV to CR8. The instruction stores bits 3:0 of its source operand into
bits 7:4 of VTPR; the remainder of VTPR (bits 3:0 and bits 31:8) are
cleared.";
and AMD's APM 16.6.4:
"Task Priority Sub-class (TPS)-Bits 3 : 0. The TPS field indicates the
current sub-priority to be used when arbitrating lowest-priority messages.
This field is written with zero when TPR is written using the architectural
CR8 register.";
so in KVM emulated scenario, clear TPR[3:0] to make a consistent behavior
as in other scenarios.
This doesn't impact evaluation and delivery of pending virtual interrupts
because processor does not use the processor-priority sub-class to
determine which interrupts to delivery and which to inhibit.
Sub-class is used by hardware to arbitrate lowest priority interrupts,
but KVM just does a round-robin style delivery.

[ Upstream commit 2863dd2db23e0407f6c50b8ba5c0e55abef894f1 ]
When CONFIG_GENERIC_CPU=y (true for all our defconfigs) we pass
-mcpu=powerpc64 to the compiler, even when we're building a 32-bit
kernel.
This happens because we have an ifdef CONFIG_PPC_BOOK3S_64/else block in
the Makefile that was written before 32-bit supported GENERIC_CPU. Prior
to that the else block only applied to 64-bit Book3E.
The GCC man page says -mcpu=powerpc64 "[specifies] a pure ... 64-bit big
endian PowerPC ... architecture machine [type], with an appropriate,
generic processor model assumed for scheduling purposes."
It's unclear how that interacts with -m32, which we are also passing,
although obviously -m32 is taking precedence in some sense, as the
32-bit kernel only contains 32-bit instructions.
This was noticed by inspection, not via any bug reports, but it does
affect code generation. Comparing before/after code generation, there
are some changes to instruction scheduling, and the after case (with
-mcpu=powerpc64 removed) the compiler seems more keen to use r8.
Fix it by making the else case only apply to Book3E 64, which excludes
32-bit.

[ Upstream commit 749ed4a20657bcea66a6e082ca3dc0d228cbec80 ]
Executing node_set_online() when nid = NUMA_NO_NODE results in an
undefined behavior. node_set_online() will call node_set_state(), into
__node_set(), into set_bit(), and since NUMA_NO_NODE is -1 we'll end up
doing a negative shift operation inside
arch/powerpc/include/asm/bitops.h. This potential UB was detected
running a kernel with CONFIG_UBSAN.
The behavior was introduced by commit 10f78fd0dabb ("powerpc/numa: Fix a
regression on memoryless node 0"), where the check for nid > 0 was
removed to fix a problem that was happening with nid = 0, but the result
is that now we're trying to online NUMA_NO_NODE nids as well.
Checking for nid >= 0 will allow node 0 to be onlined while avoiding
this UB with NUMA_NO_NODE.

[ Upstream commit f7731754fdce33dad19be746f647d6ac47c5d695 ]
The datasheet says that the BQ24190_REG_POC_CHG_CONFIG bits can
have a value of either 10(0x2) or 11(0x3) for OTG (5V boost regulator)
mode.
Sofar bq24190_vbus_is_enabled() was only checking for 10 but some BIOS-es
uses 11 when enabling the regulator at boot.
Make bq24190_vbus_is_enabled() also check for 11 so that it does not
wrongly returns false when the bits are set to 11.

[ Upstream commit 50b3a818991074177a56c87124c7a7bdf5fa4f67 ]
We need to calculate the max file size accurately if the total blocks
that can address by block tree exceed the upper_limit. But this check is
not correct now, it only compute the total data blocks but missing
metadata blocks are needed. So in the case of "data blocks < upper_limit
&& total blocks > upper_limit", we will get wrong result. Fortunately,
this case could not happen in reality, but it's confused and better to
correct the computing.

[ Upstream commit 39844b7e3084baecef52d1498b5fa81afa2cefa9 ]
__setup() handlers should return 1 if the parameter is handled.
Returning 0 causes the entire string to be added to init's
environment strings (limited to 32 strings), unnecessarily polluting it.
Using the documented strings "TOMOYO_loader=string1" and
"TOMOYO_trigger=string2" causes an Unknown parameter message:
Unknown kernel command line parameters
"BOOT_IMAGE=/boot/bzImage-517rc5 TOMOYO_loader=string1 \
TOMOYO_trigger=string2", will be passed to user space.
and these strings are added to init's environment string space:
Run /sbin/init as init process
with arguments:
/sbin/init
with environment:
HOME=/
TERM=linux
BOOT_IMAGE=/boot/bzImage-517rc5
TOMOYO_loader=string1
TOMOYO_trigger=string2
With this change, these __setup handlers act as expected,
and init's environment is not polluted with these strings.

[ Upstream commit 1d6736c3e162061dc811c76e605f35ef3234bffa ]
NCQ NON DATA is an NCQ command with the DMA_NONE DMA direction and so a
register-device-to-host-FIS response is expected for it.
However, for an IO_SUCCESS case, mpi_sata_completion() expects a
set-device-bits-FIS for any ata task with an use_ncq field true, which
includes NCQ NON DATA commands.
Fix this to correctly treat NCQ NON DATA commands as non-data by also
testing for the DMA_NONE DMA direction.

In the pm8001_chip_sata_req() and pm80xx_chip_sata_req() functions, all
tasks with a DMA direction of DMA_NONE (no data transfer) are initialized
using the ATAP value 0x04. However, NCQ NON DATA commands, while being
DMA_NONE commands are NCQ commands and need to be initialized using the
value 0x07 for ATAP, similarly to other NCQ commands.
Make sure that NCQ NON DATA command tasks are initialized similarly to
other NCQ commands by also testing the task "use_ncq" field in addition to
the DMA direction. While at it, reorganize the code into a chain of if -
else if - else to avoid useless affectations and debug messages.

[ Upstream commit cd2268a180117aa8ebb23e090ba204324b2d0e93 ]
The ds_ads_m field of struct ssp_ini_tm_start_req has the type __le32.
Assigning a value to it should thus use cpu_to_le32(). This fixes the
sparse warning:
warning: incorrect type in assignment (different base types)
expected restricted __le32 [addressable] [assigned] [usertype] ds_ads_m
got int

[ Upstream commit 1a37b6738b58d86f6b144b3fc754ace0f2e0166d ]
Since the sata_cmd struct is zeroed out before its fields are initialized,
there is no need for using "|=" to initialize the ncqtag_atap_dir_m
field. Using a standard assignment removes the sparse warning:
warning: invalid assignment: |=
Also, since the ncqtag_atap_dir_m field has type __le32, use cpu_to_le32()
to generate the assigned value.
