[ Upstream commit 2191b1dfef7d45f44b5008d2148676d9f2c82874 ]
When link modes were initially added in commit 2c762679435dc
("net/mlx4_en: Use PTYS register to query ethtool settings") and
later updated for the new ethtool API in commit 3d8f7cc78d0eb
("net: mlx4: use new ETHTOOL_G/SSETTINGS API") the only 1/10G non-baseT
link modes configured were 1000baseKX, 10000baseKX4 and 10000baseKR.
It looks like these got picked to represent other modes since nothing
better was available.
Switch to using more specific link modes added in commit 5711a98221443
("net: ethtool: add support for 1000BaseX and missing 10G link modes").
Tested with MCX311A-XCAT connected via DAC.

[ Upstream commit 4e9679738a918d8a482ac6a2cb2bb871f094bb84 ]
Revert commit b4b844930f27 ("tty: serial: fsl_lpuart: drop earlycon entry
for i.MX8QXP"), because this breaks earlycon support on imx8qm/imx8qxp.
While it is true that for earlycon there is no difference between
i.MX8QXP and i.MX7ULP (for now at least), there are differences
regarding clocks and fixups for wakeup support. For that reason it was
deemed unacceptable to add the imx7ulp compatible to device tree in
order to get earlycon working again.

[ Upstream commit 53ae7230918154d1f4281d7aa3aae9650436eadf ]
Building with clang & LLVM_IAS=1 leads to an error:
arch/s390/lib/test_unwind.c:179:4: error: invalid register pair
" mvcl %%r1,%%r1\n"
^
The test creates an invalid instruction that would trap at runtime, but the
LLVM inline assembler tries to validate it at compile time too.
Use the raw instruction opcode instead.

[ Upstream commit 83bb2c1a01d7127d5adc7d69d7aaa3f7072de2b4 ]
In order to be able to use primitives such as vcpu_mode_is_32bit(),
we need to synchronize the guest PSTATE. However, this is currently
done deep into the bowels of the world-switch code, and we do have
helpers evaluating this much earlier (__vgic_v3_perform_cpuif_access
and handle_aarch32_guest, for example).
Move the saving of the guest pstate into the early fixups, which
cures the first issue. The second one will be addressed separately.

[ Upstream commit cd92cc187c053ab010a1570e2d61d68394a5c725 ]
If "data_lanes" property of the dsi output endpoint is missing in
the DT, num_data_lanes would be 0 by default, which could cause
dsi_host_attach() to fail if dsi->lanes is set to a non-zero value
by the bridge driver.
According to the binding document of msm dsi controller, the
input/output endpoint of the controller is expected to have 4 lanes.
So let's set num_data_lanes to 4 by default.

commit 9b6164342e981d751e69f5a165dd596ffcdfd6fe upstream.
This document was written a long time ago. Update it.
[1] Drop the version information
The range of the supported GCC versions are always changing. The
current minimal GCC version is 4.9, and commit 1e860048c53e
("gcc-plugins: simplify GCC plugin-dev capability test") removed the
old code accordingly.
We do not need to mention specific version ranges like "all gcc versions
from 4.5 to 6.0" since we forget to update the documentation when we
raise the minimal compiler version.
[2] Drop the C compiler statements
Since commit 77342a02ff6e ("gcc-plugins: drop support for GCC <= 4.7")
the GCC plugin infrastructure only supports g++.
[3] Drop supported architectures
As of v5.11-rc4, the infrastructure supports more architectures;
arm, arm64, mips, powerpc, riscv, s390, um, and x86. (just grep
"select HAVE_GCC_PLUGINS") Again, we miss to update this document when a
new architecture is supported. Let's just say "only some architectures".
[4] Update the apt-get example
We are now discussing to bump the minimal version to GCC 5. The GCC 4.9
support will be removed sooner or later. Change the package example to
gcc-10-plugin-dev while we are here.
[5] Update the build target
Since commit ce2fd53a10c7 ("kbuild: descend into scripts/gcc-plugins/
via scripts/Makefile"), "make gcc-plugins" is not supported.
"make scripts" builds all the enabled plugins, including some other
tools.
[6] Update the steps for adding a new plugin
At first, all CONFIG options for GCC plugins were located in arch/Kconfig.
After commit 45332b1bdfdc ("gcc-plugins: split out Kconfig entries to
scripts/gcc-plugins/Kconfig"), scripts/gcc-plugins/Kconfig became the
central place to collect plugin CONFIG options. In my understanding,
this requirement no longer exists because commit 9f671e58159a ("security:
Create "kernel hardening" config area") moved some of plugin CONFIG
options to another file. Find an appropriate place to add the new CONFIG.
The sub-directory support was never used by anyone, and removed by
commit c17d6179ad5a ("gcc-plugins: remove unused GCC_PLUGIN_SUBDIR").
Remove the useless $(src)/ prefix.

commit b560b21f71eb4ef9dfc7c8ec1d0e4d7f9aa54b51 upstream.
This commit adds BPF verifier selftests that cover all corner cases by
packet boundary checks. Specifically, 8-byte packet reads are tested at
the beginning of data and at the beginning of data_meta, using all kinds
of boundary checks (all comparison operators: <, >, <=, >=; both
permutations of operands: data + length compared to end, end compared to
data + length). For each case there are three tests:
1. Length is just enough for an 8-byte read. Length is either 7 or 8,
depending on the comparison.
2. Length is increased by 1 - should still pass the verifier. These
cases are useful, because they failed before commit 2fa7d94afc1a
("bpf: Fix the off-by-two error in range markings").
3. Length is decreased by 1 - should be rejected by the verifier.
Some existing tests are just renamed to avoid duplication.

commit 3a1bf591e9a410f220b7405a142a47407394a1d5 upstream.
The buffer list is sorted and this is not being considered while
calculating packet size. This would lead to improper copy length
calculation for non-dmaheap buffers which would eventually cause
sending improper buffers to DSP.

commit b383a42ca523ce54bcbd63f7c8f3cf974abc9b9a upstream.
INVALL CMD specifies that the ITS must ensure any caching associated with
the interrupt collection defined by ICID is consistent with the LPI
configuration tables held in memory for all Redistributors. SYNC is
required to ensure that INVALL is executed.
Currently, LPI configuration data may be inconsistent with that in the
memory within a short period of time after the INVALL command is executed.

IIO trigger handlers must call iio_trigger_notify_done() when done. This
must be done even when an error occurred. Otherwise the trigger will be
seen as busy indefinitely and the trigger handler will never be called

is an error reading the converter data. Fix this by making sure that
iio_trigger_notify_done() is included in the error exit path.

It's also confirmed by vendor BSP (axp20x_adc.c:axp22_icharge_to_mA).
The scale factor of 0.5 is never mentioned in datasheet, nor in the

commit f711f28e71e965c0d1141c830fa7131b41abbe75 upstream.
Some I/Os are connected to ADC input channels, when the corresponding bit
in PCSEL register are set on STM32H7 and STM32MP15. This is done in the
prepare routine of stm32-adc driver.
There are constraints here, as PCSEL shouldn't be set when VDDA supply
is disabled. Enabling/disabling of VDDA supply in done via stm32-adc-core
runtime PM routines (before/after ADC is enabled/disabled).
Currently, PCSEL remains set when disabling ADC. Later on, PM runtime
can disable the VDDA supply. This creates some conditions on I/Os that
can start to leak current.
So PCSEL needs to be cleared when disabling the ADC.

commit 67fe29583e72b2103abb661bb58036e3c1f00277 upstream.
IIO trigger handlers must call iio_trigger_notify_done() when done. This
must be done even when an error occurred. Otherwise the trigger will be
seen as busy indefinitely and the trigger handler will never be called
again.
The itg3200 driver neglects to call iio_trigger_notify_done() when there is
an error reading the gyro data. Fix this by making sure that
iio_trigger_notify_done() is included in the error exit path.

commit cd0082235783f814241a1c9483fb89e405f4f892 upstream.
The mma8452 driver directly assigns a trigger to the struct iio_dev. The
IIO core when done using this trigger will call `iio_trigger_put()` to drop
the reference count by 1.
Without the matching `iio_trigger_get()` in the driver the reference count
can reach 0 too early, the trigger gets freed while still in use and a
use-after-free occurs.
Fix this by getting a reference to the trigger before assigning it to the
IIO device.

commit a827a4984664308f13599a0b26c77018176d0c7c upstream.
In viio_trigger_alloc() device_initialize() is used to set the initial
reference count of the trigger to 1. Then another get_device() is called on
trigger. This sets the reference count to 2 before the trigger is returned.
iio_trigger_free(), which is the matching API to viio_trigger_alloc(),
calls put_device() which decreases the reference count by 1. But the second
reference count acquired in viio_trigger_alloc() is never dropped.
As a result the iio_trigger_release() function is never called and the
memory associated with the trigger is never freed.
Since there is no reason for the trigger to start its lifetime with two
reference counts just remove the extra get_device() in
viio_trigger_alloc().

commit 7faac1953ed1f658f719cdf7bb7303fa5eef822c upstream.
Make xhci_disable_slot() synchronous, thus ensuring it, and
xhci_free_dev() calling it return after xHC controller completes
the disable slot command.
Otherwise the roothub and xHC host may runtime suspend, and clear the
command ring while the disable slot command is being processed.
This causes a command completion mismatch as the completion event can't
be mapped to the correct command.
Command ring gets out of sync and commands time out.
Driver finally assumes host is unresponsive and bails out.

commit 811ae81320da53a5670c36970cefacca8519f90e upstream.
When the xHCI is quirked with XHCI_RESET_ON_RESUME, runtime resume
routine also resets the controller.
This is bad for USB drivers without reset_resume callback, because
there's no subsequent call of usb_dev_complete() ->
usb_resume_complete() to force rebinding the driver to the device. For
instance, btusb device stops working after xHCI controller is runtime
resumed, if the controlled is quirked with XHCI_RESET_ON_RESUME.
So always take XHCI_RESET_ON_RESUME into account to solve the issue.

commit f6071e5e3961eeb5300bd0901c9e128598730ae3 upstream.
Currently rp_filter tests in fib_tests.sh:fib_rp_filter_test() are
failing. ping sockets are bound to dummy1 using the "-I" option
(SO_BINDTODEVICE), but socket lookup is failing when receiving ping
replies, since the routing table thinks they belong to dummy0.
For example, suppose ping is using a SOCK_RAW socket for ICMP messages.
When receiving ping replies, in __raw_v4_lookup(), sk->sk_bound_dev_if
is 3 (dummy1), but dif (skb_rtable(skb)->rt_iif) says 2 (dummy0), so the
raw_sk_bound_dev_eq() check fails. Similar things happen in
ping_lookup() for SOCK_DGRAM sockets.
These tests used to pass due to a bug [1] in iputils, where "ping -I"
actually did not bind ICMP message sockets to device. The bug has been
fixed by iputils commit f455fee41c07 ("ping: also bind the ICMP socket
to the specific device") in 2016, which is why our rp_filter tests
started to fail. See [2] .
Fixing the tests while keeping everything in one netns turns out to be
nontrivial. Rework the tests and build the following topology:
┌─────────────────────────────┐ ┌─────────────────────────────┐
│ network namespace 1 (ns1) │ │ network namespace 2 (ns2) │
│ │ │ │
│ ┌────┐ ┌─────┐ │ │ ┌─────┐ ┌────┐ │
│ │ lo │<───>│veth1│<────────┼────┼─>│veth2│<──────────>│ lo │ │
│ └────┘ ├─────┴──────┐ │ │ ├─────┴──────┐ └────┘ │
│ │192.0.2.1/24│ │ │ │192.0.2.1/24│ │
│ └────────────┘ │ │ └────────────┘ │
└─────────────────────────────┘ └─────────────────────────────┘
Consider sending an ICMP_ECHO packet A in ns2. Both source and
destination IP addresses are 192.0.2.1, and we use strict mode rp_filter
in both ns1 and ns2:
1. A is routed to lo since its destination IP address is one of ns2's
local addresses (veth2);
2. A is redirected from lo's egress to veth2's egress using mirred;
3. A arrives at veth1's ingress in ns1;
4. A is redirected from veth1's ingress to lo's ingress, again, using
mirred;
5. In __fib_validate_source(), fib_info_nh_uses_dev() returns false,
since A was received on lo, but reverse path lookup says veth1;
6. However A is not dropped since we have relaxed this check for lo in
commit 66f8209547cc ("fib: relax source validation check for loopback
packets");
Making sure A is not dropped here in this corner case is the whole point
of having this test.
7. As A reaches the ICMP layer, an ICMP_ECHOREPLY packet, B, is
generated;
8. Similarly, B is redirected from lo's egress to veth1's egress (in
ns1), then redirected once again from veth2's ingress to lo's
ingress (in ns2), using mirred.
Also test "ping 127.0.0.1" from ns2. It does not trigger the relaxed
check in __fib_validate_source(), but just to make sure the topology
works with loopback addresses.
