be50365391 net: mctp: copy skb ext data when fragmenting
[ Upstream commit 1394c1dec1c619a46867ed32791a29695372bff8 ]

If we're fragmenting on local output, the original packet may contain
ext data for the MCTP flows. We'll want this in the resulting fragment
skbs too.

So, do a skb_ext_copy() in the fragmentation path, and implement the
MCTP-specific parts of an ext copy operation.

All Ethernet AVB instances on R-Car V4H have registers related to UDP/IP

are too small to cover them.

Fix this by extending the register block sizes.

f1773a106c memory: tegra: Correct DLA client names
[ Upstream commit 51d915cbeef4c7a154f5d810b1e10d8125f2b0cc ]

Some of the names for the Tegra234 DLA clients are not unique and do not
align with the name of the client ID definitions. Therefore, it is not
possible to determine the exact DLA client from messages that print the
client name. Fix this by correcting the DLA memory client names for
Tegra234 to align with the name of the corresponding memory client ID.

Note that although the client names are also used by the interconnect
framework, interconnect support for the DLA clients has not been added
and so this issue does not impact the interconnect support.

[ Upstream commit 3baa4c5143d65ebab2de0d99a395e5f4f1f46608 ]

When the development chip ROM was added, the "direct-mapped" compatible
value was already obsolete.  In addition, the device node lacked the
accompanying "probe-type" property, causing the old physmap_of_core
driver to fall back to trying all available probe types.
Unfortunately this fallback was lost when the DT and pdata cases were
merged.

Fix this by using the modern "mtd-rom" compatible value instead.

0f7bdcbb0f wifi: wilc1000: revert reset line logic flip
[ Upstream commit f3ec643947634bed41b97bd56b248f7c78498eab ]

This reverts commit fcf690b0b47494df51d214db5c5a714a400b0257.

When using a wilc1000 chip over a spi bus, users can optionally define a
reset gpio and a chip enable gpio. The reset line of wilc1000 is active
low, so to hold the chip in reset, a low (physical) value must be applied.

The corresponding device tree binding documentation was introduced by
commit f31ee3c0a555 ("wilc1000: Document enable-gpios and reset-gpios
properties") and correctly indicates that the reset line is an active-low
signal. The corresponding driver part, brought by commit ec031ac4792c
("wilc1000: Add reset/enable GPIO support to SPI driver") was applying the
correct logic. But commit fcf690b0b474 ("wifi: wilc1000: use correct
sequence of RESET for chip Power-UP/Down") eventually flipped this logic
and started misusing the gpiod APIs, applying an inverted logic when
powering up/down the chip (for example, setting the reset line to a logic
"1" during power up, which in fact asserts the reset line when device tree
describes the reset line as GPIO_ACTIVE_LOW). As a consequence, any
platform currently using the driver in SPI mode must use a faulty reset
line description in device tree, or else chip will be maintained in reset
and will not even allow to bring up the chip.

Fix reset line usage by inverting back the gpiod APIs usage, setting the
reset line to the logic value "0" when powering the chip, and the logic
value "1" when powering off the chip.

[ Upstream commit f1d71576d2c9ec8fdb822173fa7f3de79475e9bd ]

When the generic SCMI code tears down a channel, it calls the chan_free
callback function, defined by each transport. Since multiple protocols
might share the same transport_info member, chan_free() might want to
clean up the same member multiple times within the given SCMI transport
implementation. In this case, it is SMC transport. This will lead to a NULL
pointer dereference at the second time:

Simply check for the struct pointer being NULL before trying to access
its members, to avoid this situation.

This was found when a transport doesn't really work (for instance no SMC
service), the probe routines then tries to clean up, and triggers a crash.

The external output reset signal was originally disabled and sent from
firmware. However, an unfixed bug in the firmware on tomato prevents
the signal from being sent, causing the device to fail to boot. To fix
this, enable external output reset signal to allow the device to reboot

3438dccde5 iommu/amd: Mark interrupt as managed
[ Upstream commit 0feda94c868d396fac3b3cb14089d2d989a07c72 ]

On many systems that have an AMD IOMMU the following sequence of
warnings is observed during bootup.

```
pci 0000:00:00.2  can't derive routing for PCI INT A
pci 0000:00:00.2: PCI INT A: not connected
```

This series of events happens because of the IOMMU initialization
sequence order and the lack of _PRT entries for the IOMMU.

During initialization the IOMMU driver first enables the PCI device
using pci_enable_device().  This will call acpi_pci_irq_enable()
which will check if the interrupt is declared in a PCI routing table
(_PRT) entry. According to the PCI spec [1] these routing entries
are only required under PCI root bridges:
	The _PRT object is required under all PCI root bridges

The IOMMU is directly connected to the root complex, so there is no
parent bridge to look for a _PRT entry. The first warning is emitted
since no entry could be found in the hierarchy. The second warning is
then emitted because the interrupt hasn't yet been configured to any
value.  The pin was configured in pci_read_irq() but the byte in
PCI_INTERRUPT_LINE return 0xff which means "Unknown".

After that sequence of events pci_enable_msi() is called and this
will allocate an interrupt.

That is both of these warnings are totally harmless because the IOMMU
uses MSI for interrupts.  To avoid even trying to probe for a _PRT
entry mark the IOMMU as IRQ managed. This avoids both warnings.

wilc_netdev_cleanup currently triggers a KASAN warning, which can be
observed on interface registration error path, or simply by
removing the module/unbinding device from driver:

David Mosberger-Tan initial investigation [1] showed that this
use-after-free is due to netdevice unregistration during vif list
traversal. When unregistering a net device, since the needs_free_netdev has
been set to true during registration, the netdevice object is also freed,
and as a consequence, the corresponding vif object too, since it is
attached to it as private netdevice data. The next occurrence of the loop
then tries to access freed vif pointer to the list to move forward in the
list.

Fix this use-after-free thanks to two mechanisms:
- navigate in the list with list_for_each_entry_safe, which allows to
  safely modify the list as we go through each element. For each element,
  remove it from the list with list_del_rcu
- make sure to wait for RCU grace period end after each vif removal to make
  sure it is safe to free the corresponding vif too (through
  unregister_netdev)

Since we are in a RCU "modifier" path (not a "reader" path), and because
such path is expected not to be concurrent to any other modifier (we are
using the vif_mutex lock), we do not need to use RCU list API, that's why
we can benefit from list_for_each_entry_safe.

af35d0639a cpufreq: qcom-hw: add CONFIG_COMMON_CLK dependency
[ Upstream commit 3093fa33539b54db77171d2919352ad4f044a1c5 ]

It is still possible to compile-test a kernel without CONFIG_COMMON_CLK
for some ancient ARM boards or other architectures, but this causes a
link failure in the qcom-cpufreq-hw driver:

ERROR: modpost: "devm_clk_hw_register" [drivers/cpufreq/qcom-cpufreq-hw.ko] undefined!
ERROR: modpost: "devm_of_clk_add_hw_provider" [drivers/cpufreq/qcom-cpufreq-hw.ko] undefined!
ERROR: modpost: "of_clk_hw_onecell_get" [drivers/cpufreq/qcom-cpufreq-hw.ko] undefined!

Add a Kconfig dependency here to make sure this always work. Apparently
this bug has been in the kernel for a while without me running into it
on randconfig builds as COMMON_CLK is almost always enabled.

I have cross-checked by building an allmodconfig kernel with COMMON_CLK
disabled, which showed no other driver having this problem.

cfdca1154f arm64: dts: mediatek: mt8186: Add missing xhci clock to usb controllers
[ Upstream commit 1af98c3e53da5a8f627855cecd68b017e753ffd3 ]

The mtu3 usb controllers don't list the xhci clock, though they require
it, and thus rely on the bootloader leaving it on in order to work.

When booting with the upstream arm64 defconfig, the usb controllers will
defer probe until modules have loaded since they have an indirect
dependency on CONFIG_MTK_CMDQ, which is configured as a module. However
at the point where modules are loaded, unused clocks are also disabled,
causing the usb controllers to probe without the xhci clock enabled and
fail to probe:

mtu3 11201000.usb: clks of sts1 are not stable!
mtu3 11201000.usb: device enable failed -110
mtu3 11201000.usb: mtu3 hw init failed:-110
mtu3 11201000.usb: failed to initialize gadget
mtu3: probe of 11201000.usb failed with error -110

(and same for the one at 11281000)

Add the missing clock for the usb controllers so that they can
successfully probe without relying on the bootloader state.

[ Upstream commit a00d4a98af44e025891e97c490b2545368a25e08 ]

The ssusb power domains currently don't list any clocks, despite
depending on some, and thus rely on the bootloader leaving the required
clocks on in order to work.

When booting with the upstream arm64 defconfig, the power domain
controller will defer probe until modules have loaded since it has an
indirect dependency on CONFIG_MTK_CMDQ, which is configured as a module.
However at the point where modules are loaded, unused clocks are also
disabled, causing the ssusb domains to fail to be enabled and
consequently the controller to fail probe:

mtk-power-controller: probe of 10006000.syscon:power-controller failed with error -110

Add the missing clocks for the ssusb power domains so that they can
successfully probe without relying on the bootloader state.

Note that the non-ECC-corrected qfprom can be found at 0xfc4b8000

e36373dc5e bpf: Mark bpf_spin_{lock,unlock}() helpers with notrace correctly
[ Upstream commit 178c54666f9c4d2f49f2ea661d0c11b52f0ed190 ]

Currently tracing is supposed not to allow for bpf_spin_{lock,unlock}()
helper calls. This is to prevent deadlock for the following cases:
  - there is a prog (prog-A) calling bpf_spin_{lock,unlock}().
  - there is a tracing program (prog-B), e.g., fentry, attached
    to bpf_spin_lock() and/or bpf_spin_unlock().
  - prog-B calls bpf_spin_{lock,unlock}().
For such a case, when prog-A calls bpf_spin_{lock,unlock}(),
a deadlock will happen.

The related source codes are below in kernel/bpf/helpers.c:
  notrace BPF_CALL_1(bpf_spin_lock, struct bpf_spin_lock *, lock)
  notrace BPF_CALL_1(bpf_spin_unlock, struct bpf_spin_lock *, lock)
notrace is supposed to prevent fentry prog from attaching to
bpf_spin_{lock,unlock}().

But actually this is not the case and fentry prog can successfully
attached to bpf_spin_lock(). Siddharth Chintamaneni reported
the issue in [1]. The following is the macro definition for
above BPF_CALL_1:
  #define BPF_CALL_x(x, name, ...)                                               \
        static __always_inline                                                 \
        u64 ____##name(__BPF_MAP(x, __BPF_DECL_ARGS, __BPF_V, __VA_ARGS__));   \
        typedef u64 (*btf_##name)(__BPF_MAP(x, __BPF_DECL_ARGS, __BPF_V, __VA_ARGS__)); \
        u64 name(__BPF_REG(x, __BPF_DECL_REGS, __BPF_N, __VA_ARGS__));         \
        u64 name(__BPF_REG(x, __BPF_DECL_REGS, __BPF_N, __VA_ARGS__))          \
        {                                                                      \
                return ((btf_##name)____##name)(__BPF_MAP(x,__BPF_CAST,__BPF_N,__VA_ARGS__));\
        }                                                                      \
        static __always_inline                                                 \
        u64 ____##name(__BPF_MAP(x, __BPF_DECL_ARGS, __BPF_V, __VA_ARGS__))

  #define BPF_CALL_1(name, ...)   BPF_CALL_x(1, name, __VA_ARGS__)

The notrace attribute is actually applied to the static always_inline function
____bpf_spin_{lock,unlock}(). The actual callback function
bpf_spin_{lock,unlock}() is not marked with notrace, hence
allowing fentry prog to attach to two helpers, and this
may cause the above mentioned deadlock. Siddharth Chintamaneni
actually has a reproducer in [2].

To fix the issue, a new macro NOTRACE_BPF_CALL_1 is introduced which
will add notrace attribute to the original function instead of
the hidden always_inline function and this fixed the problem.
