[ Upstream commit 79978bff2e4b8e05ebdf5fc3ee6b794002393484 ]
We identified that the PHYs actually do not work since commit 7da7b84fee58
("ARM: dts: imx6dl-yapp4: Move phy reset into switch node") as
a coincidence of several circumstances.
The reset signal is kept asserted by a pull-down resistor on the board
unless it is deasserted by GPIO from the SoC. This is to keep the switch
dead until it is configured properly by the kernel and user space.
Prior to the referenced commit the switch was reset by the FEC driver
and the reset GPIO was actively deasserted. The mdio-bus was scanned
and the attached switch and its PHYs were found and configured.
With the referenced commit the switch is reset by the qca8k driver.
Because of another bug in the qca8k driver, functionality of the reset
pin depends on its pre-kernel configuration. See commit c44fc98f0a8f
("net: dsa: qca8k: fix illegal usage of GPIO")
The problem did not appear until we removed support for the switch
and configuration of its reset pin from the bootloader.
To fix that, properly describe the internal mdio-bus configuration of
the qca8334 switch. The PHYs are internal to the switch and sit on its
internal mdio-bus.

This change does not have any functional effect. The switch works just
fine without this patch as it has full access to all the addresses

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

Unfortunately this fallback was lost when the DT and pdata cases were
merged.
Fix this by using the modern "mtd-rom" compatible value instead.

[ 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.

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.

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.

The cbas node is used to describe base detection functionality in the
ChromeOS EC, which is used for units that have a detachable keyboard and
thus rely on this functionality to switch between tablet and laptop
mode.
Despite the original commit having added the cbas node to the
mt8183-kukui.dtsi, not all machines that include it are detachables. In
fact all machines that include from mt8183-kukui-jacuzzi.dtsi are either
clamshells (ie normal laptops) or convertibles, meaning the keyboard can
be flipped but not detached. The detection for the keyboard getting
flipped is handled by the driver bound to the keyboard-controller node
in the EC.
Move the base detection node from the base kukui dtsi to the dtsis where
all machines are detachables, and thus actually make use of the node.

in igmp6_event_query() and igmp6_event_report()")) I think the
synchronize_net() call in ipv6_mc_down() is not needed.
Under load, synchronize_net() can last between 200 usec and 5 ms.
KASAN seems to agree as well.

'-fPIC' as an option to the linker does not do what it seems like it
should. With ld.bfd, it is treated as '-f PIC', which does not make
sense based on the meaning of '-f':
-f SHLIB, --auxiliary SHLIB Auxiliary filter for shared object symbol table
When building with ld.lld (currently under review in a GitHub pull
request), it just errors out because '-f' means nothing and neither does
'-fPIC':
ld.lld: error: unknown argument '-fPIC'
'-fPIC' was blindly copied from CFLAGS when the vDSO stopped being
linked with '$(CC)', it should not be needed. Remove it to clear up the

The firmware (later) actually uses the values even for keys
that are invalid as far as the host is concerned, later in
rekeying, and then only sets the low 48 bits since the PNs
are only 48 bits over the air. It does, however, compare the
full 64 bits later, obviously causing problems.
Remove the memset and use kzalloc instead to avoid any old
heap data leaking to the firmware. We already init all the
other fields in the struct anyway. This leaves the data set
to zero for any unused fields, so the firmware can look at
them safely even if they're not used right now.

The driver only used the number of pwm channels to set the pwm_chip's
npwm member. The result is that if there are more capture channels than
PWM channels specified in the device tree, only a part of the capture

many driver authors wrongly assume it's possible to do error handling by

The ath9k_wmi_event_tasklet() used in ath9k_htc assumes that all the data
structures have been fully initialised by the time it runs. However, because of
the order in which things are initialised, this is not guaranteed to be the
case, because the device is exposed to the USB subsystem before the ath9k driver
initialisation is completed.
We already committed a partial fix for this in commit:
8b3046abc99e ("ath9k_htc: fix NULL pointer dereference at ath9k_htc_tx_get_packet()")
However, that commit only aborted the WMI_TXSTATUS_EVENTID command in the event
tasklet, pairing it with an "initialisation complete" bit in the TX struct. It
seems syzbot managed to trigger the race for one of the other commands as well,
so let's just move the existing synchronisation bit to cover the whole
tasklet (setting it at the end of ath9k_htc_probe_device() instead of inside
ath9k_tx_init()).

Instead we can do it like other boards already do and simply mux the

the correct voltage is selected by setting the PMIC's SD_VSEL input
