vmxnet3_get_rss()
The value adapter->rss_conf is stored in DMA memory, and it is assigned
to rssConf, so rssConf->indTableSize can be modified at anytime by
malicious hardware. Because rssConf->indTableSize is assigned to n,
buffer overflow may occur when the code "rssConf->indTable[n]" is
executed.
To fix this possible bug, n is checked after being used.

Microchip lan7431 is frequently connected to a phy. However, it
can also be directly connected to a MII remote peer without
any phy in between. For supporting such a phyless hardware setup
in Linux we utilized phylib, which supports a fixed-link
configuration via the device tree. And we added support for
defining the connection type R/GMII in the device tree.
New behavior:
-------------
. The automatic speed and duplex detection of the lan743x silicon
between mac and phy is disabled. Instead phylib is used like in
other typical Linux drivers. The usage of phylib allows to
specify fixed-link parameters in the device tree.
. The device tree entry phy-connection-type is supported now with
the modes RGMII or (G)MII (default).
Development state:
------------------
. Tested with fixed-phy configurations. Not yet tested in normal
configurations with phy. Microchip kindly offered testing
as soon as the Corona measures allow this.
. All review findings of Andrew Lunn are included
Example:
--------
&pcie {
status = "okay";
host@0 {
reg = <0 0 0 0 0>;
#address-cells = <3>;
#size-cells = <2>;
ethernet@0 {
compatible = "weyland-yutani,noscom1", "microchip,lan743x";
status = "okay";
reg = <0 0 0 0 0>;
phy-connection-type = "rgmii";
fixed-link {
speed = <100>;
full-duplex;
};
};
};
};

We currently have an Rx listener function for exception traps that marks
received skbs with 'offload_fwd_mark' and injects them to the kernel's
Rx path. The marking is done because all these exceptions occur during
L3 forwarding, after the packets were potentially flooded at L2.
A subsequent patch will add support for control traps. Packets received
via some of these control traps need different handling:
1. Packets might not need to be marked with 'offload_fwd_mark'. For
example, if packet was trapped before L2 forwarding
2. Packets might not need to be injected to the kernel's Rx path. For
example, sampled packets are reported to user space via the psample
module
Factor out a common Rx listener function that only reports trapped
packets to devlink. Call it from mlxsw_sp_rx_no_mark_listener() and
mlxsw_sp_rx_mark_listener() that will inject the packets to the kernel's
Rx path, without and with the marking, respectively.

Register two control traps with devlink. The existing selftest at
tools/testing/selftests/drivers/net/netdevsim/devlink_trap.sh iterates
over all registered traps and checks that the action of non-drop traps
cannot be changed. Up until now only exception traps were tested, now
control traps will be tested as well.

The removal of mips_swiotlb_ops exposed a problem in octeon_mgmt Ethernet
driver. mips_swiotlb_ops had an mb() after most of the operations and the
removal of the ops had broken the receive functionality of the driver.
My code inspection has shown no other places except
octeon_mgmt_rx_fill_ring() where an explicit barrier would be obviously
missing. The latter function however has to make sure that "ringing the
bell" doesn't happen before RX ring entry is really written.
The patch has been successfully tested on Octeon II.

When proxy mode is enabled the vxlan device might reply to Neighbor
Solicitation (NS) messages on behalf of remote hosts.
In case the NS message includes the "Source link-layer address" option
[1], the vxlan device will use the specified address as the link-layer
destination address in its reply.
To avoid an infinite loop, break out of the options parsing loop when
encountering an option with length zero and disregard the NS message.
This is consistent with the IPv6 ndisc code and RFC 4886 which states
that "Nodes MUST silently discard an ND packet that contains an option
with length zero" [2].

Commit c100beb9ccfb ("PCI/AER: Use only _OSC to determine AER ownership")
removed the use of HEST in determining AER ownership, but the AER driver
still used HEST to verify AER ownership in some of its APIs.
Per the ACPI spec v6.3, sec 18.3.2.4, some HEST table entries contain a
FIRMWARE_FIRST bit, but that bit does not tell us anything about ownership
of the AER capability.
Remove parsing of HEST to look for FIRMWARE_FIRST.
Add pcie_aer_is_native() for the places that need to know whether the OS
owns the AER capability.

working due to the ASUS WMI driver fails to be loaded. The ACPI error
as follows leads to the failure of asus_wmi_evaluate_method.
ACPI BIOS Error (bug): AE_AML_BUFFER_LIMIT, Field [IIA3] at bit offset/length 96/32 exceeds size of target Buffer (96 bits) (20200326/dsopcode-203)
No Local Variables are initialized for Method [WMNB]
ACPI Error: Aborting method \_SB.ATKD.WMNB due to previous error (AE_AML_BUFFER_LIMIT) (20200326/psparse-531)
The DSDT for the WMNB part shows that 5 DWORD required for local
variables and the 3rd variable IIA3 hit the buffer limit.
Method (WMNB, 3, Serialized)
{ ..
CreateDWordField (Arg2, Zero, IIA0)
CreateDWordField (Arg2, 0x04, IIA1)
CreateDWordField (Arg2, 0x08, IIA2)
CreateDWordField (Arg2, 0x0C, IIA3)
CreateDWordField (Arg2, 0x10, IIA4)
Local0 = (Arg1 & 0xFFFFFFFF)
If ((Local0 == 0x54494E49))
..
}
The limitation is determined by the input acpi_buffer size passed
to the wmi_evaluate_method. Since the struct bios_args is the data
structure used as input buffer by default for all ASUS WMI calls,
the size needs to be expanded to fix the problem.

chasis-type
The HP Stream x360 11-p000nd no longer report SW_TABLET_MODE state / events
with recent kernels. This model reports a chassis-type of 10 / "Notebook"
which is not on the recently introduced chassis-type whitelist
Commit de9647efeaa9 ("platform/x86: intel-vbtn: Only activate tablet mode
switch on 2-in-1's") added a chassis-type whitelist and only listed 31 /
"Convertible" as being capable of generating valid SW_TABLET_MOD events.
Commit 1fac39fd0316 ("platform/x86: intel-vbtn: Also handle tablet-mode
switch on "Detachable" and "Portable" chassis-types") extended the
whitelist with chassis-types 8 / "Portable" and 32 / "Detachable".
And now we need to exten the whitelist again with 10 / "Notebook"...
The issue original fixed by the whitelist is really a ACPI DSDT bug on
the Dell XPS 9360 where it has a VGBS which reports it is in tablet mode
even though it is not a 2-in-1 at all, but a regular laptop.
So since this is a workaround for a DSDT issue on that specific model,
instead of extending the whitelist over and over again, lets switch to
a blacklist and only blacklist the chassis-type of the model for which
the chassis-type check was added.
Note this also fixes the current version of the code no longer checking
if dmi_get_system_info(DMI_CHASSIS_TYPE) returns NULL.

HEBC method reports capabilities of 5 button array but HP Spectre X2 (2015)
does not have this control method (the same was for Wacom MobileStudio Pro).
Expand previous DMI quirk by Alex Hung to also enable 5 button array
for this system.

pm_runtime_get_sync() increments the runtime PM usage counter even
when it returns an error code. Thus a pairing decrement is needed on
the error handling path to keep the counter balanced.
Also, call pm_runtime_disable() when pm_runtime_get_sync() returns
an error code.

non-MIPS platforms
This commit:
818e915fbac5: ("irqchip: Add Loongson HyperTransport Vector support")
Added a MIPS-only driver, but turned on compilation on all other architectures as well:
config LOONGSON_HTVEC
bool "Loongson3 HyperTransport Interrupt Vector Controller"
depends on MACH_LOONGSON64 || COMPILE_TEST
But this driver was never build tested on any other architecture than MIPS:
drivers/irqchip/irq-loongson-htvec.c: In function ‘htvec_irq_dispatch’:
drivers/irqchip/irq-loongson-htvec.c:59:3: error: implicit declaration of function ‘spurious_interrupt’; did you mean ‘smp_reboot_interrupt’? [-Werror=implicit-function-declaration]
Because spurious_interrupt() only exists on MIPS.
So make it MIPS-only.
