The START_TRANSFER command needs to be executed while in ON/U0 link
state (with an exception during register initialization). Don't use
dwc->link_state to check this since the driver only tracks the link
state when the link state change interrupt is enabled. Check the link
state from DSTS register instead.
Note that often the host already brings the device out of low power
before it sends/requests the next transfer. So, the user won't see any
issue when the device starts transfer then. This issue is more
noticeable in cases when the device delays starting transfer, which can
happen during delayed control status after the host put the device in
low power.

commit 1fe976d308 upstream.
Since commit fee2d54641 ("net: phy: marvell: mv88e6390 temperature
sensor reading"), Linux reports the temperature of Topaz hwmon as
constant -75°C.
This is because switches from the Topaz family (88E6141 / 88E6341) have
the address of the temperature sensor register different from Peridot.
This address is instead compatible with 88E1510 PHYs, as was used for
Topaz before the above mentioned commit.
Create a new mapping table between switch family and PHY ID for families
which don't have a model number. And define PHY IDs for Topaz and Peridot
families.
Create a new PHY ID and a new PHY driver for Topaz's internal PHY.
The only difference from Peridot's PHY driver is the HWMON probing
method.
Prior this change Topaz's internal PHY is detected by kernel as:
PHY [...] driver [Marvell 88E6390] (irq=63)
And afterwards as:
PHY [...] driver [Marvell 88E6341 Family] (irq=63)

commit d2f7eca60b upstream.
Since uprobes is not supported for thumb, check that the thumb bit is
not set when matching the uprobes instruction hooks.
The Arm UDF instructions used for uprobes triggering
(UPROBE_SWBP_ARM_INSN and UPROBE_SS_ARM_INSN) coincidentally share the
same encoding as a pair of unallocated 32-bit thumb instructions (not
UDF) when the condition code is 0b1111 (0xf). This in effect makes it
possible to trigger the uprobes functionality from thumb, and at that
using two unallocated instructions which are not permanently undefined.

[ Upstream commit 24c109bb15 ]
The mixed signed bounds check really belongs into retrieve_ptr_limit()
instead of outside of it in adjust_ptr_min_max_vals(). The reason is
that this check is not tied to PTR_TO_MAP_VALUE only, but to all pointer
types that we handle in retrieve_ptr_limit() and given errors from the latter
propagate back to adjust_ptr_min_max_vals() and lead to rejection of the
program, it's a better place to reside to avoid anything slipping through
for future types. The reason why we must reject such off_reg is that we
otherwise would not be able to derive a mask, see details in 9d7eceede7

__vmx_handle_exit() uses vcpu->run->internal.ndata as an index for

space with a writer permission, the 'ndata' could be updated by the
user process at anytime (the user process can set it to outside the

So, it is not safe that __vmx_handle_exit() uses the 'ndata' that way.

[ Upstream commit 8e53324021 ]
Convert vcpu_vmx.exit_reason from a u32 to a union (of size u32). The
full VM_EXIT_REASON field is comprised of a 16-bit basic exit reason in
bits 15:0, and single-bit modifiers in bits 31:16.
Historically, KVM has only had to worry about handling the "failed
VM-Entry" modifier, which could only be set in very specific flows and
required dedicated handling. I.e. manually stripping the FAILED_VMENTRY
bit was a somewhat viable approach. But even with only a single bit to
worry about, KVM has had several bugs related to comparing a basic exit
reason against the full exit reason store in vcpu_vmx.
Upcoming Intel features, e.g. SGX, will add new modifier bits that can
be set on more or less any VM-Exit, as opposed to the significantly more
restricted FAILED_VMENTRY, i.e. correctly handling everything in one-off
flows isn't scalable. Tracking exit reason in a union forces code to
explicitly choose between consuming the full exit reason and the basic
exit, and is a convenient way to document and access the modifiers.
No functional change intended.

which has an active-high switch, while the Pine64-LTS use the more

commit 38ec4944b5 upstream.
After commit 0f6925b3e8 ("virtio_net: Do not pull payload in skb->head")
Guenter Roeck reported one failure in his tests using sh architecture.
After much debugging, we have been able to spot silent unaligned accesses
in inet_gro_receive()
The issue at hand is that upper networking stacks assume their header
is word-aligned. Low level drivers are supposed to reserve NET_IP_ALIGN
bytes before the Ethernet header to make that happen.
This patch hardens skb_gro_reset_offset() to not allow frag0 fast-path
if the fragment is not properly aligned.
Some arches like x86, arm64 and powerpc do not care and define NET_IP_ALIGN
as 0, this extra check will be a NOP for them.
Note that if frag0 is not used, GRO will call pskb_may_pull()
as many times as needed to pull network and transport headers.

commit e8a4155567 upstream.
snd_una update should not be done when the same skb is being
sent out.chcr_short_record_handler() sends it again even
though SND_UNA update is already sent for the skb in
chcr_ktls_xmit(), which causes mismatch in un-acked
TCP seq number, later causes problem in sending out
complete record.

commit bc16efd243 upstream.
When sge queue is full and chcr_ktls_xmit_wr_complete()
returns failure, skb is not freed if it is not the last tls record in
this skb, causes refcount never gets freed and tls_dev_del()
never gets called on this connection.
