[ Upstream commit 7a601e2cf61558dfd534a9ecaad09f5853ad8204 ]
Enlightened VMCS v1 doesn't have VMX_PREEMPTION_TIMER_VALUE field,
PIN_BASED_VMX_PREEMPTION_TIMER is also filtered out already so it makes
sense to filter out VM_EXIT_SAVE_VMX_PREEMPTION_TIMER too.
Note, none of the currently existing Windows/Hyper-V versions are known
to enable 'save VMX-preemption timer value' when eVMCS is in use, the
change is aimed at making the filtering future proof.

When setting up autonegotiation for 88E1118R and compatible PHYs,
a software reset of PHY is issued before setting up polarity.
This is incorrect as changes of MDI Crossover Mode bits are
disruptive to the normal operation and must be followed by a

commit fe4f57bf7b585dca58f1496c4e2481ecbae18126 upstream.
It is mandatory for a software to issue a reset upon modifying RGMII
Receive Timing Control and RGMII Transmit Timing Control bit fields of MAC
Specific Control register 2 (page 2, register 21) otherwise the changes
won't be perceived by the PHY (the same is applicable for a lot of other
registers). Not setting the RGMII delays on the platforms that imply it'
being done on the PHY side will consequently cause the traffic loss. We
discovered that the denoted soft-reset is missing in the
m88e1121_config_aneg() method for the case if the RGMII delays are
modified but the MDIx polarity isn't changed or the auto-negotiation is
left enabled, thus causing the traffic loss on our platform with Marvell
Alaska 88E1510 installed. Let's fix that by issuing the soft-reset if the
delays have been actually set in the m88e1121_config_aneg_rgmii_delays()
method.

Commit c2426d2ad5027 ("ima: added support for new kernel cmdline parameter
ima_template_fmt") introduced an additional check on the ima_template
variable to avoid multiple template selection.
Unfortunately, ima_template could be also set by the setup function of the
ima_hash= parameter, when it calls ima_template_desc_current(). This causes
attempts to choose a new template with ima_template= or with
ima_template_fmt=, after ima_hash=, to be ignored.
Achieve the goal of the commit mentioned with the new static variable
template_setup_done, so that template selection requests after ima_hash=
are not ignored.
Finally, call ima_init_template_list(), if not already done, to initialize
the list of templates before lookup_template_desc() is called.

commit 9aa422ad326634b76309e8ff342c246800621216 upstream.
The function tipc_mon_rcv() allows a node to receive and process
domain_record structs from peer nodes to track their views of the
network topology.
This patch verifies that the number of members in a received domain
record does not exceed the limit defined by MAX_MON_DOMAIN, something
that may otherwise lead to a stack overflow.
tipc_mon_rcv() is called from the function tipc_link_proto_rcv(), where
we are reading a 32 bit message data length field into a uint16. To
avert any risk of bit overflow, we add an extra sanity check for this in
that function. We cannot see that happen with the current code, but
future designers being unaware of this risk, may introduce it by
allowing delivery of very large (> 64k) sk buffers from the bearer
layer. This potential problem was identified by Eric Dumazet.

commit 5297c693d8c8e08fa742e3112cf70723f7a04da2 upstream.
After commit 266423e60ea1 ("pinctrl: bcm2835: Change init order for gpio
hogs") a few error paths would not unwind properly the registration of
gpio ranges. Correct that by assigning a single error label and goto it
whenever we encounter a fatal error.

Check for negative values of "priv->gain" to prevent an out of bounds
access. The concern is that these might come from the user via:
-> snd_ctl_elem_write_user()
-> snd_ctl_elem_write()
-> kctl->put()

commit f7a6021aaf02088870559f82fc13c58cda7fea1a upstream.
If the device does not exist, of_get_child_by_name() will return NULL
pointer.
And devm_snd_soc_register_component() does not check it.
Also, I have noticed that cpcap_codec_driver has not been used yet.
Therefore, it should be better to check it in order to avoid the future
dereference of the NULL pointer.

commit e958b5884725dac86d36c1e7afe5a55f31feb0b2 upstream.
This patch is based on one in the Xilinx kernel tree, "ASoc: xlnx: Make
buffer bytes multiple of period bytes" by Devarsh Thakkar. The same
issue exists in the mainline version of the driver. The original
patch description is as follows:
"The Xilinx Audio Formatter IP has a constraint on period
bytes to be multiple of 64. This leads to driver changing
the period size to suitable frames such that period bytes
are multiple of 64.
Now since period bytes and period size are updated but not
the buffer bytes, this may make the buffer bytes unaligned
and not multiple of period bytes.
When this happens we hear popping noise as while DMA is being
done the buffer bytes are not enough to complete DMA access
for last period of frame within the application buffer boundary.
To avoid this, align buffer bytes too as multiple of 64, and
set another constraint to always enforce number of periods as
integer. Now since, there is already a rule in alsa core
to enforce Buffer size = Number of Periods * Period Size
this automatically aligns buffer bytes as multiple of period
bytes."

Even if protected from preemption and interrupts, a small time window
remains when the 2 register reads could return inconsistent values,
each time the "seconds" register changes. This could lead to an about
1-second error in the reported time.
Add logic to ensure the "seconds" and "nanoseconds" values are consistent.

commit 7af037c39b600bac2c716dd1228e8ddbe149573f upstream.
Unlike gmac100, gmac1000, gmac4 has 27 DMA registers and they are
located at DMA_CHAN_BASE_ADDR (0x1100). In order for ethtool to dump
gmac4 DMA registers correctly, this commit checks if a net_device has
gmac4 and uses different logic to dump its DMA registers.
This fixes the following KASAN warning, which can normally be triggered
by a command similar like "ethtool -d eth0":

commit d0cfa548dbde354de986911d3913897b5448faad upstream.
When setting Tx sci explicit, the Rx side is expected to use this
sci and not recalculate it from the packet.However, in case of Tx sci
is explicit and send_sci is off, the receiver is wrongly recalculate
the sci from the source MAC address which most likely be different
than the explicit sci.
Fix by preventing such configuration when macsec newlink is established
and return EINVAL error code on such cases.
