As can be seen from strace, there are two TLS records sent,
i) 'test_read_peek' and ii) '_mult_recs\0' where we end up
peeking 'test_read_peektest_read_peektest'. This is clearly
wrong, and what happens is that given peek cannot call into
tls_sw_advance_skb() to unpause strparser and proceed with
the next skb, we end up looping over the current one, copying
the 'test_read_peek' over and over into the user provided
buffer.
Here, we can only peek into the currently held skb (current,
full TLS record) as otherwise we would end up having to hold
all the original skb(s) (depending on the peek depth) in a
separate queue when unpausing strparser to process next
records, minimally intrusive is to return only up to the
current record's size (which likely was what c46234ebb4
("tls: RX path for ktls") originally intended as well). Thus,
after patch we properly peek the first record:

When async support was added it needed to access the sk from the async
callback to report errors up the stack. The patch tried to use space
after the aead request struct by directly setting the reqsize field in
aead_request. This is an internal field that should not be used
outside the crypto APIs. It is used by the crypto code to define extra
space for private structures used in the crypto context. Users of the
API then use crypto_aead_reqsize() and add the returned amount of
bytes to the end of the request memory allocation before posting the
request to encrypt/decrypt APIs.
So this breaks (with general protection fault and KASAN error, if
enabled) because the request sent to decrypt is shorter than required
causing the crypto API out-of-bounds errors. Also it seems unlikely the
sk is even valid by the time it gets to the callback because of memset
in crypto layer.
Anyways, fix this by holding the sk in the skb->sk field when the
callback is set up and because the skb is already passed through to
the callback handler via void* we can access it in the handler. Then
in the handler we need to be careful to NULL the pointer again before
kfree_skb. I added comments on both the setup (in tls_do_decryption)
and when we clear it from the crypto callback handler
tls_decrypt_done(). After this selftests pass again and fixes KASAN
errors/warnings.

hv_netvsc: associate VF and PV device by serial number
The Hyper-V implementation of PCI controller has concept of 32 bit serial number
(not to be confused with PCI-E serial number). This value is sent in the protocol
from the host to indicate SR-IOV VF device is attached to a synthetic NIC.
Using the serial number (instead of MAC address) to associate the two devices
avoids lots of potential problems when there are duplicate MAC addresses from
tunnels or layered devices.
The patch set is broken into two parts, one is for the PCI controller
and the other is for the netvsc device. Normally, these go through different
trees but sending them together here for better review. The PCI changes
were submitted previously, but the main review comment was "why do you
need this?". This is why.

The Hyper-V host API for PCI provides a unique "serial number" which
can be used as basis for sysfs PCI slot table. This can be useful
for cases where userspace wants to find the PCI device based on
serial number.
When an SR-IOV NIC is added, the host sends an attach message
with serial number. The kernel doesn't use the serial number, but
it is useful when doing the same thing in a userspace driver such
as the DPDK. By having /sys/bus/pci/slots/N it provides a direct
way to find the matching PCI device.
There maybe some cases where serial number is not unique such
as when using GPU's. But the PCI slot infrastructure will handle
that.
This has a side effect which may also be useful. The common udev
network device naming policy uses the slot information (rather
than PCI address).

Net drivers using phylink shouldn't mess with the link carrier
themselves and should let phylink manage it. The mvpp2 driver wasn't
following this best practice as the mac_config() function made calls to
change the link carrier state. This led to wrongly reported carrier link
state which then triggered other issues. This patch fixes this
behaviour.
But the PPv2 driver relied on this misbehaviour in two cases: for fixed
links and when not using phylink (ACPI mode). The later was fixed by
adding an explicit call to link_up(), which when the ACPI mode will use
phylink should be removed.
The fixed link case was relying on the mac_config() function to set the
link up, as we found an issue in phylink_start() which assumes the
carrier is off. If not, the link_up() function is never called. To fix
this, a call to netif_carrier_off() is added just before phylink_start()
so that we do not introduce a regression in the driver.

While at first mtd_part_of_parse() would just call
of_get_chil_by_name(), it has been patched to deal with sub-partitions
and will now directly manipulate the node returned by mtd_get_of_node()
if the MTD device is a partition.
A of_node_put() was a bit below in the code, to balance the
of_get_child_by_name(). However, despite its name, mtd_get_of_node()
does not take a reference on the OF node. It is a simple helper hiding
some pointer logic to retrieve the OF node related to an MTD
device.
The direct effect of such unbalanced reference counting is visible by
rmmod'ing any module that would have added MTD partitions:
OF: ERROR: Bad of_node_put() on <of_path_to_partition>
As it seems normal to get a reference on the OF node during the
of_property_for_each_string() that follows, add a call to
of_node_get() when relevant.

Instructions for modifying the PSTATE fields which were not supported
in the older toolchains (e.g, PAN, UAO) are generated using macros.
We have so far used the normal sys_reg() helper for defining the PSTATE
fields. While this works fine, it is really difficult to correlate the
code with the Arm ARM definition.
As per Arm ARM, the PSTATE fields are defined only using Op1, Op2 fields,
with fixed values for Op0, CRn. Also the CRm field has been reserved
for the Immediate value for the instruction. So using the sys_reg()
looks quite confusing.
This patch cleans up the instruction helpers by bringing them
in line with the Arm ARM definitions to make it easier to correlate
code with the document. No functional changes.

This patch simply fix part of the documentation on the HTM code.
This fixes reference to old fields that were renamed in commit
000ec280e3 ("powerpc: tm: Rename transct_(*) to ck(\1)_state")
It also documents better the flow after commit eb5c3f1c86 ("powerpc:
Always save/restore checkpointed regs during treclaim/trecheckpoint"),
where tm_recheckpoint can recheckpoint what is in ck{fp,vr}_state
blindly.

Test tm-tmspr might exit before all threads stop executing, because it just
waits for the very last thread to join before proceeding/exiting.
This patch makes sure that all threads that were created will join before
proceeding/exiting.
This patch also guarantees that the amount of threads being created is equal
to thread_num.

The same connection mark can be set on flows belonging to different
address families. This commit adds support for filtering on the L3
protocol when flushing connection track entries. If no protocol is
specified, then all L3 protocols match.
In order to avoid code duplication and a redundant check, the protocol
comparison in ctnetlink_dump_table() has been removed. Instead, a filter
is created if the GET-message triggering the dump contains an address
family. ctnetlink_filter_match() is then used to compare the L3
protocols.

Release the committed transaction log from a work queue, moving
expensive synchronize_rcu out of the locked section and providing
opportunity to batch this.
On my test machine this cuts runtime of nft-test.py in half.

->destroy is only allowed to free data, or do other cleanups that do not
have side effects on other state, such as visibility to other netlink
requests.
Such things need to be done in ->deactivate.
As a transaction can fail, we need to make sure we can undo such
operations, therefore ->activate() has to be provided too.
So print a warning and refuse registration if expr->ops provides
only one of the two operations.

lpss_iosf_enter_d3_state() checks if all hw-blocks using the DMA
controllers are in d3 before powering down the DMA controllers.
But on devices, where the I2C bus connected to the PMIC is shared by
the PUNIT, the controller for that bus will never reach d3 since it has
an effectively empty _PS3 method. Instead it appears to automatically
power-down during S0i3 and we never see it as being in d3.
This causes the DMA controllers to never be powered-down on these devices,
causing them to never reach S0i3. This commit uses the ACPI _SEM method
to detect if an I2C bus is shared with the PUNIT and if it is, it removes
it from the mask of devices which lpss_iosf_enter_d3_state() checks for.
This fixes these devices never reaching any S0ix states.
