BUG: KASAN: slab-out-of-bounds in __build_skb_around+0x235/0x340 net/core/skbuff.c:294
Write of size 32 at addr ffff88802aa172c0 by task syz-executor413/5295
For bpf_prog_test_run_skb(), which uses a kmalloc()ed buffer passed to
build_skb().
When build_skb() is passed a frag_size of 0, it means the buffer came
from kmalloc. In these cases, ksize() is used to find its actual size,
but since the allocation may not have been made to that size, actually
perform the krealloc() call so that all the associated buffer size
checking will be correctly notified (and use the "new" pointer so that
compiler hinting works correctly). Split this logic out into a new
interface, slab_build_skb(), but leave the original 0 checking for now
to catch any stragglers.

mlx5-updates-2022-12-08
1) Support range match action in SW steering
Yevgeny Kliteynik says:
=======================
The following patch series adds support for a range match action in
SW Steering.
SW steering is able to match only on the exact values of the packet fields,
as requested by the user: the user provides mask for the fields that are of
interest, and the exact values to be matched on when the traffic is handled.
The following patch series add new type of action - Range Match, where the
user provides a field to be matched on and a range of values (min to max)
that will be considered as hit.
There are several new notions that were implemented in order to support
Range Match:
- MATCH_RANGES Steering Table Entry (STE): the new STE type that allows
matching the packets' fields on the range of values instead of a specific
value.
- Match Definer: this is a general FW object that defines which fields
in the packet will be referenced by the mask and tag of each STE.
Match definer ID is part of STE fields, and it defines how the HW needs
to interpret the STE's mask/tag values.
Till now SW steering used the definers that were managed by FW and
implemented the STE layout as described by the HW spec.
Now that we're adding a new type of STE, SW steering needs to also be
able to define this new STE's layout, and this is do

Intel Wired LAN Driver Updates 2022-12-08 (ice)
Jacob Keller says:
This series of patches primarily consists of changes to fix some corner
cases that can cause Tx timestamp failures. The issues were discovered and
reported by Siddaraju DH and primarily affect E822 hardware, though this
series also includes some improvements that affect E810 hardware as well.
The primary issue is regarding the way that E822 determines when to generate
timestamp interrupts. If the driver reads timestamp indexes which do not
have a valid timestamp, the E822 interrupt tracking logic can get stuck.
This is due to the way that E822 hardware tracks timestamp index reads
internally. I was previously unaware of this behavior as it is significantly
different in E810 hardware.
Most of the fixes target refactors to ensure that the ice driver does not
read timestamp indexes which are not valid on E822 hardware. This is done by
using the Tx timestamp ready bitmap register from the PHY. This register
indicates what timestamp indexes have outstanding timestamps waiting to be
captured.
Care must be taken in all cases where we read the timestamp registers, and
thus all flows which might have read these registers are refactored. The
ice_ptp_tx_tstamp function is modified to consolidate as much of the logic
relating to these registers as possible. It now handles discarding stale
timestamps which are old or which occurred after a PHC time update. This
replaces previously standalone thread functions like the periodic work
function and the ice_ptp_flush_tx_tracker function.
In addition, some minor cleanups noticed while writing these refactors are
included.
The remaining patches refactor the E822 implementation to remove the
"bypass" mode for timestamps. The E822 hardware has the ability to provide a
more precise timestamp by making use of measurements of the precise way that
packets flow through the hardware pipeline. These measurements are known as
"Vernier" calibration. The "bypass" mode disables many of these measurements
in favor of a faster start up time for Tx and Rx timestamping. Instead, once
these measurements were captured, the driver tries to reconfigure the PHY to
enable the vernier calibrations.
Unfortunately this recalibration does not work. Testing indicates that the
PHY simply remains in bypass mode without the increased timestamp precision.
Remove the attempt at recalibration and always use vernier mode. This has
one disadvantage that Tx and Rx timestamps cannot begin until after at least
one packet of that type goes through the hardware pipeline. Because of this,
further refactor the driver to separate Tx and Rx vernier calibration.
Complete the Tx and Rx independently, enabling the appropriate type of
timestamp as soon as the relevant packet has traversed the hardware
pipeline. This was reported by Milena Olech.
Note that although these might be considered "bug fixes", the required
changes in order to appropriately resolve these issues is large. Thus it
does not feel suitable to send this series to net.

There are two main differences between Spectrum-1 and newer ASICs in
terms of IP-in-IP support:
1. In Spectrum-1, RIFs representing ip6gre tunnels require two entries
in the RIF table.
2. In Spectrum-2 and newer ASICs, packets ingress the underlay (during
encapsulation) and egress the underlay (during decapsulation) via a
special generic loopback RIF.
The first difference was handled in previous patches by adding the
'double_rif_entry' field to the Spectrum-1 operations structure of
ip6gre RIFs. The second difference is handled during RIF creation, by
only creating a generic loopback RIF in Spectrum-2 and newer ASICs.
Therefore, the ip6gre operations can be shared between Spectrum-1 and
newer ASIC in a similar fashion to how the ipgre operations are shared.
Rename the operations to not be Spectrum-2 specific and move them
earlier in the file so that they could later be used for Spectrum-1.

The elan touchscreen datasheet says that the reset GPIO only needs to
be asserted for 500us in order to reset the regulator. The problem is
that some boards need a level shifter between the signals on the GPIO
controller and the signals on the touchscreen. All of these extra
components on the line can slow the transition of the signals. On one
board, we measured the reset line and saw that it took almost 1.8ms to
go low. Even after we bumped up the "drive strength" of the signal
from the default 2mA to 8mA we still saw it take 421us for the signal
to go low.
In order to account for this let's lengthen the amount of time that we
keep the reset asserted. Let's bump it up from 500us to 5000us.
That's still a relatively short amount of time and is much safer.
It should be noted that this fixes real problems. Case in point:
1. The touchscreen power rail may be shared with another device (like
an eDP panel). That means that at probe time power might already be
on.
2. In probe we grab the reset GPIO and assert it (make it low).
3. We turn on power (a noop since it was already on).
4. We wait 500us.
5. We deassert the reset GPIO.
With the above case and only a 500us delay we saw only a partial reset
asserted, which is bad. Giving it 5ms is overkill but feels safer in
case someone else has a different level shifter setup.
Note that bumping up the delay to 5000 means that some configs yell
about using udelay(). We'll change to using usleep_range(). We give a
small range here because:
- This isn't a delay that happens very often so we don't need to worry
about giving a big range to allow for power efficiency.
- usleep_range() is known to almost always pick the upper bound and
delay that long and we really don't want to slow down the power on
of the touchscreen that much.

With the intent of removing driver selects from Kconfig.socs in
arch/riscv, essential drivers that were being selected there could
instead by enabled by defaulting them to the value of the SoC's Kconfig
symbol.
Do so here & drop the depend on RISC-V - the SOC_ symbols are only
defined there anyway.

Today multipath offload is only supported when the number of

This patch solve it by enabling multipath offload per NIC if
2 nexthops of the route are its uplinks.

TC police action may configure the maximum packet size to be handled by
the policer, in addition to byte/packet rate.
MTU check is realized in hardware using the range destination, specifying
a hit ft, if packet len is in the range, or miss ft otherwise.
Instantiate mtu green/red flow tables with a single match-all rule.
Add the green/red actions to the hit/miss table accordingly.

Up until now miss address in all the STEs was used to connect miss lists
and to link the last STE in the list to end anchor.
Match range STE will require special handling because its miss address is
part of the 'action'. That is, range action has hit and miss addresses.
Since the range action is always the last action, need to make sure that
its miss address isn't overwritten by the end anchor.
Adding new function mlx5dr_ste_is_miss_addr_set() to answer the question
whether the STE's miss address has already been set as part of STE
initialization. Use a callback that always returns false right now. Once
match range is added, a different callback will be used for that STE type.

In many cases different actions will ask for the same definer format.
Instead of allocating new definer general object and running out of
definers, have an xarray of allocated definers and keep track of their
usage with refcounts: allocate a new definer only when there isn't
one with the same format already created, and destroy definer only
when its refcount runs down to zero.
