After commit ed4246d37f3b ("scsi: sd: REQUEST SENSE for
BLIST_IGN_MEDIA_CHANGE devices in runtime_resume()"), the following crash
was observed.
static int sd_resume_runtime(struct device *dev)
{
struct scsi_disk *sdkp = dev_get_drvdata(dev);
struct scsi_device *sdp = sdkp->device; // sdkp == NULL and crash
if (sdp->ignore_media_change) {
...
}
It is possible for sdkp to be NULL in sd_resume_runtime(). To fix this
crash, follow sd_resume() to test if sdkp is NULL before dereferencing it.
Crash:

Some systems such as the Microsoft Surface Laptop 4 leave interrupts
enabled and configured for use in sleep states on boot, which cause
unexpected behaviour such as spurious wakes and failed resumes in
s2idle states.
As interrupts should not be enabled until they are claimed and
explicitly enabled, disabling any interrupts mistakenly left enabled by
firmware should be safe.

When I added IGMPv3 support I decided to follow the RFC for computing
the GMI dynamically:
" 8.4. Group Membership Interval
The Group Membership Interval is the amount of time that must pass
before a multicast router decides there are no more members of a
group or a particular source on a network.
This value MUST be ((the Robustness Variable) times (the Query
Interval)) plus (one Query Response Interval)."
But that actually is inconsistent with how the bridge used to compute it
for IGMPv2, where it was user-configurable that has a correct default value
but it is up to user-space to maintain it. This would make it consistent
with the other timer values which are also maintained correct by the user
instead of being dynamically computed. It also changes back to the previous
user-expected GMI behaviour for IGMPv3 queries which were supported before
IGMPv3 was added. Note that to properly compute it dynamically we would
need to add support for "Robustness Variable" which is currently missing.

sk_stream_kill_queues() can be called on close when there are
still outstanding skbs to transmit. Those skbs may try to queue
notifications to the error queue (e.g. timestamps).
If sk_stream_kill_queues() purges the queue without taking
its lock the queue may get corrupted, and skbs leaked.
This shows up as a warning about an rmem leak:
WARNING: CPU: 24 PID: 0 at net/ipv4/af_inet.c:154 inet_sock_destruct+0x...
The leak is always a multiple of 0x300 bytes (the value is in
%rax on my builds, so RAX: 0000000000000300). 0x300 is truesize of
an empty sk_buff. Indeed if we dump the socket state at the time
of the warning the sk_error_queue is often (but not always)
corrupted. The ->next pointer points back at the list head,
but not the ->prev pointer. Indeed we can find the leaked skb
by scanning the kernel memory for something that looks like
an skb with ->sk = socket in question, and ->truesize = 0x300.
The contents of ->cb[] of the skb confirms the suspicion that
it is indeed a timestamp notification (as generated in
__skb_complete_tx_timestamp()).
Removing purging of sk_error_queue should be okay, since
inet_sock_destruct() does it again once all socket refs
are gone. Eric suggests this may cause sockets that go
thru disconnect() to maintain notifications from the
previous incarnations of the socket, but that should be
okay since the race was there anyway, and disconnect()
is not exactly dependable.
Thanks to Jonathan Lemon and Omar Sandoval for help at various
stages of tracing the issue.

Commit 406f42fa0d3c ("net-next: When a bond have a massive amount
of VLANs...") introduced a rbtree for faster Ethernet address look
up. To maintain netdev->dev_addr in this tree we need to make all
the writes to it got through appropriate helpers.
Copy the address into an array on the stack, then call
eth_hw_addr_set().

eth_hw_addr_set() is after error checking, this should
be fine, error propagates all the way to failing probe.

The last argument of device_create() call should be a template string.
The tap_name variable should be the argument to the string, but not the
argument of the call itself. We should add the template string and turn
tap_name into its argument.

Saeed Mahameed says:
====================
mlx5-updates-2021-10-15
1) From Rongwei Liu:
Use system_image_guid and native_port_num when bonding.
Don't relay on PCIe ids anymore.
With some specific NIC, the physical devices may have PCIe IDs like
0001:01:00.0/1 and 0002:02:00.0/1. All of these devices should have
the same system_image_guid and device index can be queried from
native_port_num.
For matching sibling devices/port of the same HCA, compare the HCA
GUID reported on each device rather than just assuming PCIe ids have
similar attributes.
2) From Amir Tzin: Use HCA defined Timouts
Replace hard coded timeouts with values stored by firmware in default
timeouts register (DTOR). Timeouts are read during driver load. If DTOR
is not supported by firmware then fallback to hard coded defaults
instead.
3) From Shay Drory: Disable roce at HCA level
Disable RoCE in Firmware when devlink roce parameter is set to off.
4) A small set of trivial cleanups

100GbE Intel Wired LAN Driver Updates 2021-10-14
Maciej Machnikowski says:
Extend the driver implementation to support PTP pins on E810-T and
derivative devices.
E810-T adapters are equipped with:
- 2 external bidirectional SMA connectors
- 1 internal TX U.FL shared with SMA1
- 1 internal RX U.FL shared with SMA2
The SMA and U.FL configuration is controlled by the external
multiplexer.
E810-T Derivatives are equipped with:
- 2 1PPS outputs on SDP20 and SDP22
- 2 1PPS inputs on SDP21 and SDP23
---
v2:
- Remove defensive programming check and simplify return statement
(Patch 3)
- Remove unnecessary parentheses (Patch 4)

mptcp: A few fixes
This set has three separate changes for the net-next tree:
Patch 1 guarantees safe handling and a warning if a NULL value is
encountered when gathering subflow data for the MPTCP_SUBFLOW_ADDRS
socket option.
Patch 2 increases the default number of subflows allowed per MPTCP
connection.
Patch 3 makes an existing function 'static'.

The current default does not allowing additional subflows, mostly
as a safety restriction to avoid uncontrolled resource consumption
on busy servers.
Still the system admin and/or the application have to opt-in to
MPTCP explicitly. After that, they need to change (increase) the
default maximum number of additional subflows.
Let set that to reasonable default, and make end-users life easier.
Additionally we need to update some self-tests accordingly.

Coverity complains of a possible NULL dereference in
mptcp_getsockopt_subflow_addrs():
861 } else if (sk->sk_family == AF_INET6) {
3. returned_null: inet6_sk returns NULL. [show details]
4. var_assigned: Assigning: np = NULL return value from inet6_sk.
862 const struct ipv6_pinfo *np = inet6_sk(sk);
Fix this by checking for NULL.
