When GEM is in SGMII mode and disabled as a wakeup source, the power

This change adds support for not enabling carrier during TUNSETIFF
interface creation by specifying the IFF_NO_CARRIER flag.
Our tests make heavy use of tun interfaces. In some scenarios, the test
process creates the interface but another process brings it up after the
interface is discovered via netlink notification. In that case, it is
not possible to create a tun/tap interface with carrier off without it
racing against the bring up. Immediately setting carrier off via
TUNSETCARRIER is still too late.

A handful of awaited fixes here - revert of the FEC changes, bluetooth
fix, fixes for iwlwifi spew.
We added a warning in PHY/MDIO code which is triggering on a couple of

the week we'll drop it and re-add for 6.1.
I've added a new "follow up fixes" section for fixes to fixes in

problematic or that more testing time would have caught them. So
likely a one time thing.

When reading the timestamp is required bnxt_tx_int() hands
over the ownership of the completed skb to the PTP worker.
The skb should not be used afterwards, as the worker may
run before the rest of our code and free the skb, leading
to a use-after-free.
Since dev_kfree_skb_any() accepts NULL make the loss of
ownership more obvious and set skb to NULL.

There is a separate receive path for small packets (under 256 bytes).
Instead of allocating a new dma-capable skb to be used for the next packet,
this path allocates a skb and copies the data into it (reusing the existing
sbk for the next packet). There are two bytes of junk data at the beginning
of every packet. I believe these are inserted in order to allow aligned DMA
and IP headers. We skip over them using skb_reserve. Before copying over
the data, we must use a barrier to ensure we see the whole packet. The
current code only synchronizes len bytes, starting from the beginning of
the packet, including the junk bytes. However, this leaves off the final
two bytes in the packet. Synchronize the whole packet.
To reproduce this problem, ping a HME with a payload size between 17 and
214
$ ping -s 17 <hme_address>
which will complain rather loudly about the data mismatch. Small packets
(below 60 bytes on the wire) do not have this issue. I suspect this is
related to the padding added to increase the minimum packet size.

We currently check the MokSBState variable to decide whether we should
treat UEFI secure boot as being disabled, even if the firmware thinks
otherwise. This is used by shim to indicate that it is not checking
signatures on boot images. In the kernel, we use this to relax lockdown
policies.
However, in cases where shim is not even being used, we don't want this
variable to interfere with lockdown, given that the variable may be
non-volatile and therefore persist across a reboot. This means setting
it once will persistently disable lockdown checks on a given system.
So switch to the mirrored version of this variable, called MokSBStateRT,
which is supposed to be volatile, and this is something we can check.

When booting the x86 kernel via EFI using the LoadImage/StartImage boot
services [as opposed to the deprecated EFI handover protocol], the setup
header is taken from the image directly, and given that EFI's LoadImage
has no Linux/x86 specific knowledge regarding struct bootparams or
struct setup_header, any absolute addresses in the setup header must
originate from the file and not from a prior loading stage.
Since we cannot generally predict where LoadImage() decides to load an
image (*), such absolute addresses must be treated as suspect: even if a
prior boot stage intended to make them point somewhere inside the
[signed] image, there is no way to validate that, and if they point at
an arbitrary location in memory, the setup_data nodes will not be
covered by any signatures or TPM measurements either, and could be made
to contain an arbitrary sequence of SETUP_xxx nodes, which could
interfere quite badly with the early x86 boot sequence.
(*) Note that, while LoadImage() does take a buffer/size tuple in
addition to a device path, which can be used to provide the image
contents directly, it will re-allocate such images, as the memory
footprint of an image is generally larger than the PE/COFF file
representation.

====================
pull-request: can 2022-09-21
The 1st patch is by me, targets the flexcan driver and fixes a
potential system hang on single core systems under high CAN packet
rate.
The next 2 patches are also by me and target the gs_usb driver. A
potential race condition during the ndo_open callback as well as the
return value if the ethtool identify feature is not supported are
fixed.

It seems the recent libbpf got more strict about the section name.
I'm seeing a failure like this:
$ sudo ./perf stat -a --bpf-counters --for-each-cgroup ^. sleep 1
libbpf: prog 'on_cgrp_switch': missing BPF prog type, check ELF section name 'perf_events'
libbpf: prog 'on_cgrp_switch': failed to load: -22
libbpf: failed to load object 'bperf_cgroup_bpf'
libbpf: failed to load BPF skeleton 'bperf_cgroup_bpf': -22
Failed to load cgroup skeleton
The section name should be 'perf_event' (without the trailing 's').
Although it's related to the libbpf change, it'd be better fix the
section name in the first place.
Fixes: 944138f048 ("perf stat: Enable BPF counter with --for-each-cgroup")

If aq_nic_stop() fails, aq_ndev_close() returns err without calling
aq_nic_deinit() to release the relevant memory and resource, which
will lead to a memory leak.
We can fix it by deleting the if condition judgment and goto statement to
call aq_nic_deinit() directly after aq_nic_stop() to fix the memory leak.

====================
netfilter: bugfixes for net
The following set contains netfilter fixes for the *net* tree.
Regressions (rc only):
recent ebtables crash fix was incomplete, it added a memory leak.
The patch to fix possible buffer overrun for BIG TCP in ftp conntrack
tried to be too clever, we cannot re-use ct->lock: NAT engine might
grab it again -> deadlock. Revert back to a global spinlock.
Both from myself.
Remove the documentation for the recently removed
'nf_conntrack_helper' sysctl as well, from Pablo Neira.
The static_branch_inc() that guards the 'chain stats enabled' path
needs to be deferred further, until the entire transaction was created.
From Tetsuo Handa.
Older bugs:
Since 5.3:
nf_tables_addchain may leak pcpu memory in error path when
offloading fails. Also from Tetsuo Handa.
