522b1d6921 ("x86/cpu/amd: Add a Zenbleed fix")
provided a fix for the Zen2 VZEROUPPER data corruption bug affecting
a range of CPU models, but the AMD Custom APU 0405 found on SteamDeck
was not listed, although it is clearly affected by the vulnerability.
Add this CPU variant to the Zenbleed erratum list, in order to
unconditionally enable the fallback fix until a proper microcode update
is available.

The WinSystems WS16C48 I/O address region spans offsets 0x0 through 0xA,
which is a total of 11 bytes. Fix the WS16C48_EXTENT define to the
correct value of 11 so that access to necessary device registers is
properly requested in the ws16c48_probe() callback by the
devm_request_region() function call.

We want to fix the serial core port DEVNAME to use a port id of the
hardware specific controller port instance instead of the port->line.
For example, the 8250 driver sets up a number of serial8250 ports
initially that can be inherited by the hardware specific driver. At that
the port->line no longer decribes the port's relation to the serial core
controller instance.
Let's fix the issue by assigning port->port_id for each serial core
controller port instance.

In commit 9b9c8195f3 ("tty: n_gsm: fix UAF in gsm_cleanup_mux"), the UAF

gsm_cleanup_mux(), which caused this UAF.
The UAF problem is triggered by the following race:

----------------------- -----------------------
gsm_cleanup_mux();
dlci = gsm->dlci[0];
mutex_lock(&gsm->mutex);

gsm_dlci_release(gsm->dlci[i]);
gsm->dlci[i] = NULL;

mutex_lock(&gsm->mutex);
dlci->dead = true; //UAF
Fix it by assigning values after mutex_lock().

If we repeatedly fail to fake offline memory to unplug it, we won't be
sending any unplug requests to the device. However, we only check if the
config changed when sending such (un)plug requests.
We could end up trying for a long time to unplug memory, even though
the config changed already and we're not supposed to unplug memory
anymore. For example, the hypervisor might detect a low-memory situation
while unplugging memory and decide to replug some memory. Continuing
trying to unplug memory in that case can be problematic.
So let's check on a more regular basis.

In case offline_and_remove_memory() fails in SBM, we leave a completely
unplugged Linux memory block stick around until we try plugging memory
again. We won't try removing that memory block again.
offline_and_remove_memory() may, for example, fail if we're racing with
another alloc_contig_range() user, if allocating temporary memory fails,
or if some memory notifier rejected the offlining request.
Let's handle that case better, by simple retrying to offline and remove
such memory.
Tested using CONFIG_MEMORY_NOTIFIER_ERROR_INJECT.

Just like we do with alloc_contig_range(), let's convert all unknown

When "unsafe unplug" is enabled, we don't fake-offline all memory ahead of
actual memory offlining using alloc_contig_range(). Instead, we rely on
offline_pages() to also perform actual page migration, which might fail
or take a very long time.
In that case, it's possible to easily run into endless loops that cannot be
aborted anymore (as offlining is triggered by a workqueue then): For
example, a single (accidentally) permanently unmovable page in
ZONE_MOVABLE results in an endless loop. For ZONE_NORMAL, races between
isolating the pageblock (and checking for unmovable pages) and
concurrent page allocation are possible and similarly result in endless
loops.
The idea of the unsafe unplug mode was to make it possible to more
reliably unplug large memory blocks. However, (a) we really should be
tackling that differently, by extending the alloc_contig_range()-based
mechanism; and (b) this mode is not the default and as far as I know,
it's unused either way.
So let's simply get rid of it.

We were allocating irq vectors at the time the aux dev was probed,
but that is before the PCI VF is assigned to a separate iommu domain
by vhost_vdpa. Because vhost_vdpa later changes the iommu domain the
interrupts do not work.
Instead, we can allocate the irq vectors later when we see DRIVER_OK and
know that the reassignment of the PCI VF to an iommu domain has already
happened.

Our driver sets a mac if the HW is 00:..:00 so we need to be sure to
advertise VIRTIO_NET_F_MAC even if the HW doesn't. We also need to be
sure that virtio_net sees the VIRTIO_NET_F_MAC and doesn't rewrite the
mac address that a user may have set with the vdpa utility.
After reading the hw_feature bits, add the VIRTIO_NET_F_MAC to the driver's
supported_features and use that for reporting what is available. If the
HW is not advertising it, be sure to strip the VIRTIO_NET_F_MAC before
finishing the feature negotiation. If the user specifies a device_features
bitpattern in the vdpa utility without the VIRTIO_NET_F_MAC set, then
don't set the mac.

Kernel uses `struct virtio_net_ctrl_rss` to save command-specific-data
for both the VIRTIO_NET_CTRL_MQ_HASH_CONFIG and
VIRTIO_NET_CTRL_MQ_RSS_CONFIG commands.
According to the VirtIO standard, "Field reserved MUST contain zeroes.
It is defined to make the structure to match the layout of
virtio_net_rss_config structure, defined in 5.1.6.5.7.".
Yet for the VIRTIO_NET_CTRL_MQ_HASH_CONFIG command case, the `max_tx_vq`
field in struct virtio_net_ctrl_rss, which corresponds to the
`reserved` field in struct virtio_net_hash_config, is not zeroed,
thereby violating the VirtIO standard.
This patch solves this problem by zeroing this field in
virtnet_init_default_rss().

Current release - regressions:

- eth: prestera: fix handling IPv4 routes with nexthop IDs

- tunnels: fix generating ipv4 PMTU error on non-linear skbs
- nexthop: fix infinite nexthop bucket dump when using maximum

Merge tag 'net-6.5-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net
Pull networking fixes from Jakub Kicinski:
"Including fixes from netfilter, wireless and bpf.
Still trending up in size but the good news is that the "current"
regressions are resolved, AFAIK.
We're getting weirdly many fixes for Wake-on-LAN and suspend/resume
handling on embedded this week (most not merged yet), not sure why.
But those are all for older bugs.
Current release - regressions:
- tls: set MSG_SPLICE_PAGES consistently when handing encrypted data
over to TCP
Current release - new code bugs:
- eth: mlx5: correct IDs on VFs internal to the device (IPU)
Previous releases - regressions:
- phy: at803x: fix WoL support / reporting on AR8032
- bonding: fix incorrect deletion of ETH_P_8021AD protocol VID from
slaves, leading to BUG_ON()
- tun: prevent tun_build_skb() from exceeding the packet size limit
- wifi: rtw89: fix 8852AE disconnection caused by RX full flags
- eth/PCI: enetc: fix probing after 6fffbc7ae1 ("PCI: Honor
firmware's device disabled status"), keep PCI devices around even
if they are disabled / not going to be probed to be able to apply
quirks on them
- eth: prestera: fix handling IPv4 routes with nexthop IDs
Previous releases - always broken:
- netfilter: re-work garbage collection to avoid races between
user-facing API and timeouts
- tunnels: fix generating ipv4 PMTU error on non-linear skbs
- nexthop: fix infinite nexthop bucket dump when using maximum
nexthop ID
- wifi: nl80211: fix integer overflow in nl80211_parse_mbssid_elems()
Misc:
- unix: use consistent error code in SO_PEERPIDFD
- ipv6: adjust ndisc_is_useropt() to include PREFIX_INFO, in prep for
upcoming IETF RFC"

mlx5_vdpa_destroy_mr can be called from .set_map with data ASID after
the control virtqueue ASID iotlb has been populated. The control vq
iotlb must not be cleared, since it will not be populated again.
So call the ASID aware destroy function which makes sure that the
right vq resource is destroyed.

The mr->initialized flag is shared between the control vq and data vq
part of the mr init/uninit. But if the control vq and data vq get placed
in different ASIDs, it can happen that initializing the control vq will
prevent the data vq mr from being initialized.
This patch consolidates the control and data vq init parts into their
own init functions. The mr->initialized will now be used for the data vq
only. The control vq currently doesn't need a flag.
The uninitializing part is also taken care of: mlx5_vdpa_destroy_mr got
split into data and control vq functions which are now also ASID aware.

The IRQ injection work used spin_lock_irq() to protect the
scheduling of the softirq, but spin_lock_bh() should be
used.
With spin_lock_irq(), we noticed delay of more than 6
seconds between the time a NAPI polling work is scheduled
and the time it is executed.
