SAR GEO offsets are not supported on 3160 devices. The code was
refactored and caused us to start sending the command anyway, which
causes a FW assertion failure. Fix that only considering this feature
supported on FW API with major version is 17 if the device is not
3160.
Additionally, fix the caller of iwl_mvm_sar_geo_init() so that it
checks for the return value, which it was ignoring.

This feature has been deprecated and should not be used anymore. With
newer firmwares, namely *-67.ucode and above, trying to use it causes an
assertion failure in the FW, similar to this:
[Tue Jan 11 20:05:24 2022] iwlwifi 0000:04:00.0: 0x00001062 | ADVANCED_SYSASSERT
In order to prevent this feature from being used, remove it entirely
and get rid of the Kconfig option that
enables it (IWLWIFI_BCAST_FILTERING).

When we register and we are in link protection passive, meaning
that the host can't touch the device, report RFKILL immediately
upon register() and don't wait for the CSME firmware to let us
know again about the link protection state.
What happens if we wait is that the host will not see RFKILL soon
enough and we'll have a window of time during which it can bring
up the device which will request ownership.

iwlmei can trigger a hardware RFKILL when the CSME firmware
does not want the host to touch the device.
But then, iwlmvm reports RFKILL which makes cfg80211 update
iwlmvm about RFKILL. iwlmvm then thinks there is a change in
the _software_ rfkill and it calls rfkill_blocked() to fetch
the RFKILL state. This returns that RFKILL is blocked (because
of iwlmei) and iwlmvm tells iwlmei that _software_ RFKILL is
asserted.
This is a bug of course.
Fix this by checking explicitly the software RFKILL state and
not the overall RFKILL state.

The shared area is a DMA memory allocated in the host and
mapped so that the host and the CSME firmware can
exchange data. It is mapped through a dedicated PCI device
that is driven by the mei bus driver.
The bus driver is in charge of allocating and mapping this
memory. It also needs to configure the CSME firmware with
a specific set of commands, so that the CSME firmware will
know that this memory is meant to be used by its internal
WLAN module.
For this, the CSME firmware first needs to completely
initialize its WLAN module and only then get the mapping
request.
The problem is that the mei bus enumeration completes
before the WLAN is completely ready. This means that
the WLAN module's initialization is racing with iwlmei's
allocation and mapping flow.
Testing showed a problem in resume flows where iwlmei
was too fast and the DMA mapping failed.
Add a retry mechanism to make sure that we will succeed
to map the memory.

The check makes sure that we can look at the ip header.
We first need to check that the basic ip header (20 bytes)
can be pulled before we look at the field that will teach
us how long is the ip header. This is why there are two
checks.
The second check was wrong and smatch pointed that
sizeof(ip_hdrlen(skb) - sizeof(*iphdr)) can't be right.
Looking at the code again made me think that we really
need ip_hdrlen(skb) since we want to make sure all the
IP header is in the buffer header. This will allow us
to set the transport offset and from there to look
at the transport header (TCP / UDP).

There are a couple of bugs in this function:
1. It is declared as a non-static function, even though
it's only used in one file.
2. Its return value should be of type u32 but it returns
(in some cases) -1.
Fix them by making this function static and returning an
error value of type unsigned.
In addition, we're assigning the return value of this function
as the legacy rate even if the function returned an error value.
Fix this by assigning the lowest rate in this case.

This started out with me noticing that "dom0_max_vcpus=<N>" with <N>
larger than the number of physical CPUs reported through ACPI tables
would not bring up the "excess" vCPU-s. Addressing this is the primary
purpose of the change; CPU maps handling is being tidied only as far as
is necessary for the change here (with the effect of also avoiding the
setting up of too much per-CPU infrastructure, i.e. for CPUs which can
never come online).
Noticing that xen_fill_possible_map() is called way too early, whereas
xen_filter_cpu_maps() is called too late (after per-CPU areas were
already set up), and further observing that each of the functions serves
only one of Dom0 or DomU, it looked like it was better to simplify this.
Use the .get_smp_config hook instead, uniformly for Dom0 and DomU.
xen_fill_possible_map() can be dropped altogether, while
xen_filter_cpu_maps() is re-purposed but not otherwise changed.

After commit 2fd3fb0be1d1 ("kasan, vmalloc: unpoison VM_ALLOC pages
after mapping"), non-VM_ALLOC mappings will be marked as accessible
in __get_vm_area_node() when KASAN is enabled. But now the flag for
ringbuf area is VM_ALLOC, so KASAN will complain out-of-bound access
after vmap() returns. Because the ringbuf area is created by mapping
allocated pages, so use VM_MAP instead.
After the change, info in /proc/vmallocinfo also changes from
[start]-[end] 24576 ringbuf_map_alloc+0x171/0x290 vmalloc user

Controller deletion/reset, immediately followed by or concurrent with
a reconnect, is hard failing the connect attempt resulting in a
complete loss of connectivity to the controller.
In the connect request, fabrics looks for an existing controller with
the same address components and aborts the connect if a controller
already exists and the duplicate connect option isn't set. The match
routine filters out controllers that are dead or dying, so they don't
interfere with the new connect request.
When NVME_CTRL_DELETING_NOIO was added, it missed updating the state
filters in the nvmf_ctlr_matches_baseopts() routine. Thus, when in this
new state, it's seen as a live controller and fails the connect request.
Correct by adding the DELETING_NIO state to the match checks.

neigh_managed_work
syzkaller was able to trigger a deadlock for NTF_MANAGED entries [0]:
kworker/0:16/14617 is trying to acquire lock:
ffffffff8d4dd370 (&tbl->lock){++-.}-{2:2}, at: ___neigh_create+0x9e1/0x2990 net/core/neighbour.c:652
[...]
but task is already holding lock:
ffffffff8d4dd370 (&tbl->lock){++-.}-{2:2}, at: neigh_managed_work+0x35/0x250 net/core/neighbour.c:1572
The neighbor entry turned to NUD_FAILED state, where __neigh_event_send()
triggered an immediate probe as per commit cd28ca0a3dd1 ("neigh: reduce
arp latency") via neigh_probe() given table lock was held.
One option to fix this situation is to defer the neigh_probe() back to
the neigh_timer_handler() similarly as pre cd28ca0a3dd1. For the case
of NTF_MANAGED, this deferral is acceptable given this only happens on
actual failure state and regular / expected state is NUD_VALID with the
entry already present.
The fix adds a parameter to __neigh_event_send() in order to communicate
whether immediate probe is allowed or disallowed. Existing call-sites
of neigh_event_send() default as-is to immediate probe. However, the
neigh_managed_work() disables it via use of neigh_event_send_probe().

tcp_shift_skb_data() might collapse three packets into a larger one.
P_A, P_B, P_C -> P_ABC
Historically, it used a single tcp_skb_can_collapse_to(P_A) call,
because it was enough.
In commit 85712484110d ("tcp: coalesce/collapse must respect MPTCP extensions"),
this call was replaced by a call to tcp_skb_can_collapse(P_A, P_B)
But the now needed test over P_C has been missed.
This probably broke MPTCP.
Then later, commit 9b65b17db723 ("net: avoid double accounting for pure zerocopy skbs")
added an extra condition to tcp_skb_can_collapse(), but the missing call
from tcp_shift_skb_data() is also breaking TCP zerocopy, because P_A and P_C
might have different skb_zcopy_pure() status.

The eDP link rate reported by the DP_MAX_LINK_RATE dpcd register (0xa) is
contradictory to the highest rate supported reported by
EDID (0xc = LINK_RATE_RBR2). The effects of this compounded with commit
'4a8ca46bae8a ("drm/amd/display: Default max bpc to 16 for eDP")' results
in no display modes being found and a dark panel.
For now, simply force the maximum supported link rate for the eDP attached
2018 15" Apple Retina panels.
Additionally, we must also check the firmware revision since the device ID
reported by the DPCD is identical to that of the more capable 16,1,
incorrectly quirking it. We also use said firmware check to quirk the
refreshed 15,1 models with Vega graphics as they use a slightly newer
firmware version.

Both msgr1 and msgr2 in crc mode are zero copy in the sense that
message data is read from the socket directly into the destination
buffer. We assume that the destination buffer is stable (i.e. remains
unchanged while it is being read to) though. Otherwise, CRC errors
ensue:
libceph: read_partial_message 0000000048edf8ad data crc 1063286393 != exp. 228122706
libceph: osd1 (1)192.168.122.1:6843 bad crc/signature
libceph: bad data crc, calculated 57958023, expected 1805382778
libceph: osd2 (2)192.168.122.1:6876 integrity error, bad crc
Introduce rxbounce option to enable use of a bounce buffer when
receiving message data. In particular this is needed if a mapped
image is a Windows VM disk, passed to QEMU. Windows has a system-wide
"dummy" page that may be mapped into the destination buffer (potentially
more than once into the same buffer) by the Windows Memory Manager in
an effort to generate a single large I/O [1][2]. QEMU makes a point of
preserving overlap relationships when cloning I/O vectors, so krbd gets
exposed to this behaviour.

The recv path of secure mode is intertwined with that of crc mode.
While it's slightly more efficient that way (the ciphertext is read
into the destination buffer and decrypted in place, thus avoiding
two potentially heavy memory allocations for the bounce buffer and
the corresponding sg array), it isn't really amenable to changes.
Sacrifice that edge and align with the send path which always uses
a full-sized bounce buffer (currently there is no other way -- if
the kernel crypto API ever grows support for streaming (piecewise)
en/decryption for GCM [1], we would be able to easily take advantage
of that on both sides).

Commit c2426d2ad5027 ("ima: added support for new kernel cmdline parameter
ima_template_fmt") introduced an additional check on the ima_template
variable to avoid multiple template selection.
Unfortunately, ima_template could be also set by the setup function of the
ima_hash= parameter, when it calls ima_template_desc_current(). This causes
attempts to choose a new template with ima_template= or with
ima_template_fmt=, after ima_hash=, to be ignored.
Achieve the goal of the commit mentioned with the new static variable
template_setup_done, so that template selection requests after ima_hash=
are not ignored.
Finally, call ima_init_template_list(), if not already done, to initialize
the list of templates before lookup_template_desc() is called.

The change of sizeof(struct smc_diag_linkinfo) by commit 79d39fc503b4
("net/smc: Add netlink net namespace support") introduced an ABI
regression: since struct smc_diag_lgrinfo contains an object of
type "struct smc_diag_linkinfo", offset of all subsequent members
of struct smc_diag_lgrinfo was changed by that change.
As result, applications compiled with the old version
of struct smc_diag_linkinfo will receive garbage in
struct smc_diag_lgrinfo.role if the kernel implements
this new version of struct smc_diag_linkinfo.
Fix this regression by reverting the part of commit 79d39fc503b4 that
changes struct smc_diag_linkinfo. After all, there is SMC_GEN_NETLINK
interface which is good enough, so there is probably no need to touch
the smc_diag ABI in the first place.
