We don't need to (and shouldn't) initialize the spinlock
during HW restart that was already initialized, so move
that into the correct if block. Since then we have two
consecutive if statements with the same (though inverted)
condition, unify those as well.

There are some assertions in the STA removal code that can
fail, and in that case we may leak memory since we skip
the freeing.
Fix this by freeing the dup_data earlier in the function,
we already have a check for when we free the station, and
this we don't need to do it with and without MLD API, so
it's a win all around.

Core
----
- Introduce a config option to tweak MAX_SKB_FRAGS. Increasing the
default value allows for better BIG TCP performances.
- Reduce compound page head access for zero-copy data transfers.
- RPS/RFS improvements, avoiding unneeded NET_RX_SOFTIRQ when possible.
- Threaded NAPI improvements, adding defer skb free support and unneeded
softirq avoidance.
- Address dst_entry reference count scalability issues, via false
sharing avoidance and optimize refcount tracking.
- Add lockless accesses annotation to sk_err[_soft].
- Optimize again the skb struct layout.
- Extends the skb drop reasons to make it usable by multiple
subsystems.
- Better const qualifier awareness for socket casts.
BPF
---
- Add skb and XDP typed dynptrs which allow BPF programs for more
ergonomic and less brittle iteration through data and variable-sized
accesses.
- Add a new BPF netfilter program type and minimal support to hook
BPF programs to netfilter hooks such as prerouting or forward.
- Add more precise memory usage reporting for all BPF map types.
- Adds support for using {FOU,GUE} encap with an ipip device operating
in collect_md mode and add a set of BPF kfuncs for controlling encap
params.
- Allow BPF programs to detect at load time whether a particular kfunc
exists or not, and also add support for this in light skeleton.
- Bigger batch of BPF verifier improvements to prepare for upcoming BPF
open-coded iterators allowing for less restrictive looping capabilities.
- Rework RCU enforcement in the verifier, add kptr_rcu and enforce BPF
programs to NULL-check before passing such pointers into kfunc.
- Add support for kptrs in percpu hashmaps, percpu LRU hashmaps and in
local storage maps.
- Enable RCU semantics for task BPF kptrs and allow referenced kptr
tasks to be stored in BPF maps.
- Add support for refcounted local kptrs to the verifier for allowing
shared ownership, useful for adding a node to both the BPF list and
rbtree.
- Add BPF verifier support for ST instructions in convert_ctx_access()
which will help new -mcpu=v4 clang flag to start emitting them.
- Add ARM32 USDT support to libbpf.
- Improve bpftool's visual program dump which produces the control
flow graph in a DOT format by adding C source inline annotations.
Protocols
---------
- IPv4: Allow adding to IPv4 address a 'protocol' tag. Such value
indicates the provenance of the IP address.
- IPv6: optimize route lookup, dropping unneeded R/W lock acquisition.
- Add the handshake upcall mechanism, allowing the user-space
to implement generic TLS handshake on kernel's behalf.
- Bridge: support per-{Port, VLAN} neighbor suppression, increasing
resilience to nodes failures.
- SCTP: add support for Fair Capacity and Weighted Fair Queueing
schedulers.
- MPTCP: delay first subflow allocation up to its first usage. This
will allow for later better LSM interaction.
- xfrm: Remove inner/outer modes from input/output path. These are
not needed anymore.
- WiFi:
- reduced neighbor report (RNR) handling for AP mode
- HW timestamping support
- support for randomized auth/deauth TA for PASN privacy
- per-link debugfs for multi-link
- TC offload support for mac80211 drivers
- mac80211 mesh fast-xmit and fast-rx support
- enable Wi-Fi 7 (EHT) mesh support
Netfilter
---------
- Add nf_tables 'brouting' support, to force a packet to be routed
instead of being bridged.
- Update bridge netfilter and ovs conntrack helpers to handle
IPv6 Jumbo packets properly, i.e. fetch the packet length
from hop-by-hop extension header. This is needed for BIT TCP
support.
- The iptables 32bit compat interface isn't compiled in by default
anymore.
- Move ip(6)tables builtin icmp matches to the udptcp one.
This has the advantage that icmp/icmpv6 match doesn't load the
iptables/ip6tables modules anymore when iptables-nft is used.
- Extended netlink error report for netdevice in flowtables and
netdev/chains. Allow for incrementally add/delete devices to netdev
basechain. Allow to create netdev chain without device.
Driver API
----------
- Remove redundant Device Control Error Reporting Enable, as PCI core
has already error reporting enabled at enumeration time.
- Move Multicast DB netlink handlers to core, allowing devices other
then bridge to use them.
- Allow the page_pool to directly recycle the pages from safely
localized NAPI.
- Implement lockless TX queue stop/wake combo macros, allowing for
further code de-duplication and sanitization.
- Add YNL support for user headers and struct attrs.
- Add partial YNL specification for devlink.
- Add partial YNL specification for ethtool.
- Add tc-mqprio and tc-taprio support for preemptible traffic classes.
- Add tx push buf len param to ethtool, specifies the maximum number
of bytes of a transmitted packet a driver can push directly to the
underlying device.
- Add basic LED support for switch/phy.
- Add NAPI documentation, stop relaying on external links.
- Convert dsa_master_ioctl() to netdev notifier. This is a preparatory
work to make the hardware timestamping layer selectable by user
space.
- Add transceiver support and improve the error messages for CAN-FD
controllers.

When CSME takes ownership, the driver sets RFKILL on, and this
triggers driver unload and sending the confirmation SAP message.
However, when IWL_MVM_MEI_REPORT_RFKILL is set, RFKILL was not
reported and as a result, the driver did not confirm the ownership
transition. Fix it.

When mei filtered scan is performed, it must find the AP on the first
scan, otherwise CSME will take the ownership of the NIC.
Make this scan more aggressive by scanning the channel the AP is
supposed to be on (as reported by CSME) several times.

When CSME is connected and has link protection set, the driver must
connect to the same AP CSME is connected to.
When in link protection, modify scan request parameters to include
only the channel of the AP CSME is connected to and scan for the
same SSID. In addition, filter the scan results to include only
results from the same AP. This will make sure the driver will connect
to the same AP and will do it fast enough to keep the session alive.

The RADA/firmware collaborate on MIC stripping in the following
way:
- the firmware fills the IWL_RX_MPDU_MFLG1_MIC_CRC_LEN_MASK
value for how many words need to be removed at the end of
the frame, CRC and, if decryption was done, MIC
- if the RADA is active, it will
- remove that much from the end of the frame
- zero the value in IWL_RX_MPDU_MFLG1_MIC_CRC_LEN_MASK
As a consequence, the only thing the driver should need to do
is to
- unconditionally tell mac80211 that the MIC was removed
if decryption was already done
- remove as much as IWL_RX_MPDU_MFLG1_MIC_CRC_LEN_MASK says
at the end of the frame, since either RADA did it and then
the value is 0, or RADA was disabled and then the value is
whatever should be removed to strip both CRC & MIC
However, all this code was historically grown and getting a
bit confused. Originally, we were indicating that the MIC was
not stripped, which is the version of the code upstreamed in
commit 780e87c29e ("iwlwifi: mvm: add 9000 series RX processing")
which indicated RX_FLAG_DECRYPTED in iwl_mvm_rx_crypto().
We later had a commit to change that to also indicate that the
MIC was stripped, adding RX_FLAG_MIC_STRIPPED. However, this was
then "fixed" later to only do that conditionally on RADA being
enabled, since otherwise RADA didn't strip the MIC bytes yet.
At the time, we were also always including the FCS if the RADA
was not enabled, so that was still broken wrt. the FCS if the
RADA isn't enabled - but that's a pretty rare case. Notably
though, it does happen for management frames, where we do need
to remove the MIC and CRC but the RADA is disabled.
Later, in commit 40a0b38d7a ("iwlwifi: mvm: Fix calculation of
frame length"), we changed this again, upstream this was just a
single commit, but internally it was split into first the correct
commit and then an additional fix that reduced the number of bytes
that are removed by crypt_len. Note that this is clearly wrong
since crypt_len indicates the length of the PN header (always 8),
not the length of the MIC (8 or 16 depending on algorithm).
However, this additional fix mostly canceled the other bugs,
apart from the confusion about the size of the MIC.
To fix this correctly, remove all those additional workarounds.
We really should always indicate to mac80211 the MIC was stripped
(it cannot use it anyway if decryption was already done), and also
always actually remove it and the CRC regardless of the RADA being
enabled or not. That's simple though, the value indicated in the
metadata is zeroed by the RADA if it's enabled and used the value,
so there's no need to check if it's enabled or not.
Notably then, this fixes the MIC size confusion, letting us receive
GCMP-256 encrypted management frames correctly that would otherwise
be reported to mac80211 8 bytes too short since the RADA is turned
off for them, crypt_len is 8, but the MIC size is 16, so when we do
the adjustment based on IWL_RX_MPDU_MFLG1_MIC_CRC_LEN_MASK (which
indicates 20 bytes to remove) we remove 12 bytes but indicate then
to mac80211 the MIC is still present, so mac80211 again removes the
MIC of 16 bytes, for an overall removal of 28 rather than 20 bytes.

When we first add the STA before sending an authentication
frame this is false. However, in some cases such as FT or
certainly in MLO link switch scenarios, it will be true.
If it happens to be true, it causes a firmware assert (in
LMAC, 0x2528), because the same bit is used by the firmware
for tracking this setting as well as for tracking if the
management key has been installed, and then we get this
assert from the firmware when installing the MFP key as it
thinks it has already been installed.
Remove the setting for now, until the firmware disentangles
the two. We should be able to set it, in fact we should be
setting it speculatively before authentication/association,
to avoid processing management frames that should have been
protected/encrypted before the key is set.

This field is used only for host TLC, so it can reside inside
the corresponding lq_sta struct. Also, TLC lq_sta is cleared
in iwl_mvm_rs_rate_init() upon association, but max_agg_bufsize
is set earlier in iwl_mvm_sta_init(). Thus, place this field
in the persistent part of lq_sta to retain its value.

When we remove the station, we call iwl_mvm_sta_del() which
returns true if we cannot remove it from the firmware yet,
which happens if this is the station ID for the AP station
that's still used because the MAC is still associated.
However, we still must free the link data as the station is
only kept alive in the firmware, in mac80211 and driver the
data structures are destroyed.
To fix that, we need to make iwl_mvm_mld_free_sta_link()
track whether or not the station is still alive in FW, as
otherwise we might reuse the station ID in the meantime and
iwl_mvm_mld_rm_sta_from_fw() would reject the later delete
from the firmware. Add an argument to it for that. Then we
can use the return value of iwl_mvm_sta_del() for that to
fix the issue, and call iwl_mvm_mld_rm_sta_from_fw() only
if we need to not keep the station in FW.

This bitmap indicates what fields of the cmd got changed.
A field will be ignored by the FW if the corresponding flag wasn't set.
There are a few cases in which we currently set the wrong bits when
sending this cmd, which caused FW asserts. Fix this by setting the
correct bits in each case.

except for the commands that are being sent during this flows.
Instead of checking each time before calling these floews
what API we use and then call the correct function, call always the old

WE can't mix between the new MLD API and the old API.
I.e. - we can't send one of the new cmds and then one of the old ones.
This will cause a FW assert. So we need an indication what API should be
used. We use the new API if:
1. FW supports it
2. We are registered to mac80211 with the new MLD ops

In MLO, some fields of iwl_mvm_vif should be defined in the
context of a link. Define a separate structure for these fields and
add a deflink object to hold it as part of iwl_mvm_vif. Non-MLO legacy
code will use only deflink object while MLO related code will use the
corresponding link from the link array.
It follows the strategy applied in mac80211 for introducing MLO
changes.
The below spatch takes care of updating all driver code to access
fields separated into MLD specific data structure via deflink (need
to convert all references to the fields listed in var to deflink.var

There is a 64-bit division in iwl_mvm_get_crosstimestamp_fw(), which
results in a link failure when building 32-bit architectures with clang:
ld.lld: error: undefined symbol: __udivdi3
>>> referenced by ptp.c
>>> drivers/net/wireless/intel/iwlwifi/mvm/ptp.o:(iwl_mvm_phc_get_crosstimestamp) in archive vmlinux.a
GCC has optimizations for division by a constant that clang does not
implement, so this issue is not visible when building with GCC.
Use the 64-bit division helper div_u64(), which takes a u64 dividend and
u32 divisor, which matches this situation and prevents the emission of a
libcall for the division.

We used to send a MAC CTXT cmd to ask the FW to not pass MCAST frames
if we're associated but not authorized, because we don't have the
keys in that stage, and after authorization - we sent the cmd again
to ask the FW to pass MCAST, as we have the keys now.
The patch linked below was changing this strategy to always allow
MCAST frames, and if we're not authorized - the driver will drop them.
But we're still sending the MAC CTXT cmd after deaouthorization even
though we don't tell the FW to not pass MCAST frames anymore.
Basically we don't tell the FW anything new with this cmd.
Fix this by not sending MAC CTXT command after deauthorization.
For authorization we're sending the cmd to configure other changes too,
so keep it.

iwl_mvm_get_sync_time() reads the gp2 from the device and then
reads the system clock. Since the two reads are not done atomically,
unexpected delays may happen between the two reads (e.g. context
switch) which make it inaccurate.
In order to improve the accuracy of the cross timestamp, call

For TM/FTM frames, report the hardware timestamps reported by the
fw as part of the RX/TX status. Since the fw reports the timestamps
in a dedicated notification (and not as part of the RX/TX status),
hold the frame until the fw timestamps notification is received.
Timestamping is enabled when a station is connected and disabled
when disconnected. For AP interface, only the first station will

Refactor MAC_CONTEXT_CMD sending flow:
1. As the new MLD API is introduced, there are some common fields in
both the old and new APIs. The MAC_CONTEXT_CMD of the non-MLD API
has common fields with the link and mac commands of the new MLD API.
Put this common parts in functions so it can be used later by the
new MLD API.
2. Use iwl_mvm_mac_ctxt_send_cmd when removing a mac instead of
implementing the same functionality once again.
3. Change the debug print when sending the command to be more specific,
so it will be easy to distinguish later if the old or new mac command
was sent.

In FW restart scenarios, we allocate the queues from the
iwl_mvm_realloc_queues_after_restart() function, but that
is called before we insert the station ID into our map
(mvm->fw_id_to_mac_id).
However, in all cases where we're actually allocating a
queue for a "real" (not bcast, aux, ...) station we have
the sta pointer already, so just pass it along to use it
instead of looking it up.
This fixes an issue where after restart we only allocated
a queue of size 16 (due to the ordering issue described
above), and thus never got good throughput again since no
aggregates could be formed on transmit.

In monitor mode, we try to report the EOF bit on the
first MPDU of an A-MPDU (hardware duplicates this bit
over all MPDUs, so it's only trustable on the first).
However, due to reshuffling in an ealier commit, the
toggle_bit != mvm->ampdu_toggle logic can no longer
work since mvm->ampdu_toggle is now set before this
code runs.
Fix this by tracking the first_subframe status in the
phy data struct and using that instead of checking.

For the old TX API we need the tfd_queue_msk, but for the
new TX API we don't need it here because we add it to the
station later. However, for the new API mvm->snif_queue is
set to IWL_MVM_INVALID_QUEUE == 0xffff, so the BIT() here
is undefined behaviour.
Since we don't need the tfd_queue_msk value for the new TX
API at all, simply fill it in only for the old API.

The thermal zone device structure is exposed to the different drivers
and obviously they access the internals while that should be
restricted to the core thermal code.
In order to self-encapsulate the thermal core code, we need to prevent
the drivers accessing directly the thermal zone structure and provide
accessor functions to deal with.
Use the devdata accessor introduced in the previous patch.
No functional changes intended.

Core
----
- Add dedicated kmem_cache for typical/small skb->head, avoid having
to access struct page at kfree time, and improve memory use.
- Introduce sysctl to set default RPS configuration for new netdevs.
- Define Netlink protocol specification format which can be used
to describe messages used by each family and auto-generate parsers.
Add tools for generating kernel data structures and uAPI headers.
- Expose all net/core sysctls inside netns.
- Remove 4s sleep in netpoll if carrier is instantly detected on boot.
- Add configurable limit of MDB entries per port, and port-vlan.
- Continue populating drop reasons throughout the stack.
- Retire a handful of legacy Qdiscs and classifiers.
Protocols
---------
- Support IPv4 big TCP (TSO frames larger than 64kB).
- Add IP_LOCAL_PORT_RANGE socket option, to control local port range
on socket by socket basis.
- Track and report in procfs number of MPTCP sockets used.
- Support mixing IPv4 and IPv6 flows in the in-kernel MPTCP
path manager.
- IPv6: don't check net.ipv6.route.max_size and rely on garbage
collection to free memory (similarly to IPv4).
- Support Penultimate Segment Pop (PSP) flavor in SRv6 (RFC8986).
- ICMP: add per-rate limit counters.
- Add support for user scanning requests in ieee802154.
- Remove static WEP support.
- Support minimal Wi-Fi 7 Extremely High Throughput (EHT) rate
reporting.
- WiFi 7 EHT channel puncturing support (client & AP).
BPF
---
- Add a rbtree data structure following the "next-gen data structure"
precedent set by recently added linked list, that is, by using
kfunc + kptr instead of adding a new BPF map type.
- Expose XDP hints via kfuncs with initial support for RX hash and
timestamp metadata.
- Add BPF_F_NO_TUNNEL_KEY extension to bpf_skb_set_tunnel_key
to better support decap on GRE tunnel devices not operating
in collect metadata.
- Improve x86 JIT's codegen for PROBE_MEM runtime error checks.
- Remove the need for trace_printk_lock for bpf_trace_printk
and bpf_trace_vprintk helpers.
- Extend libbpf's bpf_tracing.h support for tracing arguments of
kprobes/uprobes and syscall as a special case.
- Significantly reduce the search time for module symbols
by livepatch and BPF.
- Enable cpumasks to be used as kptrs, which is useful for tracing
programs tracking which tasks end up running on which CPUs in
different time intervals.
- Add support for BPF trampoline on s390x and riscv64.
- Add capability to export the XDP features supported by the NIC.
- Add __bpf_kfunc tag for marking kernel functions as kfuncs.
- Add cgroup.memory=nobpf kernel parameter option to disable BPF
memory accounting for container environments.
Netfilter
---------
- Remove the CLUSTERIP target. It has been marked as obsolete
for years, and we still have WARN splats wrt. races of
the out-of-band /proc interface installed by this target.
- Add 'destroy' commands to nf_tables. They are identical to
the existing 'delete' commands, but do not return an error if
the referenced object (set, chain, rule...) did not exist.
Driver API
----------
- Improve cpumask_local_spread() locality to help NICs set the right
IRQ affinity on AMD platforms.
- Separate C22 and C45 MDIO bus transactions more clearly.
- Introduce new DCB table to control DSCP rewrite on egress.
- Support configuration of Physical Layer Collision Avoidance (PLCA)
Reconciliation Sublayer (RS) (802.3cg-2019). Modern version of
shared medium Ethernet.
- Support for MAC Merge layer (IEEE 802.3-2018 clause 99). Allowing
preemption of low priority frames by high priority frames.
- Add support for controlling MACSec offload using netlink SET.
- Rework devlink instance refcounts to allow registration and
de-registration under the instance lock. Split the code into multiple
files, drop some of the unnecessarily granular locks and factor out
common parts of netlink operation handling.
- Add TX frame aggregation parameters (for USB drivers).
- Add a new attr TCA_EXT_WARN_MSG to report TC (offload) warning
messages with notifications for debug.
- Allow offloading of UDP NEW connections via act_ct.
- Add support for per action HW stats in TC.
- Support hardware miss to TC action (continue processing in SW from
a specific point in the action chain).
- Warn if old Wireless Extension user space interface is used with
modern cfg80211/mac80211 drivers. Do not support Wireless Extensions
for Wi-Fi 7 devices at all. Everyone should switch to using nl80211
interface instead.
- Improve the CAN bit timing configuration. Use extack to return error
messages directly to user space, update the SJW handling, including
the definition of a new default value that will benefit CAN-FD
controllers, by increasing their oscillator tolerance.

Merge tag 'net-next-6.3' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next
Pull networking updates from Jakub Kicinski:
"Core:
- Add dedicated kmem_cache for typical/small skb->head, avoid having
to access struct page at kfree time, and improve memory use.
- Introduce sysctl to set default RPS configuration for new netdevs.
- Define Netlink protocol specification format which can be used to
describe messages used by each family and auto-generate parsers.
Add tools for generating kernel data structures and uAPI headers.
- Expose all net/core sysctls inside netns.
- Remove 4s sleep in netpoll if carrier is instantly detected on
boot.
- Add configurable limit of MDB entries per port, and port-vlan.
- Continue populating drop reasons throughout the stack.
- Retire a handful of legacy Qdiscs and classifiers.
Protocols:
- Support IPv4 big TCP (TSO frames larger than 64kB).
- Add IP_LOCAL_PORT_RANGE socket option, to control local port range
on socket by socket basis.
- Track and report in procfs number of MPTCP sockets used.
- Support mixing IPv4 and IPv6 flows in the in-kernel MPTCP path
manager.
- IPv6: don't check net.ipv6.route.max_size and rely on garbage
collection to free memory (similarly to IPv4).
- Support Penultimate Segment Pop (PSP) flavor in SRv6 (RFC8986).
- ICMP: add per-rate limit counters.
- Add support for user scanning requests in ieee802154.
- Remove static WEP support.
- Support minimal Wi-Fi 7 Extremely High Throughput (EHT) rate
reporting.
- WiFi 7 EHT channel puncturing support (client & AP).
BPF:
- Add a rbtree data structure following the "next-gen data structure"
precedent set by recently added linked list, that is, by using
kfunc + kptr instead of adding a new BPF map type.
- Expose XDP hints via kfuncs with initial support for RX hash and
timestamp metadata.
- Add BPF_F_NO_TUNNEL_KEY extension to bpf_skb_set_tunnel_key to
better support decap on GRE tunnel devices not operating in collect
metadata.
- Improve x86 JIT's codegen for PROBE_MEM runtime error checks.
- Remove the need for trace_printk_lock for bpf_trace_printk and
bpf_trace_vprintk helpers.
- Extend libbpf's bpf_tracing.h support for tracing arguments of
kprobes/uprobes and syscall as a special case.
- Significantly reduce the search time for module symbols by
livepatch and BPF.
- Enable cpumasks to be used as kptrs, which is useful for tracing
programs tracking which tasks end up running on which CPUs in
different time intervals.
- Add support for BPF trampoline on s390x and riscv64.
- Add capability to export the XDP features supported by the NIC.
- Add __bpf_kfunc tag for marking kernel functions as kfuncs.
- Add cgroup.memory=nobpf kernel parameter option to disable BPF
memory accounting for container environments.
Netfilter:
- Remove the CLUSTERIP target. It has been marked as obsolete for
years, and we still have WARN splats wrt races of the out-of-band
/proc interface installed by this target.
- Add 'destroy' commands to nf_tables. They are identical to the
existing 'delete' commands, but do not return an error if the
referenced object (set, chain, rule...) did not exist.
Driver API:
- Improve cpumask_local_spread() locality to help NICs set the right
IRQ affinity on AMD platforms.
- Separate C22 and C45 MDIO bus transactions more clearly.
- Introduce new DCB table to control DSCP rewrite on egress.
- Support configuration of Physical Layer Collision Avoidance (PLCA)
Reconciliation Sublayer (RS) (802.3cg-2019). Modern version of
shared medium Ethernet.
- Support for MAC Merge layer (IEEE 802.3-2018 clause 99). Allowing
preemption of low priority frames by high priority frames.
- Add support for controlling MACSec offload using netlink SET.
- Rework devlink instance refcounts to allow registration and
de-registration under the instance lock. Split the code into
multiple files, drop some of the unnecessarily granular locks and
factor out common parts of netlink operation handling.
- Add TX frame aggregation parameters (for USB drivers).
- Add a new attr TCA_EXT_WARN_MSG to report TC (offload) warning
messages with notifications for debug.
- Allow offloading of UDP NEW connections via act_ct.
- Add support for per action HW stats in TC.
- Support hardware miss to TC action (continue processing in SW from
a specific point in the action chain).
- Warn if old Wireless Extension user space interface is used with
modern cfg80211/mac80211 drivers. Do not support Wireless
Extensions for Wi-Fi 7 devices at all. Everyone should switch to
using nl80211 interface instead.
- Improve the CAN bit timing configuration. Use extack to return
error messages directly to user space, update the SJW handling,
including the definition of a new default value that will benefit
CAN-FD controllers, by increasing their oscillator tolerance.

The thermal framework gives the possibility to register the trip
points with the thermal zone. When that is done, no get_trip_* ops are
needed and they can be removed.
The get_trip_temp, get_trip_hyst and get_trip_type are handled by the
get_trip_point().
The set_trip_temp() generic function does some checks which are no
longer needed in the set_trip_point() ops.
Convert ops content logic into generic trip points and register them
with the thermal zone.

Due to several bugs caused by timers being re-armed after they are
shutdown and just before they are freed, a new state of timers was added
called "shutdown". After a timer is set to this state, then it can no
longer be re-armed.
The following script was run to find all the trivial locations where
del_timer() or del_timer_sync() is called in the same function that the
object holding the timer is freed. It also ignores any locations where
the timer->function is modified between the del_timer*() and the free(),
as that is not considered a "trivial" case.
This was created by using a coccinelle script and the following
commands:
$ cat timer.cocci
@@
expression ptr, slab;
identifier timer, rfield;
@@
(
- del_timer(&ptr->timer);
+ timer_shutdown(&ptr->timer);
|
- del_timer_sync(&ptr->timer);
+ timer_shutdown_sync(&ptr->timer);
)
... when strict
when != ptr->timer
(
kfree_rcu(ptr, rfield);

kmem_cache_free(slab, ptr);

kfree(ptr);

The CSR_HW_IF_CONFIG_REG register is no longer in use from
IWL_DEVICE_FAMILY_AX210 and on.
This register uses now for CSR_CTXT_INFO_BOOT_CTRL
which has a different meaning and a different format.
Currently we're writing to the register according to
CSR_HW_IF_CONFIG_REGs format, regardless to the device family.
This causes to miss-interpretation of the register value, as it is
parsed according to CSR_CTXT_INFO_BOOT_CTRLs format for devices
families >= IWL_DEVICE_FAMILY_AX210.
Fix this by writing to the register according to the old format
only for the relevant hardware.

To move the list iterator variable into the list_for_each_entry_*()
macro in the future it should be avoided to use the list iterator
variable after the loop body.
To *never* use the list iterator variable after the loop it was
concluded to use a separate iterator variable instead of a
found boolean [1].
This removes the need to use a found variable and simply checking if
the variable was set, can determine if the break/goto was hit.
While at it, stop using the unnecessary _safe() variant.

In order to support MLD, the key API is also changing to have
station masks instead of just the station ID etc. Change the
driver to support this, and add the new code in a new file so
it's more clearly separated.
For now this isn't separated at the mac80211 ops level, which
we wanted to do, but we're calling these functions in a place
when pre-start keys are installed in iwl_mvm_start_ap_ibss(),
and the function has some glue logic to mac80211. We may want
to change that later.

In some rare occasions, the firmware may let some frames with invalid

It is possible that CSME will try to take ownership while the driver
is stopping. In this case, if the CSME takes ownership message arrives
after the driver started unregistering, the iwl_mei_cache->ops is
already invalid, so the host will not answer with the ownership
confirmed message.
Similarly, if the take ownership message arrived after the mac was
stopped or when iwl_mvm_up() failed, setting rfkill will not trigger
sending the confirm message. As a result, CSME will not take
ownership, which will result in a disconnection.
Fix it by sending the ownership confirmed message immediately in such
cases.

Pull more random number generator updates from Jason Donenfeld:
"This time with some large scale treewide cleanups.
The intent of this pull is to clean up the way callers fetch random
integers. The current rules for doing this right are:
- If you want a secure or an insecure random u64, use get_random_u64()
- If you want a secure or an insecure random u32, use get_random_u32()
The old function prandom_u32() has been deprecated for a while
now and is just a wrapper around get_random_u32(). Same for
get_random_int().
- If you want a secure or an insecure random u16, use get_random_u16()
- If you want a secure or an insecure random u8, use get_random_u8()
- If you want secure or insecure random bytes, use get_random_bytes().
The old function prandom_bytes() has been deprecated for a while
now and has long been a wrapper around get_random_bytes()
- If you want a non-uniform random u32, u16, or u8 bounded by a
certain open interval maximum, use prandom_u32_max()
I say "non-uniform", because it doesn't do any rejection sampling
or divisions. Hence, it stays within the prandom_*() namespace, not
the get_random_*() namespace.
I'm currently investigating a "uniform" function for 6.2. We'll see
what comes of that.
By applying these rules uniformly, we get several benefits:
- By using prandom_u32_max() with an upper-bound that the compiler
can prove at compile-time is ≤65536 or ≤256, internally
get_random_u16() or get_random_u8() is used, which wastes fewer
batched random bytes, and hence has higher throughput.
- By using prandom_u32_max() instead of %, when the upper-bound is
not a constant, division is still avoided, because
prandom_u32_max() uses a faster multiplication-based trick instead.
- By using get_random_u16() or get_random_u8() in cases where the
return value is intended to indeed be a u16 or a u8, we waste fewer
batched random bytes, and hence have higher throughput.
This series was originally done by hand while I was on an airplane
without Internet. Later, Kees and I worked on retroactively figuring
out what could be done with Coccinelle and what had to be done
manually, and then we split things up based on that.
So while this touches a lot of files, the actual amount of code that's
hand fiddled is comfortably small"

So, it is necessary to extend the applied solution with commit 14a3aacf51
("iwlwifi: mvm: fix double list_add at iwl_mvm_mac_wake_tx_queue")
to all other cases where the station queues are invalidated and the related
lists are not emptied. Because, otherwise as before, if some new element is
added later to the list in iwl_mvm_mac_wake_tx_queue, it can match with the
old one and produce the same commented BUG.
That is, in order to avoid this problem completely, we must also remove the
related lists for the other cases when station queues are invalidated.

In preparation for reducing the use of ksize(), explicitly track the
size of scan_cmd allocations. This also allows for noticing if the scan
size changes unexpectedly. Note that using ksize() was already incorrect
here, in the sense that ksize() would not match the actual allocation
size, which would trigger future run-time allocation bounds checking.
(In other words, memset() may know how large scan_cmd was allocated for,
but ksize() will return the upper bounds of the actually allocated memory,
causing a run-time warning about an overflow.)

Currently, when resuming from d3 during which an assert was thrown,
the resume flow skips the iteration over active interfaces
preventing the sta to reconnect to the ap.

We have recently enabled resume flow based on notifications.
These notifications are sent by the FW when completing the resume flow.
From IWL_DEVICE_FAMILY_AX210 the resume flow is triggered by the
transport layer on iwl_trans_d3_resume.
On IWL_DEVICE_FAMILY_22000 and earlier we trigger the resume flow by
sending the D0I3 command.
Currently, we are waiting for the notifications before sending the
command, the notifications won't be sent by the FW since there is no
resume trigger to piggyback on.
Send the command before starting the wait flow to fix it.

The wowlan info notification is quite big.
(~750 bytes without the wake packet itself).
The max FW notification size is ~2K.
There might be cases where the wake packet gets truncated because of
this limit.
Separating the wake packet from the wowlan info notification allows us to
get more data without trimming it.
Note: we currently limit the wake packet to 1600 bytes.

IMR (Isolated Memory Regions) is a mechanism to protect memory regions
from unwarranted access by agents in the system that should not have access
to that memory.
When IMR is enabled, pages in the DRAM will be located within the IMR
memory space, accessible only by the device.
As a side effect, during S4 (a.k.a hibernate) the IMR memory space
is not retained.
While the DRAM is saved to the disk and restored by the OS upon resume,
the IMR, which is hidden from the OS neither saved upon suspend nor
restored upon resume.
As a consequence of the above, it turned out that commands cannot
be sent as part of the resume flow, and so after ending
d3 the FW needs to use notifications instead of cmd-resp.
The resume flow becomes asynchronous, with a series
of notifications, starting with wowlan_info_notif, through
wowlan_pkt_notif and complete the resume flow by d3_end_notif.
This patch adds the support for wowlan info notification.
The wake packet has been removed from the wowlan info struct
and will be handled in a dedicated notification.

There's a bunch of duplicated code in the normal data RX and
the no-data RX paths, refactor that.
Note that we're evidently not implementing the 6 GHz band in
the no-data path correctly, need to fix that in firmware
first. Also, we were setting the NSS differently, keep doing
that, but just override the previous values.
Note also that we used to drop frames with bad rate data, to
simplify that just report rate 0 and continue.

The A-MSDU data needs to be stored per-link and aggregated into a single
value for the station. Add a new struct ieee_80211_sta_aggregates in
order to store this data and a new function
ieee80211_sta_recalc_aggregates to update the current data for the STA.
Note that in the non MLO case the pointer in ieee80211_sta will directly
reference the data in deflink.agg, which means that recalculation may be
skipped in that case.

The previous format specifier `%hhu` describes a u8 but our arguments
are wider than this which means bits are potentially being lost.
Variadic functions (printf-like) undergo default argument promotion.
Documentation/core-api/printk-formats.rst specifically recommends using
the promoted-to-type's format flag.
As per C11 6.3.1.1:
(https://www.open-std.org/jtc1/sc22/wg14/www/docs/n1548.pdf) `If an int
can represent all values of the original type ..., the value is
converted to an int; otherwise, it is converted to an unsigned int.
These are called the integer promotions.` Thus it makes sense to change
`%hhu` to `%d` for both instances of the warning.

Currently in mac80211 each STA object is represented
using sta_info datastructure with the associated
STA specific information and drivers access ieee80211_sta
part of it.
With MLO (Multi Link Operation) support being added
in 802.11be standard, though the association is logically
with a single Multi Link capable STA, at the physical level
communication can happen via different advertised
links (uniquely identified by Channel, operating class,
BSSID) and hence the need to handle multiple link
STA parameters within a composite sta_info object
called the MLD STA. The different link STA part of
MLD STA are identified using the link address which can
be same or different as the MLD STA address and unique
link id based on the link vif.
To support extension of such a model, the sta_info
datastructure is modified to hold multiple link STA
objects with link specific params currently within
sta_info moved to this new structure. Similarly this is
done for ieee80211_sta as well which will be accessed
within mac80211 as well as by drivers, hence trivial
driver changes are expected to support this.
For current non MLO supported drivers, only one link STA
is present and link information is accessed via 'deflink'
member.
For MLO drivers, we still need to define the APIs etc. to
get the correct link ID and access the correct part of
the station info.
Currently in mac80211, all link STA info are accessed directly
via deflink. These will be updated to access via link pointers
indexed by link id with MLO support patches, with link id
being 0 for non MLO supported cases.
Except for couple of macro related changes, below spatch takes
care of updating mac80211 and driver code to access to the
link STA info via deflink.

Newer firmware versions will support a new queue allocation
command, in order to deal with MLD where multiple stations
are used for a single queue. Add support for the new command.
This requires some refactoring of the queue allocation API,
which now gets
- the station mask instead of the station ID
- the flags without the "enable" flag, since that's no longer
used in the new API
Additionally, this new API now requires that we remove queues
before removing a station, the firmware will no longer do that
internally. Also add support for that.

Thus, when scan is requested while there is an active P2P GO
and low latency is asserted:
- Ask the FW scan logic to respect the P2P GO activity during the
scheduling of the scan operation to minimize the impact on the
throughput and latency.
- Force scan to perform EBS before starting the scan to reduce the

collocated APs obtained during scan on legacy bands, and otherwise
should not be scanned unless specifically requested so (as there are
relatively many non PSC channels, scanning them passively is time consuming

Thus, modify the scan logic to avoid passively scanning PSC channels

("iwlwifi: dbg: Mark ucode tlv data as const") propagating the
(const) type qualifier for ucode based tlv data to avoid having
the impression that it is writeable.
The other part of the change preserves the (const) type qualifier
over casts and function calls where it was previously lost.
Both changes are needed to avoid compile time errors on system with
more strict error settings, in this case found with clang on FreeBSD.

In order to de-const variables simply casting through (void *) is
not enough: "cast from 'const .. *' to 'void *' drops const qualifier".
Cast through (uintptr_t) as well [1] to make this compile on systems
with more strict requirements.
In addition passing const void *data to dma_map_single() also
drops the (const) qualifier. De-constify on variable on assignment
which may be overwritten later. In either case the (void *) cast
to dma_map_single() is not needed (anymore) either.

The order of arguments for iwl_cmd_id() is confusing, and the
version is always 0 and thus a useless argument. Prefer the
WIDE_ID() macro (which needs to be a macro due to use in switch
cases etc.) over the iwl_cmd_id() function.
Obviously done with spatch:

-iwl_cmd_id(C, G, 0)

Since FW is now in charge of timing the channel switch, there is no need
to send the add/modify/remove time event command to fw with every (e)CSA
element.
However, the driver needs to cancel the channel switch if the CS start
notification arrives and it does not know about an ongoing channel switch.

The recent fix for NULL sta in iwl_mvm_get_tx_rate() still has a call
of iwl_mvm_sta_from_mac80211() that may be called with NULL sta.
Although this practically only points to the address and the actual
access doesn't happen due to the conditional evaluation at a later
point, it looks a bit flaky.
This patch drops the temporary variable above and evaluates
iwm_mvm_sta_from_mac80211() directly for avoiding confusions.

There's currently only one driver that reports CHECKSUM_COMPLETE,
that is iwlwifi. The current hardware there calculates checksum
after the SNAP header, but only RFC 1042 (and some other cases,
but replicating the exact hardware logic for corner cases in the
driver seemed awkward.)
Newer generations of hardware will checksum _including_ the SNAP,
which makes things easier.
To handle that, simply always assume the checksum _includes_ the
SNAP header, which this patch does, requiring to first add it
for older iwlwifi hardware, and then remove it again later on
conversion.
Alternatively, we could have:
1) Always assumed the checksum starts _after_ the SNAP header;
the problem with this is that we'd have to replace the exact
"what is the SNAP" check in iwlwifi that cfg80211 has.
2) Made it configurable with some flag, but that seemed like too
much complexity.

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

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.

Commit d068ca2ae2 ("codel: split into multiple files") moved all
Qdisc-related code to codel_qdisc.h, move the include of pkt_sched.h
as well.
This is similar to the previous commit, although we don't care as
much about incremental builds after pkt_sched.h was touched itself
it is included by net/sch_generic.h which is modified ~20 times
a year.
This decreases the incremental build size after touching pkt_sched.h
from 1592 to 617 objects.
Fix unmasked missing includes in WiFi drivers.

When IWL_UCODE_TLV_CAPA_SESSION_PROT_CMD is set, removing a time event
always tries to cancel session protection. However, AUX ROC does
not use session protection so it was never removed. As a result,
if the driver tries to allocate another AUX ROC event right after
cancelling the first one, it will fail with a warning.
In addition, the time event data passed to iwl_mvm_remove_aux_roc_te()

The 6GHz passive scan is performed only once every 50 minutes.
However, in case of suspend/resume, the regulatory information
is reset, so 6GHz channels may become disabled.
Fix it by performing a 6GHz passive scan within 60 seconds after
suspend/resume even if the 50 minutes timeout did not expire yet.

In case of a conflict between BIOS version and FW
version of the PPAG table - the values arrive in the FW in the wrong
places. This happens because we're storing the table in different
structures depending on the BIOS version, not on the FW version,
and so the FW doesn't get what it expect to.
Always store the table in a v2 structure (which is a superset
of v1 and v0).
Also store the table in a structured way and in it's own structure,
rather then storing it in the ppag command structure, similarly to
the WRDS, EWRD and WGDS tables.

With the introduction of 6GHz channels the scan guard timeout should
be adjusted to account for the following extreme case:
- All 6GHz channels are scanned passively: 58 channels.
- The scan is fragmented with the following parameters: 3 fragments,
95 TUs suspend time, 44 TUs maximal out of channel time.
The above would result with scan time of more than 24 seconds. Thus,
set the timeout to 30 seconds.

define the necessary data structures etc. Rename "soc.h" to

We have a MAC component (which is inside the SoC) and it has several
different HW steps. 3 bits used to be enough but now we need 4-bits
to represent all the different steps.
Properly support 4-bits in the MAC step value by refactoring all the
current handling of the MAC step/dash.
Already from family 8000 and up the dash (bits 0-1) no longer exists
and the step (until 8000 bits 2-3) consists of the dash bits as well.
To do this remove the CSR_HW_REV_STEP and the CSR_HW_REV_DASH
macros, replace them with CSR_HW_REV_STEP_DASH and add hw_rev_step
into the trans struct.
In addition remove the CSR_HW_IF_CONFIG_REG_MSK_MAC_STEP and
CSR_HW_IF_CONFIG_REG_MSK_MAC_DASH macros and create a new macro
combining the 2 (this way we don't need shifting or anything else.)

If userspace installs a lot of multicast groups very quickly, then
we may run out of command queue space as we send the updates in an
asynchronous fashion (due to locking concerns), and the CPU can
create them faster than the firmware can process them. This is true
even when mac80211 has a work struct that gets scheduled.
Fix this by synchronizing with the firmware after sending all those
commands - outside of the iteration we can send a synchronous echo
command that just has the effect of the CPU waiting for the prior
asynchronous commands to finish. This also will cause fewer of the
commands to be sent to the firmware overall, because the work will
only run once when rescheduled multiple times while it's running.

If we happen to decide an NSSN queue sync (IWL_MVM_RXQ_NSSN_SYNC)
for some remaining packets that are still on the queue, but just
after we've decided to do a delBA (which causes its own queues
sync with IWL_MVM_RXQ_NOTIF_DEL_BA) we can end up with a sequence
of events like this:
CPU 1 CPU 2
remove BA session with baid N
send IWL_MVM_RXQ_NOTIF_DEL_BA
send IWL_MVM_RXQ_NSSN_SYNC
get IWL_MVM_RXQ_NOTIF_DEL_BA
get IWL_MVM_RXQ_NOTIF_DEL_BA
get IWL_MVM_RXQ_NSSN_SYNC
complete IWL_MVM_RXQ_NOTIF_DEL_BA
remove N from baid_map[]
get IWL_MVM_RXQ_NSSN_SYNC
WARN_ON(!baid_map[N])
Thus, there's a race that leads in hitting the WARN_ON, but more
importantly, it's a race that potentially even results in a new
aggregation session getting assigned to baid N.
To fix this, remove the WARN_ON() in the NSSN_SYNC case, we can't
completely protect against hitting this case, so we shouldn't be
warning. However, guard ourselves against BAID reuse by doing yet
another round of queue synchronization after the entry is removed
from the baid_map, so that it cannot be reused with any in-flight
IWL_MVM_RXQ_NSSN_SYNC messages.

In some very rare cases the init flow may fail. In many cases, this is
recoverable, so we can retry. Implement a loop to retry two more times
after the first attempt failed.
This can happen in two different situations, namely during probe and
during mac80211 start. For the first case, a simple loop is enough.
For the second case, we need to add a flag to prevent mac80211 from
trying to restart it as well, leaving full control with the driver.

When we receive an association response, a significant amount
of time might have passed since we sent the corresponding
association request (mac80211 will wait up to 500ms for the TX

the time event is touched only when we send the assoc request,

Trying to convert from one firmware data representation to the
next version is getting tedious and error-prone, and doesn't
lend itself well to new APIs being added. Additionally, the
version 11 of the API as defined in the driver doesn't even
exist in the firmware.
Instead of converting to a newer firmware version of the data,
convert to an internal representation. This takes a bit more
space because the TKIP/AES counters etc. must be kept twice,
their representation is different and we don't know which of
the ones it is until later, but this is just a temporary use
of memory, and the code is clearer this way.

When auth/assoc completes, we should remove session protection,
except when association is successful, where we need it until a
beacon is received from the AP.
In particular, in the case of assoc comeback, currently the session
protection event just times out, leading to confusing messages:
wlan0: 42:00:00:00:00:00 rejected association temporarily; comeback duration 1000 TU (1024 ms)
iwlwifi 0000:00:00.0: Not associated and the session protection is over already...
wlan0: Connection to AP 42:00:00:00:00:00 lost
wlan0: associate with 42:00:00:00:00:00 (try 2/3)
mac80211 never does anything on the "Connection ... lost" as it's
not even connected.
Removing the session protection when it's no longer needed removes
those confusing messages and lets the device do other things in the
allocated time.

In firmware dumps, currently all kinds of key material may be
included, e.g. in host commands (if firmware crashes during the
processing of a key-related command) or in the TX FIFO(s) if
we have been using in-TX-command key material.
Additionally, some firmware versions will advertise sections
of their internal data to not dump, due to them containing some
sensitive data.
Add some infrastructure to allow scrubbing this data out, as
dependent on the opmode's idea of what will need to be done.

Instead, check the IWL_RX_MPDU_STATUS_KEY_VALID bit that

that's set but we get invalid MIC/replay use the key ID
from the frame to look up the key and notify mac80211 of

When P2P roc is removed, the IWL_MVM_STATUS_NEED_FLUSH_P2P bit is set
to indicate to iwl_mvm_roc_done_wk() that the removed roc is a P2P
one, so it will flush the broadcast station and not the aux station.
However, since setting this bit and scheduling the worker is done
in roc ended flow as well as in case the roc is removed, there is
a race where the worker has already started running (but did not
test this bit yet) and then it is scheduled again. In this case,
the first run of the worker will clear this bit, and thus the second
run will find it already cleared and will try to flush and remove
the aux station by mistake.
Fix it by scheduling the worker only if this bit is not yet set. In
case this bit is already set, the worker is either running or
scheduled, so there is no need to re-schedule it.

queue numbers are just sequentially assigned 0, 1, 2, ...
Prior to TVQM, in DQA, there were some statically allocated
queue numbers:
* IWL_MVM_DQA_AUX_QUEUE == 1,
* both IWL_MVM_DQA_INJECT_MONITOR_QUEUE and
IWL_MVM_DQA_P2P_DEVICE_QUEUE == 2, and
* IWL_MVM_DQA_AP_PROBE_RESP_QUEUE == 9.
Now, these values are assigned to the members mvm->aux_queue,
mvm->snif_queue, mvm->probe_queue and mvm->p2p_dev_queue by
default. Normally, this doesn't really matter, and if TVQM is
in fact available we override them to the real values after
allocating a queue for use there.
However, this allocation doesn't always happen. For example,
for mvm->p2p_dev_queue (== 2) it only happens when the P2P
Device interface is started, if any. If it's not started, the
value in mvm->p2p_dev_queue remains 2. This wouldn't really
matter all that much if it weren't for iwl_mvm_is_static_queue()
which checks a queue number against one of those four static
numbers.
Now, if no P2P Device or monitor interface is added then queue
2 may be dynamically allocated, yet alias mvm->p2p_dev_queue or
mvm->snif_queue, and thus iwl_mvm_is_static_queue() erroneously
returns true for it. If it then gets full, all interface queues
are stopped, instead of just backpressuring against the one TXQ
that's really the only affected one.
This clearly can lead to issues, as everything is stopped even
if just a single TXQ filled its corresponding HW queue, if it
happens to have an appropriate number (2 or 9, AUX is always
reassigned.) Due to a mac80211 bug, this also led to a situation
in which the queues remained stopped across a deauthentication
and then attempts to connect to a new AP started failing, but
that's fixed separately.
Fix all of this by simply initializing the queue numbers to
the invalid value until they're used, if TVQM is enabled, and
also setting them back to that value when the queues are later
freed again.

When installing a (new) key, set the replay counter so that
after FW restart the firmware has the correct value of the
replay counters.
This doesn't have a large effect - for frames that reach
the driver, it will do a replay check, and when installing
a new key, the counter is normally zero to start with (not
for GTK though, if joining the BSS for the first time).
Since this only affects frames handled entirely by the FW,
and that's restricted to a few unicast management frames,
the only affect here is for those after a firmware restart.

We have mgd_prepare_tx(), but sometimes drivers may want/need
to take action when the exchange finishes, whether successfully
or not.
Add a notification to the driver on completion, i.e. call the
new method mgd_complete_tx().
To unify the two scenarios, and to add more information, make
both of them take a struct that has the duration (prepare only),
subtype (both) and success (complete only).

It's been a while that the firmware uses LONG_GROUP by default
and not LEGACY_GROUP.
Until now the firmware wrongly advertise the WOWLAN_GET_STATUS

In order to support both firmwares, first try to get the version
number of the command with the LONG_GROUP and if the firmware
didn't advertise the command version with LONG_GROUP, try to get
the command version with LEGACY_GROUP.

The firmware can now request SMPS (due to thermal conditions), add
some code to honour such requests and bubble them up through the
stack, subject to our other SMPS constraints, e.g. from Bluetooth.
Then, if the firmware requests SMPS, then we know that it supports
a small extension to the PHY configuration API where a chain mask
of 0 means "use 1 but pick which one yourself", so in this case we
use that extension.
During firmware restart, we stay in the previous state, and the FW
will send us a notification at startup (only) if the temperature is
below the lower or above the high threshold, to sync the state.

When we have a P2P Device active, we attempt to only change the
PHY context it uses when we get a new remain-on-channel, if the

This is fine if we're switching within a band, but if we're
switching bands then the switch implies a removal and re-add
of the PHY context, which isn't permitted by the firmware while
it's bound to an interface.

It is not very useful to WARN if we can't send a host command
The firmware is likely in a bad situation and the fact that
we didn't send the host command has an impact on the firmware
only, not on the driver. The driver could clean up all its

Don't WARN in this case, but just leave a smaller note.

When we switch channel, we may miss a few beacons on the
new channel. Don't disconnect if the time event for the
switch ends before we hear the beacons.
Note that this is relevant only for old devices that still
use the TIME_EVENT firmware API for channel switch.
The check that we hear a beacon before the time event
ends was meant to be used for the association time event
and not for the channel switch time event.

When doing scan while 6GHz channels are not enabled, the 6GHz band
is not scanned. Thus, if there are no APs on the 2GHz and 5GHz bands
(that will allow discovery of geographic location etc. that would
allow enabling the 6GHz channels) but there are non collocated APs
on 6GHz PSC channels these would never be discovered.
To overcome this, FW added support for performing passive UHB scan
in case no APs were discovered during scan on the 2GHz and 5GHz
channels.
Add support for enabling such scan when the following conditions are
met:
- 6GHz channels are supported but not enabled by regulatory.
- Station interface is not associated or less than a defined time
interval passed from the last resume or HW reset flows.
- At least 4 channels are included in the scan request
- The scan request includes the widlcard SSID.
- At least 50 minutes passed from the last 6GHz passive scan.

declared in the FW API header files that aren't really firmware,
and the union is also confusing - especially now in the code that

So rework this: change the type of sync and whether to do it in a
synchronous fashion to arguments, and build the data structure in
the function, so we don't need the union.

that the replay detection isn't working correctly. We were

when !ieee80211_has_protected(), which is of course true for

Currently, for all devices and families, failing getting the temp
from the fw is indicated in the log as ERR.
This is too severe for two reasons:
1. The driver has a fall back - and schedules the next temp
read immediately after failing to read temp from the fw.
2. The temp read implementation in the fw is different between
HWs, and on older devices the flow is a-sync and may timeout.
Reducing the print severity from ERR to WARN will allow to
track the issue if it will appear many times, but not frighten users
if it appears once.

We should only allow PPAG to be enabled by OEMs that are in the
approved list. In order to do this, we need to compare the system
vendor string retrieved from SMBIOS to a list maintained in the
driver. If the vendor string is not in the list, we don't allow PPAG
to be used.
For now the list is empty, but entries will be added to it
individually, in subsequent patches.

When version 2 of the PER_PLATFORM_ANT_GAIN_CMD was implemented, we
started copying the values from the command that we have stored into a
local instance. But we accidentally forgot to copy the enabled flag,
so in practice PPAG is never really enabled. Fix this by copying the
flag from our stored data a we should.

We were starting the early time-point too late in non-unified
firmwares. Unlike with unified firmwares, we were starting it only
after reading the NVM, so errors in the NVM read phase were not
logged.
Solve this by moving the time-point to the same place as we do with
unified firmwares, i.e. just before we go into the wait-alive code.

When we check the length, we only check that the advertised
data length fits into the data we have, but currently not
that it actually matches correctly.
This should be harmless, but if the first two bytes are zero,
then the iwl_rx_packet_payload_len() ends up negative, and
that might later cause issues if unsigned variables are used,
as this is not something that's normally expected.
Change the validation here to precisely validate the lengths
match, to avoid such issues.

In roaming flows and during reassociation, its possible that data frames
such as EAPOLs for 4 way handshake/ 802.1x authentication are initially set
to higher MCS rate. Though these are pruned down to a lower legacy rate
before sending to the FW, driver also emits a kernel warning - intended for
non-data frames. Add checks to avoid such warnings for data frames, while
also enhancing the debug data printed.

D3_CONFIG_CMD and D0I3_END_CMD should be the last\first
command upon suspend\resume correspondingly, otherwise,
FW will raise an assert (0x342).
There are firmware notifications that cause the driver to
send a command back to the firmware. If such a notification
is sent to the driver while the the driver prepares the
firmware for D3, operation, what is likely to happen is that
the handling of the notification will try to get the mutex
and will wait unil the driver finished configuring the
firmware for D3. Then the handling notification will get
the mutex and handle the notification which will lead to
the aforementioned ASSERT 342.
To avoid this, we need to prevent any command to be sent to
the firmware between the D3_CONFIG_CMD and the D0I3_END_CMD.
Check this in the utility layer that sends the host commands
and in the transport layer as well.
Flag the D3_CONFIG_CMD and the D0I3_END_CMD commands as
commands that must be sent even if the firmware has already
been configured for D3 operation.

check the mvm's status that has a bit for the suspend

The latter is better because test_bit is atomic. Also
add a call to synchronize_net after we set the bit to
make sure that all the new Tx see the bit before we

We shouldn't trust the firmware with the sizes (or contents)
of notifications, accessing too much data could cause page
faults if the data doesn't fit into the allocated space. This
applies more on older NICs where multiple notifications can
be in a single RX buffer.
Add a general framework for checking a minimum size of any
notification in the RX handlers and use it for most. Some RX
handlers were already checking and I've moved the checks,
some more complex checks I left and made them _NO_SIZE for
the RX handlers.

Currently, _everything_ in cfg80211 holds the RTNL, and if you
have a slow USB device (or a few) you can get some bad lock
contention on that.
Fix that by re-adding a mutex to each wiphy/rdev as we had at
some point, so we have locking for the wireless_dev lists and
all the other things in there, and also so that drivers still
don't have to worry too much about it (they still won't get
parallel calls for a single device).
Then, we can restrict the RTNL to a few cases where we add or
remove interfaces and really need the added protection. Some
of the global list management still also uses the RTNL, since
we need to have it anyway for netdev management, but we only
hold the RTNL for very short periods of time here.

Having sta_id not set for aux_sta and snif_sta can potentially lead to a

this case sta_id 0, an unrelated regular station, will be removed.
In fact, we do have a FW assert that occures rarely and from the debug

There are some races in the hardware that can possibly lead to
a bus lockup later during a restart when we manage to kill the
firmware at a bad time (while it's accessing the bus).
To work around this, add support for a new handshake between
firmware and driver to ensure that the firmware is in a well-
known state before we kill it.

When we get a channel switch with a very long quiet period, we schedule
a work to disconnect after a while. This work runs in background. In the
meanwhile, we keep getting beacons and sending FW modify command for each.
This has a potential race, where we modify the CSA after we aborted it.
Protect the flow by setting csa_failed to true in case we abort, and check
it before sending the modify command.
This required a modification to the way we treat csa_failed in
iwl_mvm_post_channel_switch:
1. The variable isn't being reset anymore, so we can still look at it in
iwl_mvm_channel_switch_rx_beacon. This is fine, since we reset it when
starting a new CSA.
2. There is no more early return in case of csa_failed. This is fine,
since before this patch csa_failed was set only for GO, and for GO the
function is only resetting the power settings, which we want to restore
even in case of failure.

The argument type to iwl_mvm_notify_rx_queue() is currently just
a u8 *, but that's misleading because we actually need the inner
data to be of type struct iwl_mvm_internal_rxq_notif, because we
interpret it when we get it back from the device (to check the
sync bool and possibly the cookie.)
Therefore, clear up any potential confusion and require that the
data passed is of type struct iwl_mvm_internal_rxq_notif *.
Also, while at it, rename the "count" to "notif_size" as "count"
doesn't really clearly say what it's counting.

When adding support for version 3 of the GEO_TX_POWER_LIMIT command,
the table argument of iwl_sar_geo_init was changed from a pointer a 1d
array of now-removed iwl_per_chain_offset_group_v1 to a pointer to a 2d
array of iwl_per_chain_offset (iwl_per_chain_offset_group_v1 was a
struct containing 2 copies of iwl_per_chain_offset).
So even for version 2 where the second dimension is of length 2, which
means that the underlying memory layout of the array didn't change, this
requires a small change in the way we loop over it, and this was missed.
Additionally, for the case of version 3 where the second dimension is now
3, in order to fill the first two elements of each row correctly (lb and
hb), iwl_sar_geo_init must get the true number of bands supported.
But because we don't yet store any values for the 3rd (uhb) band, skip
that band.

As part of changes made to properly support auxiliary activities in CDB
NICs, an aux sta will be added when using hot spot 2.0 and will need
to be removed when roc flow is done.
In order to do so, prepare the roc_done_wk to work synchronously as the
rm_aux_sta is a SYNC command.
Since now all of th iwl_mvm_flush_sta function are using it sync,
removed the flag argument from the function.

If we have only a single RX queue, such as when MSI-X is not
available, we should not send the RFH_QUEUEU_CONFIG_CMD, because our
only queue is the same as the command queue and will be configured as
part of the context info. Our code was actually trying to send the
command with 0 queues, which caused UMAC assert 0x1D04.
Fix that by not sending the command when we have a single queue.

The scan request may specify the request scan dwell time.
However, this value may not always be optimal (e.g. short dwell
time for a passive channel). This may happen in a scan request
as a result of beacon report request, in which the AP may request
an active scan, thus setting a short dwell time, but the station
will perform a passive scan due to regulatory.
Ignore the scan duration parameter and always use the internal
scan dwell time which should be optimal.

The overcome instabilities in the RTT results add smoothing logic
to the reported results. In short, the smoothing logic tracks the
RTT average of each responder for a period of time, and in case
a new RTT results is found to be a spur, the tracked RTT average
is reported instead of the current RTT measurement.
Smooth logic debug configuration using iwl-dbg-cfg.ini:
- MVM_FTM_INITIATOR_ENABLE_SMOOTH: Set to 1 to enable smoothing logic
(default=0).
- MVM_FTM_INITIATOR_SMOOTH_ALPHA: A value between 0 - 100, defining
the weight of the current RTT results vs. the RTT average tracked
based on the previous results. A value of 100 means use only the
current RTT results.
- MVM_FTM_INITIATOR_SMOOTH_AGE_SEC: The maximal time in seconds in which
the RTT average tracked based on previous results is considered valid.
- MVM_FTM_INITIATOR_SMOOTH_UNDERSHOOT: if the current RTT is positive
and below the RTT average by at least this value, report the average
RTT instead of the current one. In units of picoseconds.
- MVM_FTM_INITIATOR_SMOOTH_OVERSHOOT: if the current RTT is positive
and above the RTT average by at least this value, report the average

The the driver prevents new Tx from being sent during the remove-station
flow is by invalidating the fw_id_to_mac_id rcu of that station.
However, if there was any Tx still in-flight (tx-cmd was sent but the
ba-notif wasn't received yet) the ba-response to those frames is simply
ignored without actually reclaiming anything. This later causes the
driver to think that that some of the station's queues aren't empty when
in practice they are which causes errors in the station remove flow.
Fix this by performing the tx-reclaim also if the rcu is invalid. any DB
that can't be updated due to this is not very important at this stage
since the station is about to be removed soon anyways.

A FTM responder may do PASN authentication with unassociated stations
to allow secure ranging. In this case, the driver will add an internal
station and install the TK so the FW will accept protected FTM
request frames from this station and will send a protected FTM

In addition, the driver needs to configure the HLTK to the FW so

The UDP reuseport conflict was a little bit tricky.
The net-next code, via bpf-next, extracted the reuseport handling
into a helper so that the BPF sk lookup code could invoke it.
At the same time, the logic for reuseport handling of unconnected
sockets changed via commit efc6b6f6c3
which changed the logic to carry on the reuseport result into the
rest of the lookup loop if we do not return immediately.
This requires moving the reuseport_has_conns() logic into the callers.
While we are here, get rid of inline directives as they do not belong
in foo.c files.
The other changes were cases of more straightforward overlapping
modifications.

Range request version 10 keeps the same command size as version 9
but uses 2 reserved fields for the responder beacon interval and
station id (if exists).
For now, since the beacon interval of unassoc APs is unknown, use
a value of 100 TUs which is a common value for many APs.
While at it, remove the definition for CCMP_256 cipher, since this

We can currently end up transmitting on an unallocated queue, if

We currently attempt to allocate queues that are 512 entries long,
but that requires 32 KiB memory, which may not be available, at
least not contiguously. If we fail to allocate, attempt to use a
smaller queue all the way down to 16 entries (which fit into a

For ACK_ENABLED and 32BIT_BA_BITMAP flags check the station capabilities
rather than bss_conf.ack_enabled and bss_conf.multi_sta_back_32bit.
These fields are stations capabilities and should not be in bss_conf.
Also note that the bss_conf flags are set in station mode only.

If we set amsdu_len one after another the second one overwrites
the orig_amsdu_len so allow only moving from debug to non debug state.

Somehow we missed this for a long time, but similar to the extended
NSS support in VHT capabilities, we need to have this in Operating
Mode notification.
Implement it by
* parsing the 160/80+80 bit there and setting the bandwidth
appropriately
* having callers of ieee80211_get_vht_max_nss() pass in the current
max NSS value as received in the operating mode notification in
order to modify it appropriately depending on the extended NSS
bits.
This updates all drivers that use it, i.e. only iwlwifi/mvm.

When fixing the initialization race, we neglected to account for
the fact that debugfs is initialized in wiphy_register(), and
some debugfs things went missing (or rather were rerooted to the
global debugfs root).
Fix this by adding debugfs entries only after wiphy_register().
This requires some changes in the rate control code since it
currently adds debugfs at alloc time, which can no longer be
done after the reordering.

The function iwl_mvm_remove_inactive_tids() returns bool, so we
should just check "if (ret)", not "if (ret >= 0)" (which would
do nothing useful here). We obviously therefore cannot use the
return value of the function for the free_queue, we need to use
the queue (i) we're currently dealing with instead.

Due to some hardware issues, queue 31 isn't usable on devices that have
32 queues (7000, 8000, 9000 families), which is correctly reflected in
the configuration and TX queue initialization.
However, the firmware API and queue allocation code assumes that there
are 32 queues, and if something actually attempts to use #31 this leads
to a NULL-pointer dereference since it's not allocated.
Fix this by limiting to 31 in the IWL_MVM_DQA_MAX_DATA_QUEUE, and also
add some code to catch this earlier in the future, if the configuration
changes perhaps.

Third set of patches for v5.7. Nothing really special this time,
business as usual.
When pulling this to net-next there's again a conflict in:
drivers/net/wireless/intel/iwlwifi/pcie/drv.c
To solve this drop these three lines from the conflict (the first hunk
from "HEAD") as the whole AX200 block was moved above in the same
file:
IWL_DEV_INFO(0x2723, 0x1653, iwl_ax200_cfg_cc, iwl_ax200_killer_1650w_name),
IWL_DEV_INFO(0x2723, 0x1654, iwl_ax200_cfg_cc, iwl_ax200_killer_1650x_name),
IWL_DEV_INFO(0x2723, IWL_CFG_ANY, iwl_ax200_cfg_cc, iwl_ax200_name),
And keep all the __IWL_DEV_INFO() entries (the second hunk). In other
words, take everything from wireless-drivers-next. When running 'git
diff' after the resolution the output should be empty.
Major changes:

To solve this drop these three lines from the conflict (the first hunk
from "HEAD") as the whole AX200 block was moved above in the same
file:
IWL_DEV_INFO(0x2723, 0x1653, iwl_ax200_cfg_cc, iwl_ax200_killer_1650w_name),

IWL_DEV_INFO(0x2723, IWL_CFG_ANY, iwl_ax200_cfg_cc, iwl_ax200_name),
And keep all the __IWL_DEV_INFO() entries (the second hunk). In other
words, take everything from wireless-drivers-next. When running 'git
diff' after the resolution the output should be empty.
Major changes:

* handle RX fragments
* enable PN offload
* add support for HE BSS color
iwlwifi
* support new FW API version
* support for EDCA measurements

Some of the places using this want the newline, but not all,
so remove the newline from it and generate it in the debugfs
files where it's desired.
The effect of this is not printing double newlines in debug

This new command is mostly backwards compatible, with the exception
that the device_type element was changed into a bitmask. The device
type bit remains the same (because we only had 0 and 1 anyway), but
when using v1 we can't set any other bits, because that would change
the integer.
Other than that, the struct remains the same and the driver can set
the device_type bit in both cases, but it can only set the low_latency
bit if VER_2 is used.

These values are selected based on the PCI device ID, so the decision
to use them can be made early. By moving them to the trans_cfg, we
avoid duplicating the large cfg structs for small pieces of
data (sometimes a single boolean). This will also allow us to make
more decisions based on, for instance, the SoC type in used.
The trans_cfg concept changes a bit, because previously it was used
only to boot the device before reading further characteristics and now
it also contains more data that is associated with the device ID.

The logic for checking required NVM sections was recently fixed in
commit b3f20e0982 ("iwlwifi: mvm: fix NVM check for 3168
devices"). However, with that fixed the else is now taken for 3168
devices and within the else clause there is a mandatory check for the
PHY_SKU section. This causes the parsing to fail for 3168 devices.
The PHY_SKU section is really only mandatory for the IWL_NVM_EXT
layout (the phy_sku parameter of iwl_parse_nvm_data is only used when
the NVM type is IWL_NVM_EXT). So this changes the PHY_SKU section
check so that it's only mandatory for IWL_NVM_EXT.

When a FTM request is aborted, the driver sends the abort command to
the fw and waits for a response. When the response arrives, the driver
calls cfg80211_pmsr_complete() for that request.
However, cfg80211 frees the requested data immediately after sending
the abort command, so this may lead to use after free.
Fix it by clearing the request data in the driver when the abort
command arrives and ignoring the fw notification that will come
afterwards.

Till now, the driver asked the fw for a DTS measurement in automatic
mode. This triggered a flow in which the fw actively measured the
temperature. This is not needed anymore, as the fw performs
measurements by itself, without the driver triggering them, and the
current cadence in which the fw performs such measurements is
sufficient.
In addition, in some time-sensitive scenarios, in which the driver asks
the fw for an active measurement twice in a short time (<100ms), the fw
asserts with code 0x20100801.
Change the DTS measurement to _WITHOUT_MEASURE instead, so the fw will
respond with the last measurement it has performed.

The IGTK keys are only removed by mac80211 after it has already
removed the AP station. This causes the driver to throw an error
because mac80211 is trying to remove the IGTK when the station doesn't
exist anymore.
The firmware is aware that the station has been removed and can deal
with it the next time we try to add an IGTK for a station, so we
shouldn't try to remove the key if the station ID is
IWL_MVM_INVALID_STA. Do this by removing the check for mvm_sta before
calling iwl_mvm_send_sta_igtk() and check return from that function
gracefully if the station ID is invalid.

Since v5.4-rc1 was released, iwlwifi started throwing errors when scan

the OTP burned in the device, which contains the list of available
channels). For instance:
iwlwifi 0000:00:14.3: FW error in SYNC CMD SCAN_CFG_CMD
This bug was reported in the ArchLinux bug tracker:

This is an old parameter that was used supposed to be used only when
LAR was still under development. It should not be used anymore, but,
since it's available, end-users have been mangling with it
unnecessarily. In some cases it can cause problems because when LAR

When we transmit after TXQ dequeue, we aren't paying attention to
the return value of the transmit functions, leading to a potential
SKB leak.
Refactor the code a bit (and rename ..._tx to ..._tx_sta) to check
for this happening.

It used to be the case that if we got here, we wouldn't warn
but instead allocate the queue (DQA). With using the mac80211
TXQs model this changed, and we really have nothing to do with
the frame here anymore, hence the warning now.
However, clearly we missed in coding & review that this is now
a pure error path and leaks the SKB if we return 0 instead of
an indication that the SKB needs to be freed. Fix this.

If we have offloaded rate scaling, which is always true for those
devices supporting HE, then report the TX rate directly from the
data the firmware gives us, instead of only passing it to mac80211
on frame status only and for it to track it.
First of all, this makes us always report the last good rate that
the rate scaling algorithm picked, which is better than reporting
the last rate for any frame since management frames etc. are sent
with very low rates and could interfere.
Additionally, this allows us to properly report HE rates, though
in case there's a lot of trigger-based traffic, we don't get any
choice in the rates and don't report that properly right now.

We had a check on !NVM_EXT and then a check for NVM_SDP in the else
block of this if. The else block, obviously, could only be reached if
using NVM_EXT, so it would never be NVM_SDP.
Fix that by checking whether the nvm_type is IWL_NVM instead of
checking for !IWL_NVM_EXT to solve this issue.

As noted in the previous commit, due to the way we allocate the
dev_cmd headers with 324 byte size, and 4/8 byte alignment, the
part we use of them (bytes 20..40-68) could still cross a page
and thus 2^32 boundary.
Address this by using alignment to ensure that the allocation
cannot cross a page boundary, on hardware that's affected. To
make that not cause more memory consumption, reduce the size of
the allocations to the necessary size - we go from 324 bytes in
each allocation to 60/68 on gen2 depending on family, and ~120
or so on gen1 (so on gen1 it's a pure reduction in size, since
we don't need alignment there).
To avoid size and clearing issues, add a new structure that's
just the header, and use kmem_cache_zalloc().

This fixes a long-standing bug - we haven't been able to check the
firmware image that was loaded for D3/not-D3 since the introduction
of the unified image...
Fix this by keeping a status flag for D3 instead of checking for
the firmware image that's loaded.
This reduces occurrences of checks for IWL_UCODE_WOWLAN to just the
code that actually loads the image or deals with it in other ways.

There are various of flows which require tids flushing
(disconnection, suspend, etc...).
Currently, when the driver instructs the FW to flush
he masks all the data tids(0-7).
However, the driver doesn't set the management tid (#15)
which cause the FW not to flush it.
When the FW tries to remove the mgmt queue he throws an assert
since it is not an empty queue.
instead of just set only the data tids set everything and let
the FW ignore the invalid tids.
