struct net_device shouldn't be embedded into any structure, instead,
the owner should use the priv space to embed their state into net_device.
Embedding net_device into structures prohibits the usage of flexible
arrays in the net_device structure. For more details, see the discussion
at [1].
Un-embed the net_device from struct iwl_trans_pcie by converting it
into a pointer. Then use the leverage alloc_netdev() to allocate the
net_device object at iwl_trans_pcie_alloc.
The private data of net_device becomes a pointer for the struct
iwl_trans_pcie, so, it is easy to get back to the iwl_trans_pcie parent
given the net_device object.

On older devices (before unified image!) we can end up calling
stop_device from an rfkill interrupt. However, in stop_device
we attempt to synchronize IRQs, which then of course deadlocks.
Avoid this by checking the context, if running from the IRQ
thread then don't synchronize. This wouldn't be correct on a
new device since RSS is supported, but older devices only have
a single interrupt/queue.

having this all through the API with calls up and down,
just implemented a special-case CMD_BLOCK_TXQS flag for

we lock the cmd queue and then the TXQs in the reclaim

There's a race with runtime PM getting enabled by userspace:
- we rescan the PCI bus
- this creates the new PCI device including its sysfs
representation
- udev sees the new device, and the (OS-specific?) scripting
enables runtime PM by writing to power/control; this can
happen _before_ the next step - this will runtime-suspend
the device which saves the config space, including the BAR0
that wasn't assigned yet
- the bus rescan assigns resources to the devices and writes
them to the config space of the device
(but not the runtime-pm saved copy)
- the driver binds and this disallows runtime PM, so the device
is resumed, restoring the (incomplete!) config space
- the driver cannot work due to BAR0 not being configured
Fixing the actual race is hard and deep in the PCI layer,
though probably should be done for upstream as well; perhaps
runtime PM should only be allowed after resource assignment,
or some other TBD way.
Work around this in the driver for now by simply (re-)assigning
BAR0 when the driver initializes, if it's unset.

If the bus has no parent due to the topology, the device rescan
(after some kind of reset was detected) wouldn't work. On the
other hand, some platforms appear to require scanning the parent,
though it's not clear why.
However if there's no parent, then we skip the rescan, which isn't a
good idea. Change the code to go to the parent only if that exists,
and rescan the bus itself where it doesn't.

This is equivalent to 'gen2', and it was always confusing to have
two identical config entries. The split config patch actually had
been originally developed after removing 'use_tfh" and didn't add
the use_tfh in the new configs as they'd later been copied to the
new files. Thus the easiest way to fix the init crash here now is
to just remove use_tfh (which is erroneously unset in most of the
configs now) and use 'gen2' in the code instead.
There's possibly still an unwind error in iwl_txq_gen2_init() as
it crashes if TXQ 0 fails to initialize, but we can deal with it
later since the original failure is due to the use_tfh confusion.

Core
----
- Rework the sendpage & splice implementations. Instead of feeding
data into sockets page by page extend sendmsg handlers to support
taking a reference on the data, controlled by a new flag called
MSG_SPLICE_PAGES. Rework the handling of unexpected-end-of-file
to invoke an additional callback instead of trying to predict what
the right combination of MORE/NOTLAST flags is.
Remove the MSG_SENDPAGE_NOTLAST flag completely.
- Implement SCM_PIDFD, a new type of CMSG type analogous to
SCM_CREDENTIALS, but it contains pidfd instead of plain pid.
- Enable socket busy polling with CONFIG_RT.
- Improve reliability and efficiency of reporting for ref_tracker.
- Auto-generate a user space C library for various Netlink families.
Protocols
---------
- Allow TCP to shrink the advertised window when necessary, prevent
sk_rcvbuf auto-tuning from growing the window all the way up to
tcp_rmem[2].
- Use per-VMA locking for "page-flipping" TCP receive zerocopy.
- Prepare TCP for device-to-device data transfers, by making sure
that payloads are always attached to skbs as page frags.
- Make the backoff time for the first N TCP SYN retransmissions
linear. Exponential backoff is unnecessarily conservative.
- Create a new MPTCP getsockopt to retrieve all info (MPTCP_FULL_INFO).
- Avoid waking up applications using TLS sockets until we have
a full record.
- Allow using kernel memory for protocol ioctl callbacks, paving
the way to issuing ioctls over io_uring.
- Add nolocalbypass option to VxLAN, forcing packets to be fully
encapsulated even if they are destined for a local IP address.
- Make TCPv4 use consistent hash in TIME_WAIT and SYN_RECV. Ensure
in-kernel ECMP implementation (e.g. Open vSwitch) select the same
link for all packets. Support L4 symmetric hashing in Open vSwitch.
- PPPoE: make number of hash bits configurable.
- Allow DNS to be overwritten by DHCPACK in the in-kernel DHCP client
(ipconfig).
- Add layer 2 miss indication and filtering, allowing higher layers
(e.g. ACL filters) to make forwarding decisions based on whether
packet matched forwarding state in lower devices (bridge).
- Support matching on Connectivity Fault Management (CFM) packets.
- Hide the "link becomes ready" IPv6 messages by demoting their
printk level to debug.
- HSR: don't enable promiscuous mode if device offloads the proto.
- Support active scanning in IEEE 802.15.4.
- Continue work on Multi-Link Operation for WiFi 7.
BPF
---
- Add precision propagation for subprogs and callbacks. This allows
maintaining verification efficiency when subprograms are used,
or in fact passing the verifier at all for complex programs,
especially those using open-coded iterators.
- Improve BPF's {g,s}setsockopt() length handling. Previously BPF
assumed the length is always equal to the amount of written data.
But some protos allow passing a NULL buffer to discover what
the output buffer *should* be, without writing anything.
- Accept dynptr memory as memory arguments passed to helpers.
- Add routing table ID to bpf_fib_lookup BPF helper.
- Support O_PATH FDs in BPF_OBJ_PIN and BPF_OBJ_GET commands.
- Drop bpf_capable() check in BPF_MAP_FREEZE command (used to mark
maps as read-only).
- Show target_{obj,btf}_id in tracing link fdinfo.
- Addition of several new kfuncs (most of the names are self-explanatory):
- Add a set of new dynptr kfuncs: bpf_dynptr_adjust(),
bpf_dynptr_is_null(), bpf_dynptr_is_rdonly(), bpf_dynptr_size()
and bpf_dynptr_clone().
- bpf_task_under_cgroup()
- bpf_sock_destroy() - force closing sockets
- bpf_cpumask_first_and(), rework bpf_cpumask_any*() kfuncs
Netfilter
---------
- Relax set/map validation checks in nf_tables. Allow checking
presence of an entry in a map without using the value.
- Increase ip_vs_conn_tab_bits range for 64BIT builds.
- Allow updating size of a set.
- Improve NAT tuple selection when connection is closing.
Driver API
----------
- Integrate netdev with LED subsystem, to allow configuring HW
"offloaded" blinking of LEDs based on link state and activity
(i.e. packets coming in and out).
- Support configuring rate selection pins of SFP modules.
- Factor Clause 73 auto-negotiation code out of the drivers, provide
common helper routines.
- Add more fool-proof helpers for managing lifetime of MDIO devices
associated with the PCS layer.
- Allow drivers to report advanced statistics related to Time Aware
scheduler offload (taprio).
- Allow opting out of VF statistics in link dump, to allow more VFs
to fit into the message.
- Split devlink instance and devlink port operations.

Save the pnvm payloads in several DRAM segments (not only in one as
used to). In addition, allocate a FW structure in DRAM that holds the
segments' addresses and forward its address to the FW. It's done when
FW has the capability to handle pnvm images this way (helps to process
large pnvm images).

An integer overflow occurs in the iwl_write_to_user_buf() function,
which is called by the iwl_dbgfs_monitor_data_read() function.
static bool iwl_write_to_user_buf(char __user *user_buf, ssize_t count,
void *buf, ssize_t *size,
ssize_t *bytes_copied)
{
int buf_size_left = count - *bytes_copied;
buf_size_left = buf_size_left - (buf_size_left % sizeof(u32));
if (*size > buf_size_left)
*size = buf_size_left;
If the user passes a SIZE_MAX value to the "ssize_t count" parameter,
the ssize_t count parameter is assigned to "int buf_size_left".
Then compare "*size" with "buf_size_left" . Here, "buf_size_left" is a
negative number, so "*size" is assigned "buf_size_left" and goes into
the third argument of the copy_to_user function, causing a heap overflow.
This is not a security vulnerability because iwl_dbgfs_monitor_data_read()
is a debugfs operation with 0400 privileges.

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.

Most of this change is a continuation of commit 403ea939ea
("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.

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.)

iwlmei needs to know about the follwing events:
* Association
* De-association
* Country Code change
* SW Rfkill change
* SAR table changes
iwlmei can take the device away from us, so report the new
rfkill type when this happens.
Advertise the required data from the CSME firmware to the
usersapce: mostly, the AP that the CSME firmware is currently
associated to in case there is an active link protection
session.
Generate the HOST_ASSOC / HOST_DISSASSOC messages.
Don't support WPA1 (non-RSNA) for now.
Don't support shared wep either.
We can then determine the AUTH parameter by checking the AKM.
Feed the cipher from the key installation.
SW Rfkill will be implemented later when cfg80211 will
allow us to read the SW Rfkill state.

v7: Ayala added her signed-off
remove pointless function declaration
fix a bug due to merge conflict in the HOST_ASSOC message
v8: leave a print if we have a SAP connection on a device we do
not support (yet)
