Add redirect_neigh() BPF packet redirect helper, allowing to limit stack
traversal in common container configs and improving TCP back-pressure.
Daniel reports ~10Gbps => ~15Gbps single stream TCP performance gain.
Expand netlink policy support and improve policy export to user space.
(Ge)netlink core performs request validation according to declared
policies. Expand the expressiveness of those policies (min/max length
and bitmasks). Allow dumping policies for particular commands.
This is used for feature discovery by user space (instead of kernel
version parsing or trial and error).
Support IGMPv3/MLDv2 multicast listener discovery protocols in bridge.
Allow more than 255 IPv4 multicast interfaces.
Add support for Type of Service (ToS) reflection in SYN/SYN-ACK
packets of TCPv6.
In Multi-patch TCP (MPTCP) support concurrent transmission of data
on multiple subflows in a load balancing scenario. Enhance advertising
addresses via the RM_ADDR/ADD_ADDR options.
Support SMC-Dv2 version of SMC, which enables multi-subnet deployments.
Allow more calls to same peer in RxRPC.
Support two new Controller Area Network (CAN) protocols -
CAN-FD and ISO 15765-2:2016.
Add xfrm/IPsec compat layer, solving the 32bit user space on 64bit
kernel problem.
Add TC actions for implementing MPLS L2 VPNs.
Improve nexthop code - e.g. handle various corner cases when nexthop
objects are removed from groups better, skip unnecessary notifications
and make it easier to offload nexthops into HW by converting
to a blocking notifier.
Support adding and consuming TCP header options by BPF programs,
opening the doors for easy experimental and deployment-specific
TCP option use.
Reorganize TCP congestion control (CC) initialization to simplify life
of TCP CC implemented in BPF.
Add support for shipping BPF programs with the kernel and loading them
early on boot via the User Mode Driver mechanism, hence reusing all the
user space infra we have.
Support sleepable BPF programs, initially targeting LSM and tracing.
Add bpf_d_path() helper for returning full path for given 'struct path'.
Make bpf_tail_call compatible with bpf-to-bpf calls.
Allow BPF programs to call map_update_elem on sockmaps.
Add BPF Type Format (BTF) support for type and enum discovery, as
well as support for using BTF within the kernel itself (current use
is for pretty printing structures).
Support listing and getting information about bpf_links via the bpf
syscall.
Enhance kernel interfaces around NIC firmware update. Allow specifying
overwrite mask to control if settings etc. are reset during update;
report expected max time operation may take to users; support firmware
activation without machine reboot incl. limits of how much impact
reset may have (e.g. dropping link or not).
Extend ethtool configuration interface to report IEEE-standard
counters, to limit the need for per-vendor logic in user space.
Adopt or extend devlink use for debug, monitoring, fw update
in many drivers (dsa loop, ice, ionic, sja1105, qed, mlxsw,
mv88e6xxx, dpaa2-eth).
In mlxsw expose critical and emergency SFP module temperature alarms.
Refactor port buffer handling to make the defaults more suitable and
support setting these values explicitly via the DCBNL interface.
Add XDP support for Intel's igb driver.
Support offloading TC flower classification and filtering rules to
mscc_ocelot switches.
Add PTP support for Marvell Octeontx2 and PP2.2 hardware, as well as
fixed interval period pulse generator and one-step timestamping in
dpaa-eth.
Add support for various auth offloads in WiFi APs, e.g. SAE (WPA3)
offload.
Add Lynx PHY/PCS MDIO module, and convert various drivers which have
this HW to use it. Convert mvpp2 to split PCS.
Support Marvell Prestera 98DX3255 24-port switch ASICs, as well as
7-port Mediatek MT7531 IP.
Add initial support for QCA6390 and IPQ6018 in ath11k WiFi driver,
and wcn3680 support in wcn36xx.
Improve performance for packets which don't require much offloads
on recent Mellanox NICs by 20% by making multiple packets share
a descriptor entry.
Move chelsio inline crypto drivers (for TLS and IPsec) from the crypto
subtree to drivers/net. Move MDIO drivers out of the phy directory.
Clean up a lot of W=1 warnings, reportedly the actively developed
subsections of networking drivers should now build W=1 warning free.
Make sure drivers don't use in_interrupt() to dynamically adapt their
code. Convert tasklets to use new tasklet_setup API (sadly this
conversion is not yet complete).

The usage of in_interrupt() in non-core code is phased out.
The debugging macros in these drivers use in_interrupt() to print 'I' or
'U' depending on the return value of in_interrupt(). While 'U' is confusing
at best and 'I' is not really describing the actual context (hard interupt,
soft interrupt, bottom half disabled section) these debug macros originate
from the pre ftrace kernel era and their value today is questionable. They
probably should be removed completely.
The macros weere added initially for ipw2100 and then spreaded when the
driver was forked.
Remove the in_interrupt() usage at least..

The wrappers in include/linux/pci-dma-compat.h should go away.
The patch has been generated with the coccinelle script below and has been
hand modified to replace GFP_ with a correct flag.
It has been compile tested.
When memory is allocated in 'ipw2100_msg_allocate()' (ipw2100.c),
GFP_KERNEL can be used because it is called from the probe function.
The call chain is:
ipw2100_pci_init_one (the probe function)
--> ipw2100_queues_allocate
--> ipw2100_msg_allocate
Moreover, 'ipw2100_msg_allocate()' already uses GFP_KERNEL for some other
memory allocations.
When memory is allocated in 'status_queue_allocate()' (ipw2100.c),
GFP_KERNEL can be used because it is called from the probe function.
The call chain is:
ipw2100_pci_init_one (the probe function)
--> ipw2100_queues_allocate
--> ipw2100_rx_allocate
--> status_queue_allocate
Moreover, 'ipw2100_rx_allocate()' already uses GFP_KERNEL for some other
memory allocations.
When memory is allocated in 'bd_queue_allocate()' (ipw2100.c),
GFP_KERNEL can be used because it is called from the probe function.
The call chain is:
ipw2100_pci_init_one (the probe function)
--> ipw2100_queues_allocate
--> ipw2100_rx_allocate
--> bd_queue_allocate
Moreover, 'ipw2100_rx_allocate()' already uses GFP_KERNEL for some other

When memory is allocated in 'ipw_queue_tx_init()' (ipw2200.c),
GFP_KERNEL can be used because it is called from a call chain that already
uses GFP_KERNEL and no spin_lock is taken in the between.
The call chain is:
ipw_up
--> ipw_load
--> ipw_queue_reset
--> ipw_queue_tx_init
'ipw_up()' already uses GFP_KERNEL for some other memory allocations.

The call chain is:
ipw2100_pci_init_one (the probe function)
--> ipw2100_queues_allocate
--> ipw2100_tx_allocate
No lock is taken in the between.
So it is safe to use GFP_KERNEL in 'ipw2100_tx_allocate()'.
BTW, 'ipw2100_queues_allocate()' also calls 'ipw2100_msg_allocate()' which
already allocates some memory using GFP_KERNEL.

Reduces attack surface on kernel devs opening the links for MITM
as HTTPS traffic is much harder to manipulate.
Deterministic algorithm:
For each file:
If not .svg:
For each line:
If doesn't contain `\bxmlns\b`:
For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`:
If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`:
If both the HTTP and HTTPS versions

First set of patches for v5.9. This comes later than usual as I was
offline for two weeks. The biggest change here is moving Microchip
wilc1000 driver from staging. There was an immutable topic branch with
one commit moving the whole driver and the topic branch was pulled
both to staging-next and wireless-drivers-next. At the moment the only
reported conflict is in MAINTAINERS file, so I'm hoping the move
should go smoothly.
Other notable changes are ath11k getting 6 GHz band support and rtw88
supporting RTL8821CE. And there's also the usual fixes, API changes
and cleanups all over.
Major changes:
wilc1000
* move from drivers/staging to drivers/net/wireless/microchip
ath11k
* add 6G band support
* add spectral scan support
iwlwifi
* make FW reconfiguration quieter by not using warn level
rtw88
* add support for RTL8821CE

With legacy PM, drivers themselves were responsible for managing the
device's power states and takes care of register states.
After upgrading to the generic structure, PCI core will take care of
required tasks and drivers should do only device-specific operations.
The driver was invoking PCI helper functions like pci_save/restore_state(),
pci_enable/disable_device() and pci_set_power_state(), which is not
recommended.
Compile-tested only.

Organize driver documentation by device type. Most documents
have fairly verbose yet uninformative names, so let users
first select a well defined device type, and then search for
a particular driver.
While at it rename the section from Vendor drivers to
Hardware drivers. This seems more accurate, besides people
sometimes refer to out-of-tree drivers as vendor drivers.

Since commit 84af7a6194 ("checkpatch: kconfig: prefer 'help' over
'---help---'"), the number of '---help---' has been gradually
decreasing, but there are still more than 2400 instances.
This commit finishes the conversion. While I touched the lines,
I also fixed the indentation.
There are a variety of indentation styles found.
a) 4 spaces + '---help---'
b) 7 spaces + '---help---'
c) 8 spaces + '---help---'
d) 1 space + 1 tab + '---help---'
e) 1 tab + '---help---' (correct indentation)
f) 1 tab + 1 space + '---help---'
g) 1 tab + 2 spaces + '---help---'
In order to convert all of them to 1 tab + 'help', I ran the
following commend:
$ find . -name 'Kconfig*' | xargs sed -i 's/^[[:space:]]*---help---/\thelp/'

The current codebase makes use of the zero-length array language
extension to the C90 standard, but the preferred mechanism to declare
variable-length types such as these ones is a flexible array member[1][2],
introduced in C99:
struct foo {
int stuff;
struct boo array[];
};
By making use of the mechanism above, we will get a compiler warning
in case the flexible array does not occur last in the structure, which
will help us prevent some kind of undefined behavior bugs from being
inadvertently introduced[3] to the codebase from now on.
Also, notice that, dynamic memory allocations won't be affected by
this change:
"Flexible array members have incomplete type, and so the sizeof operator
may not be applied. As a quirk of the original implementation of
zero-length arrays, sizeof evaluates to zero."[1]
sizeof(flexible-array-member) triggers a warning because flexible array
members have incomplete type[1]. There are some instances of code in
which the sizeof operator is being incorrectly/erroneously applied to
zero-length arrays and the result is zero. Such instances may be hiding
some bugs. So, this work (flexible-array member conversions) will also
help to get completely rid of those sorts of issues.
This issue was found with the help of Coccinelle.

Documentation/networking/ is full of cryptically named files with
driver documentation. This makes finding interesting information
at a glance really hard. Move all those files into a directory
called device_drivers (since not all drivers are for device) and
fix up references.
RFC v0.1 -> RFC v1:
- also add .txt suffix to the files which are missing it (Quentin)

Variables len, ret, reason and crypt are assigned values that
are never read, hence they are redundant and can be removed.
Note: For the variable ret, a return code is being assigned, but
this is not returned and 0 is currently being returned, I believe
this is OK.
Cleans up clang warnings:
warning: variable 'len' set but not used [-Wunused-but-set-variable]
variable 'ret' set but not used [-Wunused-but-set-variable]
warning: variable 'reason' set but not used [-Wunused-but-set-variable]

The ipw2x00 driver family uses get_seconds() to read the current time
for various purposes. This function is deprecated because of the 32-bit
time_t overflow, and it can cause unexpected behavior when the time
changes due to settimeofday() calls or leap second updates.
In many cases, we want to use monotonic time instead, however ipw2x00
explicitly tracks the time spent in suspend, so this changes the
driver over to use ktime_get_boottime_seconds(), which is slightly
slower, but not used in a fastpath here.
