Currently, upon the reception of an ADD_ADDR (and when the fullmesh flag
is not used), the in-kernel PM will create new subflows using the local
address the routing configuration will pick.
It would be easier to pick local addresses from a selected list of
endpoints, and use it only once, than relying on routing rules.
Use case: both the client (C) and the server (S) have two addresses (a
and b). The client establishes the connection between C(a) and S(a).
Once established, the server announces its additional address S(b). Once
received, the client connects to it using its second address C(b).
Compared to a situation without the 'laminar' endpoint for C(b), the
client didn't use this address C(b) to establish a subflow to the
server's primary address S(a). So at the end, we have:
C S
C(a) --- S(a)
C(b) --- S(b)
In case of a 3rd address on each side (C(c) and S(c)), upon the
reception of an ADD_ADDR with S(c), the client should not pick C(b)
because it has already been used. C(c) should then be used.
Note that this situation is currently possible if C doesn't add any
endpoint, but configure the routing in order to pick C(b) for the route
to S(b), and pick C(c) for the route to S(c). That doesn't sound very
practical because it means knowing in advance the IP addresses that
will be used and announced by the server.
'laminar', like the idea of laminar flows: the different subflows don't
mix with each other on an endpoint, unlike the "turbulent" way traffic
is mixed by 'fullmesh'.
In the code, the new endpoint type is added. Similar to the other
subflow types, an MPTCP_INFO counter is added. While at it, hole are now
commented in struct mptcp_info, to remember next time that these holes
can no longer be used.

A few variables linked to the in-kernel Path-Manager are confusing, and
it would help current and future developers, to clarify them.
One of them is 'local_addr_max', which in fact represents the maximum
number of 'subflow' endpoints that can be used to create new subflows,
and not the number of local addresses that have been used to create
subflows.
While at it, add an additional name for the corresponding variable in
MPTCP INFO: mptcpi_endp_subflow_max. Not to break the current uAPI, the
new name is added as a 'define' pointing to the former name. This will
then also help userspace devs.
Also move the variable and function next to the other 'endp_X_max' ones.
No functional changes intended.

The CAN XL netlink interface will also have data bitrate and TDC
parameters. The current FD parameters do not have a prefix in their
names to differentiate them.
Because the netlink interface is part of the UAPI, it is unfortunately
not feasible to rename the existing symbols to add an FD_ prefix. The
best alternative is to add a comment for each of the symbols to notify
the reader of which parts are CAN FD specific.
While at it, fix a typo: transiver -> transceiver.

This attribute is a boolean. No need to add it to set it to 'false'.
Indeed, the default value when this attribute is not set is naturally
'false'. A few bytes can then be saved by not adding this attribute if
the connection is not on the server side.
This prepares the future deprecation of its attribute, in favour of a
new flag.

Commit 6138e687c7b6 ("ptp: Introduce strict checking of external time stamp
options.") added the PTP_STRICT_FLAGS to the set of flags supported for the
external timestamp request ioctl.
It is only supported by PTP_EXTTS_REQUEST2, as it was introduced the
introduction of the new ioctls. Further, the kernel has always set this
flag for PTP_EXTTS_REQUEST2 regardless of whether or not the user requested
the behavior.
This effectively means that the flag is not useful for userspace. If the
user issues a PTP_EXTTS_REQUEST ioctl, the flag is ignored due to not being
supported on the old ioctl. If the user issues a PTP_EXTTS_REQUEST2 ioctl,
the flag will be set by the kernel regardless of whether the user set the
flag in their structure.
Add a comment documenting this behavior in the uAPI header file.

Various network interface types make use of needed_{head,tail}room values
to efficiently reserve buffer space for additional encapsulation headers,
such as VXLAN, Geneve, IPSec, etc. However, it is not currently possible
to query these values in a generic way.
Introduce ability to query the needed_{head,tail}room values of a network
device via rtnetlink, such that applications that may wish to use these
values can do so.
For example, Cilium agent iterates over present devices based on user config
(direct routing, vxlan, geneve, wireguard etc.) and in future will configure
netkit in order to expose the needed_{head,tail}room into K8s pods. See
b9ed315d3c4c ("netkit: Allow for configuring needed_{head,tail}room").

Currently, the S1G channelisation implementation differs from that of
VHT, which is the PHY that S1G is based on. The major difference between
the clock rate is 1/10th of VHT. However how their channelisation is
represented within cfg80211 and mac80211 vastly differ.
To rectify this, remove the use of IEEE80211_CHAN_1/2/4.. flags that were
previously used to indicate the control channel width, however it should be
implied that the control channels are 1MHz in the case of S1G. Additionally,
introduce the invert - being IEEE80211_CHAN_NO_4/8/16MHz - that imply
the control channel may not be used for a certain bandwidth. With these
new flags, we can perform regulatory and chandef validation just as we would
for VHT.
To deal with the notion that S1G PHYs may contain a 2MHz primary channel,
introduce a new variable, s1g_primary_2mhz, which indicates whether we are
operating on a 2MHz primary channel. In this case, the chandef::chan points to
the 1MHz primary channel pointed to by the primary channel location. Alongside
this, introduce some new helper routines that can extract the sibling 1MHz
channel. The sibling being the alternate 1MHz primary subchannel within the
2MHz primary channel that is not pointed to by chandef::chan.
Furthermore, due to unique restrictions imposed on S1G PHYs, introduce
a new flag, IEEE80211_CHAN_S1G_NO_PRIMARY, which states that the 1MHz channel
cannot be used as a primary channel. This is assumed to be set by vendors
as it is hardware and regdom specific, When we validate a 2MHz primary channel,
we need to ensure both 1MHz subchannels do not contain this flag. If one or
both of the 1MHz subchannels contain this flag then the 2MHz primary is not
permitted for use as a primary channel.
Properly integrate S1G channel validation such that it is implemented
according with other PHY types such as VHT. Additionally, implement a new
S1G-specific regulatory flag to allow cfg80211 to understand specific
vendor requirements for S1G PHYs.

This notification will be used by the device to inform user space
about upcoming DW. When received, user space will be able to prepare
multicast Service Discovery Frames (SDFs) to be transmitted during the
next DW using %NL80211_CMD_FRAME command on the NAN management interface.
The device/driver will take care to transmit the frames in the correct
timing. This allows to implement a synchronized Discovery Engine (DE)
in user space, if the device doesn't support DE offload.
Note that this notification can be sent before the actual DW starts as

Add the ability to install PSP Rx and Tx crypto keys on TCP
connections. Netlink ops are provided for both operations.
Rx side combines allocating a new Rx key and installing it
on the socket. Theoretically these are separate actions,
but in practice they will always be used one after the
other. We can add distinct "alloc" and "install" ops later.

The "PSP device" is its own object. This allows us to perform more
flexible reference counting / lifetime control than if PSP information
was part of net_device. In the future we should also be able
to "delegate" PSP access to software devices, such as *vlan, veth

- From the 2nd retransmitted SYN, stop AccECN negotiation
- Remove option from SYN/ACK rexmits to handle blackholes
- If no option arrives in SYN/ACK, assume Option is not usable
- If an option arrives later, re-enabled
- If option is zeroed, disable AccECN option processing

The Accurate ECN allows echoing back the sum of bytes for
each IP ECN field value in the received packets using
AccECN option. This change implements AccECN option tx & rx
side processing without option send control related features
that are added by a later change.
Based on specification:
https://tools.ietf.org/id/draft-ietf-tcpm-accurate-ecn-28.txt
(Some features of the spec will be added in the later changes
rather than in this one).
A full-length AccECN option is always attempted but if it does
not fit, the minimum length is selected based on the counters
that have changed since the last update. The AccECN option
(with 24-bit fields) often ends in odd sizes so the option
write code tries to take advantage of some nop used to pad
the other TCP options.
The delivered_ecn_bytes pairs with received_ecn_bytes similar
to how delivered_ce pairs with received_ce. In contrast to
ACE field, however, the option is not always available to update
delivered_ecn_bytes. For ACK w/o AccECN option, the delivered
bytes calculated based on the cumulative ACK+SACK information
are assigned to one of the counters using an estimation
heuristic to select the most likely ECN byte counter. Any
estimation error is corrected when the next AccECN option
arrives. It may occur that the heuristic gets too confused
when there are enough different byte counter deltas between
ACKs with the AccECN option in which case the heuristic just
gives up on updating the counters for a while.
tcp_ecn_option sysctl can be used to select option sending
mode for AccECN: TCP_ECN_OPTION_DISABLED, TCP_ECN_OPTION_MINIMUM,
and TCP_ECN_OPTION_FULL.
This patch increases the size of tcp_info struct, as there is
no existing holes for new u32 variables. Below are the pahole
outcomes before and after this patch:
[BEFORE THIS PATCH]

group for new u8 members, but adds a 4-byte hole in tcp_sock_write_rx

During the connection establishment, a peer can tell the other one that
it cannot establish new subflows to the initial IP address and port by
setting the 'C' flag [1]. Doing so makes sense when the sender is behind
a strict NAT, operating behind a legacy Layer 4 load balancer, or using
anycast IP address for example.
When this 'C' flag is set, the path-managers must then not try to
establish new subflows to the other peer's initial IP address and port.
The in-kernel PM has access to this info, but the userspace PM didn't.
The RFC8684 [1] is strict about that:
(...) therefore the receiver MUST NOT try to open any additional
subflows toward this address and port.
So it is important to tell the userspace about that as it is responsible
for the respect of this flag.
When a new connection is created and established, the Netlink events
now contain the existing but not currently used 'flags' attribute. When
MPTCP_PM_EV_FLAG_DENY_JOIN_ID0 is set, it means no other subflows
to the initial IP address and port -- info that are also part of the
event -- can be established.

The so-called fullmac devices rely on firmware functionality and/or API to
change BSS parameters. Today there are limited drivers supporting the
nl80211 primitive, but they only handle a subset of the bss parameters
passed if any. The mac80211 driver does handle all parameters and stores
their configured values. Some of the BSS parameters were already conditional
by wiphy->features. For these the wiphy->bss_param_support and wiphy->features
fields are silently aligned in wiphy_register(). Maybe better to issue a warning
instead when they are misaligned.

An S1G TIM PVB is encoded differently compared to a non-s1g TIM PVB.
As the AP dictates which encoding mode it uses, here we only implement
block bitmap encoding. This is the default encoding mode used by
all current vendor implementations.
Additionally, S1G has a maximum AID count of 8192, however we are
limiting the current implementation to 1600. This has no resemblence
to the standard and is purely an implementation detail. The reason for
this is due to the TIM elements maximum length of 255. This allows for,
at most, 25 encoded blocks for a PVB encoded with block bitmap. Support
for the maximum of 8192 AIDs will require an implementation of page slicing
to be added to mac80211.
As a result, we perform extra validation on both the STA and AP side
when receiving an AID as an S1G interface.
Add support for block bitmap encoding for an S1G AP and limit the
maximum AID count to 1600 for the current mac80211 implementations.

This new attribute is supposed to be used instead of NFTA_DEVICE_NAME
for simple wildcard interface specs. It holds a NUL-terminated string
representing an interface name prefix to match on.
While kernel code to distinguish full names from prefixes in
NFTA_DEVICE_NAME is simpler than this solution, reusing the existing
attribute with different semantics leads to confusion between different
versions of kernel and user space though:
* With old kernels, wildcards submitted by user space are accepted yet
silently treated as regular names.
* With old user space, wildcards submitted by kernel may cause crashes
since libnftnl expects NUL-termination when there is none.
Using a distinct attribute type sanitizes these situations as the
receiving part detects and rejects the unexpected attribute nested in
*_HOOK_DEVS attributes.

The uAPI stddef header includes compiler_types.h, a kernel-only
header, to make sure that kernel definitions of annotations
like __counted_by() take precedence.
There is a hack in scripts/headers_install.sh which strips includes
of compiler.h and compiler_types.h when installing uAPI headers.
While explicit handling makes sense for compiler.h, which is included
all over the uAPI, compiler_types.h is only included by stddef.h
(within the uAPI, obviously it's included in kernel code a lot).
Remove the stripping from scripts/headers_install.sh and wrap
the include of compiler_types.h in #ifdef __KERNEL__ instead.
This should be equivalent functionally, but is easier to understand
to a casual reader of the code. It also makes it easier to work
with kernel headers directly from under tools/

Enable configuration of the burst period — a time window starting
from the first error recovery, during which the reporter allows
recovery attempts for each reported error.
This feature is helpful when a single underlying issue causes multiple
errors, as it delays the start of the grace period to allow sufficient
time for recovering all related errors. For example, if multiple TX
queues time out simultaneously, a sufficient burst period could allow
all affected TX queues to be recovered within that window. Without this
period, only the first TX queue that reports a timeout will undergo
recovery, while the remaining TX queues will be blocked once the grace
period begins.
Configuration example:
$ devlink health set pci/0000:00:09.0 reporter tx burst_period 500
Configuration example with ynl:

regression. New user tools releases will not use such a mode,
the old release with a new kernel now will have warning about
deprecated behavior, and we prepare to remove this legacy mode
after about a year later
- The rename in kernel causing user tools build failure, revert
the rename in mdp_superblock_s
- Fix a regression that interrupted resync can be shown as
recover from mdstat or sysfs
- Improve file size detection for loop, particularly for networked
file systems, by using getattr to get the size rather than the
cached inode size.
- Hotplug CPU lock vs queue freeze fix
- Lockdep fix while updating the number of hardware queues
- Fix stacking for PI devices
- Silence bio_check_eod() for the known case of device removal where
the size is truncated to 0 sectors"

The security-version-number check should be used rather
than the runtime version check for driver updates.
Otherwise, the firmware update would fail when the update binary had
a lower runtime version number than the current one.

commit 907a99c314a5 ("md: rename recovery_cp to resync_offset") replaces
recovery_cp with resync_offset in mdp_superblock_s which is in md_p.h.
md_p.h is used in userspace too. So mdadm building fails because of this.
This patch revert this change.
