Jakub Kicinski 791a9ed0a4 netlink: specs: fou: replace underscores with dashes in names
We're trying to add a strict regexp for the name format in the spec.
Underscores will not be allowed, dashes should be used instead.
This makes no difference to C (codegen, if used, replaces special
chars in names) but it gives more uniform naming in Python.

Kory Maincent (Dent Project) eeb0c8f72f net: ethtool: Add PSE port priority support feature
This patch expands the status information provided by ethtool for PSE c33

Kory Maincent (Dent Project) ffef61d6d2 net: pse-pd: Add support for budget evaluation strategies
This patch introduces the ability to configure the PSE PI budget evaluation
strategies. Budget evaluation strategies is utilized by PSE controllers to
determine which ports to turn off first in scenarios such as power budget
exceedance.

The pis_prio_max value is used to define the maximum priority level
supported by the controller. Both the current priority and the maximum
priority are exposed to the user through the pse_ethtool_get_status call.

This patch add support for two mode of budget evaluation strategies.
1. Static Method:

   This method involves distributing power based on PD classification.
   It’s straightforward and stable, the PSE core keeping track of the
   budget and subtracting the power requested by each PD’s class.

   Advantages: Every PD gets its promised power at any time, which
   guarantees reliability.

   Disadvantages: PD classification steps are large, meaning devices
   request much more power than they actually need. As a result, the power
   supply may only operate at, say, 50% capacity, which is inefficient and
   wastes money.

   Priority max value is matching the number of PSE PIs within the PSE.

2. Dynamic Method:

   To address the inefficiencies of the static method, vendors like
   Microchip have introduced dynamic power budgeting, as seen in the
   PD692x0 firmware. This method monitors the current consumption per port
   and subtracts it from the available power budget. When the budget is
   exceeded, lower-priority ports are shut down.

   Advantages: This method optimizes resource utilization, saving costs.

   Disadvantages: Low-priority devices may experience instability.

   Priority max value is set by the PSE controller driver.

For now, budget evaluation methods are not configurable and cannot be
mixed. They are hardcoded in the PSE driver itself, as no current PSE
controller supports both methods.

Jakub Kicinski c6d732c38f net: ethtool: remove duplicate defines for family info
Commit under fixes switched to uAPI generation from the YAML
spec. A number of custom defines were left behind, mostly
for commands very hard to express in YAML spec.

Among what was left behind was the name and version of
the generic netlink family. Problem is that the codegen
always outputs those values so we ended up with a duplicated,
differently named set of defines.

Provide naming info in YAML and remove the incorrect defines.

to the "generic" TC action fields. This helps other actions include
the base fields without having to deal with nested structs.

A couple of actions (sample, gact) do not define extra fields,
so the spec used a common tc-gen struct for both of them.
Unfortunately this struct does not exist in C. Let's use gact's
(generic act's) struct for basic actions.

C codegen will soon use structs for binary types. A handful of structs

The structs are not part of uAPI, so we can't use them in C directly.
We could add them to the uAPI or add some annotation to tell the codegen
to output a local version to the user header. The former seems arbitrary
since we don't expose structs for most of the standard. The latter seems
like a lot of work for a rare occurrence. Drop the struct info for now.

Jiri Pirko 429ac62114 devlink: define enum for attr types of dynamic attributes
Devlink param and health reporter fmsg use attributes with dynamic type
which is determined according to a different type. Currently used values
are NLA_*. The problem is, they are not part of UAPI. They may change
which would cause a break.

To make this future safe, introduce a enum that shadows NLA_* values in
it and is part of UAPI.

Also, this allows to possibly carry types that are unrelated to NLA_*
values.

Kory Maincent 10c34b7d71 netlink: specs: ethtool: Remove UAPI duplication of phy-upstream enum
The phy-upstream enum is already defined in the ethtool.h UAPI header
and used by the ethtool userspace tool. However, the ethtool spec does
not reference it, causing YNL to auto-generate a duplicate and redundant
enum.

Fix this by updating the spec to reference the existing UAPI enum
in ethtool.h.

We started generating C code for OvS a while back, but actually
C codegen only supports fixed headers specified at the family
level right now (schema also allows specifying them per op).
ovs_flow and ovs_datapath already specify the fixed header
at the family level but ovs_vport does it per op.
Move the property, all ops use the same header.

This ensures YNL C sees the correct hdr_len:

   const struct ynl_family ynl_ovs_vport_family =  {
          .name           = "ovs_vport",

The rtnetlink family names are set to rt-$name within the YAML
but the files are called rt_$name. C codegen assumes that the
generated file name will match the family. The use of dashes
is in line with our general expectation that name properties
in the spec use dashes not underscores (even tho, as Donald
points out most genl families use underscores in the name).

We have 3 un-ideal options to choose from:

 - accept the slight inconsistency with old families using _, or
 - accept the slight annoyance with all languages having to do s/-/_/
   when looking up family ID, or
 - accept the inconsistency with all name properties in new YAML spec
   being separated with - and just the family name always using _.

Pick option 1 and rename the rtnl spec files.

Linus Torvalds b6dde1e527 NFSD 6.15 Release Notes
Neil Brown contributed more scalability improvements to NFSD's
 open file cache, and Jeff Layton contributed a menagerie of
 repairs to NFSD's NFSv4 callback / backchannel implementation.
 
 Mike Snitzer contributed a change to NFS re-export support that
 disables support for file locking on a re-exported NFSv4 mount.
 This is because NFSv4 state recovery is currently difficult if
 not impossible for re-exported NFS mounts. The change aims to
 prevent data integrity exposures after the re-export server
 crashes.
 
 Work continues on the evolving NFSD netlink administrative API.
 
 Many thanks to the contributors, reviewers, testers, and bug
 reporters who participated during the v6.15 development cycle.

  NFSD's NFSv4 callback / backchannel implementation.

  Mike Snitzer contributed a change to NFS re-export support that
  disables support for file locking on a re-exported NFSv4 mount. This
  is because NFSv4 state recovery is currently difficult if not
  impossible for re-exported NFS mounts. The change aims to prevent data
  integrity exposures after the re-export server crashes.

  Work continues on the evolving NFSD netlink administrative API.

  Many thanks to the contributors, reviewers, testers, and bug reporters
  who participated during the v6.15 development cycle"

Jeff Layton 9a28ac1762 lockd: add netlink control interface
The legacy rpc.nfsd tool will set the nlm_grace_period if the NFSv4
grace period is set. nfsdctl is missing this functionality, so add a new
netlink control interface for lockd that it can use. For now, it only
allows setting the grace period, and the tcp and udp listener ports.

lockd currently uses module parameters and sysctls for configuration, so
all of its settings are global. With this change, lockd now tracks these
values on a per-net-ns basis. It will only fall back to using the global
values if any of them are 0.

Finally, as a backward compatibility measure, if updating the nlm
settings in the init_net namespace, also update the legacy global
values to match.

Jakub Kicinski b5e489003a netdev: clarify GSO vs csum in qstats
Could be just me, but I had to pause and double check that the Tx csum
counter in qstat should include GSO'd packets. GSO pretty much implies
csum so one could possibly interpret the csum counter as pure csum offload.

But the counters are based on virtio:

  [tx_needs_csum]
      The number of packets which require checksum calculation by the device.

  [rx_needs_csum]
      The number of packets with VIRTIO_NET_HDR_F_NEEDS_CSUM.

and VIRTIO_NET_HDR_F_NEEDS_CSUM gets set on GSO packets virtio sends.

Clarify this in the spec to avoid any confusion.

Kory Maincent 6a774228e8 net: ethtool: tsconfig: Fix netlink type of hwtstamp flags
Fix the netlink type for hardware timestamp flags, which are represented
as a bitset of flags. Although only one flag is supported currently, the
correct netlink bitset type should be used instead of u32 to keep
consistency with other fields. Address this by adding a new named string
set description for the hwtstamp flag structure.

The code has been introduced in the current release so the uAPI change is
still okay.

Vladimir Oltean 6a128cdf19 net: ethtool: ts: add separate counter for unconfirmed one-step TX timestamps
For packets with two-step timestamp requests, the hardware timestamp
comes back to the driver through a confirmation mechanism of sorts,
which allows the driver to confidently bump the successful "pkts"
counter.

For one-step PTP, the NIC is supposed to autonomously insert its
hardware TX timestamp in the packet headers while simultaneously
transmitting it. There may be a confirmation that this was done
successfully, or there may not.

None of the current drivers which implement ethtool_ops :: get_ts_stats()
also support HWTSTAMP_TX_ONESTEP_SYNC or HWTSTAMP_TX_ONESTEP_SYNC, so it
is a bit unclear which model to follow. But there are NICs, such as DSA,
where there is no transmit confirmation at all. Here, it would be wrong /
misleading to increment the successful "pkts" counter, because one-step
PTP packets can be dropped on TX just like any other packets.

So introduce a special counter which signifies "yes, an attempt was made,
but we don't know whether it also exited the port or not". I expect that
for one-step PTP packets where a confirmation is available, the "pkts"
counter would be bumped.

Taehee Yoo eec8359f07 net: ethtool: add support for configuring hds-thresh
The hds-thresh option configures the threshold value of
the header-data-split.
If a received packet size is larger than this threshold value, a packet
will be split into header and payload.
The header indicates TCP and UDP header, but it depends on driver spec.
The bnxt_en driver supports HDS(Header-Data-Split) configuration at
FW level, affecting TCP and UDP too.
So, If hds-thresh is set, it affects UDP and TCP packets.

Example:
   # ethtool -G <interface name> hds-thresh <value>

   # ethtool -G enp14s0f0np0 tcp-data-split on hds-thresh 256
   # ethtool -g enp14s0f0np0
   Ring parameters for enp14s0f0np0:
   Pre-set maximums:
   ...
   HDS thresh:  1023
   Current hardware settings:
   ...
   TCP data split:         on
   HDS thresh:  256

The default/min/max values are not defined in the ethtool so the drivers
should define themself.
The 0 value means that all TCP/UDP packets' header and payload
will be split.

Jakub Kicinski 6ffdbb93a5 netlink: specs: rt_link: decode ip6tnl, vti and vti6 link attrs
Some of our tests load vti and ip6tnl so not being able to decode
the link attrs gets in the way of using Python YNL for testing.

Decode link attributes for ip6tnl, vti and vti6.

ip6tnl uses IFLA_IPTUN_FLAGS as u32, while ipv4 and sit expect
a u16 attribute, so we have a (first?) subset type override...

Two operations didn't have a small description. It looks like something
that has been missed in the original commit introducing this file.

Replace the two "todo" by a small and simple description: Create/Destroy
subflow.

While at it, also uniform the capital letters, avoid double spaces, and
fix the "announce" event description: a new "address" has been
announced, not a new "subflow".

The rendered version of the MPTCP events [1] looked strange, because the
whole content of the 'doc' was displayed in the same block.

It was then not clear that the first words, not even ended by a period,
were the attributes that are defined when such events are emitted. These
attributes have now been moved to the end, prefixed by 'Attributes:' and
ended with a period. Note that '>-' has been added after 'doc:' to allow
':' in the text below.
