netlink: specs: mptcp: fix port endianness

2024-09-12T03:42:47+00:00

The MPTCP port attribute is in host endianness, but was documented
as big-endian in the ynl specification.

Below are two examples from net/mptcp/pm_netlink.c showing that the
attribute is converted to/from host endianness for use with netlink.

Import from netlink:
  addr->port = htons(nla_get_u16(tb[MPTCP_PM_ADDR_ATTR_PORT]))

Export to netlink:
  nla_put_u16(skb, MPTCP_PM_ADDR_ATTR_PORT, ntohs(addr->port))

Where addr->port is defined as __be16.

No functional change intended.

ethtool: rss: echo the context number back

2024-07-25T23:23:47+00:00

The response to a GET request in Netlink should fully identify
the queried object. RSS_GET accepts context id as an input,
so it must echo that attribute back to the response.

After (assuming context 1 has been created):

  $ ./cli.py --spec netlink/specs/ethtool.yaml \
             --do rss-get \
	     --json '{"header": {"dev-index": 2}, "context": 1}'
  {'context': 1,
   'header': {'dev-index': 2, 'dev-name': 'eth0'},
  [...]

netlink: specs: correct the spec of ethtool

2024-07-25T23:23:47+00:00

The spec for Ethtool is a bit inaccurate. We don't currently
support dump. Context is only accepted as input and not echoed
to output (which is a separate bug).

Merge tag 'nfsd-6.11' of git://git.kernel.org/pub/scm/linux/kernel/git/cel/linux

2024-07-17T19:00:49+00:00

Pull nfsd updates from Chuck Lever:
 "This is a light release containing optimizations, code clean-ups, and
  minor bug fixes.

  This development cycle focused on work outside of upstream kernel
  development:

   - Continuing to build upstream CI for NFSD based on kdevops

   - Continuing to focus on the quality of NFSD in LTS kernels

   - Participation in IETF nfsv4 WG discussions about NFSv4 ACLs,
     directory delegation, and NFSv4.2 COPY offload

  Notable features for v6.11 that do not come through the NFSD tree
  include NFS server-side support for the new pNFS NVMe layout type
  [RFC9561]. Functional testing for pNFS block layouts like this one has
  been introduced to our kdevops CI harness. Work on improving the
  resolution of file attribute time stamps in local filesystems is also
  ongoing tree-wide.

  As always I am grateful to NFSD contributors, reviewers, testers, and
  bug reporters who participated during this cycle"

net/sched: flower: define new tunnel flags

2024-07-15T16:14:38+00:00

Define new TCA_FLOWER_KEY_FLAGS_* flags for use in struct
flow_dissector_key_control, covering the same flags as
currently exposed through TCA_FLOWER_KEY_ENC_FLAGS.

Put the new flags under FLOW_DIS_F_*. The idea is that we can
later, move the existing flags under FLOW_DIS_F_* as well.

The ynl flag names have been taken from the RFC iproute2 patch.
