net: ynl: prefix uAPI header include with uapi/

2023-05-26T09:30:14+00:00

To keep things simple we used to include the uAPI header
in the kernel in the #include  format.
This works well enough, most of the genl families should
have headers in include/net/ so linux/$family.h ends up
referring to the uAPI header, anyway. And if it doesn't
no big deal, we'll just include more info than we need.

Unless that is there is a naming conflict. Someone recently
created include/linux/psp.h which will be a problem when
supporting the PSP protocol. (I'm talking about
work-in-progress patches, but it's just a proof that assuming
lack of name conflicts was overly optimistic.)

tools: ynl: skip the explicit op array size when not needed

2023-03-22T04:45:31+00:00

Jiri suggests it reads more naturally to skip the explicit
array size when possible. When we export the symbol we want
to make sure that the size is right but for statics its
not needed.

ynl: broaden the license even more

2023-03-17T04:20:32+00:00

I relicensed Netlink spec code to GPL-2.0 OR BSD-3-Clause but
we still put a slightly different license on the uAPI header
than the rest of the code. Use the Linux-syscall-note on all
the specs and all generated code. It's moot for kernel code,
but should not hurt. This way the licenses match everywhere.

ynl: re-license uniformly under GPL-2.0 OR BSD-3-Clause

2023-03-07T21:44:30+00:00

I was intending to make all the Netlink Spec code BSD-3-Clause
to ease the adoption but it appears that:
 - I fumbled the uAPI and used "GPL WITH uAPI note" there
 - it gives people pause as they expect GPL in the kernel
As suggested by Chuck re-license under dual. This gives us benefit
of full BSD freedom while fulfilling the broad "kernel is under GPL"
expectations.

netdev-genl: create a simple family for netdev stuff

2023-02-03T04:48:23+00:00

Add a Netlink spec-compatible family for netdevs.
This is a very simple implementation without much
thought going into it.

It allows us to reap all the benefits of Netlink specs,
one can use the generic client to issue the commands:

  $ ./cli.py --spec netdev.yaml --dump dev_get
  [{'ifindex': 1, 'xdp-features': set()},
   {'ifindex': 2, 'xdp-features': {'basic', 'ndo-xmit', 'redirect'}},
   {'ifindex': 3, 'xdp-features': {'rx-sg'}}]

the generic python library does not have flags-by-name
support, yet, but we also don't have to carry strings
in the messages, as user space can get the names from
the spec.
