Commit 5b4e9a7a71ab ("net: ethtool: extend ringparam set/get APIs for rx_push")
added a new attr for configuring rx-push, right after tx-push.
Add it to the spec, the ring param operation is covered by
the otherwise sparse ethtool spec.

We've added 96 non-merge commits during the last 14 day(s) which contain

There is a minor conflict in drivers/net/ethernet/intel/ice/ice_main.c
between commit 5b246e533d01 ("ice: split probe into smaller functions")
from the net-next tree and commit 66c0e13ad236 ("drivers: net: turn on
XDP features") from the bpf-next tree. Remove the hunk given ice_cfg_netdev()
is otherwise there a 2nd time, and add XDP features to the existing
ice_cfg_netdev() one:
[...]
ice_set_netdev_features(netdev);
netdev->xdp_features = NETDEV_XDP_ACT_BASIC | NETDEV_XDP_ACT_REDIRECT |
NETDEV_XDP_ACT_XSK_ZEROCOPY;
ice_set_ops(netdev);
[...]
Stephen's merge conflict mail:
https://lore.kernel.org/bpf/20230207101951.21a114fa@canb.auug.org.au/
The main changes are:
1) Add support for BPF trampoline on s390x which finally allows to remove many
test cases from the BPF CI's DENYLIST.s390x, from Ilya Leoshkevich.
2) Add multi-buffer XDP support to ice driver, from Maciej Fijalkowski.
3) Add capability to export the XDP features supported by the NIC.
Along with that, add a XDP compliance test tool,
from Lorenzo Bianconi & Marek Majtyka.
4) Add __bpf_kfunc tag for marking kernel functions as kfuncs,
from David Vernet.
5) Add a deep dive documentation about the verifier's register
liveness tracking algorithm, from Eduard Zingerman.
6) Fix and follow-up cleanups for resolve_btfids to be compiled
as a host program to avoid cross compile issues,
from Jiri Olsa & Ian Rogers.
7) Batch of fixes to the BPF selftest for xdp_hw_metadata which resulted
when testing on different NICs, from Jesper Dangaard Brouer.
8) Fix libbpf to better detect kernel version code on Debian, from Hao Xiang.
9) Extend libbpf to add an option for when the perf buffer should
wake up, from Jon Doron.
10) Follow-up fix on xdp_metadata selftest to just consume on TX
completion, from Stanislav Fomichev.
11) Extend the kfuncs.rst document with description on kfunc
lifecycle & stability expectations, from David Vernet.
12) Fix bpftool prog profile to skip attaching to offline CPUs,
from Tonghao Zhang.

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.

Ethtool is one of the most actively developed families.
With the changes to the CLI it should be possible to use
the YNL based code for easy prototyping and development.
Add a partial family definition. I've tested the string
set and rings. I don't have any MAC Merge implementation
to test with, but I added the definition for it, anyway,
because it's last. New commands can simply be added at
the end without having to worry about manually providing
IDs / values.
Set (with notification support - None is the response,
the data is from the notification):
$ sudo ./tools/net/ynl/cli.py \
--spec Documentation/netlink/specs/ethtool.yaml \
--do rings-set \
--json '{"header":{"dev-name":"enp0s31f6"}, "rx":129}' \
--subscribe monitor
None
[{'msg': {'header': {'dev-index': 2, 'dev-name': 'enp0s31f6'},
'rx': 136,
'rx-max': 4096,
'tx': 256,
'tx-max': 4096,
'tx-push': 0},
'name': 'rings-ntf'}]
Do / dump (yes, the kernel requires that even for dump and even
if empty - the "header" nest must be there):
$ ./tools/net/ynl/cli.py \
--spec Documentation/netlink/specs/ethtool.yaml \
--do rings-get \
--json '{"header":{"dev-index": 2}}'
{'header': {'dev-index': 2, 'dev-name': 'enp0s31f6'},
'rx': 136,
'rx-max': 4096,
'tx': 256,
'tx-max': 4096,
'tx-push': 0}
$ ./tools/net/ynl/cli.py \
--spec Documentation/netlink/specs/ethtool.yaml \
--dump rings-get \
--json '{"header":{}}'
[{'header': {'dev-index': 2, 'dev-name': 'enp0s31f6'},
'rx': 136,
'rx-max': 4096,
'tx': 256,
'tx-max': 4096,
'tx-push': 0},
{'header': {'dev-index': 3, 'dev-name': 'wlp0s20f3'}, 'tx-push': 0},
{'header': {'dev-index': 19, 'dev-name': 'enp58s0u1u1'},
'rx': 100,
'rx-max': 4096,
'tx-push': 0}]
And error reporting:
$ ./tools/net/ynl/cli.py \
--spec Documentation/netlink/specs/ethtool.yaml \
--dump rings-get \
--json '{"header":{"flags":5}}'
Netlink error: Invalid argument
nl_len = 68 (52) nl_flags = 0x300 nl_type = 2
error: -22 extack: {'msg': 'reserved bit set',
'bad-attr-offs': 24,
'bad-attr': '.header.flags'}
None

I had a (bright?) idea of introducing the concept of enum-models
to account for all the weird ways families enumerate their messages.
I've never finished it because generating C code for each of them
is pretty daunting. But for languages which can use ID values directly
the support is simple enough, so clean this up a bit.
"unified" model is what I recommend going forward.
"directional" model is what ethtool uses.
"notify-split" is used by the proposed DPLL code, but we can just
make them use "unified", it hasn't been merged :)

Add schemas for Netlink spec files. As described in the docs
we have 4 "protocols" or compatibility levels, and each one
comes with its own schema, but the more general / legacy
schemas are superset of more modern ones: genetlink is
the smallest followed by genetlink-c and genetlink-legacy.
There is no schema for raw netlink, yet, I haven't found the time..
I don't know enough jsonschema to do inheritance or something
but the repetition is not too bad. I hope.
