This patchset adds a 'sub-message' attribute type to the netlink-raw
schema and implements it in ynl. This provides support for kind-specific
options attributes as used in rt_link and tc raw netlink families.
A description of the new 'sub-message' attribute type and the
corresponding sub-message definitions is provided in patch 2.
The patchset includes updates to the rt_link spec and a new tc spec that
make use of the new 'sub-message' attribute type.
Patch 1 adds missing scalar types to the netlink-raw schema
Patch 2 and 3 add sub-message support to the schema and ynl
Patch 4 adds binary and pad support to structs in netlink-raw
Patches 5 and 6 contain specs that use the sub-message attribute type

The netlink-raw schema was not updated when bitfield32 was added
to the genetlink-legacy schema. It is needed for rtnetlink families.
s8 and s16 were also missing.

Add a 'sub-message' attribute type with a selector that supports
polymorphic attribute formats for raw netlink families like tc.
A sub-message attribute uses the value of another attribute as a
selector key to choose the right sub-message format. For example if the
following attribute has already been decoded:
{ "kind": "gre" }
and we encounter the following attribute spec:
-
name: data
type: sub-message
sub-message: linkinfo-data-msg
selector: kind
Then we look for a sub-message definition called 'linkinfo-data-msg' and
use the value of the 'kind' attribute i.e. 'gre' as the key to choose
the correct format for the sub-message:
sub-messages:
name: linkinfo-data-msg
formats:
-
value: bridge
attribute-set: linkinfo-bridge-attrs
-
value: gre
attribute-set: linkinfo-gre-attrs
-
value: geneve
attribute-set: linkinfo-geneve-attrs
This would decode the attribute value as a sub-message with the
attribute-set called 'linkinfo-gre-attrs' as the attribute space.
A sub-message can have an optional 'fixed-header' followed by zero or
more attributes from an attribute-set. For example the following
'tc-options-msg' sub-message defines message formats that use a mixture
of fixed-header, attribute-set or both together:
sub-messages:
-
name: tc-options-msg
formats:
-
value: bfifo
fixed-header: tc-fifo-qopt
-
value: cake
attribute-set: tc-cake-attrs
-
value: netem
fixed-header: tc-netem-qopt
attribute-set: tc-netem-attrs

Implement the 'sub-message' attribute type in ynl.
Encode support is not yet implemented. Support for sub-message selectors
at a different nest level from the key attribute is not yet supported.

Switch to using a sub-message selector in the rt_link spec for the
link-specific 'data' attribute.

This is a work-in-progress spec for tc that covers:
- most of the qdiscs
- the flower classifier
- new, del, get for qdisc, chain, class and filter
Notable omissions:
- most of the stats attrs are left as binary blobs
- notifications are not yet implemented

Let me apply this one already, it's kinda independent.

SGTM, could you add all the info from the commit message somewhere
in the documentation? Perhaps a new section at the end of

We can leave it for later either way, but have you seen any selectors
which would key on an integer, rather than a string?

Looks unrelated, plus the 'for' vs 'if' are still indented by 2.

Nice reuse of the concept of "pad", I don't see why not:

What does Python style guide say about spaces around '+' here?
I tend to use C style, no idea if it's right.

Just to be clear - we can define sub-message for this nest, too, right?
Not sure if it's worth moving the comment in the commit, it's just
noise..

Ugh. Meaning the selector is at a "previous" level of nesting?

Should we add sub-messages to tools/net/ynl/ynl-gen-rst.py ?
Does the output look sane with the new attributes?

From what I have seen, I am fairly sure it's always going to be a
string. (famous last words)

The relevant section seems to be this:
However, in a slice the colon acts like a binary operator, and should
have equal amounts on either side (treating it as the operator with
the lowest priority). In an extended slice, both colons must have the
same amount of spacing applied. Exception: when a slice parameter is
omitted, the space is omitted:
# Correct:
ham[1:9], ham[1:9:3], ham[:9:3], ham[1::3], ham[1:9:]
ham[lower:upper], ham[lower:upper:], ham[lower::step]
ham[lower+offset : upper+offset]
ham[: upper_fn(x) : step_fn(x)], ham[:: step_fn(x)]
ham[lower + offset : upper + offset]
# Wrong:
ham[lower + offset:upper + offset]
ham[1: 9], ham[1 :9], ham[1:9 :3]
ham[lower : : step]
ham[ : upper]
On that basis I could change it to:
(a) value = msg.raw[offset : offset+m.len]
or:
(b) value = msg.raw[offset : offset + m.len]
But the existing convention in the code is a mix of these styles:
raw[offset:offset + 4]
raw[offset:offset+m['len']]
Happy to go with whatever preference, though maximising whitespace per
(b) follows python style _and_ C style?
Also happy to make it consistent across the file (in a separate patch)?

Ah, good catch. I can at least put in a sub-message placeholder for
slave-data.

That's right. I wonder if we should use a relative syntax like "../kind"
for the selector. Will either need to pass the known attrs to nest
parsing, or pass a resolver instead?

Yup, style (b) does look the least surprising to my C-accustomed eyes,
so +1 on using that.

Follow up cleanup sounds good!

../kind is my first thought, too.
But on reflection I reckon it may make the codegen and Python parser
quite a bit more complex. :S
Passing in known selector attrs to nests sounds good. Assuming we never
have to do something like: "../other-nest/attr".
Or perhaps in that case we can support passing in nested attrs, just
not backtracking? Backtracking is the hard part, really. Yeah, that
sounds simplest, at least at the "thought exercise level" :)
What would "resolver" look like?
BTW how do we deal with ordering. Do we require that selector attr
must be present in the message before the submsg? I think in practice
is should always be the case, but we should document that.

Improving looks is 100% fine as a follow up.
But do check we don't break rendering completely for stuff we should
already support when sub-messages appear.

That was my main concern with it too.
Another thought I had was to explicitly mark attrs that get used as
selector keys, but I don't think that actually buys us anything.

I was thinking a resolver would be a class with a single lookup method
that internally holds attributes from the current scope and has a parent
it can delegate to. It would try to resolve e.g. "kind" in current scope
then, on failure, delegate to its parent. When recursing to decode a
submsg, create a new resolver with the current one as its parent.
If we did it this way, there'd be no need for "../kind".

The selector attr is de-facto present in the message before it is
needed, both at the same level and for sub messages. So, yeah, I think
we require this and agreed we should document it. I will do that in
the next revision.
From what I have seen so far, selector attrs are at same level or at
root level, but I'm not confident that will hold true for all of the raw
families.
