We never increment the group number iterator, so all groups
get recorded into index 0 of the mcast_groups[] array.
As a result YNL can only handle using the last group.
For example using the "netdev" sample on kernel with
page pool commands results in:
$ ./samples/netdev
YNL: Multicast group 'mgmt' not found
Most families have only one multicast group, so this hasn't
been noticed. Plus perhaps developers usually test the last
group which would have worked.

During decoding of messages coming from kernel, attribute values are
converted to enum names in case the attribute type is enum of bitfield32.
However, when user constructs json message, he has to pass plain scalar
values. See "state" "selector" and "value" attributes in following
examples:
$ sudo ./tools/net/ynl/cli.py --spec Documentation/netlink/specs/dpll.yaml --do pin-set --json '{"id": 0, "parent-device": {"parent-id": 0, "state": 1}}'
$ sudo ./tools/net/ynl/cli.py --spec Documentation/netlink/specs/devlink.yaml --do port-set --json '{"bus-name": "pci", "dev-name": "0000:08:00.1", "port-index": 98304, "port-function": {"caps": {"selector": 1, "value": 1 }}}'
Allow user to pass strings containing enum names, convert them to scalar
values to be encoded into Netlink message:
$ sudo ./tools/net/ynl/cli.py --spec Documentation/netlink/specs/dpll.yaml --do pin-set --json '{"id": 0, "parent-device": {"parent-id": 0, "state": "connected"}}'
$ sudo ./tools/net/ynl/cli.py --spec Documentation/netlink/specs/devlink.yaml --do port-set --json '{"bus-name": "pci", "dev-name": "0000:08:00.1", "port-index": 98304, "port-function": {"caps": {"selector": ["roce-bit"], "value": ["roce-bit"] }}}'

There is one common error handler in ynl - ynl_cb_error().
It expects priv to be a pointer to struct ynl_parse_arg AKA yarg.
To avoid potential crashes if we encounter a stray NLMSG_ERROR
always pass yarg as priv (or a struct which has it as the first
member).
ynl_cb_null() has a similar problem directly - it expects yarg
but priv passed by the caller is ys.
Found by code inspection.

Make it possible for struct definitions to reference other struct
definitions ofr binary members. For example, the tbf qdisc uses this
struct definition for its parms attribute:
-
name: tc-tbf-qopt
type: struct
members:
-
name: rate
type: binary
struct: tc-ratespec
-
name: peakrate
type: binary
struct: tc-ratespec
-
name: limit
type: u32
-
name: buffer

-

No spaces wins in the kernel:
