2023-01-31tools: ynl-gen: prevent do / dump reorderingJakub Kicinski
An earlier fix tried to address generated code jumping around one code-gen run to another. Turns out dict()s are already ordered since Python 3.7, the problem is that we iterate over operation modes using a set(). Sets are unordered in Python. Signed-off-by: Jakub Kicinski <kuba@kernel.org>
2023-01-26tools: ynl: store ops in ordered dict to avoid random orderingJakub Kicinski
When rendering code we should walk the ops in the order in which they are declared in the spec. This is both more intuitive and prevents code from jumping around when hashing in the dict changes. Signed-off-by: Jakub Kicinski <kuba@kernel.org>
2023-01-26tools: ynl: rename ops_list -> msg_listJakub Kicinski
ops_list contains all the operations, but the main iteration use case is to walk only ops which define attrs. Rename ops_list to msg_list, because now it looks like the contents are the same, just the format is different. While at it convert from tuple to just keys, none of the users care about the name of the op. Signed-off-by: Jakub Kicinski <kuba@kernel.org>
2023-01-26tools: ynl: support kdocs for flags in code generationJakub Kicinski
Lorenzo reports that after switching from enum to flags netdev family lost ability to render kdoc (and the enum contents got generally garbled). Combine the flags and enum handling in uAPI handling. Reported-by: Lorenzo Bianconi <lorenzo@kernel.org> Signed-off-by: Jakub Kicinski <kuba@kernel.org>
2023-01-24tools: ynl: add a completely generic clientJakub Kicinski
Add a CLI sample which can take in arbitrary request in JSON format, convert it to Netlink and do the inverse for output. It's meant as a development tool primarily and perhaps for selftests which need to tickle netlink in a special way.

2023-01-24net: add basic C code generators for NetlinkJakub Kicinski
Code generators to turn Netlink specs into C code. I'm definitely not proud of it. The main generator is in Python, there's a bash script to regen all code-gen'ed files in tree after making spec changes.
