tools/net/ynl: Report netlink errors without stacktrace

2024-03-08T04:28:26Z

ynl does not handle NlError exceptions so they get reported like program failures. Handle the NlError exceptions and report the netlink errors more cleanly. Example now: Netlink error: No such file or directory nl_len = 44 (28) nl_flags = 0x300 nl_type = 2 error: -2 extack: {'bad-attr': '.op'} Example before: Traceback (most recent call last): File "/home/donaldh/net-next/./tools/net/ynl/cli.py", line 81, in main() File "/home/donaldh/net-next/./tools/net/ynl/cli.py", line 69, in main reply = ynl.dump(args.dump, attrs) ^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/home/donaldh/net-next/tools/net/ynl/lib/ynl.py", line 906, in dump return self._op(method, vals, [], dump=True) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/home/donaldh/net-next/tools/net/ynl/lib/ynl.py", line 872, in _op raise NlError(nl_msg) lib.ynl.NlError: Netlink error: No such file or directory nl_len = 44 (28) nl_flags = 0x300 nl_type = 2 error: -2 extack: {'bad-attr': '.op'} Signed-off-by: Donald Hunter Link: https://lore.kernel.org/r/20240306231046.97158-3-donald.hunter@gmail.com Signed-off-by: Jakub Kicinski

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

2023-03-07T21:44:30Z

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.

tools: ynl: add an object hierarchy to represent parsed spec

2023-02-01T04:36:03Z

There's a lot of copy and pasting going on between the "cli" and code gen when it comes to representing the parsed spec. Create a library which both can use. Signed-off-by: Jakub Kicinski
