tools/net/ynl: Report netlink errors without stacktrace
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 <module> 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 <donald.hunter@gmail.com> Link: https://lore.kernel.org/r/20240306231046.97158-3-donald.hunter@gmail.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>
