Jakub Kicinski 4cd2796f3f tools: ynl: support pretty printing bad attribute names ... One of my favorite features of the Netlink specs is that they make decoding structured extack a ton easier. Implement pretty printing bad attribute names in YNL. For example it will now say: 'bad-attr': '.header.flags' rather than the useless: 'bad-attr-offs': 32 Proof: $ ./cli.py --spec ethtool.yaml --do rings_get \ --json '{"header":{"dev-index":1, "flags":4}}' Netlink error: Invalid argument nl_len = 68 (52) nl_flags = 0x300 nl_type = 2 error: -22 extack: {'msg': 'reserved bit set', 'bad-attr': '.header.flags'} Signed-off-by: Jakub Kicinski <kuba@kernel.org>		2023-01-31 20:36:03 -08:00
