Jakub Kicinski 2a98bc1316 genl: print caps for all families ... Back in 2006 kernel commit 334c29a64507 ("[GENETLINK]: Move command capabilities to flags.") removed some attributes and moved the capabilities to flags. Corresponding iproute2 commit 26328fc393 ("Add controller support for new features exposed") added the ability to print those caps. Printing is gated on version of the family, but we're checking the version of each individual family rather than the control family. The format of attributes in the control family is dictated by the version of the control family alone. In fact the entire version check is not strictly necessary. The code is not using the old attributes, so on older kernels it will simply print nothing either way. Families can't use flags for random things, because kernel core has a fixed interpretation. Thanks to this change caps will be shown for all families (assuming kernel newer than 2.6.19), not just those which by coincidence have their local version >= 2. For instance devlink, before: $ genl ctrl get name devlink Name: devlink ID: 0x15 Version: 0x1 header size: 0 max attribs: 179 commands supported: #1: ID-0x1 #2: ID-0x5 #3: ID-0x6 ... after: $ genl ctrl get name devlink Name: devlink ID: 0x15 Version: 0x1 header size: 0 max attribs: 179 commands supported: #1: ID-0x1 Capabilities (0xe): can doit; can dumpit; has policy #2: ID-0x5 Capabilities (0xe): can doit; can dumpit; has policy #3: ID-0x6 Capabilities (0xb): requires admin permission; can doit; has policy Fixes: 26328fc393 ("Add controller support for new features exposed") Signed-off-by: Jakub Kicinski <kuba@kernel.org> Reviewed-by: Jamal Hadi Salim <jhs@mojatatu.com> Signed-off-by: Stephen Hemminger <stephen@networkplumber.org>		2023-03-03 18:10:03 -08:00
