terminator.\n\nEither this needs to switch to nla_strcmp() and needs to adjust printf fmt\nspecifier to not use plain %s, or this needs to use NLA_NUL_STRING.\n\nAs the code has been this way for long time, it seems to me that userspace\ndoes include the terminating nul, even tough its not enforced so far, and\nthus NLA_NUL_STRING use is the simpler solution."}], "lastModified":
