here is a resend of my series to lift the copy_from_user out of the individual sctp sockopt handlers into the main sctp_setsockopt routine. Changes since v1: - fixes a few sizeof calls. - use memzero_explicit in sctp_setsockopt_auth_key instead of special casing it for a kzfree in the caller - remove some minor cleanups from sctp_setsockopt_autoclose to keep it closer to the existing version - add another little only vaguely related cleanup patchThis is all very mechanical and contained to the sockopt code of SCTP, so I reviewed this a few times and applied it to net-next. Thanks Christoph!
Yep! And way easier to work with, function by function. Just for the records, Acked-by: Marcelo Ricardo Leitner <marcelo.leitner@gmail.com> Thanks.
