There are multiple places doing same/similar calculations and updating them is error prone as one spot can easily be left out. This patchset converges it into a more concise and consistent code. In general, it moves MTU handling from functions with bigger objectives, such as sctp_assoc_add_peer(), to specific functions. It's also a preparation for the next patchset, which removes the duplication between sctp_make_op_error_space and sctp_make_op_error_fixed and relies on sctp_mtu_payload introduced here. More details on each patch. Marcelo Ricardo Leitner (13): sctp: remove old and unused SCTP_MIN_PMTU sctp: move transport pathmtu calc away of sctp_assoc_add_peer sctp: remove an if() that is always true sctp: introduce sctp_assoc_set_pmtu sctp: introduce sctp_mtu_payload sctp: introduce sctp_assoc_update_frag_point sctp: remove sctp_assoc_pending_pmtu sctp: introduce sctp_dst_mtu sctp: remove sctp_transport_pmtu_check sctp: re-use sctp_transport_pmtu in sctp_transport_route sctp: honor PMTU_DISABLED when handling icmp sctp: consider idata chunks when setting SCTP_MAXSEG sctp: allow unsetting sockopt MAXSEG include/net/sctp/constants.h | 5 ++-- include/net/sctp/sctp.h | 52 ++++++++++++++------------------------ include/net/sctp/structs.h | 2 ++ net/sctp/associola.c | 60 +++++++++++++++++++++++--------------------- net/sctp/chunk.c | 12 +-------- net/sctp/output.c | 28 ++++++++------------- net/sctp/socket.c | 43 ++++++++++++++----------------- net/sctp/transport.c | 37 ++++++++++++++------------- 8 files changed, 105 insertions(+), 134 deletions(-)
