From 884d8c53e68bdbeb520acf5a226161d960898873 Mon Sep 17 00:00:00 2001 From: Michael Tuexen Date: Wed, 24 Aug 2016 06:22:53 +0000 Subject: [PATCH] When aborting an association, send the ABORT before notifying the upper layer. For the kernel this doesn't matter, for the userland stack, it does. While there, silence a clang warning when compiling it in userland. --- sys/netinet/sctputil.c | 16 ++++++++-------- 1 file changed, 8 insertions(+), 8 deletions(-) diff --git a/sys/netinet/sctputil.c b/sys/netinet/sctputil.c index 4d5d497c296..6eb9e239399 100644 --- a/sys/netinet/sctputil.c +++ b/sys/netinet/sctputil.c @@ -3983,17 +3983,16 @@ sctp_abort_association(struct sctp_inpcb *inp, struct sctp_tcb *stcb, vtag = 0; if (stcb != NULL) { - /* We have a TCB to abort, send notification too */ vtag = stcb->asoc.peer_vtag; - sctp_abort_notification(stcb, 0, 0, NULL, SCTP_SO_NOT_LOCKED); - /* get the assoc vrf id and table id */ vrf_id = stcb->asoc.vrf_id; - stcb->asoc.state |= SCTP_STATE_WAS_ABORTED; } sctp_send_abort(m, iphlen, src, dst, sh, vtag, op_err, mflowtype, mflowid, inp->fibnum, vrf_id, port); if (stcb != NULL) { + /* We have a TCB to abort, send notification too */ + sctp_abort_notification(stcb, 0, 0, NULL, SCTP_SO_NOT_LOCKED); + stcb->asoc.state |= SCTP_STATE_WAS_ABORTED; /* Ok, now lets free it */ #if defined(__APPLE__) || defined(SCTP_SO_LOCK_TESTING) so = SCTP_INP_SO(inp); @@ -4109,10 +4108,6 @@ sctp_abort_an_association(struct sctp_inpcb *inp, struct sctp_tcb *stcb, } else { stcb->asoc.state |= SCTP_STATE_WAS_ABORTED; } - /* notify the ulp */ - if ((inp->sctp_flags & SCTP_PCB_FLAGS_SOCKET_GONE) == 0) { - sctp_abort_notification(stcb, 0, 0, NULL, so_locked); - } /* notify the peer */ sctp_send_abort_tcb(stcb, op_err, so_locked); SCTP_STAT_INCR_COUNTER32(sctps_aborted); @@ -4120,6 +4115,10 @@ sctp_abort_an_association(struct sctp_inpcb *inp, struct sctp_tcb *stcb, (SCTP_GET_STATE(&stcb->asoc) == SCTP_STATE_SHUTDOWN_RECEIVED)) { SCTP_STAT_DECR_GAUGE32(sctps_currestab); } + /* notify the ulp */ + if ((inp->sctp_flags & SCTP_PCB_FLAGS_SOCKET_GONE) == 0) { + sctp_abort_notification(stcb, 0, 0, NULL, so_locked); + } /* now free the asoc */ #ifdef SCTP_ASOCLOG_OF_TSNS sctp_print_out_track_log(stcb); @@ -6400,6 +6399,7 @@ sctp_connectx_helper_find(struct sctp_inpcb *inp, struct sockaddr *addr, #endif default: *totaddr = i; + incr = 0; /* we are done */ break; }
