Author: Andrei Pelinescu-Onciul <[email protected]> Committer: Andrei Pelinescu-Onciul <[email protected]> Date: Mon Mar 8 22:54:55 2010 +0100 tm: fix Reason generation for on-the-fly branch CANCELs For a canceled transaction, branches that have not received any reply might not have any pre-generated cancel buffers (in case cancel_b_method!=2). This could also happen when the first provisional response on a branch arrives in the same time with the event triggering the cancel (e.g. 2xx or 6xx on another branch, e2e cancel or timeout). In this cases, when generating the per-branch CANCEL for the first time (triggered by a received provisional reply), use the final transaction reply code as Reason. Note that this covers only the final reply triggered CANCEL case (2xx or 6xx received, local timeout or local script t_reply()) and it does not cover the e2e CANCEL case, for which either no reason will be generated (cancel_b_method == 1) or the reason might be 487 (cancel_b_method==0). --- modules/tm/t_msgbuilder.c | 2 ++ modules/tm/t_reply.c | 10 ++++++++-- 2 files changed, 10 insertions(+), 2 deletions(-) diff --git a/modules/tm/t_msgbuilder.c b/modules/tm/t_msgbuilder.c index a05fdbc..91a82f0 100644 --- a/modules/tm/t_msgbuilder.c +++ b/modules/tm/t_msgbuilder.c @@ -171,6 +171,7 @@ char *build_local(struct cell *Trans,unsigned int branch, *len+=CONTENT_LENGTH_LEN+1 + CRLF_LEN; reason_len = 0; reas1 = 0; + reas_last = 0; /* compute reason size (if no reason or disabled => reason_len == 0)*/ if (reason && reason->cause != CANCEL_REAS_UNKNOWN){ if (likely(reason->cause > 0 && @@ -307,6 +308,7 @@ char *build_local_reparse(struct cell *Trans,unsigned int branch, reason_len = 0; reas1 = 0; + reas_last = 0; /* compute reason size (if no reason or disabled => reason_len == 0)*/ if (reason && reason->cause != CANCEL_REAS_UNKNOWN){ if (likely(reason->cause > 0 && diff --git a/modules/tm/t_reply.c b/modules/tm/t_reply.c index 6ee3fae..6bcef61 100644 --- a/modules/tm/t_reply.c +++ b/modules/tm/t_reply.c @@ -2043,8 +2043,14 @@ int reply_received( struct sip_msg *p_msg ) DBG("tm: reply_received: branch CANCEL created\n"); /* note that in this case we do not know the reason (it could be a final reply or a received cancel) - and we don't want to wait for it => no reason */ - cancel_branch(t, branch, 0, F_CANCEL_B_FORCE_C); + and we don't want to wait for it.
