(#3137) * acc: Fix reason code for locally generated replies. - Use heap memory for the reason code instead of the stack memory. - See issue #2981 * acc: Remove code which was commented out. - Code was commented out in the previous pull request. (#3137). - This has now been corrected. --- Modified: src/modules/acc/acc_logic.c --- Diff: https://github.com/kamailio/kamailio/commit/e74cb2371ab879874a8981818139024… Patch: https://github.com/kamailio/kamailio/commit/e74cb2371ab879874a8981818139024… --- diff --git a/src/modules/acc/acc_logic.c b/src/modules/acc/acc_logic.c index e045b8c95ac..169a4222fbf 100644 --- a/src/modules/acc/acc_logic.c +++ b/src/modules/acc/acc_logic.c @@ -93,25 +93,20 @@ void env_set_totag(struct cell *t, struct sip_msg *reply) tmb.t_get_reply_totag(t->uas.request, &acc_env.to_tag); } -int env_set_reason(struct sip_msg *reply, str *buff) { - int i; - char *p; +int env_set_reason(struct sip_msg *reply, str *buff, int code) { + if (reply!=FAKED_REPLY || !buff || !buff->s || buff->len < 20) return 0; if (strncmp(buff->s, "SIP/2.0 ", 8) != 0) { LM_ERR("not a SIP reply\n"); return 0; } - p = buff->s + 12; - for (i=12;i<buff->len;i++) { - if (*p == '\r' || *p == '\n') { - acc_env.reason.s = buff->s+12; - acc_env.reason.len = i-12; - LM_DBG("reason[%.*s]\n", acc_env.reason.len, acc_env.reason.s); - return 1; - } - p++; - } + + /* Set the reason to a pointer in heap memory.
