Module: kamailio Branch: master Commit: 42351ec91b38ce3f8eff51978d00010f54481924 URL: https://github.com/kamailio/kamailio/commit/42351ec91b38ce3f8eff51978d00010… Author: Wolfgang Kampichler &lt;dev(a)kampichler.info&gt; Committer: Wolfgang Kampichler &lt;dev(a)kampichler.info&gt; Date: 2023-04-26T17:56:23+02:00 lost: P-A-I parsing with display name fixed (#3426) - this fix improves P-Asserted-Identity parsing to properly extract the uri from the header value. The uri (sip/tel) is used as identity for HELD requests. --- Modified: src/modules/lost/utilities.c --- Diff: https://github.com/kamailio/kamailio/commit/42351ec91b38ce3f8eff51978d00010… Patch: https://github.com/kamailio/kamailio/commit/42351ec91b38ce3f8eff51978d00010… --- diff --git a/src/modules/lost/utilities.c b/src/modules/lost/utilities.c index f86fcaf015..6f50329574 100644 --- a/src/modules/lost/utilities.c +++ b/src/modules/lost/utilities.c @@ -477,50 +477,45 @@ p_lost_geolist_t lost_get_geolocation_header(struct sip_msg *msg, int *items) */ char *lost_get_pai_header(struct sip_msg *msg, int *lgth) { - p_id_body_t *p_body; - - char *tmp = NULL; + to_body_t *p_pai; char *res = NULL; - int len = 0; *lgth = 0; - if(parse_pai_header(msg) == -1) { - - LM_DBG("failed to parse P-A-I header\n"); - - return res; - } + if((parse_pai_header(msg) == 0) && (msg->pai) && (msg->pai->parsed)) { + /* return the first header entry */ + p_pai = get_pai(msg)->id; + if((p_pai->parsed_uri.user.s == NULL) + && (parse_uri(p_pai->uri.s, p_pai->uri.len, &p_pai->parsed_uri) + < 0)) { + + LM_DBG("failed to parse P-A-I header\n"); + + return res; + } + } else { + + LM_DBG("P-A-I header not found or failed to parse\n"); - if(msg->pai == NULL || get_pai(msg) == NULL) { - LM_ERR("P-A-I header not found\n"); return res; } - p_body = get_pai(msg); - /* warning in case multiple P-A-I headers were found and use first */ - if(p_body->num_ids > 1) { - LM_WARN("multiple P-A-I headers found, selecting first!\n"); + /* warning in case multiple P-A-I headers were found */ + if(get_pai(msg)->num_ids > 1) { + LM_WARN("multiple P-A-I headers found, selected first!\n"); } - LM_DBG("P-A-I body: [%.*s]\n", p_body->id->body.len, p_body->id->body.s); + LM_DBG("P-A-I uri: [%.*s]\n", p_pai->uri.len, p_pai->uri.s); - /* accept any identity string (body), but remove <..> if present */ - tmp = p_body->id->body.s; - len = p_body->id->body.len; - if(tmp[0] == '<' && tmp[len - 1] == '>') { - tmp++; - len -= 2; - } /* allocate memory, copy and \0 terminate string */ - res = (char *)pkg_malloc((len + 1) * sizeof(char)); + res = (char *)pkg_malloc((p_pai->uri.len + 1) * sizeof(char)); if(res == NULL) { PKG_MEM_ERROR; return res; } else { - memset(res, 0, len); - memcpy(res, tmp, len); - res[len] = '\0'; + memset(res, 0, p_pai->uri.len); + memcpy(res, p_pai->uri.s, p_pai->uri.len); + res[p_pai->uri.len] = '\0'; *lgth = strlen(res); }
