Module: kamailio Branch: master Commit: c5b8e5b3a82ac0f61a059f69921866952405ffe5 URL: https://github.com/kamailio/kamailio/commit/c5b8e5b3a82ac0f61a059f699218669… Author: Alex Hermann &lt;alex(a)hexla.nl&gt; Committer: Alex Hermann &lt;alex(a)hexla.nl&gt; Date: 2019-02-01T11:14:10+01:00 rr: Add new return value for preloaded route set to loose_route() Instead of returning just -1 (error), return a dedicated value. Now it is possible to detect from the script if a preloaded Route header was removed that pointed at the local proxy. The new return code is kept negative, so all code checking for failure response keeps working. --- Modified: src/modules/rr/doc/rr_admin.xml Modified: src/modules/rr/loose.c --- Diff: https://github.com/kamailio/kamailio/commit/c5b8e5b3a82ac0f61a059f699218669… Patch: https://github.com/kamailio/kamailio/commit/c5b8e5b3a82ac0f61a059f699218669… --- diff --git a/src/modules/rr/doc/rr_admin.xml b/src/modules/rr/doc/rr_admin.xml index 7dd1868e2a..74e59abe82 100644 --- a/src/modules/rr/doc/rr_admin.xml +++ b/src/modules/rr/doc/rr_admin.xml @@ -364,7 +364,7 @@ modparam("rr", "ignore_sips", 1) <listitem> <para><emphasis>2</emphasis> - route calculation based on - flow-token has been successful</para> + flow-token has been successful</para> </listitem> <listitem> @@ -376,6 +376,11 @@ modparam("rr", "ignore_sips", 1) <para><emphasis>-2</emphasis> - outbound flow-token shows evidence of tampering</para> </listitem> + + <listitem> + <para><emphasis>-3</emphasis> - next hop is taken from + a preloaded route set</para> + </listitem> </itemizedlist> <para>This function can be used from REQUEST_ROUTE.</para> diff --git a/src/modules/rr/loose.c b/src/modules/rr/loose.c index 6e9e888a2b..efe428a1cd 100644 --- a/src/modules/rr/loose.c +++ b/src/modules/rr/loose.c @@ -48,6 +48,7 @@ #define RR_OB_DRIVEN 2 /*!< The next hop is determined from the route set based on flow-token */ #define NOT_RR_DRIVEN -1 /*!< The next hop is not determined from the route set */ #define FLOW_TOKEN_BROKEN -2 /*!< Outbound flow-token shows evidence of tampering */ +#define RR_PRELOADED -3 /*!< The next hop is determined from a preloaded route set */ #define RR_ROUTE_PREFIX ROUTE_PREFIX "<" #define RR_ROUTE_PREFIX_LEN (sizeof(RR_ROUTE_PREFIX)-1) @@ -840,7 +841,7 @@ static inline int after_loose(struct sip_msg* _m, int preloaded) } if (res > 0) { /* No next route found */ LM_DBG("No next URI found\n"); - status = (preloaded ?
