From edcba4e307fc6d8cf3de5d22982b1317178e7433 Mon Sep 17 00:00:00 2001 From: Harald Welte Date: Sun, 17 Jun 2012 23:34:34 +0800 Subject: use new external libosmogb (part of libosmocore.git) This removes the libgb (GPRS NS/BSSGP) code from the openbsc.git repository and uses the new version from libosmocore.git instead. --- openbsc/include/osmocom/gprs/gprs_ns.h | 189 --------------------------------- 1 file changed, 189 deletions(-) delete mode 100644 openbsc/include/osmocom/gprs/gprs_ns.h (limited to 'openbsc/include/osmocom/gprs/gprs_ns.h') diff --git a/openbsc/include/osmocom/gprs/gprs_ns.h b/openbsc/include/osmocom/gprs/gprs_ns.h deleted file mode 100644 index a7f32b25a..000000000 --- a/openbsc/include/osmocom/gprs/gprs_ns.h +++ /dev/null @@ -1,189 +0,0 @@ -#ifndef _GPRS_NS_H -#define _GPRS_NS_H - -#include - -/* Our Implementation */ -#include -#include -#include -#include -#include -#include - -#include - -#define NS_TIMERS_COUNT 7 -#define NS_TIMERS "(tns-block|tns-block-retries|tns-reset|tns-reset-retries|tns-test|tns-alive|tns-alive-retries)" -#define NS_TIMERS_HELP \ - "(un)blocking Timer (Tns-block) timeout\n" \ - "(un)blocking Timer (Tns-block) number of retries\n" \ - "Reset Timer (Tns-reset) timeout\n" \ - "Reset Timer (Tns-reset) number of retries\n" \ - "Test Timer (Tns-test) timeout\n" \ - "Alive Timer (Tns-alive) timeout\n" \ - "Alive Timer (Tns-alive) number of retries\n" - -enum ns_timeout { - NS_TOUT_TNS_BLOCK, - NS_TOUT_TNS_BLOCK_RETRIES, - NS_TOUT_TNS_RESET, - NS_TOUT_TNS_RESET_RETRIES, - NS_TOUT_TNS_TEST, - NS_TOUT_TNS_ALIVE, - NS_TOUT_TNS_ALIVE_RETRIES, -}; - -#define NSE_S_BLOCKED 0x0001 -#define NSE_S_ALIVE 0x0002 - -/*! \brief Osmocom NS link layer types */ -enum gprs_ns_ll { - GPRS_NS_LL_UDP, /*!< NS/UDP/IP */ - GPRS_NS_LL_E1, /*!< NS/E1 */ - GPRS_NS_LL_FR_GRE, /*!< NS/FR/GRE/IP */ -}; - -/*! \brief Osmoco NS events */ -enum gprs_ns_evt { - GPRS_NS_EVT_UNIT_DATA, -}; - -struct gprs_nsvc; -/*! \brief Osmocom GPRS callback function type */ -typedef int gprs_ns_cb_t(enum gprs_ns_evt event, struct gprs_nsvc *nsvc, - struct msgb *msg, uint16_t bvci); - -/*! \brief An instance of the NS protocol stack */ -struct gprs_ns_inst { - /*! \brief callback to the user for incoming UNIT DATA IND */ - gprs_ns_cb_t *cb; - - /*! \brief linked lists of all NSVC in this instance */ - struct llist_head gprs_nsvcs; - - /*! \brief a NSVC object that's needed to deal with packets for - * unknown NSVC */ - struct gprs_nsvc *unknown_nsvc; - - uint16_t timeout[NS_TIMERS_COUNT]; - - /*! \brief NS-over-IP specific bits */ - struct { - struct osmo_fd fd; - uint32_t local_ip; - uint16_t local_port; - } nsip; - /*! \brief NS-over-FR-over-GRE-over-IP specific bits */ - struct { - struct osmo_fd fd; - uint32_t local_ip; - unsigned int enabled:1; - } frgre; -}; - -enum nsvc_timer_mode { - /* standard timers */ - NSVC_TIMER_TNS_TEST, - NSVC_TIMER_TNS_ALIVE, - NSVC_TIMER_TNS_RESET, - _NSVC_TIMER_NR, -}; - -/*! \brief Structure representing a single NS-VC */ -struct gprs_nsvc { - /*! \brief list of NS-VCs within NS Instance */ - struct llist_head list; - /*! \brief pointer to NS Instance */ - struct gprs_ns_inst *nsi; - - uint16_t nsei; /*! \brief end-to-end significance */ - uint16_t nsvci; /*! \brief uniquely identifies NS-VC at SGSN */ - - uint32_t state; - uint32_t remote_state; - - struct osmo_timer_list timer; - enum nsvc_timer_mode timer_mode; - int alive_retries; - - unsigned int remote_end_is_sgsn:1; - unsigned int persistent:1; - - struct rate_ctr_group *ctrg; - - /*! \brief which link-layer are we based on?
