2014-08-24gbproxy: Refactor gb_proxy.c into several filesJacob Erlbeck1-0/+39
This patch moves several functions and declarations out of gb_proxy.c to make them reusable by other components and to separate them by context and task. Counter enums (prefix is changed to gbproxy_): enum gbprox_global_ctr -> gprs/gb_proxy.h enum gbprox_peer_ctr -> gprs/gb_proxy.h Generic Gb parsing (prefix is changed to gprs_gb_): struct gbproxy_parse_context -> openbsc/gprs_gb_parse.h gbprox_parse_dtap() -> gprs/gprs_gb_parse.c gbprox_parse_llc() -> gprs/gprs_gb_parse.c gbprox_parse_bssgp() -> gprs/gprs_gb_parse.c gbprox_log_parse_context() -> gprs/gprs_gb_parse.c *_shift(), *_match() -> gprs/gprs_gb_parse.c (no prefix) gbprox_parse_gmm_* -> gprs/gprs_gb_parse.c (static) gbprox_parse_gsm_* -> gprs/gprs_gb_parse.c (static) MI testing/parsing (prefix gprs_ added): is_mi_tmsi() -> gprs/gprs_utils.c is_mi_imsi() -> gprs/gprs_utils.c parse_mi_tmsi() -> gprs/gprs_utils.c TLLI state handling (prefix is changed to gbproxy_): gbprox_*tlli* -> gprs/gb_proxy_tlli.c (except gbprox_patch_tlli, gbproxy_make_sgsn_tlli) Message patching (prefix is changed to gbproxy_): gbprox_*patch* -> gprs/gb_proxy_patch.c gbprox_check_imsi -> gprs/gb_proxy_patch.c Sponsored-by: On-Waves ehf
2014-08-04gprs: Add testcases for the APN string/octet conversion and fix itHolger Hans Peter Freyther1-5/+17
Create a testcase for the gprs_str_to_apn and gprs_apn_to_str routines. While writing the testcase we noticed it is possible to write more bytes than should have been allowed. This is fixed by checking that the max_len is at least 1 (needed to write the first length octet) and to do the size check before writing to the output. Modify the signature of gprs_str_to_apn to put the length/size next to the parameter that requires a size. Done with Jacob
2014-08-04gprs: Create a gprs_utils file and move to be shared code in thereHolger Hans Peter Freyther1-0/+152
We intend to move some of these routines to libosmocore but to avoid a feature symbol clash we are prefixing these routines with gprs_. Done with Jacob
