Neels Hofmeyr gerrit-no-reply at lists.osmocom.orgReview at https://gerrit.osmocom.org/1139 split subscr_con_allocate()/_free() in bsc_ and msc_ Rename current subscr_con_allocate() and subscr_con_free to bsc_*, and add two separate msc_subscr_con_allocate() and _free(). The msc_subscr_con_free() ignores all lchan members. In libbsc use bsc_*, in libmsc use msc_*. Change-Id: I3cf7c7cafdf4672ec7b26058bba8a77159855257 Future: there will be distinct subscr conns for libbsc and libmsc. --- M openbsc/include/openbsc/gsm_data.h M openbsc/src/libbsc/bsc_api.c M openbsc/src/libmsc/gsm_04_08.c M openbsc/src/libmsc/osmo_msc.c M openbsc/src/osmo-bsc/osmo_bsc_api.c M openbsc/src/osmo-bsc/osmo_bsc_bssap.c M openbsc/src/osmo-bsc/osmo_bsc_sccp.c 7 files changed, 42 insertions(+), 13 deletions(-) git pull ssh://gerrit.osmocom.org:29418/openbsc refs/changes/39/1139/1 diff --git a/openbsc/include/openbsc/gsm_data.h b/openbsc/include/openbsc/gsm_data.h index fc17bfd..6385092 100644 --- a/openbsc/include/openbsc/gsm_data.h +++ b/openbsc/include/openbsc/gsm_data.h @@ -512,8 +512,11 @@ int gsm_btsmodel_set_feature(struct gsm_bts_model *model, enum gsm_bts_features feat);
