From 8254cf75bf818e715201c670c7fb81b9a23dec0b Mon Sep 17 00:00:00 2001 From: Harald Welte Date: Mon, 29 May 2017 13:42:19 +0200 Subject: libbsc: Create pcu-socket only as specified in config file Since commit b4999b60d48bcbb5aa575973d068e07ab672e095 we created PCU sockets at hard-coded paths in the filesystem by default for all BTSs. This is inflexible and prevents the use of multiple BSC instances on a single filesystem, or the placement of the sockets in a more secure location than /tmp. The new approach with this patch is that * no PCU sockets are created by default * only for those BTSs where a 'pcu-socket' is configured via VTY, the socket will actually be created Change-Id: Ie9079470584777dcc31f85f9bf0808f479156ccb Closes: OS#2293 --- openbsc/src/libbsc/bsc_init.c | 14 -------------- openbsc/src/libbsc/bsc_vty.c | 26 ++++++++++++++++++++++++++ 2 files changed, 26 insertions(+), 14 deletions(-) (limited to 'openbsc/src') diff --git a/openbsc/src/libbsc/bsc_init.c b/openbsc/src/libbsc/bsc_init.c index 520b2e24e..caec8005d 100644 --- a/openbsc/src/libbsc/bsc_init.c +++ b/openbsc/src/libbsc/bsc_init.c @@ -507,8 +507,6 @@ int bsc_network_configure(const char *config_file) { struct gsm_bts *bts; int rc; - char pcu_sock_path[PATH_MAX]; - char pcu_sock_path_ending[PATH_MAX]; rc = vty_read_config_file(config_file, NULL); if (rc < 0) { @@ -536,18 +534,6 @@ int bsc_network_configure(const char *config_file) LOGP(DNM, LOGL_FATAL, "Error enabling E1 input driver\n"); return rc; } - - strcpy(pcu_sock_path, PCU_SOCK_DEFAULT); - sprintf(pcu_sock_path_ending,"_%i", bts->nr); - if (bts->nr > 0) - strcat(pcu_sock_path, pcu_sock_path_ending); - rc = pcu_sock_init(pcu_sock_path, bts); - - if (rc < 0) { - LOGP(DNM, LOGL_FATAL, - "PCU L1 socket failed for bts %i\n", bts->nr); - return rc; - } } return 0; diff --git a/openbsc/src/libbsc/bsc_vty.c b/openbsc/src/libbsc/bsc_vty.c index f14a20568..f17bde604 100644 --- a/openbsc/src/libbsc/bsc_vty.c +++ b/openbsc/src/libbsc/bsc_vty.c @@ -53,6 +53,7 @@ #include #include #include +#include #include @@ -280,6 +281,8 @@ static void bts_dump_vty(struct vty *vty, struct gsm_bts *bts) vty_out(vty, "Early Classmark Sending: %s%s", bts->early_classmark_allowed ?
