Changes to previous submission: - split out the implicit declaration patch (p3 -> p3,p1) - edit libosmocore.pc to include Requires: pkgconfig. (in p3) - add (p5) as an optional commit to completely remove the bundled copy The antisymmetry of osmo_config_list_parse is a matter for a subsequent submission. === The following changes since commit c60de4f35f3f73f3d79b4ff61d0a20b92f818702: build: fix linker error with kasumi_test (2014-10-03 08:48:31 +0200) are available in the git repository at: git://git.inai.de/libosmocore HEAD for you to fetch changes up to a962cd7b62b92a0acc49591d9b3af2b46e023850: build: remove bundled copy of talloc (2014-10-04 11:06:44 +0200) ---------------------------------------------------------------- Jan Engelhardt (5): build: resolve compiler warning about implicit delcaration build: resolve link failure in libosmogsm when --disable-talloc is used build: allow using a system-provided talloc properly build: default to system-provided talloc build: remove bundled copy of talloc Makefile.am | 2 + configure.ac | 9 +- include/Makefile.am | 4 - include/osmocom/core/strrb.h | 2 +- include/osmocom/core/talloc.h | 189 ------------------------------------- include/osmocom/core/utils.h | 2 +- include/osmocom/ctrl/control_cmd.h | 2 +- libosmocore.pc.in | 2 +- src/Makefile.am | 10 +- src/ctrl/control_cmd.c | 2 +- src/ctrl/control_if.c | 2 +- src/gb/common_vty.c | 2 +- src/gb/gprs_bssgp.c | 2 +- src/gb/gprs_bssgp_bss.c | 2 +- src/gb/gprs_bssgp_util.c | 2 +- src/gb/gprs_bssgp_vty.c | 2 +- src/gb/gprs_ns.c | 2 +- src/gb/gprs_ns_frgre.c | 2 +- src/gb/gprs_ns_vty.c | 2 +- src/gsm/Makefile.am | 5 +- src/gsm/ipa.c | 2 +- src/gsm/lapd_core.c | 2 +- src/gsmtap_util.c | 2 +- src/logging.c | 2 +- src/logging_syslog.c | 2 +- src/msgb.c | 2 +- src/msgfile.c | 2 +- src/rate_ctr.c | 2 +- src/signal.c | 2 +- src/statistics.c | 2 +- src/talloc.c | 2 +- src/vty/buffer.c | 2 +- src/vty/command.c | 2 +- src/vty/logging_vty.c | 2 +- src/vty/telnet_interface.c | 2 +- src/vty/utils.c | 2 +- src/vty/vector.c | 2 +- src/vty/vty.c | 2 +- tests/Makefile.am | 12 +-- tests/gb/bssgp_fc_test.c | 2 +- tests/gb/gprs_ns_test.c | 2 +- tests/msgfile/msgfile_test.c | 1 + tests/strrb/strrb_test.c | 2 +- tests/timer/timer_test.c | 2 +- tests/vty/vty_test.c | 2 +- 45 files changed, 53 insertions(+), 253 deletions(-) delete mode 100644 include/osmocom/core/talloc.h

libosmocore: system-talloc+bundled-talloc support
by Jan Engelhardt 03 Oct '14

03 Oct '14

"--disable-talloc" had the effect of a "--enable-system-talloc". So the first patch fixes up all the link failures by adding -ltalloc where needed, _for the case that one decides to use disable-talloc_. Second patch will use pkg-config to determine the parameters for a system talloc. These will be used unconditionally, because the variables TALLOC_CFLAGS/TALLOC_LIBS will be empty when using the bundled talloc. === The following changes since commit c60de4f35f3f73f3d79b4ff61d0a20b92f818702: build: fix linker error with kasumi_test (2014-10-03 08:48:31 +0200) are available in the git repository at: git://git.inai.de/libosmocore HEAD for you to fetch changes up to d6c1607a724a07416c7d39f9b43f7af7349de666: build: default to system-provided talloc (2014-10-03 12:43:25 +0200) ---------------------------------------------------------------- Jan Engelhardt (3): build: resolve link failure in libosmogsm when --disable-talloc is used build: allow using a system-provided talloc properly build: default to system-provided talloc .gitignore | 1 + configure.ac | 26 +++++++++++++++++++------ include/Makefile.am | 5 +++-- include/osmocom/core/talloc.h.in | 6 ++++++ include/osmocom/core/{talloc.h => talloc_int.h} | 0 src/Makefile.am | 7 ++++--- src/gsm/Makefile.am | 5 +++-- tests/Makefile.am | 12 ++++++------ tests/msgfile/msgfile_test.c | 1 + 9 files changed, 44 insertions(+), 19 deletions(-) create mode 100644 include/osmocom/core/talloc.h.in rename include/osmocom/core/{talloc.h => talloc_int.h} (100%)

[PATCH 1/4] gprs: Fix and check BVCI in BSSGP STATUS messages
by Jacob Erlbeck 23 Sep '14

23 Sep '14

Currently the BVCI is not set in all invocations to bssgp_tx_status() when the cause is UNKNOWN_BVCI. This patch adds the argument where it is missing. It also adds a check for compliance (GSM 08.18, 10.4.14.1) to bssgp_tx_status() to emit errors when the following requirement is not fulfilled: The BVCI must be included if (and only if) the cause is either "BVCI blocked" or "BVCI unknown".

Support for integrating RRLP with openbsc
by Kunal Dawn 22 Sep '14

22 Sep '14

Hello everyone I am new to openbsc, and trying to implement my own mobile network for my masters project. Till now everything has gone well and my network is working gud. But the issue is when I am trying to implement rrlp with openbsc. I have set the rrlp mode to ms-based, but there is no response from the phone on sending the request. I have checked that the request is going to the phone with the help of wireshark. So please anyone help me with this, that should i use E-OTD or ms-assisted method for getting the response from the phone. Thanking you in anticipation Kunal

OpenBSC running on an Odroid-XU
by John Baker 18 Sep '14

18 Sep '14

Hi, I have an Odroid-XU I have setup with Debian Wheezy and a USRP B200. After building the UHD drivers from source, I followed the "network from scratch" page. I also configured and built osmo-trx with the --with-neon-vfpv4 option. Things are running OK, a whole lot better than my attempt with OpenBTS actually. I"m able to connect to the network with my Samsung S4 phone, but after an hour or so of the BTS running, I get a UHD recieved time out error (see below). I wonder what could be causing this? I have the B200 plugged into the USB 3.0 port, along with external power. Thanks in advance for any help. root@odroid-wheezy:~# osmo-trx linux; GNU C++ version 4.6.3; Boost_104900; UHD_003.007.002-94-ge56809a0 Config Settings Log Level...............

TIP: Working with nanoBTS behind NAT
by admin＠manateeshome.com 15 Sep '14

15 Sep '14

I wrote a short post about using nanoBTS behind NAT and getting proper connection. http://manatails.net/blog/2014/09/setting-arbitary-destination-ip-for-rtp-p… As OpenBSC does not natively support NAT like Asterisk does, One needs to use a simple hack to manually tell the BSC about the connection information.
