RFC: migrating git.osmocom.org to gitea?

by Harald Welte

Hi all! [please follow-up-to the openbsc(a)lists.osmocom.org mailing list, if there is any discussion, we don't want to drag it over tons of mailing lists in parallel] Some weeks ago, I created https://osmocom.org/issues/5397 but it seems nobody noticed the ticket or had any comments to it. So let me post this as RFC here on the mailing list: In the past, we had a gitolite/gitosis setup, which was fine in the early days of git, but it means that people cannot easily create new repositories, see who has permissions, and we cannot delegate ownership. Even updating SSH keys requires manual interaction of a sysadmin like me. I would therefore suggest to migrate git.osmocom.org to gitea[1] This would allow the following features: * users can self-create any number of personal repositories (like gitlab/github) * we can create 'organizations' along the line of reasonably independent osmocom member projects like op25, who can then manage their own repos/permissions/... * gitea can link to redmine wiki and redmine issue trackers (rather than using its own built-in) For those repositories hosted in gerrit (mainly CNI), we would still keep git.osmocom.org a read-only mirror, like we do it right now. For those repositories not hosted in gerrit, users/projects could then accept merge requests in gitea. Coupling this with 3rd party authentication via github/gitlab/etc should make it easier for the occasional contributor to submit changes. There is a downside, of course; A lot of repo URLs have to change. Most of our current repositories are at git.osmocom.org/project.git while gitea follows a git.osmocom.org/organization/project.git scheme. I'm not sure there is any way to help to mitigate this... Any thoughts, comments?

OSMO HnbGW MGW instance config problem

by Sjur Thomas Lien

Hi Osmocom, I'm setting up osmo-hnbgw and osm-stp ( on centos 8 ) to work with Spidercloud Hnb, and Ericsson MSC/SGSN. Today I had a major breakthrough. I've done my first PS and CS attach, even got voice call up. But it's silent. I see in hnbgw manual that I should configure a co-located MGW instance. I've installed the osmo-mgw, but my problem is the osmo-hnbgw config. There is no option "mgcp" under node hnbgw, so I'm not able to do the config. From my osmo-mgw: OsmoHNBGW(config-hnbgw)# OsmoHNBGW(config-hnbgw)# OsmoHNBGW(config-hnbgw)# list help list [with-flags] show vty-attributes show vty-attributes (application|library|global) write terminal write file [PATH] write memory write show running-config exit end rnc-id <0-65535> log-prefix (hnb-id|umts-cell-id) iuh iucs iups OsmoHNBGW(config-hnbgw)# OsmoHNBGW(config-hnbgw)# OsmoHNBGW(config-hnbgw)# mgcp % Unknown command.

OSMO HnbGW , M3UA problems real MSC and SGSN

by Sjur Thomas Lien

Hi, I've run into problems with M3UA, getting the link up. Our MSC sends a M3UA DAUD message ( Destination Audit ), which is unknown to HnbGw. This might not be a big problem, but the MSC does not support registering of routing-key. And it looks like because MSC rejects the REG-REQ, the HnbGw restarts the signalling link by sending SCTP SHUTDOWN to MSC. I tried to drop the line routing-key in config file, but REG_REQ was sent anyway. I also tried to enter routing-key with context=0, same thing.

Whitelisting/Blocklisting

by Justin

Hi Osmocom, Do we have feature/functionality in OSMO-BSC similar to authorized-regex of OSMO-NITB where a IMSI prefix or regex is used to determine if the subscriber is permitted to register to the network or not. I've tried to looked at the osmo-bsc manual but I haven't seen any configurations related to the said feature/functionality. I've tried also the access-list configuration but I think it's no longer supported in latest version. Regards, Justin

Re: OsmoHNBGW, libosmocore make error , CentOS Linux release 7.9.2009

Hi, please reply to the ML, not only to me. according to [1] osmo-hnbw is available in CentOS_8, but I think you are using CentOS_7. Maybe try using the package from CentOS_8.

OsmoHNBGW, libosmocore make error , CentOS Linux release 7.9.2009

by Sjur Thomas Lien

Hi, Did a git clone of libosmocore. ./configure gives a few faults when checking the log, but seems to finish OK. From config.log: . . . configure:12134: $? = 0 configure:12134: gcc -c -std=gnu11 conftest.c >&5 conftest.c: In function 'main': conftest.c:71:21: error: expected expression before ')' token if (sizeof ((size_t))) ^ configure:12134: $? = 1 configure: failed program was: | /* confdefs.h */ | #define PACKAGE_NAME "libosmocore" | #define PACKAGE_TARNAME "libosmocore" | #define PACKAGE_VERSION "1.6.0.77-381dc" . . . configure:12379: result: -ldl configure:12388: checking for library containing dlsym configure:12419: gcc -o conftest -std=gnu11 conftest.c >&5 /tmp/ccp0wxaN.o: In function `main': conftest.c:(.text+0xa): undefined reference to `dlsym' collect2: error: ld returned 1 exit status configure:12419: $? = 1 configure: failed program was: | /* confdefs.h */ | #define PACKAGE_NAME "libosmocore" | #define PACKAGE_TARNAME "libosmocore" | . . . There are more "conftest.c" errors, but not sure if these are very serious. Anyway, ./configure finishes off without errors when done executing. So next thing is "make". And here I encounter a problem that stops the process: [root@tmaeurcellmngr libosmocore]# make make all-recursive make[1]: Entering directory `/root/hnbgw/osmo-hnbgw/libosmocore' Making all in include make[2]: Entering directory `/root/hnbgw/osmo-hnbgw/libosmocore/include' make all-am make[3]: Entering directory `/root/hnbgw/osmo-hnbgw/libosmocore/include' make[3]: Nothing to be done for `all-am'. make[3]: Leaving directory `/root/hnbgw/osmo-hnbgw/libosmocore/include' make[2]: Leaving directory `/root/hnbgw/osmo-hnbgw/libosmocore/include' Making all in src make[2]: Entering directory `/root/hnbgw/osmo-hnbgw/libosmocore/src' make all-am make[3]: Entering directory `/root/hnbgw/osmo-hnbgw/libosmocore/src' CC context.lo gcc: error: /usr/local/lib:/lib:/usr/lib64: No such file or directory make[3]: *** [context.lo] Error 1 make[3]: Leaving directory `/root/hnbgw/osmo-hnbgw/libosmocore/src' make[2]: *** [all] Error 2 make[2]: Leaving directory `/root/hnbgw/osmo-hnbgw/libosmocore/src' make[1]: *** [all-recursive] Error 1 make[1]: Leaving directory `/root/hnbgw/osmo-hnbgw/libosmocore' make: *** [all] Error 2 [root@tmaeurcellmngr libosmocore]# So this my "real" problem. I did find a compiled version of libosmocore and thought this would help me to compile osmoHNBGW. But , as OsmoHNBGW need a MGW client I ran into another problem. During "make" of osm-mgw: . . CC mgcp_protocol.o In file included from mgcp_protocol.c:39:0: ../../include/osmocom/mgcp/osmux.h:5:33: fatal error: osmocom/netif/osmux.h: No such file or directory #include <osmocom/netif/osmux.h> . . And I saw that "netif" was not there at all. Did a git clone of netif. Then I did a "netif" ./configure. But then I see a new problem, probably caused by the use of the already-compiled libmocore: . . checking netinet/sctp.h usability... yes checking netinet/sctp.h presence... yes checking for netinet/sctp.h... yes checking for osmo_sock_init2_multiaddr in -losmocore... no configure: error: libosmocore built without libsctp support [root@tmaeurcellmngr libosmo-netif]# So , I've hit the wall here.

UCAAT 2022 -- Call for Submissions

by Simon, Matthias (Nokia - DE/Ulm)

Hi, maybe you remember me: I am a TTCN-3 tool developer and fan of your TTCN-3 test suite. :) Therefore I'd like to shamelessly promote a test oriented conference by ETSI, which I think some of you could be interested in. The User Conference on Advanced Automated Testing is calling for submissions, deadline is 2 May 2022. Topics of interest include: * Open-source projects, testing solutions and automated test frameworks. * Lessons learnt from advanced test automation techniques (CI, AI, Cloud, ...) * Good practices for automated testing (TDD, BDD, MBT, ...) * Advances in test specification languages and methodologies * ... See you in Munich maybe? Cheers, Matthias PS: Forgive me, if this mail was inappropriate for this channel.
