RFC: speed up gerrit verifications by using dependency artifacts
by André Boddenberg 01 Apr '17

01 Apr '17

Hi, some weeks a go the topic about using dependency-artifacts to speed up gerrit verifications was mentioned by Neels in the "RFC: jenkins pipeline" thread [1]. I was curious and wrote a bash script (osmo-artifacts.sh) [2], which enables build jobs to archive and fetch dependencies. Instead of Docker it simply uses archives to store them. An artifact's name has the following form: ( n(${project}.${branch}.${shortRev}_) ).tar.gz Openbsc builds are 50 % faster when using artifacts. [3] The jenkins.sh [2] script had to be slightly modified i.e. basically split into two functions: 1) buildProjectDeps() 2) buildProject() A third function to generate the artifact name has been added. The template.sh [2] script illustrates this description. What do you think about the result/artifactStore/approach in general? A cleanUpArtifactStore.sh script running as a cron job is already on my mind, but imo it's a good point to discuss the intermediate result. blobb [1] http://lists.osmocom.org/pipermail/openbsc/2017-March/010400.html [2] git clone https://github.com/blobbsen/diy-artifacts.git [3] https://jenkins.blobb.me/job/openBSC_multi-configuration_withArtifacts_test…

commit python script to openbsc/contrib
by Keith Whyte 31 Mar '17

31 Mar '17

Hi all. I have a python script I'd like to commit to openbsc/contrib. It reads the SMS table, gives stats and retrieves individual messages. - should maybe go in openbsc/contrib/sms ? Anyway, should I submit this via gerrit + code review or is there another way? There's really no point in having jenkins look at it, right? Thanks! k.

[PATCH 0/2] fixes for pysim
by Philipp Maier 28 Mar '17

28 Mar '17

Hello, I would like to propose the two changes for pysim, the first is for fixing the sysmo-usim-sjs1 support and the second fixes the missing support for writing the ICCID to a sysmo-usim-sjs1. If there are no major concerns with that I would like to merge the two patches to master.

Updates on Osmocom Conference 2017
by Harald Welte 28 Mar '17

28 Mar '17

OsmoCon 2017 updates There are some updates related to OsmoCon2017, the first Osmocom Conference, held on April 21st, 2017 in Berlin, Germany. See http://osmocom.org/news/68 for the web version of this announcement. == Summary == Summary (for those too busy to read the full post): * Schedule of talks has been released http://osmocom.org/projects/osmo-dev-con/wiki/OsmoCon2017#Schedule * Travel Grants available for participants who are otherwise unable to travel to Berlin: http://osmocom.org/projects/osmo-dev-con/wiki/OsmoCon2017_TravelGrants * Social Event details available, including menu: http://osmocom.org/projects/osmo-dev-con/wiki/OsmoCon2017_SocialEvent * April 21st is approaching fast, make sure you get your Ticket in time. Limited number of seats available http://shop.sysmocom.de/products/ticket-for-osmocon-2017 == Details == === Schedule has been released === The list of talks with their abstracts has been on the website for quite some time, but now we actually have put together a schedule based on those talks. Please see http://osmocom.org/projects/osmo-dev-con/wiki/OsmoCon2017#Schedule for the schedule. As you can see, the day is fully packed with talks about Osmocom cellular infrastructure projects. We had to cut some talk slots short (30min instead of 45min), but I'm confident that it is good to cover a wider range of topics, while at the same time avoiding fragmenting the audience with multiple tracks. === Travel Grants === We are happy to announce that we have received donations to permit for providing travel grants! This means that any attendee who is otherwise not able to cover their travel to OsmoCon 2017 (e.g. because their interest in Osmocom is not related to their work, or because their employer doesn't pay the travel expenses) can now apply for such a travel grant. For more details see http://osmocom.org/projects/osmo-dev-con/wiki/OsmoCon2017_TravelGrants and/or constact osmocon2017(a)sysmocom.de. === Social Event === Tech Talks are nice and fine, but what many people enjoy even more at conferences is the informal networking combined with good food. For this, we have the social event at night, which is open to all attendees. See more details about it at http://osmocom.org/projects/osmo-dev-con/wiki/OsmoCon2017_SocialEvent -- - Harald Welte <laforge(a)gnumonks.org> http://laforge.gnumonks.org/ ============================================================================ "Privacy in residential applications is a desirable marketing option."

gerrit openid login: osmocom.org vs. projects.osmocom.org
by Neels Hofmeyr 27 Mar '17

27 Mar '17

Has someone made osmocom.org login redirect to projects.osmocom.org? Because since recently I observe this: I go to osmocom.org, click on "Sign in". It *redirects* me to projects.osmocom.org/login. I log in. I go to gerrit, enter, as always https://osmocom.org/openid I get another login screen, this time on osmocom.org without 'projects.' Interesting, there seem to be two realms, maybe from cookie rules. Ok then, I add projects to the openid, for gerrit login: https://projects.osmocom.org/openid and it works, nice. However, now I seem to be logged in as a kind of ghost of my user. I'm logged in as 'nhofmeyr(a)sysmocom.de', but no patches are on my page and I don't have the voting nor admin permissions I normally have. When instead of clicking on "Sign in" on osmocom.org redmine, I *manually* enter https://osmocom.org/login (omitting projects.), I can login on osmocom.org and my gerrit user works out. I notice that with projects.osmocom.org I am user ID 1000073, while with osmocom.org I am 1000005. In the gerrit user database, I see distinct user IDs: ▶ ssh go 'gerrit gsql -c "select * from account_external_ids where account_id = 1000073 or account_id = 1000005"' ACCOUNT_ID | EMAIL_ADDRESS | EXTERNAL_ID -----------+-----------------------+-------------------------------------------- 1000005 | nhofmeyr(a)sysmocom.de | https://osmocom.org/openid/user/91 1000005 | NULL | username:neels 1000073 | nhofmeyr(a)sysmocom.de | https://projects.osmocom.org/openid/user/91 When I manually patch up the 1000073 to 1000005 in the last row, both openid URLs work out to the correct user. So gerrit potentially gets confused by one and the same user, fails to match the email addresses rather than the openid provider. Looking at the other registered users, most use the osmocom.org and not projects.osmocom.org, so you all may be susceptible to the same issue. I also see that four have entered http:// as openid, without SSL, which seems to me is something we should rather not allow. For example, laforge's user is shadowed in the same way just because of the non-https: 1000004 | laforge(a)gnumonks.org | https://osmocom.org/openid/user/7 1000021 | laforge(a)gnumonks.org | http://osmocom.org/openid/user/7 If redirecting to projects.o.o is intentional and the way to go (TM), I should probably pre-empt problems for existing users by creating external ids with 'projects' in the openid url, pointing at the proper existing users. Otherwise we should avoid magical forwarding of osmocom.org logins to projects.osmocom.org. ~N

GSM Audio Problems and
by Edwin Reed-Sanchez 26 Mar '17

26 Mar '17

Dear Osmocom list We are getting several audio problems and dropped calls. The audio sounds like static. We are also getting large frame correction in the logs, and SACCH deactivation timeout. Any ideas what could be the likely culprit? 2017-03-24_14:30:57.93546 <001a> rtp_proxy.c:295 Correcting frame difference of 74518293571 frames 2017-03-24_14:31:11.45899 <001a> rtp_proxy.c:295 Correcting frame difference of 1 frames 2017-03-24_14:31:11.51590 <001a> rtp_proxy.c:295 Correcting frame difference of 2 frames 2017-03-24_14:31:11.65513 <001a> rtp_proxy.c:295 Correcting frame difference of 1 frames 2017-03-24_14:32:08.95028 <0004> abis_rsl.c:1343 (bts=1,trx=0,ts=1,ss=0) SACCH deactivation timeout. 2017-03-24_14:37:10.11844 <0004> abis_rsl.c:662 (bts=1,trx=0,ts=1,ss=0) is back in operation.

python on FreeBSD in libosmocore
by Thorsten Alteholz 24 Mar '17

24 Mar '17

Hi, as python2 will disappear sooner or later, I tried to replace all python2 references in libosmocore by the generic "python" [1]. Unfortunately the build fails on FreeBSD[2]. Google didn't want to explain me why there might be /usr/bin/python2 but no /usr/bin/python, so do you have any idea what is wrong here?

runtime cpu-detection for osmo-trx
by Philipp Maier 24 Mar '17

24 Mar '17

Dear list members, dear Mr. Tsou, we had a couple of problems with the SSE support in Transceiver52 of osmo-trx. The problem was that the -march=native, that is used when compiling the x86 code in Transceiver52M/x86/. This would create a platform dependent binary that can not be easily moved to another platform. (e.g. binary is compiled on a machine that does support SSE4.1, but used on a machine that only supports SSE3) In order to solve the problem, we have added logic to detect the CPU type at runtime and to switch between the base implementation (Transceiver52M/common) and between the platform specific implementation. Since there might be different compilers out there, which do not support the -msse3 and -msse4.1 options, we also modified the build system to detect if the compiler supports -msse3 and -msse4.1. If no support can be detected, there is a hard fallback to the generic implementation. The patches are currently in the review process, you can find them below: https://gerrit.osmocom.org/2098 buildenv: Turn off native architecture builds https://gerrit.osmocom.org/2099 cosmetic: Make parameter lists uniform https://gerrit.osmocom.org/2100 ssedetect: Add runtime CPU detection https://gerrit.osmocom.org/2101 cosmetic: Add info about SSE support https://gerrit.osmocom.org/2102 buildenv: Make build CPU invariant https://gerrit.osmocom.org/2103 cosmetic: remove code duplication https://gerrit.osmocom.org/2104 Add test program to verify convolution implementation https://gerrit.osmocom.org/2134 buildenv: Split up SSE3 and SSE4.1 code There is also a readmine ticket concerning this change: https://osmocom.org/issues/1869 It would be very kind if you could have a look at the changes and, if possible, to approve them. regards, Philipp Maier -- Philipp Maier <pmaier(a)sysmocom.de> http://www.sysmocom.de/ ======================================================================= * sysmocom - systems for mobile communications GmbH * Alt-Moabit 93 * 10559 Berlin, Germany * Sitz / Registered office: Berlin, HRB 134158 B * Geschaeftsfuehrer / Managing Director: Harald Welte
