RFC: unit tests for kernel GTP module
by Harald Welte 31 Dec '25

31 Dec '25

Dear GTP-interested folks, I would love to somehow get towards some degree of unit testing (or even "continuous integration") for teh kernel GTP code. We currently have the original code in the kernel, we had some recent small fixes and now are getting more patches into place. With relatively few active users out there (and probably none of them in production yet), it's particularly easy to introduce regressions while working on the code. Also, having tested new code even against a test set with limited covrage could help to get more confidence in new patches and thus get them merged sooner. Using tools like sgsnemu of OpenGGSN and the command line tools included in libgtpnl, it should be possibel to cook up some scripts for testing. Even the most basic set of tests would be an improvement over what we have now. One could also think about pcap replay to test with hand-crafted or real-world packets from other GTP implementations. As much as I'd like to put something like this into place myself, I don't think I will be able to work much on this in the near future. The GTP module at this point is a pure hobby and contrary to some years ago while I started it, I don't have any contract work in the GTP area at this point, so other projects currently unfortunately get more attention. So in case somebody among the GTP-interested parties (Travelping, OAI, ...) would want to do something in terms of testing, I'd be more than happy if somebody would step ahead. Otherwise it's all just vapourware going to end up on my ever-growing TODO list :/ Also, if netdev folks have some ideas/pointers about possible frameworks/tools for this kind of testing [it must exist for at least some other kernel networking code?]: Please let me know. I'd be interested to have a look if there's something that can be used as a basis (starting network namespaces, sending/transmitting packets, test case startup/teardown, ...) My "old school" approach would have been to start one or multiple user-mode-linux kernels (those that are to be tested), and then have scripts that set up a gtp socket and gtp tunnels via the libgtp command line tools, and throw packets at that. But I'm sure there must be quite powerful frameworks for that kind of testing in the 21st century? How do other tunneling implementations handle this?

Data Rate of EGPRS is Too Low
by XINKE ZHANG 28 Jun '18

28 Jun '18

Hi all, I have set up the EGPRS network using software bundles (osmo-nitb + osmo-bts-trx + osmo-trx + osmo-pcu + osmo-sgsn + openggsn) based on the USRP B210 platform. Now the cell phone can connect to the EGPRS network, but the network is not stable and the data rate is too low (only about 8kbs). Is this data rate correct? If not, could you pls send me some working config files? Thank you. Best Regards, Xinke

GPRS doesn't work
by weng alexa 25 Jun '18

25 Jun '18

Hi all, I set up the EGPRS network using software bundles (osmo-bts-trx + osmo-trx + osmo-pcu + osmo-sgsn + osmo-ggsn + osmo-bsc + osmo-msc + osmo-hlr) based on the USRP B210 platform. Now the cell phone can connect to the EGPRS network, but the phone has no IP address. All the config files are in the attachments, could you help we find what's wrong? Thanks sincerely All of the osmo-pcu's log is like the below: 20180625043250233 DRLCMACMEAS <0007> gprs_rlcmac_meas.cpp:183 DL Bandwitdh of IMSI=xxxxxxxxxxxxxxxx/ TLLI=0xb6ccf813: 190 KBits/s

osmo-pcu build failures on Debian 8.0
by Harald Welte 06 Jun '18

06 Jun '18

For quite some time, osmo-pcu has been causing build failures on Debian 8. You can find a build log e.g. at https://build.opensuse.org/package/live_build_log/network:osmocom:nightly/o… The visible sign is that for some reasson there are additional log lines present in the output of our unit tests, like: [ 127s] TBF(TFI=0 TLLI=0xffeeddcc DIR=DL STATE=FLOW EGPRS) downlink acknowledge [ 127s] TBF(TFI=0 TLLI=0xffeeddcc DIR=DL STATE=FLOW EGPRS) Final ACK received. [ 127s] +DL packet loss of IMSI= / TLLI=0xffeeddcc: 0% [ 127s] TBF(TFI=0 TLLI=0xffeeddcc DIR=DL STATE=FLOW EGPRS) changes state from FLOW to WAIT RELEASE [ 127s] TBF(TFI=0 TLLI=0xffeeddcc DIR=DL STATE=WAIT RELEASE EGPRS) starting timer T3193 [release (DL-TBF)] with 0 sec. 0 microsec, cur_fn=0 where the "+" is the unexpected additional line. Does anyone have any information about why that is? I don't see any related changes recently. -- - Harald Welte <laforge(a)gnumonks.org> http://laforge.gnumonks.org/ ============================================================================ "Privacy in residential applications is a desirable marketing option."
