RFC: CTRL interface and rate_ctr group names
by Harald Welte 06 Oct '17

06 Oct '17

Dear all, this is a post about https://osmocom.org/issues/2362 in which I try to resolve the "naming fuck-up" regarding the automatic export of rate_ctr. In short: * CTRL uses '.' to separate individual elements/nodes of the command * a lot of rate_ctr groups we use so far use '.' in their group names (e.g. 'bssgp.bss_ctx') and counter names (e.g. 'tx.bytes') * This makes the counters un-exportable via CTRL I have a libosmocore patch that verifies the validity of counter names (to not contain spaces or dots) at registration time. This way we can catch any application with erroneous behaviour. However, this causes the following problem: New libosmocore versions will make old apps crash or at least fail to have propre counters, as their names are wrong :( Also, I don't like to replace all '.' in the counter with '_', as in seen in the example of 'bssgp.bss_ctx' there is a semantic difference. 'bssgp.' is denoted to indicate the code module from which the counter is, and 'bss_ctx' denotes the specific object whose counters we refer to. Manually replacing this with 'bssgp_bss_ctx' is ugly. One alternative would be to replace '.' with ':' or '/', which are not characters with a special functoin in the CTRL syntax. This could be even done automatically at counter registration time, simply replace all occurrences of '.' with ':' (and log a warning as a reminder to fix the code?). I prefer that more, but the question is which characters should be reserved for CTRL syntactic purpoess, and which are free to use by the applications to name elements of the CTRL string/node. Any input to this? I personally would go for ':'. As CTRL is very loosely modelled after sysfs, ':' also occurs frequently in sysfs names such as '/sys/bus/usb/devices/1-3:2.0' So we'd keep the '.' as path/node separator, and we use ':' as separator inside counter (and possibly other) names, which is opaque to CTRL. Opinions? Should we further restrict the CTRL interface strings (and those of systems exporting to CTRL) to standard US 7-bit ASCII with a limited set of special characters such as ":-_@" but prevent any non-printable chars or special chars like "{|}()~[]\^`'?<>=;/+*&%$#!"? I would support such a motion. We could even make it more general and use that for all our identifier strings and have a general validation function that all code modules call whenever validating a string identifier used, such as e.g. osmo_fsm names, etc. -- - Harald Welte <laforge(a)gnumonks.org> http://laforge.gnumonks.org/ ============================================================================ "Privacy in residential applications is a desirable marketing option."

disk fill-up of Osmocombuild1, reasons
by Neels Hofmeyr 06 Oct '17

06 Oct '17

I looked at why the 420G of the Osmocombuild1 root fs are full. 1) Slave "build1-debian9-lxc" is running as lxc called 'docker'. /var/lib/lxc/docker/rootfs/var/lib/docker/vfs/dir contains 221G in 333 docker snapshots. It seems to me that these are growing indefinitely, that nothing is removing docker hashes that have been built. Does anyone have a discarding strategy ready that we can deploy there? We need to add one to avoid the build slave filling up again. https://osmocom.org/issues/2539 For now I did docker rmi $(docker images -q -f dangling=true) and rm'd a few stopped containers that had started an openbsc test: docker rm $(docker ps -aq) which removed hundreds of hashes and freed ~110G But half of the 221G are still there, not sure if we need those. I also note that this lxc is not starting automatically after I rebooted Osmocombuild1 (to get rid of some stuck processes). I added lxc.start.auto = 1 to /var/lib/lxc/docker/config Now the server is back up and running, the lxc is started, but the jenkins slave refuses to connect. It tries port 45 but nothing is listening there. I think I've hit this before but can't remember how to solve it :/ https://osmocom.org/issues/2540 2) Slave "Osmocombuild1" is running as user osmocom-build on the host's OS itself. The workspaces make up one large chunk of the disk fill: 94G. Looking at OpenBSC@3, it builds up to 3.8G from the various build matrix workspaces, where each has a compiled libosmocore at >110MB and osmo-iuh at >130MB. Then the parrallel builds each make an own workspace, exploding the total. The good news is that it should cap *somewhere* and not grow indefinitely. We probably should adjust the OpenBSC and various gerrit jobs to clean up the workspace after they are done. We so far never needed the binaries. https://osmocom.org/issues/2538 ~N

build artifact store is quite large
by Neels Hofmeyr 05 Oct '17

05 Oct '17

Hi blobb, I noticed today that our Osmocombuild1's disk is full. It has 420G of space filled up, so it's not exactly the artifact store's fault, but I noticed that it is 3.1 G large, a tad more than I expected. Is the below status expected? Thanks! ~N root@build-1 /home/osmocom-build/jenkins_build_artifact_store # du -hs * 286M OpenBSC-gerrit_IU=--disable-iu,MGCP=--disable-mgcp-transcoding,SMPP=--enable-smpp,label=linux_amd64_debian8 52M

randomness of identifiers
by Harald Welte 05 Oct '17

05 Oct '17

Dear all, Max has been pushing https://gerrit.osmocom.org/#/c/1526 for quite some time, but there was still no conclusion in its review. I guess after more than 8 months in limbo, it's about time we decide how to move ahead with this. In general, we *want* secure/safe identifiers like TMSIs that are not easy to predict by an attacker. Using rand() or some other pseudo-random generator with a predictible seed like the time of the process start is probably not the best choice here. Using the rather strong entropy pool of /dev/urandom or getrandom() is apparently not a good choice either: We can exhaust the entropy pool at whch point we would have to block/wait, which we of course cannot in our architecture. So what do we do? I think we first have to differentiate on the type of randomness needed. Is it a random identifier like TMSI? Is it a random challenge used in cryptographic authentication? Is it random data used for a key? Those require different levels of randomness. For TMSI allocation, my "cryptographic gut feeling"[tm] is that something like rand() or any other pseudo-random generator of significantly large period is sufficient *if* it is seeded by a non-predictable value. So something like seeding with getrandom() result should be fine? For random challenges in authentiation I would probably go for direct use of urandom / getrandom(). If the entropy is exhausted, the quality of the random numbers will get lower, but getrandom() will always return up t 256 bytes. For long-term stable key (Ki/Op) generation for provisioning SIM cards + populating a HLR, I would certainly opt for using stronger randomness sources. However, I don't think we actually implement that anywhere, do we? What do you guys think? Is there somebody on this list more cryptographically qualified to give us proper guidance? If you know somebody skilled who might want to help but is not on this list, would you invite them to join this discussion? -- - Harald Welte <laforge(a)gnumonks.org> http://laforge.gnumonks.org/ ============================================================================ "Privacy in residential applications is a desirable marketing option."

osmo-bts-trx Aborted (core dumped) Error

Hi All, We successfully installed osmo-bsc, osmo-trx, and osmo-bts-trx in Ubuntu 16.04. All osmo elements were successfully run except for osmo-bts-trx. Upon running osmo-bts-trx while the osmo-trx and osmo-bsc is running, “Aborted (core dumped)” error is shown: ((*)) | / \ OsmoBTS <0017> control_if.c:788 CTRL at 127.0.0.1 4238 <0010> telnet_interface.c:102 telnet at 127.0.0.1 4241 <0012> input/ipaccess.c:884 enabling ipaccess BTS mode, OML connecting to 192.168.1.41:3002 <000b> trx_if.c:589 Open transceiver for phy0.0 <0012> input/ipa.c:129 connection done. <0012> input/ipaccess.c:705 received ID get <0001> oml.c:223 O&M Get Attributes [0], Manufacturer Dependent State is unsupported by TRX. <0001> oml.c:223 O&M Get Attributes [0], Manufacturer Dependent State is unsupported by TRX.

IPA multiplex code in libosmo-abis? where to move gsup_client and oap_client?
by Neels Hofmeyr 05 Oct '17

05 Oct '17

Comments are welcome for https://osmocom.org/issues/2534 I want to remove gsup_client code dup and need a place to put it. Can't go to libosmocore, because it uses libosmo-abis' IPA Multiplex. My main open question is: libosmo-abis sounds like it is specifically for the A-bis interface. But GSUP, which we use to talk to the OsmoHLR, is not at all related to A-bis. Does it make sense to put it in libosmo-netif? Or move the IPA Multiplex to libosmocore? And hence remove some duplication between libosmo-abis and libosmo-netif? What do you guys think is worth the trouble? Just move gsup to libosmo-abis.git and care later? Thanks! ~N

what is bumpversion used for?
by Neels Hofmeyr 04 Oct '17

04 Oct '17

Hi Max, I asked before and now we have https://gerrit.osmocom.org/4127 so let me ask again: What is bumpversion used for in your 'make release' setup? I would expect version bumping to be a human choice. How is it intended to work? ~N

osmo-bsc integration to osmo-msc
by Ron 04 Oct '17

04 Oct '17

Hi All, Is there a link on how to integration osmo-bsc to osmo-msc? or osmo-bsc_nat is required to integrate osmo-bsc to osmo-msc? A config file for both osmo-bsc and osmo-msc that can be shared will be greatly appreciated. TIA. Best Regard, Ron Menez ron.menez(a)entropysolution.com<mailto:ron.menez@entropysolution.com>

git repository delays
by Neels Hofmeyr 02 Oct '17

02 Oct '17

Hi all, for a while now I notice that it can take really long to just do a 'git fetch' of few kilobytes volume (or none at all) on a couple of repositories. I would expect a rapid trickle through all, most to be finished within half a second, but sometimes it takes three full minutes to bump 21 git repositories. These are all from the gerrit ssh URL. Does anyone know what causes this delay? Would it be gerrit processing time, server load or network congestion? I haven't taken a closer look yet... ~N
