[PATCH 0/4] core/conv: Fast Viterbi decoding

by Thomas Tsou

Hi all, This patch set adds to libosmocore an optimized Viterbi decodeer for architecture specific (Intel SSE) and non-specific cases. The implementation covers codes with constraint lengths of K=5 and K=7 and rates 1/4 to 3/4, which make up the majority of GSM use cases. Speedup from the current implementation is in the range of 5 to 20 depending on the processor and code type. API is unchanged. Tested on Haswell (i7-4770K) and Atom (D2550). Additional test codes from osmo-bts are included. Further tests for AWGN bit-error-rate and benchmarks can be found in the following repository. https://github.com/ttsou/osmo-conv-test Here are some examples. Bit error test for GPRS CS2 with SNR of 5 dB and 100000 bursts. $ ./conv_test -c 2 -e -r 5 -i 100000 ================================================= [+] Testing: GPRS CS2 [.] Specs: (N=2, K=5, non-recursive, flushed, not punctured) [.] Input length : ret = 290 exp = 290 -> OK [.] Output length : ret = 588 exp = 588 -> OK [.] BER tests: [..] Testing base: [..] Input BER.......................... 0.042443 [..] Output BER......................... 0.000006 [..] Output FER......................... 0.001350 (135) [..] Testing SIMD: [..] Input BER.......................... 0.042460 [..] Output BER......................... 0.000005 [..] Output FER......................... 0.001240 (124) Timed AFS benchmark with 8 threads and 100000 bursts per thread. $ ./conv_test -b -c 10 -j 8 -i 100000 ================================================= [+] Testing: GSM TCH/AFS 6.7 [.] Specs: (N=4, K=5, recursive, flushed, punctured) [.] Input length : ret = 140 exp = 140 -> OK [.] Output length : ret = 448 exp = 448 -> OK [.] Performance benchmark: [..] Encoding / Decoding 800000 bursts on 8 thread(s): [..] Testing base: [..] Elapsed time....................... 4.320001 secs [..] Rate............................... 25.925920 Mbps [..] Testing SIMD: [..] Elapsed time....................... 0.458272 secs [..] Rate............................... 244.396341 Mbps [..] Speedup............................ 9.426718 -TT

Final review of L1SAP ported to current maste

by Harald Welte

Dear all, the valuable L1SAP abstraction has been sitting out of master for too long time. It is a pity that this has taken so long. I've finally been able to put some time into osmo-bts again and reviewed the following patch series. It consists of mostly Andreas' work, interspersed with smaller patches/fixups that I introduced after the respective original patch from Andreas. I have started a sysmobts between all of the major steps in this patch series and did a short manual tests involving registration (LU) of two MS, mobile-to-mobile call and vty-to-mobile SMS. So far I couldn't see any problems. What has not been tested yet is the PCU interface as well as encryption support. I plan to do this later this week. I intend to merge the code after this current review cycle. Please take your time to have a look and provide feedback (if any), so we can get this over and work on new features again, rather than infrastrutural changes. I didn't yet rebase the osmo-bts-trx interface on top of the L1SAP, as I don't have a hardware setup for it, and I will leave it to the owners of such hardware to publish/push the respective code after L1SAP is merged.

libosmocore/libosmo-abis changes + fallout

by Harald Welte

In preparation of the libctrl move to libosmocore[*], I had to move some IPA related functionality from libosmo-abis to libosmocore. This is required as libctrl needs IPA functions, but we cannot make a cyclic library (build) dependency between libosmocore and libosmo-abis. I took the decision to rename some of the sysmbols for consistency. This is always ugly and creates fall-out, so there never is a good time for it. I thought now it makes sense as things are undergoing modifications anyway. I was able to do 'make check / make distcheck' of libosmocore / libosmo-abis / osmo-pcu / osmo-bts and openbsc master branches with the recent commits. If I missed something, please let me know by private mail and I'm happy o clean up further. Regards, Harald [*] required to add a control interface to osmo-bts, which is required for things like managing/triggering clock recalibration on sysmobts from external programs. -- - Harald Welte <laforge(a)gnumonks.org> http://laforge.gnumonks.org/ ============================================================================ "Privacy in residential applications is a desirable marketing option."

Moving libctrl to libosmocore

by Harald Welte

Hi Daniel, I am currently working on moving the control interface to libosmocore, you can find the status in the 'laforge/libctrl' branch. The reason behind this is that I will be adding a control interface to osmo-bts soon. The first dozens of commits is basically a filtered list of commits from the openbsc repository. The last few commits are towards making it build outside libosmocore. Most of the commits are pretty simple and uninteresting. However, there is one change that I would like to ask you to review: adf2530fc3c9d45dd1d528cd6d92d462702e3f19 where I'm trying to avoid using the openbsc-global 'tall_bsc_ctx' and introduce a more hierarchical inheritance of allocations. As this is the first time I've looked at the control interface, I might have made some wrong decisions there. The remaining steps are: * remove 'struct gsm_network' as reference and replace with a 'void * data' or 'void *priv' field * possibly rename/prefix the function names, so we end up with osmoctrl_* for the symbol names.

[PATCH] gbproxy: Add gbprox_clear_patch_filter() (Coverity)

by Jacob Erlbeck

Add a separate function to clear the IMSI filter to be used instead of gbprox_set_patch_filter(cfg, NULL, ...). Albeit it fixes a Coverity issue (Unchecked return value), it is a false positive, since the return value is always 0 in these cases. Nevertheless it is more obvious what happens when an explicit clear function is called. Using NULL as filter argument of gbprox_set_patch_filter still clears the filter.

Re: [PATCH] sysmobts: Deal with ciphering when we have a transport clash

by Harald Welte

Hi Holger, the patches look fine to me, although it hurts that such a hack and layering violations is actually needed. I'm wondering if the spec designers didn't come up with a more elegant method. In OpenBSC we could of course disable early classmark sending, but we cannot exclude osmo-bts / sysmobts from being used with other implementations either. What about OpenBSC waiting for the classmark change to arrive _if_ early classmark sending is enabled? At least, if A5/4 is ever used, this is the only way to support it anyway, as A5/4 is indicated only in CM3, and CM3 is only part of CLASSMARK CHANGE, but not part of the CM SERVICE REQUEST or PAGING RESPONSE. However, as we are probably all quite sure that the GSM industry is not capable of rolling out a 'new' cipher in less than 10 years, I'm not sure if we should worry about this here. -- - Harald Welte <laforge(a)gnumonks.org> http://laforge.gnumonks.org/ ============================================================================ "Privacy in residential applications is a desirable marketing option."

OsmoSGSN [PATCH], Network Service

by Michal Grznár

Hi, I am using OsmoSGSN in topology with OpenGGSN and proprietary simulator of BSS. There was a problem with an implementation of Network service, cause Network Service implementation in the simulator of BSS is based on different release of 3GPP standard (3GPP TS 48. 016 v7. 4. 0 (2008-04)/Network service (Release 7))...and the problem is that in IP-subnetwork, which I am using there is no use for RESET or UNBLOCK procedure, so I had to do a PATCH in gprs_ns.c, which was needed to complete succesful connection between sim-bss and OsmoSGSN: switch (nsh->pdu_type) { case NS_PDUT_ALIVE: +++ LOGP(DNS, LOGL_INFO, "Rx NS ALIVE\n"); +++ /*mark NS-VC as alive*/ +++ (*nsvc)->state = NSE_S_ALIVE; +++ (*nsvc)->remote_state = NSE_S_ALIVE; +++ /*initiate TEST procedure: Send ALIVE_ACK and start timer*/ +++ rc = gprs_ns_tx_simple((*nsvc), NS_PDUT_ALIVE_ACK); +++ nsvc_start_timer((*nsvc), NSVC_TIMER_TNS_TEST); +++ break; . . . } another PATCH I needed to do was to change a little bit procedure for allocation of P-TMSI in procedure uint32_t sgsn_alloc_ptmsi(void) in gprs_sgsn.c uint32_t sgsn_alloc_ptmsi(void) { struct sgsn_mm_ctx *mm; uint32_t ptmsi; restart: +++ ptmsi = rand() | 0xc0000000; /*because of GPRS IMSI ATTACH*/ llist_for_each_entry(mm, &sgsn_mm_ctxts, list) { if (mm->p_tmsi == ptmsi) goto restart; } return ptmsi; } because in GPRS IMSI ATTACH in message ATTACH COMPLETE (3GPP 24.008, 23.003, 48.018) there is new TLLI==new allocated P-TMSI and I need local TLLI, so I had to do it this way regards Michal
