Good Afternoon, last week at the sysmocom office Daniel and me continued to work on the window handling. We have now a proper abstraction that allows us to unit test the DL and UL window handling. The encode/decode of the RBB is now compatible to itself. While doing our manual tests (sending a big enough ICMP echo request) we noticed that in the alloc algorithm b case the we get a lot of NACKs. In the same setup (only alloc algorithm is changed) the A algorithm has no NACKs. I am now going to re-write the allocation handling. In terms of operation on the first DL assignment (through the PCH) we can only use a singleslot but when re-using the TBF we might go for multislot. In case the of UL handling we could always try to use multislot assignments. Is this understanding correct? holger -- - Holger Freyther <hfreyther(a)sysmocom.de> http://www.sysmocom.de/ ======================================================================= * sysmocom - systems for mobile communications GmbH * Schivelbeiner Str. 5 * 10439 Berlin, Germany * Sitz / Registered office: Berlin, HRB 134158 B * Geschaeftsfuehrer / Managing Directors: Holger Freyther, Harald Welte

Current list of failures in the pcu

by Holger Hans Peter Freyther

Good Morning, we at sysmocom continued to add structure/architecture to the PCU code and started to systematically test the code (using something as simple as ICMP ping/reply) Observations: * "alloc algorithm b" has little (3kbit/s) more bandwidth than just using the single slot assignment with CS4. There are also some open coverity issues about this multi slot code. * Congestion is badly handled. When using a ping that creates IP fragments the LLC queue of the TBF gets so long that we expire half the IP fragments before sending them. This means the MS at the downlink never receives all the IP fragments of a PING. We played with the BSVC-FLOW-CONTROL parameters but they don't have any influence here. We have added counting of queue size and calculation of the average queue delay to the LLC class. One option is to drop packages based on the PDU lifetime and the current queue delay. $ sudo ping -s 1800 -i 0.1 10.23.42.6 (CS4, alloc-algorithm a) is enough to re-produce this issue. * RLC V(Q) V(R) handling. It appears that after and before the refactoring the Received Block Bitmap (RBB) is wrongly encoded. The encode and decode are not compatible to each other (thanks to the architecture sysmocom is adding to the code this can now be unit tested!). So as soon as we don't receive a frame from the UL. The send window at the phone and the PCU is going out of sync. After making changes to the window we have also witnesses that on a fully received window V(Q) and V(R) were WindowSize away from each other. <0005> tbf.cpp:1579 UL DATA TFI=0 received (V(Q)=55 .. V(R)=60) <0005> tbf.cpp:1624 - BSN 60 storing in window (55..118) <0005> rlc.cpp:173 - Raising V(R) to 61 <0005> tbf.cpp:1690 - Scheduling Ack/Nack, because 20 frames received. <0005> encoding.cpp:374 Encoding Ack/Nack for TBF(TFI=0 TLLI=0xfa45049d DIR=UL) (final=0) SSN=61 <0005> encoding.cpp:408 - V(N): "RRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRR" R=Received N=Not-Received This part might be something we broke but we will try to re-produce with a unit test. We will continue to work on unit-testing the RLC window handling if anyone outside sysmocom interested in getting a more stable PCU? holger -- - Holger Freyther <hfreyther(a)sysmocom.de> http://www.sysmocom.de/ ======================================================================= * sysmocom - systems for mobile communications GmbH * Schivelbeiner Str. 5 * 10439 Berlin, Germany * Sitz / Registered office: Berlin, HRB 134158 B * Geschaeftsfuehrer / Managing Directors: Holger Freyther, Harald Welte

Summary of osmo-pcu failures/defects

by Holger Hans Peter Freyther

Hi, I have added rate counters to the PCU and noticed that a lot of frames in the DL are re-sent without there actually being any NACK or transmission errors. I have also re-produced a "stall" by just using ping with a big enough data size and a low enough interval (the PCU appears to transmit the ICMP PING but the MS never gets to send a PONG packet). In both cases it could be a scheduling issue (e.g. we don't schedule the UL Packet ACK/NACK). Is any of you aware of it? I had already highlighted that the scheduling is not fair. I wonder if we are seeing starvation (and will re-factor to be able to unit test this). In terms of scheduling. For the SBA we are already having a reservation that we try to honor in multiple places. Maybe it is time to extend it and have more reservations? holger -- - Holger Freyther <hfreyther(a)sysmocom.de> http://www.sysmocom.de/ ======================================================================= * sysmocom - systems for mobile communications GmbH * Schivelbeiner Str. 5 * 10439 Berlin, Germany * Sitz / Registered office: Berlin, HRB 134158 B * Geschaeftsfuehrer / Managing Directors: Holger Freyther, Harald Welte

gprs_rlcmac_received_lost() in gprs_rlcmac_meas.cpp

by Daniel Willmann

Hello Andreas, while looking through the osmo-pcu code to figure out why some connections stall we had some problems making sense of the elapsed time calculations in gprs_rlcmac_meas.cpp. Could you confirm/deny my assumptions about it or explain the idea behind it? > gettimeofday(&now_tv, NULL); > elapsed = ((now_tv.tv_sec - loss_tv->tv_sec) << 7) > + ((now_tv.tv_usec - loss_tv->tv_usec) << 7) / 1000000; I assume here you're calculating the duration of the measurement period so far and since you want to have sub-second accuracy you multiply everything with 128. Why 128? Is it becasue it simplifies the throughput calculation? (tbf->meas.dl_bw_octets/elapsed in gprs_rlcmac_dl_bw()) > if (elapsed < 128) > return 0; Is the intention here that the duration of the measurements is supposed to be one second? So every second these measurements are printed out and reset?

Dropping LLC frames due the TBF destruction

by Holger Hans Peter Freyther

Hi, my clean-ups are not done but there is a basic structure now that can be refined. I started to add statistics to the BTS (and then will add statistics per tbf but they are short lived so one would need to be quick to see them). E.g. in tbf_free we are freeing still pending llc_frames and I assume that these are related to the "Killing pending DL TBF" and others. I am wondering why: * there is no indication to the SGSN for dropped frames/octets? * can't the DL-TBF be re-associated/updated after the assignment is done again? holger -- - Holger Freyther <hfreyther(a)sysmocom.de> http://www.sysmocom.de/ ======================================================================= * sysmocom - systems for mobile communications GmbH * Schivelbeiner Str. 5 * 10439 Berlin, Germany * Sitz / Registered office: Berlin, HRB 134158 B * Geschaeftsfuehrer / Managing Directors: Holger Freyther, Harald Welte

Losing ACKs due TLLI changes?

by Holger Hans Peter Freyther

Hi, I got this log from the pcu while using my E71 (the only sub in this network). <0007> gprs_rlcmac_meas.cpp:103 UL RSSI of TLLI=0x88661bc6: -67 dBm <0002> bts.cpp:945 Got ACK, but UL TBF is gone TLLI=0xe512eba3 <0007> gprs_rlcmac_meas.cpp:158 DL packet loss of IMSI=274080000004765 / TLLI=0xe512eba3: 0% <0002> tbf.cpp:668 TBF TFI=0 TLLI=0x88661bc6 T3169 timeout during transsmission <0002> tbf.cpp:690 - Assignment was on PACCH <0002> tbf.cpp:694 - No uplink data received yet So there is an ACK for TLLI=0xe512eba3 but at the same time the tlli 0x88661bc6 is timing out. PCU->SGSN TLLI=0x88661bc6 Attach Request SGSN->PCU TLLI=0x88661bc6 Attach Accept (new P-TMSI) PCU->SGSN TLLI=0xe512eba3 Attach Complete (new TLLI) (6s later) Now the question is how the PCU should behave. I think the MS is allowed to change the TLLI (after a P-TMSI assignment) after the contention resolution is completed. From my reading there is no content resolution on the UL. My E71 appears to run into a timeout and then issue a RACH request to send the Attach Complete. I think I have seen other equipment failing to transmit the Attach Complete at all. I think for the SGSN -> PCU side we should generally look things up by IMSI (there is already a warning in the code), for the MS->PCU side. I think we should store the old and new TLLI (and then put new_tlli into tlli once the new one is being used). comments? holger -- - Holger Freyther <hfreyther(a)sysmocom.de> http://www.sysmocom.de/ ======================================================================= * sysmocom - systems for mobile communications GmbH * Schivelbeiner Str. 5 * 10439 Berlin, Germany * Sitz / Registered office: Berlin, HRB 134158 B * Geschaeftsfuehrer / Managing Directors: Holger Freyther, Harald Welte

Fwd: Losing ACKs due TLLI changes?

by Vladimir Rolbin

Hi, I don't see any print connected to the Uplink TBF request for "Attach accept" (by MS). At this moment the TLLI has been already updated but UL TBF still does not exist (what bts->tbf_by_tlli(m_tlli, GPRS_RLCMAC_UL_TBF) returns?). Corresponding to TS 04.60, 11.2.29 Packet Uplink Assignment possibly may use DL TFI to address the MS in place of TLLI (we still don't know if it's accepted or not by MS). Also the uplink FN may be used to find corresponding UL TBF context (according to Packet Uplink Assignment RRBP field) for UL Packet Control Ack which contains relevant TLLI. So is it really necessary to link UL and DL TBFs in the case? ...

Status on re-factorings

by Holger Hans Peter Freyther

Hi all, I have continued with my refactorings and mostly done: * Remove global state (e.g. the global lists for ta, sba, tbf, bts * Add back-pointers to tbf, trx, pdch which will allow to kill methods that take trx, ts as parameters. * Started to use C++ classes and functions. * Stop poking of internals from other classes areas (gprs_rlcmac_data is still in front of me and the most hairy part). I will probably need to spend another 40h on this code to finally have structure in it. Once this is done I will add counters and rate counters, improve the VTY inspection... and then I can search for the actual defects we are experiencing. While doing the refactorings I noticed that both pcu_l1_if.cpp and sysmo_sock.cpp have different ways to reset the BTS/PCU state. Both of them have different issues and are both incomplete. It is the perfect example where structure would have saved timed and made the code more reliable at the same time. I am going to work on gprs_rlcmac_data.cpp and while my refactorings so far where low risk.. the risk will increase when touching and structuring the above, e.g. it is hard to judge if the difference in the code-clones is on purpose or actually a bug. There will be only one way to find it out though. I am afraid that I have 52 commits compares to master and I am only half way done. Review and changing directions will be quite difficult at this point in time. holger -- - Holger Freyther <hfreyther(a)sysmocom.de> http://www.sysmocom.de/ ======================================================================= * sysmocom - systems for mobile communications GmbH * Schivelbeiner Str. 5 * 10439 Berlin, Germany * Sitz / Registered office: Berlin, HRB 134158 B * Geschaeftsfuehrer / Managing Directors: Holger Freyther, Harald Welte

Fairness of sched_poll

by Holger Hans Peter Freyther

Good Morning, sched_poll is doing: llist_for_each_entry(tbf, &gprs_rlcmac_ul_tbfs, list) { /* this trx, this ts */ if (tbf->trx_no != trx || tbf->control_ts != ts) continue; /* polling for next uplink block */ if (tbf->poll_state == GPRS_RLCMAC_POLL_SCHED && tbf->poll_fn == poll_fn) *poll_tbf = tbf; if (tbf->ul_ack_state == GPRS_RLCMAC_UL_ACK_SEND_ACK) *ul_ack_tbf = tbf; if (tbf->dl_ass_state == GPRS_RLCMAC_DL_ASS_SEND_ASS) *dl_ass_tbf = tbf; if (tbf->ul_ass_state == GPRS_RLCMAC_UL_ASS_SEND_ASS) *ul_ass_tbf = tbf; } llist_for_each_entry(tbf, &gprs_rlcmac_dl_tbfs, list) { /* this trx, this ts */ if (tbf->trx_no != trx || tbf->control_ts != ts) continue; /* polling for next uplink block */ if (tbf->poll_state == GPRS_RLCMAC_POLL_SCHED && tbf->poll_fn == poll_fn) *poll_tbf = tbf; if (tbf->dl_ass_state == GPRS_RLCMAC_DL_ASS_SEND_ASS) *dl_ass_tbf = tbf; if (tbf->ul_ass_state == GPRS_RLCMAC_UL_ASS_SEND_ASS) *ul_ass_tbf = tbf; } New tbf's will be added to the front (llist_add). Is it on purpose that the dl_tbfs are preferred over ul_tbfs and that the last of each tbf's will be found? What is the reasoning for this? What will collect/catch poll_fn's that are in the past? holger -- - Holger Freyther <hfreyther(a)sysmocom.de> http://www.sysmocom.de/ ======================================================================= * sysmocom - systems for mobile communications GmbH * Schivelbeiner Str. 5 * 10439 Berlin, Germany * Sitz / Registered office: Berlin, HRB 134158 B * Geschaeftsfuehrer / Managing Directors: Holger Freyther, Harald Welte

TBF differences for Uplink and Downlink

by Holger Hans Peter Freyther

Hi, in my refactorings (creating a TBF class and moving code that modifes the internals into the TBF) I am trying to make gprs_rlcmac_ul_tbfs and gprs_rlcmac_dl_tbfs private and I notice code like: if (dir == GPRS_RLCMAC_UL_TBF) { llist_for_each_entry(tbf, &gprs_rlcmac_ul_tbfs, list) { if (tbf->state_is_not(GPRS_RLCMAC_RELEASING) && tbf->tlli == tlli && tbf->tlli_valid) return tbf; } } else { llist_for_each_entry(tbf, &gprs_rlcmac_dl_tbfs, list) { if (tbf->state_is_not(GPRS_RLCMAC_RELEASING) && tbf->tlli == tlli) return tbf; } } llist_for_each_entry(tbf, &gprs_rlcmac_ul_tbfs, list) { if (tbf->state_is_not(GPRS_RLCMAC_RELEASING) && tbf->poll_state == GPRS_RLCMAC_POLL_SCHED && tbf->poll_fn == fn && tbf->trx_no == trx && tbf->control_ts == ts) return tbf; } llist_for_each_entry(tbf, &gprs_rlcmac_dl_tbfs, list) { if (tbf->state_is_not(GPRS_RLCMAC_RELEASING) && tbf->poll_state == GPRS_RLCMAC_POLL_SCHED && tbf->poll_fn == fn && tbf->trx_no == trx && tbf->control_ts == ts) return tbf; } In the first code. Why is tlli_valid only checked for the UL TBF and not the downlink one? holger -- - Holger Freyther <hfreyther(a)sysmocom.de> http://www.sysmocom.de/ ======================================================================= * sysmocom - systems for mobile communications GmbH * Schivelbeiner Str. 5 * 10439 Berlin, Germany * Sitz / Registered office: Berlin, HRB 134158 B * Geschaeftsfuehrer / Managing Directors: Holger Freyther, Harald Welte

Question regarding TS allocation algorithm(s)

by Holger Hans Peter Freyther

Hi, after the report about the missing usf assignment I started to refactor the allocation algorithms (remove code duplication, apply information hiding, directly access things). Looking at the code it appears that algorithm A and B will always select the first (in case of A) or the first and following (in case of B) enabled PDCH. I have the suspicion that in case of algorithm A only the first PDCH will be used to assign to phones? And in case of algorithm B it is likely that the assignments are not spread equally across the available timeslots? can someone confirm/deny? holger -- - Holger Freyther <hfreyther(a)sysmocom.de> http://www.sysmocom.de/ ======================================================================= * sysmocom - systems for mobile communications GmbH * Schivelbeiner Str. 5 * 10439 Berlin, Germany * Sitz / Registered office: Berlin, HRB 134158 B * Geschaeftsfuehrer / Managing Directors: Holger Freyther, Harald Welte

[PATCH 1/8] tbf: Begin to add some structure to the tbf code

by Holger Freyther

From: Holger Hans Peter Freyther <holger(a)moiji-mobile.com> The TBF should use the IMSI to identify a block flow but all handling is spread across the entire code. Start to clean this up by moving relevant code into the tbf file. Afterwards one can clean up and add more internal structure. --- src/Makefile.am | 6 +- src/gprs_bssgp_pcu.cpp | 121 +------------------------------------ src/tbf.cpp | 160 +++++++++++++++++++++++++++++++++++++++++++++++++ src/tbf.h | 27 +++++++++ 4 files changed, 194 insertions(+), 120 deletions(-) create mode 100644 src/tbf.cpp create mode 100644 src/tbf.h diff --git a/src/Makefile.am b/src/Makefile.am index 38a4b3c..6646f53 100644 --- a/src/Makefile.am +++ b/src/Makefile.am @@ -40,7 +40,8 @@ libgprs_la_SOURCES = \ gsm_timer.cpp \ bitvector.cpp \ pcu_l1_if.cpp \ - pcu_vty.c + pcu_vty.c \ + tbf.cpp if ENABLE_SYSMOBTS libgprs_la_SOURCES += \ @@ -72,7 +73,8 @@ noinst_HEADERS = \ bitvector.h \ pcu_vty.h \ sysmo_l1_if.h \ - femtobts.h + femtobts.h \ + tbf.h osmo_pcu_SOURCES = pcu_main.cpp diff --git a/src/gprs_bssgp_pcu.cpp b/src/gprs_bssgp_pcu.cpp index 4833af8..3432bca 100644 --- a/src/gprs_bssgp_pcu.cpp +++ b/src/gprs_bssgp_pcu.cpp @@ -21,6 +21,7 @@ #include <gprs_rlcmac.h> #include <gprs_bssgp_pcu.h> #include <pcu_l1_if.h> +#include <tbf.h> static struct gprs_bssgp_pcu the_pcu = { 0, };

by Vladimir Rolbin

Hi all, It looks like usf found (allocated) is never used. I guess something like tbf->dir.ul.usf[ts] = usf is missed. Regards, Vladimir Rolbin.

TBF and API design.. (boolean/int trap)

by Holger Hans Peter Freyther

Good Evening, I started a branch to add a basic structure to the TBF handling. The reasons why I am doing this is for another lengthy email. I just came across a piece of code and would like to create some awareness: int write_immediate_assignment(bitvec * dest, uint8_t downlink, uint8_t ra, uint32_t ref_fn, uint8_t ta, uint16_t arfcn, uint8_t ts, uint8_t tsc, uint8_t tfi, uint8_t usf, uint32_t tlli, uint8_t polling, uint32_t fn, uint8_t single_block, uint8_t alpha, uint8_t gamma, int8_t ta_idx); and invocations like: if (sb) plen = write_immediate_assignment(immediate_assignment, 0, ra, Fn, qta >> 2, bts->trx[trx].arfcn, ts, bts->trx[trx].pdch[ts].tsc, 0, 0, 0, 0, sb_fn, 1, bts->alpha, bts->gamma, -1); else plen = write_immediate_assignment(immediate_assignment, 0, ra, Fn, tbf->ta, tbf->arfcn, tbf->first_ts, tbf->tsc, tbf->tfi, tbf->dir.ul.usf[tbf->first_ts], 0, 0, 0, 0, bts->alpha, bts->gamma, -1); With the above method and two invocations it is difficult to get all arguments right and it is a strong argument against ever writing code like this. With C++ one could create overloads that take the bts and tbf as parameters. Or if one really only wants to have a single method use a struct to pass the parameters. This has the benefit of naming the parameters and will certainly require the same amount of stack space as the current option. So please, don't write methods like the above as they make maintaining the code more difficult than it needs to be. holger -- - Holger Freyther <hfreyther(a)sysmocom.de> http://www.sysmocom.de/ ======================================================================= * sysmocom - systems for mobile communications GmbH * Schivelbeiner Str. 5 * 10439 Berlin, Germany * Sitz / Registered office: Berlin, HRB 134158 B * Geschaeftsfuehrer / Managing Directors: Holger Freyther, Harald Welte

C++ for the PCU

by Holger Hans Peter Freyther

Dear Ivan, all, I started to do work on the PCU and didn't compile C++ for a long time. I was surprised how long it takes to compile the code. From my point of view we are taking the hit of g++ without really using any of the features that C++ vould provide (e.g. no stack variables with automatic cleanup..).

Weird usage of gprs_ns_vty_init from gprs_bssgp_create

by Holger Hans Peter Freyther

Dear Andreas, Ivan, when trying to understand the CPU usage of the PCU without having any subscribers I noticed the following backtrace: #0 _int_malloc (av=0x402fe4d4, bytes=52) at malloc.c:3241 #1 0x4023a3b8 in __GI___libc_malloc (bytes=52) at malloc.c:2859 #2 0x4929b6e8 in _talloc_zero () from /usr/lib/libosmocore.so.4 #3 0x49422e44 in vector_init () from /usr/lib/libosmovty.so.0 #4 0x4941f1f8 in install_element () from /usr/lib/libosmovty.so.0 #5 0x492e602c in gprs_ns_vty_init () from /usr/lib/libosmogb.so.2 #6 0x0001b670 in gprs_bssgp_create (local_port=<optimized out>, sgsn_ip=184194049, sgsn_port=<optimized out>, nsei=<optimized out>, nsvci=2, bvci=2, mcc=<optimized out>, mnc=<optimized out>, lac=1, rac=0, cell_id=0) at gprs_bssgp_pcu.cpp:585 #7 0x00016990 in pcu_rx_info_ind (info_ind=0x7) at pcu_l1_if.cpp:431 #8 pcu_rx (msg_type=<optimized out>, pcu_prim=0x3) at pcu_l1_if.cpp:577 #9 0x00017914 in pcu_sock_read (bfd=0x6a3f0) at sysmo_sock.cpp:151 #10 pcu_sock_cb (bfd=0x6a3f0, flags=1) at sysmo_sock.cpp:218 #11 0x49294ff4 in osmo_select_main () from /usr/lib/libosmocore.so.4 #12 0x0000a668 in main (argc=<optimized out>, argv=0xbee40b04) at pcu_main.cpp:219 This means when a info indication is received gprs_bssgp_create will be called which will re-initialize the VTY commands but more important re-set vty_nsi inside the VTY code of libosmogb. But it also means that vty_nsi will be a dangling pointer in case of 1.) gprs_ns_nsip_connect, btsctx_alloc, gprs_ns_nsip_listen fail 2.) Between the sysmobts software exiting and re-starting and bringing OML back up 3.) More cases that I might not understand. The dangling pointer will lead to a crash when the VTY of the PCU is used in such situation/window. does any of you care to fix that race? I think the easiest would be to just close/open/bind/listen/connect on the NS once we get a new config. holger -- - Holger Freyther <hfreyther(a)sysmocom.de> http://www.sysmocom.de/ ======================================================================= * sysmocom - systems for mobile communications GmbH * Schivelbeiner Str. 5 * 10439 Berlin, Germany * Sitz / Registered office: Berlin, HRB 134158 B * Geschaeftsfuehrer / Managing Directors: Holger Freyther, Harald Welte

hi ivan, there is still one patch left in my jolly/meas branch that has not been mergen: commit 890ae7e4fcf7d74c238ed2ce0e3f090f1af492c2 and the fixup: commit 784f9004ba3576ede57dada63876451f32d2d852 it keeps the timing advance from a TBF and uses it for new TBFs, so the mobile can be at any distance. this was tested up to 4 km (with sysmobts). if it is ok, i will combine these patches and push the result to master. regards, andreas

problems with dissecting

by jolly

hi, steve and me experienced a problem with dissecting a "packet resource request" at pcu. the patch i attached will show the following output: $ make && src/osmo-pcu PayloadType = 1 | spare = 0 | R = 0 | MESSAGE_TYPE = 5 | Exist_ACCESS_TYPE = 1 | ACCESS_TYPE = 3 | : ID | Choice PacketResourceRequestID = 1 | u.TLLI = 0x7ee0e8fd | : End ID | Exist_MS_Radio_Access_capability = 1 | : MS_Radio_Access_capability | MS_RA_capability_value { | Choice MS_RA_capability_value_Choice = 1 | u.Content length = 34 | RF_Power_Capability = 4 | Exist_A5_bits = 1 | A5_bits = 96 | ES_IND = 1 | PS = 0 | VGCS = 0 | VBS = 0 | Exist_Multislot_capability = 1 | : Multislot_capability | Exist_HSCSD_multislot_class = 0 | Exist_GPRS_multislot_class = 1 | GPRS_multislot_class = 10 .... this is all correct, but then i patched the get_ms_class_by_capability() function at grps_rlcmac_data.c: ... printf("we have = %d\n", cap->Count_MS_RA_capability_value); for (i = 0; i < cap->Count_MS_RA_capability_value; i++) { printf("index=%d\n", cap->MS_RA_capability_value[i].IndexOfAccTech); printf("exists multislot capability %d\n", cap->MS_RA_capability_value[i].u.Content.Exist_Multislot_capability); printf("exists class %d\n", cap->MS_RA_capability_value[i].u.Content.Multislot_capability.Exist_GPRS_multislot_class); printf("class %d\n", cap->MS_RA_capability_value[i].u.Content.Multislot_capability.GPRS_multislot_class); ... the output continues as this: we have = 2 index=2 exists multislot capability 0 exists class 1 class 10 index=0 exists multislot capability 0 exists class 0 class 0 the "class 10" is correct, also it is correct that the class only exists in the first entry of the capability array. the output of the dissector states that multislot capability exists (Exist_Multislot_capability = 1), but if i look at the structure, this field is not set. i looked at the dissector code, but don't really understand why CSN_NEXT_EXIST works for some elements and not for others. any ideas? regards, andreas

[ANNOUNCE] OsmoDevCon 2013-04-04 till 2013-04-07, Berlin

by Harald Welte

Dear fellow Osmcoom developers, it is my pleasure to finally announce the date + venue of OsmoDevCon 2013: Date: April 04 through April 07, 2013 Place: IN-Berlin, Lehrter Str. 53, Berlin Like last year, this is an event for developers of the various Osmocom proejects. Reservation and confirmation of reservation is required. The event is free of charge. The Room is made available by IN-Berlin e.V., an Internet related non-profit organization. Lunch catering will be sponsored (so far by sysmocom GmbH, but if any other sponsors come up, we are happy to share the cost). So all you have to cover is your own travel + accomodation costs, as well as breakfast and dinner. If you are an active developer and cannot afford travel/accomodation, please let me know and I'll see if we can do something about it. If you would like to attend, please send a message to laforge(a)gnumonks.org applying for registration of the event. The registration deadline is March 5, i.e. one week from now. There is no detailed schedule of talks yet. I will start a separate discussion suggesting / collecting topics in the next couple of days. More information is (and will be made) available at http://openbsc.osmocom.org/trac/wiki/OsmoDevCon2013 Further discussion regarding the event should be directed at the osmocom-event-orga(a)lists.osmocom.org mailing list, to avoid cross-posting over the various project-specific lists.

Invalid decoding of some PACKET_RESOURCE_REQUESTs

by Steve Markgraf

Hi, I noticed a bug in the dissector, which seems to happen when then Exist_A5_bits field is set to 0, and results in the following fields (Exist_Multislot_capability/Exist_GPRS_multislot_class) being decoded incorrectly. Thus, get_ms_class_by_capability() is returning NULL instead of the GPRS_multislot_class, which is interestingly dissected correctly. This is one of the messages where this happens: 4017dfb83a3f628a7045500898f28109100297e0080b2b If I add it to the RLCMACTest it fails, so I propose it should be added ;) My quite recent version of Wireshark (1.8.2) is decoding this message fine, see the attachment. I've gone through the recent changes on packet-gsm_rlcmac.c and packet-csn1.c in Wireshark, but couldn't spot the commit that fixed it so far. Regards, Steve

Idea for synchonous logging/review of debug + GSMTAP

by Harald Welte

Hi all, one of the problems when debugging PCU issues is: How to take proper logs on-site where a problem shows up and give them back to the developer(s) for analysis. If you capture the PCU stdout or configure file-based logging, you will have a hard time corellating that with PCAP traces taken on the RLC/MAC side and/or on the Gb side. Therefore I propose a new idea here and would like to get your review: What about implementing a "GSMTAP" log target for libosmocore? This way we could encapsulate the log messages into a special GSMTAP message, which would be sent synchronously in the GSMTAP stream together with RLC/MAC messages on the lower end. The same could in fact be utilized in osmo-bts, too. This way we could capture BTS log/debug output in-order to L1 messages that we receive and transmit. What do you think about it? I would be willing to draft the GSMTAP sub-header format and write + submit the wireshark dissector, if somebody wants to write libosmocore log target. Ideally we would log _all_ messages to that target, and include the subsystem and log level in a header field, so the log verbosity could still be adjusted at the point of review, instead only at the time of logging.

Default build is broken since the 17th of January

by Holger Hans Peter Freyther

Hi, the default build is broken since the 17th of october. Anynone feels responsible to fix it after the merge? Build results can be seen here[1]. It probably has to with enabling sysmobts support but not direct PDCH queue access. holger [1] http://jenkins.osmocom.org/jenkins/job/osmo-pcu/label=linux_i386_debian_squ…

lack of progress in PCU patch merging / git (ab)use

by Harald Welte

Dear all, it is a pity to see that since many weeks there has been no progress on merging any of Andreas' work. I think everyone involved is to be blamed to some extent. Andreas because the provided branches are not kept clean, Ivan probably for lack of time, and me for not paying more attention and helping this process along. The general life-cycle in any project, including osmo-pcu, should be as follows: * contributor starts on some improvements, creates private branch * master advances meanwhile * contributor rebases (not merges!) his changes on top of more recent master * contributor indicates that his branch is ready for merge * maintainer merges (some of?) the commits of the contributor branch * contributor re-bases remaining commits on new master * contributor requests merge of remaing patches ... If I open 'gitk' on any of the branches (master / jolly / jolly_dsp) I get grey hair (to say the least). One would normally expect: 1) 'jolly' to be based on some (maybe not current) master 2) 'jolly_dsp' to be based on 'jolly' Neither of the two is the case. I've tried to * rebase jolly on top of master as well as * rebase jolly_dsp on top of jolly and both are impossible due to the series of merges and the unclear ancestry / relationship of the branches. Or, just for fun, try 'git diff origin/jolly..origin/jolly_dsp. It shows you anything else but what one would expect Andreas: Please take some time to clean up the mess. Your 'jolly' branch should contain a series of clean per-feature commit's on top of current master, and 'jolly_dsp' should be a set of few patches on top of 'jolly'. This way there is always a clean queue of changesets that Ivan can merge (or cherry-pick). I can understand that if I was in Ivan's place, I would not really know where to even start merging some of those contributions. Thanks for everyone's attention. Please take some time to get this resolved. Let me know if you have some questions. There are plenty of people with lots of git experience around (Holger, Pablo, myself) who can help if something is unclear.

Suspected memory leak in PCU

by Harald Welte

Hi all, while running osmo-pcu, it appears that it is leaking memory. At startup time it consumes 4188 kBytes of virtual memory (on sysmobts-v2), while after about 8MBytes of data transfer of a single GPRS-MS over 48 hours, the virtual size has expanded to 8584 kBytes. Now I know that VSS is not RSS, etc. - but the fact that it always only increasees, and increases with traffic is a clear indication of some leakage somewehere. Unfortunately it also seems talloc is not used correctly in osmo-pcu, as a USR1 signal doesn't really show any allocated objects beyond two. So somehow either not all allocations are done with talloc, or the allocation hierarchy does not link the objects to the root talloc context.

Hi Ivan. More pcu logs (Nokia 5000d-2).

bug in wireshark decoder of osmo-pcu

by jolly

hi, i get wrong decoding of RLCMAC control block. the decoder of osmo-pcu is decoding following sequence: 0x40,0x16,0x76,0x67,0x74,0x02,0x26,0x64,0xe8,0x65,0x64,0x69,0x00,0x3e,0x4c,0x00,0x2b,0x2b,0x2b,0x2b,0x2b,0x2b,0x2 this is the result: PayloadType = 1 | spare = 0 | R = 0 | MESSAGE_TYPE = 5 | Exist_ACCESS_TYPE = 1 | ACCESS_TYPE = 0 | : ID | Choice PacketResourceRequestID = 1 | u.TLLI = 0xd99dd008 | : End ID | Exist_MS_Radio_Access_capability = 1 | : MS_Radio_Access_capability | MS_RA_capability_value[0] { | Choice MS_RA_capability_value_Choice = 3 | u.Content length = 25 ... at this point, the length of the content is 25 bits: | RF_Power_Capability = 1 | Exist_A5_bits = 1 | A5_bits = 80 | ES_IND = 1 | PS = 1 | VGCS = 0 | VBS = 0 | Exist_Multislot_capability = 1 | : Multislot_capability | Exist_HSCSD_multislot_class = 0 | Exist_GPRS_multislot_class = 1 | GPRS_multislot_class = 12 | GPRS_Extended_Dynamic_Allocation_Capability = 1 | Exist_SM = 0 ... at this point all 25 bits are decoded, so the decoder must abort decoding of content of Multislot_capability_t (see gsm_rlcmac.cpp). instead, it continues with the data found after these 25 bits: (all crap from now on) | Exist_ECSD_multislot_class = 0 | Exist_EGPRS_multislot_class = 0 | Exist_DTM_GPRS_multislot_class = 1 | DTM_GPRS_multislot_class = 2 | Single_Slot_DTM = 1 | : DTM_EGPRS_Params | Exist_DTM_EGPRS_multislot_class = 0 | : End DTM_EGPRS_Params | : End Multislot_capability | Exist_Eight_PSK_Power_Capability = 0 | COMPACT_Interference_Measurement_Capability = 1 | Revision_Level_Indicator = 0 | UMTS_FDD_Radio_Access_Technology_Capability = 0 | UMTS_384_TDD_Radio_Access_Technology_Capability = 0 | CDMA2000_Radio_Access_Technology_Capability = 0 | UMTS_128_TDD_Radio_Access_Technology_Capability = 0 | GERAN_Feature_Package_1 = 0 | Exist_Extended_DTM_multislot_class = 0 | Modulation_based_multislot_class_support = 0 | Exist_HighMultislotCapability = 0 | Exist_GERAN_lu_ModeCapability = 0 | GMSK_MultislotPowerProfile = 3 | EightPSK_MultislotProfile = 3 | MultipleTBF_Capability = 1 | DownlinkAdvancedReceiverPerformance = 0 | ExtendedRLC_MAC_ControlMessageSegmentionsCapability = 1 | DTM_EnhancementsCapability = 0 | Exist_DTM_GPRS_HighMultislotClass = 0 | PS_HandoverCapability = 1 | MS_RA_capability_value[0] } | MS_RA_capability_value[0] { | Choice MS_RA_capability_value_Choice = 0 | u.Content length = 0 | RF_Power_Capability = 2 | Exist_A5_bits = 1 | A5_bits = 50 | ES_IND = 1 | PS = 0 | VGCS = 1 | VBS = 1 | Exist_Multislot_capability = 0 | Exist_Eight_PSK_Power_Capability = 0 | COMPACT_Interference_Measurement_Capability = 1 | Revision_Level_Indicator = 0 | UMTS_FDD_Radio_Access_Technology_Capability = 1 | UMTS_384_TDD_Radio_Access_Technology_Capability = 0 | CDMA2000_Radio_Access_Technology_Capability = 1 | UMTS_128_TDD_Radio_Access_Technology_Capability = 1 | GERAN_Feature_Package_1 = 0 | Exist_Extended_DTM_multislot_class = 0 | Modulation_based_multislot_class_support = 1 | Exist_HighMultislotCapability = 0 | Exist_GERAN_lu_ModeCapability = 1 | GERAN_lu_ModeCapability = 6 | GMSK_MultislotPowerProfile = 1 | EightPSK_MultislotProfile = 1 | MultipleTBF_Capability = 0 | DownlinkAdvancedReceiverPerformance = 3 | ExtendedRLC_MAC_ControlMessageSegmentionsCapability = 0 | DTM_EnhancementsCapability = 0 | Exist_DTM_GPRS_HighMultislotClass = 1 | DTM_GPRS_HighMultislotClass = 2 | : DTM_EGPRS_HighMultislotClass | Exist_DTM_EGPRS_HighMultislotClass = 1 | : End DTM_EGPRS_HighMultislotClass | : End MS_Radio_Access_capability | there are two problems with the decoder: - it does not check if the length has been exceeded while decoding Multislot_capability_t content. if the length is lower than all elements in Multislot_capabilit_t, the decoder must abort decoding the content. this is no bug. (the definition used at that point should be M_NEXT_EXIST_OR_NULL instead of M_NEXT_EXIST, see gsm_rlcmac.cpp) - even if the correct definition is used, the csn1 decoder will not use the length given at "u.Content length" to abort. instead it checks for reaching total length of coded data. i played a bit with the code, but could not fix it without breaking other things. but decoding with wireshark works. would it be possible to port latest wireshark code? regards, andreas

hi, just experiences some problems with my jolly branch (osmo-pcu): commit e6228b34a75efcb6b0700ac29672d62539860fbf Author: Andreas Eversberg <jolly(a)eversberg.eu> Date: Tue Jul 3 13:36:03 2012 +0200 TBF acknowledged mode finished for both link directions commit c7e7f6868b6f24346424dee904f4e76d3f216ff4 Author: Ivan Kluchnikov <kluchnikovi(a)gmail.com> Date: Fri Jun 29 22:53:15 2012 +0400 Implemented Paging procedure on CCCH. Added functions: - gprs_bssgp_pcu_rx_paging_ps() for handling paging message from BSSGP; - write_paging_request() for writing paging request message; - gprs_rlcmac_paging_request() and pcu_l1if_tx_pch() for sending paging request message to BTS. the lower commit adds paging procedure, but if i diff between these commits, i see that my upper commit removes the paging procedure. but i don't see it, if i "git show e6228b...". any ideas? regards, andreas

Multislot finished and well tested

by jolly

hi, i like to announce that multislot supports has been finished and is working well. it supports all classes, but i could not test other classes than semi-duplex class 12. the algorithm allocates as many downlink slots as allowed by class and as avaiable. it will only allocate a single uplink slot. there is no dynamic dl/up allocation depending on traffic. the code is located at osmo-pcu: jolly branch: git log 4b470ffe regards, andreas

talloc, malloc and memory leaks

by Holger Hans Peter Freyther

Hi, this is not meant as an intensive review on memory allocations in the PCU code. While browsing the code of the ready-to-send method to select the next payload I noticed the code below: RlcMacDownlink_t * mac_control_block = (RlcMacDownlink_t *)malloc(sizeof(RlcMacDownlink_t)); LOGP(DRLCMAC, LOGL_DEBUG, "+++++++++++++++++++++++++ TX : Packet Paging Request +++++++++++++++++++++++++\n"); decode_gsm_rlcmac_downlink(pag_vec, mac_control_block); LOGPC(DCSN1, LOGL_NOTICE, "\n"); LOGP(DRLCMAC, LOGL_DEBUG, "------------------------- TX : Packet Paging Request -------------------------\n"); bitvec_free(pag_vec); This and other all other places really should use talloc to make finding memory leaks more easy (e.g. by printing the leak report), the second part is that we appear to leak this on every paging message sent by the PCU and the third is actually a question. Should we use a GCC extension that helps dealing with local variables? GCC can call a cleanup function on exit of the scope, an example can be seen here[1] nad this[2] is the description of the feature. holger [1] https://mail.gnome.org/archives/gtk-devel-list/2011-November/msg00050.html [2] http://gcc.gnu.org/onlinedocs/gcc/Variable-Attributes.html#Variable-Attribu… -- - Holger Freyther <hfreyther(a)sysmocom.de> http://www.sysmocom.de/ ======================================================================= * sysmocom - systems for mobile communications GmbH * Schivelbeiner Str. 5 * 10439 Berlin, Germany * Sitz / Registered office: Berlin, HRB 134158 B * Geschaeftsfuehrer / Managing Directors: Holger Freyther, Harald Welte

Compiling with clang --analyze

by Holger Hans Peter Freyther

Hi, one more email for tonight. Using clang/smatch from time to time can highlight certain issues. The easiest way to invoke it is this: $ make CC="clang --analyze" CXX="clang++ --analyze" 1.) gprs_bssgp_pcu.cpp:241:6: warning: Access to field 'state' results in a dereference of a null pointer (loaded from variable 'bctx') if (bctx->state & BVC_S_BLOCKED && pdu_type != BSSGP_PDUT_STATUS) ^~~~ the handling of bctx is a bit weird, in theory it can be NULL but I am not sure if we are likely to receive the messages that would make the PCU crash though. gprs_bssgp_pcu_rcvmsg can call the above function/line with a NULL bctx. 2.) gprs_rlcmac.cpp:728:25: warning: Assigned value is garbage or undefined tbf->dir.ul.usf[ts] = usf[ts]; ^ ~~~~~~~ Probably true, alloc_algorithm_b is really too big to be readable to verify that this is not a false positive. cheers holger -- - Holger Freyther <hfreyther(a)sysmocom.de> http://www.sysmocom.de/ ======================================================================= * sysmocom - systems for mobile communications GmbH * Schivelbeiner Str. 5 * 10439 Berlin, Germany * Sitz / Registered office: Berlin, HRB 134158 B * Geschaeftsfuehrer / Managing Directors: Holger Freyther, Harald Welte

Re: Multislot finished and well tested

by Andreas Eversberg

Holger Hans Peter Freyther wrote: > in the above it is possible that !poll_tbf and usf == 0x7, is this the > right behavior in case no TBF could be found? hi holger, if poll_tbf is set, we must use an unassigned usf, because only the polled mobile may transmit. (usf 7 is never assigned.) if poll_tbf is not set and if no uplink ressource is required, i use usf 7 (any other usf would also be ok, since we don't need any mobile to transmit on uplink, but i use 7, because it is never assigend to any mobile). regards, andreas

git tree / branches / ancestor?

by Harald Welte

Hi all! while reviewing the current PCU code in the git repository, it occurred to me that somehow the jolly_new branch doesn't seem to be based on master, and the only common ancestor is 9b06ff0c4c49f1927b9029d38e16670a7b7301fb from June 15. In fact, Ivan seems to have made a number of changes concurrently with Andreas, but not basing on each other's code. It's really a big mess, from what I can tell. I'm referring to the followign commit's by Ivan: a9e6dc5084627e7c279ba08de7a7809e97ebc539 d78ee736239414021fde8010179f42b86464a238 Which are completely unrelated to the work that Andreas has been doing at the same time (all his commit's from 2012-06-27 on, i.e. 39621c41f303e24b7324dc4c91447a449d2a654b and later. I strongly recomend that you coordinate more and re-view each others' code better. And regarding the messy situatin with master vs. jolly_new: I think the only practical solution is to drop one of the two parallel and incompatible changes regarding the RLC/MAC and TBF establishment changes. Do you have any input on how to resolve this specific issue? I think none of us can afford to waste resources on duplication of work and creating virtually un-mergeable branches :/ Regards, Harald -- - Harald Welte <laforge(a)gnumonks.org> http://laforge.gnumonks.org/ ============================================================================ "Privacy in residential applications is a desirable marketing option."

TBF acknowledged mode is now working

by jolly

hi, finally the TBF acknowledge mode works in up- and downlink. i have tested it with attachment/detachment and routing area update. changes are commited to jolly branch. don't be shocked, but there great changes to previous gprs_rlcmac.cpp code. it is split into three sources: - gprs_rlcmac.cpp: general functions to handle TBF instances, hand-hacked codings - gprs_rlcmac_data.cpp: handling of uplink and downlink TBF - gprs_rlcmac_sched.cpp: scheduler to handle ready-to-send requests. during packet idle mode, assignment of up- or downlink TBF is performed using IMMEDIATE ASSIGMENT on AGCH. during TBF uplink, downlink assignment is performed using PACKET DOWNLINK ASSIGNMENT on PACCH. after TBF downlink, further downlink assignment is performed using PACKET DOWNLINK ASSIGNMENT. during TBF downlink, uplink assignment is performed using PACKET UPLINK assignment. this way an attachment / RA update / detach will complete while staying in packet transfer mode, so no further assignment must be done on AGCH. the acknowledged mode keeps states about transmitted and received blocks, so unreceived or unacknowledged block are retransmitted as defined in TS 04.60. downlink RLC/MAC data and control blocks are not queued, but generated at ready-to-send request from layer 1. a scheduler is used to schedule next RLC/MAC block. it uses round-robin scheduling, if more than two flows are active in one direction. in downlink direction, control blocks are prioized. in uplink direction, polling of mobile is priorized. (USF is set to apply uplink ressource to MS.) only one timeslot (first PDCH) is used to share the ressources, currently. there is a short description (tbf.txt) about states and the process of current code. in order to detect missing responses on polling MS, a gprs_rlcmac_poll_timeout() function is called. layer 1 interface must implement detection of missed polled uplink control blocks. there are two ways to perform this: - The received frame is bad (BFI). - The GSM indicates that the block should have been already received. currently pcu_l1_if.c is broken, because none of the detection above is performed. best regards, andreas

Re: osmo-pcu.git branch jolly updated. f3d060c6310bfa979225b871ba463284d3cda887

by Alexander Chemeris

Hi Andreas, I've looked through your commits and looks like you're doing a very quick progress. Your changes are overlapping with Ivan's work and I would recommend to merge them the master as often as possible to avoid duplicated efforts and code divergence. From this quick review I've got impression that code needs clean up before the merge, so it would be good if you share your plans on this. As a general comment, I think we could do merging of your code into master, but it would be much, much easier if you commit in smaller "atomic" chunks. E.g. these two last commits contain more changes then is written in the commit logs and in my opinion should be splitted into several independent commits. Note, that I just want to share my opinion and it's up to you and Ivan to decide how to work together efficiently.
