[PATCH] Fix issue in encoding CSN_RECURSIVE_ARRAY
by Saurabh Sharan 16 Mar '16

16 Mar '16

The remaining_bits_len is correctly decremented while encoding CSN_RECURSIVE_ARRAY for fixing the bug. Details of the bug is in https://projects.osmocom.org/issues/1641 During introduction of basic EGPRS feature new hex dump message PUASS, from a different working network log was used in Unit test. It exposed the issue of incorrect handling of recursive array encoding in osmo-pcu. --- src/csn1.cpp | 1 + tests/rlcmac/RLCMACTest.cpp | 1 + tests/rlcmac/RLCMACTest.ok | 8 ++++++++ 3 files changed, 10 insertions(+) diff --git a/src/csn1.cpp b/src/csn1.cpp index 82bf17f..d51fe83 100644 --- a/src/csn1.cpp +++ b/src/csn1.cpp @@ -2504,6 +2504,7 @@ gint16 csnStreamEncoder(csnStream_t* ar, const CSN_DESCR* pDescr, bitvec *vector bitvec_write_field(vector, writeIndex, !Tag, 1); LOGPC(DCSN1, LOGL_NOTICE, "%s = %u | ", pDescr->sz , (unsigned)(!Tag)); bit_offset++; + remaining_bits_len--; pDescr++; break; diff --git a/tests/rlcmac/RLCMACTest.cpp b/tests/rlcmac/RLCMACTest.cpp index 26d35ec..466b89e 100644 --- a/tests/rlcmac/RLCMACTest.cpp +++ b/tests/rlcmac/RLCMACTest.cpp @@ -93,6 +93,7 @@ void testRlcMacDownlink() "47240c00400000000000000079eb2ac9402b2b2b2b2b2b", // Packet Uplink Ack Nack "47283c367513ba333004242b2b2b2b2b2b2b2b2b2b2b2b", // Packet Uplink Assignment "400820001a3904df0680efb3300b2b2b2b2b2b2b2b2b2b", // Packet Downlink Assignment (EGPRS) + "40284f0000001009810c826f4406809dcecb2b2b2b2b2b", // Packet Uplink Assignment (EGPRS) "4024030f2f0000000087b0042b2b2b2b2b2b2b2b2b2b2b" // Packet Uplink Ack Nack (EGPRS) "4913e00850884013a8048b2b2b2b2b2b2b2b2b2b2b2b2b" "412430007fffffffffffffffefd19c7ba12b2b2b2b2b2b" diff --git a/tests/rlcmac/RLCMACTest.ok b/tests/rlcmac/RLCMACTest.ok index 4deced7..896982d 100644 --- a/tests/rlcmac/RLCMACTest.ok +++ b/tests/rlcmac/RLCMACTest.ok @@ -39,6 +39,14 @@ vector1 = 4082001a394df680efb330b2b2b2b2b2b2b2b2b2b vector1 = 4082001a394df680efb330b2b2b2b2b2b2b2b2b2b vector2 = 4082001a394df680efb330b2b2b2b2b2b2b2b2b2b vector1 == vector2 : TRUE +vector1 = 40284f00010981c826f446809dcecb2b2b2b2b2b +=========Start DECODE=========== ++++++++++Finish DECODE++++++++++ +=========Start ENCODE============= ++++++++++Finish ENCODE+++++++++++ +vector1 = 40284f00010981c826f446809dcecb2b2b2b2b2b +vector2 = 40284f00010981c826f446809dcecb2b2b2b2b2b +vector1 == vector2 : TRUE vector1 = 40243f2f000087b042b2b2b2b2b2b2b2b2b2b2b =========Start DECODE=========== +++++++++Finish DECODE++++++++++ -- 1.7.9.5

[PATCH] Support of 11 bit RACH
by Bhargava Abhyankar 16 Mar '16

16 Mar '16

This patch is first of series of patches to support 11 bit RACH. This includes interface structure changes between osmo-pcu and osmo-bts to support 11 bit RACH.Processing of 11 bit RACH for GPRS is added in bts.cpp. Unit test for the same shall be sent as separate patch. EGPRS PACKET CHANNEL REQUEST is not part of this patch.Note also that this feature requires changes in osmo-bts and versioning needs to be addressed further. --- src/bts.cpp | 36 +++++++++++++++++++++++++++--------- src/bts.h | 9 ++++++++- src/pcu_l1_if.cpp | 2 +- src/pcuif_proto.h | 3 ++- 4 files changed, 38 insertions(+), 12 deletions(-) diff --git a/src/bts.cpp b/src/bts.cpp index 715fb51..a999c48 100644 --- a/src/bts.cpp +++ b/src/bts.cpp @@ -459,7 +459,7 @@ int BTS::rcv_imm_ass_cnf(const uint8_t *data, uint32_t fn) return 0; } -int BTS::rcv_rach(uint8_t ra, uint32_t Fn, int16_t qta) +int BTS::rcv_rach(uint16_t ra, uint32_t Fn, int16_t qta, uint8_t rach_type) { struct gprs_rlcmac_ul_tbf *tbf = NULL; uint8_t trx_no, ts_no = 0; @@ -475,14 +475,32 @@ int BTS::rcv_rach(uint8_t ra, uint32_t Fn, int16_t qta) LOGP(DRLCMAC, LOGL_DEBUG, "MS requests UL TBF on RACH, so we provide " "one:\n"); - if ((ra & 0xf8) == 0x70) { - LOGP(DRLCMAC, LOGL_DEBUG, "MS requests single block " - "allocation\n"); - sb = 1; - } else if (m_bts.force_two_phase) { - LOGP(DRLCMAC, LOGL_DEBUG, "MS requests single phase access, " - "but we force two phase access\n"); - sb = 1; + + if (rach_type == GPRS_8_BIT_RACH ) { + if ((ra & 0xf8) == 0x70) { + LOGP(DRLCMAC, LOGL_DEBUG, "MS requests single block " + "allocation\n"); + sb = 1; + } else if (m_bts.force_two_phase) { + LOGP(DRLCMAC, LOGL_DEBUG, "MS requests single phase access, " + "but we force two phase access\n"); + sb = 1; + } + + } else if(rach_type == GPRS_11_BIT_RACH ) { + if((ra & RACH_CAUSE_SINGLE_BLOCK) == 0x0600) { + LOGP(DRLCMAC, LOGL_DEBUG, "11 bit RACH received.MS requests single block " + "allocation\n"); + sb = 1; + + } else if (m_bts.force_two_phase) { + LOGP(DRLCMAC, LOGL_DEBUG, "11 bit RACHreceived.MS requests single phase access, " + "but we force two phase access\n"); + sb = 1; + } + } else if (rach_type == EGPRS_11_BIT_RACH) { + /*TODO*/ + } if (qta < 0) qta = 0; diff --git a/src/bts.h b/src/bts.h index c975304..870e6f3 100644 --- a/src/bts.h +++ b/src/bts.h @@ -41,6 +41,7 @@ extern "C" { #define LLC_CODEL_DISABLE 0 #define LLC_CODEL_USE_DEFAULT (-1) +#define RACH_CAUSE_SINGLE_BLOCK ((~((~0) << 6)) << 5) /* Establish cause */ struct BTS; struct GprsMs; @@ -251,6 +252,12 @@ public: TIMER_T3190_MSEC = 5000, }; + enum { + GPRS_8_BIT_RACH = 0, + GPRS_11_BIT_RACH = 1, + EGPRS_11_BIT_RACH = 2, + }; + BTS(); ~BTS(); @@ -275,7 +282,7 @@ public: int tfi_find_free(enum gprs_rlcmac_tbf_direction dir, uint8_t *_trx, int8_t use_trx); int rcv_imm_ass_cnf(const uint8_t *data, uint32_t fn); - int rcv_rach(uint8_t ra, uint32_t Fn, int16_t qta); + int rcv_rach(uint16_t ra, uint32_t Fn, int16_t qta, uint8_t rach_type = 0); void trigger_dl_ass(gprs_rlcmac_dl_tbf *tbf, gprs_rlcmac_tbf *old_tbf); void snd_dl_ass(gprs_rlcmac_tbf *tbf, uint8_t poll, const char *imsi); diff --git a/src/pcu_l1_if.cpp b/src/pcu_l1_if.cpp index 19dda5c..d937d20 100644 --- a/src/pcu_l1_if.cpp +++ b/src/pcu_l1_if.cpp @@ -313,7 +313,7 @@ static int pcu_rx_rach_ind(struct gsm_pcu_if_rach_ind *rach_ind) case PCU_IF_SAPI_RACH: rc = BTS::main_bts()->rcv_rach( rach_ind->ra, rach_ind->fn, - rach_ind->qta); + rach_ind->qta,rach_ind->rach_type); break; default: LOGP(DL1IF, LOGL_ERROR, "Received PCU rach request with " diff --git a/src/pcuif_proto.h b/src/pcuif_proto.h index 9d740ac..0844183 100644 --- a/src/pcuif_proto.h +++ b/src/pcuif_proto.h @@ -64,10 +64,11 @@ struct gsm_pcu_if_rts_req { struct gsm_pcu_if_rach_ind { uint8_t sapi; - uint8_t ra; + uint16_t ra; int16_t qta; uint32_t fn; uint16_t arfcn; + uint8_t rach_type; } __attribute__ ((packed)); struct gsm_pcu_if_info_trx { -- 2.5.0

Padding patch and moving forward with EGPRS support/merge
by Holger Freyther 16 Mar '16

16 Mar '16

Dear Saurabh, it would be nice if you could address the review comment of Harald for the padding patch and send it again. In terms of the commit message it would be interesting to know how you found it, if something broke because of it (e.g. if a specific Handset+Chipset+Firmware release broke). Such information is nicely captured in a commit message and might help future developers to prevent doing a revert or similar. In terms of the EDGE support it is custom in Free Software projects to build on top of what is already present. I don't have a specific approach and there are multiple options but from what I see the situation is: * You seem to have added additional encoding regression tests. It would be nice to move them to the master version and see if the result is similar/correct as well. * Jacob has not implemented compressed bitmaps in the DL TBF handling. The reason is because we want to avoid bufferbloat our windows don't really get that big and it seems we didn't need it yet. Now that you have built a tree based encoder, it might make sense to include the encoder, add tests for the encoding, reason/explain the performance and then hook the encoding in the DL ACK handling. * Any other corrections/fixes you have. * Identify other areas where your support is behaving better than the code in master or features missing and implemented in your branch. Do you already have an idea yourself how you intend to move forward and get your improvements included in the main repository? kind regards holger

[PATCH] Fix encoding of padding bits to start with 0 bit
by Saurabh Sharan 15 Mar '16

15 Mar '16

This patch is for fixing encoding of padding bits according to the 3gpp spec 44.060 section 11, wherein it shall always start with 0 bit followed with spare padding bits. During introduction of basic EGPRS feature new hex dump messages from a different working network log were used in Unit test. These exposed the issue of incorrect handling of padding bits encoding in osmo-pcu. Corrections in the existing test vector of rlcmac is also updated. In testsuite tbf appropriate corrections for the Tbftest.err is also done. --- src/csn1.cpp | 7 ++++++- tests/rlcmac/RLCMACTest.cpp | 6 +++--- tests/rlcmac/RLCMACTest.ok | 18 +++++++++--------- tests/tbf/TbfTest.err | 18 +++++++++--------- 4 files changed, 27 insertions(+), 22 deletions(-)

11 Mar '16

Hello, We are starting to integrate and test NURAN L1 1.0 with osmo-bts / osmo-pcu at Radisys. We downloaded latest osmo-bts master branch. When we checked the code, we see that NURAN specific code is present in osmo-bts/src/osmo-bts-litecell15. When we tried to compile osmo-bts/src/osmo-bts-litecell15 , we see the following error nrw/litecell15/litecell15.h: No such file or directory Let us know if these files are missing or we are missing some steps. Thanks and regards Prasad

[PATCH] Fix encoding of padding bits to start with 0 bit
by Saurabh Sharan 08 Mar '16

08 Mar '16

This patch is for fixing encoding of padding bits according to the 3gpp spec 44.060 section 11, wherein it shall always start with 0 bit followed with spare padding bits. During introduction of basic EGPRS feature new hex dump messages from a different working network log were used in Unit test. These exposed the issue of incorrect handling of padding bits encoding in osmo-pcu. Corrections in the existing test vector and new hex dump vectors shall be submitted in a separate patch. If only this patch is applied rlcmac testsuite will fail for few vectors. --- src/csn1.cpp | 7 ++++++- 1 file changed, 6 insertions(+), 1 deletion(-) diff --git a/src/csn1.cpp b/src/csn1.cpp index 54cc411..82bf17f 100644 --- a/src/csn1.cpp +++ b/src/csn1.cpp @@ -2400,7 +2400,12 @@ gint16 csnStreamEncoder(csnStream_t* ar, const CSN_DESCR* pDescr, bitvec *vector guint8 bits_to_handle = remaining_bits_len%8; if (bits_to_handle > 0) { - guint8 fl = filler&(0xff>>(8-bits_to_handle)); + /* section 11 of 44.060 + * The padding bits may be the 'null' string.

Incorrect Packet Downlink Assignment message in TbfTest.err
by Saurabh Sharan 08 Mar '16

08 Mar '16

Hello All, This mail is to highlight the necessity of the "[PATCH] Fix encoding of padding bits to start with 0 bit" In the latest master osmo-pcu 0.2.752-173e, the identified bug in encoding of padding bits is generating incorrect Control message. Example of an incorrect Packet Downlink Assignment message from the current TbfTest.err log is @ line number 3433 Sending data request: trx=0 ts=4 sapi=5 arfcn=0 fn=0 block=0 data=4f 08 20 00 44 02 00 02 08 04 00 c0 0b 2b 2b 2b 2b 2b 2b 2b 2b 2b 2b Incorrect encoding has resulted in the analyzer interpreting PFI present with value 21. Whereas with the fix for encoding padding bits result is Sending data request: trx=0 ts=4 sapi=5 arfcn=0 fn=0 block=0 data=4f 08 20 00 44 02 00 02 08 04 00 c0 03 2b 2b 2b 2b 2b 2b 2b 2b 2b 2b Output of the message analyzer(http://www.3gpp-message-analyser.com/) is attached in the mail. Please review the patch and let us know procedure for a merge to master. Regards Saurabh

Public Osmocom User Manuals
by Harald Welte 07 Mar '16

07 Mar '16

Dear all, some of you may have already seen it on the RSS feed, on Twitter or on planet.osmocom.org[1]: sysmocom has decided that we will re-release our existing formerly sysmocom-internal User Manuals and VTY reference manuals under GNU GFDL. The hope is that with better documentation we can enable more people to use Osmocom software more easily, leading to more adoption. While those manuals are far from being complete or perfect, I had spent a lot of time in February on further polishing them for the upcoming public release. I do believe they provide a better stasting point than what all of what we had in the wiki (whether old trac or new redmine). The manuals are written in asciidoc[2], with the occasional use of mscgen[3] and graphviz[4], which I believe together are a pretty good set of tools to very efficiently and productively work on documentation, whilst focussing on actual content and not on formatting/syntax like when using docbook-xml or LaTeX. The osmo-gsm-manuals.git repository is pulled by our jenkins installation, which then builds the PDF manuals and pushes them to http://ftp.osmocom.org/docs/latest/ I seriously do hope that we will receive improvements and extensions for the manuals. As the asciidoc source is in yet another git repo, sending patches is as easy as it gets. Holger always states nobody ever contributes to manuals, and I would love to prove him wrong ;) In terms of overlapping information in the wiki and in the manuals: I'm in favor (and in the process) of removing outdated old wiki command line reference and VTY reference sections, and simply referring to the manuals instead. Please do read through the manuals and do send patches, whether it's a spelling fix, improved wording, adding missing information or fixing actual technical mistakes. In tems of further dccumentation improvements, Holger has volunteered to ensure that the Doxygen API of libosmocore is also automatically generated+pushed in a similar fashion to make it publicly web-visible. I'd also encurage everyone to contribute patches to covert those parts of libosmocore.git that don't hve doxygen annotation yet. Thanks in advance!

Clarification on downlink window state variable
by Sangamesh Sajjan 03 Mar '16

03 Mar '16

Hello, Clarification required on Downlink window state GPRS_RLC_DL_BSN_RESEND in OSMO-PCU Could you please let us know the significance of the state GPRS_RLC_DL_BSN_RESEND while handling downlink window. Our understanding is that state GPRS_RLC_DL_BSN_RESEND is used in case of retransmission of UNACKED blocks, which can be done without having GPRS_RLC_DL_BSN_RESEND state. Kindly let us know if we are missing something in our understanding. This will help us in enhancing the state variable handling in FANR (FAST ACK NACK REPORTING) feature. We are planning to introduce new state (i.e GPRS_RLC_DL_BSN_TENTATIVE_ACK ) as part of FANR feature implementation. Thanks & Regards, Sangamesh

Thank you Neels! The "logfile /tmp/foo" did gave an error message saying "unrecognized option". I'm going to look at DNS packets going through a GGSN to try and find ways to detect DNS tunnels, do you have any recommendations how to do this? I do not have the time or resources to use real UE's so I hope to simulate it on a computer using VMs or something like that. I have looked at this: http://openbsc.osmocom.org/trac/wiki/OpenBSC_GPRS as an idea of how to set up the testbed, but I do not know which of the nodes I really need. Do you have any idea?

RE: PCU scheduling and PACCH timeout question
by Saurabh Sharan 01 Mar '16

01 Mar '16

Hello Max, Though I have not analyzed the missing UL poll response, few of my observations from the pcap file attached is mentioned below 1. There seems to be difference in FN UL versus DL being processed at any given time by the order of approx. 10 FNs, example given below a. Packet 7174 , FN 1137361 in DL @ 15:33:22.511809393 b. Packet 7190, FN 1137361 in UL @ 15:33:22.559427972 c. From above example difference in time is 48milliseconds or approx.. 10FN duration 2. For processing DL timeslots 2 to 6 at any given DL FN time taken seems to be approx. 3milliseconds, example given below a. Packet 7174 , FN 1137361 in DL @ 15:33:22.511809393 for TS 2 b. Packet 7178, FN 1137361 in DL @ 15:33:22.514310379 for TS 6 Please let me know if these are known behavior in your integration environment ? These time variations may have an impact on the poll response behavior from MS as well. Regards Saurabh -----Original Message----- From: Max [mailto:msuraev@sysmocom.de] Sent: Thursday, February 25, 2016 3:58 PM To: osmocom-net-gprs(a)lists.osmocom.org; Saurabh Sharan <Saurabh.Sharan(a)radisys.com> Subject: PCU scheduling and PACCH timeout question Hello. I'm trying to debug issue with current OsmoPCU master when some basebands ignore polling requests. The debug output from RLCMAC layer and corresponding .pcap files are attached. The issue appears somewhere after line 112 in debug.log The corresponding packet in pcu.pcapng is 6866 After receiving PACKET_CONTROL_ACK from phone we're trying to schedule polling at FN 1137123 (see packet 6869 in pcap) and than at FN 1137127 (packet 6874) which subsequently fails. This seems suspiciously close but I have not found in the spec yet if this is legitimate thing to do. There are several other occurrences like that in both log and pcap. Have you experienced something like this? Do you have an idea why only some basebands are affected while others work fine? -- Max Suraev <msuraev(a)sysmocom.de<mailto:msuraev@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 Directors: Holger Freyther, Harald Welte

OpenGGSN

Hi Does this mailinglist also regard openGGSN? If so do I have some questions. I have problem setting it up correctly. Does anyone have a configuration file for both ggsn and sgsnemu that works? Which flags are necessary to use and what should they be set to? I understand it can differ based on IP addresses and similar, but can someone please help? I'm using this program for my master thesis. Regards Terje Kristoffer H. Skow

PCU scheduling and PACCH timeout question
by Max 25 Feb '16

25 Feb '16

Hello. I'm trying to debug issue with current OsmoPCU master when some basebands ignore polling requests. The debug output from RLCMAC layer and corresponding .pcap files are attached to ticket http://projects.osmocom.org/issues/1524 The issue appears somewhere after line 112 in debug.log The corresponding packet in pcu.pcapng is 6866 After receiving PACKET_CONTROL_ACK from phone we're trying to schedule polling at FN 1137123 (see packet 6869 in pcap) and than at FN 1137127 (packet 6874) which subsequently fails. This seems suspiciously close but I have not found in the spec yet if this is legitimate thing to do. There are several other occurrences like that in both log and pcap. Have you experienced something like this? Do you have an idea why only some basebands are affected while others work fine? -- Max Suraev <msuraev(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 Directors: Holger Freyther, Harald Welte

[PATCH 1/3] write_queue: Check the result of osmo_wqueue_enqueue and free

The write_queue is designed to have a maximum amount of pending messages and will refuse to take new messages when it has been reached. The caller can decide if it wants to flush the queue and add the message again, create a log. But in all cases the ownership of the msgb has not been transferred.

OsmoBTS - OsmocomBB emulation project
by Dominiq T 11 Apr '15

11 Apr '15

Dear Osmcom, I am working on a project, where I am connecting OsmoBTS with OsmocomBB without hardware. I am trying to remove l1 on both sides and connect OsmoBTS with BB application via simple unix sockets. Based on the further recommendations, I am using osmobts-trx branch. Currently I am able to handle messages between BTS and TRX driver on clock and control ports, and on BB side I am in state that phone wants to connect into a cell (so its waiting for BCCH) . I am now trying to find a possible way how to handle messages on data port , between BTS – TRX ( TRX is removed, there is my application instead), and forward these messages to my customized BB l1 interface . The thing is that I need to send to BB phone (layer23) messages in structures from gsm_04_08.h (i.e. gsm48_system_information_type_3). I am not sure if I will be able to get needed from the messages coming on the data port 5702. I found, that PCU creates unix socket on “/tmp/pcu_bts” , but only in case sysmoBTS is in use (please correct me if I am wrong), so this will be not possible due compilation errors without HW. Here I found the gsm48_system_information_type_3 messages. So basically I need somehow to get this message structures on my custom l1 BB interface. Do you have any idea how to do this ? Any advice will be highly appreciated. Many thanks you for your attention :) Best regards, Dominik Tamaskovic.

Fwd: Running OpenGGSN with UmTRX(Osmobts-trx)

Hi All, I have installed OpenBSC +Osmo-BTS following Osmocom's netwrok from scratch link http://openbsc.osmocom.org/trac/wiki/network_from_scratch Now I would like to implemenet GPRS facility in the testbedusing OpenGGSN and Osmo-SGSN. I am using fairwaves UmDESK for this implementation. I followed the procedure as suggested in the http://openbsc.osmocom.org/trac/wiki/OpenBSC_GPRS with the added modification as suggested in https://wush.net/trac/rangepublic/wiki/fairwaves.gprs But this doesn't seem to work out. Currently the systems execute properly with the following outputs *GGSN Output:* root@nist:/home/nist# ggsn cmdline_parser_configfile listen: 127.0.0.1 conf: /etc/ggsn.conf fg: 1 debug: 1 qos: 0x0b921f apn: internet net: 192.168.0.0/24 dynip: 192.168.0.0/24 pidfile: /var/run/ggsn.pid statedir: /var/lib/ggsn/ timelimit: 0 gtpclient: Initialising GTP tunnel openggsn[3822]: GTP: gtp_newgsn() started Creating tun interface Setting tun IP address *Osmo-SGSN Output:* root@nist:/home/nist# osmo-sgsn -c OpenBSC_GPRS/openbsc/openbsc/src/gprs/osmo_sgsn.cfg <0010> gprs_ns.c:199 NSVCI=65534 Creating NS-VC *Osmo-PCU Output:* root@nist:/home/nist# osmo-pcu No config file: 'osmo-pcu.cfg' Using default config.

The fairwaves.gprs implementation using Chemeris's gprs-work seems to implement with Asterisk as PBX whereas I require it to run with the osmo-nitb. 2. The gprs-work branch still makes use of BTS transceiver and I wanted it to work with the Osmo-nitb implementation using osmobts-trx and osmo-trx Can somebody please help me out with this? Or is there any alternative implementation which can be tried to execute them together. Looking forward to hearing from you, With Regards, Jijo

State of sysmocom/master and upcoming work
by Holger Hans Peter Freyther 16 Jan '14

16 Jan '14

Hi, Daniel and me spent another day in the sysmocom office to go through the PCU code. We finished clean-ups, made some simple manual tests and looked at the traces. We will work on the following items during the next weeks: * For DL handling and multi-slot allocation more than one slot will only be allocated _after_ the TBF is re-used. E.g. for a simple download this might mean a single slot is used for the entire download. Daniel made a prototype to send a packet downlink assignment directly _after_ the assignment through the CCCH has completed. We manage to run into a use after free in the TBF code but will work on it. The issue is that the start of a TBF will take a bit longer. We might want to add some heuristic to decide when or when not to do it. * Re-sending and window stalls. When the entire window has been sent once, resending will start but when the ACK/NACK is arrived the resending will conntinue. As it is more likely that frames have arrived we should stop the resending and increase the window.

Multislot allocation failures and defects
by Holger Hans Peter Freyther 15 Jan '14

15 Jan '14

Dear Andreas, I went through the multislot allocation algorithm and cleaned and structured the code in testable parts that take over parts of the allocation and I have added a unit test for some of the allocation cases (UL first, then DL.. e.g. due a RACH burst and then DL single, UL and DL update). Today morning I added a testcase that tests all PDCH combinations and all MS Classes and verifies that an allocation takes place and that the DL and UL first_common_ts do match. For (xxOxOOxO) and MS_Class=5 this assert is wrong. The alloc/AllocTest of the sysmocom/allocation-cleanups branch should show you this condition. While reading the code I noticed the following things. Could you please explain why these are problems or no problems. * select_first_ts (it exists after the refactoring). It initializes i and compares it but it will never increment it. This means that the code can look at PDCHs _outside_ of the tx_range. * first_common_ts handling. When assigning the DL tbf we pick a first_common_ts but when the actual UL assignment happens there might not be a free USF on the Uplink and at that point the phone might not listen on the TS we think. * Sum for Rx+Tx is not used. I see that in update_rx_win_max you modify the window to make some room. * select_ul_slots. "i" is not incremented in all cases which could potentially lead to using slots outside of the tx_range. For the MS Type == 1 handling you could introduce a different variable that counts how many slots were used? it would be nice if we could fix that during the 30C3. 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

[RFC] [ADMIN] Making lists subscriber-only?
by Harald Welte 15 Jan '14

15 Jan '14

Dear all, so far the osmocom.org mailing lists have always been in a 'non-members are manually moderated' mode. This has created a lot of work for manual list moderation, where a lot of the messages caught are simply spam, and only the occasional valid message is being received. I'd like to thank the list moderators for taking care of this. However, in more recent discussions, we were considering to move the lists to a completely closed mode, i.e. postings would automatically be rejected from non-members. The automatic response would contain a description of how to subscribe in 'nomail' mode, i.e. to subscribe in a way to be able to post to the list, while still not receiving any incoming traffic. The latter should be fine for occasional posters who don't want the bulk e-mail that goes with a full/regular subscription. Please provide feedback in case you disagree with that change. Unless there is major opposition, we will likely transition to the 'closed' mode within one month.

Status of sysmocom/master W50
by Holger Hans Peter Freyther 25 Dec '13

25 Dec '13

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 06 Dec '13

06 Dec '13

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 27 Nov '13

27 Nov '13

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 19 Nov '13

19 Nov '13

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 07 Nov '13

07 Nov '13

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?

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 31 Oct '13

31 Oct '13

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 28 Oct '13

28 Oct '13

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

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 17 Oct '13

17 Oct '13

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 17 Oct '13

17 Oct '13

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 16 Oct '13

16 Oct '13

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, };

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 24 Aug '13

24 Aug '13

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 05 Aug '13

05 Aug '13

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..).

osmo_timer_del is an idempotent operation. There is no requirement to check if it is running. If you don't want a timer to run, delete it.

Weird usage of gprs_ns_vty_init from gprs_bssgp_create
by Holger Hans Peter Freyther 12 Jul '13

12 Jul '13

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 02 Mar '13

02 Mar '13

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 26 Feb '13

26 Feb '13

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 19 Feb '13

19 Feb '13

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 30 Jan '13

30 Jan '13

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.

lack of progress in PCU patch merging / git (ab)use
by Harald Welte 17 Jan '13

17 Jan '13

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 16 Jan '13

16 Jan '13

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.

openbts-p2.8-gprs-exp and pcu issues
by Vladimir Rolbin 28 Oct '12

28 Oct '12

Hi Ivan. More pcu logs (Nokia 5000d-2). At the begining everything is ok (PACKET CONTROL ACK with expected FN only), but from line 1248 frome the start of log something occurs and a lot of "PACKET DOWNLINK ACK with unknown FN" appears. Possibly timing problems.. <0001> pcu_l1_if.cpp:334 BTS available <0001> pcu_l1_if.cpp:335 mcc=452 <0001> pcu_l1_if.cpp:336 mnc=2 <0001> pcu_l1_if.cpp:337 lac=1000 <0001> pcu_l1_if.cpp:338 rac=0 <0001> pcu_l1_if.cpp:339 cell_id=0 <0001> pcu_l1_if.cpp:340 nsei=8 <0001> pcu_l1_if.cpp:345 nse_timer=0 0 0 0 0 0 0 <0001> pcu_l1_if.cpp:353 cell_timer=0 0 0 0 0 0 0 0 0 0 0 <0001> pcu_l1_if.cpp:354 repeat_time=5 <0001> pcu_l1_if.cpp:355 repeat_count=10 <0001> pcu_l1_if.cpp:356 bvci=7 <0001> pcu_l1_if.cpp:357 t3142=20 <0001> pcu_l1_if.cpp:358 t3169=5 <0001> pcu_l1_if.cpp:359 t3191=5 <0001> pcu_l1_if.cpp:360 t3193=1000 (ms) <0001> pcu_l1_if.cpp:361 t3195=5 <0001> pcu_l1_if.cpp:362 n3101=10 <0001> pcu_l1_if.cpp:363 n3103=4 <0001> pcu_l1_if.cpp:364 n3105=8 <0001> pcu_l1_if.cpp:365 cv_countdown=15 <0001> pcu_l1_if.cpp:366 dl_tbf_ext=0 <0001> pcu_l1_if.cpp:367 ul_tbf_ext=0 <0001> pcu_l1_if.cpp:376 initial_cs=1 <0001> pcu_l1_if.cpp:377 initial_mcs=0 <0001> pcu_l1_if.cpp:378 nsvci=4 <0001> pcu_l1_if.cpp:379 local_port=5944 <0001> pcu_l1_if.cpp:380 remote_port=23000 <0001> pcu_l1_if.cpp:381 remote_ip=2130706433 <0008> gprs_bssgp_pcu.cpp:611 bctx mcc=452 <0008> gprs_bssgp_pcu.cpp:612 bctx mnc=2 <0001> pcu_l1_if.cpp:82 Sending activate request: trx=0 ts=7 <0001> pcu_l1_if.cpp:429 PDCH: trx=0 ts=7 <0009> gprs_bssgp_pcu.cpp:491 NS-VC 4 is unblocked. <0008> gprs_bssgp_pcu.cpp:532 Sending reset on BVCI 0 <0008> gprs_bssgp_pcu.cpp:540 Sending reset on BVCI 7 <0008> gprs_bssgp_pcu.cpp:548 Sending unblock on BVCI 7 <0001> pcu_l1_if.cpp:256 RACH request received: sapi=1 qta=0, ra=123, fn=153643 <0002> gprs_rlcmac.cpp:354 Allocating UL TBF: TFI=0 TRX=0 MS_CLASS=0 <0002> gprs_rlcmac.cpp:948 - Setting Control TS 7 <0002> gprs_rlcmac_data.cpp:1183 TX: START TFI: 0 Immediate Assignment Uplink (AGCH) <0002> gprs_rlcmac_data.cpp:1895 Got IMM.ASS confirm, but rest octets do not start with bit sequence 'HH01' (Packet Downlink Assignment) <0005> gprs_rlcmac_data.cpp:896 Decoded premier TLLI=0xb9e1d899 of UL DATA TBF=0. <0005> gprs_rlcmac_data.cpp:759 Complete UL frame for TBF=0: len=44 <0008> gprs_rlcmac.cpp:1760 LLC [PCU -> SGSN] TFI: 0 TLLI: 0xb9e1d899 len=44 <0008> gprs_bssgp_pcu.cpp:145 LLC [SGSN -> PCU] = TLLI: 0xb9e1d899 IMSI: 000 len: 9 <0002> gprs_rlcmac.cpp:354 Allocating DL TBF: TFI=0 TRX=0 MS_CLASS=10 <0002> gprs_rlcmac.cpp:948 - Setting Control TS 7 <0002> gprs_rlcmac_data.cpp:1783 TBF: START TFI: 0 TLLI: 0xb9e1d899 Packet Downlink Assignment (PACCH) <0006> gprs_rlcmac_sched.cpp:260 Received RTS for PDCH: TRX=0 TS=7 FN=153716 block_nr=1 scheduling free USF for polling at FN=153720 of UL TFI=0 <0002> gprs_rlcmac_data.cpp:307 PACKET CONTROL ACK with expected FN=153720 TLL=0xb9e1d899 (TRX 0 TS 7) <0004> gprs_rlcmac_data.cpp:1472 Complete DL frame for TBF=0: len=9 <0006> gprs_rlcmac_sched.cpp:260 Received RTS for PDCH: TRX=0 TS=7 FN=153746 block_nr=8 scheduling free USF for polling at FN=153751 of UL TFI=0 <0006> gprs_rlcmac_sched.cpp:260 Received RTS for PDCH: TRX=0 TS=7 FN=153751 block_nr=9 scheduling free USF for polling at FN=153755 of DL TFI=0 <0002> gprs_rlcmac_data.cpp:307 PACKET CONTROL ACK with expected FN=153751 TLL=0xb9e1d899 (TRX 0 TS 7) <0002> gprs_rlcmac.cpp:895 Free UL TBF=0 with TLLI=0xb9e1d899. <0001> pcu_l1_if.cpp:256 RACH request received: sapi=1 qta=0, ra=124, fn=153895 <0002> gprs_rlcmac.cpp:354 Allocating UL TBF: TFI=0 TRX=0 MS_CLASS=0 <0002> gprs_rlcmac.cpp:948 - Setting Control TS 7 <0002> gprs_rlcmac_data.cpp:1183 TX: START TFI: 0 Immediate Assignment Uplink (AGCH) <0002> gprs_rlcmac_data.cpp:1895 Got IMM.ASS confirm, but rest octets do not start with bit sequence 'HH01' (Packet Downlink Assignment) <0005> gprs_rlcmac_data.cpp:896 Decoded premier TLLI=0xb9e1d899 of UL DATA TBF=0. <0005> gprs_rlcmac_data.cpp:901 Got RACH from TLLI=0xb9e1d899 while DL TBF=0 still exists.

bug in wireshark decoder of osmo-pcu
by jolly 11 Oct '12

11 Oct '12

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 26 Jul '12

26 Jul '12

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 25 Jul '12

25 Jul '12

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 25 Jul '12

25 Jul '12

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
