This is an automated email from the git hooks/post-receive script. It was generated because a ref change was pushed to the repository containing the project "The OpenBSC GSM Base Station Controller (+MSC/HLR/SGSN)". The branch, master has been updated via 743dec4c0c80383556efac60f03d307287ecf024 (commit) via 65fa3f73a1151e896e4c74196680b7886a3b6be6 (commit) via 69d271376cce7d26a0469bbb948f272c399ac6c7 (commit) via cde0bb27a14553bba2f680cd1307a5f9b3581f0e (commit) via 058bc26e1bb1350c9077f99edd24887bb84bc8c5 (commit) via c157ee7d2ccdb7524e76d25b22cb7eec8de9a656 (commit) via 0f47b8fae743769a6627f8654444b4f0d665e050 (commit) via b8fb1409d1ed18dc198b430895a74e680640c2b1 (commit) via e1beb6f51d3822593d56e071d47e12a74f077826 (commit) via d3cde1ecf49940fae90ec5e1d36824ee0ba17501 (commit) via f06fe29f61c0089ca2f0c10faea18c65d5014f95 (commit) via bf34c67f3f5f747d71f844aec9ae61d26b273d6d (commit) via 42755785707a11c8349b86c2afb98b7bc15c85dc (commit) via bce2061b43c1e38b766cc3738b4ad669211dc6a4 (commit) via 9aa9991efe207f5c12bbcf655b0660e3466c02e0 (commit) via af3d5c508c9ca3ebae9388d3e09c5d7726db4f5c (commit) via afcf23001e600bedc51db08a22846dada9bc06b3 (commit) via 8054799963f4b3b936d601eb4b1f5774f2c41fec (commit) via 03b463034885e7ebb09160f6d63c05ac120a8098 (commit) via e154d8bdd45974fa6e9408b9d543eb9e9ea94b79 (commit) via 69e16b9ea5dc991f8373c11b9fcf45b7b1a8e940 (commit) via 4188c30c4a6574201d62df1be818eed038608d16 (commit) via 849d0a83e8598e0f21a3e9c5438c222d8ab417eb (commit) via 7660ffa29fb463fc24b2ac8d735b9b345017bba6 (commit) via 3d722450de1cf34931d95f7a748a9b6c48e933f0 (commit) via e21e184d84d6a932b58079084d254f498599e29e (commit) via 771573c535ae97ce7c7ed7694670e3b98eeae48a (commit) via a071c1ccc07074272f6cb7626b781f45f85564c6 (commit) via 9d4f46c975c3a4c92071c70ebadd6edc345581da (commit) via 39f040d62b16b2d99352f5facd83ce098fa2f462 (commit) via bb23dc17f8f56be836dc50c925c04a5aeaec979c (commit) via 1610626fe9e65693c6d8743129b10ed4958ec6ea (commit) via a2315eebf972412e122033ac036dd21bcdad5335 (commit) via 424ffa480630a4242d2a6f6b27b9e6b1ec08d206 (commit) via 0572ee045d1b7c29a0c34b27867b3f8669eb5038 (commit) via f0b06d82cd6f2a340db052a2fa2e559aa75f1fa8 (commit) via 07de92e2c0ccfa89b9498c8c49a74d0848b7b85a (commit) from a6ddc2d99f8463edb0b5eacf080db0b5ca571efc (commit) Those revisions listed above that are new to this repository have not appeared on any other notification email; so we list those revisions in full, below. - Log ----------------------------------------------------------------- http://cgit.osmocom.org/openbsc/commit/?id=743dec4c0c80383556efac60f03d3072… commit 743dec4c0c80383556efac60f03d307287ecf024 Author: Jacob Erlbeck <jerlbeck(a)sysmocom.de> Date: Thu Jan 8 15:18:39 2015 +0100 gprs: Retry PURGE_MS procedure after timeout Currently, when the PURGE_MS_REQ to the HLR gets lost (e.g. by a connection or peer failure), the expired subscriber entry will not get deleted. This commit adds a retry mechanism then restarts the procedure after a timeout (currently 10s). The maximum number of retries is limited (currently to 3 PURGE_MS messages). If none of these procedures is completed (either with success or error), the subscriber data is deleted.

For this purpose, MAP defines the PURGE MS procedure (see GSM 09.02, 19.1.4). This patch adds support for the PURGE_MS_REQ/_ERR/_RES messages and invokes the procedure when the subscriber entry is going to be removed. This only applies if GSUP is being used, the Update Location procedure has been completed successfully, and the subscriber has not been cancelled. The removal of the entry is delayed until a PURGE_MS_RES or PURGE_MS_ERR message is received. Note that GSM 09.02, 19.1.4.4 implies that the subscriber data is not to be removed when the procedure fails which is not the way the feature has been implemented. Note that handling 'P-TMSI freezing' is not implemented.

If cancelled, the subscriber will be deleted immediately and no timeout will be set. If the expiry time is set to SGSN_TIMEOUT_NEVER, no timer will be started and the subscriber entry will be kept until it is cancelled. The following VTY command is added to the sgsn node: - subscriber-expiry-time <0-999999> set expiry time in seconds - no subscriber-expiry-time set to SGSN_TIMEOUT_NEVER The default is an expiry time of 0 seconds, which means that the subscriber entries are wiped out immediately after an MM context is destroyed. Note that unused MM contexts are not expired yet. Therefore the subscriber will only be expired after a successful MM detach.

On the other hand, GSM 04.08/24.008, 4.7.3.1.4 in combination with 4.7.3.1.5, require the MS to retry the attachment procedure for cause codes above 15 instead of disabling GPRS. All of the mentioned GMM causes have codes above 15, so using a REJECT message including the cause code is a better choice. This way, the retry algorithm based on T3311 (15s, 5 times) and T3302 (default 12min) could be used. This patch modifies gprs_subscr_handle_gsup_auth_err and gprs_subscr_handle_gsup_upd_loc_err to proceed like when the access has beed denied, except that the corresponding subscriber's information fields are not cleared. This has been successfully tested which an iphone which enters a retry loop as it is being described in the specification.

Albeit all error return codes are negative, the semantics of the absolute value are not clearly defined. In addition, some return codes are not passed to the calling function. This path changes these functions to always return a negated GMM cause value in case of errors. Return values of called parser functions are not longer ignored.

This means, that an MS will not retry to attach even on temporary network errors. This patch changes these functions to use the GSUP error cause value to decide, whether to clear the corresponding subscriber fields, to just continue with the corresponding update function, or to log, ignore and not pass the cause to the MS in case the error is directly related to the GSUP protocol. The subscriber's error_cause field is updated, if the update function is going to be called. The error_cause fielt is reset on non-error GSUP messages.

These are then passed to the MS, unless gsm0408_gprs_access_cancelled is called with cause 0 (no error -> updateProcedure). Since gsm0408_gprs_access_denied uses GMM_CAUSE_GPRS_NOTALLOWED if the cause is not set, and the subscriber's error_cause is never set (and thus always 0), the SGSN's behaviour does not change with this patch.

That is to say, the old revision is not a strict subset of the new revision. This situation occurs when you --force push a change and generate a repository containing something like this: * -- * -- B -- O -- O -- O (64d0007aca0bc5f3c53aa3e710d9db6b745af36e) \ N -- N -- N (e0eb96d6a712a0278ecd00b7a1a9ba9685c306bf) When this happens we assume that you've already had alert emails for all of the O revisions, and so we here report only the revisions in the N branch from the common base, B. Those revisions listed above that are new to this repository have not appeared on any other notification email; so we list those revisions in full, below. - Log ----------------------------------------------------------------- http://cgit.osmocom.org/openbsc/commit/?id=e0eb96d6a712a0278ecd00b7a1a9ba96… commit e0eb96d6a712a0278ecd00b7a1a9ba9685c306bf Author: Jacob Erlbeck <jerlbeck(a)sysmocom.de> Date: Thu Jan 15 18:51:31 2015 +0100 sgsn: Fix P-TMSI generator's periodicity Currently sgsn_alloc_ptmsi uses rand() to get a new P-TMSI and then sets to upper 2 MSB. Therefore there is no lower limit of the distance between 2 identical P-TMSI. This patch changes the implementation to discard any random value above 2^30 and to generate a new random number in that case until a fitting number is found (or a repetition limit is reached). This way, all number below 2^30 within the PRNG's period are used.

This behaviour is not compliant to GSM 09.02, 20.3.3.2 (Subscriber data management/SGSN) where it is defined, that an error ("Unidentified subscriber") shall be returned. This patch removes the case distinction, so that an existing subscriber entry is required for all incoming GSUP messages.

This patch adds GSUP error replies for these requests (and only for requests). It also adds tests for these cases. Note that several of these tests check for GMM_CAUSE_MSGT_NOTEXIST_NOTIMPL, which will have to be changed, when the features are implemented.

If an Update Location or a Send Auth Info Req procedure is not started because of blocking, the retry mechanism is aborted to shorten the blocking time.

This commit adds a retry mechanism then restarts the procedure after a timeout (currently 10s). The maximum number of retries is limited (currently to 3 PURGE_MS messages). If none of these procedures is completed (either with success or error), the subscriber data is deleted.

For this purpose, MAP defines the PURGE MS procedure (see GSM 09.02, 19.1.4). This patch adds support for the PURGE_MS_REQ/_ERR/_RES messages and invokes the procedure when the subscriber entry is going to be removed. This only applies if GSUP is being used, the Update Location procedure has been completed successfully, and the subscriber has not been cancelled. The removal of the entry is delayed until a PURGE_MS_RES or PURGE_MS_ERR message is received. Note that GSM 09.02, 19.1.4.4 implies that the subscriber data is not to be removed when the procedure fails which is not the way the feature has been implemented. Note that handling 'P-TMSI freezing' is not implemented.

This patch adds support for the PURGE_MS_REQ/_ERR/_RES messages and invokes the procedure when the subscriber entry is going to be removed. This only applies if GSUP is being used, the Update Location procedure has been completed successfully, and the subscriber has not been cancelled. The removal of the entry is delayed until a PURGE_MS_RES or PURGE_MS_ERR message is received.

If cancelled, the subscriber will be deleted immediately and no timeout will be set. If the expiry time is set to SGSN_TIMEOUT_NEVER, no timer will be started and the subscriber entry will be kept until it is cancelled. The following VTY command is added to the sgsn node: - subscriber-expiry-time <0-999999> set expiry time in seconds - no subscriber-expiry-time set to SGSN_TIMEOUT_NEVER The default is an expiry time of 0 seconds, which means that the subscriber entries are wiped out immediately after an MM context is destroyed. Note that unused MM contexts are not expired yet. Therefore the subscriber will only be expired after a successful MM detach.

On the other hand, GSM 04.08/24.008, 4.7.3.1.4 in combination with 4.7.3.1.5, require the MS to retry the attachment procedure for cause codes above 15 instead of disabling GPRS. All of the mentioned GMM causes have codes above 15, so using a REJECT message including the cause code is a better choice. This way, the retry algorithm based on T3311 (15s, 5 times) and T3302 (default 12min) could be used. This patch modifies gprs_subscr_handle_gsup_auth_err and gprs_subscr_handle_gsup_upd_loc_err to proceed like when the access has beed denied, except that the corresponding subscriber's information fields are not cleared.

This means, that an MS will not retry to attach even on temporary network errors. This patch changes these functions to use the GSUP error cause value to decide, whether to clear the corresponding subscriber fields, to just continue with the corresponding update function, or to log, ignore and not pass the cause to the MS in case the error is directly related to the GSUP protocol.

Since gsm0408_gprs_access_denied uses GMM_CAUSE_GPRS_NOTALLOWED if the cause is not set, and the subscriber's error_cause is never set (and thus always 0), the SGSN's behaviour does not change with this patch.

Especially list elements (auth tuples and pdp info) are not replaced by an IE, but the IE is appended. This patch uses the assignment operator to clear gprs_gsup_message, gsm_auth_tuple, and gprs_gsup_pdp_info before using them. This also replaces the use of memcpy of the latter.

The function fails, if the GSUP message length (not including IPA headers) is 0. In this case, a segfault can happen, depending on the value of the uninitialized 'value' pointer. The test case doesn't trigger a segfault, but valgrind complains about reading uninitialized data. This patch adds a check for the return value that would return with an error code if the shift function failed.

That is to say, the old revision is not a strict subset of the new revision. This situation occurs when you --force push a change and generate a repository containing something like this: * -- * -- B -- O -- O -- O (fc376259e0a306d41e17cab43de7c2a4796f9aba) \ N -- N -- N (89b5af1f8d450e039602030d06ea6b0bd62925a2) When this happens we assume that you've already had alert emails for all of the O revisions, and so we here report only the revisions in the N branch from the common base, B. Those revisions listed above that are new to this repository have not appeared on any other notification email; so we list those revisions in full, below. - Log ----------------------------------------------------------------- http://cgit.osmocom.org/openbsc/commit/?id=89b5af1f8d450e039602030d06ea6b0b… commit 89b5af1f8d450e039602030d06ea6b0bd62925a2 Author: Jacob Erlbeck <jerlbeck(a)sysmocom.de> Date: Tue Sep 30 13:53:26 2014 +0200 sgsn: Added TODOs (TODO) TODO: - fix and remove TODOs - add test cases for Detach(reattach) - add test cases for PDP context deletion (OW#1311) - add test cases for Cancel pending timer in sgsn_mm_ctx_free - implement age based MM context expiry - remove this commit Sponsored-by: On-Waves ehf http://cgit.osmocom.org/openbsc/commit/?id=488cc66679e20973fc85c4bc9a39eacf… commit 488cc66679e20973fc85c4bc9a39eacf46548f80 Author: Jacob Erlbeck <jerlbeck(a)sysmocom.de> Date: Fri Oct 17 10:08:02 2014 +0200 sgsn: Do not die in _bssgp_tx_dl_ud on TLLI mismatch (TODO) Currently an OSMO_ASSERT fails, if the message's and the mmctx's TLLIs do not match.

For this purpose, MAP defines the PURGE MS procedure (see GSM 09.02, 19.1.4). This patch adds support for the PURGE_MS_REQ/_ERR/_RES messages and invokes the procedure when the subscriber entry is going to be removed. This only applies if GSUP is being used, the Update Location procedure has been completed successfully, and the subscriber has not been cancelled. The removal of the entry is delayed until a PURGE_MS_RES or PURGE_MS_ERR message is received.

If cancelled, the subscriber will be deleted immediately and no timeout will be set. If the expiry time is set to SGSN_TIMEOUT_NEVER, no timer will be started and the subscriber entry will be kept until it is cancelled. The following VTY command is added to the sgsn node: - subscriber-expiry-time <0-999999> set expiry time in seconds - no subscriber-expiry-time set to SGSN_TIMEOUT_NEVER The default is an expiry time of 0 seconds, which means that the subscriber entries are wiped out immediately after an MM context is destroyed. Note that unused MM contexts are not expired yet. Therefore the subscriber will only be expired after a successful MM detach.

That is to say, the old revision is not a strict subset of the new revision. This situation occurs when you --force push a change and generate a repository containing something like this: * -- * -- B -- O -- O -- O (2eb4ee28fce464f60231209d4cacfa18400ac9a6) \ N -- N -- N (fc376259e0a306d41e17cab43de7c2a4796f9aba) When this happens we assume that you've already had alert emails for all of the O revisions, and so we here report only the revisions in the N branch from the common base, B. Those revisions listed above that are new to this repository have not appeared on any other notification email; so we list those revisions in full, below. - Log ----------------------------------------------------------------- http://cgit.osmocom.org/openbsc/commit/?id=fc376259e0a306d41e17cab43de7c2a4… commit fc376259e0a306d41e17cab43de7c2a4796f9aba Author: Jacob Erlbeck <jerlbeck(a)sysmocom.de> Date: Tue Sep 30 13:53:26 2014 +0200 sgsn: Added TODOs (TODO) TODO: - fix and remove TODOs - add test cases for Detach(reattach) - add test cases for PDP context deletion (OW#1311) - add test cases for Cancel pending timer in sgsn_mm_ctx_free - remove this commit Sponsored-by: On-Waves ehf http://cgit.osmocom.org/openbsc/commit/?id=bf5805ff4d5e0433185811a359baccc2… commit bf5805ff4d5e0433185811a359baccc2e73f32ce Author: Jacob Erlbeck <jerlbeck(a)sysmocom.de> Date: Fri Oct 17 10:08:02 2014 +0200 sgsn: Do not die in _bssgp_tx_dl_ud on TLLI mismatch (TODO) Currently an OSMO_ASSERT fails, if the message's and the mmctx's TLLIs do not match.

For this purpose, MAP defines the PURGE MS procedure (see GSM 09.02, 19.1.4). This patch adds support for the PURGE_MS_REQ/_ERR/_RES messages and invokes the procedure when the subscriber entry is going to be removed. This only applies, if GSUP is being used, the Update Location procedure has been completed successfully, and the subscriber has not been cancelled. The removal of the entry is delayed until a PURGE_MS_RES or PURGE_MS_ERR message is received.

If the expiry time is set to SGSN_TIMEOUT_NEVER, no timer will be started and the subscriber entry will be kept until it is cancelled. The following VTY command is added to the sgsn node: - subscriber-expiry-time <0-999999> set expiry time in seconds - no subscriber-expiry-time set to SGSN_TIMEOUT_NEVER The default is an expiry time of 0 seconds, which means that the subscriber entries are wiped out immediately after an MM context is destroyed.

On the other hand, GSM 04.08/24.008, 4.7.3.1.4 in combination with 4.7.3.1.5, require the MS to retry the attachment procedure for cause codes above 15 instead of disabling GPRS. All of the mentioned GMM causes have codes above 15, so using a REJECT message including the cause code is a better choice. This way, the retry algorithm based on T3311 (15s, 5 times) and T3302 (default 12min) could be used. This patch modifies gprs_subscr_handle_gsup_auth_err and gprs_subscr_handle_gsup_upd_loc_err to proceed like when the access has beed denied, except that the corresponding subscriber's information fields are not cleared. This has been successfully tested which an iphone which enters a retry loop as it is being described in the specification.

This means, that an MS will not retry to attach even on temporary network errors. This patch changes these functions to use the GSUP error cause value to decide, whether to clear the corresponding subscriber fields, to just continue with the corresponding update function, or to log, ignore and not pass the cause to the MS in case the error is directly related to the GSUP protocol.

These are then passed to the MS, unless gsm0408_gprs_access_cancelled is called with cause 0 (no error -> updateProcedure). Since gsm0408_gprs_access_denied uses GMM_CAUSE_GPRS_NOTALLOWED if the cause is not set, and the subscriber's error_cause is never set (and thus always 0), the SGSN's behaviour does not change with this patch.

This patch adds a timer based PING mechanism that regularly sends PING messages and forces a reconnect if a PONG message won't be received until the next PING message is scheduled. The current ping interval is 20s.

This means, that the client doesn't answer to PING and ID_GET and logs notices when receiving PONG or ID_ACK. At least the PING functionality (remotely originated PING) shall be supported. This patch extends gsup_client_read_cb by a call to ipaccess_bts_handle_ccm. Only when the return code is 0, the message is processed further and checked for an OSMO/GSUP message. ID_GET messages are answered by a dummy description, where only the unit_name is set to 'SGSN'.

In either case, the application gets informed about the connection state via the updown_cb. The 'up' parameter is only set, if poll/select consider the socket as writable. This patch handles both cases equally and fully relies on the updown_cb to adjust the gsupc obejct state.

The MS has probably sent several Attach Requests while the connection was down and will continue doing so. Therefore these stored messages could be dropped. This patch clears the queue before re-connecting and also extends gprs_gsup_client_send to return immediately, when the connection is not established instead of calling ipa_client_conn_send.

This commit adds a timer based connection mechanism, basically consisting of a timer callback that calls gsup_client_connect. The timer is eventually triggered (up == 0) or cleared (up != 0) by gsup_client_updown_cb. It adds calls to osmo_timer_del() to gsup_client_connect and gprs_gsup_client_destroy. The latter is now called instead of talloc_free in gprs_gsup_client_create on error to be on the safe side.

That is to say, the old revision is not a strict subset of the new revision. This situation occurs when you --force push a change and generate a repository containing something like this: * -- * -- B -- O -- O -- O (e2e2ef39a05b6840b6670ca8e1f1d889bafffdb6) \ N -- N -- N (2eb4ee28fce464f60231209d4cacfa18400ac9a6) When this happens we assume that you've already had alert emails for all of the O revisions, and so we here report only the revisions in the N branch from the common base, B. Those revisions listed above that are new to this repository have not appeared on any other notification email; so we list those revisions in full, below. - Log ----------------------------------------------------------------- http://cgit.osmocom.org/openbsc/commit/?id=2eb4ee28fce464f60231209d4cacfa18… commit 2eb4ee28fce464f60231209d4cacfa18400ac9a6 Author: Jacob Erlbeck <jerlbeck(a)sysmocom.de> Date: Tue Sep 30 13:53:26 2014 +0200 sgsn: Added TODOs (TODO) TODO: - fix and remove TODOs - add test cases for Detach(reattach) - add test cases for PDP context deletion (OW#1311) - add test cases for Cancel pending timer in sgsn_mm_ctx_free - remove this commit Sponsored-by: On-Waves ehf http://cgit.osmocom.org/openbsc/commit/?id=11c8dcd10f3fd98f054ef2918d497982… commit 11c8dcd10f3fd98f054ef2918d49798274ffbfd8 Author: Jacob Erlbeck <jerlbeck(a)sysmocom.de> Date: Fri Oct 17 10:08:02 2014 +0200 sgsn: Do not die in _bssgp_tx_dl_ud on TLLI mismatch (TODO) Currently an OSMO_ASSERT fails, if the message's and the mmctx's TLLIs do not match.

This only applies, if GSUP is being used, the Update Location procedure has been completed successfully, and the subscriber has not been cancelled.

On the other hand, GSM 04.08/24.008, 4.7.3.1.4 in combination with 4.7.3.1.5, require the MS to retry the attachment procedure for cause codes above 15 instead of disabling GPRS. All of the mentioned GMM causes have codes above 15, so using a REJECT message including the cause code is a better choice. This way, the retry algorithm based on T3311 (15s, 5 times) and T3302 (default 12min) could be used. This patch modifies gprs_subscr_handle_gsup_auth_err and gprs_subscr_handle_gsup_upd_loc_err to proceed like when the access has beed denied, except that the corresponding subscriber's information fields are not cleared.

This means, that an MS will not retry to attach even on temporary network errors. This patch changes these functions to use the GSUP error cause value to decide, whether to clear the corresponding subscriber fields, to just continue with the corresponding update function, or to log, ignore and not pass the cause to the MS in case the error is directly related to the GSUP protocol. The subscriber's error_cause field is updated, if the update function is going to be called. The error_cause fielt is reset on non-error GSUP messages.

Especially list elements (auth tuples and pdp info) are not replaced by an IE, but the IE is appended. This patch uses the assignment operator to clear gprs_gsup_message, gsm_auth_tuple, and gprs_gsup_pdp_info before using them. This also replaces the use of memcpy of the latter.

The function fails, if the GSUP message length (not including IPA headers) is 0. In this case, a segfault can happen, depending on the value of the uninitialized 'value' pointer. The test case doesn't trigger a segfault, but valgrind complains about reading uninitialized data. This patch adds a check for the return value that would return with an error code if the shift function failed.

When connecting assume that the ASYNC connect worked directly as otherwise we get no notification of the failure.

On the other hand, GSM 04.08/24.008, 4.7.3.1.4 in combination with 4.7.3.1.5, require the MS to retry the attachment procedure for cause codes above 15 instead of disabling GPRS. All of the mentioned GMM causes have codes above 15, so using a REJECT message including the cause code is a better choice. This way, the retry algorithm based on T3311 (15s, 5 times) and T3302 (default 12min) could be used. This patch modifies gprs_subscr_handle_gsup_auth_err and gprs_subscr_handle_gsup_upd_loc_err to proceed like when the access has beed denied, except that the corresponding subscriber's information fields are not cleared. This has been successfully tested which an iphone which enters a retry loop as it is being described in the specification.

This relies on subscr->mm being set to include the IMSI in the output. This also means, that in doesn't show the IMSI in subscr entries that are not attached to an MM context, albeit the IMSI is stored in the gsm_subscriber object. This patch adds a new logging macro, that logs subscrs to DGPRS without using the mm reference. It also replaces all LOGMMCTXP and most LOGP in gprs_subscriber.c by LOGGSUBSCRP.

The error is the difference between the TCXO and GPS. We need to correct by the reverse of the error. This seems to be different depending on the clock source we have.

It can be triggered from the VTY of the sysmobts-mgr right now.

The sysmobts-mgr code first needs to determine if the clock adjustment is necessary at all. This is done by first resetting the counters, then waiting, then asking for the diff and then applying the correction value. But the reference clock is only set by the application comand. Copy more code of l1if_rf_clock_info_reset to set the reference clock as value. This is leaving some todos inside the code that will be resolved as part of SYS#835.

The first step is to open (and re-open) the control connection to the BTS. As the connection is on localhost there should not be a computation overhead to always have the connection open. When connecting assume that the ASYNC connect worked directly as otherwise we get no notification of the failure. This looks like a "bug" of libosmo-abis that should check if the socket has been connected or not. http://cgit.osmocom.org/osmo-bts/commit/?id=d81b78b524c823122d569fc09f4a764… commit d81b78b524c823122d569fc09f4a764b7a2e13f2 Author: Holger Hans Peter Freyther <holger(a)moiji-mobile.com> Date: Fri Dec 12 16:54:08 2014 +0100 msg: Generalize the message structure test This was taken out of LaF0rge's OML router branch and is now used by the extended calibration feature. ----------------------------------------------------------------------- Summary of changes: include/osmo-bts/Makefile.am | 2 +- include/osmo-bts/cbch.h | 16 +++ include/osmo-bts/gsm_data.h | 6 + src/common/Makefile.am | 3 +- src/common/bts.c | 2 + src/common/cbch.c | 196 +++++++++++++++++++++++++++ src/common/measurement.c | 4 + src/common/oml.c | 18 ++- src/common/rsl.c | 33 ++++- src/common/support.c | 4 + src/common/vty.c | 15 +- src/osmo-bts-sysmo/l1_if.c | 5 + src/osmo-bts-sysmo/misc/sysmobts_mgr_calib.c | 21 ++- src/osmo-bts-sysmo/misc/sysmobts_mgr_nl.c | 11 +- src/osmo-bts-sysmo/oml.c | 17 +++ 15 files changed, 340 insertions(+), 13 deletions(-) create mode 100644 include/osmo-bts/cbch.h create mode 100644 src/common/cbch.c hooks/post-receive -- Osmocom BTS-side code (Abis, scheduling, ...)

On the other hand, GSM 04.08/24.008, 4.7.3.1.4 in combination with 4.7.3.1.5, require the MS to retry the attachment procedure for cause codes above 15 instead of disabling GPRS. All of the mentioned GMM causes have codes above 15, so using a REJECT message including the cause code is a better choice. This way, the retry algorithm based on T3311 (15s, 5 times) and T3302 (default 12min) could be used. This patch modifies gprs_subscr_handle_gsup_auth_err and gprs_subscr_handle_gsup_upd_loc_err to proceed like when the access has beed denied, except that the corresponding subscriber's information fields are not cleared. This has been successfully tested which an iphone which enters a retry loop as it is being described in the specification.

Albeit all error return codes are negative, the semantics of the absolute value are not clearly defined. In addition, some return codes are not passed to the calling function.

This means, that an MS will not retry to attach even on temporary network errors. This patch changes these functions to use the GSUP error cause value to decide, whether to clear the corresponding subscriber fields, to just continue with the corresponding update function, or to log, ignore and not pass the cause to the MS in case the error is directly related to the GSUP protocol. The subscriber's error_cause field is updated, if the update function is going to be called. The error_cause fielt is reset on non-error GSUP messages.

On the other hand, GSM 04.08/24.008, 4.7.3.1.4 in combination with 4.7.3.1.5, require the MS to retry the attachment procedure for cause codes above 15 instead of disabling GPRS. All of the mentioned GMM causes have codes above 15, so using a REJECT message including the cause code is a better choice. This way, the retry algorithm based on T3311 (15s, 5 times) and T3302 (default 12min) could be used. This patch modifies gprs_subscr_handle_gsup_auth_err and gprs_subscr_handle_gsup_upd_loc_err to proceed like when the access has beed denied, except that the corresponding subscriber's information fields are not cleared. This has been successfully tested which an iphone which enters a retry loop as it is being described in the specification.

Albeit all error return codes are negative, the semantics of the absolute value are not clearly defined. In addition, some return codes are not passed to the calling function. This path changes these functions to always return a negated GMM cause value in case of errors. Return values of called parser functions are not longer ignored.

This means, that an MS will not retry to attach even on temporary network errors. This patch changes these functions to use the GSUP error cause value to decide, whether to clear the corresponding subscriber fields, to just continue with the corresponding update function, or to log, ignore and not pass the cause to the MS in case the error is directly related to the GSUP protocol.

These are then passed to the MS, unless gsm0408_gprs_access_cancelled is called with cause 0 (no error -> updateProcedure). Since gsm0408_gprs_access_denied uses GMM_CAUSE_GPRS_NOTALLOWED if the cause is not set, and the subscriber's error_cause is never set (and thus always 0), the SGSN's behaviour does not change with this patch.

This patch extends gsup_client_read_cb by a call to ipaccess_bts_handle_ccm. Only when the return code is 0, the message is processed further and checked for an OSMO/GSUP message. ID_GET messages are answered by a dummy description, where only the unit_name is set to 'SGSN'.

In either case, the application gets informed about the connection state via the updown_cb. The 'up' parameter is only set, if poll/select consider the socket as writable. This patch handles both cases equally and fully relies on the updown_cb to adjust the gsupc obejct state.

The MS has probably sent several Attach Requests while the connection was down and will continue doing so. Therefore these stored messages could be dropped. This patch clears the queue before re-connecting and also extends gprs_gsup_client_send to return immediately, when the connection is not established instead of calling ipa_client_conn_send. Sponsored-by: On-Waves ehf http://cgit.osmocom.org/openbsc/commit/?id=8f4fa5fc5f8225a5fb55fa2c4b12eace… commit 8f4fa5fc5f8225a5fb55fa2c4b12eace56b14df7 Author: Jacob Erlbeck <jerlbeck(a)sysmocom.de> Date: Thu Dec 18 15:00:29 2014 +0100 sgsn: Add automatic re-connect if the GSUP connection is down Currently the GSUP connection to a server is not restarted if the connection cannot be established or is terminated during operation. This commit adds a timer based connection mechanism, basically consisting of a timer callback that calls gsup_client_connect. The timer is eventually triggered (up == 0) or cleared (up != 0) by gsup_client_updown_cb. It adds calls to osmo_timer_del() to gsup_client_connect and gprs_gsup_client_destroy. The latter is now called instead of talloc_free in gprs_gsup_client_create on error to be on the safe side.

That is to say, the old revision is not a strict subset of the new revision. This situation occurs when you --force push a change and generate a repository containing something like this: * -- * -- B -- O -- O -- O (3552fc0ea816e0278737a9adf02bbebc0c9f3ea9) \ N -- N -- N (b392f1b1448b3eebf779457577fb439d533781c0) When this happens we assume that you've already had alert emails for all of the O revisions, and so we here report only the revisions in the N branch from the common base, B. Those revisions listed above that are new to this repository have not appeared on any other notification email; so we list those revisions in full, below. - Log ----------------------------------------------------------------- http://cgit.osmocom.org/openbsc/commit/?id=b392f1b1448b3eebf779457577fb439d… commit b392f1b1448b3eebf779457577fb439d533781c0 Author: Jacob Erlbeck <jerlbeck(a)sysmocom.de> Date: Tue Dec 23 14:24:16 2014 +0100 sgsn: Handle GSUP errors (WIP) Ticket: OW#????

This patch adds a timer based PING mechanism that regularly sends PING messages and forces a reconnect if a PONG message won't be received until the next PING message is scheduled. The current ping interval is 20s.

This means, that the client doesn't answer to PING and ID_GET and logs notices when receiving PONG or ID_ACK. At least the PING functionality (remotely originated PING) shall be supported. This patch extends gsup_client_read_cb by a call to ipaccess_bts_handle_ccm. Only when the return code is 0, the message is processed further and checked for an OSMO/GSUP message. ID_GET messages are answered by a dummy description, where only the unit_name is set to 'SGSN'.

In either case, the application gets informed about the connection state via the updown_cb. The 'up' parameter is only set, if poll/select consider the socket as writable. This patch handles both cases equally and fully relies on the updown_cb to adjust the gsupc obejct state.

The MS has probably sent several Attach Requests while the connection was down and will continue doing so. Therefore these stored messages could be dropped. This patch clears the queue before re-connecting and also extends gprs_gsup_client_send to return immediately, when the connection is not established instead of calling ipa_client_conn_send.

This commit adds a timer based connection mechanism, basically consisting of a timer callback that calls gsup_client_connect. The timer is eventually triggered (up == 0) or cleared (up != 0) by gsup_client_updown_cb. It adds calls to osmo_timer_del() to gsup_client_connect and gprs_gsup_client_destroy. The latter is now called instead of talloc_free in gprs_gsup_client_create on error to be on the safe side.

That is to say, the old revision is not a strict subset of the new revision. This situation occurs when you --force push a change and generate a repository containing something like this: * -- * -- B -- O -- O -- O (3fb6fbddfd6c7c524d9718953e11d1253c176c03) \ N -- N -- N (3552fc0ea816e0278737a9adf02bbebc0c9f3ea9) When this happens we assume that you've already had alert emails for all of the O revisions, and so we here report only the revisions in the N branch from the common base, B. Those revisions listed above that are new to this repository have not appeared on any other notification email; so we list those revisions in full, below. - Log ----------------------------------------------------------------- http://cgit.osmocom.org/openbsc/commit/?id=3552fc0ea816e0278737a9adf02bbebc… commit 3552fc0ea816e0278737a9adf02bbebc0c9f3ea9 Author: Jacob Erlbeck <jerlbeck(a)sysmocom.de> Date: Mon Jan 5 09:43:51 2015 +0100 sgsn: Fix VTY command error handling (Coverity) Currently the result of the osmo_hexparse function in update_subscr_insert_auth_triplet is not handled correctly.

The current ping interval is 20s.

This means, that the client doesn't answer to PING and ID_GET and logs notices when receiving PONG or ID_ACK. At least the PING functionality (remotely originated PING) shall be supported. This patch extends gsup_client_read_cb by a call to ipaccess_bts_handle_ccm. Only when the return code is 0, the message is processed further and checked for an OSMO/GSUP message. ID_GET messages are answered by a dummy description, where only the unit_name is set to 'SGSN'.

In either case, the application gets informed about the connection state via the updown_cb. The 'up' parameter is only set, if poll/select consider the socket as writable. This patch handles both cases equally and fully relies on the updown_cb to adjust the gsupc obejct state.

The MS has probably sent several Attach Requests while the connection was down and will continue doing so. Therefore these stored messages could be dropped. This patch clears the queue before re-connecting and also extends gprs_gsup_client_send to return immediately, when the connection is not established instead of calling ipa_client_conn_send.

This commit adds a timer based connection mechanism, basically consisting of a timer callback that calls gsup_client_connect. The timer is eventually triggered (up == 0) or cleared (up != 0) by gsup_client_updown_cb. It adds calls to osmo_timer_del() to gsup_client_connect and gprs_gsup_client_destroy. The latter is now called instead of talloc_free in gprs_gsup_client_create on error to be on the safe side.

It was generated because a ref change was pushed to the repository containing the project "The OpenBSC GSM Base Station Controller (+MSC/HLR/SGSN)".

A call to a subscriber will now only proceed if active_cc_transactions is either 0, or CW has been provisioned and activated for that subscriber, otherwise the caller will receive a "busy" signal. http://cgit.osmocom.org/openbsc/commit/?id=33bc1716f435e81d837268cbb04ddf74… commit 33bc1716f435e81d837268cbb04ddf7487f14a32 Author: Tobias Engel <tobias(a)ccc.de> Date: Thu Mar 22 15:07:29 2012 +0100 SS: Supplementary Services (de)activation and interrogation These patches enhance the Supplementary Service (SS) processing from only being able to handle USSD to other SS, specifically activation, deactivation and interrogation of those SS. Registration is not yet implemented. The HLR db now includes a table SS_Status which contains fields for the SS code (GSM 09.02 17.7.5), basic service code (17.7.9 and 17.7.10) and SS status bits (17.7.4) and references the subscriber. db.c supports interrogating and setting the SS status with the functions db_ss_interrogate_status and db_ss_set_status. No automatic provisioning takes place. To do so, a record has to be added to the db referencing the subscriber and containing the desired SS code, BS code and having the 'P' bit in the SS status set to one. All occurrences of "ussd" have been replaced with "ss" where the corresponding file/function/variable deals not exclusively with USSD requests. ussd.c and ussd.h have been renamed to ss.c and ss.h. gsm0480_send_ss_return_result has been added to gsm_04_80.c. It takes a msgb as an argument which has to already contain the ASN.1 formatted Return Result minus the operation code and invoke id. change_ss_activation and interrogate_ss have been added to ss.c (formerly ussd.c). Currently, (de)activation and interrogation of SS will always be handled as if it was requested for the Telephony teleservice, no matter what was requested by the subscriber. Also, sending a Return Error has not been implemented yet (Reject is used instead). ----------------------------------------------------------------------- hooks/post-receive -- The OpenBSC GSM Base Station Controller (+MSC/HLR/SGSN)

The only reason to keep it out of master was the fact that the UDP data structures it sends are non-portable, so you can only run it reliably on localhost or between identical systems (hardware/compiler/os). As this hasn't been fixed in the past >= 2 years, I am merging the code now anyway. We can still introduce a portable protocol by increasing the protocol version at a later point. There are two options: a) we make 'struct gsm_meas_rep' portable. This requires an ABI change with libosmocore, as it contains struct gsm_meas_rep_unidir :( b) we introduce a completely separate wire format with corresponding encoding and decoding functions. http://cgit.osmocom.org/openbsc/commit/?id=8db0788896221633dbe0660d08ca03e9… commit 8db0788896221633dbe0660d08ca03e9dcfec2b2 Author: Harald Welte <laforge(a)gnumonks.org> Date: Thu Jan 1 13:06:48 2015 +0100 meas_feed.c: Fix compiler warning http://cgit.osmocom.org/openbsc/commit/?id=dfbc42c261b438271487822f0ccd687f… commit dfbc42c261b438271487822f0ccd687fda84129f Author: Harald Welte <laforge(a)gnumonks.org> Date: Thu Nov 15 12:29:15 2012 +0100 meas_feed: add osmo-meas-udp2db for realtime feed into database This tool can save the meas_feed messages from UDP port 8888 directly to a sqlite3 database for further analysis. http://cgit.osmocom.org/openbsc/commit/?id=dc9b4e9ebf64e0227c85ebbb870254a1… commit dc9b4e9ebf64e0227c85ebbb870254a1de6058d4 Author: Harald Welte <laforge(a)gnumonks.org> Date: Thu Nov 15 00:12:56 2012 +0100 meas_feed: Add tool to read meas_feed PCAP and write it to sqlite3 In fact, the DB write code has been split out so we could later also have a binary that would listen to realtime meas_feed packets and stuff them into a database without any intermediate PCAP step. The database schema contains a couple of convenience wrapper views, most notably the "overview" view. http://cgit.osmocom.org/openbsc/commit/?id=7465e4c2e19f25bad3c92288e323d4d0… commit 7465e4c2e19f25bad3c92288e323d4d0d9f7baf1 Author: Harald Welte <laforge(a)gnumonks.org> Date: Tue Nov 13 07:06:54 2012 +0100 build meas_vis only if libcdk is available http://cgit.osmocom.org/openbsc/commit/?id=61c9156a744f48493aea3f7ff175a3ed… commit 61c9156a744f48493aea3f7ff175a3ed56d154cd Author: Harald Welte <laforge(a)gnumonks.org> Date: Sun Nov 11 12:57:05 2012 +0100 meas_vis: Add header and print TA + TO values http://cgit.osmocom.org/openbsc/commit/?id=98ba6359a16ce6555dee87ccde09ba6e… commit 98ba6359a16ce6555dee87ccde09ba6ef46bc858 Author: Harald Welte <laforge(a)gnumonks.org> Date: Sun Nov 11 12:33:30 2012 +0100 meas_vis: assign bar colors depending on level, display RxQual http://cgit.osmocom.org/openbsc/commit/?id=b4771a6871efb3cf12b371aedc575912… commit b4771a6871efb3cf12b371aedc575912984ca528 Author: Harald Welte <laforge(a)gnumonks.org> Date: Sun Nov 11 10:58:51 2012 +0100 Initial support for export + curses-visualization of measurements This extends osmo_nitb to offer a UDP feed of real-time measurement reports, which can be used by (a variety of) external tools for visualization or other processing. We also add a small ncurses based tool (meas_vis) which shows a baragraph display of the last few mobile stations that were active, indicating their uplink/downlink receive level and quality. <WARNING> This sends non-portable structures like gsm_meas_rep over UDP and assumes the receiver has identical alignment and endianness! Before this feature is merged, it either needs to be converted to a unix domain socket (but they don't do multicast, which would be nice) or the wire format needs to change into something portable with defined alignment and encoding </WARNING> ----------------------------------------------------------------------- Summary of changes: openbsc/configure.ac | 4 + openbsc/include/openbsc/Makefile.am | 2 +- openbsc/include/openbsc/meas_feed.h | 29 +++ openbsc/src/libmsc/Makefile.am | 6 +- openbsc/src/libmsc/meas_feed.c | 158 +++++++++++++++ openbsc/src/libmsc/meas_feed.h | 12 ++ openbsc/src/libmsc/vty_interface_layer3.c | 35 ++++ openbsc/src/utils/Makefile.am | 20 +- openbsc/src/utils/meas_db.c | 323 ++++++++++++++++++++++++++++++ openbsc/src/utils/meas_db.h | 17 ++ openbsc/src/utils/meas_pcap2db.c | 141 +++++++++++++ openbsc/src/utils/meas_udp2db.c | 123 ++++++++++++ openbsc/src/utils/meas_vis.c | 306 ++++++++++++++++++++++++++++ 13 files changed, 1172 insertions(+), 4 deletions(-) create mode 100644 openbsc/include/openbsc/meas_feed.h create mode 100644 openbsc/src/libmsc/meas_feed.c create mode 100644 openbsc/src/libmsc/meas_feed.h create mode 100644 openbsc/src/utils/meas_db.c create mode 100644 openbsc/src/utils/meas_db.h create mode 100644 openbsc/src/utils/meas_pcap2db.c create mode 100644 openbsc/src/utils/meas_udp2db.c create mode 100644 openbsc/src/utils/meas_vis.c hooks/post-receive -- The OpenBSC GSM Base Station Controller (+MSC/HLR/SGSN)

However, ever since, PCHAN types (channel combinations) are configured by OML in a certain way, and we only allocate LCHANs inside PCHANs of a matching type. There should be no PCHANs with type GSM_PCHAN_NONE, unless those that you don't want to use for administraive reasons or the like. ----------------------------------------------------------------------- Summary of changes: openbsc/include/openbsc/chan_alloc.h | 11 ---- openbsc/include/openbsc/rest_octets.h | 2 +- openbsc/src/libbsc/chan_alloc.c | 107 +------------------------------- openbsc/src/libbsc/rest_octets.c | 4 +- openbsc/src/libbsc/system_information.c | 2 +- 5 files changed, 5 insertions(+), 121 deletions(-) hooks/post-receive -- The OpenBSC GSM Base Station Controller (+MSC/HLR/SGSN)
