* Use existing function for TLLI encodingMax2018-01-082-15/+5
| | | | | | Use bssgp_msgb_tlli_put() instead of copy-pasted code. Change-Id: I06d60566a19dcae701f8648c19fbd8db6d586f77
* Add function to properly encode RAIMax2018-01-083-26/+22
| | | | | | | | | | | | | Add gsm48_encode_ra() which takes appropriate struct as [out] parameter instead of generic buffer. Using uint8_t buffer instead of proper struct type prooved to be error-prone - see Coverity CID57877, CID57876. Old gsm48_construct_ra() is made into tiny wrapper around new function. The test output is adjusted because of the change in function return value which was constant and hence ignored anyway. Related: OS#1640 Change-Id: I31f9605277f4945f207c2c44ff82e62399f8db74
* gprs_bssgp: bssgp_fc_in(): fix mem leak on queue overflowNeels Hofmeyr2017-11-201-1/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | All successful and all error code paths of bssgp_fc_in() free the msgb, except the code path calling fc_enqueue() when the msg is dropped (due to queue being full, or failure to allocate). Callers could theoretically catch the -ENOSPC return value and discard the msgb. However, in other code paths, a callback's return value is returned, which is expected to free the msgb, so such callback would have to never return -ENOSPC when it freed the msgb. Much simpler semantics would be to free the msgb in every code path, no matter which kind of error occurred. Who is currently calling bssgp_fc_in and how do they handle the return value? - bssgp_fc_test.c ignores the return value (and hits a mem leak aka sanitizer build failure if the queue is full). - fc_timer_cb() ignores the return value. - bssgp_tx_dl_ud() returns the bssgp_fc_in() rc. - which is returned by a cascade of functions leading up to being returned, for example, by gprs_llgmm_reset(), which is usually called with ignored return code. At this point it is already fairly clear that bssgp_fc_in() should always free the msgb, since the callers don't seem to distinguish even between error or success, let alone between -ENOSPC or other errors. bssgp_fc_test: assert that no msgbs remain unfreed after the tests. Adjust expected results. Helps fix sanitizer build on debian 9. Change-Id: I00c62a104baeaad6a85883c380259c469aebf0df

* gb: optionally allow nsip packets only from a specific hostPhilipp Maier2017-10-241-3/+25
| | | | | | | | | | | | | | When listening for nsip connections is enabled, then every remote host may send packets. This is useful for an SGSN that serves multiple PCUs, but contraproductive for a PCU that awaits packets from a single SGSN. Add struct members remote_ip, and remote_port to struct gprs_ns_inst, when set, then the listening end uses connect() to ensure that only the expected host may send packets.

* vty: install 'exit', 'end',... commands on *all* nodesNeels Hofmeyr2017-09-272-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In many callers of the VTY API, we are lacking the vty_install_default() step at certain node levels. This creates nodes that lack the 'exit' command, and hence the only way to exit such a node is to restart the telnet session. Historically, the VTY looked for missing commands on the immediate parent node, and hence possibly found the parent's 'exit' command when the local node was missing it. That is why we so far did not notice the missing default commands. Furthermore, some callers call install_default() instead of vty_install_default(). Only vty_install_default() also includes the 'exit' and 'end' commands. There is no reason why there are two sets of default commands. To end this confusion, to catch all missing 'exit' commands and to prevent this from re-appearing in the future, simply *always* install all default commands implicitly when calling install_node(). In cmd_init(), there are some top-level nodes that apparently do not want the default commands installed. Keep those the way they are, by changing the invocation to new install_node_bare() ({VIEW,AUTH,AUTH_ENABLE}_NODE). Make both install_default() and vty_install_default() no-ops so that users of the API may still call them without harm. Do not yet deprecate yet, which follows in Icf5d83f641e838cebcccc635a043e94ba352abff. Drop all invocations to these two functions found in libosmocore.

* gb: drop special vty exit commands, use vty_install_default()Neels Hofmeyr2017-09-274-43/+2
| | | | | | | | | | | | | | | L_NS_NODE and L_BSSGP_NODE had specialized 'exit' and 'end' vty commands, but all they do is return to the CONFIG and ENABLE_NODEs like the default 'exit' and 'end' commands. Drop them and use the default 'exit' and 'end' cmds. Examining BSSGP and NS node behavior in osmo-sgsn exhibited identical list and exit/end behavior before and after this patch. Prepares for an upcoming commit incorporating vty_install_default() into install_node(), see I5021c64a787b63314e0f2f1cba0b8fc7bff4f09b: this patch changes to the default commands, the upcoming change implies them.

According to 3GPP TS 48.018 §8.4 "after performing the BVC Reset procedure all affected BVCs are assumed to be unblocked at the SGSN" so there's no need in any special handling.

| | | | | | | | | | | | | | | My recent logging patch was merged to master a bit too soon. Accomodate the request for naming that matches the general "LOG" prefix instead of "LOGGING". libosmocore will not be backwards-compatible with the few commits from change-id I5c343630020f4b108099696fd96c2111614c8067 up to this one.

* logging: centrally define ctx and filter indexesNeels Hofmeyr2017-02-226-39/+33
| | | | | | | | | | | | | | | | | | | | | | | It is too easy for calling code to use the same filter and context indexes for different filters and structs. For example, openbsc's IMSI filter and libgb's GPRS_BVC filter both fall on index 1 even though there are plenty more indexes to choose from. To alleviate this, have one central definition here, sort of like ports.h does for VTY and CTRL port numbers. Add static asserts to make sure the indexes fit in the available array and bit mask space. Calling code like openbsc.git and osmo-pcu need adjustments and/or should move to using these enum values instead of their local definitions. Taking this opportunity to also prepare for a split of struct gsm_subscriber in openbsc into bsc_subsciber and vlr_subscriber with appropriate separate filter index constants for both subscriber types. Include previous LOG_FILTER_ALL in the LOGGING_FILTER_* enum, and replace its use by (1 << LOGGING_FILTER_ALL). Change-Id: I5c343630020f4b108099696fd96c2111614c8067

* ns: Force a defined state when sending NS RESETJacob Erlbeck2015-12-171-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | Currently the state is assumed to remain the same while the reset procedure is active. While this works correctly in general, a single unexpected BLOCK_ACK or UNBLOCK_ACK can change the state but will not stop the reset procedure. The leads to repeated RESET messages, where the corresponding RESET_ACK is ignored. This is a stable state which can only be left by manual intervention or by reception of a RESET message from the peer. This commit changes the RESET timeout handler to set the state to BLOCKED/RESET when sending the new NS RESET message. Note that this should ensure a clean restart even if the state has been screwed up. It does not fix the handling of BLOCK_ACK or UNBLOCK_ACK in abnormal cases.

* gprs-ns/stats: When the NSVCI is updated, update the stats counterHolger Hans Peter Freyther2015-11-041-0/+2
| | | | | | | | | | | The NS object is created with an unknown identity and only after the reset procedure has progressed (completed?) we know the real ID for this peer. Before nobody has looked at the idx values (this could have been seen with the CTRL interface) but with statsd the wrong NSVCI becomes obvious. Add routines to update the idx and I don't know if the change of idx is causing any issues but we will find that out soon.
* ns/stats: Fix class_id of "NSVC Peer Statistics" rate_ctr groupJacob Erlbeck2015-08-221-0/+1
| | | | | | | | | Currently the class_id is not set which effectively puts these groups into the 'subscriber' class. This commit adds the missing initialisation value. Sponsored-by: On-Waves ehf
