2017-10-27Doxugen: s/libosmo-sccp/libosmo-sigtran/gHarald Welte2-9/+9
The Doxygen annotation we have in this library, and which the Doxyfile generates is actually for the shared libosmo-sigtran, and not for the legacy libosmo-sccp. Let's correct that mistake. Change-Id: Id591695f9ac9eba53259558c657df834c331e5fa

2017-10-27implement unit tests for osmo_sccp_addr_{parse,encode}()Harald Welte6-2/+260
The recent bug with chopped-off point codes in SCCP Address handling has shown that this code could need proper test cases. This patch adds a testsuite for SCCP address encoding and decoding. Related: OS#2441 Change-Id: I612352736ab33462ca0dd97798a2c437eadccb86
2017-10-27osmo_sccp_addr_encode(): Catch some more errors and log themHarald Welte1-0/+10
Log errors in case the user provides global title indicators or nature-of-address indicators that exceed the permitted value range Change-Id: I493b7810bdc58e448f496565ded36f9dce2c1226
2017-10-27osmo_sccp_addr_encode(): Fix truncation of point codesHarald Welte1-1/+1
In osmo_sccp_addr_encode(), we accidentially truncated all point codes to 10 bits, where in reality we should have truncated them to 14 bits: One 'f' was missing in the bit-mask. Closes: OS#2441 Change-Id: Iad67b674b5b5fd41996aa898a131e98900842dd8

2017-10-26sccp_scrc: fix Network Indicator in SIO compositionNeels Hofmeyr1-1/+1
Since the NI is in bits DC, not BA, it needs to be shifted by 6, not 4, to end up in the two most significant bits. Also, NI is two bits wide, hence & 0x3. (The m3ua.c side of this is already correct.) See ITU-T Recommendation Q.704 (07/96), 14.2 "Service information octet". Before this patch, NI was always sent as 00 == International regardless of the VTY configuration. This patch was verified to work by a wireshark trace of osmo-bsc connecting to osmo-msc, showing the NI decoded as configured by an osmo-bsc.cfg file in the BSSMAP Reset message MTP 3 / Protocol data. Change-Id: I7bb4eb6518a1e0d74313bda776d2a6acd0b02e1b

2017-10-04Makefile.am: Link libosmo-sigtran against libvtyHarald Welte1-2/+4
libosmo-sigtran is using symbols from libosmo-vty, so make sure that we explicitly link against libosmo-vty to ensure the dependency shows up in `ldd` of the library. Change-Id: I4d96612a0df5a1232ed8fe280c5d592f462ef7b1

2017-09-14simple client: prevent overwriting asp settingsPhilipp Maier1-13/+28
If the user does not create an AS, but creates an ASP with a name that is equal to the default name, then the simple client detects that and trys to use this ASP. However, unfortunately it then overwrites the settings of the ASP with the default settings. If the detected ASP is not created by the simple client, use it, but preseve the settings of that ASP. Change-Id: I53d73059f804c3bbea6cb43dc73ad49a753b3b15
2017-09-11vty: add 'asp' / 'local-ip' commandNeels Hofmeyr1-0/+13
We can set the ASP's remote IP (i.e. where to reach osmo-stp), but so far the only way to specify the local IP address to bind to can only be set from C code (e.g. the simple client). Allow setting the local address via VTY. For example, this is desired for the osmo-gsm-tester, to not use arbitrary IP addresses. Change-Id: I3f71897dfacafcf3126e51894d6ca756b02dcd7d
2017-09-03sccp_sap.h: Fix SSN for BSSAP and BSSAP-LEHarald Welte3-5/+7

2017-08-31osmo-stp: Fix process termination on SIGINT+SIGTERMHarald Welte1-1/+4
In commit eed8c1bfae1d151e135b574d83ed295d36ad8b44 we introduced some singal handling code for (among others) SIGINT and SIGTERM. This code causes the process to hang rather than terminate, as it only dispatches a signal that nobody handles yet in libosmo-sccp. Until a proper implementation is made, let's terminate the process as expected. Change-Id: Iff79c8ac0b347660333912c9258073a013ea799b

2017-08-24sccp: again fix handling of default IP addresses in osmo_sccp_simple_client()Philipp Maier1-4/+2
The previous fix (I312caf9d54cedb02034e4ef88fdd2e6ad9ca1c34) caused the default addresses to be discarded. Actually talloc_strdup() the default addresses to use them if not NULL. Change-Id: Ic8563ab272d5256a1b8ceefd5fee37da61e1bd26
2017-08-23osmo_ss7_vty: fix 'as' / 'routing-key' commandNeels Hofmeyr1-31/+58
The VTY definition for this command is flawed and breaks osmo-msc VTY tests. The small problem is a stray '}' in the definition, the bigger problem is that square brackets indicating optional arguments must not enclose more than one argument. Split up the command in several separate definitions with si arg, with ssn arg, with both, and with neither. If si and/or ssn are not passed, set them to zero. See https://lists.osmocom.org/pipermail/openbsc/2017-August/011026.html "optional vty items are stricter than expected" Change-Id: Idc68bfae5457960a9eae5d9648586d6ce719ad68

2017-08-15Fix SCCP client crash on xUA server (STP) disconnectHarald Welte1-1/+0
When the server (STP) disappears from a live SCCP client, then the xUA default layer manager receives LM_E_SCTP_DISC_IND, which is traversing retart_asp(). In there, we first terminate the current instance of the layer manager FSM, and then re-initialize the ASP to use the default layer manager using osmo_ss7_asp_use_default_lm(). However, osmo_ss7_asp_use_default_lm() uses the presence of an asp->lm_priv pointer as a sign that the old layer manager is still running and attempts to terminate it - despite being terminated just before in restart_as(). So let's simply remove the termination from restart_asp(), and leave it to osmo_ss7_asp_use_default_lm(). Fixes: OS#2402 Change-Id: I062d3af17539de864b56d079fe9b8d76ad99cf1e
2017-08-15vty: fix (null) string in vty configPhilipp Maier1-1/+2
The asp->cfg.remote.host is allowed to be NULL in cases where the localhost is used. Check if asp->cfg.remote.host is NULL when writing the config file and omit it when it is set to NULL. Change-Id: I18f79cc4d4f1db8f2858e8e95098c5821d50594f
2017-08-11sccp: fixup for osmo_sccp_get_ss7()Philipp Maier2-2/+7
osmo_sccp_get_ss7() has the risk of a nullpointer dereference, when sccp is NULL. Return NULL when the sccp instance is NULL. Add doxygen comment Change-Id: I84d484e4441fd37443fff8c67e17df8fb15d5b2e
2017-08-11sccp: function to get sccp instance from sccp userPhilipp Maier2-0/+11
It is currently impossible to find out which SCCP instance handles a particular user. Introduce function to lookup the SCCP instance from a given SCCP user. Change-Id: I9562c4f1d00e2ebb3252c5dea598b643aa393719
2017-08-11sccp: make osmo_sccp_addr_name() availablePhilipp Maier1-0/+1
osmo_sccp_addr_name() is not listed in any header file. Add osmo_sccp_addr_name() to sccp_helpers.h in order to make it available. Change-Id: I092dd55948faeeff78f28f7d50c5b84b9e69ef24
2017-08-11sccp: add doxgen comments for osmo_sccp_simple_client()Philipp Maier1-0/+32

2017-08-11sccp: check for valid point code in osmo_sccp_simple_client()Philipp Maier1-6/+10
The point-code is not checked in the beginning, only the ASP checks the point code at a very late stage and fails in case an invalid point-code is detected. Remove the check in the ASP creation. Add a new check after the SS7 initalization that checks the point-code. If none is set, the default point-code will be used. Change-Id: I334d90e769bd9952f67c51b12a945f22bd268fa8
2017-08-11sccp: fix handling of default IP addresses in osmo_sccp_simple_client()Philipp Maier1-4/+4
When the default IP addresses (remote or local) the respective struct value should be set to NULL. Fix wrong ?:-notation. Change-Id: I312caf9d54cedb02034e4ef88fdd2e6ad9ca1c34
2017-08-10sccp: prefix default parameters of osmo_sccp_simple_client()Philipp Maier2-27/+37
The simple client takes certain parameters (pc, ip and port numbers) which serve as a fallback default in case the user did not configure any suitable parameters via the VTY. Prefix all default variables with default_ to make the purpose clear to the API user Change-Id: Id9e697e8b198e4f58a79e59aaf2e649e84a3eb63

2017-08-09vty: hide SG commands when running as ASPPhilipp Maier1-5/+13
The SG (signal gateway) requires an extra set of VTY commands in order to be fully configurable. These VTY commands do not make sense in a situation where libosmo-sccp is used to implement an ASP (application server process). Detect in which role libosmo-sccp is used by which of the VTY initalization functions are called: osmo_ss7_vty_init_asp() ==> ASP osmo_ss7_vty_init_sg() ==> SG Prevent writing back of SG specific configuration when in running as ASP. Only write back the full parameter set when running as SG. Change-Id: I707bcd790f4c6d0f618e41163b51d2179ea3aeaf
2017-08-09sccp: fix creating of the default route in simple clientPhilipp Maier1-3/+7
The simple client (osmo_sccp_simple_client_on_ss7_id() and osmo_sccp_simple_client) does not create a default route if the user has already created an AS via VTY. Check the presence of a default route independently of the AS. If no default route exists, create one. Change-Id: I7516fa5509bade4ba10e9d8eaa3e46cfe3696b3a

2017-08-09add osmo_sccp_addr_name() and three value_string[]sNeels Hofmeyr3-0/+84
osmo_sccp_addr_dump() just prints the raw values. In osmo_sccp_addr_name(), use osmo_ss7_pointcode_print() and newly added RI, SSN and GT value_string[] to print more human readable log output. Change-Id: Ie1aedd7894acd69ddc887cd65a8a0df4b888838c

2017-08-09consistency: use OSMO_SS7_PC_INVALID for osmo_sccp_userNeels Hofmeyr4-21/+16
A previous patch added ss7_instance primary_pc validity checks by means of OSMO_SS7_PC_INVALID. To be consistent, also adjust sccp_user accordingly. (see I7f0f0c89b7335d9da24161bfac8234be214ca00c) Remove the osmo_sccp_user's pc_valid field, replaced by pc=OSMO_SS7_PC_INVALID. Adjust all code paths. Simplify some log printing, using the fact that osmo_ss7_pointcode_print() now outputs "(no PC)" for unset point codes. Change-Id: I8684c9b559712072c772012890bbf7efa7c8eb35
2017-08-09ensure valid primary_pc in osmo_ss7_instanceNeels Hofmeyr5-6/+19
Initialize osmo_ss7_instance.cfg.primary_pc = OSMO_SS7_PC_INVALID. Adjust all code paths using primary_pc to ensure it is indeed valid. Rationale: It looks like we are going to use the primary point-code of an SS7 instance to derive a local SCCP address, e.g. for osmo-bsc and osmo-hnbgw. cs7-instance 1 point-code 1.2.3 ! sets osmo_ss7_instance.primary_pc = 1.2.3 sccp-address msc point-code 0.0.1 routing-indicator PC hnb iucs remote-addr msc ! derives cs7 instance 1 and local pc 1.2.3 If 'point-code 1.2.3' is omitted, this becomes '0.0.0' without the user noticing, and this happens for each client that omits it. I would like to barf when no local PC is set. Change-Id: I7f0f0c89b7335d9da24161bfac8234be214ca00c
2017-08-09add OSMO_SS7_PC_INVALID, add osmo_ss7_pc_is_valid()Neels Hofmeyr2-3/+17
Introduce OSMO_SS7_PC_INVALID to mark an unset point code. Add static osmo_ss7_pc_is_valid() (name matches schema of osmo_ss7_pc_is_local()). In osmo_ss7_pointcode_print(), return "(no PC)" if !osmo_ss7_pc_is_valid(), for convenient printing of any PC state. Subsequent patches will use this for osmo_ss7_instance (I7f0f0c89b7335d9da24161bfac8234be214ca00c) as well as osmo_sccp_user (I8684c9b559712072c772012890bbf7efa7c8eb35). Rationale: Currently, in osmo_ss7_vty.c we had "if (inst->cfg.primary_pc)" suggesting 0 is invalid, but in struct osmo_sccp_user we have flag pc_valid suggesting 0 is indeed valid. All known point code formats are <= 24bit, so we can easily use 0xffffffff as indicator for an unset PC, which removes the need to remember to set a second field for validity and keeps the structs nice and lean.

2017-08-07osmo_ss7_vty_init: ensure a talloc ctx is set by userNeels Hofmeyr4-15/+11
Drop the separate osmo_ss7_set_vty_alloc_ctx() because we are likely to forget calling it. Instead, incorporate into osmo_ss7_vty_init_*() with a new ctx arg, and set the static context var in vty_init_shared(). Change-Id: Id4e7f47979001f7856b0b3665c9e94982e75e490

2017-08-01sccp: derive local address from given sccp instancePhilipp Maier2-0/+26
The most important parts of an SCCP address are the routing indicator and the pointcode. The latter one is always available via the SS7 instance, so a basic local address can be derived from there. Add function osmo_sccp_local_addr_by_instance() to derive a basic local SCCP address from a given SCCP instance Change-Id: I371dc9132871aad3d8321ea13cf9fd69d76eff8f
