Harald Welte 5de728564c Rename osmo_fsm to avoid illegal space in name + more meaningful name
A FSM doesn't need "FSM" in its name, as it is obvious that it is a
FSM.  Also, having two that are called RESET is confusing, so let's
try to come up with better names.

Also, after Change-Id I9ef59432f43a3cdb94e4cbb0c44ac3f9b2aac0f2 in
libosmocore, we now enforce that no FSM identifiers contain spaces
or other illegal characters.

The library code for rate counter initialization, which is called

log something (particularly after Change-Id
Ifc6ac824f5dae9a848bb4a5d067c64a69eb40b56 in libosmocore), so the
logging framework must be initialized before.

(gdb) print lchan
$2 = (const struct gsm_lchan *) 0x0

Possible scenario in which this crash can appear:
1- gsm0808_assign_req() calls handle_new_assignment() which sends an CHAN
ACTIVATE msg and arms T10 timer.
2- ACTIVATE ACK is received (handle_chan_ack), which calls
gsm48_send_rr_ass_cmd() which sends an ASSIGNMENT CMD, and doesn't
disable/modify T10 timer.
3- T10 timeout is triggered (assignment_t10_timeout()), which sets
conn->secondary_lchan = NULL
4- Immediately after, the ASSIGNMENT FAILURE message (which might have been
already queued) is processed in handle_ass_fail, and then the crash occurs.

This race condition is not an issue for handle_ass_compl() path because there's
this check there which would trigger most probably if secondary_lchan is NULL:
"if (conn->secondary_lchan != msg->lchan)"

Neels Hofmeyr ff20215db2 add ';' after OSMO_ASSERT()
Currently, OSMO_ASSERT() is defined such that it ends in a semicolon, hence an
added ';' is redundant. However, the usual way this kind of macro should be
defined is

  #define OSMO_ASSERT(x) do { ... } while(0)

so that the compiler requires a trailing semicolon.

To prepare for such a change possibly coming up in libosmocore, add ';' to all
OSMO_ASSERT() users.

Pau Espin 56d96da8ef libmsc: Fix wrong handling of user_message_reference parameter
libsmpp34 already converts received TLV integer values to native
endianess in libsmpp34_(un)pack.

Converting them again at receive time swaps the 2 bytes of
user_message_reference, then using a wrong value. As GSM03.40 spec
uses only 1 byte for the id, then only the high byte of the initial
value is used and eventually sent back to the ESME. Again, at that time,
htons() is not needed because libsmpp34 already handles that part.

See OS-#2429 for more details.

Harald Welte e4dd94d080 Fix gsm_pchan2chan_nr() to use RSL_CHAN_OSMO_PDCH
When converting from GSM_PCHAN_PDCH, we should generate
a RSL channel number IE with the osmocom extension
RSL_CHAN_OSMO_PDCH rather than claiming it is a regular
TCH/F channel.

This is important as this function is used by
osmo-bts, too - and it decides which channel number IE is
put in the GSMTAP header for both GSMTAP tracing as well
as the GSMTAP based osmo-bts-virtual.

In order to avoid any unintended effect on libbsc,
we make sure to modify rsl_ipacc_pdch_activate() to
always use GSM_PCHAN_TCH_F in related RSL message.

Pau Espin a13c07e71f mgcp: Fix uplink activation of Osmux stream
Commit 5754206379 introduced
OSMUX_STATE_NEGOTIATING to fix a race condition present in osmo-bsc_nat.
However, after this change osmo-bsc_mgcp cannot switch to
OSMUX_STATE_ACTIVATING anymore, which means during osmux_send_dummy time
it won't call osmux_enable_endpoint(), which in turn won't set endp type
to MGCP_OSMUX_BSC.

If MGCP_OSMUX_BSC is not set, uplink streams are sent using regular RTP
instead of Osmux not matter it is enabled in config or not.

Ivan Kluchnikov 04fc75f856 handover_logic: set correct link to bts for subscriber_connection in case of moving this connection to another bts
In case of successful completion of handover gsm_subscriber_connection could be moved from one bts to another,
so connection link to bts should be replaced by link to bts, which owns new_lchan.
This bug was detected, because conn->bts->nr is used in call control log messages
and wrong number of bts was observed in these messages after handover.

Alexander Chemeris 0796a6c0fc libcommon: Fix log output for bts>0.
Fixes regression probably introduced in c696cc28.

For bts>0 logging doesn't show bts number correctly when printing lchan
identification string - it will always show it as "bts=0". The reason for
this is that the identification string is cached before bts->nr value is
set to a proper value.

This patch sets bts->nr as part of the first step of the bts structure
initialization, before caching happens thus making sure the cached
identification string is cached with the correct values.

Pablo Neira Ayuso a644ee92be libmsc: update database to accomodate SMS status-report fields
SMPP DELIVER_SM messages with esm_class = Delivery Receipt need to send
this message reference (that the mobile phone allocates) to the ESME.
Thus, the ESME propagates it via SUBMIT_SM with esm_class = Delivery
Acknoledgment so that the SMSC sends the GSM 03.40 status-report to the
origin including this. Given this field is useful for status-reports, we
need to store it in the HLR database.

Moreover, we need a new field that specifies if the entry represents a
SMS status-report, to do the right handling from the gsm411_send_sms() -
such new handling comes in a follow up patch entitled "libmsc: handle
delivery ack via SMPP SUBMIT SM / send GSM 03.40 status report".

This patch includes the migration routines to the new database schema
revision 5, it's quite a bit of dbi boilerplate code - copied-pasted and
adapted.

This patch implements "Appendix B. Delivery Receipt Format" as specified
in the SMPP 3.4 specs. This string is conveyed in the SMS message as
data, and it is only meaningful to the ESME, for logging purposes. The
"submit date" and "done date" are not yet set, and other fields are just
sent with dummy values, so they are left to be finished as future work.

The new SMPP TLV tag TLVID_user_message_reference is added to the SMPP
messages inconditionally now since this information is required by
delivery-reports to associate the status-report with the original SMS.

The following branch:

	if (!rc && !gsms->receiver)
		rc = GSM411_RP_CAUSE_MO_NUM_UNASSIGNED;

at the end of sms_route_mt_sms() always evaluates false.

Just a bit before, in such function, we have this:

        if (!gsms->receiver) {
                ...
 #ifdef BUILD_SMPP
                ...
 #else
                ...
 #endif
                return rc;
        }

So, if there is no receiver, we just stop running code and return the RP
cause via the rc variable. Same applies to the smpp_first check under
the BUILD_SMPP ifdef (that I have removed in this snippet to keep this
commit message small).

Harald Welte a0d324b3d0 GSM timers: User reasonable defaults; don't save if equal default
A number of the GSM timers (including T3109) had no reasonable
default values if not specified in the VTY / config file.  Together
with unconditional writing to the config file, this created
config files with a persistent setting for important timers as '0'.

To make things worse, many of our example cofig files suffered from the
same problem.

Let's avoid this from happening by
* having reasonable defaults if nothing specified in the config file
* conditionally savingg timers only if they differ from default
* reject any timer values that state zero during start-up (see previous
  commit)

Harald Welte 17905c6c96 gtphob: check for missing result of rate_ctr_group_alloc()
In case the counter group allocation fails, we must handle this
gracefully and fail the allocation of the parent object, too.

The recent change (Id I7dad4a4d52fe05f6b990359841b4408df5990e21) seems
to have missed one instance, so let's follow-up.

Harald Welte 244e6c7913 gsm_bts_trx_set_system_infos(): Disable non-existing SI
If we previously had a given SI present/active, we must send a
zero-length BCCH FILLING for that SI type to the BTS to stop it from
further transmitting this SI.

Harald Welte 4c5a037ffc RSL: Allow disabling of BCCH/SACCH filling for given SI type
If we want to instruct the BTS to stop sending a given SI, we must be
able to send the respective BCCH INFO / SACCH FILLING with a header but
without any L3 data IE.  This patch enables the related functions to do
this whenever their data argument points to NULL.

Harald Welte 243d768d7d Fix regression causing loss of static system-information messages
In commit 8b1a2f8cd7 we started to
initialize bts->si_valid to 0.  This means we are skipping the manually
configured static system information.

Instead, we have to initialize bts->si_valid to bts->si_mode_static,
i.e. start with those that are static and not to be auto-generated.

Harald Welte 8e2e22ffb3 libbsc: Add VTY command to re-send the SYSTEM INFORMATION to BTS
This is useful if you are updating some configuration parameters which
affect the content of the SYSTEM INFORMATION messages.  Currently, we
only send them at the time the RSL connection is established (i.e. when
the BTS is initialized), so if you change something, you need to bring
down and re-start the BTS.

Using the newly-introduced "bts <0-255> resend-system-information"
command, you can re-generate + re-send SYSTEM INFORMATION without
bringing the BTS down, i.e. without any radio carrier downtime.

Benoit Bolsee 79a8961ada transaction: reject calls from unidentified subscribers
A valid subscriber is indespensible when allocating a new
transaction. Return NULL if no subscriber is supplied. This
will cause unidentified subscribers to be rejected.

Note: Under normal conditions, the problem does not occour,
but it is still possible that a misbehaving MS might trigger
the problem by sending a SETUP command before authenticating
the subscriber. (unencrypted networks)

initially) with closing and opening voice loops in the MS.

Neels Hofmeyr 31eabbbbba 04.08: log protocol discriminators and message types by name
On incoming 04.08 messages, we log only the protocol discriminator in
decimal. Enhance: log pdisc and message type in hex, and also log the
protocol and message type as human readable string.

Also adjust the msc_vlr tests' log statements for wrapped rx/tx functions
of dtap from/to the MS.

Adjust the expected output of msc_vlr_tests.

Neels Hofmeyr 0871a4c087 mgcp: hack RAB success from nano3G: patch first RTP payload
The ip.access nano3G needs the first RTP payload's first two bytes to read hex
'e400', or it will reject the RAB assignment. Add flag
patched_first_rtp_payload to mgcp_rtp_state to detect the first RTP payload on
a stream, and overwrite its first bytes with e400. This should probably be
configurable, but seems to not harm other femto cells (as long as we patch only
the first RTP payload in each stream). Only do this when sending to the BTS
side.
