Hold on with the GSM 04.11 RP-ACK/RP-ERROR that we send to the MS until
we get a confirmation from the ESME, via SMPP DELIVER-SM-RESP, that we
can route this sms somewhere we can reach indeed.
After this change, the conversation looks like this:
MS GSM 03.40 SMSC SMPP 3.4 ESME
| | |
| SMS-SUBMIT | |
|------------------->| |
| | DELIVER-SM |
| |---------------->|
| | |
| | DELIVER-SM-RESP |
| |<----------------|
| GSM 04.11 RP-ACK | |
|<-------------------| |
| | |
Before this patch, the RP-ACK was sent back straight forward to the MS,
no matter if the sms can be route by the ESME or not. Thus, the user
ends up getting a misleading "message delivered" in their phone screen,
when the message may just be unroutable by the ESME hence silently
dropped.
If we get no reply from the ESME, there is a hardcoded timer that will
expire to send back an RP-ERROR to the MS indicating that network is
out-of-order. Currently this timer is arbitrarily set to 5 seconds. I
found no specific good default value on the SMPP 3.4 specs, section 7.2,
where the response_timer is described. There must be a place that
describes a better default value for this. We could also expose this
timer through VTY for configurability reasons, to be done later.
Given all this needs to happen asyncronously, ie. block the SMSC, this
patch extends the gsm_sms structure with two new fields to annotate
useful information to send the RP-ACK/RP-ERROR back to the MS of origin.
These new fields are:
* the GSM 04.07 transaction id, to look up for the gsm_trans object.
* the GSM 04.11 message reference so the MS of origin can correlate this
response to its original request.
Tested here using python-libsmpp script that replies with
DELIVER_SM_RESP and status code 0x0b (Invalid Destination). I can see
here on my motorola C155 that message cannot be delivered. I have tested
with the success status code in the SMPP DELIVER_SM_RESP too.

Previously we required pcap.h unconditionally which causes embedded
build failure because it's not included in current version of out poky
toolchain. We can add it to toolchain but it's only necessary for
utils/osmo-meas-pcap2db which is not built for sysmobts anyway so it's
easier to just make this dependency optional and build osmo-meas-pcap2db
only if it's available - similar to the way we build osmo-meas-udp2db.

Previously it was only in gsm_bts_model which is not initialized on BTS
side. It's more convenient to have it in the struct which is available
to BTS as well.

Supporting SI2quater as per 3GPP TS 44.018 will require chnages to the
way System Information is stored because it uses 1:n instead of 1:1
mapping between SI type and generated SI content. This should not affect
other SI types though. To facilitate this transition:
* convert the code to always use GSM_BTS_SI helper instead of accessing
buffer directly
* make helper more robust by adding extra parenthesis
* add similar helper for gsm_lchan
* add function estimating number of SI2quater message to hold configured
number of (U|E)ARFCNs
* add SI2q index/count fields and pass them to rest_octets generator
explicitly
* internalize buffer access in generate_si* functions

From a human admin viewpoint it doesn't make sense to count the messages sent:
When we use TMSIs, we first send a LU Accept with a new TMSI, and then expect
the MS to respond with a TMSI Realloc Complete message. When that fails to come
through, the LU actually ends in failure, even though a LU Accept was sent.
If a conn breaks/vanishes during LU, we cancel the LU without sending any reply
at all, so the failed LU would not be counted.
Instead, count Location Updating results, i.e. completion and failures.
(With the new VLR developments, LU counters need to be triggered in completely
different places, and this patch prepares for that by providing sensible
counters.)

The timer T3186, which is described in 3GPP TS 44.060, is using 3
bits of the si13 mac block. This requires special encoding. In the
case of T3186, the value is encoded by the formula: bits = t/500-1.
Our implementation uses the formula bits=t/500, which is incorrect.
