The old ipa_msg_recv() implementation didn't support partial receive,
so IPA connections got disconnected when this happened.
This patch adds the handling of the temporary message buffers and uses
ipa_msg_recv_buffered().
It has been successfully tested by jerlbeck with osmo-nitb and
osmo-bsc.

In case the max_power_reduction changes, issue a new Set Radio
Carrier Attributes command. OML 12.21 allows to not include the
ARFCN list and the semantic I picked/understand is that a partial
update is possible.
Fixes: SYS#267

Add the control interface with no hierachy right now and implement
the first command to list IMSI + Context Address of active sessions.
sgsn_cmd_handle could share more code with bsc variant.

For GPRS the look-up via bts/trx does not make any sense and would
introduce bad depdencies for the SGSN. Move the look-up code to a
new file and introduce new setup methods.

This is only useful for small networks. List the IMSI and MSISDN
of all active subscribers.
Fixes: SYS#266

Sadly there is no proper foreign key relationship on the tables
that related to the Subscriber. This means we can't use a DELETE
with Cascade and need to delete everything by hand. To make things
worse maybe the SMS/Paging code is still using the subscriber
making the operation more dangerous. I had added NULL checks for
sender_id/receiver_id at 30C3 so we should not crash in this
situation.
Fixes: SYS#274

The test has been manually verified. Executing the select for
the subscribers showed:
sqlite> select * from Subscriber;
1|2014-03-23 12:12:46|2014-03-23 12:19:09|2620345||445567|1||0|
This created a subscriber with the right IMSI, MSISDN and has
it authorized.
Fixes: SYS#275

In case the BTS is connected the new attribute should be set
through OML. This is left as a todo item.

Merge the interface changes to the MNCC protocol
|
|
|
|
Rename method mncc_rcv_tchf() to mncc_rcv_data(), because the check applies
to all types of data frames, not only TCH/F data.
|
|
The new definitions are: half rate and AMR
Change of definition name for bad frame, because it applies to all types of
traffic, not only TCH/F.
Increase MNCC interface version to 4. Version 3 is skipped, because it was
used by older version of Linux-Call-Router which is incompatible with the
current version of the MNCC interface.

Rename gsm340_gen_tpdu() to gsm340_gen_sms_deliver_tpdu() to
show that it generates SMS-DELIVER TPDU and is not a generic function.
|
|
In MT-SMS the message is being delivered. Make the naming follow
that. The schema still refers to "sent" while it should be "delivered"
too.

Send the two strings that caused the read handling to misbehave.
Verify that we handle this correctly by still being able to issue
a VTY command. The CPU load issue could not be verified like this.

The size parameter of msgb_alloc is uint16_t so any length value above
65535 will allocate a msgb with incorrect size.
This patch changes the type of rdlen and rc to ssize_t (the return value
of read) and guards against the read length being larger than
UINT16_MAX.
To reproduce the issue run:
echo -en "\x00\x01\x00\x01\x01" |socat stdin tcp:localhost:2775
|
|
The first 4 bytes are the length including the length field. For
length < 4 the subsequent msgb_put(msg, sizeof(uint32_t)) will fail,
resulting in an abort. The code also expects (in smpp_msgb_cmdid()) the
existence of 4 more bytes for the SMPP command ID.
This patch checks that the length received is large enough to hold all
8 bytes in the msgb and drops the connection if that's not the case.
The issue is reproducible with:
echo -e "\x00\x00\x00\x02\x00" |socat stdin tcp:localhost:2775
|

Read returning -1 is an error here so make sure to print the actual
reason and close the socket. Before this patch we just looped over the
fd with read returning -1 every time.
EINTR is handled to not cause an error and we don't need to check
EAGAIN/EWOULDBLOCK since the callback is only called in case there is
something to read.
To avoid copy&paste issues the check is implemented as a macro and the
log message moved into a separate if.

Make sure that bsc_gsmnet->bsc_data->rf_ctrl is initialized for
NITB. In commit a9fae1ae66df57f76a0aedbd0b56228959d37d56 the
conditions for the rf_ctrl was removed but it was still needed
for the NITB.
Fixes regression from:
a9fae1ae66df57f76a0aedbd0b56228959d37d56
bsc: rf_ctrl will always be created, remove the NULL checks

For operation we want to switch the access-list of a BSC at runtime
in a programatic way.

It is of interest to know the MCC/MNC that is broadcasted at the
specific position.

Change the splitting of the ctrl_test_runner.py. Make sure that
we get one element and all the rest.

Right now this only works for IP based BTS like the sysmoBTS and
by dropping the OML link.

Add the framework for adding more setting commands.

|
When one SMS has been delivered check if a second SMS can be scheduled
to that subscriber. If nothing can be scheduled kick the normal SMS queue
as one slot has become free now. Otherwise send the SMS and create a
pending entry.
|
|
It was possible that two SMS would be delivered at the same time
which violates GSM 04.11. We should solely rely on the sms queue
to schedule more SMS to the subscriber.

I have manually tested this by entering the VTY command and
observing the CTRL interface using wireshark.

As can clearly be seen from SMPP Spec v3.4 Chapter 5.2.19,
a SUBMIT-SM with data_coding == 0x08 is UCS2, not with 0x80.
Thanks to ciaby@rhizomatica.org for reporting the bug.

Each RP-DATA should have a unique msg reference. Currently 42 is
used for all of these. Remember the last reference we used and
increment it on the next SMS. Do not track if the reference is
still in use a clash is a lot less likely now. First unless SMPP
is used only one SMS is delivered at a time, second the transaction
space is a lot smaller than the one for the reference.

The interface can be accessed through CTRL and a socket. But currently
it is only available when the socket interface has been configured.
Create the interface all the time but only listen on the socket when
a path has been specified.

This can be used for the description field that requires some
special handling for newlines.
|
|
For the max power reduction we will need to have a different range
method. It will need to check if the value is even. Make the set,
get and verify methods available through a macro.

With the current multiplication we might end up with 19999 as
time on i386. When we round it ends up as 20000 on i386 and
should work the same on AMD64.
|
|
On AMD64 we had a difference in the test result most likely due
the bigger size of integers.
|
|
Should fix on AMD64:
mgcp_test.c: In function ‘sendto’:
mgcp_test.c:318:10: warning: format ‘%d’ expects argument of type ‘int’, but argument 5 has type ‘size_t’ [-Wformat]

So far, the jitter computation has been based on output timestamps.
This patch uses the input timestamps instead and resets jitter
computation on SSRC changes.
