There is already a group of similar functions for L1, L2 and L3,
but L4 was missing. The L4 is usually used for parsing of complex
L3 messages, such as SS/USSD and SMS.
This change introduces a similar halper for L4.

There was gsm0480_l3hdr_push() declared in a header file, but
not exposed in 'libosmogsm.map'. Furthermore, for some reason
it was a part of GSM 04.80 API, what is not actually correct.
Let's rename this symbol, and properly expose it as a part of
the GSM 04.08 API. Also, let's introduce an auxiliary wrapper
for messages, where the transaction identifier is required
(see GSM 04.07, section 11.2.3.1.2).

In order to be able to transfer SS/USSD messages via GSUP,
this change introduces the following new message types:
- OSMO_GSUP_MSGT_PROC_SS_*,
and the following new IE:
- OSMO_GSUP_SS_INFO_IE
which represents an ASN.1 encoded MAP payload coming to/from
the mobile station 'as is', without any transcoding.

Unlike TCAP/MAP, GSUP is just a transport layer without the
dialogue/context. This prevents us from having session based
communication, required e.g. for USSD. But we can emulate
TCAP dialogue by adding additional IEs, which would allow
to relate each message to a particular session.
This change introduces the following IEs:
- OSMO_GSUP_SESSION_ID_IE,
- OSMO_GSUP_SESSION_STATE_IE,
which optionally can be used to indicate that the message is
related to a session with given ID, and to manage session
state, i.e. initiate, continue, and finish.

Before this commit, for library projects (containing LIBVERSION in some
Makefile), the entire commit list was not stored into the changelog, but
only a few lines from TODO-RELEASE files.
This is a bad approach for several reasons. First, because that file was
only aimed at containing API/ABI breaks, and not the full relevant
changeset (like bugfixes, new features, etc.). Second, because it relies
on every developer making API/ABI changes to remember to store the
change in there during commit break time.
Let's instead always store the entire commit list in changelog, and
let's use TODO-RELEASE only as a list of hints for the maintainer to
help him evaluate how LIBVERSION needs to be bumped for each library.
Other tools such as osmo-abi-check.git can be used to help with the
process of decission too.
Let's take the opportunity too to only commit stuff already added to the
staging area, as it proved easier to manage from my personal experinece
making latest releases.

As it was already documented before, the 'ss_request' struct has
a rudiment of deprecated 'ussd_request' struct - the 'ussd_text'
field. It represents the data either of an INVOKE component,
either of a RETURN_RESULT component, encoded as ASCII in case
if DCS is 0x0f (i.e. decoded by the code itself), otherwise
raw bytes 'as is'.
Previously, there was no possibility to distinguish between
ASCII and raw bytes with different DCS. Moreover, the payload
decoding is not desired in some cases.
Let's introduce the new fields, which will carry the raw
unmodified payload, its length and DCS (Data Coding Scheme).

The function _osmo_fsm_inst_term() terminates all child FSMs befor
it calls fi->fsm_cleanup(). This prevents the cleanup callback to
perform last actions on the child FSMs (e.g.
osmo_fsm_inst_unlink_parent()).
- Since moving the cleanup callack to the beginning of the function
would alter the termination behavior and possibly cause malfunction
in already existing implementation that use OSMO fsm, a new
optional callback that is called immediately at the beginning of
the terminatopn process is added.

When a bad GSM voice frame is received, it's being replaced
by a silence frame. This may cause unpleasant audio effects.
This change implements a functionality to craft a replacement
frame from the last known good frame. Currently, only FR is
supported, support for other codecs may be added latter.

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.

GSUP transmits AUTS for UMTS authentication procedures, and OAP uses the same
procedures to authenticate. osmo-gen-vec is a utility program that passes AUTS
to our osmo_auth_gen_vec_auts() API.
According to 3GPP 33.102 6.3.3, AUTS = SQN^AK || MAC-S, which are 6 || 8 == 14
bytes. This is confirmed by 24.008 9.2.3a where the TLV has 16 bytes, TL = 2
and AUTS being the V = 14.
It is not harmful for milenage_gen_vec_auts() to pass two more AUTS bytes. But
writing 16 bytes to a GSUP struct is a potential problem when passing in a 14
byte long AUTS buffer to the GSUP API, which then reads past the AUTS buffer.
The API implies the length, so far to be 16, so passing in a 14 byte buffer to
GSUP would require copying to a larger buffer first.
Fix this by using a length of 14 for AUTS everywhere instead.
This constitues an ABI breakage, we may handle it as a "fix before an official
release", otherwise we need a version bump.
The OAP protocol document has also been updated, needs an update in the
osmo-gsm-manuals as well.

This reverts commit ed9d6da5df98538adc70aa03cb569eb9505d04b6.
The commit is good as such, but it causes many compiler warnings in the OpenBSC
build. We want this to be re-applied as soon as we have patches ready that fix
the fallout in openbsc.git.

Update internal API (for GPRS cipher implementors): make it compliant
with ETSI TS 155.22. External API left untouched.
|
|
Previously the presence of header and data blocks were communicated
in-band which decreases code readability and makes it unnecessary hard
to add support for new hardware.
Note: OsmoBTS have to be modified to take advantage of extended
ph_data_param structure.

Shipping our own private copy of talloc was a good idea in 2008,

Bump the ABI version of libosmovty and we need to do this
recursively to force rebuilds of our software.
|
|
Currently every time a node is added to enum node_type, this
constitutes an ABI change, since _LAST_OSMOVTY_NODE will get
incremented accordingly. In this case, every project that adds new
node type based on that value will have to be recompiled.
This commit adds 4 spare node type values, which can be replaced
one-by-one by new real types until they are exhausted to avoid
this kind of ABI change.

This commit provides stats configuration similar to the log
configuration.
The following vty commands are added to the config node:
stats reporter statsd Create/Modify a statsd reporter
no stats reporter statsd Remove a statsd reporter
To actually configure a reporter, the config-stats node is entered
when the "stats reporter" command has succeeded. The following new
vty commands are available there:
local-ip ADDR Set the IP address to which we bind locally
no local-ip Do not bind to a certain IP address
remote-ip ADDR Set the remote IP address to which we connect
remote-port <1-65535> Set the remote port to which we connect
prefix PREFIX Set the item/counter name prefix
no prefix Do not use a prefix
enable Enable the reporter
disable Disable the reporter

Currently large values for Bmax default MS get sliced since a uint16_t is
used as the type of the corresponding parameter of bssgp_tx_fc_bvc.
GSM 48.018, 11.3.2 which in turn refers to 11.3.5 specifies a maximum
of 6MB (0xffff * 100).
This commit changes the type to uint32_t to cover the full value
