ranap_cause_str() already had a const input argument, but the
HNBAP and RUA equivalents for some reason had a non-const input.

This function is analogous to existing ranap_decode_*_itemies_fromlist()
which we already had.
This is needed in an upcoming osmo-hnbgw patchset where we need to parse
the ReleasedItems in order to track RAB release progess in order to
gather KPIs on RAB release.

So far we are omitting the GlobalRNC-ID from all of our RANAP RESET
messages, because clearly, in 3GPP TS 25.413 9.1.39, the Global RNC-ID
is listed as optional.
OTOH, section 8.26.2.1 says
"The RNC shall include the Global RNC-ID IE in the RESET message."
Apparently an RNC must include this ID, while a CN omits it.

Rename the "ctx" argument of ranap_cn_rx_co and ranap_cn_rx_cl to "priv"
as it is private user data passed to the callback.

ranap_cn_rx_co and ranap_cn_rx_cl both have a void *ctx argument, that
gets passed to:
* a callback function and
* to various decode functions in the same file.
As it is named "ctx", it looks like a talloc context. But the decode
functions don't use ctx at all and so in reality it is private userdata
for the callback. It is used as such by test/hnb-test-rua and in
osmo-msc.
Start cleaning this up by removing the unused ctx args, a future patch
will rename it to priv and yet another patch will fix a compiler warning
in test/hnb-test-rua by properly using it as userdata arg.

Fix warnings from generated asn1 code in order to build osmo-iuh with
werror in a future patch:
../../include/osmocom/hnbap/HNBAP_CriticalityDiagnostics-IE-List.h:29:23: error: ‘struct HNBAP_CriticalityDiagnostics_IE_List__Member’ declared inside parameter list will not be visible outside of this definition or declaration [-Werror]
These visibility warnings come from "SEQUENCE … OF SEQUENCE" definitions
in the asn1 source files, as described in detail here:
https://github.com/vlm/asn1c/issues/430
It is not possible to tell gcc to just ignore these warnings since they
don't have their own type (unlike e.g. -Wuninitialized). Also it seems
like a huge effort to patch this in asn1c.
So work around the problem the same way the author of the issue worked
around it by rewriting the lines to "SEQUENCE … OF …-Value" and adding
a "…-Value ::= SEQUENCE" line below. Add a script in
asn1/utils/asn1_restructure_sequence_of_sequence.py for the
transformation and apply it.

The message encoder functions that decode a message to a struct
ranap_message are only accessible via a callback function that is passed
to ranap_cn_rx_cx The decoded ranap_message only lives inside the callback
since it is freed by ranap_cn_rx_cx when the callback is done. In some
situations this might make using the decoder incredibly difficult since
it is not possible to keep the decoding results for an extended amount
of time. Lets put the decoding into a separate function and use this
function in ranap_cn_rx_cx. Then lets make the decoder and the free
function public so that the decoder can be used in a more open way.

This is an option enabled by default and not existent as cmdline param
since asn1c 0.9.26.
For some reason, when dropping it, asn1c generates different description
comment section on related files. In any case, this makes hnbap look
like other libraries which already got this param removed and hence also
generateds code looks the same.

Other libraries already use ASN1C_PREFIX except the HNBAP one. Let's use
it here to avoid collisions.
All new include/osmocom/hnbap/HNBAP_*.h and src/hnbap/HNBAP_*.c are

If we receive a HNB-REGISTER-REQ with a cell ID which is already used
by another registered NNB, log an error and send HNB-REGISTER-REJECT.
Tested manually by running two 'hnb-test' programs concurrently (they
need to listen on different telnet ports; this port is hard-coded so
I compiled two different hnb-test binaries).
Then I issued the 'hnbap hnb register' command on the telnet interface
of each, and verified that the correct action is logged by osmo-hnbgw.
Both hnb-test programs can connect, but only one of them can register
at a time. Killing a registered 'hnb-test' program terminates its
connection and allows the previously rejected one to register.
The new rejection log message looks like this:
hnbgw_hnbap.c:429 rejecting HNB-REGISTER-REQ with duplicate cell
identity MCC=901,MNC=99,LAC=49406,RAC=66,SAC=43947,CID=182250155

Instead of listing each and every context map, rather output a summary of
context counts.
Rationale: in a list of a hundred HNBs, I don't want to also see a dozen (or
potentially thousands of) context map lines for each. Furthermore, the conn IDs
aren't necessarily useful on network traces either.
For example, what was shown as SUA Id is incidentally the SCCP Reference, but
this is not a hard requirement and may change. Also, the reference is shown in
wireshark as a hex in mismatching byte order ... so rather don't bother.
The result now looks like
OsmoHNBGW> show hnb all
HNB (r=192.168.0.124:29169<->l=192.168.0.9:29169) "000295-0000152614@ap.ipaccess.com"

sccp-address msc
point-code 0.0.1
sccp-address sgsn
point-code 0.0.2

remote-addr msc
iups
remote-addr sgsn
Enforce that both IuCS and IuPS use the same ss7 instance. In the future, we

To help split openbsc.git to separate MSC and SGSN repositories, place the
common Iu interface related code here in libosmo-ranap. Also apply various
improvements while moving (from intermittent code review).
The code depends on libosmo-ranap tightly. One reason to want this separate
from libosmo-ranap could be that it uses libosmo-sigtran, accepting an sccp
instance. However, including in libosmo-ranap is the simplest way to go. The
osmo-iuh build depends on libosmo-sigtran anyway because of OsmoHNBGW, and all
current users of libosmo-ranap also naturally link libosmo-sigtran already.
Apply prefix ranap_iu_ and RANAP_IU_ to allow smooth transition from the
openbsc.git iu_ to the libranap ranap_iu_ implementations.
Prune unneeded #include statements.
Instead of sccp_addr, store an rnc pointer in the ue_conn_ctx. To facilitate,
also:
- Move iu_rnc struct to iu_client.h (as ranap_iu_rnc).
- Instead of sccp_addr, pass rnc to ue_conn_ctx_alloc().
- Pass a local struct new_ue_conn_ctx containing the sccp_addr and conn_id up
the RANAP handling stack in case of an InitialUE message.
- Separate the InitialUE message handling from cn_ranap_handle_co(), by moving
to new and separate cn_ranap_handle_co_initial(), so we can still pass a
looked-up ue_conn_ctx to all other cn_ranap_handle_co() code paths.
- Allocate the ue_conn_ctx only in ranap_handle_co_initial_ue(), not as early
as before.
Note that we are not actually ever using the rnc pointer now present in
ue_conn_ctx. It could be used for more concise paging, to first page only the
RNC where we last saw the subscriber. So far we page all matching LAC/RACs.
Tweak error logging: use __func__ instead of writing the function names as
string constants.
In iu_client_vty.c:
- Move the asn.1 debug commands from logging over to the iu node. They are not
specific to the logging target. They could qualify for an entirely separate
'asn1' root node, but for simplicity place under 'iu'.
- Add the 'asn1' commands to ranap_iu_vty_config_write(), so far missing.
- remove the legacy "net." from a VTY error message, it is not known which name
the parent node of 'iu' has.

libosmo-sigtran now has a "proper" SCCP/M3UA stack, so we can make our hnb-gw
3GPP compliant by switching from the old SUA code to the new universal SCCP
user API with support for (currently) M3UA and SUA.
Main changes:
Use one cn_link to STP: We will connect to the core network using an (Osmo)STP
instance that routes to MSC and SGSN, so we want one SCCP link instead of two.
The only difference between IuCS and IuPS is a different remote osmo_sccp_addr.
This has various effects through the messaging code; the patch is a bit larger
than I would like, but it is hard to separate out truly independent smaller
changes.
CS or PS domain was previously flagged in the separate cn_link, as ctx pointer
for two separate sccp_sap_up()s. Now there's just one such ctx, so determine
is_ps from the RANAP Domain Indicator, or from the conn's hnbgw_context_map:
- Add is_ps to context_map_alloc_by_hnb().
- To find a matching context, the RUA ID alone is no longer sufficient, also
match is_ps (possible optimization todo: separate lists).
We would send separate CS or PS Reset messages based on the cn_link, instead
send both CS and PS Reset at the same time for the single cn_link. This could
be adjusted to detect presence of MSC or SGSN instead.
Pending: adjust the VTY config to reflect that there is only one remote
address. Place a TODO comment for that.
Smaller changes:
rua_to_scu(): populate called and calling addresses for N_CONNECT and
N_UNITDATA.
Remove DSUA.
Don't build dummy_cn, which is still implemented on SUA. Mark todo to maybe
re-include it based on M3UA later.
In hnbgw_cnlink, place sccp related items in a separate sub-struct.
Do not keep an llist of cn_links, just have the one. Remove iteration and list
management.
Change jenkins script to build libosmo-sccp master.
