The guaranteedBitrate lowers from 12200 to 6700, which is mimicking the values
found in a trace from a production 3G environment. So far we have no reason to
choose these values other than knowing that other operators seem to do this.
This came up while trying to fix voice RAB for the nano3G, but this patch had
no effect on that. Now that it's here, we might as well keep it.

For IPv4 addresses, only 56bit of X.213 NSAP are used. The sysmocell5000
accepts such a field that is 56bits long, but the ip.access nano3G does not
(and crashes instead). Both work when zero-padded to 160bits size.
So far we used to send the IPv4 address as "raw" 32bits to the nano3G to avoid
the crash. With this zero padding we no longer need such a workaround and can
use identical config for both cells.

Properly initialize msgb talloc context in hnbgw and all tests, using the new
msgb_talloc_ctx_init().
test-ranap.c: since msgb talloc ctx is now in test_common_init(), remove msgb
talloc init here.

After libosmocore 55dc2edc89c1a85187ef8aafc09f7d922383231f which outputs
'telnet at <ip> <port>' from telnet_init_dynif(), there's no need to log the
telnet VTY bind here anymore.

This rule is bad because it re-invokes $(MAKE), but it seems to fix the
parallel build. It should probably be done differently.

This came up while fixing 'make distcheck'; this is certainly not the easiest
way but it makes sense to have the headers in include/, like we do in openbsc.
The easy alternative might be to add -I$(top_srcdir)/src to src/Makefile.am.
Remove -I$(top_srcdir)/src from src/tests/Makefile.am, no longer needed.

fix extraneous rebuild for each make invocation: touch the ranap.stamp file in
src/ as the make target suggests.
fix for 'make distcheck': ranap gen: move generated sources to builddir, not
srcdir. Thus we also -I the builddir include to pick up those headers.
hnbap and rua have the same situation as ranap (they generate numerous files
from a single make rule). Use the same makefile semantics for those two
(commit for ranap gen omitted the same changes for hnbap and rua).
The generated headers are thus moved to include/osmocom/*/, so adjust #include
statements accordingly (*_common.h, *_ies_defs.h).
Also move hnbap_common.h to include/osmocom/hnbap and rua_common.h to
include/osmocom/rua, since the *_ies_defs.h want to include them; and since
*_ies_defs.h are now in include/osmocom/*, we want a '<foo>' include now.
Also adjust gitignore.

In experr, we had line numbers in log output, which might change. Also, for
make distcheck, the path of the source file might have some '../../' added in
the log output (to indicate the src dir as seen from the build dir).
Fix both by dropping source file and line.
Also drop color while at it.

Add use_x213_nsap arg to ranap_new_msg_rab_assign_voice() and
new_transp_info_rtp(). Pass this to new_transp_layer_addr() to compose 32bit
addresses when use_x213_nsap == false.
This is analogous to ranap_new_msg_rab_assign_data().
Particularly, the ip.access nano3G does not accept x213 NSAP 56bit addresses,
so we want to send 32bit addresses there.

The decoding target pointer has to be NULL so that a new structure is allocated
by aper_decode(). Fixes a probable segmentation fault upon decoding at
test-ranap.c:77 or free of unallocated memory in test-ranap.c:81.
After aper_decode(), we still need to free the decoded struct.
This was introduced in 14da5411a4
("test-ranap: Add test case about constrained integer range decode")
Note, in that commit there is another test failure in expout (a reversed byte
order) which is "secretly" fixed in bb289e3b81
("RAB parameters: add Extended Max Bitrate").

This IE is seen in a "real life" pcap of hNodeB operation. We did not need it
so far, but add it to test the ip.access nano3G.
Comment from the future: the ip.access nano3G rebooted upon RAB Assignment
Request, and after adding/tweaking some IEs it stopped rebooting. This is one
of the changes that fixed the reboot issue. The changes have been tested
incrementally until reboots vanished, but it's not clear/hasn't been tested
whether omitting this change alone will cause reboots to re-appear.
There was a bug in the asn1c/libffasn1c APER patch that caused
constrained integer ranges to be decoded incorrectly. Add a test
case for that to avoid people falling into that trap...
Our version of asn1c/libasn1c used to have an INTEGER encoding but,
where the encoding of integers of > 2 bytes length was broken.
Add a test case to what we expect with the updated/fixed libasn1c.
If your compilation breaks, please upate to libasn1c with related
fix commited a few minutes ago.
Allow the *caller* of ranap_new_msg_rab_assign_data() to make the decision for
using 32 bit or longer IP addresses in RAB Assignment Request messages.
This requires a follow-up change in openbsc branch sysmocom/iu.
To test CSCN, I want dummy-cn to listen on 127.0.0.2 and mock IuPS instead of
the hardcoded 127.0.0.1 to mock IuCS.
Add commandline option parsing and the --bind option to set the local bind
address.
Adding the Security Mode Control command would break the current scheme of
callbacks across layers. This brought to my attention that the scheme is indeed
unnecessarily complex, so simplify it.
Instead of passing callbacks, call functions directly. Add hnb-test-layers.h to
declare those functions that cross from main to rua, to ranap and back to main
and remove the callback type definitions.
Instead of copying the NAS PDU to a newly allocated msgb, pass the data and len
directly to hnb_test_nas_rx_dtap().
Instead of repeatedly checking the gsm48_hdr length, just pass the struct
gsm48_hdr* and len around and assume the basic header length has been checked.
In some places, rename 'length' to 'len' for cosmetic consistency.
Previously the SRES was hardcoded, but the CN changed to generate the SRES.
So now, generate the SRES while still using the hardcoded Ki.
Fixes the Authentication Response message when testing IuCS Location Update.
Fix the ranap_parse_lai() part that decodes the MNC: place the *10 at the
proper MNC digit.
Add a comprehensive test for ranap_parse_lai() in test-helpers.c. Because
ranap_parse_lai() logs things, add test_common.c to test-helpers compilation
and an expected stderr output to test-helpers' testsuite.at def.
