The lle-xid encoder/decoder is needed to encode and decode llc
xid parameter messages. We need this to exchange sndcp-parameters
(SNDCP-XID) and also simple parameters such as encryption IOVs

Add basic MM Authentication test setup, with fake DB access and RAND_bytes().
So far implement simple tests for IO error during DB access and missing auth
entry.
To print the auth action during tests, add struct auth_action_names and
auth_action_str() inline function in auth.[hc].
First steps towards a new GTP hub. The aim is to mux GTP connections, so that
multiple SGSN <--> GGSN links can pass through a single point. Background:
allow having more than one SGSN, possibly in various remote locations.
The recent addition of OAP to GSUP is related to the same background idea.
(This is a collapsed patch of various changes that do not make sense to review
in chronological order anymore, since a lot of it has thorougly transmorphed
after it was first committed.)

We started with only testing the VTY but now test VTY and CTRL
interface with this python framework and might even extend this
to SMPP. So add and "--enable-external-tests" directive which
enables the external interface tests.
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.
Currently tests covering features of the GSM 04.08 specification are
spread over the si and gsm0408 subdirs in tests.
This commit merges all tests from 'si' into 'gsm0408' and removes the
'si' test sub-directory.

Decoding and encoding of FR and EFR TRAU frames are put into seperate
functions. CRC check is done to detect bad EFR TRAU frames.
The test case includes FR and EFR transcoding.
EFR support was tested with Nokia InSite BTS and Siemens BS11.
This program tests the gbproxy implementation by passing NS messages
to a modified gbproxy that dumps the resulting messages, signals, and
state.
It focusses on testing abnormal situations like port changes.

This adds in-place patching of the time information in the
MM INFORMATION message. The timezone in the 'Local time zone' and
the 'Universal time and local time zone' information elements
and the offset in the 'Network Daylight Saving Time' information
element are optionally set.
The new values are determined by the 'timezone' vty command in the
config_net_bts node. That command is extended by an optional
DST offset parameter.
Tests are provided for the vty part and for the plain
bsc_scan_msc_msg() function.

This script is similar to vty_test_runner.py but tests the control
interface instead.
It currently tests some error cases, BTS status queries, and
setting/clearing rf_locked.
* It is a trie. The max depth of the trie is the length of the
longest prefix. The lookup is O(lookuped_prefix), but as the prefix
length is limited, the lookup time is constant.
* Each node can hold the entire prefix, has place for the rewrite
rule with up to three digits.
* A trie with 20k entries will take about 3MB ram.
* Filling the trie 100 times takes ~800ms on my i7 laptop
* 10.000.000 lookups take 315ms.. (for the same prefix).
* 93/99 lines are tested, 6/6 functions are tested, 49 of 54 branches
are tested. Only memory allocation failures are not covered
* A late addition is to handle the '+' sign and to increase the number
of chars in the rewrite prefix. The timing/line coverage has not
been updated after this change.
Make sure to not ever have issues with this code again, move the
utility code to a new file and create a basic testcase. The method
currently has 100% line and branch coverage. My initial patched
missed the smpp_utils.c file and I re-did the copying (and verifying
the branch coverage)
Begin with the NAT code. It is not clear yet if we will have one
file with all the tests or will have a sub directory with *.py files.
In the long run the base class will move to the osmo-python-tests
module.
The test scripts warn about missing documentation, untested configs,
check common errors, and stub out testing individual VTY commands.
The scripts have been moved to the another osmocom repository,
python/osmo-python-tests
The features were requested by zecke.
This file is created in ./configure so we shouldn't remove it with make.
Otherwise ./configure && make clean && make check fails with:
make[3]: *** No rule to make target `atconfig', needed by `check-local'.
Stop.
I saw the old copy of the "Appendix J" code too late and I have
discovered some quirks and I am more familar with my implementation.
Most noticable 'w' only needs to be as big as the input arfcn but
requires the 'w' to be initialized. The power_of_2 implementation
differs as well (mine matches the output of wirehsark).
The f0 could be chosen in a better way but right now picking
the lower bound is the easiest. It is not clear if to use
modulo if the range is chosen in the middle. This can be improved
in the future. Right now I have no bit fiddling for range128, 256
and 1024 as I was running out of time.
GSM 04.64 8.4.2 asks to ignore UI frames if the DLCI is not known,
or if the "(V(UR)- 32) <= N(U) < V(UR)". E.g. if we want to have
V(UR) == 511 and this frame is dropped, we would ignore N(U)'s
0 to 510. Calculate the delta.
The code is based on Jonathan Santos's "LLC UI window" fix but the
issue was discovered independly.
Add --enable-nat and --enable-osmo-bsc to build applications
requiring the Osmo SCCP library to be installed. We are not
using autodiscover as this is out of fashion.
* use pkg-config from openbsc to find header and library
* move sms and timer tests to libosmocore itself
* ensure "make distcheck" works on both packages
include/sccp/sccp_types.h contain Q.713 and GSM definitions
include/sccp/sccp.h is the application interface resembling
the esentials of the UNIX socket interface.
src/sccp.c is the actual implementation of SCCP featuring
connection and UDT1 support.
tests/sccp/sccp.c is testing connection creation and formating
of the SCCP messages used by the A-interface. And
it contains a simple fuzzing test to test the
robustnes of the implementation.
This is simulating a successfull request and is causing
a segfault. The test is done with a "mock object" in this
case a minimalistic paging implementation which is enough
to show the crash.
Compare that the callback data is supposed to be the same....
