Drop OpenSSL/libcrypto dependency, use osmo_get_rand_id() instead.
Backport

"
Migrate from OpenSSL to osmo_get_rand_id()
This avoids potential licensing incompatibility and makes integration of
Debian packaging patches easier.
"
Apply similar changes in bsc-nat, mm_auth_test etc.
Tested manually with osmo-nitb and sysmoBTS, and verified that Authentication
Requests send heterogenous RAND tokens.

This change adds support for both comp128v2 and comp128v3 GSM
A3/A8 algorithms. Since they already implemented in libosmocore,
the corresponding it's API is used.

libosmocore change-id I857af45ae602bb9a647ba26cf8b0d1b23403b54c adds
OSMO_VALUE_STRING to compose value_string arrays with the exact enum names as
entries. Use instead of identical local macros in two places.

iu_event_type_names[] and auth_action_names[] lacked a { 0, NULL }.

Rather than having a 'private' structure for kc, sres and rand, we
now finally (with 4 years delay) use osmo_auth_vector from libosmogsm,
which encapsulates authentication vectors that can be either GSM
triplets or UMTS quintuples or a combination of both.
gsm_auth_tuple becomes a wrapper around osmo_auth_vector, adding
use_count and key_seq to it.
key_seq is no longer initialized inside gprs_gsup_messages.c, as there
is no CKSN / key_seq inside the message anyway. If a usre of the code
needs key_seq, they need to manage it themselves.

Make sure a new auth tuple is initialized after
db_get_lastauthtuple_for_subscr() returns an error, i.e. if no tuple is present
for the subscriber yet.
Before this patch, the first key_seq depended on the typically uninitialized
value that was present in auth tuple's key_seq upon calling
auth_get_tuple_for_subscr().
The very first key_seq used for a new subscriber will now always be 0. Before,
it used to be mostly 1 ("(0 + 1) % 7"), but depended on whether the key_seq was
indeed initialized with 0, actually by random.
|
|
In auth_get_tuple_for_subscr(), add missing condition to match incoming
key_seq with stored key_seq, so that re-authentication is requested for
mismatching key_seqs.
Add test for this issue.
|
|
AUTH_NOT_AVAIL == 0, so this is no functional change.
|
|
Instead of using hardcoded -1 for errors, include -1 in the enum auth_action
type; apply its use.
In the mm_auth test, the string output changes from '(internal error)' to
'AUTH_ERROR', since now the proper enum value is used in auth_action_names[].
|
|
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].

libosmogsm is a new library that is distributed in the libosmocore.
Now, openbsc depends on it. This patch gets openbsc with this
change.
This patch also rewrites all include path to the new
osmocom/[gsm|core]
