6812782462 hlr_auc_gw: Allow Milenage RES length to be reduced
Some USIM use shorter RES length than the 64-bit default from Milenage.
Such cases did not interoperate with the hlr_auc_gw implementation. Make
it possible to configure the RES length 4..8 octets, i.e., 32 to 64
bits) to support such USIM.

d85e1fc8a5 Check os_snprintf() result more consistently - automatic 1
This converts os_snprintf() result validation cases to use
os_snprintf_error() where the exact rule used in os_snprintf_error() was
used. These changes were done automatically with spatch using the
following semantic patch:

84dc137056 hlr_auc_gw: Add GSM-AUTH-REQ command
This can be used instead of SIM-REQ-AUTH to derive Kc and SRES values

3e6547b5e8 hlr_auc_gw: Add support for processing command line operations
This allows hlr_auc_gw to be used to run a single operation without
having to use it as a server. This can be useful, e.g., for generating
GSM authentication triplets for external programs. For example:
./hlr_auc_gw -m hlr_auc_gw.milenage_db "SIM-REQ-AUTH 232010000000000"

The notes about using only fixed GSM authentication triplets were not
really up-to-date with the implementation. Milenage and GSM-Milenage
were available for EAP-SIM, EAP-AKA, and EAP-AKA'.

5daba48ca7 hlr_auc_gw: Use 5 bit IND for SQN updates
Change the SQN generation mechanism to use not time-based Profile 2
as described in 3GPP TS 33.102 Annex C.3.2. The previous implementation
used void IND (i.e.., all of SQN was SEQ1). The new default uses 5 bits
of SQN as IND. The length of IND can be configured on the command line
with the new -i<IND len in bits> parameter. -i0 would make hlr_auc_gw
behave in the same way as the previous implementation.

3642c4313a Annotate places depending on strong random numbers
This commit adds a new wrapper, random_get_bytes(), that is currently
defined to use os_get_random() as is. The places using
random_get_bytes() depend on the returned value being strong random
number, i.e., something that is infeasible for external device to
figure out. These values are used either directly as a key or as
nonces/challenges that are used as input for key derivation or
authentication.

The remaining direct uses of os_get_random() do not need as strong
random numbers to function correctly.

0e574b07f8 Move hlr_auc_gw into hostapd directory
This is a separate program and is used mainly with hostapd, so it is
better to move this into the hostapd subdirectory now that Milenage
code has already been moved into src/crypto. Milenage was the only
generic component in hlr_auc_gw.
