Add classmark check function according to GSM 04.08 Chapter 10.5.1.7
Fix interface to use unsigned for unsigned value.

This function returns the number of bits necessary to pack osmo_earfcn
into Repeated E-UTRAN Neighbour Cells IE (3GPP TS 44.018 Table
10.5.2.33b.1).
|
|
|
|
| |
This can be used with get_value_string() to improve debugging output.

Add structure representing group of EARFCNs with common priority,
threshold etc.
Add functions to populate this structure.

For 3G, I need a BCD composer/parser similar to gsm48_generate_lai()/
gsm48_decode_lai(). Those functions also handle a trivial extra
member (lac) which I don't need in this way for 3G.
So create new functions to take on the MCC+MNC BCD handling and call those
from gsm48_generate_lai() and gsm48_decode_lai(). In this way, the 3G code
in openbsc can use only the BCD functionality without code duplication.

Various users of gsm48_hdr apply the same hardcoded shifts/bitmasks to obtain
the transaction ID encoded in the upper nibble of the protocol discriminator.
Centralize. Patch for openbsc.git will follow.

Add inline functions for both release <= 98 and release >= 99 as well as a
default define. Use the release 98 by default since the current code base uses
the r98 bitmasks.
These inline functions relieve callers of the decision on masking bits of the
protocol discriminator and message type octets.
Also add a define for the protocol discriminator extension to one octet length
(GSM48_PDISC_EXTEND).
Apply new pdisc function in gsm0480.c.

Add basic data structure for System information Type 2quater.

Previously the presence of header and data blocks were communicated
in-band which decreases code readability and makes it unnecessary hard
to add support for new hardware.
Note: OsmoBTS have to be modified to take advantage of extended
ph_data_param structure.

These functions are currently part of openbsc but also needed by
other projects.
The function have been renamed as follows:
gprs_apn_to_str -> osmo_apn_to_str
gprs_str_to_apn -> osmo_apn_from_str

this was detected by debian packaging, as the associated gsm_03_41 test
case fails on big endian machines like ppc.

For some reason the structure is closer to be a LV (length
and value). The value is actually a tag but it is counted
inside the length. Introduce an overload of the parse function
to provide an offset for the length. This will be taken from
the returned length.

The current functions are used to 'qualify' an APN from the
user-supplied APN name (name identifier) towards the fully-qualified
APN name which is used in the .grps DNS zone.

These patches enhance the Supplementary Service (SS) processing from
only being able to handle USSD to other SS, specifically activation,
deactivation and interrogation of those SS. Registration is not yet
implemented.
include/osmocom/gsm/protocol/gsm_09_02.h has been added with needed
values for SS.
Modified by Harald Welte to keep the old ussd-only functiosn for API/ABI
stability.

A pointer to struct osmo_fd is used in a few prototypes declared in
gsm/ipa.h, but is neither declared explicitly nor is such a
declaration reachable via the given include directives.
This patch adds a forward declaration of this type to ensure proper
compilation.

As we are breaking builds by moving functions from libosmo-abis to
libosmocore anyway, we might as well give functions more appropriate
names. ipaccess is a company, while IPA is the multiplex protocol, and
CCM is the protocol used for establishing identities on the IPA
multiplex.

libosmo-abis is about forming A-bis interfaces/lines by means
of E1 or the IPA multiplex (or possibly other link layers).
The IPA multiplex is used in other contexts, such as the Control
interface, or the A interface. In that context, it makes sense to
have generic IPA related functions in libosmocore.

This adds support for A-over-IP and LCLS related message/IEI
definitions.
Old definitions are in decimal, which is very hard (at least for me)
to compare with the binary tables in the spec. Hex is much easier
to manually compare for completeness/correctness. I didn't touch
the existing definitions, but think they should move to hex, too.

Rename NM_ATT_O_REDUCEPOWER to NM_ATT_OSMO_REDUCEPOWER, which
makes it more clear that this is an osmcoom specific attribute.
Also, we cannot simply overload 0x01 as an already defined OML
attribute. The problem is quite simple: When we use abis_nm_att_tlvdef
during the TLV parse, 0x01 will match to NM_ATT_ABIS_CHANNEL,
which is defined as { TLV_TYPE_FIXED, 3 }.
So instead, we need to introduce a new abis_nm_osmo_att_tlvdef[],
which has to be patched into abis_nm_att_tlvdef[] by the means of
tlv_def_patch(), exactly how we do it for bs-11 and nanobts specific
attributes.
I'm using 0xfe for the attribute, as 0xfe doesn't overlap with the IPA
specific attribues (and we might want to combine/merge the 12.21 plus
IPA plus osmocom spefici attributes)

If LAPDm receives an I-Frame while there already is an I-Frame in the
tx_queue the code generates an additional RR (to acknowledge the
received I-Frame). Instead, N(R) of the I-Frame in the tx_queue should
be updated to ACK the data.

This API allows you to get the lapdm_datalink for a SAPI. It's needed in
the lapdm_test, so make it public.

The legacy 7bit conversion functions (those without the '_n_' in the
name) gave wrong return values on 64 bit platforms due to unproper
signed/unsigned conversions and the usage of SIZE_MAX.
This patch fixes this by using a smaller max size (see
GSM_7BIT_LEGACY_MAX_BUFFER_SIZE, currently set to 64k) for the legacy
wrappers and by using unsigned int for max_septets.
In addition, there are tests now that check the return values of
legacy encoding and decoding.

abis_nm_pchan4chcomb will return a pchan for a given channel
combination but returned a value of the channel combination.
Fix it to return the physical channel combination.
