These are not needed any more. We used them for u_int
types but we now use uint which comes from stdint.h

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]

The reason for this is quite simple: We want to make sure anyone
running a customized version of OpenBSC to operate a network will
have to release all custom modifiations to the source code.
|
|
If the GGSN restarts, its restart counter will increase. We can
detect that and accordingly release/delete all PDP contexts for
that GGSN.

sgsn_rx_sndcp_ud_ind() can no longer make the assumption that msgb_bcid() is
valid, as this is only true for an un-fragmented SN-PDU. So instead,
we now store the RAID in the SNDCP Entity and pass it as an explicit
argument to sgsn_rx_sndcp_ud_ind().
|
|
The 'bssgp_paging_info' contains a pointer to the P-TMSI, and not
the P-TMSI itself. The reason is that it is an optional BSSGP IE.
|
|
Otherwise we will end up leaking memory in the SNDCP layer...

We'll need to push data both before and after, so make sure there
is both headroom & tailroom

We now have a function that generates BSSGP PS and CS paging request.
It is called from the libgtp code when we receive a GTP packet from
the GGSN for a MM context that is in SUSPEND state. We then issue
a PS paging request to the Cell with the BVCI where the last RA update
was being performed.
TODO: We still don't enqueue the GTP packet (and transmit it on paging
complete), and we don't rate-limit the paging requests, i.e. every GTP packet
will trigger another paging request.
We probably also need some kind of logic that marks the phone as UNREGISTERED
if it doesn't respond to paging requests for some time.

This only works for packets that are small enough to not need
fragmentation at the SNDCP layer (dns queries, ntp and the like).
It requires libgtp built from OpenGGSN dc3744fda045f9fca83de6881176987335a309a8
or later. Plain 0.90 will NOT work.
Using this version, I could see bi-directional traffic from various
phones going all the way through BTS, OsmoSGSN, OpenGGSN and being routed
to and from the real internet. Time to celebrate...

We have to copy the sin_addr.s_addr, rather than the entire sin_addr. The
latter results in the destination interpreting it as an IPv6 address, as
the only differentiator between IPv4 and IPv6 is the size of the payload
of this IE.
|
|
|
|
This so far only works for UNIT-DATA and only if the N-PDU is not fragmented at
the SNDCP layer.

The libgtp return value is already a timespan value, not a
wallclock time.

* store LLC SAPI as part of PDP ctx
* store NSEI + BVCI as part of MM ctx
* export gsm48_tx_gsm_act_pdp_acc() and call it from sgsn_libgtp.c
* create and use gsm48_tx_gsm_act_pdp_rej for error cases
* print SAPI as part of VTY show pdp

We never want to support multiple sgsn's within one process, so
there is no point in passing them around all the time.

libgtp of the OpenGGSN project will allow us to speak the GTPv0/v1
protocol of the interface between SGSN and GGSN.
This commit includes code for the main libgtp integration (file
descriptor, select loop, timer) as well as code to encode/send
a CREATE PDP CONTEXT request.
