Harald Welte 1203de3993 [gprs] fully integrate VTY configuration into Gb proxy 
The Gb-proxy is now fully configured by config file / VTY
 2010-05-04 07:20:42 +02:00
Harald Welte 3771d09ec0 GPRS: Introduce a GPRS Gb Proxy 
The ida of the Gb proxy is to aggregate Gb links with a number of BSS
and then present all the BSSGP-VC's together inside one NS-VC to the
actual SGSN.

The code is not yet expected to be complete.

Harald Welte 24a655f140 gprs: remove msgb->nsvc pointer and replace it with NSEI and BVCI 
According to TS 08.16, the BSSGP layer needs to specify NSEI and BVCI when
executing the NS UNITDATA REQUEST primitive of the underlying NS layer.

Rather than passing around a pointer to the 'struct gprs_nsvc', we now
have NSEI and BVCI as members of 'struct obsc_msgb_cb' and set them
when BSSGP hands a message down to NS.

NS then does a lookup of the 'gprs_nsvc' based on the NSEI parameter.

Harald Welte 645609ddc8 gprs: Use new msgb->cb[] for storing a pointer to the NS-VC through which it was received 2010-05-04 07:20:42 +02:00
Harald Welte f030b210e8 GPRS: Modularize the NS implementation 
* move UDP listener code for NSIP from input/ipaccess.c and into gprs_ns.c
* add PDU type, IE and CAUSE values for later IP based 3GPP TS 48.016
* support multiple NS-VCs and their lookup based on NSVC and sockaddr_in
* maintain the remote_state (blocked/alive) for each NSVC
* introduce the concept of GPRS_NS instances, move all global vars to instance
* remove hardcoded calls to gprs_bssgp_rcvmsg() and replace it by callback

WARNING: This is not finished code.  While it will compile, it will not work
yet, as BSSGP needs to be converted to properly indicate the NSVC to which it
needs to send data.

Harald Welte 510c3920c8 gprs: Update gprs-sgsn branch to use new msgb->cb layout 
The explicit 'tlli, gmmh' members of struct msgb are gone from
current libosmocore and have been replaced by the more generic
'control buffer' mechanism.

Harald Welte 9ba500559a Create new 'gprs-sgsn' branch on top of 'gprs-conf' 
This branch contains the partial SGSN/GGSN implementation that
was originally developed as part of the gprs branch.

Harald Welte bb77c9d6cc msgb: remove smsh, llch, tlli and gmmh 
This is a lot of GSM/GPRS specific stuff in struct msgb which we want
to avoid.  The 'control buffer' will replace them.

be the preferred type in osmocore. (coming from stdint.h vs sys/types.h)

Holger Hans Peter Freyther 23ba4747d1 select.c: Make the ugly hacker uglier... 
Right now I'm seeing crashes when removing a link and deleting
it and I need this hack to make it not crash. We will have to
understand if llist_for_each_entry_safe has a bug or if we are
doing something bad with the list (anchors not properly initialized).

Harald Welte cc6313cc69 logging: fix default initialization of per-category loglevels 
Before this patch, there was a bug in the code caused by a memcpy
from one data structure to another. unfortuantely the data structures
were not the same, so we have to explicitly iterate over the array
and assign the structure members manually.
