In separation of using the MGCP parsing in another context, refactor
the code to operate on a struct mgcp_config, split out the vty code
from the mgcp_protocol.c, and move the callbacks into the mgcp code.
There should be no functional changes.
|
|
Use On-Waves instead of the name I made up from the domain name.
|
|
Do not directly send data from inside the mgcp_protocol.c
implementation. Instead allocate and return a struct msgb*. The
caller can then either wrap that into the IPA protcol or directly
send it over the UDP socket.
|
|
* Call a callback when the endpoint was created, modified or deleted. This
can be used by the BSC MUX to send a MGCP packet over TCP to the right
the BSC to allocate the endpoint there with the right data, or it can be
used in the BSC to send the right commands to the BTS.
|
|
* Separate main process and protocol handling into two parts.
* Change the protocol handling to work with UDP and TCP connection
* This will allow to speak MGCP over TCP between the BSC MUX and
the real BSC.
|
|
Change the signature to take the lchan were the message is supposed
to be sent and the lchan which is supposed to be assigned.
|
|
Some NM attributes are defined differently depending on
the BTS type. Having one big nm_att_tlvdef[] table for
all BTS types is no longer sufficient. This patch
* introduces 'struct gsm_bts_model' to describe a BTS model
* adds definitions of gsm_bts_model for BS-11 and nanoBTS
* changes the abis_nm_tlv_parse() function: include a bts pointer

Whether this function changes the set or the work value depends on your
type of login. In FACTORY login it changes the set value, in FIELD login
it changes the work value (which is what is used by the BS11 to tune the
frequency).
|
|
As this user you are able to set the PLL work value which is especially
useful if your BS11 got detuned by an inaccurate oscillator in your E1
card.
|
|
Factoring out common logon functionality will allow us to logon as
different user. abis_nm_bs11_factory_logon now uses this function.
|
|
This is useful information to know and actually fixes a segfault
in rllp.c where lchan is accessed even tough it could be NULL in
case of failure.

Theses will be useful to know if we can reuse the tuples or if
we should renew. The 'issued' is currently purely informative.

This returns true if the gsm_nm_state can be considered 'running'.
Note that we also accept availability==0xff (which is a code for
no value) because according to 12.21 it is perfectly valid.

Thise two functions are interfacing with the 04.08 layer 3 to
determine if a particular message should be handled inside
the OpenBSC layer 3, or if it should be handled in the silent call
handler.
|
|
This enables us to reliably detect if a lchan is part of a silent
call or not.
|
|
* On start the vty code will call the abis_nm method and this
will set the administrative state to unlock/lock
* During startup the BTS will report its state as well and would
possible overwrite the set administrative. We are only going
to update the administrative if it was 0 before. This appears
to work on all of my tests. In case this will not be the case
for others we will have to split the administrative into two
sets one for the BTS and one for the BSC.
|
|
* Add the NACK version to the list
* Dispatch the signal when we receive the message
* Handle it in ipaccess-config by exiting the application
|
|
* Do not issue the restart right aways if we have OML IP or
software load in the queue (hint, we need a real queue of operations
to carry out... with one big state machine)
* Change the signal_data of ipacc ACK/NACK to contain the msg type
and the bts pointer.
* Issue a restart for software load and OML and use the BTS pointer
we got out of the new signal data.

|
* text3 seems to be a version as the text content starts
with a 'v'
* move the sdp_firmware into the ipaccess.h and declare
the function. The headers are returned through a list.
|
|
* Add the signal definition to signal.h
* Dispatch the signal from abis_nm.c
* Handle it in ipaccess-config.c and say we are done with work

this ensures we don't send paging requests to currently inactive transceivers.
|
|
Also, use this new function to dump lchan state on VTY and to
improve readability of RSL log messages.
|
|
This state will help us to differentiate between channels where we have
requested the release, and channels that are actually released.
|
|
|
|
|
|
In many cases we actually want a name / unique ID for the lchan,
not just for the on-air timeslot... especially in SDCCH/8 case,
where 8 SDCCHs share one timeslot...
|
|
When we allocate a channel, we send the RSL CHAN ACT REQ and wait until we get
a CHAN ACT ACK. Only the ACK will change the state, so there is a race where
we allocate that same channel to a different channel request before we get
the ACT ACK.
Introducing a new ACT_REQ state resolves this issue.

The VTY code makes so many allocations that a full report is
simply too long to provide any useful information. So we sub-divide
it in multiple contexts, and report only one level deep at SIGURS1.
We also introduce SIGUSR2 for the full detailed VTY report.
