msc: The udt_relay could be implemented with the normal cellmgr now
...
Simplify the code and remove the standalone udt_relay application,
the job can be done with cellmgr_ng. This will happen after we have
settled for a new config file format.

msc: In forward_only mode never ask any of the connection tracking code
...
For the forward only code we never want to go through the other
cases, make sure to always return.

bsc: Move the BSC<->MSC variables to a new struct.
...
Move the MSC related information out of the bsc_data and update
the code to use this BSC configuration. This is greatly cleaning
up the code and in theory there might now be two BSC and two MSCs
that one application can handle (minus the missing VTY config)

stp: Add code that allows to inject messages on any linkset
...
This can be useful to test out certain messages without having
any of the linksets be fully connected. It is not possible to
get the result. In the future this code should reply with an
M2UA error message if something went wrong.

udp: Use link up/down signals from the MIB for the link
...
The mib was patched to send link up/down in case of failures,
only put a link service when the MIB tells us the link is
up, the failure case should only happen for remote links
failing. We will reset and go through link alignment.

sctp: Close the socket if we get <= 0 as a result for sctp_rcvmsg

The manpage says that -1 is the indication for error but on 2.6.12
we just ended up in a infinite loop as select shows the socket as
readable but a recvmsg does not give any data.

udp: Create a SNMP session per UDP
...
We do not have the multiple callbacks from SNMP under control
and we can only save the last request if the SNMP Session is
inside the link. This is mostly a workaround for Net-SNMP and
the missing documentation on the async functionality.

mtp: Implement VTY routines to block,unblock,reset a link

This can help in link management and reconfiguration of a
link at runtime. It is also a good engineering mode for
multiple linksets.
2011-01-24 16:14:25 +01:00
ea5ce23d72
mtp: Make it possible to block a link.
...
The semantic of a block is to take the physical
link down, call mtp_link_down and to make sure
that the link remains down and no packets are
forwarded there. The unblock call will reset the
link and this should get it back into operation
again.

msc: Fix crash due pong timeout started from a msc reset
...
This is fixing a crash that is caused by the MTP link going
down/up and the main routines asking to send a reset to the
MSC. The sending of a reset is triggering the ping/pong
timeouts. In case there is no MSC connection we could crash.

Rename link_data to mtp_link and move it into the mtp_data header
