Robert Schmidt 42713b95fc Configure complete PDCP in lte-(ue)softmodem 
* Instead of partly initializing in read_config_and_init(), everything of
  PDCP is initialized in main() of lte-softmodem
* Omit RC.rrc access in RRU through checking of RC.nb_inst > 0
* Includes FlexRAN, i.e. do not start FlexRAN in RRU
* Function pointers to PDCP functions have to be set explicitly (avoid
  confusion of multiply setting function pointers)

Robert Schmidt bbedd315e7 Correctly link lte-uesoftmodem(-nos1) (hack) 
Although not used in the UE, we currently need to link the F1 library into it.
This is because we do not define ASN_DISABLE_OER_SUPPORT (otherwise, F1 has
compilation problems). In this case, some functions are apparently not
correctly defined, giving linker errors in the UE. Linking F1 in solves the
problem.

This is a hack. It would be better to be able to define ASN_DISABLE_OER_SUPPORT
and have no compilation errors or compile everything with
ASN_DISABLE_OER_SUPPORT except F1. I did not do this because I did not find
another way than add target_compile_definitions() to every target except F1
which adds many lines just so that one target (F1 ASN.1) compiles correctly (in
other words, F1 needs to be fixed).

commit.

Robert Schmidt 822f9849a2 Stop CU's PROTO_AGENT when DU disconnects 
This adds an exit flag as well as the proto_agent_async_msg_recv_unlock()
function to unlock and release the proto_agent worker thread correctly.
 2019-02-07 18:00:20 +01:00
Robert Schmidt beec74b01a Correctly stop link_manager sender and receiver threads 
This changes the destroy_link_manager() function to:
* call a new function message_get_unlock() to unlock the sending thread from
  its blocking message_get()
* calls pthread_cancel() on the receiving thread, because this unlocks any
  blocking read from a file descriptor

The same message_get_unlock() function has been added ringbuffer_queue to keep
the interfaces the same (it does nothing, because ringbuffer_queue is
non-blocking).

Robert Schmidt d9d6ce374f Perform S1 UE Context Release Complete after corresponding F1 message 
This commits isolates the S1 UE Ctxt Rel Complete and GTP Tunnel Delete
Requests in functions and calls these function in the original place
(rrc_rx_tx()). The same functions are then used in the F1 UE Ctxt Rel
Complete handler to perform the same functionality, i.e. forward the UE
Ctxt Rel Complete message to the MME and free outstanding resources (RRC
context, GTP tunnels, S1 context).

Robert Schmidt 29f23e161e Fix socket type to IPv4 in case of no-multi usage 
sctp_create_new_listener() takes a parameter server_type which is NOT
the IP version but whether it is an SCTP multihoming server. There was a
bug that when multihoming is not wanted, it created an IPv6 socket
instead of IPv4. This commit fixes this.

IPv6 is not supported yet.

Robert Schmidt 6bd69d6eaa Leave OER support in asn1c enabled 
OER can be disable with the switch -DASN_DISABLE_OER_SUPPORT. In F1AP,
disabling OER leads to a typedef void a_type; leading to lots of compilation
errors because of illegal void variable declarations. This commit leaves OER
support enabled, avoiding this error.
