link_send_packet() has been extended to use for multiple protocols (added UDP,
SCTP after TCP). The test was not update, though, which is fixed in this
commit.
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).
This commit cleans up the link_manager interface:
* don't provide peer_addr/port in create_link_manager() (for TCP/SCTP it is not
needed, so in the UDP case in needs to be set explicitly)
* Make FlexRAN connect again (correct hardcoded address)
* Fix FlexRAN: retain the manager pointer
* Fix FlexRAN: store receive_queue pointer
* the link_manager's sender thread passes the correct peer_addr/port for the
UDP case
* peer_addr is now const
* new_link_udp_server() can bind to address or INADDR_ANY
* socket_udp_receive() happens without a loop
* socket_udp_send() happens without a loop
* sending in two packets (first size, then data) is only performed for TCP,
SCTP, not for UDP anymore (it is unreliable, so we could miss something and
will receive complete garbage)
Try to merge feature-68-enb-agent into develop
develop should be fast-forwarded later to this branch to complete the merge
This code does not compile yet. Among other things:
- the scheduler structure needs to be reworked for FlexRAN
- the config is structured differently. The files enb_config.{c,h} from develop
have been copied in here, the files with merge annotations are in
enb_config.{c,h}.before_merge
- the restart needs to be restructured, since the PHY vars data structure lives
in RC now
Added selection of interfaces through the configuration file with a new block of statements as follows:
FLEXSPLIT_INTERFACES :
{
DU_INTERFACE_NAME_FOR_F1U = "lo";
DU_IPV4_ADDRESS_FOR_F1U = "127.0.0.1/24";
DU_PORT_FOR_F1U = 2210;
CU_INTERFACE_NAME_FOR_F1U = "lo";
CU_IPV4_ADDRESS_FOR_F1U = "127.0.0.1"; //Address to search the DU
CU_PORT_FOR_F1U = 2210;
// One of TCP/UDP/SCTP
F1_U_TRANSPORT_TYPE = "UDP";
};
