The code (author) confused MCE_PARAMS_DESC and MCE_NETPARAMS_DESC and
tried to read the MCE name from MCE_NETPARAMS_DESC when in reality it
should come from MCE_PARAMS_DESC. This commit fixes to use the right
array.
In a previous commit, the functionality of handling IPv6 (and DNS names)
as part of the IPv4 was introduced (in IPv4 field for backwards
compatibility). This commit now removes superfluous configuration
fields:
- IPv6: handled by IPv4 field
- active: users can just remove an entry
- preference: not needed
Rewrite sctp_create_new_listener() to use getaddrinfo() to look up
IPv4/IPv6 addresses via a common interface. This allows to use e.g. DNS,
and enables the SCTP library to listen on IPv6 ports.
To support the above, the corresponding message is changed to not take
an IPv4 address on 4 bytes (and separate IPv6), but a single name that
will be resolved via getaddrinfo()
The previous init message used to allow multiple IPv4/IPv6 addresses;
since this is not used anywhere, remove the corresponding functionality.
Modify all uses of this ITTI message to copy te SCTP init bind addr into
ITTI message.
After the last commit, it is not possible to bind on separate interfaces
for F1-C and F1-U. In other words, it is for instance not possible to
have the F1-C on one subnet on one physical interface, and F1-U on
another subnet on another physical interface. This commit introduces a
second option MACRLCs.[0].local_n_address_f1u to allow to bind F1-U on
an alternative address; if it is not specified, the interface of F1-C is
reused.
The above only works for the DU; no corresponding option exists for the
CU. For the CU, use separate CU-CP and CU-UP.
Use it in the CI.
This reverts commit 284116522b.
The problem is that (1) we don't really support multi-homing, but (2) on
some system, if the other IP addresses that the operating system
considers part of the multi-homed connection are HEARTBEAT'ed (e.g.,
docker), they answer with SCTP ABORT, which breaks the entire
connection.
In other words, force single-homing by binding. For F1-U uses, another
option will be introduced that allows to bind to a separate interface
for F1-U (separate from F1-C), if necessary.
Closes#727
- this change simplifies the enum definition and makes it easier
to add, remove, or modify states in the future
- the states are now defined in the NR_UE_L2_STATES macro,
and the enum members are generated automatically from this macro
Prior to this commit, it might happen that the gNB used TDA 0 (Start 0
len 13) for mixed slot, in which case the UE could not send msg3
(because a mixed slot has less than 13 symbols).
