this is an extension to the currently available security
configuration and activation methods provided by PDCP.
The new call allows to specify a Rx and Tx SN after which the
entire security config, i.e. integrity and ciphering, should
be enabled.
this is mainly required for the PDCP entity of the conformance
testing SS but could potentially also be used by the eNB
to enable security for PDCP after sending the SecModeCommand
for example.
the extra call was added to not break the existing API.
This commit implements support for the CLOSE_UE_TEST_LOOP message.
Currently the mode is not saved and looping the data is not implemented.
Only the *_COMPLETE message is sent back as a response.
it seems that exit() causes problems when threads couldn't be stopped
properly, which is the reason why we have to call alarm() in the first place.
therefore, send a SIGKILL to our process and make sure we don't leave any
zombie threads running.
we agreed to print the error message but still patch the values to
work for 6 PRBs. Since there is only one option there is not
configuration ambiguity.
this is according to 24.301 Sec 4.4.3.3 which says the receiver
should use the sequence number included in the received message
rather a local estimate
First of all, with this the NAS conformance tests pass with ciphering and
integrity turned on. Before only integrity was working.
Mainly the NAS was applying the integrity protection and/or ciphering
incorrectly because it wasn't taking the secuirty status of the PDUs
into account. Some where already correct, some not. The patch
streamlines the handling for all outgoing messages.
during deinit of the UE/eNB it could happen that the log_ptr
was already set to null but the stack thread was still accessing
it through log_h->info()
i've moved the old macro into a new header and used as as much
as possible. there are still places in the code where similar
macros are used but we would need to change the variable name
to replace them
previously the NAS would cancel a attach request procedure if the PLMN
is already selected. PLMN selection, however, in not necessarily happening
before requesting RRC to establish a connection.
this is to better differentiate from "send_attach_request" that
only packs and send the actual attach request message. The
entire attach procedure may include PLMN search, etc.
