Andre Puschmann 9e113f8b27 pdcp: allow to configure security for rx/tx seperately 
previously PDCP security (integrity and ciphering) could only
be enabled for both Rx and Tx at the same time.

this, however, caused an issue during the conformance testing in which,
in TC_8_2_1_1() for example, the eNB sends a SecModeCommand and a
RRC Reconfiguration in the same MAC TB. In this case, the eNB
needs to be able to enable DL security right after sending the SecModeCmd
in order to send the RRCReconfig encrypted. However, enabling UL security needs
to be postponed until after the SecModeComplete is received.

This patch allows to enable PDCP security for rx/tx independently if
that is needed. The default way is like before, enabling it for tx/rx at
the same time.

Pau Espin Pedrol 4949df257e Proper shutdown on SIGHUP 
If a process exits and has a controlling terminal, everything under
it gets a SIGHUP by the kernel. That's the case for instance when
running a srsUE over ssh with some specific parameters. As a result,
when the ssh client is killed, SIGHUP is sent to srsUE, which will be
killed immediatelly without proper release, which means in turn that log
buffers are not flushed.
Let's do proper shutdown when SIGHUP is received so that everyone can
get log files.

Andre Puschmann ed179fd311 timers: rename value() to time_elapsed() 
this seems to be better readable than value() since
we've sometimes confused it with the timeout value
 5 years ago
Andre Puschmann a32d4ebf59 move PRACH config check into cfg parser 5 years ago
Andre Puschmann 179fd394b2 enb: add SRB2+DRB1 to scheduler AFTER receiving Reconfig Complete 
this commit fixes and issue where, after receiving paging and the resulting
PRACH from the UE, the eNB would create DRB1 and already schedule DL traffic
on this bearer. However, since the UE has not received the reconfig message
yet, the DL traffic is dropped since DRB1 isn't set up yet.

the commit also does not reset the BSR state of the bearer inside MAC since
this caused to a stall of the received DL PDU. The value would initially be set to
a non-zero value (after receiving the DL PDU from EPC). But when the bearer
was (re-)introduced to MAC, it would reset the BSR to zero, and, since
MAC never polls RLC, the PDU wasn't sent down until the next PDU arrives
and sets the BSR to a non-zero value again.

Andre Puschmann ad304207b3 patch PRACH offset parameter for 6 PRB 
the 6 PRB eNB requires a different PRACH offset than the default
value of 2 in the SIB1 example. In order to avoid having
to use a separate SIB config with just a single different value,
the patch patches the value to the only right configuration, if it's wrong.
It continues operation but still issues a warning so the user
can change it in the config.

Andre Puschmann fef6893ce4 make user activity handling independent of system time 
this commit removes the getsystime() call from the activity handling.
it uses a single timer per UE to handle its activity.

three different timer values exist. one for the Msg3 reception. This
is like before and is quite low to quickly remove fake UEs from the
RRC. The second is a generic value (set to 1s for now) that covers
the entire UE configuration phase where multiple messages are sent
back and forth until the UE is fully set up and the default
bearer runs. From there on, the UE inactivity timer is used which
may be much bigger than 1s.

Andre Puschmann 6ec573987a remove default value for 'blocking' param from pdcp::write_sdu() 
there were two defaults and one was shadowing the other. This
commit removes both defaults and uses blocking-mode for RRC

mode by default. We have to review the eNB's RRC perhaps and use blocking
there too and non-blocking only for data plane

Harald Welte 2e426948fe [ENB] Add CFSB support 
This commit introduces CSFB (circuit switched fall-back) capabilities to
srsLTE.  Actually, all the eNB has to do is to send a
RrcConnectionRelease with the RedirectedCarrierInfo IE.

The MME triggers this by the S1AP CS Fallback Indicator IE, which may
be present either in the Initial Context Setup Requst or in the
UE Context Modification Request.

As srsLTE has no support for the UE Context Modification Request at all
yet (!), basic support for this message is introduced in this patch.

Both Mobile Originated and Mobile Terminated CSFB with a coupel of
different UE models have been verified using this patch in a setup
consisting of srsENB attached to an undisclosed EPC connected via SGsAP
to a complete  Osmocom 2G network.

Harald Welte 756374419f SRSENB: Add SIB7 (GERAN neighbor) support 
This adds the required missing bits to the eNB config file parser
to enable minimalistic support of parsing SIB7 configuration.

SIB7 contains GERAN (GSM) neighbor cell information, which is important
if you are operating a combined 2G+4G netowrk and want to assist the UEs
to reselect GSM cells once they move out of LTE coverage.

An example SIB7 section looks as follows:

sib7 = {
    t_resel_geran = 1;
    carrier_freqs_info_list =
    (
        {
            cell_resel_prio = 0;
            ncc_permitted = 255;
            q_rx_lev_min = 0;
            thresh_x_high = 7;
            thresh_x_low = 7;

            start_arfcn = 871;
            band_ind = "dcs1800";
            explicit_list_of_arfcns = ( 873, 875, 877 );
        }

Harald Welte 844994f2cd [ENB] Fix enabling of MAC pcap file 
when using

[pcap]
enable = true
filename = /tmp/enb.pcap

in enb.conf, there is no pcap file created.

The problem is somewhere in the way how arguments are handled.
pcap.enable is properly parsed into args.pcap.  However, later on,
lte_stack->init(args.stack, rrc_cfg, lte_phy.get()) only passes
args.stack down the road, not args.pcap.  enb_stack_lte::init() then
basically uses args.stack.pcap and not args.pcap, and the latter appears
always false.

Let's remove pcap_args_t from all_args and only use the instance in
stack_args_t.

components which are not initialzized yet, and logging therefore doesn't work.
the log object is know during contruction time and therefore can be passed
in as soon as possible.
