Francisco Paisana 9c028ab723 removed user_mutex from srsenb::rrc. All that needed to happen was the prach_worker calling add_user from stack thread (done in an earlier PR), and the get_metrics run in the stack thread. I achieved the latter with an extra metrics queue 5 years ago

Andre Puschmann 2edecea33e fix SIB transmission for CA 
Avoid double buffering of SIBs in MAC as this would require one buffer for each CC.
Instead, use byte_buffer managed by RRC that contains packed SIBs to avoid
double memcpy for each SIB tx. Only use MAC provided buffer in error case.

Also avoid MAC calling RLC for each SIB and call RRC directly.

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.

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;

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.
