2019-08-26Transceiver: exit process when BTS drops connectionPau Espin Pedrol2-30/+53
We don't want to keep osmo-trx running in a started state once the BTS controlling it becomes unavailable. If a socket towards the BTS fails, it means the BTS is gone and the best thing to do is to stop the process (alternatively we could go back to stopped state instead, and wait for BTS to re-connect, fur so far this action is good enough).

2019-08-26Transceiver: Fix idle ul burst indications being droppedPau Espin Pedrol1-1/+2
pullRadioVector() should return true on idle frames because those indications may be handled by upper layers (TRXDv1). Clarify return code in function documentation. Change-Id: If592ed1c04cf7e995f656b313f60edd4d40d1bfd

2019-08-26Transceiver: fix segfault during init if IP addr binding failsPau Espin Pedrol1-3/+5
If osmo-trx is started and IP addr binding fails (ie because the IP address is not assigned in the system), it will try to access a heap-allocated Thread instance which was not initialized (because init() function returned earlier).

2019-08-21Drop old setPriority related codePau Espin Pedrol8-32/+0
This code is not needed anymore since we are setting SCHED_RR scheduler with a real time priority in main thread during startup, so all threads will inherit same rt priority, which should be enough to keep the process working reliably even on high system loads (from non rt processes). osmo-trx was tested to be reliable during test with stress-ng as explained in related ticket below.

2019-08-14osmo-trx: log to stderr on signal receivedPau Espin Pedrol1-2/+2
Since osmo-trx it's a big multithreaded process and shutdown sequence can be complex, better use stderr to log signal received events to make sure log is outputted straigh away and not buffered. In general stdout is usually line-buffered, but buffering strategy can be more conservative if output is for instance redirected to a file. Change-Id: I70ba86919d1f7df41ef3db4916317d27697a025c
2019-08-07Transceiver: Add missing include netinet/in.hPau Espin Pedrol1-0/+1
Previous commit started using IPPROTO_UDP without including required include. Newer versions of libosmocore's osmocom/core/socket.h include that header so the define is present, but older versions of libosmocore (such as 0.12.0) don't, so let's include it explicitly (the correct thing to do).

2019-08-01lms: Drop rx_underruns rate ctr, add tx_drop_* rate ctrPau Espin Pedrol2-28/+61
After discussion in [1] and further look at the code, it became obvios rx_underrun events are not happening in general for any SDR (don't exist), so let's drop that counter. Instead, add Tx Dropped Packet counters, which were not accounted prior to this commit.

2019-07-29radioInterface: Clarify how underruns are handled driving a radioDevicePau Espin Pedrol1-1/+3
The underrun parameter in radioDevice's readSamples() is not a "Rx Underrun" event, but rather it's used to retrieve a "Tx Underrun" which on some SDRs (like USRP1) seems to be (so far) available only at readSamples() times. Thus, underrun parameter for both readSamples() and writeSamples() is actually flagging the same event, and should be ORed in pushBuffer() as it's already done in pullBuffer(). Otherwise if implementation is setting the underrun pointer to false, it could erase the flag being marked by the counterpart function before isUnderrun() is called (which is the one responsible to clear the flag).

2019-07-23Transceiver: Clean up code passing parameters to threadsPau Espin Pedrol2-45/+37
TransceiverChannel naming was misleading there. It's simply a data type used to pass 2 parameters through the void* of the thread entry function, so let's clearly specify is a storage for thread params. Furthermore, we don't need a full C++ class for that, let's simply use a struct. Change-Id: I6e3898a8a66520cc5b2a7df9b9ae01b0b272387f
2019-07-23Transceiver: Store TRXD version per channelPau Espin Pedrol2-8/+9
The setting is negotiatied by osmo-bts-trx on each channel, so let's keep and use state per channel instead of overwriting the state from different channels. Take the chance to change related log lines to also print the channel number. Change-Id: If9cf95e89d38d0155ab48b8c0977ca5f381c2aad

2019-07-19Transceiver: Initialize mExtRACH in constructorPau Espin Pedrol1-1/+2
Doing so should make Coverity happy: >>> CID 200212: Uninitialized members (UNINIT_CTOR) >>> Non-static class member "mExtRACH" is not initialized in this constructor nor in any functions that it calls. The current status is actually harmless since the field will be set during init() time, and the variable is never used before init() is called.
