2020-05-09Use OSMO_FD_READ instead of deprecated BSC_FD_READPau Espin Pedrol1-1/+1
New define is available since libosmocore 1.1.0, and we already require 1.3.0, so no need to update dependenices. Let's change it to avoid people re-using old BSC_FD_READ symbol when copy-pasting somewhere else. Change-Id: I868baf575b77c448b3115701e70d439de89b0fb3

2020-04-14transceiver: get rid of the ctrl threadsEric3-75/+124
There is no need to have n threads handle n ctrl sockets, since they all will immediately respond to commands, so handle them from the existing main osmo select loop. Care must be taken to ensure that calls from within the command handler do not block, or at least don't block too long, which currently is the case.

2020-04-11configure.ac: fix libtool issue with clang and sanitizerEric1-0/+5
As pointed out at https://github.com/libexpat/libexpat/issues/312 libtool does not play nice with clang sanitizer builds at all. For those builds LD shoud be set to clang too (and LDFLAGS needs the sanitizer flags as well), because the clang compiler driver knows how linking to the sanitizer libs works, but then at a later stage libtool fails to actually produce the shared libraries and the build fails. This is fixed by this patch. Addtionally LD_LIBRARY_PATH has no effect on conftest runs during configure time, so the rpath needs to be set to the asan library path to ensure the configure run does not fail due to a missing asan library, i.e.: SANS='-fsanitize=memory -fsanitize-recover=all -shared-libsan' export CC=clang-10 ASANPATH=$(dirname `$CC -print-file-name=libclang_rt.asan-x86_64.so`) export LDFLAGS="-Wl,-rpath,$ASANPATH $SANS $LDFLAGS" Change-Id: If3d9465068b2c654b935fc3d9ab41d799d5e02e8

2020-02-19debug.h: Avoid printing pthread_t typePau Espin Pedrol3-4/+37
Using %lu for pthread_t was wrong on armv7l arch. Even worse, according to pthread_self() man page, pthread_t cannot be assumed to be of a simple type and hence printable: """ POSIX.1 allows an implementation wide freedom in choosing the type used to represent a thread ID; for example, representation using either an arithmetic type or a structure is permitted. """ Let's use gettid() instead. According to glibc documentation: """ The pid_t data type is a signed integer type which is capable of representing a process ID. In the GNU C Library, this is an int. """ It may not be the same on other libc's though, so let's better cast to a long int just in case. Accordign to gettid() man, the libc function was only added recently during glibc 2.30, however the system call has been around for quite some time (linux 2.4.11). Let's accomodate use udner non-glibc or older versions of it by having a direct syscall fallback. Change-Id: I40265fd4c62e550014ba3ff3335ca053c5bc01f2

With current state multi-arfcn can be used (eg. I can place a call between 2 phones using TRX1 and sustain for as long as wanted), but from time to time (around every 20seconds), a burst of Tx packed dropped events from LimeSuite appears.

2020-01-15lms: Store device type specific parameters in one placePau Espin Pedrol4-26/+119
Add an enum containing each supported device type (LimeSDR-USB, LimeSDR-Mini and LimeNet-Micro) plus "unknown", to leave some room for yet-to-come devices to run with some generic parameters without rebuilding osmo-trx. Each device type is assigned a dev_desc structure, and all of them are put in HashMap, similar to what's already done in UHDDevice.cpp. Device type is infered from string provided by LMS_GetDeviceInfo(), as it was already done before in several places. From now on, we only need to parse the string once since we store the device type after first during open time. Later on, more fields will be moved to device-type specific structure, such as Tx timing offset, clock rate, etc. Change-Id: I7658615787c5bc41c365bab9c11733b701ac2ae5

2020-01-13lms: Change radioDevice constructor arg name to avoid masking instance attrPau Espin Pedrol6-9/+9
channel number mangling based on multi-arfcn feature being enabled was moved to generic radioDevice() to reuse code. Hence, the generic parent constructor sets this->chans to 1 if multi-arfcn feature is requested. However, LMSDevice constructor argument had same name as the class instance attribute, taking preference. As a result, if multi-arfcn is enabled in LMSDevice, the generic constructor first sets this->chans=1 but afterwards LMSDEvice constructor keeps calling .resize() with the argument value "chans" instead of using this->chans. Let's rename the argument in all radioDevice child class constructors to avoid potential future bugs in all of them. Change-Id: Id6c837e9133f22783dd92a81dfcc493e51bf2d21

2020-01-07radioInterfaceMulti: Fail to tune on freq not following multi-arfcn restrictionsPau Espin Pedrol2-22/+59
multi-arfcn feature uses a hardcoded disposition of logical channels on a physical channel. Logical channels in the phisical channel are separated by MCBTS_SPACING Hz, that is 4 GSM ARFCNs. As a result, multi-arfcn restricts the TRX ARFCN setup to the following: ARFCN(TRX0)=N, ARFCN(TRX1)=N+1*4, ARFCN(TRX2)=N+2*4, ... Let's make sure radioInterfaceMulti verifies the requested Rx/Tx frequencies for each logical channel over TRXC match the restriction explained above. It will check freq going to be set is indeed separated by MCBTS_SPACING from already set channels, making sure the ARFCN series is consistent. Otherwise, before this patch, one could set in osmo-bsc: ARFCN(TRX0)=N, ARFCN(TRX1)=N+2 and osmo-trx would silently ack the related Rx/TxTUNE TRXC commands, but actually still transmit on ARFCN N+4 instead. As a result, in this scenario TRX!=0 were unusable with multi-arfcn. Related: OS#4207 Change-Id: I2f3d66a611d3a489b3e4d9431994f4ec77b4460f

2019-10-21vty: Simplify filler burst settings and improve help and readability.Alexander Chemeris3-75/+81
In the command line options time, filler table/filer burts settings were a bit difficult to undertand because the number of one-letter settings was limited. Now, with VTY configuration, there is no reason to keep it so difficult. Also, after the previous commit it was no longer posible to enable random 8-PSK filler bursts.

Since libosmocore Id7711893b34263baacac6caf4d489467053131bb, a new API log_enable_multithread() is available which takes care of protecting logging infrastructure from us (and actually does it correctly since we cannot protect internal libosmocore structures from osmo-trx).
