( https://gerrit.osmocom.org/c/libosmocore/+/27024 ) Change subject: log: socket.c: rather use the osmo_sockaddr_str _FMT ...................................................................... log: socket.c: rather use the osmo_sockaddr_str _FMT The OSMO_SOCKADDR_STR_FMT() and _ARGS() macros properly place square braces around IPv6 addresses, so that the port nr is clearly distinguishable. before: 1:2::3:4:5 after: [1:2::3:4]:5 When using a struct reference, the macro resolves to '(&sastr) ? .. : ..', which the compiler complains about as "condition is always true". Shim around that error with a pointer variable. I considered using osmo_sockaddr_to_str_c() instead, but here in socket.c we cannot assume that osmo_select_main_ctx() is being used and hence can't just use OTC_SELECT for log string composition. The struct osmo_sockaddr_str is a string representation in a local variable, and hence doesn't need talloc for log strings. I considered adding log_check_level() around the log string conversion, but since all of these instances are on LOGL_ERROR, I didn't bother.
