This makes me think of

openbsc/src/osmo-bsc_mgcp/mgcp_main.c:  srand(time(NULL));
openbsc/src/osmo-bsc/osmo_bsc_main.c: srand(time(NULL));
openbsc/src/osmo-bsc_nat/bsc_nat.c: srand(time(NULL));
openbsc/src/osmo-nitb/bsc_hack.c: srand(time(NULL));

Crypto nightmare.
Are we using those for challenges, actually?
