All callers used the same initialization seed (well, the new viratomictest forgot to look at getpid()); so we might as well make this value automatic. And while it may feel like we are giving up functionality, I documented how to get it back in the unlikely case that you actually need to debug with a fixed pseudo-random sequence. I left that crippled by default, so that a stray environment variable doesn't cause a lack of randomness to become a security issue. * src/util/virrandom.c (virRandomInitialize): Rename... (virRandomOnceInit): ...and make static, with one-shot call. Document how to do fixed-seed debugging. * src/util/virrandom.h (virRandomInitialize): Drop prototype. * src/libvirt_private.syms (virrandom.h): Don't export it. * src/libvirt.c (virInitialize): Adjust caller. * src/lxc/lxc_controller.c (main): Likewise. * src/security/virt-aa-helper.c (main): Likewise. * src/util/iohelper.c (main): Likewise. * tests/seclabeltest.c (main): Likewise. * tests/testutils.c (virtTestMain): Likewise. * tests/viratomictest.c (mymain): Likewise.
