* admin/merge-gnulib (GNULIB_MODULES): Add getrandom. * doc/lispref/text.texi (Format of GnuTLS Cryptography Inputs): Don’t say that iv-auto uses GNUTLS_RND_NONCE. Also, don’t say that it returns the IV’s actual value, as it never has done that. * src/fns.c, src/sysdep.c: Include sys/random.h, for getrandom. * src/fns.c (Fsecure_hash_algorithms): Use getrandom so that this function does not depend on HAVE_GNUTLS3. * src/sysdep.c: Do not include <gnutls/crypto.h>. (random_seed) [HAVE_LRAND48]: Can be long int now. (init_random) [!WINDOWSNT]: Use getrandom syscall instead of opening /dev/urandom, as this works even on GNU/Linux hosts that lack /dev/urandom. Don’t bother with gnutls_rnd as it’s not needed now that we have getrandom.
