lib/libcrypto/bn: bn_exp.c
Log message:
Correctly reduce negative inpot to BN_mod_exp2_mont()
Negative bases could result in a negative modulus being returned. This is
not strictly speaking incorrect but slightly surprising. This is all a
consequence of the shortcut of defining BN_mod() as a macro using BN_div().
Fixes ossfuzz #55997
