Subject: Don't use buffered fread() to read from DEVRANDOM,
X-Git-Tag: OpenSSL_0_9_5beta2~83
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=1a33f6da8b86c249ba5438bc7e7f840257fac275;p=oweals%2Fopenssl.git

Don't use buffered fread() to read from DEVRANDOM,
because this will drain the entropy pool.
