Subject: Check RAND_bytes() return value, fail when getting random fails.
X-Git-Tag: release-1.0.24~10
X-Git-Url: https://tinc-vpn.org/git/browse?p=tinc;a=commitdiff_plain;h=6685f2c8afc4775c3656dccc5a37286c01c0e854;hp=6685f2c8afc4775c3656dccc5a37286c01c0e854

Check RAND_bytes() return value, fail when getting random fails.

When RAND_bytes() does not return success, the buffer contents cannot be
used. This patch makes sure the return code is checked, and the connection
fails when keys or challenges cannot be trusted.
