-Subject: [PATCH 1/2] Fix DSA, preserve BN_FLG_CONSTTIME
-
-Operations in the DSA signing algorithm should run in constant time in
-order to avoid side channel attacks. A flaw in the OpenSSL DSA
-implementation means that a non-constant time codepath is followed for
-certain operations. This has been demonstrated through a cache-timing
-attack to be sufficient for an attacker to recover the private DSA key.

-Subject: [PATCH 2/2] More fix DSA, preserve BN_FLG_CONSTTIME
-
-The previous "fix" still left "k" exposed to constant time problems in
-the later BN_mod_inverse() call. Ensure both k and kq have the
-BN_FLG_CONSTTIME flag set at the earliest opportunity after creation.
