It was false positive, but one can as well view it as readability issue. Switch even to unsigned indices because % BN_BYTES takes 4-6 instructions with signed dividend vs. 1 (one) with unsigned. Reviewed-by:

"Computationally constant-time" means that it might still leak information about input's length, but only in cases when input is missing complete BN_ULONG limbs. But even then leak is possible only if attacker can observe memory access pattern with limb granularity. Reviewed-by:

To avoid the possibility that someone creates rem.exe, rem.bat or rem.cmd, simply don't use it. In the cases it was used, it was to avoid empty lines, but it turns out that nmake handles those fine, so no harm done. Reviewed-by:

It seems that nmake first tries to run executables on its own, and only pass commands to cmd if that fails. That means it's possible to have nmake run something like 'echo.exe' when the builtin 'echo' command was expected, which might give us unexpected results. To get around this, we create our own echoing script and call it explicitly from the nmake makefile. Fixes #6670 Reviewed-by:

In previous versions of OpenSSL, the documentation for PEM_read_* said: The callback B<must> return the number of characters in the passphrase or 0 if an error occurred. But since c82c3462 , 0 is now treated as a non-error return value. Applications that want to indicate an error need to return -1 instead. Reviewed-by:

This extends the recently added ECDSA signature blinding to blind DSA too. This is based on side channel attacks demonstrated by Keegan Ryan (NCC Group) for ECDSA which are likely to be able to be applied to DSA. Normally, as in ECDSA, during signing the signer calculates: s:= k^-1 * (m + r * priv_key) mod order In ECDSA, the addition operation above provides a sufficient signal for a flush+reload attack to derive the private key given sufficient signature operations. As a mitigation (based on a suggestion from Keegan) we add blinding to the operation so that: s := k^-1 * blind^-1 (blind * m + blind * r * priv_key) mod order Since this attack is a localhost side channel only no CVE is assigned. This commit also tweaks the previous ECDSA blinding so that blinding is only removed at the last possible step. Reviewed-by:
