Commit 56fb454d backported the DSA reallocation fix to 1.1.0, however a code block that has multiple statements in 1.1.1+ only has a `goto` in 1.1.0 so introduces a brace that causes a compile failure. CLA:trivial Reviewed-by:

Avoid a timing attack that leaks information via a side channel that triggers when a BN is resized. Increasing the size of the BNs prior to doing anything with them suppresses the attack. Thanks due to Samuel Weiser for finding and locating this. Reviewed-by:

There is a side channel attack against the division used to calculate one of the modulo inverses in the DSA algorithm. This change takes advantage of the primality of the modulo and Fermat's little theorem to calculate the inverse without leaking information. Thanks to Samuel Weiser for finding and reporting this.

Previously, the RNG sets `initialized=1` after the first call to RAND_poll(), although its criterion for being initialized actually is whether condition `entropy >= ENTROPY_NEEDED` is true. This commit now assigns `initialized=(entropy >= ENTROPY_NEEDED)`, which has the effect that on the next call, RAND_poll() will be called again, if it previously failed to obtain enough entropy.

Also, some readers of the code find starting the count at 1 for EE cert confusing (since RFC5280 counts only non-self-issued intermediate CAs, but we also counted the leaf). Therefore, never count the EE cert, and adjust the path length comparison accordinly. This may be more clear to the reader. Reviewed-by:

At the bottom of https://tools.ietf.org/html/rfc5280#page-12 and top of https://tools.ietf.org/html/rfc5280#page-13 (last paragraph of above https://tools.ietf.org/html/rfc5280#section-3.3), we see: This specification covers two classes of certificates: CA certificates and end entity certificates. CA certificates may be further divided into three classes: cross-certificates, self-issued certificates, and self-signed certificates. Cross-certificates are CA certificates in which the issuer and subject are different entities. Cross-certificates describe a trust relationship between the two CAs. Self-issued certificates are CA certificates in which the issuer and subject are the same entity. Self-issued certificates are generated to support changes in policy or operations. Self- signed certificates are self-issued certificates where the digital signature may be verified by the public key bound into the certificate. Self-signed certificates are used to convey a public key for use to begin certification paths. End entity certificates are issued to subjects that are not authorized to issue certificates. that the term "self-issued" is only applicable to CAs, not end-entity certificates. In https://tools.ietf.org/html/rfc5280#section-4.2.1.9 the description of path length constraints says: The pathLenConstraint field is meaningful only if the cA boolean is asserted and the key usage extension, if present, asserts the keyCertSign bit (Section 4.2.1.3). In this case, it gives the maximum number of non-self-issued intermediate certificates that may follow this certificate in a valid certification path. (Note: The last certificate in the certification path is not an intermediate certificate, and is not included in this limit. Usually, the last certificate is an end entity certificate, but it can be a CA certificate.) This makes it clear that exclusion of self-issued certificates from the path length count applies only to some *intermediate* CA certificates. A leaf certificate whether it has identical issuer and subject or whether it is a CA or not is never part of the intermediate certificate count. The handling of all leaf certificates must be the same, in the case of our code to post-increment the path count by 1, so that we ultimately reach a non-self-issued intermediate it will be the first one (not zeroth) in the chain of intermediates.

Historically (i.e., OpenSSL 1.0.x), the openssl applications would allow for empty subject attributes to be passed via the -subj argument, e.g., `opensl req -subj '/CN=joe/O=/OU=local' ...`. Commit db4c08f0 applied a badly needed rewrite to the parse_name() helper function that parses these strings, but in the process dropped a check that would skip attributes with no associated value. As a result, such strings are now treated as hard errors and the operation fails. Restore the check to skip empty attribute values and restore the historical behavior. Document the behavior for empty subject attribute values in the corresponding applications' manual pages. (cherry picked from commit 3d362f19) (cherry picked from commit a7ee1ef6 ) Reviewed-by:

This commit implements coordinate blinding, i.e., it randomizes the representative of an elliptic curve point in its equivalence class, for prime curves implemented through EC_GFp_simple_method, EC_GFp_mont_method, and EC_GFp_nist_method. This commit is derived from the patch https://marc.info/?l=openssl-dev&m=131194808413635 by Billy Brumley. Coordinate blinding is a generally useful side-channel countermeasure and is (mostly) free. The function itself takes a few field multiplicationss, but is usually only necessary at the beginning of a scalar multiplication (as implemented in the patch). When used this way, it makes the values that variables take (i.e., field elements in an algorithm state) unpredictable. For instance, this mitigates chosen EC point side-channel attacks for settings such as ECDH and EC private key decryption, for the aforementioned curves. For EC_METHODs using different coordinate representations this commit does nothing, but the corresponding coordinate blinding function can be easily added in the future to extend these changes to such curves.

This is a backport of #6608 to 1.1.0. 1. For every named curve, two "golden" keypair positive tests. 2. Also two "golden" stock ECDH positive tests. 3. For named curves with non-trivial cofactors, additionally two "golden" ECC CDH positive tests. 4. For named curves with non-trivial cofactors, additionally two negative tests. There is some overlap with existing EVP tests, especially for the NIST curves (for example, positive testing ECC CDH KATs for NIST curves). "Golden" here means all the values are independent from OpenSSL's ECC code. I used sage to calculate them. What comes from OpenSSL is: 1. The OIDs (parsed by tooling) 2. The curve parameters (parsing ecparam output with tooling) The values inside the PEMs (private keys, public keys) and shared keys are from sage. The PEMs themselves are the output of asn1parse, with input taken from sage. (cherry picked from commit 249330de ) Reviewed-by:

`RSA_free()` and friends are called in case of error from `RSA_new_method(ENGINE *e)` (or the respective equivalent functions). For the rest of the description I'll talk about `RSA_*`, but the same applies for the equivalent `DSA_free()`, `DH_free()`, `EC_KEY_free()`. If `RSA_new_method()` fails because the engine does not implement the required method, when `RSA_free(RSA *r)` is called, `r->meth == NULL` and a segfault happens while checking if `r->meth->finish` is defined. This commit fixes this issue by ensuring that `r->meth` is not NULL before dereferencing it to check for `r->meth->finish`. Fixes #7102 . Reviewed-by:
