This reverts commit edc18749 . The proposed fix is incorrect. It marks the "run_once" code as having finished before it has. The intended semantics of run_once is that no threads should proceed until the code has run exactly once. With this change the "second" thread will think the run_once code has already been run and will continue, even though it is still in progress. This could result in a crash or other incorrect behaviour. Reviewed-by:

In order to minimize dependency on assembler version a number of post-SSE2 instructions are encoded manually. But in order to simplify the procedure only register operands are considered. Non-register operands are passed down to assembler. Module in question uses pshufb with memory operands, and old [GNU] assembler can't handle it. Fortunately in this case it's possible skip just the problematic segment without skipping SSSE3 support altogether. Reviewed-by:

For consistency, it's better to use the perl that was specified to Configure last time it was called. Use case: perl v5.8.8 was first along $PATH, perl v5.22.2 was available and specified as: PERL=/opt/local/bin/perl ./config. When make wanted to reconfigure and called './Configure reconf', configuration broke down, complaining about a perl that's too old. Reviewed-by:

PKCS #1 v2.0 is the name of a document which specifies an algorithm RSASSA-PKCS1-v1_5, often referred to as "PKCS #1 v1.5" after an earlier document which specified it. This gets further confusing because the document PKCS #1 v2.1 specifies two signature algorithms, RSASSA-PKCS1-v1_5 and RSASSA-PSS. RSA_sign implements RSASSA-PKCS1-v1_5. Refer to the document using the RFC number which is easier to find anyway, and refer to the algorithm by its name. Reviewed-by:

RFC 3447, section 8.2.2, steps 3 and 4 states that verifiers must encode the DigestInfo struct and then compare the result against the public key operation result. This implies that one and only one encoding is legal. OpenSSL instead parses with crypto/asn1, then checks that the encoding round-trips, and allows some variations for the parameter. Sufficient laxness in this area can allow signature forgeries, as described in https://www.imperialviolet.org/2014/09/26/pkcs1.html Although there aren't known attacks against OpenSSL's current scheme, this change makes OpenSSL implement the algorithm as specified. This avoids the uncertainty and, more importantly, helps grow a healthy ecosystem. Laxness beyond the spec, particularly in implementations which enjoy wide use, risks harm to the ecosystem for all. A signature producer which only tests against OpenSSL may not notice bugs and accidentally become widely deployed. Thus implementations have a responsibility to honor the specification as tightly as is practical. In some cases, the damage is permanent and the spec deviation and security risk becomes a tax all implementors must forever pay, but not here. Both BoringSSL and Go successfully implemented and deployed RSASSA-PKCS1-v1_5 as specified since their respective beginnings, so this change should be compatible enough to pin down in future OpenSSL releases. See also https://tools.ietf.org/html/draft-thomson-postel-was-wrong-00 As a bonus, by not having to deal with sign/verify differences, this version is also somewhat clearer. It also more consistently enforces digest lengths in the verify_recover codepath. The NID_md5_sha1 codepath wasn't quite doing this right. Reviewed-by:

This partially reverts commit c636c1c4 . It also tweaks the documentation and comments in this area. On the client side the documented interface for SSL_CTX_set_verify()/SSL_set_verify() is that setting the flag SSL_VERIFY_PEER causes verfication of the server certificate to take place. Previously what was implemented was that if *any* flag was set then verification would take place. The above commit improved the semantics to be as per the documented interface. However, we have had a report of at least one application where an application was incorrectly using the interface and used *only* SSL_VERIFY_FAIL_IF_NO_PEER_CERT on the client side. In OpenSSL prior to the above commit this still caused verification of the server certificate to take place. After this commit the application silently failed to verify the server certificate. Ideally SSL_CTX_set_verify()/SSL_set_verify() could be modified to indicate if invalid flags were being used. However these are void functions! The simplest short term solution is to revert to the previous behaviour which at least means we "fail closed" rather than "fail open". Thanks to Cory Benfield for reporting this issue. Reviewed-by:

We read it later in grow_init_buf(). If CCS is the first thing received in a flight, then it will use the init_msg from the last flight we received. If the init_buf has been grown in the meantime then it will point to some arbitrary other memory location. This is likely to result in grow_init_buf() attempting to grow to some excessively large amount which is likely to fail. In practice this should never happen because the only time we receive a CCS as the first thing in a flight is in an abbreviated handshake. None of the preceding messages from the server flight would be large enough to trigger this. Reviewed-by:
