2018-12-07Make EVP_PKEY_asn1_add0() stricter about its inputRichard Levitte
It turns out that the strictness that was implemented in EVP_PKEY_asn1_new() (see Github openssl/openssl#6880) was badly placed for some usages, and that it's better to do this check only when the method is getting registered.

2018-12-06Refactor the computation of API version limitsRichard Levitte
Previously, the API version limit was indicated with a numeric version number. This was "natural" in the pre-3.0.0 because the version was this simple number. With 3.0.0, the version is divided into three separate numbers, and it's only the major number that counts, but we still need to be able to support pre-3.0.0 version limits. Therefore, we allow OPENSSL_API_COMPAT to be defined with a pre-3.0.0 style numeric version number or with a simple major number, i.e. can be defined like this for any application: -D OPENSSL_API_COMPAT=0x10100000L -D OPENSSL_API_COMPAT=3 Since the pre-3.0.0 numerical version numbers are high, it's easy to distinguish between a simple major number and a pre-3.0.0 numerical version number and to thereby support both forms at the same time. Internally, we define the following macros depending on the value of OPENSSL_API_COMPAT: OPENSSL_API_0_9_8 OPENSSL_API_1_0_0 OPENSSL_API_1_1_0 OPENSSL_API_3 They indicate that functions marked for deprecation in the corresponding major release shall not be built if defined.

2018-08-11i2d_ASN1_OBJECT(): allocate memory if the user didn't provide a bufferRichard Levitte
Since 0.9.7, all i2d_ functions were documented to allocate an output buffer if the user didn't provide one, under these conditions (from the 1.0.2 documentation): For OpenSSL 0.9.7 and later if B<*out> is B<NULL> memory will be allocated for a buffer and the encoded data written to it. In this case B<*out> is not incremented and it points to the start of the data just written. i2d_ASN1_OBJECT was found not to do this, and would crash if a NULL output buffer was provided.

2018-04-03Fix a text canonicalisation bug in CMSMatt Caswell
Where a CMS detached signature is used with text content the text goes through a canonicalisation process first prior to signing or verifying a signature. This process strips trailing space at the end of lines, converts line terminators to CRLF and removes additional trailing line terminators at the end of a file. A bug in the canonicalisation process meant that some characters, such as form-feed, were incorrectly treated as whitespace and removed. This is contrary to the specification (RFC5485). This fix could mean that detached text data signed with an earlier version of OpenSSL 1.1.0 may fail to verify using the fixed version, or text data signed with a fixed OpenSSL may fail to verify with an earlier version of OpenSSL 1.1.0. A workaround is to only verify the canonicalised text data and use the "-binary" flag (for the "cms" command line application) or set the SMIME_BINARY/PKCS7_BINARY/CMS_BINARY flags (if using CMS_verify()).

So instead of calling ASN1_item_ex_free(), where we can't pass the embed flag, we call asn1_item_embed_free() directly.
