OpenSSL upstream did a bulk reformat. We still have some files that have the old OpenSSL style and this makes applying patches to them more manual, and thus more error-prone, than it should be. This change is the result of running util/openssl-format-source -v -c . in the enumerated directories. A few files were in BoringSSL style and have not been touched. This change should be formatting only; no semantic difference.

|
|
* X509_REQ_INFO is handled in an unusual way to get round invalid encodings.
|
|
* Some broken certificate requests don't encode the attributes field if it
|
|
* is empty. This is in violation of PKCS#10 but we need to tolerate it. We
|
|
* do this by making the attributes field OPTIONAL then using the callback to
|
|
* initialise it to an empty STACK. This means that the field will be
|
|
* correctly encoded unless we NULL out the field. As a result we no longer
|
|
* need the req_kludge field because the information is now contained in the
|
|
* attributes field: 1. If it is NULL then it's the invalid omission. 2. If
|
|
* it is empty it is the correct encoding. 3. If it is not empty then some
|
|
* attributes are present.
