BUF_memdup tries to avoid mallocing zero bytes (and thus unduly
returning an error for a NULL return value) by testing whether the input
buffer is NULL. This goes back to the original OpenSSL code.
However, when |ext_npn_parse_serverhello| tries to use |BUF_memdup| to
copy an NPN value returned by a callback, some callbacks just set the
output /length/ to zero to indicate an empty value. Thus, when
|BUF_memdup| tests the pointer, it's an uninitialised value and MSan
throws an error.
Since passing a NULL pointer to |BUF_memdup| better imply that the
length is zero, while the reverse empirically isn't true, testing the
length seems safer.

Putting it at the top was probably a mistake? Even though SSL_CIPHER
(like SSL_SESSION) doesn't depend on SSL, if you're reading through the
header, SSL_CTX and SSL are the most important types. You could even use
the library without touch cipher suite configs if you don't care since
the default is decently reasonable, though it does include a lot of
ciphers. (Hard to change that if we wanted to because DEFAULT is often
used somewhat like ALL and then people subtract from it.)

The cipher suite rules could also be anchored on SSL_TXT_* if desired. I
currently documented them in prose largely because SSL_TXT_* also
defines protocol version strings and those are weird; SSL_TXT_TLSV1_1
isn't even a cipher rule. (And, in fact, those are the only SSL_TXT_*
macros that we can't blindly remove. I found some code that #ifdef's the
version SSL_TXT_* macros to decide if version-locked SSL_METHODs are
available.)
Also they clutter the header. I was thinking maybe we should dump a lot
of the random constants into a separate undocumented header or perhaps
just unexport them.
I'm slightly torn on this though and could easily be convinced in the
other direction. (Playing devil's advocate, anchoring on SSL_TXT_* means
we're less likely to forget to document one so long as adding a
SSL_TXT_* macro is the convention.)

latter by changing both it and d2i_AutoPrivateKey to explicitly hit the

The IUF functions were added for PEM and internally are very lenient to
whitespace and include other PEM-specific behaviors (notably they treat
hyphens as EOF). They also decode a ton of invalid input (see upstream's
RT #3757).
Upstream has a rewrite with tests that resolves the latter issue which
we should review and import. But this is still a very PEM-specific
interface. As this code has basically no callers outside the PEM code
(and any such callers likely don't want a PEM-specific API), it's
probably not worth the trouble to massage this and PEM into a strict IUF
base64 API with PEM whitespace and hyphen bits outside. Just deprecate
it all and leave it in a corner.

hook in SSL_PRIVATE_KEY_METHOD to limit such keys to SHA1. However,
detecting those keys was a heuristic, so some SHA256-capable keys
authenticating to SHA256-only servers regressed in the switch to
BoringSSL. Replace this mechanism with an API to configure digest
preference order. This way heuristically-detected SHA1-only keys may be
configured by Chromium as SHA1-preferring rather than SHA1-requiring.
In doing so, clean up the shared_sigalgs machinery somewhat.
