Matthew Stevenson fae2982647 [ssl] Fix SSL stack to handle large handshake messages whose length exceeds the BIO buffer size. (#33638 ) There is a bug in the SSL stack that was only partially fixed in #29176: if more than 17kb is written to the BIO buffer, then everything over 17kb will be discarded, and the SSL handshake will fail with a bad record mac error or hang if not enough bytes have arrived yet. It's relatively uncommon to hit this bug, because the TLS handshake messages need to be much larger than normal for you to have a chance of hitting this bug. However, there was a separate bug in the SSL stack (recently fixed in #33558) that causes the ServerHello produced by a gRPC-C++ TLS server to grow linearly in size with the size of the trust bundle; these 2 bugs combined to cause a large number of TLS handshake failures for gRPC-C++ clients talking to gRPC-C++ servers when the server had a large trust bundle. This PR fixes the bug by ensuring that all bytes are successfully written to the BIO buffer. An initial quick fix for this bug was planned in #33611, but abandoned because we were worried about temporarily doubling the memory footprint of all SSL channels. The complexity in this PR is mostly in the test: it is fairly tricky to force gRPC-C++'s SSL stack to generate a sufficiently large ServerHello to trigger this bug.		2 years ago

gRPC core library

This shared library provides all of gRPC's core functionality through a low level API. gRPC libraries for the other languages supported in this repo, are built on top of this shared core library.
