mainlining shenanigans

The current code copies directly from userspace to ctx->crypto_send, but
doesn't always reinitialize it to 0 on failure. This causes any
subsequent attempt to use this setsockopt to fail because of the
TLS_CRYPTO_INFO_READY check, eventhough crypto_info is not actually
ready.
This should result in a correctly set up socket after the 3rd call, but
currently it does not:
size_t s = sizeof(struct tls12_crypto_info_aes_gcm_128);
struct tls12_crypto_info_aes_gcm_128 crypto_good = {
.info.version = TLS_1_2_VERSION,
.info.cipher_type = TLS_CIPHER_AES_GCM_128,
};
struct tls12_crypto_info_aes_gcm_128 crypto_bad_type = crypto_good;
crypto_bad_type.info.cipher_type = 42;
setsockopt(sock, SOL_TLS, TLS_TX, &crypto_bad_type, s);
setsockopt(sock, SOL_TLS, TLS_TX, &crypto_good, s - 1);
setsockopt(sock, SOL_TLS, TLS_TX, &crypto_good, s);

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
