Previoulsy we just had max_early_data which controlled both the value of max early_data that we advertise in tickets *and* the amount of early_data that we are willing to receive from clients. This doesn't work too well in the case where we want to reduce a previously advertised max_early_data value. In that case clients with old, stale tickets may attempt to send us more early data than we are willing to receive. Instead of rejecting the early data we abort the connection if that happens. To avoid this we introduce a new "recv_max_early_data" value. The old max_early_data becomes the value that is advertised in tickets while recv_max_early_data is the maximum we will tolerate from clients. Fixes #6647 Reviewed-by:

The problematic case falls back to a NULL conf which returns the result of getenv(2). If this returns NULL, everything was good. If this returns a string an attempt to convert it to a number is made using the function pointers from conf. This fix uses the strtol(3) function instead, we don't have the configuration settings and this behaves as the default would. Reviewed-by:

1. For every named curve, two "golden" keypair positive tests. 2. Also two "golden" stock ECDH positive tests. 3. For named curves with non-trivial cofactors, additionally two "golden" ECC CDH positive tests. 4. For named curves with non-trivial cofactors, additionally two negative tests. There is some overlap with existing EVP tests, especially for the NIST curves (for example, positive testing ECC CDH KATs for NIST curves). "Golden" here means all the values are independent from OpenSSL's ECC code. I used sage to calculate them. What comes from OpenSSL is: 1. The OIDs (parsed by tooling) 2. The curve parameters (parsing ecparam output with tooling) The values inside the PEMs (private keys, public keys) and shared keys are from sage. The PEMs themselves are the output of asn1parse, with input taken from sage. Reviewed-by:

Currently if you encounter application data while waiting for a close_notify from the peer, and you have called SSL_shutdown() then you will get a -1 return (fatal error) and SSL_ERROR_SYSCALL from SSL_get_error(). This isn't accurate (it should be SSL_ERROR_SSL) and isn't persistent (you can call SSL_shutdown() again and it might then work). We change this into a proper fatal error that is persistent.

This allows operation inside a chroot environment without having the random device present. A new call, RAND_keep_random_devices_open(), has been introduced that can be used to control file descriptor use by the random seed sources. Some seed sources maintain open file descriptors by default, which allows such sources to operate in a chroot(2) jail without the associated device nodes being available. Reviewed-by:
