If there's anything in the |biosk| stack, the first element is always the input BIO. It should never be freed in this function, so we must take careful steps not to do so inadvertently when freeing the stack. Reviewed-by:

The API used to set what SNI value to send in the ClientHello can also be used on server SSL objects, with undocumented and un-useful behavior. Unfortunately, when generic SSL_METHODs are used, s->server is still set, prior to the start of the handshake, so we cannot prevent this nonsensical usage at the present time. Leave a note to revisit this when ABI-breaking changes are permitted. Reviewed-by:

In particular, adhere to the rule that we must not modify any property of an SSL_SESSION object once it is (or might be) in a session cache. Such modifications are thread-unsafe and have been observed to cause crashes at runtime. To effect this change, standardize on the property that SSL_SESSION->ext.hostname is set only when that SNI value has been negotiated by both parties for use with that session. For session resumption this is trivially the case, so only new handshakes are affected. On the client, the new semantics are that the SSL->ext.hostname is for storing the value configured by the caller, and this value is used when constructing the ClientHello. On the server, SSL->ext.hostname is used to hold the value received from the client. Only if the SNI negotiation is successful will the hostname be stored into the session object; the server can do this after it sends the ServerHello, and the client after it has received and processed the ServerHello. This obviates the need to remove the hostname from the session object in case of failed negotiation (a change that was introduced in commit 9fb6cb81 in order to allow TLS 1.3 early data when SNI was present in the ClientHello but not the session being resumed), which was modifying cached sessions in certain cases. (In TLS 1.3 we always produce a new SSL_SESSION object for new connections, even in the case of resumption, so no TLS 1.3 handshakes were affected.) Reviewed-by:

Originally suggested solution for "Return Of the Hidden Number Problem" is arguably too expensive. While it has marginal impact on slower curves, none to ~6%, optimized implementations suffer real penalties. Most notably sign with P-256 went more than 2 times[!] slower. Instead, just implement constant-time BN_mod_add_quick. Reviewed-by:

By default `ec_scalar_mul_ladder` (which uses the Lopez-Dahab ladder implementation) is used only for (k * Generator) or (k * VariablePoint). ECDSA verification uses (a * Generator + b * VariablePoint): this commit forces the use of `ec_scalar_mul_ladder` also for the ECDSA verification path, while using the default wNAF implementation for any other case. With this commit `ec_scalar_mul_ladder` loses the static attribute, and is added to ec_lcl.h so EC_METHODs can directly use it. While working on a new custom EC_POINTs_mul implementation, I realized that many checks (e.g. all the points being compatible with the given EC_GROUP, creating a temporary BN_CTX if `ctx == NULL`, check for the corner case `scalar == NULL && num == 0`) were duplicated again and again in every single implementation (and actually some implementations lacked some of the tests). I thought that it makes way more sense for those checks that are independent from the actual implementation and should always be done, to be moved in the EC_POINTs_mul wrapper: so this commit also includes these changes.
