* Move client parsing of ServerHello extensions into new frameworkMatt Caswell2016-12-081-57/+0

* Refactor ClientHello extension parsingMatt Caswell2016-12-081-67/+0
| | | | | | | | | | | | | | | | | This builds on the work started in 1ab3836b3 and extends is so that each extension has its own identified parsing functions, as well as an allowed context identifying which messages and protocols it is relevant for. Subsequent commits will do a similar job for the ServerHello extensions. This will enable us to have common functions for processing extension blocks no matter which of the multiple messages they are received from. In TLSv1.3 a number of different messages have extension blocks, and some extensions have moved from one message to another when compared to TLSv1.2. Perl changes reviewed by Richard Levitte.

| | | | | | | | When setting a new SRTP connection profile using SSL_CTX_set_tlsext_use_srtp() or SSL_set_tlsext_use_srtp() we should free any existing profile first to avoid a memory leak. Reviewed-by: Kurt Roeckx <kurt@openssl.org>

* Include <openssl/foo.h> instead of "foo.h"Geoff Thorpe2014-12-081-1/+0
| | | | | | | | | | | | Exported headers shouldn't be included as "foo.h" by code from the same module, it should only do so for module-internal headers. This is because the symlinking of exported headers (from include/openssl/foo.h to crypto/foo/foo.h) is being removed, and the exported headers are being moved to the include/openssl/ directory instead.
