      Tighten session ticket handling · d663df23

      Tighten client-side session ticket handling during renegotiation:
      ensure that the client only accepts a session ticket if the server sends
      the extension anew in the ServerHello. Previously, a TLS client would
      reuse the old extension state and thus accept a session ticket if one was
      announced in the initial ServerHello.

      Fix DTLS retransmission from previous session. · 20b82b51
      Dr. Stephen Henson authored
      For DTLS we might need to retransmit messages from the previous session
      so keep a copy of write context in DTLS retransmission buffers instead
      of replacing it after sending CCS. CVE-2013-6450.

      Experimental workaround TLS filler (WTF) extension. · 0467ea68
      Dr. Stephen Henson authored
      Based on a suggested workaround for the "TLS hang bug" (see FAQ and PR#2771):
      if the TLS Client Hello record length value would otherwise be > 255 and less
      that 512 pad with a dummy extension containing zeroes so it is at least 512.
      
      To enable it use an unused extension number (for example 0x4242) using
      e.g. -DTLSEXT_TYPE_wtf=0x4242
      
      WARNING: EXPERIMENTAL, SUBJECT TO CHANGE.

      Add callbacks supporting generation and retrieval of supplemental data... · 36086186
      Scott Deboy authored
      Add callbacks supporting generation and retrieval of supplemental data entries, facilitating RFC 5878 (TLS auth extensions)
      Removed prior audit proof logic - audit proof support was implemented using the generic TLS extension API
      Tests exercising the new supplemental data registration and callback api can be found in ssltest.c.
      Implemented changes to s_server and s_client to exercise supplemental data callbacks via the -auth argument, as well as additional flags to exercise supplemental data being sent only during renegotiation.
