Scott Mitchell fbe0e3506e OpenSslEngine support unwrap plaintext greater than 2^14 and avoid ... infinite loop Motivation: If SslHandler sets jdkCompatibilityMode to false and ReferenceCountedOpenSslEngine sets jdkCompatibilityMode to true there is a chance we will get stuck in an infinite loop if the peer sends a TLS packet with length greater than 2^14 (the maximum length allowed in the TLS 1.2 RFC [1]). However there are legacy implementations which actually send larger TLS payloads than 2^14 (e.g. OpenJDK's SSLSessionImpl [2]) and in this case ReferenceCountedOpenSslEngine will return BUFFER_OVERFLOW in an attempt to notify that a larger buffer is to be used, but if the buffer is already at max size this process will repeat indefinitely. [1] https://tools.ietf.org/html/rfc5246#section-6.2.1 [2] http://hg.openjdk.java.net/jdk8u/jdk8u/jdk/file/d5a00b1e8f78/src/share/classes/sun/security/ssl/SSLSessionImpl.java#l793 Modifications: - Support TLS payload sizes greater than 2^14 in ReferenceCountedOpenSslEngine - ReferenceCountedOpenSslEngine should throw an exception if a BUFFER_OVERFLOW is impossible to rectify Result: No more infinite loop in ReferenceCountedOpenSslEngine due to BUFFER_OVERFLOW and large TLS payload lengths.		2017-11-02 11:42:38 -07:00
