From: Matt Caswell Date: Thu, 10 Sep 2015 08:11:41 +0000 (+0100) Subject: Redefine old state values X-Git-Tag: OpenSSL_1_1_0-pre1~367 X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=c64359db8af1bf759f4496a01c93bac658decc7e;p=openssl Redefine old state values ssl.h and ssl3.h have a number of defines for the various states in the old state machine code. Since this is public API it is not desirable to just remove them. Instead redefine them to the closest equivalent state in the new state machine code. If an application calls SSL_state then the return value can still be compared against these old values if necessary. However not all values have an equivalent state in the new code, so these are just redefined to a dummy value.
