Subject: Keep old method in case of an unsupported protocol
|
||
|
|
X-Git-Url: http://git.openssl.org/gitweb/?p=openssl.git;a=commitdiff_plain;h=392fa7a952e97d82eac6958c81ed1e256e6b8ca5

Keep old method in case of an unsupported protocol
|
||
|
|
|
||
|
|
When we're configured with no-ssl3 and we receive an SSL v3 Client Hello, we set
|
||
|
|
the method to NULL. We didn't used to do that, and it breaks things. This is a
|
||
|
|
regression introduced in 62f45cc27d07187b59551e4fad3db4e52ea73f2c. Keep the old
|
||
|
|
method since the code is not able to deal with a NULL method at this time.
|
||
|
|
|
||
|
|
