[tor/master] Remove rectify_client_ciphers as needless.
by nickm＠torproject.org 02 Jun '15

commit 80082b7185feb77f83ff484e1779438aa0396634 Author: Nick Mathewson <nickm(a)torproject.org> Date: Tue May 26 10:56:54 2015 -0400 Remove rectify_client_ciphers as needless. We previously used this function instead of SSL_set_cipher_list() to set up a stack of client SSL_CIPHERs for these reasons: A) In order to force a particular order of the results. B) In order to be able to include dummy entries for ciphers that this build of openssl did not support, so we could impersonate Firefox harder. But we no longer do B, since we merged proposal 198 and stopped lying about what ciphers we know. And A was actually pointless, since I had misread the implementation of SSL_set_cipher_list(). It _does_ do some internal sorting, but that is pre-sorting on the master list of ciphers, not sorting on the user's preferred order. --- src/common/tortls.c | 184 --------------------------------------------------- 1 file changed, 184 deletions(-) diff --git a/src/common/tortls.c b/src/common/tortls.c index 654efb5..01bccd7 100644 --- a/src/common/tortls.c +++ b/src/common/tortls.c @@ -217,16 +217,6 @@ struct tor_tls_t { void *callback_arg; }; -#ifdef V2_HANDSHAKE_CLIENT -/** An array of fake SSL_CIPHER objects that we use in order to trick OpenSSL - * in client mode into advertising the ciphers we want.
