*) MSVC8 compatibility with OpenSSL 1.0.0
*) fix building OpenSSL-1.0.0 on 64-bit Linux:
make installs the libraries in lib64 directory
and build nginx/Windows against OpenSSL-0.9.8n
SSL fixes:
*) decrease SSL handshake error level to info
*) Set SSL session context for "ssl_session_cache none".
This fixes a bug when client certficate is used and nginx closes connection
with the message: "SSL_GET_PREV_SESSION:session id context uninitialized".
*) add OpenSSL_add_all_algorithms(), this fixes the error
"ASN1_item_verify:unknown message digest algorithm" occurred if
client certificate is signed using sha256WithRSAEncryption
SSL fixes:
*) $ssl_session_id
*) allow "make clean" for OpenSSL, the bug was introduced in r2874
*) disable SSLv2 and use only strong ciphers by default
*) decrease SSL handshake error level to info
various SSL fixes and features:
*) $ssl_client_verify
*) "ssl_verify_client ask" was changed to "ssl_verify_client optional"
*) ssl_crl
*) delete OpenSSL pre-0.9.7 compatibility: the sources were not actually
compatible with OpenSSL 0.9.6 since ssl_session_cache introduction
*) fix memory corruption in $ssl_client_cert
*) issue SNI warning instead of failure: this is too common case
*) use ngx_log_error(), since OpenSSL does not set an error on the failure
*) add SNI support in -V output
this fixes OpenSSL "bad write retry" error, when
*) nginx passed a single buf greater than our buffer (say 32K) to OpenSSL,
*) OpenSSL returns SSL_ERROR_WANT_WRITE,
*) after some time nginx has to send a new data,
*) so there are at least two bufs nginx does pass them directly to OpenSSL,
*) but copies the first buf part to buffer, and sends the buffer to OpenSSL.
*) because the data length is lesser than it was in previous SSL_write():
16K < 32K, OpenSSL returns SSL_R_BAD_WRITE_RETRY.
*) test ssl_client_certificate for ssl_verify_client
*) $ssl_client_cert adds TAB before each line except first one
*) $ssl_client_raw_cert contains certificate as is
