OpenSSL passes out and outlen variable uninitialized to
select_next_proto_cb callback function. If the callback function
returns SSL_TLSEXT_ERR_OK, the caller assumes the callback filled
values in out and outlen and processes as such. Previously, if there
is no overlap in protocol lists, curl code does not fill any values in
these variables and returns SSL_TLSEXT_ERR_OK, which means we are
triggering undefined behavior. valgrind warns this.
This patch fixes this issue by fallback to HTTP/1.1 if there is no
overlap.
The variable wasn't assigned at all until step3 which would lead to a
failed connect never assigning the variable and thus returning a bad
value.

Bug: http://curl.haxx.se/mail/lib-2014-04/0203.html
As there's a default connection timeout and this wrongly used the
connection timeout during a transfer after the connection is completed,
this function would trigger timeouts during transfers erroneously.

The debug messages printed inside PolarSSL always seems to end with a
newline. So 'infof()' should not add one. Besides the trace 'line'
should be 'const'.
API has changed since version 1.3. A compatibility header has been created
to ensure forward compatibility for code using old API:
* x509 certificate structure has been renamed to from x509_cert to
x509_crt
* new dedicated setter for RSA certificates ssl_set_own_cert_rsa,
ssl_set_own_cert is for generic keys
* ssl_default_ciphersuites has been replaced by function
ssl_list_ciphersuites()
This patch drops the use of the compatibly header.
Rename x509_cert to x509_crt and add "compat-1.2.h"
include.
This would still need some more thorough conversion
in order to drop "compat-1.2.h" include.
Original commit message was:
Don't omit CN verification in SChannel when an IP address is used.
Side-effect of this change:
SChannel and CryptoAPI do not support the iPAddress subjectAltName
according to RFC 2818. If present, SChannel will first compare the
IP address to the dNSName subjectAltNames and then fallback to the
most specific Common Name in the Subject field of the certificate.
This means that after this change curl will not connect to SSL/TLS
hosts as long as the IP address is not specified in the SAN or CN
of the server certificate or the verifyhost option is disabled.
Perform more work in between sleeps. This is work around the
fact that axtls does not expose any knowledge about when work needs
to be performed. Depending on connection and how often perform is
being called this can save ~25% of time on SSL handshakes (measured
on 20ms latency connection calling perform roughly every 10ms).
when using --http2 one can now selectively disable NPN or ALPN with
--no-alpn and --no-npn. for now honored with NSS only.
TODO: honor this option with GnuTLS and OpenSSL
SSL_ENABLE_ALPN can be used for preprocessor ALPN feature detection,
but not SSL_NEXT_PROTO_SELECTED, since it is an enum value and not a
preprocessor macro.
