They tend to never get updated anyway so they're frequently inaccurate
and we never go back to revisit them anyway. We document issues to work
on properly in KNOWN_BUGS and TODO instead.

If GnuTLS fails to read the certificate then include whatever reason it
provides in the failure message reported to the client.

The gnutls vtls back-end was previously ignoring any password set via
CURLOPT_KEYPASSWD. Presumably this was because
gnutls_certificate_set_x509_key_file did not support encrypted keys.
gnutls now has a gnutls_certificate_set_x509_key_file2 function that
does support encrypted keys. Let's determine at compile time whether the
available gnutls supports this new function. If it does then use it to
pass the password. If it does not then emit a helpful diagnostic if a
password is set. This is preferable to the previous behaviour of just
failing to read the certificate without giving a reason in that case.

Add a "pinnedpubkey" section to the "Server Certificate" verbose
Bug: https://github.com/bagder/curl/issues/410
Reported-by: W. Mark Kubacki
Closes #430

- Change fopen calls to use FOPEN_READTEXT instead of "r" or "rt"
- Change fopen calls to use FOPEN_WRITETEXT instead of "w" or "wt"
This change is to explicitly specify when we need to read/write text.
Unfortunately 't' is not part of POSIX fopen so we can't specify it
directly. Instead we now have FOPEN_READTEXT, FOPEN_WRITETEXT.
Prior to this change we had an issue on Windows if an application that
uses libcurl overrides the default file mode to binary. The default file
mode in Windows is normally text mode (translation mode) and that's what
libcurl expects.

Stop curl from failing when non-fatal alert is received during
handshake. This e.g. fixes lots of problems when working with https
sites through proxies.
|
|
Also print the revocation reason if appropriate.

Coverity CID 1291167 pointed out that 'rc' was received but never used when
gnutls_credentials_set() was used. Added return code check now.
|
|
Coverity CID 1291165 pointed out 'chainp' could be dereferenced when
NULL if gnutls_certificate_get_peers() had previously failed.
|
|
Coverity CID 1291166 pointed out that we could read this variable
uninitialized.

Instead of priting cipher and MAC algorithms names separately, print the
whole cipher suite string which also includes the key exchange algorithm,
along with the negotiated TLS version.

Carrying on from commit 037cd0d991, removed the following unimplemented
instances of curlssl_close_all():
Curl_axtls_close_all()
Curl_darwinssl_close_all()
Curl_cyassl_close_all()
Curl_gskit_close_all()
Curl_gtls_close_all()
Curl_nss_close_all()
Curl_polarssl_close_all()

Also known as "status_request" or OCSP stapling, defined in RFC6066 section 8.
This requires GnuTLS 3.1.3 or higher to build, however it's recommended to use
at least GnuTLS 3.3.11 since previous versions had a bug that caused the OCSP
response verfication to fail even on valid responses.

The return type of this function is a boolean value, and even uses a
bool internally, so use bool in the function declaration as well as
the variables that store the return value, to avoid any confusion.

To force each backend implementation to really attempt to provide proper
random. If a proper random function is missing, then we can explicitly
make use of the default one we use when TLS support is missing.
This commit makes sure it works for darwinssl, gnutls, nss and openssl.

Before GnuTLS 3.3.6, the gnutls_x509_crt_check_hostname() function
didn't actually check IP addresses in SubjectAltName, even though it was
explicitly documented as doing so. So do it ourselves...

The AES-GCM ciphers were added to GnuTLS as late as ver. 3.0.1 but
the code path in which they're referenced here is only ever used for
somewhat older GnuTLS versions. This caused undeclared identifier errors
when compiling against those.
|
|
This seems to have become necessary for SRP support to work starting
with GnuTLS ver. 2.99.0. Since support for SRP was added to GnuTLS
before the function that takes this priority string, there should be no
issue with backward compatibility.
|
|
This makes the behaviour consistent with what happens if a date can
be extracted from the certificate but is expired.
|
|
It might not be the most useful combo, but...

gnutls_x509_crt_import() must not be called with a NULL certificate

We're progressing throught drafts so there's no point in having a fixed
one in a symbol that'll survive.

Disable ALPN if requested by the user.
|
|
Add ALPN support when using GnuTLS >= 3.2.0. This allows
libcurl to negotiate HTTP/2.0 for https connections when
built with GnuTLS.
See:
http://www.gnutls.org/manual/gnutls.html#Application-Layer-Protocol-Negotiation-_0028ALPN_0029
http://tools.ietf.org/html/draft-ietf-tls-applayerprotoneg-04
|
|
Make GnuTLS old and new consistent, specify the desired protocol, cipher
and certificate type in always in both modes. Disable insecure ciphers
as reported by howsmyssl.com. Honor not only --sslv3, but also the
--tlsv1[.N] switches.
