2014-07-23http2: more and better error checkingDaniel Stenberg
1 - fixes the warnings when built without http2 support 2 - adds CURLE_HTTP2, a new error code for errors detected by nghttp2 basically when they are about http2 specific things.
2014-07-23cyassl.c: return the correct error code on no CA certDan Fandrich
CyaSSL 3.0.0 returns a unique error code if no CA cert is available, so translate that into CURLE_SSL_CACERT_BADFILE when peer verification is requested.

2014-07-23docs: Improve inline GSS-API naming in code documentationMichael Osipov
2014-07-23curl.h/features: Deprecate GSS-Negotiate macros due to bad namingMichael Osipov
- Replace CURLAUTH_GSSNEGOTIATE with CURLAUTH_NEGOTIATE - CURL_VERSION_GSSNEGOTIATE is deprecated which is served by CURL_VERSION_SSPI, CURL_VERSION_GSSAPI and CURUL_VERSION_SPNEGO now. - Remove display of feature 'GSS-Negotiate'
2014-07-23configure/features: Add feature and version info for GSS-API and SPNEGOMichael Osipov
2014-07-23HTTP: Remove checkprefix("GSS-Negotiate")Michael Osipov
That auth mech has never existed neither on MS nor on Unix side. There is only Negotiate over SPNEGO.
2014-07-23curl_gssapi: Add macros for common mechs and pass them appropriatelyMichael Osipov
Macros defined: KRB5_MECHANISM and SPNEGO_MECHANISM called from HTTP, FTP and SOCKS on Unix
2014-07-22CONNECT: Revert Curl_proxyCONNECT back to 7.29.0 designDaniel Stenberg
This reverts commit cb3e6dfa3511 and instead fixes the problem differently. The reverted commit addressed a test failure in test 1021 by simplifying and generalizing the code flow in a way that damaged the performance. Now we modify the flow so that Curl_proxyCONNECT() again does as much as possible in one go, yet still do test 1021 with and without valgrind. It failed due to mistakes in the multi state machine.

2014-07-16Fix negotiate auth to proxies to track correct stateDavid Woodhouse
2014-07-16Don't abort Negotiate auth when the server has a response for usDavid Woodhouse
It's wrong to assume that we can send a single SPNEGO packet which will complete the authentication. It's a *negotiation* — the clue is in the name. So make sure we handle responses from the server. Curl_input_negotiate() will already handle bailing out if it thinks the state is GSS_S_COMPLETE (or SEC_E_OK on Windows) and the server keeps talking to us, so we should avoid endless loops that way.
2014-07-16Don't clear GSSAPI state between each exchange in the negotiationDavid Woodhouse
GSSAPI doesn't work very well if we forget everything ever time. XX: Is Curl_http_done() the right place to do the final cleanup?
2014-07-16Use SPNEGO for HTTP NegotiateDavid Woodhouse
This is the correct way to do SPNEGO. Just ask for it Now I correctly see it trying NTLMSSP authentication when a Kerberos ticket isn't available. Of course, we bail out when the server responds with the challenge packet, since we don't expect that. But I'll fix that bug next...
2014-07-16Remove all traces of FBOpenSSL SPNEGO supportDavid Woodhouse
This is just fundamentally broken. SPNEGO (RFC4178) is a protocol which allows client and server to negotiate the underlying mechanism which will actually be used to authenticate. This is *often* Kerberos, and can also be NTLM and other things. And to complicate matters, there are various different OIDs which can be used to specify the Kerberos mechanism too. A SPNEGO exchange will identify *which* GSSAPI mechanism is being used, and will exchange GSSAPI tokens which are appropriate for that mechanism. But this SPNEGO implementation just strips the incoming SPNEGO packet and extracts the token, if any. And completely discards the information about *which* mechanism is being used. Then we *assume* it was Kerberos, and feed the token into gss_init_sec_context() with the default mechanism (GSS_S_NO_OID for the mech_type argument). Furthermore... broken as this code is, it was never even *used* for input tokens anyway, because higher layers of curl would just bail out if the server actually said anything *back* to us in the negotiation. We assume that we send a single token to the server, and it accepts it. If the server wants to continue the exchange (as is required for NTLM and for SPNEGO to do anything useful), then curl was broken anyway. So the only bit which actually did anything was the bit in Curl_output_negotiate(), which always generates an *initial* SPNEGO token saying "Hey, I support only the Kerberos mechanism and this is its token". You could have done that by manually just prefixing the Kerberos token with the appropriate bytes, if you weren't going to do any proper SPNEGO handling. There's no need for the FBOpenSSL library at all. The sane way to do SPNEGO is just to *ask* the GSSAPI library to do SPNEGO. That's what the 'mech_type' argument to gss_init_sec_context() is for. And then it should all Just Work™. That 'sane way' will be added in a subsequent patch, as will bug fixes for our failure to handle any exchange other than a single outbound token to the server which results in immediate success.

2014-07-16ntlm_wb: Fix hard-coded limit on NTLM auth packet sizeDavid Woodhouse
Bumping it to 1KiB in commit aaaf9e50ec is all very well, but having hit a hard limit once let's just make it cope by reallocating as necessary.
2014-07-15cookie: avoid mutex deadlockYousuke Kimoto
... by removing the extra mutex locks around th call to Curl_flush_cookies() which takes care of the locking itself already. Bug: http://curl.haxx.se/mail/lib-2014-02/0184.html

2014-07-14gnutls: handle IP address in cert name checkDavid Woodhouse
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...

2014-07-13netrc: fixed thread safety problem by using getpwuid_r if availableDan Fandrich

2014-07-12netrc: treat failure to find home dir same as missing netrc fileDan Fandrich

2014-07-12gnutls: fixed a couple of uninitialized variable referencesDan Fandrich
2014-07-12gnutls: fixed compilation against versions < 2.12.0Dan Fandrich
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.
2014-07-12gnutls: explicitly added SRP to the priority stringDan Fandrich
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.
2014-07-11gnutls: ignore invalid certificate dates with VERIFYPEER disabledDan Fandrich
This makes the behaviour consistent with what happens if a date can be extracted from the certificate but is expired.

2014-07-02progress callback: skip last callback update on errorsRay Satiro
When an error has been detected, skip the final forced call to the progress callback by making sure to pass the current return code variable in the Curl_done() call in the CURLM_STATE_DONE state. This avoids the "extra" callback that could occur even if you returned error from the progress callback. Bug: http://curl.haxx.se/mail/lib-2014-06/0062.html Reported by: Jonathan Cardoso Machado

2014-06-11curl_sasl: revert the goto for error bailoutDaniel Stenberg
They were added because of an older code path that used allocations and should not have been left in the code. With this change the logic goes back to how it was.
2014-06-11NTLM: set a fake entropy for debug builds with CURL_ENTROPY setDaniel Stenberg
Curl_rand() will return a dummy and repatable random value for this case. Makes it possible to write test cases that verify output. Also, fake timestamp with CURL_FORCETIME set. Only when built debug enabled of course. Curl_ssl_random() was not used anymore so it has been removed. Curl_rand() is enough. create_digest_md5_message: generate base64 instead of hex string curl_sasl: also fix memory leaks in some OOM situations
