2014-07-31ssl: generalize how the ssl backend identifier is setDaniel Stenberg
Each backend now defines CURL_SSL_BACKEND accordingly. Added the *AXTLS one which was missing previously.
2014-07-31axtls: define curlssl_random using axTLS's PRNGDan Fandrich
2014-07-31cyassl: fix the test for ASN_NO_SIGNER_EDan Fandrich
It's an enum so a macro test won't work. The CyaSSL changelog doesn't say exactly when this error code was introduced, but it's likely to be 2.7.0.
2014-07-31cyassl: use RNG_GenerateBlock to generate a good random numberDan Fandrich
2014-07-30smtp: fixed a segfault during test 1320 torture testDan Fandrich
Under these circumstances, the connection hasn't been fully established and smtp_connect hasn't been called, yet smtp_done still calls the state machine which dereferences the NULL conn pointer in struct pingpong.
2014-07-30vtls: repair build without TLS supportDaniel Stenberg
... by defining Curl_ssl_random() properly
2014-07-30polarssl: provide a (weak) random functionDaniel Stenberg
This now provides a weak random function since PolarSSL doesn't have a quick and easy way to provide a good one. It does however provide the framework to make one so it _can_ and _should_ be done...
2014-07-30cyassl: use the default (weeker) randomDaniel Stenberg
I couldn't find any dedicated function in its API to get a "good" random with.
2014-07-30cyassl: made it compile with version 2.0.6 againDaniel Stenberg
ASN_NO_SIGNER_E didn't exist back then!
2014-07-30vtls: make the random function mandatory in the TLS backendDaniel Stenberg
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.
2014-07-28nss: do not check the version of NSS at run timeKamil Dudka
The minimal required version of NSS is 3.14.x so it does not make sense to check for NSS 3.12.0+ at run time.
2014-07-25c-ares: fix build without IPv6 supportDaniel Stenberg
Bug: http://curl.haxx.se/mail/lib-2014-07/0337.html Reported-by: Spork Schivago
2014-07-25Curl_base64url_encode: unit-tested in 1302Daniel Stenberg
2014-07-25base64: added Curl_base64url_encode()Daniel Stenberg
This is now used by the http2 code. It has two different symbols at the end of the base64 table to make the output "url safe". Bug: https://github.com/tatsuhiro-t/nghttp2/issues/62
2014-07-24SSPI Negotiate: Fix 3 memory leaksMarcel Raad
Curl_base64_decode allocates the output string by itself and two other strings were not freed either.
2014-07-23GSSAPI: remove useless *_MECHANISM defines.Patrick Monnerat
2014-07-23findprotocol: show unsupported protocol within quotesDaniel Stenberg
... to aid when for example prefixed with a space or other weird character.
2014-07-23GSSAPI: private export mechanisms OIDs. OS400: Make RPG binding up to date.Patrick Monnerat
2014-07-23conncache: fix compiler warningMarcel Raad
warning C4267: '=' : conversion from 'size_t' to 'long', possible loss of data The member connection_id of struct connectdata is a long (always a 32-bit signed integer on Visual C++) and the member next_connection_id of struct conncache is a size_t, so one of them should be changed to match the other. This patch the size_t in struct conncache to long (the less invasive change as that variable is only ever used in a single code line). Bug: http://curl.haxx.se/bug/view.cgi?id=1399
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.
2014-07-23http_negotiate: remove unused variableDaniel Stenberg
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.

2014-07-22url.c: use the preferred symbol name: *READDATAMarcel Raad
with CURL_NO_OLDIES defined, it doesn't compile because this deprecated symbol (*INFILE) is used Bug: http://curl.haxx.se/bug/view.cgi?id=1398

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: Avoid invoking ntlm_auth helper with empty usernameDavid Woodhouse
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...
2014-07-14build: set _POSIX_PTHREAD_SEMANTICS on Solaris to get proper getpwuid_rDan Fandrich
2014-07-13gnutls: improved error message if setting cipher list failsDan Fandrich
Reported-by: David Woodhouse
2014-07-13netrc: fixed thread safety problem by using getpwuid_r if availableDan Fandrich
The old way using getpwuid could cause problems in programs that enable reading from netrc files simultaneously in multiple threads. Reported-by: David Woodhouse
2014-07-12netrc: treat failure to find home dir same as missing netrc fileDan Fandrich
This previously caused a fatal error (with a confusing error code, at that). Reported by: Glen A Johnson Jr.
2014-07-12ntlm_wb: Fixed buffer size not being large enough for NTLMv2 sessionsSteve Holme

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.
