Fixes Codacy/CppCheck warnings. Closes https://github.com/curl/curl/pull/3872
2019-05-20ssh: move variable declaration to where it's usedMarcel Raad
This way, we need only one call to free. Closes https://github.com/curl/curl/pull/3873
2019-05-20ssh-libssh: remove unused variableMarcel Raad
sock was only used to be assigned to fd_read. Closes https://github.com/curl/curl/pull/3873

2019-05-19version: make ssl_version buffer match for multi_sslDaniel Gustafsson
When running a multi TLS backend build the version string needs more buffer space. Make the internal ssl_buffer stack buffer match the one in Curl_multissl_version() to allow for the longer string. For single TLS backend builds there is no use in extended to buffer. This is a fallout from #3863 which fixes up the multi_ssl string generation to avoid a buffer overflow when the buffer is too small. Closes #3875 Reviewed-by: Daniel Stenberg <daniel@haxx.se>
2019-05-18http_ntlm_wb: Handle auth for only a single requestSteve Holme
Currently when the server responds with 401 on NTLM authenticated connection (re-used) we consider it to have failed. However this is legitimate and may happen when for example IIS is set configured to 'authPersistSingleRequest' or when the request goes thru a proxy (with 'via' header). Implemented by imploying an additional state once a connection is re-used to indicate that if we receive 401 we need to restart authentication. Missed in fe6049f0.

2019-05-18http_ntlm_wb: Return the correct error on receiving an empty auth messageSteve Holme
Missed in fe20826b as it wasn't implemented in http.c in b4d6db83. Closes #3894

2019-05-16cleanup: remove FIXME and TODO commentsDaniel Stenberg
They serve very little purpose and mostly just add noise. Most of them have been around for a very long time. I read them all before removing or rephrasing them. Ref: #3876 Closes #3883
2019-05-16http_ntlm_wb: Move the type-2 message processing into a dedicated functionSteve Holme
This brings the code inline with the other HTTP authentication mechanisms. Closes #3890
2019-05-15parse_proxy: use the URL parser APIDaniel Stenberg
As we treat a given proxy as a URL we should use the unified URL parser to extract the parts out of it. Closes #3878
2019-05-15http_negotiate: Move the Negotiate state out of the negotiatedata structureSteve Holme
Given that this member variable is not used by the SASL based protocols there is no need to have it here. Closes #3882
2019-05-15http_ntlm: Move the NTLM state out of the ntlmdata structureSteve Holme
Given that this member variable is not used by the SASL based protocols there is no need to have it here.
2019-05-15url: Move the negotiate state type into a dedicated enumSteve Holme
2019-05-14url: Remove duplicate clean up of the winbind variables in conn_shutdown()Steve Holme
Given that Curl_disconnect() calls Curl_http_auth_cleanup_ntlm() prior to calling conn_shutdown() and it in turn performs this, there is no need to perform the same action in conn_shutdown(). Closes #3881
2019-05-14urlapi: require a non-zero host name length when parsing URLDaniel Stenberg
Updated test 1560 to verify. Closes #3880
2019-05-14imap: Fix typo in commentDaniel Gustafsson
2019-05-14url: Remove unnecessary initialisation from allocate_conn()Steve Holme
No need to set variables to zero as calloc() does this for us. Closes #3879
2019-05-13vtls: fix potential ssl_buffer stack overflowDaniel Gustafsson
In Curl_multissl_version() it was possible to overflow the passed in buffer if the generated version string exceeded the size of the buffer. Fix by inverting the logic, and also make sure to not exceed the local buffer during the string generation.

2019-05-12easy: fix another "clarify calculation precedence" warningMarcel Raad
I missed this one in commit 6b3dde7fe62ea5a557fd1fd323fac2bcd0c2e9be.
2019-05-12build: fix "clarify calculation precedence" warningsMarcel Raad
Codacy/CppCheck warns about this. Consistently use parentheses as we already do in some places to silence the warning. Closes https://github.com/curl/curl/pull/3866

2019-05-11doh: disable DOH for the cases it doesn't workDaniel Stenberg
Due to limitations in Curl_resolver_wait_resolv(), it doesn't work for DOH resolves. This fix disables DOH for those. Limitation added to KNOWN_BUGS. Fixes #3850 Closes #3857

2019-05-10Revert "multi: support verbose conncache closure handle"Jay Satiro
This reverts commit b0972bc. - No longer show verbose output for the conncache closure handle. The offending commit was added so that the conncache closure handle would inherit verbose mode from the user's easy handle. (Note there is no way for the user to set options for the closure handle which is why that was necessary.) Other debug settings such as the debug function were not also inherited since we determined that could lead to crashes if the user's per-handle private data was used on an unexpected handle. The reporter here says he has a debug function to capture the verbose output, and does not expect or want any output to stderr; however because the conncache closure handle does not inherit the debug function the verbose output for that handle does go to stderr. There are other plausible scenarios as well such as the user redirects stderr on their handle, which is also not inherited since it could lead to crashes when used on an unexpected handle. Short of allowing the user to set options for the conncache closure handle I don't think there's much we can safely do except no longer inherit the verbose setting.

2019-05-08http: Ignore HTTP/2 prior knowledge setting for HTTP proxiesJay Satiro
- Do not switch to HTTP/2 for an HTTP proxy that is not tunnelling to the destination host. We already do something similar for HTTPS proxies by not sending h2. [1] Prior to this change setting CURL_HTTP_VERSION_2_PRIOR_KNOWLEDGE would incorrectly use HTTP/2 to talk to the proxy, which is not something we support (yet?). Also it's debatable whether or not that setting should apply to HTTP/2 proxies.

2019-05-08OpenSSL: Report -fips in version if OpenSSL is built with FIPSRicky Leverence
Older versions of OpenSSL report FIPS availabilty via an OPENSSL_FIPS define. It uses this define to determine whether to publish -fips at the end of the version displayed. Applications that utilize the version reported by OpenSSL will see a mismatch if they compare it to what curl reports, as curl is not modifying the version in the same way. This change simply adds a check to see if OPENSSL_FIPS is defined, and will alter the reported version to match what OpenSSL itself provides. This only appears to be applicable in versions of OpenSSL <1.1.1 Closes #3771
2019-05-07nss: allow fifos and character devices for certificates.Frank Gevaerts
Currently you can do things like --cert <(cat ./cert.crt) with (at least) the openssl backend, but that doesn't work for nss because is_file rejects fifos. I don't actually know if this is sufficient, nss might do things internally (like seeking back) that make this not work, so actual testing is needed. Closes #3807
