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

2019-05-03urlapi: strip off scope id from numerical IPv6 addressesDaniel Stenberg

2019-05-01ConnectionExists: improve non-multiplexing use caseDaniel Stenberg
- better log output - make sure multiplex is enabled for it to be used
2019-05-01multi: provide Curl_multiuse_state to update informationDaniel Stenberg
As soon as a TLS backend gets ALPN conformation about the specific HTTP version it can now set the multiplex situation for the "bundle" and trigger moving potentially queued up transfers to the CONNECT state.
2019-05-01process_pending_handles: mark queued transfers as previously pendingDaniel Stenberg
With transfers being queued up, we only move one at a a time back to the CONNECT state but now we mark moved transfers so that when a moved transfer is confirmed "successful" (it connected) it will trigger the move of another pending transfer. Previously, it would otherwise wait until the transfer was done before doing this. This makes queued up pending transfers get processed (much) faster.

2019-05-01cookie: Guard against possible NULL ptr derefDaniel Gustafsson
In case the name pointer isn't set (due to memory pressure most likely) we need to skip the prefix matching and reject with a badcookie to avoid a possible NULL pointer dereference. Closes #3820 #3821 Reported-by: Jonathan Moerman Reviewed-by: Daniel Stenberg <daniel@haxx.se>

2019-04-29CURL_MAX_INPUT_LENGTH: largest acceptable string input sizeDaniel Stenberg
This limits all accepted input strings passed to libcurl to be less than CURL_MAX_INPUT_LENGTH (8000000) bytes, for these API calls: curl_easy_setopt() and curl_url_set(). The 8000000 number is arbitrary picked and is meant to detect mistakes or abuse, not to limit actual practical use cases. By limiting the acceptable string lengths we also reduce the risk of integer overflows all over. NOTE: This does not apply to `CURLOPT_POSTFIELDS`. Test 1559 verifies. Closes #3805

Just like we do for mbed TLS, use our local implementation of MD4 when OpenSSL doesn't support it. This allows a type-3 message to include the NT response.

2019-04-20altsvc: Fix building with cookies disablesPo-Chuan Hsieh
ALTSVC requires Curl_get_line which is defined in lib/cookie.c inside a #if check of HTTP and COOKIES. That makes Curl_get_line undefined if COOKIES is disabled. Fix by splitting out the function into a separate file which can be included where needed.

2019-04-13CURLOPT_ADDRESS_SCOPE: fix range check and moretmilburn
Commit 9081014 fixed most of the confusing issues between scope id and scope however 844896d added bad limits checking assuming that the scope is being set and not the scope id. I have fixed the documentation so it all refers to scope ids. In addition Curl_if2ip refered to the scope id as remote_scope_id which is incorrect, so I renamed it to local_scope_id.

Make functions no-ops if neither both USE_THREADS_POSIX and HAVE_PTHREAD_H nor both USE_THREADS_WIN32 and HAVE_PROCESS_H are defined.
