* multi: handle errors returned from socket/timer callbacksDaniel Stenberg2021-12-061-2/+3
| | | | | | | | | | | | The callbacks were partially documented to support this. Now the behavior is documented and returning error from either of these callbacks will effectively kill all currently ongoing transfers. Added test 530 to verify Reported-by: Marcelo Juchem Fixes #8083 Closes #8089
* urlapi: provide more detailed return codesbagder/urlapi-returncodesDaniel Stenberg2021-11-251-0/+12
| | | | | | | | | | | | | | | | | | | | Previously, the return code CURLUE_MALFORMED_INPUT was used for almost 30 different URL format violations. This made it hard for users to understand why a particular URL was not acceptable. Since the API cannot point out a specific position within the URL for the problem, this now instead introduces a number of additional and more fine-grained error codes to allow the API to return more exactly in what "part" or section of the URL a problem was detected. Also bug-fixes curl_url_get() with CURLUPART_ZONEID, which previously returned CURLUE_OK even if no zoneid existed. Test cases in 1560 have been adjusted and extended. Tests 1538 and 1559 have been updated. Updated libcurl-errors.3 and curl_url_strerror() accordingly. Closes #8049

* mime: use percent-escaping for multipart form field and file namesPatrick Monnerat2021-11-151-0/+6
| | | | | | | | | | | | | | | | | | Until now, form field and file names where escaped using the backslash-escaping algorithm defined for multipart mails. This commit replaces this with the percent-escaping method for URLs. As this may introduce incompatibilities with server-side applications, a new libcurl option CURLOPT_MIME_OPTIONS with bitmask CURLMIMEOPT_FORMESCAPE is introduced to revert to legacy use of backslash-escaping. This is controlled by new cli tool option --form-escape. New tests and documentation are provided for this feature. Reported by: Ryan Sleevi Fixes #7789 Closes #7805

* curl_url_set: reject spaces in URLs w/o CURLU_ALLOW_SPACEDaniel Stenberg2021-06-151-0/+1
| | | | | | | | | | | | | They were never officially allowed and slipped in only due to sloppy parsing. Spaces (ascii 32) should be correctly encoded (to %20) before being part of a URL. The new flag bit CURLU_ALLOW_SPACE when a full URL is set, makes libcurl allow spaces. Updated test 1560 to verify. Closes #7073

| | | | | | | | | For options that pass in lists or strings that are subsequently parsed and must be correct. This broadens the scope for the option previously known as CURLE_TELNET_OPTION_SYNTAX but the old name is of course still provided as a #define for existing applications. Closes #7175

* CURLOPT_IPRESOLVE: preventing wrong IP version from being usedLucas Clemente Vella2021-05-201-5/+5
| | | | | | | | | | | | | | | | | | | In some situations, it was possible that a transfer was setup to use an specific IP version, but due do DNS caching or connection reuse, it ended up using a different IP version from requested. This commit changes the effect of CURLOPT_IPRESOLVE from simply restricting address resolution to preventing the wrong connection type being used, when choosing a connection from the pool, and to restricting what addresses could be used when establishing a new connection. It is important that all addresses versions are resolved, even if not used in that transfer in particular, because the result is cached, and could be useful for a different transfer with a different CURLOPT_IPRESOLVE setting. Closes #6853
* SSL: support in-memory CA certs for some backendsGilles Vollant2021-05-051-0/+8
| | | | | | | | | | | | | | | | | - New options CURLOPT_CAINFO_BLOB and CURLOPT_PROXY_CAINFO_BLOB to specify in-memory PEM certificates for OpenSSL, Schannel (Windows) and Secure Transport (Apple) SSL backends. Prior to this change PEM certificates could only be imported from a file and not from memory.

* CURLcode: add CURLE_SSL_CLIENTCERTejanchivdorj2021-05-031-0/+1
| | | | | | | | | | When a TLS server requests a client certificate during handshake and none can be provided, libcurl now returns this new error code CURLE_SSL_CLIENTCERT Only supported by Secure Transport and OpenSSL for TLS 1.3 so far. Closes #6721

* schannel: Disable auto credentials; add an option to enable itJay Satiro2021-04-221-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | - Disable auto credentials by default. This is a breaking change for clients that are using it, wittingly or not. - New libcurl ssl option value CURLSSLOPT_AUTO_CLIENT_CERT tells libcurl to automatically locate and use a client certificate for authentication, when requested by the server. - New curl tool options --ssl-auto-client-cert and --proxy-ssl-auto-client-cert map to CURLSSLOPT_AUTO_CLIENT_CERT. This option is only supported for Schannel (the native Windows SSL library). Prior to this change Schannel would, with no notification to the client, attempt to locate a client certificate and send it to the server, when requested by the server. Since the server can request any certificate that supports client authentication in the OS certificate store it could be a privacy violation and unexpected.

* doh: add options to disable ssl verificationJay Satiro2021-02-141-0/+9
| | | | | | | | | | | | | | | | | | | | | | - New libcurl options CURLOPT_DOH_SSL_VERIFYHOST, CURLOPT_DOH_SSL_VERIFYPEER and CURLOPT_DOH_SSL_VERIFYSTATUS do the same as their respective counterparts. - New curl tool options --doh-insecure and --doh-cert-status do the same as their respective counterparts. Prior to this change DOH SSL certificate verification settings for verifyhost and verifypeer were supposed to be inherited respectively from CURLOPT_SSL_VERIFYHOST and CURLOPT_SSL_VERIFYPEER, but due to a bug were not. As a result DOH verification remained at the default, ie enabled, and it was not possible to disable. This commit changes behavior so that the DOH verification settings are independent and not inherited.

* vtls: initial implementation of rustls backendJacob Hoffman-Andrews2021-02-091-1/+2
| | | | | | | | | | | | | | | | | This adds a new TLS backend, rustls. It uses the C-to-rustls bindings from https://github.com/abetterinternet/crustls. Rustls is at https://github.com/ctz/rustls/. There is still a fair bit to be done, like sending CloseNotify on connection shutdown, respecting CAPATH, and properly indicating features like "supports TLS 1.3 ciphersuites." But it works well enough to make requests and receive responses. Blog post for context: https://www.abetterinternet.org/post/memory-safe-curl/ Closes #6350

* http: improve AWS HTTP v4 Signature authDmitry Wagin2021-01-301-2/+2
| | | | | | | | | | | | | | | | | | - Add support services without region and service prefixes in the URL endpoint (ex. Min.IO, GCP, Yandex Cloud, Mail.Ru Cloud Solutions, etc) by providing region and service parameters via aws-sigv4 option. - Add [:region[:service]] suffix to aws-sigv4 option; - Fix memory allocation errors. - Refactor memory management. - Use Curl_http_method instead() STRING_CUSTOMREQUEST. - Refactor canonical headers generating. - Remove repeated sha256_to_hex() usage. - Add some docs fixes. - Add some codestyle fixes. - Add overloaded strndup() for debug - curl_dbg_strndup(). - Update tests.
