2017-09-18cookies: reject oversized cookiesDaniel Stenberg
... instead of truncating them. There's no fixed limit for acceptable cookie names in RFC 6265, but the entire cookie is said to be less than 4096 bytes (section 6.1). This is also what browsers seem to implement. We now allow max 5000 bytes cookie header. Max 4095 bytes length per cookie name and value. Name + value together may not exceed 4096 bytes. Added test 1151 to verify Bug: https://curl.haxx.se/mail/lib-2017-09/0062.html Reported-by: Kevin Smith Closes #1894
2017-09-18socks: fix incorrect port number in SOCKS4 error messageJay Satiro
Prior to this change it appears the SOCKS5 port parsing was erroneously used for the SOCKS4 error message, and as a result an incorrect port would be shown in the error message. Bug: https://github.com/curl/curl/issues/1892 Reported-by: Jackarain@users.noreply.github.com
2017-09-16schannel: Support partial send for when data is too largeMarc Aldorasi
Schannel can only encrypt a certain amount of data at once. Instead of failing when too much data is to be sent at once, send as much data as we can and let the caller send the remaining data by calling send again. Bug: https://curl.haxx.se/mail/lib-2014-07/0033.html Closes https://github.com/curl/curl/pull/1890
2017-09-16openssl: add missing includesDavid Benjamin
lib/vtls/openssl.c uses OpenSSL APIs from BUF_MEM and BIO APIs. Include their headers directly rather than relying on other OpenSSL headers including things. Closes https://github.com/curl/curl/pull/1891
2017-09-15conversions: fix several compiler warningsDaniel Stenberg
2017-09-15non-ascii: use iconv() with 'char **' argumentDaniel Stenberg
Bug: https://curl.haxx.se/mail/lib-2017-09/0031.html
2017-09-15escape.c: error: pointer targets differ in signednessDaniel Stenberg
2017-09-15rtsp: Segfault in rtsp.c when using WRITEDATAMax Dymond
If the INTERLEAVEFUNCTION is defined, then use that plus the INTERLEAVEDATA information when writing RTP. Otherwise, use WRITEFUNCTION and WRITEDATA. Fixes #1880 Closes #1884
2017-09-14URL: on connection re-use, still pick the new remote portDaniel Stenberg
... as when a proxy connection is being re-used, it can still get a different remote port. Fixes #1887 Reported-by: Oli Kingshott

2017-09-11checksrc: verify spaces around equals signsDaniel Stenberg
... as the code style mandates.
2017-09-11Curl_checkheaders: make it available for IMAP and SMTP tooDaniel Stenberg
... not only HTTP uses this now. Closes #1875
2017-09-10mbedtls: enable CA path processingJay Satiro
CA path processing was implemented when mbedtls.c was added to libcurl in fe7590f, but it was never enabled. Bug: https://github.com/curl/curl/issues/1877 Reported-by: SBKarr@users.noreply.github.com
2017-09-08rtsp: do not call fwrite() with NULL pointer FILE *Daniel Stenberg
If the default write callback is used and no destination has been set, a NULL pointer would be passed to fwrite()'s 4th argument. OSS-fuzz bug https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=3327 (not publicly open yet) Detected by OSS-fuzz Closes #1874
2017-09-07http-proxy: when not doing CONNECT, that phase is done immediatelyDaniel Stenberg
`conn->connect_state` is NULL when doing a regular non-CONNECT request over the proxy and should therefor be considered complete at once. Fixes #1853 Closes #1862 Reported-by: Lawrence Wagerfield
2017-09-07OpenSSL: fix yet another mistake while encapsulating SSL backend dataJohannes Schindelin
Another mistake in my manual fixups of the largely mechanical search-and-replace ("connssl->" -> "BACKEND->"), just like the previous commit concerning HTTPS proxies (and hence not caught during my earlier testing). Fixes #1855 Closes #1871 Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de>
2017-09-07OpenSSL: fix erroneous SSL backend encapsulationJohannes Schindelin
In d65e6cc4f (vtls: prepare the SSL backends for encapsulated private data, 2017-06-21), this developer prepared for a separation of the private data of the SSL backends from the general connection data. This conversion was partially automated (search-and-replace) and partially manual (e.g. proxy_ssl's backend data). Sadly, there was a crucial error in the manual part, where the wrong handle was used: rather than connecting ssl[sockindex]' BIO to the proxy_ssl[sockindex]', we reconnected proxy_ssl[sockindex]. The reason was an incorrect location to paste "BACKEND->"... d'oh. Reported by Jay Satiro in https://github.com/curl/curl/issues/1855. Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de>
2017-09-07vtls: fix memory corruptionJay Satiro
Ever since 70f1db321 (vtls: encapsulate SSL backend-specific data, 2017-07-28), the code handling HTTPS proxies was broken because the pointer to the SSL backend data was not swapped between conn->ssl[sockindex] and conn->proxy_ssl[sockindex] as intended, but instead set to NULL (causing segmentation faults). [jes: provided the commit message, tested and verified the patch] Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de>
2017-09-07vtls: switch to CURL_SHA256_DIGEST_LENGTH defineDaniel Stenberg
... instead of the prefix-less version since WolfSSL 3.12 now uses an enum with that name that causes build failures for us. Fixes #1865 Closes #1867 Reported-by: Gisle Vanem
2017-09-06SSL: fix unused parameter warningsJay Satiro
2017-09-06mime: drop internal FILE * support.Patrick Monnerat
- The part kind MIMEKIND_FILE and associated code are suppressed. - Seek data origin offset not used anymore: suppressed. - MIMEKIND_NAMEDFILE renamed MIMEKIND_FILE; associated fields/functions renamed accordingly. - Curl_getformdata() processes stdin via a callback.
2017-09-06configure: remove --enable-soname-bump and SONAME_BUMPDaniel Stenberg
Back in 2008, (and commit 3f3d6ebe665f3) we changed the logic in how we determine the native type for `curl_off_t`. To really make sure we didn't break ABI without bumping SONAME, we introduced logic that attempted to detect that it would use a different size and thus not be compatible. We also provided a manual switch that allowed users to tell configure to bump SONAME by force. Today, we know of no one who ever got a SONAME bump auto-detected and we don't know of anyone who's using the manual bump feature. The auto- detection is also no longer working since we introduced defining curl_off_t in system.h (7.55.0). Finally, this bumping logic is not present in the cmake build. Closes #1861
2017-09-06vtls: select ssl backend case-insensitive (follow-up)Gisle Vanem
- Do a case-insensitive comparison of CURL_SSL_BACKEND env as well. - Change Curl_strcasecompare calls to strcasecompare (maps to the former but shorter). Follow-up to c290b8f. Bug: https://github.com/curl/curl/commit/c290b8f#commitcomment-24094313 Co-authored-by: Jay Satiro
2017-09-05openssl: Integrate Peter Wu's SSLKEYLOGFILE implementationJay Satiro
This is an adaptation of 2 of Peter Wu's SSLKEYLOGFILE implementations. The first one, written for old OpenSSL versions: https://git.lekensteyn.nl/peter/wireshark-notes/tree/src/sslkeylog.c The second one, written for BoringSSL and new OpenSSL versions: https://github.com/curl/curl/pull/1346 Note the first one is GPL licensed but the author gave permission to waive that license for libcurl. As of right now this feature is disabled by default, and does not have a configure option to enable it. To enable this feature define ENABLE_SSLKEYLOGFILE when building libcurl and set environment variable SSLKEYLOGFILE to a pathname that will receive the keys. And in Wireshark change your preferences to point to that key file: Edit > Preferences > Protocols > SSL > Master-Secret Co-authored-by: Peter Wu Ref: https://github.com/curl/curl/pull/1030 Ref: https://github.com/curl/curl/pull/1346 Closes https://github.com/curl/curl/pull/1866
2017-09-05mime: fix a trivial warning.Patrick Monnerat
2017-09-05mime: replace 'struct Curl_mimepart' by 'curl_mimepart' in encoder code.Patrick Monnerat
mime_state is now a typedef.
2017-09-05mime: implement encoders.Patrick Monnerat
curl_mime_encoder() is operational and documented. curl tool -F option is extended with ";encoder=". curl tool --libcurl option generates calls to curl_mime_encoder(). New encoder tests 648 & 649. Test 1404 extended with an encoder specification.
2017-09-05mime: unified to use the typedef'd mime structs everywhereDaniel Stenberg
... and slightly edited to follow our code style better.
2017-09-05openssl: use OpenSSL's default ciphers by defaultKamil Dudka
Up2date versions of OpenSSL maintain the default reasonably secure without breaking compatibility, so it is better not to override the default by curl. Suggested at https://bugzilla.redhat.com/1483972 Closes #1846
2017-09-05http-proxy: treat all 2xx as CONNECT successDaniel Stenberg
Added test 1904 to verify. Reported-by: Lawrence Wagerfield Fixes #1859 Closes #1860
2017-09-04mime: use CURL_ZERO_TERMINATED in examplesViktor Szakats
and some minor whitespace fixes
2017-09-04schannel: return CURLE_SSL_CACERT on failed verificationDaniel Stenberg
... not *CACERT_BADFILE as it isn't really because of a bad file. Bug: https://curl.haxx.se/mail/lib-2017-09/0002.html Closes #1858
2017-09-04lib: bump version info (soname). Adapt and reenable test 1135.Patrick Monnerat
2017-09-03mime: use size_t instead of ssize_t in public API interface.Patrick Monnerat
To support telling a string is nul-terminated, symbol CURL_ZERO_TERMINATED has been introduced. Documentation updated accordingly. symbols in versions updated. Added form API symbols deprecation info.
2017-09-03mime: remove support "-" stdin pseudo-file name in curl_mime_filedata().Patrick Monnerat
This feature is badly supported in Windows: as a replacement, a caller has to use curl_mime_data_cb() with fread, fseek and possibly fclose callbacks to process opened files. The cli tool and documentation are updated accordingly. The feature is however kept internally for form API compatibility, with the known caveats it always had. As a side effect, stdin size is not determined by the cli tool even if possible and this results in a chunked transfer encoding. Test 173 is updated accordingly.
2017-09-03mime: fix some implicit curl_off_t --> size_t conversion warnings.Patrick Monnerat
2017-09-02mime: new MIME API.Patrick Monnerat
Available in HTTP, SMTP and IMAP. Deprecates the FORM API. See CURLOPT_MIMEPOST. Lib code and associated documentation.
2017-09-02checksrc: disable SPACEBEFOREPAREN for case statement.Patrick Monnerat
The case keyword may be followed by a constant expression and thus should allow it to start with an open parenthesis.
2017-09-02Curl_base64_encode: always call with a real data handle.Patrick Monnerat
Some calls in different modules were setting the data handle to NULL, causing segmentation faults when using builds that enable character code conversions.
2017-09-02non-ascii: allow conversion functions to be called with a NULL data handle.Patrick Monnerat
2017-09-02http: fix a memory leakage in checkrtspprefix().Patrick Monnerat

2017-08-31darwinssl: handle long strings in TLS certs (follow-up)Jay Satiro
- Fix handling certificate subjects that are already UTF-8 encoded. Follow-up to b3b75d1 from two days ago. Since then a copy would be skipped if the subject was already UTF-8, possibly resulting in a NULL deref later on.
