2017-12-01SSL: Avoid magic allocation of SSL backend specific dataJohannes Schindelin
Originally, my idea was to allocate the two structures (or more precisely, the connectdata structure and the four SSL backend-specific strucutres required for ssl[0..1] and proxy_ssl[0..1]) in one go, so that they all could be free()d together. However, getting the alignment right is tricky. Too tricky. So let's just bite the bullet and allocate the SSL backend-specific data separately. As a consequence, we now have to be very careful to release the memory allocated for the SSL backend-specific data whenever we release any connectdata.

2017-11-27openssl: fix boringssl build againDaniel Stenberg
commit d3ab7c5a21e broke the boringssl build since it doesn't have RSA_flags(), so we disable that code block for boringssl builds. Reported-by: W. Mark Kubacki Fixes #2117
2017-11-27curl_ntlm_core.c: use the limits.h's SIZE_T_MAX if providedDaniel Stenberg
2017-11-27global_init: ignore CURL_GLOBAL_SSL's absenseDaniel Stenberg
This bit is no longer used. It is not clear what it meant for users to "init the TLS" in a world with different TLS backends and since the introduction of multissl, libcurl didn't properly work if inited without this bit set. Not a single user responded to the call for users of it: https://curl.haxx.se/mail/lib-2017-11/0072.html Reported-by: Evgeny Grin Assisted-by: Jay Satiro Fixes #2089 Fixes #2083 Closes #2107
2017-11-27ntlm: avoid integer overflow for malloc sizeDaniel Stenberg
Reported-by: Alex Nichols Assisted-by: Kamil Dudka and Max Dymond CVE-2017-8816 Bug: https://curl.haxx.se/docs/adv_2017-11e7.html
2017-11-27wildcardmatch: fix heap buffer overflow in setcharsetDaniel Stenberg
The code would previous read beyond the end of the pattern string if the match pattern ends with an open bracket when the default pattern matching function is used. Detected by OSS-Fuzz: https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=4161 CVE-2017-8817 Bug: https://curl.haxx.se/docs/adv_2017-ae72.html
2017-11-27url: fix alignment of ssl_backend_data structJay Satiro
- Align the array of ssl_backend_data on a max 32 byte boundary. 8 is likely to be ok but I went with 32 for posterity should one of the ssl_backend_data structs change to contain a larger sized variable in the future. Prior to this change (since dev 70f1db3, release 7.56) the connectdata structure was undersized by 4 bytes in 32-bit builds with ssl enabled because long long * was mistakenly used for alignment instead of long long, with the intention being an 8 byte boundary. Also long long may not be an available type. The undersized connectdata could lead to oob read/write past the end in what was expected to be the last 4 bytes of the connection's secondary socket https proxy ssl_backend_data struct (the secondary socket in a connection is used by ftp, others?). Closes https://github.com/curl/curl/issues/2093 CVE-2017-8818 Bug: https://curl.haxx.se/docs/adv_2017-af0a.html
2017-11-25ssh: remove check for a NULL pointer (!)Daniel Stenberg
With this check present, scan-build warns that we might dereference this point in other places where it isn't first checked for NULL. Thus, if it *can* be NULL we have a problem on a few places. However, this pointer should not be possible to be NULL here so I remove the check and thus also three different scan-build warnings. Closes #2111
2017-11-24URL: update "file:" URL handlingMatthew Kerwin
* LOTS of comment updates * explicit error for SMB shares (e.g. "file:////share/path/file") * more strict handling of authority (i.e. "//localhost/") * now accepts dodgy old "C:|" drive letters * more precise handling of drive letters in and out of Windows (especially recognising both "file:c:/" and "file:/c:/") Closes #2110
2017-11-24connect: add support for new TCP Fast Open API on LinuxAlessandro Ghedini
The new API added in Linux 4.11 only requires setting a socket option before connecting, without the whole sento() machinery. Notably, this makes it possible to use TFO with SSL connections on Linux as well, without the need to mess around with OpenSSL (or whatever other SSL library) internals. Closes #2056
2017-11-23connect: improve the bind error messageJay Satiro
eg consider a non-existent interface eth8, curl --interface eth8 Before: curl: (45) Could not resolve host: eth8 After: curl: (45) Couldn't bind to 'eth8' Bug: https://github.com/curl/curl/issues/2104 Reported-by: Alfonso Martone
2017-11-22url: reject ASCII control characters and space in host namesDaniel Stenberg
Host names like "127.0.0.1 moo" would otherwise be accepted by some getaddrinfo() implementations. Updated test 1034 and 1035 accordingly. Fixes #2073 Closes #2092

2017-11-17resolve: allow IP address within [] bracketsDaniel Stenberg
... so that IPv6 addresses can be passed like they can for connect-to and how they're used in URLs. Added test 1324 to verify Reported-by: Alex Malinovich Fixes #2087 Closes #2091
2017-11-15macOS: Fix missing connectx function with Xcode version older than 9.0Pavol Markovic
The previous fix https://github.com/curl/curl/pull/1788 worked just for Xcode 9. This commit extends the fix to older Xcode versions effectively by not using connectx function. Fixes https://github.com/curl/curl/issues/1330 Fixes https://github.com/curl/curl/issues/2080 Closes https://github.com/curl/curl/pull/1336 Closes #2082

Follow-up to aadb7c7. Verified by new test 1263. Closes #2072
2017-11-13zlib/brotli: only include header files in modules needing themPatrick Monnerat
There is a conflict on symbol 'free_func' between openssl/crypto.h and zlib.h on AIX. This is an attempt to resolve it. Bug: https://curl.haxx.se/mail/lib-2017-11/0032.html Reported-By: Michael Felt

2017-11-09--interface: add support for Linux VRFLuca Boccassi
The --interface command (CURLOPT_INTERFACE option) already uses SO_BINDTODEVICE on Linux, but it tries to parse it as an interface or IP address first, which fails in case the user passes a VRF. Try to use the socket option immediately and parse it as a fallback instead. Update the documentation to mention this feature, and that it requires the binary to be ran by root or with CAP_NET_RAW capabilities for this to work. Closes #2024
2017-11-09share: add support for sharing the connection cacheDaniel Stenberg
2017-11-09imap: deal with commands case insensitivelyDaniel Stenberg
As documented in RFC 3501 section 9: https://tools.ietf.org/html/rfc3501#section-9 Closes #2061
2017-11-09connect: store IPv6 connection status after valid connectionDaniel Stenberg
... previously it would store it already in the happy eyeballs stage which could lead to the IPv6 bit being set for an IPv4 connection, leading to curl not wanting to do EPSV=>PASV for FTP transfers. Closes #2053
2017-11-09content_encoding: fix inflate_stream for no bytes availableJay Satiro
- Don't call zlib's inflate() when avail_in stream bytes is 0. This is a follow up to the parent commit 19e66e5. Prior to that change libcurl's inflate_stream could call zlib's inflate even when no bytes were available, causing inflate to return Z_BUF_ERROR, and then inflate_stream would treat that as a hard error and return CURLE_BAD_CONTENT_ENCODING. According to the zlib FAQ, Z_BUF_ERROR is not fatal. This bug would happen randomly since packet sizes are arbitrary. A test of 10,000 transfers had 55 fail (ie 0.55%). Ref: https://zlib.net/zlib_faq.html#faq05 Closes https://github.com/curl/curl/pull/2060
2017-11-07content_encoding: do not write 0 length dataPatrick Monnerat
2017-11-06fnmatch: remove dead codeDaniel Stenberg
There was a duplicate check for backslashes in the setcharset() function. Coverity CID 1420611
2017-11-06url: remove unncessary NULL-checkDaniel Stenberg
Since 'conn' won't be NULL in there and we also access the pointer in there without the check. Coverity CID 1420610

2017-11-05Makefile.m32: add brotli supportViktor Szakats
2017-11-05HTTP: implement Brotli content encodingPatrick Monnerat
This uses the brotli external library (https://github.com/google/brotli). Brotli becomes a feature: additional curl_version_info() bit and structure fields are provided for it and CURLVERSION_NOW bumped. Tests 314 and 315 check Brotli content unencoding with correct and erroneous data. Some tests are updated to accomodate with the now configuration dependent parameters of the Accept-Encoding header.
2017-11-05HTTP: support multiple Content-EncodingsPatrick Monnerat
This is implemented as an output streaming stack of unencoders, the last calling the client write procedure. New test 230 checks this feature. Bug: https://github.com/curl/curl/pull/2002 Reported-By: Daniel Bankhead
2017-11-04url: remove arg value check from CURLOPT_SSH_AUTH_TYPESJay Satiro
Since CURLSSH_AUTH_ANY (aka CURLSSH_AUTH_DEFAULT) is ~0 an arg value check on this option is incorrect; we have to accept any value. Prior to this change since f121575 (7.56.1+) CURLOPT_SSH_AUTH_TYPES erroneously rejected CURLSSH_AUTH_ANY with CURLE_BAD_FUNCTION_ARGUMENT. Bug: https://github.com/curl/curl/commit/f121575#commitcomment-25347120
2017-11-04ntlm: avoid malloc(0) for zero length passwordsDaniel Stenberg
It triggers an assert() when built with memdebug since malloc(0) may return NULL *or* a valid pointer. Detected by OSS-Fuzz: https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=4054 Assisted-by: Max Dymond Closes #2054
