2018-05-31option: disallow username in URLBjörn Stenberg
Adds CURLOPT_DISALLOW_USERNAME_IN_URL and --disallow-username-in-url. Makes libcurl reject URLs with a username in them. Closes #2340
2018-05-24multi: provide a socket to wait for in Curl_protocol_getsockDaniel Stenberg
... even when there's no protocol specific handler setup. Bug: https://curl.haxx.se/mail/lib-2018-05/0062.html Reported-by: Sean Miller Closes #2600
2018-05-14lib: Fix format specifiersRikard Falkeborn
2018-05-04vtls: use unified "supports" bitfield member in backendsDaniel Stenberg
... instead of previous separate struct fields, to make it easier to extend and change individual backends without having to modify them all. closes #2547
2018-04-19detect_proxy: only show proxy use if it had contentsDaniel Stenberg
2018-04-18schannel: add support for CURLOPT_CAINFODan McNulty
- Move verify_certificate functionality in schannel.c into a new file called schannel_verify.c. Additionally, some structure defintions from schannel.c have been moved to schannel.h to allow them to be used in schannel_verify.c. - Make verify_certificate functionality for Schannel available on all versions of Windows instead of just Windows CE. verify_certificate will be invoked on Windows CE or when the user specifies CURLOPT_CAINFO and CURLOPT_SSL_VERIFYPEER. - In verify_certificate, create a custom certificate chain engine that exclusively trusts the certificate store backed by the CURLOPT_CAINFO file. - doc updates of --cacert/CAINFO support for schannel - Use CERT_NAME_SEARCH_ALL_NAMES_FLAG when invoking CertGetNameString when available. This implements a TODO in schannel.c to improve handling of multiple SANs in a certificate. In particular, all SANs will now be searched instead of just the first name. - Update tool_operate.c to not search for the curl-ca-bundle.crt file when using Schannel to maintain backward compatibility. Previously, any curl-ca-bundle.crt file found in that search would have been ignored by Schannel. But, with CAINFO support, the file found by that search would have been used as the certificate store and could cause issues for any users that have curl-ca-bundle.crt in the search path. - Update url.c to not set the build time CURL_CA_BUNDLE if the selected SSL backend is Schannel. We allow setting CA location for schannel only when explicitly specified by the user via CURLOPT_CAINFO / --cacert. - Add new test cases 3000 and 3001. These test cases check that the first and last SAN, respectively, matches the connection hostname. New test certificates have been added for these cases. For 3000, the certificate prefix is Server-localhost-firstSAN and for 3001, the certificate prefix is Server-localhost-secondSAN. - Remove TODO 15.2 (Add support for custom server certificate validation), this commit addresses it. Closes https://github.com/curl/curl/pull/1325
2018-04-11proxy: show getenv proxy use in verbose outputDaniel Stenberg
... to aid debugging etc as it sometimes isn't immediately obvious why curl uses or doesn't use a proxy. Inspired by #2477 Closes #2480
2018-04-06file: restore old behavior for file:////foo/bar URLsJon DeVree
curl 7.57.0 and up interpret this according to Appendix E.3.2 of RFC 8089 but then returns an error saying this is unimplemented. This is actually a regression in behavior on both Windows and Unix. Before curl 7.57.0 this URL was treated as a path of "//foo/bar" and then passed to the relevant OS API. This means that the behavior of this case is actually OS dependent. The Unix path resolution rules say that the OS must handle swallowing the extra "/" and so this path is the same as "/foo/bar" The Windows path resolution rules say that this is a UNC path and automatically handles the SMB access for the program. So curl on Windows was already doing Appendix E.3.2 without any special code in curl. Regression Closes #2438
2018-03-04NO_PROXY: fix for IPv6 numericals in the URLDaniel Stenberg
Added test 1265 that verifies. Reported-by: steelman on github Fixes #2353 Closes #2355
2018-02-23spelling fixesViktor Szakats
Detected using the `codespell` tool. Also contains one URL protocol upgrade. Closes https://github.com/curl/curl/pull/2334
2018-02-20url: Add option CURLOPT_HAPPY_EYEBALLS_TIMEOUTAnders Bakken
- Add new option CURLOPT_HAPPY_EYEBALLS_TIMEOUT to set libcurl's happy eyeball timeout value. - Add new optval macro CURL_HET_DEFAULT to represent the default happy eyeballs timeout value (currently 200 ms). - Add new tool option --happy-eyeballs-timeout-ms to expose CURLOPT_HAPPY_EYEBALLS_TIMEOUT. The -ms suffix is used because the other -timeout options in the tool expect seconds not milliseconds. Closes https://github.com/curl/curl/pull/2260
2018-01-23CONNECT_TO: fail attempt to set an IPv6 numerical without IPv6 supportDaniel Stenberg
Bug: https://curl.haxx.se/mail/lib-2018-01/0087.html Reported-by: John Hascall Closes #2257
2018-01-05build: remove HAVE_LIMITS_H checkJay Satiro
.. because limits.h presence isn't optional, it's required by C89. Ref: http://port70.net/~nsz/c/c89/c89-draft.html#2.2.4.2 Closes https://github.com/curl/curl/pull/2215
2017-12-20curl_easy_reset: release mime-related data.Patrick Monnerat
Move curl_mime_initpart() and curl_mime_cleanpart() calls to lower-level functions dealing with UserDefined structure contents. This avoids memory leakages on curl-generated part mime headers. New test 2073 checks this using the cli tool --next option: it triggers a valgrind error if bug is present. Bug: https://curl.haxx.se/mail/lib-2017-12/0060.html Reported-by: Martin Galvan
2017-12-08curl: remove __EMX__ #ifdefsDaniel Stenberg
These are OS/2-specific things added to the code in the year 2000. They were always ugly. If there's any user left, they still don't need it done this way. Closes #2166
2017-12-06URL: tolerate backslash after drive letter for FILE:Jan-E
... as in "file://c:\some\path\curl.out" Reviewed-by: Matthew Kerwin Closes #2154
2017-12-05conncache: only allow multiplexing within same multi handleDaniel Stenberg
Connections that are used for HTTP/1.1 Pipelining or HTTP/2 multiplexing only get additional transfers added to them if the existing connection is held by the same multi or easy handle. libcurl does not support doing HTTP/2 streams in different threads using a shared connection. Closes #2152
2017-12-05conncache: fix several lock issuesDaniel Stenberg
If the lock is released before the dealings with the bundle is over, it may have changed by another thread in the mean time. Fixes #2132 Fixes #2151 Closes #2139
2017-12-01libssh: added SFTP supportNikos Mavrogiannopoulos
The SFTP back-end supports asynchronous reading only, limited to 32-bit file length. Writing is synchronous with no other limitations. This also brings keyboard-interactive authentication. Signed-off-by: Nikos Mavrogiannopoulos <nmav@gnutls.org>
2017-12-01Added support for libssh SSH SCP back-endNikos Mavrogiannopoulos
libssh is an alternative library to libssh2. https://www.libssh.org/ That patch set also introduces support for ECDSA ed25519 keys, as well as gssapi authentication. Signed-off-by: Nikos Mavrogiannopoulos <nmav@redhat.com>
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. Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de> Closes #2119
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
2017-11-24URL: 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
2017-11-22url: 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

2017-11-06url: 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
2017-11-05HTTP: 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
2017-11-03CURLOPT_INFILESIZE: accept -1Daniel Stenberg

2017-10-28Curl_timeleft: change return type to timediff_tDaniel Stenberg
returning 'time_t' is problematic when that type is unsigned and we return values less than zero to signal "already expired", used in several places in the code. Closes #2021

2017-10-25time: rename Curl_tvnow to Curl_nowDaniel Stenberg
... since the 'tv' stood for timeval and this function does not return a timeval struct anymore. Also, cleaned up the Curl_timediff*() functions to avoid typecasts and clean up the descriptive comments. Closes #2011
2017-10-25timediff: return timediff_t from the time diff functionsDaniel Stenberg
... to cater for systems with unsigned time_t variables. - Renamed the functions to curlx_timediff and Curl_timediff_us. - Added overflow protection for both of them in either direction for both 32 bit and 64 bit time_ts - Reprefixed the curlx_time functions to use Curl_* Reported-by: Peter Piekarski Fixes #2004 Closes #2005
2017-10-16setopt: range check most long optionsDaniel Stenberg
... filter early instead of risking "funny values" having to be dealt with elsewhere.
2017-10-16setopt: avoid integer overflows when setting millsecond valuesDaniel Stenberg
... that are multiplied by 1000 when stored. For 32 bit long systems, the max value accepted (2147483 seconds) is > 596 hours which is unlikely to ever be set by a legitimate application - and previously it didn't work either, it just caused undefined behavior. Also updated the man pages for these timeout options to mention the return code. Closes #1938
2017-10-11url: Update current connection SSL verify params in setoptArtak Galoyan
Now VERIFYHOST, VERIFYPEER and VERIFYSTATUS options change during active connection updates the current connection's (i.e.'connectdata' structure) appropriate ssl_config (and ssl_proxy_config) structures variables, making these options effective for ongoing connection. This functionality was available before and was broken by the following change: "proxy: Support HTTPS proxy and SOCKS+HTTP(s)" CommitId: cb4e2be7c6d42ca0780f8e0a747cecf9ba45f151.

2017-09-30Set and use more necessary options when some protocols are disabledDan Fandrich
When curl and libcurl are built with some protocols disabled, they stop setting and receiving some options that don't make sense with those protocols. In particular, when HTTP is disabled many options aren't set that are used only by HTTP. However, some options that appear to be HTTP-only are actually used by other protocols as well (some despite having HTTP in the name) and should be set, but weren't. This change now causes some of these options to be set and used for more (or for all) protocols. In particular, this fixes tests 646 through 649 in an HTTP-disabled build, which use the MIME API in the mail protocols.
2017-09-28reuse_conn: don't copy flags that are known to be equalMichael Kaufmann
A connection can only be reused if the flags "conn_to_host" and "conn_to_port" match. Therefore it is not necessary to copy these flags in reuse_conn(). Closes #1918
2017-09-14URL: on connection re-use, still pick the new remote portDaniel Stenberg
