2019-08-09http3: make connection reuse workDaniel Stenberg
Closes #4204
2019-08-01timediff: make it 64 bit (if possible) even with 32 bit time_tDaniel Stenberg
... to make it hold microseconds too. Fixes #4165 Closes #4168
2019-07-21HTTP3: initial (experimental) supportDaniel Stenberg
USe configure --with-ngtcp2 or --with-quiche Using either option will enable a HTTP3 build. Co-authored-by: Alessandro Ghedini <alessandro@ghedini.me> Closes #3500
2019-06-10bindlocal: detect and avoid IP version mismatches in bind()Daniel Stenberg
Reported-by: Alex Grebenschikov Fixes #3993 Closes #4002
2019-05-21udpateconninfo: mark variable unusedDaniel Gustafsson
When compiling without getpeername() or getsockname(), the sockfd paramter to Curl_udpateconninfo() became unused after commit e91e481612 added ifdef guards. Closes #3910 Fixes https://curl.haxx.se/dev/log.cgi?id=20190520172441-32196 Reviewed-by: Marcel Raad, Daniel Stenberg
2019-05-20lib: reduce variable scopesMarcel Raad
Fixes Codacy/CppCheck warnings. Closes https://github.com/curl/curl/pull/3872
2019-05-17libcurl: #ifdef away more code for disabled features/protocolsDaniel Stenberg
2019-05-11doh: disable DOH for the cases it doesn't workDaniel Stenberg
Due to limitations in Curl_resolver_wait_resolv(), it doesn't work for DOH resolves. This fix disables DOH for those. Limitation added to KNOWN_BUGS. Fixes #3850 Closes #3857
2019-04-13singleipconnect: show port in the verbose "Trying ..." messageDaniel Stenberg
To aid debugging better.
2019-02-27urldata: convert bools to bitfields and move to endDaniel Stenberg
This allows the compiler to pack and align the structs better in memory. For a rather feature-complete build on x86_64 Linux, gcc 8.1.2 makes the Curl_easy struct 4.9% smaller. From 6312 bytes to 6000. Removed an unused struct field. No functionality changes. Closes #3610
2019-02-26strerror: make the strerror function use local buffersDaniel Stenberg
Instead of using a fixed 256 byte buffer in the connectdata struct. In my build, this reduces the size of the connectdata struct by 11.8%, from 2160 to 1904 bytes with no functionality or performance loss. This also fixes a bug in schannel's Curl_verify_certificate where it called Curl_sspi_strerror when it should have called Curl_strerror for string from GetLastError. the only effect would have been no text or the wrong text being shown for the error. Co-authored-by: Jay Satiro Closes #3612

urlapi: turn three local-only functions into statics conncache: make conncache_find_first_connection static multi: make detach_connnection static connect: make getaddressinfo static curl_ntlm_core: make hmac_md5 static http2: make two functions static http: make http_setup_conn static connect: make tcpnodelay static tests: make UNITTEST a thing to mark functions with, so they can be static for normal builds and non-static for unit test builds ... and mark Curl_shuffle_addr accordingly. url: make up_free static setopt: make vsetopt static curl_endian: make write32_le static rtsp: make rtsp_connisdead static warnless: remove unused functions memdebug: remove one unused function, made another static
2018-11-29connect: fix building for recent versions of MinixSevan Janiyan
EBADIOCTL doesn't exist on more recent Minix. There have also been substantial changes to the network stack. Fixes build on Minix 3.4rc Closes https://github.com/curl/curl/pull/3323
2018-11-23snprintf: renamed and we now only use msnprintf()Daniel Stenberg
The function does not return the same value as snprintf() normally does, so readers may be mislead into thinking the code works differently than it actually does. A different function name makes this easier to detect. Reported-by: Tomas Hoger Assisted-by: Daniel Gustafsson Fixes #3296 Closes #3297
2018-11-20ares: remove fd from multi fd set when ares is about to close the fdRomain Fliedel
When using c-ares for asyn dns, the dns socket fd was silently closed by c-ares without curl being aware. curl would then 'realize' the fd has been removed at next call of Curl_resolver_getsock, and only then notify the CURLMOPT_SOCKETFUNCTION to remove fd from its poll set with CURL_POLL_REMOVE. At this point the fd is already closed. By using ares socket state callback (ARES_OPT_SOCK_STATE_CB), this patch allows curl to be notified that the fd is not longer needed for neither for write nor read. At this point by calling Curl_multi_closed we are able to notify multi with CURL_POLL_REMOVE before the fd is actually closed by ares. In asyn-ares.c Curl_resolver_duphandle we can't use ares_dup anymore since it does not allow passing a different sock_state_cb_data Closes #3238
2018-06-21url: fix dangling conn->data pointerDaniel Stenberg
By masking sure to use the *current* easy handle with extracted connections from the cache, and make sure to NULLify the ->data pointer when the connection is put into the cache to make this mistake easier to detect in the future. Reported-by: Will Dietz Fixes #2669 Closes #2672
2018-06-11cppcheck: fix warningsMarian Klymov
- Get rid of variable that was generating false positive warning (unitialized) - Fix issues in tests - Reduce scope of several variables all over etc Closes #2631
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
2018-02-20CURLOPT_RESOLVE: Add support for multiple IP addresses per entryAnders Bakken
This enables users to preresolve but still take advantage of happy eyeballs and trying multiple addresses if some are not connecting. Ref: https://github.com/curl/curl/pull/2260
2018-02-15TODO fixed: Detect when called from within callbacksBjörn Stenberg
Closes #2302
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
2017-11-15macOS: 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
2017-11-12connect.c: remove executable bit on fileOrgad Shaneh
Closes #2071
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
2017-11-09connect: 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
2017-10-29timeleft: made two more users of Curl_timeleft use timediff_tDaniel 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
2017-09-29connect: fix race condition with happy eyeballs timeoutAnders Bakken
The timer should be started after conn->connecttime is set. Otherwise the timer could expire without this condition being true: /* should we try another protocol family? */ if(i == 0 && conn->tempaddr[1] == NULL && curlx_tvdiff(now, conn->connecttime) >= HAPPY_EYEBALLS_TIMEOUT) { Ref: #1928

2017-09-11code style: use spaces around equals signsDaniel Stenberg
2017-08-16configure: check for __builtin_available() availability (#1788)Nick Zitzmann
This change does two things: 1. It un-breaks the build in Xcode 9.0. (Xcode 9.0 is currently failing trying to compile connectx() in lib/connect.c.) 2. It finally weak-links the connectx() function, and falls back on connect() when run on older operating systems.
2017-07-28timeval: struct curltime is a struct timeval replacementDaniel Stenberg
... to make all libcurl internals able to use the same data types for the struct members. The timeval struct differs subtly on several platforms so it makes it cumbersome to use everywhere. Ref: #1652 Closes #1693
2017-07-10curl_setup_once: Remove ERRNO/SET_ERRNO macrosJay Satiro
Prior to this change (SET_)ERRNO mapped to GetLastError/SetLastError for Win32 and regular errno otherwise. I reviewed the code and found no justifiable reason for conflating errno on WIN32 with GetLastError/SetLastError. All Win32 CRTs support errno, and any Win32 multithreaded CRT supports thread-local errno. Fixes https://github.com/curl/curl/issues/895 Closes https://github.com/curl/curl/pull/1589
2017-07-04configure: remove checks for 5 functions never usedDaniel Stenberg
fork, getprotobyname, inet_addr, perror, uname closes #1638
2017-06-08expire: remove Curl_expire_latest()Daniel Stenberg
With the introduction of expire IDs and the fact that existing timers can be removed now and thus never expire, the concept with adding a "latest" timer is not working anymore as it risks to not expire at all. So, to be certain the timers actually are in line and will expire, the plain Curl_expire() needs to be used. The _latest() function was added as a sort of shortcut in the past that's quite simply not necessary anymore. Follow-up to 31b39c40cf90 Reported-by: Paul Harris Closes #1555
2017-05-10multi: assign IDs to all timers and make each timer singletonDaniel Stenberg
A) reduces the timeout lists drastically B) prevents a lot of superfluous loops for timers that expires "in vain" when it has actually already been extended to fire later on
2017-03-30connect: fix unreferenced parameter warningMarcel Raad
When CURL_DISABLE_VERBOSE_STRINGS is defined, the reason parameter in Curl_conncontrol is not used as the infof macro expands to nothing.
2017-03-13Improve code readbilitySylvestre Ledru
... by removing the else branch after a return, break or continue. Closes #1310
2016-12-19http_proxy: Fix proxy CONNECT hang on pending dataJay Satiro
- Check for pending data before waiting on the socket. Bug: https://github.com/curl/curl/issues/1156 Reported-by: Adam Langley
2016-12-18Curl_getconnectinfo: avoid checking if the connection is closedIsaac Boukris
It doesn't benefit us much as the connection could get closed at any time, and also by checking we lose the ability to determine if the socket was closed by reading zero bytes. Reported-by: Michael Kaufmann Closes https://github.com/curl/curl/pull/1134
2016-12-13checksrc: stricter no-space-before-paren enforcementDaniel Stenberg
In order to make the code style more uniform everywhere
2016-11-25add CURLINFO_SCHEME, CURLINFO_PROTOCOL, and %{scheme}Frank Gevaerts
Adds access to the effectively used protocol/scheme to both libcurl and curl, both in string and numeric (CURLPROTO_*) form. Note that the string form will be uppercase, as it is just the internal string. As these strings are declared internally as const, and all other strings returned by curl_easy_getinfo() are de-facto const as well, string handling in getinfo.c got const-ified. Closes #1137

2016-11-24proxy: Support HTTPS proxy and SOCKS+HTTP(s)Alex Rousskov
* HTTPS proxies: An HTTPS proxy receives all transactions over an SSL/TLS connection. Once a secure connection with the proxy is established, the user agent uses the proxy as usual, including sending CONNECT requests to instruct the proxy to establish a [usually secure] TCP tunnel with an origin server. HTTPS proxies protect nearly all aspects of user-proxy communications as opposed to HTTP proxies that receive all requests (including CONNECT requests) in vulnerable clear text. With HTTPS proxies, it is possible to have two concurrent _nested_ SSL/TLS sessions: the "outer" one between the user agent and the proxy and the "inner" one between the user agent and the origin server (through the proxy). This change adds supports for such nested sessions as well. A secure connection with a proxy requires its own set of the usual SSL options (their actual descriptions differ and need polishing, see TODO): --proxy-cacert FILE CA certificate to verify peer against --proxy-capath DIR CA directory to verify peer against --proxy-cert CERT[:PASSWD] Client certificate file and password --proxy-cert-type TYPE Certificate file type (DER/PEM/ENG) --proxy-ciphers LIST SSL ciphers to use --proxy-crlfile FILE Get a CRL list in PEM format from the file --proxy-insecure Allow connections to proxies with bad certs --proxy-key KEY Private key file name --proxy-key-type TYPE Private key file type (DER/PEM/ENG) --proxy-pass PASS Pass phrase for the private key --proxy-ssl-allow-beast Allow security flaw to improve interop --proxy-sslv2 Use SSLv2 --proxy-sslv3 Use SSLv3 --proxy-tlsv1 Use TLSv1 --proxy-tlsuser USER TLS username --proxy-tlspassword STRING TLS password --proxy-tlsauthtype STRING TLS authentication type (default SRP) All --proxy-foo options are independent from their --foo counterparts, except --proxy-crlfile which defaults to --crlfile and --proxy-capath which defaults to --capath. Curl now also supports %{proxy_ssl_verify_result} --write-out variable, similar to the existing %{ssl_verify_result} variable. Supported backends: OpenSSL, GnuTLS, and NSS. * A SOCKS proxy + HTTP/HTTPS proxy combination: If both --socks* and --proxy options are given, Curl first connects to the SOCKS proxy and then connects (through SOCKS) to the HTTP or HTTPS proxy. TODO: Update documentation for the new APIs and --proxy-* options. Look for "Added in 7.XXX" marks.
2016-11-18lib: fix compiler warnings after de4de4e3c7cMarcel Raad
Visual C++ now complains about implicitly casting time_t (64-bit) to long (32-bit). Fix this by changing some variables from long to time_t, or explicitly casting to long where the public interface would be affected. Closes #1131
