2019-05-06ssh: define USE_SSH if SSH is enabled (any backend)Daniel Stenberg
Closes #3846
2019-05-01process_pending_handles: mark queued transfers as previously pendingDaniel Stenberg
With transfers being queued up, we only move one at a a time back to the CONNECT state but now we mark moved transfers so that when a moved transfer is confirmed "successful" (it connected) it will trigger the move of another pending transfer. Previously, it would otherwise wait until the transfer was done before doing this. This makes queued up pending transfers get processed (much) faster.
2019-04-29CURL_MAX_INPUT_LENGTH: largest acceptable string input sizeDaniel Stenberg
This limits all accepted input strings passed to libcurl to be less than CURL_MAX_INPUT_LENGTH (8000000) bytes, for these API calls: curl_easy_setopt() and curl_url_set(). The 8000000 number is arbitrary picked and is meant to detect mistakes or abuse, not to limit actual practical use cases. By limiting the acceptable string lengths we also reduce the risk of integer overflows all over. NOTE: This does not apply to `CURLOPT_POSTFIELDS`. Test 1559 verifies. Closes #3805
2019-04-21CURLOPT_MAXAGE_CONN: set the maximum allowed age for conn reuseDaniel Stenberg
... and disconnect too old ones instead of trying to reuse. Default max age is set to 118 seconds. Ref: #3722 Closes #3782
2019-04-11CURLOPT_DNS_USE_GLOBAL_CACHE: removeDaniel Stenberg
Remove the code too. The functionality has been disabled in code since 7.62.0. Setting this option will from now on simply be ignored and have no function. Closes #3654
2019-04-06pipelining: removedDaniel Stenberg
As previously planned and documented in DEPRECATE.md, all pipelining code is removed. Closes #3651
2019-03-27resolve: apply Happy Eyeballs philosophy to parallel c-ares queriesBrad Spencer
Closes #3699
2019-03-14Negotiate: fix for HTTP POST with NegotiateDominik Hölzl
* Adjusted unit tests 2056, 2057 * do not generally close connections with CURLAUTH_NEGOTIATE after every request * moved negotiatedata from UrlState to connectdata * Added stream rewind logic for CURLAUTH_NEGOTIATE * introduced negotiatedata::GSS_AUTHDONE and negotiatedata::GSS_AUTHSUCC * Consider authproblem state for CURLAUTH_NEGOTIATE * Consider reuse_forbid for CURLAUTH_NEGOTIATE * moved and adjusted negotiate authentication state handling from output_auth_headers into Curl_output_negotiate * Curl_output_negotiate: ensure auth done is always set * Curl_output_negotiate: Set auth done also if result code is GSS_S_CONTINUE_NEEDED/SEC_I_CONTINUE_NEEDED as this result code may also indicate the last challenge request (only works with disabled Expect: 100-continue and CURLOPT_KEEP_SENDING_ON_ERROR -> 1) * Consider "Persistent-Auth" header, detect if not present; Reset/Cleanup negotiate after authentication if no persistent authentication * apply changes introduced with #2546 for negotiate rewind logic Fixes #1261 Closes #1975
2019-03-03alt-svc: the libcurl bitsDaniel Stenberg
2019-03-01urldata: simplify bytecountersDaniel Stenberg
- no need to have them protocol specific - no need to set pointers to them with the Curl_setup_transfer() call - make Curl_setup_transfer() operate on a transfer pointer, not connection - switch some counters from long to the more proper curl_off_t type Closes #3627
2019-02-28Curl_easy: remove req.maxfd - never used!Daniel Stenberg
Introduced in 8b6314ccfb, but not used anymore in current code. Unclear since when. Closes #3626
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
2019-02-19connection: never reuse CONNECT_ONLY conectionsDaniel Stenberg
and make CONNECT_ONLY conections never reuse any existing ones either. Reported-by: Pavel Löbl Bug: https://curl.haxx.se/mail/lib-2019-02/0064.html Closes #3586
2019-02-14gssapi: fix deprecated header warningsDaniel Stenberg
Heimdal includes on FreeBSD spewed out lots of them. Less so now. Closes #3566
2019-02-12pretransfer: don't strlen() POSTFIELDS set for GET requestsDaniel Stenberg
... since that data won't be used in the request anyway. Fixes #3548 Reported-by: Renaud Allard Close #3549
2019-02-01spnego_sspi: add support for channel bindinggeorgeok
Attempt to add support for Secure Channel binding when negotiate authentication is used. The problem to solve is that by default IIS accepts channel binding and curl doesn't utilise them. The result was a 401 response. Scope affects only the Schannel(winssl)-SSPI combination. Fixes https://github.com/curl/curl/issues/3503 Closes https://github.com/curl/curl/pull/3509
2019-01-19ntlm_sspi: add support for channel bindinggeorgeok
Windows extended potection (aka ssl channel binding) is required to login to ntlm IIS endpoint, otherwise the server returns 401 responses. Fixes #3280 Closes #3321
2019-01-11urldata: rename easy_conn to just connDaniel Stenberg
We use "conn" everywhere to be a pointer to the connection. Introduces two functions that "attaches" and "detaches" the connection to and from the transfer. Going forward, we should favour using "data->conn" (since a transfer always only has a single connection or none at all) to "conn->data" (since a connection can have none, one or many transfers associated with it and updating conn->data to be correct is error prone and a frequent reason for internal issues). Closes #3442
2019-01-10multi: multiplexing improvementsDaniel Stenberg
Fixes #3436 Closes #3448 Problem 1 After LOTS of scratching my head, I eventually realized that even when doing 10 uploads in parallel, sometimes the socket callback to the application that tells it what to wait for on the socket, looked like it would reflect the status of just the single transfer that just changed state. Digging into the code revealed that this was indeed the truth. When multiple transfers are using the same connection, the application did not correctly get the *combined* flags for all transfers which then could make it switch to READ (only) when in fact most transfers wanted to get told when the socket was WRITEABLE. Problem 1b A separate but related regression had also been introduced by me when I cleared connection/transfer association better a while ago, as now the logic couldn't find the connection and see if that was marked as used by more transfers and then it would also prematurely remove the socket from the socket hash table even in times other transfers were still using it! Fix 1 Make sure that each socket stored in the socket hash has a "combined" action field of what to ask the application to wait for, that is potentially the ORed action of multiple parallel transfers. And remove that socket hash entry only if there are no transfers left using it. Problem 2 The socket hash entry stored an association to a single transfer using that socket - and when curl_multi_socket_action() was called to tell libcurl about activities on that specific socket only that transfer was "handled". This was WRONG, as a single socket/connection can be used by numerous parallel transfers and not necessarily a single one. Fix 2 We now store a list of handles in the socket hashtable entry and when libcurl is told there's traffic for a particular socket, it now iterates over all known transfers using that single socket.
2018-12-27hostip: support wildcard hostsClaes Jakobsson
This adds support for wildcard hosts in CURLOPT_RESOLVE. These are try-last so any non-wildcard entry is resolved first. If specified, any host not matched by another CURLOPT_RESOLVE config will use this as fallback. Example send a.com to 10.0.0.1 and everything else to 10.0.0.2: curl --resolve *:443:10.0.0.2 --resolve a.com:443:10.0.0.1 \ https://a.com https://b.com This is probably quite similar to using: --connect-to a.com:443:10.0.0.1:443 --connect-to :443:10.0.0.2:443 Closes #3406 Reviewed-by: Daniel Stenberg <daniel@haxx.se>
2018-12-21http: added options for allowing HTTP/0.9 responsesDaniel Stenberg
Added CURLOPT_HTTP09_ALLOWED and --http0.9 for this purpose. For now, both the tool and library allow HTTP/0.9 by default. docs/DEPRECATE.md lays out the plan for when to reverse that default: 6 months after the 7.64.0 release. The options are added already now so that applications/scripts can start using them already now. Fixes #2873 Closes #3383
2018-12-17pingpong: change default response timeout to 120 secondsDaniel Stenberg
Previously it was 30 minutes
2018-12-14http: Implement trailing headers for chunked transfersAyoub Boudhar
This adds the CURLOPT_TRAILERDATA and CURLOPT_TRAILERFUNCTION options that allow a callback based approach to sending trailing headers with chunked transfers. The test server (sws) was updated to take into account the detection of the end of transfer in the case of trailing headers presence. Test 1591 checks that trailing headers can be sent using libcurl. Closes #3350
2018-11-22host names: allow trailing dot in name resolve, then strip itTobias Hintze
Delays stripping of trailing dots to after resolving the hostname. Fixes #3022 Closes #3222

2018-08-18vtls: reinstantiate engine on duplicated handlesLaurent Bonnans
Handles created with curl_easy_duphandle do not use the SSL engine set up in the original handle.
