2019-05-01cookie: Guard against possible NULL ptr derefDaniel Gustafsson
In case the name pointer isn't set (due to memory pressure most likely) we need to skip the prefix matching and reject with a badcookie to avoid a possible NULL pointer dereference. Closes #3820 #3821 Reported-by: Jonathan Moerman Reviewed-by: Daniel Stenberg <daniel@haxx.se>
2019-04-29nss: provide more specific error messages on failed initKamil Dudka
Closes #3808
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
2019-04-27cmake: rename CMAKE_USE_DARWINSSL to CMAKE_USE_SECTRANSPSimon Warta
Closes https://github.com/curl/curl/pull/3769
2019-04-23ntlm: Missed pre-processor || (or) during rebase for cd15acd0Steve Holme
2019-04-23ntlm: Support the NT response in the type-3 when OpenSSL doesn't include MD4Steve Holme
Just like we do for mbed TLS, use our local implementation of MD4 when OpenSSL doesn't support it. This allows a type-3 message to include the NT response.
2019-04-22sasl: Don't send authcid as authzid for the PLAIN mechanism as per RFC 4616Steve Holme
RFC 4616 specifies the authzid is optional in the client authentication message and that the server will derive the authorisation identity (authzid) from the authentication identity (authcid) when not specified by the client.
2019-04-22memdebug: fix variable nameGisle Vanem

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
2019-04-20altsvc: Fix building with cookies disablesPo-Chuan Hsieh
ALTSVC requires Curl_get_line which is defined in lib/cookie.c inside a #if check of HTTP and COOKIES. That makes Curl_get_line undefined if COOKIES is disabled. Fix by splitting out the function into a separate file which can be included where needed. Closes #3717 Reviewed-by: Daniel Gustafsson <daniel@yesql.se> Reviewed-by: Marcel Raad <Marcel.Raad@teamviewer.com>
2019-04-20Curl_disconnect: treat all CONNECT_ONLY connections as "dead"Daniel Stenberg
Since the connection has been used by the "outside" we don't know the state of it anymore and curl should not use it anymore. Bug: https://curl.haxx.se/mail/lib-2019-04/0052.html Closes #3795
2019-04-19multi: fix the statenames (follow-up fix from 2f44e94efb3df8e)Daniel Stenberg
The list of names must be in sync with the defined states in the header file!

2019-04-15md5: Return CURLcode from the internally accessible functionsSteve Holme
Following 28f826b3 to return CURLE_OK instead of numeric 0.
2019-04-14md(4|5): Fixed indentation oddities with the importation of replacement codeSteve Holme
The indentation from 211d5329 and 57d6d253 was a little strange as parts didn't align correctly, uses 4 spaces rather than 2. Checked the indentation of the original source so it aligns, albeit, using curl style.

To aid debugging better.
2019-04-13CURLOPT_ADDRESS_SCOPE: fix range check and moretmilburn
Commit 9081014 fixed most of the confusing issues between scope id and scope however 844896d added bad limits checking assuming that the scope is being set and not the scope id. I have fixed the documentation so it all refers to scope ids. In addition Curl_if2ip refered to the scope id as remote_scope_id which is incorrect, so I renamed it to local_scope_id. Adjusted-by: Daniel Stenberg Closes #3655 Closes #3765 Fixes #3713
2019-04-13urlapi: stricter CURLUPART_PORT parsingDaniel Stenberg
Only allow well formed decimal numbers in the input. Document that the number MUST be between 1 and 65535. Add tests to test 1560 to verify the above. Ref: https://github.com/curl/curl/issues/3753 Closes #3762
2019-04-12openssl: mark connection for close on TLS close_notifyDaniel Stenberg
Without this, detecting and avoid reusing a closed TLS connection (without a previous GOAWAY) when doing HTTP/2 is tricky. Reported-by: Tom van der Woerdt Fixes #3750 Closes #3763
2019-04-11vauth/cleartext: Update the PLAIN login function signature to match RFC 4616Steve Holme
Functionally this doesn't change anything as we still use the username for both the authorisation identity and the authentication identity. Closes #3757

2019-04-11polarssl_threadlock: remove conditionally unused codeMarcel Raad
Make functions no-ops if neither both USE_THREADS_POSIX and HAVE_PTHREAD_H nor both USE_THREADS_WIN32 and HAVE_PROCESS_H are defined. Previously, if only one of them was defined, there was either code compiled that did nothing useful or the wrong header included for the functions used. Also, move POLARSSL_MUTEX_T define to implementation file as it's not used externally. Closes https://github.com/curl/curl/pull/3739

2019-04-04smtp: fix compiler warningRikard Falkeborn
- Fix clang string-plus-int warning. Clang 8 warns about adding a string to an int does not append to the string. Indeed it doesn't, but that was not the intention either. Use array indexing as suggested to silence the warning. There should be no functional changes. (In other words clang warns about "foo"+2 but not &"foo"[2] so use the latter.) smtp.c:1221:29: warning: adding 'int' to a string does not append to the string [-Wstring-plus-int] eob = strdup(SMTP_EOB + 2); ~~~~~~~~~~~~~~~~^~~~ Closes https://github.com/curl/curl/pull/3729

2019-03-15configure: add --with-amisslChris Young
AmiSSL is an Amiga native library which provides a wrapper over OpenSSL.

Configure will now check for the headers and ensure they are included if found. Closes #3677
