2020-01-29cookie: check __Secure- and __Host- case sensitivelyDaniel Stenberg
While most keywords in cookies are case insensitive, these prefixes are specified explicitly to get checked "with a case-sensitive match". (From the 6265bis document in progress) Ref: https://tools.ietf.org/html/draft-ietf-httpbis-rfc6265bis-04 Closes #4864
2019-12-01build: Disable Visual Studio warning "conditional expression is constant"Jay Satiro
- Disable warning C4127 "conditional expression is constant" globally in curl_setup.h for when building with Microsoft's compiler. This mainly affects building with the Visual Studio project files found in the projects dir. Prior to this change the cmake and winbuild build systems already disabled 4127 globally for when building with Microsoft's compiler. Also, 4127 was already disabled for all build systems in the limited circumstance of the WHILE_FALSE macro which disabled the warning specifically for while(0). This commit removes the WHILE_FALSE macro and all other cruft in favor of disabling globally in curl_setup. Background: We have various macros that cause 0 or 1 to be evaluated, which would cause warning C4127 in Visual Studio. For example this causes it: #define Curl_resolver_asynch() 1 Full behavior is not clearly defined and inconsistent across versions. However it is documented that since VS 2015 Update 3 Microsoft has addressed this somewhat but not entirely, not warning on while(true) for example. Prior to this change some C4127 warnings occurred when I built with Visual Studio using the generated projects in the projects dir. Closes https://github.com/curl/curl/pull/4658
2019-11-29parsedate: offer a getdate_capped() alternativeDaniel Stenberg
... and use internally. This function will return TIME_T_MAX instead of failure if the parsed data is found to be larger than what can be represented. TIME_T_MAX being the largest value curl can represent. Reviewed-by: Daniel Gustafsson Reported-by: JanB on github Fixes #4152 Closes #4651
2019-11-28curl_setup_once: consistently use WHILE_FALSE in macrosDaniel Gustafsson
The WHILE_FALSE construction is used to avoid compiler warnings in macro constructions. This fixes a few instances where it was not used in order to keep the code consistent. Closes #4649 Reviewed-by: Daniel Stenberg <daniel@haxx.se>
2019-10-03cookies: change argument type for Curl_flush_cookiesDaniel Stenberg
The second argument is really a 'bool' so use that and pass in TRUE/FALSE to make it clear. Closes #4455
2019-10-03cookie: avoid harmless use after freePaul Dreik
This fix removes a use after free which can be triggered by the internal cookie fuzzer, but otherwise is probably impossible to trigger from an ordinary application. The following program reproduces it: curl_global_init(CURL_GLOBAL_DEFAULT); CURL* handle=curl_easy_init(); CookieInfo* info=Curl_cookie_init(handle,NULL,NULL,false); curl_easy_setopt(handle, CURLOPT_COOKIEJAR, "/dev/null"); Curl_flush_cookies(handle, true); Curl_cookie_cleanup(info); curl_easy_cleanup(handle); curl_global_cleanup(); This was found through fuzzing. Closes #4454
2019-09-28cookies: using a share with cookies shouldn't enable the cookie engineDaniel Stenberg
The 'share object' only sets the storage area for cookies. The "cookie engine" still needs to be enabled or activated using the normal cookie options. This caused the curl command line tool to accidentally use cookies without having been told to, since curl switched to using shared cookies in 7.66.0. Test 1166 verifies Updated test 506 Fixes #4429 Closes #4434
2019-09-21cookie: pass in the correct cookie amount to qsort()Daniel Stenberg
As the loop discards cookies without domain set. This bug would lead to qsort() trying to sort uninitialized pointers. We have however not found it a security problem. Reported-by: Paul Dreik Closes #4386
2019-07-19source: remove names from source commentsDaniel Stenberg
Several reasons: - we can't add everyone who's helping out so its unfair to just a few selected ones. - we already list all helpers in THANKS and in RELEASE-NOTES for each release - we don't want to give the impression that some parts of the code is "owned" or "controlled" by specific persons Assisted-by: Daniel Gustafsson Closes #4129
2019-07-06lib: Use UTF-8 encoding in commentsGergely Nagy
Some editors and IDEs assume that source files use UTF-8 file encodings. It also fixes the build with MSVC when /utf-8 command line option is used (this option is mandatory for some other open-source projects, this is useful when using the same options is desired for building all libraries of a project).

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>
2019-04-20altsvc: 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.

2019-02-27cookies: only save the cookie file if the engine is enabledDaniel Stenberg
Follow-up to 8eddb8f4259. If the cookieinfo pointer is NULL there really is nothing to save. Without this fix, we got a problem when a handle was using shared object with cookies and is told to "FLUSH" it to file (which worked) and then the share object was removed and when the easy handle was closed just afterwards it has no cookieinfo and no cookies so it decided to save an empty jar (overwriting the file just flushed). Test 1905 now verifies that this works. Assisted-by: Michael Wallner Assisted-by: Marcel Raad Closes #3621

2019-02-17cookie: Add support for cookie prefixesDaniel Gustafsson
The draft-ietf-httpbis-rfc6265bis-02 draft, specify a set of prefixes and how they should affect cookie initialization, which has been adopted by the major browsers. This adds support for the two prefixes defined, __Host- and __Secure, and updates the testcase with the supplied examples from the draft. Closes #3554 Reviewed-by: Daniel Stenberg <daniel@haxx.se>

2018-12-19cookies: extend domain checks to non psl buildsDaniel Gustafsson

2018-12-13cookies: leave secure cookies aloneDaniel Gustafsson
Only allow secure origins to be able to write cookies with the 'secure' flag set. This reduces the risk of non-secure origins to influence the state of secure origins.

2018-09-10cookies: Move failure case label to end of functionDaniel Gustafsson
Rather than jumping backwards to where failure cleanup happens to be performed, move the failure case to end of the function where it is expected per existing coding convention. Closes #2965
2018-09-10cookies: fix leak when writing cookies to fileDaniel Gustafsson
If the formatting fails, we error out on a fatal error and clean up on the way out. The array was however freed within the wrong scope and was thus never freed in case the cookies were written to a file instead of STDOUT. Closes #2957
2018-09-10cookies: Remove redundant expired checkDaniel Gustafsson
Expired cookies have already been purged at a later expiration time before this check, so remove the redundant check. closes #2962

2018-08-31cookies: support creation-time attribute for cookiesDaniel Gustafsson
According to RFC6265 section 5.4, cookies with equal path lengths SHOULD be sorted by creation-time (earlier first). This adds a creation-time record to the cookie struct in order to make cookie sorting more deterministic. The creation-time is defined as the order of the cookies in the jar, the first cookie read fro the jar being the oldest. The creation-time is thus not serialized into the jar. Also remove the strcmp() matching in the sorting as there is no lexicographic ordering in RFC6265. Existing tests are updated to match. Closes #2524

2018-05-13cookies: do not take cookie name as a parameterPatrick Monnerat
RFC 6265 section 4.2.1 does not set restrictions on cookie names. This is a follow-up to commit 7f7fcd0. Also explicitly check proper syntax of cookie name/value pair. New test 1155 checks that cookie names are not reserved words. Reported-By: anshnd at github Fixes #2564 Closes #2566
2018-04-25cookies: ensure that we have cookies before writing jarDaniel Gustafsson
The jar should be written iff there are cookies, so ensure that we still have cookies after expiration to avoid creating an empty file. Closes #2529

This is also what browsers seem to implement. We now allow max 5000 bytes cookie header. Max 4095 bytes length per cookie name and value. Name + value together may not exceed 4096 bytes.
