2018-05-28psl: use latest psl and refresh it periodicallyPatrick Monnerat
The latest psl is cached in the multi or share handle. It is refreshed before use after 72 hours. New share lock CURL_LOCK_DATA_PSL controls the psl cache sharing. If the latest psl is not available, the builtin psl is used. Reported-by: Yaakov Selkowitz Fixes #2553 Closes #2601
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
2018-04-06hash: calculate sizes with size_t instead of longsDaniel Stenberg
... since they return size_t anyway! closes #2462
2018-04-06cookie: case-insensitive hashing for the domainsLauri Kasanen
closes #2458
2018-04-04cookie: fix and optimize 2nd top level domain name extractionPatrick Monnerat
This fixes a segfault occurring when a name of the (invalid) form "domain..tld" is processed. test46 updated to cover this case. Follow-up to commit c990ead. Ref: https://github.com/curl/curl/pull/2440
2018-04-02cookie: store cookies per top-level-domain-specific hash tableLauri Kasanen
This makes libcurl handle thousands of cookies much better and speedier. Closes #2440
2018-04-02cookies: when reading from a file, only remove_expired onceLauri Kasanen
This drops the cookie load time for 8k cookies from 178ms to 15ms. Closes #2441
2018-01-25cookies: remove verbose "cookie size:" outputDaniel Stenberg
It was once used for some debugging/verifying logic but should never have ended up in git!
2017-10-31cookie: avoid NULL dereferenceDaniel Stenberg
... when expiring old cookies. Reported-by: Pavel Gushchin Fixes #2032 Closes #2035
2017-09-30cookie: fix memory leak if path was set twice in headerDaniel Stenberg
... this will let the second occurance override the first. Added test 1161 to verify. Reported-by: Max Dymond Fixes #1932 Closes #1933
2017-09-29cookie: fix memory leak on oversized rejectionDaniel Stenberg
Regression brought by 2bc230de63b Detected by OSS-fuzz: https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=3513 Assisted-by: Max Dymond Closes #1930
2017-09-19cookies: use lock when using CURLINFO_COOKIELISTPavel P
Closes #1896
2017-09-18cookies: reject oversized cookiesDaniel Stenberg
... instead of truncating them. There's no fixed limit for acceptable cookie names in RFC 6265, but the entire cookie is said to be less than 4096 bytes (section 6.1). 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. Added test 1151 to verify Bug: https://curl.haxx.se/mail/lib-2017-09/0062.html Reported-by: Kevin Smith Closes #1894
2017-09-11code style: use spaces around plusesDaniel Stenberg
2017-09-11code style: use spaces around equals signsDaniel Stenberg
2017-08-14strtoofft: reduce integer overflow risks globallyDaniel Stenberg
... make sure we bail out on overflows. Reported-by: Brian Carpenter Closes #1758
2017-03-13Improve code readbilitySylvestre Ledru
... by removing the else branch after a return, break or continue. Closes #1310
2017-02-21cookie: fix declaration of 'dup' shadows a global declarationDaniel Stenberg
2017-01-27cookies: do not assume a valid domain has a dotDaniel Stenberg
This repairs cookies for localhost. Non-PSL builds will now only accept "localhost" without dots, while PSL builds okeys everything not listed as PSL. Added test 1258 to verify. This was a regression brought in a76825a5efa6b4
2016-12-14checksrc: warn for assignments within if() expressionsDaniel Stenberg
... they're already frowned upon in our source code style guide, this now enforces the rule harder.
2016-11-24checksrc: code style: use 'char *name' styleDaniel Stenberg
2016-10-31cookie: replace use of fgets() with custom versionDaniel Stenberg
... that will ignore lines that are too long to fit in the buffer. CVE-2016-8615 Bug: https://curl.haxx.se/docs/adv_20161102A.html Reported-by: Cure53
2016-10-31strcasecompare: all case insensitive string compares ignore locale nowDaniel Stenberg
We had some confusions on when each function was used. We should not act differently on different locales anyway.
2016-10-31strcasecompare: is the new name for strequal()Daniel Stenberg
... to make it less likely that we forget that the function actually does case insentive compares. Also replaced several invokes of the function with a plain strcmp when case sensitivity is not an issue (like comparing with "-").
2016-10-31cookies: getlist() now holds deep copies of all cookiesDaniel Stenberg
Previously it only held references to them, which was reckless as the thread lock was released so the cookies could get modified by other handles that share the same cookie jar over the share interface. CVE-2016-8623 Bug: https://curl.haxx.se/docs/adv_20161102I.html Reported-by: Cure53
2016-10-03cookies: same domain handling changed to match browser behaviorSergei Kuzmin
Cokie with the same domain but different tailmatching property are now considered different and do not replace each other. If header contains following lines then two cookies will be set: Set-Cookie: foo=bar; domain=.foo.com; expires=Thu Mar 3 GMT 8:56:27 2033 Set-Cookie: foo=baz; domain=foo.com; expires=Thu Mar 3 GMT 8:56:27 2033 This matches Chrome, Opera, Safari, and Firefox behavior. When sending stored tokens to foo.com Chrome, Opera, Firefox store send them in the stored order, while Safari pre-sort the cookies. Closes #1050
2016-07-13cookie.c: Fix misleading indentationViktor Szakats
Closes https://github.com/curl/curl/pull/911
2016-06-22internals: rename the SessionHandle struct to Curl_easyDaniel Stenberg
2016-04-29lib: include curl_printf.h as one of the last headersDaniel Stenberg
curl_printf.h defines printf to curl_mprintf, etc. This can cause problems with external headers which may use __attribute__((format(printf, ...))) markers etc. To avoid that they cause problems with system includes, we include curl_printf.h after any system headers. That makes the three last headers to always be, and we keep them in this order: curl_printf.h curl_memory.h memdebug.h None of them include system headers, they all do funny #defines. Reported-by: David Benjamin Fixes #743
2016-03-10cookies: first n/v pair in Set-Cookie: is the cookie, then parametersDaniel Stenberg
RFC 6265 section 4.1.1 spells out that the first name/value pair in the header is the actual cookie name and content, while the following are the parameters. libcurl previously had a more liberal approach which causes significant problems when introducing new cookie parameters, like the suggested new cookie priority draft. The previous logic read all n/v pairs from left-to-right and the first name used that wassn't a known parameter name would be used as the cookie name, thus accepting "Set-Cookie: Max-Age=2; person=daniel" to be a cookie named 'person' while an RFC 6265 compliant parser should consider that to be a cookie named 'Max-Age' with an (unknown) parameter 'person'. Fixes #709
2016-03-08cookie: do not refuse cookies for localhostTim Rühsen
Closes #658
2016-03-05cookie: Don't expire session cookies in remove_expiredJay Satiro
Prior to this change cookies with an expiry date that failed parsing and were converted to session cookies could be purged in remove_expired. Bug: https://github.com/curl/curl/issues/697 Reported-by: Seth Mos
2016-03-03cookie: remove redundant checkDaniel Stenberg
... as it was already checked previously within the function. Reported-by: Dmitry-Me Closes #695
2016-02-08cookies: allow spaces in cookie names, cut of trailing spacesDaniel Stenberg
It turns out Firefox and Chrome both allow spaces in cookie names and there are sites out there using that. Turned out the code meant to strip off trailing space from cookie names didn't work. Fixed now. Test case 8 modified to verify both these changes. Closes #639
2016-02-03URLs: change all http:// URLs to https://Daniel Stenberg
2015-10-17cookies: Add support for Mozilla's Publix Suffix ListTim Rühsen
Use libpsl to check the domain value of Set-Cookie headers (and cookie jar entries) for not being a Publix Suffix. The configure script checks for "libpsl" by default. Disable the check with --without-libpsl. Ref: https://publicsuffix.org/ Ref: https://github.com/publicsuffix/list Ref: https://github.com/rockdaboot/libpsl
2015-06-18cookie: Fix bug in export if any-domain cookie is presentJay Satiro
In 3013bb6 I had changed cookie export to ignore any-domain cookies, however the logic I used to do so was incorrect, and would lead to a busy loop in the case of exporting a cookie list that contained any-domain cookies. The result of that is worse though, because in that case the other cookies would not be written resulting in an empty file once the application is terminated to stop the busy loop.
2015-06-03cookie: Stop exporting any-domain cookiesJay Satiro
Prior to this change any-domain cookies (cookies without a domain that are sent to any domain) were exported with domain name "unknown". Bug: https://github.com/bagder/curl/issues/292
2015-06-01curl_setup: Add macros for FOPEN_READTEXT, FOPEN_WRITETEXTJay Satiro
- Change fopen calls to use FOPEN_READTEXT instead of "r" or "rt" - Change fopen calls to use FOPEN_WRITETEXT instead of "w" or "wt" This change is to explicitly specify when we need to read/write text. Unfortunately 't' is not part of POSIX fopen so we can't specify it directly. Instead we now have FOPEN_READTEXT, FOPEN_WRITETEXT. Prior to this change we had an issue on Windows if an application that uses libcurl overrides the default file mode to binary. The default file mode in Windows is normally text mode (translation mode) and that's what libcurl expects. Bug: https://github.com/bagder/curl/pull/258#issuecomment-107093055 Reported-by: Orgad Shaneh
2015-04-21cookie: cookie parser out of boundary memory accessDaniel Stenberg
The internal libcurl function called sanitize_cookie_path() that cleans up the path element as given to it from a remote site or when read from a file, did not properly validate the input. If given a path that consisted of a single double-quote, libcurl would index a newly allocated memory area with index -1 and assign a zero to it, thus destroying heap memory it wasn't supposed to. CVE-2015-3145 Bug: http://curl.haxx.se/docs/adv_20150422C.html Reported-by: Hanno Böck
2015-04-01cookie: handle spaces after the name in Set-CookieDaniel Stenberg
"name =value" is fine and the space should just be skipped. Updated test 31 to also test for this. Bug: https://github.com/bagder/curl/issues/195 Reported-by: cromestant Help-by: Frank Gevaerts
2015-03-24curl_memory: make curl_memory.h the second-last header file loadedDan Fandrich
This header file must be included after all header files except memdebug.h, as it does similar memory function redefinitions and can be similarly affected by conflicting definitions in system or dependent library headers.
2015-03-16free: instead of Curl_safefree()Daniel Stenberg
Since we just started make use of free(NULL) in order to simplify code, this change takes it a step further and: - converts lots of Curl_safefree() calls to good old free() - makes Curl_safefree() not check the pointer before free() The (new) rule of thumb is: if you really want a function call that frees a pointer and then assigns it to NULL, then use Curl_safefree(). But we will prefer just using free() from now on.
2015-03-16Bug #149: Deletion of unnecessary checks before calls of the function "free"Markus Elfring
The function "free" is documented in the way that no action shall occur for a passed null pointer. It is therefore not needed that a function caller repeats a corresponding check. http://stackoverflow.com/questions/18775608/free-a-null-pointer-anyway-or-check-first This issue was fixed by using the software Coccinelle 1.0.0-rc24. Signed-off-by: Markus Elfring <elfring@users.sourceforge.net>
2015-03-03mprintf.h: remove #ifdef CURLDEBUGDaniel Stenberg
... and as a consequence, introduce curl_printf.h with that re-define magic instead and make all libcurl code use that instead.
2014-12-09cookies: Improved OOM handling in cookiesDan Fandrich
This fixes the test 506 torture test. The internal cookie API really ought to be improved to separate cookie parsing errors (which may be ignored) with OOM errors (which should be fatal).
2014-12-07cookie.c: Refactored cleanup code to simplifyDan Fandrich
Also, fixed the outdated comments on the cookie API.
2014-09-10cookies: reject incoming cookies set for TLDsDaniel Stenberg
Test 61 was modified to verify this. CVE-2014-3620 Reported-by: Tim Ruehsen URL: http://curl.haxx.se/docs/adv_20140910B.html
2014-09-10cookies: only use full host matches for hosts used as IP addressTim Ruehsen
By not detecting and rejecting domain names for partial literal IP addresses properly when parsing received HTTP cookies, libcurl can be fooled to both send cookies to wrong sites and to allow arbitrary sites to set cookies for others. CVE-2014-3613 Bug: http://curl.haxx.se/docs/adv_20140910A.html
