2019-09-09tftp: Alloc maximum blksize, and use default unless OACK is receivedThomas Vegas
Fixes potential buffer overflow from 'recvfrom()', should the server return an OACK without blksize. Bug: https://curl.haxx.se/docs/CVE-2019-5482.html CVE-2019-5482
2019-09-09tftp: return error when packet is too small for optionsThomas Vegas
2019-07-30cleanup: remove the 'numsocks' argument used in many placesDaniel Stenberg
It was used (intended) to pass in the size of the 'socks' array that is also passed to these functions, but was rarely actually checked/used and the array is defined to a fixed size of MAX_SOCKSPEREASYHANDLE entries that should be used instead. Closes #4169
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
2019-05-20tftp: use the current blksize for recvfrom()Daniel Stenberg
bug: https://curl.haxx.se/docs/CVE-2019-5436.html Reported-by: l00p3r on hackerone CVE-2019-5436
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
2019-02-26strerror: 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
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
2018-09-22url: use the URL API internally as wellDaniel Stenberg
... to make it a truly unified URL parser. Closes #3017
2018-09-01all: s/int/size_t cleanupDaniel Stenberg
Assisted-by: Rikard Falkeborn Closes #2922
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
2018-05-22tftp: make sure error is zero terminated before printfing itDaniel Stenberg
2018-04-07curl_setup: provide a CURL_SA_FAMILY_T type if none existsDaniel Stenberg
... and use this type instead of 'sa_family_t' in the code since several platforms don't have it. Closes #2463
2018-04-07build: add picky compiler warning flags for gcc 6 and 7Eric Gallager
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
2017-09-11code style: use spaces around plusesDaniel Stenberg
2017-09-11code style: use spaces around equals signsDaniel Stenberg

2017-08-07tftp: reject file name lengths that don't fitDaniel Stenberg
... and thereby avoid telling send() to send off more bytes than the size of the buffer! CVE-2017-1000100 Bug: https://curl.haxx.se/docs/adv_20170809B.html Reported-by: Even Rouault Credit to OSS-Fuzz for the discovery
2017-07-31libcurl: Stop using error codes defined under CURL_NO_OLDIESDwarakanath Yadavalli
Fixes https://github.com/curl/curl/issues/1688 Closes https://github.com/curl/curl/pull/1712
2017-06-30handler: refactor connection checkingMax Dymond
Add a new type of callback to Curl_handler which performs checks on the connection. Alter RTSP so that it uses this callback to do its own check on connection health.
2017-05-07tftp: silence bad-function-cast warningMarcel Raad
The cases this warns about are handled elsewhere, so just use an intermediate variable to silence the warning.
2017-03-13Improve code readbilitySylvestre Ledru
... by removing the else branch after a return, break or continue. Closes #1310
2016-12-13checksrc: stricter no-space-before-paren enforcementDaniel Stenberg
In order to make the code style more uniform everywhere
2016-11-24checksrc: code style: use 'char *name' styleDaniel Stenberg
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
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.
2016-10-31escape: avoid using curl_easy_unescape() internallyDaniel Stenberg
Since the internal Curl_urldecode() function has a better API.
2016-10-18select: switch to macros in uppercaseDaniel Stenberg
Curl_select_ready() was the former API that was replaced with Curl_select_check() a while back and the former arg setup was provided with a define (in order to leave existing code unmodified). Now we instead offer SOCKET_READABLE and SOCKET_WRITABLE for the most common shortcuts where only one socket is checked. They're also more visibly macros.
2016-08-04TFTP: Fix upload problem with piped inputSerj Kalichev
When input stream for curl is stdin and input stream is not a file but generated by a script then curl can truncate data transfer to arbitrary size since a partial packet is treated as end of transfer by TFTP. Fixes #857
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
2016-04-03code: style updatesDaniel Stenberg
2016-02-23TFTP: add option to suppress TFTP option requests (Part 2)Jay Satiro
- Add tests. - Add an example to CURLOPT_TFTP_NO_OPTIONS.3. - Add --tftp-no-options to expose CURLOPT_TFTP_NO_OPTIONS. Bug: https://github.com/curl/curl/issues/481
2016-02-23TFTP: add option to suppress TFTP option requests (Part 1)Michael Koenig
Some TFTP server implementations ignore the "TFTP Option extension" (RFC 1782-1784, 2347-2349), or implement it in a flawed way, causing problems with libcurl. Another switch for curl_easy_setopt "CURLOPT_TFTP_NO_OPTIONS" is introduced which prevents libcurl from sending TFTP option requests to a server, avoiding many problems caused by faulty implementations. Bug: https://github.com/curl/curl/issues/481
2016-02-03URLs: change all http:// URLs to https://Daniel Stenberg
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.
2015-03-17checksrc: detect and remove space before trailing semicolonsDaniel Stenberg
2015-03-17checksrc: use space before paren in "return (expr);"Daniel Stenberg
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.
2015-03-03mprintf.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.
2015-02-05ftp: Use 'CURLcode result' for curl result codesSteve Holme
2014-10-24code cleanup: we prefer 'CURLcode result'Daniel Stenberg
... for the local variable name in functions holding the return code. Using the same name universally makes code easier to read and follow. Also, unify code for checking for CURLcode errors with: if(result) or if(!result) instead of if(result == CURLE_OK), if(CURLE_OK == result) or if(result != CURLE_OK)
2014-05-22bits.close: introduce connection close trackingDaniel Stenberg
Make all code use connclose() and connkeep() when changing the "close state" for a connection. These two macros take a string argument with an explanation, and debug builds of curl will include that in the debug output. Helps tracking connection re-use/close issues.
2014-04-26INFILESIZE: fields in UserDefined must not be changed run-timeDaniel Stenberg
set.infilesize in this case was modified in several places, which could lead to repeated requests using the same handle to get unintendent/wrong consequences based on what the previous request did!
2014-04-18tftp.c: fix possible dereference of null pointerMarc Hoersken
2014-01-28TFTP: fix crash on time-outDaniel Stenberg
tftp_done() can get called with its TFTP state pointer still being NULL on an early time-out, which caused a segfault when dereferenced. Reported-by: Glenn Sheridan Bug: http://curl.haxx.se/mail/lib-2014-01/0246.html
2013-12-31mprintf: Replaced internal usage of FORMAT_OFF_T and FORMAT_OFF_TUSteve Holme
Following commit 0aafd77fa4c6f2, replaced the internal usage of FORMAT_OFF_T and FORMAT_OFF_TU with the external versions that we expect API programmers to use. This negates the need for separate definitions which were subtly different under different platforms/compilers.
2013-12-07TFTP: let tftp_multi_statemach()'s return codes throughJames Dury
It would otherwise always clobber the return code with new function calls and it couldn't return timeout etc. Bug: http://curl.haxx.se/bug/view.cgi?id=1310
