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.

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.
2015-03-16Bug #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.

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.

2014-02-13Curl_urldecode: don't allow NULL as receiverDaniel Stenberg
For a function that returns a decoded version of a string, it seems really strange to allow a NULL pointer to get passed in which then prevents the decoded data from being returned! This functionality was not documented anywhere either. If anyone would use it that way, that memory would've been leaked. Bug: https://github.com/bagder/curl/pull/90 Reported-by: Arvid Norberg
2013-06-22Curl_urldecode: no peeking beyond end of input bufferDaniel Stenberg
Security problem: CVE-2013-2174 If a program would give a string like "%FF" to curl_easy_unescape() but ask for it to decode only the first byte, it would still parse and decode the full hex sequence. The function then not only read beyond the allowed buffer but it would also deduct the *unsigned* counter variable for how many more bytes there's left to read in the buffer by two, making the counter wrap. Continuing this, the function would go on reading beyond the buffer and soon writing beyond the allocated target buffer... Bug: http://curl.haxx.se/docs/adv_20130622.html Reported-by: Timo Sirainen
2013-01-09build: fix circular header inclusion with other packagesYang Tse
This commit renames lib/setup.h to lib/curl_setup.h and renames lib/setup_once.h to lib/curl_setup_once.h. Removes the need and usage of a header inclusion guard foreign to libcurl. [1] Removes the need and presence of an alarming notice we carried in old setup_once.h [2] ---------------------------------------- 1 - lib/setup_once.h used __SETUP_ONCE_H macro as header inclusion guard up to commit ec691ca3 which changed this to HEADER_CURL_SETUP_ONCE_H, this single inclusion guard is enough to ensure that inclusion of lib/setup_once.h done from lib/setup.h is only done once. Additionally lib/setup.h has always used __SETUP_ONCE_H macro to protect inclusion of setup_once.h even after commit ec691ca3, this was to avoid a circular header inclusion triggered when building a c-ares enabled version with c-ares sources available which also has a setup_once.h header. Commit ec691ca3 exposes the real nature of __SETUP_ONCE_H usage in lib/setup.h, it is a header inclusion guard foreign to libcurl belonging to c-ares's setup_once.h The renaming this commit does, fixes the circular header inclusion, and as such removes the need and usage of a header inclusion guard foreign to libcurl. Macro __SETUP_ONCE_H no longer used in libcurl. 2 - Due to the circular interdependency of old lib/setup_once.h and the c-ares setup_once.h header, old file lib/setup_once.h has carried back from 2006 up to now days an alarming and prominent notice about the need of keeping libcurl's and c-ares's setup_once.h in sync. Given that this commit fixes the circular interdependency, the need and presence of mentioned notice is removed. All mentioned interdependencies come back from now old days when the c-ares project lived inside a curl subdirectory. This commit removes last traces of such fact.

2012-01-24URL sanitize: reject URLs containing bad dataDaniel Stenberg
Protocols (IMAP, POP3 and SMTP) that use the path part of a URL in a decoded manner now use the new Curl_urldecode() function to reject URLs with embedded control codes (anything that is or decodes to a byte value less than 32). URLs containing such codes could easily otherwise be used to do harm and allow users to do unintended actions with otherwise innocent tools and applications. Like for example using a URL like pop3://pop3.example.com/1%0d%0aDELE%201 when the app wants a URL to get a mail and instead this would delete one. This flaw is considered a security vulnerability: CVE-2012-0036 Security advisory at: http://curl.haxx.se/docs/adv_20120124.html Reported by: Dan Fandrich

2006-10-17Avoid typecasting a signed char to an int when using is*() functions, as thatDaniel Stenberg
could very well cause a negate number get passed in and thus cause reading outside of the array usually used for this purpose. We avoid this by using the uppercase macro versions introduced just now that does some extra crazy typecasts to avoid byte codes > 127 to cause negative int values.
