2013-08-20Curl_setopt: handle arbitrary-length username and passwordJonathan Nieder
libcurl truncates usernames, passwords, and options set with curl_easy_setopt to 255 (= MAX_CURL_PASSWORD_LENGTH - 1) characters. This doesn't affect the return value from curl_easy_setopt(), so from the caller's point of view, there is no sign anything strange has happened, except that authentication fails. For example: # Prepare a long (300-char) password. s=0123456789; s=$s$s$s$s$s$s$s$s$s$s; s=$s$s$s; # Start a server. nc -l -p 8888 | tee out & pid=$! # Tell curl to pass the password to the server. curl --user me:$s http://localhost:8888 & sleep 1; kill $pid # Extract the password. userpass=$( awk '/Authorization: Basic/ {print $3}' <out | tr -d '\r' | base64 -d ) password=${userpass#me:} echo ${#password} Expected result: 300 Actual result: 255 The fix is simple: allocate appropriately sized buffers on the heap instead of trying to squeeze the provided values into fixed-size on-stack buffers.

2013-08-20netrc: handle longer username and passwordJonathan Nieder
libcurl truncates usernames and passwords it reads from .netrc to LOGINSIZE and PASSWORDSIZE (64) characters without any indication to the user, to ensure the values returned from Curl_parsenetrc fit in a caller-provided buffer. Fix the interface by passing back dynamically allocated buffers allocated to fit the user's input. The parser still relies on a 256-character buffer to read each line, though. So now you can include an ~246-character password in your .netrc, instead of the previous limit of 63 characters. Reported-by: Colby Ranger
2013-08-20url: allocate username, password, and options on the heapJonathan Nieder
This makes it possible to increase the size of the buffers when needed in later patches. No functional change yet.
2013-08-20url: use goto in create_conn() for exception handlingJonathan Nieder
Instead of remembering before each "return" statement which temporary allocations, if any, need to be freed, take care to set pointers to NULL when no longer needed and use a goto to a common block to exit the function and free all temporaries. No functional change intended. Currently the only temporary buffer in this function is "proxy" which is already correctly freed when appropriate, but there will be more soon.
2013-08-20sasl: allow arbitrarily long username and passwordJonathan Nieder
Use appropriately sized buffers on the heap instead of fixed-size buffers on the stack, to allow for longer usernames and passwords. Callers never pass anything longer than MAX_CURL_USER_LENGTH (resp. MAX_CURL_PASSWORD_LENGTH), so no functional change inteded yet.
2013-08-19imap: Fixed response check for SEARCH commandAlex McLellan
Adding this line allows libcurl to return the server response when performing a search command via a custom request.

This makes the socket callback get called with the proper bitmask as otherwise the application could be left hanging waiting for reading on an upload connection! Bug: http://curl.haxx.se/mail/lib-2013-08/0043.html Reported-by: Bill Doyle

2013-08-12multi: s/easy/dataDaniel Stenberg
With everything being struct SessionHandle pointers now, this rename makes multi.c use the library-wide practise of calling that pointer 'data' instead of the previously used 'easy'.
2013-08-12cleanup: removed one function, made one staticDaniel Stenberg
Moved Curl_easy_addmulti() from easy.c to multi.c, renamed it to easy_addmulti and made it static. Removed Curl_easy_initHandleData() and uses of it since it was emptied in commit cdda92ab67b47d74a.
2013-08-12SessionHandle: the protocol specific pointer is now a void *Daniel Stenberg
All protocol handler structs are now opaque (void *) in the SessionHandle struct and moved in the request-specific sub-struct 'SingleRequest'. The intension is to keep the protocol specific knowledge in their own dedicated source files [protocol].c etc. There's some "leakage" where this policy is violated, to be addressed at a later point in time.
2013-08-12urldata: clean up the use of the protocol specific structsDaniel Stenberg
1 - always allocate the struct in protocol->setup_connection. Some protocol handlers had to get this function added. 2 - always free at the end of a request. This is also an attempt to keep less memory in the handle after it is completed.

2013-08-08global dns cache: fix memory leakDaniel Stenberg
The take down of the global dns cache didn't take CURLOPT_RESOLVE names into account.
2013-08-08global dns cache: didn't work [regression]Daniel Stenberg
CURLOPT_DNS_USE_GLOBAL_CACHE broke in commit c43127414d89ccb (been broken since the libcurl 7.29.0 release). While this option has been documented as deprecated for almost a decade and nobody even reported this bug, it should remain functional. Added test case 1512 to verify
2013-08-08FTP: renamed several local functionsDaniel Stenberg
The previous naming scheme ftp_state_post_XXXX() wasn't really helpful as it wasn't always immediately after 'xxxx' and it wasn't easy to understand what it does based on such a name. This new one is instead ftp_state_yyyy() where yyyy describes what it does or sends.
2013-08-06FTP: when EPSV gets a 229 but fails to connect, retry with PASVDaniel Stenberg
This is a regression as this logic used to work. It isn't clear when it broke, but I'm assuming in 7.28.0 when we went all-multi internally. This likely never worked with the multi interface. As the failed connection is detected once the multi state has reached DO_MORE, the Curl_do_more() function was now expanded somewhat so that the ftp_do_more() function can request to go "back" to the previous state when it makes another attempt - using PASV. Added test case 1233 to verify this fix. It has the little issue that it assumes no service is listening/accepting connections on port 1... Reported-by: byte_bucket in the #curl IRC channel
2013-08-05md5: remove use of CommonCrypto-to-OpenSSL macros for the benefit of LeopardNick Zitzmann
For some reason, OS X 10.5's GCC suddenly stopped working correctly with macros that change MD5_Init etc. in the code to CC_MD5_Init etc., so I worked around this by removing use of the macros and inserting static functions that just call CommonCrypto's implementations of the functions instead.
2013-08-05Simplify check for trusted certificates.Guenter Knauf
This changes the previous check for untrusted certs to a check for certs explicitely marked as trusted. The change is backward-compatible (tested with certdata.txt v1.80).
2013-08-04formadd: wrong pointer for file name when CURLFORM_BUFFERPTR usedDaniel Stenberg
The internal function that's used to detect known file extensions for the default Content-Type got the the wrong pointer passed in when CURLFORM_BUFFER + CURLFORM_BUFFERPTR were used. This had the effect that strlen() would be used which could lead to an out-of-bounds read (and thus segfault). In most cases it would only lead to it not finding or using the correct default content-type. It also showed that test 554 and test 587 were testing for the previous/wrong behavior and now they're updated as well. Bug: http://curl.haxx.se/bug/view.cgi?id=1262 Reported-by: Konstantin Isakov
2013-08-04Skip more untrusted certificates.Guenter Knauf
Christian Heimes brought to our attention that the certdata.txt format has recently changed [1], causing ca-bundle.crt created with mk-ca-bundle.[pl|vbs] to include untrusted certs. [1] http://lists.debian.org/debian-release/2012/11/msg00411.html

Not needed
2013-08-03multi: remove the one_easy struct fieldDaniel Stenberg
Since the merge of SessionHandle with Curl_one_easy, this indirection isn't used anymore.
2013-08-03multi: rename all Curl_one_easy to SessionHandleDaniel Stenberg
2013-08-03multi: remove the multi_pos struct fieldDaniel Stenberg
Since Curl_one_easy is really a SessionHandle now, this indirection doesn't exist anymore.
2013-08-03multi: remove easy_handle struct fieldDaniel Stenberg
It isn't needed anymore
2013-08-03multi: remove 'Curl_one_easy' struct, phase 1Daniel Stenberg
The motivation for having a separate struct that keep track of an easy handle when using the multi handle was removed when we switched to always using the multi interface internally. Now they were just two separate struct that was always allocated for each easy handle. This first step just moves the Curl_one_easy struct members into the SessionHandle struct and hides this somehow (== keeps the source code changes to a minimum) by defining Curl_one_easy to SessionHandle The biggest changes in this commit are: 1 - the linked list of easy handles had to be changed somewhat due to the new struct layout. This made the main linked list pointer get renamed to 'easyp' and there's also a new pointer to the last node, called easylp. It is no longer circular but ends with ->next pointing to NULL. New nodes are still added last. 2 - easy->state is now called easy->mstate to avoid name collision
2013-07-30darwinssl: added LFs to some strings passed into infof()Nick Zitzmann
(This doesn't need to appear in the release notes.) I noticed a few places where infof() was called, and there should've been an LF at the end of the string, but there wasn't.
2013-07-30darwinssl: fix build error in crypto authentication under Snow LeopardNick Zitzmann
It turns out Snow Leopard not only has SecItemCopyMatching() defined in a header not included by the omnibus header, but it won't work for our purposes, because searching for SecIdentityRef objects wasn't added to that API until Lion. So we now use the old SecKeychainSearch API instead if the user is building under, or running under, Snow Leopard. Bug: http://sourceforge.net/p/curl/bugs/1255/ Reported by: Edward Rudd
2013-07-30md5 & metalink: use better build macros on Apple operating systemsNick Zitzmann
Previously we used __MAC_10_X and __IPHONE_X to mark digest-generating code that was specific to OS X and iOS. Now we use __MAC_OS_X_VERSION_MAX_ALLOWED and __IPHONE_OS_VERSION_MAX_ALLOWED instead of those macros. Bug: http://sourceforge.net/p/curl/bugs/1255/ Reported by: Edward Rudd
2013-07-29curl_easy_pause: on unpause, trigger mulit-socket handlingDaniel Stenberg
When the multi-socket API is used, we need the handle to be checked again when it gets unpaused. Bug: http://curl.haxx.se/mail/lib-2013-07/0239.html Reported-by: Justin Karneges
2013-07-29curl_formadd: fix file upload on VMSJohn E. Malmberg
For the standard VMS text file formats, VMS needs to read the file to get the actual file size. For the standard VMS binary file formats, VMS needs a special format of fopen() call so that it stops reading at the logical end of file instead of at the end of the blocks allocated to the file. I structured the patch this way as I was not sure about changing the structures or parameters to the routines, but would prefer to only call the stat() function once and pass the information to where the fopen() call is made. Bug: https://sourceforge.net/p/curl/bugs/758/
2013-07-26formadd: CURLFORM_FILECONTENT wrongly rejected some option combosDaniel Stenberg
The code for CURLFORM_FILECONTENT had its check for duplicate options wrong so that it would reject CURLFORM_PTRNAME if used in combination with it (but not CURLFORM_COPYNAME)! The flags field used for this purpose cannot be interpreted that broadly. Bug: http://curl.haxx.se/mail/lib-2013-07/0258.html Reported-by: Byrial Jensen

Commit 6d30f8ebed34e7276 didn't work properly. First, it used the wrong array index, but this fix also: 1 - only does the copying if indeed there was any activity 2 - makes sure to properly translate between internal and external bitfields, which are not guaranteed to match Reported-by: Evgeny Turnaev
2013-07-19curl_easy_perform: gradually increase the delay timeDaniel Stenberg
Instead of going 50,100,150 etc millisecond delay time when nothing has been found to do or wait for, we now start lower and double each loop as in 4,8,16,32 etc. This lowers the minimum wait without sacrifizing the longer wait too much with unnecessary CPU cycles burnt.

2013-07-19ftp_do_more: consider DO_MORE complete when server connects backDaniel Stenberg
In the case of an active connection when ftp_do_more() detects that the server has connected back, it must make sure to mark it as complete so that the multi_runsingle() function will detect this and move on to the next state.

2013-07-18CURLOPT_XFERINFOFUNCTION: introducing a new progress callbackDaniel Stenberg
CURLOPT_XFERINFOFUNCTION is now the preferred progress callback function and CURLOPT_PROGRESSFUNCTION is considered deprecated. This new callback uses pure 'curl_off_t' arguments to pass on full resolution sizes. It otherwise retains the same characteristics: the same call rate, the same meanings for the arguments and the return code is used the same way. The progressfunc.c example is updated to show how to use the new callback for newer libcurls while supporting the older one if built with an older libcurl or even built with a newer libcurl while running with an older.
2013-07-18Reinstate "WIN32 MemoryTracking: track wcsdup() _wcsdup() and _tcsdup() usage".Yang Tse
This reverts commit 7ed25cc, reinstating commit 8ec2cb5. As of 18-jul-2013 we still do have code in libcurl that makes use of these memory functions. Commit 8ec2cb5 comment still applies and is yet valid. These memory functions are solely used in Windows builds, so all related code is protected with '#ifdef WIN32' preprocessor conditional compilation directives. Specifically, wcsdup() _wcsdup() are used when building a Windows target with UNICODE and USE_WINDOWS_SSPI preprocessor symbols defined. This is the case when building a Windows UNICODE target with Windows native SSL/TLS support enabled. Realizing that wcsdup() _wcsdup() are used is a bit tricky given that usage of these is hidden behind _tcsdup() which is MS way of dealing with code that must tolerate UNICODE and non-UNICODE compilation. Additionally, MS header files and those compatible from other compilers use this preprocessor conditional compilation directive in order to select at compilation time whether 'wide' or 'ansi' MS API functions are used. Without this code, Windows build targets with Windows native SSL/TLS support enabled and MemoryTracking support enabled misbehave in tracking memory usage, regardless of being a UNICODE enabled build or not.
