patch from Stefan Kratochwil <entwicklung@inovel.de> : canfestival-3-fm3_698.patch
Bug:
If an object dictionary entry was requested whose size exceeds
SDO_MAX_LENGTH_TRANSFERT, the memcpy() call at line 139 of objacces.c overwrites
the memory after *pDestData which causes stack corruption.
-> Bugfix:
The bug was corrected by size checking the requested data. An 'Out of
memory' error message will be generated if the requested data exceeds
SDO_MAX_LENGTH_TRANSFERT.

Additional changes:
Added dynamic buffer allocation for the SDO transfer. This feature can be used
if SDO_DYNAMIC_BUFFER_ALLOCATION is defined in config.h. The size of the
dynamically allocated buffer is controlled with
SDO_DYNAMIC_BUFFER_ALLOCATION_SIZE.
-> Note:
This change removes the detection of OD_LENGTH_DATA_INVALID errors!

patch from Christian Taedcke <hacking@taedcke.com> : fix-wrong-resetSDOline-for-sdo-timeout.patch
FIXED: - The sdo line must not be closed at the end of SDOTimeoutAlarm() if the same sdo line is closed and reopened for a new transfer inside the callback. (Patch from Jaroslav Fojtik)

CHANGE: SDO block mode added, without CRC support
WARNING : API change in client functions

timers_unix.c : remove sigint and sigterm catch
sdo : Allow multiple servers
The sdo transfer struct is not anymore referenced by server's node id but by
client or server number in the OD. Node id is not relevant in SDO transfert.

fixed bug with cross wmingw build

Removed unneccessary overhead introduced with the last fix.

Fixed incorrect struct access in sendPDO() and inserted a missing variable in sendOnePDOEvent(). These errors occured at compile-time when configuring the project with './configure --debug=PDO' or './configure --debug=WAR'.

Fix some side effects of EDS import, while editing afterward

FIXED: - changed make targets from "%o: %c" to "%.o: %.c" (Patch from irc <oleg_osov>)
find . -name 'Make*' | xargs perl -w -i.bak -p -e "s/\%o: \%c/%.o: %.c/g"

FIX: - if a sdo transfer timeout occurres, reset the sdo line even if the callback function does not.

FIXED: - Sdo lines with the internal state SDO_ABORTED_ITERNAL are now closed.

CHANGED: - canSend message parameter is now a const pointer
ADDED : - IXXAT specific can bus watchdog to restart the VCI2 driver if a bus off, data ovverrun or remote queue overrun is detected. The can adapter cannot recover on its own.
* * *
CHANGED: - IXXAT::m_watchdogTimerId from DWORD to UINT_PTR to fix compiler warning

FIXED: - compiler warning from printf format string

FIXED: - TimerInit() was missing

FIXED: - OK and NOT OK was wrong in canSend()

FIXED: - bug while normal sdo transfer initialization (setting the byte count)

FIXED: - Renamed macro for peak win32 driver, patch from mailinglist (post from Christian Boepple, 2010-09-08 14:38)

CHANGED: - function sendOnePDOevent (CO_Data* d, UNS32 pdoNum) into sendOnePDOevent (CO_Data* d, UNS8 pdoNum)
- added explicit casts to remove compiler warnings

CHANGED: - added explicit cast to remove compiler warning

CHANGED: - canReceive and canSend return now 1 on error and 0 on success

CHANGED: - added explicit cast to remove compiler warning

FIXED: - added CALLBACK to can callback function prototypes

FIXED: - added missing endif
* * *
FIXED: - moved #include <linux/delay.h> into the ifdef __KERNEL__ block

CHANGED: - async access queue has now blocking read

ADDED: - pause() for win32
* * *
CHANGED: - moved pause implementation to main.cpp
- default driver to ixxat, baudrate to 125K and slaveid to 0x40
* * *
FIXED: - append "K" to baudrate
- added TimerInit()

CHANGED: - moved wxwidget header
ADDED: - getopt include for win32
FIXED: - TimerInit must be done for win32, too
* * *
CHANGED: - getopt signature (temp change)
* * *
CHANGED: - moved getopt and windows include

ADDED: - LeaveMutex and EnterMutex to exported symbols

CHANGED: - if variable starts with a digit, add a "_" at the beginning
* * *
FIXED: - if callback array name starts with a digit, prepend "_"

CHANGED: - option to integrate a can driver statically (hack)
FIXED: - missing () in log message
* * *
CHANGED: - adapted UnLoadCanDriver() for the macro NOT_USE_DYNAMIC_LOADING

CHANGED: - enabled console debugging for Visual Studio 2003 and below (without __VA_ARGS__).
