3438 5768 d 15 h svoboda /trunk/ Merge syscall tracer (trace) and relevant part of udebug interface from tracing to trunk.  
3395 5776 d 8 h jermar /trunk/kernel/generic/ Kernel's ipc_data_t and uspace's ipc_call_t must be in sync.

This commit fixes a problem introduced in revision 3362, when
ipc_data_t was enlarged by the caller_phone member. This resulted
in sys_ipc_wait_for_call() passing larger structure to uspace
than requested, leading to a random damage of userspace memory.		  
3394 5777 d 6 h jermar /trunk/kernel/generic/src/ipc/ cstyle for ipc.c  
3370 5789 d 6 h jermar /trunk/kernel/generic/ Synchronous IPC must be interruptible.  
3363 5792 d 9 h jermar /trunk/kernel/generic/src/ipc/ Demasquerade the caller phone during ipc_answer_n() rather than in
ipc_wait_for_call().		  
3362 5792 d 9 h jermar /trunk/kernel/generic/ Fix processing of answers to forwarded masqueraded calls.  
3332 5800 d 14 h jermar /trunk/kernel/generic/src/ipc/ Fix types when processing IPC_M_DATA_WRITE arguments.  
3186 5854 d 9 h jermar /trunk/kernel/ Support for active mutexes. Active mutexes implement busy waiting, pretty much
in the same way as spinlocks, but can be passed to condition variables, which is
the motivation for this enhancement.		  
3184 5855 d 11 h jermar /trunk/kernel/generic/src/ipc/ Fix a scary two-year old bug: do not attempt to initialize a call structure if
its allocation failed.		  
3104 5871 d 20 h svoboda /trunk/kernel/ Declare arguments for memstr.h operations as pointers instead of uintptr_t.  
3090 5874 d 12 h decky /trunk/kernel/generic/src/ipc/ revert coding style change  
3054 5874 d 13 h decky /trunk/kernel/generic/src/ipc/ proper printf formatting  
3020 5880 d 7 h jermar /trunk/kernel/generic/ Turn phone->lock into mutex.  
2934 5893 d 9 h jermar /trunk/ Do not attempt to malloc() zero bytes of memory during VFS_READ at end of file.  
2802 5933 d 16 h jermar /trunk/kernel/generic/ Fix initialization of answerbox->task in ipc_answerbox_init.
Contributed by Jiri Svoboda.		  
2745 5971 d 16 h decky /trunk/ code cleanup (mostly signed/unsigned)
allow extra compiler warnings		  
2677 6029 d 11 h jermar /trunk/ Rename IPC_M_AS_AREA_SEND to IPC_M_SHARE_OUT. Rename IPC_M_AS_AREA_RECV to
IPC_M_SHARE_IN. Provide user-friendly wrappers for these methods so that even
dummies can get it right. Some applications using simpler protocols still use
these methods directly.		  
2676 6029 d 17 h jermar /trunk/ Simplify the IPC_M_DATA_WRITE protocol. Do not pass the source address space
virtual address to the recipient. This feature was not used anyway. Now
IPC_M_DATA_WRITE and IPC_M_DATA_READ are feature-aligned.		  
2662 6037 d 6 h jermar /trunk/ Add support for IPC_M_DATA_READ calls.  
2661 6037 d 7 h jermar /trunk/kernel/generic/src/ipc/ Release the IPC_M_DATA_WRITE buffer even if the write is refused by the
recipient.
