3478 5760 d 8 h decky /branches/arm/ new arm branch  
3476 5762 d 1 h jermar /trunk/kernel/generic/src/ipc/ Add comments documenting our treatment of the task's active call counter.  
3449 5768 d 23 h jermar /trunk/kernel/generic/src/ipc/ Fix task active call accounting for IPC_M_HUNGUP calls.  
3445 5769 d 23 h jermar /trunk/kernel/ Rename ipc/ipc_kbox.c to ipc/kbox.c.  
3441 5770 d 6 h svoboda /trunk/kernel/generic/src/ Use LOG() instead of printf() for debug messages.  
3438 5770 d 7 h svoboda /trunk/ Merge syscall tracer (trace) and relevant part of udebug interface from tracing to trunk.  
3395 5778 d 0 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 5778 d 22 h jermar /trunk/kernel/generic/src/ipc/ cstyle for ipc.c  
3370 5790 d 22 h jermar /trunk/kernel/generic/ Synchronous IPC must be interruptible.  
3363 5794 d 1 h jermar /trunk/kernel/generic/src/ipc/ Demasquerade the caller phone during ipc_answer_n() rather than in
ipc_wait_for_call().		  
3362 5794 d 1 h jermar /trunk/kernel/generic/ Fix processing of answers to forwarded masqueraded calls.  
3332 5802 d 6 h jermar /trunk/kernel/generic/src/ipc/ Fix types when processing IPC_M_DATA_WRITE arguments.  
3186 5856 d 1 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 5857 d 3 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 5873 d 12 h svoboda /trunk/kernel/ Declare arguments for memstr.h operations as pointers instead of uintptr_t.  
3090 5876 d 4 h decky /trunk/kernel/generic/src/ipc/ revert coding style change  
3054 5876 d 5 h decky /trunk/kernel/generic/src/ipc/ proper printf formatting  
3020 5881 d 23 h jermar /trunk/kernel/generic/ Turn phone->lock into mutex.  
2934 5895 d 1 h jermar /trunk/ Do not attempt to malloc() zero bytes of memory during VFS_READ at end of file.  
2802 5935 d 8 h jermar /trunk/kernel/generic/ Fix initialization of answerbox->task in ipc_answerbox_init.
