2854 5928 d 12 h svoboda /branches/tracing/ Fix condition for generating debug events. Properly initialize threads created during debugging session  
2851 5928 d 23 h svoboda /branches/tracing/kernel/generic/src/udebug/ Fix locking order in udebug_rp_end (to the somewhat unintuitive threads_lock => t->debug_lock => t->lock  
2849 5928 d 23 h svoboda /branches/tracing/kernel/generic/src/udebug/ Move code for verifying and locking down a thread for a debugging op to _thread_op_begin()/_thread_op_end(). Rewritten to prevent case of mistaken task identity  
2848 5929 d 9 h svoboda /branches/tracing/kernel/generic/ Use debug_lock in thread struct for finer locking, to avoid problems with waitq_wakeup  
2842 5930 d 2 h svoboda /branches/tracing/kernel/generic/src/udebug/ Fix and document verify_thread()  
2841 5930 d 2 h svoboda /branches/tracing/kernel/generic/src/udebug/ Add verify_thread() to check that a thread is valid for debug ops  
2840 5930 d 3 h svoboda /branches/tracing/kernel/generic/src/ipc/ Fix: Clear kb_thread_at_hand when terminating kbox thread  
2839 5930 d 3 h svoboda /branches/tracing/kernel/generic/ Add thread_attach_by_id() and use it to do ipc_connect_kbox() with proper locking  
2838 5930 d 5 h svoboda /branches/tracing/ Respond to pending GO messages with UDEBUG_EVENT_FINISHED on terminating the debugging session. Set retval for DEBUG_END answer.  
2837 5930 d 9 h svoboda /branches/tracing/ Handle hangup message sent to kbox. Exit kbox thread when the last phone has been disconnected.  
2836 5930 d 11 h svoboda /branches/tracing/kernel/generic/src/ipc/ Fix: only create kbox thread if it doesn't exist yet  
2835 5930 d 11 h svoboda /branches/tracing/ Improve UDEBUG_M_END handling, switch sctrace to async API  
2834 5930 d 22 h svoboda /branches/tracing/kernel/generic/src/udebug/ Handle UDEBUG_M_END call, fix check in udebug_syscall_event()  
2833 5930 d 23 h svoboda /branches/tracing/ Remove buffer size argument from ARGS_READ call.  
2827 5934 d 9 h svoboda /branches/tracing/kernel/generic/ Verify that a thread/task is in appropriate state when handling debug calls  
2826 5934 d 11 h svoboda /branches/tracing/kernel/generic/ Move debug_go_call from task struct to thread struct  
2825 5934 d 11 h svoboda /branches/tracing/kernel/generic/ Introduce task debug-states (udebug_task_state_t)  
2824 5934 d 12 h svoboda /branches/tracing/kernel/generic/src/udebug/ Use intermediate buffers for handling REGS_READ, REGS_WRITE and THREADS_READ  
2823 5934 d 13 h svoboda /branches/tracing/kernel/generic/src/udebug/ Improve locking in udebug.c and udebug_ipc.c  
2819 5935 d 1 h svoboda /branches/tracing/kernel/generic/src/udebug/ Fix: crashed caused by missing return in switch statement  
2818 5935 d 2 h svoboda /branches/tracing/kernel/generic/ Add MEM_WRITE debug method for writing a task's memory  
2817 5935 d 2 h svoboda /branches/tracing/kernel/generic/ Add REGS_READ and REGS_WRITE debug methods to access userspace register state (no effect yet)  
2816 5935 d 5 h svoboda /branches/tracing/kernel/generic/src/udebug/ Use thread-struct pointer for identification within debug connection  
2815 5935 d 5 h svoboda /branches/tracing/kernel/generic/ Move kernelbox debug message handling to udebug/udebug_ipc.c  
2813 5935 d 8 h svoboda /branches/tracing/ Move debug call preprocessing from ipc/sysipc.c to udebug/udebug_ipc.c  
2812 5935 d 9 h svoboda /branches/tracing/ Group debug IPC calls under a single method number, differentiate by ARG1  
2810 5935 d 11 h svoboda /branches/tracing/kernel/generic/src/ipc/ fix bug in debug_args_read() that caused it to only copy 6 bytes  
2809 5935 d 11 h svoboda /branches/tracing/ add call to read the debugged task's memory  
2808 5936 d 1 h svoboda /branches/tracing/ add kernel answerbox+thread to mediate access to task's memory

2805 5937 d 5 h svoboda /branches/tracing/ add ipc call to retrieve syscall arguments  
2804 5937 d 7 h svoboda /branches/tracing/kernel/generic/ allow for attaching to tasks with sleeping threads  
2803 5937 d 8 h svoboda /branches/tracing/kernel/generic/src/proc/ fix: initialize debug fields in task structure  
2801 5937 d 11 h svoboda /branches/tracing/ [tracing] initial debug interface support  
2800 5937 d 12 h svoboda /branches/tracing/kernel/generic/ [tracing] fix initialiation of answerbox->task in ipc_answerbox_init  
2799 5937 d 12 h svoboda /branches/tracing/ Revert all changes in tracing branch (sync to r2785 of trunk)  
2787 5946 d 5 h decky /branches/tracing/ add dynamic linking, debugging and tracing branch  
2784 5954 d 0 h jermar /trunk/kernel/arch/ Fortify ia32 and amd64 kernels against mallicious uspace applications that set
DF prior to entering the kernel. For AMD64 syscalls, we don't use the CLD
instruction, but make use of the SFMASK MSR instead. Simics works fine with
it, but QEMU seems to have a problem.		  
2783 5954 d 0 h jermar /trunk/kernel/arch/amd64/src/cpu/ Fix cstyle.  
2781 5958 d 8 h cejka /trunk/ Unified context saving/restoring macros in ppc32.
