2849 6018 d 15 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 6019 d 1 h svoboda /branches/tracing/kernel/generic/ Use debug_lock in thread struct for finer locking, to avoid problems with waitq_wakeup  
2842 6019 d 18 h svoboda /branches/tracing/kernel/generic/src/udebug/ Fix and document verify_thread()  
2841 6019 d 18 h svoboda /branches/tracing/kernel/generic/src/udebug/ Add verify_thread() to check that a thread is valid for debug ops  
2840 6019 d 18 h svoboda /branches/tracing/kernel/generic/src/ipc/ Fix: Clear kb_thread_at_hand when terminating kbox thread  
2839 6019 d 19 h svoboda /branches/tracing/kernel/generic/ Add thread_attach_by_id() and use it to do ipc_connect_kbox() with proper locking  
2838 6019 d 21 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 6020 d 1 h svoboda /branches/tracing/ Handle hangup message sent to kbox. Exit kbox thread when the last phone has been disconnected.  
2836 6020 d 2 h svoboda /branches/tracing/kernel/generic/src/ipc/ Fix: only create kbox thread if it doesn't exist yet  
2835 6020 d 3 h svoboda /branches/tracing/ Improve UDEBUG_M_END handling, switch sctrace to async API  
2834 6020 d 14 h svoboda /branches/tracing/kernel/generic/src/udebug/ Handle UDEBUG_M_END call, fix check in udebug_syscall_event()  
2833 6020 d 15 h svoboda /branches/tracing/ Remove buffer size argument from ARGS_READ call.  
2832 6020 d 17 h svoboda /branches/tracing/ Add separate syscall tracing program (sctrace), displaying correct number of arguments and return value decoding  
2827 6024 d 1 h svoboda /branches/tracing/kernel/generic/ Verify that a thread/task is in appropriate state when handling debug calls  
2826 6024 d 3 h svoboda /branches/tracing/kernel/generic/ Move debug_go_call from task struct to thread struct  
2825 6024 d 3 h svoboda /branches/tracing/kernel/generic/ Introduce task debug-states (udebug_task_state_t)  
2824 6024 d 4 h svoboda /branches/tracing/kernel/generic/src/udebug/ Use intermediate buffers for handling REGS_READ, REGS_WRITE and THREADS_READ  
2823 6024 d 4 h svoboda /branches/tracing/kernel/generic/src/udebug/ Improve locking in udebug.c and udebug_ipc.c  
2819 6024 d 17 h svoboda /branches/tracing/kernel/generic/src/udebug/ Fix: crashed caused by missing return in switch statement  
2818 6024 d 17 h svoboda /branches/tracing/kernel/generic/ Add MEM_WRITE debug method for writing a task's memory  
2817 6024 d 18 h svoboda /branches/tracing/kernel/generic/ Add REGS_READ and REGS_WRITE debug methods to access userspace register state (no effect yet)  
2816 6024 d 20 h svoboda /branches/tracing/kernel/generic/src/udebug/ Use thread-struct pointer for identification within debug connection  
2815 6024 d 21 h svoboda /branches/tracing/kernel/generic/ Move kernelbox debug message handling to udebug/udebug_ipc.c  
2813 6025 d 0 h svoboda /branches/tracing/ Move debug call preprocessing from ipc/sysipc.c to udebug/udebug_ipc.c  
2812 6025 d 1 h svoboda /branches/tracing/ Group debug IPC calls under a single method number, differentiate by ARG1  
2811 6025 d 1 h svoboda /branches/tracing/uspace/lib/libc/include/ipc/ Fix missing arguments to ipc_call_sync_slow() in ipc_call_sync_4_x macros  
2810 6025 d 2 h svoboda /branches/tracing/kernel/generic/src/ipc/ fix bug in debug_args_read() that caused it to only copy 6 bytes  
2809 6025 d 2 h svoboda /branches/tracing/ add call to read the debugged task's memory  
2808 6025 d 17 h svoboda /branches/tracing/ add kernel answerbox+thread to mediate access to task's memory  
2807 6026 d 4 h svoboda /branches/tracing/ initial support for debugging multithreaded tasks  
2806 6026 d 21 h svoboda /branches/tracing/uspace/app/tester/debug/ display syscall names in trace  
2805 6026 d 21 h svoboda /branches/tracing/ add ipc call to retrieve syscall arguments  
2804 6026 d 22 h svoboda /branches/tracing/kernel/generic/ allow for attaching to tasks with sleeping threads  
2803 6027 d 0 h svoboda /branches/tracing/kernel/generic/src/proc/ fix: initialize debug fields in task structure  
2801 6027 d 3 h svoboda /branches/tracing/ [tracing] initial debug interface support  
2800 6027 d 3 h svoboda /branches/tracing/kernel/generic/ [tracing] fix initialiation of answerbox->task in ipc_answerbox_init  
2799 6027 d 4 h svoboda /branches/tracing/ Revert all changes in tracing branch (sync to r2785 of trunk)  
2787 6035 d 20 h decky /branches/tracing/ add dynamic linking, debugging and tracing branch  
2785 6036 d 14 h jermar /trunk/uspace/app/tester/ Finish run_safe_tests() in app/tester (contributed by Tim Post).  
2784 6043 d 15 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.
