2851 6014 d 11 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 6014 d 11 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 6014 d 21 h svoboda /branches/tracing/kernel/generic/ Use debug_lock in thread struct for finer locking, to avoid problems with waitq_wakeup  
2842 6015 d 14 h svoboda /branches/tracing/kernel/generic/src/udebug/ Fix and document verify_thread()  
2841 6015 d 14 h svoboda /branches/tracing/kernel/generic/src/udebug/ Add verify_thread() to check that a thread is valid for debug ops  
2840 6015 d 14 h svoboda /branches/tracing/kernel/generic/src/ipc/ Fix: Clear kb_thread_at_hand when terminating kbox thread  
2839 6015 d 14 h svoboda /branches/tracing/kernel/generic/ Add thread_attach_by_id() and use it to do ipc_connect_kbox() with proper locking  
2838 6015 d 17 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 6015 d 21 h svoboda /branches/tracing/ Handle hangup message sent to kbox. Exit kbox thread when the last phone has been disconnected.  
2836 6015 d 22 h svoboda /branches/tracing/kernel/generic/src/ipc/ Fix: only create kbox thread if it doesn't exist yet  
2835 6015 d 23 h svoboda /branches/tracing/ Improve UDEBUG_M_END handling, switch sctrace to async API  
2834 6016 d 10 h svoboda /branches/tracing/kernel/generic/src/udebug/ Handle UDEBUG_M_END call, fix check in udebug_syscall_event()  
2833 6016 d 11 h svoboda /branches/tracing/ Remove buffer size argument from ARGS_READ call.  
2827 6019 d 21 h svoboda /branches/tracing/kernel/generic/ Verify that a thread/task is in appropriate state when handling debug calls  
2826 6019 d 22 h svoboda /branches/tracing/kernel/generic/ Move debug_go_call from task struct to thread struct  
2825 6019 d 23 h svoboda /branches/tracing/kernel/generic/ Introduce task debug-states (udebug_task_state_t)  
2824 6020 d 0 h svoboda /branches/tracing/kernel/generic/src/udebug/ Use intermediate buffers for handling REGS_READ, REGS_WRITE and THREADS_READ  
2823 6020 d 0 h svoboda /branches/tracing/kernel/generic/src/udebug/ Improve locking in udebug.c and udebug_ipc.c  
2819 6020 d 13 h svoboda /branches/tracing/kernel/generic/src/udebug/ Fix: crashed caused by missing return in switch statement  
2818 6020 d 13 h svoboda /branches/tracing/kernel/generic/ Add MEM_WRITE debug method for writing a task's memory  
2817 6020 d 14 h svoboda /branches/tracing/kernel/generic/ Add REGS_READ and REGS_WRITE debug methods to access userspace register state (no effect yet)  
2816 6020 d 16 h svoboda /branches/tracing/kernel/generic/src/udebug/ Use thread-struct pointer for identification within debug connection  
2815 6020 d 17 h svoboda /branches/tracing/kernel/generic/ Move kernelbox debug message handling to udebug/udebug_ipc.c  
2813 6020 d 20 h svoboda /branches/tracing/ Move debug call preprocessing from ipc/sysipc.c to udebug/udebug_ipc.c  
2812 6020 d 21 h svoboda /branches/tracing/ Group debug IPC calls under a single method number, differentiate by ARG1  
2810 6020 d 22 h svoboda /branches/tracing/kernel/generic/src/ipc/ fix bug in debug_args_read() that caused it to only copy 6 bytes  
2809 6020 d 22 h svoboda /branches/tracing/ add call to read the debugged task's memory  
2808 6021 d 13 h svoboda /branches/tracing/ add kernel answerbox+thread to mediate access to task's memory  
2807 6022 d 0 h svoboda /branches/tracing/ initial support for debugging multithreaded tasks  
2805 6022 d 17 h svoboda /branches/tracing/ add ipc call to retrieve syscall arguments  
2804 6022 d 18 h svoboda /branches/tracing/kernel/generic/ allow for attaching to tasks with sleeping threads  
2803 6022 d 20 h svoboda /branches/tracing/kernel/generic/src/proc/ fix: initialize debug fields in task structure  
2801 6022 d 23 h svoboda /branches/tracing/ [tracing] initial debug interface support  
2800 6022 d 23 h svoboda /branches/tracing/kernel/generic/ [tracing] fix initialiation of answerbox->task in ipc_answerbox_init  
2799 6023 d 0 h svoboda /branches/tracing/ Revert all changes in tracing branch (sync to r2785 of trunk)  
2787 6031 d 16 h decky /branches/tracing/ add dynamic linking, debugging and tracing branch  
2784 6039 d 11 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 6039 d 12 h jermar /trunk/kernel/arch/amd64/src/cpu/ Fix cstyle.  
2781 6043 d 20 h cejka /trunk/ Unified context saving/restoring macros in ppc32.  
2780 6043 d 20 h cejka /trunk/ Fixed broken context_offset.h symlinks for mips32eb and ia32xen.
