2005-11-09[PATCH] sched: disable preempt in idle tasksNick Piggin2-1/+5
Run idle threads with preempt disabled. Also corrected a bugs in arm26's cpu_idle (make it actually call schedule()). How did it ever work before? Might fix the CPU hotplugging hang which Nigel Cunningham noted. We think the bug hits if the idle thread is preempted after checking need_resched() and before going to sleep, then the CPU offlined. After calling stop_machine_run, the CPU eventually returns from preemption and into the idle thread and goes to sleep. The CPU will continue executing previous idle and have no chance to call play_dead. By disabling preemption until we are ready to explicitly schedule, this bug is fixed and the idle threads generally become more robust.

2005-11-09[PATCH] remove ioctl32_handler_tChristoph Hellwig1-3/+1
Some architectures define and use this type in their compat_ioctl code, but all of them can easily use the identical ioctl_trans_handler_t type that is defined in common code.

2005-11-07[PATCH] consolidate sys_ptrace()Christoph Hellwig1-50/+5
The sys_ptrace boilerplate code (everything outside the big switch statement for the arch-specific requests) is shared by most architectures. This patch moves it to kernel/ptrace.c and leaves the arch-specific code as arch_ptrace. Some architectures have a too different ptrace so we have to exclude them. They continue to keep their implementations. For sh64 I had to add a sh64_ptrace wrapper because it does some initialization on the first call. For um I removed an ifdefed SUBARCH_PTRACE_SPECIAL block, but SUBARCH_PTRACE_SPECIAL isn't defined anywhere in the tree.

2005-10-30[PATCH] Don't uselessly export task_struct to userspace in core dumpsEric W. Biederman1-11/+6
task_struct is an internal structure to the kernel with a lot of good information, that is probably interesting in core dumps. However there is no way for user space to know what format that information is in making it useless. I grepped the GDB 6.3 source code and NT_TASKSTRUCT while defined is not used anywhere else. So I would be surprised if anyone notices it is missing. In addition exporting kernel pointers to all the interesting kernel data structures sounds like the very definition of an information leak. I haven't a clue what someone with evil intentions could do with that information, but in any attack against the kernel it looks like this is the perfect tool for aiming that attack. So since NT_TASKSTRUCT is useless as currently defined and is potentially dangerous, let's just not export it. (akpm: Daniel Jacobowitz <[email protected]> "would be amazed" if anything was using NT_TASKSTRUCT). Signed-off-by: Eric W.

2005-10-29[PATCH] mm: mm_init set_mm_countersHugh Dickins1-1/+0
How is anon_rss initialized? In dup_mmap, and by mm_alloc's memset; but that's not so good if an mm_counter_t is a special type. And how is rss initialized? By set_mm_counter, all over the place. Come on, we just need to initialize them both at once by set_mm_counter in mm_init (which follows the memcpy when forking).
