* arm/syscalls: Optimize address limit checkThomas Garnier2017-09-172-0/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Disable the generic address limit check in favor of an architecture specific optimized implementation. The generic implementation using pending work flags did not work well with ARM and alignment faults. The address limit is checked on each syscall return path to user-mode path as well as the irq user-mode return function. If the address limit was changed, a function is called to report data corruption (stopping the kernel or process based on configuration). The address limit check has to be done before any pending work because they can reset the address limit and the process is killed using a SIGKILL signal. For example the lkdtm address limit check does not work because the signal to kill the process will reset the user-mode address limit.

* Revert "arm/syscalls: Check address limit on user-mode return"Thomas Garnier2017-09-174-23/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This reverts commit 73ac5d6a2b6ac3ae8d1e1818f3e9946f97489bc9. The work pending loop can call set_fs after addr_limit_user_check removed the _TIF_FSCHECK flag. This may happen at anytime based on how ARM handles alignment exceptions. It leads to an infinite loop condition. After discussion, it has been agreed that the generic approach is not tailored to the ARM architecture and any fix might not be complete. This patch will be replaced by an architecture specific implementation. The work flag approach will be kept for other architectures.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This new clock driver set allows to have a fractional divided clock that would generate a precise clock particularly suitable for audio applications. The main audio pll clock has two children clocks: one that is connected to the PMC, the other that can directly drive a pad. As these two routes have different enable bits and different dividers and divider formulas, they are handled by two different drivers. Each of them could modify the rate of the main audio pll parent. The main audio pll clock can output 620MHz to 700MHz.

One can imagine building a similar watchdog for arbitrary driver threads using save_stack_trace_tsk() and print_stack_trace(). However, this is not viable for dynamically loaded driver modules on ARM platforms because save_stack_trace_tsk() is not exported for those architectures. Export save_stack_trace_tsk() for the ARM architecture to align with x86 and support various debugging use cases such as arbitrary driver thread watchdog timers.

The intent is that we'll return to the faulting userspace instruction, delivering the signal on the way. However, if we take a fatal signal during fixing up a uaccess, this results in a return to the faulting kernel instruction, which will be instantly retried, resulting in the same fault being taken forever. As the task never reaches userspace, the signal is not delivered, and the task is left unkillable. While the task is stuck in this state, it can inhibit the forward progress of the system. To avoid this, we must ensure that when a fatal signal is pending, we apply any necessary fixup for a faulting kernel instruction. Thus we will return to an error path, and it is up to that code to make forward progress towards delivering the fatal signal.
