[PATCH] arm64: ptrace: fix empty registers set in prstatus of aarch32 process core

by Victor Kamensky

Currently core file of aarch32 process prstatus note has empty registers set. As result aarch32 core files create by V8 kernel are not very useful. It happens because compat_gpr_get and compat_gpr_set functions can copy registers values to/from either kbuf or ubuf. ELF core file collection function fill_thread_core_info calls compat_gpr_get with kbuf set and ubuf set to 0. But current compat_gpr_get and compat_gpr_set function handle copy to/from only ubuf case. Fix is to handle kbuf and ubuf as two separate cases in similar way as other functions like user_regset_copyout, user_regset_copyin do.

[PATCH v6 0/2] context tracker support for arm64

by Larry Bassel

Implement and enable context tracking for arm64 (which is a prerequisite for FULL_NOHZ support). This patchset builds upon earlier work by Kevin Hilman and is based on Will Deacon's tree. Changes v5 to v6: * Don't save far_el1 in x26 in el0_dbg path (not needed) * TIF_NOHZ processes go through the slow path (so no register save/restore is needed in ct_user_enter) Changes v4 to v5: * Improvement to code restoring far_el1 (suggested by Christopher Covington) * Improvement to register save/restore in ct_user_enter Changes v3 to v4: * Rename parameter of ct_user_exit from save to restore * Rebased patch to Will Deacon's tree (branch remotes/origin/aarch64 of git://git.kernel.org/pub/scm/linux/kernel/git/will/linux.git) Changes v2 to v3: * Save/restore necessary registers in ct_user_enter and ct_user_exit * Annotate "error paths" out of el0_sync with ct_user_exit Changes v1 to v2: * Save far_el1 in x26 temporarily Larry Bassel (2): arm64: adjust el0_sync so that a function can be called arm64: enable context tracking arch/arm64/Kconfig | 1 + arch/arm64/include/asm/thread_info.h | 4 +++ arch/arm64/kernel/entry.S | 58 +++++++++++++++++++++++++++++++----- 3 files changed, 56 insertions(+), 7 deletions(-) -- 1.8.3.2

[PATCH] arm64: ptrace: fix empty registers set in prstatus of aarch32 process core

by Victor Kamensky

Hi Catalin, Will, I've run into situation when core of aarch32 (V7) process created by V8 kernel has empty registers set saved in prstatus notes. As result core file are broken. Below are details on the issues. Proposed patch follows this cover letter. Test Case For Problem --------------------- V8 kernel runs with v7 rootfs. Below output for BE system but LE has the same issue. hello test case compiled as v7 code.

[PATCH 3.11 068/138] hrtimer: Set expiry time before switch_hrtimer_base()

by Luis Henriques

3.11.10.11 -stable review patch. If anyone has any objections, please let me know. ------------------ From: Viresh Kumar <viresh.kumar(a)linaro.org> commit 84ea7fe37908254c3bd90910921f6e1045c1747a upstream. switch_hrtimer_base() calls hrtimer_check_target() which ensures that we do not migrate a timer to a remote cpu if the timer expires before the current programmed expiry time on that remote cpu. But __hrtimer_start_range_ns() calls switch_hrtimer_base() before the new expiry time is set. So the sanity check in hrtimer_check_target() is operating on stale or even uninitialized data. Update expiry time before calling switch_hrtimer_base().

[PATCH V3 0/8] Clockevents: Migrate to ->set_dev_mode()

by Viresh Kumar

Hi, This is my third attempt to migrate clockevent drivers to use set_dev_mode(). I have tried to fix all issues raised by Frederic/Kevin on V2. Please let me know if I missed something. Though patches 2-7 look big, it should be fairly easy to review them now, so do try that :) --------- A clockevent device should be stopped, or its events should be masked, if next event is expected at KTIME_MAX, i.e. no events are required for very long time. This would normally happen with NO_HZ (both NO_HZ_IDLE and NO_HZ_FULL) when tick-sched timer is removed and we don't have any more timers scheduled for long. If we don't STOP clockevent device, we are guaranteed to receive at least one spurious interrupt, as hrtimer_force_reprogram() isn't reprogramming the event device (on expires == KTIME_MAX). Depending on particular implementation of clockevent device, this can be a spurious interrupt at tick-rate.. (When driver is emulating ONESHOT over PERIODIC mode. This was observed on at-least one implementation: arm_arch_timer.c). A simple (yet hacky) solution to get this fixed could be: update hrtimer_force_reprogram() to always reprogram clockevent device and update clockevent drivers to STOP generating events (or delay it to max time), when 'expires' is set to KTIME_MAX. But the drawback here is that every clockevent driver has to be hacked for this particular case and its very easy for new ones to miss this. However, Thomas suggested to add an optional mode: ONESHOT_STOPPED (lkml.org/lkml/2014/5/9/508) to solve this problem. clockevents core would need to reconfigure mode later, when event is required again, for platforms that implement ONESHOT_STOPPED mode and so it must know which platforms implement it and which don't. This requires ->set_mode() callback to have capability to return 'success' or 'failure'. Currently its return type is 'void'. To change return type of set_mode(), Thomas suggested to implement another callback: ->set_dev_mode(), with return type 'int'. We can then convert clockevent drivers to use this interface instead of existing ->set_mode() and then finally remove ->set_mode()'s support. This patchset first adds another callback with return capability, set_dev_mode(), then it migrates all drivers one by one and finally removes earlier callback set_mode() when nobody is using it. NOTE: Following issue is still unresolved as this patchset isn't making it worse. But it should be fixed before addition of ONESHOT_STOPPED mode. Few clockevent drivers have disabled clock events as soon as we enter their ->set_dev_mode() callbacks and so they stay disabled for unsupported modes as well. All clockevent drivers are handling modes in ->set_dev_mode() with help of a 'switch' block. For the currently available modes none of them would ever get down to the 'default case' of switch block. And so we would never hit the BUG where we failed to change mode and still disabled clock events. But as soon as any new mode would be introduced in clockevents core, some of these might behave unexpectedly. Like, core may expect events to be enabled as call to ->set_dev_mode() returned failure and may not try enabling events again. V2->V3: - s/WARN_ON/WARN_ON_ONCE - improved logs - V2 had code belonging to problem mentioned in "NOTE" above, its dropped now and would be addressed separately.
