59b33f1 Helge Deller 01 October 2013, 19:54:46 UTC parisc: fix interruption handler to respect pagefault_disable() Running an "echo t > /proc/sysrq-trigger" crashes the parisc kernel. The problem is, that in print_worker_info() we try to read the workqueue info via the probe_kernel_read() functions which use pagefault_disable() to avoid crashes like this: probe_kernel_read(&pwq, &worker->current_pwq, sizeof(pwq)); probe_kernel_read(&wq, &pwq->wq, sizeof(wq)); probe_kernel_read(name, wq->name, sizeof(name) - 1); The problem here is, that the first probe_kernel_read(&pwq) might return zero in pwq and as such the following probe_kernel_reads() try to access contents of the page zero which is read protected and generate a kernel segfault. With this patch we fix the interruption handler to call parisc_terminate() directly only if pagefault_disable() was not called (in which case preempt_count()==0). Otherwise we hand over to the pagefault handler which will try to look up the faulting address in the fixup tables.

5b24282 Vineet Gupta 10 October 2013, 14:03:57 UTC ARC: Ignore ptrace SETREGSET request for synthetic register "stop_pc" ARCompact TRAP_S insn used for breakpoints, commits before exception is taken (updating architectural PC). So ptregs->ret contains next-PC and not the breakpoint PC itself. This is different from other restartable exceptions such as TLB Miss where ptregs->ret has exact faulting PC. gdb needs to know exact-PC hence ARC ptrace GETREGSET provides for @stop_pc which returns ptregs->ret vs. EFA depending on the situation. However, writing stop_pc (SETREGSET request), which updates ptregs->ret doesn't makes sense stop_pc doesn't always correspond to that reg as described above. This was not an issue so far since user_regs->ret / user_regs->stop_pc had same value and both writing to ptregs->ret was OK, needless, but NOT broken, hence not observed. With gdb "jump", they diverge, and user_regs->ret updating ptregs is overwritten immediately with stop_pc, which this patch fixes.

Adding drm/i915 into the vga arbiter chain means that X (in a piece of well-meant paranoia) will do a get/put on the vga decoding around _every_ accel call down into the ddx. Which results in some nice performance disasters [1]. This really breaks userspace, by disabling DRI for everyone, and stops OpenGL from working, this isn't limited to just the i915 but both the integrated and discrete GPUs on multi-gpu systems, in other words this causes untold worlds of pain, Ville tried to come up with a Great Hack to fiddle the required VGA I/O ops behind everyone's back using stop_machine, but that didn't really work out [2]. Given that we're fairly late in the -rc stage for such games let's just revert this all. One thing we might want to keep is to delay the disabling of the vga decoding until the fbdev emulation and the fbcon screen is set up. If we kill vga mem decoding beforehand fbcon can end up with a white square in the top-left corner it tried to save from the vga memory for a seamless transition. And we have bug reports on older platforms which seem to match these symptoms. But again that's something to play around with in -next.

7bf811a Josef Bacik 08 October 2013, 02:11:09 UTC Btrfs: limit delalloc pages outside of find_delalloc_range Liu fixed part of this problem and unfortunately I steered him in slightly the wrong direction and so didn't completely fix the problem. The problem is we limit the size of the delalloc range we are looking for to max bytes and then we try to lock that range. If we fail to lock the pages in that range we will shrink the max bytes to a single page and re loop. However if our first page is inside of the delalloc range then we will end up limiting the end of the range to a period before our first page. This is illustrated below [0 -------- delalloc range --------- 256mb] [page] So find_delalloc_range will return with delalloc_start as 0 and end as 128mb, and then we will notice that delalloc_start < *start and adjust it up, but not adjust delalloc_end up, so things go sideways. To fix this we need to not limit the max bytes in find_delalloc_range, but in find_lock_delalloc_range and that way we don't end up with this confusion.

40fde70 Bharat Bhushan 07 August 2013, 10:03:46 UTC kvm: ppc: booke: check range page invalidation progress on page setup When the MM code is invalidating a range of pages, it calls the KVM kvm_mmu_notifier_invalidate_range_start() notifier function, which calls kvm_unmap_hva_range(), which arranges to flush all the TLBs for guest pages. However, the Linux PTEs for the range being flushed are still valid at that point. We are not supposed to establish any new references to pages in the range until the ...range_end() notifier gets called. The PPC-specific KVM code doesn't get any explicit notification of that; instead, we are supposed to use mmu_notifier_retry() to test whether we are or have been inside a range flush notifier pair while we have been referencing a page. This patch calls the mmu_notifier_retry() while mapping the guest page to ensure we are not referencing a page when in range invalidation. This call is inside a region locked with kvm->mmu_lock, which is the same lock that is called by the KVM MMU notifier functions, thus ensuring that no new notification can proceed while we are in the locked region.

d0d538b Gleb Natapov 09 October 2013, 16:13:19 UTC KVM: nVMX: fix shadow on EPT 72f857950f6f19 broke shadow on EPT. This patch reverts it and fixes PAE on nEPT (which reverted commit fixed) in other way. Shadow on EPT is now broken because while L1 builds shadow page table for L2 (which is PAE while L2 is in real mode) it never loads L2's GUEST_PDPTR[0-3]. They do not need to be loaded because without nested virtualization HW does this during guest entry if EPT is disabled, but in our case L0 emulates L2's vmentry while EPT is enables, so we cannot rely on vmcs12->guest_pdptr[0-3] to contain up-to-date values and need to re-read PDPTEs from L2 memory. This is what kvm_set_cr3() is doing, but by clearing cache bits during L2 vmentry we drop values that kvm_set_cr3() read from memory. So why the same code does not work for PAE on nEPT? kvm_set_cr3() reads pdptes into vcpu->arch.walk_mmu->pdptrs[]. walk_mmu points to vcpu->arch.nested_mmu while nested guest is running, but ept_load_pdptrs() uses vcpu->arch.mmu which contain incorrect values. Fix that by using walk_mmu in ept_(load|save)_pdptrs.

25f2bd7 Henrik Rydberg 02 October 2013, 17:15:03 UTC hwmon: (applesmc) Always read until end of data The crash reported and investigated in commit 5f4513 turned out to be caused by a change to the read interface on newer (2012) SMCs. Tests by Chris show that simply reading the data valid line is enough for the problem to go away. Additional tests show that the newer SMCs no longer wait for the number of requested bytes, but start sending data right away. Apparently the number of bytes to read is no longer specified as before, but instead found out by reading until end of data. Failure to read until end of data confuses the state machine, which eventually causes the crash. As a remedy, assuming bit0 is the read valid line, make sure there is nothing more to read before leaving the read function. Tested to resolve the original problem, and runtested on MBA3,1, MBP4,1, MBP8,2, MBP10,1, MBP10,2. The patch seems to have no effect on machines before 2012.

39edac7 Anssi Hannula 07 October 2013, 16:24:52 UTC ALSA: hda - hdmi: Fix channel map switch not taking effect Currently hdmi_setup_audio_infoframe() reprograms the HDA channel mapping only when the infoframe is not up-to-date or the non-PCM flag has changed. However, when just the channel map has been changed, the infoframe may still be up-to-date and non-PCM flag may not have changed, so the new channel map is not actually programmed into the HDA codec. Notably, this failing case is also always triggered when the device is already in a prepared state and a new channel map is configured while changing only the channel positions (for example, plain "speaker-test -c2 -m FR,FL"). Fix that by always programming the channel map in hdmi_setup_audio_infoframe(). Tested on Intel HDMI.

If an interrupt happens at that point, we will not properly detect the re-entrancy and clobber the original return context on the irq stack. This fixes it. The side effect is to prevent all nesting from softirq stack to irq stack even in the "safe" case but it's simpler that way and matches what x86_64 does.

f50f9aa David Herrmann 02 October 2013, 11:47:28 UTC HID: wiimote: fix FF deadlock The input core has an internal spinlock that is acquired during event injection via input_event() and friends but also held during FF callbacks. That means, there is no way to share a lock between event-injection and FF handling. Unfortunately, this is what is required for wiimote state tracking and what we do with state.lock and input->lock. This deadlock can be triggered when using continuous data reporting and FF on a wiimote device at the same time. I takes me at least 30m of stress-testing to trigger it but users reported considerably shorter times (http://bpaste.net/show/132504/) when using some gaming-console emulators. The real problem is that we have two copies of internal state, one in the wiimote objects and the other in the input device. As the input-lock is not supposed to be accessed from outside of input-core, we have no other chance than offloading FF handling into a worker. This actually works pretty nice and also allows to implictly merge fast rumble changes into a single request. Due to the 3-layered workers (rumble+queue+l2cap) this might reduce FF responsiveness. Initial tests were fine so lets fix the race first and if it turns out to be too slow we can always handle FF out-of-band and skip the queue-worker.
