2015-06-17Kconfig: disable Media Controller for DVBMauro Carvalho Chehab1-0/+1
Since when we start discussions about the usage Media Controller for complex hardware, one thing become clear: the way it is, MC fails to map anything different than capture/output/m2m video-only streaming. The point is that MC has entities named as devnodes, but the only devnode used (before the DVB patches) is MEDIA_ENT_T_DEVNODE_V4L. Due to the way MC got implemented, however, this entity actually doesn't represent the devnode, but the hardware I/O engine that receives data via DMA. By coincidence, such DMA is associated with the V4L device node on webcam hardware, but this is not true even for other V4L2 devices. For example, on USB hardware, the DMA is done via the USB controller. The data passes though a in-kernel filter that strips off the URB headers. Other V4L2 devices like radio may not even have DMA. When it have, the DMA is done via ALSA, and not via the V4L devnode. In other words, MC is broken as a whole, but tagging it as BROKEN right now would do more harm than good. So, instead, let's mark, for now, the DVB part as broken and block all new changes to MC while we fix this mess, whith we hopefully will do for the next Kernel version.

2015-06-17mm: shmem_zero_setup skip security check and lockdep conflict with XFSHugh Dickins1-1/+7
It appears that, at some point last year, XFS made directory handling changes which bring it into lockdep conflict with shmem_zero_setup(): it is surprising that mmap() can clone an inode while holding mmap_sem, but that has been so for many years. Since those few lockdep traces that I've seen all implicated selinux, I'm hoping that we can use the __shmem_file_setup(,,,S_PRIVATE) which v3.13's commit c7277090927a ("security: shmem: implement kernel private shmem inodes") introduced to avoid LSM checks on kernel-internal inodes: the mmap("/dev/zero") cloned inode is indeed a kernel-internal detail. This also covers the !CONFIG_SHMEM use of ramfs to support /dev/zero (and MAP_SHARED|MAP_ANONYMOUS). I thought there were also drivers which cloned inode in mmap(), but if so, I cannot locate them now.

2015-06-16crypto: caam - fix RNG buffer cache alignmentSteve Cornelius1-1/+1
The hwrng output buffers (2) are cast inside of a a struct (caam_rng_ctx) allocated in one DMA-tagged region. While the kernel's heap allocator should place the overall struct on a cacheline aligned boundary, the 2 buffers contained within may not necessarily align. Consenquently, the ends of unaligned buffers may not fully flush, and if so, stale data will be left behind, resulting in small repeating patterns. This fix aligns the buffers inside the struct. Note that not all of the data inside caam_rng_ctx necessarily needs to be DMA-tagged, only the buffers themselves require this. However, a fix would incur the expense of error-handling bloat in the case of allocation failure.

2015-06-16crypto: caam - improve initalization for context state savesSteve Cornelius1-0/+2
Multiple function in asynchronous hashing use a saved-state block, a.k.a. struct caam_hash_state, which holds a stash of information between requests (init/update/final). Certain values in this state block are loaded for processing using an inline-if, and when this is done, the potential for uninitialized data can pose conflicts. Therefore, this patch improves initialization of state data to prevent false assignments using uninitialized data in the state block. This patch addresses the following traceback, originating in ahash_final_ctx(), although a problem like this could certainly exhibit other symptoms: kernel BUG at arch/arm/mm/dma-mapping.c:465!

lapic.timer_mode was not properly initialized after migration, which broke few useful things, like login, by making every sleep eternal. Fix this by calling apic_update_lvtt in kvm_apic_post_state_restore. There are other slowpaths that update lvtt, so this patch makes sure something similar doesn't happen again by calling apic_update_lvtt after every modification.

2015-06-15ALSA: hda - Fix audio crackles on Dell Latitude E7x40Takashi Iwai1-2/+15
We still got a report that the audio crackles and noises occur with the recent 4.1 kernels on Dell machines. These machines seem to need similar workarounds that have been applied to the recent Dell XPS 13 models. Since the codec of these machines (Dell Latitute E7240 and E7440) is different from XPS 13's one, we need a new fixup entry. Also, it was confirmed that the previous workaround to disable the widget power-save (commit [219f47e4f964: ALSA: hda - Disable widget power-saving for ALC292 & co]) is no longer needed after this fix. So, this patch includes the partial revert of the commit, too.

2015-06-15drm/i915: Always reset vma->ggtt_view.pages cache on unbindingChris Wilson1-1/+1
With the introduction of multiple views of an obj in the same vm, each vma was taught to cache its copy of the pages (so that different views could have different page arrangements). However, this missed decoupling those vma->ggtt_view.pages when the vma released its reference on the obj->pages. As we don't always free the vma, this leads to a possible scenario (e.g. execbuffer interrupted by the shrinker) where the vma points to a stale obj->pages, and explodes. Fixes regression from commit fe14d5f4e5468c5b80a24f1a64abcbe116143670 Author: Tvrtko Ursulin <tvrtko.ursulin@intel.com> Date: Wed Dec 10 17:27:58 2014 +0000 drm/i915: Infrastructure for supporting different GGTT views per object Tvrtko says, if someone else will be confused how this can happen, key is the reservation execbuffer path. That puts the VMA on the exec_list which prevents i915_vma_unbind and i915_gem_vma_destroy from fully destroying the VMA. So the VMA is left existing as an empty object in the list - unbound and disassociated with the backing store. Kind of a cached memory object. And then re-using it needs to clear the cached pages pointer which is fixed above.

2015-06-13IRQCHIP: mips-gic: Don't nest calls to do_IRQ()Rabin Vincent1-7/+14
The GIC chained handlers use do_IRQ() to call the subhandlers. This means that irq_enter() calls get nested, which leads to preempt count looking like we're in nested interrupts, which in turn leads to all system time being accounted as IRQ time in account_system_time(). Fix it by using generic_handle_irq(). Since these same functions are used in some systems (if cpu_has_veic) from a low-level vectored interrupt handler which does not go throught do_IRQ(), we need to do it conditionally.

2015-06-12sctp: allow authenticating DATA chunks that are bundled with COOKIE_ECHOMarcelo Ricardo Leitner1-1/+10
Currently, we can ask to authenticate DATA chunks and we can send DATA chunks on the same packet as COOKIE_ECHO, but if you try to combine both, the DATA chunk will be sent unauthenticated and peer won't accept it, leading to a communication failure. This happens because even though the data was queued after it was requested to authenticate DATA chunks, it was also queued before we could know that remote peer can handle authenticating, so sctp_auth_send_cid() returns false. The fix is whenever we set up an active key, re-check send queue for chunks that now should be authenticated. As a result, such packet will now contain COOKIE_ECHO + AUTH + DATA chunks, in that order.

Pull VT-d hardware workarounds from David Woodhouse: "This contains a workaround for hardware issues which I *thought* were never going to be seen on production hardware. I'm glad I checked that before the 4.1 release... Firstly, PASID support is so broken on existing chips that we're just going to declare the old capability bit 28 as 'reserved' and change the VT-d spec to move PASID support to another bit. So any existing hardware doesn't support SVM; it only sets that (now) meaningless bit 28. That patch *wasn't* imperative for 4.1 because we don't have PASID support yet. But *even* the extended context tables are broken — if you just enable the wider tables and use none of the new bits in them, which is precisely what 4.1 does, you find that translations don't work. It's this problem which I thought was caught in time to be fixed before production, but wasn't. To avoid triggering this issue, we now *only* enable the extended context tables on hardware which also advertises "we have PASID support and we actually tested it this time" with the new PASID feature bit. In addition, I've added an 'intel_iommu=ecs_off' command line parameter to allow us to disable it manually if we need to" * git://git.infradead.org/intel-iommu: iommu/vt-d: Only enable extended context tables if PASID is supported iommu/vt-d: Change PASID support to bit 40 of Extended Capability Register
