由 Paolo Bonzini 提交于
Before commit 0e60b079 (kvm: change memslot sorting rule from size to GFN, 2014-12-01), the memslots' sorting key was npages, meaning that a valid memslot couldn't have its sorting key equal to zero. On the other hand, a valid memslot can have base_gfn == 0, and invalid memslots are identified by base_gfn == npages == 0. Because of this, commit 0e60b079 broke the invariant that invalid memslots are at the end of the mslots array. When a memslot with base_gfn == 0 was created, any invalid memslot before it were left in place. This can be fixed by changing the insertion to use a ">=" comparison instead of "<=", but some care is needed to avoid breaking the case of deleting a memslot; see the comment in update_memslots.

The output memory operand and the input register operand both need to be reloaded using a register in class R1_REGS when generating 64-bit code.

This change is necessary to support HW which provides a total of more than 15 stream DMA engines which with legacy implementation causes an overflow on SDxCTL.STRM field (and the whole SDxCTL register) and as a result usage of Reserved value 0 in the SDxCTL.STRM field which confuses HDA controller.

A regression was caused by commit 780a7654: audit: Make testing for a valid loginuid explicit. (which in turn attempted to fix a regression caused by e1760bd5) When audit_krule_to_data() fills in the rules to get a listing, there was a missing clause to convert back from AUDIT_LOGINUID_SET to AUDIT_LOGINUID. This broke userspace by not returning the same information that was sent and expected. The rule: auditctl -a exit,never -F auid=-1 gives: auditctl -l LIST_RULES: exit,never f24=0 syscall=all when it should give: LIST_RULES: exit,never auid=-1 (0xffffffff) syscall=all Tag it so that it is reported the same way it was set.

由 Lorenzo Pieralisi 提交于
On arm64 the TTBR0_EL1 register is set to either the reserved TTBR0 page tables on boot or to the active_mm mappings belonging to user space processes, it must never be set to swapper_pg_dir page tables mappings. When a CPU is booted its active_mm is set to init_mm even though its TTBR0_EL1 points at the reserved TTBR0 page mappings. This implies that when __cpu_suspend is triggered the active_mm can point at init_mm even if the current TTBR0_EL1 register contains the reserved TTBR0_EL1 mappings. Therefore, the mm save and restore executed in __cpu_suspend might turn out to be erroneous in that, if the current->active_mm corresponds to init_mm, on resume from low power it ends up restoring in the TTBR0_EL1 the init_mm mappings that are global and can cause speculation of TLB entries which end up being propagated to user space. This patch fixes the issue by checking the active_mm pointer before restoring the TTBR0 mappings. If the current active_mm == &init_mm, the code sets the TTBR0_EL1 to the reserved TTBR0 mapping instead of switching back to the active_mm, which is the expected behaviour corresponding to the TTBR0_EL1 settings when __cpu_suspend was entered.

drm/tegra: Fixes for v3.19-rc1 This is a set of fixes for two regressions and one bug in the IOMMU mapping code. It turns out that all of these issues turn up primarily on Tegra30 hardware. The IOMMU mapping bug only manifests on buffers that aren't multiples of the page size. I happened to be testing HDMI with 1080p while writing the code and framebuffers for that happen to fit exactly within 2025 pages of 4 KiB each. One of the regressions is caused by the IOMMU code allocating pages from shmem which can have associated cache lines. If the pages aren't flushed then these cache lines may be flushed later on and cause framebuffer corruption. I'm not sure why I didn't see this before. Perhaps the board that I was using had enough RAM so that the pages shmem would hand out had a better chance of being unused. Or maybe I didn't look too closely. The fix for this is to fake up an SG table so that it can be passed to the DMA API. Ideally this would use drm_clflush_*(), but implementing that for ARM causes DRM to fail to build as a module since some of the low-level cache maintenance functions aren't exported. Hopefully we can get a suitable API exported on ARM for the next release. The second regression is caused by a mismatch between the hardware pipe number and the CRTC's DRM index. These were used inconsistently, which could cause one code location to call drm_vblank_get() with a different pipe than the corresponding drm_vblank_put(), thereby causing the reference count to become unbalanced. Alexandre also reported a possible race condition related to this, which this series also fixes. * tag 'drm/tegra/for-3.19-rc1-fixes' of git://people.freedesktop.org/~tagr/linux: drm/tegra: dc: Select root window for event dispatch drm/tegra: gem: Use the proper size for GEM objects drm/tegra: gem: Flush buffer objects upon allocation drm/tegra: dc: Fix a potential race on page-flip completion drm/tegra: dc: Consistently use the same pipe drm/irq: Add drm_crtc_vblank_count() drm/irq: Add drm_crtc_handle_vblank() drm/irq: Add drm_crtc_send_vblank_event()

There is a problem with the audit system when multiple audit records are created for the same path, each with a different path name type. The root cause of the problem is in __audit_inode() when an exact match (both the path name and path name type) is not found for a path name record; the existing code creates a new path name record, but it never sets the path name in this record, leaving it NULL. This patch corrects this problem by assigning the path name to these newly created records. There are many ways to reproduce this problem, but one of the easiest is the following (assuming auditd is running): # mkdir /root/tmp/test # touch /root/tmp/test/567 # auditctl -a always,exit -F dir=/root/tmp/test # touch /root/tmp/test/567 Afterwards, or while the commands above are running, check the audit log and pay special attention to the PATH records. A faulty kernel will display something like the following for the file creation: type=SYSCALL msg=audit(1416957442.025:93): arch=c000003e syscall=2 success=yes exit=3 ... comm="touch" exe="/usr/bin/touch" type=CWD msg=audit(1416957442.025:93): cwd="/root/tmp" type=PATH msg=audit(1416957442.025:93): item=0 name="test/" inode=401409 ... nametype=PARENT type=PATH msg=audit(1416957442.025:93): item=1 name=(null) inode=393804 ... nametype=NORMAL type=PATH msg=audit(1416957442.025:93): item=2 name=(null) inode=393804 ... nametype=NORMAL While a patched kernel will show the following: type=SYSCALL msg=audit(1416955786.566:89): arch=c000003e syscall=2 success=yes exit=3 ... comm="touch" exe="/usr/bin/touch" type=CWD msg=audit(1416955786.566:89): cwd="/root/tmp" type=PATH msg=audit(1416955786.566:89): item=0 name="test/" inode=401409 ... nametype=PARENT type=PATH msg=audit(1416955786.566:89): item=1 name="test/567" inode=393804 ... nametype=NORMAL This issue was brought up by a number of people, but special credit should go to hujianyang@huawei.com for reporting the problem along with an explanation of the problem and a patch.

If the data structure is larger than the machine word size memcpy is used and a warning is emitted. The next patches fix up several in-tree users of ACCESS_ONCE on non-scalar types. This does not yet contain a patch that forces ACCESS_ONCE to work only on scalar types. This is targetted for the next merge window as Linux next already contains new offenders regarding ACCESS_ONCE vs. non-scalar types" * tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/borntraeger/linux: s390/kvm: REPLACE barrier fixup with READ_ONCE arm/spinlock: Replace ACCESS_ONCE with READ_ONCE arm64/spinlock: Replace ACCESS_ONCE READ_ONCE mips/gup: Replace ACCESS_ONCE with READ_ONCE x86/gup: Replace ACCESS_ONCE with READ_ONCE x86/spinlock: Replace ACCESS_ONCE with READ_ONCE mm: replace ACCESS_ONCE with READ_ONCE or barriers kernel: Provide READ_ONCE and ASSIGN_ONCE

Pull clk framework updates from Mike Turquette: "This is much later than usual due to several last minute bugs that had to be addressed. As usual the majority of changes are new drivers and modifications to existing drivers. The core recieved many fixes along with the groundwork for several large changes coming in the future which will better parition clock providers from clock consumers" * tag 'clk-for-linus-3.19' of git://git.linaro.org/people/mike.turquette/linux: (86 commits) clk: samsung: Fix Exynos 5420 pinctrl setup and clock disable failure due to domain being gated ARM: OMAP3: clock: fix boot breakage in legacy mode ARM: OMAP2+: clock: fix DPLL code to use new determine rate APIs clk: Really fix deadlock with mmap_sem clk: mmp: fix sparse non static symbol warning clk: Change clk_ops->determine_rate to return a clk_hw as the best parent clk: change clk_debugfs_add_file to take a struct clk_hw clk: Don't expose __clk_get_accuracy clk: Don't try to use a struct clk* after it could have been freed clk: Remove unused function __clk_get_prepare_count clk: samsung: Fix double add of syscore ops after driver rebind clk: samsung: exynos4: set parent of sclk_hdmiphy to hdmi clk: samsung: exynos4415: Fix build with PM_SLEEP disabled clk: samsung: remove unnecessary inclusion of header files from clk.h clk: samsung: remove unnecessary CONFIG_OF from clk.c clk: samsung: Spelling s/bwtween/between/ clk: rockchip: Add support for the mmc clock phases using the framework clk: rockchip: add bindings for the mmc clocks clk: rockchip: rk3288 export i2s0_clkout for use in DT clk: rockchip: use clock ID for DMC (memory controller) on rk3288 ...
