[PATCH 4.14 00/91] 4.14.39-stable review

by Greg Kroah-Hartman

This is the start of the stable review cycle for the 4.14.39 release. There are 91 patches in this series, all will be posted as a response to this one. If anyone has any issues with these being applied, please let me know. Responses should be made by Wed May 2 18:39:37 UTC 2018. Anything received after that time might be too late. The whole patch series can be found in one patch at: https://www.kernel.org/pub/linux/kernel/v4.x/stable-review/patch-4.14.39-rc… or in the git tree and branch at: git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable-rc.git linux-4.14.y and the diffstat can be found below. thanks, greg k-h ------------- Pseudo-Shortlog of commits: Greg Kroah-Hartman <gregkh(a)linuxfoundation.org> Linux 4.14.39-rc1 Nicolas Dichtel <nicolas.dichtel(a)6wind.com> net: don't call update_pmtu unconditionally Michael Neuling <mikey(a)neuling.org> powerpc/eeh: Fix race with driver un/bind Marc Zyngier <marc.zyngier(a)arm.com> arm/arm64: KVM: Add PSCI version selection API Thomas Gleixner <tglx(a)linutronix.de> tick/sched: Do not mess with an enqueued hrtimer Borislav Petkov <bp(a)suse.de> x86/microcode: Do not exit early from __reload_late() Borislav Petkov <bp(a)suse.de> x86/microcode/intel: Save microcode patch unconditionally Yazen Ghannam <yazen.ghannam(a)amd.com> x86/smpboot: Don't use mwait_play_dead() on AMD systems Arnd Bergmann <arnd(a)arndb.de> x86/ipc: Fix x32 version of shmid64_ds and msqid64_ds Sergey Senozhatsky <sergey.senozhatsky(a)gmail.com> tools/lib/subcmd/pager.c: do not alias select() params Josh Poimboeuf <jpoimboe(a)redhat.com> objtool, perf: Fix GCC 8 -Wrestrict error Imre Deak <imre.deak(a)intel.com> drm/i915: Enable display WA#1183 from its correct spot Nicolai Hähnle <nicolai.haehnle(a)amd.com> drm/amdgpu: set COMPUTE_PGM_RSRC1 for SGPR/VGPR clearing shaders Nicholas Piggin <npiggin(a)gmail.com> rtc: opal: Fix OPAL RTC driver OPAL_BUSY loops Shilpasri G Bhat <shilpa.bhat(a)linux.vnet.ibm.com> cpufreq: powernv: Fix hardlockup due to synchronous smp_call in timer interrupt Daniel Kurtz <djkurtz(a)chromium.org> earlycon: Use a pointer table to fix __earlycon_table stride Anatolij Gustschin <agust(a)denx.de> fpga-manager: altera-ps-spi: preserve nCONFIG state Ilya Dryomov <idryomov(a)gmail.com> libceph: validate con->state at the top of try_write() Ilya Dryomov <idryomov(a)gmail.com> libceph: reschedule a tick in finish_hunting() Ilya Dryomov <idryomov(a)gmail.com> libceph: un-backoff on tick when we have a authenticated session Nicolin Chen <nicoleotsuka(a)gmail.com> ASoC: fsl_esai: Fix divisor calculation failure at lower ratio Stephan Mueller <smueller(a)chronox.de> crypto: drbg - set freed buffers to NULL Alistair Popple <alistair(a)popple.id.au> powerpc/powernv/npu: Do a PID GPU TLB flush when invalidating a large address range Balbir Singh <bsingharora(a)gmail.com> powerpc/mm: Flush cache on memory hot(un)plug Marc Zyngier <marc.zyngier(a)arm.com> KVM: arm/arm64: Close VMID generation race Thor Thayer <thor.thayer(a)linux.intel.com> ARM: socfpga_defconfig: Remove QSPI Sector 4K size force Geert Uytterhoeven <geert+renesas(a)glider.be> ARM: amba: Don't read past the end of sysfs "driver_override" buffer Geert Uytterhoeven <geert+renesas(a)glider.be> ARM: amba: Fix race condition with driver_override Geert Uytterhoeven <geert+renesas(a)glider.be> ARM: amba: Make driver_override output consistent with other buses Evan Wang <xswang(a)marvell.com> PCI: aardvark: Fix PCIe Max Read Request Size setting Victor Gu <xigu(a)marvell.com> PCI: aardvark: Use ISR1 instead of ISR0 interrupt in legacy irq mode Victor Gu <xigu(a)marvell.com> PCI: aardvark: Set PIO_ADDR_LS correctly in advk_pcie_rd_conf() Victor Gu <xigu(a)marvell.com> PCI: aardvark: Fix logic in advk_pcie_{rd,wr}_conf() Martijn Coenen <maco(a)android.com> ANDROID: binder: prevent transactions into own process.

FAILED: patch "[PATCH] tpm: self test failure should not cause suspend to fail" failed to apply to 4.4-stable tree

by gregkh＠linuxfoundation.org

The patch below does not apply to the 4.4-stable tree. If someone wants it applied there, or to any other stable or longterm tree, then please email the backport, including the original git commit id to <stable(a)vger.kernel.org>. thanks, greg k-h ------------------ original commit in Linus's tree ------------------ >From 0803d7befa15cab5717d667a97a66214d2a4c083 Mon Sep 17 00:00:00 2001 From: Chris Chiu <chiu(a)endlessm.com> Date: Tue, 20 Mar 2018 15:36:40 +0800 Subject: [PATCH] tpm: self test failure should not cause suspend to fail The Acer Acer Veriton X4110G has a TPM device detected as: tpm_tis 00:0b: 1.2 TPM (device-id 0xFE, rev-id 71) After the first S3 suspend, the following error appears during resume: tpm tpm0: A TPM error(38) occurred continue selftest Any following S3 suspend attempts will now fail with this error: tpm tpm0: Error (38) sending savestate before suspend PM: Device 00:0b failed to suspend: error 38 Error 38 is TPM_ERR_INVALID_POSTINIT which means the TPM is not in the correct state. This indicates that the platform BIOS is not sending the usual TPM_Startup command during S3 resume. >From this point onwards, all TPM commands will fail. The same issue was previously reported on Foxconn 6150BK8MC and Sony Vaio TX3. The platform behaviour seems broken here, but we should not break suspend/resume because of this. When the unexpected TPM state is encountered, set a flag to skip the affected TPM_SaveState command on later suspends.

[PATCH 0/3] v4.16 tpmdd backports

"tpm: add retry logic" caused merge conflicts so I picked couple of other fixes in order to get it apply cleanly.

If the machine has a large amount of memory (more than 64G), the size of a memory block can span multiple sections. By mistake, during hotremove we set only the first section to offline state. The bug was discovered because kernel selftest started to fail: https://lkml.kernel.org/r/20180423011247.GK5563@yexl-desktop After commit, "mm/memory_hotplug: optimize probe routine". But, the bug is older than this commit. In this optimization we also added a check for sections to be in a proper state during hotplug operation.

[PATCH] drm/vc4: Make sure vc4_bo_{inc, dec}_usecnt() calls are balanced

by Boris Brezillon

Commit b9f19259b84d ("drm/vc4: Add the DRM_IOCTL_VC4_GEM_MADVISE ioctl") introduced a mechanism to mark some BOs as purgeable to allow the driver to drop them under memory pressure. In order to implement this feature we had to add a mechanism to mark BOs as currently used by a piece of hardware which materialized through the ->usecnt counter. Plane code is supposed to increment usecnt when it attaches a BO to a plane and decrement it when it's done with this BO, which was done in the ->prepare_fb() and ->cleanup_fb() hooks. The problem is, async page flip logic does not go through the regular atomic update path, and ->prepare_fb() and ->cleanup_fb() are not called in this case. Fix that by manually calling vc4_bo_{inc,dec}_usecnt() in the async-page-flip path. Note that all this should go away as soon as we get generic async page flip support in the core, in the meantime, this fix should do the trick.

I believe all shipping BIOSes use "Google" as vendor, as it is what is specified in src/mainboard/google/Kconfig::MAINBOARD_VENDOR and our configs/build scripts do not override it.

Hmm, I just tried checking out tree from https://review.coreboot.org/coreboot.git and do not see this commit: dtor@dtor-ws:~/coreboot $ git show f56db262e46d3368ee4e5c9e19797853cab382cd fatal: bad object f56db262e46d3368ee4e5c9e19797853cab382cd dtor@dtor-ws:~/coreboot $ git log --oneline -1 HEAD 82d0f91420 (HEAD -> master, origin/master, origin/HEAD) soc/intel/apollolake: enable exception handling in every stage for glk Anyway, if you are overriding the shipping BIOS, then please adjust coreboot to use device-tree compatible bindings (via PRP0001 HID and _DSD properties - you can check out bindings for PENH device in Caroline to see how they can be used). This way we would not need to breed DMI quirks. Thanks. -- Dmitry
