b7285b4 kernel/sys.c: Clarify that UNAME26 does not generate unique versions anymore UNAME26 is a mechanism to report Linux's version as 2.6.x, for compatibility with old/broken software. Due to the way it is implemented, it would have to be updated after 5.0, to keep the resulting versions unique. Linus Torvalds argued: "Do we actually need this? I'd rather let it bitrot, and just let it return random versions. It will just start again at 2.4.60, won't it? Anybody who uses UNAME26 for a 5.x kernel might as well think it's still 4.x. The user space is so old that it can't possibly care about differences between 4.x and 5.x, can it? The only thing that matters is that it shows "2.4.<largeenough>", which it will do regardless" Signed-off-by: Jonathan Neuschäfer <j.neuschaefer@gmx.net> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> 13 January 2019, 22:38:03 UTC
dbc3c09 Merge tag 'armsoc-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC fixes from Olof Johansson: "A bigger batch than I anticipated this week, for two reasons: - Some fallout on Davinci from board file -> DTB conversion, that also includes a few longer-standing fixes (i.e. not recent regressions). - drivers/reset material that has been in linux-next for a while, but didn't get sent to us until now for a variety of reasons (maintainer out sick, holidays, etc). There's a functional dependency in there such that one platform (Altera's SoCFPGA) won't boot without one of the patches; instead of reverting the patch that got merged, I looked at this set and decided it was small enough that I'll pick it up anyway. If you disagree I can revisit with a smaller set. That being said, there's also a handful of the usual stuff: - Fix for a crash on Armada 7K/8K when the kernel touches PSCI-reserved memory - Fix for PCIe reset on Macchiatobin (Armada 8K development board, what this email is sent from in fact :) - Enable a few new-merged modules for Amlogic in arm64 defconfig - Error path fixes on Integrator - Build fix for Renesas and Qualcomm - Initialization fix for Renesas RZ/G2E .. plus a few more fixlets" * tag 'armsoc-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (28 commits) ARM: integrator: impd1: use struct_size() in devm_kzalloc() qcom-scm: Include <linux/err.h> header gpio: pl061: handle failed allocations ARM: dts: kirkwood: Fix polarity of GPIO fan lines arm64: dts: marvell: mcbin: fix PCIe reset signal arm64: dts: marvell: armada-ap806: reserve PSCI area ARM: dts: da850-lcdk: Correct the sound card name ARM: dts: da850-lcdk: Correct the audio codec regulators ARM: dts: da850-evm: Correct the sound card name ARM: dts: da850-evm: Correct the audio codec regulators ARM: davinci: omapl138-hawk: fix label names in GPIO lookup entries ARM: davinci: dm644x-evm: fix label names in GPIO lookup entries ARM: davinci: dm355-evm: fix label names in GPIO lookup entries ARM: davinci: da850-evm: fix label names in GPIO lookup entries ARM: davinci: da830-evm: fix label names in GPIO lookup entries arm64: defconfig: enable modules for amlogic s400 sound card reset: uniphier-glue: Add AHCI reset control support in glue layer dt-bindings: reset: uniphier: Add AHCI core reset description reset: uniphier-usb3: Rename to reset-uniphier-glue dt-bindings: reset: uniphier: Replace the expression of USB3 with generic peripherals ... 13 January 2019, 22:34:14 UTC

e170672 phy: fix build breakage: add PHY_MODE_SATA Commit 49e54187ae0b ("ata: libahci_platform: comply to PHY framework") uses the PHY_MODE_SATA, but that enum had not yet been added. This caused a build failure for me, with today's linux.git. Also, there is a potentially conflicting (mis-named) PHY_MODE_SATA, hiding in the Marvell Berlin SATA PHY driver. Fix the build by: 1) Renaming Marvell's defined value to a more scoped name, in order to avoid any potential conflicts: PHY_BERLIN_MODE_SATA. 2) Adding the missing enum, which was going to be added anyway as part of [1].

To safely support mapping the allocations to userspace major architectures like x86 and arm have always zeroed allocations from dma_alloc_coherent, but a couple other architectures were missing that zeroing either always or in corner cases. Then later we grew anothe dma_zalloc_coherent interface to explicitly request zeroing, but that just added __GFP_ZERO to the allocation flags, which for some allocators that didn't end up using the page allocator ended up being a no-op and still not zeroing the allocations. So for this merge window I fixed up all remaining architectures to zero the memory in dma_alloc_coherent, and made dma_zalloc_coherent a no-op wrapper around dma_alloc_coherent, which fixes all of the above issues. dma_zalloc_coherent is now pointless and can go away, and Luis helped me writing a cocchinelle script and patch series to kill it, which I think we should apply now just after -rc1 to finally settle these issue" * tag 'remove-dma_zalloc_coherent-5.0' of git://git.infradead.org/users/hch/dma-mapping: dma-mapping: remove dma_zalloc_coherent() cross-tree: phase out dma_zalloc_coherent() on headers cross-tree: phase out dma_zalloc_coherent() 12 January 2019, 18:52:40 UTC

2f558bc ata: ahci: mvebu: add Armada 3700 initialization needed for S2RAM A3700 comphy initialization is done in the firmware (TF-A). Looking at the SATA PHY initialization routine, there is a comment about "vendor specific" registers. Two registers are mentioned. They are not initialized there in the firmware because they are AHCI related, while the firmware at this location does only PHY configuration. The solution to avoid doing such initialization is relying on U-Boot. While this work at boot time, U-Boot is definitely not going to run during a resume after suspending to RAM. Two possible solutions were considered: * Fixing the firmware. * Fixing the kernel driver. The first solution would take ages to propagate, while the second solution is easy to implement as the driver as been a little bit reworked to prepare for such platform configuration. Hence, this patch adds an Armada 3700 configuration function to set these two registers both at boot time (in the probe) and after a suspend (in the resume path).

96dbcb4 ata: ahci: mvebu: do Armada 38x configuration only on relevant SoCs At the beginning, only Armada 38x SoCs where supported by the ahci_mvebu.c driver. Commit 15d3ce7b63bd ("ata: ahci_mvebu: add support for Armada 3700 variant") introduced Armada 3700 support. As opposed to Armada 38x SoCs, the 3700 variants do not have to configure mbus and the regret option. This patch took care of avoiding such configuration when not needed in the probe function, but failed to do the same in the resume path. While doing so looks harmless by experience, let's clean the driver logic and avoid doing this useless configuration with Armada 3700 SoCs. Because the logic is very similar between these two places, it has been decided to factorize this code and put it in a "Armada 38x configuration function". This function is part of a new (per-compatible) platform data structure, so that the addition of such configuration function for Armada 3700 will be eased.

49e5418 ata: libahci_platform: comply to PHY framework Current implementation of the libahci does not take into account the new PHY framework. Correct the situation by adding a call to phy_set_mode() before phy_power_on(). PHYs should also be handled at suspend/resume time. For this, call ahci_platform_enable/disable_phys() at suspend/resume_host() time. These calls are guarded by a HFLAG (AHCI_HFLAG_SUSPEND_PHYS) that the user of the libahci driver must set manually in hpriv->flags at probe time. This is to avoid breaking users that have not been tested with this change.

ee258d7 CIFS: Move credit processing to mid callbacks for SMB3 Currently we account for credits in the thread initiating a request and waiting for a response. The demultiplex thread receives the response, wakes up the thread and the latter collects credits from the response buffer and add them to the server structure on the client. This approach is not accurate, because it may race with reconnect events in the demultiplex thread which resets the number of credits. Fix this by moving credit processing to new mid callbacks that collect credits granted by the server from the response in the demultiplex thread.

If the didn't get a response (no response buffer available) assume 0 credits granted. The latter most probably happens together with session reconnect, so the client's credits are adjusted anyway.

21face6 ARM: integrator: impd1: use struct_size() in devm_kzalloc() One of the more common cases of allocation size calculations is finding the size of a structure that has a zero-sized array at the end, along with memory for some number of elements for that array. For example: struct foo { int stuff; void *entry[]; }; instance = devm_kzalloc(dev, sizeof(struct foo) + sizeof(void *) * count, GFP_KERNEL); Instead of leaving these open-coded and prone to type mistakes, we can now use the new struct_size() helper: instance = devm_kzalloc(dev, struct_size(instance, entry, count), GFP_KERNEL); This code was detected with the help of Coccinelle.

b89d82e arm64: kpti: Avoid rewriting early page tables when KASLR is enabled A side effect of commit c55191e96caa ("arm64: mm: apply r/o permissions of VM areas to its linear alias as well") is that the linear map is created with page granularity, which means that transitioning the early page table from global to non-global mappings when enabling kpti can take a significant amount of time during boot. Given that most CPU implementations do not require kpti, this mainly impacts KASLR builds where kpti is forcefully enabled. However, in these situations we know early on that non-global mappings are required and can avoid the use of global mappings from the beginning. The only gotcha is Cavium erratum #27456, which we must detect based on the MIDR value of the boot CPU.

1b3922a btrfs: Use real device structure to verify dev extent [BUG] Linux v5.0-rc1 will fail fstests/btrfs/163 with the following kernel message: BTRFS error (device dm-6): dev extent devid 1 physical offset 13631488 len 8388608 is beyond device boundary 0 BTRFS error (device dm-6): failed to verify dev extents against chunks: -117 BTRFS error (device dm-6): open_ctree failed [CAUSE] Commit cf90d884b347 ("btrfs: Introduce mount time chunk <-> dev extent mapping check") introduced strict check on dev extents. We use btrfs_find_device() with dev uuid and fs uuid set to NULL, and only dependent on @devid to find the real device. For seed devices, we call clone_fs_devices() in open_seed_devices() to allow us search seed devices directly. However clone_fs_devices() just populates devices with devid and dev uuid, without populating other essential members, like disk_total_bytes. This makes any device returned by btrfs_find_device(fs_info, devid, NULL, NULL) is just a dummy, with 0 disk_total_bytes, and any dev extents on the seed device will not pass the device boundary check. [FIX] This patch will try to verify the device returned by btrfs_find_device() and if it's a dummy then re-search in seed devices.

Using any of the assigned objects without checking is not safe.

ba42273 mm/mmu_notifier: mm/rmap.c: Fix a mmu_notifier range bug in try_to_unmap_one The conversion to use a structure for mmu_notifier_invalidate_range_*() unintentionally changed the usage in try_to_unmap_one() to init the 'struct mmu_notifier_range' with vma->vm_start instead of @address, i.e. it invalidates the wrong address range. Revert to the correct address range. Manifests as KVM use-after-free WARNINGs and subsequent "BUG: Bad page state in process X" errors when reclaiming from a KVM guest due to KVM removing the wrong pages from its own mappings.

85f5a4d rbd: don't return 0 on unmap if RBD_DEV_FLAG_REMOVING is set There is a window between when RBD_DEV_FLAG_REMOVING is set and when the device is removed from rbd_dev_list. During this window, we set "already" and return 0. Returning 0 from write(2) can confuse userspace tools because 0 indicates that nothing was written.
