[PATCH 1/9] dm-integrity: change the variable suspending from bool to int

by Mikulas Patocka

The early alpha processors can't write a byte or short atomically - they read 8 bytes, modify the byte or two bytes in registers and write back 8 bytes. The modification of the variable "suspending" may race with modification of the variable "failed". This patch changes suspending to an int.

netfilter: nf_flow_table: attach dst to skbs

by Jason A. Donenfeld

Some drivers, such as vxlan and wireguard, use the skb's dst in order to determine things like PMTU. They therefore loose functionality when flow offloading is enabled. So, we ensure the skb has it before xmit'ing it in the offloading path. Signed-off-by: Jason A.

[PATCH v2 1/2] pwm: lpss: platform: Save/restore the ctrl register over a suspend/resume

by Hans de Goede

On some devices the contents of the ctrl register get lost over a suspend/resume and the PWM comes back up disabled after the resume. This is seen on some Bay Trail devices with the PWM in ACPI enumerated mode, so it shows up as a platform device instead of a PCI device. If we still think it is enabled and then try to change the duty-cycle after this, we end up with a "PWM_SW_UPDATE was not cleared" error and the PWM is stuck in that state from then on. This commit adds suspend and resume pm callbacks to the pwm-lpss-platform code, which save/restore the ctrl register over a suspend/resume, fixing this. Note that: 1) There is no need to do this over a runtime suspend, since we only runtime suspend when disabled and then we properly set the enable bit and reprogram the timings when we re-enable the PWM. 2) This may be happening on more systems then we realize, but has been covered up sofar by a bug in the acpi-lpss.c code which was save/restoring the regular device registers instead of the lpss private registers due to lpss_device_desc.prv_offset not being set. This is fixed by a later patch in this series.

Problems building ppc images in v4.14.y and v4.16.y using gcc 7.3.0 / 8.1.0 from kernel.org

by Guenter Roeck

Hi Arnd, when using the ppc64 compiler from kernel.org, I see the following problems when trying to compile ppc:allnoconfig in v4.14.y or v4.16.y. gcc 7.3.0: Compilation of kernel.cpu.o hangs The problem goes away if I apply the following two patches (tested with 4.16.y) 17a2f1ced028 cpu/hotplug: Merge cpuhp_bp_states and cpuhp_ap_states fcb3029a8d89 cpu/hotplug: Fix unused function warning gcc 8.1.0: Compilation of kernel/cpu.o results in the following error powerpc64-linux-gcc: error: unrecognized command line option '-mno-spe'; did you mean '-fno-see'? powerpc64-linux-gcc: error: unrecognized command line option '-mspe=no'; did you mean '-misel=no'? This problem is also seen with mainline. With ppc:defconfig, kernel/cpu.o builds fine with both compiler versions. Have you seen similar problems ? Any idea what to do about it, other than sticking with older compilers ? Thanks, Guenter

[PATCH 1/2] btrfs: scrub: Don't use inode pages for device replace

by Qu Wenruo

[BUG] Btrfs can easily create compressed extent without checksum (even though it shouldn't), and if we then try to replace device containing such extent, the result device will contain all the uncompressed data instead of the compressed one. Test case already submitted to fstests: https://patchwork.kernel.org/patch/10442353/ [CAUSE] When handling compressed extent without checksum, device replace will goes into copy_nocow_pages() function. In that function, btrfs will get all inodes referring to this data extents and then use find_or_create_page() to get pages direct from that inode. The problem here is, pages directly from inode are always uncompressed. And for compressed data extent, they mismatch with on-disk data. Thus this leads to corrupted data extent written to replace device. [FIX] In this patch, we could just avoid the "optimization" branch, and let unified scrub_pages() to handle it. Although scrub_pages() won't bother reusing page cache, thus it will be a little slower, but it does the correct csum checking (skipped in this case) and won't cause such data corruption cause by "optimization".

[PATCH V5] scsi: hpsa: disable device during shutdown

by Sinan Kaya

'Commit cc27b735ad3a ("PCI/portdrv: Turn off PCIe services during shutdown")' has been added to kernel to shutdown pending PCIe port service interrupts during reboot so that a newly started kexec kernel wouldn't observe pending interrupts. pcie_port_device_remove() is disabling the root port and switches by calling pci_disable_device() after all PCIe service drivers are shutdown. This has been found to cause crashes on HP DL360 Gen9 machines during reboot due to hpsa driver not clearing the bus master bit during the shutdown procedure by calling pci_disable_device(). Disable device as part of the shutdown sequence.

[PATCH v3 2/2] tpm: self test failure should not cause suspend to fail

by Jarkko Sakkinen

From: Chris Chiu <chiu(a)endlessm.com> commit 0803d7befa15cab5717d667a97a66214d2a4c083 upstream 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.

[git:media_tree/master] media: uvcvideo: Prevent setting unavailable flags

by Mauro Carvalho Chehab

This is an automatic generated email to let you know that the following patch were queued: Subject: media: uvcvideo: Prevent setting unavailable flags Author: Kieran Bingham <kieran.bingham(a)ideasonboard.com> Date: Wed Mar 21 11:43:08 2018 -0400 The addition of an extra operation to use the GET_INFO command overwrites all existing flags from the uvc_ctrls table. This includes setting all controls as supporting GET_MIN, GET_MAX, GET_RES, and GET_DEF regardless of whether they do or not. Move the initialisation of these control capabilities directly to the uvc_ctrl_fill_xu_info() call where they were originally located in that use case, and ensure that the new functionality in uvc_ctrl_get_flags() will only set flags based on their reported capability from the GET_INFO call.

[PATCH v4.9-stable] serial: pl011: add console matching function

by Ard Biesheuvel

From: Aleksey Makarov <aleksey.makarov(a)linaro.org> Commit 10879ae5f12e9cab3c4e8e9504c1aaa8a033bde7 upstream. This patch adds function pl011_console_match() that implements method match of struct console. It allows to match consoles against data specified in a string, for example taken from command line or compiled by ACPI SPCR table handler. This patch was merged to tty-next but then reverted because of conflict with commit 46e36683f433 ("serial: earlycon: Extend earlycon command line option to support 64-bit addresses") Now it is fixed.

Now that more systems are becoming available to people working in the kernel community, it turns out that v4.9 distro installers (e.g., Debian Stretch) won't work unless you pass a 'console=' parameter explicitly, which is annoying. Given that it was clearly the intent to include this code at the time, I hope it will be considered for backporting.

Patch 4b433924b275 ("scsi: sd_zbc: Fix potential memory leak") was added in 4.16 and 4.15 stable but did not make it to long term stable 4.14 (as far as I can tell).

Linux 4.9.106

I'm announcing the release of the 4.9.106 kernel.
