2018-08-22net: hns: fix skb->truesize underestimationHuazhong Tan1-1/+1
skb->truesize is not meant to be tracking amount of used bytes in a skb, but amount of reserved/consumed bytes in memory. For instance, if we use a single byte in last page fragment, we have to account the full size of the fragment. So skb_add_rx_frag needs to calculate the length of the entire buffer into turesize.

2018-08-22include/linux/compiler*.h: make compiler-*.h mutually exclusiveNick Desaulniers2-6/+1
Commit cafa0010cd51 ("Raise the minimum required gcc version to 4.6") recently exposed a brittle part of the build for supporting non-gcc compilers. Both Clang and ICC define __GNUC__, __GNUC_MINOR__, and __GNUC_PATCHLEVEL__ for quick compatibility with code bases that haven't added compiler specific checks for __clang__ or __INTEL_COMPILER. This is brittle, as they happened to get compatibility by posing as a certain version of GCC. This broke when upgrading the minimal version of GCC required to build the kernel, to a version above what ICC and Clang claim to be. Rather than always including compiler-gcc.h then undefining or redefining macros in compiler-intel.h or compiler-clang.h, let's separate out the compiler specific macro definitions into mutually exclusive headers, do more proper compiler detection, and keep shared definitions in compiler_types.h.

git://git.infradead.org/linux-platform-drivers-x86 Pull x86 platform driver updates from Andy Shevchenko: - The driver for Silead touchscreen configurations has been renamed from silead_dmi to touchscreen_dmi since it starts supporting other touchscreens which require some DMI quirks It also gets expanded to cover cases for Chuwi Vi10, ONDA V891W, Connect Tablet 9, Onda V820w, and Cube KNote i1101 tablets. - Another bunch of changes is related to Mellanox platform code to allow user space to communicate with Mellanox for system control and monitoring purposes. The driver notifies user on hotplug device signal receiving. - ASUS WMI drivers recognize lid flip action on UX360, and correctly toggles airplane mode LED. In addition the keyboard backlight toggle gets support. - ThinkPad ACPI driver enables support for calculator key (on at least P52). It also has been fixed to support three characters model designators, which are used for modern laptops. Earlier the battery, marked as BAT1, on ThinkPad laptops has not been configured properly, which is fixed. On the opposite the multi-battery configurations now probed correctly. - Dell SMBIOS driver starts working on some Dell servers which do not support token interface. The regression with backlight detection has also been fixed. In order to support dock mode on some laptops, Intel virtual button driver has been fixed. The last but not least is the fix to Intel HID driver due to changes in Dell systems that prevented to use power button. * tag 'platform-drivers-x86-v4.19-1' of git://git.infradead.org/linux-platform-drivers-x86: (47 commits) platform/x86: acer-wmi: Silence "unsupported" message a bit platform/x86: intel_punit_ipc: fix build errors platform/x86: ideapad: Add Y520-15IKBM and Y720-15IKBM to no_hw_rfkill platform/x86: asus-nb-wmi: Add keymap entry for lid flip action on UX360 platform/x86: acer-wmi: refactor function has_cap platform/x86: thinkpad_acpi: Fix multi-battery bug platform/x86: thinkpad_acpi: extend battery quirk coverage platform/x86: touchscreen_dmi: Add info for the Cube KNote i1101 tablet platform/x86: mlx-platform: Fix copy-paste error in mlxplat_init() platform/x86: mlx-platform: Remove unused define platform/x86: mlx-platform: Change mlxreg-io configuration for MSN274x systems Documentation/ABI: Add new attribute for mlxreg-io sysfs interfaces platform/x86: mlx-platform: Allow mlxreg-io driver activation for more systems platform/x86: mlx-platform: Add ASIC hotplug device configuration platform/mellanox: mlxreg-hotplug: Add hotplug hwmon uevent notification platform/mellanox: mlxreg-hotplug: Improve mechanism of ASIC health discovery platform/x86: mlx-platform: Add mlxreg-fan platform driver activation platform/x86: dell-laptop: Fix backlight detection platform/x86: toshiba_acpi: Fix defined but not used build warnings platform/x86: thinkpad_acpi: Support battery quirk ...

2018-08-22drivers/block/zram/zram_drv.c: fix bug storing backing_devPeter Kalauskas1-1/+6
The call to strlcpy in backing_dev_store is incorrect. It should take the size of the destination buffer instead of the size of the source buffer. Additionally, ignore the newline character (\n) when reading the new file_name buffer. This makes it possible to set the backing_dev as follows: echo /dev/sdX > /sys/block/zram0/backing_dev The reason it worked before was the fact that strlcpy() copies 'len - 1' bytes, which is strlen(buf) - 1 in our case, so it accidentally didn't copy the trailing new line symbol. Which also means that "echo -n /dev/sdX" most likely was broken.

2018-08-22mm, oom: distinguish blockable mode for mmu notifiersMichal Hocko9-39/+143
There are several blockable mmu notifiers which might sleep in mmu_notifier_invalidate_range_start and that is a problem for the oom_reaper because it needs to guarantee a forward progress so it cannot depend on any sleepable locks. Currently we simply back off and mark an oom victim with blockable mmu notifiers as done after a short sleep. That can result in selecting a new oom victim prematurely because the previous one still hasn't torn its memory down yet. We can do much better though. Even if mmu notifiers use sleepable locks there is no reason to automatically assume those locks are held. Moreover majority of notifiers only care about a portion of the address space and there is absolutely zero reason to fail when we are unmapping an unrelated range. Many notifiers do really block and wait for HW which is harder to handle and we have to bail out though. This patch handles the low hanging fruit. __mmu_notifier_invalidate_range_start gets a blockable flag and callbacks are not allowed to sleep if the flag is set to false. This is achieved by using trylock instead of the sleepable lock for most callbacks and continue as long as we do not block down the call chain. I think we can improve that even further because there is a common pattern to do a range lookup first and then do something about that. The first part can be done without a sleeping lock in most cases AFAICS. The oom_reaper end then simply retries if there is at least one notifier which couldn't make any progress in !blockable mode. A retry loop is already implemented to wait for the mmap_sem and this is basically the same thing. The simplest way for driver developers to test this code path is to wrap userspace code which uses these notifiers into a memcg and set the hard limit to hit the oom. This can be done e.g. after the test faults in all the mmu notifier managed memory and set the hard limit to something really small. Then we are looking for a proper process tear down.

2018-08-22ata: libahci_platform: add reset control supportKunihiko Hayashi2-5/+27
Add support to get and control a list of resets for the device as optional and shared. These resets must be kept de-asserted until the device is enabled. This is specified as shared because some SoCs like UniPhier series have common reset controls with all ahci controller instances. However, according to Thierry's view, https://www.spinics.net/lists/linux-ide/msg55357.html some hardware-specific drivers already use their own resets, and the common reset make a path to occur double controls of resets. The ahci_platform_get_resources() can get and control the reset only when the second argument includes AHCI_PLATFORM_GET_RESETS bit.

2018-08-22ata: add an extra argument to ahci_platform_get_resources()Kunihiko Hayashi15-15/+17
Add an extra argument to ahci_platform_get_resources(), that is for the bitmap representing the resource to get in this function. Currently there is no resources to be defined, so all the callers set '0' to the argument.

2018-08-21iscsi target: fix session creation failure handlingMike Christie1-14/+21
The problem is that iscsi_login_zero_tsih_s1 sets conn->sess early in iscsi_login_set_conn_values. If the function fails later like when we alloc the idr it does kfree(sess) and leaves the conn->sess pointer set. iscsi_login_zero_tsih_s1 then returns -Exyz and we then call iscsi_target_login_sess_out and access the freed memory. This patch has iscsi_login_zero_tsih_s1 either completely setup the session or completely tear it down, so later in iscsi_target_login_sess_out we can just check for it being set to the connection.
