Commit c76f48eb5c08 ("block: take bd_mutex around delete_partitions in del_gendisk") adds disk->part0->bd_mutex in del_gendisk(), this way causes the following AB/BA deadlock between removing loop and opening loop: 1) loop_control_ioctl(LOOP_CTL_REMOVE) -> mutex_lock(&loop_ctl_mutex) -> del_gendisk -> mutex_lock(&disk->part0->bd_mutex) 2) blkdev_get_by_dev -> mutex_lock(&disk->part0->bd_mutex) -> lo_open -> mutex_lock(&loop_ctl_mutex) Add a new Lo_deleting state to remove the need for clearing ->private_data and thus holding loop_ctl_mutex in the ioctl LOOP_CTL_REMOVE path.

2021-06-11x86, lto: Pass -stack-alignment only on LLD < 13.0.0Tor Vic
Since LLVM commit 3787ee4, the '-stack-alignment' flag has been dropped [1], leading to the following error message when building a LTO kernel with Clang-13 and LLD-13: ld.lld: error: -plugin-opt=-: ld.lld: Unknown command line argument '-stack-alignment=8'. Try 'ld.lld --help' ld.lld: Did you mean '--stackrealign=8'? It also appears that the '-code-model' flag is not necessary anymore starting with LLVM-9 [2]. Drop '-code-model' and make '-stack-alignment' conditional on LLD < 13.0.0. These flags were necessary because these flags were not encoded in the IR properly, so the link would restart optimizations without them. Now there are properly encoded in the IR, and these flags exposing implementation details are no longer necessary.

2021-06-11usb: xhci: tegra: Enable ELPG for runtime/system PMJC Kuo
This commit implements the complete programming sequence for ELPG entry and exit. 1. At ELPG entry, invokes tegra_xusb_padctl_enable_phy_sleepwalk() and tegra_xusb_padctl_enable_phy_wake() to configure XUSB PADCTL sleepwalk and wake detection circuits to maintain USB lines level and respond to wake events (wake-on-connect, wake-on-disconnect, device-initiated-wake). 2. At ELPG exit, invokes tegra_xusb_padctl_disable_phy_sleepwalk() and tegra_xusb_padctl_disable_phy_wake() to disarm sleepwalk and wake detection circuits. At runtime suspend, XUSB host controller can enter ELPG to reduce power consumption. When XUSB PADCTL wake detection circuit detects a wake event, an interrupt will be raised. xhci-tegra driver then will invoke pm_runtime_resume() for xhci-tegra. Runtime resume could also be triggered by protocol drivers, this is the host-initiated-wake event. At runtime resume, xhci-tegra driver brings XUSB host controller out of ELPG to handle the wake events. The same ELPG enter/exit procedure will be performed for system suspend/resume path so USB devices can remain connected across SC7.

2021-06-11usb: xhci: tegra: Unlink power domain devicesJC Kuo
This commit unlinks xhci-tegra platform device with SS/host power domain devices. Reasons for this change is - at ELPG entry, PHY sleepwalk and wake configuration need to be done before powering down SS/host partitions, and PHY need be powered off after powering down SS/host partitions. Sequence looks like roughly below: tegra_xusb_enter_elpg() -> xhci_suspend() -> enable PHY sleepwalk and wake if needed -> power down SS/host partitions -> power down PHY If SS/host power domains are linked to xhci-tegra platform device, we are not able to perform the sequence like above. This commit introduces: 1. tegra_xusb_unpowergate_partitions() to power up SS and host partitions together. If SS/host power domain devices are available, it invokes pm_runtime_get_sync() to request power driver to power up partitions; If power domain devices are not available, tegra_powergate_sequence_power_up() will be used to power up partitions. 2. tegra_xusb_powergate_partitions() to power down SS and host partitions together. If SS/host power domain devices are available, it invokes pm_runtime_put_sync() to request power driver to power down partitions; If power domain devices are not available, tegra_powergate_power_off() will be used to power down partitions.

2021-06-11perf session: Correct buffer copying when peeking eventsLeo Yan
When peeking an event, it has a short path and a long path. The short path uses the session pointer "one_mmap_addr" to directly fetch the event; and the long path needs to read out the event header and the following event data from file and fill into the buffer pointer passed through the argument "buf". The issue is in the long path that it copies the event header and event data into the same destination address which pointer "buf", this means the event header is overwritten. We are just lucky to run into the short path in most cases, so we don't hit the issue in the long path. This patch adds the offset "hdr_sz" to the pointer "buf" when copying the event data, so that it can reserve the event header which can be used properly by its caller.

2021-06-11objtool: Only rewrite unconditional retpoline thunk callsPeter Zijlstra
It turns out that the compilers generate conditional branches to the retpoline thunks like: 5d5: 0f 85 00 00 00 00 jne 5db <cpuidle_reflect+0x22> 5d7: R_X86_64_PLT32 __x86_indirect_thunk_r11-0x4 while the rewrite can only handle JMP/CALL to the thunks. The result is the alternative wrecking the code. Make sure to skip writing the alternatives for conditional branches.

When PAGE_SIZE is greater than 4kB, multiple stripes may share the same page. Thus, src_offs is added to async_xor_offs() with array of offsets. However, async_xor() passes NULL src_offs to async_xor_offs(). In such case, src_offs should not be updated. Add a check before the update.

2021-06-10io_uring: change registration/upd/rsrc tagging ABIPavel Begunkov
There are ABI moments about recently added rsrc registration/update and tagging that might become a nuisance in the future. First, IORING_REGISTER_RSRC[_UPD] hide different types of resources under it, so breaks fine control over them by restrictions. It works for now, but once those are wanted under restrictions it would require a rework. It was also inconvenient trying to fit a new resource not supporting all the features (e.g. dynamic update) into the interface, so better to return to IORING_REGISTER_* top level dispatching. Second, register/update were considered to accept a type of resource, however that's not a good idea because there might be several ways of registration of a single resource type, e.g. we may want to add non-contig buffers or anything more exquisite as dma mapped memory. So, remove IORING_RSRC_[FILE,BUFFER] out of the ABI, and place them internally for now to limit changes.

2021-06-10coredump: Limit what can interrupt coredumpsEric W. Biederman
Olivier Langlois has been struggling with coredumps being incompletely written in processes using io_uring. Olivier Langlois <olivier@trillion01.com> writes: > io_uring is a big user of task_work and any event that io_uring made a > task waiting for that occurs during the core dump generation will > generate a TIF_NOTIFY_SIGNAL. > > Here are the detailed steps of the problem: > 1. io_uring calls vfs_poll() to install a task to a file wait queue > with io_async_wake() as the wakeup function cb from io_arm_poll_handler() > 2. wakeup function ends up calling task_work_add() with TWA_SIGNAL > 3. task_work_add() sets the TIF_NOTIFY_SIGNAL bit by calling > set_notify_signal() The coredump code deliberately supports being interrupted by SIGKILL, and depends upon prepare_signal to filter out all other signals. Now that signal_pending includes wake ups for TIF_NOTIFY_SIGNAL this hack in dump_emitted by the coredump code no longer works. Make the coredump code more robust by explicitly testing for all of the wakeup conditions the coredump code supports. This prevents new wakeup conditions from breaking the coredump code, as well as fixing the current issue. The filesystem code that the coredump code uses already limits itself to only aborting on fatal_signal_pending. So it should not develop surprising wake-up reasons either. v2: Don't remove the now unnecessary code in prepare_signal.

2021-06-10usb: typec: ucsi: Clear PPM capability data in ucsi_init() error pathMayank Rana
If ucsi_init() fails for some reason (e.g. ucsi_register_port() fails or general communication failure to the PPM), particularly at any point after the GET_CAPABILITY command had been issued, this results in unwinding the initialization and returning an error. However the ucsi structure's ucsi_capability member retains its current value, including likely a non-zero num_connectors. And because ucsi_init() itself is done in a workqueue a UCSI interface driver will be unaware that it failed and may think the ucsi_register() call was completely successful. Later, if ucsi_unregister() is called, due to this stale ucsi->cap value it would try to access the items in the ucsi->connector array which might not be in a proper state or not even allocated at all and results in NULL or invalid pointer dereference. Fix this by clearing the ucsi->cap value to 0 during the error path of ucsi_init() in order to prevent a later ucsi_unregister() from entering the connector cleanup loop.

2021-06-10usb: gadget: fsl: Re-enable driver for ARM SoCsJoel Stanley
The commit a390bef7db1f ("usb: gadget: fsl_mxc_udc: Remove the driver") dropped the ARCH_MXC dependency from USB_FSL_USB2, leaving it depending solely on FSL_SOC. FSL_SOC is powerpc only; it was briefly available on ARM in 2014 but was removed by commit cfd074ad8600 ("ARM: imx: temporarily remove CONFIG_SOC_FSL from LS1021A"). Therefore the driver can no longer be enabled on ARM platforms. This appears to be a mistake as arm64's ARCH_LAYERSCAPE and arm32 SOC_LS1021A SoCs use this symbol. It's enabled in these defconfigs: arch/arm/configs/imx_v6_v7_defconfig:CONFIG_USB_FSL_USB2=y arch/arm/configs/multi_v7_defconfig:CONFIG_USB_FSL_USB2=y arch/powerpc/configs/mgcoge_defconfig:CONFIG_USB_FSL_USB2=y arch/powerpc/configs/mpc512x_defconfig:CONFIG_USB_FSL_USB2=y To fix, expand the dependencies so USB_FSL_USB2 can be enabled on the ARM platforms, and with COMPILE_TEST.
