git://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux into arm/fixes Qualcomm ARM64 DeviceTree fixes for 5.17 This starts off by fixing an issue introduced in a bug fix in the global clock controller, where the symbol clocks for UFS would end up picking the wrong parent clock which breaks UFS. It then makes sure that the reference clock for the USB blocks are enabled, even with booting without clk_ignore_unused. It corrects the apps SMMU interrupts defintion by adding a missing interrupt in the list. Lastly it disables the Qualcomm crypto hardware (for now) on the Lenovo Yoga C630, to prevent the cryptomanager tests during boot from crashing the device. * tag 'qcom-arm64-fixes-for-5.17' of git://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux: arm64: dts: qcom: c630: disable crypto due to serror arm64: dts: qcom: sm8450: fix apps_smmu interrupts arm64: dts: qcom: sm8450: enable GCC_USB3_0_CLKREF_EN for usb arm64: dts: qcom: sm8350: Correct UFS symbol clocks Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Arnd Bergmann <[email protected]>

2022-03-01efi: fix return value of __setup handlersRandy Dunlap2-2/+2
When "dump_apple_properties" is used on the kernel boot command line, it causes an Unknown parameter message and the string is added to init's argument strings: Unknown kernel command line parameters "dump_apple_properties BOOT_IMAGE=/boot/bzImage-517rc6 efivar_ssdt=newcpu_ssdt", will be passed to user space. Run /sbin/init as init process with arguments: /sbin/init dump_apple_properties with environment: HOME=/ TERM=linux BOOT_IMAGE=/boot/bzImage-517rc6 efivar_ssdt=newcpu_ssdt Similarly when "efivar_ssdt=somestring" is used, it is added to the Unknown parameter message and to init's environment strings, polluting them (see examples above). Change the return value of the __setup functions to 1 to indicate that the __setup options have been handled.

2022-03-01soc: mediatek: mt8192-mmsys: Fix dither to dsi0 path's input selAngeloGioacchino Del Regno1-1/+2
In commit d687e056a18f ("soc: mediatek: mmsys: Add mt8192 mmsys routing table"), the mmsys routing table for mt8192 was introduced but the input selector for DITHER->DSI0 has no value assigned to it. This means that we are clearing bit 0 instead of setting it, blocking communication between these two blocks; due to that, any display that is connected to DSI0 will not work, as no data will go through. The effect of that issue is that, during bootup, the DRM will block for some time, while atomically waiting for a vblank that never happens; later, the situation doesn't get better, leaving the display in a non-functional state. To fix this issue, fix the route entry in the table by assigning the dither input selector to MT8192_DISP_DSI0_SEL_IN.

2022-02-28Input: goodix - fix race on driver unbindHans de Goede2-13/+23
Because there is no way to detect if the touchscreen has pen support, the driver is allocating and registering the input_pen input_dev on receiving the first pen event. But this means that the input_dev gets allocated after the request_irq() call which means that the devm framework will free it before disabling the irq, leaving a window where the irq handler may run and reference the free-ed input_dev. To fix this move the allocation of the input_pen input_dev to before the request_irq() call, while still only registering it on the first pen event so that the driver does not advertise pen capability on touchscreens without it (most goodix touchscreens do not have pen support).

2022-02-28Input: set EV_ABS in dev->evbit even if input_alloc_absinfo() failsHans de Goede1-6/+3
The input core's error handling for input_alloc_absinfo() failures is based on ignoring the error until input_register_device() runs and then checks for the failure like this: if (test_bit(EV_ABS, dev->evbit) && !dev->absinfo) { dev_err(&dev->dev, ...); return -EINVAL; } This relies on EV_ABS actually getting set in dev->evbit even if input_alloc_absinfo() fails, change input_set_abs_params() and input_set_capability() to actually adhere to this.

Interrupt() resource ACPI/x86 devices with a Cherry Trail SoC should have a GpioInt + a regular GPIO ACPI resource in their ACPI tables. Some CHT devices have a bug, where the also is bogus interrupt resource (likely copied from a previous Bay Trail based generation of the device). The i2c-core-acpi code will assign the bogus, non-working, interrupt resource to client->irq. Add a workaround to fix this up.

2022-02-28pinctrl: sunxi: Use unique lockdep classes for IRQsSamuel Holland1-0/+9
This driver, like several others, uses a chained IRQ for each GPIO bank, and forwards .irq_set_wake to the GPIO bank's upstream IRQ. As a result, a call to irq_set_irq_wake() needs to lock both the upstream and downstream irq_desc's. Lockdep considers this to be a possible deadlock when the irq_desc's share lockdep classes, which they do by default: ============================================ WARNING: possible recursive locking detected 5.17.0-rc3-00394-gc849047c2473 #1 Not tainted -------------------------------------------- init/307 is trying to acquire lock: c2dfe27c (&irq_desc_lock_class){-.-.}-{2:2}, at: __irq_get_desc_lock+0x58/0xa0 but task is already holding lock: c3c0ac7c (&irq_desc_lock_class){-.-.}-{2:2}, at: __irq_get_desc_lock+0x58/0xa0 other info that might help us debug this: Possible unsafe locking scenario: CPU0 ---- lock(&irq_desc_lock_class); lock(&irq_desc_lock_class); *** DEADLOCK *** May be due to missing lock nesting notation 4 locks held by init/307: #0: c1f29f18 (system_transition_mutex){+.+.}-{3:3}, at: __do_sys_reboot+0x90/0x23c #1: c20f7760 (&dev->mutex){....}-{3:3}, at: device_shutdown+0xf4/0x224 #2: c2e804d8 (&dev->mutex){....}-{3:3}, at: device_shutdown+0x104/0x224 #3: c3c0ac7c (&irq_desc_lock_class){-.-.}-{2:2}, at: __irq_get_desc_lock+0x58/0xa0 stack backtrace: CPU: 0 PID: 307 Comm: init Not tainted 5.17.0-rc3-00394-gc849047c2473 #1 Hardware name: Allwinner sun8i Family unwind_backtrace from show_stack+0x10/0x14 show_stack from dump_stack_lvl+0x68/0x90 dump_stack_lvl from __lock_acquire+0x1680/0x31a0 __lock_acquire from lock_acquire+0x148/0x3dc lock_acquire from _raw_spin_lock_irqsave+0x50/0x6c _raw_spin_lock_irqsave from __irq_get_desc_lock+0x58/0xa0 __irq_get_desc_lock from irq_set_irq_wake+0x2c/0x19c irq_set_irq_wake from irq_set_irq_wake+0x13c/0x19c [tail call from sunxi_pinctrl_irq_set_wake] irq_set_irq_wake from gpio_keys_suspend+0x80/0x1a4 gpio_keys_suspend from gpio_keys_shutdown+0x10/0x2c gpio_keys_shutdown from device_shutdown+0x180/0x224 device_shutdown from __do_sys_reboot+0x134/0x23c __do_sys_reboot from ret_fast_syscall+0x0/0x1c However, this can never deadlock because the upstream and downstream IRQs are never the same (nor do they even involve the same irqchip).

Here is call path: intel_pasid_alloc_table pci_for_each_dma_alias get_alias_pasid_table search_pasid_table pci_real_dma_dev() in pci_for_each_dma_alias() gets the real dma device which is the VMD device 0000:59:00.5. However, pte of the VMD device 0000:59:00.5 has been configured during this message "pci 0000:59:00.5: Adding to iommu group 42". So, the status -EBUSY is returned when configuring pasid entry for device 10000:80:01.0. It then invokes dmar_remove_one_dev_info() to release 'struct device_domain_info *' from iommu_devinfo_cache. But, the pasid table is not released because of the following statement in __dmar_remove_one_dev_info(): if (info->dev && !dev_is_real_dma_subdevice(info->dev)) { ... intel_pasid_free_table(info->dev); } The subsequent dmar_insert_one_dev_info() operation of device 10000:80:03.0 allocates 'struct device_domain_info *' from iommu_devinfo_cache. The allocated address is the same address that is released previously for device 10000:80:01.0. Finally, invoking device_attach_pasid_table() causes the issue. `git bisect` points to the offending commit 474dd1c65064 ("iommu/vt-d: Fix clearing real DMA device's scalable-mode context entries"), which releases the pasid table if the device is not the subdevice by checking the returned status of dev_is_real_dma_subdevice(). Reverting the offending commit can work around the issue. The solution is to prevent from allocating pasid table if those devices are subdevices of the VMD device.

This JSP2 PCH actually seems to be some special Apple specific ICP variant rather than a JSP. Make it so. Or at least all the references to it seem to be some Apple ICL machines. Didn't manage to find these PCI IDs in any public chipset docs unfortunately. The only thing we're losing here with this JSP->ICP change is Wa_14011294188, but based on the HSD that isn't actually needed on any ICP based design (including JSP), only TGP based stuff (including MCC) really need it. The documented w/a just never made that distinction because Windows didn't want to differentiate between JSP and MCC (not sure how they handle hpd/ddc/etc. then though...).

2022-02-28net: ipa: fix a build dependencyAlex Elder1-0/+1
An IPA build problem arose in the linux-next tree the other day. The problem is that a recent commit adds a new dependency on some code, and the Kconfig file for IPA doesn't reflect that dependency. As a result, some configurations can fail to build (particularly when COMPILE_TEST is enabled). The recent patch adds calls to qmp_get(), qmp_put(), and qmp_send(), and those are built based on the QCOM_AOSS_QMP config option. If that symbol is not defined, stubs are defined, so we just need to ensure QCOM_AOSS_QMP is compatible with QCOM_IPA, or it's not defined.

2022-02-28arm64: dts: mt8183: jacuzzi: Fix bus properties in anx's DSI endpointNícolas F. R. A. Prado1-0/+2
mt8183-kukui-jacuzzi has an anx7625 bridge connected to the output of its DSI host. However, after commit fd0310b6fe7d ("drm/bridge: anx7625: add MIPI DPI input feature"), a bus-type property started being required in the endpoint node by the driver to indicate whether it is DSI or DPI. Add the missing bus-type property and set it to 5 (V4L2_FWNODE_BUS_TYPE_PARALLEL) so that the driver has its input configured to DSI and the display pipeline can probe correctly. While at it, also set the data-lanes property that was also introduced in that same commit, so that we don't rely on the default value.

2022-02-28net: ipv6: ensure we call ipv6_mc_down() at most once[email protected]1-2/+6
There are two reasons for addrconf_notify() to be called with NETDEV_DOWN: either the network device is actually going down, or IPv6 was disabled on the interface. If either of them stays down while the other is toggled, we repeatedly call the code for NETDEV_DOWN, including ipv6_mc_down(), while never calling the corresponding ipv6_mc_up() in between. This will cause a new entry in idev->mc_tomb to be allocated for each multicast group the interface is subscribed to, which in turn leaks one struct ifmcaddr6 per nontrivial multicast group the interface is subscribed to. The following reproducer will leak at least $n objects: ip addr add ff2e::4242/32 dev eth0 autojoin sysctl -w net.ipv6.conf.eth0.disable_ipv6=1 for i in $(seq 1 $n); do ip link set up eth0; ip link set down eth0 done Joining groups with IPV6_ADD_MEMBERSHIP (unprivileged) or setting the sysctl net.ipv6.conf.eth0.forwarding to 1 (=> subscribing to ff02::2) can also be used to create a nontrivial idev->mc_list, which will the leak objects with the right up-down-sequence. Based on both sources for NETDEV_DOWN events the interface IPv6 state should be considered: - not ready if the network interface is not ready OR IPv6 is disabled for it - ready if the network interface is ready AND IPv6 is enabled for it The functions ipv6_mc_up() and ipv6_down() should only be run when this state changes. Implement this by remembering when the IPv6 state is ready, and only run ipv6_mc_down() if it actually changed from ready to not ready. The other direction (not ready -> ready) already works correctly, as: - the interface notification triggered codepath for NETDEV_UP / NETDEV_CHANGE returns early if ipv6 is disabled, and - the disable_ipv6=0 triggered codepath skips fully initializing the interface as long as addrconf_link_ready(dev) returns false - calling ipv6_mc_up() repeatedly does not leak anything Fixes: 3ce62a84d53c ("ipv6: exit early in addrconf_notify() if IPv6 is disabled") Signed-off-by: Johannes Nixdorf <[email protected]> Signed-off-by: David S.

2022-02-28efivars: Respect "block" flag in efivar_entry_set_safe()Jann Horn1-1/+4
When the "block" flag is false, the old code would sometimes still call check_var_size(), which wrongly tells ->query_variable_store() that it can block. As far as I can tell, this can't really materialize as a bug at the moment, because ->query_variable_store only does something on X86 with generic EFI, and in that configuration we always take the efivar_entry_set_nonblocking() path.
