commit bf43e452 upstream. Always run fbdev removal first to remove simpledrm via sysfb_disable(). This clears the internal state. The later call to drm_aperture_detach_drivers() then does nothing. Otherwise, with drm_aperture_detach_drivers() running first, the call to sysfb_disable() uses inconsistent state.

commit 230ec83d upstream. x86_has_pat_wp() is using a wrong test, as it relies on the normal PAT configuration used by the kernel. In case the PAT MSR has been setup by another entity (e.g. Xen hypervisor) it might return false even if the PAT configuration is allowing WP mappings. This due to the fact that when running as Xen PV guest the PAT MSR is setup by the hypervisor and cannot be changed by the guest. This results in the WP related entry to be at a different position when running as Xen PV guest compared to the bare metal or fully virtualized case. The correct way to test for WP support is: 1. Get the PTE protection bits needed to select WP mode by reading __cachemode2pte_tbl[_PAGE_CACHE_MODE_WP] (depending on the PAT MSR setting this might return protection bits for a stronger mode, e.g. UC-) 2. Translate those bits back into the real cache mode selected by those PTE bits by reading __pte2cachemode_tbl[__pte2cm_idx(prot)] 3. Test for the cache mode to be _PAGE_CACHE_MODE_WP Fixes: f88a68fa ("x86/mm: Extend early_memremap() support with additional attrs") Signed-off-by: Juergen Gross <jgross@suse.com> Signed-off-by: Borislav Petkov <bp@suse.de> Cc: <stable@vger.kernel.org> # 4.14 Link: https://lore.kernel.org/r/20220503132207.17234-1-jgross@suse.com Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

commit f9b11229 upstream. When console is enabled, univ8250_console_setup() calls serial8250_console_setup() before .dev is set to uart_port. Therefore, it will not call pm_runtime_get_sync(). Later, when the actual driver is going to take over univ8250_console_exit() is called. As .dev is already set, serial8250_console_exit() makes pm_runtime_put_sync() call with usage count being zero triggering PM usage count warning (extra debug for univ8250_console_setup(), univ8250_console_exit(), and serial8250_register_ports()): [ 0.068987] univ8250_console_setup ttyS0 nodev [ 0.499670] printk: console [ttyS0] enabled [ 0.717955] printk: console [ttyS0] printing thread started [ 1.960163] serial8250_register_ports assigned dev for ttyS0 [ 1.976830] printk: console [ttyS0] disabled [ 1.976888] printk: console [ttyS0] printing thread stopped [ 1.977073] univ8250_console_exit ttyS0 usage:0 [ 1.977075] serial8250 serial8250: Runtime PM usage count underflow!

commit 39cdb68c upstream. A memory overlapping copy occurs when deleting a long line. This memory overlapping copy can cause data corruption when scr_memcpyw is optimized to memcpy because memcpy does not ensure its behavior if the destination buffer overlaps with the source buffer. The line buffer is not always broken, because the memcpy utilizes the hardware acceleration, whose result is not deterministic. Fix this problem by using replacing the scr_memcpyw with scr_memmovew.

commit 7441b273 upstream. The DWC3_EVENT_PENDING flag is used to protect against invalid call to top-half interrupt handler, which can occur when there's a delay in software detection of the interrupt line deassertion. However, the clearing of this flag was done prior to unmasking the interrupt line, creating opportunity where the top-half handler can come. This breaks the serialization and creates a race between the top-half and bottom-half handler, resulting in losing synchronization between the controller and the driver when processing events. To fix this, make sure the clearing of the DWC3_EVENT_PENDING is done at the end of the bottom-half handler.

[ Upstream commit a382f8fe ] These are indeed "should not happen" situations, but it turns out recent changes made the 'task_is_stopped_or_trace()' case trigger (fix for that exists, is pending more testing), and the BUG_ON() makes it unnecessarily hard to actually debug for no good reason. It's been that way for a long time, but let's make it clear: BUG_ON() is not good for debugging, and should never be used in situations where you could just say "this shouldn't happen, but we can continue". Use WARN_ON_ONCE() instead to make sure it gets logged, and then just continue running. Instead of making the system basically unusuable because you crashed the machine while potentially holding some very core locks (eg this function is commonly called while holding 'tasklist_lock' for writing).

[ Upstream commit 4fb7c24f ] Fiero SC-01 is a USB sound card with two mono inputs and a single stereo output. The inputs are composed into a single stereo stream. The device uses a vendor-provided driver on Windows and does not work at all without it. The driver mostly provides ASIO functionality, but also alters the way the sound card is queried for sample rates and clocks. ALSA queries those failing with an EPIPE (same as Windows 10 does). Presumably, the vendor-provided driver does not query it at all, simply matching by VID:PID. Thus, I consider this a buggy firmware and adhere to a set of fixed endpoint quirks instead. The soundcard has an internal clock. Implicit feedback mode is required for the playback. I have updated my device to v1.1.0 from a Windows 10 VM using a vendor- provided binary prior to the development, hoping for it to just begin working. The device provides no obvious way to downgrade the firmware, and regardless, there's no binary available for v1.0.0 anyway. Thus, I will be getting another unit to extend the patch with support for that. Expected to be a simple copy-paste of the existing one, though. There were no previous reports of that device in context of Linux anywhere. Other issues have been reported though, but that's out of the scope.

[ Upstream commit 11d7a12f ] DAPM keeps a copy of the current value of mux/demux controls, however this value is only initialised in the case of autodisable controls. This leads to false notification events when first modifying a DAPM kcontrol that has a non-zero default. Autodisable controls are left as they are, since they already initialise the value, and there would be more work required to support autodisable muxes where the first option isn't disabled and/or that isn't the default. Technically this issue could affect mixer/switch elements as well, although not on any of the devices I am currently running. There is also a little more work to do to address the issue there due to that side supporting stereo controls, so that has not been tackled in this patch.

[ Upstream commit 10e7ff00 ] Currently wcd938x_*_put() unconditionally report that the value of the control changed, resulting in spurious events being generated. Return 0 in that case instead as we should. There is still an issue in the compander control which is a bit more complex.

[ Upstream commit bbfef046 ] Update the comment for the cl_dsp_init() to clarify what is done by the function and use the chip->init_core_mask instead of BIT(0) when unstalling/running the init core.

[ Upstream commit ba98d7d8 ] The workqueues are initialized in the io_init functions, which isn't quite right. In some tests, this leads to warnings throw from __queue_delayed_work() WARN_ON_FUNCTION_MISMATCH(timer->function, delayed_work_timer_fn); Move all the initializations to the probe functions.

[ Upstream commit 0484271a ] Realtek headset codec drivers typically check if the card is instantiated before proceeding with the jack detection. The rt700, rt711 and rt711-sdca are however missing a check on the card pointer, which can lead to NULL dereferences encountered in driver bind/unbind tests.

[ Upstream commit fe154c4f ] If the card registration fails, typically because of deferred probes, the device properties added for headset codecs are not removed, which leads to kernel oopses in driver bind/unbind tests. We already clean-up the device properties when the card is removed, this code can be moved as a helper and called upon card registration errors.
