commit 3b89e4b7 upstream. A bugfix accidentally removed the implicit initialization of the dma channel number, causing undefined behavior when v->alloc_dma_channel is NULL: sound/soc/qcom/lpass-platform.c: In function ‘lpass_platform_pcmops_open’: sound/soc/qcom/lpass-platform.c:83:29: error: ‘dma_ch’ may be used uninitialized in this function [-Werror=maybe-uninitialized] This adds back an explicit initialization to zero, restoring the previous behavior for that case.

commit aec0e861 upstream. We met the DMAR fault both on hpsa P420i and P421 SmartArray controllers under kdump, it can be steadily reproduced on several different machines, the dmesg log is like: HP HPSA Driver (v 3.4.16-0) hpsa 0000:02:00.0: using doorbell to reset controller hpsa 0000:02:00.0: board ready after hard reset. hpsa 0000:02:00.0: Waiting for controller to respond to no-op DMAR: Setting identity map for device 0000:02:00.0 [0xe8000 - 0xe8fff] DMAR: Setting identity map for device 0000:02:00.0 [0xf4000 - 0xf4fff] DMAR: Setting identity map for device 0000:02:00.0 [0xbdf6e000 - 0xbdf6efff] DMAR: Setting identity map for device 0000:02:00.0 [0xbdf6f000 - 0xbdf7efff] DMAR: Setting identity map for device 0000:02:00.0 [0xbdf7f000 - 0xbdf82fff] DMAR: Setting identity map for device 0000:02:00.0 [0xbdf83000 - 0xbdf84fff] DMAR: DRHD: handling fault status reg 2 DMAR: [DMA Read] Request device [02:00.0] fault addr fffff000 [fault reason 06] PTE Read access is not set hpsa 0000:02:00.0: controller message 03:00 timed out hpsa 0000:02:00.0: no-op failed; re-trying After some debugging, we found that the fault addr is from DMA initiated at the driver probe stage after reset(not in-flight DMA), and the corresponding pte entry value is correct, the fault is likely due to the old iommu caches of the in-flight DMA before it. Thus we need to flush the old cache after context mapping is setup for the device, where the device is supposed to finish reset at its driver probe stage and no in-flight DMA exists hereafter. I'm not sure if the hardware is responsible for invalidating all the related caches allocated in the iommu hardware before, but seems not the case for hpsa, actually many device drivers have problems in properly resetting the hardware. Anyway flushing (again) by software in kdump kernel when the device gets context mapped which is a quite infrequent operation does little harm. With this patch, the problematic machine can survive the kdump tests.

commit 65ca7f5f upstream. Different encodings are used to represent supported PASID bits and number of PASID table entries. The current code assigns ecap_pss directly to extended context table entry PTS which is wrong and could result in writing non-zero bits to the reserved fields. IOMMU fault reason 11 will be reported when reserved bits are nonzero. This patch converts ecap_pss to extend context entry pts encoding based on VT-d spec. Chapter 9.4 as follows: - number of PASID bits = ecap_pss + 1 - number of PASID table entries = 2^(pts + 5) Software assigned limit of pasid_max value is also respected to match the allocation limitation of PASID table. cc: Mika Kuoppala <mika.kuoppala@linux.intel.com> cc: Ashok Raj <ashok.raj@intel.com> Signed-off-by:

commit 432abf68 upstream. The generic command buffer entry is 128 bits (16 bytes), so the offset of tail and head pointer should be 16 bytes aligned and increased with 0x10 per command. When cmd buf is full, head = (tail + 0x10) % CMD_BUFFER_SIZE. So when left space of cmd buf should be able to store only two command, we should be issued one COMPLETE_WAIT additionally to wait all older commands completed. Then the left space should be increased after IOMMU fetching from cmd buf. So left check value should be left <= 0x20 (two commands). Signed-off-by:

commit bae203d5 upstream. Function mx31_clocks_init() is called during clock intialization on legacy boards with reference clock frequency passed as its input argument, this can be verified by examination of the function declaration found in arch/arm/mach-imx/common.h and actual function users which include that header file. Inside CCF driver the function ignores its input argument, by chance the used value in the function body is the same as input arguments on side of all callers.

commit c0d04e91 upstream. Fix overflows seen when writing voltage and temperature limit attributes. The value passed to DIV_ROUND_CLOSEST() needs to be clamped, and the value parameter passed to nct7802_write_fan_min() is an unsigned long. Also, writing values larger than 2700000 into a fan limit attribute results in writing 0 into the chip's limit registers. The exact behavior when writing this value is unspecified. For consistency, report a limit of 1350000 if the chip register reads 0. This may be wrong, and the chip behavior should be verified with the actual chip, but it is better than reporting a value of 0 (which, when written, results in writing a value of 0x1fff into the chip register).

commit a608a9d5 upstream. All LED-setting functions in fujitsu-laptop are currently assigned to the brightness_set callback, which is incorrect because they can sleep (due to their use of call_fext_func(), which in turn issues ACPI calls) and the documentation (in include/linux/leds.h) clearly states they must not. Assign them to brightness_set_blocking instead and change them to match the expected function prototype. This change makes it possible to use Fujitsu-specific LEDs with "heavy" triggers, like disk-activity or phy0rx.

commit 7f847dd3 upstream. The slp_s0_residency_usec debugfs file currently uses DEFINE_DEBUGFS_ATTRIBUTE(), but that macro cannot really be used to define files outside of the debugfs code, as it has no reference to the get/set functions if CONFIG_DEBUG_FS is not defined: drivers/platform/x86/intel_pmc_core.c:80:12: error: ‘pmc_core_dev_state_get’ defined but not used [-Werror=unused-function] This fixes the macro to always contain the reference, and instead rely on the stubbed-out debugfs_create_file to not actually refer to its arguments so the compiler can still drop the reference. This works because the attribute definition is always 'static', and the dead-code removal silently drops all static symbols that are not used.

commit 2fa436b3 upstream. NL80211_ATTR_MAC was used to set both the specific BSSID to be scanned and the random MAC address to be used when privacy is enabled. When both the features are enabled, both the BSSID and the local MAC address were getting same value causing Probe Request frames to go with unintended DA. Hence, this has been fixed by using a different NL80211_ATTR_BSSID attribute to set the specific BSSID (which was the more recent addition in cfg80211) for a scan. Backwards compatibility with old userspace software is maintained to some extent by allowing NL80211_ATTR_MAC to be used to set the specific BSSID when scanning without enabling random MAC address use. Scanning with random source MAC address was introduced by commit ad2b26ab ("cfg80211: allow drivers to support random MAC addresses for scan") and the issue was introduced with the addition of the second user for the same attribute in commit 818965d3 ("cfg80211: Allow a scan request for a specific BSSID").

commit 1c3d185a upstream. On drivers setting the SUPPORTS_REORDERING_BUFFER hardware flag, we crash when the peer sends an AddBA request while we already have a session open on the seame TID; this is because on those drivers, the tid_agg_rx is left NULL even though the session is valid, and the agg_session_valid bit is set. To fix this, store the dialog tokens outside the tid_agg_rx to be able to compare them to the received AddBA request.

commit d4cb3fd9 upstream. Currently it's entirely possible to go through the link training step without first determining the lane_count, which is silly since we end up doing a bunch of aux transfers of size = 0, as highlighted by WARN_ON(!msg->buffer != !msg->size), and can only ever result in a 'failed to update link training' message. This can be observed during intel_dp_long_pulse where we can do the link training step, but before we have had a chance to set the link params. To avoid this we add an extra check for the lane_count in intel_dp_check_link_status, which should prevent us from doing the link training step prematurely. v2: add WARN_ON_ONCE and FIXME comment (Ville) References: https://bugs.freedesktop.org/show_bug.cgi?id=97344 Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Cc: Mika Kahola <mika.kahola@intel.com> Signed-off-by:

commit d6214592 upstream. commit 0416e494 ("usb: dwc3: ep0: correct cache sync issue in case of ep0_bounced") introduced a bug where we would leak DMA resources which would cause us to starve the system of them resulting in failing DMA transfers. Fix the bug by making sure that we always unmap EP0 requests since those are *always* mapped.

commit 65e4345c upstream. The LIS3LV02 has a special bit that need to be set to get the read values left aligned. Before this patch we get gibberish like this: iio_generic_buffer -a -c10 -n lis3lv02dl_accel (...) 0.000000 -0.010042 -0.642688 19155832931907 0.000000 -0.010042 -0.642688 19155858751073 Which is because we read a raw value for 1g as 64 which is the nominal 1024 for 1g shifted 4 bits to the left by being right-aligned rather than left aligned. Since all other sensors are left aligned, add some code to set the special DAS (data alignment setting) bit to 1 so that the right value is now read like this: iio_generic_buffer -a -c10 -n lis3lv02dl_accel (...) 0.000000 -0.147095 -10.120135 24761614364956 -0.029419 -0.176514 -10.120135 24761631624540 The scaling was weird as well: we have a gain of 1000 for 1g and 3000 for 6g.
