[PATCH v4.19.y, v4.14.y, v4.9.y] crypto: drbg - add FIPS 140-2 CTRNG for noise source

by Vikash Bansal

From: Stephan Mueller <smueller(a)chronox.de> commit db07cd26ac6a418dc2823187958edcfdb415fa83 upstream FIPS 140-2 section 4.9.2 requires a continuous self test of the noise source. Up to kernel 4.8 drivers/char/random.c provided this continuous self test. Afterwards it was moved to a location that is inconsistent with the FIPS 140-2 requirements. The relevant patch was e192be9d9a30555aae2ca1dc3aad37cba484cd4a . Thus, the FIPS 140-2 CTRNG is added to the DRBG when it obtains the seed. This patch resurrects the function drbg_fips_continous_test that existed some time ago and applies it to the noise sources. The patch that removed the drbg_fips_continous_test was b3614763059b82c26bdd02ffcb1c016c1132aad0 . The Jitter RNG implements its own FIPS 140-2 self test and thus does not need to be subjected to the test in the DRBG. The patch contains a tiny fix to ensure proper zeroization in case of an error during the Jitter RNG data gathering.

[PATCH v2] iommu/dma: Fix MSI reservation allocation

by Marc Zyngier

The way cookie_init_hw_msi_region() allocates the iommu_dma_msi_page structures doesn't match the way iommu_put_dma_cookie() frees them. The former performs a single allocation of all the required structures, while the latter tries to free them one at a time. It doesn't quite work for the main use case (the GICv3 ITS where the range is 64kB) when the base granule size is 4kB. This leads to a nice slab corruption on teardown, which is easily observable by simply creating a VF on a SRIOV-capable device, and tearing it down immediately (no need to even make use of it). Fortunately, this only affects systems where the ITS isn't translated by the SMMU, which are both rare and non-standard. Fix it by allocating iommu_dma_msi_page structures one at a time.

[Patch] media: ti-vpe: cal: fix a kernel oops when unloading module

by Benoit Parrot

After the switch to use v4l2_async_notifier_add_subdev() and v4l2_async_notifier_cleanup(), unloading the ti_cal module would casue a kernel oops. This was root cause to the fact that v4l2_async_notifier_cleanup() tries to kfree the asd pointer passed into v4l2_async_notifier_add_subdev(). In our case the asd reference was from a statically allocated struct. So in effect v4l2_async_notifier_cleanup() was trying to free a pointer that was not kalloc. So here we switch to using a kzalloc struct instead of a static one.

patch "driver core: Call sync_state() even if supplier has no consumers" added to driver-core-linus

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled driver core: Call sync_state() even if supplier has no consumers to my driver-core git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core.git in the driver-core-linus branch. The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.) The patch will hopefully also be merged in Linus's tree for the next -rc kernel release.

This was because when a device is successfully bound with a driver, only its suppliers were checked to see if they are eligible to get a sync_state(). This is not sufficient for devices that have no consumers but still need to do device state clean up. So fix this.

[PATCH v2 1/4] PM / Domains: Allow no domain-idle-states DT property in genpd when parsing

by Ulf Hansson

Commit 2c361684803e ("PM / Domains: Don't treat zero found compatible idle states as an error"), moved of_genpd_parse_idle_states() towards allowing none compatible idle state to be found for the device node, rather than returning an error code. However, it didn't consider that the "domain-idle-states" DT property may be missing as it's optional, which makes of_count_phandle_with_args() to return -ENOENT. Let's fix this to make the behaviour consistent.

[PATCH] vfio: platform: Switch to platform_get_irq_optional()

by Eric Auger

Since commit 7723f4c5ecdb ("driver core: platform: Add an error message to platform_get_irq*()"), platform_get_irq() calls dev_err() on an error. As we enumerate all interrupts until platform_get_irq() fails, we now systematically get a message such as: "vfio-platform fff51000.ethernet: IRQ index 3 not found" which is a false positive. Let's use platform_get_irq_optional() instead.

patch "usb: dwc3: gadget: Update chain bit correctly when using sg list" added to usb-linus

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled usb: dwc3: gadget: Update chain bit correctly when using sg list to my usb git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb.git in the usb-linus branch. The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.) The patch will hopefully also be merged in Linus's tree for the next -rc kernel release. If you have any questions about this process, please let me know. >From dad2aff3e827b112f27fa5e6f2bf87a110067c3f Mon Sep 17 00:00:00 2001 From: Pratham Pratap <prathampratap(a)codeaurora.org> Date: Mon, 2 Mar 2020 21:44:43 +0000 Subject: usb: dwc3: gadget: Update chain bit correctly when using sg list If scatter-gather operation is allowed, a large USB request is split into multiple TRBs. For preparing TRBs for sg list, driver iterates over the list and creates TRB for each sg and mark the chain bit to false for the last sg. The current IOMMU driver is clubbing the list of sgs which shares a page boundary into one and giving it to USB driver. With this the number of sgs mapped it not equal to the the number of sgs passed. Because of this USB driver is not marking the chain bit to false since it couldn't iterate to the last sg. This patch addresses this issue by marking the chain bit to false if it is the last mapped sg. At a practical level, this patch resolves USB transfer stalls seen with adb on dwc3 based db845c, pixel3 and other qcom hardware after functionfs gadget added scatter-gather support around v4.20.
