RDMA/i40iw: Address an mmap handler exploit in i40iw

2020-12-08T09:17:34Z

commit 2ed381439e89fa6d1a0839ef45ccd45d99d8e915 upstream. i40iw_mmap manipulates the vma->vm_pgoff to differentiate a push page mmap vs a doorbell mmap, and uses it to compute the pfn in remap_pfn_range without any validation. This is vulnerable to an mmap exploit as described in: https://lore.kernel.org/r/20201119093523.7588-1-zhudi21@huawei.com The push feature is disabled in the driver currently and therefore no push mmaps are issued from user-space. The feature does not work as expected in the x722 product. Remove the push module parameter and all VMA attribute manipulations for this feature in i40iw_mmap. Update i40iw_mmap to only allow DB user mmapings at offset = 0. Check vm_pgoff for zero and if the mmaps are bound to a single page.

Input: i8042 - add ByteSpeed touchpad to noloop table

2020-12-08T09:17:34Z

commit a48491c65b513e5cdc3e7a886a4db915f848a5f5 upstream. It looks like the C15B laptop got another vendor: ByteSpeed LLC. Avoid AUX loopback on this touchpad as well, thus input subsystem will be able to recognize a Synaptics touchpad in the AUX port.

dt-bindings: net: correct interrupt flags in examples

2020-12-08T09:17:34Z

[ Upstream commit 4d521943f76bd0d1e68ea5e02df7aadd30b2838a ] GPIO_ACTIVE_x flags are not correct in the context of interrupt flags. These are simple defines so they could be used in DTS but they will not have the same meaning: 1. GPIO_ACTIVE_HIGH = 0 = IRQ_TYPE_NONE 2. GPIO_ACTIVE_LOW = 1 = IRQ_TYPE_EDGE_RISING Correct the interrupt flags, assuming the author of the code wanted same logical behavior behind the name "ACTIVE_xxx", this is: ACTIVE_LOW => IRQ_TYPE_LEVEL_LOW ACTIVE_HIGH => IRQ_TYPE_LEVEL_HIGH Fixes: a1a8b4594f8d ("NFC: pn544: i2c: Add DTS Documentation") Fixes: 6be88670fc59 ("NFC: nxp-nci_i2c: Add I2C support to NXP NCI driver") Fixes: e3b329221567 ("dt-bindings: can: tcan4x5x: Update binding to use interrupt property") Signed-off-by: Krzysztof Kozlowski Acked-by: Rob Herring Acked-by: Marc Kleine-Budde # for tcan4x5x.txt Link: https://lore.kernel.org/r/20201026153620.89268-1-krzk@kernel.org Signed-off-by: Jakub Kicinski Signed-off-by: Greg Kroah-Hartman

net/mlx5: Fix wrong address reclaim when command interface is down

2020-12-08T09:17:34Z

[ Upstream commit 1d2bb5ad89f47d8ce8aedc70ef85059ab3870292 ] When command interface is down, driver to reclaim all 4K page chucks that were hold by the Firmeware. Fix a bug for 64K page size systems, where driver repeatedly released only the first chunk of the page. Define helper function to fill 4K chunks for a given Firmware pages. Iterate over all unreleased Firmware pages and call the hepler per each.

net/x25: prevent a couple of overflows

2020-12-08T09:17:33Z

[ Upstream commit 6ee50c8e262a0f0693dad264c3c99e30e6442a56 ] The .x25_addr[] address comes from the user and is not necessarily NUL terminated. This leads to a couple problems. The first problem is that the strlen() in x25_bind() can read beyond the end of the buffer. The second problem is more subtle and could result in memory corruption. The call tree is: x25_connect() --> x25_write_internal() --> x25_addr_aton() The .x25_addr[] buffers are copied to the "addresses" buffer from x25_write_internal() so it will lead to stack corruption. Verify that the strings are NUL terminated and return -EINVAL if they are not.
