2024-09-20ntb: Force physically contiguous allocation of rx ring buffersDave Jiang1-5/+18
Physical addresses under IOVA on x86 platform are mapped contiguously as a side effect before the patch that removed CONFIG_DMA_REMAP. The NTB rx buffer ring is a single chunk DMA buffer that is allocated against the NTB PCI device. If the receive side is using a DMA device, then the buffers are remapped against the DMA device before being submitted via the dmaengine API. This scheme becomes a problem when the physical memory is discontiguous. When dma_map_page() is called on the kernel virtual address from the dma_alloc_coherent() call, the new IOVA mapping no longer points to all the physical memory allocated due to being discontiguous. Change dma_alloc_coherent() to dma_alloc_attrs() in order to force DMA_ATTR_FORCE_CONTIGUOUS attribute. This is the best fix for the circumstance. A potential future solution may be having the DMA mapping API providing a way to alias an existing IOVA mapping to a new device perhaps. This fix is not to fix the patch pointed to by the fixes tag, but to fix the issue arised in the ntb_transport driver on x86 platforms after the said patch is applied.

2024-09-20ntb: ntb_hw_switchtec: Fix use after free vulnerability in ↵Kaixin Wang1-0/+1
switchtec_ntb_remove due to race condition In the switchtec_ntb_add function, it can call switchtec_ntb_init_sndev function, then &sndev->check_link_status_work is bound with check_link_status_work. switchtec_ntb_link_notification may be called to start the work. If we remove the module which will call switchtec_ntb_remove to make cleanup, it will free sndev through kfree(sndev), while the work mentioned above will be used. The sequence of operations that may lead to a UAF bug is as follows: CPU0 CPU1 | check_link_status_work switchtec_ntb_remove | kfree(sndev); | | if (sndev->link_force_down) | // use sndev Fix it by ensuring that the work is canceled before proceeding with the cleanup in switchtec_ntb_remove.

git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux Pull i2c fixes from Wolfram Sang: "The Aspeed driver tracks the controller's state (stop, pending, start, etc.). Previously, when the stop command was sent, the state was not updated. The fix ensures the driver's state is aligned with the device status. The Intel SCH driver receives a new look, and among the cleanups, there is a fix where, due to an oversight, an if/else statement was missing the else, causing it to move forward instead of exiting the function in case of an error. The Qualcomm GENI I2C driver adds the IRQF_NO_AUTOEN flag to the IRQ setup to prevent unwanted interrupts during probe. The Xilinx XPS controller fixes TX FIFO handling to avoid missed NAKs.
