## Summary virtio_9p_request() gave each buffer to the device as one descriptor, and libmetal translates only its start address. In a kernel build a buffer in a user address environment is contiguous only in virtual memory, so a read that crossed a page wrote into whatever physical page followed the first one. QEMU stops the device with "virtio: bogus descriptor or out of resources" when that range leaves guest memory. With CONFIG_ARCH_ADDRENV, split each buffer at the pages that are not physically adjacent. ## Impact RELEASE ## Testing CI -- This is an automated message from the Apache Git Service.
