Hi,
intelmetool occurs "segfault" on my laptop running Mint 18 with PaX/Grsecurity 4.7.10. The PCI info:
-[0000:00]-+-00.0 Intel Corporation Sky Lake Host Bridge/DRAM Registers [8086:1904] +-02.0 Intel Corporation Sky Lake Integrated Graphics [8086:1916] +-04.0 Intel Corporation Skylake Processor Thermal Subsystem [8086:1903] +-14.0 Intel Corporation Sunrise Point-LP USB 3.0 xHCI Controller [8086:9d2f] +-14.2 Intel Corporation Sunrise Point-LP Thermal subsystem [8086:9d31] +-15.0 Intel Corporation Sunrise Point-LP Serial IO I2C Controller [8086:9d60] +-15.1 Intel Corporation Sunrise Point-LP Serial IO I2C Controller [8086:9d61] +-16.0 Intel Corporation Sunrise Point-LP CSME HECI [8086:9d3a] +-1c.0-[01]----00.0 NVIDIA Corporation GM107M [GeForce GTX 960M] [10de:139b] +-1c.4-[02]----00.0 Samsung Electronics Co Ltd NVMe SSD Controller [144d:a802] +-1c.6-[03]----00.0 Qualcomm Atheros Killer E2400 Gigabit Ethernet Controller [1969:e0a1] +-1c.7-[04]----00.0 Qualcomm Atheros QCA6174 802.11ac Wireless Network Adapter [168c:003e] +-1d.0-[05]----00.0 Samsung Electronics Co Ltd NVMe SSD Controller [144d:a802] +-1d.2-[06-3e]-- +-1f.0 Intel Corporation Sunrise Point-LP LPC Controller [8086:9d48] +-1f.2 Intel Corporation Sunrise Point-LP PMC [8086:9d21] +-1f.3 Intel Corporation Sunrise Point-LP HD Audio [8086:9d70] -1f.4 Intel Corporation Sunrise Point-LP SMBus [8086:9d23]
The crash log was attached! I'm not sure if intelmetool support Skylake as well. One tiny feature of PaX/Grsecurity prevent the ioperm for killing the potential threats in case which the adversary re-flash the SPI ROM once they get the root priv. It does affect flashrom but intelmetool. I also ran intelmetool on the distro( Mint 18) kernel and got the same result.
