Hi Jason, Greetings, I'm a PhD student interested in linux, I found a bug in drivers/infiniband/core/uverbs_cmd.c via static analysis. As a follow-up, I planned to fuzz testing this driver using syzkaller to confirm this. However, according to the doc in Documentation/infiniband/user_verbs.rst, (it's a bit out-dated BTW, as CONFIG_INFINIBAND_USER_VERBS is not used anymore). I built the kernel with all related options set to y, installed libibverbs-dev, and added KERNEL="uverbs*", NAME="infiniband/%k" to my udev rule. there is no 'uverbs0' file created under /sys/class/infiniband or /dev/infiniband/. So may I ask how to properly set up my testing environment so that I can fuzzi testing this driver? Is a physical device required? Any information is greatly appreciated. Best, Changming Liu
