The way to go is to link UBSan into ASan/TSan/etc. I'm doing this in LLVM ones here: http://netbsd.org/~kamil/llvm/llvm-sanitizers-patch1.txt Additionally ASan should link LSan code. We apparently want more tests in ATF verifying *San + UBSan used concurrently. signature.asc Description: OpenPGP digital signature

The change Roy made is something I also perform systematically on any system I install and expect to connect to a wireless networks. It is harmless when wpa_supplicant(8) is not running. I agree that a dedicated group to allow network configuration would be nice. However users in the "wheel" group are usually expected to be allowed to su(1) anyway, and I think the balance is already very good with this group to perform the corresponding privileged operations without prompting for a password nor exposing too much.

Looks like kernel goes infinite loop in usbd_ar_pipe by some reason.
