Using kdump, I see: text CALL pledge(0xb364f3d58bf,0) STRU promise="stdio inet sendfd" RET pledge 0
I noticed dhcpd pledges without bpf. According to the pledge(2) man page, bpf allows ioctl operations on bpf(4) devices. Could the missing bpf promise be the origin of the problem? Should pledge include bpf for dhcpd to work in non-global rdomains? I'm still an enthusiast tinkerer with OpenBSD, so I might be misunderstanding something.
