I think the ioctl()'s are good. I think that they just changed on how they
get the interface, and just down lo, intead of lo:1.
with 1.35 I get:
socket(PF_INET, SOCK_DGRAM, IPPROTO_IP) = 3
socket(0xa /* PF_??? */, SOCK_DGRAM, 0) = 4
socket(0x5 /* PF_??? */, SOCK_DGRAM, 0) = -1 ENOSYS (Function not
implemented)
socket(0x5 /* PF_??? */, SOCK_DGRAM, 0) = -1 ENOSYS (Function not
implemented)
socket(0x5 /* PF_??? */, SOCK_DGRAM, 0request_module[net-pf-5]:
waitpid(7757,...) failed, errno 1
) = -1 EINVAL (Invalid argument)
ioctl(3, SIOCGIFFLAGS, 0xbffff8d8) = 0
ioctl(3, SIOCSIFFLAGS, 0xbffff8d8) = 0
with 1.36 I get:
access("/proc", R_OK) = 0
socket(PF_INET, SOCK_DGRAM, IPPROTO_IP) = 3
socket(PF_INET, SOCK_DGRAM, IPPROTO_IP) = 4
access("/proc/net/if_inet6", R_OK) = 0
socket(0xa /* PF_??? */, SOCK_DGRAM, 0) = 5
ioctl(5, SIOCGIFFLAGS, 0xbffff8c8) = 0
ioctl(5, SIOCSIFFLAGS, 0xbffff8c8) = 0
You'll notice that it now checks /proc.
But afaik, the ioctl should be called with the same arguments. It's not
making much sense to me.
