Kristof Provost 14b5e85b18 pf: Fix possible out-of-bounds write ... In the DIOCRSETADDRS ioctl() handler we allocate a table for struct pfr_addrs, which is processed in pfr_set_addrs(). At the users request we also provide feedback on the deleted addresses, by storing them after the new list ('bcopy(&ad, addr + size + i, sizeof(ad));' in pfr_set_addrs()). This means we write outside the bounds of the buffer we've just allocated. We need to look at pfrio_size2 instead (i.e. the size the user reserved for our feedback). That'd allow a malicious user to specify a smaller pfrio_size2 than pfrio_size though, in which case we'd still read outside of the allocated buffer. Instead we allocate the largest of the two values.
