Donald Sharp [Wed, 15 Apr 2020 12:56:03 +0000 (08:56 -0400)]
zebra: Modify netlink_request to statisfy coverity

The netlink_request function takes a `struct nlmsghdr *`
pointer from a common pattern that we use:

struct {
struct nlmsghdr n;
struct fib_rule_hdr frh;
char buf[NL_PKT_BUF_SIZE];
} req;

We were calling it `netlink_request(Socket, &req.n)`

The problem here is that coverity, rightly so, sees that
we access the data after the nlmsghdr in netlink_request and
tells us we have an read beyond end of the structure.  While
we know we haven't mangled anything up here because of manual
inspection coverity doesn't have this knowledge implicitly.

So let's modify the code call to netlink_request to pass in the
void pointer of the req structure itself, cast to the appropriate
data structure in the function and do the right thing.  Hopefully
the coverity SA will be happy and we can move on with our life.

lib: handle failure to change ifindex

This fixes a theoretical bug that could occur when trying to change an
ifindex on an interface to that of an existing interface. We would
remove the interface from the ifindex tree, and change the ifindex, but
when we tried to reinsert the interface, the insert would fail. It was
impossible to know if this failed due to the insertion / deletion macros
capturing the result value of the underlying BSD tree macros. So we
would effectively delete the interface.

Instead of failing on insert, we just check if the prospective ifindex
already exists and return -1 if it does.

Macros have been changed to statement expressions so the result can be
checked, and bubbled up.
