QEMU fuzzer reported a buffer overflow in _eth_get_rss_ex_dst_addr()
reproducible as:

  SUMMARY: AddressSanitizer: stack-buffer-overflow net/eth.c:410:17 in _eth_get_rss_ex_dst_addr

    Addressable:           00

    Stack left redzone:      f1
    Stack right redzone:     f3
  ==2859770==ABORTING

Similarly GCC 11 reports:

  net/eth.c: In function 'eth_parse_ipv6_hdr':
  net/eth.c:410:15: error: array subscript 'struct ip6_ext_hdr_routing[0]' is partly outside array bounds of 'struct ip6_ext_hdr[1]' [-Werror=array-bounds]
    410 |     if ((rthdr->rtype == 2) && (rthdr->segleft == 1)) {
        |          ~~~~~^~~~~~~
  net/eth.c:485:24: note: while referencing 'ext_hdr'
    485 |     struct ip6_ext_hdr ext_hdr;
        |                        ^~~~~~~
  net/eth.c:410:38: error: array subscript 'struct ip6_ext_hdr_routing[0]' is partly outside array bounds of 'struct ip6_ext_hdr[1]' [-Werror=array-bounds]
    410 |     if ((rthdr->rtype == 2) && (rthdr->segleft == 1)) {
        |                                 ~~~~~^~~~~~~~~
  net/eth.c:485:24: note: while referencing 'ext_hdr'
    485 |     struct ip6_ext_hdr ext_hdr;
        |                        ^~~~~~~

In eth_parse_ipv6_hdr() we called iov_to_buf() to fill the 2 bytes of
the 'ext_hdr' buffer, then _eth_get_rss_ex_dst_addr() tries to access
beside the 2 filled bytes.

Fix by reworking the function, filling the full rt_hdr buffer on the
stack calling iov_to_buf() again.

Add the corresponding qtest case with the fuzzer reproducer.

Want to apply but it doesn't apply on master:

Applying: net/eth: Fix stack-buffer-overflow in _eth_get_rss_ex_dst_addr()
error: sha1 information is lacking or useless (MAINTAINERS).
error: could not build fake ancestor
Patch failed at 0002 net/eth: Fix stack-buffer-overflow in 
_eth_get_rss_ex_dst_addr()

Thanks

From the cover:

Based-on: <20210115150936.3333282-1-philmd@redhat.com>
          "tests/qtest: Fixes fuzz-tests"

I'll check/ping the other series.

Thanks,
