Subject: [PATCH v4 0/6] net/eth: Fix stack-buffer-overflow in _eth_get_rss_ex_dst_addr()
Date: Tue,  9 Mar 2021 19:27:03 +0100	[thread overview]
Message-ID: <20210309182709.810955-1-philmd@redhat.com> (raw)

I had a look at the patch from Miroslav trying to silence a
compiler warning which in fact is a nasty bug. Here is a fix.
https://www.mail-archive.com/qemu-devel@nongnu.org/msg772735.html

Since v3:
- reworked in multiple trivial patches (Stefano)
- reset R-b/A-b tags

Philippe Mathieu-Daudé (6):
  net/eth: Simplify _eth_get_rss_ex_dst_addr()
  net/eth: Better describe _eth_get_rss_ex_dst_addr's offset argument
  net/eth: Initialize input_size variable earlier
  net/eth: Check rt_hdr size before casting to ip6_ext_hdr
  net/eth: Remove now useless size check
  net/eth: Return earlier in _eth_get_rss_ex_dst_addr()
