Subject: [PATCH v5 0/7] net/eth: Fix stack-buffer-overflow in _eth_get_rss_ex_dst_addr()
Date: Wed, 10 Mar 2021 17:01:28 +0100 [thread overview]
Message-ID: <20210310160135.1148272-1-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 v4:
- reworked again, tested it with Fedora Raw Hide
Philippe Mathieu-Daudé (7):
net/eth: Simplify _eth_get_rss_ex_dst_addr()
net/eth: Better describe _eth_get_rss_ex_dst_addr's offset argument
net/eth: Make ip6_ext_hdr *ext_hdr pointer to const
net/eth: Check the size earlier
net/eth: Check iovec has enough data earlier
net/eth: Read ip6_ext_hdr_routing buffer before accessing it
net/eth: Add an assert() and invert if() statement to simplify code
