Subject: [dpdk-stable] patch 'ip_frag: use key length for key comparison' has been queued to LTS release 16.11.9
Date: Thu, 8 Nov 2018 18:01:06 +0000 [thread overview]
Message-ID: <20181108180111.25873-10-bluca@debian.org> (raw)
In-Reply-To: <20181108180111.25873-1-bluca@debian.org>
Hi,
FYI, your patch has been queued to LTS release 16.11.9
Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 11/10/18. So please
shout if anyone has objections.
Also note that after the patch there's a diff of the upstream commit vs the patch applied
to the branch. If the code is different (ie: not only metadata diffs), due for example to
a change in context or macro names, please double check it.
Thanks.
Luca Boccassi

Subject: [PATCH] ip_frag: use key length for key comparison
[ upstream commit b8d5dfd4a5f006794d85f93fc97134460ffbdfdf ]
Right now reassembly code relies on src_dst[] being all zeroes to
determine is it free/occupied entry in the fragments table.
This is suboptimal and error prone - user can crash DPDK ip_reassembly
app by something like the following scapy script:
x=Ether(src=...,dst=...)/IP(dst='0.0.0.0',src='0.0.0.0',id=0)/('X'*1000)
frags=fragment(x, fragsize=500)
sendp(frags, iface=...)
To overcome that issue and reduce overhead of
'key invalidate' and 'key is empty' operations -
add key_len into keys comparision procedure.
Fixes: 4f1a8f633862 ("ip_frag: add IPv6 reassembly")
