Hi,
FYI, your patch has been queued to LTS release 18.11.9
Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 06/10/20. 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. This will indicate if there was any rebasing
needed to apply to the stable branch. If there were code changes for rebasing
(ie: not only metadata diffs), please double check that the rebase was
correctly done.
Queued patches are on a temporary branch at:
https://github.com/kevintraynor/dpdk-stable-queue
This queued commit can be viewed at:
https://github.com/kevintraynor/dpdk-stable-queue/commit/35d679a6265134c2e605e76f8bd9565bbccba333
Thanks.
Kevin.

Subject: [PATCH] kvargs: fix invalid token parsing on FreeBSD
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
[ upstream commit b2aa2c9723796d81cb9216f3a5c5e195796985fa ]
The behavior of strtok_r() is not the same between GNU libc and FreeBSD
libc: in the first case, the context is set to "" when the last token is
returned, while in the second case it is set to NULL.
On FreeBSD, the current code crashes because we are dereferencing a NULL
pointer (ctx1). Fix it by first checking if it is NULL. This works with
both GNU and FreeBSD libc.
Fixes: ffcf831454a9 ("kvargs: fix buffer overflow when parsing list")
