Subject: dpdk: increase buffer size for parsing lcores
X-Git-Url: https://git.verplant.org/?a=commitdiff_plain;h=1fa33c8280426163249b149843b2dbcdb0471ec3;p=collectd.git

dpdk: increase buffer size for parsing lcores

This commit increases the size of the "high_str" buffer,
which is later used by the strncpy() function. Static analysis
showed that there was a potential issue in accessing this string
if the buffer is smaller.
