From: Olivier Matz Date: Wed, 4 Feb 2015 09:49:25 +0000 (+0100) Subject: cmdline: fix check in port list parsing X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=ac09cd97322fd3524082333aaab10885503eec83;p=dpdk.git cmdline: fix check in port list parsing The argument ressize contains the size of the result buffer which should be large enough to store the parsed result of a token. In this case, it should be larger or equal to sizeof(cmdline_portlist_t) (4 bytes), not PORTLIST_TOKEN_SIZE which is the max size of the token string. This is not a critical, it fixes cases where the total length of the parsed instruction is greater than the maximum.
