From mboxrd@z Thu Jan 1 00:00:00 1970 From: Bruce Richardson Subject: [PATCH] testpmd: limit port mask bits to RTE_MAX_ETHPORTS Date: Tue, 16 Dec 2014 13:27:17 +0000 Message-ID: <1418736437-30585-1-git-send-email-bruce.richardson@intel.com> To: dev-VfR2kkLFssw@public.gmane.org Return-path: List-Id: patches and discussions about DPDK List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Errors-To: dev-bounces-VfR2kkLFssw@public.gmane.org Sender: "dev" The port mask parsing in testpmd allowed up to 64 bits to be processed, even if RTE_MAX_ETHPORTS is set to a max of 32. Fix this by only processing up to min(RTE_MAX_ETHPORTS,64) bits of the mask.
