Subject: [libnftables PATCH] utils: fix error path for nft_strtoi
Date: Mon, 19 Aug 2013 14:37:30 +0200 [thread overview]
Message-ID: <20130819123729.21346.17925.stgit@nfdev.cica.es> (raw)
If the return of nft_get_value() is not evaluated, we don't know if the parsed
value is between the limits of his type.
