It will be pushed if I get no objections before 11/24/20. 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/60ea36a0a2673615056aec7f8585b7647fddf4ef Thanks. Kevin. --- From 60ea36a0a2673615056aec7f8585b7647fddf4ef Mon Sep 17 00:00:00 2001 From: Bruce Richardson <bruce.richardson@intel.com> Date: Wed, 28 Oct 2020 16:27:01 +0000 Subject: [PATCH] examples/multi_process: fix build on Ubuntu 20.04 MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit [ upstream commit 27b549c12df2ef2db6b271795b4df7b14a2d9c2c ] Two warnings are reported by gcc 9.3.0 on Ubuntu 20.04. When producing a printable mac address the buffer was appropriately sized for holding the mac address exactly, but the actual snprintf included a '\n' character at the end, which means that the snprintf technically is getting truncated i.e. the \n would not be added due to lack of space. This gets flagged as a problem by modern versions of gcc, e.g. on Ubuntu 20.04. main.c:77:37: warning: ‘__builtin___snprintf_chk’ output truncated before the last format character [-Wformat-truncation=] 77 | "%02x:%02x:%02x:%02x:%02x:%02x\n", | ^ Since the \n is getting stripped anyway, we can fix the issue by just removing it. In the process we can switch to using the standard ethernet address formatting function from rte_ether.h. The other warning is about possible string truncation when getting the RX queue name: In file included from init.c:36: init.c: In function ‘init’: ../shared/common.h:38:28: warning: ‘%u’ directive output may be truncated writing between 1 and 10 bytes into a region of size 8 [-Wformat-truncation=] 38 | #define MP_CLIENT_RXQ_NAME "MProc_Client_%u_RX" | ^~~~~~~~~~~~~~~~~~~~ ../shared/common.h:52:35: note: in expansion of macro ‘MP_CLIENT_RXQ_NAME’ 52 | snprintf(buffer, sizeof(buffer), MP_CLIENT_RXQ_NAME, id); | ^~~~~~~~~~~~~~~~~~ This is a false positive, as the value of the "id" is limited to 255, being stored in the app as a uint8_t value, removing the possibility of the %u being replaced by anything other then 3 characters max (rather than up to 10 as thought by the compiler). Therefore, the warning can be easily removed by changing the type of the "id" parameter to the local function from "unsigned" to "uint8_t" also, ensuring the compiler is aware of the range limit.
