It will be pushed if I get no objections before 11/01/22. 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 This queued commit can be viewed at: https://github.com/kevintraynor/dpdk-stable/commit/5f22fcf619e79e772eae919af0d7eb2b325e4d28 Thanks. Kevin --- >From 5f22fcf619e79e772eae919af0d7eb2b325e4d28 Mon Sep 17 00:00:00 2001 From: Fidaullah Noonari Date: Thu, 28 Jul 2022 14:41:03 +0500 Subject: [PATCH] malloc: fix storage size for some allocations [ upstream commit f92b9ebed03dbd140a5a7b921cb898e661a59068 ] The amount of memory to allocate from the system for heap expansion was calculated in a way that may yield one page more than needed. This could hit the allocation limit from the system or EAL. The allocation would fail despite enough memory being available.
