Hi,

FYI, your patch has been queued to stable release 21.11.2

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 05/15/22. 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/804b2e64eb2f09c46e2521271ac3735624512e86

Thanks.

Kevin

Subject: [PATCH] mem: skip attaching external memory in secondary process

[ upstream commit 90bf3f89ed33f78e9f41818caf123e13e508dee7 ]

Currently, EAL init in secondary processes will attach all fbarrays
in the memconfig to have access to the primary process's page tables.
However, fbarrays corresponding to external memory segments should
not be attached at initialization, because this will happen as part
of `rte_extmem_attach` [1] or `rte_malloc_heap_memory_attach` [2] calls.

1: https://doc.dpdk.org/api/rte__memory_8h.html#a2796da68de6825f8edf53759f8e4d230
2: https://doc.dpdk.org/api/rte__malloc_8h.html#af6360dea35bdf162feeb2b62cf149fd3

Fixes: ff3619d6244b ("malloc: allow attaching to external memory chunks")
