[dpdk-stable] patch 'bus/dpaa: fix build with musl' has been queued to stable release 20.11.2

[Xueming Li]

Hi,

FYI, your patch has been queued to stable release 20.11.2

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 05/12/21. 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/steevenlee/dpdk

This queued commit can be viewed at:
https://github.com/steevenlee/dpdk/commit/fc4664ada56f15a73045f6222247522c17d3a53f

Thanks.

Subject: [PATCH] bus/dpaa: fix build with musl
Cc: Luca Boccassi <bluca at debian.org>

[ upstream commit e9fd4b87f08d4da01ea9bde075f02e702b65a784 ]

The header files argp.h and error.h do not exist in musl libc.

Fix build with musl libc by using err(3) instead of
the GNU-specific error(3).

We could have used the identical errx("...: %s", strerror(ret))` but
strerror(3) is not thread-safe and the strerror_r variant has two
incompatible versions, one GNU specific and one XSI-compliant.
Avoid the mess by letting "err" use the thread-local errno.

This also fixes error message for kzmalloc failures which previously
would always have given "Unknown error -1", since that is what
strerror(-1) returns. Let "err" use the proper error message from errno
which is set by kzalloc.

Fixes: 9d32ef0f5d61 ("bus/dpaa: support creating dynamic HW portal")
Fixes: f09ede6c8fd1 ("bus/dpaa: add BMAN driver core")
Fixes: 5b22cf744689 ("bus/dpaa: introducing FMan configurations")
Fixes: 39f373cf015a ("bus/dpaa: add compatibility and helper macros")
