[dpdk-dev] [PATCH] common/mlx5: fix missing __rte_internal tags in exported functions

[dpdk-dev] [PATCH] common/mlx5: fix missing __rte_internal tags in exported functions

[Tal Shnaiderman]

Several functions introduced in the addition of the Windows support to
mlx5 were missing the __rte_internal tag although being exported.

Fixes: 1552fb287166 ("common/mlx5: add alloc/dealloc PD on Windows")
Fixes: 1969ee424405 ("common/mlx5: add UMEM reg/dereg functions on Windows")
Fixes: ba420719823c ("common/mlx5: add reg/dereg MR on Windows")

Removing __ makes it wrong: rte_internal does not exist.
The idea of discouraging the use of underscore is to avoid
naming bits and bytes in the title.
Here it should be: "add missing internal tags to some functions"

My suggestion was to make it like this:
"fix missing rte internal tags in exported functions"

But, I find your suggestion even better, so I'd change it to that

Can we merge this directly to main repo?
Since debug build is broken without it.

Which debug option?
It is broken since when?

"meson --buildtype=debug build && ninja -C build" is broken [1], I thought that 
is why this patch is done at first place.
Some checks are done now only in the debug mode, since checks are reduced to 
developer mode [2].

It become visible when .def file removed [3], since that is when symbols are 
added to the .map file.

I don't think [2] has something to do with it.

The symbols fixed here are inlined.
In release (and debugoptimized) modes, I can see no trace of them in the .o

$ nm build/drivers/librte_common_mlx5.a |grep umem_reg
                 U mlx5dv_devx_umem_reg
0000000000000410 t mlx5_glue_devx_umem_reg

While in debug mode:
$ nm build.debug/drivers/librte_common_mlx5.a |grep umem_reg
00000000000000b9 t mlx5_os_umem_reg
                 ^^^^^^^^^^^^^^^^^^
                 U mlx5dv_devx_umem_reg
0000000000001578 t mlx5_glue_devx_umem_reg


The symbol check then catches mlx5_os_umem_reg wrt the version.map and
complains mlx5_os_umem_reg is not tagged internal.

Right, the issue was in observed from commit 56ea803e878e ("build: remove Windows export symbol list") and this patch fixes it, apologies for not stating it in the commit log.

Since rte_common_mlx5_exports.def was merged to version.map several functions which needed export only for Windows were brought in, e.g. mlx5_os_umem_reg, in Linux it is implemented in the .h file but has a .c implementation on Windows so it is needed to be in version.map.

Windows doesn't run symbol check in debug so up until the file merge it wasn't caught.

Got it, if so this is not related to [2] as you said, but related to the debug 
mode build, thanks for clarification.

It is fixing Linux debug build (note: should be added to CI).

Applied in main tree with this message, thanks:

common/mlx5: add missing internal tags

Several functions introduced in the addition of the Windows support
to mlx5 were missing the __rte_internal tag.
This miss is better revealed when symbols became exported on Linux too,
and it is caught by the symbol checker with --buildtype=debug.

Fixes: 1552fb287166 ("common/mlx5: add alloc/dealloc PD on Windows")
Fixes: 1969ee424405 ("common/mlx5: add UMEM reg/dereg functions on Windows")
Fixes: ba420719823c ("common/mlx5: add reg/dereg MR on Windows")
Fixes: 56ea803e878e ("build: remove Windows export symbol list")
