ld exports any global symbol by default if no version script is passed.
As a consequence, the incriminated change let any public symbol leak
out of the driver shared libraries.

Hide again those symbols by providing a default map file which
unexports any global symbol using a local: * catchall statement.

The check on symbols is skipped for this default map file as it is
intentionnally an empty map (see commit b67bdda86cd4 ("devtools: catch
empty symbol maps")) and there is nothing to check in it.

While at it, move Windows specific objects where needed for better
readability.

I assume this will cause warnings for ABI check scripts, how can we

How it is skipped, './devtools/check-symbol-maps.sh' still complains

Indeed.

Some options:
- add exhaustive suppression rules in devtools/libabigail.abignore,
- retag the v22.11 release with this fix, but we already announced it
and people started downloading the tarball,
- release a .1 version and compare ABI against it (either in the main
repo, or in the 22.11 stable branch, through for the ABI check in GHA,
it would be simpler to have the tag in the main repo..),

Do you have other ideas?

I had considered the call check-symbols.sh during build.
But it is true that if you call check-symbol-maps.sh alone, we will
get a warning.

I will exclude it in v2.

UNH Windows tests look fine.

(let's forget about my concern on GHA, we have the REF_GIT_REPO param,
so we can point at the dpdk-stable repo, and go with a "normal"
release in 22.11 stable branch)

OK to have v22.11.1 stable release with this fix.

As a consequence, the incriminated change let any public symbol leak
out of the driver shared libraries.

Hide again those symbols by providing a default map file which
unexports any global symbol using a local: * catch-all statement.

The checks are skipped for this default map file as it is intentionnally
an empty map (see commit b67bdda86cd4 ("devtools: catch empty symbol
maps")) and there is nothing else to check in this map.

While at it, move Windows specific objects where needed for better

Tested v2, looks good.

Additionnally, Luca, could you describe how you caught the issue?
Could we enhance the CI to catch this earlier?

ld exports any global symbol by default if no version script is passed.
As a consequence, the incriminated change let any public symbol leak
out of the driver shared libraries.

Hide again those symbols by providing a default map file which
unexports any global symbol using a local: * catch-all statement.

The checks are skipped for this default map file as it is intentionnally
an empty map (see commit b67bdda86cd4 ("devtools: catch empty symbol
maps")) and there is nothing else to check in this map.

Fixes: 7dde9c844a37 ("drivers: omit symbol map when unneeded")

Thanks Bruce.

I prefer to separate the "cosmetic" part around Windows (and fix
lib/meson.build too), so I sent a v3 series with only the first patch
marked as backport.

Technically, for this patch the lk_deps assignment does not need to be
split into two, but it does make the second patch smaller, so I'm ok to
keep this as you have in this version.

just for awareness the default is the opposite on windows symbols are
private by default and have to be explicitly made public.

also, for gcc we could go to the extreme and pass -fvisibility=hidden
and fix out any other symbols that are missed.

if you're really going wild you may consider introducing a macro that
can be expanded to __attribute__((visibility("default"))) combined with
-fvisibility=hidden (as opposed to version.map) the main benefit being
there's only a single source of truth about whether or not the symbol is
public, you don't have to look in 2 places.
(anyway, probably not a popular idea...)

Yes, otherwise, I would have kept it untouched.

ld exports any global symbol by default if no version script is passed.
As a consequence, the incriminated change let any public symbol leak
out of the driver shared libraries.

Hide again those symbols by providing a default map file which
unexports any global symbol using a local: * catch-all statement.

The checks are skipped for this default map file as it is intentionnally
an empty map (see commit b67bdda86cd4 ("devtools: catch empty symbol
maps")) and there is nothing else to check in this map.

This change impacts the exported symbols, hence, bump the version in the
ABI check to the v22.11.1 from the 22.11 LTS branch.

Fixes: 7dde9c844a37 ("drivers: omit symbol map when unneeded")

Series applied.

Please, maintainers and CI teams, when you enable ABI checks in the
main branch, or in the 22.11 LTS branch, use the dpdk-stable 22.11.1
tag as a reference.
Thanks.

Should we also add a tag on main repo, as new development does not happen
on stable tree?

You can fetch the v22.11.1 tag from the stable tree.

Yes, that is an obvious option.
But adding a tag on same repo is more convenient from developer point of view. 
However, it is my personal view, others may differ.

From developer point of view, you should use devtools/test-meson-builds.sh
which does the "git clone" for you.

This is what I have in ~/.config/dpdk/devel.config
export DPDK_ABI_REF_DIR=$root/dpdk-build/abiref
export DPDK_ABI_REF_VERSION=v22.11.1

Does it help to update 'test-meson-builds.sh' to use an environment
variable to select which repo to clone?
If so, I can send a patch for it.

I was wondering too...
I would expect most maintainers have the stable repo in their config
but it would not hurt to handle the case when they don't for others.

Hello,

Community Lab team members are wondering whether it is possible to bump
v22.11 to include at least this patch. We have an existing codebase which
relies on a vXX.XX scheme for producing ABI references. We parse that out
at different places in our code, so fixing this to handle vXX.XX.X will
require some changes on our end. We can do that, but it puts the timeline
on turning on ABI testing at the community lab back some. A v22.11 tagged
release with this patch would allow for us to turn on ABI testing
immediately. There was also a suggestion that having the "base" tag (like
the simple v22.11) point to the latest revision is a more standard version
naming approach and may be more intuitive than what is being used currently.

If that is not possible, we will update our code to be able to refer to a
vXX.XX.X tag for producing the ABI reference. If we adopt this approach, we
would like to request that with future releases, a "vXX.XX.0" tag could
always be made available for us to produce ABI references from. That way,
we can prepare for turning on ABI testing knowing beforehand the tag name
we will be using.

I'm sorry Patrick that it gives you more work.
Your proposals below don't look possible because a tag is something fixed forever.
We had an ABI issue in the initial tag so we cannot use the tag v22.11 as planned.
I don't see how we can better plan except having more tests on release candidates.

Thomas - thanks for the response. We will proceed with making the necessary
changes for using v22.11.1.
