Subject: patch 'build: hide local symbols in shared libraries' has been queued to stable release 21.11.1
Date: Thu, 10 Mar 2022 12:11:26 +0000 [thread overview]
Message-ID: <20220310121127.1324802-20-ktraynor@redhat.com> (raw)
In-Reply-To: <20220310121127.1324802-1-ktraynor@redhat.com>
Hi,
FYI, your patch has been queued to stable release 21.11.1
Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 03/14/22. 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/026470bafaa02cba0d46ed7b7e835262399a009a
Thanks.
Kevin

Subject: [PATCH] build: hide local symbols in shared libraries
[ upstream commit b403498e14229ee903c8fff9baefcb72894062f3 ]
The symbols which are not listed in the version script
are exported by default.
Adding a local section with a wildcard make non-listed functions
and variables as hidden, as it should be in all version.map files.
These are the changes done in the shared libraries:
- DF .text Base auxiliary_add_device
- DF .text Base auxiliary_dev_exists
- DF .text Base auxiliary_dev_iterate
- DF .text Base auxiliary_insert_device
- DF .text Base auxiliary_is_ignored_device
- DF .text Base auxiliary_match
- DF .text Base auxiliary_on_scan
- DF .text Base auxiliary_scan
- DO .bss Base auxiliary_bus_logtype
- DO .data Base auxiliary_bus
- DO .bss Base gpu_logtype
There is no impact on regexdev library.
Because these local symbols were exported as non-internal
in DPDK 21.11, any change in these functions would break the ABI.
Exception rules are added for these experimental libraries,
so the ABI check will skip them until the next ABI version.
A check is added to avoid such miss in future.
Fixes: 1afce3086cf4 ("bus/auxiliary: introduce auxiliary bus")
Fixes: 8b8036a66e3d ("gpudev: introduce GPU device class library")
