Subject: [PATCH v2 net-next 0/2] update NULL pointer handling in generated code
Date: Fri, 7 Aug 2026 17:14:58 +0000 [thread overview]
Message-ID: <20260807171500.7188-1-thaisonphan@google.com> (raw)
This series fixes potential NULL pointer dereferences in YNL-generated C
code during dump list freeing and memory allocation in parsing getters.
Changes in v2:
- Moved null check in dump list free to be separate from while loop
- Updated allocation checks to only be for getters as setters will
be handled in a separate patch.
Testing:
- Regenerated all c headers/sources under tools/net/ynl/generated/
- Built libynl, ynltool, and test binaries without errors or warnings
- Ran make target run_tests in tools/net/ynl/tests successfully
- Ran tools/testing/selftests/drivers/net/psp.py in QEMU x86_64
successfully
v1:
