[PATCH v2 net-next 0/2] update NULL pointer handling in generated code

Posted by Thaison Phan 1 month, 3 weeks ago

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:
https://lore.kernel.org/netdev/20260803201652.2752685-1-thaisonphan@google.com/
