Hello, this is the v3 of the packed-struct-passed-on-stack series. This revision follows on Ihor's comments on v2. Signed-off-by: Alexis Lothoré (eBPF Foundation) <alexis.lothore@xxxxxxxxxxx> --- Changes in v3: - add uncertain param loc logic to saved_functions_combine to deduplicate functions - remove unneeded call to class__infer_holes - bring a userspace binary instead of a OoT kernel module for testing - consolidate paths used in the new test - Link to v2: https://lore.kernel.org/r/20250703-btf_skip_structs_on_stack-v2-0-4767e3ba10c9@xxxxxxxxxxx Changes in v2: - infer structs attributes - skip function encoded if some consumed struct (passed on stack) is marked as packed - add some tests in btf_functions.sh - drop RFC prefix - Link to v1: https://lore.kernel.org/r/20250618-btf_skip_structs_on_stack-v1-1-e70be639cc53@xxxxxxxxxxx --- Alexis Lothoré (eBPF Foundation) (3): btf_encoder: skip functions consuming packed structs passed by value on stack tests: add some tests validating skipped functions due to uncertain arg location gitignore: ignore all the test kmod build-related files .gitignore | 3 ++ btf_encoder.c | 53 +++++++++++++++++++++++++++-- dwarves.h | 1 + tests/bin/Makefile | 10 ++++++ tests/bin/test_bin.c | 66 ++++++++++++++++++++++++++++++++++++ tests/btf_functions.sh | 91 ++++++++++++++++++++++++++++++++++++++++++++++++++ 6 files changed, 221 insertions(+), 3 deletions(-) --- base-commit: 042d73962d35fdd1466e056f1ea14590b1cdbb9b change-id: 20250617-btf_skip_structs_on_stack-006adf457d50 Best regards, -- Alexis Lothoré, Bootlin Embedded Linux and Kernel engineering https://bootlin.com
