This patch series builds on the allocation function attributes added in 24.11 release. These annotations will allow for compiler to flag cases where a pointer is allocated with one function but incorrectly passed to a different free function.
The current code base does this correctly now, but adding attributes will catch future bugs, or errors in user programs. For each of these patches, the free function prototype needs to be reordered to be before the function attribute of the allocator. Checkpatch perl script falsely complains in a couple patches because it doesn't really understand C syntax for attributes. v2 - fix issue with bitratestats prototypes Stephen Hemminger (15): fib: add allocation function attributes rib: annotate rib allocation functions hash: add allocation function attributes lpm: add allocation function attributes pipeline: add allocation function attributes acl: add allocation function attributes bitratestats: add allocation function attributes member: add allocation function attributes mempool: add allocation function attributes eventdev: add allocation function attributes ring: add allocation function attributes reorder: add allocation function attributes compressdev: add allocation function attributes telemetry: add allocation function attributes sched: add allocation function attributes lib/acl/rte_acl.h | 26 ++++++++------- lib/bitratestats/rte_bitrate.h | 4 +-- lib/compressdev/rte_comp.h | 28 ++++++++-------- lib/eventdev/rte_event_ring.h | 27 +++++++-------- lib/fib/rte_fib.h | 26 ++++++++------- lib/fib/rte_fib6.h | 24 +++++++------- lib/fib/trie.h | 7 ++-- lib/hash/rte_fbk_hash.h | 24 +++++++------- lib/hash/rte_hash.h | 21 ++++++------ lib/lpm/rte_lpm.h | 23 ++++++------- lib/lpm/rte_lpm6.h | 23 ++++++------- lib/member/rte_member.h | 24 +++++++------- lib/mempool/rte_mempool.h | 37 +++++++++++---------- lib/pipeline/rte_port_in_action.h | 55 ++++++++++++++++--------------- lib/pipeline/rte_table_action.h | 53 +++++++++++++++-------------- lib/reorder/rte_reorder.h | 23 ++++++------- lib/rib/rte_rib.h | 24 +++++++------- lib/rib/rte_rib6.h | 24 +++++++------- lib/ring/rte_ring.h | 22 +++++++------ lib/sched/rte_sched.h | 23 +++++++------ lib/telemetry/rte_telemetry.h | 21 ++++++------ 21 files changed, 288 insertions(+), 251 deletions(-) -- 2.45.2
