In contrast to the core network refcounter conversions that were merged earlier, these are much more straightforward ones. This series, for various networking drivers, replaces atomic_t reference counters with the new refcount_t type and API (see include/linux/refcount.h). By doing this we prevent intentional or accidental underflows or overflows that can led to use-after-free vulnerabilities. The patches are fully independent and can be cherry-picked separately. Patches are based on top of net-next. If there are no objections to the patches, please merge them via respective trees Elena Reshetova (15): drivers, net, ethernet: convert clip_entry.refcnt from atomic_t to refcount_t drivers, net, ethernet: convert mtk_eth.dma_refcnt from atomic_t to refcount_t drivers, net, mlx4: convert mlx4_cq.refcount from atomic_t to refcount_t drivers, net, mlx4: convert mlx4_qp.refcount from atomic_t to refcount_t drivers, net, mlx4: convert mlx4_srq.refcount from atomic_t to refcount_t drivers, net, mlx5: convert mlx5_cq.refcount from atomic_t to refcount_t drivers, net, mlx5: convert fs_node.refcount from atomic_t to refcount_t drivers, net, hamradio: convert sixpack.refcnt from atomic_t to refcount_t drivers, net: convert masces_rx_sa.refcnt from atomic_t to refcount_t drivers, net: convert masces_rx_sc.refcnt from atomic_t to refcount_t drivers, net: convert masces_tx_sa.refcnt from atomic_t to refcount_t drivers, net, ppp: convert asyncppp.refcnt from atomic_t to refcount_t drivers, net, ppp: convert ppp_file.refcnt from atomic_t to refcount_t drivers, net, ppp: convert syncppp.refcnt from atomic_t to refcount_t drivers, connector: convert cn_callback_entry.refcnt from atomic_t to refcount_t drivers/connector/cn_queue.c | 4 ++-- drivers/connector/connector.c | 2 +- drivers/net/ethernet/chelsio/cxgb4/clip_tbl.c | 13 +++++------ drivers/net/ethernet/chelsio/cxgb4/clip_tbl.h | 4 +++- drivers/net/ethernet/mediatek/mtk_eth_soc.c | 8 ++++--- drivers/net/ethernet/mediatek/mtk_eth_soc.h | 4 +++- drivers/net/ethernet/mellanox/mlx4/cq.c | 8 +++---- drivers/net/ethernet/mellanox/mlx4/qp.c | 8 +++---- drivers/net/ethernet/mellanox/mlx4/srq.c | 8 +++---- drivers/net/ethernet/mellanox/mlx5/core/cq.c | 16 ++++++------- drivers/net/ethernet/mellanox/mlx5/core/fs_core.c | 28 +++++++++++------------ drivers/net/ethernet/mellanox/mlx5/core/fs_core.h | 3 ++- drivers/net/hamradio/6pack.c | 12 +++++----- drivers/net/macsec.c | 25 ++++++++++---------- drivers/net/ppp/ppp_async.c | 10 ++++---- drivers/net/ppp/ppp_generic.c | 21 +++++++++-------- drivers/net/ppp/ppp_synctty.c | 11 +++++---- include/linux/connector.h | 4 ++-- include/linux/mlx4/device.h | 8 +++---- include/linux/mlx5/cq.h | 4 ++-- 20 files changed, 105 insertions(+), 96 deletions(-) -- 2.7.4
