Comparing the initial PN value with the new value will allow the user to update the SA using the initial PN value as a parameter like this: $ ip macsec add macsec0 tx sa 0 pn 1 on key 00 \ ead3664f508eb06c40ac7104cdae4ce5 $ ip macsec set macsec0 tx sa 0 pn 1 off Fixes: 8ff0ac5be144 ("net/mlx5: Add MACsec offload Tx command support") Fixes: aae3454e4d4c ("net/mlx5e: Add MACsec offload Rx command support") Signed-off-by: Radu Pirea (NXP OSS) <radu-nicolae.pirea@....nxp.com> --- Changes in v7: - none Changes in v6: - patch added in v6 drivers/net/ethernet/mellanox/mlx5/core/en_accel/macsec.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/drivers/net/ethernet/mellanox/mlx5/core/en_accel/macsec.c b/drivers/net/ethernet/mellanox/mlx5/core/en_accel/macsec.c index c9c1db971652..d4ebd8743114 100644 --- a/drivers/net/ethernet/mellanox/mlx5/core/en_accel/macsec.c +++ b/drivers/net/ethernet/mellanox/mlx5/core/en_accel/macsec.c @@ -580,7 +580,7 @@ static int mlx5e_macsec_upd_txsa(struct macsec_context *ctx) goto out; } - if (tx_sa->next_pn != ctx_tx_sa->next_pn_halves.lower) { + if (ctx->sa.update_pn) { netdev_err(netdev, "MACsec offload: update TX sa %d PN isn't supported\n", assoc_num); err = -EINVAL; @@ -973,7 +973,7 @@ static int mlx5e_macsec_upd_rxsa(struct macsec_context *ctx) goto out; } - if (rx_sa->next_pn != ctx_rx_sa->next_pn_halves.lower) { + if (ctx->sa.update_pn) { netdev_err(ctx->netdev, "MACsec offload update RX sa %d PN isn't supported\n", assoc_num); -- 2.34.1
