There are one set of i40e and iavf warnings I couldn't figure out how to fix because the driver is already using vsnprintf without an explicit "const char *" format string. Tested with both gcc-12 and clang-15. I found gcc-12 runs clean after this series but clang-15 is a little worried about the vsnprintf lines. summary of warnings: drivers/net/ethernet/intel/fm10k/fm10k_ethtool.c:148:34: warning: format string is not a string literal [-Wformat-nonliteral] drivers/net/ethernet/intel/ixgbe/ixgbe_ethtool.c:1416:24: warning: format string is not a string literal (potentially insecure) [-Wformat-security] drivers/net/ethernet/intel/ixgbe/ixgbe_ethtool.c:1416:24: note: treat the string as an argument to avoid this drivers/net/ethernet/intel/ixgbe/ixgbe_ethtool.c:1421:6: warning: format string is not a string literal (potentially insecure) [-Wformat-security] drivers/net/ethernet/intel/ixgbe/ixgbe_ethtool.c:1421:6: note: treat the string as an argument to avoid this drivers/net/ethernet/intel/igc/igc_ethtool.c:776:24: warning: format string is not a string literal (potentially insecure) [-Wformat-security] drivers/net/ethernet/intel/igc/igc_ethtool.c:776:24: note: treat the string as an argument to avoid this drivers/net/ethernet/intel/igc/igc_ethtool.c:779:6: warning: format string is not a string literal (potentially insecure) [-Wformat-security] drivers/net/ethernet/intel/igc/igc_ethtool.c:779:6: note: treat the string as an argument to avoid this drivers/net/ethernet/intel/iavf/iavf_ethtool.c:199:34: warning: format string is not a string literal [-Wformat-nonliteral] drivers/net/ethernet/intel/igb/igb_ethtool.c:2360:6: warning: format string is not a string literal (potentially insecure) [-Wformat-security] drivers/net/ethernet/intel/igb/igb_ethtool.c:2360:6: note: treat the string as an argument to avoid this drivers/net/ethernet/intel/igb/igb_ethtool.c:2363:6: warning: format string is not a string literal (potentially insecure) [-Wformat-security] drivers/net/ethernet/intel/igb/igb_ethtool.c:2363:6: note: treat the string as an argument to avoid this drivers/net/ethernet/intel/i40e/i40e_ethtool.c:208:34: warning: format string is not a string literal [-Wformat-nonliteral] drivers/net/ethernet/intel/i40e/i40e_ethtool.c:2515:23: warning: format string is not a string literal (potentially insecure) [-Wformat-security] drivers/net/ethernet/intel/i40e/i40e_ethtool.c:2515:23: note: treat the string as an argument to avoid this drivers/net/ethernet/intel/i40e/i40e_ethtool.c:2519:23: warning: format string is not a string literal (potentially insecure) [-Wformat-security] drivers/net/ethernet/intel/i40e/i40e_ethtool.c:2519:23: note: treat the string as an argument to avoid this drivers/net/ethernet/intel/ice/ice_ethtool.c:1064:6: warning: format string is not a string literal (potentially insecure) [-Wformat-security] drivers/net/ethernet/intel/ice/ice_ethtool.c:1064:6: note: treat the string as an argument to avoid this drivers/net/ethernet/intel/ice/ice_ethtool.c:1084:6: warning: format string is not a string literal (potentially insecure) [-Wformat-security] drivers/net/ethernet/intel/ice/ice_ethtool.c:1084:6: note: treat the string as an argument to avoid this drivers/net/ethernet/intel/ice/ice_ethtool.c:1100:24: warning: format string is not a string literal (potentially insecure) [-Wformat-security] drivers/net/ethernet/intel/ice/ice_ethtool.c:1100:24: note: treat the string as an argument to avoid this Suggested-by: Alexander Lobakin Reviewed-by: Przemek Kitszel Signed-off-by: Jesse Brandeburg Tested-by: Pucha Himasekhar Reddy (A Contingent worker at Intel) Signed-off-by: Jacob Keller --- drivers/net/ethernet/intel/i40e/i40e_ethtool.c | 6 ++++-- drivers/net/ethernet/intel/iavf/iavf_ethtool.c | 8 +++----- drivers/net/ethernet/intel/ice/ice_ethtool.c | 7 ++++--- drivers/net/ethernet/intel/igb/igb_ethtool.c | 4 ++-- drivers/net/ethernet/intel/igc/igc_ethtool.c | 5 +++-- drivers/net/ethernet/intel/ixgbe/ixgbe_ethtool.c | 4 ++-- 6 files changed, 18 insertions(+), 16 deletions(-) diff --git a/drivers/net/ethernet/intel/i40e/i40e_ethtool.c b/drivers/net/ethernet/intel/i40e/i40e_ethtool.c index ebf36f76c0d7..fd7163128c4d 100644 --- a/drivers/net/ethernet/intel/i40e/i40e_ethtool.c +++ b/drivers/net/ethernet/intel/i40e/i40e_ethtool.c @@ -2514,11 +2514,13 @@ static void i40e_get_priv_flag_strings(struct net_device *netdev, u8 *data) u8 *p = data;
