If anyone has any objections, please let me know. ------------------ From: Simon Horman [ Upstream commit 91d516d4de48532d967a77967834e00c8c53dfe6 ] Increase size of queue_name buffer from 30 to 31 to accommodate the largest string written to it. This avoids truncation in the possibly unlikely case where the string is name is the maximum size. Flagged by gcc-14: .../mvpp2_main.c: In function 'mvpp2_probe': .../mvpp2_main.c:7636:32: warning: 'snprintf' output may be truncated before the last format character [-Wformat-truncation=] 7636 | "stats-wq-%s%s", netdev_name(priv->port_list[0]->dev), | ^ .../mvpp2_main.c:7635:9: note: 'snprintf' output between 10 and 31 bytes into a destination of size 30 7635 | snprintf(priv->queue_name, sizeof(priv->queue_name), | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 7636 | "stats-wq-%s%s", netdev_name(priv->port_list[0]->dev), | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 7637 | priv->port_count > 1 ? "+" : ""); | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Introduced by commit 118d6298f6f0 ("net: mvpp2: add ethtool GOP statistics"). I am not flagging this as a bug as I am not aware that it is one. Compile tested only.
