Hello: This patch was applied to netdev/net-next.git (main) by Jakub Kicinski [off-list ref]: On Wed, 26 Nov 2025 23:08:05 +0100 you wrote:
strncpy() is deprecated [1] for NUL-terminated destination buffers because it does not guarantee NUL termination. Replace it with strscpy() to ensure the destination buffer is always NUL-terminated and to avoid any additional NUL padding. Although the identifier buffer has 252 usable bytes, strncpy() copied only up to 251 bytes to the zero-initialized buffer, relying on the last byte to act as an implicit NUL terminator. Switching to strscpy() avoids this implicit behavior and does not use magic numbers. [...]
Here is the summary with links:
