Hello:

This patch was applied to netdev/net-next.git (main)
by Jakub Kicinski [off-list ref]:

The `strcpy()` function is deprecated and moving towards code-tree
elimination. Replacing it with `strscpy()` fixes potential buffer
overflow vectors by ensuring safe NULL-termination based on the
destination buffer size limit [1][2].

To make the interface safer and more robust for future callers, refactor
`tipc_bearer_get_name()` to accept a destination buffer length parameter.
Replace `strcpy()` with `strscpy()` and pass through any potential
`-E2BIG` truncation error code up to the caller. Update the existing
caller in `net/tipc/monitor.c` to pass its array size.
