Please apply the following patch for smc to netdev's net tree. Both patches fix possible out-of-bounds reads. The original code expected that snprintf() reads len-1 bytes from source and appends the terminating null, but actually snprintf() first copies len bytes and finally overwrites the last byte with a null. Fix this by using memcpy() and terminating the string afterwards.
