Guvenc Gulce 8a44653689 net/smc: use memcpy instead of snprintf to avoid out of bounds read
Using snprintf() to convert not null-terminated strings to null
terminated strings may cause out of bounds read in the source string.
Therefore use memcpy() and terminate the target string with a null
afterwards.
