Module copies a user supplied string (module parameter) into a buffer using strncpy() and does not check that the buffer is null terminated.
Replace call to strncpy() with call to strlcpy() ensuring that the buffer is null terminated. Replace magic number with pre-existing compile time constant. Check return value of call to strlcpy() and throw warning if source string is truncated. v1 was a single patch. v2 adds 2 extra patches while retaining the original v1 patch as the first of the series. v2: - Replace magic number - Check return value of call to strlcpy() Tobin C.
