Thorsten Blum de17000b40 smb: server: Fix extension string in ksmbd_extract_shortname() ... commit 8e7d178d06 upstream. In ksmbd_extract_shortname(), strscpy() is incorrectly called with the length of the source string (excluding the NUL terminator) rather than the size of the destination buffer. This results in "__" being copied to 'extension' rather than "___" (two underscores instead of three). Use the destination buffer size instead to ensure that the string "___" (three underscores) is copied correctly.
