The strnlen_user function takes two arguments: the user space buffer address and the maximum length to check.
strnlen_user函数带有两个参数：用户空间缓冲区地址和要检查的最大长度。
The strncpy_from_user function copies a string from user space into a kernel buffer, given a user space source address and Max length.
strncpy _ from_user函数将一个字符串从用户空间复制到一个内核缓冲区，给定一个用户空间源地址和最大长度。
The strnlen_user function is used just like strnlen but assumes that the buffer is available in user space.
strnlen_user函数也能像strnlen 那样使用，但前提是缓冲区在用户空间可用。

EDIT调用外部编辑器，将SQLBufferUtility内容加载进去，然后用户可以修改该内容并将其保存回缓冲区。
This function will create a new buffer feature data layer around the input point features at user specified distance.
此函数将以输入点为基础，按照用户指定的距离创建一个新缓冲区轮廓数据层。
The buffer address is actually a user-space buffer, so you won't be able to read it directly.
缓冲区地址实际上是一个用户空间的缓冲区，因此我们不能直接读取它。
They declared the likelihood was very low that user input could be successfully manipulated to reach a vulnerable buffer in such a way as to cause a security violation.
他们声明能够成功操纵使用者输入到达易受攻击的缓冲区从而造成安全性破坏的可能性已非常小了。
If a malicious user can overwrite the buffer, then the value of the flag can be changed, thus providing the attacker with illegal access to private files.
如果有不怀好意的使用者覆写缓冲区，则会变更标志的值，从而指出攻击者是非法存取专用文件。
Now the data is stored in the user address space buffer, and it can begin its way down again.
现在数据被储存在用户地址空间缓冲区。
It would be better to read a line into a temporary buffer and then copy this to user space in one go.
比较好的方法是读取一行到临时缓冲区，然后将这一行一次性拷贝到用户空间。
Listing 1 does not validate user-supplied data when copying it to the buffer member of the previously allocated struct mystruct using the strcpy function, resulting in a heap-based buffer overflow.
