|
||||
|
||||
Fix the cmdline parsing of the "blkdevparts=" parameter using strsep(),
|
||||
which makes the code simpler.
|
||||
|
||||
Before commit 146afeb235cc ("block: use strscpy() to instead of
|
||||
strncpy()"), we used a strncpy() to copy a block device name and partition
|
||||
names. The commit simply replaced a strncpy() and NULL termination with
|
||||
a strscpy(). It did not update calculations of length passed to strscpy().
|
||||
While the length passed to strncpy() is just a length of valid characters
|
||||
without NULL termination ('\0'), strscpy() takes it as a length of the
|
||||
destination buffer, including a NULL termination.
|
||||
|
||||
Since the source buffer is not necessarily NULL terminated, the current
|
||||
code copies "length - 1" characters and puts a NULL character in the
|
||||
destination buffer. It replaces the last character with NULL and breaks
|
||||
the parsing.
|
||||
|
||||
As an example, that buffer will be passed to parse_parts() and breaks
|
||||
parsing sub-partitions due to the missing ')' at the end, like the
|
||||
following.
|
||||
|
||||
example (Check Point V-80 & OpenWrt):

2. strscpy() returns -E2BIG and the destination buffer has

|

3. "48M@10M(kernel-1\0" is passed to parse_subpart()
|

|
||||
|
||||
By the way, strscpy() takes a length of destination buffer and it is
|
||||
often confusing when copying characters with a specified length. Using
|
||||
strsep() helps to separate the string by the specified character. Then,
|
||||
we can use strscpy() naturally with the size of the destination buffer.
|
||||
|
||||
Separating the string on the fly is also useful to omit the redundant
|
||||
string copy, reducing memory usage and improve the code readability.
|
||||
|
||||
