Subject: Possible error in debugfs/file.c
Date: Wed, 3 Dec 2014 03:13:28 +1100 [thread overview]
Message-ID: <20141202161328.GA15584@arch> (raw)
I'm just reading the kernel source and came across this which doesn't look quite right to me:
616 size_t size = strlen(file->private_data);
strlen is used here when the pointer points to type:
567 struct array_data {
568 void *array;
569 u32 elements;
570 };
I think line 616 should probably be something like:
size_t size = file->private_data.elements*sizeof(u32);
I think strlen would terminate incorrectly on any null byte, and is unnecessary
since the data is already counted.
Is this a legitimate criticism?
