from optee_os.

I'm not aware of this error upstream.
Have you made any changes to the source code?

from optee_os.

@jenswi-linaro nothing change in this version , same code run in different type soc , one is ok , one is wrong

from optee_os.

Do you mean that git describe gives 3.8.0?

from optee_os.

@jenswi-linaro this branch is our internal branch name , but the source code copy form the optee upstream about 2 years ago .
may be the latest tee has fixed this issue . but it is not the best way to fix this bug .

do you have any guide about this issue ?Where should I do a memory check to prevent memory stampede ？

@jenswi-linaro how to avoid write beyond the size of an allocated buffer?

from optee_os.

I'm sorry, but I can debug your code. The problematic buffer was allocated in mobj_phys_alloc(). I can't tell whether this is an upstream bug or if it has been fixed upstream.
