Technical task
Major Description
In osd_scrub_setup(), id variable is of type 'struct osd_inode_id *' (size 8). But then this variable is passed to __osd_oi_lookup(), and in this function, it is passed to osd_oi_iam_lookup(), which casts it to a 'struct dt_rec *'. Then it is passed to osd_fid_unpack() by casting it to 'struct lu_fid *'. And at last, inside this function, a memcpy() is performed considering the variable is of type 'struct lu_fid *', which is of size 16.
So we are accessing memory beyond what was allocated for that variable.
I do not know how to fix this issue, as it is quite complex.
