Read() should not write anything when returning 0 (EOF). This patch does not correct the same bug occuring for : nbr_read=read(file, buf, nbytes) When nbr_read<nbytes, nbytes bytes are copied into the virtual RAM instead of nbr_read. If buf is smaller than nbytes, a page fault occurs, even if buf is in fact bigger than nbr_read. Signed-off-by: Jason Lowe-Power <jason@lowepower.com> |
