A text cursor in the tty; LDLS sets net_device.priv_len ...
The virtual terminals never drew a cursor. Each now paints a steady
block (the cell with its colours swapped), erased before and redrawn
after every output byte, redrawn by a repaint, and hidden by
ESC [ ? 25 l as curses programs ask.
r8169 under LDLS on the TUF A15 got through probe and died in ndo_open
on __fortify_panic. netdev_priv() is `dev->priv` now, a flexible array
counted by net_device.priv_len, and rtl_open's memset of its ring
bookkeeping is bounds-checked against it. The allocator left priv_len
zero, so the driver saw an area of no bytes. It is set from BTF when the
kernel has the member. __fortify_panic also says which check, how many
bytes it had and wanted, and where from.
