-Lennart reported the following race condition:
-
-\ e1000_watchdog_task
- \ e1000e_has_link
- \ hw->mac.ops.check_for_link() === e1000e_check_for_copper_link
- /* link is up */
- mac->get_link_status = false;
-
- /* interrupt */
- \ e1000_msix_other
- hw->mac.get_link_status = true;
-
- link_active = !hw->mac.get_link_status
- /* link_active is false, wrongly */
-
-This problem arises because the single flag get_link_status is used to
-signal two different states: link status needs checking and link status is
-down.
-
-Avoid the problem by using the return value of .check_for_link to signal
-the link status to e1000e_has_link().

-
-When e1000e_poll() is not fast enough to keep up with incoming traffic, the
-adapter (when operating in msix mode) raises the Other interrupt to signal
-Receiver Overrun.
-
-This is a double problem because 1) at the moment e1000_msix_other()
-assumes that it is only called in case of Link Status Change and 2) if the
-condition persists, the interrupt is repeatedly raised again in quick
-succession.
-
-Ideally we would configure the Other interrupt to not be raised in case of
-receiver overrun but this doesn't seem possible on this adapter. Instead,
-we handle the first part of the problem by reverting to the practice of
-reading ICR in the other interrupt handler, like before commit 16ecba59bc33
-("e1000e: Do not read ICR in Other interrupt"). Thanks to commit
-0a8047ac68e5 ("e1000e: Fix msi-x interrupt automask") which cleared IAME
-from CTRL_EXT, reading ICR doesn't interfere with RxQ0, TxQ0 interrupts
-anymore. We handle the second part of the problem by not re-enabling the
-Other interrupt right away when there is overrun. Instead, we wait until
-traffic subsides, napi polling mode is exited and interrupts are
-re-enabled.
-
