__napi_schedule_irqoff() is an optimized version of __napi_schedule() which can be used where it is known that interrupts are disabled, e.g. in interrupt-handlers, spin_lock_irq() sections or hrtimer callbacks. On PREEMPT_RT enabled kernels this assumptions is not true. Force- threaded interrupt handlers and spinlocks are not disabling interrupts and the NAPI hrtimer callback is forced into softirq context which runs with interrupts enabled as well. Chasing all usage sites of __napi_schedule_irqoff() is a whack-a-mole game so make __napi_schedule_irqoff() invoke __napi_schedule() for PREEMPT_RT kernels. The callers of ____napi_schedule() in the networking core have been audited and are correct on PREEMPT_RT kernels as well.

In the alx driver, all locking depended on the RTNL, but that causes issues with ipconfig ("ip=..." command line) because that waits for the netdev to have a carrier while holding the RTNL, but the alx workers etc. require RTNL, so the carrier won't be set until the RTNL is dropped and can be acquired by alx workers. This causes long delays at boot, as reported by Nikolai Zhubr. Really the only sensible thing to do here is to not use the RTNL for everything, but instead have fine-grained locking for just the driver. Do that, it's not that hard.

Even though the taprio qdisc is designed for multiqueue devices, all the queues still point to the same top-level taprio qdisc. This works and is probably required for software taprio, but at least with offload taprio, it has an undesirable side effect: because the whole qdisc is run when a packet has to be sent, it allows packets in a best-effort class to be processed in the context of a task sending higher priority traffic. If there are packets left in the qdisc after that first run, the NET_TX softirq is raised and gets executed immediately in the same process context. As with any other softirq, it runs up to 10 times and for up to 2ms, during which the calling process is waiting for the sendmsg call (or similar) to return. In my use case, that calling process is a real-time task scheduled to send a packet every 2ms, so the long sendmsg calls are leading to missed timeslots. By attaching each netdev queue to its own qdisc, as it is done with the "classic" mq qdisc, each traffic class can be processed independently without touching the other classes. A high-priority process can then send packets without getting stuck in the sendmsg call anymore. Signed-off-by: Yannick Vignon <yannick.vignon@nxp.com> Signed-off-by: David S.

This module's remove path calls del_timer(). However, that function does not wait until the timer handler finishes. This means that the timer handler may still be running after the driver's remove function has finished, which would result in a use-after-free. Fix by calling del_timer_sync(), which makes sure the timer handler has finished, and unable to re-schedule itself.

The rcu_head pointer passed to taprio_free_sched_cb is never NULL. That means that the result of container_of() operations on it is also never NULL, even though rcu_head is the first element of the structure embedding it. On top of that, it is misleading to perform a NULL check on the result of container_of() because the position of the contained element could change, which would make the check invalid. Remove the unnecessary NULL check. This change was made automatically with the following Coccinelle script. @@ type t; identifier v; statement s; @@ <+...

The WWAN framework provides a unified way to handle WWAN/modems and its control port(s). It has initially been introduced to support MHI/PCI modems, offering the same control protocols as the USB variants such as MBIM, QMI, AT... The WWAN framework exposes these control protocols as character devices, similarly to cdc-wdm, but in a bus agnostic fashion. This change adds registration of the USB modem cdc-wdm control endpoints to the WWAN framework as standard control ports (wwanXpY...). Exposing cdc-wdm through WWAN framework normally maintains backward compatibility, e.g: $ qmicli --device-open-qmi -d /dev/wwan0p1QMI --dms-get-ids instead of $ qmicli --device-open-qmi -d /dev/cdc-wdm0 --dms-get-ids However, some tools may rely on cdc-wdm driver/device name for device detection. It is then safer to keep the 'legacy' cdc-wdm character device to prevent any breakage. This is handled in this change by API mutual exclusion, only one access method can be used at a time, either cdc-wdm chardev or WWAN API. Note that unknown channel types (other than MBIM, AT or MBIM) are not registered to the WWAN framework. Signed-off-by: Loic Poulain <loic.poulain@linaro.org> Signed-off-by: David S.

Remove MODULE_VERSION(), as it doesn't seem to serve any practical purpose. For in-tree drivers, the kernel version matters. The code received lots of changes, but module version remained constant, since the driver landed in mainline. So, this version doesn't seem have any practical meaning anymore.

Radu Pirea says: ==================== Add PTP support for TJA1103 This is the PTP support for TJA1103. The RX timestamp is found in the reserved2 field of the PTP package. The TX timestamp has to be read from the phy registers. Reading of the timestamp works with interrupts or with polling(that starts when .nxp_c45_txtstamp is called). The implementation of .adjtime is done by read modify write because there is no way to atomically add/subtract a constant from the clock value.

When we call af_ops->set_link_af() we hold a RCU read lock as we retrieve af_ops from the RCU protected list, but this is unnecessary because we already hold RTNL lock, which is the writer lock for protecting rtnl_af_ops, so it is safer than RCU read lock. Similar for af_ops->validate_link_af(). This was not a problem until we begin to take mutex lock down the path of ->set_link_af() in __ipv6_dev_mc_dec() recently. We can just drop the RCU read lock there and assert RTNL lock.
