net: txgbe: fix GPIO interrupt blocking

2024-05-30T07:49:52Z

[ Upstream commit b4a2496c17ed645f8d51061047c9c249b58c74ba ] The register of GPIO interrupt status is masked before MAC IRQ is enabled. This is because of hardware deficiency. So manually clear the interrupt status before using them. Otherwise, GPIO interrupts will never be reported again. There is a workaround for clearing interrupts to set GPIO EOI in txgbe_up_complete().

net: txgbe: fix to clear interrupt status after handling IRQ

2024-05-30T07:49:52Z

[ Upstream commit 0e71862a20d58b6e8d4c39de1d72c8919c4dccd1 ] GPIO EOI is not set to clear interrupt status after handling the interrupt. It should be done in irq_chip->irq_ack, but this function is not called in handle_nested_irq(). So executing function txgbe_gpio_irq_ack() manually in txgbe_gpio_irq_handler().

pwm: Fix setting period with #pwm-cells = <1> and of_pwm_single_xlate()

2024-05-30T07:49:52Z

[ Upstream commit 73dfe970c038d0548beccc5bfb2707e1d543b01f ] For drivers making use of of_pwm_single_xlate() (i.e. those that don't pass a hwpwm index) and also don't pass flags, setting period was wrongly skipped. This affects the pwm-pxa and ti-sn65dsi86 drivers.

io_uring/net: ensure async prep handlers always initialize ->done_io

2024-05-30T07:49:52Z

[ Upstream commit f3a640cca951ef9715597e68f5363afc0f452a88 ] If we get a request with IOSQE_ASYNC set, then we first run the prep async handlers. But if we then fail setting it up and want to post a CQE with -EINVAL, we use ->done_io. This was previously guarded with REQ_F_PARTIAL_IO, and the normal setup handlers do set it up before any potential errors, but we need to cover the async setup too.

l2tp: fix ICMP error handling for UDP-encap sockets

2024-05-30T07:49:52Z

[ Upstream commit 6e828dc60e509b79ef09882264952f341cb58425 ] Since commit a36e185e8c85 ("udp: Handle ICMP errors for tunnels with same destination port on both endpoints") UDP's handling of ICMP errors has allowed for UDP-encap tunnels to determine socket associations in scenarios where the UDP hash lookup could not. Subsequently, commit d26796ae58940 ("udp: check udp sock encap_type in __udp_lib_err") subtly tweaked the approach such that UDP ICMP error handling would be skipped for any UDP socket which has encapsulation enabled. In the case of L2TP tunnel sockets using UDP-encap, this latter modification effectively broke ICMP error reporting for the L2TP control plane. To a degree this isn't catastrophic inasmuch as the L2TP control protocol defines a reliable transport on top of the underlying packet switching network which will eventually detect errors and time out. However, paying attention to the ICMP error reporting allows for more timely detection of errors in L2TP userspace, and aids in debugging connectivity issues. Reinstate ICMP error handling for UDP encap L2TP tunnels: * implement struct udp_tunnel_sock_cfg .encap_err_rcv in order to allow the L2TP code to handle ICMP errors; * only implement error-handling for tunnels which have a managed socket: unmanaged tunnels using a kernel socket have no userspace to report errors back to; * flag the error on the socket, which allows for userspace to get an error such as -ECONNREFUSED back from sendmsg/recvmsg; * pass the error into ip[v6]_icmp_error() which allows for userspace to get extended error information via.

net: txgbe: use irq_domain for interrupt controller

2024-05-30T07:49:51Z

[ Upstream commit aefd013624a10f39b0bfaee8432a235128705380 ] In the current interrupt controller, the MAC interrupt acts as the parent interrupt in the GPIO IRQ chip. But when the number of Rx/Tx ring changes, the PCI IRQ vector needs to be reallocated. Then this interrupt controller would be corrupted. So use irq_domain structure to avoid the above problem.
