[PATCH v1] arm64: dts: imx8mm: fix missing pgc_vpu_* power domain parent

by Vitor Soares

From: Vitor Soares <vitor.soares(a)toradex.com> The pgc_vpu_* nodes miss the reference to the power domain parent, leading the system to hang during the resume.

[PATCH] random: handle creditable entropy from atomic process context

by Jason A. Donenfeld

The entropy accounting changes a static key when the RNG has initialized, since it only ever initializes once. Static key changes, however, cannot be made from atomic context, so depending on where the last creditable entropy comes from, the static key change might need to be deferred to a worker. Previously the code used the execute_in_process_context() helper function, which accounts for whether or not the caller is in_interrupt(). However, that doesn't account for the case where the caller is actually in process context but is holding a spinlock. This turned out to be the case with input_handle_event() in drivers/input/input.c contributing entropy: [<ffffffd613025ba0>] die+0xa8/0x2fc [<ffffffd613027428>] bug_handler+0x44/0xec [<ffffffd613016964>] brk_handler+0x90/0x144 [<ffffffd613041e58>] do_debug_exception+0xa0/0x148 [<ffffffd61400c208>] el1_dbg+0x60/0x7c [<ffffffd61400c000>] el1h_64_sync_handler+0x38/0x90 [<ffffffd613011294>] el1h_64_sync+0x64/0x6c [<ffffffd613102d88>] __might_resched+0x1fc/0x2e8 [<ffffffd613102b54>] __might_sleep+0x44/0x7c [<ffffffd6130b6eac>] cpus_read_lock+0x1c/0xec [<ffffffd6132c2820>] static_key_enable+0x14/0x38 [<ffffffd61400ac08>] crng_set_ready+0x14/0x28 [<ffffffd6130df4dc>] execute_in_process_context+0xb8/0xf8 [<ffffffd61400ab30>] _credit_init_bits+0x118/0x1dc [<ffffffd6138580c8>] add_timer_randomness+0x264/0x270 [<ffffffd613857e54>] add_input_randomness+0x38/0x48 [<ffffffd613a80f94>] input_handle_event+0x2b8/0x490 [<ffffffd613a81310>] input_event+0x6c/0x98 According to Guoyong, it's not really possible to refactor the various drivers to never hold a spinlock there. And in_atomic() isn't reliable. So, rather than trying to be too fancy, just punt the change in the static key to a workqueue always. There's basically no drawback of doing this, as the code already needed to account for the static key not changing immediately, and given that it's just an optimization, there's not exactly a hurry to change the static key right away, so deferal is fine.

[PATCH 2/2] serial: stm32: Reset .throttled state in .startup()

by Uwe Kleine-König

When an UART is opened that still has .throttled set from a previous open, the RX interrupt is enabled but the irq handler doesn't consider it. This easily results in a stuck irq with the effect to occupy the CPU in a tight loop. So reset the throttle state in .startup() to ensure that RX irqs are handled.

[PATCH 1/2] serial: stm32: Return IRQ_NONE in the ISR if no handling happend

by Uwe Kleine-König

If there is a stuck irq that the handler doesn't address, returning IRQ_HANDLED unconditionally makes it impossible for the irq core to detect the problem and disable the irq. So only return IRQ_HANDLED if an event was handled. A stuck irq is still problematic, but with this change at least it only makes the UART nonfunctional instead of occupying the (usually only) CPU by 100% and so stall the whole machine.

[PATCH] net: usb: ax88179_178a: avoid writing the mac address before first reading

by Jose Ignacio Tornos Martinez

After the commit d2689b6a86b9 ("net: usb: ax88179_178a: avoid two consecutive device resets"), reset operation, in which the default mac address from the device is read, is not executed from bind operation and the random address, that is pregenerated just in case, is direclty written the first time in the device, so the default one from the device is not even read. This writing is not dangerous because is volatile and the default mac address is not missed. In order to avoid this, do not allow writing a mac address directly into the device, if the default mac address from the device has not been read yet. cc: stable(a)vger.kernel.org # 6.6+ Fixes: d2689b6a86b9 ("net: usb: ax88179_178a: avoid two consecutive device resets") Reported-by: Jarkko Palviainen <jarkko.palviainen(a)gmail.com> Signed-off-by: Jose Ignacio Tornos Martinez <jtornosm(a)redhat.com> --- drivers/net/usb/ax88179_178a.c | 8 ++++++++ 1 file changed, 8 insertions(+) diff --git a/drivers/net/usb/ax88179_178a.c b/drivers/net/usb/ax88179_178a.c index 69169842fa2f..650bb7b6badf 100644 --- a/drivers/net/usb/ax88179_178a.c +++ b/drivers/net/usb/ax88179_178a.c @@ -174,6 +174,7 @@ struct ax88179_data { u32 wol_supported; u32 wolopts; u8 disconnecting; + u8 mac_address_read; }; struct ax88179_int_data { @@ -969,9 +970,12 @@ static int ax88179_change_mtu(struct net_device *net, int new_mtu) static int ax88179_set_mac_addr(struct net_device *net, void *p) { struct usbnet *dev = netdev_priv(net); + struct ax88179_data *ax179_data = dev->driver_priv; struct sockaddr *addr = p; int ret; + if (!ax179_data->mac_address_read) + return -EAGAIN; if (netif_running(net)) return -EBUSY; if (!is_valid_ether_addr(addr->sa_data)) @@ -1256,6 +1260,7 @@ static int ax88179_led_setting(struct usbnet *dev) static void ax88179_get_mac_addr(struct usbnet *dev) { + struct ax88179_data *ax179_data = dev->driver_priv; u8 mac[ETH_ALEN]; memset(mac, 0, sizeof(mac)); @@ -1281,6 +1286,9 @@ static void ax88179_get_mac_addr(struct usbnet *dev) ax88179_write_cmd(dev, AX_ACCESS_MAC, AX_NODE_ID, ETH_ALEN, ETH_ALEN, dev->net->dev_addr); + + ax179_data->mac_address_read = 1; + netdev_info(dev->net, "MAC address: %pM\n", dev->net->dev_addr); } static int ax88179_bind(struct usbnet *dev, struct usb_interface *intf) -- 2.44.0
