2024-09-10net: phy: dp83822: Fix NULL pointer dereference on DP83825 devicesTomas Paukrt
The probe() function is only used for DP83822 and DP83826 PHY, leaving the private data pointer uninitialized for the DP83825 models which causes a NULL pointer dereference in the recently introduced/changed functions dp8382x_config_init() and dp83822_set_wol(). Add the dp8382x_probe() function, so all PHY models will have a valid private data pointer to fix this issue and also prevent similar issues in the future.

2024-09-10Bluetooth: replace deprecated strncpy with strscpy_padJustin Stitt
strncpy() is deprecated for use on NUL-terminated destination strings [0] and as such we should prefer more robust and less ambiguous string interfaces. The CAPI (part II) [1] states that the manufacturer id should be a "zero-terminated ASCII string" and should "always [be] zero-terminated." Much the same for the serial number: "The serial number, a seven-digit number coded as a zero-terminated ASCII string". Along with this, its clear the original author intended for these buffers to be NUL-padded as well. To meet the specification as well as properly NUL-pad, use strscpy_pad(). In doing this, an opportunity to simplify this code is also present. Remove the min_t() and combine the length check into the main if.

For tracking multiple devices concurrently with a condition. The patch enables the HCI_QUIRK_USE_MSFT_EXT_ADDRESS_FILTER quirk on RTL8852B controller. The quirk setting is based on commit 9e14606d8f38 ("Bluetooth: msft: Extended monitor tracking by address filter") With this setting, when a pattern monitor detects a device, this feature issues an address monitor for tracking that device.

2024-09-10Bluetooth: Use led_set_brightness() in LED trigger activate() callbackHans de Goede
A LED trigger's activate() callback gets called when the LED trigger gets activated for a specific LED, so that the trigger code can ensure the LED state matches the current state of the trigger condition (LED_FULL when HCI_UP is set in this case). led_trigger_event() is intended for trigger condition state changes and iterates over _all_ LEDs which are controlled by this trigger changing the brightness of each of them. In the activate() case only the brightness of the LED which is being activated needs to change and that LED is passed as an argument to activate(), switch to led_set_brightness() to only change the brightness of the LED being activated.

Starting a BCM UART controller not defined as a platform device or a serdev with "btattach -B /dev/ttyS1 -P bcm -S 3000000" works fine but the serial port remains at the init_speed, i.e. 115200. The oper_speed is only set if a device is declared in ACPI, device tree or as a platform device.

2024-09-10net: ftgmac100: Enable TX interrupt to avoid TX timeoutJacky Chou
Currently, the driver only enables RX interrupt to handle RX packets and TX resources. Sometimes there is not RX traffic, so the TX resource needs to wait for RX interrupt to free. This situation will toggle the TX timeout watchdog when the MAC TX ring has no more resources to transmit packets. Therefore, enable TX interrupt to release TX resources at any time. When I am verifying iperf3 over UDP, the network hangs. Like the log below. root# iperf3 -c 192.168.100.100 -i1 -t10 -u -b0 Connecting to host 192.168.100.100, port 5201 [ 4] local 192.168.100.101 port 35773 connected to 192.168.100.100 port 5201 [ ID] Interval Transfer Bandwidth Total Datagrams [ 4] 0.00-20.42 sec 160 KBytes 64.2 Kbits/sec 20 [ 4] 20.42-20.42 sec 0.00 Bytes 0.00 bits/sec 0 [ 4] 20.42-20.42 sec 0.00 Bytes 0.00 bits/sec 0 [ 4] 20.42-20.42 sec 0.00 Bytes 0.00 bits/sec 0 [ 4] 20.42-20.42 sec 0.00 Bytes 0.00 bits/sec 0 [ 4] 20.42-20.42 sec 0.00 Bytes 0.00 bits/sec 0 [ 4] 20.42-20.42 sec 0.00 Bytes 0.00 bits/sec 0 [ 4] 20.42-20.42 sec 0.00 Bytes 0.00 bits/sec 0 [ 4] 20.42-20.42 sec 0.00 Bytes 0.00 bits/sec 0 [ 4] 20.42-20.42 sec 0.00 Bytes 0.00 bits/sec 0 - - - - - - - - - - - - - - - - - - - - - - - - - [ ID] Interval Transfer Bandwidth Jitter Lost/Total Datagrams [ 4] 0.00-20.42 sec 160 KBytes 64.2 Kbits/sec 0.000 ms 0/20 (0%) [ 4] Sent 20 datagrams iperf3: error - the server has terminated The network topology is FTGMAC connects directly to a PC.

2024-09-10net/smc: add sysctl for smc_limit_hsD. Wythe
In commit 48b6190a0042 ("net/smc: Limit SMC visits when handshake workqueue congested"), we introduce a mechanism to put constraint on SMC connections visit according to the pressure of SMC handshake process. At that time, we believed that controlling the feature through netlink was sufficient. However, most people have realized now that netlink is not convenient in container scenarios, and sysctl is a more suitable approach. In addition, since commit 462791bbfa35 ("net/smc: add sysctl interface for SMC") had introcuded smc_sysctl_net_init(), it is reasonable for us to initialize limit_smc_hs in it instead of initializing it in smc_pnet_net_int().

Daniel Machon says: ==================== net: lan966x: use the newly introduced FDMA library This patch series is the second of a 2-part series [1], that adds a new common FDMA library for Microchip switch chips Sparx5 and lan966x. These chips share the same FDMA engine, and as such will benefit from a common library with a common implementation. This also has the benefit of removing a lot of open-coded bookkeeping and duplicate code for the two drivers. In this second series, the FDMA library will be taken into use by the lan966x switch driver. ################### # Example of use: # ################### - Initialize the rx and tx fdma structs with values for: number of DCB's, number of DB's, channel ID, DB size (data buffer size), and total size of the requested memory. Also provide two callbacks: nextptr_cb() and dataptr_cb() for getting the nextptr and dataptr. - Allocate memory using fdma_alloc_phys() or fdma_alloc_coherent(). - Initialize the DCB's with fdma_dcb_init(). - Add new DCB's with fdma_dcb_add(). - Free memory with fdma_free_phys() or fdma_free_coherent(). ##################### # Patch breakdown: # ##################### Patch #1: select FDMA library for lan966x. Patch #2: includes the fdma_api.h header and removes old symbols. Patch #3: replaces old rx and tx variables with equivalent ones from the fdma struct. Only the variables that can be changed without breaking traffic is changed in this patch. Patch #4: uses the library for allocation of rx buffers. This requires quite a bit of refactoring in this single patch. Patch #5: uses the library for adding DCB's in the rx path. Patch #6: uses the library for freeing rx buffers. Patch #7: uses the library for allocation of tx buffers. This requires quite a bit of refactoring in this single patch. Patch #8: uses the library for adding DCB's in the tx path.

2024-09-09ionic: Allow XDP program to be hot swappedBrett Creeley
Using examples of other driver(s), add the ability to hot-swap an XDP program without having to reconfigure the queues. To prevent the q->xdp_prog to be read/written more than once use READ_ONCE() and WRITE_ONCE() on the q->xdp_prog. The q->xdp_prog was being checked in multiple different for loops in the hot path. The change to allow xdp_prog hot swapping created the possibility for many READ_ONCE(q->xdp_prog) calls during a single napi callback. Refactor the Rx napi handling to allow a previous READ_ONCE(q->xdp_prog) (or NULL for hwstamp_rxq) to be passed into the relevant functions. Also, move other Rx related hotpath handling into the newly created ionic_rx_cq_service() function to reduce the scope of the xdp_prog local variable and put all Rx handling in one function similar to Tx.
