r8152: simplify loops in generic_ocp_{read,write}()

2026-09-10T01:51:35+00:00

In generic_ocp_{read,write}(), the *while* loops look very strange: the last iteration is implemented differently to the previous ones (doing some useless assignments before *break*) for no good reason. Merge the different iterations into one, using the local variables in the loop bodies... Found by a static analysis tool.

net: usb: qmi_wwan: add Compal EXC-T1 support

2026-09-10T01:44:51+00:00

The Compal EXC-T1 is a Qualcomm MDM9207-based LTE modem which reports "EXC-x1" as its USB product string. It exposes its QMI function on interface 5. Add a fixed-interface match for the QMI function. Tested on a Compal EXC-T1 modem using an Ubuntu kernel build. Interface 5 bound to qmi_wwan and exposed cdc-wdm2 and wwan1.

net: usb: qmi_wwan: add Quectel RG660QB

2026-09-08T00:28:59+00:00

Add support for the Quectel RG660QB 5G module (USB ID 2c7c:013d). Its QMI interface (interface 4) uses class/subclass/protocol ff/ff/ff like the other recent Quectel modules, so match it the same way. The remaining interfaces are handled by the option driver. Tested with an early sample of the module on a Quectel 5G EVB connected over USB 3 to a Raspberry Pi 5: qmicli talks to the module via /dev/cdc-wdm0.

net: usb: cx82310_eth: drop URB after 0xffff reboot sentinel to prevent partial_data heap overflow

2026-09-04T23:05:48+00:00

The 0xffff length sentinel detects a router reboot and schedules re-enabling of ethernet mode, but then falls through to the rest of the loop body. The next check is } else if (len > CX82310_MTU) { which is the else of the just-matched if -- it never fires for len == 0xffff. The MTU bound that normally caps the incomplete-packet save path is silently bypassed. With 0xffff > skb->len always true (rx_urb_size is 4096), the incomplete-packet branch saves dev->partial_len = skb->len bytes into dev->partial_data. partial_data is kmalloc(hard_mtu) = kmalloc(CX82310_MTU + 2) = 1516 bytes, but skb->len after the 2-byte header pull can be up to 4094. A device that sends a 4096-byte URB starting with [0xff 0xff] therefore copies 4094 device-provided bytes into a buffer allocated for 1516 bytes, exceeding its requested size by 2578 bytes. The next URB then reads dev->partial_len (4094) back from the same 1516-byte buffer and dev->partial_rem (65535 - 4094 = 61441) from the new URB's ~4KB skb, both well past their allocations, and delivers the spliced result as a 64KB "frame" to the network stack. Bail out of rx_fixup after scheduling the re-enable work; the remainder of a reboot-marker URB is not meaningful packet data. This restores the invariant that partial_len < CX82310_MTU + 2 on the save path, since every other route there has already passed the MTU check.

net: usb: cdc_ncm: add Apple MacBook Pro USB product ID 0x1902

2026-08-20T21:47:29+00:00

The cdc_devs[] quirk table special-cases the Mac CDC-NCM private interface personality only for USB product ID 0x1905. Some MacBook Pro models (e.g. M1 Max) connected over a USB4/Thunderbolt 3/4 cable to a host whose Thunderbolt controller lacks PCIe tunneling support (no NHI function, USB4-only mode) present themselves with product ID 0x1902 instead, using the same descriptor layout as 0x1905: a Communications control interface with zero endpoints (no interrupt/status endpoint) paired with a CDC Data interface, at interface numbers 0 and 2. Because 0x1902 is unmatched, these devices fall through to the generic cdc_ncm_info driver_info, which sets FLAG_LINK_INTR and therefore requires an interrupt endpoint on the control interface. Apple's private NCM interface never provides one, so cdc_ncm_bind() fails outright: cdc_ncm 2-1:1.0: bind() failure cdc_ncm 2-1:1.2: bind() failure and no network device is created, breaking Ethernet-over-USB4 between the Mac and any USB4 host lacking Thunderbolt PCIe tunneling. Add matching entries for 0x1902 alongside the existing 0x1905 ones, reusing apple_private_interface_info as with the other Mac ID. Signed-off-by: Mehrdad Afshari Signed-off-by: Jakub Kicinski
