2020-01-21net: usb: lan78xx: Add .ndo_features_checkJames Hughes1-0/+15
As reported by Eric Dumazet, there are still some outstanding cases where the driver does not handle TSO correctly when skb's are over a certain size. Most cases have been fixed, this patch should ensure that forwarded SKB's that are greater than MAX_SINGLE_PACKET_SIZE - TX_OVERHEAD are software segmented and handled correctly.

2020-01-14r8152: add missing endpoint sanity checkJohan Hovold1-0/+3
Add missing endpoint sanity check to probe in order to prevent a NULL-pointer dereference (or slab out-of-bounds access) when retrieving the interrupt-endpoint bInterval on ndo_open() in case a device lacks the expected endpoints.

2020-01-14net: usb: lan78xx: limit size of local TSO packetsEric Dumazet1-0/+1
lan78xx_tx_bh() makes sure to not exceed MAX_SINGLE_PACKET_SIZE bytes in the aggregated packets it builds, but does nothing to prevent large GSO packets being submitted. Pierre-Francois reported various hangs when/if TSO is enabled. For localy generated packets, we can use netif_set_gso_max_size() to limit the size of TSO packets. Note that forwarded packets could still hit the issue, so a complete fix might require implementing .ndo_features_check for this driver, forcing a software segmentation if the size of the TSO packet exceeds MAX_SINGLE_PACKET_SIZE.

2019-12-12net: usb: lan78xx: Fix suspend/resume PHY register access errorCristian Birsan1-0/+1
Lan78xx driver accesses the PHY registers through MDIO bus over USB connection. When performing a suspend/resume, the PHY registers can be accessed before the USB connection is resumed. This will generate an error and will prevent the device to resume correctly. This patch adds the dependency between the MDIO bus and USB device to allow correct handling of suspend/resume.

2019-11-22r8152: avoid to call napi_disable twiceHayes Wang1-8/+20
Call napi_disable() twice would cause dead lock. There are three situations may result in the issue. 1. rtl8152_pre_reset() and set_carrier() are run at the same time. 2. Call rtl8152_set_tunable() after rtl8152_close(). 3. Call rtl8152_set_ringparam() after rtl8152_close(). For #1, use the same solution as commit 84811412464d ("r8152: Re-order napi_disable in rtl8152_close"). For #2 and #3, add checking the flag of IFF_UP and using napi_disable/napi_enable during mutex.

2019-11-20r8152: Re-order napi_disable in rtl8152_closePrashant Malani1-1/+1
Both rtl_work_func_t() and rtl8152_close() call napi_disable(). Since the two calls aren't protected by a lock, if the close function starts executing before the work function, we can get into a situation where the napi_disable() function is called twice in succession (first by rtl8152_close(), then by set_carrier()). In such a situation, the second call would loop indefinitely, since rtl8152_close() doesn't call napi_enable() to clear the NAPI_STATE_SCHED bit. The rtl8152_close() function in turn issues a cancel_delayed_work_sync(), and so it would wait indefinitely for the rtl_work_func_t() to complete. Since rtl8152_close() is called by a process holding rtnl_lock() which is requested by other processes, this eventually leads to a system deadlock and crash. Re-order the napi_disable() call to occur after the work function disabling and urb cancellation calls are issued.

Support the firmware of PHY NC which is used to fix the issue found for PHY. Currently, only RTL_VER_04, RTL_VER_05, and RTL_VER_06 need it. The order of loading PHY firmware would be RTL_FW_PHY_START RTL_FW_PHY_NC RTL_FW_PHY_STOP The RTL_FW_PHY_START/RTL_FW_PHY_STOP are used to lock/unlock the PHY, and set/clear the patch key from the firmware file.

2019-10-18net: usb: lan78xx: Connect PHY before registering MACAndrew Lunn1-6/+6
As soon as the netdev is registers, the kernel can start using the interface. If the driver connects the MAC to the PHY after the netdev is registered, there is a race condition where the interface can be opened without having the PHY connected. Change the order to close this race condition.

2019-10-16r8152: support request_firmware for RTL8153Hayes Wang1-12/+756
This patch supports loading additional firmware file through request_firmware(). A firmware file may include a header followed by several blocks which have different types of firmware. Currently, the supported types are RTL_FW_END, RTL_FW_PLA, and RTL_FW_USB. The firmware is used to fix some compatible or hardware issues. For example, the device couldn't be found after rebooting several times. The supported chips are RTL_VER_04 (rtl8153a-2.fw) RTL_VER_05 (rtl8153a-3.fw) RTL_VER_06 (rtl8153a-4.fw) RTL_VER_09 (rtl8153b-2.fw) Signed-off-by: Hayes Wang <[email protected]> Reviewed-by: Prashant Malani <[email protected]> Signed-off-by: David S.

2019-10-11net: usb: ax88179_178a: write mac to hardware in get_mac_addrPeter Fink1-0/+3
When the MAC address is supplied via device tree or a random MAC is generated it has to be written to the asix chip in order to receive any data. Previously in 9fb137aef34e ("net: usb: ax88179_178a: allow optionally getting mac address from device tree") this line was omitted because it seemed to work perfectly fine without it. But it was simply not detected because the chip keeps the mac stored even beyond a reset and it was tested on a hardware with an integrated UPS where the asix chip was permanently powered on even throughout power cycles.
