2018-11-10r8152: Check for supported Wake-on-LAN ModesFlorian Fainelli
[ Upstream commit f2750df1548bd8a2b060eb609fc43ca82811af4c ] The driver does not check for Wake-on-LAN modes specified by an user, but will conditionally set the device as wake-up enabled or not based on that, which could be a very confusing user experience.

2018-07-22r8152: napi hangup fix after disconnectJiri Slaby
[ Upstream commit 0ee1f4734967af8321ecebaf9c74221ace34f2d5 ] When unplugging an r8152 adapter while the interface is UP, the NIC becomes unusable. usb->disconnect (aka rtl8152_disconnect) deletes napi. Then, rtl8152_disconnect calls unregister_netdev and that invokes netdev->ndo_stop (aka rtl8152_close). rtl8152_close tries to napi_disable, but the napi is already deleted by disconnect above. So the first while loop in napi_disable never finishes. This results in complete deadlock of the network layer as there is rtnl_mutex held by unregister_netdev. So avoid the call to napi_disable in rtl8152_close when the device is already gone. The other calls to usb_kill_urb, cancel_delayed_work_sync, netif_stop_queue etc. seem to be fine. The urb and netdev is not destroyed yet. Signed-off-by: Jiri Slaby <jslaby@suse.cz> Cc: linux-usb@vger.kernel.org Cc: netdev@vger.kernel.org Signed-off-by: David S.

2017-12-25r8152: prevent the driver from transmitting packets with carrier offhayeswang
[ Upstream commit 2f25abe6bac573928a990ccbdac75873add8127e ] The linking status may be changed when autosuspend. And, after autoresume, the driver may try to transmit packets when the device is carrier off, because the interrupt transfer doesn't update the linking status, yet. And, if the device is in ALDPS mode, the device would stop working. The another similar case is 1. unplug the cable. 2. interrupt transfer queue a work_queue for linking change. 3. device enters the ALDPS mode. 4. a tx occurs before the work_queue is called.

2016-10-30r8152: Fix broken RX checksums.Mark Lord
The r8152 driver has been broken since (approx) 3.16.xx when support was added for hardware RX checksums on newer chip versions. Symptoms include random segfaults and silent data corruption over NFS. The hardware checksum logig does not work on the VER_02 dongles I have here when used with a slow embedded system CPU. Google reveals others reporting similar issues on Raspberry Pi. So, disable hardware RX checksum support for VER_02, and fix an obvious coding error for IPV6 checksums in the same function. Because this bug results in silent data corruption, it is a good candidate for back-porting to -stable >= 3.16.xx. Signed-off-by: Mark Lord <mlord@pobox.com> Signed-off-by: David S.

2016-01-08r8152: fix the wake eventhayeswang
When the autosuspend is enabled and occurs before system suspend, we should wake the device before running system syspend. Then, we could change the wake event for system suspend. Otherwise, the device would resume the system when receiving any packet. Signed-off-by: Hayes Wang <hayeswang@realtek.com> Signed-off-by: David S. Miller <davem@davemloft.net>
