Likewise once a frame has been segmented, we should continue doing that and not try to convert it to a UFO frame.

| * geneve: maximum value of VNI cannot be usedGirish Moodalbail2017-08-091-1/+1
| | | | | | | | | | | | | | | | | | | | Geneve's Virtual Network Identifier (VNI) is 24 bit long, so the range of values for it would be from 0 to 16777215 (2^24 -1). However, one cannot create a geneve device with VNI set to 16777215. This patch fixes this issue. Signed-off-by: Girish Moodalbail <girish.moodalbail@oracle.com> Signed-off-by: David S.

| | | | | | | | | | | | | | | | | | | | | | With SYSTEMPORT Lite we have holes in our statistics layout that make us skip over the hardware MIB counters, bcm_sysport_get_stats() was not taking that into account resulting in reporting 0 for all SW-maintained statistics, fix this by skipping accordingly.

| * | sunvdc: prevent sunvdc panic when mpgroup disk added to guest domainJim Quigley2017-08-091-0/+61
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Using mpgroup to define multiple paths for a virtual disk causes multiple virtual-device-port ports to be created for that virtual device. Each virtual-device-port port then gets a vdisk created for it by the Linux sunvdc driver. As mpgroup is not supported by the Linux sunvdc driver it cannot handle multiple ports for a single vdisk, leading to a kernel panic at startup. This fix prevents more than one vdisk per virtual-device-port being created until full virtual disk multipathing (mpgroup) support is implemented.

It belongs to a separate group which can have 3 functions. Due to this the fix also have to update the way the functions are managed. Until now each groups used NB_FUNCS(which was 2) functions. For the mpp23, 3 functions are available but it is the only group which needs it, so on the loop involving NB_FUNCS an extra test was added to handle only the functions added. The bug was visible with the merge of the commit 07d065abf93d "arm64: dts: marvell: armada-3720-db: Add vqmmc regulator for SD slot", the gpio regulator used the gpio 23, due to this the whole rgmii group was setup to gpio which broke the Ethernet support on the Armada 3720 DB board. Thanks to this patch, the UHS SD cards (which need the vqmmc) _and_ the Ethernet work again.

This function is missing in old versions of A10/A20 SoCs' datasheets and user manuals, so it's also missing in the old drivers. The newest A10 Datasheet V1.70 and A20 Datasheet V1.41 contain this pin function, and it's discovered during implementing R40 pinctrl driver. Add it to the driver. As we now merged A20 pinctrl driver to the A10 one, we need to only fix the A10 driver now.

But __ppp_channel_push() can also send packets directly (using the .start_xmit() channel callback), in which case the xmit_recursion counter isn't incremented anymore. If such packets get routed back to the parent ppp unit, ppp_xmit_process() won't notice the recursion and will call ppp_channel_push() on the same channel, effectively creating the deadlock situation that the xmit_recursion mechanism was supposed to prevent. This patch re-introduces the xmit_recursion counter incrementation in ppp_channel_push(). Since the xmit_recursion variable is now part of the parent ppp unit, incrementation is skipped if the channel doesn't have any. This is fine because only packets routed through the parent unit may enter the channel recursively. Finally, we have to ensure that pch->ppp is not going to be modified while executing ppp_channel_push(). Instead of taking this lock only while calling ppp_xmit_process(), we now have to hold it for the full ppp_channel_push() execution. This respects the ppp locks ordering which requires locking ->upl before ->downl.

This means that if ax88772_unbind() is called within this time gap to free the memory of the parent private data structure then a memory leak of the part filled netdev buffer memory will occur. Therefore, create a new function asix_rx_fixup_common_free() to free the memory of the netdev buffer and add a call to asix_rx_fixup_common_free() from inside ax88772_unbind(). Consequently when an unbind occurs part way through receiving an Ethernet frame, the netdev buffer memory that is holding part of the received Ethernet frame will now be freed.

For example, rx->split_head was not being set to false after an error was detected so potentially could cause a malformed 32-bit Data header word to be formed. Therefore add function reset_asix_rx_fixup_info() to reset all the members of asix_rx_fixup_info so that future processing will start with known initial conditions. Also, if (skb->len != offset) becomes true then call reset_asix_rx_fixup_info() so that the processing of the next URB starts with known initial conditions. Without the call, the check does nothing which potentially could lead to a malfunction when the next URB is processed. In addition, for robustness, call reset_asix_rx_fixup_info() before every error path's "return 0". This ensures that the next URB is processed from known initial conditions.

The risks include: a) asynchronously freeing rx->ax_skb after passing the netdev buffer to the NAPI layer which might corrupt the backlog queue. b) erroneously reusing rx->ax_skb such as calling skb_put_data() multiple times which causes writing off the end of the netdev buffer. Therefore add a defensive rx->ax_skb = NULL after usbnet_skb_return() so that it is not possible to free rx->ax_skb or to apply skb_put_data() too many times.

Since the initial introduction of IGMP snooping in commit 3a49b4fde2a1 ("mlxsw: Adding layer 2 multicast support") the driver didn't correctly free these multicast groups upon ungraceful situations such as the removal of the upper bridge device or module removal. The correct way to fix this is to associate each MID with the bridge ports member in it and then drop the reference in case the bridge port is destroyed, but this will result in a lot more code and will be fixed in net-next. For now, upon module removal, traverse the MID list and release each one.

Fix that by re-allocating the memory after renegotation. SCRQ's can also be freed if a server capabilities request fails. If this were encountered during a device reset for example, SCRQ's may not be re-allocated. This operation is not necessary anymore so remove it.

Also when register_netdev() failed, netdev is freed without calling lan78xx_unbind(). Hence halting the failed cases right manner fixes the system crash/hung issue.
