2016-05-16net: w5100: increase TX timeout periodAkinobu Mita1-1/+0
This increases TX timeout period from one second to 5 seconds which is the default value if the driver doesn't explicitly set net_device->watchdog_timeo. The one second timeout is too short for W5100 with SPI interface mode which doesn't support burst READ/WRITE processing in the SPI transfer. If the packet is transmitted while RX packets are being received at a very high rate, the TX transmittion work in the workqueue is delayed and the watchdog timer is expired.

2016-05-16net: dsa: mv88e6xxx: remove bridge workVivien Didelot2-34/+8
Now that the bridge code defers the switchdev port state setting, there is no need to defer the port STP state change within the mv88e6xxx code. Thus get rid of the driver's bridge work code. This also fixes a race condition where the DSA layer assumes that the bridge code already set the unbridged port's STP state to Disabled before restoring the Forwarding state. As a consequence, this also fixes the FDB flush for the unbridged port which now correctly occurs during the Forwarding to Disabled transition.

One cpu can be processing packets which includes using the cached route entries in the vrf device's private data and on another cpu the device gets deleted which releases the routes and sets the pointers in net_vrf to NULL.

2016-05-16net/mlx5_core: Flow counters infrastructureAmir Vadai4-2/+236
If a counter has the aging flag set when created, it is added to a list of counters that will be queried periodically from a workqueue. query result and last use timestamp are cached. add/del counter must be very efficient since thousands of such operations might be issued in a second. There is only a single reference to counters without aging, therefore no need for locks. But, counters with aging enabled are stored in a list. In order to make code as lockless as possible, all the list manipulation and access to hardware is done from a single context - the periodic counters query thread. The hardware supports multiple counters per FTE, however currently we are using one counter for each FTE. Signed-off-by: Amir Vadai <[email protected]> Signed-off-by: David S.

2016-05-16hv_netvsc: set nvdev link after populating chn_tableVitaly Kuznetsov1-11/+18
Crash in netvsc_send() is observed when netvsc device is re-created on mtu change/set channels. The crash is caused by dereferencing of NULL channel pointer which comes from chn_table. The root cause is a mixture of two facts: - we set nvdev pointer in net_device_context in alloc_net_device() before we populate chn_table. - we populate chn_table[0] only. The issue could be papered over by checking channel != NULL in netvsc_send() but populating the whole chn_table and writing the nvdev pointer afterwards seems more appropriate.

2016-05-16hv_netvsc: untangle the pointer messVitaly Kuznetsov4-122/+99
We have the following structures keeping netvsc adapter state: - struct net_device - struct net_device_context - struct netvsc_device - struct rndis_device - struct hv_device and there are pointers/dependencies between them: - struct net_device_context is contained in struct net_device - struct hv_device has driver_data pointer which points to 'struct net_device' OR 'struct netvsc_device' depending on driver's state (!). - struct net_device_context has a pointer to 'struct hv_device'. - struct netvsc_device has pointers to 'struct hv_device' and 'struct net_device_context'. - struct rndis_device has a pointer to 'struct netvsc_device'. Different functions get different structures as parameters and use these pointers for traveling. The problem is (in addition to keeping in mind this complex graph) that some of these structures (struct netvsc_device and struct rndis_device) are being removed and re-created on mtu change (as we implement it as re-creation of hyper-v device) so our travel using these pointers is dangerous. Simplify this to a the following: - add struct netvsc_device pointer to struct net_device_context (which is a part of struct net_device and thus never disappears) - remove struct hv_device and struct net_device_context pointers from struct netvsc_device - replace pointer to 'struct netvsc_device' with pointer to 'struct net_device'. - always keep 'struct net_device' in hv_device driver_data. We'll end up with the following 'circular' structure: net_device: [net_device_context] -> netvsc_device -> rndis_device -> net_device -> hv_device -> net_device On MTU change we'll be removing the 'netvsc_device -> rndis_device' branch and re-creating it making the synchronization easier. There is one additional redundant pointer left, it is struct net_device link in struct netvsc_device, it is going to be removed in a separate commit.

2016-05-16hv_netvsc: use start_remove flag to protect netvsc_link_change()Vitaly Kuznetsov1-4/+17
netvsc_link_change() can race with netvsc_change_mtu() or netvsc_set_channels() as these functions destroy struct netvsc_device and rndis filter. Use start_remove flag for syncronization. As netvsc_change_mtu()/netvsc_set_channels() are called with rtnl lock held we need to take it before checking start_remove value in netvsc_link_change().

2016-05-16ibft: Expose iBFT acpi header via sysfsDavid Bond2-1/+127
Some ethernet adapter vendors are supplying products which support optional (payed license) features. On some adapters this includes a hardware iscsi initiator. The same adapters in a normal (no extra licenses) mode of operation can be used as a software iscsi initiator. In addition, software iscsi boot initiators are becoming a standard part of many vendors uefi implementations. This is creating difficulties during early boot/install determining the proper configuration method for these adapters when they are used as a boot device. The attached patch creates sysfs entries to expose information from the acpi header of the ibft table. This information allows for a method to easily determining if an ibft table was created by a ethernet card's firmware or the system uefi/bios. In the case of a hardware initiator this information in combination with the pci vendor and device id can be used to ascertain any vendor specific behaviors that need to be accommodated.

The iBFT table only specifies a prefix length, not a netmask. And the netmask is pretty much pointless for IPv6. So introduce a new attribute 'prefix-len'. Some older user-space code might rely on the netmask attribute being present, so we should always display it.

2016-05-16drivers/of: Specify parent node in of_fdt_unflatten_tree()Gavin Shan3-6/+12
This adds one more argument to of_fdt_unflatten_tree() to specify the parent node of the FDT blob that is going to be unflattened. In the result, the function can be used to unflatten FDT blob that represents device sub-tree in PowerNV PCI hotplug driver.

2016-05-16drivers/of: Rename unflatten_dt_node()Gavin Shan1-7/+7
This renames unflatten_dt_node() to unflatten_dt_nodes() as it populates multiple device nodes from FDT blob. No logical changes introduced. Signed-off-by: Gavin Shan <[email protected]> Acked-by: Rob Herring <[email protected]> Signed-off-by: Rob Herring <[email protected]>
2016-05-16drivers/of: Avoid recursively calling unflatten_dt_node()Gavin Shan1-48/+74
In current implementation, unflatten_dt_node() is called recursively to unflatten device nodes in FDT blob. It's stress to limited stack capacity, especially to adopt the function to unflatten device sub-tree that possibly has multiple root nodes. In that case, we runs out of stack and the system can't boot up successfully. In order to reuse the function to unflatten device sub-tree, this avoids calling the function recursively, meaning the device nodes are unflattened in one call on unflatten_dt_node(): two arrays are introduced to track the parent path size and the device node of current level of depth, which will be used by the device node on next level of depth to be unflattened. All device nodes in more than 64 level of depth are dropped and hopefully, the system can boot up successfully with the partial device-tree. Also, the parameter "poffset" and "fpsize" are unused and dropped and the parameter "dryrun" is figured out from "mem == NULL". Besides, the return value of the function is changed to indicate the size of memory consumed by the unflatten device tree or error code.

2016-05-16drivers/of: Split unflatten_dt_node()Gavin Shan1-102/+147
The function unflatten_dt_node() is called recursively to unflatten device nodes and properties in the FDT blob. It looks complicated and hard to be understood. This splits the function into 3 functions: populate_properties(), populate_node() and unflatten_dt_node(). populate_properties(), which is called by populate_node(), creates properties for the indicated device node. The later one creates the device nodes from FDT blob. populate_node() gets the offset in FDT blob for next device nodes and then calls populate_node(). No logical changes introduced.
