2016-05-16net: dsa: mv88e6xxx: remove bridge workVivien Didelot
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.

2016-05-16net: vrf: protect changes to private data with rcuDavid Ahern
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. This results in datapath dereferencing a NULL pointer. Fix by protecting access to dst's with rcu.

2016-05-16net/mlx5_core: Flow counters infrastructureAmir Vadai
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 <amirva@mellanox.com> Signed-off-by: David S.

2016-05-16hv_netvsc: set nvdev link after populating chn_tableVitaly Kuznetsov
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 Kuznetsov
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.

Kevin adds support to disable link on all ports and changes bits set for telling firmware the PHY needs to be modified by the driver. Anjali adds a feature to enable/disable all multicast for a trusted VF. Added priv-flag knob to configure global true promiscuous support. Shannon adds the support code for calling the admin queue API call aq_set_switch_config(). Mitch modifies the VF, to log a message if an untrusted VF attempts to configure promiscuous mode, but lies to it and returns everything is ok instead of returning an error. Corrects the logic for reporting the receive packet hash. Fixed the adding of a broadcast filter for VFs, since that all VSIs are configured to receive broadcasts as default, so do not need to add a filter. Catherine refactors the ethtool get_settings to report the possible supported link modes from what we know about the current PHY type and that with the firmware supported PHY types. Jacob changes the driver to use WARN_ONCE in order to highlight the issue, but do not display a warning every time when receive hang message is received. Akeem corrects receive ptype payload layer for non_tunneled IPv6, when it should be layer 4 for UDP, instead of layer 3.

2016-05-15bnxt_en: Improve the delay logic for firmware response.Michael Chan
The current code has 2 problems: 1. The maximum wait time is not long enough. It is about 60% of the duration specified by the firmware. It is calling usleep_range(600, 800) for every 1 msec we are supposed to wait. 2. The granularity of the delay is too coarse. Many simple firmware commands finish in 25 usec or less. We fix these 2 issues by multiplying the original 1 msec loop counter by 40 and calling usleep_range(25, 40) for each iteration. There is also a second delay loop to wait for the last DMA word to complete. This delay loop should be a very short 5 usec wait. This change results in much faster bring-up/down time: Before the patch: time ip link set p4p1 up real 0m0.120s user 0m0.001s sys 0m0.009s After the patch: time ip link set p4p1 up real 0m0.030s user 0m0.000s sys 0m0.010s Signed-off-by: Michael Chan <michael.chan@broadcom.com> Signed-off-by: David S.

This patch adds priv-flag knob to configure global true promisc support.

Since this a global setting for the whole device, the priv-flag is exposed only on the first PF of the device.

2016-05-13i40e: Add support for disabling all link and change bits needed for PHY ↵Kevin Scott
interactions Add flag to tell firmware to disable link on all ports. This patch changes the bits set for telling firmware the PHY needs to be modified by driver. Without this patch, the setting will only set that mode for the current port on the device. Because the MDIO interface is common for the copper device. The command needs to set the mode for all ports.
