2014-08-08net: axienet: delete unneeded test before of_node_putJulia Lawall1-2/+1
Of_node_put supports NULL as its argument, so the initial test is not necessary. Suggested by Uwe Kleine-König.

2014-08-07cxgb4: IEEE fixes for DCBx state machineAnish Bhatt5-71/+216
* Changes required due to 16eecd9be4b05 ("dcbnl : Fix misleading dcb_app->priority explanation") * Driver was previously not aware of what DCBx version was negotiated by firmware, this could lead to DCB app table in kernel or in firmware being populated wrong since IEEE/CEE used different formats made clear by above mentioned commit * Driver was missing a couple of state transitions that could be caused by other drivers that use chelsio hardware, resulting in incorrect behaviour (the change that addresses this also flips the state machine to switch on state instead of transition, hope this is okay in current window) * Prio queue info & tsa is no longer thrown away v2: Print DCBx state transition messages only when debug is enabled Signed-off-by: Anish Bhatt <anish@chelsio.com> Signed-off-by: David S.

This matches what the other drivers using fixed-link support do and restores the behaviour before commit 87009814cdbb ("ucc_geth: use the new fixed PHY helpers") for the affected device trees (i.e. no phy-handle and no fixed-link).

2014-08-07net: ucc_geth: make probe consistently acquire a reference to the phy nodeUwe Kleine-König1-1/+1
When the driver attaches to a device that has a phy handle the probe routine returns with a reference to that node. This reference is correctly dropped in the error path and the remove function. In the fixed phy case however no reference is acquired and so the error path might drop a reference the driver isn't holding. Fix that by getting a reference to the MAC.

2014-08-07net: ucc_geth: drop acquired references in probe error path and removeUwe Kleine-König1-1/+8

Make sure that fs_enet_probe is left with a reference to the phy node. In the presence of a phy handle this is already the case as of_parse_phandle returns a reference. In the fixed phy case a call to of_node_get is necessary. Otherwise the error path and remove function drop a reference the driver isn't holding.

2014-08-07net: gianfar: fix reference counting for phy_nodeUwe Kleine-König1-2/+2
The line before the changed if condition is: priv->phy_node = of_parse_phandle(np, "phy-handle", 0); . If this call succeeds priv->phy_node must not be overwritten in the if block; otherwise the reference to the node returned by of_parse_phandle is lost. So add a check that the if block isn't executed in this case. Furthermore in the fixed phy case no reference is aquired for phy_node resulting in an of_node_put without holding a reference. To fix that, get a reference on the MAC dt node.

A change added to the mdiobus/phy api added a module_get/module_put during phy connect/disconnect processing. Currently, the driver performs a phy connect during module probe and a phy disconnect during module remove. With the addition of the module_get during phy connect the amd-xgbe module use count is incremented and can no longer be unloaded. Move the phy connect/disconnect from the driver probe/remove functions to the net_device_ops ndo_open/ndo_stop functions. This allows the module use count to be decremented when the device(s) are brought down and allows the module to be unloaded.

2014-08-05net: sun4i-emac: fix memory leak on bad packetMarc Zyngier1-2/+4
Upon reception of a new frame, the emac driver checks for a number of error conditions, and flag the packet as "bad" if any of these are present. It then allocates a skb unconditionally, but only uses it if the packet is "good". On the error path, the skb is just forgotten, and the system leaks memory. The piece of junk I have on my desk seems to encounter such error frequently enough so that the box goes OOM after a couple of days, which makes me grumpy. Fix this by moving the allocation on the "good_packet" path (and convert it to netdev_alloc_skb while we're at it). Tested on a random Allwinner A20 board.

2014-08-05mlx4_core: Add support for secure-host and SMP firewallJack Morgenstein4-1/+105
Secure-host is the general term for the capability of a device to protect itself and the subnet from malicious host software. This is achieved by: 1. Not allowing un-trusted entities to access device configuration registers, directly (through pci_cr or pci_conf) and indirectly (through MADs). 2. Hiding M_Key from untrusted entities. 3. Preventing the modification of GUID0 by un-trusted entities 4. Not allowing drivers on untrusted hosts to receive nor to transmit packets over QP0 (SMP Firewall). The secure-host capability depends on firmware handling all QP0 packets, and not passing these packets up to the driver. Any information required by the driver for proper operation (e.g., SM lid) is passed via events generated by the firmware while processing QP0 MADs. Driver support mainly requires using the MAD_DEMUX FW command at startup, where the feature is enabled/disabled through a procedure described in the Mellanox HCA tools package.

2014-08-02i40evf: Fixed guest OS panic when removing vf driverSerey Kong1-2/+3
Removing VF driver during device still in reset caused guest OS panic. in the i40evf_remove(), we're trying to clean mac_filter_list which has not been initialized since the device is still stuck at the reset. The change is to initialize the filter_list before setting any task.

2014-08-02i40evf: fix memory leak on unused interfacesMitch Williams1-0/+24
If the driver is loaded and then unloaded before the interface is brought up, then it will allocate a MAC filter entry and never free it. To fix this, on unload, run through the mac filter list and free all the entries. We also do this during reset recovery when the driver cannot contact the PF and needs to shut down completely.

2014-08-02i40evf: don't leak queue vectorsMitch Williams1-0/+2
Fix a memory leak. Driver was allocating memory for queue vectors on init but not freeing them on shutdown. These need to be freed at two different times: during module unload, and during reset recovery when the driver cannot contact the PF driver and needs to give up.
