2014-03-24vxlan: fix nonfunctional neigh_reduce()David Stevens
The VXLAN neigh_reduce() code is completely non-functional since check-in. Specific errors: 1) The original code drops all packets with a multicast destination address, even though neighbor solicitations are sent to the solicited-node address, a multicast address. The code after this check was never run. 2) The neighbor table lookup used the IPv6 header destination, which is the solicited node address, rather than the target address from the neighbor solicitation. So neighbor lookups would always fail if it got this far. Also for L3MISSes. 3) The code calls ndisc_send_na(), which does a send on the tunnel device. The context for neigh_reduce() is the transmit path, vxlan_xmit(), where the host or a bridge-attached neighbor is trying to transmit a neighbor solicitation. To respond to it, the tunnel endpoint needs to do a *receive* of the appropriate neighbor advertisement. Doing a send, would only try to send the advertisement, encapsulated, to the remote destinations in the fdb -- hosts that definitely did not do the corresponding solicitation. 4) The code uses the tunnel endpoint IPv6 forwarding flag to determine the isrouter flag in the advertisement. This has nothing to do with whether or not the target is a router, and generally won't be set since the tunnel endpoint is bridging, not routing, traffic. The patch below creates a proxy neighbor advertisement to respond to neighbor solicitions as intended, providing proper IPv6 support for neighbor reduction.

2014-03-24net: davinci_emac: Fix rollback of emac_dev_open()Christian Riesch
If an error occurs during the initialization in emac_dev_open() (the driver's ndo_open function), interrupts, DMA descriptors etc. must be freed. The current rollback code is buggy in several ways. 1) Freeing the interrupts. The current code will not free all interrupts that were requested by the driver. Furthermore, the code tries to do a platform_get_resource(priv->pdev, IORESOURCE_IRQ, -1) in its last iteration. This patch fixes these bugs. 2) Wrong order of err: and rollback: labels. If the setup of the PHY in the code fails, the interrupts that have been requested before are not freed: request irq if requesting irqs fails, goto rollback setup phy if phy setup fails, goto err return 0 rollback: free irqs err: This patch brings the code into the correct order. 3) The code calls napi_enable() and emac_int_enable(), but does not undo both in case of an error. This patch adds calls of emac_int_disable() and napi_disable() to the rollback code. 4) RX DMA descriptors are not freed in case of an error: Right before requesting the irqs, the function creates DMA descriptors for the RX channel. These RX descriptors are never freed when we jump to either rollback or err. This patch adds code for freeing the DMA descriptors in the case of an initialization error. This required a modification of cpdma_ctrl_stop() in davinci_cpdma.c: We must be able to call this function to free the DMA descriptors while the DMA channels are in IDLE state (before cpdma_ctlr_start() was called). Tested on a custom board with the Texas Instruments AM1808. Signed-off-by: Christian Riesch <christian.riesch@omicron.at> Signed-off-by: David S. Miller <davem@davemloft.net>
2014-03-24net: davinci_emac: Replace devm_request_irq with request_irqChristian Riesch
In commit 6892b41d9701283085b655c6086fb57a5d63fa47 Author: Lad, Prabhakar <prabhakar.csengg@gmail.com> Date: Tue Jun 25 21:24:51 2013 +0530 net: davinci: emac: Convert to devm_* api the call of request_irq is replaced by devm_request_irq and the call of free_irq is removed. But since interrupts are requested in emac_dev_open, doing ifconfig up/down on the board requests the interrupts again each time, causing devm_request_irq to fail. The interface is dead until the device is rebooted. This patch reverts said commit partially: It changes the driver back to use request_irq instead of devm_request_irq, puts free_irq back in place, but keeps the remaining changes of the original patch.

Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates This series contains updates to igb, ixgbe, ixgbevf, i40e and i40evf. Anjali provides a i40e/i40evf patch to add Energy Efficient Ethernet Low Power Idle stats and a fix for i40e to change the string "Side Band" to "Sideband" for consistency. Mitch provides 2 patches for i40evf to fix if the driver encounters an error while communicating with the PF driver, do not shut down the admin queue unconditionally. Add an error message when the admin queue message never completes and fix formatting on another message that was unnecessarily wrapped. Mark provides a ixgbe patch and five ixgbevf patches. Fix a possible infinite recursion when an adapter is removed and registers all read as all one's in ixgbe_clear_vmdq_generic() and ixgbe_clear_rar_generic(). Converts macros to static inline functions to align kernel coding standard and prepare for adding Live Error Recovery (LER) to ixgbevf. Change the ethtool register test to use the normal register accessor functions and eliminate macors used for calling register test functions to make error exits more clear. Checks all register reads for adapter removal by checking the status register after any register read that returns all F's since the status register will never return 0xFFFFFFFF unless the adapter is removed. Jacob implements SIOCGHWTSTAMP ioctl for igb which enables user processes to read the current hardware stamp config settings non-destructively. Todd adds the initial register read and write for surprise removal (LER) for igb. Christian Engelmayer fixes an igb memory leak in the igb_get_module_eeprom() error handling path. Ken Ichikawa provides a fix for igb, specifically for 82575 hardware to specify -1 to the phc_index for ethtool's get_ts_info, otherwise a wrong value will be set to the phc_index. Christopher Paasch fixes a null pointer dereference in igb and makes sure to unset the HAS_MSIX flag when the driver falls back to MSI only. ==================== Signed-off-by: David S.

2014-03-24gianfar: Fix P1010 config regression (SQ polling)Claudiu Manoil
The P1010 device tree restricts the number of supported interrupt groups to 1, although the eth controller can support 2 interrupt groups and the driver assumes the Multi-Group mode ("fsl,etsec2" model). So, in this case the assumption that the Multi-Group mode (MQ_MG_MODE) devices always support 2 interrupt groups is false. To fix this, a check for the actual number of interrupt groups enabled in the board's device tree has been added in gfar_probe for the "fsl,etsec2" devices. Without this fix, P1010 based boards claim support for 2 Tx queues to the net stack but only one is actually allocated, leading to NULL access in xmit. This issue was introduced by enabling Single-Queue polling for the P1010 devices. (71ff9e3 gianfar: Use Single-Queue polling for "fsl,etsec2") Fixes: 71ff9e3df7e1c5d3293af6b595309124e8c97412 Signed-off-by: Claudiu Manoil <claudiu.manoil@freescale.com> Signed-off-by: David S.
