2015-04-14bgmac: fix DMA rx corruptionFelix Fietkau1-9/+18
The driver needs to inform the hardware about the first invalid (not yet filled) rx slot, by writing its DMA descriptor pointer offset to the BGMAC_DMA_RX_INDEX register. This register was set to a value exceeding the rx ring size, effectively allowing the hardware constant access to the full ring, regardless of which slots are initialized. To fix this issue, always mark the last filled rx slot as invalid. Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: David S. Miller <davem@davemloft.net>

2015-04-14bgmac: increase rx ring size from 511 to 512Felix Fietkau1-1/+1
Limiting it to 511 looks like a failed attempt at leaving one descriptor empty to allow the hardware to stop processing a buffer that has not been prepared yet. However, this doesn't work because this affects the total ring size as well Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: David S. Miller <davem@davemloft.net>

2015-04-14bgmac: leave interrupts disabled as long as there is work to doFelix Fietkau2-22/+10
Always poll rx and tx during NAPI poll instead of relying on the status of the first interrupt. This prevents bgmac_poll from leaving unfinished work around until the next IRQ. In my tests this makes bridging/routing throughput under heavy load more stable and ensures that no new IRQs arrive as long as bgmac_poll uses up the entire budget.

git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/next-queue Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates 2015-04-11 This series contains updates to iflink, ixgbe and ixgbevf. The entire set of changes come from Vlad Zolotarov to ultimately add the ethtool ops to VF driver to allow querying the RSS indirection table and RSS random key. Currently we support only 82599 and x540 devices. On those devices, VFs share the RSS redirection table and hash key with a PF. Letting the VF query this information may introduce some security risks, therefore this feature will be disabled by default. The new netdev op allows a system administrator to change the default behaviour with "ip link set" command. The relevant iproute2 patch has already been sent and awaits for this series upstream. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

2015-04-10ixgbe: Add a RETA query command to VF-PF channel APIVlad Zolotarov2-0/+39
Add this new command for 82599 and x540 devices only. Support for other devices will be added later. 82599 and x540 VFs and PF share the same RSS redirection table (RETA). Therefore we just return it for all VFs. For 82599 and x540 RETA table is an array of 32 registers (128 bytes) and the maximum number of registers that may be delivered in a single VF-PF channel command is 15. On the other hand VFs of these devices can be configured to have up to 4 RSS queues. Therefore we will "compress" the RETA by transferring only 2 bits per entry and thereby it will take only 8 registers (DWORDS) to transfer the whole VF RETA. Thus this patch does the following: - Adds a new API version (to specify a new commands set). - Adds the IXGBE_VF_GET_RETA command to the VF-PF commands set.

2015-04-10ixgbe: Refactor the RSS configuration codeVlad Zolotarov2-44/+112
This patch is a preparation for enablement of ethtool RSS indirection table and hash key querying. We don't want to read registers every time the RSS info is queried. Therefore we will store its current content in the arrays in the adapter struct and will read it from there (instead of from registers) when requested. Will change the code that writes the indirection table and hash key into the HW registers to take its content from these arrays. This will also simplify the indirection table updating ethtool callback implementation in the future.

2015-04-10ixgbe: Remove NETIF_F_HW_VLAN_CTAG_FILTER from hw_featuresAlexander Duyck1-1/+1
This change makes it so that the HW_VLAN_CTAG_FILTER bit is not falsely advertised as being a feature that can be toggled on ixgbe parts. The driver was setting the bit in features and letting it be inherited by hw_features, however the driver was actually ignoring the value of the bit and just assuming it was always set. As a result VLAN filtering was always enabled which is a requirement for SR-IOV, VMDq, DCB, FCoE, and possibly other features within the adapters.

handle_offloads() calls skb_reset_inner_headers() to store the layer pointers to the encapsulated packet. However, we currently push the vlag tag (if there is one) onto the packet afterwards. This changes the MAC header for the encapsulated packet but it is not reflected in skb->inner_mac_header, which breaks GSO and drivers which attempt to use this for encapsulation offloads.

2015-04-09mlx4/mlx5: Use dma_wmb/rmb where appropriateAlexander Duyck4-10/+10
This patch should help to improve the performance of the mlx4 and mlx5 on a number of architectures. For example, on x86 the dma_wmb/rmb equates out to a barrer() call as the architecture is already strong ordered, and on PowerPC the call works out to a lwsync which is significantly less expensive than the sync call that was being used for wmb. I placed the new barriers between any spots that seemed to be trying to order memory/memory reads or writes, if there are any spots that involved MMIO I left the existing wmb in place as the new barriers cannot order transactions between coherent and non-coherent memories. v2: Reduced the replacments to just the spots where I could clearly identify the usage pattern.

2015-04-08vxlan: do not exit on error in vxlan_stop()WANG Cong1-4/+1
We need to clean up vxlan despite vxlan_igmp_leave() fails. This fixes the following kernel warning: WARNING: CPU: 0 PID: 6 at lib/debugobjects.c:263 debug_print_object+0x7c/0x8d() ODEBUG: free active (active state 0) object type: timer_list hint: vxlan_cleanup+0x0/0xd0 CPU: 0 PID: 6 Comm: kworker/u8:0 Not tainted 4.0.0-rc7+ #953 Hardware name: Bochs Bochs, BIOS Bochs 01/01/2011 Workqueue: netns cleanup_net 0000000000000009 ffff88011955f948 ffffffff81a25f5a 00000000253f253e ffff88011955f998 ffff88011955f988 ffffffff8107608e 0000000000000000 ffffffff814deba2 ffff8800d4e94000 ffffffff82254c30 ffffffff81fbe455 Call Trace: [<ffffffff81a25f5a>] dump_stack+0x4c/0x65 [<ffffffff8107608e>] warn_slowpath_common+0x9c/0xb6 [<ffffffff814deba2>] ? debug_print_object+0x7c/0x8d [<ffffffff81076116>] warn_slowpath_fmt+0x46/0x48 [<ffffffff814deba2>] debug_print_object+0x7c/0x8d [<ffffffff81666bf1>] ? vxlan_fdb_destroy+0x5b/0x5b [<ffffffff814dee02>] __debug_check_no_obj_freed+0xc3/0x15f [<ffffffff814df728>] debug_check_no_obj_freed+0x12/0x16 [<ffffffff8117ae4e>] slab_free_hook+0x64/0x6c [<ffffffff8114deaa>] ? kvfree+0x31/0x33 [<ffffffff8117dc66>] kfree+0x101/0x1ac [<ffffffff8114deaa>] kvfree+0x31/0x33 [<ffffffff817d4137>] netdev_freemem+0x18/0x1a [<ffffffff817e8b52>] netdev_release+0x2e/0x32 [<ffffffff815b4163>] device_release+0x5a/0x92 [<ffffffff814bd4dd>] kobject_cleanup+0x49/0x5e [<ffffffff814bd3ff>] kobject_put+0x45/0x49 [<ffffffff817d3fc1>] netdev_run_todo+0x26f/0x283 [<ffffffff817d4873>] ? rollback_registered_many+0x20f/0x23b [<ffffffff817e0c80>] rtnl_unlock+0xe/0x10 [<ffffffff817d4af0>] default_device_exit_batch+0x12a/0x139 [<ffffffff810aadfa>] ? wait_woken+0x8f/0x8f [<ffffffff817c8e14>] ops_exit_list+0x2b/0x57 [<ffffffff817c9b21>] cleanup_net+0x154/0x1e7 [<ffffffff8108b05d>] process_one_work+0x255/0x4ad [<ffffffff8108af69>] ? process_one_work+0x161/0x4ad [<ffffffff8108b4b1>] worker_thread+0x1cd/0x2ab [<ffffffff8108b2e4>] ? process_scheduled_works+0x2f/0x2f [<ffffffff81090686>] kthread+0xd4/0xdc [<ffffffff8109eca3>] ? local_clock+0x19/0x22 [<ffffffff810905b2>] ? __kthread_parkme+0x83/0x83 [<ffffffff81a31c48>] ret_from_fork+0x58/0x90 [<ffffffff810905b2>] ? __kthread_parkme+0x83/0x83 For the long-term, we should handle NETDEV_{UP,DOWN} event from the lower device of a tunnel device.

The numPosted field in the ERX Doorbell register is 8-bits wide. So the max buffers that we can post at a time is 255 and not 256 which we are doing currently. Signed-off-by: Ajit Khaparde <ajit.khaparde@emulex.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2015-04-08sfc: Revert SRIOV changes.David S. Miller16-454/+207
This reverts commits: d92916f71a57582ce7276547510cedb2c10b6bd6 ("sfc: Own header for nic-specific sriov functions,") 25672dba9535b804331145379c79f835ba2205c5 ("sfc: Enable VF's via a write to the sysfs file sriov_numvfs") As they break the build with SRIOV disabled and there is no easy way to fix it the way things are arranged.
