When netdev is being allocated on initialization time, it allocates a private area, here struct ixgbe_adapter, that resides after the net_device structure. In ixgbe_probe(), the device init routine, we set up the adapter after alloc_etherdev_mq() on the private area and add a reference for the pci_dev as well via pci_set_drvdata(). Both in the error path of ixgbe_probe(), but also on module unload when ixgbe_remove() is being called, commit 41c62843 ("ixgbe: Fix rcu warnings induced by LER") accesses adapter after free_netdev(). The patch stores the result in a bool and thus fixes above oops on my side.

IXGBE adapter seems to require that VLAN filtering be enabled if VMDQ or SRIOV are enabled. When those functions are disabled, VLAN filtering may be disabled in promiscuous mode. Prior to commit a9b8943e ("ixgbe: remove vlan_filter_disable and enable functions") The logic was correct. However, after the commit the logic got reversed and VLAN filtered in now turned on when VMDQ/SRIOV is disabled. This patch changes the condition to enable hw vlan filtered when VMDQ or SRIOV is enabled.

This patch consolidates the logic behind dynamically setting TXDCTL.WTHRESH depending on interrupt throttle rate (ITR) setting regardless of BQL. Previously TXDCTL.WTHRESH was dynamically being set only with BQL being enabled, but we have to set it regardless of BQL when ITR is low to avoid Tx stalls/hangs.

This change removes the Rx buffer allocation at the end of ixgbe_clean_rx_irq. The reason for removing this is to avoid the extra latency introduced by the MMIO write.

Hardware has a limited number of pools available (64). Previously, no checks were in place to limit the number of accelerated macvlan devices based on the number of pools. Normally this would be ok, because there was already a limit for these well below the number of available pools. However, SR-IOV uses the very same pools. Therefor, we need to ensure that the total number of pools (number of VFs plus the number of non-VF pools in use for accelerated macvlans) does not exceed the number of pools available in hardware. This patch resolves a kernel NULL pointer dereference caused by the following commands: $modprobe ixgbe max_vfs=63 $ethtool -K eth2 l2-fwd-offload on $ip link add link eth2 macvlan0 type macvlan $ip link set dev macvlan0 up [ 992.950080] BUG: unable to handle kernel NULL pointer dereference at 0000000000000056 [ 992.951109] IP: [<ffffffffa003b71e>] ixgbe_disable_fwd_ring+0x1e/0xf0 [ixgbe] [ 992.951684] PGD 22a80e067 PUD 232e9b067 PMD 0 [ 992.952389] Oops: 0000 [#1] SMP [ 992.953014] Modules linked in: nfsd lockd nfs_acl exportfs auth_rpcgss oid_registry sunrpc bridge stp llc vhost_net macvtap macvlan vhost tun kvm_intel kvm ioatdma ixgbe mdio igb dca [ 992.956042] CPU: 2 PID: 11928 Comm: ifconfig Not tainted 3.16.0-rc6-net-next-07-29-2014-FCoE+ #1 [ 992.956915] Hardware name: Intel Corporation S2600CO/S2600CO, BIOS SE5C600.86B.02.03.0003.041920141333 04/19/2014 [ 992.957791] task: ffff8804341c0000 ti: ffff8801d7dc8000 task.ti: ffff8801d7dc8000 [ 992.958660] RIP: 0010:[<ffffffffa003b71e>] [<ffffffffa003b71e>] ixgbe_disable_fwd_ring+0x1e/0xf0 [ixgbe] [ 992.959613] RSP: 0018:ffff8801d7dcbbb8 EFLAGS: 00010286 [ 992.960093] RAX: 0000000000000001 RBX: 0000000000000000 RCX: 0000000000000001 [ 992.960575] RDX: ffff880232eb7000 RSI: 0000000000000000 RDI: ffff88022dc05800 [ 992.961059] RBP: ffff8801d7dcbbd8 R08: 0000000000000000 R09: 0000000000000000 [ 992.961541] R10: 0000000000000001 R11: 0000000000000000 R12: ffff88022ec20980 [ 992.962023] R13: ffff880232eb7000 R14: 0000000000000001 R15: 0000000000000001 [ 992.962508] FS: 00007fab264887a0(0000) GS:ffff880237640000(0000) knlGS:0000000000000000 [ 992.963378] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 [ 992.963858] CR2: 0000000000000056 CR3: 000000022a939000 CR4: 00000000001427e0 [ 992.964340] Stack: [ 992.964806] ffff88022ec28840 ffff88022ec20980 ffff88022dc05800 ffff880232eb7000 [ 992.965976] ffff8801d7dcbc28 ffffffffa003bae8 ffff8801d7dcbbe8 0000000000000400 [ 992.967147] 000000000000000d ffff88022ec20980 ffff88022ec20000 ffff88022dc05800 [ 992.968319] Call Trace: [ 992.968795] [<ffffffffa003bae8>] ixgbe_fwd_ring_up+0x88/0x280 [ixgbe] [ 992.969284] [<ffffffffa0041d83>] ixgbe_fwd_add+0x173/0x220 [ixgbe] [ 992.969767] [<ffffffffa015056c>] macvlan_open+0x1bc/0x230 [macvlan] [ 992.970256] [<ffffffff816b8de7>] __dev_open+0xd7/0x150 [ 992.970735] [<ffffffff816b8bd7>] __dev_change_flags+0xa7/0x170 [ 992.971220] [<ffffffff816b8ccb>] dev_change_flags+0x2b/0x70 [ 992.971703] [<ffffffff817471b2>] devinet_ioctl+0x602/0x6d0 [ 992.972184] [<ffffffff81748168>] inet_ioctl+0x78/0x90 [ 992.972666] [<ffffffff816a143b>] sock_do_ioctl+0x2b/0x70 [ 992.973146] [<ffffffff816a14ed>] sock_ioctl+0x6d/0x260 [ 992.973627] [<ffffffff811ad3b4>] do_vfs_ioctl+0x84/0x540 [ 992.974109] [<ffffffff811a4c81>] ? final_putname+0x21/0x50 [ 992.974593] [<ffffffff818725d5>] ? sysret_check+0x22/0x5d [ 992.975073] [<ffffffff811ad901>] SyS_ioctl+0x91/0xa0 [ 992.975550] [<ffffffff818725a9>] system_call_fastpath+0x16/0x1b [ 992.976026] Code: ff 66 66 66 2e 0f 1f 84 00 00 00 00 00 55 48 89 e5 48 83 ec 20 48 89 5d e8 4c 89 65 f0 48 89 f3 4c 89 6d f8 4c 8b a7 08 02 00 00 <44> 0f b6 6e 56 44 03 af 14 02 00 00 4c 89 e7 e8 5e f2 ff ff be [ 992.982261] RIP [<ffffffffa003b71e>] ixgbe_disable_fwd_ring+0x1e/0xf0 [ixgbe] [ 992.983212] RSP <ffff8801d7dcbbb8> [ 992.983681] CR2: 0000000000000056 [ 992.984248] ---[ end trace 9f54802b5cc3638b ]--- Cc: John Fastabend <john.r.fastabend@intel.com> Signed-off-by: NJacob Keller <jacob.e.keller@intel.com> Tested-by: NPhil Schmitt <phillip.j.schmitt@intel.com> Signed-off-by: NJeff Kirsher <jeffrey.t.kirsher@intel.com>

This patch prevents the display of the minimum link qualification check if we might be in a virtual machine. This check is incorrect and misleading in this case, since we actually don't really know what the available bandwidth is. To do so, we simply check whether each function on the bus matches our device id. If it doesn't the most likely scenario is that we're directly assigned to a virtual machine.

In cases where the driver is loaded while there are no SFP+ modules in the cage the interface was not being detected as SFP capable. To account for this the driver called identify_sfp in ixgbe_get_settings to make sure the data is correct. However when there is no SFP+ module in the cage the driver waits for the I2C reads to time out which can take more than a second and will cause issues with tools (like net-snmp) that may poll for that information. This patch resolves the issue by identifying interfaces with no PHY type set as SFP capable which allows the driver to detect the SFP module when the interface is brought up. As result of this we can also remove the identify_sfp call from ixgbe_get_settings. v2: remove the 82599 specific check since we have 82598 devices that are SFP capable.

Resume path calls .open but suspend path cannot call .stop because fdirs should not be freed and control over hardware should not be released until WoL is configured. To avoid having to duplicate all changes made in .stop on suspend path split out part of .stop that is relevant during suspend and call it from .stop and during suspend. This fix also ensures that ixgbe_ptp_suspend is called during the suspend path, and helps avoid similar errors. We can't call ixgbe_ptp_stop, since it will free the PTP clock device, which we shouldn't be doing during a suspend path.

VF can have a bandwidth of up to this value. o A new handler set_vf_rate for attr IFLA_VF_RATE has been introduced which takes 4 arguments: netdev, VF number, min_tx_rate, max_tx_rate o ndo_set_vf_rate replaces ndo_set_vf_tx_rate handler. o Drivers that currently implement ndo_set_vf_tx_rate should now call ndo_set_vf_rate instead and reject attempt to set a minimum bandwidth greater than 0 for IFLA_VF_TX_RATE when IFLA_VF_RATE is not yet implemented by driver. o If user enters only one of either min_tx_rate or max_tx_rate, then, userland should read back the other value from driver and set both for IFLA_VF_RATE. Drivers that have not yet implemented IFLA_VF_RATE should always return min_tx_rate as 0 when read from ip tool. o If both IFLA_VF_TX_RATE and IFLA_VF_RATE options are specified, then IFLA_VF_RATE should override. o Idea is to have consistent display of rate values to user. o Usage example: - ./ip link set p4p1 vf 0 rate 900 ./ip link show p4p1 32: p4p1: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN mode DEFAULT qlen 1000 link/ether 00:0e:1e:08:b0:f0 brd ff:ff:ff:ff:ff:ff vf 0 MAC 3e:a0:ca:bd:ae:5a, tx rate 900 (Mbps), max_tx_rate 900Mbps vf 1 MAC f6:c6:7c:3f:3d:6c vf 2 MAC 56:32:43:98:d7:71 vf 3 MAC d6:be:c3:b5:85:ff vf 4 MAC ee:a9:9a:1e:19:14 vf 5 MAC 4a:d0:4c:07:52:18 vf 6 MAC 3a:76:44:93:62:f9 vf 7 MAC 82:e9:e7:e3:15:1a ./ip link set p4p1 vf 0 max_tx_rate 300 min_tx_rate 200 ./ip link show p4p1 32: p4p1: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN mode DEFAULT qlen 1000 link/ether 00:0e:1e:08:b0:f0 brd ff:ff:ff:ff:ff:ff vf 0 MAC 3e:a0:ca:bd:ae:5a, tx rate 300 (Mbps), max_tx_rate 300Mbps, min_tx_rate 200Mbps vf 1 MAC f6:c6:7c:3f:3d:6c vf 2 MAC 56:32:43:98:d7:71 vf 3 MAC d6:be:c3:b5:85:ff vf 4 MAC ee:a9:9a:1e:19:14 vf 5 MAC 4a:d0:4c:07:52:18 vf 6 MAC 3a:76:44:93:62:f9 vf 7 MAC 82:e9:e7:e3:15:1a ./ip link set p4p1 vf 0 max_tx_rate 600 rate 300 ./ip link show p4p1 32: p4p1: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN mode DEFAULT qlen 1000 link/ether 00:0e:1e:08:b0:f brd ff:ff:ff:ff:ff:ff vf 0 MAC 3e:a0:ca:bd:ae:5, tx rate 600 (Mbps), max_tx_rate 600Mbps, min_tx_rate 200Mbps vf 1 MAC f6:c6:7c:3f:3d:6c vf 2 MAC 56:32:43:98:d7:71 vf 3 MAC d6:be:c3:b5:85:ff vf 4 MAC ee:a9:9a:1e:19:14 vf 5 MAC 4a:d0:4c:07:52:18 vf 6 MAC 3a:76:44:93:62:f9 vf 7 MAC 82:e9:e7:e3:15:1a Signed-off-by: NSucheta Chakraborty <sucheta.chakraborty@qlogic.com> Signed-off-by: NDavid S.

In line with changes done by Alex Duyck regarding unicast filters, we now only set multicast filters when the interface is not in promiscuous mode for multicast packets. This also has an impact on the RAR usage such that SR-IOV has some RARs reserved for its own usage.

Previously these functions handled stripping setup as well, but this has already been removed from these functions. Rather than encapsulating this into a function, we can just do the work directly in set_rx_mode.

Since fc.high_water is an array, we should treat low_water as an array also. This allows the algorithm to output different values for different TCs, and then we can distinguish between them. In addition, this patch changes one path that didn't honor the return value from ixgbe_setup_fc.

Time stamping resources are per-interface so there is no need to keep separate last_rx_timestamp for each Rx ring, move last_rx_timestamp to the adapter structure. With last_rx_timestamp inside adapter, ixgbe_ptp_rx_hwtstamp() inline function is reduced to a single if statement so it is no longer necessary. If statement is placed directly in ixgbe_process_skb_fields() fixing likely/unlikely marking. Checks for q_vector or adapter to be NULL are superfluous. Comment about taking I/O hit is a leftover from previous design.

There needs to be an indication when the service task has been initialized. This is because register access prior to that time can detect a removal and attempt to schedule the service task. Adding the __IXGBE_SERVICE_INITED bit allows this to be checked and if not set prevent the service task scheduling. By checking for a removal right after initialization, the probe can be failed at that point without getting the service task involved.

Resolve some rcu warnings produced when LER actions take place. This appears to be due to not holding the rtnl lock when calling ixgbe_down, so hold the lock. Also avoid disabling the device when it is already disabled. This check is necessary because the callback can be called more than once in some cases.

This patch moves the call to enable Tx queues after the link is established. Previously there was a chance for aggressive start_ndo_xmit() callers to sneak packets between enabling the Tx queues and the link coming up. In addition it replaces netif_tx_start_all_queues() with netif_tx_wake_all_queues() to allow for flushing of the qdisc.
