2014-09-05mlx4: only pull headers into skb headEric Dumazet
Use the new fancy eth_get_headlen() to pull exactly the headers into skb->head. This speeds up GRE traffic (or more generally tunneled traffuc), as GRO can aggregate up to 17 MSS per GRO packet instead of 8. (Pulling too much data was forcing GRO to keep 2 frags per MSS) Signed-off-by: Eric Dumazet <edumazet@google.com> Cc: Amir Vadai <amirv@mellanox.com> Signed-off-by: David S.

git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/net-next Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates 2014-09-04 This series contains updates to i40e, i40evf, ixgbe and ixgbevf. Catherine adds dual speed module support to i40e. Updates i40e to allow the user to change link settings when the link is down. Serey renames i40e_ndo_set_vf_spoofck() to i40e_ndo_set_vf_spookchk() to be more consistent with what is defined in netdev and removes a unnecessary variable assignment. Jesse makes a malicious driver detection warning only print if extended driver string is enabled for i40e. Fixes a panic under traffic load when resetting or if/whenever there was a Tx-timeout because we were enabling the Tx queue to early. Anjali fixes an issue when PF reset fails, where we were trying to restart the admin queue which has not been setup at that point. This resolves an occasional kernel panic when PF reset fails for some reason. Ethan Zhao replaces the use of a local i40e_vfs_are_assigned() with the global kernel pci_vfs_assigned() for i40e. Alex cleans up the FDB handling for ixgbe. This change makes it so that the behavior for FDB handling is consistent between both the SR-IOV and non-SR-IOV cases. The main change is that we perform bounds checking on the number of SR-IOV addresses regardless of if SR-IOV is enabled or not as we can only support a certain number of addresses in the hardware. Emil extends the pending Tx work check to the VF interfaces, where the driver initiates a reset of the interface on link loss with pending Tx work in order to clear the rings. Introduces a delay for 82599 VFs of at least 500 usecs to make sure the VFLINKS value is correct, since this bit tends to flap when a DA or SFP+ cable is disconnected. Jacob adds code comments in ixgbe to make it more obvious that we are resetting features based on the fact that we do not have MSI-X enabled, and cannot use the previous settings. Also resolves a kernel NULL pointer dereference by limiting the combined total of MACVLAN and SR-IOV VFs, since the 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, which would be ok since there was already a limit for these well below the number of available pools. However, SR-IOV uses the very same pools, therefore we need to ensure that the total number of pools does not exceed the number of pools available in the hardware. v2: - clean up code comment in patch 5 by replacing "an" with "auto negotiation" based on feedback from Sergei Shtylyov - removed un-necessary parenthesis around function call in patch 8 based on feedback from Sergei Shtylyov ====================
2014-09-05net: ethernet: cpsw: improve interrupt lookup logic in cpsw_probe()Daniel Mack
Simplify the interrupt resource lookup code in cpsw_probe() by the following: * Only look at the first member of the resource. As the driver only works for DT-enabled platforms anyway, a resource of type IORESOURCE_IRQ will only contain one single entry (res->start == res->end), so there is no need for the iteration. * Add a bounds check to avoid overflows if we are passed more than ARRAY_SIZE(priv->irqs_table) resources. * Assign 'ret' with the return value of devm_request_irq() so that cpsw_probe() returns the appropriate error code. * If devm_request_irq() fails, report the error code in the log message.

2014-09-04net: systemport: update UMAC_CMD only when link is detectedFlorian Fainelli
When we bring the interface down, phy_stop() will schedule the PHY state machine to call our link adjustment callback. By the time we do so, we may have clock gated off the SYSTEMPORT hardware block, and this will cause bus errors to happen in bcm_sysport_adj_link(): Make sure that we only touch the UMAC_CMD register when there is an actual link. This is safe to do for two reasons: - updating the Ethernet MAC registers only make sense when a physical link is present - the PHY library state machine first set phydev->link = 0 before invoking phydev->adjust_link in the PHY_HALTED case This is a similar fix to the GENET one: c677ba8b3c47650358572091ed8a6af50bfca877 ("net: bcmgenet: update UMAC_CMD only when link is detected").

2014-09-04ixgbe: limit combined total of macvlan and SR-IOV VFsJacob Keller
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: Jacob Keller <jacob.e.keller@intel.com> Tested-by: Phil Schmitt <phillip.j.schmitt@intel.com> Signed-off-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com>

2014-09-02be2net: fix log messages in lancer FW download pathKalesh AP
Log messages in the Lancer FW download path have issues such as: - a single message spanning multiple lines - the success message is logged even in failure cases - status codes are already logged in the FW cmd routines This patch fixes these issues.

2014-09-02be2net: shorten AMAP_GET/SET_BITS() macro callsSathya Perla
The AMAP_GET/SET_BITS() macro calls take structure name as a parameter and hence are long and span more than one line. Replace these calls with a wrapper macros for RX/Tx compls and TX wrb. This results in fewer lines and more readable code in be_main.c Signed-off-by: Sathya Perla <sathya.perla@emulex.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2014-09-02be2net: add a few log messagesSathya Perla
This patch adds the following log messages to help debugging failure cases: 1) log FW version number: this is useful when driver initialization fails and the FW version number cannot be queried via ethtool 2) per function resource limits for BEx chips: these values are currently being printed only for Skyhawk and Lancer 3) PCI BAR mapping failure 4) function_mode/caps queried from FW: this helps catch any FW bugs that could advertise wrong capabilities to the driver Signed-off-by: Sathya Perla <sathya.perla@emulex.com> Signed-off-by: David S.

2014-09-01net: systemport: tell RXCHK if we are using Broadcom tagsFlorian Fainelli
When Broadcom tags are enabled, e.g: when interfaced to an Ethernet switch, make sure that we tell the RXCHK engine that it should be expecting a 4-bytes Broadcom tag after the Ethernet MAC Source Address. Use netdev_uses_dsa() to check for that condition since that will tell us if a switch is attached to our network interface.
