2018-01-02macvlan: Fix one possible double freeGao Feng1-1/+6
Because the macvlan_uninit would free the macvlan port, so there is one double free case in macvlan_common_newlink. When the macvlan port is just created, then register_netdevice or netdev_upper_dev_link failed and they would invoke macvlan_uninit. Then it would reach the macvlan_port_destroy which triggers the double free. Signed-off-by: Gao Feng <gfree.wind@vip.163.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2018-01-02mlxsw: spectrum: Relax sanity checks during enslavementIdo Schimmel3-2/+17
Since commit 25cc72a33835 ("mlxsw: spectrum: Forbid linking to devices that have uppers") the driver forbids enslavement to netdevs that already have uppers of their own, as this can result in various ordering problems. This requirement proved to be too strict for some users who need to be able to enslave ports to a bridge that already has uppers. In this case, we can allow the enslavement if the bridge is already known to us, as any configuration performed on top of the bridge was already reflected to the device.

2018-01-02geneve: update skb dst pmtu on tx pathXin Long1-0/+14
Commit a93bf0ff4490 ("vxlan: update skb dst pmtu on tx path") has fixed a performance issue caused by the change of lower dev's mtu for vxlan. The same thing needs to be done for geneve as well. Note that geneve cannot adjust it's mtu according to lower dev's mtu when creating it. The performance is very low later when netperfing over it without fixing the mtu manually.

2017-12-31bpf: offload: allow netdev to disappear while verifier is runningJakub Kicinski3-3/+3
To allow verifier instruction callbacks without any extra locking NETDEV_UNREGISTER notification would wait on a waitqueue for verifier to finish. This design decision was made when rtnl lock was providing all the locking. Use the read/write lock instead and remove the workqueue. Verifier will now call into the offload code, so dev_ops are moved to offload structure. Since verifier calls are all under bpf_prog_is_dev_bound() we no longer need static inline implementations to please builds with CONFIG_NET=n.

Saeed Mahameed says: ==================== Mellanox, mlx5 E-Switch updates 2017-12-19 This series includes updates for mlx5 E-Switch infrastructures, to be merged into net-next and rdma-next trees. Mark's patches provide E-Switch refactoring that generalize the mlx5 E-Switch vf representors interfaces and data structures. The serious is mainly focused on moving ethernet (netdev) specific representors logic out of E-Switch (eswitch.c) into mlx5e representor module (en_rep.c), which provides better separation and allows future support for other types of vf representors (e.g. RDMA). Gal's patches at the end of this serious, provide a simple syntax fix and two other patches that handles vport ingress/egress ACL steering name spaces to be aligned with the Firmware/Hardware specs. V1->V2: - Addressed coding style comments in patches #1 and #7 - The series is still based on rc4, as now I see net-next is also @rc4. V2->V3: - Fixed compilation warning, reported by Dave.

2017-12-28net/mlx5e: Move ethernet representors data into separate structMark Bloch5-35/+60
Ethernet representors have a need to store data which is applicable only for them. Create a priv void pointer in struct mlx5_eswitch_rep and move mlx5e to store the relevant data there. As part of this change we also initialize rep_if in mlx5e_rep_register_vf_vports() as otherwise the E-Switch code will copy a priv value which is garbage. We also rename mlx5_eswitch_get_uplink_netdev() to mlx5_eswitch_get_uplink_priv() and make it return void *. This way E-Switch code doesn't need to deal with net devices and we leave the task of getting it to mlx5e.

2017-12-27bnx2x: Improve reliability in case of nested PCI errorsGuilherme G. Piccoli2-3/+15
While in recovery process of PCI error (called EEH on PowerPC arch), another PCI transaction could be corrupted causing a situation of nested PCI errors. Also, this scenario could be reproduced with error injection mechanisms (for debug purposes). We observe that in case of nested PCI errors, bnx2x might attempt to initialize its shmem and cause a kernel crash due to bad addresses read from MCP. Multiple different stack traces were observed depending on the point the second PCI error happens. This patch avoids the crashes by: * failing PCI recovery in case of nested errors (since multiple PCI errors in a row are not expected to lead to a functional adapter anyway), and by, * preventing access to adapter FW when MCP is failed (we mark it as failed when shmem cannot get initialized properly).

2017-12-27net: hns3: add support to update flow control settings after autonegPeng Li3-0/+41
When auto-negotiation is enabled, the MAC flow control settings is based on the flow control negotiation result. And it should be configured after a valid link has been established. This patch adds support to update flow control settings after auto-negotiation has completed.

2017-12-27net: hns3: fix for getting auto-negotiation state in hclge_get_autonegFuyun Liang1-0/+4
When phy exists, we use the value of phydev.autoneg to represent the auto-negotiation state of hardware. Otherwise, we use the value of mac.autoneg to represent it. This patch fixes for getting a error value of auto-negotiation state in hclge_get_autoneg().

2017-12-27net: hns3: cleanup mac auto-negotiation state queryFuyun Liang1-24/+0
When checking whether auto-negotiation is on, driver only needs to check the value of mac.autoneg(SW) directly, and does not need to query it from hardware. Because this value is always synchronized with the auto-negotiation state of hardware. This patch removes the mac auto-negotiation state query.
