2017-04-05nfp: fix potential use after free on xdp progJakub Kicinski
We should unregister the net_device first, before we give back our reference on xdp_prog. Otherwise xdp_prog may be freed before .ndo_stop() disabled the datapath. Found by code inspection.

2017-04-04net: ethernet: ti: cpsw: fix race condition during open()Sekhar Nori
TI's cpsw driver handles both OF and non-OF case for phy connect. Unfortunately of_phy_connect() returns NULL on error while phy_connect() returns ERR_PTR(). To handle this, cpsw_slave_open() overrides the return value from phy_connect() to make it NULL or error. This leaves a small window, where cpsw_adjust_link() may be invoked for a slave while slave->phy pointer is temporarily set to -ENODEV (or some other error) before it is finally set to NULL. _cpsw_adjust_link() only handles the NULL case, and an oops results when ERR_PTR() is seen by it. Note that cpsw_adjust_link() checks PHY status for each slave whenever it is invoked. It can so happen that even though phy_connect() for a given slave returns error, _cpsw_adjust_link() is still called for that slave because the link status of another slave changed. Fix this by using a temporary pointer to store return value of {of_}phy_connect() and do a one-time write to slave->phy.

2017-03-29ezchip: nps_enet: check if napi has been completedZakharov Vlad
After a new NAPI_STATE_MISSED state was added to NAPI we can get into this state and in such case we have to reschedule NAPI as some work is still pending and we have to process it. napi_complete_done() function returns false if we have to reschedule something (e.g. in case we were in MISSED state) as current polling have not been completed yet. nps_enet driver hasn't been verifying the return value of napi_complete_done() and has been forcibly enabling interrupts. That is not correct as we should not enable interrupts before we have processed all scheduled work. As a result we were getting trapped in interrupt hanlder chain as we had never been able to disabale ethernet interrupts again. So this patch makes nps_enet_poll() func verify return value of napi_complete_done() and enable interrupts only in case all scheduled work has been completed.

Net device reset can fail when the h/w or f/w is in a bad state. Subsequent netdevice open fails in bnxt_hwrm_stat_ctx_alloc(). The cleanup invokes bnxt_hwrm_resource_free() which inturn calls bnxt_disable_int(). In this routine, the code segment if (ring->fw_ring_id != INVALID_HW_RING_ID) BNXT_CP_DB(cpr->cp_doorbell, cpr->cp_raw_cons); results in NULL pointer dereference as cpr->cp_doorbell is not yet initialized, and fw_ring_id is zero.

2017-03-22net: bcmgenet: remove bcmgenet_internal_phy_setup()Doug Berger
Commit 6ac3ce8295e6 ("net: bcmgenet: Remove excessive PHY reset") removed the bcmgenet_mii_reset() function from bcmgenet_power_up() and bcmgenet_internal_phy_setup() functions. In so doing it broke the reset of the internal PHY devices used by the GENETv1-GENETv3 which required this reset before the UniMAC was enabled. It also broke the internal GPHY devices used by the GENETv4 because the config_init that installed the AFE workaround was no longer occurring after the reset of the GPHY performed by bcmgenet_phy_power_set() in bcmgenet_internal_phy_setup(). In addition the code in bcmgenet_internal_phy_setup() related to the "enable APD" comment goes with the bcmgenet_mii_reset() so it should have also been removed. Commit bd4060a6108b ("net: bcmgenet: Power on integrated GPHY in bcmgenet_power_up()") moved the bcmgenet_phy_power_set() call to the bcmgenet_power_up() function, but failed to remove it from the bcmgenet_internal_phy_setup() function. Had it done so, the bcmgenet_internal_phy_setup() function would have been empty and could have been removed at that time. Commit 5dbebbb44a6a ("net: bcmgenet: Software reset EPHY after power on") was submitted to correct the functional problems introduced by commit 6ac3ce8295e6 ("net: bcmgenet: Remove excessive PHY reset"). It was included in v4.4 and made available on 4.3-stable. Unfortunately, it didn't fully revert the commit because this bcmgenet_mii_reset() doesn't apply the soft reset to the internal GPHY used by GENETv4 like the previous one did. This prevents the restoration of the AFE work- arounds for internal GPHY devices after the bcmgenet_phy_power_set() in bcmgenet_internal_phy_setup(). This commit takes the alternate approach of removing the unnecessary bcmgenet_internal_phy_setup() function which shouldn't have been in v4.3 so that when bcmgenet_mii_reset() was restored it should have only gone into bcmgenet_power_up(). This will avoid the problems while also removing the redundancy (and hopefully some of the confusion).

2017-03-22fjes: Do not load fjes driver if extended socket device is not power on.Yasuaki Ishimatsu
The extended device socket cannot turn on/off while system is running. So when system boots up and the device is not power on, the fjes driver does not need be loaded. To check the status of the device, the patch adds ACPI _STA method check.

2017-03-22fjes: Do not load fjes driver if system does not have extended socket device.Yasuaki Ishimatsu
The fjes driver is used only by FUJITSU servers and almost of all servers in the world never use it. But currently if ACPI PNP0C02 is defined in the ACPI table, the following message is always shown: "FUJITSU Extended Socket Network Device Driver - version 1.2 - Copyright (c) 2015 FUJITSU LIMITED" The message makes users confused because there is no reason that the message is shown in other vendor servers. To avoid the confusion, the patch adds a check that the server has a extended socket device or not.

2017-03-22net/mlx5e: Avoid supporting udp tunnel port ndo for VF repsPaul Blakey
This was added to allow the TC offloading code to identify offloading encap/decap vxlan rules. The VF reps are effectively related to the same mlx5 PCI device as the PF. Since the kernel invokes the (say) delete ndo for each netdev, the FW erred on multiple vxlan dst port deletes when the port was deleted from the system. We fix that by keeping the registration to be carried out only by the PF. Since the PF serves as the uplink device, the VF reps will look up a port there and realize if they are ok to offload that. Tested: <SETUP VFS> <SETUP switchdev mode to have representors> ip link add vxlan1 type vxlan id 44 dev ens5f0 dstport 9999 ip link set vxlan1 up ip link del dev vxlan1 Fixes: 4a25730eb202 ('net/mlx5e: Add ndo_udp_tunnel_add to VF representors') Signed-off-by: Paul Blakey <paulb@mellanox.com> Reviewed-by: Or Gerlitz <ogerlitz@mellanox.com> Signed-off-by: Saeed Mahameed <saeedm@mellanox.com> Signed-off-by: David S.

2017-03-22net/mlx5: E-Switch, Don't allow changing inline mode when flows are configuredRoi Dayan
Changing the eswitch inline mode can potentially cause already configured flows not to match the policy. E.g. set policy L4, add some L4 rules, set policy to L2 --> bad! Hence we disallow it. Keep track of how many offloaded rules are now set and refuse inline mode changes if this isn't zero.
