2018-12-21mlxsw: spectrum_switchdev: Fix VLAN device deletion via ioctlIdo Schimmel
[ Upstream commit 993107fea5eefdfdfde1ca38d3f01f0bebf76e77 ] When deleting a VLAN device using an ioctl the netdev is unregistered before the VLAN filter is updated via ndo_vlan_rx_kill_vid(). It can lead to a use-after-free in mlxsw in case the VLAN device is deleted while being enslaved to a bridge. The reason for the above is that when mlxsw receives the CHANGEUPPER event, it wrongly assumes that the VLAN device is no longer its upper and thus destroys the internal representation of the bridge port despite the reference count being non-zero. Fix this by checking if the VLAN device is our upper using its real device. In net-next I'm going to remove this trick and instead make mlxsw completely agnostic to the order of the events.

2018-12-21net: mvpp2: fix detection of 10G SFP modulesBaruch Siach
[ Upstream commit 01b3fd5ac97caffb8e5d5bd85086da33db3b361f ] The mvpp2_phylink_validate() relies on the interface field of phylink_link_state to determine valid link modes. However, when called from phylink_sfp_module_insert() this field in not initialized. The default switch case then excludes 10G link modes. This allows 10G SFP modules that are detected correctly to be configured at max rate of 2.5G. Catch the uninitialized PHY mode case, and allow 10G rates.

2018-12-21ethernet: fman: fix wrong of_node_put() in probe functionNicolas Saenz Julienne
[ Upstream commit ecb239d96d369c23c33d41708646df646de669f4 ] After getting a reference to the platform device's of_node the probe function ends up calling of_find_matching_node() using the node as an argument. The function takes care of decreasing the refcount on it. We are then incorrectly decreasing the refcount on that node again. This patch removes the unwarranted call to of_node_put().

[ Upstream commit c0f53771ba45745e5870daf880127925c93f232f ] The function lio_vf_rep_packet_sent_callback releases the occupation of sc via octeon_free_soft_command. sc should not be used after that.

[ Upstream commit 37c4b91f955fdd5f4ad771956b97d35f1321098e ] The last set of csum offload fixes had a leak: Checksum enabled status bits from rx descriptor were incorrectly interpreted.

2018-12-21net: stmmac: Move debugfs init/exit to ->probe()/->remove()Thierry Reding
[ Upstream commit 5f2b8b62786853341a20d4cd4948f9cbca3db002 ] Setting up and tearing down debugfs is current unbalanced, as seen by this error during resume from suspend: [ 752.134067] dwc-eth-dwmac 2490000.ethernet eth0: ERROR failed to create debugfs directory [ 752.134347] dwc-eth-dwmac 2490000.ethernet eth0: stmmac_hw_setup: failed debugFS registration The imbalance happens because the driver creates the debugfs hierarchy when the device is opened and tears it down when the device is closed. There's little gain in that, and it could be argued that it is even surprising because it's not usually done for other devices. Fix the imbalance by moving the debugfs creation and teardown to the driver's ->probe() and ->remove() implementations instead. Note that the ring descriptors cannot be read while the interface is down, so make sure to return an empty file when the descriptors_status debugfs file is read.

2018-12-17Revert "net/ibm/emac: wrong bit is used for STA control"Benjamin Herrenschmidt
[ Upstream commit 5b3279e2cba2238b37f6c18adfdea8bddb32715a ] This reverts commit 624ca9c33c8a853a4a589836e310d776620f4ab9. This commit is completely bogus. The STACR register has two formats, old and new, depending on the version of the IP block used. There's a pair of device-tree properties that can be used to specify the format used: has-inverted-stacr-oc has-new-stacr-staopc What this commit did was to change the bit definition used with the old parts to match the new parts. This of course breaks the driver on all the old ones. Instead, the author should have set the appropriate properties in the device-tree for the variant used on his board.

As 8139cp uses shared irq mode, other device irq will trigger cp_interrupt to execute. cp_change_mtu -> cp_close -> cp_open In cp_close routine just before free_irq(), some interrupt may occur. In my environment, cp_interrupt exectutes and IntrStatus is 0x4, exactly TxOk. That will cause cp_tx to wake device queue. As device queue is started, cp_start_xmit and cp_open will run at same time which will cause kernel BUG. For example: [#] for tx descriptor At start: [#][#][#] num_queued=3 After cp_init_hw->cp_start_hw->netdev_reset_queue: [#][#][#] num_queued=0 When 8139cp starts to work then cp_tx will check num_queued mismatchs the complete_bytes. The patch will check IntrMask before check IntrStatus in cp_interrupt. When 8139cp interrupt is disabled, just return. Signed-off-by: Su Yanjun <suyj.fnst@cn.fujitsu.com> Signed-off-by: David S.

interrupts [ Upstream commit 426a593e641ebf0d9288f0a2fcab644a86820220 ] In the original ftmac100_interrupt(), the interrupts are only disabled when the condition "netif_running(netdev)" is true. However, this condition causes kerenl hang in the following case. When the user requests to disable the network device, kernel will clear the bit __LINK_STATE_START from the dev->state and then call the driver's ndo_stop function. Network device interrupts are not blocked during this process. If an interrupt occurs between clearing __LINK_STATE_START and stopping network device, kernel cannot disable the interrupts due to the condition "netif_running(netdev)" in the ISR. Hence, kernel will hang due to the continuous interruption of the network device. In order to solve the above problem, the interrupts of the network device should always be disabled in the ISR without being restricted by the condition "netif_running(netdev)".

2018-12-13qed: Fix QM getters to always return a valid pqDenis Bolotin
[ Upstream commit eb62cca9bee842e5b23bd0ddfb1f271ca95e8759 ] The getter callers doesn't know the valid Physical Queues (PQ) values. This patch makes sure that a valid PQ will always be returned. The patch consists of 3 fixes: - When qed_init_qm_get_idx_from_flags() receives a disabled flag, it returned PQ 0, which can potentially be another function's pq. Verify that flag is enabled, otherwise return default start_pq. - When qed_init_qm_get_idx_from_flags() receives an unknown flag, it returned NULL and could lead to a segmentation fault. Return default start_pq instead. - A modulo operation was added to MCOS/VFS PQ getters to make sure the PQ returned is in range of the required flag.

[ Upstream commit bd85fbc2038a1bbe84990b23ff69b6fc81a32b2c ] When re-registering a user mr, the mpt information for the existing mr when running SRIOV is obtained via the QUERY_MPT fw command. The returned information includes the mpt's lkey. This retrieved mpt information is used to move the mpt back to hardware ownership in the rereg flow (via the SW2HW_MPT fw command when running SRIOV). The fw API spec states that for SW2HW_MPT, the lkey field must be zero. Any ConnectX-3 PF driver which checks for strict spec adherence will return failure for SW2HW_MPT if the lkey field is not zero (although the fw in practice ignores this field for SW2HW_MPT). Thus, in order to conform to the fw API spec, set the lkey field to zero before invoking SW2HW_MPT when running SRIOV.

In some cases there can be a race between the allocation or deallocation of the structure which was done in roce start / roce stop and an asynchrounous dcbx event that tries to access the structure. For this reason, we move the allocation of the rdma_info structure to be similar to the iscsi/fcoe info structures which are allocated during device setup. We add a new field of "active" to the struct to define whether roce has already been started or not, and this is checked instead of whether the pointer to the info structure.

2018-12-13bnx2x: Assign unique DMAE channel number for FW DMAE transactions.Sudarsana Reddy Kalluru
[ Upstream commit 77e461d14ed141253573eeeb4d34eccc51e38328 ] Driver assigns DMAE channel 0 for FW as part of START_RAMROD command. FW uses this channel for DMAE operations (e.g., TIME_SYNC implementation). Driver also uses the same channel 0 for DMAE operations for some of the PFs (e.g., PF0 on Port0). This could lead to concurrent access to the DMAE channel by FW and driver which is not legal. Hence need to assign unique DMAE id for FW. Currently following DMAE channels are used by the clients, MFW - OCBB/OCSD functionality uses DMAE channel 14/15 Driver 0-3 and 8-11 (for PF dmae operations) 4 and 12 (for stats requests) Assigning unique dmae_id '13' to the FW.

[ Upstream commit cc5922054131f9abefdc0622ae64fc55e6b2671d ] The lan743x driver, when under heavy traffic load, has been noticed to sometimes hang, or cause a kernel panic. Debugging reveals that the TX napi poll routine was returning the wrong value, 'weight'. Most other drivers return 0. And call napi_complete, instead of napi_complete_done. Additionally when creating the tx napi poll routine. Changed netif_napi_add, to netif_tx_napi_add. Updates for v3: changed 'fixes' tag to match defined format Updates for v2: use napi_complete, instead of napi_complete_done in lan743x_tx_napi_poll use netif_tx_napi_add, instead of netif_napi_add for registration of tx napi poll routine fixes: 23f0703c125b ("lan743x: Add main source files for new lan743x driver") Signed-off-by: Bryan Whitehead <Bryan.Whitehead@microchip.com> Signed-off-by: David S.

The consequence is that when exactly 32 macvlans are created on NIC, the last created macvlan receives no traffic because its MAC was not registered in HW.

2018-11-27net: aquantia: fix potential IOMMU fault after driver unbindDmitry Bogdanov
[ Upstream commit 7a1bb49461b12b2e6332a4d054256835f45203f3 ] IOMMU fault may occurr on unbind/bind or if_down/if_up sequence. Although driver disables the rings on down, this is not enough. Due to internal HW design, during subsequent initialization NIC sometimes may reuse RX descriptors cache and write to the host memory from the descriptor cache. That's get catched by IOMMU on host. This patch invalidates the descriptor cache in NIC on interface down to prevent writing to the cached descriptors and to the memory pointed in those descriptors.

2018-11-27i40e: restore NETIF_F_GSO_IPXIP[46] to netdev featuresJacob Keller
[ Upstream commit ba766b8b99c30ad3c55ed8cf224d1185ecff1476 ] Since commit bacd75cfac8a ("i40e/i40evf: Add capability exchange for outer checksum", 2017-04-06) the i40e driver has not reported support for IP-in-IP offloads. This likely occurred due to a bad rebase, as the commit extracts hw_enc_features into its own variable. As part of this change, it dropped the NETIF_F_FSO_IPXIP flags from the netdev->hw_enc_features. This was unfortunately not caught during code review. Fix this by adding back the missing feature flags. For reference, NETIF_F_GSO_IPXIP4 was added in commit 7e13318daa4a ("net: define gso types for IPx over IPv4 and IPv6", 2016-05-20), replacing NETIF_F_GSO_IPIP and NETIF_F_GSO_SIT. NETIF_F_GSO_IPXIP6 was added in commit bf2d1df39502 ("intel: Add support for IPv6 IP-in-IP offload", 2016-05-20).
