2017-06-29sfc: fix attempt to translate invalid filter IDEdward Cree1-3/+4
When filter insertion fails with no rollback, we were trying to convert EFX_EF10_FILTER_ID_INVALID to an id to store in 'ids' (which is either vlan->uc or vlan->mc). This would WARN_ON_ONCE and then record a bogus filter ID of 0x1fff, neither of which is a good thing.

2017-06-29mlxsw: spectrum_router: Fix NULL pointer dereferenceIdo Schimmel1-0/+3
In case a VLAN device is enslaved to a bridge we shouldn't create a router interface (RIF) for it when it's configured with an IP address. This is already handled by the driver for other types of netdevs, such as physical ports and LAG devices. If this IP address is then removed and the interface is subsequently unlinked from the bridge, a NULL pointer dereference can happen, as the original 802.1d FID was replaced with an rFID which was then deleted. To reproduce: $ ip link set dev enp3s0np9 up $ ip link add name enp3s0np9.111 link enp3s0np9 type vlan id 111 $ ip link set dev enp3s0np9.111 up $ ip link add name br0 type bridge $ ip link set dev br0 up $ ip link set enp3s0np9.111 master br0 $ ip address add dev enp3s0np9.111 192.168.0.1/24 $ ip address del dev enp3s0np9.111 192.168.0.1/24 $ ip link set dev enp3s0np9.111 nomaster Fixes: 99724c18fc66 ("mlxsw: spectrum: Introduce support for router interfaces") Signed-off-by: Ido Schimmel <idosch@mellanox.com> Reported-by: Petr Machata <petrm@mellanox.com> Tested-by: Petr Machata <petrm@mellanox.com> Reviewed-by: Petr Machata <petrm@mellanox.com> Signed-off-by: David S.

2017-06-23bnxt_en: Fix netpoll handling.Michael Chan1-6/+48
To handle netpoll properly, the driver must only handle TX packets during NAPI. Handling RX events cause warnings and errors in netpoll mode. The ndo_poll_controller() method should call napi_schedule() directly so that a NAPI weight of zero will be used during netpoll mode. The bnxt_en driver supports 2 ring modes: combined, and separate rx/tx. In separate rx/tx mode, the ndo_poll_controller() method will only process the tx rings. In combined mode, the rx and tx completion entries are mixed in the completion ring and we need to drop the rx entries and recycle the rx buffers. Add a function bnxt_force_rx_discard() to handle this in netpoll mode when we see rx entries in combined ring mode.

2017-06-19cxgb4: notify uP to route ctrlq compl to rdma rspqRaju Rangoju1-4/+6
During the module initialisation there is a possible race (basically race between uld and lld) where neither the uld nor lld notifies the uP about where to route the ctrl queue completions. LLD skips notifying uP as the rdma queues were not created by then (will leave it to ULD to notify the uP). As the ULD comes up, it also skips notifying the uP as the flag FULL_INIT_DONE is not set yet (ULD assumes that the interface is not up yet). Consequently, this race between uld and lld leaves uP unnotified about where to send the ctrl queue completions to, leading to iwarp RI_RES WR failure. Here is the race: CPU 0 CPU1 - allocates nic rx queus - t4_sge_alloc_ctrl_txq() (if rdma rsp queues exists, tell uP to route ctrl queue compl to rdma rspq) - acquires the mutex_lock - allocates rdma response queues - if FULL_INIT_DONE set, tell uP to route ctrl queue compl to rdma rspq - relinquishes mutex_lock - acquires the mutex_lock - enable_rx() - set FULL_INIT_DONE - relinquishes mutex_lock This patch fixes the above issue.

2017-06-12i40e: fix handling of HW ATR evictionJacob Keller4-7/+9
A recent commit to refactor the driver and remove the hw_disabled_flags field accidentally introduced two regressions. First, we overwrote pf->flags which removed various key flags including the MSI-X settings. Additionally, it was intended that we have now two flags, HW_ATR_EVICT_CAPABLE and HW_ATR_EVICT_ENABLED, but this was not done, and we accidentally were mis-using HW_ATR_EVICT_CAPABLE everywhere. This patch adds the missing piece, HW_ATR_EVICT_ENABLED, and safely updates pf->flags instead of overwriting it. Without this patch we will have many problems including disabling MSI-X support, and we'll attempt to use HW ATR eviction on devices which do not support it.

2017-06-11net: ena: fix race condition between submit and completion admin commandNetanel Belgazal1-4/+2
Bug: "Completion context is occupied" error printout will be noticed in dmesg. This error will cause the admin command to fail, which will lead to an ena_probe() failure or a watchdog reset (depends on which admin command failed). Root cause: __ena_com_submit_admin_cmd() is the function that submits new entries to the admin queue. The function have a check that makes sure the queue is not full and the function does not override any outstanding command. It uses head and tail indexes for this check. The head is increased by ena_com_handle_admin_completion() which runs from interrupt context, and the tail index is increased by the submit function (the function is running under ->q_lock, so there is no risk of multithread increment). Each command is associated with a completion context. This context allocated before call to __ena_com_submit_admin_cmd() and freed by ena_com_wait_and_process_admin_cq_interrupts(), right after the command was completed. This can lead to a state where the head was increased, the check passed, but the completion context is still in use. Solution: Use the atomic variable ->outstanding_cmds instead of using the head and the tail indexes. This variable is safe for use since it is bumped in get_comp_ctx() in __ena_com_submit_admin_cmd() and is freed by comp_ctxt_release() Fixes: 1738cd3ed342 ("Add a driver for Amazon Elastic Network Adapters (ENA)") Signed-off-by: Netanel Belgazal <netanel@amazon.com> Signed-off-by: David S.

2017-06-11net/mlx5e: Fix wrong indications in DIM due to counter wraparoundTal Gilboa2-7/+11
DIM (Dynamically-tuned Interrupt Moderation) is a mechanism designed for changing the channel interrupt moderation values in order to reduce CPU overhead for all traffic types. Each iteration of the algorithm, DIM calculates the difference in throughput, packet rate and interrupt rate from last iteration in order to make a decision. DIM relies on counters for each metric. When these counters get to their type's max value they wraparound. In this case the delta between 'end' and 'start' samples is negative and when translated to unsigned integers - very high. This results in a false indication to the algorithm and might result in a wrong decision. The fix calculates the 'distance' between 'end' and 'start' samples in a cyclic way around the relevant type's max value. It can also be viewed as an absolute value around the type's max value instead of around 0. Testing show higher stability in DIM profile selection and no wraparound issues.

Therefore, this commit replaces the smp_processor_id() in migration-enabled contexts by the appropriate get_cpu/put_cpu sections.

2017-06-10net: mvpp2: remove mvpp2_bm_cookie_{build,pool_get}Thomas Petazzoni1-33/+14
This commit removes the useless remove mvpp2_bm_cookie_{build,pool_get} functions. All what mvpp2_bm_cookie_build() was doing is compute a 32-bit value by concatenating the pool number and the CPU number... only to get the pool number re-extracted by mvpp2_bm_cookie_pool_get() later on. Instead, just get the pool number directly from RX descriptor status, and pass it to mvpp2_pool_refill() and mvpp2_rx_refill(). This has the added benefit of dropping a smp_processor_id() call in a migration-enabled context, which is wrong, and is the original motivation for making this change.

Commit 2b30842b23b9 ("net: fec: Clear and enable MIB counters on imx51") introduced fec_enet_clear_ethtool_stats(), but missed to add a stub for the CONFIG_M5272=y case, causing build failure for the m5272c3_defconfig. Add the missing empty stub to fix the build failure. Reported-by: Paul Gortmaker <paul.gortmaker@windriver.com> Signed-off-by: Fabio Estevam <fabio.estevam@nxp.com> Signed-off-by: David S.

2017-06-10bnx2x: Don't post statistics to malicious VFsMintz, Yuval2-1/+13
Once firmware indicates that a given VF is malicious and until that VF passes an FLR all bets are off - PF can't know anything is happening to the VF [since VF can't communicate anything to its PF]. But PF is currently still periodically asking device to collect statistics for the VF which might in turn fill logs by IOMMU blocking memory access done by the VF's PCI function [in the case VF has unmapped its buffers].

2017-06-10bnx2x: Allow vfs to disable txvlan offloadMintz, Yuval1-4/+15
VF clients are configured as enforced, meaning firmware is validating the correctness of their ethertype/vid during transmission. Once txvlan is disabled, VF would start getting SKBs for transmission here vlan is on the payload - but it'll pass the packet's ethertype instead of the vid, leading to firmware declaring it as malicious.

2017-06-08net: emac: fix and unify emac_mdio functionsChristian Lamparter1-23/+18
emac_mdio_read_link() was not copying the requested phy settings back into the emac driver's own phy api. This has caused a link speed mismatch issue for the AR8035 as the emac driver kept trying to connect with 10/100MBps on a 1GBit/s link. This patch also unifies shared code between emac_setup_aneg() and emac_mdio_setup_forced(). And furthermore it removes a chunk of emac_mdio_init_phy(), that was copying the same data into itself.
