2017-01-16net/mlx4_core: Fix when to save some qp context flags for dynamic VST to VGT ↵Jack Morgenstein
transitions Save the qp context flags byte containing the flag disabling vlan stripping in the RESET to INIT qp transition, rather than in the INIT to RTR transition. Per the firmware spec, the flags in this byte are active in the RESET to INIT transition. As a result of saving the flags in the incorrect qp transition, when switching dynamically from VGT to VST and back to VGT, the vlan remained stripped (as is required for VST) and did not return to not-stripped (as is required for VGT).

2017-01-16net/mlx4_core: Fix racy CQ (Completion Queue) freeJack Morgenstein
In function mlx4_cq_completion() and mlx4_cq_event(), the radix_tree_lookup requires a rcu_read_lock. This is mandatory: if another core frees the CQ, it could run the radix_tree_node_rcu_free() call_rcu() callback while its being used by the radix tree lookup function. Additionally, in function mlx4_cq_event(), since we are adding the rcu lock around the radix-tree lookup, we no longer need to take the spinlock. Also, the synchronize_irq() call for the async event eliminates the need for incrementing the cq reference count in mlx4_cq_event(). Other changes: 1. In function mlx4_cq_free(), replace spin_lock_irq with spin_lock: we no longer take this spinlock in the interrupt context. The spinlock here, therefore, simply protects against different threads simultaneously invoking mlx4_cq_free() for different cq's. 2. In function mlx4_cq_free(), we move the radix tree delete to before the synchronize_irq() calls. This guarantees that we will not access this cq during any subsequent interrupts, and therefore can safely free the CQ after the synchronize_irq calls. The rcu_read_lock in the interrupt handlers only needs to protect against corrupting the radix tree; the interrupt handlers may access the cq outside the rcu_read_lock due to the synchronize_irq calls which protect against premature freeing of the cq. 3. In function mlx4_cq_event(), we change the mlx_warn message to mlx4_dbg. 4. We leave the cq reference count mechanism in place, because it is still needed for the cq completion tasklet mechanism.

2017-01-16net/mlx5e: Fix a -Wmaybe-uninitialized warningArnd Bergmann
As found by Olof's build bot, we gain a harmless warning about a potential uninitialized variable reference in mlx5: drivers/net/ethernet/mellanox/mlx5/core/en_tc.c: In function 'parse_tc_fdb_actions': drivers/net/ethernet/mellanox/mlx5/core/en_tc.c:769:13: warning: 'out_dev' may be used uninitialized in this function [-Wmaybe-uninitialized] drivers/net/ethernet/mellanox/mlx5/core/en_tc.c:811:21: note: 'out_dev' was declared here This was introduced through the addition of an 'IS_ERR/PTR_ERR' pair that gcc is unfortunately unable to completely figure out. The problem being gcc cannot tell that if(IS_ERR()) in mlx5e_route_lookup_ipv4() is equivalent to checking if(err) later, so it assumes that 'out_dev' is used after the 'return PTR_ERR(rt)'. The PTR_ERR_OR_ZERO() case by comparison is fairly easy to detect by gcc, so it can't get that wrong, so it no longer warns. Hadar Hen Zion already attempted to fix the warning earlier by adding fake initializations, but that ended up not fully addressing all warnings, so I'm reverting it now that it is no longer needed.

2017-01-16ipvlan: fix dev_id creation corner case.Mahesh Bandewar
In the last patch da36e13cf65 ("ipvlan: improvise dev_id generation logic in IPvlan") I missed some part of Dave's suggestion and because of that the dev_id creation could fail in a corner case scenario. This would happen when more or less 64k devices have been already created and several have been deleted. If the devices that are still sticking around are the last n bits from the bitmap. So in this scenario even if lower bits are available, the dev_id search is so narrow that it always fails.

2017-01-16sfc: allow PIO more oftenEdward Cree
If an option descriptor has been sent on a queue but not followed by a packet, there will have been no completion event, so the read and write counts won't match and we'll think we can't do PIO. This combines with the fact that we have two TX queues (for en/disable checksum offload), and that both must be empty for PIO to happen. This patch adds a separate "packet_write_count" that tracks the most recent write_count we expect to see a completion event for; this excludes option descriptors but _includes_ PIO descriptors (even though they look like option descriptors). This is then used, rather than write_count, in efx_nic_tx_is_empty(). We only bother to maintain packet_write_count on EF10, since on Siena (a) there are no option descriptors and it always equals write_count, and (b) there's no PIO, so we don't need it anyway.

2017-01-16cxgb4: Shutdown adapter if firmware times out or errors outHariprasad Shenai
Perform an emergency shutdown of the adapter and stop it from continuing any further communication on the ports or DMA to the host. This is typically used when the adapter and/or firmware have crashed and we want to prevent any further accidental communication with the rest of the world. This will also force the port Link Status to go down -- if register writes work -- which should help our peers figure out that we're down.

2017-01-16be2net: fix MAC addr setting on privileged BE3 VFsIvan Vecera
During interface opening MAC address stored in netdev->dev_addr is programmed in the HW with exception of BE3 VFs where the initial MAC is programmed by parent PF. This is OK when MAC address is not changed when an interfaces is down. In this case the requested MAC is stored to netdev->dev_addr and later is stored into HW during opening. But this is not done for all BE3 VFs so the NIC HW does not know anything about this change and all traffic is filtered. This is the case of bonding if fail_over_mac == 0 where the MACs of the slaves are changed while they are down. The be2net behavior is too restrictive because if a BE3 VF has the FILTMGMT privilege then it is able to modify its MAC without any restriction. To solve the described problem the driver should take care about these privileged BE3 VFs so the MAC is programmed during opening. And by contrast unpriviled BE3 VFs should not be allowed to change its MAC in any case.

The #warning was present 10 years ago when the driver first got merged. As the platform is rather obsolete by now, it seems very unlikely that the warning will cause anyone to fix the code properly. kernelci.org reports the warning for every build in the meantime, so I think it's better to just turn it into a code comment to reduce noise.

2017-01-16ravb: do not use zero-length alignment DMA descriptorMasaru Nagai
Due to alignment requirements of the hardware transmissions are split into two DMA descriptors, a small padding descriptor of 0 - 3 bytes in length followed by a descriptor for rest of the packet. In the case of IP packets the first descriptor will never be zero due to the way that the stack aligns buffers for IP packets. However, for non-IP packets it may be zero. In that case it has been reported that timeouts occur, presumably because transmission stops at the first zero-length DMA descriptor and thus the packet is not transmitted. However, in my environment a BUG is triggered as follows: [ 20.381417] ------------[ cut here ]------------ [ 20.386054] kernel BUG at lib/swiotlb.c:495!

2017-01-13ath9k: move RELAY and DEBUG_FS to ATH9K[_HTC]_DEBUGFSChristian Lamparter
Currently, the common ath9k_common module needs to have a dependency on RELAY and DEBUG_FS in order to built. This is usually not a problem. But for RAM and FLASH starved AR71XX devices, every little bit counts. This patch adds a new symbol CONFIG_ATH9K_COMMON_DEBUG which makes it possible to drop the RELAY and DEBUG_FS dependency there and move it to ATH_(HTC)_DEBUGFS. Note: The shared FFT/spectral code (which is the only user of the relayfs in ath9k*) needs DEBUG_FS to export the relayfs interface to dump the data to userspace. So it makes no sense to have the functions compiled in, if DEBUG_FS is not there. Signed-off-by: Christian Lamparter <chunkeey@googlemail.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>

This is because the ath10k_wmi_10_4_op_pull_fw_stats() function tries to pull the same amount (num_peer_stats) for every statistic data unit.

Remove code that's no longer needed. It used to serve a purpose, which was to fix a link-related bug. For a while now, the NIC firmware has had a more elegant fix for that bug.

2017-01-12net: qcom/emac: grab a reference to the phydev on ACPI systemsTimur Tabi
Commit 6ffe1c4cd0a7 ("net: qcom/emac: fix of_node and phydev leaks") fixed the problem with reference leaks on phydev, but the fix is device-tree specific. When the driver unloads, the reference is dropped only on DT systems. Instead, it's cleaner if up grab an reference on ACPI systems. When the driver unloads, we can drop the reference without having to check whether we're on a DT system.

2017-01-12net: mdio-gpio: Use gpio subsystem to handle low-active pinsGuenter Roeck
gpiod functions support handling low-active pins, so we can move thos code out of this driver into the gpio subsystem and simplify the code a bit.

2017-01-12net: mdio-gpio: Convert to use gpiod functions where possibleGuenter Roeck
Using gpiod functions lets us use functionality which is not available with gpio functions. There is no gpiod function to match devm_gpio_request_one, so leave it in place and use gpio_to_desc() to convert absolute pin numbers to gpio descriptors.
