2016-11-15mac80211_hwsim: fix beacon delta calculationBenjamin Beichler
Due to the cast from uint32_t to int64_t, a wrong next beacon timing is calculated and effectively the beacon timer stops working. This is especially bad for 802.11s mesh networks, because discovery breaks without beacons.

2016-11-15Fix USB CB/CBI storage devices with CONFIG_VMAP_STACK=yPetr Vandrovec
Some code (all error handling) submits CDBs that are allocated on the stack. This breaks with CB/CBI code that tries to create URB directly from SCSI command buffer - which happens to be in vmalloced memory with vmalloced kernel stacks. Let's make copy of the command in usb_stor_CB_transport.

2016-11-15gpio: do not double-check direction on sleeping chipsLinus Walleij
When locking a GPIO line as IRQ, we go to lengths to double-check that the line is really set as input before marking it as used for IRQ. This is not good on GPIO chips that can sleep, because this function is called in IRQ-safe context. Just skip this if it can't be checked quickly. Currently this happens on sleeping expanders such as STMPE or TC3589x: BUG: scheduling while atomic: swapper/1/0x00000002 Modules linked in: CPU: 0 PID: 1 Comm: swapper Not tainted 4.9.0-rc1+ #38 Hardware name: Nomadik STn8815 [<c000f2e0>] (unwind_backtrace) from [<c000d244>] (show_stack+0x10/0x14) [<c000d244>] (show_stack) from [<c0037b78>] (__schedule_bug+0x54/0x80) [<c0037b78>] (__schedule_bug) from [<c042df14>] (__schedule+0x3a0/0x460) [<c042df14>] (__schedule) from [<c042e028>] (schedule+0x54/0xb8) (...)

2016-11-14scsi: qla2xxx: do not abort all commands in the adapter during EEH recoveryMauricio Faria de Oliveira
The previous commit 1535aa75a3d8 ("qla2xxx: fix invalid DMA access after command aborts in PCI device remove") introduced a regression during an EEH recovery, since the change to the qla2x00_abort_all_cmds() function calls qla2xxx_eh_abort(), which verifies the EEH recovery condition but handles it heavy-handed. (commit a465537ad1a4 "qla2xxx: Disable the adapter and skip error recovery in case of register disconnect.") This problem warrants a more general/optimistic solution right into qla2xxx_eh_abort() (eg in case a real command abort arrives during EEH recovery, or if it takes long enough to trigger command aborts); but it's still worth to add a check to ensure the code added by the previous commit is correct and contained within its owner function. This commit just adds a 'if (!ha->flags.eeh_busy)' check around it. (ahem; a trivial fix for this -rc series; sorry for this oversight.) With it applied, both PCI device remove and EEH recovery works fine.

2016-11-14mlxsw: spectrum_router: Flush FIB tables during finiIdo Schimmel
Since commit b45f64d16d45 ("mlxsw: spectrum_router: Use FIB notifications instead of switchdev calls") we reflect to the device the entire FIB table and not only FIBs that point to netdevs created by the driver. During module removal, FIBs of the second type are removed following NETDEV_UNREGISTER events sent. The other FIBs are still present in both the driver's cache and the device's table. Fix this by iterating over all the FIB tables in the device and flush them. There's no need to take locks, as we're the only writer.

2016-11-14net: stmmac: Fix lack of link transition for fixed PHYsFlorian Fainelli
Commit 52f95bbfcf72 ("stmmac: fix adjust link call in case of a switch is attached") added some logic to avoid polling the fixed PHY and therefore invoking the adjust_link callback more than once, since this is a fixed PHY and link events won't be generated. This works fine the first time, because we start with phydev->irq = PHY_POLL, so we call adjust_link, then we set phydev->irq = PHY_IGNORE_INTERRUPT and we stop polling the PHY. Now, if we called ndo_close(), which calls both phy_stop() and does an explicit netif_carrier_off(), we end up with a link down. Upon calling ndo_open() again, despite starting the PHY state machine, we have PHY_IGNORE_INTERRUPT set, and we generate no link event at all, so the link is permanently down.

We get the following build error from UM Linux after adding an entry to drivers/iio/gyro/Kconfig that issues "select I2C_MUX": ERROR: "devm_ioremap_resource" [drivers/i2c/muxes/i2c-mux-reg.ko] undefined! ERROR: "of_address_to_resource" [drivers/i2c/muxes/i2c-mux-reg.ko] undefined! It appears that the I2C mux core code depends on HAS_IOMEM for historical reasons, while CONFIG_I2C_MUX_REG does *not* have a direct dependency on HAS_IOMEM. This creates a situation where a allyesconfig or allmodconfig for UM Linux will select I2C_MUX, and will implicitly enable I2C_MUX_REG as well, and the compilation will fail for the register driver. Fix this up by making I2C_MUX_REG depend on HAS_IOMEM and removing the dependency from I2C_MUX.

2016-11-14nvme-rdma: stop and free io queues on connect failureSteve Wise
While testing nvme-rdma with the spdk nvmf target over iw_cxgb4, I configured the target (mistakenly) to generate an error creating the NVMF IO queues. This resulted a "Invalid SQE Parameter" error sent back to the host on the first IO queue connect: [ 9610.928182] nvme nvme1: queue_size 128 > ctrl maxcmd 120, clamping down [ 9610.938745] nvme nvme1: creating 32 I/O queues. So nvmf_connect_io_queue() returns an error to nvmf_connect_io_queue() / nvmf_connect_io_queues(), and that is returned to nvme_rdma_create_io_queues(). In the error path, nvmf_rdma_create_io_queues() frees the queue tagset memory _before_ stopping and freeing the IB queues, which causes yet another touch-after-free crash due to SQ CQEs being flushed after the ib_cqe structs pointed-to by the flushed WRs have been freed (since they are part of the nvme_rdma_request struct). The fix is to stop and free the queues in nvmf_connect_io_queues() if there is an error connecting any of the queues.

2016-11-14nvmet-rdma: Fix possible NULL deref when handling rdma cm eventsBart Van Assche
When we initiate queue teardown sequence we call rdma_destroy_qp which clears cm_id->qp, afterwards we call rdma_destroy_id, but we might see a rdma_cm event in between with a cleared cm_id->qp so watch out for that and silently ignore the event because this means that the queue teardown sequence is in progress.

2016-11-13ntb_perf: potential info leak in debugfsDan Carpenter
This is a static checker warning, not something I'm desperately concerned about. But snprintf() returns the number of bytes that would have been copied if there were space. We really care about the number of bytes that actually were copied so we should use scnprintf() instead. It probably won't overrun, and in that case we may as well just use sprintf() but these sorts of things make static checkers and code reviewers happier.

2016-11-13sfc: clear napi_hash state when copying channelsBert Kenward
efx_copy_channel() doesn't correctly clear the napi_hash related state. This means that when napi_hash_add is called for that channel nothing is done, and we are left with a copy of the napi_hash_node from the old channel. When we later call napi_hash_del() on this channel we have a stale napi_hash_node. Corruption is only seen when there are multiple entries in one of the napi_hash lists. This is made more likely by having a very large number of channels. Testing was carried out with 512 channels - 32 channels on each of 16 ports. This failure typically appears as protection faults within napi_by_id() or napi_hash_add(). efx_copy_channel() is only used when tx or rx ring sizes are changed (ethtool -G).

Merge media fixes from Mauro Carvalho Chehab: "This contains two patches fixing problems with my patch series meant to make USB drivers to work again after the DMA on stack changes. The last patch on this series is actually not related to DMA on stack. It solves a longstanding bug affecting module unload, causing module_put() to be called twice. It was reported by the user who reported and tested the issues with the gp8psk driver with the DMA fixup patches. As we're late at -rc cycle, maybe you prefer to not apply it right now. If this is the case, I'll add to the pile of patches for 4.10. Exceptionally this time, I'm sending the patches via e-mail, because I'm on another trip, and won't be able to use the usual procedure until Monday.
