2016-10-17net: dsa: b53: Fix module autoloadJavier Martinez Canillas
If the driver is built as a module, autoload won't work because the module alias information is not filled. So user-space can't match the registered device with the corresponding module.

2016-10-17net: Require exact match for TCP socket lookups if dif is l3mdevDavid Ahern
Currently, socket lookups for l3mdev (vrf) use cases can match a socket that is bound to a port but not a device (ie., a global socket). If the sysctl tcp_l3mdev_accept is not set this leads to ack packets going out based on the main table even though the packet came in from an L3 domain. The end result is that the connection does not establish creating confusion for users since the service is running and a socket shows in ss output. Fix by requiring an exact dif to sk_bound_dev_if match if the skb came through an interface enslaved to an l3mdev device and the tcp_l3mdev_accept is not set. skb's through an l3mdev interface are marked by setting a flag in inet{6}_skb_parm. The IPv6 variant is already set; this patch adds the flag for IPv4. Using an skb flag avoids a device lookup on the dif. The flag is set in the VRF driver using the IP{6}CB macros. For IPv4, the inet_skb_parm struct is moved in the cb per commit 971f10eca186, so the match function in the TCP stack needs to use TCP_SKB_CB. For IPv6, the move is done after the socket lookup, so IP6CB is used. The flags field in inet_skb_parm struct needs to be increased to add another flag. There is currently a 1-byte hole following the flags, so it can be expanded to u16 without increasing the size of the struct.

2016-10-17memstick: rtsx_usb_ms: Manage runtime PM when accessing the deviceUlf Hansson
Accesses to the rtsx usb device, which is the parent of the rtsx memstick device, must not be done unless it's runtime resumed. This is currently not the case and it could trigger various errors. Fix this by properly deal with runtime PM in this regards. This means making sure the device is runtime resumed, when serving requests via the ->request() callback or changing settings via the ->set_param() callbacks.

2016-10-17irqchip/gic-v3-its: Fix 64bit GIC{R,ITS}_TYPER accessesMarc Zyngier
The GICv3 architecture specification mentions that a 64bit register can be accessed using two 32bit accesses. What it doesn't mention is that this is only guaranteed on a system that implements AArch32, and a pure AArch64 system is allowed not to support this. This causes issues with the GICR_TYPER and GITS_TYPER registers, which are both RO 64bit registers. In order to solve this, this patch switches the TYPER accesses to the gic_read_typer macro already used in other parts of the driver. This makes sure that we always use a 64bit access on 64bit systems, and two 32bit accesses on 32bit system. Signed-off-by: Marc Zyngier <marc.zyngier@arm.com>

2016-10-17Staging: wilc1000: Fix kernel Oops on opening the deviceAditya Shankar
Commit 2518ac59eb27 ("staging: wilc1000: Replace kthread with workqueue for host interface") adds an unconditional destroy_workqueue() on the wilc's "hif_workqueue" soon after its creation thereby rendering it unusable. It then further attempts to queue work onto this non-existing hif_worqueue and results in: Unable to handle kernel NULL pointer dereference at virtual address 00000010 pgd = de478000 [00000010] *pgd=3eec0831, *pte=00000000, *ppte=00000000 Internal error: Oops: 17 [#1] ARM Modules linked in: wilc1000_sdio(C) wilc1000(C) CPU: 0 PID: 825 Comm: ifconfig Tainted: G C 4.8.0-rc8+ #37 Hardware name: Atmel SAMA5 task: df56f800 task.stack: deeb0000 PC is at __queue_work+0x90/0x284 LR is at __queue_work+0x58/0x284 pc : [<c0126bb0>] lr : [<c0126b78>] psr: 600f0093 sp : deeb1aa0 ip : def22d78 fp : deea6000 r10: 00000000 r9 : c0a08150 r8 : c0a2f058 r7 : 00000001 r6 : dee9b600 r5 : def22d74 r4 : 00000000 r3 : 00000000 r2 : def22d74 r1 : 07ffffff r0 : 00000000 Flags: nZCv IRQs off FIQs on Mode SVC_32 ISA ARM Segment none ...

vmxnet3_set_mc() checks new_table_pa returned by dma_map_single() with dma_mapping_error(), but even there it assumes zero is invalid pa (it assumes dma_mapping_error(...,0) returns true if new_table is NULL). The patch adds an explicit variable to track status of new_table_pa. Found by Linux Driver Verification project (linuxtesting.org). v2: use "bool" and "true"/"false" for boolean variables.

2016-10-15net: qcom/emac: disable interrupts before calling phy_disconnectTimur Tabi
There is a race condition that can occur if EMAC interrupts are enabled when phy_disconnect() is called. phy_disconnect() sets adjust_link to NULL. When an interrupt occurs, the ISR might call phy_mac_interrupt(), which wakes up the workqueue function phy_state_machine(). This function might reference adjust_link, thereby causing a null pointer exception. Signed-off-by: Timur Tabi <timur@codeaurora.org> Signed-off-by: David S. Miller <davem@davemloft.net>

PCI devices that are 64-bit DMA capable should set the coherent DMA mask as well as the streaming DMA mask.

2016-10-14scsi: ipr: Fix async error WARN_ONBrian King
Commit afc3f83cb4a5 ("scsi: ipr: Add asynchronous error notification") introduced the warn on shown below. To fix this, rather than attempting to send the KOBJ_CHANGE uevent from interrupt context, which is what is causing the WARN_ON, just wake the ipr worker thread which will send a KOBJ_CHANGE uevent.
