2017-01-31brcmfmac: allow wowlan support to be per deviceArend Van Spriel
The wowlan support is (partially) determined dynamic by checking the device/firmware capabilities. So they can differ per device. So it is not possible to use a static global. Instead use the global as a template and use kmemdup(). When kmemdup() fails the template is used unmodified.

Liam R. Howlett says: ==================== sparc64: Recover from userspace non-resumable PIO & MEM errors A non-resumable error from userspace is able to cause a kernel panic or trap loop due to the setup and handling of the queued traps once in the kernel. This patch series addresses both of these issues. The queues are fixed by simply zeroing the memory before use. PIO errors from userspace will result in a SIGBUS being sent to the user process. The MEM errors form userspace will result in a SIGKILL and also cause the offending pages to be claimed so they are no longer used in future tasks. SIGKILL is used to ensure that the process does not try to coredump and result in an attempt to read the memory again from within kernel space. Although there is a HV call to scrub the memory (mem_scrub), there is no easy way to guarantee that the real memory address(es) are not used by other tasks. Clearing the error with mem_scrub would zero the memory and cause the other processes to proceed with bad data. The handling of other non-resumable errors remain unchanged and will cause a panic. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

2017-01-30sparc64: Zero pages on allocation for mondo and error queues.Liam R. Howlett
Error queues use a non-zero first word to detect if the queues are full. Using pages that have not been zeroed may result in false positive overflow events. These queues are set up once during boot so zeroing all mondo and error queue pages is safe. Note that the false positive overflow does not always occur because the page allocation for these queues is so early in the boot cycle that higher number CPUs get fresh pages. It is only when traps are serviced with lower number CPUs who were given already used pages that this issue is exposed. Signed-off-by: Liam R.

2017-01-30net/mlx4_core: Avoid command timeouts during VF driver device shutdownJack Morgenstein
Some Hypervisors detach VFs from VMs by instantly causing an FLR event to be generated for a VF. In the mlx4 case, this will cause that VF's comm channel to be disabled before the VM has an opportunity to invoke the VF device's "shutdown" method. The result is that the VF driver on the VM will experience a command timeout during the shutdown process when the Hypervisor does not deliver a command-completion event to the VM. To avoid FW command timeouts on the VM when the driver's shutdown method is invoked, we detect the absence of the VF's comm channel at the very start of the shutdown process. If the comm-channel has already been disabled, we cause all FW commands during the device shutdown process to immediately return success (and thus avoid all command timeouts).

2017-01-30net: Avoid receiving packets with an l3mdev on unbound UDP socketsRobert Shearman
Packets arriving in a VRF currently are delivered to UDP sockets that aren't bound to any interface. TCP defaults to not delivering packets arriving in a VRF to unbound sockets. IP route lookup and socket transmit both assume that unbound means using the default table and UDP applications that haven't been changed to be aware of VRFs may not function correctly in this case since they may not be able to handle overlapping IP address ranges, or be able to send packets back to the original sender if required. So add a sysctl, udp_l3mdev_accept, to control this behaviour with it being analgous to the existing tcp_l3mdev_accept, namely to allow a process to have a VRF-global listen socket. Have this default to off as this is the behaviour that users will expect, given that there is no explicit mechanism to set unmodified VRF-unaware application into a default VRF.

2017-01-30gianfar: synchronize DMA API usage by free_skb_rx_queue w/ gfar_new_pageArseny Solokha
In spite of switching to paged allocation of Rx buffers, the driver still called dma_unmap_single() in the Rx queues tear-down path. The DMA region unmapping code in free_skb_rx_queue() basically predates the introduction of paged allocation to the driver. While being refactored, it apparently hasn't reflected the change in the DMA API usage by its counterpart gfar_new_page(). As a result, setting an interface to the DOWN state now yields the following: # ip link set eth2 down fsl-gianfar ffe24000.ethernet: DMA-API: device driver frees DMA memory with wrong function [device address=0x000000001ecd0000] [size=40] ------------[ cut here ]------------ WARNING: CPU: 1 PID: 189 at lib/dma-debug.c:1123 check_unmap+0x8e0/0xa28 CPU: 1 PID: 189 Comm: ip Tainted: G O 4.9.5 #1 task: dee73400 task.stack: dede2000 NIP: c02101e8 LR: c02101e8 CTR: c0260d74 REGS: dede3bb0 TRAP: 0700 Tainted: G O (4.9.5) MSR: 00021000 <CE,ME> CR: 28002222 XER: 00000000 GPR00: c02101e8 dede3c60 dee73400 000000b6 dfbd033c dfbd36c4 1f622000 dede2000 GPR08: 00000007 c05b1634 1f622000 00000000 22002484 100a9904 00000000 00000000 GPR16: 00000000 db4c849c 00000002 db4c8480 00000001 df142240 db4c84bc 00000000 GPR24: c0706148 c0700000 00029000 c07552e8 c07323b4 dede3cb8 c07605e0 db535540 NIP [c02101e8] check_unmap+0x8e0/0xa28 LR [c02101e8] check_unmap+0x8e0/0xa28 Call Trace: [dede3c60] [c02101e8] check_unmap+0x8e0/0xa28 (unreliable) [dede3cb0] [c02103b8] debug_dma_unmap_page+0x88/0x9c [dede3d30] [c02dffbc] free_skb_resources+0x2c4/0x404 [dede3d80] [c02e39b4] gfar_close+0x24/0xc8 [dede3da0] [c0361550] __dev_close_many+0xa0/0xf8 [dede3dd0] [c03616f0] __dev_close+0x2c/0x4c [dede3df0] [c036b1b8] __dev_change_flags+0xa0/0x174 [dede3e10] [c036b2ac] dev_change_flags+0x20/0x60 [dede3e30] [c03e130c] devinet_ioctl+0x540/0x824 [dede3e90] [c0347dcc] sock_ioctl+0x134/0x298 [dede3eb0] [c0111814] do_vfs_ioctl+0xac/0x854 [dede3f20] [c0111ffc] SyS_ioctl+0x40/0x74 [dede3f40] [c000f290] ret_from_syscall+0x0/0x3c --- interrupt: c01 at 0xff45da0 LR = 0xff45cd0 Instruction dump: 811d001c 7c66482e 813d0020 9061000c 807f000c 5463103a 7cc6182e 3c60c052 386309ac 90c10008 4cc63182 4826b845 <0fe00000> 4bfffa60 3c80c052 388402c4 ---[ end trace 695ae6d7ac1d0c47 ]--- Mapped at: [<c02e22a8>] gfar_alloc_rx_buffs+0x178/0x248 [<c02e3ef0>] startup_gfar+0x368/0x570 [<c036aeb4>] __dev_open+0xdc/0x150 [<c036b1b8>] __dev_change_flags+0xa0/0x174 [<c036b2ac>] dev_change_flags+0x20/0x60 Even though the issue was discovered in 4.9 kernel, the code in question is identical in the current net and net-next trees.
