This reverts commit dbb17a21c131eca94eb31136eee9a7fe5aff00d9. It turns out that commit can cause problems for systems with multiple GPUs, and causes X to hang on at least a HP Pavilion dv7 with hybrid graphics. This got noticed originally in 4.4.4, where this patch had already gotten back-ported, but 4.5-rc7 was verified to have the same problem. Alexander Deucher says: "It looks like you have a muxed system so I suspect what's happening is that one of the display is being reported as connected for both the IGP and the dGPU and then the desktop environment gets confused or there some sort problem in the detect functions since the mux is not switched to the dGPU.

2016-03-07hv_netvsc: Move subchannel waiting to rndis_filter_device_remove()Haiyang Zhang1-6/+13
During hot add, vmbus_device_register() is called from vmbus_onoffer(), on the same workqueue as the subchannel offer message work-queue, so subchannel offer won't be processed until the vmbus_device_register()/... /netvsc_probe() is done. Also, vmbus_device_register() is called with channel_mutex locked, which prevents subchannel processing too. So the "waiting for sub-channel processing" will not success in hot add case. But, in usual module loading, the netvsc_probe() is called from different code path, and doesn't fail. This patch resolves the deadlock during NIC hot-add, and speeds up NIC loading time.

2016-03-07udp6: fix UDP/IPv6 encap resubmit pathBill Sommerfeld1-4/+2
IPv4 interprets a negative return value from a protocol handler as a request to redispatch to a new protocol. In contrast, IPv6 interprets a negative value as an error, and interprets a positive value as a request for redispatch. UDP for IPv6 was unaware of this difference. Change __udp6_lib_rcv() to return a positive value for redispatch. Note that the socket's encap_rcv hook still needs to return a negative value to request dispatch, and in the case of IPv6 packets, adjust IP6CB(skb)->nhoff to identify the byte containing the next protocol.

2016-03-07vmxnet3: avoid calling pskb_may_pull with interrupts disabledNeil Horman1-27/+46
vmxnet3 has a function vmxnet3_parse_and_copy_hdr which, among other operations, uses pskb_may_pull to linearize the header portion of an skb. That operation eventually uses local_bh_disable/enable to ensure that it doesn't race with the drivers bottom half handler. Unfortunately, vmxnet3 preforms this parse_and_copy operation with a spinlock held and interrupts disabled. This causes us to run afoul of the WARN_ON_ONCE(irqs_disabled()) warning in local_bh_enable, resulting in this: WARNING: at kernel/softirq.c:159 local_bh_enable+0x59/0x90() (Not tainted) Hardware name: VMware Virtual Platform Modules linked in: ipv6 ppdev parport_pc parport microcode e1000 vmware_balloon vmxnet3 i2c_piix4 sg ext4 jbd2 mbcache sd_mod crc_t10dif sr_mod cdrom mptspi mptscsih mptbase scsi_transport_spi pata_acpi ata_generic ata_piix vmwgfx ttm drm_kms_helper drm i2c_core dm_mirror dm_region_hash dm_log dm_mod [last unloaded: mperf] Pid: 6229, comm: sshd Not tainted 2.6.32-616.el6.i686 #1 Call Trace: [<c04624d9>] ? warn_slowpath_common+0x89/0xe0 [<c0469e99>] ? local_bh_enable+0x59/0x90 [<c046254b>] ? warn_slowpath_null+0x1b/0x20 [<c0469e99>] ? local_bh_enable+0x59/0x90 [<c07bb936>] ? skb_copy_bits+0x126/0x210 [<f8d1d9fe>] ? ext4_ext_find_extent+0x24e/0x2d0 [ext4] [<c07bc49e>] ? __pskb_pull_tail+0x6e/0x2b0 [<f95a6164>] ? vmxnet3_xmit_frame+0xba4/0xef0 [vmxnet3] [<c05d15a6>] ? selinux_ip_postroute+0x56/0x320 [<c0615988>] ? cfq_add_rq_rb+0x98/0x110 [<c0852df8>] ? packet_rcv+0x48/0x350 [<c07c5839>] ? dev_queue_xmit_nit+0xc9/0x140 ...

2016-03-07mlxsw: pci: Correctly determine if descriptor queue is fullIdo Schimmel1-1/+1
The descriptor queues for sending (SDQs) and receiving (RDQs) packets are managed by two counters - producer and consumer - which are both 16-bit in size. A queue is considered full when the difference between the two equals the queue's maximum number of descriptors. However, if the producer counter overflows, then it's possible for the full queue check to fail, as it doesn't take the overflow into account. In such a case, descriptors already passed to the device - but for which a completion has yet to be posted - will be overwritten, thereby causing undefined behavior. The above can be achieved under heavy load (~30 netperf instances). Fix that by casting the subtraction result to u16, preventing it from being treated as a signed integer.

2016-03-07tipc: remove pre-allocated message header in link structJon Paul Maloy5-77/+45
Until now, we have kept a pre-allocated protocol message header aggregated into struct tipc_link. Apart from adding unnecessary footprint to the link instances, this requires extra code both to initialize and re-initialize it. We now remove this sub-optimization. This change also makes it possible to clean up the function tipc_build_proto_msg() and remove a couple of small functions that were accessing the mentioned header. In particular, we can replace all occurrences of the local function call link_own_addr(link) with the generic tipc_own_addr(net).

The netlink policy for TIPC_NLA_UDP_LOCAL and TIPC_NLA_UDP_REMOTE is of type binary with a defined length. This causes the policy framework to threat the defined length as maximum length. There is however no protection against a user sending a smaller amount of data. Prior to this patch this wasn't handled which could result in a partially incomplete sockaddr_storage struct containing uninitialized data. In this patch we use nla_memcpy() when copying the user data. This ensures a potential gap at the end is cleared out properly. This was found by Julia with Coccinelle tool.

2016-03-07tipc: don't check link reset on non existing linkRichard Alpe1-1/+1
Make sure we have a link before checking if it has been reset or not. Prior to this patch tipc_link_is_reset() could be called with a non existing link, resulting in a null pointer dereference.

2016-03-07tipc: add net device to skb before UDP xmitRichard Alpe1-0/+2
Prior to this patch enabling a IPv4 UDP bearer caused a null pointer dereference in iptunnel_xmit_stats(), when it tried to dereference the net device from the skb. To resolve this we now point the skb device to the net device resolved from the routing table.

Turns out the USB support for a Renesas board was developed on a pre-release board that ended up being changed before shipping. To avoid breakage on those boards, and avoid confusion, it's a reasonable idea to patch now instead of later.
