2016-03-07Revert "drm/radeon: call hpd_irq_event on resume"Linus Torvalds1-1/+0
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. I don't see an easy fix unless Dave has any ideas. I'd say just revert for now" Reported-by: Jörg-Volker Peetz <jvpeetz@web.de> Acked-by: Alexander Deucher <Alexander.Deucher@amd.com> Cc: Dave Airlie <airlied@gmail.com> Cc: stable@kernel.org # wherever dbb17a21c131 got back-ported Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

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 ... Fix it by splitting vmxnet3_parse_and_copy_hdr into two functions: vmxnet3_parse_hdr, which sets up the internal/on stack ctx datastructure, and pulls the skb (both of which can be done without holding the spinlock with irqs disabled and vmxnet3_copy_header, which just copies the skb to the tx ring under the lock safely. tested and shown to correct the described problem.

2016-03-07cdc_ncm: toggle altsetting to force reset before setupBjørn Mork1-1/+5
Some devices will silently fail setup unless they are reset first. This is necessary even if the data interface is already in altsetting 0, which it will be when the device is probed for the first time. Briefly toggling the altsetting forces a function reset regardless of the initial state. This fixes a setup problem observed on a number of Huawei devices, appearing to operate in NTB-32 mode even if we explicitly set them to NTB-16 mode.

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.

2016-03-07mlxsw: spectrum: Always decrement bridge's ref countIdo Schimmel1-3/+1
Since we only support one VLAN filtering bridge we need to associate a reference count with it, so that when the last port netdev leaves it, we would know that a different bridge can be offloaded to hardware. When a LAG device is memeber in a bridge and port netdevs are leaving the LAG, we should always decrement the bridge's reference count, as it's incremented for any port in the LAG.

commit 4d5cfcba2f6e ('tipc: fix connection abort during subscription cancel'), removes the check for a valid subscription before calling tipc_nametbl_subscribe().

Commit db2f24dc240856fb1d78005307f1523b7b3c121b was plain wrong. I did not realize the we are allowed to loop here. In fact we have to loop and must not return to userspace before all SIGSEGVs have been delivered. Other archs do this directly in their entry code, UML does it here.

The KVM/QEMU enabling for NVDIMMs has recently reached the point where it is able to accept some ACPI _DSM requests from a guest VM. However they immediately found that the 4.5-rc kernel is unusable because the kernel's 'nfit' driver fails to load upon seeing a valid "not supported" response from the virtual BIOS for an address range scrub command. It is not mandatory that a platform implement address range scrubbing, so this fix from Vishal properly treats the 'not supported' response as 'skip scrubbing and continue loading the driver'" * 'libnvdimm-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm: nfit: Continue init even if ARS commands are unimplemented

This touches both NVMe, and the block core since that is now generally utilized also for these types of commands. - Hot removal fixes. - User exploitable issue with passthrough IO commands, if !length is given, causing us to fault on writing to the zero page. - Fix for a hang under error conditions - And finally, the current series regression for umount with cgroup writeback, where the final flush would happen async and hence open up window after umount where the device wasn't consistent. fsck right after umount would show this.
