2016-03-08drm/radeon: Switch to drm_vblank_on/offDaniel Vetter
These should be functionally equivalent to the older per/post modeset functions, except that they block out drm_vblank_get right away. There's only the clock adjusting code (outside of pageflips) in readone which uses drm_vblank_get. But that code doesn't synchronize against concurrent modesets and instead handles any such races by waiting for the right vblank to arrive with a short timetout. The longer-term plan here is to switch all kms drivers to drm_vblank_on/off so that common code like pending event cleanup can be done there, while drm_vblank_pre/post_modeset will be purely drm internal for the old UMS ioctl. Note that with this patch Michel uncovered a bug in the dri3 implementation of the DDX (it does vblank waits when the pipe is off), which had to be fixed first.

2016-03-08drm: introduce pipe color correction propertiesLionel Landwerlin
Patch based on a previous series by Shashank Sharma. This introduces optional properties to enable color correction at the pipe level. It relies on 3 transformations applied to every pixels displayed. First a lookup into a degamma table, then a multiplication of the rgb components by a 3x3 matrix and finally another lookup into a gamma table. The following properties can be added to a pipe : - DEGAMMA_LUT : blob containing degamma LUT - DEGAMMA_LUT_SIZE : number of elements in DEGAMMA_LUT - CTM : transformation matrix applied after the degamma LUT - GAMMA_LUT : blob containing gamma LUT - GAMMA_LUT_SIZE : number of elements in GAMMA_LUT DEGAMMA_LUT_SIZE and GAMMA_LUT_SIZE are read only properties, set by the driver to tell userspace applications what sizes should be the lookup tables in DEGAMMA_LUT and GAMMA_LUT. A helper is also provided so legacy gamma correction is redirected through these new properties. v2: Register LUT size properties as range v3: Fix round in drm_color_lut_get_value() helper More docs on how degamma/gamma properties are used v4: Update contributors v5: Rename CTM_MATRIX property to CTM (Doh!)

2016-03-08KVM: s390: correct fprs on SIGP (STOP AND) STORE STATUSDavid Hildenbrand
With MACHINE_HAS_VX, we convert the floating point registers from the vector registeres when storing the status. For other VCPUs, these are stored to vcpu->run->s.regs.vrs, but we are using current->thread.fpu.vxrs, which resolves to the currently loaded VCPU. So kvm_s390_store_status_unloaded() currently writes the wrong floating point registers (converted from the vector registers) when called from another VCPU on a z13. This is only the case for old user space not handling SIGP STORE STATUS and SIGP STOP AND STORE STATUS, but relying on the kernel implementation. All other calls come from the loaded VCPU via kvm_s390_store_status().

2016-03-08KVM: VMX: disable PEBS before a guest entryRadim Krčmář
Linux guests on Haswell (and also SandyBridge and Broadwell, at least) would crash if you decided to run a host command that uses PEBS, like perf record -e 'cpu/mem-stores/pp' -a This happens because KVM is using VMX MSR switching to disable PEBS, but SDM [2015-12] 18.4.4.4 Re-configuring PEBS Facilities explains why it isn't safe: When software needs to reconfigure PEBS facilities, it should allow a quiescent period between stopping the prior event counting and setting up a new PEBS event. The quiescent period is to allow any latent residual PEBS records to complete its capture at their previously specified buffer address (provided by IA32_DS_AREA). There might not be a quiescent period after the MSR switch, so a CPU ends up using host's MSR_IA32_DS_AREA to access an area in guest's memory. (Or MSR switching is just buggy on some models.) The guest can learn something about the host this way: If the guest doesn't map address pointed by MSR_IA32_DS_AREA, it results in #PF where we leak host's MSR_IA32_DS_AREA through CR2. After that, a malicious guest can map and configure memory where MSR_IA32_DS_AREA is pointing and can therefore get an output from host's tracing. This is not a critical leak as the host must initiate with PEBS tracing and I have not been able to get a record from more than one instruction before vmentry in vmx_vcpu_run() (that place has most registers already overwritten with guest's). We could disable PEBS just few instructions before vmentry, but disabling it earlier shouldn't affect host tracing too much. We also don't need to switch MSR_IA32_PEBS_ENABLE on VMENTRY, but that optimization isn't worth its code, IMO. (If you are implementing PEBS for guests, be sure to handle the case where both host and guest enable PEBS, because this patch doesn't.)

2016-03-08drm/atomic: Handle encoder stealing from set_config better.Maarten Lankhorst
Instead of failing with -EINVAL when conflicting encoders are found, the legacy set_config will disable other connectors when encoders conflict. With the previous commit this becomes a lot easier to implement. set_config only adds connectors to the state that are modified, and because of the previous commit that calls add_affected_connectors only on set->crtc it means any connector not part of the modeset can be stolen from. We disable the connector in that case, and possibly the crtc if required. Atomic modeset itself still doesn't allow encoder stealing, the results would be too unpredictable.

2016-03-08KVM: PPC: Book3S HV: Sanitize special-purpose register values on guest exitPaul Mackerras
Thomas Huth discovered that a guest could cause a hard hang of a host CPU by setting the Instruction Authority Mask Register (IAMR) to a suitable value. It turns out that this is because when the code was added to context-switch the new special-purpose registers (SPRs) that were added in POWER8, we forgot to add code to ensure that they were restored to a sane value on guest exit. This adds code to set those registers where a bad value could compromise the execution of the host kernel to a suitable neutral value on guest exit.

Pull networking fixes from David Miller: 1) Fix ordering of WEXT netlink messages so we don't see a newlink after a dellink, from Johannes Berg. 2) Out of bounds access in minstrel_ht_set_best_prob_rage, from Konstantin Khlebnikov. 3) Paging buffer memory leak in iwlwifi, from Matti Gottlieb. 4) Wrong units used to set initial TCP rto from cached metrics, also from Konstantin Khlebnikov. 5) Fix stale IP options data in the SKB control block from leaking through layers of encapsulation, from Bernie Harris. 6) Zero padding len miscalculated in bnxt_en, from Michael Chan. 7) Only CHECKSUM_PARTIAL packets should be passed down through GSO, fix from Hannes Frederic Sowa. 8) Fix suspend/resume with JME networking devices, from Diego Violat and Guo-Fu Tseng. 9) Checksums not validated properly in bridge multicast support due to the placement of the SKB header pointers at the time of the check, fix from Álvaro Fernández Rojas. 10) Fix hang/tiemout with r8169 if a stats fetch is done while the device is runtime suspended. From Chun-Hao Lin. 11) The forwarding database netlink dump facilities don't track the state of the dump properly, resulting in skipped/missed entries. From Minoura Makoto. 12) Fix regression from a recent 3c59x bug fix, from Neil Horman. 13) Fix list corruption in bna driver, from Ivan Vecera. 14) Big endian machines crash on vlan add in bnx2x, fix from Michal Schmidt. 15) Ethtool RSS configuration not propagated properly in mlx5 driver, from Tariq Toukan. 16) Fix regression in PHY probing in stmmac driver, from Gabriel Fernandez. 17) Fix SKB tailroom calculation in igmp/mld code, from Benjamin Poirier. 18) A past change to skip empty routing headers in ipv6 extention header parsing accidently caused fragment headers to not be matched any longer. Fix from Florian Westphal. 19) eTSEC-106 erratum needs to be applied to more gianfar chips, from Atsushi Nemoto. 20) Fix netdev reference after free via workqueues in usb networking drivers, from Oliver Neukum and Bjørn Mork. 21) mdio->irq is now an array rather than a pointer to dynamic memory, but several drivers were still trying to free it :-/ Fixes from Colin Ian King. 22) act_ipt iptables action forgets to set the family field, thus LOG netfilter targets don't work with it. Fix from Phil Sutter. 23) SKB leak in ibmveth when skb_linearize() fails, from Thomas Falcon. 24) pskb_may_pull() cannot be called with interrupts disabled, fix code that tries to do this in vmxnet3 driver, from Neil Horman. 25) be2net driver leaks iomap'd memory on removal, fix from Douglas Miller. 26) Forgotton RTNL mutex unlock in ppp_create_interface() error paths, from Guillaume Nault. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: (97 commits) ppp: release rtnl mutex when interface creation fails cdc_ncm: do not call usbnet_link_change from cdc_ncm_bind tcp: fix tcpi_segs_in after connection establishment net: hns: fix the bug about loopback jme: Fix device PM wakeup API usage jme: Do not enable NIC WoL functions on S0 udp6: fix UDP/IPv6 encap resubmit path be2net: Don't leak iomapped memory on removal. vmxnet3: avoid calling pskb_may_pull with interrupts disabled net: ethernet: Add missing MFD_SYSCON dependency on HAS_IOMEM ibmveth: check return of skb_linearize in ibmveth_start_xmit cdc_ncm: toggle altsetting to force reset before setup usbnet: cleanup after bind() in probe() mlxsw: pci: Correctly determine if descriptor queue is full mlxsw: spectrum: Always decrement bridge's ref count tipc: fix nullptr crash during subscription cancel net: eth: altera: do not free array priv->mdio->irq net/ethoc: do not free array priv->mdio->irq net: sched: fix act_ipt for LOG target asix: do not free array priv->mdio->irq ...
