commit 6e522422 upstream. The VF administrative mac addresses (stored in the PF driver) are initialized to zero when the PF driver starts up. These addresses may be modified in the PF driver through ndo calls initiated by iproute2 or libvirt. While we allow the PF/host to change the VF admin mac address from zero to a valid unicast mac, we do not allow restoring the VF admin mac to zero. We currently only allow changing this mac to a different unicast mac. This leads to problems when libvirt scripts are used to deal with VF mac addresses, and libvirt attempts to revoke the mac so this host will not use it anymore. Fix this by allowing resetting a VF administrative MAC back to zero. Fixes: 8f7ba3ca ('net/mlx4: Add set VF mac address support') Signed-off-by:

commit 7099e2e1 upstream. 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.) Fixes: 26a4f3c0 ("perf/x86: disable PEBS on a guest entry.")

commit ccec4456 upstream. 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. Fixes: b005255eReported-by:

commit 256faedc upstream. This reverts commit dbb17a21. 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:

commit 7f54ab5f upstream. This patch fixes a recent ABORT_TASK regression associated with commit febe562c, where a left-over target_put_sess_cmd() would still be called when __target_check_io_state() detected a command has already been completed, and explicit ABORT must be avoided. Note commit febe562c dropped the local kref_get_unless_zero() check in core_tmr_abort_task(), but did not drop this extra corresponding target_put_sess_cmd() in the failure path. So go ahead and drop this now bogus target_put_sess_cmd(), and avoid this potential use-after-free. Reported-by:

commit e9a2d81b upstream. gs_destroy_candev() erroneously calls kfree() on a struct gs_can *, which is allocated through alloc_candev() and should instead be freed using free_candev() alone. The inappropriate use of kfree() causes the kernel to hang when gs_destroy_candev() is called. Only the struct gs_usb * which is allocated through kzalloc() should be freed using kfree() when the device is disconnected. Signed-off-by:

commit 7a36b930 upstream. The value 5000 was put here with the addition of the timeout field to ieee80211_start_tx_ba_session. It was originally added in mac80211 to save resources for drivers like iwlwifi, which only supports a limited number of concurrent aggregation sessions. Since iwlwifi does not use minstrel_ht and other drivers don't need this, 0 is a better default - especially since there have been recent reports of aggregation setup related issues reproduced with ath9k. This should improve stability without causing any adverse effects. Acked-by:

commit cb150b9d upstream. Since cfg80211 frequently takes actions from its netdev notifier call, wireless extensions messages could still be ordered badly since the wext netdev notifier, since wext is built into the kernel, runs before the cfg80211 netdev notifier. For example, the following can happen: 5: wlan1: <BROADCAST,MULTICAST> mtu 1500 qdisc mq state DOWN group default link/ether 02:00:00:00:01:00 brd ff:ff:ff:ff:ff:ff 5: wlan1: <BROADCAST,MULTICAST,UP> link/ether when setting the interface down causes the wext message. To also fix this, export the wireless_nlevent_flush() function and also call it from the cfg80211 notifier. Signed-off-by:

commit 8bf86273 upstream. Beniamino reported that he was getting an RTM_NEWLINK message for a given interface, after the RTM_DELLINK for it. It turns out that the message is a wireless extensions message, which was sent because the interface had been connected and disconnection while it was deleted caused a wext message. For its netlink messages, wext uses RTM_NEWLINK, but the message is without all the regular rtnetlink attributes, so "ip monitor link" prints just rudimentary information: 5: wlan1: <BROADCAST,MULTICAST> mtu 1500 qdisc mq state DOWN group default link/ether 02:00:00:00:01:00 brd ff:ff:ff:ff:ff:ff Deleted 5: wlan1: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN group default link/ether 02:00:00:00:01:00 brd ff:ff:ff:ff:ff:ff 5: wlan1: <BROADCAST,MULTICAST,UP> link/ether (from my hwsim reproduction) This can cause userspace to get confused since it doesn't expect an RTM_NEWLINK message after RTM_DELLINK. The reason for this is that wext schedules a worker to send out the messages, and the scheduling delay can cause the messages to get out to userspace in different order. To fix this, have wext register a netdevice notifier and flush out any pending messages when netdevice state changes. This fixes any ordering whenever the original message wasn't sent by a notifier itself. Reported-by:

commit b26a719b upstream. The R-Car GPIO driver handles Runtime PM for requested GPIOs only. When using a GPIO purely as an interrupt source, no Runtime PM handling is done, and the GPIO module's clock may not be enabled. To fix this: - Add .irq_request_resources() and .irq_release_resources() callbacks to handle Runtime PM when an interrupt is requested, - Add irq_bus_lock() and sync_unlock() callbacks to handle Runtime PM when e.g. disabling/enabling an interrupt, or configuring the interrupt type.

commit 197b958c upstream. The OSS sequencer client tries to drain the pending events at releasing. Unfortunately, as spotted by syzkaller fuzzer, this may lead to an unkillable process state when the event has been queued at the far future. Since the process being released can't be signaled any longer, it remains and waits for the echo-back event in that far future. Back to history, the draining feature was implemented at the time we misinterpreted POSIX definition for blocking file operation. Actually, such a behavior is superfluous at release, and we should just release the device as is instead of keeping it up forever. This patch just removes the draining call that may block the release for too long time unexpectedly.

commit deb7deff upstream. When opening a file, SMB2_open() attempts to parse the lease state from the SMB2 CREATE Response. However, the parsing code was not careful to ensure that the create contexts are not empty or invalid, which can lead to out- of-bounds memory access. This can be seen easily by trying to read a file from a OSX 10.11 SMB3 server.

commit b24e7ad1 upstream. X32 ABI takes the 64bit timespec, thus the timer user status ioctl becomes incompatible with IA32. This results in NOTTY error when the ioctl is issued. Meanwhile, this struct in X32 is essentially identical with the one in X86-64, so we can just bypassing to the existing code for this specific compat ioctl. Signed-off-by:

commit 3a72494a upstream. The timer user status compat ioctl returned the bogus struct used for 64bit architectures instead of the 32bit one. This patch addresses it to return the proper struct. Signed-off-by:

commit 2251fbbc upstream. Like the previous fixes for ctl and PCM, we need a fix for incompatible X32 ABI regarding the rawmidi: namely, struct snd_rawmidi_status has the timespec, and the size and the alignment on X32 differ from IA32. This patch fixes the incompatible ioctl for X32. Signed-off-by:

commit 6236d8bb upstream. The X32 ABI takes the same alignment like x86-64, and this may result in the incompatible struct size from ia32. Unfortunately, we hit this in some control ABI: struct snd_ctl_elem_value differs between them due to the position of 64bit variable array. This ends up with the unknown ioctl (ENOTTY) error. The fix is to add the compat entries for the new aligned struct. Reported-and-tested-by:
