2016-06-06IB/core: fix null pointer deref and mem leak in error handlingColin Ian King
The current error handling in setup_hw_stats has a couple of issues. It is possible to generate a null pointer deference on the kfree of hsag->attrs[i] because two of the early error exit paths jump to the kfree when hsags NULL and not allocated. Fix this by moving the kfree on stats and jumping to that, avoiding the hsag freeing. Secondly, there is a memory leak of stats if the hsag allocation fails; instead of returning, jump to the kfree on stats.

2016-06-06drm/vc4: Make pageflip completion handling more robust.Mario Kleiner
Protect both the setup of the pageflip event and the latching of the new requested displaylist head pointer by the event lock, so we can't get into a situation where vc4_atomic_flush latches the new display list via HVS_WRITE, then immediately gets preempted before queueing the pageflip event, then the page-flip completes in hw and the vc4_crtc_handle_page_flip() runs and no-ops due to lack of a pending pageflip event, then vc4_atomic_flush continues and only then queues the pageflip event - after the page flip handling already no-oped. This would cause flip completion handling only at the next vblank - one frame too late. In vc4_crtc_handle_page_flip() check the actual DL head pointer in SCALER_DISPLACTX against the requested pointer for page flip to make sure that the flip actually really completed in the current vblank and doesn't get deferred to the next one because the DL head pointer was written a bit too late into SCALER_DISPLISTX, after start of vblank, and missed the boat. This avoids handling a pageflip completion too early - one frame too early. According to Eric, DL head pointer updates which were written into the HVS DISPLISTX reg get committed to hardware at the last pixel of active scanout. Our vblank interrupt handler, as triggered by PV_INT_VFP_START irq, gets to run earliest at the first pixel of HBLANK at the end of the last scanline of active scanout, ie. vblank irq handling runs at least 1 pixel duration after a potential pageflip completion happened in hardware. This ordering of events in the hardware, together with the lock protection and SCALER_DISPLACTX sampling of this patch, guarantees that pageflip completion handling only runs at exactly the vblank irq of actual pageflip completion in all cases. Background info from Eric about the relative timing of HVS, PV's and trigger points for interrupts, DL updates: https://lists.freedesktop.org/archives/dri-devel/2016-May/107510.html Tested on RPi 2B with hardware timing measurement equipment and shown to no longer complete flips too early or too late.

2016-06-06Btrfs: self-tests: Fix extent buffer bitmap test fail on BE systemFeifei Xu
In __test_eb_bitmaps(), we write random data to a bitmap. Then copy the bitmap to another bitmap that resides inside an extent buffer. Later we verify the values of corresponding bits in the bitmap and the bitmap inside the extent buffer. However, extent_buffer_test_bit() reads in byte granularity while test_bit() reads in unsigned long granularity. Hence we end up comparing wrong bits on big-endian systems such as ppc64. This commit fixes the issue by reading the bitmap in byte granularity.

2016-06-05bnx2x: allow adding VLANs while interface is downMichal Schmidt
Since implementing VLAN filtering in commit 05cc5a39ddb74 ("bnx2x: add vlan filtering offload") bnx2x refuses to add a VLAN while the interface is down: # ip link add link enp3s0f0 enp3s0f0_10 type vlan id 10 RTNETLINK answers: Bad address and in dmesg (with bnx2x.debug=0x20): bnx2x: [bnx2x_vlan_rx_add_vid:12941(enp3s0f0)]Ignoring VLAN configuration the interface is down Other drivers have no problem with this. Fix this peculiar behavior in the following way: - Accept requests to add/kill VID regardless of the device state. Maintain the requested list of VIDs in the bp->vlan_reg list. - If the device is up, try to configure the VID list into the hardware. If we run out of VLAN credits or encounter a failure configuring an entry, fall back to accepting all VLANs. If we successfully configure all entries from the list, turn the fallback off. - Use the same code for reconfiguring VLANs during NIC load.

2016-06-06powerpc/pseries: Fix PCI config address for DDWGavin Shan
In commit 8445a87f7092 "powerpc/iommu: Remove the dependency on EEH struct in DDW mechanism", the PE address was replaced with the PCI config address in order to remove dependency on EEH. According to PAPR spec, firmware (pHyp or QEMU) should accept "xxBBSSxx" format PCI config address, not "xxxxBBSS" provided by the patch. Note that "BB" is PCI bus number and "SS" is the combination of slot and function number. This fixes the PCI address passed to DDW RTAS calls.

2016-06-06ipvs: update real-server binding of outgoing connections in SIP-peMarco Angaroni
Previous patch that introduced handling of outgoing packets in SIP persistent-engine did not call ip_vs_check_template() in case packet was matching a connection template. Assumption was that real-server was healthy, since it was sending a packet just in that moment. There are however real-server fault conditions requiring that association between call-id and real-server (represented by connection template) gets updated. Here is an example of the sequence of events: 1) RS1 is a back2back user agent that handled call-id1 and call-id2 2) RS1 is down and was marked as unavailable 3) new message from outside comes to IPVS with call-id1 4) IPVS reschedules the message to RS2, which becomes new call handler 5) RS2 forwards the message outside, translating call-id1 to call-id2 6) inside pe->conn_out() IPVS matches call-id2 with existing template 7) IPVS does not change association call-id2 <-> RS1 8) new message comes from client with call-id2 9) IPVS reschedules the message to a real-server potentially different from RS2, which is now the correct destination This patch introduces ip_vs_check_template() call in the handling of outgoing packets for SIP-pe. And also introduces a second optional argument for ip_vs_check_template() that allows to check if dest associated to a connection template is the same dest that was identified as the source of the packet. This is to change the real-server bound to a particular call-id independently from its availability status: the idea is that it's more reliable, for in->out direction (where internal network can be considered trusted), to always associate a call-id with the last real-server that used it in one of its messages. Think about above sequence of events where, just after step 5, RS1 returns instead to be available. Comparison of dests is done by simply comparing pointers to struct ip_vs_dest; there should be no cases where struct ip_vs_dest keeps its memory address, but represent a different real-server in terms of ip-address / port.
