2015-10-14PM / Domains: Fix validation of latency constraints in genpd governorUlf Hansson
Commit ba2bbfbf6307 (PM / Domains: Remove intermediate states from the power off sequence) changed the power off sequence in genpd. That also required some updates regarding the validation of latency constraints in the genpd governor. Unfortunate that wasn't covered, so let's fix this. From a runtime PM and latency point of view, we need to consider the worst case scenario while validating latency constraints. That's typically when a call to pm_runtime_get_sync() needs to wait for a ongoing runtime suspend operation to be carried out, as it then also needs to wait for the device to be runtime resumed again. The above mentioned commit made the genpd governor's ->stop_ok() callback responsible of validating genpd's device's runtime suspend/resume latency. In other words, the constraint needs to be validated towards the relevant latencies present in genpd's ->runtime_suspend|resume() callbacks. Earlier, that included latencies from the ->stop|start() callbacks, but as ->save|restore_state() are now also being invoked from genpd's ->runtime_suspend|resume() and to comply with the worst case scenario, let's take also those latencies into account.

2015-10-13iommu/vt-d: fix range computation when making room for large pagesChristian Zander
In preparation for the installation of a large page, any small page tables that may still exist in the target IOV address range are removed. However, if a scatter/gather list entry is large enough to fit more than one large page, the address space for any subsequent large pages is not cleared of conflicting small page tables. This can cause legitimate mapping requests to fail with errors of the form below, potentially followed by a series of IOMMU faults: ERROR: DMA PTE for vPFN 0xfde00 already set (to 7f83a4003 not 7e9e00083) In this example, a 4MiB scatter/gather list entry resulted in the successful installation of a large page @ vPFN 0xfdc00, followed by a failed attempt to install another large page @ vPFN 0xfde00, due to the presence of a pointer to a small page table @ 0x7f83a4000. To address this problem, compute the number of large pages that fit into a given scatter/gather list entry, and use it to derive the last vPFN covered by the large page(s).

This breaks SMM with EPT but without unrestricted guest support, because the SMM copy of the identity page map is all zeros.

2015-10-13ipv6: Don't call with rt6_uncached_list_flush_devEric W. Biederman
As originally written rt6_uncached_list_flush_dev makes no sense when called with dev == NULL as it attempts to flush all uncached routes regardless of network namespace when dev == NULL. Which is simply incorrect behavior. Furthermore at the point rt6_ifdown is called with dev == NULL no more network devices exist in the network namespace so even if the code in rt6_uncached_list_flush_dev were to attempt something sensible it would be meaningless. Therefore remove support in rt6_uncached_list_flush_dev for handling network devices where dev == NULL, and only call rt6_uncached_list_flush_dev when rt6_ifdown is called with a network device.

Sathya Perla says: ==================== be2net: patch set Patch 1 fixes a FW image compatibility check in the driver that prevents certain FW images from being flashed on BE3 (not BE3-R) adapters. Patch 2 fixes a spin_lock not being released in a failure case in be_cmd_notify_wait(). Patch 3 includes a workaround to pad packets that are only 32b long or less to be applicabe to BE3 too. This workaround was currently applied only to Skyhawk and Lancer chips. Such packets are causing BE3's TX path to stall on a SR-IOV config. Patch 4 fixes the be_cmd_get_profile_config() routine to set the pf_num field in the cmd request. The FW requires this field to be set for it to return the specific function's descriptors. If not set, the FW returns the descriptors of all the functions on the device. If the first descriptor is not what is being queried for, the driver will read wrong data. This patch fixes this issue by using the GET_CNTL_ATTRIB cmd to query the real pci_func_num of a function and then uses it in the GET_PROFILE_CONFIG cmd. Patch 5 completes an earlier fix that removed the vlan promisc capability for VFs. The earlier fix did not update the removal of this capability from the profile descriptor of the VF. This causes the VF driver to request this capability when it tries to create it's interface at probe time. This could potentailly cause the VF probe to fail if the FW enforces strict checking of the flags based on what was provisoned by the PF. This strict checking is not being done by FW currently but will be fixed in a future version. This patch fixes this issue by updating the VF's profile descriptor so that they match the interface capability flags provisioned by the PF. Pls consider adding these patches to the net tree.

2015-10-13net/fsl_pq_mdio: fix computed address for the TBI registerGerlando Falauto
commit afae5ad78b342f401c28b0bb1adb3cd494cb125a "net/fsl_pq_mdio: streamline probing of MDIO nodes" added support for different types of MDIO devices: 1) Gianfar MDIO nodes that only map the MII registers 2) Gianfar MDIO nodes that map the full MDIO register set 3) eTSEC2 MDIO nodes (which map the full MDIO register set) 4) QE MDIO nodes (which map only the MII registers) However, the implementation for types 1 and 4 would mistakenly assume a mapping of the full MDIO register set, thereby computing the address for the TBI register starting from the containing structure. The TBI register would therefore be accessed at a wrong (much bigger) address, not giving the expected result at all. This patch restores the correct behavior we had prior to the above one. The consequences of this bug are apparent when trying to access a PHY with the same address as the value contained in the initial value of the TBI register (normally 0); in that case you'll get answers from the internal TBI device (even though MDIO/MDC pins are actually *also* toggling on the physical bus!). Beware that you also need to add a fake tbi node to your device tree with an unused address. Notice how this fix is related to commit 220669495bf8b68130a8218607147c7b74c28d2b "powerpc: Add TBI PHY node to first MDIO bus" which fixed the behavior in kernel 3.3, which was later broken by the above commit on kernel 3.7.

2015-10-12svcrdma: Fix NFS server crash triggered by 1MB NFS WRITEChuck Lever
Now that the NFS server advertises a maximum payload size of 1MB for RPC/RDMA again, it crashes in svc_process_common() when NFS client sends a 1MB NFS WRITE on an NFS/RDMA mount. The server has set up a 259 element array of struct page pointers in rq_pages[] for each incoming request. The last element of the array is NULL. When an incoming request has been completely received, rdma_read_complete() attempts to set the starting page of the incoming page vector: rqstp->rq_arg.pages = &rqstp->rq_pages[head->hdr_count]; and the page to use for the reply: rqstp->rq_respages = &rqstp->rq_arg.pages[page_no]; But the value of page_no has already accounted for head->hdr_count. Thus rq_respages now points past the end of the incoming pages. For NFS WRITE operations smaller than the maximum, this is harmless. But when the NFS WRITE operation is as large as the server's max payload size, rq_respages now points at the last entry in rq_pages, which is NULL. Fixes: cc9a903d915c ('svcrdma: Change maximum server payload . . .')
