2013-09-26of: Fix missing memory initialization on FDT unflatteningGrant Likely
commit 0640332e073be9207f0784df43595c0c39716e42 upstream. Any calls to dt_alloc() need to be zeroed. This is a temporary fix, but the allocation function itself needs to zero memory before returning it. This is a follow up to patch 9e4012752, "of: fdt: fix memory initialization for expanded DT" which fixed one call site but missed another.

2013-09-26mmc: tmio_mmc_dma: fix PIO fallback on SDHISergei Shtylyov
commit f936f9b67b7f8c2eae01dd303a0e90bd777c4679 upstream. I'm testing SH-Mobile SDHI driver in DMA mode with a new DMA controller using 'bonnie++' and getting DMA error after which the tmio_mmc_dma.c code falls back to PIO but all commands time out after that. It turned out that the fallback code calls tmio_mmc_enable_dma() with RX/TX channels already freed and pointers to them cleared, so that the function bails out early instead of clearing the DMA bit in the CTL_DMA_ENABLE register. The regression was introduced by commit 162f43e31c5a376ec16336e5d0ac973373d54c89 (mmc: tmio: fix a deadlock). Moving tmio_mmc_enable_dma() calls to the top of the PIO fallback code in tmio_mmc_start_dma_{rx|tx}() helps.

2013-09-26intel-iommu: Fix leaks in pagetable freeingAlex Williamson
commit 3269ee0bd6686baf86630300d528500ac5b516d7 upstream. At best the current code only seems to free the leaf pagetables and the root. If you're unlucky enough to have a large gap (like any QEMU guest with more than 3G of memory), only the first chunk of leaf pagetables are freed (plus the root). This is a massive memory leak. This patch re-writes the pagetable freeing function to use a recursive algorithm and manages to not only free all the pagetables, but does it without any apparent performance loss versus the current broken version.

2013-09-26usb: xhci: Disable runtime PM suspend for quirky controllersShawn Nematbakhsh
commit c8476fb855434c733099079063990e5bfa7ecad6 upstream. If a USB controller with XHCI_RESET_ON_RESUME goes to runtime suspend, a reset will be performed upon runtime resume. Any previously suspended devices attached to the controller will be re-enumerated at this time. This will cause problems, for example, if an open system call on the device triggered the resume (the open call will fail). Note that this change is only relevant when persist_enabled is not set for USB devices. This patch should be backported to kernels as old as 3.0, that contain the commit c877b3b2ad5cb9d4fe523c5496185cc328ff3ae9 "xhci: Add reset on resume quirk for asrock p67 host".

2013-09-26xhci-plat: Don't enable legacy PCI interrupts.Sarah Sharp
commit 52fb61250a7a132b0cfb9f4a1060a1f3c49e5a25 upstream. The xHCI platform driver calls into usb_add_hcd to register the irq for its platform device. It does not want the xHCI generic driver to register an interrupt for it at all. The original code did that by setting the XHCI_BROKEN_MSI quirk, which tells the xHCI driver to not enable MSI or MSI-X for a PCI host. Unfortunately, if CONFIG_PCI is enabled, and CONFIG_USB_DW3 is enabled, the xHCI generic driver will attempt to register a legacy PCI interrupt for the xHCI platform device in xhci_try_enable_msi(). This will result in a bogus irq being registered, since the underlying device is a platform_device, not a pci_device, and thus the pci_device->irq pointer will be bogus. Add a new quirk, XHCI_PLAT, so that the xHCI generic driver can distinguish between a PCI device that can't handle MSI or MSI-X, and a platform device that should not have its interrupts touched at all. This quirk may be useful in the future, in case other corner cases like this arise. This patch should be backported to kernels as old as 3.9, that contain the commit 00eed9c814cb8f281be6f0f5d8f45025dc0a97eb "USB: xhci: correctly enable interrupts".

2013-09-14macvtap: do not zerocopy if iov needs more pages than MAX_SKB_FRAGSJason Wang
commit ece793fcfc417b3925844be88a6a6dc82ae8f7c6 upstream. We try to linearize part of the skb when the number of iov is greater than MAX_SKB_FRAGS. This is not enough since each single vector may occupy more than one pages, so zerocopy_sg_fromiovec() may still fail and may break the guest network. Solve this problem by calculate the pages needed for iov before trying to do zerocopy and switch to use copy instead of zerocopy if it needs more than MAX_SKB_FRAGS. This is done through introducing a new helper to count the pages for iov, and call uarg->callback() manually when switching from zerocopy to copy to notify vhost. We can do further optimization on top. This bug were introduced from b92946e2919134ebe2a4083e4302236295ea2a73 (macvtap: zerocopy: validate vectors before building skb). Cc: Michael S.

2013-09-07ath9k_htc: Restore skb headroom when returning skb to mac80211Helmut Schaa
commit d2e9fc141e2aa21f4b35ee27072d84e9aa6e2ba0 upstream. ath9k_htc adds padding between the 802.11 header and the payload during TX by moving the header. When handing the frame back to mac80211 for TX status handling the header is not moved back into its original position. This can result in a too small skb headroom when entering ath9k_htc again (due to a soft retransmission for example) causing an skb_under_panic oops. Fix this by moving the 802.11 header back into its original position before returning the frame to mac80211 as other drivers like rt2x00 or ath5k do.

2013-09-07drivers/base/memory.c: fix show_mem_removable() to handle missing sectionsRuss Anderson
commit 21ea9f5ace3a7317cc3ba1fbc749758021a83136 upstream. "cat /sys/devices/system/memory/memory*/removable" crashed the system. The problem is that show_mem_removable() is passing a bad pfn to is_mem_section_removable(), which causes if (!node_online(page_to_nid(page))) to blow up. Why is it passing in a bad pfn? The reason is that show_mem_removable() will loop sections_per_block times. sections_per_block is 16, but mem->section_count is 8, indicating holes in this memory block. Checking that the memory section is present before checking to see if the memory section is removable fixes the problem. harp5-sys:~ # cat /sys/devices/system/memory/memory*/removable 0 1 1 1 1 1 1 1 1 1 1 1 1 1 BUG: unable to handle kernel paging request at ffffea00c3200000 IP: [<ffffffff81117ed1>] is_pageblock_removable_nolock+0x1/0x90 PGD 83ffd4067 PUD 37bdfce067 PMD 0 Oops: 0000 [#1] SMP Modules linked in: autofs4 binfmt_misc rdma_ucm rdma_cm iw_cm ib_addr ib_srp scsi_transport_srp scsi_tgt ib_ipoib ib_cm ib_uverbs ib_umad iw_cxgb3 cxgb3 mdio mlx4_en mlx4_ib ib_sa mlx4_core ib_mthca ib_mad ib_core fuse nls_iso8859_1 nls_cp437 vfat fat joydev loop hid_generic usbhid hid hwperf(O) numatools(O) dm_mod iTCO_wdt ipv6 iTCO_vendor_support igb i2c_i801 ioatdma i2c_algo_bit ehci_pci pcspkr lpc_ich i2c_core ehci_hcd ptp sg mfd_core dca rtc_cmos pps_core mperf button xhci_hcd sd_mod crc_t10dif usbcore usb_common scsi_dh_emc scsi_dh_hp_sw scsi_dh_alua scsi_dh_rdac scsi_dh gru(O) xvma(O) xfs crc32c libcrc32c thermal sata_nv processor piix mptsas mptscsih scsi_transport_sas mptbase megaraid_sas fan thermal_sys hwmon ext3 jbd ata_piix ahci libahci libata scsi_mod CPU: 4 PID: 5991 Comm: cat Tainted: G O 3.11.0-rc5-rja-uv+ #10 Hardware name: SGI UV2000/ROMLEY, BIOS SGI UV 2000/3000 series BIOS 01/15/2013 task: ffff88081f034580 ti: ffff880820022000 task.ti: ffff880820022000 RIP: 0010:[<ffffffff81117ed1>] [<ffffffff81117ed1>] is_pageblock_removable_nolock+0x1/0x90 RSP: 0018:ffff880820023df8 EFLAGS: 00010287 RAX: 0000000000040000 RBX: ffffea00c3200000 RCX: 0000000000000004 RDX: ffffea00c30b0000 RSI: 00000000001c0000 RDI: ffffea00c3200000 RBP: ffff880820023e38 R08: 0000000000000000 R09: 0000000000000001 R10: 0000000000000000 R11: 0000000000000001 R12: ffffea00c33c0000 R13: 0000160000000000 R14: 6db6db6db6db6db7 R15: 0000000000000001 FS: 00007ffff7fb2700(0000) GS:ffff88083fc80000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 CR2: ffffea00c3200000 CR3: 000000081b954000 CR4: 00000000000407e0 Call Trace: show_mem_removable+0x41/0x70 dev_attr_show+0x2a/0x60 sysfs_read_file+0xf7/0x1c0 vfs_read+0xc8/0x130 SyS_read+0x5d/0xa0 system_call_fastpath+0x16/0x1b Signed-off-by: Russ Anderson <rja@sgi.com> Cc: "Rafael J.

Unfortunately, execute_in_process_context() decides to immediately execute that device removal function, instead of scheduling asynchronous execution, since it detects process context and thinks it is safe to do so. But almost all calls to shost_for_each_device() in our lldd are inside spin_lock_irq, even in thread context. Obviously, schedule() inside spin_lock_irq sections is a bad idea. Change the lldd to use the proper iterator function, __shost_for_each_device(), in combination with required locking. Occurences that need to be changed include all calls in zfcp_erp.c, since those might be executed in zfcp error recovery thread context with a lock held. Other occurences of shost_for_each_device() in zfcp_fsf.c do not need to be changed (no process context, no surrounding locking). The problem was introduced in Linux 2.6.37 by commit b62a8d9b45b971a67a0f8413338c230e3117dff5 "[SCSI] zfcp: Use SCSI device data zfcp_scsi_dev instead of zfcp_unit".

2013-08-29SCSI: zfcp: fix lock imbalance by reworking request queue lockingMartin Peschke
commit d79ff142624e1be080ad8d09101f7004d79c36e1 upstream. This patch adds wait_event_interruptible_lock_irq_timeout(), which is a straight-forward descendant of wait_event_interruptible_timeout() and wait_event_interruptible_lock_irq(). The zfcp driver used to call wait_event_interruptible_timeout() in combination with some intricate and error-prone locking. Using wait_event_interruptible_lock_irq_timeout() as a replacement nicely cleans up that locking. This rework removes a situation that resulted in a locking imbalance in zfcp_qdio_sbal_get(): BUG: workqueue leaked lock or atomic: events/1/0xffffff00/10 last function: zfcp_fc_wka_port_offline+0x0/0xa0 [zfcp] It was introduced by commit c2af7545aaff3495d9bf9a7608c52f0af86fb194 "[SCSI] zfcp: Do not wait for SBALs on stopped queue", which had a new code path related to ZFCP_STATUS_ADAPTER_QDIOUP that took an early exit without a required lock being held. The problem occured when a special, non-SCSI I/O request was being submitted in process context, when the adapter's queues had been torn down. In this case the bug surfaced when the Fibre Channel port connection for a well-known address was closed during a concurrent adapter shut-down procedure, which is a rare constellation. This patch also fixes these warnings from the sparse tool (make C=1): drivers/s390/scsi/zfcp_qdio.c:224:12: warning: context imbalance in 'zfcp_qdio_sbal_check' - wrong count at exit drivers/s390/scsi/zfcp_qdio.c:244:5: warning: context imbalance in 'zfcp_qdio_sbal_get' - unexpected unlock Last but not least, we get rid of that crappy lock-unlock-lock sequence at the beginning of the critical section.

commit 9e40127526e857fa3f29d51e83277204fbdfc6ba upstream. Already existing property flags are filled wrong for properties created from initial FDT. This could cause problems if this DYNAMIC device-tree functions are used later, i.e. properties are attached/detached/replaced. Simply dumping flags from the running system show, that some initial static (not allocated via kzmalloc()) nodes are marked as dynamic. I putted some debug extensions to property_proc_show(..) : .. + if (OF_IS_DYNAMIC(pp)) + pr_err("DEBUG: xxx : OF_IS_DYNAMIC\n"); + if (OF_IS_DETACHED(pp)) + pr_err("DEBUG: xxx : OF_IS_DETACHED\n"); when you operate on the nodes (e.g.: ~$ cat /proc/device-tree/*some_node*) you will see that those flags are filled wrong, basically in most cases it will dump a DYNAMIC or DETACHED status, which is in not true. (BTW. this OF_IS_DETACHED is a own define for debug purposes which which just make a test_bit(OF_DETACHED, &x->_flags) If nodes are dynamic kernel is allowed to kfree() them. But it will crash attempting to do so on the nodes from FDT -- they are not allocated via kzmalloc().

2013-08-29drm/i915: Invalidate TLBs for the rings after a resetChris Wilson
commit 884020bf3d2a3787a1cc6df902e98e0eec60330b upstream. After any "soft gfx reset" we must manually invalidate the TLBs associated with each ring. Empirically, it seems that a suspend/resume or D3-D0 cycle count as a "soft reset". The symptom is that the hardware would fail to note the new address for its status page, and so it would continue to write the shadow registers and breadcrumbs into the old physical address (now used by something completely different, scary). Whereas the driver would read the new status page and never see any progress, it would appear that the GPU hung immediately upon resume.

commit 84ca7a8e45dafb49cd5ca90a343ba033e2885c17 upstream. The sizeof() argument in init_evtchn_cpu_bindings() is incorrect resulting in only the first 64 (or 32 in 32-bit guests) ports having their bindings being initialized to VCPU 0. In most cases this does not cause a problem as request_irq() will set the irq affinity which will set the correct local per-cpu mask. However, if the request_irq() is called on a VCPU other than 0, there is a window between the unmasking of the event and the affinity being set were an event may be lost because it is not locally unmasked on any VCPU. If request_irq() is called on VCPU 0 then local irqs are disabled during the window and the race does not occur. Fix this by initializing all NR_EVENT_CHANNEL bits in the local per-cpu masks.

2013-08-20USB: mos7720: fix broken control requestsJohan Hovold
commit ef6c8c1d733e244f0499035be0dabe1f4ed98c6f upstream. The parallel-port code of the drivers used a stack allocated control-request buffer for asynchronous (and possibly deferred) control requests. This not only violates the no-DMA-from-stack requirement but could also lead to corrupt control requests being submitted.

2013-08-20can: pcan_usb: fix wrong memcpy() bytes lengthStephane Grosjean
commit 3c322a56b01695df15c70bfdc2d02e0ccd80654e upstream. Fix possibly wrong memcpy() bytes length since some CAN records received from PCAN-USB could define a DLC field in range [9..15]. In that case, the real DLC value MUST be used to move forward the record pointer but, only 8 bytes max. MUST be copied into the data field of the struct can_frame object of the skb given to the network core.
