2013-08-23usb: fix cleanup after failure in hub_configure()Krzysztof Mazur
If the hub_configure() fails after setting the hdev->maxchild the hub->ports might be NULL or point to uninitialized kzallocated memory causing NULL pointer dereference in hub_quiesce() during cleanup. Now after such error the hdev->maxchild is set to 0 to avoid cleanup of uninitialized ports.

Commit 7e8d5cd93fac ("USB: Add EHCI support for MX27 and MX31 based boards") introduced code that could potentially lead to a NULL pointer dereference on driver removal. Fix this by checking for the value of pdata before dereferencing it.

ra.kernel.org:/pub/scm/linux/kernel/git/sarah/xhci into work-next Sarah writes: xhci: Step 2 to fix usb-linus and usb-next. Hi Greg, This is the first of two steps to fix your usb-linus and usb-next trees. As I mentioned, commit 4fae6f0fa86f92e6bc7429371b1e177ad0aaac66 "USB: handle LPM errors during device suspend correctly" was incorrectly added to usb-next when it should have been added to usb-linus and marked for stable. Two port power off bug fixes touch the same code that patch touches, but it's not easy to simply move commit 4fae6f0f patch to usb-linus because commit 28e861658e23ca94692f98e245d254c75c8088a7 "USB: refactor code for enabling/disabling remote wakeup" also touched those code sections. I propose a two step process to fix this: 1. Pull these four patches into usb-linus. 2. Revert commit 28e861658e23ca94692f98e245d254c75c8088a7 from usb-next. Merge usb-linus into usb-next, and resolve the conflicts. I will be sending pull requests for these steps. This pull request is step two. Sarah Sharp

2013-08-16jbd2: Fix oops in jbd2_journal_file_inode()Jan Kara
Commit 0713ed0cde76438d05849f1537d3aab46e099475 added jbd2_journal_file_inode() call into ext4_block_zero_page_range(). However that function gets called from truncate path and thus inode needn't have jinode attached - that happens in ext4_file_open() but the file needn't be ever open since mount. Calling jbd2_journal_file_inode() without jinode attached results in the oops. We fix the problem by attaching jinode to inode also in ext4_truncate() and ext4_punch_hole() when we are going to zero out partial blocks.

2013-08-16Fix TLB gather virtual address range invalidation corner casesLinus Torvalds
Ben Tebulin reported: "Since v3.7.2 on two independent machines a very specific Git repository fails in 9/10 cases on git-fsck due to an SHA1/memory failures. This only occurs on a very specific repository and can be reproduced stably on two independent laptops. Git mailing list ran out of ideas and for me this looks like some very exotic kernel issue" and bisected the failure to the backport of commit 53a59fc67f97 ("mm: limit mmu_gather batching to fix soft lockups on !CONFIG_PREEMPT"). That commit itself is not actually buggy, but what it does is to make it much more likely to hit the partial TLB invalidation case, since it introduces a new case in tlb_next_batch() that previously only ever happened when running out of memory. The real bug is that the TLB gather virtual memory range setup is subtly buggered. It was introduced in commit 597e1c3580b7 ("mm/mmu_gather: enable tlb flush range in generic mmu_gather"), and the range handling was already fixed at least once in commit e6c495a96ce0 ("mm: fix the TLB range flushed when __tlb_remove_page() runs out of slots"), but that fix was not complete. The problem with the TLB gather virtual address range is that it isn't set up by the initial tlb_gather_mmu() initialization (which didn't get the TLB range information), but it is set up ad-hoc later by the functions that actually flush the TLB. And so any such case that forgot to update the TLB range entries would potentially miss TLB invalidates. Rather than try to figure out exactly which particular ad-hoc range setup was missing (I personally suspect it's the hugetlb case in zap_huge_pmd(), which didn't have the same logic as zap_pte_range() did), this patch just gets rid of the problem at the source: make the TLB range information available to tlb_gather_mmu(), and initialize it when initializing all the other tlb gather fields. This makes the patch larger, but conceptually much simpler. And the end result is much more understandable; even if you want to play games with partial ranges when invalidating the TLB contents in chunks, now the range information is always there, and anybody who doesn't want to bother with it won't introduce subtle bugs. Ben verified that this fixes his problem.

Hi Greg, This pull request includes one new feature for the xhci-plat driver (device tree support). Felipe was fine with the patch last I checked, but hadn't provided an official Acked-by line. This pull request also includes 13 patches from my FOSS Outreach Program for Women (OPW) intern, Xenia. She fixed a bug in the xHCI driver so that the driver can allocate 64-bit consistent DMA, converted the driver to use dynamic debugging, and added a bunch of new trace events for the xHCI driver. The python plugin for trace-cmd should be up on git hub shortly, although the trace events are usable without it. I'm very happy with the progress that Xenia has made, and I look forward to her future contributions to the Linux kernel. Sarah Sharp
2013-08-15net/mlx5_core: Support MANAGE_PAGES and QUERY_PAGES firmware command changesMoshe Lazer
In the previous QUERY_PAGES command version we used one command to get the required amount of boot, init and post init pages. The new version uses the op_mod field to specify whether the query is for the required amount of boot, init or post init pages. In addition the output field size for the required amount of pages increased from 16 to 32 bits. In MANAGE_PAGES command the input_num_entries and output_num_entries fields sizes changed from 16 to 32 bits and the PAS tables offset changed to 0x10. In the pages request event the num_pages field also changed to 32 bits. In the HCA-capabilities-layout the size and location of max_qp_mcg field has been changed to support 24 bits. This patch isn't compatible with firmware versions < 5; however, it turns out that the first GA firmware we will publish will not support previous versions so this should be OK.

2013-08-15net: tg3: fix NULL pointer dereference in tg3_io_error_detected and ↵Daniel Borkmann
tg3_io_slot_reset Commit d8af4dfd8 ("net/tg3: Fix kernel crash") introduced a possible NULL pointer dereference in tg3 driver when !netdev || !netif_running(netdev) condition is met and netdev is NULL. Then, the jump to the 'done' label calls dev_close() with a netdevice that is NULL. Therefore, only call dev_close() when we have a netdevice, but one that is not running.

2013-08-15xhci-plat: Don't enable legacy PCI interrupts.Sarah Sharp
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".

2013-08-15usb: Don't fail port power resume on device disconnect.Sarah Sharp
Userspace can tell the kernel to power off any USB port, including ones that are visible and connectible to users. When an attached USB device goes into suspend, the port will be powered off if the pm_qos_no_port_poweroff file for its port is set to 0, the device does not have remote wakeup enabled, and the device is marked as persistent. If the user disconnects the USB device while the port is powered off, the current code does not handle that properly. If you disconnect a device, and then run `lsusb -v -s` for the device, the device disconnect does not get handled by the USB core. The runtime resume of the port fails, because hub_port_debounce_be_connected() returns -ETIMEDOUT. This means the port resume fails and khubd doesn't handle the USB device disconnect. This leaves the device listed in lsusb, and the port's runtime_status will be permanently marked as "error". Fix this by ignoring the return value of hub_port_debounce_be_connected. Users can disconnect USB devices while the ports are powered off, and we must be able to handle that. This patch should be backported to kernels as old as 3.9, that contain the commit ad493e5e580546e6c3024b76a41535476da1546a "usb: add usb port auto power off mechanism" Signed-off-by: Sarah Sharp <sarah.a.sharp@linux.intel.com> Cc: Lan Tianyu <tianyu.lan@intel.com> Cc: Alan Stern <stern@rowland.harvard.edu> Cc: Rafael J.

2013-08-15usb: don't check pm qos NO_POWER_OFF flag in usb_port_suspend()Lan Tianyu
The pm qos NO_POWER_OFF flag is checked twice during usb device suspend to see if the usb port power off condition is met. This is redundant and also will prevent the port from being powered off if the NO_POWER_OFF flag is changed to 1 from 0 after the device was already suspended. More detail in the following link. http://marc.info/?l=linux-usb&m=136543949130865&w=2 This patch should be backported to kernels as old as 3.7, that contain the commit f7ac7787ad361e31a7972e2854ed8dc2eedfac3b "usb/acpi: Use ACPI methods to power off ports."

2013-08-15USB: handle LPM errors during device suspend correctlyAlan Stern
The hub driver's usb_port_suspend() routine doesn't handle errors related to Link Power Management properly. It always returns failure, it doesn't try to clean up the wakeup setting, (in the case of system sleep) it doesn't try to go ahead with the port suspend regardless, and it doesn't try to apply the new power-off mechanism. This patch fixes these problems. Note: Sarah fixed this patch to apply against 3.11, since the original commit (4fae6f0fa86f92e6bc7429371b1e177ad0aaac66 "USB: handle LPM errors during device suspend correctly") called usb_disable_remote_wakeup, which won't be added until 3.12. This patch should be backported to kernels as old as 3.5, that contain the commit 8306095fd2c1100e8244c09bf560f97aca5a311d "USB: Disable USB 3.0 LPM in critical sections.". There will be merge conflicts, since LTM wasn't added until 3.6.

2013-08-15ASoC: tegra: fix Tegra30 I2S capture parameter setupStephen Warren
The Tegra30 I2S driver was writing the AHUB interface parameters to the playback path register rather than the capture path register. This caused the capture parameters not to be configured at all, so if capturing using non-HW-default parameters (e.g. 16-bit stereo rather than 8-bit mono) the audio would be corrupted. With this fixed, audio capture from an analog microphone works correctly on the Cardhu board.

2013-08-15net_sched: restore "linklayer atm" handlingJesper Dangaard Brouer
commit 56b765b79 ("htb: improved accuracy at high rates") broke the "linklayer atm" handling. tc class add ... htb rate X ceil Y linklayer atm The linklayer setting is implemented by modifying the rate table which is send to the kernel. No direct parameter were transferred to the kernel indicating the linklayer setting. The commit 56b765b79 ("htb: improved accuracy at high rates") removed the use of the rate table system. To keep compatible with older iproute2 utils, this patch detects the linklayer by parsing the rate table. It also supports future versions of iproute2 to send this linklayer parameter to the kernel directly. This is done by using the __reserved field in struct tc_ratespec, to convey the choosen linklayer option, but only using the lower 4 bits of this field. Linklayer detection is limited to speeds below 100Mbit/s, because at high rates the rtab is gets too inaccurate, so bad that several fields contain the same values, this resembling the ATM detect. Fields even start to contain "0" time to send, e.g. at 1000Mbit/s sending a 96 bytes packet cost "0", thus the rtab have been more broken than we first realized.
