commit e35fca47 upstream. Some edac drivers register themselves as mce decoders via notifier_chain. But in current notifier_chain implementation logic, it doesn't accept same notifier registered twice. If so, it will be wrong when adding/removing the element from the list. For example, on one SandyBridge platform, remove module sb_edac and then trigger one error, it will hit oops because it has no mce decoder registered but related notifier_chain still points to an invalid callback function. Here is an example: Call Trace: [<ffffffff8150ef6a>] atomic_notifier_call_chain+0x1a/0x20 [<ffffffff8102b936>] mce_log+0x46/0x180 [<ffffffff8102eaea>] apei_mce_report_mem_error+0x4a/0x60 [<ffffffff812e19d2>] ghes_do_proc+0x192/0x210 [<ffffffff812e2066>] ghes_proc+0x46/0x70 [<ffffffff812e20d8>] ghes_notify_sci+0x48/0x80 [<ffffffff8150ef05>] notifier_call_chain+0x55/0x80 [<ffffffff81076f1a>] __blocking_notifier_call_chain+0x5a/0x80 [<ffffffff812aea11>] ? acpi_os_wait_events_complete+0x23/0x23 [<ffffffff81076f56>] blocking_notifier_call_chain+0x16/0x20 [<ffffffff812ddc4d>] acpi_hed_notify+0x19/0x1b [<ffffffff812b16bd>] acpi_device_notify+0x19/0x1b [<ffffffff812beb38>] acpi_ev_notify_dispatch+0x67/0x7f [<ffffffff812aea3a>] acpi_os_execute_deferred+0x29/0x36 [<ffffffff81069dc2>] process_one_work+0x132/0x450 [<ffffffff8106bbcb>] worker_thread+0x17b/0x3c0 [<ffffffff8106ba50>] ? manage_workers+0x120/0x120 [<ffffffff81070aee>] kthread+0x9e/0xb0 [<ffffffff81514724>] kernel_thread_helper+0x4/0x10 [<ffffffff81070a50>] ? kthread_freezable_should_stop+0x70/0x70 [<ffffffff81514720>] ? gs_change+0x13/0x13 Code: f3 49 89 d4 45 85 ed 4d 89 c6 48 8b 0f 74 48 48 85 c9 75 17 eb 41 0f 1f 80 00 00 00 00 41 83 ed 01 4c 89 f9 74 22 4d 85 ff 74 1d <4c> 8b 79 08 4c 89 e2 48 89 de 48 89 cf ff 11 4d 85 f6 74 04 41 RIP [<ffffffff8150eef6>] notifier_call_chain+0x46/0x80 RSP <ffff88042868fb20> CR2: ffffffffa01af838 ---[ end trace 0100930068e73e6f ]--- BUG: unable to handle kernel paging request at fffffffffffffff8 IP: [<ffffffff810705b0>] kthread_data+0x10/0x20 PGD 1a0d067 PUD 1a0e067 PMD 0 Oops: 0000 [#2] SMP Only i7core_edac and sb_edac have such issues because they have more than one memory controller which means they have to register mce decoder many times.

commit 9b15b817 upstream. Minchan Kim reports that when a system has many swap areas, and tmpfs swaps out to the ninth or more, shmem_getpage_gfp()'s attempts to read back the page cannot locate it, and the read fails with -ENOMEM. Whoops. Yes, I blindly followed read_swap_header()'s pte_to_swp_entry( swp_entry_to_pte()) technique for determining maximum usable swap offset, without stopping to realize that that actually depends upon the pte swap encoding shifting swap offset to the higher bits and truncating it there. Whereas our radix_tree swap encoding leaves offset in the lower bits: it's swap "type" (that is, index of swap area) that was truncated. Fix it by reducing the SWP_TYPE_SHIFT() in swapops.h, and removing the broken radix_to_swp_entry(swp_to_radix_entry()) from read_swap_header(). This does not reduce the usable size of a swap area any further, it leaves it as claimed when making the original commit: no change from 3.0 on x86_64, nor on i386 without PAE; but 3.0's 512GB is reduced to 128GB per swapfile on i386 with PAE. It's not a change I would have risked five years ago, but with x86_64 supported for ten years, I believe it's appropriate now. Hmm, and what if some architecture implements its swap pte with offset encoded below type? That would equally break the maximum usable swap offset check. Happily, they all follow the same tradition of encoding offset above type, but I'll prepare a check on that for next. Reported-and-Reviewed-and-Tested-by:

commit b3a3dd07 upstream. TEAC's UD-H01 (and probably other devices) have a gap in the interface number allocation of their descriptors: Configuration Descriptor: bLength 9 bDescriptorType 2 wTotalLength 220 bNumInterfaces 3 [...] Interface Descriptor: bLength 9 bDescriptorType 4 bInterfaceNumber 0 bAlternateSetting 0 [...] Interface Association: bLength 8 bDescriptorType 11 bFirstInterface 2 bInterfaceCount 2 bFunctionClass 1 Audio bFunctionSubClass 0 bFunctionProtocol 32 iFunction 4 Interface Descriptor: bLength 9 bDescriptorType 4 bInterfaceNumber 2 bAlternateSetting 0 [...] Once a configuration is selected, usb_set_configuration() walks the known interfaces of a given configuration and calls find_iad() on each of them to set the interface association pointer the interface is included in. The problem here is that the loop variable is taken for the interface number in the comparison logic that gathers the association. Which is fine as long as the descriptors are sane. In the case above, however, the logic gets out of sync and the interface association fields of all interfaces beyond the interface number gap are wrong. Fix this by passing the interface's bInterfaceNumber to find_iad() instead. Signed-off-by:

commit 6c4707f3 upstream. Currently CDC-ACM devices stay throttled when their TTY is closed while throttled, stalling further communication attempts after the next open. Unthrottling during open/activate got lost starting with kernel 3.0.0 and this patch reintroduces it. Signed-off-by:

commit aaa0ef28 upstream. PS3 EHCI HC errata fix 244. The SCC EHCI HC will not correctly perform QH reads that occur near or span a micro-frame boundry. This is due to a problem in the Nak Count Reload Control logic (EHCI Specification 1.0 Section 4.9.1). The work-around for this problem is for the HC driver to set I=1 (inactive) for QHs with H=1 (list head). Signed-off-by:

commit 622eb783 upstream. When system software decides to power down the xHC with the intent of resuming operation at a later time, it will ask xHC to save the internal state and restore it when resume to correctly recover from a power event. Two bits are used to enable this operation: Save State and Restore State. xHCI spec 4.23.2 says software should "Set the Controller Save/Restore State flag in the USBCMD register and wait for the Save/Restore State Status flag in the USBSTS register to transition to '0'". However, it does not define how long software should wait for the SSS/RSS bit to transition to 0. Currently the timeout is set to 1ms. There is bug report (https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1002697) indicates that the timeout is too short for ASMedia ASM1042 host controller to save/restore the state successfully. Increase the timeout to 10ms helps to resolve the issue. This patch should be backported to stable kernels as old as 2.6.37, that contain the commit 5535b1d5 "USB: xHCI: PCI power management implementation" Signed-off-by:

commit 32f1d2c5 upstream. This patch fixes a few issues introduced in the recent fix [f8a9e72d: USB: fix resource leak in xhci power loss path] - The endpoints listed in bw table are just links and each entry is an array member of dev->eps[]. But the commit above adds a kfree() call to these instances, and thus it results in memory corruption. - It clears only the first entry of rh_bw[], but there can be multiple ports. - It'd be safer to clear the list_head of ep as well, not only removing from the list, as it's checked in xhci_discover_or_reset_device(). This patch should be backported to kernels as old as 3.2, that contain the commit 839c817c "xhci: Store information about roothubs and TTs." Signed-off-by:

commit 46ed8f00 upstream. xhci_free_tt_info() may access the invalid memory when it removes the last entry but the list is not empty. Then tt_next reaches to the list head but it still tries to check the tt_info of that entry. This patch fixes the bug and cleans up the messy code by rewriting with a simple list_for_each_entry_safe(). This patch should be backported to kernels as old as 3.2, that contain the commit 839c817c "xhci: Store information about roothubs and TTs." Signed-off-by:

commit 954c3f8a upstream. We need to make sure that the USB serial driver we find matches the USB driver whose probe we are currently executing. Otherwise we will end up with USB serial devices bound to the correct serial driver but wrong USB driver.

The reason for the above is simple: The USB driver probe will succeed if *any* registered serial driver matches, and will use that serial driver for all serial driver functions.

commit c2fb8a3f upstream. This patch (as1558) fixes a problem affecting several ASUS computers: The machine crashes or corrupts memory when going into suspend if the ehci-hcd driver is bound to any controllers. Users have been forced to unbind or unload ehci-hcd before putting their systems to sleep. After extensive testing, it was determined that the machines don't like going into suspend when any EHCI controllers are in the PCI D3 power state. Presumably this is a firmware bug, but there's nothing we can do about it except to avoid putting the controllers in D3 during system sleep. The patch adds a new flag to indicate whether the problem is present, and avoids changing the controller's power state if the flag is set. Runtime suspend is unaffected; this matters only for system suspend. However as a side effect, the controller will not respond to remote wakeup requests while the system is asleep. Hence USB wakeup is not functional -- but of course, this is already true in the current state of affairs. A similar patch has already been applied as commit 151b6128 (USB: EHCI: fix crash during suspend on ASUS computers). The patch supersedes that one and reverts it. There are two differences: The old patch added the flag at the USB level; this patch adds it at the PCI level. The old patch applied to all chipsets with the same vendor, subsystem vendor, and product IDs; this patch makes an exception for a known-good system (based on DMI information). Signed-off-by:

commit 59e4f541 upstream. The error paths in target_emulate_set_target_port_groups() are all essentially "rc = -EINVAL; goto out;" but the code at "out:" ignores rc and always returns success. This means that even if eg explicit ALUA is turned off, the initiator will always see a good SCSI status for SET TARGET PORT GROUPS. Fix this by returning rc as is intended.

commit fec67b45 upstream. [v2: Editorial changes suggested by Sergei Shtylyov] These modems use the Qualcomm MSM Interface (QMI) protocol for management of their CDC ECM like wwan interface. This driver is perfect for exporting the protocol to userspace. The created character device will be indistinguishable from a common AT command based Device Management interface, so userspace applications must do some intelligent matching on the USB device.

This patch ensures that nfs4_do_open strips the other fmode_t bits, fixing a problem in which the nfs4_do_open call would result in an unnecessary delegation return. Reported-by:

commit 602bf409 upstream. There is a system hang issue on imx6q which can easily be seen with running a cpu hotplug stress testing (hotplug secondary cores from user space via sysfs interface for thousands iterations). It turns out that the issue is caused by coherency of the cpu that is being shut down. When shutting down a cpu, we need to have the cpu exit coherency to prevent it from receiving cache, TLB, or BTB maintenance operations broadcast by other CPUs in the cluster. Copy cpu_enter_lowpower() and cpu_leave_lowpower() from mach-vexpress to have coherency properly handled in platform_cpu_die(), thus fix the issue. Signed-off-by:
