commit 6cdb0817 upstream. Fixes a race condition in abort handling that was injected when multiple interrupt support was added. When only a single interrupt is present, the adapter guarantees it will send responses for aborted commands prior to the response for the abort command itself. With multiple interrupts, these responses generally come back on different interrupts, so we need to ensure the abort thread waits until the aborted command is complete so we don't perform a double completion. This race condition was being hit frequently in environments which were triggering command timeouts, which was resulting in a double completion causing a kernel oops. Signed-off-by:

commit 378ff1a5 upstream. It really needs to check that src is non-directory *and* use {un,}lock_two_nodirectories(). As it is, it's trivial to cause double-lock (ioctl(fd, CIFS_IOC_COPYCHUNK_FILE, fd)) and if the last argument is an fd of directory, we are asking for trouble by violating the locking order - all directories go before all non-directories. If the last argument is an fd of parent directory, it has 50% odds of locking child before parent, which will cause AB-BA deadlock if we race with unlink(). Signed-off-by:

commit 8f1e8ee2 upstream. The current hardware I/O coherency is known to cause problems with DMA coherent buffers, as it still requires explicit I/O synchronization barriers, which is not compatible with the semantics expected by the Linux DMA coherent buffers API. So, in order to have enough time to validate a new solution based on automatic I/O synchronization barriers, this commit disables hardware I/O coherency entirely. Future patches will re-enable it.

commit 29187a9e upstream. A worker_pool's forward progress is guaranteed by the fact that the last idle worker assumes the manager role to create more workers and summon the rescuers if creating workers doesn't succeed in timely manner before proceeding to execute work items. This manager role is implemented in manage_workers(), which indicates whether the worker may proceed to work item execution with its return value. This is necessary because multiple workers may contend for the manager role, and, if there already is a manager, others should proceed to work item execution. Unfortunately, the function also indicates that the worker may proceed to work item execution if need_to_create_worker() is false at the head of the function. need_to_create_worker() tests the following conditions. pending work items && !nr_running && !nr_idle The first and third conditions are protected by pool->lock and thus won't change while holding pool->lock; however, nr_running can change asynchronously as other workers block and resume and while it's likely to be zero, as someone woke this worker up in the first place, some other workers could have become runnable inbetween making it non-zero. If this happens, manage_worker() could return false even with zero nr_idle making the worker, the last idle one, proceed to execute work items. If then all workers of the pool end up blocking on a resource which can only be released by a work item which is pending on that pool, the whole pool can deadlock as there's no one to create more workers or summon the rescuers. This patch fixes the problem by removing the early exit condition from maybe_create_worker() and making manage_workers() return false iff there's already another manager, which ensures that the last worker doesn't start executing work items. We can leave the early exit condition alone and just ignore the return value but the only reason it was put there is because the manage_workers() used to perform both creations and destructions of workers and thus the function may be invoked while the pool is trying to reduce the number of workers. Now that manage_workers() is called only when more workers are needed, the only case this early exit condition is triggered is rare race conditions rendering it pointless. Tested with simulated workload and modified workqueue code which trigger the pool deadlock reliably without this patch. Signed-off-by:

commit 851b0936 upstream. Every PCI-PCI bridge window should fit inside an upstream bridge window because orphaned address space is unreachable from the primary side of the upstream bridge.

commit 8505e729 upstream. Add pci_claim_bridge_resource() to claim a PCI-PCI bridge window. This is like regular pci_claim_resource(), except that if we fail to claim the window, we check to see if we can reduce the size of the window and try again. This is for scenarios like this: pci_bus 0000:00: root bus resource [mem 0xc0000000-0xffffffff] pci 0000:00:01.0: bridge window [mem 0xbdf00000-0xddefffff 64bit pref] pci 0000:01:00.0: reg 0x10: [mem 0xc0000000-0xcfffffff pref] The 00:01.0 window is illegal: it starts before the host bridge window, so we have to assume the [0xbdf00000-0xbfffffff] region is inaccessible. We can make it legal by clipping it to [mem 0xc0000000-0xddefffff 64bit pref]. Previously we discarded the 00:01.0 window and tried to reassign that part of the hierarchy from scratch. That is a problem because Linux doesn't always assign things optimally. For example, in this case, BIOS put the 01:00.0 device in a prefetchable window below 4GB, but after 5b285415, Linux puts the prefetchable window above 4GB where the 32-bit 01:00.0 device can't use it. Clipping the 00:01.0 window is less intrusive than completely reassigning things and is sufficient to let us use most of the BIOS configuration. Of course, it's possible that devices below 00:01.0 will no longer fit. If that's the case, we'll have to reassign things. But that's a separate problem.

commit c3e59ee4 upstream. Reports against the TL-WDN4800 card indicate that PCI bus reset of this Atheros device cause system lock-ups and resets. I've also been able to confirm this behavior on multiple systems. The device never returns from reset and attempts to access config space of the device after reset result in hangs. Blacklist bus reset for the device to avoid this issue. [bhelgaas: This regression appeared in v3.14. Andreas bisected it to 425c1b22 ("PCI: Add Virtual Channel to save/restore support"), but we don't understand the mechanism by which that commit affects the reset path.] [bhelgaas: changelog, references] Link: http://lkml.kernel.org/r/20140923210318.498dacbd@dualc.maya.orgReported-by:

commit f331a859 upstream. Enable a mechanism for devices to quirk that they do not behave when doing a PCI bus reset. We require a modest level of spec compliant behavior in order to do a reset, for instance the device should come out of reset without throwing errors and PCI config space should be accessible after reset. This is too much to ask for some devices. Link: http://lkml.kernel.org/r/20140923210318.498dacbd@dualc.maya.orgSigned-off-by:

commit 889b77f7 upstream. Flooding the Kvaser CAN to USB dongle with multiple reads and writes in very high frequency (*), closing the CAN channel while all the transmissions are on (#), opening the device again (@), then sending a small number of packets would make the driver enter an almost infinite loop of: [....] [15959.853988] kvaser_usb 4-3:1.0 can0: cannot find free context [15959.853990] kvaser_usb 4-3:1.0 can0: cannot find free context [15959.853991] kvaser_usb 4-3:1.0 can0: cannot find free context [15959.853993] kvaser_usb 4-3:1.0 can0: cannot find free context [15959.853994] kvaser_usb 4-3:1.0 can0: cannot find free context [15959.853995] kvaser_usb 4-3:1.0 can0: cannot find free context [....] _dragging the whole system down_ in the process due to the excessive logging output. Initially, this has caused random panics in the kernel due to a buggy error recovery path. That got fixed in an earlier commit.(%) This patch aims at solving the root cause. --> 16 tx URBs and contexts are allocated per CAN channel per USB device. Such URBs are protected by: a) A simple atomic counter, up to a value of MAX_TX_URBS (16) b) A flag in each URB context, stating if it's free c) The fact that ndo_start_xmit calls are themselves protected by the networking layers higher above After grabbing one of the tx URBs, if the driver noticed that all of them are now taken, it stops the netif transmission queue. Such queue is worken up again only if an acknowedgment was received from the firmware on one of our earlier-sent frames. Meanwhile, upon channel close (#), the driver sends a CMD_STOP_CHIP to the firmware, effectively closing all further communication. In the high traffic case, the atomic counter remains at MAX_TX_URBS, and all the URB contexts remain marked as active. While opening the channel again (@), it cannot send any further frames since no more free tx URB contexts are available. Reset all tx URB contexts upon CAN channel close.

commit b442723f upstream. Flooding the Kvaser CAN to USB dongle with multiple reads and writes in high frequency caused seemingly-random panics in the kernel. On further inspection, it seems the driver erroneously freed the to-be-transmitted packet upon getting tight on URBs and returning NETDEV_TX_BUSY, leading to invalid memory writes and double frees at a later point in time. Note: Finding no more URBs/transmit-contexts and returning NETDEV_TX_BUSY is a driver bug in and out of itself: it means that our start/stop queue flow control is broken. This patch only fixes the (buggy) error handling code; the root cause shall be fixed in a later commit. Acked-by:

commit 9b1087aa upstream. When changing flags in the CAN drivers ctrlmode the provided new content has to be checked whether the bits are allowed to be changed. The bits that are to be changed are given as a bitfield in cm->mask. Therefore checking against cm->flags is wrong as the content can hold any kind of values. The iproute2 tool sets the bits in cm->mask and cm->flags depending on the detected command line options. To be robust against bogus user space applications additionally sanitize the provided flags with the provided mask. Cc: Wolfgang Grandegger <wg@grandegger.com> Signed-off-by:

commit 00acc3dc upstream. Fix memory leak and sleep-while-atomic in gpiochip_remove. The memory leak was introduced by afa82fab ("gpio / ACPI: Move event handling registration to gpiolib irqchip helpers") that moved the release of acpi interrupt resources to gpiochip_irqchip_remove, but by then the resources are no longer accessible as the acpi_gpio_chip has already been freed by acpi_gpiochip_remove. Note that this also fixes a few potential sleep-while-atomics, which has been around since 14250520 ("gpio: add IRQ chip helpers in gpiolib") when the call to gpiochip_irqchip_remove while holding a spinlock was added (a couple of irq-domain paths can end up grabbing mutexes).
