commit 178db7d3 upstream. Device are added as children of the bus master's parent device, but spi_unregister_master() looks for devices to unregister in the bus master's children. This results in the child devices not being unregistered. Fix this by registering devices as direct children of the bus master. Signed-off-by:

commit 93dc6107 upstream. Commit 28d82dc1 ("epoll: limit paths") that I did to limit the number of possible wakeup paths in epoll is causing a few applications to longer work (dovecot for one). The original patch is really about limiting the amount of epoll nesting (since epoll fds can be attached to other fds). Thus, we probably can allow an unlimited number of paths of depth 1. My current patch limits it at 1000. And enforce the limits on paths that have a greater depth. This is captured in: https://bugzilla.redhat.com/show_bug.cgi?id=681578Signed-off-by:

commit f67fd55f upstream. Some BIOS implementations leave the Intel GPU interrupts enabled, even though no one is handling them (f.e. i915 driver is never loaded). Additionally the interrupt destination is not set up properly and the interrupt ends up -somewhere-. These spurious interrupts are "sticky" and the kernel disables the (shared) interrupt line after 100.000+ generated interrupts. Fix it by disabling the still enabled interrupts. This resolves crashes often seen on monitor unplug. Tested on the following boards: - Intel DH61CR: Affected - Intel DH67BL: Affected - Intel S1200KP server board: Affected - Asus P8H61-M LE: Affected, but system does not crash. Probably the IRQ ends up somewhere unnoticed. According to reports on the net, the Intel DH61WW board is also affected. Many thanks to Jesse Barnes from Intel for helping with the register configuration and to Intel in general for providing public hardware documentation. Signed-off-by:

commit ad579699 upstream. pm_runtime_get_sync returns a signed integer. In case of errors it returns a negative value. This patch fixes the error check by making it signed instead of unsigned thus preventing register access if get_sync_fails. Also passes the error cause to the debug message.

commit 8963c487 upstream. This patch (as154) fixes a self-deadlock that occurs when userspace writes to the bConfigurationValue sysfs attribute for a hub with children. The task tries to lock the bandwidth_mutex at a time when it already owns the lock: The attribute's method calls usb_set_configuration(), which calls usb_disable_device() with the bandwidth_mutex held. usb_disable_device() unregisters the existing interfaces, which causes the hub driver to be unbound. The hub_disconnect() routine calls hub_quiesce(), which calls usb_disconnect() for each of the hub's children. usb_disconnect() attempts to acquire the bandwidth_mutex around a call to usb_disable_device(). The solution is to make usb_disable_device() acquire the mutex for itself instead of requiring the caller to hold it. Then the mutex can cover only the bandwidth deallocation operation and not the region where the interfaces are unregistered. This has the potential to change system behavior slightly when a config change races with another config or altsetting change. Some of the bandwidth released from the old config might get claimed by the other config or altsetting, make it impossible to restore the old config in case of a failure. But since we don't try to recover from config-change failures anyway, this doesn't matter. [This should be marked for stable kernels that contain the commit fccf4e86 "USB: Free bandwidth when usb_disable_device is called." That commit was marked for stable kernels as old as 2.6.32.] Signed-off-by:

commit 2fbe2bf1 upstream. This patch (as1544) fixes a problem affecting some EHCI controllers. They can generate interrupts whenever the STS_FLR status bit is turned on, even though that bit is masked out in the Interrupt Enable register. Since the driver doesn't use STS_FLR anyway, the patch changes the interrupt routine to clear that bit whenever it is set, rather than leaving it alone. Signed-off-by:

commit 749541d1 upstream. These devices have a number of non serial interfaces as well. Use the existing "Direct IP" blacklist to prevent binding to interfaces which are handled by other drivers. We also extend the "Direct IP" blacklist with with interfaces only seen in "QMI" mode, assuming that these devices use the same interface numbers for serial interfaces both in "Direct IP" and in "QMI" mode.

commit af6d17cd upstream. This driver anticipates pch_uart_verify_port() is not called during installation. However, actually pch_uart_verify_port() is called during installation. As a result, memory access violation occurs like below. 0. initial value: use_dma=0 1. starup() - dma channel is not allocated because use_dma=0 2. pch_uart_verify_port() - Set use_dma=1 3. UART processing acts DMA mode because use_dma=1 - memory access violation occurs! This patch fixes the issue. Solution: Whenever pch_uart_verify_port() is called and then dma channel is not allocated, the channel should be allocated. Signed-off-by:

commit aca50bd3 upstream. Mel reports a BUG_ON(slot == NULL) in radix_tree_tag_set() on s390 3.0.13: called from __set_page_dirty_nobuffers() when page_remove_rmap() tries to transfer dirty flag from s390 storage key to struct page and radix_tree. That would be because of reclaim's shrink_page_list() calling add_to_swap() on this page at the same time: first PageSwapCache is set (causing page_mapping(page) to appear as &swapper_space), then page->private set, then tree_lock taken, then page inserted into radix_tree - so there's an interval before taking the lock when the radix_tree slot is empty. We could fix this by moving __add_to_swap_cache()'s spin_lock_irq up before the SetPageSwapCache. But a better fix is simply to do what's five years overdue: Ken Chen introduced __set_page_dirty_no_writeback() (if !PageDirty TestSetPageDirty) for tmpfs to skip all the radix_tree overhead, and swap is just the same - it ignores the radix_tree tag, and does not participate in dirty page accounting, so should be using __set_page_dirty_no_writeback() too. s390 testing now confirms that this does indeed fix the problem.

commit 5b76d060 upstream. Under heavy load (flood ping) it is possible for the MDIO timeout to expire before the loop checks the GO bit again. This patch adds an additional check whether the operation was done before actually returning -ETIMEDOUT. To reproduce this bug, flood ping the device, e.g., ping -f -l 1000 After some time, a "timed out waiting for user access" warning may appear. And even worse, link may go down since the PHY reported a timeout. Signed-off-by:

commit 3066616c upstream. A rather annoying and common case is when booting a PVonHVM guest and exposing the PV KBD and PV VFB - as broken toolstacks don't always initialize the backends correctly. Normally The HVM guest is using the VGA driver and the emulated keyboard for this (though upstream version of QEMU implements PV KBD, but still uses a VGA driver). We provide a very basic two-stage wait mechanism - where we wait for 30 seconds for all devices, and then for 270 for all them except the two mentioned. That allows us to wait for the essential devices, like network or disk for the full 6 minutes. To trigger this, put this in your guest config: vfb = [ 'vnc=1, vnclisten=0.0.0.0 ,vncunused=1'] instead of this: vnc=1 vnclisten="0.0.0.0" Acked-by:

commit cd94154c upstream. Git commit 36409f63 "use generic RCU page-table freeing code" introduced a tlb flushing bug. Partially revert the above git commit and go back to s390 specific page table flush code. For s390 the TLB can contain three types of entries, "normal" TLB page-table entries, TLB combined region-and-segment-table (CRST) entries and real-space entries. Linux does not use real-space entries which leaves normal TLB entries and CRST entries. The CRST entries are intermediate steps in the page-table translation called translation paths. For example a 4K page access in a three-level page table setup will create two CRST TLB entries and one page-table TLB entry. The advantage of that approach is that a page access next to the previous one can reuse the CRST entries and needs just a single read from memory to create the page-table TLB entry. The disadvantage is that the TLB flushing rules are more complicated, before any page-table may be freed the TLB needs to be flushed. In short: the generic RCU page-table freeing code is incorrect for the CRST entries, in particular the check for mm_users < 2 is troublesome. This is applicable to 3.0+ kernels. Signed-off-by:

commit bdbb776f upstream. It was possible to extract the robust list head address from a setuid process if it had used set_robust_list(), allowing an ASLR info leak. This changes the permission checks to be the same as those used for similar info that comes out of /proc. Running a setuid program that uses robust futexes would have had: cred->euid != pcred->euid cred->euid == pcred->uid so the old permissions check would allow it. I'm not aware of any setuid programs that use robust futexes, so this is just a preventative measure. (This patch is based on changes from grsecurity.) Signed-off-by:

commit afbaa90b upstream. If a bitmap is added while the array is active, it is possible for bitmap_daemon_work to run while the bitmap is being initialised. This is particularly a problem if bitmap_daemon_work sees bitmap->filemap as non-NULL before it has been filled in properly. So hold bitmap_info.mutex while filling in ->filemap to prevent problems. This patch is suitable for any -stable kernel, though it might not apply cleanly before about 3.1. Signed-off-by:
