commit f88fa79a upstream. aac_fib_map_free() calls pci_free_consistent() without checking that dev->hw_fib_va is not NULL and dev->max_fib_size is not zero.If they are indeed NULL/0, this will result in a hang as pci_free_consistent() will attempt to invalidate cache for the entire 64-bit address space (which would take a very long time). Fixed by adding a check to make sure that dev->hw_fib_va and dev->max_fib_size are not NULL and 0 respectively. Fixes: 9ad5204d - "[SCSI]aacraid: incorrect dma mapping mask during blinked recover or user initiated reset" Signed-off-by:

commit 940db6dc upstream. When an error happens during alias parsing currently the complete parsing of all attributes of the PMU is stopped. This is breaks old perf on a newer kernel that may have not-yet-know alias attributes (such as .scale or .per-pkg). Continue when some attribute is unparseable. This is IMHO a stable candidate and should be backported to older versions to avoid problems with newer kernels. v2: Print warnings when something goes wrong. v3: Change warning to debug output Signed-off-by:

commit 4392bf33 upstream. hid_ignore_special_drivers works fine until hid_scan_report autodetects and reassign devices (for hid-multitouch, hid-microsoft and hid-rmi). Simplify the handling of the parameter: if it is there, use hid-generic, no matter what, and if not, scan the device or rely on the hid_have_special_driver table. This was detected while trying to disable hid-multitouch on a Surface Pro cover which prevented to use the keyboard. Signed-off-by:

commit 264904cc upstream. Some devices I got show an inability to operate right after power on if they are already connected. They are beyond recovery if the descriptors are requested multiple times. So in case of a timeout we rather bail early and reset again. But it must be done only on the first loop lest we get into a reset/time out spiral that can be overcome with a retry. This patch is a rework of a patch that fell through the cracks. http://www.spinics.net/lists/linux-usb/msg103263.htmlSigned-off-by:

This prevents an oops in the hash_accept function of algif_hash. This commit causes the ccp-crypto module SHA support and AES CMAC support from successfully registering and causing the ccp-crypto module load to fail because the ahash import and export functions are not implemented.

commit 00df35f9 upstream. Currently, smpboot_unpark_threads() is invoked before the incoming CPU has been added to the scheduler's runqueue structures. This might potentially cause the unparked kthread to run on the wrong CPU, since the correct CPU isn't fully set up yet. That causes a sporadic, hard to debug boot crash triggering on some systems, reported by Borislav Petkov, and bisected down to: 2a442c9c ("x86: Use common outgoing-CPU-notification code") This patch places smpboot_unpark_threads() in a CPU hotplug notifier with priority set so that these kthreads are unparked just after the CPU has been added to the runqueues.

commit 8a5e5e02 upstream. Poison pointer values should be small enough to find a room in non-mmap'able/hardly-mmap'able space. E.g. on x86 "poison pointer space" is located starting from 0x0. Given unprivileged users cannot mmap anything below mmap_min_addr, it should be safe to use poison pointers lower than mmap_min_addr. The current poison pointer values of LIST_POISON{1,2} might be too big for mmap_min_addr values equal or less than 1 MB (common case, e.g. Ubuntu uses only 0x10000). There is little point to use such a big value given the "poison pointer space" below 1 MB is not yet exhausted. Changing it to a smaller value solves the problem for small mmap_min_addr setups. The values are suggested by Solar Designer: http://www.openwall.com/lists/oss-security/2015/05/02/6Signed-off-by:

commit fbd40ea0 upstream. When an inetdev is destroyed, every address assigned to the interface is removed. And in this scenerio we do two pointless things which can be very expensive if the number of assigned interfaces is large: 1) Address promotion. We are deleting all addresses, so there is no point in doing this. 2) A full nf conntrack table purge for every address. We only need to do this once, as is already caught by the existing masq_dev_notifier so masq_inet_event() can skip this. Reported-by:
