2015-06-16net/Kconfig: paranoid only for androidv3.18/topic/aosp-fixesKevin Hilman
Currently, paranoid networking is enabled by default whether or not and android kernel is being built. However, it should be enabled by default only when and Android kernel is being built. To fix, use "default ANDROID" instead of "default y" Change-Id: Ia19ab766e3497f07ccee846bec1f5fd4017e5977 Cc: John Stultz <john.stultz@linaro.org> Signed-off-by: Kevin Hilman <khilman@linaro.org>

2015-06-14md/raid0: fix restore to sector variable in raid0_make_requestEric Work
[ Upstream commit a81157768a00e8cf8a7b43b5ea5cac931262374f ] The variable "sector" in "raid0_make_request()" was improperly updated by a call to "sector_div()" which modifies its first argument in place. Commit 47d68979cc968535cb87f3e5f2e6a3533ea48fbd restored this variable after the call for later re-use. Unfortunetly the restore was done after the referenced variable "bio" was advanced. This lead to the original value and the restored value being different. Here we move this line to the proper place. One observed side effect of this bug was discarding a file though unlinking would cause an unrelated file's contents to be discarded.

[ Upstream commit 161f873b89136eb1e69477c847d5a5033239d9ba ] We used to read file_handle twice. Once to get the amount of extra bytes, and once to fetch the entire structure. This may be problematic since we do size verifications only after the first read, so if the number of extra bytes changes in userspace between the first and second calls, we'll have an incoherent view of file_handle. Instead, read the constant size once, and copy that over to the final structure without having to re-read it again.

[ Upstream commit b9a5e5e18fbf223502c0b2264c15024e393da928 ] Since acpi_reserve_resources() is defined as a device_initcall(), there's no guarantee that it will be executed in the right order with respect to the rest of the ACPI initialization code. On some systems this leads to breakage if, for example, the address range that should be reserved for the ACPI fixed registers is given to the PCI host bridge instead if the race is won by the wrong code path. Fix this by turning acpi_reserve_resources() into a void function and calling it directly from within the ACPI initialization sequence.

2015-06-10firmware: dmi_scan: Fix ordering of product_uuidJean Delvare
[ Upstream commit 5c1ac56b51b9d222ab202dec1ac2f4215346129d ] In function dmi_present(), dmi_walk_early() calls dmi_table(), which calls dmi_decode(), which ultimately calls dmi_save_uuid(). This last function makes a decision based on the value of global variable dmi_ver. The problem is that this variable is set right _after_ dmi_walk_early() returns. So dmi_save_uuid() always sees dmi_ver == 0 regardless of the actual version implemented. This causes /sys/class/dmi/id/product_uuid to always use the old ordering even on systems implementing DMI/SMBIOS 2.6 or later, which should use the new ordering. This is broken since kernel v3.8 for legacy DMI implementations and since kernel v3.10 for SMBIOS 2 implementations. SMBIOS 3 implementations with the 64-bit entry point are not affected. The first breakage does not matter much as in practice legacy DMI implementations are always for versions older than 2.6, which is when the UUID ordering changed. The second breakage is more problematic as it affects the vast majority of x86 systems manufactured since 2009.

2015-06-10mm, numa: really disable NUMA balancing by default on single node machinesMel Gorman
[ Upstream commit b0dc2b9bb4ab782115b964310518ee0b17784277 ] NUMA balancing is meant to be disabled by default on UMA machines but the check is using nr_node_ids (highest node) instead of num_online_nodes (online nodes). The consequences are that a UMA machine with a node ID of 1 or higher will enable NUMA balancing. This will incur useless overhead due to minor faults with the impact depending on the workload. These are the impact on the stats when running a kernel build on a single node machine whose node ID happened to be 1: vanilla patched NUMA base PTE updates 5113158 0 NUMA huge PMD updates 643 0 NUMA page range updates 5442374 0 NUMA hint faults 2109622 0 NUMA hint local faults 2109622 0 NUMA hint local percent 100 100 NUMA pages migrated 0 0 Signed-off-by: Mel Gorman <mgorman@suse.de> Reviewed-by: Rik van Riel <riel@redhat.com> Cc: <stable@vger.kernel.org> [3.8+] Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> Signed-off-by: Sasha Levin <sasha.levin@oracle.com>

2015-06-10parisc,metag: Fix crashes due to stack randomization on stack-grows-upwards ↵Helge Deller
architectures [ Upstream commit d045c77c1a69703143a36169c224429c48b9eecd ] On architectures where the stack grows upwards (CONFIG_STACK_GROWSUP=y, currently parisc and metag only) stack randomization sometimes leads to crashes when the stack ulimit is set to lower values than STACK_RND_MASK (which is 8 MB by default if not defined in arch-specific headers). The problem is, that when the stack vm_area_struct is set up in fs/exec.c, the additional space needed for the stack randomization (as defined by the value of STACK_RND_MASK) was not taken into account yet and as such, when the stack randomization code added a random offset to the stack start, the stack effectively got smaller than what the user defined via rlimit_max(RLIMIT_STACK) which then sometimes leads to out-of-stack situations and crashes. This patch fixes it by adding the maximum possible amount of memory (based on STACK_RND_MASK) which theoretically could be added by the stack randomization code to the initial stack size. That way, the user-defined stack size is always guaranteed to be at minimum what is defined via rlimit_max(RLIMIT_STACK). This bug is currently not visible on the metag architecture, because on metag STACK_RND_MASK is defined to 0 which effectively disables stack randomization. The changes to fs/exec.c are inside an "#ifdef CONFIG_STACK_GROWSUP" section, so it does not affect other platformws beside those where the stack grows upwards (parisc and metag).

[ Upstream commit 1b97937246d8b97c0760d16d8992c7937bdf5e6a ] Josh Stone reports: I've discovered a case where both arm and arm64 will miss a ptrace syscall-exit that they should report. If the syscall is entered without TIF_SYSCALL_TRACE set, then it goes on the fast path. It's then possible to have TIF_SYSCALL_TRACE added in the middle of the syscall, but ret_fast_syscall doesn't check this flag again. Fix this by always checking for a syscall trace in the fast exit path.

2015-06-10ARM: 8356/1: mm: handle non-pmd-aligned end of RAMMark Rutland
[ Upstream commit 965278dcb8ab0b1f666cc47937933c4be4aea48d ] At boot time we round the memblock limit down to section size in an attempt to ensure that we will have mapped this RAM with section mappings prior to allocating from it. When mapping RAM we iterate over PMD-sized chunks, creating these section mappings. Section mappings are only created when the end of a chunk is aligned to section size. Unfortunately, with classic page tables (where PMD_SIZE is 2 * SECTION_SIZE) this means that if a chunk is between 1M and 2M in size the first 1M will not be mapped despite having been accounted for in the memblock limit. This has been observed to result in page tables being allocated from unmapped memory, causing boot-time hangs. This patch modifies the memblock limit rounding to always round down to PMD_SIZE instead of SECTION_SIZE. For classic MMU this means that we will round the memblock limit down to a 2M boundary, matching the limits on section mappings, and preventing allocations from unmapped memory. For LPAE there should be no change as PMD_SIZE == SECTION_SIZE.

[ Upstream commit 0782e63bc6fe7e2d3408d250df11d388b7799c6b ] Ronny reported that the following scenario is not handled correctly: T1 (prio = 10) lock(rtmutex); T2 (prio = 20) lock(rtmutex) boost T1 T1 (prio = 20) sys_set_scheduler(prio = 30) T1 prio = 30 .... sys_set_scheduler(prio = 10) T1 prio = 30 The last step is wrong as T1 should now be back at prio 20. Commit c365c292d059 ("sched: Consider pi boosting in setscheduler()") only handles the case where a boosted tasks tries to lower its priority.
