This intermediate patch revamps the vclock_gettime.c by moving some functions around. It is only for spliting purpose, to make whole the 32 bit vdso timer patch easier to review.

The _install_special_mapping() is the new base function for install_special_mapping(). This function will return a pointer of the created VMA or a error code in an ERR_PTR() This new function will be needed by the for the vdso 32 bit support to map the additonal vvar and hpet pages into the 32 bit address space. This will be done with io_remap_pfn_range() and remap_pfn_range, which requieres a vm_area_struct.

This patch move the vsyscall_gtod_data handling out of vsyscall_64.c into an additonal file vsyscall_gtod.c to make the functionality available for x86 32 bit kernel. It also adds a new vsyscall_32.c which setup the VVAR page.

The only reason that the user bit was set was to support userspace access to the compat vDSO in the fixmap. The compat vDSO is gone, so the user bit can be removed.

The compat vDSO is a complicated hack that's needed to maintain compatibility with a small range of glibc versions. This removes it and replaces it with a much simpler hack: a config option to disable the 32-bit vDSO by default. This also changes the default value of CONFIG_COMPAT_VDSO to n -- users configuring kernels from scratch almost certainly want that choice.

This fixes CVE-2014-0102. The following command sequence produces an oops: keyctl new_session i=`keyctl newring _ses @s` keyctl link @s $i The problem is that search_nested_keyrings() sees two keyrings that have matching type and description, so keyring_compare_object() returns true. s_n_k() then passes the key to the iterator function - keyring_detect_cycle_iterator() - which *should* check to see whether this is the keyring of interest, not just one with the same name. Because assoc_array_find() will return one and only one match, I assumed that the iterator function would only see an exact match or never be called - but the iterator isn't only called from assoc_array_find()... The oops looks something like this: kernel BUG at /data/fs/linux-2.6-fscache/security/keys/keyring.c:1003! invalid opcode: 0000 [#1] SMP ... RIP: keyring_detect_cycle_iterator+0xe/0x1f ...

A testcase has been included in the keyutils testsuite for this: http://git.kernel.org/cgit/linux/kernel/git/dhowells/keyutils.git/commit/?id=891f3365d07f1996778ade0e3428f01878a1790bReported-by: Tommi Rantala <tt.rantala@gmail.com> Signed-off-by: David Howells <dhowells@redhat.com> Acked-by: James Morris <james.l.morris@oracle.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

Pull ACPI and power management fixes from Rafael Wysocki: - ACPI tables in some BIOSes list device resources with size equal to 0, which doesn't make sense, so we should ignore them, but instead we try to use them and mangle things completely. Fix from Zhang Rui. - Several models of Samsung laptops accumulate EC events when they are in sleep states which leads to EC buffer overflows that prevent new events from being signaled after system resume or reboot. This has been affecting many users for quite a while and may be addressed by clearing the EC buffer during system resume and system startup on those machines. From Kieran Clancy. - If the ACPI sleep control and status registers are not present (which happens if the Hardware Reduced ACPI mode bit is set in the ACPI tables, but also may result from BIOS bugs), we should not try to use ACPI to power off the system and ACPI S5 should not be listed as supported. Fix from Aubrey Li. - There's a race condition in cpufreq_get() that leads to a kernel crash if that function is called at a wrong time. Fix from Aaron Plattner. - cpufreq policy objects have to be initialized entirely before they are first accessed by their users which isn't the case currently and that potentially leads to various kinds of breakage that is difficult to debug.

It's an enum, not a #define, you can't use it in asm files. Introduced in commit 5fa10196 ("x86: Ignore NMIs that come in during early boot"), and sadly I didn't compile-test things like I should have before pushing out. My weak excuse is that the x86 tree generally doesn't introduce stupid things like this (and the ARM pull afterwards doesn't cause me to do a compile-test either, since I don't cross-compile).

Merge tag 'trace-fixes-v3.14-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace Pull tracing fix from Steven Rostedt: "In the past, I've had lots of reports about trace events not working. Developers would say they put a trace_printk() before and after the trace event but when they enable it (and the trace event said it was enabled) they would see the trace_printks but not the trace event. I was not able to reproduce this, but that's because I wasn't looking at the right location. Recently, another bug came up that showed the issue. If your kernel supports signed modules but allows for non-signed modules to be loaded, then when one is, the kernel will silently set the MODULE_FORCED taint on the module. Although, this taint happens without the need for insmod --force or anything of the kind, it labels the module with that taint anyway. If this tainted module has tracepoints, the tracepoints will be ignored because of the MODULE_FORCED taint. But no error message will be displayed. Worse yet, the event infrastructure will still be created letting users enable the trace event represented by the tracepoint, although that event will never actually be enabled. This is because the tracepoint infrastructure allows for non-existing tracepoints to be enabled for new modules to arrive and have their tracepoints set. Although there are several things wrong with the above, this change only addresses the creation of the trace event files for tracepoints that are not created when a module is loaded and is tainted. This change will print an error message about the module being tainted and not the trace events will not be created, and it does not create the trace event infrastructure" * tag 'trace-fixes-v3.14-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: tracing: Do not add event files for modules that fail tracepoints

Pull device mapper fixes from Mike Snitzer: - dm-cache memory allocation failure fix - fix DM's Kconfig identation - dm-snapshot metadata corruption fix for bug introduced in 3.14-rc1 - important refcount < 0 fix for the DM persistent data library's space map metadata interface which fixes corruption reported by a few dm-thinp users and last but not least: - more extensive fixes than ideal for dm-thinp's data resize capability (which has had growing pain much like we've seen from -ENOSPC handling of filesystems that mature). The end result is dm-thinp now handles metadata operation failure and no data space error conditions much better than before. * tag 'dm-3.14-fixes-3' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm: dm space map metadata: fix refcount decrement below 0 which caused corruption dm thin: fix Documentation for held metadata root feature dm thin: fix noflush suspend IO queueing dm thin: fix deadlock in __requeue_bio_list dm thin: fix out of data space handling dm thin: ensure user takes action to validate data and metadata consistency dm thin: synchronize the pool mode during suspend dm snapshot: fix metadata corruption dm: fix Kconfig indentation dm cache mq: fix memory allocation failure for large cache devices

Don Zickus reports: A customer generated an external NMI using their iLO to test kdump worked. Unfortunately, the machine hung. Disabling the nmi_watchdog made things work. I speculated the external NMI fired, caused the machine to panic (as expected) and the perf NMI from the watchdog came in and was latched. My guess was this somehow caused the hang. ---- It appears that the latched NMI stays latched until the early page table generation on 64 bits, which causes exceptions to happen which end in IRET, which re-enable NMI. Therefore, ignore NMIs that come in during early execution, until we have proper exception handling.

Commit 017f161a (ARM: 7877/1: use built-in byte swap function) added bswapsdi2.{o,S} to arch/arm/boot/compressed/Makefile, but didn't update the .gitignore. Thus after a a build git status shows bswapsdi2.S as a new file, which is a little annoying. This patch updates arch/arm/boot/compressed/.gitignore to ignore bswapsdi2.S, as we already do for ashldi3.S and others.

Due to a problem in the MFD Kconfig it was not possible to compile the UCB battery driver for the Collie SA1100 system, in turn making it impossible to compile in the battery driver. (See patch "mfd: include all drivers in subsystem menu".) After fixing the MFD Kconfig (separate patch) a compile error appears in the Collie battery driver due to the <mach/collie.h> implicitly requiring <mach/hardware.h> through <linux/gpio.h> via <mach/gpio.h> prior to commit 40ca061b "ARM: 7841/1: sa1100: remove complex GPIO interface". Fix this up by including the required header into <mach/collie.h>.

With noMMU, CONFIG_PAGE_OFFSET was not being set correctly. As there's no MMU, PAGE_OFFSET should be equal to PHYS_OFFSET in all cases. This commit makes that explicit. Since we do this, we don't need to mess around in asm/memory.h with ifdefs to sort this out, so let's get rid of that, and there's no point offering the "Memory split" option for noMMU as that's meaningless there.

This reverts commit 3804fad4. This commit, together with commit 247bf557 "xhci 1.0: Limit arbitrarily-aligned scatter gather." were origially added to get xHCI 1.0 hosts and usb ethernet ax88179_178a devices working together with scatter gather. xHCI 1.0 hosts pose some requirement on how transfer buffers are aligned, setting this requirement for 1.0 hosts caused USB 3.0 mass storage devices to fail more frequently. USB 3.0 mass storage devices used to work before 3.14-rc1. Theoretically, the TD fragment rules could have caused an occasional disk glitch. Now the devices *will* fail, instead of theoretically failing. >From a user perspective, this looks like a regression; the USB device obviously fails on 3.14-rc1, and may sometimes silently fail on prior kernels. The proper soluition is to implement the TD fragment rules for xHCI 1.0 hosts, but for now, revert this patch until scatter gather can be properly supported.
