2014-03-10libata: use wider match for blacklisting Crucial M500Tejun Heo1-2/+1
We're now blacklisting "Crucial_CT???M500SSD1" and "Crucial_CT???M500SSD3". Also, "Micron_M500*" is blacklisted which is about the same devices as the crucial branded ones. Let's merge the two Crucial M500 entries and widen the match to "Crucial_CT???M500SSD*" so that we don't have to fiddle with new entries for similar devices.

2014-03-09KEYS: Make the keyring cycle detector ignore other keyrings of the same nameDavid Howells1-1/+5
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 ...

git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm 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.

2014-03-07x86: fix compile error due to X86_TRAP_NMI use in asm filesLinus Torvalds2-2/+2
It's an enum, not a #define, you can't use it in asm files. Introduced in commit 5fa10196bdb5 ("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).

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

2014-03-07x86: Ignore NMIs that come in during early bootH. Peter Anvin2-2/+11
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 017f161a55b4 (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.

2014-03-07ARM: 7991/1: sa1100: fix compile problem on CollieLinus Walleij1-0/+2
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".

2014-03-07ARM: fix noMMU kallsyms symbol filteringRussell King2-6/+5
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.

2014-03-07usb: Make DELAY_INIT quirk wait 100ms between Get Configuration requestsJulius Werner1-0/+4
The DELAY_INIT quirk only reduces the frequency of enumeration failures with the Logitech HD Pro C920 and C930e webcams, but does not quite eliminate them. We have found that adding a delay of 100ms between the first and second Get Configuration request makes the device enumerate perfectly reliable even after several weeks of extensive testing. The reasons for that are anyone's guess, but since the DELAY_INIT quirk already delays enumeration by a whole second, wating for another 10th of that isn't really a big deal for the one other device that uses it, and it will resolve the problems with these webcams.

2014-03-07usb: Add device quirk for Logitech HD Pro Webcams C920 and C930eJulius Werner1-0/+4
We've encountered a rare issue when enumerating two Logitech webcams after a reboot that doesn't power cycle the USB ports. They are spewing random data (possibly some leftover UVC buffers) on the second (full-sized) Get Configuration request of the enumeration phase. Since the data is random this can potentially cause all kinds of odd behavior, and since it occasionally happens multiple times (after the kernel issues another reset due to the garbled configuration descriptor), it is not always recoverable. Set the USB_DELAY_INIT quirk that seems to work around the issue.

2014-03-07dm space map metadata: fix refcount decrement below 0 which caused corruptionJoe Thornber1-21/+92
This has been a relatively long-standing issue that wasn't nailed down until Teng-Feng Yang's meticulous bug report to dm-devel on 3/7/2014, see: http://www.redhat.com/archives/dm-devel/2014-March/msg00021.html From that report: "When decreasing the reference count of a metadata block with its reference count equals 3, we will call dm_btree_remove() to remove this enrty from the B+tree which keeps the reference count info in metadata device. The B+tree will try to rebalance the entry of the child nodes in each node it traversed, and the rebalance process contains the following steps. (1) Finding the corresponding children in current node (shadow_current(s)) (2) Shadow the children block (issue BOP_INC) (3) redistribute keys among children, and free children if necessary (issue BOP_DEC) Since the update of a metadata block's reference count could be recursive, we will stash these reference count update operations in smm->uncommitted and then process them in a FILO fashion. The problem is that step(3) could free the children which is created in step(2), so the BOP_DEC issued in step(3) will be carried out before the BOP_INC issued in step(2) since these BOPs will be processed in FILO fashion. Once the BOP_DEC from step(3) tries to decrease the reference count of newly shadow block, it will report failure for its reference equals 0 before decreasing. It looks like we can solve this issue by processing these BOPs in a FIFO fashion instead of FILO." Commit 5b564d80 ("dm space map: disallow decrementing a reference count below zero") changed the code to report an error for this temporary refcount decrement below zero. So what was previously a harmless invalid refcount became a hard failure due to the new error path: device-mapper: space map common: unable to decrement a reference count below 0 device-mapper: thin: 253:6: dm_thin_insert_block() failed: error = -22 device-mapper: thin: 253:6: switching pool to read-only mode This bug is in dm persistent-data code that is common to the DM thin and cache targets. So any users of those targets should apply this fix. Fix this by applying recursive space map operations in FIFO order rather than FILO.

2014-03-07firewire: don't use PREPARE_DELAYED_WORKTejun Heo3-11/+29
PREPARE_[DELAYED_]WORK() are being phased out. They have few users and a nasty surprise in terms of reentrancy guarantee as workqueue considers work items to be different if they don't have the same work function. firewire core-device and sbp2 have been been multiplexing work items with multiple work functions. Introduce fw_device_workfn() and sbp2_lu_workfn() which invoke fw_device->workfn and sbp2_logical_unit->workfn respectively and always use the two functions as the work functions and update the users to set the ->workfn fields instead of overriding work functions using PREPARE_DELAYED_WORK(). This fixes a variety of possible regressions since a2c1c57be8d9 "workqueue: consider work function when searching for busy work items" due to which fw_workqueue lost its required non-reentrancy property.
