The rfc4106 encrypy/decrypt helper functions cause an annoying false-positive warning in allmodconfig if we turn on -Wmaybe-uninitialized warnings again: arch/x86/crypto/aesni-intel_glue.c: In function ‘helper_rfc4106_decrypt’: include/linux/scatterlist.h:67:31: warning: ‘dst_sg_walk.sg’ may be used uninitialized in this function [-Wmaybe-uninitialized] The problem seems to be that the compiler doesn't track the state of the 'one_entry_in_sg' variable across the kernel_fpu_begin/kernel_fpu_end section. This takes the easy way out by adding a bogus initialization, which should be harmless enough to get the patch into v4.9 so we can turn on this warning again by default without producing useless output. A follow-up patch for v4.10 rearranges the code to make the warning go away. Signed-off-by: NArnd Bergmann <arnd@arndb.de> Signed-off-by: NLinus Torvalds <torvalds@linux-foundation.org>

Traditionally, we have always had warnings about uninitialized variables enabled, as this is part of -Wall, and generally a good idea [1], but it also always produced false positives, mainly because this is a variation of the halting problem and provably impossible to get right in all cases [2]. Various people have identified cases that are particularly bad for false positives, and in commit e74fc973 ("Turn off -Wmaybe-uninitialized when building with -Os"), I turned off the warning for any build that was done with CC_OPTIMIZE_FOR_SIZE. This drastically reduced the number of false positive warnings in the default build but unfortunately had the side effect of turning the warning off completely in 'allmodconfig' builds, which in turn led to a lot of warnings (both actual bugs, and remaining false positives) to go in unnoticed. With commit 877417e6 ("Kbuild: change CC_OPTIMIZE_FOR_SIZE definition") enabled the warning again for allmodconfig builds in v4.7 and in v4.8-rc1, I had finally managed to address all warnings I get in an ARM allmodconfig build and most other maybe-uninitialized warnings for ARM randconfig builds. However, commit 6e8d666e ("Disable "maybe-uninitialized" warning globally") was merged at the same time and disabled it completely for all configurations, because of false-positive warnings on x86 that I had not addressed until then. This caused a lot of actual bugs to get merged into mainline, and I sent several dozen patches for these during the v4.9 development cycle. Most of these are actual bugs, some are for correct code that is safe because it is only called under external constraints that make it impossible to run into the case that gcc sees, and in a few cases gcc is just stupid and finds something that can obviously never happen. I have now done a few thousand randconfig builds on x86 and collected all patches that I needed to address every single warning I got (I can provide the combined patch for the other warnings if anyone is interested), so I hope we can get the warning back and let people catch the actual bugs earlier. This reverts the change to disable the warning completely and for now brings it back at the "make W=1" level, so we can get it merged into mainline without introducing false positives. A follow-up patch enables it on all levels unless some configuration option turns it off because of false-positives.

When we iterate a master's config entries, what we generally care about is the entry's stream map index, rather than the entry index itself, so it's nice to have the iterator automatically assign the former from the latter. Unfortunately, booting with KASAN reveals the oversight that using a simple comma operator results in the entry index being dereferenced before being checked for validity, so we always access one element past the end of the fwspec array. Flip things around so that the check always happens before the index may be dereferenced.

We now delay installing our per-bus iommu_ops until we know an SMMU has successfully probed, as they don't serve much purpose beforehand, and doing so also avoids fights between multiple IOMMU drivers in a single kernel. However, the upshot of passing the return value of bus_set_iommu() back from our probe function is that if there happens to be more than one SMMUv3 device in a system, the second and subsequent probes will wind up returning -EBUSY to the driver core and getting torn down again. Avoid re-setting ops if ours are already installed, so that any genuine failures stand out.

The 32-bit ARM DMA configuration code predates the IOMMU core's default domain functionality, and instead relies on allocating its own domains and attaching any devices using the generic IOMMU binding to them. Unfortunately, it does this relatively early on in the creation of the device, before we've seen our add_device callback, which leads us to attempt to operate on a half-configured master. To avoid a crash, check for this situation on attach, but refuse to play, as there's nothing we can do. This at least allows VFIO to keep working for people who update their 32-bit DTs to the generic binding, albeit with a few (innocuous) warnings from the DMA layer on boot.

Currently the ALSA proc handler allows read or write even if the proc file were write-only or read-only. It's mostly harmless, does thing but allocating memory and ignores the input/output. But it doesn't tell user about the invalid use, and it's confusing and inconsistent in comparison with other proc files. This patch adds some sanity checks and let the proc handler returning an -EIO error when the invalid read/write is performed.

The ALSA proc handler allows currently the write in the unlimited size until kmalloc() fails. But basically the write is supposed to be only for small inputs, mostly for one line inputs, and we don't have to handle too large sizes at all. Since the kmalloc error results in the kernel warning, it's better to limit the size beforehand. This patch adds the limit of 16kB, which must be large enough for the currently existing code.

Commit 345ddcc8 ("ftrace: Have set_ftrace_pid use the bitmap like events do") added a couple of this_cpu_read calls to the ftrace code. On x86 this is not a problem, since it has single instructions to read percpu data. Other architectures which use the generic variant now have additional preempt_disable and preempt_enable calls in the core ftrace code. This may lead to recursive calls and in result to a dead machine, e.g. if preemption and debugging options are enabled. To fix this use the notrace variant of preempt_disable and preempt_enable within the generic percpu code.

Invalid IP-over-1394 encapsulation headers could trigger buffer overflows (CVE 2016-8633). - IP-over-1394 link fragmentation headers were read and written incorrectly, breaking fragmented RX/TX with other OS's stacks. * tag 'firewire-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/ieee1394/linux1394: firewire: net: fix fragmented datagram_size off-by-one firewire: net: guard against rx buffer overflows

Pull MTD fixes from Brian Norris: - MAINTAINERS updates to reflect some new maintainers/submaintainers. We have some great volunteers who've been developing and reviewing already. We're going to try a group maintainership model, so eventually you'll probably see pull requests from people besides me. - NAND fixes from Boris: "Three simple fixes: - fix a non-critical bug in the gpmi driver - fix a bug in the 'automatic NAND timings selection' feature introduced in 4.9-rc1 - fix a false positive uninitialized-var warning" * tag 'for-linus-20161104' of git://git.infradead.org/linux-mtd: mtd: mtk: avoid warning in mtk_ecc_encode mtd: nand: Fix data interface configuration logic mtd: nand: gpmi: disable the clocks on errors MAINTAINERS: add more people to the MTD maintainer team MAINTAINERS: add a maintainer for the SPI NOR subsystem

由 Ooi, Joyce 提交于
User is unable to access to input-X-yyy and feature-X-yyy where X is a hex value and more than 9 (e.g. input-a-yyy, feature-b-yyy) in HID sensor custom sysfs interface. This is because when creating the attribute, the attribute index is written to using %x (hex). However, when reading and writing values into the attribute, the attribute index is scanned using %d (decimal). Hence, user is unable to access to attributes with index in hex values (e.g. 'a', 'b', 'c') but able to access to attributes with index in decimal values (e.g. 1, 2, 3,..). This fix will change input-%d-%x-%s and feature-%d-%x-%s to input-%x-%x-%s and feature-%x-%x-%s in show_values() and store_values() accordingly.
