2016-09-12staging: ks7010: return on failureSudip Mukherjee1-4/+2
On failure we were jumping to error_out0 where we were trying sdio_release_host() but at this point of execution we still have not done sdio_claim_host() and as a result host->claimed can still be 0. And if host->claimed is 0 then WARN_ON(!host->claimed) will give a warning. Moreover, if it is still not claimed then mmc_host->claim_cnt will be 0 and mmc_release_host() will do "if (--host->claim_cnt)" and thus the condition will become true. Lets just return the value on allocation failure instead of trying to release the host before claiming it.

2016-09-10fscrypto: require write access to mount to set encryption policyEric Biggers4-25/+29
Since setting an encryption policy requires writing metadata to the filesystem, it should be guarded by mnt_want_write/mnt_drop_write. Otherwise, a user could cause a write to a frozen or readonly filesystem. This was handled correctly by f2fs but not by ext4. Make fscrypt_process_policy() handle it rather than relying on the filesystem to get it right.

2016-09-09fscrypto: only allow setting encryption policy on directoriesEric Biggers1-0/+2
The FS_IOC_SET_ENCRYPTION_POLICY ioctl allowed setting an encryption policy on nondirectory files. This was unintentional, and in the case of nonempty regular files did not behave as expected because existing data was not actually encrypted by the ioctl. In the case of ext4, the user could also trigger filesystem errors in ->empty_dir(), e.g. due to mismatched "directory" checksums when the kernel incorrectly tried to interpret a regular file as a directory. This bug affected ext4 with kernels v4.8-rc1 or later and f2fs with kernels v4.6 and later. It appears that older kernels only permitted directories and that the check was accidentally lost during the refactoring to share the file encryption code between ext4 and f2fs. This patch restores the !S_ISDIR() check that was present in older kernels. Signed-off-by: Eric Biggers <ebiggers@google.com> Cc: stable@vger.kernel.org Signed-off-by: Theodore Ts'o <tytso@mit.edu>
2016-09-09fscrypto: add authorization check for setting encryption policyEric Biggers1-0/+3
On an ext4 or f2fs filesystem with file encryption supported, a user could set an encryption policy on any empty directory(*) to which they had readonly access. This is obviously problematic, since such a directory might be owned by another user and the new encryption policy would prevent that other user from creating files in their own directory (for example). Fix this by requiring inode_owner_or_capable() permission to set an encryption policy. This means that either the caller must own the file, or the caller must have the capability CAP_FOWNER. (*) Or also on any regular file, for f2fs v4.6 and later and ext4 v4.8-rc1 and later; a separate bug fix is coming for that.

2016-09-09libnvdimm: allow legacy (e820) pmem region to clear bad blocksDave Jiang1-1/+5
Bad blocks can be injected via /sys/block/pmemN/badblocks. In a situation where legacy pmem is being used or a pmem region created by using memmap kernel parameter, the injected bad blocks are not cleared due to nvdimm_clear_poison() failing from lack of ndctl function pointer. In this case we need to just return as handled and allow the bad blocks to be cleared rather than fail.

2016-09-09mm: fix cache mode of dax pmd mappingsDan Williams2-7/+19
track_pfn_insert() in vmf_insert_pfn_pmd() is marking dax mappings as uncacheable rendering them impractical for application usage. DAX-pte mappings are cached and the goal of establishing DAX-pmd mappings is to attain more performance, not dramatically less (3 orders of magnitude). track_pfn_insert() relies on a previous call to reserve_memtype() to establish the expected page_cache_mode for the range. While memremap() arranges for reserve_memtype() to be called, devm_memremap_pages() does not. So, teach track_pfn_insert() and untrack_pfn() how to handle tracking without a vma, and arrange for devm_memremap_pages() to establish the write-back-cache reservation in the memtype tree.

That patch ended up causing off-by-1 error in our TRB accounting logic. Thankfully John Youn found out the problem and we provided a revert to the bogus dwc3 patch in no time. Apart from this off-by-1 error, we have two fixes to the Renesas drivers, a small fix to our generic phy driver, a NULL pointer dereference fix for f_eem and a build warning fix in dwc3.

We have a big rework of the kxsd9 driver queued up behind the fix below and a fix for a recent fix that was marked for stable. Hence this fix series is perhaps a little more urgent than average for IIO. * core - a fix for a fix in the last set. The recent fix for blocking ops when ! task running left a path (unlikely one) in which the function return value was not set - so initialise it to 0. - The IIO_TYPE_FRACTIONAL code previously didn't cope with negative fractions. Turned out a fix for this was in Analog's tree but hadn't made it upstream. * bmc150 - reset chip at init time. At least one board out there ends up coming up in an unstable state due to noise during power up. The reset does no harm on other boards. * kxsd9 - Fix a bug in the reported scaling due to failing to set the integer part to 0. * hid-sensors-pressure - Output was in the wrong units to comply with the IIO ABI. * tools - iio_generic_buffer: Fix the trigger-less mode by ensuring we don't fault out for having no trigger when we explicitly said we didn't want to have one.
2016-09-09arm64: use preempt_disable_notrace in _percpu_read/writeChunyan Zhang1-4/+4
When debug preempt or preempt tracer is enabled, preempt_count_add/sub() can be traced by function and function graph tracing, and preempt_disable/enable() would call preempt_count_add/sub(), so in Ftrace subsystem we should use preempt_disable/enable_notrace instead. In the commit 345ddcc882d8 ("ftrace: Have set_ftrace_pid use the bitmap like events do") the function this_cpu_read() was added to trace_graph_entry(), and if this_cpu_read() calls preempt_disable(), graph tracer will go into a recursive loop, even if the tracing_on is disabled. So this patch change to use preempt_enable/disable_notrace instead in this_cpu_read(). Since Yonghui Yang helped a lot to find the root cause of this problem, so also add his SOB.

2016-09-09arm64: spinlocks: implement smp_mb__before_spinlock() as smp_mb()Will Deacon1-0/+10
smp_mb__before_spinlock() is intended to upgrade a spin_lock() operation to a full barrier, such that prior stores are ordered with respect to loads and stores occuring inside the critical section. Unfortunately, the core code defines the barrier as smp_wmb(), which is insufficient to provide the required ordering guarantees when used in conjunction with our load-acquire-based spinlock implementation. This patch overrides the arm64 definition of smp_mb__before_spinlock() to map to a full smp_mb().
