2016-04-27f2fs: fix to return 0 if err == -ENOENT in f2fs_readdirYunlong Song1-0/+1
Commit 57b62d29ad5b384775974973087d47755a8c6fcc ("f2fs: fix to report error in f2fs_readdir") causes f2fs_readdir to return -ENOENT when get_lock_data_page returns -ENOENT. However, the original logic is to continue when get_lock_data_page returns -ENOENT, but it forgets to reset err to 0. This will cause getdents64 incorretly return -ENOENT when lastdirent is NULL in getdents64. This will lead to a wrong return value for syscall caller.

2016-04-27f2fs: move node pages only in victim section during GCChao Yu3-21/+36
For foreground GC, we cache node blocks in victim section and set them dirty, then we call sync_node_pages to flush these node pages, but meanwhile, those node pages which does not locate in victim section will be flushed together, so more bandwidth and continuous free space would be occupied. So for this condition, it's better to leave those unrelated node page in cache for further write hit, and let CP or VM to flush them afterward.

2016-04-15f2fs: unset atomic/volatile flag in f2fs_release_fileJaegeuk Kim2-3/+4
The atomic/volatile operation should be done in pair of start and commit ioctl. For example, if a killed process remains open-ended atomic operation, we should drop its flag as well as its atomic data. Otherwise, if sqlite initiates another operation which doesn't require atomic writes, it will lose every data, since f2fs still treats with them as atomic writes; nobody will trigger its commit.

2016-04-15f2fs: fix to convert inline directory correctlyChao Yu4-43/+144
With below serials, we will lose parts of dirents: 1) mount f2fs with inline_dentry option 2) echo 1 > /sys/fs/f2fs/sdX/dir_level 3) mkdir dir 4) touch 180 files named [1-180] in dir 5) touch 181 in dir 6) echo 3 > /proc/sys/vm/drop_caches 7) ll dir ls: cannot access 2: No such file or directory ls: cannot access 4: No such file or directory ls: cannot access 5: No such file or directory ls: cannot access 6: No such file or directory ls: cannot access 8: No such file or directory ls: cannot access 9: No such file or directory ... total 360 drwxr-xr-x 2 root root 4096 Feb 19 15:12 ./ drwxr-xr-x 3 root root 4096 Feb 19 15:11 ../ -rw-r--r-- 1 root root 0 Feb 19 15:12 1 -rw-r--r-- 1 root root 0 Feb 19 15:12 10 -rw-r--r-- 1 root root 0 Feb 19 15:12 100 -????????? ? ? ? ? ? 101 -????????? ? ? ? ? ? 102 -????????? ? ? ? ? ? 103 ... The reason is: when doing the inline dir conversion, we didn't consider that directory has hierarchical hash structure which can be configured through sysfs interface 'dir_level'. By default, dir_level of directory inode is 0, it means we have one bucket in hash table located in first level, all dirents will be hashed in this bucket, so it has no problem for us to do the duplication simply between inline dentry page and converted normal dentry page. However, if we configured dir_level with the value N (greater than 0), it will expand the bucket number of first level hash table by 2^N - 1, it hashs dirents into different buckets according their hash value, if we still move all dirents to first bucket, it makes incorrent locating for inline dirents, the result is, although we can iterate all dirents through ->readdir, we can't stat some of them in ->lookup which based on hash table searching. This patch fixes this issue by rehashing dirents into correct position when converting inline directory. Signed-off-by: Chao Yu <chao2.yu@samsung.com> Signed-off-by: Jaegeuk Kim <jaegeuk@kernel.org>

2016-04-14dm cache metadata: fix READ_LOCK macros and cleanup WRITE_LOCK macrosMike Snitzer1-24/+40
The READ_LOCK macro was incorrectly returning -EINVAL if dm_bm_is_read_only() was true -- it will always be true once the cache metadata transitions to read-only by dm_cache_metadata_set_read_only(). Wrap READ_LOCK and WRITE_LOCK multi-statement macros in do {} while(0). Also, all accesses of the 'cmd' argument passed to these related macros are now encapsulated in parenthesis. A follow-up patch can be developed to eliminate the use of macros in favor of pure C code. Avoiding that now given that this needs to apply to stable@.

2016-04-14/proc/iomem: only expose physical resource addresses to privileged usersLinus Torvalds1-2/+11
In commit c4004b02f8e5b ("x86: remove the kernel code/data/bss resources from /proc/iomem") I was hoping to remove the phyiscal kernel address data from /proc/iomem entirely, but that had to be reverted because some system programs actually use it. This limits all the detailed resource information to properly credentialed users instead. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2016-04-14pci-sysfs: use proper file capability helper functionLinus Torvalds1-1/+1
The PCI config access checked the file capabilities correctly, but used the itnernal security capability check rather than the helper function that is actually meant for that. The security_capable() has unusual return values and is not meant to be used elsewhere (the only other use is in the capability checking functions that we actually intend people to use, and this odd PCI usage really stood out when looking around the capability code.

2016-04-14Make file credentials available to the seqfile interfacesLinus Torvalds2-12/+8
A lot of seqfile users seem to be using things like %pK that uses the credentials of the current process, but that is actually completely wrong for filesystem interfaces. The unix semantics for permission checking files is to check permissions at _open_ time, not at read or write time, and that is not just a small detail: passing off stdin/stdout/stderr to a suid application and making the actual IO happen in privileged context is a classic exploit technique. So if we want to be able to look at permissions at read time, we need to use the file open credentials, not the current ones. Normal file accesses can just use "f_cred" (or any of the helper functions that do that, like file_ns_capable()), but the seqfile interfaces do not have any such options. It turns out that seq_file _does_ save away the user_ns information of the file, though. Since user_ns is just part of the full credential information, replace that special case with saving off the cred pointer instead, and suddenly seq_file has all the permission information it needs.

2016-04-14Revert "x86: remove the kernel code/data/bss resources from /proc/iomem"Linus Torvalds1-0/+37
This reverts commit c4004b02f8e5b9ce357a0bb1641756cc86962664. Sadly, my hope that nobody would actually use the special kernel entries in /proc/iomem were dashed by kexec. Which reads /proc/iomem explicitly to find the kernel base address. Nasty. Anyway, that means we can't do the sane and simple thing and just remove the entries, and we'll instead have to mask them out based on permissions.

2016-04-14pwm: fsl-ftm: Use flat regmap cacheStefan Agner1-1/+1
Use flat regmap cache to avoid lockdep warning at probe: [ 0.697285] WARNING: CPU: 0 PID: 1 at kernel/locking/lockdep.c:2755 lockdep_trace_alloc+0x15c/0x160() [ 0.697449] DEBUG_LOCKS_WARN_ON(irqs_disabled_flags(flags)) The RB-tree regmap cache needs to allocate new space on first writes. However, allocations in an atomic context (e.g. when a spinlock is held) are not allowed. The function regmap_write calls map->lock, which acquires a spinlock in the fast_io case. Since the pwm-fsl-ftm driver uses MMIO, the regmap bus of type regmap_mmio is being used which has fast_io set to true. The MMIO space of the pwm-fsl-ftm driver is reasonable condense, hence using the much faster flat regmap cache is anyway the better choice.

2016-04-13ALSA: hda - Fix inconsistent monitor_present state until repollTakashi Iwai1-7/+4
While the previous commit fixed the missing monitor_present flag update, it may be still in an inconsistent state while the driver repolls: the flag itself is updated, but the eld_valid flag and the contents don't follow until the repoll finishes (and may be repeated for a few times). The basic problem is that pin_eld->monitor_present is updated in the caller side. This should have been updated only in update_eld(). So, the proper fix is to avoid accessing pin_eld but only spec->temp_eld. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2016-04-13ALSA: hda - Fix regression of monitor_present flag in eld proc fileHyungwon Hwang1-0/+2
The commit [bd48128539ab: ALSA: hda - Fix forgotten HDMI monitor_present update] covered the missing update of monitor_present flag, but this caused a regression for devices without the i915 eld notifier. Since the old code supposed that pin_eld->monitor_present was updated by the caller side, the hdmi_present_sense_via_verbs() doesn't update the temporary eld->monitor_present but only pin_eld->monitor_present, which is now overridden in update_eld(). The fix is to update pin_eld->monitor_present as well before calling update_eld(). Note that this may still leave monitor_present flag in an inconsistent state when the driver repolls, but this is at least the old behavior. More proper fix will follow in the later patch.
