GFS2: merge window
Here is a list of patches we've accumulated for GFS2 for the current upstream
merge window. There are only six patches this time:
1. A cleanup patch from Andreas to remove the gl_spin #define in favor
of its value for the sake of clarity.
2. A fix from Andy Price to mark the inode dirty during fallocate.
3. A fix from Andy Price to set s_mode on mount failures to prevent
a stack trace.
4. A patch from me to prevent a kernel BUG() in trans_add_meta/trans_add_data
due to uninitialized storage.
5. A patch from me to protecting our freeing of the in-core directory
hash table to prevent double-free.
6. A fix for a page/block rounding problem that resulted in a metadata
coherency problem when the block size != page size.
I've got a lot more patches in various stages of review and testing,
but I'm afraid they'll have to wait until the next merge window. So
next time we're likely to have a lot more.

Move all pointer-formatting documentation to one place in the code and one place in the documentation instead of keeping it in three places with different level of completeness. Documentation/printk-formats.txt has detailed information about each modifier, docstring above pointer() has short descriptions of them (as that is the function dealing with %p) and docstring above vsprintf() is removed as redundant.

mm: make compound_head() robust
Hugh has pointed that compound_head() call can be unsafe in some
context. There's one example:
CPU0 CPU1
isolate_migratepages_block()
page_count()
compound_head()
!!PageTail() == true
put_page()
tail->first_page = NULL
head = tail->first_page
alloc_pages(__GFP_COMP)
prep_compound_page()
tail->first_page = head
__SetPageTail(p);
!!PageTail() == true
<head == NULL dereferencing>
The race is pure theoretical. I don't it's possible to trigger it in
practice. But who knows.
We can fix the race by changing how encode PageTail() and compound_head()
within struct page to be able to update them in one shot.
The patch introduces page->compound_head into third double word block in
front of compound_dtor and compound_order. Bit 0 encodes PageTail() and
the rest bits are pointer to head page if bit zero is set.
The patch moves page->pmd_huge_pte out of word, just in case if an
architecture defines pgtable_t into something what can have the bit 0
set.
hugetlb_cgroup uses page->lru.next in the second tail page to store
pointer struct hugetlb_cgroup. The patch switch it to use page->private
in the second tail page instead. The space is free since ->first_page is
removed from the union.
The patch also opens possibility to remove HUGETLB_CGROUP_MIN_ORDER
limitation, since there's now space in first tail page to store struct
hugetlb_cgroup pointer. But that's out of scope of the patch.
That means page->compound_head shares storage space with:
- page->lru.next;
- page->next;
- page->rcu_head.next;
That's too long list to be absolutely sure, but looks like nobody uses
bit 0 of the word.
page->rcu_head.next guaranteed[1] to have bit 0 clean as long as we use
call_rcu(), call_rcu_bh(), call_rcu_sched(), or call_srcu(). But future
call_rcu_lazy() is not allowed as it makes use of the bit and we can
get false positive PageTail().

mm, page_alloc: distinguish between being unable to sleep, unwilling to sleep and avoiding waking kswapd
__GFP_WAIT has been used to identify atomic context in callers that hold spinlocks or are in interrupts. They are expected to be high priority and have access one of two watermarks lower than "min" which can be referred to as the "atomic reserve". __GFP_HIGH users get access to the first lower watermark and can be called the "high priority reserve". Over time, callers had a requirement to not block when fallback options were available. Some have abused __GFP_WAIT leading to a situation where an optimisitic allocation with a fallback option can access atomic reserves. This patch uses __GFP_ATOMIC to identify callers that are truely atomic, cannot sleep and have no alternative. High priority users continue to use __GFP_HIGH. __GFP_DIRECT_RECLAIM identifies callers that can sleep and are willing to enter direct reclaim. __GFP_KSWAPD_RECLAIM to identify callers that want to wake kswapd for background reclaim. __GFP_WAIT is redefined as a caller that is willing to enter direct reclaim and wake kswapd for background reclaim. This patch then converts a number of sites o __GFP_ATOMIC is used by callers that are high priority and have memory pools for those requests. GFP_ATOMIC uses this flag. o Callers that have a limited mempool to guarantee forward progress clear __GFP_DIRECT_RECLAIM but keep __GFP_KSWAPD_RECLAIM. bio allocations fall into this category where kswapd will still be woken but atomic reserves are not used as there is a one-entry mempool to guarantee progress. o Callers that are checking if they are non-blocking should use the helper gfpflags_allow_blocking() where possible. This is because checking for __GFP_WAIT as was done historically now can trigger false positives. Some exceptions like dm-crypt.c exist where the code intent is clearer if __GFP_DIRECT_RECLAIM is used instead of the helper due to flag manipulations. o Callers that built their own GFP flags instead of starting with GFP_KERNEL and friends now also need to specify __GFP_KSWAPD_RECLAIM. The first key hazard to watch out for is callers that removed __GFP_WAIT and was depending on access to atomic reserves for inconspicuous reasons. In some cases it may be appropriate for them to use __GFP_HIGH. The second key hazard is callers that assembled their own combination of GFP flags instead of starting with something like GFP_KERNEL. They may now wish to specify __GFP_KSWAPD_RECLAIM. It's almost certainly harmless if it's missed in most cases as other activity will wake kswapd.

Most of the changes are clean ups and small fixes. Some of them have
stable tags to them. I searched through my INBOX just as the merge window
opened and found lots of patches to pull. I ran them through all my tests
and they were in linux-next for a few days.
Features added this release:
----------------------------
o Module globbing. You can now filter function tracing to several
modules. # echo '*:mod:*snd*' > set_ftrace_filter (Dmitry Safonov)
o Tracer specific options are now visible even when the tracer is not
active. It was rather annoying that you can only see and modify tracer
options after enabling the tracer. Now they are in the options/ directory
even when the tracer is not active. Although they are still only visible
when the tracer is active in the trace_options file.
o Trace options are now per instance (although some of the tracer specific
options are global)
o New tracefs file: set_event_pid. If any pid is added to this file, then
all events in the instance will filter out events that are not part of
this pid. sched_switch and sched_wakeup events handle next and the wakee
pids.

MTD updates for 4.4-rc1:
Core
* WARN (in some cases) when a struct mtd_info is registered multiple times;
in the past this was "supported", but it's still error prone for future
development. There's only one ugly case of this left in the tree (that
we're aware of) and the owners are aware of the problems there.
* fix potential deadlock in the blkdev removal path
NOTE: the (potential) deadlock was introduced in a for-stable patch. This
one is also marked for -stable.
* ioctl(BLKPG) compat_ioctl support; resolves issues with 32-bit user space
vs. 64-bit kernel space
* Set MTD parent device correctly throughout the tree, so the tree structure
appears correctly in sysfs; many drivers were missing this (soft)
requirement
* Move device tree partitions (ofpart) into a dedicated 'partitions' subnode;
this helps to disambiguate whether a node is a partition or some other
auxiliary data
* Improve error handling for partitioning failures
NAND
* General: Increase timeout period, for corner-case systems with
less-than-accurate jiffies

Pull MTD updates from Brian Norris:
"Core:
- WARN (in some cases) when a struct mtd_info is registered multiple
times; in the past this was "supported", but it's still error prone
for future development. There's only one ugly case of this left in
the tree (that we're aware of) and the owners are aware of the
problems there.
- fix potential deadlock in the blkdev removal path NOTE: the
(potential) deadlock was introduced in a for-stable patch. This
one is also marked for -stable.
- ioctl(BLKPG) compat_ioctl support; resolves issues with 32-bit user
space vs 64-bit kernel space
- Set MTD parent device correctly throughout the tree, so the tree
structure appears correctly in sysfs; many drivers were missing
this (soft) requirement
- Move device tree partitions (ofpart) into a dedicated 'partitions'
subnode; this helps to disambiguate whether a node is a partition
or some other auxiliary data
- Improve error handling for partitioning failures
NAND:
- General: Increase timeout period, for corner-case systems with
less-than-accurate jiffies
- Fix OF-based autoloading of several NAND drivers when built as
modules
- pxa3xx_nand:
- Rework timing configuration to be more dynamic
- Refactor PM support
- brcmnand: prepare for NorthStar 2 support (ARM64, 16-bit NAND
chips)
- sunxi_nand: refactoring and a few bug fixes

sound updates for 4.4-rc1
Here is the first batch of updates for sound system on 4.4-rc1.
Again at this time, the update looks fairly calm; no big changes in
either ALSA core or ASoC infrastructures, rather all small cleanups,
in addition to the new stuff as usual.
The biggest changes are about Firewire sound devices. It gained lots
of new device support, and MIDI functionality. Also there are updates
for a few still working-in-progress stuff (topology API and ASoC
skylake), too. But overall, this update should give no big surprise.
Some highlight is below:
Core:
- A few more Kconfig items for tinification; it's marked as EXPERT,
so normal user should't be bothered :)
- Refactoring with a new PCM hw_constraint helper
- Removal of unused transfer_ack_{begin,end} PCM callbacks
Firewire:
- Restructuring of code subtree, lots of refactoring
- Support AMDTP variants
- New driver for Digidesign 002/003 family
- Adds support for TASCAM FireOne to ALSA OXFW driver
- Add MIDI support to TASCAM and Digi00x devices
HD-Audio:
- Automated modalias generation for codec drivers, finally
- Improvement on heuristics for setting mixer name
- A few fixes for longstanding bugs on Creative CA0132 cards
- Addition of audio rate callback with i915 communication
- Fix suspend issue on recent Dell XPS
- Intel Lewisburg controller support
ASoC:
- Updates to the topology userspace interface
- Big updates to the Renesas support (rcar)
- More updates for supporting Intel Sky Lake systems
- New drivers for Asahi Kasei Microdevices AK4613, Allwinnner A10,
Cirrus Logic WM8998, Dialog DA7219, Nuvoton NAU8825, Rockchip
S/PDIF, and Atmel class D amplifier
USB-Audio:
- A fix for newer Roland MIDI devices
- Quirks and workarounds for Zoom R16/24 device
Misc:
- A few fixes for some old Cirrus CS46xx PCI sound boards
- Yet another fixes for some old ESS Maestro3 PCI sound boards

mm, slub, kasan: enable user tracking by default with KASAN=y
It's recommended to have slub's user tracking enabled with CONFIG_KASAN,
because:
a) User tracking disables slab merging which improves
detecting out-of-bounds accesses.
b) User tracking metadata acts as redzone which also improves
detecting out-of-bounds accesses.
c) User tracking provides additional information about object.
This information helps to understand bugs.
Currently it is not enabled by default. Besides recompiling the kernel
with KASAN and reinstalling it, user also have to change the boot cmdline,
which is not very handy.
Enable slub user tracking by default with KASAN=y, since there is no good
reason to not do this.

Documentation/filesystems/proc.txt: a little tidying
There's an odd line about "Locked" at the head of the description of /proc/meminfo: it seems to have strayed from /proc/PID/smaps, so lead it back there. Move "Swap" and "SwapPss" descriptions down above it, to match the order in the file (though "PageSize"s still undescribed). The example of "Locked: 374 kB" (the same as Pss, neither Rss nor Size) is so unlikely as to be misleading: just make it 0, this is /bin/bash text; which would be "dw" (disabled write) not "de" (do not expand).

mm: rmap use pte lock not mmap_sem to set PageMlocked
KernelThreadSanitizer (ktsan) has shown that the down_read_trylock() of
mmap_sem in try_to_unmap_one() (when going to set PageMlocked on a page
found mapped in a VM_LOCKED vma) is ineffective against races with
exit_mmap()'s munlock_vma_pages_all(), because mmap_sem is not held when
tearing down an mm.
But that's okay, those races are benign; and although we've believed for
years in that ugly down_read_trylock(), it's unsuitable for the job, and
frustrates the good intention of setting PageMlocked when it fails.
It just doesn't matter if here we read vm_flags an instant before or after
a racing mlock() or munlock() or exit_mmap() sets or clears VM_LOCKED: the
syscalls (or exit) work their way up the address space (taking pt locks
after updating vm_flags) to establish the final state.
We do still need to be careful never to mark a page Mlocked (hence
unevictable) by any race that will not be corrected shortly after. The
page lock protects from many of the races, but not all (a page is not
necessarily locked when it's unmapped). But the pte lock we just dropped
is good to cover the rest (and serializes even with
munlock_vma_pages_all(), so no special barriers required): now hold on to
the pte lock while calling mlock_vma_page(). Is that lock ordering safe?
Yes, that's how follow_page_pte() calls it, and how page_remove_rmap()
calls the complementary clear_page_mlock().
This fixes the following case (though not a case which anyone has
complained of), which mmap_sem did not: truncation's preliminary
unmap_mapping_range() is supposed to remove even the anonymous COWs of
filecache pages, and that might race with try_to_unmap_one() on a
VM_LOCKED vma, so that mlock_vma_page() sets PageMlocked just after
zap_pte_range() unmaps the page, causing "Bad page state (mlocked)" when
freed. The pte lock protects against this.
You could say that it also protects against the more ordinary case, racing
with the preliminary unmapping of a filecache page itself: but in our
current tree, that's independently protected by i_mmap_rwsem; and that
race would be why "Bad page state (mlocked)" was seen before commit

max_ptes_swap specifies how many pages can be brought in from swap when collapsing a group of pages into a transparent huge page. /sys/kernel/mm/transparent_hugepage/khugepaged/max_ptes_swap A higher value can cause excessive swap IO and waste memory.

mm: hugetlb: proc: add HugetlbPages field to /proc/PID/status
Currently there's no easy way to get per-process usage of hugetlb pages, which is inconvenient because userspace applications which use hugetlb typically want to control their processes on the basis of how much memory (including hugetlb) they use.

The only way to enable a hardlockup to panic the machine is to set 'nmi_watchdog=panic' on the kernel command line.

kernel/watchdog.c: perform all-CPU backtrace in case of hard lockup
In many cases of hardlockup reports, it's actually not possible to know why it triggered, because the CPU that got stuck is usually waiting on a resource (with IRQs disabled) in posession of some other CPU is holding. IOW, we are often looking at the stacktrace of the victim and not the actual offender. Introduce sysctl / cmdline parameter that makes it possible to have hardlockup detector perform all-CPU backtrace.

- a series of patches to synchronously halt a guest (prerequisite for
IRQ forwarding)
- some tracepoint improvements
- a tweak for the EL2 panic handlers
- some more VGIC cleanups getting rid of redundant state
x86: quite a few changes:
- support for VT-d posted interrupts (i.e. PCI devices can inject
interrupts directly into vCPUs). This introduces a new component (in
virt/lib/) that connects VFIO and KVM together. The same infrastructure
will be used for ARM interrupt forwarding as well.
- more Hyper-V features, though the main one Hyper-V synthetic interrupt
controller will have to wait for 4.5. These will let KVM expose Hyper-V
devices.
- nested virtualization now supports VPID (same as PCID but for vCPUs)
which makes it quite a bit faster
- for future hardware that supports NVDIMM, there is support for clflushopt,
clwb, pcommit
- support for "split irqchip", i.e. LAPIC in kernel + IOAPIC/PIC/PIT in
userspace, which reduces the attack surface of the hypervisor
- obligatory smattering of SMM fixes
- on the guest side, stable scheduler clock support was rewritten to not
require help from the hypervisor.

rework of percpu_rwsem which is scheduled to be merged in this

- On the v2 hierarchy, when controllers are enabled and disabled, all
operations are atomic and can fail and revert cleanly. This allows
->can_attach() failure which is necessary for cpu RT slices.
- Tasks now stay associated with the original cgroups after exit
until released. This allows tracking resources held by zombies
(e.g. pids) and makes it easy to find out where zombies came from
on the v2 hierarchy. The pids controller was broken before these
changes as zombies escaped the limits; unfortunately, updating this
behavior required too many invasive changes and I don't think it's
a good idea to backport them, so the pids controller on 4.3, the
first version which included the pids controller, will stay broken
at least until I'm sure about the cgroup core changes.

regulator: Updates for v4.4
This is quite a quiet release in terms of volume of patches but it
includes a couple of really nice core changes - the work Sascha has done
in particular is something I've wanted to get done for a long time but
just never got round to myself. Highlights include:
- Support from Sascha Hauer for setting the voltage of parent supplies
based on requests from their children. This is used both to allow
set_voltage() to work through a dumb switch and to improve the
efficiency of systems where DCDCs are used to supply LDOs by minimising
the voltage drop over the LDOs.
- Removal of regulator_list by Tomeu Vizoso, meaning we're not
duplicating the device list maintained by the driver core.
- Support for Wolfson/Cirrus WM8998 and WM1818.

The majority of the changes are driver updates and new device
support. The core framework is mostly unchanged this time
around, with only a couple patches to expose a clk provider
API and make getting clk parent names from DT more robust.
Driver updates:
- Support for clock controllers found on Broadcom Northstar
SoCs and bcm2835 SoC
- Support for Allwinner audio clocks
- A few cleanup patches for Tegra drivers and support for the
highest DFLL frequencies on Tegra124
- Samsung exynos7 fixes and improvements
- i.Mx SoC updates to add a few missing clocks and keep debug
uart clocks on during kernel intialization
- Some mediatek cleanups and support for more subsystem clocks
- Support for msm8916 gpu/audio clocks and qcom's GDSC power domain
controllers
- A new driver for the Silabs si514 clock chip

USB patches for 4.4-rc1
Here is the big USB patchset for 4.4-rc1. As usual, most of the changes are in the gadget subsystem, and we removed a host controller for a device that is no longer in existance, and probably never was even made public. There is also other minor driver updates and new device ids, full details in the changelog. All of these have been in linux-next for a while.

- Revert a dm-multipath change that caused a regression for unprivledged
users (e.g. kvm guests) that issued ioctls when a multipath device had
no available paths.
- Include Christoph's refactoring of DM's ioctl handling and add support
for passing through persistent reservations with DM multipath.
- All other changes are very simple cleanups.
