When I forced to enable atomic operations intentionally, I could hit the below
panic, since we didn't clear page->private in f2fs_invalidate_page called by

The panic occurs due to NULL mapping having page->private.

commit fde872682e175743e0c3ef939c89e3c6008a1529 upstream.
Some time back, nfsd switched from calling vfs_fsync() to using a new
commit_metadata() hook in export_operations(). If the file system did
not provide a commit_metadata() hook, it fell back to using
sync_inode_metadata(). Unfortunately doesn't work on all file
systems. In particular, it doesn't work on ext4 due to how the inode
gets journalled --- the VFS writeback code will not always call
ext4_write_inode().
So we need to provide our own ext4_nfs_commit_metdata() method which
calls ext4_write_inode() directly.

[ Upstream commit 91633eed73a3ac37aaece5c8c1f93a18bae616a9 ]
So far only CLOCK_MONOTONIC and CLOCK_REALTIME were taken into account as
well as HRTIMER_MODE_ABS/REL in the hrtimer_init tracepoint. The query for
detecting the ABS or REL timer modes is not valid anymore, it got broken
by the introduction of HRTIMER_MODE_PINNED.
HRTIMER_MODE_PINNED is not evaluated in the hrtimer_init() call, but for the
sake of completeness print all given modes.

trace_xen_mmu_flush_tlb{_all}
commit 45dd9b0666a162f8e4be76096716670cf1741f0e upstream.
Doing an audit of trace events, I discovered two trace events in the xen
subsystem that use a hack to create zero data size trace events. This is not
what trace events are for. Trace events add memory footprint overhead, and
if all you need to do is see if a function is hit or not, simply make that
function noinline and use function tracer filtering.
Worse yet, the hack used was:
__array(char, x, 0)
Which creates a static string of zero in length. There's assumptions about
such constructs in ftrace that this is a dynamic string that is nul
terminated. This is not the case with these tracepoints and can cause
problems in various parts of ftrace.
Nuke the trace events!

We get a build error in the irqsoff tracer in some configurations:
kernel/trace/trace_irqsoff.c: In function 'trace_preempt_on':
kernel/trace/trace_irqsoff.c:855:2: error: implicit declaration of function 'trace_preempt_enable_rcuidle'; did you mean 'trace_irq_enable_rcuidle'? [-Werror=implicit-function-declaration]
trace_preempt_enable_rcuidle(a0, a1);
The problem is that trace_preempt_enable_rcuidle() has different
definition based on multiple Kconfig symbols, but not all combinations
have a valid definition.
This changes the conditions so that we always get exactly one
definition of each of the four tracing macros. I have not tried
to verify that these definitions are sensible, but now we
can build all randconfig combinations again.

[ Upstream commit 975b820b6836b6b6c42fb84cd2e772e2b41bca67 ]
In some cases the clock parent would be set NULL when doing re-parent,
it will cause a NULL pointer accessing if clk_set trace event is
enabled.
This patch sets the parent as "none" if the input parameter is NULL.
Fixes: dfc202ead312 (clk: Add tracepoints for hardware operations)

Pull f2fs updates from Jaegeuk Kim:
"In this round, we've followed up to support some generic features such
as cgroup, block reservation, linking fscrypt_ops, delivering
write_hints, and some ioctls. And, we could fix some corner cases in
terms of power-cut recovery and subtle deadlocks.
Enhancements:
- bitmap operations to handle NAT blocks
- readahead to improve readdir speed
- switch to use fscrypt_*
- apply write hints for direct IO
- add reserve_root=%u,resuid=%u,resgid=%u to reserve blocks for root/uid/gid
- modify b_avail and b_free to consider root reserved blocks
- support cgroup writeback
- support FIEMAP_FLAG_XATTR for fibmap
- add F2FS_IOC_PRECACHE_EXTENTS to pre-cache extents
- add F2FS_IOC_{GET/SET}_PIN_FILE to pin LBAs for data blocks
- support inode creation time
Bug fixs:
- sysfile-based quota operations
- memory footprint accounting
- allow to write data on partial preallocation case
- fix deadlock case on fallocate
- fix to handle fill_super errors
- fix missing inode updates of fsync'ed file
- recover renamed file which was fsycn'ed before
- drop inmemory pages in corner error case
- keep last_disk_size correctly
- recover missing i_inline flags during roll-forward
Various clean-up patches were added as well"

commit e39d200fa5bf5b94a0948db0dae44c1b73b84a56 upstream.
Reported by syzkaller:
BUG: KASAN: stack-out-of-bounds in write_mmio+0x11e/0x270 [kvm]
Read of size 8 at addr ffff8803259df7f8 by task syz-executor/32298

The path of patched vmmcall will patch 3 bytes opcode 0F 01 C1(vmcall)
to the guest memory, however, write_mmio tracepoint always prints 8 bytes
through *(u64 *)val since kvm splits the mmio access into 8 bytes. This
leaks 5 bytes from the kernel stack (CVE-2017-17741). This patch fixes
it by just accessing the bytes which we operate on.
Before patch:
syz-executor-5567 [007] .... 51370.561696: kvm_mmio: mmio write len 3 gpa 0x10 val 0x1ffff10077c1010f
After patch:
syz-executor-13416 [002] .... 51302.299573: kvm_mmio: mmio write len 3 gpa 0x10 val 0xc1010f

There is no guarantee that either the request or the svc_xprt exist

Pull f2fs updates from Jaegeuk Kim:
"In this round, we introduce sysfile-based quota support which is
required for Android by default. In addition, we allow that users are
able to reserve some blocks in runtime to mitigate performance drops
in low free space.
Enhancements:
- assign proper data segments according to write_hints given by user
- issue cache_flush on dirty devices only among multiple devices
- exploit cp_error flag and add more faults to enhance fault
injection test
- conduct more readaheads during f2fs_readdir
- add a range for discard commands
Bug fixes:
- fix zero stat->st_blocks when inline_data is set
- drop crypto key and free stale memory pointer while evict_inode is
failing
- fix some corner cases in free space and segment management
- fix wrong last_disk_size
This series includes lots of clean-ups and code enhancement in terms
of xattr operations, discard/flush command control. In addition, it
adds versatile debugfs entries to monitor f2fs status"

It is preferable that WALT window rollover occurs just
before a tick, since the tick is an opportune moment
to record a complete window's statistics, as well as report
those stats to the cpu frequency governor. When CONFIG_HZ
results in a TICK_NSEC that isn't a integral number, this
requirement may be violated. Account for this by reducing
the WALT window size to the nearest multiple of TICK_NSEC.
Commit d368c6faa19b ("sched: walt: fix window misalignment
when HZ=300") attempted to do this but WALT isn't using
MIN_SCHED_RAVG_WINDOW as the window size and the patch was
doing nothing.
Also, change the type of 'walt_disabled' to bool and warn
if an invalid window size causes WALT to be disabled.

There's no need for a separate hierarchy of notifiers, APIs
and variables in walt.c for the purpose of applying frequency
and IPC invariance. Let's just use capacity_curr_of and get
rid of a lot of the infrastructure relating to capacity,
load_scale_factor etc.

Code closed in ifdef CONFIG_SCHED_WALT blocks is not used in
msm-4.4 builds, hence in order to be as much as closer to
upstream and subsequently to have less merge conflicts in the
future, let's restore this code.
Restore below CONFIG_SCHED_WALT changes in file [1]:
3c5c4e9 trace/sched: add rq utilization signal for WALT
3a29814 sched: fix wrong truncation of walt_avg
efb86bd sched: Introduce Window Assisted Load Tracking (WALT)
[1] include/trace/events/sched.h
The above changes were discarded during android-4.4 merging
into msm-4.4 starting from change 1758716.

Preempt and irq trace events can be used for tracing the start and
end of an atomic section which can be used by a trace viewer like
systrace to graphically view the start and end of an atomic section and
correlate them with latencies and scheduling issues.
This also serves as a prelude to using synthetic events or probes to
rewrite the preempt and irqsoff tracers, along with numerous benefits of
using trace events features for these events.
