During an unexpected shutdown, references to tid_rb_node were NULL'ed out
without properly being released.
Fix this by calling clear_tid_node in the mmu notifier remove callback
rather than after these callbacks are called.

The ops->remove() callback was called by hfi1_mmu_unregister() with a
NULL mm argument while holding a spinlock. In the case of sdma_rb_remove()
this caused it to pass current->mm to hfi1_release_user_pages()
This had 2 problems. First this would attempt to acquire the mmap_sem
under a spin lock. Second the use of current->mm is not always guaranteed
to be the proper mm when the fd is being closed.
Rather than depend on this implicit behavior we move all calls to
ops->remove outside of the spinlock. This also allows the correct
mm to be used in the remove callback without fear of deadlock.
Because the MMU notifier is not guaranteed to hold mm->mmap_sem, but
usually does, we must delay all remove callbacks until out of the notifier,
when the callbacks can take the mmap_sem if they need to.
Code comments were added to clarify what the expectations are for the
users of the mmu rb tree.

Per file descriptor TID caching actions depend on a global that can
change midway through the lifetime of that file descriptor.
Make the use of caching consistent for the life of the file descriptor

The objects which use cache handling should reference their own handler
object not the internal data structure it uses to track the nodes.
Have the "users" of the mmu notifier code pass opaque objects which can
then be properly used in the mmu callbacks depending on the owners needs.
This patch has the additional benefit that operations no longer require a
look up in a list to find the handlers.

The hfi1 driver registers a mmu_notifier callback when /dev/hfi1_* is
opened, and unregisters it when the device is closed. The driver
incorrectly assumes that the close will always happen from the same
context as the open. In particular, closes due to SIGKILL or OOM killer
activity may happen from a different context. In these cases, the wrong
mm is passed to mmu_notifier_unregister(), which causes improper reference
counting for the victim mm, and eventual memory corruption.
Preserve the mm for all open file descriptors and use this mm rather than
current->mm for memory operations for the lifetime of that fd. Note: this
patch leaves 1 use of current->mm in place. This use is removed in a
follow on patch because other functional changes were required prior to
that use being removed.
If registration fails, there is no reason to keep the handler object
around. Free the handler object rather than add it to the list to
prevent any mmu_notifier operations, including unregister, when
registration fails.

The driver pads non-double word multiple message sizes but it doesn't
account for this padding when the packet length is calculated. Also, the
data length is miscalculated for message sizes less than 4 bytes due to
the bit representation in LRH. And there's a check for non-double word
multiple message sizes that prevents these messages from being sent.
This patch fixes length miscalculations and enables the functionality to
send non-double word multiple message sizes.

kzalloc() which identified the problem.
While fixing this issue 2 other bugs were noticed. First, the array

it is allocated. Second, kernel_send_context was not released on error.

Pull orangefs update from Martin Brandenburg:
"Kernel side caching and executable bugfix
This allows OrangeFS to utilize the dcache and adds an in kernel
attribute cache. We previously used the user side client for this
purpose.
We see a modest performance increase on small file operations. For
example, without the cache, compiling coreutils takes about 17
minutes. With the patch and a 50 millisecond timeout for
dcache_timeout_msecs and getattr_timeout_msecs (the default),
compiling coreutils takes about 6 minutes 20 seconds. On the same
hardware, compiling coreutils on an xfs filesystem takes 90 seconds.
We see similar improvements with mdtest and a test involving writing,
reading, and deleting a large number of small files.
Interested parties can review more data at the following URL.
https://docs.google.com/spreadsheets/d/1v4aUeppKexIbRMz_Yn9k4eaM3uy2KCaPoe_93YKWOtA/pubhtml
The eventual goal of this is to allow getdents to turn into a
readdirplus to the OrangeFS server. The cache will be filled then,
which should provide a performance benefit to the common case of
readdir followed by getattr on each entry (i.e. ls -l).
This also fixes a bug. When orangefs_inode_permission was added, it
did not collect i_size from the OrangeFS server, since this presses an
unnecessary load on the OrangeFS server. However, it left a case
where i_size is never initialized. Then running an executable could
fail.
With this patch, size is always collected to be inserted into the
cache. Thus the bug disappears. If this patch is not accepted during
this merge window, we will send a one-line band-aid for this bug
instead"

For more targeted fuzzing, it's better to disable kernel-wide
instrumentation and instead enable it on a per-subsystem basis. This
follows the pattern of UBSAN and allows you to compile in the kcov
driver without instrumenting the whole kernel.
To instrument a part of the kernel, you can use either
# for a single file in the current directory
KCOV_INSTRUMENT_filename.o := y
or
# for all the files in the current directory (excluding subdirectories)
KCOV_INSTRUMENT := y
or
# (same as above)
ccflags-y += $(CFLAGS_KCOV)
or
# for all the files in the current directory (including subdirectories)
subdir-ccflags-y += $(CFLAGS_KCOV)

It doesn't trim just symbols that are totally unused in-tree - it trims
the symbols unused by any in-tree modules actually built. If you've
done a 'make localmodconfig' and only build a hundred or so modules,

something...
Hopefully this will save the next guy from a Homer Simpson "D'oh!"

Doing patches with allmodconfig kernel compiled and committing stuff
into local tree have unfortunate consequence: kernel version changes (as
it should) leading to recompiling and relinking of several files even if
they weren't touched (or interesting at all). This and "git-whatever"
figuring out current version slow down compilation for no good reason.
But lets face it, "allmodconfig" kernels don't care about kernel
version, they are simply compile check guinea pigs.
Make LOCALVERSION_AUTO depend on !COMPILE_TEST, so it doesn't sneak into
allmodconfig .config.

Commit 20d8b67c06fa ("relay: add buffer-only channels; useful for early
logging") added support to use channels with no associated files.
This is useful when the exact location of relay file is not known or the
the parent directory of relay file is not available, while creating the
channel and the logging has to start right from the boot.
But there was no provision to use global mode with buffer-only channels,
which is added by this patch, without modifying the interface where
initially there will be a dummy invocation of create_buf_file callback
through which kernel client can convey the need of a global buffer.
For the use case where drivers/kernel clients want a simple interface
for the userspace, which enables them to capture data/logs from relay
file inorder & without any post processing, support of Global buffer
mode is warranted.
Modules, like i915, using relay_open() in early init would have to later
register their buffer-only relays, once debugfs is available, by calling
relay_late_setup_files(). Hence relay_late_setup_files() symbol also
needs to be exported.

Commit e93762bbf681 ("w1: masters: omap_hdq: add support for 1-wire
mode") added a statement to clear the hdq_irqstatus flags in
hdq_read_byte().
If the hdq reading process is scheduled slowly or interrupts are
disabled for a while the hardware read activity might already be
finished on entry of hdq_read_byte(). And hdq_isr() already has set the
hdq_irqstatus to 0x6 (can be seen in debug mode) denoting that both, the
TXCOMPLETE and RXCOMPLETE interrupts occurred in parallel.
This means there is no need to wait and the hdq_read_byte() can just
read the byte from the hdq controller.
By resetting hdq_irqstatus to 0 the read process is forced to be always
waiting again (because the if statement always succeeds) but the
hardware will not issue another RXCOMPLETE interrupt. This results in a
false timeout.
After such a situation the hdq bus hangs.
