As part of on ongoing effort to perform more automated testing and
provide more tools for individual developers to validate their
patches before submitting, we are trying to make our code
"clang-format clean". My hope is that once we have fixed all of our
style "quirks", developers will be able to run clang-format on their
patches to help avoid silly formatting problems and ensure their
changes fit in well with the rest of the SELinux kernel code.

A trivial correction to convert an 'unsigned' parameter into an
'unsigned int' parameter so the prototype matches the function
definition.
I really thought that someone submitted a patch for this a few years
ago but sadly I can't find it now.

Eric Paris is an important part of SELinux history and we are all
thankful not only for his stint as maintainer, but his numerous
contributions over the years. Unfortunately for us, Eric has moved
on to other things and hasn't contributed to the SELinux community in
several years (his last SELinux kernel commit was in 2013) so it's
time to officially drop Eric as a maintainer.
I also want to get ahead of any claims of impropriety and state that
this change has absolutely nothing to do with commit 2be4d74f2fd4 ;)
Thanks for all you've done Eric, you'll always be welcome back.

As there were bugs found with the ownership of eventfs dynamic file
creation. Add a test to test it.
It will remount tracefs with a different gid and check the ownership of
the eventfs directory, as well as the system and event directories. It
will also check the event file directories.
It then does a chgrp on each of these as well to see if they all get
updated as expected.
Then it remounts the tracefs file system back to the original group and
makes sure that all the updated files and directories were reset back to
the original ownership.
It does the same for instances that change the ownership of he instance
directory.
Note, because the uid is not reset by a remount, it is tested for every
file by switching it to a new owner and then back again.

It was reported that when mounting the tracefs file system with a gid
other than root, the ownership did not carry down to the eventfs directory
due to the dynamic nature of it.
A fix was done to solve this, but it had two issues.
(a) if the attr passed into update_inode_attr() was NULL, it didn't do
anything. This is true for files that have not had a chown or chgrp
done to itself or any of its sibling files, as the attr is allocated
for all children when any one needs it.
# umount /sys/kernel/tracing
# mount -o rw,seclabel,relatime,gid=1000 -t tracefs nodev /mnt
# ls -ld /mnt/events/sched
drwxr-xr-x 28 root rostedt 0 Dec 21 13:12 /mnt/events/sched/
# ls -ld /mnt/events/sched/sched_switch
drwxr-xr-x 2 root rostedt 0 Dec 21 13:12 /mnt/events/sched/sched_switch/
But when checking the files:
# ls -l /mnt/events/sched/sched_switch
total 0
-rw-r----- 1 root root 0 Dec 21 13:12 enable
-rw-r----- 1 root root 0 Dec 21 13:12 filter
-r--r----- 1 root root 0 Dec 21 13:12 format
-r--r----- 1 root root 0 Dec 21 13:12 hist
-r--r----- 1 root root 0 Dec 21 13:12 id
-rw-r----- 1 root root 0 Dec 21 13:12 trigger
(b) When the attr does not denote the UID or GID, it defaulted to using
the parent uid or gid. This is incorrect as changing the parent
uid or gid will automatically change all its children.
# chgrp tracing /mnt/events/timer
# ls -ld /mnt/events/timer

At first it was thought that this could be easily fixed by just making the
default ownership of the superblock when it was mounted. But this does not
handle the case of:
# chgrp tracing instances
# mkdir instances/foo
If the superblock was used, then the group ownership would be that of what
it was when it was mounted, when it should instead be "tracing".
Instead, set a flag for the top level eventfs directory ("events") to flag
which eventfs_inode belongs to it.
Since the "events" directory's dentry and inode are never freed, it does
not need to use its attr field to restore its mode and ownership. Use the
this eventfs_inode's attr as the default ownership for all the files and
directories underneath it.
When the events eventfs_inode is created, it sets its ownership to its
parent uid and gid. As the events directory is created at boot up before
it gets mounted, this will always be uid=0 and gid=0. If it's created via
an instance, then it will take the ownership of the instance directory.
When the file system is mounted, it will update all the gids if one is
specified. This will have a callback to update the events evenfs_inode's
default entries.
When a file or directory is created under the events directory, it will
walk the ei->dentry parents until it finds the evenfs_inode that belongs
to the events directory to retrieve the default uid and gid values.

* Raw NAND
The most meaningful change being the conversion of the brcmnand driver
to the ->exec_op() API, this series brought additional changes to the
core in order to help controller drivers to handle themselves the WP pin
during destructive operations when relevant.
As always, there is as well a whole bunch of miscellaneous W=1 fixes,
together with a few runtime fixes (double free, timeout value, OOB
layout, missing register initialization) and the usual load of remove
callbacks turned into void (which led to switch the txx9ndfmc driver to
use module_platform_driver()).

SPI NOR comes with die erase support for multi die flashes, with new
octal protocols (1-1-8 and 1-8-8) parsed from SFDP and with an updated
documentation about what the contributors shall consider when proposing
flash additions or updates. Michael Walle stepped out from the reviewer
role to maintainer.

The current logic is probably fine but is a bit convoluted. Plus, we
don't want partial pages to be part of the sequential operation just in
case the core would optimize the page read with a subpage read (which
would break the sequence). This may happen on the first and last page
only, so if the start offset or the end offset is not aligned with a
page boundary, better avoid them to prevent any risk.

Some devices support sequential reads when using the on-die ECC engines,
some others do not. It is a bit hard to know which ones will break other
than experimentally, so in order to avoid such a difficult and painful
task, let's just pretend all devices should avoid using this
optimization when configured like this.

A couple of reports pointed at some strange failures happening a bit
randomly since the introduction of sequential page reads support. After
investigation it turned out the most likely reason for these issues was
the fact that sometimes a (longer) read might happen, starting at the
same page that was read previously. This is optimized by the raw NAND
core, by not sending the READ_PAGE command to the NAND device and just
reading out the data in a local cache. When this page is also flagged as
being the starting point for a sequential read, it means the page right
next will be accessed without the right instructions. The NAND chip will
be confused and will not output correct data. In order to avoid such
situation from happening anymore, we can however handle this case with a
bit of additional logic, to postpone the initialization of the read
sequence by one page.

The ONFI specification states that devices do not need to support
sequential reads across LUN boundaries. In order to prevent such event
from happening and possibly failing, let's introduce the concept of
"pause" in the sequential read to handle these cases. The first/last
pages remain the same but any time we cross a LUN boundary we will end
and restart (if relevant) the sequential read operation.

If both ftl.ko and gluebi.ko are loaded, the notifier of ftl
triggers NULL pointer dereference when trying to access
‘gluebi->desc’ in gluebi_read().

gluebi->desc - NULL
Detailed reproduction information available at the Link [1],
In the normal case, obtain gluebi->desc in the gluebi_get_device(),
and access gluebi->desc in the gluebi_read(). However,
gluebi_get_device() is not executed in advance in the
ftl_add_mtd() process, which leads to NULL pointer dereference.
The solution for the gluebi module is to run jffs2 on the UBI
volume without considering working with ftl or mtdblock [2].
Therefore, this problem can be avoided by preventing gluebi from
creating the mtdblock device after creating mtd partition of the
type MTD_UBIVOLUME.

Tetsuo Handa pointed out that in the (now reverted)
lockdep commit I initialized the data too late. The
same is true for the cancellation data, it must be
initialized before the cmpxchg(), otherwise it may
be done twice and possibly even overwriting data in
there already when there's a race. Fix that, which
also requires destroying the mutex in case we lost
the race.

There isn't really much left in xfs_rtallocate_extent now, fold it into

There are currently multiple levels of fall back if an RT allocation
can not be satisfied:
1) xfs_rtallocate_extent extends the minlen and reduces the maxlen due
to the extent size hint. If that can't be done, it return -ENOSPC
and let's xfs_bmap_rtalloc retry, which then not only drops the
extent size hint based alignment, but also the minlen adjustment
2) if xfs_rtallocate_extent gets -ENOSPC from the underlying functions,
it only drops the extent size hint based alignment and retries
3) if that still does not succeed, xfs_rtallocate_extent drops the
extent size hint (which is a complex no-op at this point) and the
minlen using the same code as (1) above
4) if that still doesn't success and the caller wanted an allocation
near a blkno, drop that blkno hint.
The handling in 1 is rather inefficient as we could just drop the
alignment and continue, and 2/3 interact in really weird ways due to
the duplicate policy.
Move aligning the min and maxlen out of xfs_rtallocate_extent and into
a helper called directly by xfs_bmap_rtalloc. This allows just
continuing with the allocation if we have to drop the alignment instead
of going through the retry loop and also dropping the perfectly usable
minlen adjustment that didn't cause the problem, and then just use
a single retry that drops both the minlen and alignment requirement
when we really are out of space, thus consolidating cases (2) and (3)
above.

xfs_bmap_rtalloc is a bit of a mess in terms of calculating the locally
need variables. Reorder them a bit so that related code is located
next to each other - the raminlen calculation moves up next to where
the maximum len is calculated, and all the prod calculation is move
into a single place and rearranged so that the real prod calculation
only happens when it actually is needed.

Clean up the logical in xfs_bmap_rtalloc that tries to find a rtextent
to start the search from by using a separate variable for the hint, not
calling xfs_bmap_adjacent when we want to ignore the locality and avoid
an extra roundtrip converting between block numbers and RT extent
numbers.
As a side-effect this doesn't pointlessly call xfs_rtpick_extent and
increment the start rtextent hint if we are going to ignore the result
anyway.
