feature, which allows ext4 directories to support over 2 billion
directory entries (assuming ~64 byte file names; in practice, users
will run into practical performance limits first.) This feature was
originally written by the Lustre team, and credit goes to Artem
Blagodarenko from Seagate for getting this feature upstream.
The second major major feature allows ext4 to support extended
attribute values up to 64k. This feature was also originally from
Lustre, and has been enhanced by Tahsin Erdogan from Google with a
deduplication feature so that if multiple files have the same xattr
value (for example, Windows ACL's stored by Samba), only one copy will
be stored on disk for encoding and caching efficiency.
We also have the usual set of bug fixes, cleanups, and optimizations.

As Hongjun/Nicolas summarized in their original patch:
"
When a device changes from one netns to another, it's first unregistered,
then the netns reference is updated and the dev is registered in the new
netns. Thus, when a slave moves to another netns, it is first
unregistered. This triggers a NETDEV_UNREGISTER event which is caught by
the bonding driver. The driver calls bond_release(), which calls
dev_set_mtu() and thus triggers NETDEV_CHANGEMTU (the device is still in
the old netns).
"
This is a very special case, because the device is being unregistered
no one should still care about the NETDEV_CHANGEMTU event triggered
at this point, we can avoid broadcasting this event on this path,
and avoid touching inetdev_event()/addrconf_notify() path.
It requires to export __dev_set_mtu() to bonding driver.

sock_graft() unilaterally sets up parent->sk based on the
assumption that the existing parent->sk is null. If this
condition is not true, then the existing parent->sk would
be leaked, so add a WARN_ON() to alert callers who may fall
in this category.

There are two problems with calling sock_create_kern() from
rds_tcp_accept_one()
1. it sets up a new_sock->sk that is wasteful, because this ->sk
is going to get replaced by inet_accept() in the subsequent ->accept()
2. The new_sock->sk is a leaked reference in sock_graft() which
expects to find a null parent->sk
Avoid these problems by calling sock_create_lite().

In architectures that use qspinlock, like x86, prefetch is loaded
indirectly via the asm/qspinlock.h include. On other architectures, like
OpenRISC, which may want to use asm-generic/qspinlock.h the built will
fail without the asm/prefetch.h include.
Fix this by including directly.

With some configs, objtool reports the following warning:
arch/x86/kernel/ftrace.o: warning: objtool: ftrace_modify_code_direct()+0x2d: sibling call from callable instruction with modified stack frame
The instruction it's complaining about isn't actually a sibling call.
It's just a normal jump to an address inside the function. Objtool
thought it was a sibling call because the instruction's jump_dest wasn't
initialized because the function was supposed to be ignored due to its
use of sync_core().
Objtool ended up validating the function instead of ignoring it because
it didn't properly recognize a sibling call to the function. So fix the
sibling call logic. Also add a warning to catch ignored functions being
validated so we'll get a more useful error message next time.

Pull iov_iter hardening from Al Viro:
"This is the iov_iter/uaccess/hardening pile.
For one thing, it trims the inline part of copy_to_user/copy_from_user
to the minimum that *does* need to be inlined - object size checks,
basically. For another, it sanitizes the checks for iov_iter
primitives. There are 4 groups of checks: access_ok(), might_fault(),
object size and KASAN.
- access_ok() had been verified by whoever had set the iov_iter up.
However, that has happened in a function far away, so proving that
there's no path to actual copying bypassing those checks is hard
and proving that iov_iter has not been buggered in the meanwhile is
also not pleasant. So we want those redone in actual
copyin/copyout.
- might_fault() is better off consolidated - we know whether it needs
to be checked as soon as we enter iov_iter primitive and observe
the iov_iter flavour. No need to wait until the copyin/copyout. The
call chains are short enough to make sure we won't miss anything -
in fact, it's more robust that way, since there are cases where we
do e.g. forced fault-in before getting to copyin/copyout. It's not
quite what we need to check (in particular, combination of
iovec-backed and set_fs(KERNEL_DS) is almost certainly a bug, not a
cause to skip checks), but that's for later series. For now let's
keep might_fault().
- KASAN checks belong in copyin/copyout - at the same level where
other iov_iter flavours would've hit them in memcpy().
- object size checks should apply to *all* iov_iter flavours, not
just iovec-backed ones.
There are two groups of primitives - one gets the kernel object
described as pointer + size (copy_to_iter(), etc.) while another gets
it as page + offset + size (copy_page_to_iter(), etc.)
For the first group the checks are best done where we actually have a
chance to find the object size. In other words, those belong in inline
wrappers in uio.h, before calling into iov_iter.c. Same kind as we
have for inlined part of copy_to_user().
For the second group there is no object to look at - offset in page is
just a number, it bears no type information. So we do them in the
common helper called by iov_iter.c primitives of that kind. All it
currently does is checking that we are not trying to access outside of
the compound page; eventually we might want to add some sanity checks
on the page involved.
So the things we need in copyin/copyout part of iov_iter.c do not
quite match anything in uaccess.h (we want no zeroing, we *do* want
access_ok() and KASAN and we want no might_fault() or object size
checks done on that level). OTOH, these needs are simple enough to
provide a couple of helpers (static in iov_iter.c) doing just what we
need..."

iov_iter: saner checks on copyin/copyout

execs, just limit all arg stack usage to at most 75% of _STK_LIM (6MB).

Pull Writeback error handling updates from Jeff Layton:
"This pile represents the bulk of the writeback error handling fixes
that I have for this cycle. Some of the earlier patches in this pile
may look trivial but they are prerequisites for later patches in the
series.
The aim of this set is to improve how we track and report writeback
errors to userland. Most applications that care about data integrity
will periodically call fsync/fdatasync/msync to ensure that their
writes have made it to the backing store.
For a very long time, we have tracked writeback errors using two flags
in the address_space: AS_EIO and AS_ENOSPC. Those flags are set when a
writeback error occurs (via mapping_set_error) and are cleared as a
side-effect of filemap_check_errors (as you noted yesterday). This
model really sucks for userland.
Only the first task to call fsync (or msync or fdatasync) will see the
error. Any subsequent task calling fsync on a file will get back 0
(unless another writeback error occurs in the interim). If I have
several tasks writing to a file and calling fsync to ensure that their
writes got stored, then I need to have them coordinate with one
another. That's difficult enough, but in a world of containerized
setups that coordination may even not be possible.
But wait...it gets worse!
The calls to filemap_check_errors can be buried pretty far down in the
call stack, and there are internal callers of filemap_write_and_wait
and the like that also end up clearing those errors. Many of those
callers ignore the error return from that function or return it to
userland at nonsensical times (e.g. truncate() or stat()). If I get
back -EIO on a truncate, there is no reason to think that it was
because some previous writeback failed, and a subsequent fsync() will
(incorrectly) return 0.
This pile aims to do three things:
1) ensure that when a writeback error occurs that that error will be
reported to userland on a subsequent fsync/fdatasync/msync call,
regardless of what internal callers are doing
2) report writeback errors on all file descriptions that were open at
the time that the error occurred. This is a user-visible change,
but I think most applications are written to assume this behavior
anyway. Those that aren't are unlikely to be hurt by it.
3) document what filesystems should do when there is a writeback
error. Today, there is very little consistency between them, and a
lot of cargo-cult copying. We need to make it very clear what
filesystems should do in this situation.
To achieve this, the set adds a new data type (errseq_t) and then
builds new writeback error tracking infrastructure around that. Once
all of that is in place, we change the filesystems to use the new
infrastructure for reporting wb errors to userland.
Note that this is just the initial foray into cleaning up this mess.
There is a lot of work remaining here:
1) convert the rest of the filesystems in a similar fashion. Once the
initial set is in, then I think most other fs' will be fairly
simple to convert. Hopefully most of those can in via individual
filesystem trees.
2) convert internal waiters on writeback to use errseq_t for
detecting errors instead of relying on the AS_* flags. I have some
draft patches for this for ext4, but they are not quite ready for
prime time yet.
This was a discussion topic this year at LSF/MM too. If you're
interested in the gory details, LWN has some good articles about this:

take_dentry_name_snapshot() takes a safe snapshot of dentry name;
if the name is a short one, it gets copied into caller-supplied
structure, otherwise an extra reference to external name is grabbed
(those are never modified). In either case the pointer to stable
string is stored into the same structure.
dentry must be held by the caller of take_dentry_name_snapshot(),
but may be freely dropped afterwards - the snapshot will stay
until destroyed by release_dentry_name_snapshot().
Intended use:
struct name_snapshot s;
take_dentry_name_snapshot(&s, dentry);

access s.name
...
release_dentry_name_snapshot(&s);

Thin archives migration by Nicholas Piggin.
THIN_ARCHIVES has been available for a while as an optional feature
only for PowerPC architecture, but we do not need two different
intermediate-artifact schemes.
Using thin archives instead of conventional incremental linking has
various advantages:
- save disk space for builds
- speed-up building a little
- fix some link issues (for example, allyesconfig on ARM) due to
more flexibility for the final linking
- work better with dead code elimination we are planning
As discussed before, this migration has been done unconditionally
so that any problems caused by this will show up with "git bisect".
With testing with 0-day and linux-next, some architectures actually
showed up problems, but they were trivial and all fixed now.

Merge tag 'kbuild-misc-v4.13' of git://git.kernel.org/pub/scm/linux/kernel/git/masahiroy/linux-kbuild
Pull misc Kbuild updates from Masahiro Yamada:
- Use more portable shebang for Perl scripts
- Remove trailing spaces from GCC version in kernel log
- Make initramfs generation deterministic
* tag 'kbuild-misc-v4.13' of git://git.kernel.org/pub/scm/linux/kernel/git/masahiroy/linux-kbuild:
kbuild: create deterministic initramfs directory listings
scripts/mkcompile_h: Remove trailing spaces from compiler version
scripts: Switch to more portable Perl shebang
This update consists of:
-- TAP13 framework and changes to some tests to convert to TAP13.
Converting kselftest output to standard format will help identify
run to run differences and pin point failures easily. TAP13 format
has been in use for several years and the output is human friendly.
Please find the specification:
https://testanything.org/tap-version-13-specification.html
Credit goes to Tim Bird for recommending TAP13 as a suitable format,
and to Grag KH for kick starting the work with help from Paul Elder
and Alice Ferrazzi
The first phase of the TAp13 conversion is included in this update.
Future updates will include updates to rest of the tests.
-- Masami Hiramatsu fixed ftrace to run on 4.9 stable kernels.
-- Kselftest documnetation has been converted to ReST format. Document
now has a new home under Documentation/dev-tools.
-- kselftest_harness.h is now available for general use as a result of
Mickaël Salaün's work.
-- Several fixes to skip and/or fail tests gracefully on older releases.
