Disassociate the exec_key from a VMA if the VMA permission is not
PROT_EXEC anymore. Otherwise the exec_only key continues to be
associated with the vma, causing unexpected behavior.
The problem was reported on x86 by Shakeel Butt, which is also
applicable on powerpc.

Pull locking updates from Ingo Molnar:
- Lots of tidying up changes all across the map for Linux's formal
memory/locking-model tooling, by Alan Stern, Akira Yokosawa, Andrea
Parri, Paul E. McKenney and SeongJae Park.
Notable changes beyond an overall update in the tooling itself is the
tidying up of spin_is_locked() semantics, which spills over into the
kernel proper as well.
- qspinlock improvements: the locking algorithm now guarantees forward
progress whereas the previous implementation in mainline could starve
threads indefinitely in cmpxchg() loops. Also other related cleanups
to the qspinlock code (Will Deacon)
- misc smaller improvements, cleanups and fixes all across the locking
subsystem

Pull siginfo updates from Eric Biederman:
"This set of changes close the known issues with setting si_code to an
invalid value, and with not fully initializing struct siginfo. There
remains work to do on nds32, arc, unicore32, powerpc, arm, arm64, ia64
and x86 to get the code that generates siginfo into a simpler and more
maintainable state. Most of that work involves refactoring the signal
handling code and thus careful code review.
Also not included is the work to shrink the in kernel version of
struct siginfo. That depends on getting the number of places that
directly manipulate struct siginfo under control, as it requires the
introduction of struct kernel_siginfo for the in kernel things.
Overall this set of changes looks like it is making good progress, and
with a little luck I will be wrapping up the siginfo work next
development cycle"

Pull userns updates from Eric Biederman:
"This is the last couple of vfs bits to enable root in a user namespace
to mount and manipulate a filesystem with backing store (AKA not a
virtual filesystem like proc, but a filesystem where the unprivileged
user controls the content). The target filesystem for this work is
fuse, and Miklos should be sending you the pull request for the fuse
bits this merge window.
The two key patches are "evm: Don't update hmacs in user ns mounts"
and "vfs: Don't allow changing the link count of an inode with an
invalid uid or gid". Those close small gaps in the vfs that would be a
problem if an unprivileged fuse filesystem is mounted.
The rest of the changes are things that are now safe to allow a root
user in a user namespace to do with a filesystem they have mounted.
The most interesting development is that remount is now safe"

====================
Intel Wired LAN Driver Updates 2018-06-04
This series contains a smorgasbord of updates to documentation, e1000e,
igb, ixgbe, ixgbevf and i40e.
Benjamin Poirier fixes a potential kernel crash due to NULL pointer
dereference in e1000e.
Jeff updates the kernel documentation for e100 and e1000 to correct
default values and URLs which were incorrect in the documentation. Also
took the time to update these to the new reStructured text format for
kernel documentation.
Joanna Yurdal fixes a missing PTP transmit timestamp by ensuring that
TSICR gets cleared when ICR is cleared.
Sergey updates igb to reset all the transmit queues at one time so that
we only have to wait once for all the queues to be reset.
Alex fixes ixgbevf so that malicious driver detection (MDD) can co-exist
with XDP.
Emil and Tony extend the RTNL lock to ensure we get the most up-to-date
values for the bits and avoid a possible race condition when going down.
YueHaibing from Huawei introduces a helper function in ixgbe for
operation reads to simplify the code a bit more.
Daniel Borkmann adds support for XDP meta data when using build SKB
for i40e.
Shannon Nelson provides twp fixes for the IPSec code in ixgbe, first is
to make sure we do not try to offload the decryption of any incoming
packet that is destined for the management engine. The other fix is to
resolve a cast problem introduced by a sparse cleanup patch.

Pull btrfs updates from David Sterba:
"User visible features:
- added support for the ioctl FS_IOC_FSGETXATTR, per-inode flags,
successor of GET/SETFLAGS; now supports only existing flags:
append, immutable, noatime, nodump, sync
- 3 new unprivileged ioctls to allow users to enumerate subvolumes
- dedupe syscall implementation does not restrict the range to 16MiB,
though it still splits the whole range to 16MiB chunks
- on user demand, rmdir() is able to delete an empty subvolume,
export the capability in sysfs
- fix inode number types in tracepoints, other cleanups
- send: improved speed when dealing with a large removed directory,
measurements show decrease from 2000 minutes to 2 minutes on a
directory with 2 million entries
- pre-commit check of superblock to detect a mysterious in-memory
corruption
- log message updates
Other changes:
- orphan inode cleanup improved, does no keep long-standing
reservations that could lead up to early ENOSPC in some cases
- slight improvement of handling snapshotted NOCOW files by avoiding
some unnecessary tree searches
- avoid OOM when dealing with many unmergeable small extents at flush
time
- speedup conversion of free space tree representations from/to
bitmap/tree
- code refactoring, deletion, cleanups:
+ delayed refs
+ delayed iput
+ redundant argument removals
+ memory barrier cleanups
+ remove a redundant mutex supposedly excluding several ioctls to
run in parallel
- new tracepoints for blockgroup manipulation
- more sanity checks of compressed headers"

The function __builtin_expect returns long type (see the gcc
documentation), and so do macros likely and unlikely. Unfortunatelly, when
CONFIG_PROFILE_ANNOTATED_BRANCHES is selected, the macros likely and
unlikely expand to __branch_check__ and __branch_check__ truncates the
long type to int. This unintended truncation may cause bugs in various
kernel code (we found a bug in dm-writecache because of it), so it's
better to fix __branch_check__ to return long.

It is not safe to do so because such sockets are already in the
hash tables and changing these options can result in invalidating
the tb->fastreuse(port) caching.
This can have later far reaching consequences wrt. bind conflict checks
which rely on these caches (for optimization purposes).
Not to mention that you can currently end up with two identical
non-reuseport listening sockets bound to the same local ip:port
by clearing reuseport on them after they've already both been bound.
There is unfortunately no EISBOUND error or anything similar,
and EISCONN seems to be misleading for a bound-but-not-connected
socket, so use EUCLEAN 'Structure needs cleaning' which AFAICT
is the closest you can get to meaning 'socket in bad state'.
(although perhaps EINVAL wouldn't be a bad choice either?)
This does unfortunately run the risk of breaking buggy
userspace programs...

This changes the /proc/sys/net/ipv4/tcp_tw_reuse from a boolean
to an integer.
It now takes the values 0, 1 and 2, where 0 and 1 behave as before,
while 2 enables timewait socket reuse only for sockets that we can
prove are loopback connections:
ie. bound to 'lo' interface or where one of source or destination
IPs is 127.0.0.0/8, ::ffff:127.0.0.0/104 or ::1.
This enables quicker reuse of ephemeral ports for loopback connections
- where tcp_tw_reuse is 100% safe from a protocol perspective
(this assumes no artificially induced packet loss on 'lo').
This also makes estblishing many loopback connections *much* faster
(allocating ports out of the first half of the ephemeral port range
is significantly faster, then allocating from the second half)
Without this change in a 32K ephemeral port space my sample program
(it just establishes and closes [::1]:ephemeral -> [::1]:server_port
connections in a tight loop) fails after 32765 connections in 24 seconds.
With it enabled 50000 connections only take 4.7 seconds.
This is particularly problematic for IPv6 where we only have one local
address and cannot play tricks with varying source IP from 127.0.0.0/8
pool.
