Pull SPDX update from Greg KH:
"Here is a series of patches that add SPDX tags to different kernel
files, based on two different things:- SPDX entries are added to a bunch of files that we missed a year
ago that do not have any license information at all.These were either missed because the tool saw the MODULE_LICENSE()
tag, or some EXPORT_SYMBOL tags, and got confused and thought the
file had a real license, or the files have been added since the
last big sweep, or they were Makefile/Kconfig files, which we
didn't touch last time.- Add GPL-2.0-only or GPL-2.0-or-later tags to files where our scan
tools can determine the license text in the file itself. Where this
happens, the license text is removed, in order to cut down on the
700+ different ways we have in the kernel today, in a quest to get
rid of all of these.These patches have been out for review on the linux-spdx@vger mailing
list, and while they were created by automatic tools, they were
hand-verified by a bunch of different people, all whom names are on
the patches are reviewers.The reason for these "large" patches is if we were to continue to
progress at the current rate of change in the kernel, adding license
tags to individual files in different subsystems, we would be finished
in about 10 years at the earliest.There will be more series of these types of patches coming over the
next few weeks as the tools and reviewers crunch through the more
"odd" variants of how to say "GPLv2" that developers have come up with
over the years, combined with other fun oddities (GPL + a BSD
disclaimer?) that are being unearthed, with the goal for the whole
kernel to be cleaned up.These diffstats are not small, 3840 files are touched, over 10k lines
removed in just 24 patches"* tag 'spdx-5.2-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core: (24 commits)

Currently, the Kbuild core manipulates header search paths in a crazy
way [1].To fix this mess, I want all Makefiles to add explicit $(srctree)/ to
the search paths in the srctree. Some Makefiles are already written in
that way, but not all. The goal of this work is to make the notation
consistent, and finally get rid of the gross hacks.Having whitespaces after -I does not matter since commit 48f6e3cf5bc6

Pull misc AFS fixes from David Howells:
"This fixes a set of miscellaneous issues in the afs filesystem,
including:- leak of keys on file close.
- broken error handling in xattr functions.
- missing locking when updating VL server list.
- volume location server DNS lookup whereby preloaded cells may not
ever get a lookup and regular DNS lookups to maintain server lists
consume power unnecessarily.- incorrect error propagation and handling in the fileserver
iteration code causes operations to sometimes apparently succeed.- interruption of server record check/update side op during
fileserver iteration causes uninterruptible main operations to fail
unexpectedly.- callback promise expiry time miscalculation.
- over invalidation of the callback promise on directories.
- double locking on callback break waking up file locking waiters.
- double increment of the vnode callback break counter.
Note that it makes some changes outside of the afs code, including:
- an extra parameter to dns_query() to allow the dns_resolver key
just accessed to be immediately invalidated. AFS is caching the
results itself, so the key can be discarded.- an interruptible version of wait_var_event().
- an rxrpc function to allow the maximum lifespan to be set on a
call.- a way for an rxrpc call to be marked as non-interruptible"

When inserting route cache into the exception table, the key is
generated with both src_addr and dest_addr with src addr routing.
However, current logic always assumes the src_addr used to generate the
key is a /128 host address. This is not true in the following scenarios:
1. When the route is a gateway route or does not have next hop.
(rt6_is_gw_or_nonexthop() == false)
2. When calling ip6_rt_cache_alloc(), saddr is passed in as NULL.
This means, when looking for a route cache in the exception table, we
have to do the lookup twice: first time with the passed in /128 host
address, second time with the src_addr stored in fib6_info.This solves the pmtu discovery issue reported by Mikael Magnusson where
a route cache with a lower mtu info is created for a gateway route with
src addr. However, the lookup code is not able to find this route cache.Fixes: 2b760fcf5cfb ("ipv6: hook up exception table to store dst cache")

This resurrects commit 8742dc86d0c7a9628
("xfrm4: Fix uninitialized memory read in _decode_session4"),
which got lost during a merge conflict resolution between ipsec-next
and net-next tree.c53ac41e3720 ("xfrm: remove decode_session indirection from afinfo_policy")
in ipsec-next moved the (buggy) _decode_session4 from
net/ipv4/xfrm4_policy.c to net/xfrm/xfrm_policy.c.
In mean time, 8742dc86d0c7a was applied to ipsec.git and fixed the
problem in the "old" location.When the trees got merged, the moved, old function was kept.
This applies the "lost" commit again, to the new location.Fixes: a658a3f2ecbab ("Merge branch 'master' of git://git.kernel.org/pub/scm/linux/kernel/git/klassert/ipsec-next")

When tipc is loaded while many processes try to create a TIPC socket,
a crash occurs:

...This is due to race between sock_create and unfinished
register_pernet_device. tipc_sk_insert tries to do
"net_generic(net, tipc_net_id)".
but tipc_net_id is not initialized yet.So switch the order of the two to close the race.
This can be reproduced with multiple processes doing socket(AF_TIPC, ...)
and one process doing module removal.Fixes: a62fbccecd62 ("tipc: make subscriber server support net namespace")

At ipv6 route dismantle, fib6_drop_pcpu_from() is responsible
for finding all percpu routes and set their ->from pointer
to NULL, so that fib6_ref can reach its expected value (1).The problem right now is that other cpus can still catch the
route being deleted, since there is no rcu grace period
between the route deletion and call to fib6_drop_pcpu_from()This can leak the fib6 and associated resources, since no
notifier will take care of removing the last reference(s).I decided to add another boolean (fib6_destroying) instead
of reusing/renaming exception_bucket_flushed to ease stable backports,
and properly document the memory barriers used to implement this fix.This patch has been co-developped with Wei Wang.

Currently, hvsock does not implement any delayed or background close
logic. Whenever the hvsock socket is closed, a FIN is sent to the peer, and
the last reference to the socket is dropped, which leads to a call to
.destruct where the socket can hang indefinitely waiting for the peer to
close it's side. The can cause the user application to hang in the close()
call.This change implements proper STREAM(TCP) closing handshake mechanism by
sending the FIN to the peer and the waiting for the peer's FIN to arrive
for a given timeout. On timeout, it will try to terminate the connection
(i.e. a RST). This is in-line with other socket providers such as virtio.This change does not address the hang in the vmbus_hvsock_device_unregister
where it waits indefinitely for the host to rescind the channel. That
should be taken up as a separate fix.Signed-off-by: Sunil Muthuswamy

Allow kernel services using AF_RXRPC to indicate that a call should be
non-interruptible. This allows kafs to make things like lock-extension and
writeback data storage calls non-interruptible.If this is set, signals will be ignored for operations on that call where
possible - such as waiting to get a call channel on an rxrpc connection.It doesn't prevent UDP sendmsg from being interrupted, but that will be
handled by packet retransmission.rxrpc_kernel_recv_data() isn't affected by this since that never waits,
preferring instead to return -EAGAIN and leave the waiting to the caller.Userspace initiated calls can't be set to be uninterruptible at this time.

====================
pull-request: bpf 2019-05-16The following pull-request contains BPF updates for your *net* tree.
The main changes are:
1) Fix a use after free in __dev_map_entry_free(), from Eric.
2) Several sockmap related bug fixes: a splat in strparser if
it was never initialized, remove duplicate ingress msg list
purging which can race, fix msg->sg.size accounting upon
skb to msg conversion, and last but not least fix a timeout
bug in tcp_bpf_wait_data(), from John.3) Fix LRU map to avoid messing with eviction heuristics upon
syscall lookup, e.g. map walks from user space side will
then lead to eviction of just recently created entries on
updates as it would mark all map entries, from Daniel.4) Don't bail out when libbpf feature probing fails. Also
various smaller fixes to flow_dissector test, from Stanislav.5) Fix missing brackets for BTF_INT_OFFSET() in UAPI, from Gary.

Pull nfsd updates from Bruce Fields:
"This consists mostly of nfsd container work:Scott Mayhew revived an old api that communicates with a userspace
daemon to manage some on-disk state that's used to track clients
across server reboots. We've been using a usermode_helper upcall for
that, but it's tough to run those with the right namespaces, so a
daemon is much friendlier to container use cases.Trond fixed nfsd's handling of user credentials in user namespaces. He
also contributed patches that allow containers to support different
sets of NFS protocol versions.The only remaining container bug I'm aware of is that the NFS reply
cache is shared between all containers. If anyone's aware of other
gaps in our container support, let me know.The rest of this is miscellaneous bugfixes"
