Pull yet more SPDX updates from Greg KH:
"Another round of SPDX header file fixes for 5.2-rc4
These are all more "GPL-2.0-or-later" or "GPL-2.0-only" tags being
added, based on the text in the files. We are slowly chipping away at
the 700+ different ways people tried to write the license text. All of
these were reviewed on the spdx mailing list by a number of different
people.
We now have over 60% of the kernel files covered with SPDX tags:
$ ./scripts/spdxcheck.py -v 2>&1 | grep Files
Files checked: 64533

Daniel Borkmann says:
====================
pull-request: bpf 2019-06-07
The following pull-request contains BPF updates for your *net* tree.
The main changes are:
1) Fix several bugs in riscv64 JIT code emission which forgot to clear high
32-bits for alu32 ops, from Björn and Luke with selftests covering all
relevant BPF alu ops from Björn and Jiong.
2) Two fixes for UDP BPF reuseport that avoid calling the program in case of
__udp6_lib_err and UDP GRO which broke reuseport_select_sock() assumption
that skb->data is pointing to transport header, from Martin.
3) Two fixes for BPF sockmap: a use-after-free from sleep in psock's backlog
workqueue, and a missing restore of sk_write_space when psock gets dropped,
from Jakub and John.
4) Fix unconnected UDP sendmsg hook API which is insufficient as-is since it
breaks standard applications like DNS if reverse NAT is not performed upon
receive, from Daniel.
5) Fix an out-of-bounds read in __bpf_skc_lookup which in case of AF_INET6
fails to verify that the length of the tuple is long enough, from Lorenz.
6) Fix libbpf's libbpf__probe_raw_btf to return an fd instead of 0/1 (for
{un,}successful probe) as that is expected to be propagated as an fd to
load_sk_storage_btf() and thus closing the wrong descriptor otherwise,
from Michal.
7) Fix bpftool's JSON output for the case when a lookup fails, from Krzesimir.
8) Minor misc fixes in docs, samples and selftests, from various others.

vm test build fails when test is built by itself using

The test is an adaption of the same test for x86. Note that there
are some differences in the way how s390x deals with the kvm_valid_regs
in struct kvm_run, so some of the tests had to be removed. Also this
test is not using the ucall() interface on s390x yet (which would need
some work to be usable on s390x), so it simply drops out of the VM with
a diag 0x501 breakpoint instead.

The struct kvm_vcpu_events code is only available on certain architectures
(arm, arm64 and x86). To be able to compile kvm_util.c also for other
architectures, we have to fence the code with __KVM_HAVE_VCPU_EVENTS.

sysctl setting bc_forwarding for $rp2 is needed when ping_test_from h2,
otherwise the bc packets from $rp2 won't be forwarded. This patch is to
add this setting for $rp2.
Also, as ping_test_from does grep "$from" only, which could match some
unexpected output, some test case doesn't really work, like:
# ping_test_from $h2 198.51.200.255 198.51.200.2
PING 198.51.200.255 from 198.51.100.2 veth3: 56(84) bytes of data.
64 bytes from 198.51.100.1: icmp_seq=1 ttl=64 time=0.336 ms
When doing grep $form (198.51.200.2), the output could still match.
So change to grep "bytes from $from" instead.

If the entry is deleted from the IDR between the call to
radix_tree_iter_find() and rcu_dereference_raw(), idr_get_next()
will return NULL, which will end the iteration prematurely. We should
instead continue to the next entry in the IDR. This only happens if the
iteration is protected by the RCU lock. Most IDR users use a spinlock
or semaphore to exclude simultaneous modifications. It was noticed once
the PID allocator was converted to use the IDR, as it uses the RCU lock,
but there may be other users elsewhere in the kernel.
We can't use the normal pattern of calling radix_tree_deref_retry()
(which catches both a retry entry in a leaf node and a node entry in
the root) as the IDR supports storing entries which are unaligned,
which will trigger an infinite loop if they are encountered. Instead,
we have to explicitly check whether the entry is a retry entry.

pull-request: bpf-next 2019-05-31
The following pull-request contains BPF updates for your *net-next* tree.
Lots of exciting new features in the first PR of this developement cycle!
The main changes are:
1) misc verifier improvements, from Alexei.
2) bpftool can now convert btf to valid C, from Andrii.
3) verifier can insert explicit ZEXT insn when requested by 32-bit JITs.
This feature greatly improves BPF speed on 32-bit architectures. From Jiong.
4) cgroups will now auto-detach bpf programs. This fixes issue of thousands
bpf programs got stuck in dying cgroups. From Roman.
5) new bpf_send_signal() helper, from Yonghong.
6) cgroup inet skb programs can signal CN to the stack, from Lawrence.
7) miscellaneous cleanups, from many developers.

xdping allows us to get latency estimates from XDP. Output looks
like this:

The xdping program loads the associated xdping_kern.o BPF program
and attaches it to the specified interface. If run in client
mode (the default), it will add a map entry keyed by the
target IP address; this map will store RTT measurements, current
sequence number etc. Finally in client mode the ping command
is executed, and the xdping BPF program will use the last ICMP
reply, reformulate it as an ICMP request with the next sequence
number and XDP_TX it. After the reply to that request is received
we can measure RTT and repeat until the desired number of
measurements is made. This is why the sequence numbers in the
normal ping are 1, 2, 3 and 8. We XDP_TX a modified version
of ICMP reply 4 and keep doing this until we get the 4 replies
we need; hence the networking stack only sees reply 8, where
we have XDP_PASSed it upstream since we are done.
In server mode (-s), xdping simply takes ICMP requests and replies
to them in XDP rather than passing the request up to the networking
stack. No map entry is required.
xdping can be run in native XDP mode (the default, or specified
via -N) or in skb mode (-S).
A test program test_xdping.sh exercises some of these options.
Note that native XDP does not seem to XDP_TX for veths, hence -N
is not tested. Looking at the code, it looks like XDP_TX is
supported so I'm not sure if that's expected. Running xdping in
native mode for ixgbe as both client and server works fine.
Changes since v4
- close fds on cleanup (Song Liu)
Changes since v3
- fixed seq to be __be16 (Song Liu)
- fixed fd checks in xdping.c (Song Liu)
Changes since v2
- updated commit message to explain why seq number of last
ICMP reply is 8 not 4 (Song Liu)
- updated types of seq number, raddr and eliminated csum variable
in xdpclient/xdpserver functions as it was not needed (Song Liu)
- added XDPING_DEFAULT_COUNT definition and usage specification of
default/max counts (Song Liu)
Changes since v1
- moved from RFC to PATCH
- removed unused variable in ipv4_csum() (Song Liu)
- refactored ICMP checks into icmp_check() function called by client
and server programs and reworked client and server programs due
to lack of shared code (Song Liu)
- added checks to ensure that SKB and native mode are not requested
together (Song Liu)

The phylink conflict was between a bug fix by Russell King
to make sure we have a consistent PHY interface mode, and
a change in net-next to pull some code in phylink_resolve()
into the helper functions phylink_mac_link_{up,down}()
On the dp83867 side it's mostly overlapping changes, with
the 'net' side removing a condition that was supposed to
trigger for RGMII but because of how it was coded never
actually could trigger.

Pull yet more SPDX updates from Greg KH:
"Here is another set of reviewed patches that adds SPDX tags to
different kernel files, based on a set of rules that are being used to
parse the comments to try to determine that the license of the file is
"GPL-2.0-or-later" or "GPL-2.0-only". Only the "obvious" versions of
these matches are included here, a number of "non-obvious" variants of
text have been found but those have been postponed for later review
and analysis.
There is also a patch in here to add the proper SPDX header to a bunch
of Kbuild files that we have missed in the past due to new files being
added and forgetting that Kbuild uses two different file names for
Makefiles. This issue was reported by the Kbuild maintainer.
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"
