When running without USERNS or PIDNS the seccomp test would hang since
it was waiting forever for the child to trigger the user notification
since it seems the glibc() abort handler makes a call to getpid(),
which would trap again. This changes the getpid filter to getppid, and
makes sure ASSERTs execute to stop from spawning the listener.

"I debated holding this back for the v5.2 merge window due to the size
of the "zero-key" changes, but affected users would benefit from
having the fixes sooner. It did not make sense to change the zero-key
semantic in isolation for the "secure-erase" command, but instead
include it for all security commands.
The short background on the need for these changes is that some NVDIMM
platforms enable security with a default zero-key rather than let the
OS specify the initial key. This makes the security enabling that
landed in v5.0 unusable for some users.

Sven Auhagen reported that a 2nd ping request will fail if 'fully-random'
mode is used.
Reason is that if no proto information is given, min/max are both 0,
so we set the icmp id to 0 instead of chosing a random value between
0 and 65535.
Update test case as well to catch this, without fix this yields:
[..]

When an icmp error such as pkttoobig is received, conntrack checks
if the "inner" header (header of packet that did not fit link mtu)
is matches an existing connection, and, if so, sets that packet as
being related to the conntrack entry it found.
It was recently reported that this "related" setting also works
if the inner header is from another, different connection (i.e.,
artificial/forged icmp error).
Add a test, followup patch will add additional "inner dst matches
outer dst in reverse direction" check before setting related state.

one is failing?
Add a VERBOSE option to show commands that are run and any output from

pull-request: bpf-next 2019-04-12
The following pull-request contains BPF updates for your *net-next* tree.
The main changes are:
1) Improve BPF verifier scalability for large programs through two
optimizations: i) remove verifier states that are not useful in pruning,
ii) stop walking parentage chain once first LIVE_READ is seen. Combined
gives approx 20x speedup. Increase limits for accepting large programs
under root, and add various stress tests, from Alexei.
2) Implement global data support in BPF. This enables static global variables
for .data, .rodata and .bss sections to be properly handled which allows
for more natural program development. This also opens up the possibility
to optimize program workflow by compiling ELFs only once and later only
rewriting section data before reload, from Daniel and with test cases and
libbpf refactoring from Joe.
3) Add config option to generate BTF type info for vmlinux as part of the
kernel build process. DWARF debug info is converted via pahole to BTF.
Latter relies on libbpf and makes use of BTF deduplication algorithm which
results in 100x savings compared to DWARF data. Resulting .BTF section is
typically about 2MB in size, from Andrii.
4) Add BPF verifier support for stack access with variable offset from
helpers and add various test cases along with it, from Andrey.
5) Extend bpf_skb_adjust_room() growth BPF helper to mark inner MAC header
so that L2 encapsulation can be used for tc tunnels, from Alan.
6) Add support for input __sk_buff context in BPF_PROG_TEST_RUN so that
users can define a subset of allowed __sk_buff fields that get fed into
the test program, from Stanislav.
7) Add bpf fs multi-dimensional array tests for BTF test suite and fix up
various UBSAN warnings in bpftool, from Yonghong.
8) Generate a pkg-config file for libbpf, from Luca.
9) Dump program's BTF id in bpftool, from Prashant.
10) libbpf fix to use smaller BPF log buffer size for AF_XDP's XDP
program, from Magnus.

ebtables -t broute allows to redirect packets in a way that
they get pushed up the stack, even if the interface is part
of a bridge.
In case of IP packets to non-local address, this means
those IP packets are routed instead of bridged-forwarded, just
as if the bridge would not have existed.
Expected test output is:
PASS: netns connectivity: ns1 and ns2 can reach each other
PASS: ns1/ns2 connectivity with active broute rule

A couple of tests are verifying a route has been removed. The helper
expects the prefix as the first part of the expected output. When
checking that a route has been deleted the prefix is empty leading
to an invalid ip command:
$ ip ro ls match
Command line is not complete. Try option "help"
Fix by moving the comparison of expected output and output to a new
function that is used by both check_route and check_route6. Use the
new helper for the 2 checks on route removal.
Also, remove the reset of 'set -x' in route_setup which overrides the

__rhashtable_insert_fast() is called with NULL key pointer, it never
actually checks for duplicates, which means that -EEXIST is never returned

Extend test_verifier with various test cases around the two kernel
extensions, that is, {rd,wr}only map support as well as direct map
value access. All passing, one skipped due to xskmap not present
on test machine:
# ./test_verifier

Pull networking fixes from David Miller:
1) Off by one and bounds checking fixes in NFC, from Dan Carpenter.
2) There have been many weird regressions in r8169 since we turned ASPM
support on, some are still not understood nor completely resolved.
Let's turn this back off for now. From Heiner Kallweit.
3) Signess fixes for ethtool speed value handling, from Michael
Zhivich.
4) Handle timestamps properly in macb driver, from Paul Thomas.
5) Two erspan fixes, it's the usual "skb ->data potentially reallocated
and we're holding a stale protocol header pointer". From Lorenzo
Bianconi.

Three new tests added:
1. Send get random cmd, read header in 1st read, read the rest in second
read - expect success
2. Send get random cmd, read only part of the response, send another
get random command, read the response - expect success
3. Send get random cmd followed by another get random cmd, without
reading the first response - expect the second cmd to fail with -EBUSY

Dan reported, that cleanup path in test_memcg_subtree_control()
triggers a static checker warning:
./tools/testing/selftests/cgroup/test_memcontrol.c:76 \
test_memcg_subtree_control()
error: uninitialized symbol 'child2'.
Fix this by initializing child2 and parent2 variables and
split the cleanup path into few stages.

After the first run, the test case 'test_create_read' will always
fail because the file is exist and file's attr is 'S_IMMUTABLE',
open with 'O_RDWR' will always return -EPERM.
