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.

In the pmtu_vti6_link_change_mtu test, both local and remote addresses
for the vti6 tunnel are assigned to the same address given to the dummy
interface that we use as encapsulating device with a known MTU.
This works as long as the dummy interface is actually selected, via
rt6_lookup(), as encapsulating device. But if the remote address of the
tunnel is a local address too, the loopback interface could also be
selected, and there's nothing wrong with it.
This is what some older -stable kernels do (3.18.z, at least), and
nothing prevents us from subtly changing FIB implementation to revert
back to that behaviour in the future.
Define an IPv6 prefix instead, and use two separate addresses as local
and remote for vti6, so that the encapsulating device can't be a
loopback interface.

I was really surprised that the IPv6 mtu exception followed by redirect
test was passing as nothing about the code suggests it should. The problem
is actually with the logic in the test script.
Fix the test cases as follows:
1. add debug function to dump the initial and redirect gateway addresses
for ipv6. This is shown only in verbose mode. It helps verify the
output of 'route get'.
2. fix the check_exception logic for the reset case to make sure that
for IPv4 neither mtu nor redirect appears in the 'route get' output.
For IPv6, make sure mtu is not present and the gateway is the initial
R1 lladdr.
3. fix the reset logic by using a function to delete the routes added by
initial_route_*. This format works better for the nexthop version of
the tests.
While improving the test cases, go ahead and ensure that forwarding is
disabled since IPv6 redirect requires it.
Also, runs with kernel debugging enabled sometimes show a failure with
one of the ipv4 tests, so spread the pings over longer time interval.
The end result is that 2 tests now show failures:
TEST: IPv6: mtu exception plus redirect [FAIL]
and the VRF version.
This is a bug in the IPv6 logic that will need to be fixed
separately. Redirect followed by MTU works because __ip6_rt_update_pmtu
hits the 'if (!rt6_cache_allowed_for_pmtu(rt6))' path and updates the
mtu on the exception rt6_info.
MTU followed by redirect does not have this logic. rt6_do_redirect
creates a new exception and then rt6_insert_exception removes the old
one which has the MTU exception.

The SO_TXTIME API enables packet tranmission with delayed delivery.
This is currently supported by the ETF and FQ packet schedulers.
Evaluate the interface with both schedulers. Install the scheduler
and send a variety of packets streams: without delay, with one
delayed packet, with multiple ordered delays and with reordering.
Verify that packets are released by the scheduler in expected order.
The ETF qdisc requires a timestamp in the future on every packet. It
needs a delay on the qdisc else the packet is dropped on dequeue for
having a delivery time in the past. The test value is experimentally
derived. ETF requires clock_id CLOCK_TAI. It checks this base and
drops for non-conformance.
The FQ qdisc expects clock_id CLOCK_MONOTONIC, the base used by TCP
as of commit fb420d5d91 ("tcp/fq: move back to CLOCK_MONOTONIC").
Within a flow there is an expecation of ordered delivery, as shown by
delivery times of test 4. The FQ qdisc does not require all packets to
have timestamps and does not drop for non-conformance.
The large (msec) delays are chosen to avoid flakiness.
Output:
SO_TXTIME ipv6 clock monotonic
payload:a delay:28 expected:0 (us)
SO_TXTIME ipv4 clock monotonic
payload:a delay:38 expected:0 (us)
SO_TXTIME ipv6 clock monotonic

The point of the pause-on-fail argument is to leave the setup as is after
a test fails to allow a user to debug why it failed. Move the cleanup
after posting the result to the user to make it so.
Random names for the namespaces are not user friendly when trying to
debug a failure. Make them simpler and more direct for the tests. Run
cleanup at the beginning to ensure they are cleaned up if they already
exist.
Remove cleanup_done. There is no harm in doing cleanup twice; just
ignore any errors related to not existing - which is already done.

pmtu.sh script runs a number of tests and dumps a summary of pass/fail.
If a test fails, it is near impossible to debug why. For example:
TEST: ipv6: PMTU exceptions [FAIL]
There are a lot of commands run behind the scenes for this test. Which
one is failing?
Add a VERBOSE option to show commands that are run and any output from
those commands. Add a PAUSE_ON_FAIL option to halt the script if a test
fails allowing users to poke around with the setup in the failed state.

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

Just like commit e2ba732a16 ("selftests: fib_tests: sleep after

There are two sets of carrier tests. The first slept after the carrier
was set to off, and when the second set ran, it was likely that the
linkwatch would be able to run again without much delay, reducing the
likelihood of a race. However, if you run 'fib_tests.sh -t carrier' on a
loop, you will quickly notice the failures.
Sleeping on the second set of tests make the failures go away.

The global variable RET needs to be initialized before each call to

calls log_tests for every individual test. Thus a failure in one of the

The untagged egress test sets up mirroring to {,ip6}gretap such that the
underlay goes through a bridge. Then VLAN flags are manipulated to test
that the traffic leaves the bridge 802.1q-tagged or not, as appropriate.
However, when a neighbor expires at the time that the bridge VLAN is
configured as PVID and egress untagged, the following discovery process
can't finish, because the IP address on H3 is still at the VLAN-tagged
netdevice. This manifests by occasional failures where only several of
the 10 required packets get through.
Therefore, when reconfiguring the VLAN flags, move the IP address to the
appropriate device in the H3 VRF.
In addition to that, take this opportunity to embed an ASCII art diagram
to make the topology move obvious.

When running in an environment with poor performance (such as a

to arrive and bump the observed counters.

When running in a simulator, the TTL change takes a while to settle and
during this time the performance of the packet processing is lowered.
The resulting instability leads to ping sending more packets as it

The current ping intervals are too short for running mirroring tests in

It's GNU Make and linker specific.
The default Makefile rule looks like:
$(CC) $(CFLAGS) $(LDFLAGS) $@ $^ $(LDLIBS)
When linking is done by gcc itself, no issue, but when it needs to be passed
to proper ld, only LDLIBS follows and then ld cannot know what libs to link
with.
More detail:
https://www.gnu.org/software/make/manual/html_node/Implicit-Variables.html
LDFLAGS
Extra flags to give to compilers when they are supposed to invoke the linker,
‘ld’, such as -L. Libraries (-lfoo) should be added to the LDLIBS variable
instead.
LDLIBS
Library flags or names given to compilers when they are supposed to invoke the
linker, ‘ld’. LOADLIBES is a deprecated (but still supported) alternative to
LDLIBS. Non-library linker flags, such as -L, should go in the LDFLAGS
variable.

This patch adds several changes to the ip_defrag selftest, to cover
new IPv6 defrag behavior:
- min IPv6 frag size is now 8 instead of 1280
- new test cases to cover IPv6 defragmentation in nf_conntrack_reasm.c
- new "permissive" mode in negative (overlap) tests: netfilter
sometimes drops invalid packets without passing them to IPv6
underneath, and thus defragmentation sometimes succeeds when
it is expected to fail; so the permissive mode does not fail the
test if the correct reassembled datagram is received instead of a
timeout.

ARP suppression allows the Linux bridge to answer ARP requests on behalf
of remote hosts. It reduces the amount of packets a VTEP needs to flood.
This test verifies that ARP suppression on / off works when a neighbour
exists and when it does not exist. It does so by sending an ARP request
from a host connected to one VTEP and checking whether it was received
by a second VTEP.

In asymmetric routing the ingress VTEP routes the packet into the
correct VXLAN tunnel, whereas the egress VTEP only bridges the packet to
the correct host. Therefore, packets in different directions use
different VNIs - the target VNI.
The test uses a simple topology with two VTEPs and two VNIs and verifies
that ping passes between hosts (local / remote) in the same VLAN (VNI)
and in different VLANs belonging to the same tenant (VRF).
While the test does not check VM mobility, it does configure an anycast
gateway using a macvlan device on both VTEPs.

With very small change to test script we can trigger softlockup due to
bogus assignment of 'p' (policy to be examined) on restart.
Previously the two to-be-merged nodes had same address/prefixlength pair,
so no erase/reinsert was necessary, we only had to append the list from
node a to b.
If prefix lengths are different, the node has to be deleted and re-inserted
into the tree, with the updated prefix length. This was broken; due to
bogus update to 'p' this loops forever.
Add a 'restart' label and use that instead.
While at it, don't perform the unneeded reinserts of the policies that
are already sorted into the 'new' node.
A previous patch in this series made xfrm_policy_inexact_list_reinsert()
use the relative position indicator to sort policies according to age in
case priorities are identical.

The existing script lacks a policy pattern that triggers 'tree node
merges' in the kernel.
Consider adding policy affecting following subnet:
pol1: dst 10.0.0.0/22
pol2: dst 10.0.0.0/23 # adds to existing 10.0.0.0/22 node
-> no problems here. But now, lets consider reverse order:
pol1: dst 10.0.0.0/24
pol2: dst 10.0.0.0/23 # CANNOT add to existing node
When second policy gets added, the kernel must check that the new node
("10.0.0.0/23") doesn't overlap with any existing subnet.
Example:
dst 10.0.0.0/24
dst 10.0.0.1/24
dst 10.0.0.0/23
When the third policy gets added, the kernel must replace the nodes for
the 10.0.0.0/24 and 10.0.0.1/24 policies with a single one and must merge
all the subtrees/lists stored in those nodes into the new node.
The existing test cases only have overlaps with a single node, so no
merging takes place (we can always remove the 'old' node and replace
it with the new subnet prefix).
Add a few 'block policies' in a pattern that triggers this, with a priority
that will make kernel prefer the 'esp' rules.
Make sure the 'tunnel ping' tests still pass after they have been added.

When running the test on the Spectrum ASIC the generated packets are
counted on the ingress filter and injected back to the pipeline because
of the 'pass' action. The router block then drops the packets due to
checksum error, as the test generates packets with zero checksum.
When running the test on an emulator that is not as strict about
checksum errors the test fails since packets are counted twice. Once by
the emulated ASIC on its ingress filter and again by the kernel as the
emulator does not perform checksum validation and allows the packets to
be trapped by a matching host route.
Fix this by changing the action to 'drop', which will prevent the packet
from continuing further in the pipeline to the router block.
For veth pairs this change is essentially a NOP given packets are only
processed once (by the kernel).

This test opens two packet sockets, one to send and one to read.
The sender has a tx ring of one slot. It sends two packets with
different payload, then reads both and verifies their payload.
Before the above commit, both receive calls return the same data as
the send calls use the same buffer. From the commit, the clone

In order to run a certain command inside another network namespace, it's
possible to use "ip netns exec ns command". However then one can't use
functions defined in lib.sh or a test suite.
One option is to do "ip netns exec ns bash -c command", provided that
all functions that one wishes to use (and their dependencies) are
published using "export -f". That may not be practical.
Therefore, introduce a helper in_ns(), which wraps a given command in a
boilerplate of "ip netns exec" and "source lib.sh", thus making all
library functions available. (Custom functions that a script wishes to
run within a namespace still need to be exported.)

on IPv4 and IPv6 transport, that check that PMTU exceptions are created
with the right value when exceeding the MTU on a link of the path.

Use a router between endpoints, implemented via namespaces, set a low MTU
between router and destination endpoint, exceed it and check PMTU value in
route exceptions.
v2:
- Introduce IPv4 tests right away, if iproute2 doesn't support the 'df'
link option they will be skipped (David Ahern)

Extends the existing udp programs to allow checking for proper
GRO aggregation/GSO size, and run the tests via a shell script, using
a veth pair with XDP program attached to trigger the GRO code path.
rfc v3 -> v1:
- use ip route to attach the xdp helper to the veth
rfc v2 -> rfc v3:
- add missing test program options documentation
- fix sporatic test failures (receiver faster than sender)

And fix a couple of buglets (port option processing,
clean termination on SIGINT). This is preparatory work
for GRO tests.

The intent of ip6_route_check_nh_onlink is to make sure the gateway
given for an onlink route is not actually on a connected route for
a different interface (e.g., 2001:db8:1::/64 is on dev eth1 and then
an onlink route has a via 2001:db8:1::1 dev eth2). If the gateway
lookup hits the default route then it most likely will be a different
interface than the onlink route which is ok.
Update ip6_route_check_nh_onlink to disregard the device mismatch
if the gateway lookup hits the default route. Turns out the existing
onlink tests are passing because there is no default route or it is
an unreachable default, so update the onlink tests to have a default
route other than unreachable.

net/sched/cls_api.c has overlapping changes to a call to
nlmsg_parse(), one (from 'net') added rtm_tca_policy instead of NULL
to the 5th argument, and another (from 'net-next') added cb->extack
instead of NULL to the 6th argument.
net/ipv4/ipmr_base.c is a case of a bug fix in 'net' being done to
code which moved (to mr_table_dump)) in 'net-next'. Thanks to David
Ahern for the heads up.

As number of tests is growing, it's quite convenient to allow
single tests to be run.
Display usage when the script is run with any invalid argument,
keep existing semantics when no arguments are passed so that
automated runs won't break.
Instead of just looping on the list of requested tests, if any,
check first that they exist, and go through them in a nested
loop to keep the existing way to display test descriptions.

====================
pull-request: bpf 2018-10-14
The following pull-request contains BPF updates for your *net* tree.
The main changes are:
1) Fix xsk map update and delete operation to not call synchronize_net()
but to piggy back on SOCK_RCU_FREE for sockets instead as we are not
allowed to sleep under RCU, from Björn.
2) Do not change RLIMIT_MEMLOCK in reuseport_bpf selftest if the process
already has unlimited RLIMIT_MEMLOCK, from Eric.
