00d5622967 selftests: forwarding: mirror_vlan: Uninstall trap
Instead of installing a trap before tests run and uninstalling it after
they run, mirror_vlan.sh installs it twice due to a typo. Fix the typo.

75f0139fd6 selftests/net: add packet socket packet_snd test
Add regression tests for PF_PACKET transmission using packet_snd.

The TPACKET ring interface has tests for transmission and reception.
This is an initial stab at the same for the send call based interface.

Packets are sent over loopback, then read twice. The entire packet is
read from another packet socket and compared. The packet is also
verified to arrive at a UDP socket for protocol conformance.

The test sends a packet over loopback, testing the following options
(not the full cross-product):

- SOCK_DGRAM
- SOCK_RAW
- vlan tag
- qdisc bypass
- bind() and sendto()
- virtio_net_hdr
- csum offload (NOT actual csum feature, ignored on loopback)
- gso

Besides these basic functionality tests, the test runs from a set
of bounds checks, positive and negative. Running over loopback, which
has dev->min_header_len, it cannot generate variable length hhlen.

00f333e8d6 selftests/net: udpgso: test small gso_size boundary conditions
Verify that udpgso can generate segments smaller than device mtu, down
to the extreme case of 1B gso_size.

Verify that irrespective of gso_size, udpgso restricts the number of
segments it will generate per call (UDP_MAX_SEGMENTS).

9c7c8a8244 selftests: forwarding: mirror_gre_vlan_bridge_1q: Add more tests
Offloading of mirror-to-gretap in mlxsw is tricky especially in cases
when the gretap underlay involves bridges. Add more tests that exercise
the bridge handling code:

- forbidden_egress tests that check vlan removal on bridge port in the
  underlay packet path
- untagged_egress tests that similarly check "egress untagged"
- fdb_roaming tests that check whether learning FDB on a different port
  is reflected
- stp tests for handling port STP status of bridge egress port

d2f30f5172 Merge git://git.kernel.org/pub/scm/linux/kernel/git/bpf/bpf
Daniel Borkmann says:

====================
pull-request: bpf 2018-05-24

The following pull-request contains BPF updates for your *net* tree.

The main changes are:

1) Fix a bug in the original fix to prevent out of bounds speculation when
   multiple tail call maps from different branches or calls end up at the
   same tail call helper invocation, from Daniel.

2) Two selftest fixes, one in reuseport_bpf_numa where test is skipped in
   case of missing numa support and another one to update kernel config to
   properly support xdp_meta.sh test, from Anders.

 ...

Would be great if you have a chance to merge net into net-next after that.

The verifier fix would be needed later as a dependency in bpf-next for
upcomig work there. When you do the merge there's a trivial conflict on
BPF side with 849fa50662 ("bpf/verifier: refine retval R0 state for
bpf_get_stack helper"): Resolution is to keep both functions, the
do_refine_retval_range() and record_func_map().

b2d6cee117 Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
The bpf syscall and selftests conflicts were trivial
overlapping changes.

The r8169 change involved moving the added mdelay from 'net' into a
different function.

A TLS close bug fix overlapped with the splitting of the TLS state
into separate TX and RX parts.  I just expanded the tests in the bug
fix from "ctx->conf == X" into "ctx->tx_conf == X && ctx->rx_conf
== X".

When a script file that isn't generated uses the variable
TEST_GEN_PROGS_EXTENDED and a 'make -C tools/testing/selftests clean' is
performed the script file gets removed and git shows the file as
deleted. For script files that isn't generated TEST_PROGS_EXTENDED
should be used.

Similar to commit a511858c75 ("selftests: fib_tests: Allow user to run
a specific test"), allow user to run only a subset of the tests using
the TESTS environment variable.

This is useful when not all the tests can pass on a given system.

Example:
# export TESTS="ping_ipv4 ping_ipv6"
# ./bridge_vlan_aware.sh
TEST: ping					[PASS]
TEST: ping6					[PASS]

9413248753 selftests: forwarding: Increase maximum deviation in multipath test
We sometimes observe failures in the test due to too large discrepancy
between the measured and expected ratios. For example:

TEST: ECMP                                                          [FAIL]
        Too large discrepancy between expected and measured ratios
        INFO: Expected ratio 1.00 Measured ratio 1.11

Fix this by allowing an up to 15% deviation between both ratios.

Another possibility is to increase the number of generated flows, but
this will prolong the execution time of the test, which is already quite
high.

aacb0c2e52 selftests: net: tcp_mmap must use TCP_ZEROCOPY_RECEIVE
After prior kernel change, mmap() on TCP socket only reserves VMA.

We have to use getsockopt(fd, IPPROTO_TCP, TCP_ZEROCOPY_RECEIVE, ...)
to perform the transfert of pages from skbs in TCP receive queue into such VMA.

struct tcp_zerocopy_receive {
	__u64 address;		/* in: address of mapping */
	__u32 length;		/* in/out: number of bytes to map/mapped */
	__u32 recv_skip_hint;	/* out: amount of bytes to skip */
};

After a successful getsockopt(...TCP_ZEROCOPY_RECEIVE...), @length contains
number of bytes that were mapped, and @recv_skip_hint contains number of bytes
that should be read using conventional read()/recv()/recvmsg() system calls,
to skip a sequence of bytes that can not be mapped, because not properly page
aligned.
