selftests: Setup for functional tests for fib and socket lookups

2019-08-03T17:42:04+00:00

Initial commit for functional test suite for fib and socket lookups. This commit contains the namespace setup, networking config, test options and other basic infrastructure. Signed-off-by: David Ahern Signed-off-by: David S. Miller

selftests: Add nettest

2019-08-03T17:42:04+00:00

Add nettest - a simple program with an implementation for various networking APIs. nettest is used for tcp, udp and raw functional tests for both IPv4 and IPv6. Point of this command versus existing utilities: - controlled implementation of the APIs and the order in which they are called, - ability to verify ingress device, local and remote addresses, - timeout for controlled test length, - ability to discriminate a timeout from a system call failure, and - simplicity with test scripts. The command returns: 0 on success, 1 for any system call failure, and 2 on timeout. Signed-off-by: David Ahern Signed-off-by: David S. Miller

blackhole_dev: add a selftest

2019-07-02T02:34:46+00:00

Since this is not really a device with all capabilities, this test ensures that it has *enough* to make it through the data path without causing unwanted side-effects (read crash!). Signed-off-by: Mahesh Bandewar Signed-off-by: David S. Miller

selftests/net: add TFO key rotation selftest

2019-05-30T20:41:26+00:00

Demonstrate how the primary and backup TFO keys can be rotated while minimizing the number of client cookies that are rejected. Signed-off-by: Jason Baron Signed-off-by: Christoph Paasch Acked-by: Yuchung Cheng Signed-off-by: David S. Miller

selftests/net: ipv6 flowlabel

2019-05-29T00:18:53+00:00

Test the IPv6 flowlabel control and datapath interfaces: Acquire and release the right to use flowlabels with socket option IPV6_FLOWLABEL_MGR. Then configure flowlabels on send and read them on recv with cmsg IPV6_FLOWINFO. Also verify auto-flowlabel if not explicitly set. This helped identify the issue fixed in commit 95c169251bf73 ("ipv6: invert flowlabel sharing check in process and user mode") Signed-off-by: Willem de Bruijn Signed-off-by: David S. Miller

selftests/net: SO_TXTIME with ETF and FQ

2019-05-24T20:34:40+00:00

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 fb420d5d91c1 ("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 payload:a delay:40 expected:0 (us) SO_TXTIME ipv4 clock monotonic payload:a delay:33 expected:0 (us) SO_TXTIME ipv6 clock monotonic payload:a delay:10120 expected:10000 (us) SO_TXTIME ipv4 clock monotonic payload:a delay:10102 expected:10000 (us) [.. etc ..] OK.

selftests: net: use LDLIBS instead of LDFLAGS

2019-01-28T15:02:12+00:00

reuseport_bpf_numa fails to build due to undefined reference errors: aarch64-linaro-linux-gcc --sysroot=/build/tmp-rpb-glibc/sysroots/hikey -Wall -Wl,--no-as-needed -O2 -g -I../../../../usr/include/ -Wl,-O1 -Wl,--hash-style=gnu -Wl,--as-needed -lnuma reuseport_bpf_numa.c -o /build/tmp-rpb-glibc/work/hikey-linaro-linux/kselftests/4.12-r0/linux-4.12-rc7/tools/testing/selftests/net/reuseport_bpf_numa /tmp/ccfUuExT.o: In function `send_from_node': /build/tmp-rpb-glibc/work/hikey-linaro-linux/kselftests/4.12-r0/linux-4.12-rc7/tools/testing/selftests/net/reuseport_bpf_numa.c:138: undefined reference to `numa_run_on_node' /tmp/ccfUuExT.o: In function `main': /build/tmp-rpb-glibc/work/hikey-linaro-linux/kselftests/4.12-r0/linux-4.12-rc7/tools/testing/selftests/net/reuseport_bpf_numa.c:230: undefined reference to `numa_available' /build/tmp-rpb-glibc/work/hikey-linaro-linux/kselftests/4.12-r0/linux-4.12-rc7/tools/testing/selftests/net/reuseport_bpf_numa.c:233: undefined reference to `numa_max_node' 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. https://lkml.org/lkml/2010/2/10/362 tools/perf: libraries must come after objects Link order matters, use LDLIBS instead of LDFLAGS to properly link against libnuma.
