selftests: net: use LDLIBS instead of LDFLAGS

2019-03-13T21:04:04Z

[ Upstream commit 870f193d48c25a97d61a8e6c04e3c29a2c606850 ] 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.

selftests: add headers_install to lib.mk

2018-09-05T14:12:09Z

If the kernel headers aren't installed we can't build all the tests. Add a new make target rule 'khdr' in the file lib.mk to generate the kernel headers and that gets include for every test-dir Makefile that includes lib.mk If the testdir in turn have its own sub-dirs the top_srcdir needs to be set to the linux-rootdir to be able to generate the kernel headers.

selftests/net: add ip_defrag selftest

2018-08-30T02:49:36Z

This test creates a raw IPv4 socket, fragments a largish UDP datagram and sends the fragments out of order. Then repeats in a loop with different message and fragment lengths. Then does the same with overlapping fragments (with overlapping fragments the expectation is that the recv times out). Tested: root@# time ./ip_defrag.sh ipv4 defrag PASS ipv4 defrag with overlaps PASS real 1m7.679s user 0m0.628s sys 0m2.242s A similar test for IPv6 is to follow.

selftests: tls: add selftests for TLS sockets

2018-07-16T20:33:10Z

Add selftests for tls socket. Tests various iov and message options, poll blocking and nonblocking behavior, partial message sends / receives, and control message data. Tests should pass regardless of if TLS is enabled in the kernel or not, and print a warning message if not. Signed-off-by: Dave Watson Signed-off-by: David S. Miller

selftests/net: add packet socket packet_snd test

2018-06-04T13:50:01Z

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. Signed-off-by: Willem de Bruijn Signed-off-by: David S. Miller

selftests/net: enable msg_zerocopy test

2018-06-04T13:49:39Z

The existing msg_zerocopy test takes additional protocol arguments. Add a variant that takes no arguments and runs all supported variants. Call this from kselftest. Signed-off-by: Willem de Bruijn Signed-off-by: David S. Miller

selftests: net: initial fib rule tests

2018-05-23T19:14:12Z

This adds a first set of tests for fib rule match/action for ipv4 and ipv6. Initial tests only cover action lookup table. can be extended to cover other actions in the future. Uses ip route get to validate the rule lookup. Signed-off-by: Roopa Prabhu Signed-off-by: David S. Miller

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". Signed-off-by: David S. Miller
