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: net: fix/improve ip_defrag selftest

2019-02-27T09:09:44Z

[ Upstream commit 3271a4821882a64214acc1bd7b173900ec70c9bf ] Commit ade446403bfb ("net: ipv4: do not handle duplicate fragments as overlapping") changed IPv4 defragmentation so that duplicate fragments, as well as _some_ fragments completely covered by previously delivered fragments, do not lead to the whole frag queue being discarded. This makes the existing ip_defrag selftest flaky. This patch * makes sure that negative IPv4 defrag tests generate truly overlapping fragments that trigger defrag queue drops; * tests that duplicate IPv4 fragments do not trigger defrag queue drops; * makes a couple of minor tweaks to the test aimed at increasing its code coverage and reduce flakiness.

net/ipv6: Allow onlink routes to have a device mismatch if it is the default route

2018-10-24T21:36:38Z

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. Signed-off-by: David S. Miller

selftests: pmtu: Allow selection of single tests

2018-10-16T05:37:28Z

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.

Daniel Borkmann says: ==================== 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. ==================== Signed-off-by: David S.
