[PATCH AUTOSEL 5.1 40/59] selftests: set sysctl bc_forwarding properly in router_broadcast.sh

by Sasha Levin

From: Xin Long <lucien.xin(a)gmail.com> [ Upstream commit 67c0aaa1eaec60e9dab301012bdebe6726ae04bd ] 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.

kselftest build broken?

by Dmitry Vyukov

Hi, I've tried to build kselftests for several years now, but I always find the build broken. Which makes me wonder if the instructions are broken or something. I follow the instructions in Documentation/dev-tools/kselftest.rst and start with "make -C tools/testing/selftests". Here is the errors I get on the upstream commit 16d72dd4891fecc1e1bf7ca193bb7d5b9804c038: error: unable to create target: 'No available targets are compatible with triple "bpf"' 1 error generated.
