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

2018-11-04T13:51:54+00:00

[ Upstream commit 4ed591c8ab44e711e56b8e021ffaf4f407c045f5 ]

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.

selftests: udpgso_bench.sh explicitly requires bash

[ Upstream commit 12a2ea962c06efb30764c47b140d2ec9d3cd7cb0 ]

The udpgso_bench.sh script requires several bash-only features. This
may cause random failures if the default shell is not bash.
Address the above explicitly requiring bash as the script interpreter

selftests: pmtu: properly redirect stderr to /dev/null

[ Upstream commit 0a286afee5a1e8dca86d824209dbd3200294f86f ]

The cleanup function uses "$CMD 2 > /dev/null", which doesn't actually
send stderr to /dev/null, so when the netns doesn't exist, the error
message is shown. Use "2> /dev/null" instead, so that those messages
disappear, as was intended.

Fix cg_read_strcmp()

2018-10-18T07:18:14+00:00

[ Upstream commit 48c2bb0b9cf863e0ed78e269f188ce65b73e0fd1 ]

Fix a couple issues with cg_read_strcmp(), to improve correctness of
cgroup tests
- Fix cg_read_strcmp() always returning 0 for empty "needle" strings.
Previously, this function read to a size = 1 buffer when comparing
against empty strings, which would lead to cg_read_strcmp() comparing
two empty strings.
- Fix a memory leak in cg_read_strcmp()

selftests: add headers_install to lib.mk

[ Upstream commit b2d35fa5fc80c27e868e393dcab4c94a0d71737f ]

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.
