selftests/bpf: add config fragment BPF_JIT

2019-09-21T05:18:32+00:00

[ Upstream commit 0604409df9e04cdec7b08d471c8c1c0c10b5554d ]

When running test_kmod.sh the following shows up

 # sysctl cannot stat /proc/sys/net/core/bpf_jit_enable No such file or directory
 cannot: stat_/proc/sys/net/core/bpf_jit_enable #
 # sysctl cannot stat /proc/sys/net/core/bpf_jit_harden No such file or directory
 cannot: stat_/proc/sys/net/core/bpf_jit_harden #

Rework to enable CONFIG_BPF_JIT to solve "No such file or directory"

selftests/bpf: fix test_cgroup_storage on s390

2019-09-21T05:18:32+00:00

[ Upstream commit 806ce6e2117a42528e7bb979e04e28229b34a612 ]

test_cgroup_storage fails on s390 with an assertion failure: packets are
dropped when they shouldn't. The problem is that BPF_DW packet count is
accessed as BPF_W with an offset of 0, which is not correct on
big-endian machines.

Since the point of this test is not to verify narrow loads/stores,
simply use BPF_DW when working with packet counts.

selftests/bpf: fix "bind{4, 6} deny specific IP & port" on s390

2019-09-21T05:18:28+00:00

[ Upstream commit 27df5c7068bf23cab282dc64b1c9894429b3b8a0 ]

"bind4 allow specific IP & port" and "bind6 deny specific IP & port"
fail on s390 because of endianness issue: the 4 IP address bytes are
loaded as a word and compared with a constant, but the value of this
constant should be different on big- and little- endian machines, which
is not the case right now.

Use __bpf_constant_ntohl to generate proper value based on machine
endianness.

selftests/kvm: make platform_info_test pass on AMD

2019-09-10T09:35:23+00:00

[ Upstream commit e4427372398c31f57450565de277f861a4db5b3b ]

test_msr_platform_info_disabled() generates EXIT_SHUTDOWN but VMCB state
is undefined after that so an attempt to launch this guest again from
test_msr_platform_info_enabled() fails. Reorder the tests to make test
pass.

selftests: kvm: fix state save/load on processors without XSAVE

2019-09-10T09:35:23+00:00

[ Upstream commit 54577e5018a8c0cb79c9a0fa118a55c68715d398 ]

state_test and smm_test are failing on older processors that do not
have xcr0.  This is because on those processor KVM does provide
support for KVM_GET/SET_XSAVE (to avoid having to rely on the older
KVM_GET/SET_FPU) but not for KVM_GET/SET_XCRS.

selftests: kvm: fix vmx_set_nested_state_test

[ Upstream commit c930e19790bbbff31c018009907c813fa0925f63 ]

vmx_set_nested_state_test is trying to use the KVM_STATE_NESTED_EVMCS without
enabling enlightened VMCS first.  Correct the outcome of the test, and actually
test that it succeeds after the capability is enabled.

selftests/bpf: install files test_xdp_vlan.sh

2019-09-06T08:23:29+00:00

[ Upstream commit 3035bb72ee47d494c041465b4add9c6407c832ed ]

When ./test_xdp_vlan_mode_generic.sh runs it complains that it can't
find file test_xdp_vlan.sh.

 # selftests: bpf: test_xdp_vlan_mode_generic.sh

Rework so that test_xdp_vlan.sh gets installed, added to the variable
TEST_PROGS_EXTENDED.
