udp: only do GSO if # of segs > 1

2019-10-07T16:57:24+00:00

[ Upstream commit 4094871db1d65810acab3d57f6089aa39ef7f648 ]

Prior to this change an application sending <= 1MSS worth of data and
enabling UDP GSO would fail if the system had SW GSO enabled, but the
same send would succeed if HW GSO offload is enabled. In addition to this
inconsistency the error in the SW GSO case does not get back to the
application if sending out of a real device so the user is unaware of this
failure.

With this change we only perform GSO if the # of segments is > 1 even
if the application has enabled segmentation. I've also updated the
relevant udpgso selftests.

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

2019-09-21T05:16:52+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: fib_rule_tests: use pre-defined DEV_ADDR

[ Upstream commit 34632975cafdd07ce80e85c2eda4e9c16b5f2faa ]

DEV_ADDR is defined but not used. Use it in address setting.
Do the same with IPv6 for consistency.

selftests/kvm: make platform_info_test pass on AMD

[ 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

2019-09-10T09:33:51+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: forwarding: gre_multipath: Fix flower filters

2019-08-29T06:28:30+00:00

[ Upstream commit 1be79d89b7ae96e004911bd228ce8c2b5cc6415f ]

The TC filters used in the test do not work with veth devices because the
outer Ethertype is 802.1Q and not IPv4. The test passes with mlxsw
netdevs since the hardware always looks at "The first Ethertype that
does not point to either: VLAN, CNTAG or configurable Ethertype".

Fix this by matching on the VLAN ID instead, but on the ingress side.
The reason why this is not performed at egress is explained in the
commit cited below.

[ Upstream commit efa7b79f675da0efafe3f32ba0d6efe916cf4867 ]

selftests/bpf: fix sendmsg6_prog on s390

2019-08-29T06:28:28+00:00

[ Upstream commit c8eee4135a456bc031d67cadc454e76880d1afd8 ]

"sendmsg6: rewrite IP & port (C)" fails on s390, because the code in
sendmsg_v6_prog() assumes that (ctx->user_ip6[0] & 0xFFFF) refers to
leading IPv6 address digits, which is not the case on big-endian
machines.

Since checking bitwise operations doesn't seem to be the point of the
test, replace two short comparisons with a single int comparison.

cgroup: kselftest: relax fs_spec checks

2019-08-06T17:06:55+00:00

commit b59b1baab789eacdde809135542e3d4f256f6878 upstream.

On my laptop most memcg kselftests were being skipped because it claimed
cgroup v2 hierarchy wasn't mounted, but this isn't correct.  Instead, it
seems current systemd HEAD mounts it with the name "cgroup2" instead of
"cgroup":

    % grep cgroup /proc/mounts
    cgroup2 /sys/fs/cgroup cgroup2 rw,nosuid,nodev,noexec,relatime,nsdelegate 0 0

I can't think of a reason to need to check fs_spec explicitly
since it's arbitrary, so we can just rely on fs_vfstype.

After these changes, `make TARGETS=cgroup kselftest` actually runs the
cgroup v2 tests in more cases.
