2019-04-16selftests: kvm: add a selftest for SMMVitaly Kuznetsov4-6/+191
Add a simple test for SMM, based on VMX. The test implements its own sync between the guest and the host as using our ucall library seems to be too cumbersome: SMI handler is happening in real-address mode. This patch also fixes KVM_SET_NESTED_STATE to happen after KVM_SET_VCPU_EVENTS, in fact it places it last. This is because KVM needs to know whether the processor is in SMM or not.

2019-04-15netfilter: nat: fix icmp id randomizationFlorian Westphal1-9/+27
Sven Auhagen reported that a 2nd ping request will fail if 'fully-random' mode is used. Reason is that if no proto information is given, min/max are both 0, so we set the icmp id to 0 instead of chosing a random value between 0 and 65535. Update test case as well to catch this, without fix this yields: [..] ERROR: cannot ping ns1 from ns2 with ip masquerade fully-random (attempt 2) ERROR: cannot ping ns1 from ns2 with ipv6 masquerade fully-random (attempt 2) ... becaus 2nd ping clashes with existing 'id 0' icmp conntrack and gets dropped.

2019-04-13selftests: netfilter: check icmp pkttoobig errors are set as relatedFlorian Westphal2-1/+284
When an icmp error such as pkttoobig is received, conntrack checks if the "inner" header (header of packet that did not fit link mtu) is matches an existing connection, and, if so, sets that packet as being related to the conntrack entry it found. It was recently reported that this "related" setting also works if the inner header is from another, different connection (i.e., artificial/forged icmp error). Add a test, followup patch will add additional "inner dst matches outer dst in reverse direction" check before setting related state.

A couple of tests are verifying a route has been removed. The helper expects the prefix as the first part of the expected output. When checking that a route has been deleted the prefix is empty leading to an invalid ip command: $ ip ro ls match Command line is not complete. Try option "help" Fix by moving the comparison of expected output and output to a new function that is used by both check_route and check_route6. Use the new helper for the 2 checks on route removal.

Implementation of function rhashtable_insert_fast() check if its internal helper function __rhashtable_insert_fast() returns non-NULL pointer and seemingly return -EEXIST in such case. However, since __rhashtable_insert_fast() is called with NULL key pointer, it never actually checks for duplicates, which means that -EEXIST is never returned to the user. Use rhashtable_lookup_insert_fast() hash table API instead.

2019-04-11selftests: bpf: add selftest for __sk_buff context in BPF_PROG_TEST_RUNStanislav Fomichev2-0/+110
Simple test that sets cb to {1,2,3,4,5} and priority to 6, runs bpf program that fails if cb is not what we expect and increments cb[i] and priority. When the test finishes, we check that cb is now {2,3,4,5,6} and priority is 7. We also test the sanity checks: * ctx_in is provided, but ctx_size_in is zero (same for ctx_out/ctx_size_out) * unexpected non-zero fields in __sk_buff return EINVAL Signed-off-by: Stanislav Fomichev <sdf@google.com> Acked-by: Martin KaFai Lau <kafai@fb.com> Signed-off-by: Daniel Borkmann <daniel@iogearbox.net>

2019-04-06selftests: forwarding: test for bridge mcast traffic after report and leaveNikolay Aleksandrov1-0/+152
This test is split in two, the first part checks if a report creates a corresponding mdb entry and if traffic is properly forwarded to it, and the second part checks if the mdb entry is deleted after a leave and if traffic is *not* forwarded to it. Since the mcast querier is enabled we should see standard mcast snooping bridge behaviour. Signed-off-by: Nikolay Aleksandrov <nikolay@cumulusnetworks.com> Signed-off-by: David S.
