2019-08-06selftests/bpf: add loop test 4Alexei Starovoitov2-0/+19
Add a test that returns a 'random' number between [0, 2^20) If state pruning is not working correctly for loop body the number of processed insns will be 2^20 * num_of_insns_in_loop_body and the program will be rejected.

2019-08-05bpf: fix XDP vlan selftests test_xdp_vlan.shJesper Dangaard Brouer1-6/+36
Change BPF selftest test_xdp_vlan.sh to (default) use generic XDP. This selftest was created together with a fix for generic XDP, in commit 297249569932 ("net: fix generic XDP to handle if eth header was mangled"). And was suppose to catch if generic XDP was broken again. The tests are using veth and assumed that veth driver didn't support native driver XDP, thus it used the (ip link set) 'xdp' attach that fell back to generic-XDP. But veth gained native-XDP support in 948d4f214fde ("veth: Add driver XDP"), which caused this test script to use native-XDP.

2019-08-05selftests: netfilter: extend flowtable test script for ipsecFlorian Westphal1-0/+48
'flow offload' expression should not offload flows that will be subject to ipsec, but it does. This results in a connectivity blackhole for the affected flows -- first packets will go through (offload happens after established state is reached), but all remaining ones bypass ipsec encryption and are thus discarded by the peer. This can be worked around by adding "rt ipsec exists accept" before the 'flow offload' rule matches. This test case will fail, support for such flows is added in next patch.

Add nettest - a simple program with an implementation for various networking APIs. nettest is used for tcp, udp and raw functional tests for both IPv4 and IPv6. Point of this command versus existing utilities: - controlled implementation of the APIs and the order in which they are called, - ability to verify ingress device, local and remote addresses, - timeout for controlled test length, - ability to discriminate a timeout from a system call failure, and - simplicity with test scripts. The command returns: 0 on success, 1 for any system call failure, and 2 on timeout. Signed-off-by: David Ahern <[email protected]> Signed-off-by: David S. Miller <[email protected]>
2019-08-03cgroup: kselftest: relax fs_spec checksChris Down1-2/+1
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.

2019-08-02KVM: selftests: Enable dirty_log_test on s390xThomas Huth2-7/+53
To run the dirty_log_test on s390x, we have to make sure that we access the dirty log bitmap with little endian byte ordering and we have to properly align the memslot of the guest. Also all dirty bits of a segment are set once on s390x when one of the pages of a segment are written to for the first time, so we have to make sure that we touch all pages during the first iteration to keep the test in sync here. DEFAULT_GUEST_TEST_MEM needs an adjustment, too. On some s390x distributions, the ELF binary is linked to address 0x80000000, so we have to avoid that our test region overlaps into this area. 0xc0000000 seems to be a good alternative that should work on x86 and aarch64, too.

2019-08-02KVM: selftests: Split ucall.c into architecture specific filesThomas Huth6-168/+173
The way we exit from a guest to userspace is very specific to the architecture: On x86, we use PIO, on aarch64 we are using MMIO and on s390x we're going to use an instruction instead. The possibility to select a type via the ucall_type_t enum is currently also completely unused, so the code in ucall.c currently looks more complex than required. Let's split this up into architecture specific ucall.c files instead, so we can get rid of the #ifdefs and the unnecessary ucall_type_t handling.

Since commit 05f415715ce45 ("rcu: Speed up expedited GPs when interrupting RCU reader") in v5.0 and through v5.1, booting with the threadirqs kernel boot parameter caused self-deadlocks, which can be reproduced using the following command on an 8-CPU system: tools/testing/selftests/rcutorture/bin/kvm.sh --duration 5 --configs "TREE03" --bootargs "threadirqs" This commit therefore adds the threadirqs kernel boot parameter to the TREE03 rcutorture scenario in order to more quickly detect future similar bugs.

By default, if test had no errors, the only output will be a single line with test number, name, and verdict at the end, e.g.: #31 xdp:OK If test had any errors, all log output captured during test execution will be output after test completes. It's possible to force output of log with `-v` (`--verbose`) option, in which case output won't be buffered and will be output immediately.
