2021-10-18selftests: KVM: Fix kvm device helper ioctl assertionsOliver Upton
The KVM_CREATE_DEVICE and KVM_{GET,SET}_DEVICE_ATTR ioctls are defined to return a value of zero on success. As such, tighten the assertions in the helper functions to only pass if the return code is zero.

2021-10-17KVM: arm64: selftests: arch_timer: Support vCPU migrationRaghavendra Rao Ananta
Since the timer stack (hardware and KVM) is per-CPU, there are potential chances for races to occur when the scheduler decides to migrate a vCPU thread to a different physical CPU. Hence, include an option to stress-test this part as well by forcing the vCPUs to migrate across physical CPUs in the system at a particular rate. Originally, the bug for the fix with commit 3134cc8beb69d0d ("KVM: arm64: vgic: Resample HW pending state on deactivation") was discovered using arch_timer test with vCPU migrations and can be easily reproduced.

2021-10-16mptcp: increase default max additional subflows to 2Paolo Abeni
The current default does not allowing additional subflows, mostly as a safety restriction to avoid uncontrolled resource consumption on busy servers. Still the system admin and/or the application have to opt-in to MPTCP explicitly. After that, they need to change (increase) the default maximum number of additional subflows. Let set that to reasonable default, and make end-users life easier. Additionally we need to update some self-tests accordingly.

2021-10-15vsock_diag_test: remove free_sock_stat() call in test_no_socketsStefano Garzarella
In `test_no_sockets` we don't expect any sockets, indeed check_no_sockets() prints an error and exits if `sockets` list is not empty, so free_sock_stat() call is unnecessary since it would only be called when the `sockets` list is empty. This was discovered by a strange warning printed by gcc v11.2.1: In file included from ../../include/linux/list.h:7, from vsock_diag_test.c:18: vsock_diag_test.c: In function ‘test_no_sockets’: ../../include/linux/kernel.h:35:45: error: array subscript ‘struct vsock_stat[0]’ is partly outside array bound s of ‘struct list_head[1]’ [-Werror=array-bounds] 35 | const typeof(((type *)0)->member) * __mptr = (ptr); \ | ^~~~~~ ../../include/linux/list.h:352:9: note: in expansion of macro ‘container_of’ 352 | container_of(ptr, type, member) | ^~~~~~~~~~~~ ../../include/linux/list.h:393:9: note: in expansion of macro ‘list_entry’ 393 | list_entry((pos)->member.next, typeof(*(pos)), member) | ^~~~~~~~~~ ../../include/linux/list.h:522:21: note: in expansion of macro ‘list_next_entry’ 522 | n = list_next_entry(pos, member); \ | ^~~~~~~~~~~~~~~ vsock_diag_test.c:325:9: note: in expansion of macro ‘list_for_each_entry_safe’ 325 | list_for_each_entry_safe(st, next, sockets, list) { | ^~~~~~~~~~~~~~~~~~~~~~~~ In file included from vsock_diag_test.c:18: vsock_diag_test.c:333:19: note: while referencing ‘sockets’ 333 | LIST_HEAD(sockets); | ^~~~~~~ ../../include/linux/list.h:23:26: note: in definition of macro ‘LIST_HEAD’ 23 | struct list_head name = LIST_HEAD_INIT(name) It seems related to some compiler optimization and assumption about the empty `sockets` list, since this warning is printed only with -02 or -O3. Also removing `exit(1)` from check_no_sockets() makes the warning disappear since in that case free_sock_stat() can be reached also when the list is not empty.

Add a test case that demonstrates port shadowing via UDP. ns2 sends packet to ns1, from source port used by a udp service on the router, ns0. Then, ns1 sends packet to ns0:service, but that ends up getting forwarded to ns2. Also add three test cases that demonstrate mitigations: 1. disable use of $port as source from 'unstrusted' origin 2. make the service untracked. This prevents masquerade entries from having any effects. 3. add forced PAT via 'random' mode to translate the "wrong" sport into an acceptable range.

2021-10-11KVM: arm64: selftests: Add test for legacy GICv3 REDIST base partially above ↵Ricardo Koller
IPA range Add a new test into vgic_init which checks that the first vcpu fails to run if there is not sufficient REDIST space below the addressable IPA range. This only applies to the KVM_VGIC_V3_ADDR_TYPE_REDIST legacy API as the required REDIST space is not know when setting the DIST region. Note that using the REDIST_REGION API results in a different check at first vcpu run: that the number of redist regions is enough for all vcpus. And there is already a test for that case in, the first step of test_v3_new_redist_regions.

2021-10-11KVM: arm64: selftests: Add tests for GIC redist/cpuif partially above IPA rangeRicardo Koller
Add tests for checking that KVM returns the right error when trying to set GICv2 CPU interfaces or GICv3 Redistributors partially above the addressable IPA range. Also tighten the IPA range by replacing KVM_CAP_ARM_VM_IPA_SIZE with the IPA range currently configured for the guest (i.e., the default). The check for the GICv3 redistributor created using the REDIST legacy API is not sufficient as this new test only checks the check done using vcpus already created when setting the base. The next commit will add the missing test which verifies that the KVM check is done at first vcpu run.

As a preparation for the next commits which will add some tests for GICv2, make aarch64/vgic_init GIC version agnostic. Add a new generic run_tests function(gic_dev_type) that starts all applicable tests using GICv3 or GICv2. GICv2 tests are attempted if GICv3 is not available in the system. There are currently no GICv2 tests, but the test passes now in GICv2 systems.

2021-10-08selftests/bpf: Skip verifier tests that fail to load with ENOTSUPPIlya Leoshkevich
The verifier tests added in commit c48e51c8b07a ("bpf: selftests: Add selftests for module kfunc support") fail on s390, since the JIT does not support calling kernel functions. This is most likely an issue for all the other non-Intel arches, as well as on Intel with !CONFIG_DEBUG_INFO_BTF or !CONFIG_BPF_JIT. Trying to check for messages from all the possible add_kfunc_call() failure cases in test_verifier looks pointless, so do a much simpler thing instead: just like it's already done in do_prog_test_run(), skip the tests that fail to load with ENOTSUPP.
