2021-10-17KVM: arm64: selftests: Add basic GICv3 supportRaghavendra Rao Ananta6-1/+448
Add basic support for ARM Generic Interrupt Controller v3. The support provides guests to setup interrupts. The work is inspired from kvm-unit-tests and the kernel's GIC driver (drivers/irqchip/irq-gic-v3.c).

2021-10-17KVM: arm64: selftests: Add guest support to get the vcpuidRaghavendra Rao Ananta2-0/+8
At times, such as when in the interrupt handler, the guest wants to get the vcpuid that it's running on to pull the per-cpu private data. As a result, introduce guest_get_vcpuid() that returns the vcpuid of the calling vcpu. The interface is architecture independent, but defined only for arm64 as of now.

With the inclusion of sysreg.h, that brings in system register encodings, it would be redundant to re-define register encodings again in processor.h to use it with ARM64_SYS_REG for the KVM functions such as set_reg() or get_reg(). Hence, add helper macro, ARM64_SYS_KVM_REG, that converts SYS_* definitions in sysreg.h into ARM64_SYS_REG definitions. Also replace all the users of ARM64_SYS_REG, relying on the encodings created in processor.h, with ARM64_SYS_KVM_REG and remove the definitions.

2021-10-16mptcp: increase default max additional subflows to 2Paolo Abeni2-4/+7
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 Garzarella1-2/+0
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 tests for GIC redist/cpuif partially above IPA rangeRicardo Koller1-12/+26
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.

2021-10-11KVM: arm64: selftests: Make vgic_init gic version agnosticRicardo Koller1-61/+95
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.

Cleanup dummy headers in tools/bootconfig/include except for tools/bootconfig/include/linux/bootconfig.h.

2021-10-08selftests/bpf: Skip verifier tests that fail to load with ENOTSUPPIlya Leoshkevich1-1/+11
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.
