With the MMCR0 control bit (PMCCEXT) in ISA v3.1, read access to group B registers is restricted when MMCR0 PMCC=0b00. In other platforms (like power9), the older behaviour works where group B PMU SPRs are readable. Patch creates a selftest which verifies that the test takes a SIGILL when attempting to read PMU registers via helper function "dump_ebb_state" for ISA v3.1.

2021-06-17selftests/powerpc: Fix "no_handler" EBB selftestAthira Rajeev1-2/+0
The "no_handler_test" in ebb selftests attempts to read the PMU registers twice via helper function "dump_ebb_state". First dump is just before closing of event and the second invocation is done after closing of the event. The original intention of second dump_ebb_state was to dump the state of registers at the end of the test when the counters are frozen. But this will be achieved with the first call itself since sample period is set to low value and PMU will be frozen by then. Hence patch removes the dump which was done before closing of the event.

2021-06-14bpf, selftests: Adjust few selftest outcomes wrt unreachable codeDaniel Borkmann8-8/+53
In almost all cases from test_verifier that have been changed in here, we've had an unreachable path with a load from a register which has an invalid address on purpose. This was basically to make sure that we never walk this path and to have the verifier complain if it would otherwise. Change it to match on the right error for unprivileged given we now test these paths under speculative execution. There's one case where we match on exact # of insns_processed. Due to the extra path, this will of course mismatch on unprivileged. Thus, restrict the test->insn_processed check to privileged-only. In one other case, we result in a 'pointer comparison prohibited' error. This is similarly due to verifying an 'invalid' branch where we end up with a value pointer on one side of the comparison.

2021-06-14ipv4: Fix device used for dst_alloc with local routesDavid Ahern1-0/+25
Oliver reported a use case where deleting a VRF device can hang waiting for the refcnt to drop to 0. The root cause is that the dst is allocated against the VRF device but cached on the loopback device. The use case (added to the selftests) has an implicit VRF crossing due to the ordering of the FIB rules (lookup local is before the l3mdev rule, but the problem occurs even if the FIB rules are re-ordered with local after l3mdev because the VRF table does not have a default route to terminate the lookup). The end result is is that the FIB lookup returns the loopback device as the nexthop, but the ingress device is in a VRF. The mismatch causes the dst alloc against the VRF device but then cached on the loopback. The fix is to bring the trick used for IPv6 (see ip6_rt_get_dev_rcu): pick the dst alloc device based the fib lookup result but with checks that the result has a nexthop device (e.g., not an unreachable or prohibit entry).

Add the infrastructure needed to enable exception handling in aarch64 selftests. The exception handling defaults to an unhandled-exception handler which aborts the test, just like x86.

2021-06-14KVM: selftests: Introduce UCALL_UNHANDLED for unhandled vector reportingRicardo Koller3-13/+9
x86, the only arch implementing exception handling, reports unhandled vectors using port IO at a specific port number. This replicates what ucall already does. Introduce a new ucall type, UCALL_UNHANDLED, for guests to report unhandled exceptions. Then replace the x86 unhandled vector exception reporting to use it instead of port IO. This new ucall type will be used in the next commits by arm64 to report unhandled vectors as well.

2021-06-14KVM: selftests: Complete x86_64/sync_regs_test ucallRicardo Koller1-1/+6
The guest in sync_regs_test does raw ucalls by directly accessing the ucall IO port. It makes these ucalls without setting %rdi to a `struct ucall`, which is what a ucall uses to pass messages. The issue is that if the host did a get_ucall (the receiver side), it would try to access the `struct ucall` at %rdi=0 which would lead to an error ("No mapping for vm virtual address, gva: 0x0"). This issue is currently benign as there is no get_ucall in sync_regs_test; however, that will change in the next commit as it changes the unhandled exception reporting mechanism to use ucalls. In that case, every vcpu_run is followed by a get_ucall to check if the guest is trying to report an unhandled exception. Fix this in advance by setting %rdi to a UCALL_NONE struct ucall for the sync_regs_test guest. Tested with gcc-[8,9,10], and clang-[9,11].

In the commit referenced below, a check was added to devlink_lib that asserts the existence of a devlink device referenced by $DEVLINK_DEV. Unfortunately, several netdevsim tests point DEVLINK_DEV at a device that does not exist at the time that devlink_lib is sourced. Thus these tests spuriously fail. Fix this by introducing an override. By setting DEVLINK_DEV to an empty string, the user declares their intention to handle DEVLINK_DEV management on their own. In all netdevsim tests that use devlink_lib and set DEVLINK_DEV, set instead an empty DEVLINK_DEV just before sourcing devlink_lib, and set it to the correct value right afterwards.

2021-06-08selftests: kvm: Add support for customized slot0 memory sizeZhenzhong Duan5-15/+45
Until commit 39fe2fc96694 ("selftests: kvm: make allocation of extra memory take effect", 2021-05-27), parameter extra_mem_pages was used only to calculate the page table size for all the memory chunks, because real memory allocation happened with calls of vm_userspace_mem_region_add() after vm_create_default(). Commit 39fe2fc96694 however changed the meaning of extra_mem_pages to the size of memory slot 0. This makes the memory allocation more flexible, but makes it harder to account for the number of pages needed for the page tables. For example, memslot_perf_test has a small amount of memory in slot 0 but a lot in other slots, and adding that memory twice (both in slot 0 and with later calls to vm_userspace_mem_region_add()) causes an error that was fixed in commit 000ac4295339 ("selftests: kvm: fix overlapping addresses in memslot_perf_test", 2021-05-29) Since both uses are sensible, add a new parameter slot0_mem_pages to vm_create_with_vcpus() and some comments to clarify the meaning of slot0_mem_pages and extra_mem_pages. With this change, memslot_perf_test can go back to passing the number of memory pages as extra_mem_pages.

2021-06-08KVM: selftests: introduce P47V64 for s390xChristian Borntraeger2-1/+7
s390x can have up to 47bits of physical guest and 64bits of virtual address bits. Add a new address mode to avoid errors of testcases going beyond 47bits.

2021-06-07selftests: timers: rtcpie: skip test if default RTC device does not existPo-Hsu Lin1-1/+9
This test will require /dev/rtc0, the default RTC device, or one specified by user to run. Since this default RTC is not guaranteed to exist on all of the devices, so check its existence first, otherwise skip this test with the kselftest skip code 4. Without this patch this test will fail like this on a s390x zVM: $ selftests: timers: rtcpie $ /dev/rtc0: No such file or directory not ok 1 selftests: timers: rtcpie # exit=22 With this patch: $ selftests: timers: rtcpie $ Default RTC /dev/rtc0 does not exist. Test Skipped! not ok 9 selftests: timers: rtcpie # SKIP Fixed up change log so "With this patch" text doesn't get dropped.

2021-06-07selftests: lib.mk: Also install "config" and "settings"Kees Cook1-0/+1
Installed seccomp tests would time out because the "settings" file was missing. Install both "settings" (needed for proper test execution) and "config" (needed for informational purposes) with the other test targets.

2021-06-07selftests: splice: Adjust for handler fallback removalKees Cook1-21/+98
Some pseudo-filesystems do not have an explicit splice fops since adding commit 36e2c7421f02 ("fs: don't allow splice read/write without explicit ops"), and now will reject attempts to use splice() in those filesystem paths.

This silences a static checker warning due to the unusual macro construction of EXPECT_*() by adding explicit {}s around the enclosing while loop.

2021-06-07selftests/resctrl: Fix incorrect parsing of option "-t"Xiaochen Shen2-3/+3
Resctrl test suite accepts command line argument "-t" to specify the unit tests to run in the test list (e.g., -t mbm,mba,cmt,cat) as documented in the help. When calling strtok() to parse the option, the incorrect delimiters argument ":\t" is used. As a result, passing "-t mbm,mba,cmt,cat" throws an invalid option error. Fix this by using delimiters argument "," instead of ":\t" for parsing of unit tests list. At the same time, remove the unnecessary "spaces" between the unit tests in help documentation to prevent confusion.
