Skip selftests that require EPT support in the VM when it is not available. For example, if running on a machine where kvm_intel.ept=N since KVM does not offer EPT support to guests if EPT is not supported on the host. This commit causes vmx_dirty_log_test to be skipped instead of failing on hosts where kvm_intel.ept=N.

Changing return value of kprobe's version of bpf_get_func_ip to return zero if the attach address is not on the function's entry point. For kprobes attached in the middle of the function we can't easily get to the function address especially now with the CONFIG_X86_KERNEL_IBT support.

2022-09-26bpf: Adjust kprobe_multi entry_ip for CONFIG_X86_KERNEL_IBTJiri Olsa1-3/+1
Martynas reported bpf_get_func_ip returning +4 address when CONFIG_X86_KERNEL_IBT option is enabled. When CONFIG_X86_KERNEL_IBT is enabled we'll have endbr instruction at the function entry, which screws return value of bpf_get_func_ip() helper that should return the function address. There's short term workaround for kprobe_multi bpf program made by Alexei [1], but we need this fixup also for bpf_get_attach_cookie, that returns cookie based on the entry_ip value. Moving the fixup in the fprobe handler, so both bpf_get_func_ip and bpf_get_attach_cookie get expected function address when CONFIG_X86_KERNEL_IBT option is enabled. Also renaming kprobe_multi_link_handler entry_ip argument to fentry_ip so it's clearer this is an ftrace __fentry__ ip. [1] commit 7f0059b58f02 ("selftests/bpf: Fix kprobe_multi test.")

2022-09-26selftests: net: tsn_lib: run phc2sys in automatic modeVladimir Oltean2-6/+3
We can make the phc2sys helper not only synchronize a PHC to CLOCK_REALTIME, which is what it currently does, but also CLOCK_REALTIME to a PHC, which is going to be needed in distributed TSN tests. Instead of making the complexity of the arguments passed to phc2sys_start() explode, we can let it figure out the sync direction automatically, based on ptp4l's port states. Towards that goal, pass just the path to the desired ptp4l instance's UNIX domain socket, and remove the $if_name argument (from which it derives the PHC). Also adapt the one caller from the ocelot psfp.sh test. In the case of psfp.sh, phc2sys_start is able to properly figure out that CLOCK_REALTIME is the source clock and swp1's PHC is the destination, because of the way in which ptp4l_start for the UDS_ADDRESS_SWP1 was called: with slave_only=false, so it will always win the BMCA and always become the sync master between itself and $h1.

2022-09-26selftests: net: tsn_lib: allow running ptp4l on multiple interfacesVladimir Oltean1-8/+19
Switch ports will want to act as Boundary Clocks, which are configured using ptp4l by specifying the "-i" argument multiple times. Since we track a log file and a pid file for each ptp4l instance, and we want to be compatible with the existing single-port callers of ptp4l_start and ptp4l_stop, pass the interface list as a single string of space-separated values. Based on this, we create a label for each ptp4l instance, where the spaces are replaced with underscores (ptp4l_start "eth0 eth1" generates "ptp4l_pid_eth0_eth1").

The extra_args argument ($3) of isochron_recv_start is overwritten with uds ($2), if that argument exists. This is currently not a problem, because the only TSN selftest (ocelot/psfp.sh) omits remote sync so it does not specify to the receiver a UNIX domain socket for ptp4l.

Require KVM_CAP_VM_DISABLE_NX_HUGE_PAGES for the entire NX hugepage test instead of skipping the "disable" subtest if the capability isn't supported by the host kernel. While the "enable" subtest does provide value when the capability isn't supported, silently providing only half the promised coveraged is undesirable, i.e. it's better to skip the test so that the user knows something. Alternatively, the test could print something to alert the user instead of silently skipping the subtest, but that would encourage other tests to follow suit, and it's not clear that it's desirable to take selftests in that direction. And if selftests do head down the path of skipping subtests, such behavior needs first-class support in the framework. Opportunistically convert other test preconditions to TEST_REQUIRE().

2022-09-23selftests/bpf: allow to adjust BPF verifier log level in veristatAndrii Nakryiko1-1/+13
Add -l (--log-level) flag to override default BPF verifier log lever. This only matters in verbose mode, which is the mode in which veristat emits verifier log for each processed BPF program. This is important because for successfully verified BPF programs log_level 1 is empty, as BPF verifier truncates all the successfully verified paths. So -l2 is the only way to actually get BPF verifier log in practice. It looks sometihng like this: [vmuser@archvm bpf]$ sudo ./veristat xdp_tx.bpf.o -vl2 Processing 'xdp_tx.bpf.o'...

2022-09-23selftests/bpf: make veristat skip non-BPF and failing-to-open BPF objectsAndrii Nakryiko1-8/+70
Make veristat ignore non-BPF object files. This allows simpler mass-verification (e.g., `sudo ./veristat *.bpf.o` in selftests/bpf directory). Note that `sudo ./veristat *.o` would also work, but with selftests's multiple copies of BPF object files (.bpf.o and .bpf.linked{1,2,3}.o) it's 4x slower. Also, given some of BPF object files could be incomplete in the sense that they are meant to be statically linked into final BPF object file (like linked_maps, linked_funcs, linked_vars), note such instances in stderr, but proceed anyways. This seems like a better trade off between completely silently ignoring BPF object file and aborting mass-verification altogether.

2022-09-23selftests/bpf: Simplify cgroup_hierarchical_stats selftestYosry Ahmed2-220/+131
The cgroup_hierarchical_stats selftest is complicated. It has to be, because it tests an entire workflow of recording, aggregating, and dumping cgroup stats. However, some of the complexity is unnecessary. The test now enables the memory controller in a cgroup hierarchy, invokes reclaim, measure reclaim time, THEN uses that reclaim time to test the stats collection and aggregation. We don't need to use such a complicated stat, as the context in which the stat is collected is orthogonal. Simplify the test by using a simple stat instead of reclaim time, the total number of times a process has ever entered a cgroup. This makes the test simpler and removes the dependency on the memory controller and the memory reclaim interface.
