2020-02-24KVM: selftests: Create a demand paging testBen Gardon
While userfaultfd, KVM's demand paging implementation, is not specific to KVM, having a benchmark for its performance will be useful for guiding performance improvements to KVM. As a first step towards creating a userfaultfd demand paging test, create a simple memory access test, based on dirty_log_test.

2020-02-24KVM: selftests: Introduce num-pages conversion utilitiesAndrew Jones
Guests and hosts don't have to have the same page size. This means calculations are necessary when selecting the number of guest pages to allocate in order to ensure the number is compatible with the host. Provide utilities to help with those calculations and apply them where appropriate. We also revert commit bffed38d4fb5 ("kvm: selftests: aarch64: dirty_log_test: fix unaligned memslot size") and then use vm_adjust_num_guest_pages() there instead.

2020-02-21selftests/bpf: Tests for sockmap/sockhash holding listening socketsJakub Sitnicki
Now that SOCKMAP and SOCKHASH map types can store listening sockets, user-space and BPF API is open to a new set of potential pitfalls. Exercise the map operations, with extra attention to code paths susceptible to races between map ops and socket cloning, and BPF helpers that work with SOCKMAP/SOCKHASH to gain confidence that all works as expected.

2020-02-21bpf, sockmap: Allow inserting listening TCP sockets into sockmapJakub Sitnicki
In order for sockmap/sockhash types to become generic collections for storing TCP sockets we need to loosen the checks during map update, while tightening the checks in redirect helpers. Currently sock{map,hash} require the TCP socket to be in established state, which prevents inserting listening sockets. Change the update pre-checks so the socket can also be in listening state. Since it doesn't make sense to redirect with sock{map,hash} to listening sockets, add appropriate socket state checks to BPF redirect helpers too.

The commits introducing 'mlock-random-test'[1], 'map_fiex_noreplace'[2], and 'thuge-gen'[3] have not added those in the 'run_vmtests' script and thus the 'run_tests' command of kselftests doesn't run those. This commit adds those in the script. 'gup_benchmark' and 'transhuge-stress' are also not included in the 'run_vmtests', but this commit does not add those because those are for performance measurement rather than pass/fail tests.

2020-02-20rcutorture: Set KCSAN Kconfig options to detect more data racesPaul E. McKenney
This commit enables the KCSAN Kconfig options that (1) detect data races between reads and writes even when the writes do not change the variable's value and (2) detect data races involving plain C-language writes. These changes only affect scripted rcutorture runs and can be overridden using the kvm.sh --kconfig argument. Signed-off-by: Paul E. McKenney <paulmck@kernel.org>
2020-02-20rcutorture: Make kvm-find-errors.sh abort on bad directoryPaul E. McKenney

2020-02-20rcutorture: Summarize summary of build and run resultsPaul E. McKenney
When running the default list of tests, the run summary of a successful (that is, failed to find any errors) run fits easily on a 24-line screen. But a run with something like "--configs '5*CFLIST'" will be 80 lines long, and it is all too easy to miss a failure message when scrolling back. This commit therefore prints out the number of runs with failing builds or runtime failures, but only if there are any such failures. For example, a run with a single build error and a single runtime error would print two lines like this: 1 runs with build errors. 1 runs with runtime errors. Signed-off-by: Paul E. McKenney <paulmck@kernel.org>
2020-02-20rcutorture: Add 100-CPU configurationPaul E. McKenney
The small-system rcutorture configurations have served us well for a great many years, but it is now time to add a larger one. This commit does just that, but does not add it to the defaults in CFLIST. This allows the kvm.sh argument '--configs "4*CFLIST TREE10" to run four instances of each of the default configurations concurrently with one instance of the large configuration.

2020-02-20torture: Make results-directory date format completion-friendlyPaul E. McKenney
The names of the per-test results directories are of the form 2019.11.29-20:42:19. This works, but the ":" characters make tab-based shell name completion a bit onerous because the user must remember to include a quote character somewhere before the first ":". This commit therefore changes the ":" characters to periods, as in 2019.12.01-20.48.01", which allows tab-based completion to work more naturally. Signed-off-by: Paul E. McKenney <paulmck@kernel.org>
2020-02-20locktorture: Allow CPU-hotplug to be disabled via --bootargsPaul E. McKenney
The bootparam_hotplug_cpu() bash function was checking for CPU-hotplug kernel-boot parameters from --bootargs, but that check was specific to rcutorture ("rcutorture\.onoff_"). This commit therefore makes this check also work for locktorture ("torture\.onoff_"). Note that rcuperf does not do CPU-hotplug operations, so it is not necessary to make a similar change for rcuperf. Signed-off-by: Paul E. McKenney <paulmck@kernel.org>

2020-02-20selftests: Install settings files to fix TIMEOUT failuresMichael Ellerman
Commit 852c8cbf34d3 ("selftests/kselftest/runner.sh: Add 45 second timeout per test") added a 45 second timeout for tests, and also added a way for tests to customise the timeout via a settings file. For example the ftrace tests take multiple minutes to run, so they were given longer in commit b43e78f65b1d ("tracing/selftests: Turn off timeout setting"). This works when the tests are run from the source tree. However if the tests are installed with "make -C tools/testing/selftests install", the settings files are not copied into the install directory. When the tests are then run from the install directory the longer timeouts are not applied and the tests timeout incorrectly. So add the settings files to TEST_FILES of the appropriate Makefiles to cause the settings files to be installed using the existing install logic.

2020-02-19selftests/bpf: Change llvm flag -mcpu=probe to -mcpu=v3Yonghong Song
The latest llvm supports cpu version v3, which is cpu version v1 plus some additional 64bit jmp insns and 32bit jmp insn support. In selftests/bpf Makefile, the llvm flag -mcpu=probe did runtime probe into the host system. Depending on compilation environments, it is possible that runtime probe may fail, e.g., due to memlock issue. This will cause generated code with cpu version v1. This may cause confusion as the same compiler and the same C code generates different byte codes in different environment.

2020-02-19selftests/bpf: Test unhashing kTLS socket after removing from mapJakub Sitnicki
When a TCP socket gets inserted into a sockmap, its sk_prot callbacks get replaced with tcp_bpf callbacks built from regular tcp callbacks. If TLS gets enabled on the same socket, sk_prot callbacks get replaced once again, this time with kTLS callbacks built from tcp_bpf callbacks. Now, we allow removing a socket from a sockmap that has kTLS enabled. After removal, socket remains with kTLS configured. This is where things things get tricky. Since the socket has a set of sk_prot callbacks that are a mix of kTLS and tcp_bpf callbacks, we need to restore just the tcp_bpf callbacks to the original ones. At the moment, it comes down to the the unhash operation. We had a regression recently because tcp_bpf callbacks were not cleared in this particular scenario of removing a kTLS socket from a sockmap. It got fixed in commit 4da6a196f93b ("bpf: Sockmap/tls, during free we may call tcp_bpf_unhash() in loop"). Add a test that triggers the regression so that we don't reintroduce it in the future.

2020-02-17selftests: mlxsw: Remove deprecated testIdo Schimmel
The addition of a VLAN on a bridge slave prompts the driver to have the local port in question join the FID corresponding to this VLAN. Before recent changes, the operation of joining the FID would also mean that the driver would enable VXLAN tunneling if a VXLAN device was also member in the VLAN. In case the configuration of the VXLAN tunnel was not supported, an extack error would be returned. Since the operation of joining the FID no longer means that VXLAN tunneling is potentially enabled, the test is no longer relevant. Remove it.

2020-02-16tools: testing: vsock: Test when server is bound but not listeningSebastien Boeuf
Whenever the server side of vsock is binding to the socket, but not listening yet, we expect the behavior from the client to be identical to what happens when the server is not even started. This new test runs the server side so that it binds to the socket without ever listening to it. The client side will try to connect and should receive an ECONNRESET error. This new test provides a way to validate the previously introduced patch for making sure the server side will always answer with a RST packet in case the client requested a new connection.

After commit 71130f29979c ("vxlan: fix tos value before xmit") we start strict vxlan xmit tos value by RT_TOS(), which limits the tos value less than 0x1E. With current value 0x40 the test will failed with "v1: Expected to capture 10 packets, got 0". So let's choose a smaller tos value for testing.

2020-02-16ipv6: Fix route replacement with dev-only routeBenjamin Poirier
After commit 27596472473a ("ipv6: fix ECMP route replacement") it is no longer possible to replace an ECMP-able route by a non ECMP-able route. For example, ip route add 2001:db8::1/128 via fe80::1 dev dummy0 ip route replace 2001:db8::1/128 dev dummy0 does not work as expected. Tweak the replacement logic so that point 3 in the log of the above commit becomes: 3. If the new route is not ECMP-able, and no matching non-ECMP-able route exists, replace matching ECMP-able route (if any) or add the new route. We can now summarize the entire replace semantics to: When doing a replace, prefer replacing a matching route of the same "ECMP-able-ness" as the replace argument. If there is no such candidate, fallback to the first route found.

2020-02-16selftests: forwarding: use proto icmp for {gretap, ip6gretap}_mac testingHangbin Liu
For tc ip_proto filter, when we extract the flow via __skb_flow_dissect() without flag FLOW_DISSECTOR_F_STOP_AT_ENCAP, we will continue extract to the inner proto. So for GRE + ICMP messages, we should not track GRE proto, but inner ICMP proto. For test mirror_gre.sh, it may make user confused if we capture ICMP message on $h3(since the flow is GRE message). So I move the capture dev to h3-gt{4,6}, and only capture ICMP message.
