2020-03-21selftests: txtimestamp: add new command-line flags.Jian Yang
A longer sleep duration between sendmsg()s makes more cachelines to be evicted and results in higher latency. Making the duration configurable. Add the following new flags: -S: Configurable sleep duration. -b: Busy loop instead of poll(). Remove the following flag: -D: No delay between packets: subsumed by -S.

2020-03-20kunit: Run all KUnit tests through allyesconfigHeidi Fahim
Implemented the functionality to run all KUnit tests through kunit_tool by specifying an --alltests flag, which builds UML with allyesconfig enabled, and consequently runs every KUnit test. A new function was added to kunit_kernel: make_allyesconfig. Firstly, if --alltests is specified, kunit.py triggers build_um_kernel which call make_allyesconfig. This function calls the make command, disables the broken configs that would otherwise prevent UML from building, then starts the kernel with all possible configurations enabled. All stdout and stderr is sent to test.log and read from there then fed through kunit_parser to parse the tests to the user. Also added a signal_handler in case kunit is interrupted while running. Tested: Run under different conditions such as testing with --raw_output, testing program interrupt then immediately running kunit again without --alltests and making sure to clean the console.

2020-03-20kunit: kunit_parser: make parser more robustHeidi Fahim
Previously, kunit_parser did not properly handle kunit TAP output that - had any prefixes (generated from different configs e.g. CONFIG_PRINTK_TIME) - had unrelated kernel output mixed in the middle of it, which has shown up when testing with allyesconfig To remove prefixes, the parser looks for the first line that includes TAP output, "TAP version 14". It then determines the length of the string before this sequence, and strips that number of characters off the beginning of the following lines until the last KUnit output line is reached. These fixes have been tested with additional tests in the KUnitParseTest and their associated logs have also been added.

2020-03-20selftests/powerpc: Add tm-signal-pagefault testGustavo Luiz Duarte
This test triggers a TM Bad Thing by raising a signal in transactional state and forcing a pagefault to happen in kernelspace when the kernel signal handling code first touches the user signal stack. This is inspired by the test tm-signal-context-force-tm but uses userfaultfd to make the test deterministic. While this test always triggers the bug in one run, I had to execute tm-signal-context-force-tm several times (the test runs 5000 times each execution) to trigger the same bug. tm-signal-context-force-tm is kept instead of replaced because, while this test is more reliable and triggers the same bug, tm-signal-context-force-tm has a better coverage, in the sense that by running the test several times it might trigger the pagefault and/or be preempted at different places. v3: skip test if userfaultfd is unavailable.

2020-03-20selftests/powerpc: Add a test of sigreturn vs VDSOMichael Ellerman
There's two different paths through the sigreturn code, depending on whether the VDSO is mapped or not. We recently discovered a bug in the unmapped case, because it's not commonly used these days. So add a test that sends itself a signal, then moves the VDSO, takes another signal and finally unmaps the VDSO before sending itself another signal. That tests the standard signal path, the code that handles the VDSO being moved, and also the signal path in the case where the VDSO is unmapped.

tracer The ftrace selftest "ftrace - test for function traceon/off triggers" enables all events and reads the trace file. Now that the trace file does not disable tracing, and will attempt to continually read new data that is added, the selftest gets stuck reading the trace file. This is because the data added to the trace file will fill up quicker than the reading of it. By only enabling scheduling events, the read can keep up with the writes. Instead of enabling all events, only enable the scheduler events.

2020-03-18wireguard: noise: error out precomputed DH during handshake rather than configJason A. Donenfeld
We precompute the static-static ECDH during configuration time, in order to save an expensive computation later when receiving network packets. However, not all ECDH computations yield a contributory result. Prior, we were just not letting those peers be added to the interface. However, this creates a strange inconsistency, since it was still possible to add other weird points, like a valid public key plus a low-order point, and, like points that result in zeros, a handshake would not complete. In order to make the behavior more uniform and less surprising, simply allow all peers to be added. Then, we'll error out later when doing the crypto if there's an issue. This also adds more separation between the crypto layer and the configuration layer. Discussed-with: Mathias Hall-Andersen <mathias@hall-andersen.dk> Signed-off-by: Jason A.

Allow to disable gisa 2. protected virtual machines Protected VMs (PVM) are KVM VMs, where KVM can't access the VM's state like guest memory and guest registers anymore. Instead the PVMs are mostly managed by a new entity called Ultravisor (UV), which provides an API, so KVM and the PV can request management actions. PVMs are encrypted at rest and protected from hypervisor access while running. They switch from a normal operation into protected mode, so we can still use the standard boot process to load a encrypted blob and then move it into protected mode. Rebooting is only possible by passing through the unprotected/normal mode and switching to protected again. One mm related patch will go via Andrews mm tree ( mm/gup/writeback: add callbacks for inaccessible pages)
