2019-04-25selftests: Add plan line and fix result line syntaxKees Cook2-6/+8
The TAP version 13 spec requires a "plan" line, which has been missing. Since we always know how many tests we're going to run, emit the count on the plan line. This also fixes the result lines to remove the "1.." prefix which is against spec, and to mark skips with the correct "# SKIP" suffix.

2019-04-25selftests: Extract logic for multiple test runsKees Cook3-24/+32
This moves the logic for running multiple tests into a single "run_many" function of runner.sh. Both "run_tests" and "emit_tests" are modified to use it. Summary handling is now controlled by the "per_test_logging" shell flag. Signed-off-by: Kees Cook <keescook@chromium.org> Signed-off-by: Shuah Khan <skhan@linuxfoundation.org>

2019-04-25selftests: Extract single-test shell logic from lib.mkKees Cook3-31/+39
In order to improve the reusability of the kselftest test running logic, this extracts the single-test logic from lib.mk into kselftest/runner.sh which lib.mk can call directly. No changes in output. As part of the change, this moves the "summary" Makefile logic around to set a new "logfile" output. This will be used again in the future "emit_tests" target as well.

2019-04-24selftests/bpf: expand test_tc_tunnel with SIT encapWillem de Bruijn3-5/+80
So far, all BPF tc tunnel testcases encapsulate in the same network protocol. Add an encap testcase that requires updating skb->protocol. The 6in4 tunnel encapsulates an IPv6 packet inside an IPv4 tunnel. Verify that bpf_skb_net_grow correctly updates skb->protocol to select the right protocol handler in __netif_receive_skb_core.

2019-04-22selftests: build and run gpio when output directory is the src dirShuah Khan1-0/+9
Build and run gpio when output directory is the src dir. gpio has dependency on tools/gpio and builds tools/gpio objects in the src directory in all cases making the src repo dirty even when object relocation is specified. This fixes the following commands from generating gpio objects in the source repository: make O=dir kselftest export KBUILD_OUTPUT=dir; make kselftest make O=dir -C tools/testing/selftests expoert KBUILD_OUTPUT=dir; make -C tools/testing/selftests The following commands still build gpio objects in the source repo (gpio Makefile needs to fixed): make O=dir kselftest TARGETS="gpio" export KBUILD_OUTPUT=dir; make kselftest TARGETS="gpio" make O=dir -C tools/testing/selftests TARGETS="gpio" expoert KBUILD_OUTPUT=dir; make -C tools/testing/selftests TARGETS="gpio" Signed-off-by: Shuah Khan <skhan@linuxfoundation.org>
2019-04-22tools/testing/nvdimm: add watermarks for dax_pmem* modulesVishal Verma6-0/+33
Add nfit_test 'watermarks' for the dax_pmem, dax_pmem_core, and dax_pmem_compat modules. This causes the nfit_test module to fail loading in case any of these modules are also not overridden with the ldconfig wrapped modules. Without this, nfit_test would sometimes fail creation of device-dax namespaces on the nfit_test_bus with an unhelpful error log such as: dax_pmem dax5.0: could not reserve metadata dax_pmem: probe of dax5.0 failed with error -16 Which was caused due to the unwrapped version of devm_request_mem_region() being called.

2019-04-22media: selftests: media_dev_allocator api testShuah Khan1-0/+85
Add a new test for Media Device Allocator API. Media Device Allocator API to allows multiple drivers share a media device. This API solves a very common use-case for media devices where one physical device (an USB stick) provides both audio and video. When such media device exposes a standard USB Audio class, a proprietary Video class, two or more independent drivers will share a single physical USB bridge. In such cases, it is necessary to coordinate access to the shared resource. Using this API, drivers can allocate a media device with the shared struct device as the key. Once the media device is allocated by a driver, other drivers can get a reference to it. The media device is released when all the references are released. This test does a series of unbind/bind tests to make sure media device is released correctly when it is no longer is use and when the last driver releases the reference.

2019-04-19selftests: fix headers_install circular dependencyShuah Khan2-10/+80
"make kselftest" fails with "Circular Makefile.o <- prepare dependency dropped." error, when lib.mk invokes "make headers_install". Make level 0: Main make calls selftests run_tests target ... Make level n: selftests lib.mk invokes main make's headers_install The secondary level make inherits builtin-rules which will use the rule to generate Makefile.o and runs into "Circular Makefile.o <- prepare dependency dropped." error, and kselftest compile fails. Invoke headers_install target with --no-builtin-rules to avoid circular error.

2019-04-17ktest: Add support for meta characters in GRUB_MENUMasayoshi Mizuma1-2/+4
ktest fails if meta characters are in GRUB_MENU, for example GRUB_MENU = 'Fedora (test)' The failure happens because the meta characters are not escaped, so the menu doesn't match in any entries in GRUB_FILE. Use quotemeta() to escape the meta characters.

If a test has an error, display not only the what type of test failed, but if the test was giving a name, display that too, as well as the current iteration of the tests. Each test has an iteration number associated to it. For error messages display that iteration number along with the test type and test name. This includes the message that gets sent via email.

2019-04-17selftests/kexec: update get_secureboot_modeMimi Zohar1-20/+66
The get_secureboot_mode() function unnecessarily requires both CONFIG_EFIVAR_FS and CONFIG_EFI_VARS to be enabled to determine if the system is booted in secure boot mode. On some systems the old EFI variable support is not enabled or, possibly, even implemented. This patch first checks the efivars filesystem for the SecureBoot and SetupMode flags, but falls back to using the old EFI variable support. The "secure_boot_file" and "setup_mode_file" couldn't be quoted due to globbing. This patch also removes the globbing.

This changes the getpid filter to getppid, and makes sure ASSERTs execute to stop from spawning the listener.

2019-04-16selftests: kvm: add a selftest for SMMVitaly Kuznetsov4-6/+191
Add a simple test for SMM, based on VMX. The test implements its own sync between the guest and the host as using our ucall library seems to be too cumbersome: SMI handler is happening in real-address mode. This patch also fixes KVM_SET_NESTED_STATE to happen after KVM_SET_VCPU_EVENTS, in fact it places it last. This is because KVM needs to know whether the processor is in SMM or not.
