2020-11-04selftests: net: bridge: factor out and rename sg state functionsNikolay Aleksandrov2-123/+123
Factor out S,G entry state checking functions for existence, forwarding, blocking and timer to lib.sh so they can be later used by MLDv2 tests. Add brmcast_ suffix to their name to make the relation to the bridge explicit. Signed-off-by: Nikolay Aleksandrov <[email protected]> Signed-off-by: Jakub Kicinski <[email protected]>

In order to test an IPv6 multicast packet we need to pass different tc and mausezahn protocols only, so add a simple check for the destination address which decides if we should generate an IPv4 or IPv6 mcast packet.

2020-11-03selftest/bpf: Use global variables instead of maps for test_tcpbpf_kernAlexander Duyck3-108/+31
Use global variables instead of global_map and sockopt_results_map to track test data. Doing this greatly simplifies the code as there is not need to take the extra steps of updating the maps or looking up elements.

2020-11-03selftests/bpf: Migrate tcpbpf_user.c to use BPF skeletonAlexander Duyck1-27/+14
Update tcpbpf_user.c to make use of the BPF skeleton. Doing this we can simplify test_tcpbpf_user and reduce the overhead involved in setting up the test. In addition we can clean up the remaining bits such as the one remaining CHECK_FAIL at the end of test_tcpbpf_user so that the function only makes use of CHECK as needed.

2020-11-03selftests/bpf: Replace EXPECT_EQ with ASSERT_EQ and refactor verify_resultsAlexander Duyck1-72/+43
There is already logic in test_progs.h for asserting that a value is expected to be another value. So instead of reinventing it we should just make use of ASSERT_EQ in tcpbpf_user.c. This will allow for better debugging and integrates much more closely with the test_progs framework. In addition we can refactor the code a bit to merge together the two verify functions and tie them together into a single function. Doing this helps to clean the code up a bit and makes it more readable as all the verification is now done in one function. Lastly we can relocate the verification to the end of the run_test since it is logically part of the test itself. With this we can drop the need for a return value from run_test since verification becomes the last step of the call and then immediately following is the tear down of the test setup.

2020-11-03selftests/bpf: Drop python client/server in favor of threadsAlexander Duyck3-147/+78
Drop the tcp_client/server.py files in favor of using a client and server thread within the test case. Specifically we spawn a new thread to play the role of the server, and the main testing thread plays the role of client. Add logic to the end of the run_test function to guarantee that the sockets are closed when we begin verifying results. Doing this we are able to reduce overhead since we don't have two python workers possibly floating around. In addition we don't have to worry about synchronization issues and as such the retry loop waiting for the threads to close the sockets can be dropped as we will have already closed the sockets in the local executable and synchronized the server thread.

2020-11-03selftests/bpf: Move test_tcppbf_user into test_progsAlexander Duyck3-36/+10
Recently a bug was missed due to the fact that test_tcpbpf_user is not a part of test_progs. In order to prevent similar issues in the future move the test functionality into test_progs. By doing this we can make certain that it is a part of standard testing and will not be overlooked. As a part of moving the functionality into test_progs it is necessary to integrate with the test_progs framework and to drop any redundant code. This patch: 1. Cleans up the include headers 2. Dropped a duplicate definition of bpf_find_map 3. Switched over to using test_progs specific cgroup functions 4. Renamed main to test_tcpbpf_user 5. Dropped return value in favor of CHECK_FAIL to check for errors The general idea is that I wanted to keep the changes as small as possible while moving the file into the test_progs framework. The follow-on patches are meant to clean up the remaining issues such as the use of CHECK_FAIL.

2020-11-02torture: Don't kill gdb sessionsPaul E. McKenney1-1/+4
The rcutorture scripting will do a "kill -9" on any guest OS that exceeds its --duration by more than a few minutes, which is very valuable when bugs result in hangs. However, this is a problem when the "hang" was due to a --gdb debugging session. This commit therefore refrains from killing the guest OS when a debugging session is in progress. This means that the user must manually kill the kvm.sh process group if a hang really does occur. Signed-off-by: Paul E. McKenney <[email protected]>
2020-11-02rcutorture: Make preemptible TRACE02 enable lockdepPaul E. McKenney2-6/+6
Currently, the CONFIG_PREEMPT_NONE=y rcutorture TRACE01 rcutorture scenario enables lockdep. This limits its ability to find bugs due to non-preemptible sections of code being RCU readers, and pretty much all code thus appearing to lockdep to be an RCU reader. This commit therefore moves lockdep testing to the CONFIG_PREEMPT=y rcutorture TRACE02 scenario. Signed-off-by: Paul E. McKenney <[email protected]>

2020-11-02drm: Remove SCATTERLIST_MAX_SEGMENTJason Gunthorpe1-1/+1
Since commit 9a40401cfa13 ("lib/scatterlist: Do not limit max_segment to PAGE_ALIGNED values") the max_segment input to sg_alloc_table_from_pages() does not have to be any special value. The new algorithm will always create something less than what the user provides. Thus eliminate this confusing constant. - vmwgfx should use the HW capability, not mix in the OS page size for calling dma_set_max_seg_size() - i915 uses i915_sg_segment_size() both for sg_alloc_table_from_pages and for some open coded sgl construction. This doesn't change the value since rounddown(size, UINT_MAX) == SCATTERLIST_MAX_SEGMENT - drm_prime_pages_to_sg uses it as a default if max_segment is zero, UINT_MAX is fine to use directly.

2020-10-27kselftest: Extend vdso correctness test to clock_gettime64Vincenzo Frascino2-4/+115
With the release of Linux 5.1 has been added a new syscall, clock_gettime64, that provided a 64 bit time value for a specified clock_ID to make the kernel Y2038 safe on 32 bit architectures. Extend the vdso correctness test to cover the newly exposed vdso function.

2020-10-27kselftest: Extend vDSO selftest to clock_getresVincenzo Frascino2-0/+126
The current version of the multiarch vDSO selftest verifies only gettimeofday. Extend the vDSO selftest to clock_getres, to verify that the syscall and the vDSO library function return the same information. The extension has been used to verify the hrtimer_resoltion fix.

2020-10-27kselftest: Extend vDSO selftestVincenzo Frascino3-0/+336
The current version of the multiarch vDSO selftest verifies only gettimeofday. Extend the vDSO selftest to the other library functions: - time - clock_getres - clock_gettime The extension has been used to verify the unified vdso library on the supported architectures.
