[PATCH AUTOSEL 5.12 068/104] selftests/powerpc: Fix "no_handler" EBB selftest

by Sasha Levin

From: Athira Rajeev <atrajeev(a)linux.vnet.ibm.com> [ Upstream commit 45677c9aebe926192e59475b35a1ff35ff2d4217 ] The "no_handler_test" in ebb selftests attempts to read the PMU registers twice via helper function "dump_ebb_state". First dump is just before closing of event and the second invocation is done after closing of the event. The original intention of second dump_ebb_state was to dump the state of registers at the end of the test when the counters are frozen. But this will be achieved with the first call itself since sample period is set to low value and PMU will be frozen by then. Hence patch removes the dump which was done before closing of the event.

[PATCHv2] selftests: Use kselftest skip code for skipped tests

by Po-Hsu Lin

There are several test cases still using exit 0 when they need to be skipped. Use kselftest framework skip code instead so it can help us to distinguish the proper return status. Criterion to filter out what should be fixed in selftests directory: grep -r "exit 0" -B1 | grep -i skip This change might cause some false-positives if people are running these test scripts directly and only checking their return codes, which will change from 0 to 4. However I think the impact should be small as most of our scripts here are already using this skip code. And there will be no such issue if running them with the kselftest framework. V2: router_mpath_nh.sh and outer_mpath_nh_res.sh sources lib.sh, there is no need to assign ksft_skip value in these two.

[PATCH 0/4] selftests/sgx: Trigger the page reclaimer and #PF handler

by Jarkko Sakkinen

Create a heap for the test enclave, which has the same size as all available Enclave Page Cache (EPC) pages in the system. This will guarantee that all test_encl.elf pages *and* SGX Enclave Control Structure (SECS) have been swapped out by the page reclaimer during the load time. Actually, this adds a bit more stress than that since part of the EPC gets reserved for the Version Array (VA) pages. For each test, the page fault handler gets triggered in two occasions: - When SGX_IOC_ENCLAVE_INIT is performed, SECS gets swapped in by the page fault handler. - During the execution, each page that is referenced gets swapped in by the page fault handler.

[PATCH net-next 0/4] selftests: forwarding: Tests redirects between L3 and L2 devices

by Guillaume Nault

Following merge commit 8eb517a2a4ae ("Merge branch 'reset-mac'"), which made several L3 tunnels reset the skb's mac header pointer after decap, here's a selftest that validates this new behaviour. Patch 1 adds a reusable script for setting up the base network and tests ipip and gre tunnels. The following patches extend the selftest to cover more tunnel types (sit, ip6gre, ip6tnl, vxlan-gpe and bareudp). Guillaume Nault (4): selftests: forwarding: Test redirecting gre or ipip packets to Ethernet selftests: forwarding: Test redirecting sit packets to Ethernet selftests: forwarding: Test redirecting ip6gre and ip6tnl packets to Ethernet selftests: forwarding: Test redirecting vxlan and bareudp packets to Ethernet .../testing/selftests/net/forwarding/Makefile | 1 + tools/testing/selftests/net/forwarding/config | 7 + .../net/forwarding/tc_redirect_l2l3.sh | 438 ++++++++++++++++++ .../net/forwarding/topo_nschain_lib.sh | 267 +++++++++++ 4 files changed, 713 insertions(+) create mode 100755 tools/testing/selftests/net/forwarding/tc_redirect_l2l3.sh create mode 100644 tools/testing/selftests/net/forwarding/topo_nschain_lib.sh -- 2.21.3

KUnit Hackathon

by André Almeida

Hello, We belong to two student groups, FLUSP [1] and LKCAMP [2], both of which are focused on sharing kernel and free software development knowledge and experience with fellow free software developers and newcomers. As part of our efforts, we'll be organizing a KUnit hackathon in the next Saturday (July 10), where we intend to help newcomers convert existing runtime tests (the ones found at lib/) to KUnit and maybe create new ones. Depending on the number of attendees, a high volume of patches may be sent throughout the day. We will do our best to review all patches before they go to the kernel mailing lists hoping to avoid wasting your time with minor patching issues. So we wanted to let you know of all this beforehand and give you the time to send any suggestions or comments on all this. For instance, we may ask people to add a special tag to their patches so you may batch review them all at a later time if you wish. Anyhow, we'd really appreciate having your opinion on this. Thanks!
