selftests/kselftest/runner.sh: Add 45 second timeout per test

2019-11-06T12:08:03+00:00

[ Upstream commit 852c8cbf34d3b3130a05c38064dd98614f97d3a8 ] Commit a745f7af3cbd ("selftests/harness: Add 30 second timeout per test") solves the problem of kselftest_harness.h-using binary tests possibly hanging forever. However, scripts and other binaries can still hang forever. This adds a global timeout to each test script run. To make this configurable (e.g. as needed in the "rtc" test case), include a new per-test-directory "settings" file (similar to "config") that can contain kselftest-specific settings. The first recognized field is "timeout". Additionally, this splits the reporting for timeouts into a specific "TIMEOUT" not-ok (and adds exit code reporting in the remaining case).

selftests: kvm: Fix libkvm build error

2019-10-29T08:21:43+00:00

[ Upstream commit 6e06983dde969c15eb4fdab77f0eda8b18ea28e6 ] Fix the following build error from "make TARGETS=kvm kselftest": libkvm.a(assert.o): relocation R_X86_64_32 against `.rodata.str1.1' can not be used when making a PIE object; recompile with -fPIC This error is seen when build is done from the main Makefile using kselftest target. In this case KBUILD_CPPFLAGS and CC_OPTION_CFLAGS are defined. When build is invoked using: "make -C tools/testing/selftests/kvm" KBUILD_CPPFLAGS and CC_OPTION_CFLAGS aren't defined. There is no need to pass in KBUILD_CPPFLAGS and CC_OPTION_CFLAGS for the check to determine if --no-pie is necessary, which is the case when these two aren't defined when "make -C tools/testing/selftests/kvm" runs. Fix it by simplifying the no-pie-option logic. With this change, both build variations work.

selftests/bpf: adjust strobemeta loop to satisfy latest clang

2019-10-11T16:36:46+00:00

[ Upstream commit 4670d68b9254710fdeaf794cad54d8b2c9929e0a ] Some recent changes in latest Clang started causing the following warning when unrolling strobemeta test case main loop: progs/strobemeta.h:416:2: warning: loop not unrolled: the optimizer was unable to perform the requested transformation; the transformation might be disabled or specified as part of an unsupported transformation ordering [-Wpass-failed=transform-warning] This patch simplifies loop's exit condition to depend only on constant max iteration number (STROBE_MAX_MAP_ENTRIES), while moving early termination logic inside the loop body. The changes are equivalent from program logic standpoint, but fixes the warning. It also appears to improve generated BPF code, as it fixes previously failing non-unrolled strobemeta test cases.

selftests/seccomp: fix build on older kernels

2019-10-11T16:36:38+00:00

[ Upstream commit 88282297fff00796e81f5e67734a6afdfb31fbc4 ] The seccomp selftest goes to some length to build against older kernel headers, viz. all the #ifdefs at the beginning of the file. Commit 201766a20e30 ("ptrace: add PTRACE_GET_SYSCALL_INFO request") introduces some additional macros, but doesn't do the #ifdef dance. Let's add that dance here to avoid: gcc -Wl,-no-as-needed -Wall seccomp_bpf.c -lpthread -o seccomp_bpf In file included from seccomp_bpf.c:51: seccomp_bpf.c: In function ‘tracer_ptrace’: seccomp_bpf.c:1787:20: error: ‘PTRACE_EVENTMSG_SYSCALL_ENTRY’ undeclared (first use in this function); did you mean ‘PTRACE_EVENT_CLONE’?

udp: only do GSO if # of segs > 1

2019-10-07T17:01:51+00:00

[ Upstream commit 4094871db1d65810acab3d57f6089aa39ef7f648 ] Prior to this change an application sending <= 1MSS worth of data and enabling UDP GSO would fail if the system had SW GSO enabled, but the same send would succeed if HW GSO offload is enabled. In addition to this inconsistency the error in the SW GSO case does not get back to the application if sending out of a real device so the user is unaware of this failure. With this change we only perform GSO if the # of segments is > 1 even if the application has enabled segmentation. I've also updated the relevant udpgso selftests.
