[PATCH AUTOSEL 5.7 208/274] selftests/bpf: Fix test_align verifier log patterns

[PATCH AUTOSEL 5.7 203/274] selftests: fix flower parent qdisc

by Sasha Levin

From: Vlad Buslov <vladbu(a)mellanox.com> [ Upstream commit 0531b0357ba37464e5c0033e1b7c69bbf5ecd8fb ] Flower tests used to create ingress filter with specified parent qdisc "parent ffff:" but dump them on "ingress". With recent commit that fixed tcm_parent handling in dump those are not considered same parent anymore, which causes iproute2 tc to emit additional "parent ffff:" in first line of filter dump output. The change in output causes filter match in tests to fail. Prevent parent qdisc output when dumping filters in flower tests by always correctly specifying "ingress" parent both when creating and dumping filters.

[PATCH AUTOSEL 5.6 119/606] selftests: fix kvm relocatable native/cross builds and installs

by Sasha Levin

From: Shuah Khan <skhan(a)linuxfoundation.org> [ Upstream commit 66d69e081b526b6a6031f0d3ca8ddff71e5707a5 ] kvm test Makefile doesn't fully support cross-builds and installs. UNAME_M = $(shell uname -m) variable is used to define the target programs and libraries to be built from arch specific sources in sub-directories. For cross-builds to work, UNAME_M has to map to ARCH and arch specific directories and targets in this Makefile. UNAME_M variable to used to run the compiles pointing to the right arch directories and build the right targets for these supported architectures. TEST_GEN_PROGS and LIBKVM are set using UNAME_M variable. LINUX_TOOL_ARCH_INCLUDE is set using ARCH variable. x86_64 targets are named to include x86_64 as a suffix and directories for includes are in x86_64 sub-directory. s390x and aarch64 follow the same convention. "uname -m" doesn't result in the correct mapping for s390x and aarch64. Fix it to set UNAME_M correctly for s390x and aarch64 cross-builds. In addition, Makefile doesn't create arch sub-directories in the case of relocatable builds and test programs under s390x and x86_64 directories fail to build. This is a problem for native and cross-builds. Fix it to create all necessary directories keying off of TEST_GEN_PROGS. The following use-cases work with this change: Native x86_64: make O=/tmp/kselftest -C tools/testing/selftests TARGETS=kvm install \ INSTALL_PATH=$HOME/x86_64 arm64 cross-build: make O=$HOME/arm64_build/ ARCH=arm64 HOSTCC=gcc \ CROSS_COMPILE=aarch64-linux-gnu- defconfig make O=$HOME/arm64_build/ ARCH=arm64 HOSTCC=gcc \ CROSS_COMPILE=aarch64-linux-gnu- all make kselftest-install TARGETS=kvm O=$HOME/arm64_build ARCH=arm64 \ HOSTCC=gcc CROSS_COMPILE=aarch64-linux-gnu- s390x cross-build: make O=$HOME/s390x_build/ ARCH=s390 HOSTCC=gcc \ CROSS_COMPILE=s390x-linux-gnu- defconfig make O=$HOME/s390x_build/ ARCH=s390 HOSTCC=gcc \ CROSS_COMPILE=s390x-linux-gnu- all make kselftest-install TARGETS=kvm O=$HOME/s390x_build/ ARCH=s390 \ HOSTCC=gcc CROSS_COMPILE=s390x-linux-gnu- all No regressions in the following use-cases: make -C tools/testing/selftests TARGETS=kvm make kselftest-all TARGETS=kvm Signed-off-by: Shuah Khan <skhan(a)linuxfoundation.org> Signed-off-by: Sasha Levin <sashal(a)kernel.org> --- tools/testing/selftests/kvm/Makefile | 29 +++++++++++++++++++++++++++- 1 file changed, 28 insertions(+), 1 deletion(-) diff --git a/tools/testing/selftests/kvm/Makefile b/tools/testing/selftests/kvm/Makefile index d91c53b726e6..75dec268787f 100644 --- a/tools/testing/selftests/kvm/Makefile +++ b/tools/testing/selftests/kvm/Makefile @@ -5,8 +5,34 @@ all: top_srcdir = ../../../..

[PATCH AUTOSEL 5.6 118/606] ftrace/selftest: make unresolved cases cause failure if --fail-unresolved set

by Sasha Levin

From: Alan Maguire <alan.maguire(a)oracle.com> [ Upstream commit b730d668138cb3dd9ce78f8003986d1adae5523a ] Currently, ftracetest will return 1 (failure) if any unresolved cases are encountered. The unresolved status results from modules and programs not being available, and as such does not indicate any issues with ftrace itself. As such, change the behaviour of ftracetest in line with unsupported cases; if unsupported cases happen, ftracetest still returns 0 unless --fail-unsupported. Here --fail-unresolved is added and the default is to return 0 if unresolved results occur.
