[PATCH] selftests/net: enable fragments for fib-onlink-tests

by Anders Roxell

We miss CONFIG_* fragments so test fib-onlink-tests.sh can do: ip li add lisa type vrf table 1101 ip li add veth1 type veth peer name veth2 And the follow message occurs if it isn't enabled: Configuring interfaces RTNETLINK answers: Operation not supported This enables for NET_NRF (and friends) and VETH so we can create a vrf table and veth.

[PATCH] selftests/size: rework to use main instead of _start

by Anders Roxell

In a -ffreestanding environment without glibc, we shouldn't be able to call either getenv or printf. It seems that printf() happens to work fine, but it ends up using the glibc getenv(), which doesn't work unless we call the glibc _start() function first. Using _start() was originally meant as an optimization to reduce the memory consumption of the test program itself, in order to get a more accurate representation of the available RAM at system boot time. However, it causes more problems than it helps, especially when run from a shell script that also consumes some memory. get_size[2838]: segfault at ffffffffffffffd0 ip 000000000040538b sp 00007ffc41980668 error 5 in get_size[400000+b0000] audit: type=1701 audit(1521532923.838:4): auid=0 uid=0 gid=0 ses=2 subj=kernel pid=2838 comm=\"get_size\" exe=\"/opt/kselftests/next/size/get_size\" sig=11 res=1 get_size[2840]: segfault at ffffffffffffffd0 ip 000000000040538b sp 00007ffdace9b378 error 5 in get_size[400000+b0000] audit: type=1701 audit(1521532932.057:5): auid=0 uid=0 gid=0 ses=2 subj=kernel pid=2840 comm=\"get_size\" exe=\"/opt/kselftests/next/size/get_size\" sig=11 res=1 Rework to get_size test to use main (and printf) instead of _start.

[PATCH v2] selftests: futex Makefile add top level TAP header echo to RUN_TESTS

Add top level TAP header echo, testname and separator line to make the output consistent with the common run_tests target. This change prevents nested TAP13 headers output from individual tests. Nested TAP13 headers could cause problems for some parsers.

[PATCH 0/5] Handling for TAP header level

by Shuah Khan

This patch series is a result discussion with Tim Bird about nested TAP header handling. Based on the discussion, I am introducing a environment variable to prevent nested TAP headers. These patches improve the run_tests output and the output from the script generated by emit_tests. This first patch in this series adds environment variable KSFT_TAP_LEVEL to avoid printing nested TAP headers for each test. lib.mk run_tests target prints TAP header before invoking the test program or test script. Tests need a way to suppress TAP headers if it is already printed out. This new environment variable adds a way for ksft_print_header() print TAP header only when KSFT_TAP_LEVEL isn't set. The second patch in this series changes lib.mk run_tests target to set KSFT_TAP_LEVEL before running tests. The third patch changes Makefile to export KSFT_TAP_LEVEL and adds TAP and KSFT_TAP_LEVEL handling to emit_tests target. Forth and fifth patches make changes to size and futex tests to prevent nested TAP headers to take advantage of the framework change in the first patch. Shuah Khan (5): selftests: kselftest framework: add handling for TAP header level selftests: lib.mk set KSFT_TAP_LEVEL to prevent nested TAP headers selftests: Makefile set KSFT_TAP_LEVEL to prevent nested TAP headers selftests: size call ksft_print_header() to print TAP header selftests: futex Makefile add top level TAP header echo to RUN_TESTS tools/testing/selftests/Makefile | 10 +++++++++- tools/testing/selftests/futex/Makefile | 3 +++ tools/testing/selftests/kselftest.h | 3 ++- tools/testing/selftests/lib.mk | 1 + tools/testing/selftests/size/get_size.c | 4 +++- 5 files changed, 18 insertions(+), 3 deletions(-) -- 2.14.1 -- To unsubscribe from this list: send the line "unsubscribe linux-kselftest" in the body of a message to majordomo(a)vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

[PATCH v4 00/19] tracing: probeevent: Improve fetcharg features

by Masami Hiramatsu

Hi, This is the 4th version of the fetch-arg improvement series. This includes variable changes on fetcharg framework like, - Add fetcharg testcases (syntax, argN, symbol, string and array) and probepoint testcase. - Rewrite fetcharg framework with fetch_insn, switch-case based instead of function pointer. - Add "symbol" type support, which shows symbol+offset instead of address value. - Add "$argN" fetcharg, which fetches function parameters. (currently only for x86-64) - Add array type support (including string arrary :) ) , which enables to get fixed length array from probe-events. V3 is here: https://lkml.org/lkml/2018/2/24/3 Changes from the v3 are here: - [1/19] Fix to pass a sign to kstrtol (Thanks Namhyung!) and check UINT_MAX for kprobe's offset. - [4/19] Add new testcase for checking probepoint syntax. - [16/19] Fix to use calculated size correctly for field definition. (Thank you Namhyung!). - [19/19] Add format field tests.
