[PATCH bpf-next v2] selftests/bpf: fix incorrect fcntl call (test_sockmap.c)

by Qiao Ma

In test_sockmap.c, the testcase sets socket nonblock first, and then calls select() and recvmsg() to receive data. If some error occur, nonblock setting will make recvmsg() return immediately, rather than blocking forever. However, the way to call fcntl() to set nonblock is wrong. To set socket noblock, we need to use > fcntl(fd, F_SETFL, O_NONBLOCK); rather than: > fcntl(fd, O_NONBLOCK); Signed-off-by: Qiao Ma <mqaio(a)linux.alibaba.com> --- tools/testing/selftests/bpf/test_sockmap.c | 7 ++++++- 1 file changed, 6 insertions(+), 1 deletion(-) diff --git a/tools/testing/selftests/bpf/test_sockmap.c b/tools/testing/selftests/bpf/test_sockmap.c index 0fbaccdc8861..abb4102f33b0 100644 --- a/tools/testing/selftests/bpf/test_sockmap.c +++ b/tools/testing/selftests/bpf/test_sockmap.c @@ -598,7 +598,12 @@ static int msg_loop(int fd, int iov_count, int iov_length, int cnt, struct timeval timeout; fd_set w; - fcntl(fd, fd_flags); + err = fcntl(fd, F_SETFL, fd_flags); + if (err < 0) { + perror("fcntl failed"); + goto out_errno; + } + /* Account for pop bytes noting each iteration of apply will * call msg_pop_data helper so we need to account for this * by calculating the number of apply iterations.

[PATCH v6 1/2] selftests: vm: bring common functions to a new file

[PATCH v1] selftests/landlock: Fix out-of-tree builds

by Mickaël Salaün

These changes simplify the Makefile and handle these 5 ways to build Landlock tests: - make -C tools/testing/selftests/landlock - make -C tools/testing/selftests TARGETS=landlock gen_tar - make TARGETS=landlock kselftest-gen_tar - make TARGETS=landlock O=build kselftest-gen_tar - make -C /tmp/linux TARGETS=landlock O=/tmp/build kselftest-gen_tar This also makes $(KHDR_INCLUDES) available to other test collections when building in their directory.

[PATCH net-next] selftests/bonding: re-add lladdr target test

by Matthieu Baerts

It looks like this test has been accidentally dropped when resolving conflicts in this Makefile. Most probably because there were 3 different patches modifying this file in parallel: commit 152e8ec77640 ("selftests/bonding: add a test for bonding lladdr target") commit bbb774d921e2 ("net: Add tests for bonding and team address list management") commit 2ffd57327ff1 ("selftests: bonding: cause oops in bond_rr_gen_slave_id") The first one was applied in 'net-next' while the two other ones were recently applied in the 'net' tree. But that's alright, easy to fix by re-adding the missing one!

[PATCH] selftests/livepatch: normalize sysctl error message

by Joe Lawrence

The livepatch kselftests rely on comparing expected and actual output from such commands as sysctl. A recent commit in procps-ng v4.0.0 [1] changed sysctl's output to emit key pathnames like: sysctl: setting key "/proc/sys/kernel/ftrace_enabled": Device or resource busy versus previous dotted output: sysctl: setting key "kernel.ftrace_enabled": Device or resource busy The modification in output was later reverted [2], but since the change has been tagged in procps-ng v4.0.0, update the livepatch kselftest to handle either case. [1] https://gitlab.com/procps-ng/procps/-/commit/6389deca5bf667f5fab5912acde78b… [2] https://gitlab.com/procps-ng/procps/-/commit/b159c198c9160a8eb13254e2b631d0… Reported-by: Dennis(Zhuoheng) Li <denli(a)redhat.com> Signed-off-by: Joe Lawrence <joe.lawrence(a)redhat.com> --- tools/testing/selftests/livepatch/functions.sh | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/tools/testing/selftests/livepatch/functions.sh b/tools/testing/selftests/livepatch/functions.sh index 9230b869371d..d5001c9eb72e 100644 --- a/tools/testing/selftests/livepatch/functions.sh +++ b/tools/testing/selftests/livepatch/functions.sh @@ -86,7 +86,7 @@ function set_ftrace_enabled() { if [[ "$result" != "$1" ]] ; then if [[ $can_fail -eq 1 ]] ; then - echo "livepatch: $err" > /dev/kmsg + echo "livepatch: $err" | sed 's#/proc/sys/kernel/#kernel.#' > /dev/kmsg return fi -- 2.26.3
