Signed-off-by: Sasha Levin --- Found with a 32-bit build of the selftests with a 64-bit time_t (gcc 16 and clang 21 with -m32 -D_TIME_BITS=64 -D_FILE_OFFSET_BITS=64); KernelCI's 32-bit arm builds show the same warnings. The changed files build without format warnings there now, and the x86_64 builds don't change. The other selftests get the same kind of fix in separate patches. tools/testing/selftests/net/mptcp/pm_nl_ctl.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/tools/testing/selftests/net/mptcp/pm_nl_ctl.c b/tools/testing/selftests/net/mptcp/pm_nl_ctl.c index 78180da1efcc5..36a6d39b31bbf 100644 --- a/tools/testing/selftests/net/mptcp/pm_nl_ctl.c +++ b/tools/testing/selftests/net/mptcp/pm_nl_ctl.c @@ -70,7 +70,7 @@ static int nl_error(struct nlmsghdr *nh) uint32_t off; if (len < sizeof(struct nlmsgerr)) { - error(1, 0, "netlink error message truncated %d min %ld", len, + error(1, 0, "netlink error message truncated %d min %zu", len, sizeof(struct nlmsgerr)); return -1; } -- 2.53.0
