Subject: [PATCH bpf-next v2] selftests/bpf: Fix endianness issue in sk_assign
Date: Tue, 15 Sep 2020 13:38:15 +0200 [thread overview]
Message-ID: <20200915113815.3768217-1-iii@linux.ibm.com> (raw)
server_map's value size is 8, but the test tries to put an int there.
This sort of works on x86 (unless followed by non-0), but hard fails on
s390.
Fix by using __s64 instead of int.
Fixes: 2d7824ffd25c ("selftests: bpf: Add test for sk_assign")
Signed-off-by: Ilya Leoshkevich <iii@linux.ibm.com>

v1->v2: Use __s64.
