Subject: [PATCH bpf-next 0/2] Fix test_probe_user on s390x
Date: Sat, 23 Jul 2022 04:03:42 +0200	[thread overview]
Message-ID: <20220723020344.21699-1-iii@linux.ibm.com> (raw)

Hi,

This is a fix for [1]: test_probe_user fails on s390x, because it hooks
only connect(), but not socketcall(SYS_CONNECT).

Patch 1 adds this quirk to BPF_KSYSCALL documentation.
Patch 2 fixes the test by attaching a prog to socketcall().

Best regards,
Ilya
