Subject: [PATCH] nfnl_osf: Fix broken conversion to nfnl_query()
|
|
|
|
Due to missing NLM_F_ACK flag in request, nfnetlink code in kernel
|
|
didn't create an own ACK message but left it upon subsystem to ACK or
|
|
not. Since nfnetlink_osf doesn't ACK by itself, nfnl_query() got stuck
|
|
waiting for a reply.
|
|
|
|
Whoever did the conversion from deprecated nfnl_talk() obviously didn't
|
|
even test basic functionality of the tool.
|
|
|
|
Fixes: 52aa15098ebd6 ("nfnl_osf: Replace deprecated nfnl_talk() by nfnl_query()")
