Revision 32818c075c54bb0cae44dd6f7ab00b01c52b8372 authored by Cong Wang on 23 July 2020, 01:56:25 UTC, committed by David S. Miller on 23 July 2020, 22:19:58 UTC
geneve_nl2info() sets 'df' conditionally, so we have to initialize it by copying the value from existing geneve device in geneve_changelink(). Fixes: 56c09de347e4 ("geneve: allow changing DF behavior after creation") Reported-by: syzbot+7ebc2e088af5e4c0c9fa@syzkaller.appspotmail.com Cc: Sabrina Dubroca <sd@queasysnail.net> Signed-off-by: Cong Wang <xiyou.wangcong@gmail.com> Reviewed-by: Sabrina Dubroca <sd@queasysnail.net> Signed-off-by: David S.
