Cong Wang 311633b604 hsr: switch ->dellink() to ->ndo_uninit() ... Switching from ->priv_destructor to dellink() has an unexpected consequence: existing RCU readers, that is, hsr_port_get_hsr() callers, may still be able to read the port list. Instead of checking the return value of each hsr_port_get_hsr(), we can just move it to ->ndo_uninit() which is called after device unregister and synchronize_net(), and we still have RTNL lock there. Fixes: b9a1e62740 ("hsr: implement dellink to clean up resources") Fixes: edf070a0fb ("hsr: fix a NULL pointer deref in hsr_dev_xmit()") Reported-by: syzbot+097ef84cdc95843fbaa8@syzkaller.appspotmail.com Cc: Arvid Brodin <arvid.brodin@alten.se> Signed-off-by: Cong Wang <xiyou.wangcong@gmail.com> Signed-off-by: David S.
