uvm_fault: arp_rtrequest
Status: fixed on 2019/06/14 04:59
Reported-by: syzbot+927e93a362f3ae33dd9c@syzkaller.appspotmail.com
Fix commit: 4cb088386ee5 In arp_rtrequest and nd6_rtrequest return early if the RTF_MPLS flag is set. These mpls routes use the rt_llinfo structure to store the MPLS label and would confuse the arp and nd6 code. OK bluhm@ anton@
