https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D231050 Bug ID: 231050 Summary: NFS via IPv6 between 11.2-REL amd64 fails for larger directories Product: Base System Version: 11.2-RELEASE Hardware: Any OS: Any Status: New Severity: Affects Only Me Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: pi@FreeBSD.org NFS via IPv6 between 11.2-REL amd64 boxes failed for directories with more than 45 files or directories. Small directories worked. It seems to be an issue with ipv6 fragmentation (?), as can be seen by tcpdump: 17:54:16.855978 IP6 nfs-serv > nfs-client frag (0|1448) 2049 > 709: NFS reply xid 1536109002 reply ok 1440 readdir 17:54:16.855979 IP6 nfs-serv > nfs-client frag (1448|36) As soon as the NFS request is sent with fragments, it stalls. Using TCP or IPv4 for the nfs mount works, UDP fails. --=20 You are receiving this mail because: You are the assignee for the bug.=
