Hello, the latest current kernel seems to have a broken NFS : it can't get a listing for a shared directory (itself hosted on a just recompiled 6-STABLE server) : # ls /files2/net<TAB>nfs server tfh:/files2: not responding -cvs A pcap trace of the NFS messages is : http://thierry.herbelot.free.fr/nfs-broken/nfs-broken.pcap tfh# tcpdump -n -t -r nfs-broken.pcap reading from file nfs-broken.pcap, link-type EN10MB (Ethernet) IP 192.168.2.12.855699310 > 192.168.2.1.2049: 104 access fh 1056,330756/2 003f IP 192.168.2.1.2049 > 192.168.2.12.855699310: reply ok 120 access c 003f IP 192.168.2.12.855699311 > 192.168.2.1.2049: 104 access fh 1056,330756/2 003f IP 192.168.2.1.2049 > 192.168.2.12.855699311: reply ok 120 access c 003f IP 192.168.2.12.855699312 > 192.168.2.1.2049: 100 fsstat fh 1056,330756/2 IP 192.168.2.1.2049 > 192.168.2.12.855699312: reply ok 168 fsstat tbytes 161358067712 fbytes 9270075392 abytes 2815754240 IP 192.168.2.12.855699313 > 192.168.2.1.2049: 104 access fh 1056,330756/10633216 003f IP 192.168.2.1.2049 > 192.168.2.12.855699313: reply ok 120 access c 003f IP 192.168.2.12.855699314 > 192.168.2.1.2049: 104 access fh 1056,330756/2 003f IP 192.168.2.1.2049 > 192.168.2.12.855699314: reply ok 120 access c 003f IP 192.168.2.12.855699315 > 192.168.2.1.2049: 104 access fh 1056,330756/2 003f IP 192.168.2.1.2049 > 192.168.2.12.855699315: reply ok 120 access c 003f IP 192.168.2.12.855699316 > 192.168.2.1.2049: 100 fsstat fh 1056,330756/2 IP 192.168.2.1.2049 > 192.168.2.12.855699316: reply ok 168 fsstat tbytes 161358067712 fbytes 9270075392 abytes 2815754240 IP 192.168.2.12.855699317 > 192.168.2.1.2049: 112 lookup fh 1056,330756/2 "net-cvs" IP 192.168.2.1.2049 > 192.168.2.12.855699317: reply ok 236 lookup fh 1056,330756/18202624 IP 192.168.2.12.855699317 > 192.168.2.1.2049: 112 lookup fh 1056,330756/2 "net-cvs" IP 192.168.2.1.2049 > 192.168.2.12.855699317: reply ok 236 lookup fh 1056,330756/18202624 IP 192.168.2.12.855699317 > 192.168.2.1.2049: 112 lookup fh 1056,330756/2 "net-cvs" IP 192.168.2.1.2049 > 192.168.2.12.855699317: reply ok 236 lookup fh 1056,330756/18202624 IP 192.168.2.12.855699317 > 192.168.2.1.2049: 112 lookup fh 1056,330756/2 "net-cvs" IP 192.168.2.1.2049 > 192.168.2.12.855699317: reply ok 236 lookup fh 1056,330756/18202624 IP 192.168.2.12.855699317 > 192.168.2.1.2049: 112 lookup fh 1056,330756/2 "net-cvs" IP 192.168.2.1.2049 > 192.168.2.12.855699317: reply ok 236 lookup fh 1056,330756/18202624 IP 192.168.2.12.855699317 > 192.168.2.1.2049: 112 lookup fh 1056,330756/2 "net-cvs" IP 192.168.2.1.2049 > 192.168.2.12.855699317: reply ok 236 lookup fh 1056,330756/18202624 IP 192.168.2.12.855699317 > 192.168.2.1.2049: 112 lookup fh 1056,330756/2 "net-cvs" IP 192.168.2.1.2049 > 192.168.2.12.855699317: reply ok 236 lookup fh 1056,330756/18202624 IP 192.168.2.12.855699317 > 192.168.2.1.2049: 112 lookup fh 1056,330756/2 "net-cvs" IP 192.168.2.1.2049 > 192.168.2.12.855699317: reply ok 236 lookup fh 1056,330756/18202624 IP 192.168.2.12.855699317 > 192.168.2.1.2049: 112 lookup fh 1056,330756/2 "net-cvs" IP 192.168.2.1.2049 > 192.168.2.12.855699317: reply ok 236 lookup fh 1056,330756/18202624 IP 192.168.2.12.855699317 > 192.168.2.1.2049: 112 lookup fh 1056,330756/2 "net-cvs" IP 192.168.2.1.2049 > 192.168.2.12.855699317: reply ok 236 lookup fh 1056,330756/18202624 IP 192.168.2.12.855699317 > 192.168.2.1.2049: 112 lookup fh 1056,330756/2 "net-cvs" IP 192.168.2.1.2049 > 192.168.2.12.855699317: reply ok 236 lookup fh 1056,330756/18202624 the kernel needs 10 tries to read the directory listing ?
