Description of problem: rpc.mountd does work correctly, hence effectively disabling NFS mounts from FC2-t2 NFS server. Version-Release number of selected component (if applicable): nfs-utils-1.0.6-19.fc2 How reproducible: Always in my configuration, both with 2.6.3-2.1.253.2.1 and 2.6.5 custom kernel. Steps to Reproduce: 1. [root@fmh root]# cat /etc/exports / 127.0.0.1(rw,no_root_squash,sync) / 192.168.0.2(rw,no_root_squash,sync) /teo 192.168.0.2(rw,no_root_squash,sync) /home 192.168.0.2(rw,no_root_squash,sync) /usr/src 192.168.0.2(rw,no_root_squash,sync) 2. [root@fmh root]# service portmap start Starting portmapper: [ OK ] 3. [root@fmh root]# S=start; service nfslock $S && service rpcgssd $S && service rpcidmapd $S && service rpcsvcgssd $S && service nfs $S Starting NFS statd: [ OK ] Starting NFS services: [ OK ] Starting NFS daemon: [ OK ] Starting NFS mountd: [ OK ] 4. [root@fmh root]# mount -t nfs 127.0.0.1:/home /tmp/nfsmnt/ mount: 127.0.0.1:/home failed, reason given by server: Permission denied 5. [root@fmh root]# killall rpc.mountd 6. [root@fmh root]# /var/tmp/nfs-utils-root/usr/sbin/rpc.mountd 7. [root@fmh root]# mount -t nfs 127.0.0.1:/home /tmp/nfsmnt/ 8. [root@fmh root]# ls -la /tmp/nfsmnt/ total 16 drwxr-xr-x 4 root root 4096 Mar 12 05:33 . drwxrwxrwt 7 root root 4096 May 11 06:19 .. drwx------ 48 farco farco 4096 May 11 06:15 farco drwx------ 10 vit vit 4096 Apr 18 09:29 vit Actual results: mount: 127.0.0.1:/home failed, reason given by server: Permission denied Expected results: mount succeeds Additional info: mountd started in 6th step is newly compiled nfs-utils-1.0.6 (rpmbuild -bi nfs-utils.spec) from nfs.sf.net. The problem seems to lie in RH patches to mountd and its libraries, namely the /proc/ file interface is probably not used in correct way. I have no chance to test FC2t3 now but the problem may persist as it was not reported before.
