Summary: SELinux is preventing Samba (/usr/sbin/smbd) "getattr" access to /proc/fs/nfsd. Detailed Description: [SELinux is in permissive mode. This access was not denied.] SELinux denied samba access to /proc/fs/nfsd. If you want to share this directory with samba it has to have a file context label of samba_share_t. If you did not intend to use /proc/fs/nfsd as a samba repository it could indicate either a bug or it could signal a intrusion attempt. Please refer to 'man samba_selinux' for more information on setting up Samba and SELinux. Allowing Access: You can alter the file context by executing chcon -R -t samba_share_t '/proc/fs/nfsd' You must also change the default file context files on the system in order to preserve them even on a full relabel. "semanage fcontext -a -t samba_share_t '/proc/fs/nfsd'" Fix Command: chcon -R -t samba_share_t '/proc/fs/nfsd' Additional Information: Source Context system_u:system_r:smbd_t:s0 Target Context system_u:object_r:nfsd_fs_t:s0 Target Objects /proc/fs/nfsd [ dir ] Source smbd Source Path /usr/sbin/smbd Port <Unknown> Host (removed) Source RPM Packages samba-3.5.0-55rc3.fc14 Target RPM Packages Policy RPM selinux-policy-3.7.15-4.fc13 Selinux Enabled True Policy Type targeted Enforcing Mode Permissive Plugin Name samba_share Host Name (removed) Platform Linux (removed) 2.6.34-0.28.rc3.git3.fc14.i686.PAE #1 SMP Mon Apr 5 17:05:06 UTC 2010 i686 i686 Alert Count 212 First Seen Tue 22 Sep 2009 12:01:22 AM EDT Last Seen Thu 22 Apr 2010 11:09:11 PM EDT Local ID c0da8e20-c649-4c06-b88a-95e0fc21e7f5 Line Numbers Raw Audit Messages node=(removed) type=AVC msg=audit(1271992151.541:25495): avc: denied { getattr } for pid=15330 comm="smbd" path="/proc/fs/nfsd" dev=nfsd ino=1 scontext=system_u:system_r:smbd_t:s0 tcontext=system_u:object_r:nfsd_fs_t:s0 tclass=dir node=(removed) type=SYSCALL msg=audit(1271992151.541:25495): arch=40000003 syscall=195 success=yes exit=0 a0=bf896abd a1=bf896eb8 a2=544ff4 a3=0 items=0 ppid=1652 pid=15330 auid=4294967295 uid=0 gid=0 euid=500 suid=500 fsuid=500 egid=500 sgid=500 fsgid=500 tty=(none) ses=4294967295 comm="smbd" exe="/usr/sbin/smbd" subj=system_u:system_r:smbd_t:s0 key=(null) Hash String generated from samba_share,smbd,smbd_t,nfsd_fs_t,dir,getattr audit2allow suggests: #============= smbd_t ============== allow smbd_t nfsd_fs_t:dir getattr;
