Description of problem: I have a win7 virtual machine. In order to communicate with my fedora 20 host, I decided to setup a samba server and have win7 mount my fedora 20 box. Setting up samba was easy. I even followed the selinux suggestion in /etc/samba/smb.conf setsebool -P samba_export_all_rw on However, every time my win7 box creates a new directory (or renames or deletes) inside the samba shared folder, selinux throws out these errors. I thought the whole point of telling selinux to 'export all rw' was to allow the top level directory and everyone below it to be 'selinux friendly'. I am hoping I don't have to explicitly give permission for every single directory created below the top level share directory. That would be very frustrating. SELinux is preventing /usr/sbin/smbd from 'setattr' accesses on the directory Shared. ***** Plugin samba_share (89.9 confidence) suggests *********************** If you want to allow smbd to have setattr access on the Shared directory Then you need to change the label on 'Shared' Do # semanage fcontext -a -t samba_share_t 'Shared' # restorecon -v 'Shared' ***** Plugin catchall_labels (9.27 confidence) suggests ******************* If you want to allow smbd to have setattr access on the Shared directory Then you need to change the label on Shared Do # semanage fcontext -a -t FILE_TYPE 'Shared' where FILE_TYPE is one of the following: auth_cache_t, samba_log_t, samba_share_t, samba_var_t, smbd_tmp_t, smbd_tmpfs_t, smbd_var_run_t. Then execute: restorecon -v 'Shared' ***** Plugin catchall (2.25 confidence) suggests ************************** If you believe that smbd should be allowed setattr access on the Shared directory by default. Then you should report this as a bug. You can generate a local policy module to allow this access. Do allow this access for now by executing: # grep smbd /var/log/audit/audit.log | audit2allow -M mypol # semodule -i mypol.pp Additional Information: Source Context system_u:system_r:smbd_t:s0 Target Context system_u:object_r:default_t:s0 Target Objects Shared [ dir ] Source smbd Source Path /usr/sbin/smbd Port <Unknown> Host (removed) Source RPM Packages samba-4.1.4-1.fc20.x86_64 Target RPM Packages Policy RPM selinux-policy-3.12.1-122.fc20.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name (removed) Platform Linux (removed) 3.13.3-201.fc20.x86_64 #1 SMP Fri Feb 14 19:08:32 UTC 2014 x86_64 x86_64 Alert Count 12 First Seen 2014-03-04 21:38:23 EST Last Seen 2014-03-04 22:16:11 EST Local ID 5a479d3b-6614-44cc-81dc-63bca8ab10bd Raw Audit Messages type=AVC msg=audit(1393989371.412:1405): avc: denied { setattr } for pid=26165 comm="smbd" name="Shared" dev="dm-4" ino=24905453 scontext=system_u:system_r:smbd_t:s0 tcontext=system_u:object_r:default_t:s0 tclass=dir type=SYSCALL msg=audit(1393989371.412:1405): arch=x86_64 syscall=chmod success=no exit=EACCES a0=7f0c62b078d0 a1=41ed a2=0 a3=3 items=0 ppid=997 pid=26165 auid=4294967295 uid=1000 gid=0 euid=1000 suid=0 fsuid=1000 egid=1000 sgid=0 fsgid=1000 ses=4294967295 tty=(none) comm=smbd exe=/usr/sbin/smbd subj=system_u:system_r:smbd_t:s0 key=(null) Hash: smbd,smbd_t,default_t,dir,setattr Additional info: reporter: libreport-2.1.12 hashmarkername: setroubleshoot kernel: 3.13.3-201.fc20.x86_64 type: libreport
