Are you able to get it again? We have a duplicate of this bug, which I think is a kernel issue. See my comments in BZ #1013878, there is nothing we can do to resolve this in the kernel. Reassigning to policy. *** Bug 1013878 has been marked as a duplicate of this bug. *** I tried to add a type transition. This message is a reminder that Fedora 20 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 20. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a Fedora 'version' of '20'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 20 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. Fedora 20 changed to end-of-life (EOL) status on 2015-06-23. Fedora 20 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. If you are unable to reopen this bug, please file a new report against the current release. If you experience problems, please add a comment to this bug. Thank you for reporting this bug and we are sorry it could not be fixed. The needinfo request[s] on this closed bug have been removed as they have been unresolved for 1000 days |
Description of problem: tried to set up samba SELinux is preventing /usr/sbin/smbd from read, write access on the file /SYSV07021999 (deleted). ***** Plugin restorecon (63.0 confidence) suggests ************************ If you want to fix the label. /SYSV07021999 (deleted) default label should be etc_runtime_t. Then you can run restorecon. Do # /sbin/restorecon -v /SYSV07021999 (deleted) ***** Plugin samba_share (32.3 confidence) suggests *********************** If you want to allow smbd to have read write access on the SYSV07021999 (deleted) file Then you need to change the label on '/SYSV07021999.(deleted)' Do # semanage fcontext -a -t samba_share_t '/SYSV07021999.(deleted)' # restorecon -v '/SYSV07021999.(deleted)' ***** Plugin catchall_boolean (5.5 confidence) suggests ******************* If you want to allow samba to export all rw Then you must tell SELinux about this by enabling the 'samba_export_all_rw' boolean. You can read 'None' man page for more details. Do setsebool -P samba_export_all_rw 1 ***** Plugin catchall (1.12 confidence) suggests ************************** If you believe that smbd should be allowed read write access on the SYSV07021999 (deleted) file 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:tmpfs_t:s0 Target Objects /SYSV07021999 (deleted) [ file ] Source smbd Source Path /usr/sbin/smbd Port <Unknown> Host (removed) Source RPM Packages samba-4.1.1-1.fc20.x86_64 Target RPM Packages Policy RPM selinux-policy-3.12.1-90.fc20.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Permissive Host Name (removed) Platform Linux (removed) 3.11.8-300.fc20.x86_64 #1 SMP Wed Nov 13 16:34:27 UTC 2013 x86_64 x86_64 Alert Count 4 First Seen 2013-11-23 18:42:00 EET Last Seen 2013-11-23 19:32:05 EET Local ID b6f63cd2-bb06-49d9-81d2-36297915cdcf Raw Audit Messages type=AVC msg=audit(1385227925.30:571): avc: denied { read write } for pid=2586 comm="smbd" path=2F535953563037303231393939202864656C6574656429 dev="tmpfs" ino=0 scontext=system_u:system_r:smbd_t:s0 tcontext=system_u:object_r:tmpfs_t:s0 tclass=file type=SYSCALL msg=audit(1385227925.30:571): arch=x86_64 syscall=shmat success=yes exit=140348486328320 a0=0 a1=0 a2=0 a3=7fa56a9147b8 items=0 ppid=1 pid=2586 auid=4294967295 uid=0 gid=0 euid=0 suid=0 fsuid=0 egid=0 sgid=0 fsgid=0 ses=4294967295 tty=(none) comm=smbd exe=/usr/sbin/smbd subj=system_u:system_r:smbd_t:s0 key=(null) Hash: smbd,smbd_t,tmpfs_t,file,read,write Additional info: reporter: libreport-2.1.9 hashmarkername: setroubleshoot kernel: 3.11.8-300.fc20.x86_64 type: libreport
