This message is a reminder that Fedora 21 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 21. It is Fedora's policy to close all bug reports from releases that are no longer maintained.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 '21'. 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 21 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 21 changed to end-of-life (EOL) status on 2015-12-01. Fedora 21 is no longer maintained, which means that it will not receive any further security or bug fix updates.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. |
Description of problem: Using a Windows 10 VM with client access to Samba shares. SELinux is preventing /usr/sbin/smbd from 'getattr' accesses on the file /usr/sbin/ssmtp. ***** Plugin samba_share (75.5 confidence) suggests *********************** If you want to allow smbd to have getattr access on the ssmtp file Then you need to change the label on '/usr/sbin/ssmtp' Do # semanage fcontext -a -t samba_share_t '/usr/sbin/ssmtp' # restorecon -v '/usr/sbin/ssmtp' ***** Plugin catchall_boolean (12.2 confidence) suggests ****************** If you want to allow samba to share any file/directory read only. Then you must tell SELinux about this by enabling the 'samba_export_all_ro' boolean. You can read 'sendmail_selinux' man page for more details. Do setsebool -P samba_export_all_ro 1 ***** Plugin catchall_boolean (12.2 confidence) suggests ****************** If you want to allow samba to share any file/directory read/write. Then you must tell SELinux about this by enabling the 'samba_export_all_rw' boolean. You can read 'sendmail_selinux' man page for more details. Do setsebool -P samba_export_all_rw 1 ***** Plugin catchall (1.97 confidence) suggests ************************** If you believe that smbd should be allowed getattr access on the ssmtp file by default. Then you should report this as a bug. You can generate a local policy module to allow this access.
