Description of problem: SELinux is preventing /usr/bin/python3.4 from 'ioctl' accesses on the file /root/.hplip/hplip_config_usb_printer.log. ***** Plugin catchall (100. confidence) suggests ************************** If you believe that python3.4 should be allowed ioctl access on the hplip_config_usb_printer.log 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 hp-config_usb_p /var/log/audit/audit.log | audit2allow -M mypol # semodule -i mypol.pp Additional Information: Source Context system_u:system_r:cupsd_t:s0-s0:c0.c1023 Target Context system_u:object_r:admin_home_t:s0 Target Objects /root/.hplip/hplip_config_usb_printer.log [ file ] Source hp-config_usb_p Source Path /usr/bin/python3.4 Port <Unknown> Host (removed) Source RPM Packages python3-3.4.3-5.fc23.x86_64 Target RPM Packages Policy RPM selinux-policy-3.13.1-154.fc23.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Permissive Host Name (removed) Platform Linux (removed) 4.2.6-300.fc23.x86_64 #1 SMP Tue Nov 10 19:32:21 UTC 2015 x86_64 x86_64 Alert Count 2 First Seen 2015-11-17 14:55:17 CET Last Seen 2015-11-17 14:59:49 CET Local ID 415db916-35fd-4d36-bbe1-5b91d0f6fa7a Raw Audit Messages type=AVC msg=audit(1447768789.134:882): avc: denied { ioctl } for pid=24535 comm="hp-config_usb_p" path="/root/.hplip/hplip_config_usb_printer.log" dev="dm-1" ino=1447077 scontext=system_u:system_r:cupsd_t:s0-s0:c0.c1023 tcontext=system_u:object_r:admin_home_t:s0 tclass=file permissive=1 type=SYSCALL msg=audit(1447768789.134:882): arch=x86_64 syscall=ioctl success=no exit=ENOTTY a0=5 a1=5401 a2=7ffcb58e48f0 a3=55e276667ec0 items=0 ppid=1 pid=24535 auid=4294967295 uid=0 gid=0 euid=0 suid=0 fsuid=0 egid=0 sgid=0 fsgid=0 tty=(none) ses=4294967295 comm=hp-config_usb_p exe=/usr/bin/python3.4 subj=system_u:system_r:cupsd_t:s0-s0:c0.c1023 key=(null) Hash: hp-config_usb_p,cupsd_t,admin_home_t,file,ioctl Version-Release number of selected component: selinux-policy-3.13.1-154.fc23.noarch Additional info: reporter: libreport-2.6.3 hashmarkername: setroubleshoot kernel: 4.2.6-300.fc23.x86_64 type: libreport
Tim, BTW upstream has been shipping their own SELinux policy module since 3.15.11, see this type enforcement file: https://github.com/jpopelka/hplip/blob/master/selinux/hplip.te
Why is /root/.hplip used for log files?
*** Bug 1279232 has been marked as a duplicate of this bug. ***
Upstream uses ~/.hplip/ for log files and hplip.conf (per-user settings file). The hplip_config_usb_printer.log is written by /usr/bin/hp-config_usb_printer which is started by hplip-printer@.service which is triggered by udev (/usr/lib/udev/rules.d/56-hp_conf_usb.rules) i.e. as root and ~/.hplip/ means /root/.hplip/ in that case.
I've previously had to patch in a special case for USER==root to avoid this someone in HPLIP.
This package has changed ownership in the Fedora Package Database. Reassigning to the new owner of this component.
This message is a reminder that Fedora 23 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 23. 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 '23'. 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 23 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 23 changed to end-of-life (EOL) status on 2016-12-20. Fedora 23 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.
