Did you just plug in a printer device when this happened? This message is a reminder that Fedora 13 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 13. It is Fedora's policy to close all bug reports from releases that are no longer maintained.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 WONTFIX if it remains open with a Fedora 'version' of '13'. 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 prior to Fedora 13's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 13 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 please change the 'version' of this bug to the applicable version. If you are unable to change the version, please add a comment here and someone will do it for you. 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. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping Fedora 13 changed to end-of-life (EOL) status on 2011-06-25. Fedora 13 is no longer maintained, which means that it will not receive any further security or bug fix updates.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. Thank you for reporting this bug and we are sorry it could not be fixed. |
Summary: SELinux is preventing /usr/bin/python "read write" access to device 005. Detailed Description: SELinux has denied hpfax "read write" access to device 005. 005 is mislabeled, this device has the default label of the /dev directory, which should not happen. All Character and/or Block Devices should have a label. You can attempt to change the label of the file using restorecon -v '005'. If this device remains labeled device_t, then this is a bug in SELinux policy. Please file a bg report. If you look at the other similar devices labels, ls -lZ /dev/SIMILAR, and find a type that would work for 005, you can use chcon -t SIMILAR_TYPE '005', If this fixes the problem, you can make this permanent by executing semanage fcontext -a -t SIMILAR_TYPE '005' If the restorecon changes the context, this indicates that the application that created the device, created it without using SELinux APIs. If you can figure out which application created the device, please file a bug report against this application. Allowing Access: Attempt restorecon -v '005' or chcon -t SIMILAR_TYPE '005' Additional Information: Source Context system_u:system_r:hplip_t:s0-s0:c0.c1023 Target Context system_u:object_r:device_t:s0 Target Objects 005 [ chr_file ] Source hpfax Source Path /usr/bin/python Port <Unknown> Host (removed) Source RPM Packages python-2.6.4-27.fc13 Target RPM Packages Policy RPM selinux-policy-3.7.19-62.fc13 Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Plugin Name device Host Name (removed) Platform Linux (removed) 2.6.34.7-56.fc13.i686.PAE #1 SMP Wed Sep 15 03:27:15 UTC 2010 i686 i686 Alert Count 1 First Seen Fri 08 Oct 2010 12:04:55 PM IST Last Seen Fri 08 Oct 2010 12:04:55 PM IST Local ID 392f1739-a7d2-491b-b67a-3de0570dac99 Line Numbers Raw Audit Messages node=(removed) type=AVC msg=audit(1286519695.28:53): avc: denied { read write } for pid=16995 comm="hpfax" name="005" dev=devtmpfs ino=129656 scontext=system_u:system_r:hplip_t:s0-s0:c0.c1023 tcontext=system_u:object_r:device_t:s0 tclass=chr_file node=(removed) type=SYSCALL msg=audit(1286519695.28:53): arch=40000003 syscall=5 success=no exit=-13 a0=bfebf6d0 a1=2 a2=1 a3=a325f90 items=0 ppid=16992 pid=16995 auid=4294967295 uid=0 gid=7 euid=0 suid=0 fsuid=0 egid=7 sgid=7 fsgid=7 tty=(none) ses=4294967295 comm="hpfax" exe="/usr/bin/python" subj=system_u:system_r:hplip_t:s0-s0:c0.c1023 key=(null) Hash String generated from device,hpfax,hplip_t,device_t,chr_file,read,write audit2allow suggests: #============= hplip_t ============== allow hplip_t device_t:chr_file { read write };
