Description of problem: Enabled firefox's electrolysis mode that uses separate processes for web rendering and for the browser. Tried print-to-pdf from a page, and got this. SELinux is preventing 57656220436F6E74656E74 from 'write' accesses on the file /home/amit/some-file.pdf. ***** Plugin mozplugger (99.1 confidence) suggests ************************ If you want to use the plugin package Then you must turn off SELinux controls on the Firefox plugins. Do # setsebool -P unconfined_mozilla_plugin_transition 0 ***** Plugin catchall (1.81 confidence) suggests ************************** If you believe that 57656220436F6E74656E74 should be allowed write access on the some-file.pdf 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: # ausearch -c '57656220436F6E74656E74' --raw | audit2allow -M my-57656220436F6E74656E74 # semodule -X 300 -i my-57656220436F6E74656E74.pp Additional Information: Source Context unconfined_u:unconfined_r:mozilla_plugin_t:s0-s0:c 0.c1023 Target Context unconfined_u:object_r:user_home_t:s0 Target Objects /home/amit/canada/some-file.pdf [ file ] Source 57656220436F6E74656E74 Source Path 57656220436F6E74656E74 Port <Unknown> Host (removed) Source RPM Packages Target RPM Packages Policy RPM selinux-policy-3.13.1-191.12.fc24.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name (removed) Platform Linux (removed) 4.6.6-300.fc24.x86_64 #1 SMP Wed Aug 10 21:07:35 UTC 2016 x86_64 x86_64 Alert Count 2 First Seen 2016-08-26 11:06:27 EDT Last Seen 2016-08-26 11:10:18 EDT Local ID 2df7dd9f-84d3-42b2-886b-9c298518e811 Raw Audit Messages type=AVC msg=audit(1472224218.308:720): avc: denied { write } for pid=5095 comm=57656220436F6E74656E74 path="/home/amit/some-file.pdf" dev="dm-6" ino=826466041 scontext=unconfined_u:unconfined_r:mozilla_plugin_t:s0-s0:c0.c1023 tcontext=unconfined_u:object_r:user_home_t:s0 tclass=file permissive=1 Hash: 57656220436F6E74656E74,mozilla_plugin_t,user_home_t,file,write Version-Release number of selected component: selinux-policy-3.13.1-191.12.fc24.noarch Additional info: reporter: libreport-2.7.2 hashmarkername: setroubleshoot kernel: 4.6.6-300.fc24.x86_64 type: libreport
This looks like the tool is printing from a plugin, in this case I think you will have to remove the pluign protection, if you want to be able to print from them. setsebool -P unconfined_mozilla_plugin_transition 0
I don't have any plugins to print to pdf, if that's what it's doing. I guess it's just the multi-process thing, where the web context is trying to print now instead of the earlier firefox process.
I've got all plugins and addons disabled to test electrolysis, and I trigger this. Note: electrolysis is still disabled (for now) in the default Fedora Firefox rpm.
This package has changed ownership in the Fedora Package Database. Reassigning to the new owner of this component.
Any news on this? It's also preventing access to /var (e.g.: /var/www). Since firefox-52.0.2-2.fc25 e10s is finally available in Fedora and I started getting these alerts with enforcing enabled, the browser itself is being classified as a plugin reading local munin data in /var/www type=AVC msg=audit(1491663112.926:42849): avc: denied { read } for pid=5529 comm=57656220436F6E74656E74 name="var" dev="dm-1" ino=1310722 scontext=unconfined_u:unconfined_r:mozilla_plugin_t:s0-s0:c0.c1023 tcontext=system_u:object_r:var_t:s0 tclass=dir permissive=0 print to file type=AVC msg=audit(1491663634.076:42973): avc: denied { create } for pid=5529 comm=57656220436F6E74656E74 name="mozilla.pdf" scontext=unconfined_u:unconfined_r:mozilla_plugin_t:s0-s0:c0.c1023 tcontext=unconfined_u:object_r:user_home_dir_t:s0 tclass=file permissive=0
This message is a reminder that Fedora 24 is nearing its end of life. Approximately 2 (two) weeks from now Fedora will stop maintaining and issuing updates for Fedora 24. 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 '24'. 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 24 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 24 changed to end-of-life (EOL) status on 2017-08-08. Fedora 24 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.
