This is happening to me on each start since Monday (when I first got 4.7.x kernel):
SELinux is preventing google-chrome-b from create access on the file 63.
***** Plugin catchall (100. confidence) suggests **************************
If sie denken, dass es google-chrome-b standardmäßig erlaubt sein sollte, create Zugriff auf 63 file zu erhalten.
Then sie sollten dies als Fehler melden.
Um diesen Zugriff zu erlauben, können Sie ein lokales Richtlinien-Modul erstellen.
Do
allow this access for now by executing:
# ausearch -c 'google-chrome-b' --raw | audit2allow -M my-googlechromeb
# semodule -X 300 -i my-googlechromeb.pp

Is this a low priority as it impacts all users of chrome as it does not leave the browser in the same state it was left on following a reboot. This AVC is not causing an issue. The call ends up succeeding. THe browser not being in the same state is unrelated to this AVC. We should be adding a dontaudit rules. Processes are not able to "create" files in /proc, which is what this AVC is reporting. A change as made to the kernel to report these AVC's when a process tries to open(CREATE) a file that already exists. This AVC is generated but the actual open command succeeds. *** This bug has been marked as a duplicate of bug 1345836 *** |
Description of problem: start Google Chrome beta SELinux is preventing google-chrome-b from 'create' accesses on the file 63. ***** Plugin catchall (100. confidence) suggests ************************** If you believe that google-chrome-b should be allowed create access on the 63 file by default. Then you should report this as a bug. You can generate a local policy module to allow this access.
