Description of problem: Start google-chrome-beta-28.0.1500.20-201172.x86_64 Additional info: hashmarkername: setroubleshoot kernel: 3.9.2-200.fc18.x86_64 type: libreport I'm running F17 with updates-testing enabled. Here's my similar error:
SELinux is preventing /opt/google/chrome/chrome from create access on the file libpeerconnection.log.
***** Plugin catchall (100. confidence) suggests ***************************
If you believe that chrome should be allowed create access on the libpeerconnection.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 chrome /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

What is /home/scottt/libpeerconnection.log? Execute # restorecon -R -v /home/scottt/libpeerconnection.log (In reply to Miroslav Grepl from comment #3) > What is /home/scottt/libpeerconnection.log? "libpeerconnection" is part of Google Chrome's implementation of WebRTC, e.g. http://git.chromium.org/gitweb/?p=chromium/chromium.git;a=blob;f=chrome/chrome_browser.gypi;h=711e4fbb55c4fdc03c7c19995d30a909dd522107;hb=fea174faa9f61b1a59f4136421e83d7f63b9331f#l2953 Basically UDP with some basic NATT abilities in the browser exposed to Javascript. Used for video calls etc. The fact that google-chrome-beta-28.0.1500.20-201172.x86_64 wants to write a log file in $HOME is probably just sloppy coding. > Execute > # restorecon -R -v /home/scottt/libpeerconnection.log $ ls -Z ~/libpeerconnection.log -rw-rw-r--. scottt scottt unconfined_u:object_r:user_home_dir_t:s0 /home/scottt/libpeerconnection.log $ restorecon -R -v ~/libpeerconnection.log restorecon reset /home/scottt/libpeerconnection.log context unconfined_u:object_r:user_home_dir_t:s0->unconfined_u:object_r:user_home_t:s0 On my 2 F17 installs, SELinux prevented libpeerconnection.log from being created. I created an empty libpeerconnection.log in my home directory, then, executed restorecon -R -v /home/GoinEasy9/libpeerconnection.log and the AVC errors disappeared. *** This bug has been marked as a duplicate of bug 960792 *** *** Bug 977170 has been marked as a duplicate of this bug. *** |
