Description of problem: attempted to install the zotero chrome extension but chrome does not have permission to change the file SELinux is preventing /opt/google/chrome/chrome from 'execute' accesses on the file /home/leithal/Downloads/Zotero_linux-x86_64/xulrunner/libnss3.so. ***** Plugin chrome (98.5 confidence) suggests **************************** If you want to use the plugin package Then you must turn off SELinux controls on the Chrome plugins. Do # setsebool -P unconfined_chrome_sandbox_transition 0 ***** Plugin catchall (2.46 confidence) suggests ************************** If you believe that chrome should be allowed execute access on the libnss3.so 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 Additional Information: Source Context unconfined_u:unconfined_r:chrome_sandbox_t:s0-s0:c 0.c1023 Target Context unconfined_u:object_r:user_home_t:s0 Target Objects /home/leithal/Downloads/Zotero_linux- x86_64/xulrunner/libnss3.so [ file ] Source chrome Source Path /opt/google/chrome/chrome Port <Unknown> Host (removed) Source RPM Packages google-chrome-stable-32.0.1700.77-1.x86_64 Target RPM Packages Policy RPM selinux-policy-3.12.1-106.fc20.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Permissive Host Name (removed) Platform Linux (removed) 3.12.7-300.fc20.x86_64 #1 SMP Fri Jan 10 15:35:31 UTC 2014 x86_64 x86_64 Alert Count 2 First Seen 2014-01-15 12:36:08 EST Last Seen 2014-01-15 12:43:29 EST Local ID f564d97a-1168-4d78-bc42-c993e9aac35e Raw Audit Messages type=AVC msg=audit(1389750209.644:544): avc: denied { execute } for pid=2694 comm="chrome" path="/home/leithal/Downloads/Zotero_linux-x86_64/xulrunner/libnss3.so" dev="dm-2" ino=30540307 scontext=unconfined_u:unconfined_r:chrome_sandbox_t:s0-s0:c0.c1023 tcontext=unconfined_u:object_r:user_home_t:s0 tclass=file type=SYSCALL msg=audit(1389750209.644:544): arch=x86_64 syscall=mmap success=yes exit=140696508162048 a0=0 a1=307d78 a2=5 a3=802 items=0 ppid=0 pid=2694 auid=1000 uid=1000 gid=1000 euid=1000 suid=1000 fsuid=1000 egid=1000 sgid=1000 fsgid=1000 ses=1 tty=(none) comm=chrome exe=/opt/google/chrome/chrome subj=unconfined_u:unconfined_r:chrome_sandbox_t:s0-s0:c0.c1023 key=(null) Hash: chrome,chrome_sandbox_t,user_home_t,file,execute Additional info: reporter: libreport-2.1.11 hashmarkername: setroubleshoot kernel: 3.12.7-300.fc20.x86_64 type: libreport
If you want to use this way you can either turn off the protection # setsebool -P unconfined_chrome_sandbox_transition 0 or you can try to change the labeling # chcon -t lib_t /home/leithal/Downloads/Zotero_linux-x86_64/xulrunner/libnss3.so to see if it works correctly.
