chcon -t bin_t nacl_helper_bootstrap We are fixing this in F15 and 16, but it is getting a little late in the game to back port for F14. |
Description of problem: SELinux is preventing /opt/google/chrome/chrome from execute access on the file nacl_helper_bootstrap. ***** Plugin catchall_labels (83.8 confidence) suggests ******************** If you want to allow chrome to have execute access on the nacl_helper_bootstrap file Then you need to change the label on nacl_helper_bootstrap Do # semanage fcontext -a -t FILE_TYPE 'nacl_helper_bootstrap' where FILE_TYPE is one of the following: execmem_exec_t, lib_t, abrt_helper_exec_t, ld_so_t, chrome_sandbox_exec_t, bin_t, textrel_shlib_t. Then execute: restorecon -v 'nacl_helper_bootstrap' ***** Plugin catchall (17.1 confidence) suggests *************************** If you believe that chrome should be allowed execute access on the nacl_helper_bootstrap 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 system_u:object_r:usr_t:s0 Target Objects nacl_helper_bootstrap [ file ] Source chrome Source Path /opt/google/chrome/chrome Port <Unknown> Host XXXXXXX Source RPM Packages google-chrome-stable-15.0.874.102-106587 Target RPM Packages Policy RPM selinux-policy-3.9.7-44.fc14 Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name XXXXXXX Platform Linux XXXXXXXX 2.6.35.14-97.fc14.x86_64 #1 SMP Sat Sep 17 00:15:37 UTC 2011 x86_64 x86_64 Alert Count 1 First Seen Tue 25 Oct 2011 09:41:49 PM PDT Last Seen Tue 25 Oct 2011 09:41:49 PM PDT Local ID 3aae5d82-c6ff-4edd-b4b6-60c8e5d3a3b8 Raw Audit Messages type=AVC msg=audit(1319604109.864:39401): avc: denied { execute } for pid=3494 comm="chrome" name="nacl_helper_bootstrap" dev=dm-0 ino=275554 scontext=unconfined_u:unconfined_r:chrome_sandbox_t:s0-s0:c0.c1023 tcontext=system_u:object_r:usr_t:s0 tclass=file type=SYSCALL msg=audit(1319604109.864:39401): arch=x86_64 syscall=execve success=no exit=EACCES a0=7f534703b928 a1=7f5347050760 a2=7fff54004ba0 a3=7fff540009c0 items=0 ppid=1 pid=3494 auid=500 uid=500 gid=500 euid=500 suid=500 fsuid=500 egid=500 sgid=500 fsgid=500 tty=(none) ses=1 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,usr_t,file,execute audit2allow #============= chrome_sandbox_t ============== allow chrome_sandbox_t usr_t:file execute; audit2allow -R #============= chrome_sandbox_t ============== allow chrome_sandbox_t usr_t:file execute; How reproducible: Consistently reproducible.
