Summary: SELinux is preventing /usr/lib/chromium-browser/chrome-sandbox access to a leaked udp_socket file descriptor. Detailed Description: [chrome-sandbox has a permissive type (chrome_sandbox_t). This access was not denied.] SELinux denied access requested by the chrome-sandbox command. It looks like this is either a leaked descriptor or chrome-sandbox output was redirected to a file it is not allowed to access. Leaks usually can be ignored since SELinux is just closing the leak and reporting the error. The application does not use the descriptor, so it will run properly. If this is a redirection, you will not get output in the udp_socket. You should generate a bugzilla on selinux-policy, and it will get routed to the appropriate package. You can safely ignore this avc. Allowing Access: You can generate a local policy module to allow this access - see FAQ (http://docs.fedoraproject.org/selinux-faq-fc5/#id2961385) Additional Information: Source Context unconfined_u:unconfined_r:chrome_sandbox_t:s0-s0:c 0.c1023 Target Context unconfined_u:unconfined_r:unconfined_execmem_t:s0- s0:c0.c1023 Target Objects udp_socket [ udp_socket ] Source chrome-sandbox Source Path /usr/lib/chromium-browser/chrome-sandbox Port <Unknown> Host (removed) Source RPM Packages chromium-4.0.285.0-0.1.20091230svn35370.fc12 Target RPM Packages Policy RPM selinux-policy-3.6.32-99.fc12 Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Plugin Name leaks Host Name (removed) Platform Linux (removed) 2.6.32.9-70.fc12.i686 #1 SMP Wed Mar 3 05:14:32 UTC 2010 i686 i686 Alert Count 2 First Seen Sun 14 Mar 2010 07:09:43 AM PDT Last Seen Sun 14 Mar 2010 07:10:21 AM PDT Local ID 1d01302f-7622-4895-a879-af86a5d4c689 Line Numbers Raw Audit Messages node=(removed) type=AVC msg=audit(1268575821.354:41): avc: denied { read write } for pid=4144 comm="chrome-sandbox" path="socket:[61425]" dev=sockfs ino=61425 scontext=unconfined_u:unconfined_r:chrome_sandbox_t:s0-s0:c0.c1023 tcontext=unconfined_u:unconfined_r:unconfined_execmem_t:s0-s0:c0.c1023 tclass=udp_socket node=(removed) type=SYSCALL msg=audit(1268575821.354:41): arch=40000003 syscall=11 success=yes exit=0 a0=8d2fd54 a1=b5255418 a2=8d2ff10 a3=b5255418 items=0 ppid=3668 pid=4144 auid=500 uid=500 gid=500 euid=0 suid=0 fsuid=0 egid=500 sgid=500 fsgid=500 tty=(none) ses=1 comm="chrome-sandbox" exe="/usr/lib/chromium-browser/chrome-sandbox" subj=unconfined_u:unconfined_r:chrome_sandbox_t:s0-s0:c0.c1023 key=(null) Hash String generated from leaks,chrome-sandbox,chrome_sandbox_t,unconfined_execmem_t,udp_socket,read,write audit2allow suggests: #============= chrome_sandbox_t ============== allow chrome_sandbox_t unconfined_execmem_t:udp_socket { read write };
Miroslav add this to chrome_domtrans_sandbox ifdef(`hide_broken_symptoms', ` dontaudit chrome_sandbox_t $1:socket_class_set { read write }; ') This is what we have in F13.
