Colord should not need these accesses. Indeed, execstack is not required. If you change /etc/colord.conf to have "UseSANE=false", does the denial go away? libsane seems to be pretty insane sometimes. Yes - I made the change you suggested and the denial went away. I shall change back to "true" and wait for the future fix. Jim Dutton *** This bug has been marked as a duplicate of bug 741086 *** |
SELinux is preventing /usr/libexec/colord from using the 'execstack' accesses on a process. ***** Plugin catchall (100. confidence) suggests *************************** If you believe that colord should be allowed execstack access on processes labeled colord_t 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 colord /var/log/audit/audit.log | audit2allow -M mypol # semodule -i mypol.pp Additional Information: Source Context system_u:system_r:colord_t:s0-s0:c0.c1023 Target Context system_u:system_r:colord_t:s0-s0:c0.c1023 Target Objects Unknown [ process ] Source colord Source Path /usr/libexec/colord Port <Unknown> Host (removed) Source RPM Packages colord-0.1.7-1.fc15 Target RPM Packages Policy RPM selinux-policy-3.9.16-35.fc15 Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name (removed) Platform Linux (removed) 2.6.40-4.fc15.i686 #1 SMP Fri Jul 29 18:54:39 UTC 2011 i686 i686 Alert Count 1 First Seen Sat 06 Aug 2011 10:38:30 AM EDT Last Seen Sat 06 Aug 2011 10:38:30 AM EDT Local ID 526bb5d2-7d68-4c53-8d41-cf44e879b5a0 Raw Audit Messages type=AVC msg=audit(1312641510.641:19): avc: denied { execstack } for pid=1070 comm="colord" scontext=system_u:system_r:colord_t:s0-s0:c0.c1023 tcontext=system_u:system_r:colord_t:s0-s0:c0.c1023 tclass=process type=AVC msg=audit(1312641510.641:19): avc: denied { execmem } for pid=1070 comm="colord" scontext=system_u:system_r:colord_t:s0-s0:c0.c1023 tcontext=system_u:system_r:colord_t:s0-s0:c0.c1023 tclass=process type=SYSCALL msg=audit(1312641510.641:19): arch=i386 syscall=mprotect success=yes exit=0 a0=bff18000 a1=1000 a2=1000007 a3=bff16f24 items=0 ppid=1 pid=1070 auid=4294967295 uid=0 gid=0 euid=0 suid=0 fsuid=0 egid=0 sgid=0 fsgid=0 tty=(none) ses=4294967295 comm=colord exe=/usr/libexec/colord subj=system_u:system_r:colord_t:s0-s0:c0.c1023 key=(null) Hash: colord,colord_t,colord_t,process,execstack audit2allow #============= colord_t ============== allow colord_t self:process { execstack execmem }; audit2allow -R #============= colord_t ============== allow colord_t self:process { execstack execmem };
