If problems still persist, please make note of it in this bug report. Description of problem: Trying to pring to a Brother HL-5250DN printer, it actually printed without the necessary SELinux bypass mechanisms (grep brprintconflsr2 /var/log/audit/audit.log | audit2allow -M mypol) Version-Release number of selected component: selinux-policy-3.13.1-158.11.fc23.noarch Additional info: reporter: libreport-2.6.4 hashmarkername: setroubleshoot kernel: 4.4.6-300.fc23.x86_64 type: libreport |
Description of problem: Simply trying to print to a network printer... (of Brother's make HL5250-DN I think) SELinux is preventing /usr/bin/brprintconflsr2 from 'execute' accesses on the file /etc/ld.so.cache. ***** Plugin catchall (100. confidence) suggests ************************** If you believe that brprintconflsr2 should be allowed execute access on the ld.so.cache 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 brprintconflsr2 /var/log/audit/audit.log | audit2allow -M mypol # semodule -i mypol.pp Additional Information: Source Context system_u:system_r:cupsd_t:s0-s0:c0.c1023 Target Context unconfined_u:object_r:ld_so_cache_t:s0 Target Objects /etc/ld.so.cache [ file ] Source brprintconflsr2 Source Path /usr/bin/brprintconflsr2 Port <Unknown> Host (removed) Source RPM Packages brhl5250dnlpr-2.0.1-1.i386 Target RPM Packages glibc-2.22-6.fc23.x86_64 glibc-2.22-6.fc23.i686 Policy RPM selinux-policy-3.13.1-158.fc23.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name (removed) Platform Linux (removed) 4.2.8-300.fc23.x86_64 #1 SMP Tue Dec 15 16:49:06 UTC 2015 x86_64 x86_64 Alert Count 10 First Seen 2015-12-30 01:52:30 IST Last Seen 2015-12-30 01:52:30 IST Local ID 7ccb9d10-833d-467f-92e4-606837c8e96d Raw Audit Messages type=AVC msg=audit(1451433150.948:17723): avc: denied { execute } for pid=6876 comm="rawtobr2" path="/etc/ld.so.cache" dev="dm-1" ino=2754557 scontext=system_u:system_r:cupsd_t:s0-s0:c0.c1023 tcontext=unconfined_u:object_r:ld_so_cache_t:s0 tclass=file permissive=0 type=SYSCALL msg=audit(1451433150.948:17723): arch=i386 syscall=lgetxattr per=400000 success=no exit=EACCES a0=0 a1=357dc a2=1 a3=2 items=0 ppid=6846 pid=6876 auid=4294967295 uid=4 gid=7 euid=4 suid=4 fsuid=4 egid=7 sgid=7 fsgid=7 tty=(none) ses=4294967295 comm=rawtobr2 exe=/usr/local/Brother/lpd/rawtobr2 subj=system_u:system_r:cupsd_t:s0-s0:c0.c1023 key=(null) Hash: brprintconflsr2,cupsd_t,ld_so_cache_t,file,execute Version-Release number of selected component: selinux-policy-3.13.1-158.fc23.noarch Additional info: reporter: libreport-2.6.3 hashmarkername: setroubleshoot kernel: 4.2.8-300.fc23.x86_64 type: libreport
