Looks like leaked file descriptor. Yeah, almost certainly. Thanks for reassigning this. I can report the same problem happens in my FC23 machine. This issue is reproducible on my RHEL7.3 system with `selinux-policy-3.13.1-102.el7_3.4.noarch` and `denyhosts-2.9-4.el7.noarch`. uname -r 3.10.0-514.el7.x86_64 This message is a reminder that Fedora 23 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 23. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a Fedora 'version' of '23'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 23 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. Has reoccurred on an upgraded F25 machine. This message is a reminder that Fedora 25 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 25.

Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. Fedora 25 changed to end-of-life (EOL) status on 2017-12-12. Fedora 25 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. If you are unable to reopen this bug, please file a new report against the current release. If you experience problems, please add a comment to this bug. Thank you for reporting this bug and we are sorry it could not be fixed. |
Description of problem: SELinux is preventing /usr/sbin/xtables-multi from 'write' accesses on the file /run/lock/subsys/denyhosts. ***** Plugin leaks (86.2 confidence) suggests ***************************** If you want to ignore xtables-multi trying to write access the denyhosts file, because you believe it should not need this access. Then you should report this as a bug. You can generate a local policy module to dontaudit this access. Do # grep /usr/sbin/xtables-multi /var/log/audit/audit.log | audit2allow -D -M mypol # semodule -i mypol.pp ***** Plugin catchall (14.7 confidence) suggests ************************** If you believe that xtables-multi should be allowed write access on the denyhosts 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 iptables /var/log/audit/audit.log | audit2allow -M mypol # semodule -i mypol.pp Additional Information: Source Context system_u:system_r:iptables_t:s0 Target Context system_u:object_r:denyhosts_var_lock_t:s0 Target Objects /run/lock/subsys/denyhosts [ file ] Source iptables Source Path /usr/sbin/xtables-multi Port <Unknown> Host (removed) Source RPM Packages Target RPM Packages Policy RPM <Unknown> Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name (removed) Platform Linux (removed) 4.3.5-300.fc23.x86_64 #1 SMP Mon Feb 1 03:18:41 UTC 2016 x86_64 x86_64 Alert Count 69 First Seen 2015-11-14 15:07:18 GMT Last Seen 2016-02-22 08:52:19 GMT Local ID a0899179-0ee9-4c87-9424-c39310865db9 Raw Audit Messages type=AVC msg=audit(1456131139.609:409): avc: denied { write } for pid=3838 comm="iptables" path="/run/lock/subsys/denyhosts" dev="tmpfs" ino=23198 scontext=system_u:system_r:iptables_t:s0 tcontext=system_u:object_r:denyhosts_var_lock_t:s0 tclass=file permissive=0 type=AVC msg=audit(1456131139.609:409): avc: denied { append } for pid=3838 comm="iptables" path="/etc/hosts.deny" dev="dm-0" ino=4720538 scontext=system_u:system_r:iptables_t:s0 tcontext=system_u:object_r:net_conf_t:s0 tclass=file permissive=0 type=SYSCALL msg=audit(1456131139.609:409): arch=x86_64 syscall=execve success=yes exit=0 a0=558d214e3f10 a1=558d214e3ff0 a2=558d214e2b60 a3=7f2a49ebebd8 items=0 ppid=1004 pid=3838 auid=4294967295 uid=0 gid=0 euid=0 suid=0 fsuid=0 egid=0 sgid=0 fsgid=0 tty=(none) ses=4294967295 comm=iptables exe=/usr/sbin/xtables-multi subj=system_u:system_r:iptables_t:s0 key=(null) Hash: iptables,iptables_t,denyhosts_var_lock_t,file,write Additional info: reporter: libreport-2.6.4 hashmarkername: setroubleshoot kernel: 4.3.5-300.fc23.x86_64 type: libreport Potential duplicate: bug 1259178
