SELinux is preventing hl2_linux from using the 'execheap' accesses on a process.

Description of problem: SELinux is preventing hl2_linux from using the 'execheap' accesses on a process. ***** Plugin allow_execheap (53.1 confidence) suggests ******************** If no cree que hl2_linux debería necesitar mapear memoria del heap que sea a la vez escribible y ejecutable. Then necesita informar de un error. Éste es un acceso potencialmente peligroso. Do póngase en contacto con su administrador de seguridad e informe de este problema. ***** Plugin catchall_boolean (42.6 confidence) suggests ****************** If quiere allow selinuxuser to execheap Then debe informar a SELinux de ésto activando el booleano 'selinuxuser_execheap'. Do setsebool -P selinuxuser_execheap 1 ***** Plugin catchall (5.76 confidence) suggests ************************** If cree que de manera predeterminada, hl2_linux debería permitir acceso execheap sobre procesos etiquetados como unconfined_t. Then debería reportar esto como un error. Puede generar un módulo de política local para permitir este acceso. Do allow this access for now by executing: # ausearch -c 'hl2_linux' --raw | audit2allow -M my-hl2linux # semodule -X 300 -i my-hl2linux.pp Additional Information: Source Context unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1 023 Target Context unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1 023 Target Objects Unknown [ process ] Source hl2_linux Source Path hl2_linux Port <Desconocido> Host (removed) Source RPM Packages Target RPM Packages Policy RPM selinux-policy-3.13.1-260.3.fc26.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name (removed) Platform Linux (removed) 4.11.11-300.fc26.x86_64 #1 SMP Mon Jul 17 16:32:11 UTC 2017 x86_64 x86_64 Alert Count 1 First Seen 2017-07-30 13:49:39 -05 Last Seen 2017-07-30 13:49:39 -05 Local ID 8cf678ab-cd49-4197-b1c5-434259dfa224 Raw Audit Messages type=AVC msg=audit(1501440579.734:248): avc: denied { execheap } for pid=3975 comm="hl2_linux" scontext=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 tcontext=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 tclass=process permissive=0 Hash: hl2_linux,unconfined_t,unconfined_t,process,execheap Version-Release number of selected component: selinux-policy-3.13.1-260.3.fc26.noarch Additional info: component: selinux-policy reporter: libreport-2.9.1 hashmarkername: setroubleshoot kernel: 4.11.11-300.fc26.x86_64 type: libreport Potential duplicate: bug 979647
This message is a reminder that Fedora 26 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 26. 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 '26'. 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 26 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.
