Description of problem:
Started wine.
SELinux is preventing wine-preloader from using the 'execheap' accesses on a process.

*****  Plugin allow_execheap (53.1 confidence) suggests   ********************

Pokud nemáte za to, že by wine-preloader měl mít potřebu mapovat zásobník paměti (heap), který je zapisovatelný i spustitelný zároveň.
Then měli byste nahlásit chybu. Toto je potenciálně nebezpečný přístup.
Do
kontaktujte bezpečnostního správce a nahlašte mu tento problém.

*****  Plugin catchall_boolean (42.6 confidence) suggests   ******************

Pokud chcete allow selinuxuser to execheap
Then musíte o tomto SELinuxu říct povolením booleovské hodnoty „selinuxuser_execheap“.

Do
setsebool -P selinuxuser_execheap 1

*****  Plugin catchall (5.76 confidence) suggests   **************************

Pokud jste přesvědčeni, že má wine-preloader mít ve výchozím stavu přístup execheap na procesy se značkou unconfined_t.
Then měli byste tento problém nahlásit jako chybu.
Abyste přístup povolili, můžete vygenerovat lokální modul pravidel.
Do
prozatím tento přístup povolíte příkazy:
# ausearch -c 'wine-preloader' --raw | audit2allow -M my-winepreloader
# semodule -X 300 -i my-winepreloader.pp
