SELinux brání pool-geoclue z write přístupu k sock_file io.systemd.Resolve.
***** Plugin catchall (100. důvěry) naznačuje*********************************
Pokud jste přesvědčeni, že má pool-geoclue mít ve výchozím stavu přístup write na io.systemd.Resolve sock_file.
Pak měli byste tento problém nahlásit jako chybu.
Abyste přístup povolili, můžete vygenerovat lokální modul pravidel.
Udělejte
prozatím tento přístup povolíte příkazy:
# ausearch -c 'pool-geoclue' --raw | audit2allow -M my-poolgeoclue
# semodule -X 300 -i my-poolgeoclue.pp

The fix seems not have been complex enough. https://github.com/fedora-selinux/selinux-policy/pull/551 commit d356d9fbe2a5de71c7811fc8797302eef4102163 (HEAD -> rawhide, upstream/rawhide)

Allow domain write to systemd-resolved PID socket files
Previously, the permission was allowed for the nsswitch_domain
attribute which turned out not to be sufficient.

This bug appears to have been reported against 'rawhide' during the Fedora 34 development cycle. Changing version to 34. |
Description of problem: Just happens periodically on my laptop after upgrading it to Rawhide. I don't seem to have to do anything in particular to trigger it. SELinux is preventing pool-geoclue from 'write' accesses on the sock_file io.systemd.Resolve. ***** Plugin catchall (100. confidence) suggests ************************** If you believe that pool-geoclue should be allowed write access on the io.systemd.Resolve sock_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: # ausearch -c 'pool-geoclue' --raw | audit2allow -M my-poolgeoclue # semodule -X 300 -i my-poolgeoclue.pp Additional Information: Source Context system_u:system_r:geoclue_t:s0 Target Context system_u:object_r:systemd_resolved_var_run_t:s0 Target Objects io.systemd.Resolve [ sock_file ] Source pool-geoclue Source Path pool-geoclue Port <Unknown> Host (removed) Source RPM Packages Target RPM Packages SELinux Policy RPM selinux-policy-targeted-3.14.7-8.fc34.noarch Local Policy RPM selinux-policy-targeted-3.14.7-8.fc34.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name (removed) Platform Linux (removed) 5.10.0-0.rc4.78.fc34.x86_64 #1 SMP Mon Nov 16 17:13:58 UTC 2020 x86_64 x86_64 Alert Count 109 First Seen 2020-11-20 11:51:42 PST Last Seen 2020-11-20 22:44:31 PST Local ID fb400941-5e95-4ea1-a203-48e359341267 Raw Audit Messages type=AVC msg=audit(1605941071.614:1664): avc: denied { write } for pid=1413 comm="pool-geoclue" name="io.systemd.Resolve" dev="tmpfs" ino=1647 scontext=system_u:system_r:geoclue_t:s0 tcontext=system_u:object_r:systemd_resolved_var_run_t:s0 tclass=sock_file permissive=0 Hash: pool-geoclue,geoclue_t,systemd_resolved_var_run_t,sock_file,write Version-Release number of selected component: selinux-policy-targeted-3.14.7-8.fc34.noarch Additional info: component: selinux-policy reporter: libreport-2.14.0 hashmarkername: setroubleshoot kernel: 5.10.0-0.rc4.78.fc34.x86_64 type: libreport
