Subject: [PATCH] selinux: don't log SELINUX_INFO and SELINUX_WARNING messages
|
|
|
923a60 |
to audit
|
|
|
923a60 |
|
|
|
923a60 |
Previously we logged even info message from libselinux as USER_AVC's to
|
|
|
923a60 |
audit. For example, setting SELinux to permissive mode generated
|
|
|
923a60 |
following audit message,

type=USER_AVC msg=audit(1551198569.423:334): pid=1 uid=0 auid=4294967295 ses=4294967295 subj=system_u:system_r:init_t:s0 msg='avc: received setenforce notice (enforcing=0) exe="/usr/lib/systemd/systemd" sauid=0 hostname=? addr=? terminal=?'

This is unnecessary and wrong at the same time. First, kernel already
|
|
|
923a60 |
records audit event that SELinux was switched to permissive mode, also
|
|
|
923a60 |
the type of the message really shouldn't be USER_AVC.
|
|
|
923a60 |
|
|
|
923a60 |
Let's ignore SELINUX_WARNING and SELINUX_INFO and forward to audit only
|
|
|
923a60 |
USER_AVC's and errors as these two libselinux message types have clear
|
|
|
923a60 |
mapping to audit message types.
