[RFC PATCH 05/24] setfiles: do not issue AUDIT_FS_RELABEL on dry run

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Do not issue an audit event of type AUDIT_FS_RELABEL in case of a
passive check.

Print the reason for an audit_open(3) failure.

Do not prematurely exit in case audit_open(3) fails, since all important
work is already done, but proceed with cleanup tasks.
