Description Paul Moore 2015-09-04 14:37:41 UTC

Description of problem:
On occasion SELinux AVC denials are dropped by the audit subsystem during early boot without any warnings about dropped audit records. 

Additional info:
Reported as an issue with Android kernels but it is expected to be a problem with standard kernels as well.

Comment 1 Paul Moore 2015-09-04 14:42:49 UTC

I suspect this may be an issue with using the shared printk_ratelimit() limiter in audit_printk_skb() and audit_log_lost(); we probably should implement an audit specific rate limit to prevent other subsystems from squelching audit messages, especially those in audit_log_lost().

We are now tracking upstream bugs via GitHub:
