[PATCH ghau51/ghau40 v9 00/11] add support for audit container identifier
From: Richard Guy Briggs
Date: Sat Jun 27 2020 - 11:19:19 EST
Add support for audit kernel container identifiers to userspace tools.
The first and second add new record types. The third adds filter
support. The fourth and 5th start to add search support.
The 6th is to read the calling process' audit container identifier from
the /proc filesystem matching the kernel /proc read patch.
The 7th is to fix signal support and the 8th is to learn the audit
container identifier of the process that signals the audit daemon.
The 9th is a touch up to allow the contid field to be interpreted as a
CSV list.
The 10th adds audit contid list support to ausearch.
The last adds audit library support to allow a process to give
permission to a container orchestrator in a non-init user namespace via
audit netlink messages.
