add support for audit container identifier
Subsystems (2)
v7 cover add support for audit container identifier
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 and 11th add audit netlink support for setting and getting contid, loginuid and sessionid preparing to deprecate the /proc interface.
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.

PATCH v7 3/12 auditctl: add support for AUDIT_CONTID filter
In reply to Richard Guy BriggsA u64 container identifier has been added to the kernel view of tasks. This allows container orchestrators to label tasks with a unique tamperproof identifier that gets inherited by its children to be able to track the provenance of actions by a container.
Add support to libaudit and auditctl for the AUDIT_CONTID field to filter based on audit container identifier. This field is specified with the "contid" field name on the command line.
Since it is a u64 and larger than any other numeric field, send it as a string but do the appropriate conversions on each end in each direction.

Re: [PATCH ghau51/ghau40 v7 04/12] add ausearch containerid support
Quoted 2 lines · Richard Guy Briggs
Add support to ausearch for searching on the containerid field in records.
Steve, I'm expecting that you may be able to help here on ausearch. The problem is I've modelled this search code on expecting only one value to be delivered in the contid= field in CONTAINER_OP and CONTAINER_ID records. In the case of the latter type of record, the value could either be a CSV list or a nested list (separated by ^), so the value stored in "s->contid" (or l->s.contid) would need to be more complex and the check against it no longer a simple equality check but rather a parse and check of each listed value for a match.
Do you have a way to do that already in other fields that I could use as a current best practice, or shall I work on a method myself?
The CSV search will be necessary to support network namespace container events and the nesting will be necessary only if the nesting feature and reporting method are accepted.

PATCH v7 6/12 libaudit: add support to get the task audit container identifier
In reply to Richard Guy BriggsAdd the audit_get_containerid() call analogous to audit_getloginuid() and audit_get_session() calls to get our own audit container identifier.
This is intended as a debug patch, not to be upstreamed.

PATCH v7 8/12 add support for audit_signal_info2
In reply to Richard Guy BriggsSince a process in a container could potentially signal the audit daemon (reconfig, terminate, roll log, resume), that audit container identifier information should be made available to the audit daemon to report the full provenance of the signal. It is not possible to add it to the existing audit_signal_info struct without causing a kABI change. Introduce a new audit message type AUDIT_SIGNAL_INFO2 using a new audit_sig_info2 struct to be able to transfer this information from kernel to userspace.
struct audit_sig_info2 {
uid_t uid;
pid_t pid;
uint64_t cid;
char ctx[0];

PATCH v7 10/12 contid: switch from /proc to netlink
In reply to Richard Guy BriggsAdd the ability to get and set the audit container identifier using an audit netlink message using message types AUDIT_SET_CONTID 1023 and AUDIT_GET_CONTID 1022 in addition to using the proc filesystem. The message format includes the data structure:
struct audit_contid_status {
pid_t pid;
u64 id;
};This switches over the audit_set_containerid() and audit_get_containerid() to use this method if it exists.

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 and 11th add audit netlink support for setting and getting contid, loginuid and sessionid preparing to deprecate the /proc interface.
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.
