◆ pcmk__crm_ipc_is_authentic_process()

int pcmk__crm_ipc_is_authentic_process	(	qb_ipcc_connection_t *	qb_ipc,
		int	sock,
		uid_t	refuid,
		gid_t	refgid,
		pid_t *	gotpid,
		uid_t *	gotuid,
		gid_t *	gotgid
	)

Check the authenticity of the IPC socket peer process.

If everything goes well, peer's authenticity is verified by the means of comparing against provided referential UID and GID (either satisfies), and the result of this check can be deduced from the return value. As an exception, detected UID of 0 ("root") satisfies arbitrary provided referential daemon's credentials.

Parameters

[in]	qb_ipc	libqb client connection if available
[in]	sock	IPC related, connected Unix socket to check peer of
[in]	refuid	referential UID to check against
[in]	refgid	referential GID to check against
[out]	gotpid	to optionally store obtained PID of the peer (not available on FreeBSD, special value of 1 used instead, and the caller is required to special case this value respectively)
[out]	gotuid	to optionally store obtained UID of the peer
[out]	gotgid	to optionally store obtained GID of the peer

Returns: Standard Pacemaker return code ie: 0 if it the connection is authentic pcmk_rc_ipc_unauthorized if the connection is not authentic, standard errors.

Note: While this function is tolerant on what constitutes authorized IPC daemon process (its effective user matches UID=0 or refuid, or at least its group matches refgid), either or both (in case of UID=0) mismatches on the expected credentials of such peer process shall be investigated at the caller when value of 1 gets returned there, since higher-than-expected privileges in respect to the expected/intended credentials possibly violate the least privilege principle and may pose an additional risk (i.e. such accidental inconsistency shall be eventually fixed).
