Here is the caller graph for this function:

◆ cf_file_check()

bool cf_file_check	(	CONF_PAIR *	cp,
		bool	check_perms
	)

Do some checks on the file as an "input" file.

i.e. one read by a module.

Note: Must be called with super user privileges.

Parameters

cp	currently being processed.
check_perms	If true - will return false if file is world readable, or not readable by the unprivileged user/group.

Returns

true if permissions are OK, or the file exists.
false if the file does not exist or the permissions are incorrect.

◆ cf_file_check_user()

void cf_file_check_user	(	uid_t	uid,

	)

Set the euid/egid used when performing file checks.

Sets the euid, and egid used when cf_file_check is called to check permissions on conf items of type CONF_FLAG_FILE_INPUT

Note: This is probably only useful for the freeradius daemon itself.

Parameters

uid	to set, (uid_t)-1 to use current euid.
gid	to set, (gid_t)-1 to use current egid.
