Function Documentation

acltoownermode()

int acltoownermode	(	const AFPObj *	obj,
		const struct vol *	vol,
		char *	path,
		struct stat *	st,
		struct maccess *	ma )

map ACL to user maccess

This is the magic function that makes ACLs usable by calculating the access granted by ACEs to the logged in user.

afp_access()

int afp_access	(	AFPObj *	obj,
		char *	ibuf,
		size_t ibuflen	_U_,
		char *rbuf	_U_,
		size_t *	rbuflen )

afp_getacl()

int afp_getacl	(	AFPObj *	obj,
		char *	ibuf,
		size_t ibuflen	_U_,
		char *rbuf	_U_,
		size_t *	rbuflen )

afp_setacl()

int afp_setacl	(	AFPObj *	obj,
		char *	ibuf,
		size_t ibuflen	_U_,
		char *rbuf	_U_,
		size_t *	rbuflen )

check_acl_access()

int check_acl_access ( const AFPObj * obj, const struct vol * vol, struct dir * dir, const char * path, const uuidp_t uuid, uint32_t requested_rights )

static

Checks if a given UUID has requested_rights(type darwin_ace_rights) for path.

Note: this gets called frequently and is a good place for optimizations !

Parameters

obj	(r) AFP object
vol	(r) volume
dir	(rw) directory
path	(r) path to filesystem object
uuid	(r) UUID of user
requested_rights	(r) requested Darwin ACE

Returns

AFP result code

get_and_map_acl()

int get_and_map_acl ( char * name, char * rbuf, size_t * rbuflen )

static

map_acl()

int map_acl ( int type, void * acl, darwin_ace_t * buf, int ace_count )

static

remove_acl()

int remove_acl ( const struct vol * vol, const char * path, int dir )

static
