+ <para>The idmap_hash plugin implements a hashing algorithm used to map
+ SIDs for domain users and groups to 31-bit uids and gids, respectively.
This plugin also implements the nss_info API and can be used
to support a local name mapping files if enabled via the
- "winbind normlaize names" and "winbind nss info"
+ "winbind normalize names" and "winbind nss info"
parameters in smb.conf.

+
+Basic design of the tsocket abstraction
+=======================================
+
+The tsocket layer is designed to match more or less
+the bsd socket layer, but it hides the filedescriptor
+within a opaque 'tsocket_context' structure to make virtual
+sockets possible. The virtual sockets can be encrypted tunnels
+(like TLS, SASL or GSSAPI) or named pipes over smb.
+
+The tsocket layer is a bit like an abstract class, which defines
+common methods to work with sockets in a non blocking fashion.
+
+The whole library is based on the talloc(3) and 'tevent' libraries.
+
+The 'tsocket_address' structure is the 2nd abstracted class
+which represends the address of a socket endpoint.
+
+Each different type of socket has its own constructor.
+
+Typically the constructor for a tsocket_context is attached to
+the tsocket_address of the source endpoint. That means
+the tsocket_address_create_socket() function takes the
+tsocket_address of the local endpoint and creates a tsocket_context
+for the communication.
+
+For some usecases it's possible to wrap an existing socket into a
+tsocket_context, e.g. to wrap an existing pipe(2) into
+tsocket_context, so that you can use the same functions to
+communicate over the pipe.
+
+The tsocket_address abstraction
+===============================
+
+The tsocket_address represents an socket endpoint genericly.
+As it's like an abstract class it has no specific constructor.
+The specific constructors are descripted later sections.
+
+There's a function get the string representation of the
+endpoint for debugging. Callers should not try to parse
+the string! The should use additional methods of the specific
+tsocket_address implemention to get more details.
+
+ char *tsocket_address_string(const struct tsocket_address *addr,
+ TALLOC_CTX *mem_ctx);
+
+There's a function to create a copy of the tsocket_address.
+This is useful when before doing modifications to a socket
+via additional methods of the specific tsocket_address implementation.
+
+ struct tsocket_address *tsocket_address_copy(const struct tsocket_address *addr,
+ TALLOC_CTX *mem_ctx);
+
+There's a function to create a tsocket_context based on the given local
+socket endpoint. The return value is 0 on success and -1 on failure
+with errno holding the specific error. Specific details are descripted in later
+sections. Note not all specific implementation have to implement all socket
+types.
+
+ enum tsocket_type {
+ TSOCKET_TYPE_STREAM = 1,
+ TSOCKET_TYPE_DGRAM,
+ TSOCKET_TYPE_MESSAGE
+ };
+
+ int tsocket_address_create_socket(const struct tsocket_address *addr,
+ enum tsocket_type type,
+ TALLOC_CTX *mem_ctx,
+ struct tsocket_context **sock);
+
+The tsocket_context abstraction
+===============================
+
+The tsocket_context is like an abstract class and represents
+a socket similar to bsd style sockets. The methods are more
+or less equal to the bsd socket api, while the filedescriptor
+is replaced by tsocket_context and sockaddr, socklen_t pairs
+are replaced by tsocket_address. The 'bind' operation happens
+in the specific constructor as the constructor is typically based
+on tsocket_address of local socket endpoint.
+
+All operations are by design non blocking and can return error
+values like EAGAIN, EINPROGRESS, EWOULDBLOCK or EINTR which
+indicate that the caller should retry the operation later.
+Also read the "The glue to tevent" section.
+
+The socket can of types:
+ - TSOCKET_TYPE_STREAM is the equivalent to SOCK_STREAM in the bsd socket api.
+ - TSOCKET_TYPE_DGRAM is the equivalent to SOCK_DGRAM in the bsd socket api.
+ - TSOCKET_TYPE_MESSAGE operates on a connected socket and is therefore
+ like TSOCKET_TYPE_STREAM, but the consumer needs to first read all
+ data of a message, which was generated by one message 'write' on the sender,
+ before the consumer gets data of the next message. This matches a bit
+ like message mode pipes on windows. The concept is to transfer ordered
+ messages between to endpoints.
+
+There's a function to connect to a remote endpoint. The behavior
+and error codes match the connect(2) function of the bsd socket api.
+Maybe the specific tsocket_context implementation speficied some
+further details.
+
+ int tsocket_connect(struct tsocket_context *sock,
+ const struct tsocket_address *remote_addr);
+
+There's a function to listen for incoming connections. The behavior
+and error codes match the listen(2) function of the bsd socket api.
+Maybe the specific tsocket_context implementation speficied some
+further details.
+
+ int tsocket_listen(struct tsocket_context *sock,
+ int queue_size);
+
+There's a function to accept incoming connections. The behavior
+and error codes match the accept(2) function of the bsd socket api.
+Maybe the specific tsocket_context implementation speficied some
+further details.
+
+ int tsocket_accept(struct tsocket_context *sock,
+ TALLOC_CTX *mem_ctx,
+ struct tsocket_context **new_sock);
+
+There's a function to ask how many bytes are in input buffer
+of the connection. For sockets of type TSOCKET_TYPE_DGRAM or
+TSOCKET_TYPE_MESSAGE the size of the next available dgram/message
+is returned. A return value of -1 indicates a socket error
+and errno will hold the specific error code. If no data
+is available 0 is returned, but retry error codes like
+EINTR can also be returned.
+
+ ssize_t tsocket_pending(struct tsocket_context *sock);
+
+There's a function to read data from the socket. The behavior
+and error codes match the readv(3) function, also take a look
+at the recv(2) function of the bsd socket api.
+Maybe the specific tsocket_context implementation speficied some
+further details.
+
+ int tsocket_readv(struct tsocket_context *sock,
+ const struct iovec *vector, size_t count);
+
+There's a function to write data from the socket. The behavior
+and error codes match the writev(3) function, also take a look
+at the send(2) function of the bsd socket api.
+Maybe the specific tsocket_context implementation speficied some
+further details.
+
+ int tsocket_writev(struct tsocket_context *sock,
+ const struct iovec *vector, size_t count);
+
+There's a function to read a datagram from a remote endpoint.
+The behavior and error codes match the recvfrom(2) function of
+the bsd socket api. As TSOCKET_TYPE_DGRAM sockets can also be
+used in connected mode src_addr can be NULL, if the caller don't
+want to get the source address. Maybe the specific tsocket_context
+implementation speficied some further details.
+
+ ssize_t tsocket_recvfrom(struct tsocket_context *sock,
+ uint8_t *data, size_t len,
+ TALLOC_CTX *addr_ctx,
+ struct tsocket_address **src_addr);
+
+There's a function to send a datagram to a remote endpoint the socket.
+The behavior and error codes match the recvfrom(2) function of the
+bsd socket api. As TSOCKET_TYPE_DGRAM sockets can also be used in
+connected mode dest_addr must be NULL in connected mode and a valid
+tsocket_address otherwise. Maybe the specific tsocket_context
+implementation speficied some further details.
+
+ ssize_t tsocket_sendto(struct tsocket_context *sock,
+ const uint8_t *data, size_t len,
+ const struct tsocket_address *dest_addr);
+
+There's a function to get the current status of the socket.
+The behavior and error codes match the getsockopt(2) function
+of the bsd socket api, with SOL_SOCKET and SO_ERROR as arguments.
+Maybe the specific tsocket_context implementation speficied some
+further details.
+
+ int tsocket_get_status(const struct tsocket_context *sock);
+
+There's a function to get tsocket_address of the local endpoint.
+The behavior and error codes match the getsockname(2) function
+of the bsd socket api. Maybe the specific tsocket_context
+implementation speficied some further details.
+
+ int tsocket_get_local_address(const struct tsocket_context *sock,
+ TALLOC_CTX *mem_ctx,
+ struct tsocket_address **local_addr);
+
+There's a function to get tsocket_address of the remote endpoint
+of a connected socket. The behavior and error codes match the
+getpeername(2) function of the bsd socket api. Maybe the specific
+tsocket_context implementation speficied some further details.
+
+ int tsocket_get_remote_address(const struct tsocket_context *sock,
+ TALLOC_CTX *mem_ctx,
+ struct tsocket_address **remote_addr,
+ const char *location);
+
+There's a function to ask for specific options of the socket.
+The behavior and error codes match the getsockopt(2) function
+of the bsd socket api. The option and value are represented as string
+values, where the 'value' parameter can be NULL is the caller don't want to
+get the value. The supported options and values are up to the specific
+tsocket_context implementation.
+
+ int tsocket_get_option(const struct tsocket_context *sock,
+ const char *option,
+ TALLOC_CTX *mem_ctx,
+ char **value);
+
+There's a function to set specific options of the socket.
+The behavior and error codes match the setsockopt(2) function
+of the bsd socket api. The option and value are represented as string
+values, where the 'value' parameter can be NULL. The supported options
+and values are up to the specific tsocket_context implementation.
+The 'force' parameter specifies whether an error should be returned
+for unsupported options.
+
+ int tsocket_set_option(const struct tsocket_context *sock,
+ const char *option,
+ bool force,
+ const char *value);
+
+There's a function to disconnect the socket. The behavior
+and error codes match the close(2) function of the bsd socket api.
+Maybe the specific tsocket_context implementation speficied some
+further details.
+
+ void tsocket_disconnect(struct tsocket_context *sock);
+
+The glue to tevent
+==================
+
+As the tsocket library is based on the tevent library,
+there need to be functions to let the caller register
+callback functions, which are triggered when the socket
+is writeable or readable. Typically one would use
+tevent fd events, but in order to hide the filedescriptor
+the tsocket_context abstraction has their own functions.
+
+There's a function to set the currently active tevent_context
+for the socket. It's important there's only one tevent_context
+actively used with the socket. A second call will cancel
+all low level events made on the old tevent_context, it will
+also resets the send and recv handlers to NULL. If the caller
+sets attaches a new event context to the socket, the callback
+function also need to be registered again. It's important
+that the caller keeps the given tevent_context in memory
+and actively calls tsocket_set_event_context(sock, NULL)
+before calling talloc_free(event_context).
+The function returns 0 on success and -1 together with an errno
+on failure.
+
+ int tsocket_set_event_context(struct tsocket_context *sock,
+ struct tevent_context *ev);
+
+There's a function to register a callback function which is called
+when the socket is readable. If the caller don't want to get notified
+anymore the function should be called with NULL as handler.
+The function returns 0 on success and -1 together with an errno
+on failure.
+
+ typedef void (*tsocket_event_handler_t)(struct tsocket_context *, void *);
+ int tsocket_set_readable_handler(struct tsocket_context *sock,
+ tsocket_event_handler_t handler,
+ void *private_data);
+
+There's a function to register a callback function which is called
+when the socket is writeable. If the caller don't want to get notified
+anymore the function should be called with NULL as handler.
+The function returns 0 on success and -1 together with an errno
+on failure.
+
+ typedef void (*tsocket_event_handler_t)(struct tsocket_context *, void *);
+ int tsocket_set_writeable_handler(struct tsocket_context *sock,
+ tsocket_event_handler_t handler,
+ void *private_data);
+
+Note: if the socket is readable and writeable, only the writeable
+ handler is called, this avoids deadlocks at the application level.
+
+Async helper functions
+======================
+
+To make the life easier for the callers, there're 'tevent_req' based
+helper functions for non-blocking io-operations. For each of this functions
+to work the caller must attach the tevent_context to the tsocket_context
+with tsocket_set_event_context(). Please remember that attching a new
+tevent_context will reset the event state of the socket and should only
+be done, when there's no async request is pending on the socket!
+
+The detailed calling conventions for 'tevent_req' based programming
+will be explained in the 'tevent' documentation.
+
+To receive the next availabe datagram from socket there's a wrapper
+for tsocket_recvfrom(). The caller virtually sends its desire to receive
+the next available datagram by calling the tsocket_recvfrom_send() function
+and attaches a callback function to the returned tevent_req via tevent_req_set_callback().
+The callback function is called when a datagram is available or an error has happened.
+The callback function needs to get the result by calling
+tsocket_recvfrom_recv(). The return value of tsocket_recvfrom_recv()
+matches the return value from tsocket_recvfrom(). A possible errno is delivered
+via the perrno parameter instead of the global errno variable. The datagram
+buffer and optional the source tsocket_address of the datagram are returned as talloc
+childs of the mem_ctx passed to tsocket_recvfrom_recv().
+It's important that the caller garanties that there's only one async
+read request on the socket at a time.
+
+ struct tevent_req *tsocket_recvfrom_send(struct tsocket_context *sock,
+ TALLOC_CTX *mem_ctx);
+ ssize_t tsocket_recvfrom_recv(struct tevent_req *req,
+ int *perrno,
+ TALLOC_CTX *mem_ctx,
+ uint8_t **buf,
+ struct tsocket_address **src);
+
+To send a datagram there's a wrapper for tsocket_sendto().
+The caller calls tsocket_sendto_send() instead of tsocket_sendto()
+which returns a tevent_req allocated on the given TALLOC_CTX.
+The caller attaches a callback function to the returned tevent_req via
+tevent_req_set_callback(). The callback function is called when a datagram was
+deliviered into the socket or an error has happened.
+The callback function needs to get the result by calling
+tsocket_sendto_recv(). The return value of tsocket_sendto_recv()
+matches the return value from tsocket_sendto(). A possible errno is delivered
+via the perrno parameter instead of the global errno variable.
+Normal callers should not use this function directly, they should use
+tsocket_sendto_queue_send/recv() instead.
+
+ struct tevent_req *tsocket_sendto_send(struct tsocket_context *sock,
+ TALLOC_CTX *mem_ctx,
+ const uint8_t *buf,
+ size_t len,
+ const struct tsocket_address *dst);
+ ssize_t tsocket_sendto_recv(struct tevent_req *req, int *perrno);
+
+As only one async tsocket_sendto() call should happen at a time,
+there's a 'tevent_queue' is used to serialize the sendto requests.
+
+ struct tevent_req *tsocket_sendto_queue_send(TALLOC_CTX *mem_ctx,
+ struct tsocket_context *sock,
+ struct tevent_queue *queue,
+ const uint8_t *buf,
+ size_t len,
+ struct tsocket_address *dst);
+ ssize_t tsocket_sendto_queue_recv(struct tevent_req *req, int *perrno);
+
+Ther's an async helper for tsocket_connect(), which should be used
+to connect TSOCKET_TYPE_STREAM based sockets.
+The caller virtually sends its desire to connect to the destination
+tsocket_address by calling tsocket_connect_send() and gets back a tevent_req.
+The caller sets a callback function via tevent_req_set_callback().
+The callback function is called if the tsocket is connected or an error has happened.
+The callback function needs to get the result by calling
+tsocket_connect_recv(). The return value of tsocket_connect_recv()
+matches the return value from tsocket_connect()/tsocket_get_status().
+A possible errno is delivered via the perrno parameter instead of the global
+errno variable.
+
+ struct tevent_req *tsocket_connect_send(struct tsocket_context *sock,
+ TALLOC_CTX *mem_ctx,
+ const struct tsocket_address *dst);
+ int tsocket_connect_recv(struct tevent_req *req, int *perrno);
+
+To send an 'iovec' there's a wrapper for tsocket_writev().
+The caller calls tsocket_writev_send() instead of tsocket_writev()
+which returns a tevent_req allocated on the given TALLOC_CTX.
+The caller attaches a callback function to the returned tevent_req via
+tevent_req_set_callback(). The callback function is called when the whole iovec
+was deliviered into the socket or an error has happened.
+The callback function needs to get the result by calling
+tsocket_writev_recv(). The return value of tsocket_writev_recv()
+matches the return value from tsocket_writev(). A possible errno is delivered
+via the perrno parameter instead of the global errno variable.
+Normal callers should not use this function directly, they should use
+tsocket_writev_queue_send/recv() instead.
+
+ struct tevent_req *tsocket_writev_send(struct tsocket_context *sock,
+ TALLOC_CTX *mem_ctx,
+ const struct iovec *vector,
+ size_t count);
+ int tsocket_writev_recv(struct tevent_req *req, int *perrno);
+
+As only one async tsocket_writev() call should happen at a time,
+there's a 'tevent_queue' is used to serialize the writev requests.
+
+ struct tevent_req *tsocket_writev_queue_send(TALLOC_CTX *mem_ctx,
+ struct tsocket_context *sock,
+ struct tevent_queue *queue,
+ const struct iovec *vector,
+ size_t count);
+ int tsocket_writev_queue_recv(struct tevent_req *req, int *perrno);
+
+For TSOCKET_TYPE_STREAM sockets, it's typically desired to split the stream
+into PDUs. That's why the helper function for tsocket_readv() is a bit
+different compared to the other helper functions. The general rule
+is still to get a tevent_req, set a callback which gets called when the
+operation is done. The callback function needs to get the result by
+calling tsocket_readv_recv(). The 'next_iovec' callback function
+makes the difference to the other helper function.
+The tsocket_writev_send/recv() logic asks the caller via the
+next_iovec_fn for an iovec array, which will be filled completely
+with bytes from the socket, then the next_iovec_fn is called for
+the next iovec array to fill, untill the next_iovec_fn returns an empty
+iovec array. That next_iovec_fn should allocate the array as child of the
+passed mem_ctx, while the buffers the array referr to belong to the caller.
+The tsocket_writev_send/recv() engine will modify and free the given array!
+The basic idea is that the caller allocates and maintains the real buffers.
+The next_iovec_fn should report error by returning -1 and setting errno to
+the specific error code. The engine will pass the error to the caller
+via tsocket_readv_recv().
+
+typedef int (*tsocket_readv_next_iovec_t)(struct tsocket_context *sock,
+ void *private_data,
+ TALLOC_CTX *mem_ctx,
+ struct iovec **vector,
+ size_t *count);
+struct tevent_req *tsocket_readv_send(struct tsocket_context *sock,
+ TALLOC_CTX *mem_ctx,
+ tsocket_readv_next_iovec_t next_iovec_fn,
+ void *private_data);
+int tsocket_readv_recv(struct tevent_req *req, int *perrno);
+
+Wrapper for BSD style sockets
+=============================
+
+Support for BSD style sockets of AF_INET, AF_INET6 and AF_UNIX
+are part of the main tsocket library.
+
+To wrap an existing fd into a tsocket_context the function
+tsocket_context_bsd_wrap_existing() can be used.
+The caller needs to make sure the fd is marked as non-blocking!
+Normaly the tsocket_disconnect() function would close the fd,
+but the caller can influence this behavior based on the close_on_disconnect
+parameter. The caller should also make sure that the socket is only
+accessed via the tsocket_context wrapper after the call to
+tsocket_context_bsd_wrap_existing().
+
+ int tsocket_context_bsd_wrap_existing(TALLOC_CTX *mem_ctx,
+ int fd, bool close_on_disconnect,
+ struct tsocket_context **_sock);
+
+To create a tsocket_address for an inet address you need to use
+the tsocket_address_inet_from_strings() function. It takes the family
+as parameter which can be "ipv4", "ipv6" or "ip", where "ip" autodetects
+"ipv4" or "ipv6", based on the given address string. Depending on the
+operating system, "ipv6" may not be supported. Note: NULL as address
+is mapped to "0.0.0.0" or "::" based on the given family.
+The address parameter only accepts valid ipv4 or ipv6 address strings
+and no names! The caller need to resolve names before using this function.
+
+ int tsocket_address_inet_from_strings(TALLOC_CTX *mem_ctx,
+ const char *family,
+ const char *address,
+ uint16_t port,
+ struct tsocket_address **addr);
+
+To get the address of the inet tsocket_address as string the
+tsocket_address_inet_addr_string() function should be used.
+The caller should not try to parse the tsocket_address_string() output!
+
+ char *tsocket_address_inet_addr_string(const struct tsocket_address *addr,
+ TALLOC_CTX *mem_ctx);
+
+To get the port number of the inet tsocket_address the
+tsocket_address_inet_port() function should be used.
+The caller should not try to parse the tsocket_address_string() output!
+
+ uint16_t tsocket_address_inet_port(const struct tsocket_address *addr);
+
+To alter the port number of an inet tsocket_address the
+tsocket_address_inet_set_port() function can be used.
+This is usefull if the caller gets the address from
+tsocket_address_copy(), tsocket_context_remote_address() or
+tsocket_context_remote_address() instead of tsocket_address_inet_from_strings().
+
+ int tsocket_address_inet_set_port(struct tsocket_address *addr,
+ uint16_t port);
+
+If the caller wants to create a broadcast socket, with the SO_BROADCAST
+socket option, the broadcast option needs to be set with the
+tsocket_address_inet_set_broadcast() function before calling
+tsocket_address_create_socket().
+
