Detailed Description

This code implements a variety of utility functions related to the OSMUX user-plane multiplexing protocol, an efficient alternative to plain UDP/RTP streams for voice transport in back-haul of cellular networks.

For information about the OSMUX protocol design, please see the OSMUX reference manual at http://ftp.osmocom.org/docs/latest/osmux-reference.pdf

Function Documentation

◆ osmux_snprintf()

int osmux_snprintf ( char *  buf,
size_t  size,
struct msgb *  msg 
)

Print osmux header fields and payload from msg into buffer buf.

Parameters
[out]bufbuffer to store the output into
[in]lenlength of buf in bytes
[in]msgbmessage buffer containing one or more osmux frames
Returns
the number of characters printed (excluding the null byte used to end output to strings).

If the output was truncated due to this limit, then the return value is the number of characters (excluding the terminating null byte) which would have been written to the final string if enough space had been available.

◆ osmux_xfrm_input()

int osmux_xfrm_input ( struct osmux_in_handle *  h,
struct msgb *  msg,
int  ccid 
)

osmux_xfrm_input - add RTP message to OSmux batch

Parameters
msgRTP message that you want to batch into one OSmux message

If 0 is returned, this indicates that the message has been batched and the msgb is now owned by the osmux layer. If negative value is returned, an error occurred and the message has been dropped (and freed). If 1 is returned, you have to invoke osmux_xfrm_input_deliver and try again.

The function takes care of releasing the messages in case of error and when building the batch.

◆ osmux_xfrm_input_alloc()

struct osmux_in_handle * osmux_xfrm_input_alloc ( void *  ctx)

Allocate a new osmux in handle (osmux source, tx side)

Parameters
[in]ctxtalloc context to use when allocating the returned struct
Returns
Allocated osmux in handle

This object contains configuration and state to handle a group of circuits (trunk), receiving RTP packets from the upper layer (API user) and sending batched & trunked Osmux messages containing all the data of those circuits down the stack outgoing network Osmux messages. Returned pointer can be freed with regular talloc_free, all pending messages in queue and all internal data will be freed.

◆ osmux_xfrm_input_fini()

void osmux_xfrm_input_fini ( struct osmux_in_handle *  h)
Deprecated:
: Use talloc_free() instead (will call osmux_xfrm_input_talloc_destructor())

◆ osmux_xfrm_input_init()

void osmux_xfrm_input_init ( struct osmux_in_handle *  h)
Deprecated:
: Use osmux_xfrm_input_alloc() instead

◆ osmux_xfrm_output_alloc()

struct osmux_out_handle * osmux_xfrm_output_alloc ( void *  ctx)

Allocate a new osmux out handle.

Parameters
[in]ctxtalloc context to use when allocating the returned struct
Returns
Allocated osmux out handle

This object contains configuration and state to handle a specific CID in incoming network Osmux messages, repackaging the frames for that CID as RTP packets and pushing them up the protocol stack. Returned pointer can be freed with regular talloc_free, queue will be flushed and all internal data will be freed.

◆ osmux_xfrm_output_flush()

void osmux_xfrm_output_flush ( struct osmux_out_handle *  h)

Flush all scheduled RTP packets still pending to be transmitted.

Parameters
[in]hthe osmux out handle to flush

This function will immediately call the transmit callback for all queued RTP packets, making sure the list ends up empty. It will also stop all internal timers to make sure the osmux_out_handle can be dropped or re-used by calling osmux_xfrm_output on it.

◆ osmux_xfrm_output_init()

void osmux_xfrm_output_init ( struct osmux_out_handle *  h,
uint32_t  rtp_ssrc 
)
Deprecated:
: Use osmux_xfrm_output_alloc() and osmux_xfrm_output_set_rtp_*() instead

◆ osmux_xfrm_output_init2()

void osmux_xfrm_output_init2 ( struct osmux_out_handle *  h,
uint32_t  rtp_ssrc,
uint8_t  rtp_payload_type 
)
Deprecated:
: Use osmux_xfrm_output_alloc() and osmux_xfrm_output_set_rtp_*() instead

◆ osmux_xfrm_output_sched()

int osmux_xfrm_output_sched ( struct osmux_out_handle *  h,
struct osmux_hdr *  osmuxh 
)

Generate RTP packets from osmux frame AMR payload set and schedule them for transmission at appropriate time.

Parameters
[in]hthe osmux out handle handling a specific CID
[in]osmuxhBuffer pointing to osmux frame header structure and AMR payload
Returns
Number of generated RTP packets

The osmux frame passed to this function must be of the type OSMUX_FT_VOICE_AMR. The generated RTP packets are kept into h's internal list and sent to the callback configured through osmux_xfrm_output_set_tx_cb when are ready to be transmitted according to schedule.

◆ osmux_xfrm_output_set_rtp_msgb_alloc_cb()

void osmux_xfrm_output_set_rtp_msgb_alloc_cb ( struct osmux_out_handle *  h,
rtp_msgb_alloc_cb_t  cb,
void *  cb_data 
)

Set callback to call when an RTP packet to be generated is to be allocated.

Parameters
[in]hthe osmux out handle handling a specific CID
[in]cbUser defined msgb alloc function for generated RTP pkts
[in]cb_dataOpaque data pointer set by user and passed in cb
Returns
msgb structure to be used to fill in generated RTP pkt content

◆ osmux_xfrm_output_set_rtp_pl_type()

void osmux_xfrm_output_set_rtp_pl_type ( struct osmux_out_handle *  h,
uint32_t  rtp_payload_type 
)

Set Payload Type of generated RTP packets from Osmux frames.

Parameters
[in]hthe osmux out handle handling a specific CID
[in]rtp_payload_typethe RTP Payload Type to set

◆ osmux_xfrm_output_set_rtp_ssrc()

void osmux_xfrm_output_set_rtp_ssrc ( struct osmux_out_handle *  h,
uint32_t  rtp_ssrc 
)

Set SSRC of generated RTP packets from Osmux frames.

Parameters
[in]hthe osmux out handle handling a specific CID
[in]rtp_ssrcthe RTP SSRC to set

◆ osmux_xfrm_output_set_tx_cb()

void osmux_xfrm_output_set_tx_cb ( struct osmux_out_handle *  h,
void(*)(struct msgb *msg, void *data)  tx_cb,
void *  data 
)

Set transmission callback to call when a generated RTP packet is to be transmitted.

Parameters
[in]hthe osmux out handle handling a specific CID
[in]osmuxhBuffer pointing to osmux frame header structure and AMR payload
Returns
Number of generated RTP packets

This Function sets the callback called by the interal timer set by osmux_xfrm_out_sched function.

    Detailed Description

    This code is intended to abstract any client use of stream-type sockets, such as TCP and SCTP.

    An osmo_stream_cli represents a client implementation of a SOCK_STREAM or SOCK_SEQPACKET socket. It contains all the common logic like non-blocking outbound connect to a remote server, re-connecting after disconnect or connect failure, etc.

    osmo_stream_cli can operate in two different modes:

    1. The legacy mode using osmo_fd (from libosmocore)
    2. The modern (2023) mode using osmo_io_fd (from libosmocore)

    For any new applications, you definitely should use the modern mode, as it provides you with a higher layer of abstraction and allows you to perform efficient I/O using the io_uring backend of osmo_io.

    The modern mode is chosen by invoking osmo_stream_cli_set_read_cb2(). The legacy mode is chosen by invoking the older osmo_stream_cli_set_read_cb().

    A typical usage of osmo_stream_cli would look as follows:

    Once the connection is established, your connect_cb is called to notify you.

    You may send data to the connection using osmo_tream_cli_send().

    Any received inbound data on the connection is reported vie the read_cb.

    ◆ osmo_stream_cli_open()

    int osmo_stream_cli_open ( struct osmo_stream_cli *  cli)

    Open connection of an Osmocom stream client.

    This will initiate an non-blocking outbound connect to the configured destination (server) address. By default the client will automatically attempt to reconnect after default timeout. To disable this, use osmo_stream_cli_set_reconnect_timeout() before calling this function.

    Parameters
    [in]cliStream Client to connect
    Returns
    negative on error, 0 on success

    ◆ osmo_stream_cli_open2()

    int osmo_stream_cli_open2 ( struct osmo_stream_cli *  cli,
    int  reconnect 
    )

    DEPRECATED: use osmo_stream_cli_set_reconnect_timeout() or osmo_stream_cli_reconnect() instead! Open connection of an Osmocom stream client.

    Parameters
    [in]cliStream Client to connect
    [in]reconect1 if we should not automatically reconnect
    Returns
    negative on error, 0 on success

    ◆ osmo_stream_cli_reconnect()

    void osmo_stream_cli_reconnect ( struct osmo_stream_cli *  cli)

    Re-connect an Osmocom Stream Client.

    If re-connection is enabled for this client (which is the case unless negative timeout was explicitly set via osmo_stream_cli_set_reconnect_timeout() call), we close any existing connection (if any) and schedule a re-connect timer

    ◆ osmo_stream_cli_recv()

    int osmo_stream_cli_recv ( struct osmo_stream_cli *  cli,
    struct msgb *  msg 
    )

    Receive data via an Osmocom stream client in osmo_fd mode.

    Parameters
    [in]cliStream Client through which we want to send
    msgpre-allocate message buffer to which received data is appended
    Returns
    number of bytes read; <=0 in case of error

    Application programs using the legacy osmo_fd mode of osmo_stream_cli will use this function to read/receive from a stream client socket after they have been notified that it is readable (via select/poll).

    If conn is an SCTP connection, additional specific considerations shall be taken:

    • msg->cb is always filled with SCTP ppid, and SCTP stream values, see msgb_sctp_*() APIs.
    • If an SCTP notification was received when reading from the SCTP socket, msgb_sctp_msg_flags(msg) will contain bit flag OSMO_STREAM_SCTP_MSG_FLAGS_NOTIFICATION set, and the msgb will contain a "union sctp_notification" instead of user data. In this case the return code will be either 0 (if conn is considered dead after the notification) or -EAGAIN (if conn is considered still alive after the notification) resembling the standard recv() API.

    ◆ osmo_stream_cli_send()

    void osmo_stream_cli_send ( struct osmo_stream_cli *  cli,
    struct msgb *  msg 
    )

    Enqueue data to be sent via an Osmocom stream client.

    This is the function you use for writing/sending/transmitting data via the osmo_stream_cli.

    Parameters
    [in]cliStream Client through which we want to send
    [in]msgMessage buffer to enqueue in transmit queue

    Detailed Description

    Function Documentation

    ◆ osmo_jibuf_alloc()

    struct osmo_jibuf * osmo_jibuf_alloc ( void *  talloc_ctx)

    Allocate a new jitter buffer instance.

    Returns
    the new allocated instance

    ◆ osmo_jibuf_delete()

    void osmo_jibuf_delete ( struct osmo_jibuf *  jb)

    Destroy a previously allocated jitter buffer instance.

    Parameters
    [in]jbPreviously allocated (non-null) jitter buffer instance

    All the queued packets are dequeued before deleting the instance.

    ◆ osmo_jibuf_empty()

    bool osmo_jibuf_empty ( struct osmo_jibuf *  jb)

    Check whether the jitter buffer instance has packets queued or not.

    Parameters
    [in]jbjitter buffer instance
    Returns
    true if the queue is empty, false otherwise.

    ◆ osmo_jibuf_enable_skew_compensation()

    void osmo_jibuf_enable_skew_compensation ( struct osmo_jibuf *  jb,
    bool  enable 
    )

    Toggle use of skew detection and compensation mechanism.

    Parameters
    [in]jbjitter buffer instance
    [in]enableWhether to enable or not (default) the skew estimation and compensation mechanism

    When this function is called, the estimated skew is reset.

    ◆ osmo_jibuf_enqueue()

    int osmo_jibuf_enqueue ( struct osmo_jibuf *  jb,
    struct msgb *  msg 
    )

    Try to enqueue a packet into the jitter buffer.

    Parameters
    [in]jbjitter buffer instance
    [in]msgmsgb to enqueue, containing an RTP packet
    Returns
    <0 if the packet was dropped, 0 otherwise

    This function calculates the delay for the enqueued packet. If the delay is bigger than the current buffer size, the function returns -1 and the caller owns the packet again and can free it if required. If the packet is enqueued, 0 is returned and the exact same packet (ownership transfer, no copy is made) will be available again through the dequeue_cb() when the queue timer for this packet expires.

    ◆ osmo_jibuf_set_dequeue_cb()

    void osmo_jibuf_set_dequeue_cb ( struct osmo_jibuf *  jb,
    osmo_jibuf_dequeue_cb  dequeue_cb,
    void *  cb_data 
    )

    Set dequeue callback for the jitter buffer.

    Parameters
    [in]jbjitter buffer instance
    [in]dequeue_cbfunction pointer to call back when the dequeue timer for a given packet expires
    [in]cb_datadata pointer to be passed to dequeue_cb together with the msgb.

    ◆ osmo_jibuf_set_max_delay()

    void osmo_jibuf_set_max_delay ( struct osmo_jibuf *  jb,
    uint32_t  max_delay 
    )

    Set maximum buffer size for the jitter buffer.

    Parameters
    [in]jbjitter buffer instance
    [in]max_delayMaximum buffer size, as in maximum delay in milliseconds

    ◆ osmo_jibuf_set_min_delay()

    void osmo_jibuf_set_min_delay ( struct osmo_jibuf *  jb,
    uint32_t  min_delay 
    )

    Set minimum buffer size for the jitter buffer.

    Parameters
    [in]jbjitter buffer instance
    [in]min_delayMinimum buffer size, as in minimum delay in milliseconds

    Detailed Description

    This code is intended to abstract any server-side use of stream-type sockets, such as TCP and SCTP.

    The Osmocom stream socket helper is an abstraction layer for connected SOCK_STREAM/SOCK_SEQPACKET sockets. It encapsulates common functionality like binding, accepting client connections, etc.

    osmo_stream_srv can operate in two different modes:

    1. The legacy mode using osmo_fd (from libosmocore)
    2. The modern (2023) mode using osmo_io (from libosmocore)

    For any new applications, you definitely should use the modern mode, as it provides you with a higher layer of abstraction and allows you to perform efficient I/O using the io_uring backend of osmo_io.

    The modern mode is chosen by invoking osmo_stream_srv_create2(). The legacy mode is chosen by invoking the older osmo_stream_srv_create().

    The two main objects are osmo_stream_srv_link (main server accept()ing incoming connections) and osmo_stream_srv (a single given connection from a remote client).

    A typical stream_srv usage would look like this:

    Whenever a client connects to your listening socket, the connection will now be automatically accept()ed and the registered accept_cb call-back called. From within that accept_cb, you then

    Whenever data from a client arrives on a connection, your registered read_cb will be called together with a message buffer containing the received data. Ownership of the message buffer is transferred into the call-back, i.e. in your application. It's your responsibility to eventually msgb_free() it after usage.

    Whenever your application wants to transmit something to a given connection, it uses the osmo_stream_srv_send() function.

    struct osmo_stream_srv * osmo_stream_srv_create ( void *  ctx,
    struct osmo_stream_srv_link *  link,
    int  fd,
    osmo_stream_srv_read_cb_t  read_cb,
    osmo_stream_srv_closed_cb_t  closed_cb,
    void *  data 
    )

    Create a legacy osmo_fd mode Stream Server inside the specified link.

    This is the function an application traditionally calls from within the accept_cb call-back of the osmo_stream_srv_link. It creates a new osmo_stream_srv within that link.

    New users/programs should use osmo_stream_srv_create2 to operate in osmo_io mode instead.

    Parameters
    [in]ctxtalloc allocation context from which to allocate
    [in]linkStream Server Link to which we belong
    [in]fdsystem file descriptor of the new connection
    [in]read_cbCall-back to call when the socket is readable
    [in]closed_cbCall-back to call when the connection is closed
    [in]dataUser data to save in the new Stream Server struct
    Returns
    Stream Server in case of success; NULL on error

    ◆ osmo_stream_srv_create2()

    struct osmo_stream_srv_link *  link,
    int  fd,
    void *  data 
    )

    Create an osmo_iofd mode Stream Server inside the specified link.

    This is the function an application typically calls from within the accept_cb call-back of the osmo_stream_srv_link. It creates a new osmo_stream_srv in osmo_io mode within that link.

    Parameters
    [in]ctxtalloc allocation context from which to allocate
    [in]linkStream Server Link to which we belong

    Receive data via an Osmocom stream server in osmo_fd mode.

    Parameters
    [in]connStream Server from which to receive
    msgpre-allocate message buffer to which received data is appended
    Returns
    number of bytes read, negative on error.

    Application programs using the legacy osmo_fd mode of osmo_stream_srv will use this function to read/receive from a stream socket after they have been notified that it is readable (via select/poll).

    If conn is an SCTP connection, additional specific considerations shall be taken:

    • msg->cb is always filled with SCTP ppid, and SCTP stream values, see msgb_sctp_*() APIs.
    • If an SCTP notification was received when reading from the SCTP socket, msgb_sctp_msg_flags(msg) will contain bit flag OSMO_STREAM_SCTP_MSG_FLAGS_NOTIFICATION set, and the msgb will contain a "union sctp_notification" instead of user data. In this case the return code will be either 0 (if conn is considered dead after the notification) or -EAGAIN (if conn is considered still alive after the notification) resembling the standard recv() API.

    ◆ osmo_stream_srv_send()

    void osmo_stream_srv_send ( struct osmo_stream_srv *  conn,
    struct msgb *  msg 
    )

    osmo_stream_srv_closed_cb_t  closed_cb 
    )

    Set the call-back function called when the stream server socket was closed.

    Whenever the socket was closed (network error, client disconnect, etc.), the user-provided call-back function given here is called. This is typically used by the application to clean up any of its internal state related to this specific client/connection.

    [in]connserver whose name is to be set. The name is copied into the osmo_stream_srv_link, so the caller memory is not required to be valid beyond the call of this function.
    [in]namethe name to be set on conn

    ◆ osmo_stream_srv_set_read_cb()

    void osmo_stream_srv_set_read_cb ( struct osmo_stream_srv *  conn,
    osmo_stream_srv_read_cb2_t  read_cb 
    )

    Set the call-back function for incoming data on an osmo_io stream_srv.

    This function only works with osmo_stream_srv in osmo_io mode, created by osmo_stream_srv_create2()!

    Whenever data is received on the osmo_stram_srv, the read_cb call-back function of the user application is called.

    Parameters
    [in]connStream Server to modify
    [in]read_cbCall-back function to be called when data was read

    ◆ osmo_stream_srv_set_segmentation_cb()

    void osmo_stream_srv_set_segmentation_cb ( struct osmo_stream_srv *  conn,

    )

    Set the segmentation callback for target osmo_stream_srv structure.

    Parameters
    [in,out]connTarget Stream Server to modify
    [in]segmentation_cbSegmentation callback to be set

    A segmentation call-back can optionally be used when a packet based protocol (like TCP) is used within a STREAM style socket that does not preserve message boundaries within the stream. If a segmentation call-back is given, the osmo_stream_srv library code will makes sure that the read_cb called only for complete single messages, and not arbitrary segments of the stream.

    This function only works with osmo_stream_srv in osmo_io mode, created by osmo_stream_srv_create2()! The connection has to have been established prior to calling this function.

    ◆ osmo_stream_srv_set_segmentation_cb2()

    void osmo_stream_srv_set_segmentation_cb2 ( struct osmo_stream_srv *  conn,
    osmo_stream_srv_segmentation_cb2_t  segmentation_cb2 
    )

    Set the segmentation callback for target osmo_stream_srv structure.

    Parameters
    [in,out]connTarget Stream Server to modify
    [in]segmentation_cb2Segmentation callback to be set

    Same as osmo_stream_srv_set_segmentation_cb(), but a osmo_stream_srv_segmentation_cb2_t is called instead which allows access to the related conn object.
