Detailed Description
Application layered TCP/TLS connection API (to be used from TCPIP thread)
This file provides a TLS layer using mbedTLS

Function Documentation
| static int altcp_mbedtls_bio_recv | ( | void * | ctx, |
| unsigned char * | buf, | ||
| size_t | len | ||
| ) | [static] |
Receive callback function called from mbedtls (set via mbedtls_ssl_set_bio) This function mainly copies data from pbufs and frees the pbufs after copying.
Definition at line 438 of file altcp_tls_mbedtls.c.
| static int altcp_mbedtls_bio_send | ( | void * | ctx, |
| const unsigned char * | dataptr, | ||
| size_t | size | ||
| ) | [static] |
Send callback function called from mbedtls (set via mbedtls_ssl_set_bio) This function is either called during handshake or when sending application data via altcp_mbedtls_write (or altcp_write)
Definition at line 1088 of file altcp_tls_mbedtls.c.
| static err_t altcp_mbedtls_lower_accept | ( | void * | arg, |
| struct altcp_pcb * | accepted_conn, | ||
| err_t | err | ||
| ) | [static] |
Accept callback from lower connection (i.e.
TCP) Allocate one of our structures, assign it to the new connection's 'state' and call the new connection's 'accepted' callback. If that succeeds, we wait to receive connection setup handshake bytes from the client.
Definition at line 126 of file altcp_tls_mbedtls.c.
| static err_t altcp_mbedtls_lower_connected | ( | void * | arg, |
| struct altcp_pcb * | inner_conn, | ||
| err_t | err | ||
| ) | [static] |
Connected callback from lower connection (i.e.
TCP). Not really implemented/tested yet...
Definition at line 151 of file altcp_tls_mbedtls.c.
| static err_t altcp_mbedtls_lower_poll | ( | void * | arg, |
| struct altcp_pcb * | inner_conn | ||
| ) | [static] |
Poll callback from lower connection (i.e.
TCP) Just pass this on to the application.
Definition at line 519 of file altcp_tls_mbedtls.c.
| static err_t altcp_mbedtls_lower_recv | ( | void * | arg, |
| struct altcp_pcb * | inner_conn, | ||
| struct pbuf * | p, | ||
| err_t | err | ||
| ) | [static] |
Recv callback from lower connection (i.e.
TCP) This one mainly differs between connection setup/handshake (data is fed into mbedTLS only) and application phase (data is decoded by mbedTLS and passed on to the application).
Definition at line 184 of file altcp_tls_mbedtls.c.
| static err_t altcp_mbedtls_lower_sent | ( | void * | arg, |
| struct altcp_pcb * | inner_conn, | ||
| u16_t | len | ||
| ) | [static] |
Sent callback from lower connection (i.e.
TCP) This only informs the upper layer to try to send more, not about the number of ACKed bytes.
Definition at line 492 of file altcp_tls_mbedtls.c.
| static u16_t altcp_mbedtls_sndbuf | ( | struct altcp_pcb * | conn ) | [static] |
Allow caller of altcp_write() to limit to negotiated chunk size or remaining sndbuf space of inner_conn.
Definition at line 992 of file altcp_tls_mbedtls.c.
| static err_t altcp_mbedtls_write | ( | struct altcp_pcb * | conn, |
| const void * | dataptr, | ||
| u16_t | len, | ||
| u8_t | apiflags | ||
| ) | [static] |
Write data to a TLS connection.
Calls into mbedTLS, which in turn calls into altcp_mbedtls_bio_send() to send the encrypted data
Definition at line 1031 of file altcp_tls_mbedtls.c.
| static struct altcp_tls_config* altcp_tls_create_config | ( | int | is_server, |
| int | have_cert, | ||
| int | have_pkey, | ||
| int | have_ca | ||
| ) | [static, read] |
Create new TLS configuration ATTENTION: Server certificate and private key have to be added outside this function!
Definition at line 673 of file altcp_tls_mbedtls.c.
| static int dummy_rng | ( | void * | ctx, |
| unsigned char * | buffer, | ||
| size_t | len | ||
| ) | [static] |
ATTENTION: It is *really* important to *NOT* use this dummy RNG in production code!!!!
