FOR RFC 6282 COMPLIANCE TODO: -Add compression options to UDP, currently only supports both ports compressed or both ports elided. | |
Pointers in the packetbuf buffer | |
Pointers in the sicslowpan and uip buffer |
Functions | |
static void | add_paging_dispatch (uint8_t page) |
Adds Paging dispatch byte. | |
static void | add_6lorh_hdr (void) |
Adds 6lorh headers before IPHC. | |
static void | digest_paging_dispatch (void) |
Digest 6lorh headers before IPHC. | |
static void | digest_6lorh_hdr (void) |
Digest 6lorh headers before IPHC. | |
IPHC related functions | |
| |
static struct sicslowpan_addr_context * | addr_context_lookup_by_prefix (uip_ipaddr_t *ipaddr) |
find the context corresponding to prefix ipaddr | |
static struct sicslowpan_addr_context * | addr_context_lookup_by_number (uint8_t number) |
find the context with the given number | |
static int | compress_hdr_iphc (void) |
Compress IP/UDP header. | |
static bool | uncompress_hdr_iphc (uint8_t *buf, uint16_t buf_size, uint16_t ip_len) |
Uncompress IPHC (i.e., IPHC and LOWPAN_UDP) headers and put them in sicslowpan_buf. | |
IPv6 dispatch "compression" function | |
| |
Input/output functions common to all compression schemes | |
| |
static void | packet_sent (void *ptr, int status, int transmissions) |
Callback function for the MAC packet sent callback. | |
static void | send_packet (void) |
This function is called by the 6lowpan code to send out a packet. | |
static uint8_t | output (const linkaddr_t *localdest) |
Take an IP packet and format it to be sent on an 802.15.4 network using 6lowpan. | |
static void | input (void) |
Process a received 6lowpan packet. | |
Variables | |
General variables | |
static uint8_t * | packetbuf_ptr |
A pointer to the packetbuf buffer. | |
static uint8_t | packetbuf_hdr_len |
packetbuf_hdr_len is the total length of (the processed) 6lowpan headers (fragment headers, IPV6 or HC1, HC2, and HC1 and HC2 non compressed fields). | |
static int | packetbuf_payload_len |
The length of the payload in the Packetbuf buffer. | |
static uint8_t | uncomp_hdr_len |
uncomp_hdr_len is the length of the headers before compression (if HC2 is used this includes the UDP header in addition to the IP header). | |
static int | mac_max_payload |
mac_max_payload is the maimum payload space on the MAC frame. | |
static uint8_t | curr_page |
The current page (RFC 4944) | |
static int | last_tx_status |
the result of the last transmitted fragment | |
variables specific to RFC 6282 | |
static uint8_t * | iphc_ptr |
Addresses contexts for IPHC. | |
